COLLABORATIVE CO-DESIGN OF PORTABLE WORK BENEFITS POLICY MODEL AND NON-POLICY PROTOTYPE BASED ON DIRECT CARE WORKERS' NEEDS, ATTITUDES, AND BELIEFS
(2024) Kuo, Charlene C.; Aparicio, Elizabeth M.; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Direct care workers (DCWs) assist people with disabilities and frail elders with activities of daily living, thereby preventing institutionalization, hospitalization, and other costly medical services. From 2016 to 2060, the number of adults aged 65 and over is expected to increase from 49.2 million to 94.7 million. The number of adults 18 to 64 will remain the same, leading to a shortage of family caregivers. A shortage of family caregivers will require a robust direct care workforce. The direct care workforce is expected to grow by 1.3 million from 2019 to 2029 but this growth will not keep pace with the projected demand. The turnover rate among DCWs is high due to poor work conditions and inadequate compensation. Exploring ways to improve DCW working conditions and compensation is critical to prevent further shortages. DCWs' health is put at risk due to the nature of the work, low wages, and lack of worker protections and traditional work benefits. DCWs are vulnerable to injury, abuse, infectious diseases, and other poor health outcomes due to the previously listed disadvantages (Campbell, 2019c; Hughes, 2020; Jaffe, 2017; M. M. Quinn et al., 2016). DCWs in the United States are predominantly women, members of racial and ethnic minority groups, and one in four workers are immigrants.Work benefits improve health outcomes and protect clients of DCWs from healthcare-associated infections by allowing DCWs to take paid sick leave when ill. Portable benefits are benefits employees can take from job to job, prorated so that multiple employers can contribute, and accessible to all workers. Portable benefits are not widely available. I held 1)individual in-depth interviews and focus groups to explore the needs, attitudes, and beliefs of DCWs regarding work benefits, 2) two co-design sessions and a member checking session with DCWs to develop and refine policy recommendations for Maryland DCWs' portable work benefits, and 3) a co-design session and member checking sessions to develop usability recommendations for websites delivering portable benefits to DCWs. This study provides findings about direct care workers' experiences with inadequate or nonexistent work benefits, their recommendations for policy to support benefits that meet their needs and preferences, and their usability recommendations for portable benefits websites. This study provides information on how to design work benefits for DCWs that protect them, protect those around them, and improve work conditions in hopes of improving work conditions and compensation.
The Critical Race Framework Study: Standardizing Critical Evaluation for Research Studies That Use Racial Taxonomy
(2024) Williams, Christopher M.; Fryer, Craig S.; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Introduction: Race is one of the most common variables in public health surveillance and research. Yet, studies involving racial measures show poor conceptual clarity and inconsistent operational definitions. There does not exist a bias tool in the public health literature for structured qualitative evaluation in critical areas of critical appraisal – reliability, validity, internal validity, and external validity – for studies that use racial taxonomy. This study developed the Critical Race (CR) Framework to address a major gap in the literature. Methods: The study involved three iterative phases to answer five research questions (RQs). Phase I was a pilot study of the CR Framework among public health faculty and doctoral students to assess measures of fit (RQ1) and to identify areas of improvement in training, instrumentation, and study design (RQ2). Study participants received training and performed a single article evaluation. Phase II was a national cross-sectional study of public health experts to assess perceptions of the revised training and tool to assess measures of fit (RQ1), to determine the influence of demographic and research factors on perceptions (RQ3), and to gather validity evidence on constructs (RQ4). In Phase III, three raters performed article evaluations to support reliability evidence (RQ4) and to determine the quality of health disparities and behavioral health research studies against the CR Framework (RQ5). Analysis: We assessed the reliability of study results and the CR Framework using non-differentiation analysis, thematic analysis, missingness analysis, user data, measures of internal consistency for adopted instruments, interrater agreement, and interrater reliability. Validity was assessed using content validity (CVI and k*), construct validity, and exploratory factor analyses (EFA). Results: The study recruited 30 highly skilled public health experts across its three phases as part of the final analytic sample. Phase I had poor reliability in which the results could not be confidently interpreted (RQ1) and indicated needed improvement in study design, training, and instrumentation (RQ2). Based on Phase II results, we met or exceeded acceptable thresholds for measures of fit – acceptability, appropriateness, feasibility, and satisfaction (RQ1). Demographic or research factors were not associated with responses (RQ3). Interrater agreement was moderate to high among rater pairs (RQ4). Due to lack of confidence in significance testing, interrater reliability results were inconclusive. Overall data results showed excellent content validity. Based on EFA results, construct validity for reliability and validity items was poor to fair (RQ4). Data results were inconclusive on internal validity and external validity. The twenty studies used in critical appraisal showed low quality or no discussion when the Critical Race Framework was used (RQ5). Discussion: The CR Framework study developed a tool and training with quality evidence for implementation effectiveness, content validity, and interrater reliability to fill a major gap in the public health literature. It contributed an innovative theory-based tool and training to the literature. Future research should seek to study individual perceptions and practices that influence outcomes of CR Framework application and to reduce barriers to ensure that minimum sample sizes can be met for additional testing.
Exploring Young Bi+ Women's Intersecting Mental Health and Sexual and Reproductive Health Experiences in Context: A Multi-Analytic Method Qualitative Study
(2023) Robinson, Jennifer Lynn; Aparicio, Elizabeth M; Butler, James; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Young bi+ women report worse mental health and sexual and reproductive health (SRH) outcomes compared to gay, lesbian, and straight young adults. They experience intersecting threats to their health and well-being due to their sexuality, gender, and stage of development. There is a lack of research on bi+ women’s unique mental health and SRH experiences, and often bi+ women are overlooked due to bi-erasure and biphobia. Regressive policies related to LGBTQ+ and women’s rights, including increased restrictions to reproductive healthcare after the Dobbs v. Jackson Women’s Health Organization decision overturning abortion protections, further threaten bisexual women’s health. This dissertation used a multi-analytic method qualitative approach to explore the intersecting mental health and SRH experiences of young bisexual women in the current socio-political context. Semi-structured in-depth interviews were conducted over Zoom with 16 young bi+ women from across the U.S. A narrative inquiry approach was used to explore young bi+ women’s mental health experiences and coping strategies. In addition, thematic analysis was used to investigate how young bi+ women describe their mental health as intersecting with their SRH in the current socio-political context. The study yielded rich and nuanced information about challenges these young bi+ women experienced throughout their lives that affected their mental health and SRH. Experiencing trauma had far-reaching negative effects on their mental health. Participants discussed the challenges of forming their identity within the social context, particularly as bi+ women in a society that often invalidates bisexual identities and subjugates women. They also discussed the joys along with difficulties of navigating young adulthood. They further described coping with challenges in a variety of adaptive (e.g., therapy, exercise) and maladaptive (e.g., substance use, self-injury) ways. They discussed relying on social support such as partners, friends, family, therapists, and teachers. Participants desired more support with sexuality-related issues, particularly in early adolescence. These bi+ women described their mental health and SRH as intertwined and discussed how bodily autonomy and agency were essential to their well-being. The socio-political context, including social norms, rhetoric, and federal- and state-level policies, influenced participants’ well-being. The current study shows that young bi+ women face unique threats to their mental health and SRH. Practice implications include improving access to affordable and LGBTQ+-affirming healthcare and developing interventions attuned to the needs of young bi+ women. Policies are needed that uphold the choice and agency of young women in their reproductive health decision-making. Future research should continue to explore the needs and experiences of young bi+ women concerning their mental health and SRH including demographic differences along with potential mechanisms resulting in poorer health.
A NATIONAL SURVEY EVALUATING FACTORS INFLUENCING AMERICANS’ WILLINGNESS TO USE AND UPTAKE OF EMERGENCY CONTRACEPTIVE PILLS
(2022) Jasczynski, Michelle; Aparicio, Elizabeth M; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
In the United States, a paradox exists around the issue of contraception; there are more highly effective contraceptive methods available than ever before, including emergency contraception, yet unintended pregnancies have increased in the last 2 decades. Currently, 1 in 2 pregnancies in the United States are unplanned. These disparities are not equitably distributed among women of reproductive age and people who can become pregnant; the burden disproportionately falls upon those with limited access to healthcare, people of color, gender and sexual minorities, those with lower socioeconomic status, and people living in the South. Recognizing the multiple factors driving decisions made about contraception, evaluation of the underutilization and other potential barriers to emergency contraceptive pills (ECP) can be in part addressed by the completion of a national survey. Most of the existing survey data for the United States provide insight into the perceptions of pharmacists, healthcare providers in emergency rooms, and college-aged women. A survey capturing the needs and experiences of a wider range of Americans has not yet been developed—most notably the need for a survey that is inclusive of an expansive understanding of gender identity and sexual orientation to evaluate what, if any, differences exist in how members of these groups view and choose to use ECPs. A web survey was completed in March 2022. Two groups of participants were recruited simultaneously: a group of cisgender, heterosexual women (n = 351), and a group of cisgender sexual minority women and gender minorities assigned female at birth (n = 408), for a total of 759 participants. Comparisons between cisgender heterosexual participants and cisgender sexual minority participants were completed using chi-squared tests and t tests to determine if there were differences in willingness to use and uptake of ECPs by sexual orientation. Latent class analysis (LCA) was completed to identify subgroups among the respondents. The latent class model was then used to determine if membership in the three latent classes predicted willingness to use ECPs and the number of times ECPs were used. Differences between classes on these two outcomes of interest were compared using chi-squared tests. Among each group, approximately 1 in 3 respondents had used ECPs at least once. Cisgender sexual minority participants had a higher willingness to use ECPs when compared to cisgender heterosexual participants (F[2, 708] = 16.33, p < .001). Cisgender sexual minority participants who used ECPs previously also were found to be less willing to reuse ECPs again when compared to their cisgender, heterosexual counterparts (χ2 [2] = 5.14, p = .023), with the most common reason of not wanting to use ECPs again due to participants indicating they would desire to be pregnant. The LCA final model had three classes: high reproductive coercion/low stigma (Class 1), low reproductive coercion/low stigma (Class 2), and low reproductive coercion/high stigma (Class 3). When regressed on the number of times ECPs were used, the three-class model was found to be statistically significant for the overall model (χ2 = 28.95, p < .001). Class 3 (low reproductive coercion, high stigma) was significantly different from Class 1 and Class 2 when comparing the mean number of times ECPs had been used, with members of Class 3 averaging using ECPs 1.56 times versus Class 1 and Class 2 both averaging .56 times use (p < .001). The high levels in which sexual minority women were willing to use ECPs but were less likely to reuse them again should be explored more in depth to understand underlying factors in decision making around contraceptive uptake and pregnancy intentions. The desire to become pregnant is the most common reason given for why sexual minority women would not use ECPs, highlighting the need for healthcare providers to have regular conversations with their patients about sexual behavior, contraceptive use, and pregnancy intentions. Individuals experiencing higher levels of stigma toward their use of ECPs have a higher prevalence of use. Although the direction of this association is yet to be determined, further investigation of this phenomenon can inform practice and policy to understand the impact of stigma and promote reproductive justice.
STATE-LEVEL STRUCTURAL RACISM AND ALCOHOL AND TOBACCO USE BEHAVIORS IN A NATIONAL PROBABILITY SAMPLE OF AFRICAN AMERICANS
(2023) Woodard, Nathaniel; Knott, Cheryl L; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Structural racism is how society maintains and promotes racial discrimination through established and interconnected systems. Structural racism is a historical driver of health disparities, including those in the area of cancer. One pathway posited for this effect is through the promotion of maladaptive coping behaviors, such as alcohol and tobacco use. This dissertation empirically assessed the association between state-level structural racism and alcohol and tobacco use behaviors among African Americans, including within various subgroups of African Americans based on age, gender, and household income. This project analyzed secondary self-report data collected from a national probability sample of 1,946 African Americans in the Religion and Health in African Americans (RHIAA) Study. Existing measures of state level structural racism were merged into the RHIAA dataset including a composite index of structural racism assessed using five dimensions (i.e., residential segregation, and economic, employment, education, and incarceration disparities). Analyses were performed in SPSS Version 28 using hierarchical linear and logistic regression models. In the first study, two models (Model A and Model B) were constructed for each of four outcomes, frequency of alcohol consumption (measured in days per month), frequency of binge drinking (measured in the number of occurrences per month), smoking status (current smoker or not a current smoker), and smoking frequency (never smoked, former smoker, currently smoke on some days, and currently smoke every day). Model A used the composite structural racism index measure to model the four alcohol and tobacco use measures and Model B analyzed the disaggregated dimensions of structural racism rather than the composite measure. All hierarchical analyses controlled for confounding variables (i.e., participant gender, age, education, income, and employment status). In the second study, analyses using the dimension-level approach in Model B from study one were repeated in subgroups stratified by participant age, gender, and income for the frequency of binge drinking and smoking status behaviors. Statistical comparisons of the slope estimates between corresponding subgroups (e.g., younger and older age) were used to test the moderation effects of age, gender, and income on the association between structural racism and alcohol and tobacco use behaviors. Results from these studies generally indicated a positive association between state level structural racism, especially in the incarceration dimension, and binge drinking and tobacco use behaviors. Stratified analyses generally did not support age, gender, or income as moderating variables of the association between structural racism and binge drinking and tobacco use behaviors. Current findings demonstrate a need for further research on structural racism and health and progress in structural racism measurement, including further emphasis of dimension-level measurement and analysis. Findings from the current dissertation highlight the importance of addressing structural racism, especially in incarceration, to reduce alcohol and tobacco use behaviors among African Americans and help address existing health disparities.
EXAMINING THE IMPACT OF PRECONCEPTION AND EARLY PREGNANCY SERUM LEVELS OF MATERNAL VITAMIN D ON CLINICAL MARKERS OF IMPLANTATION AND PREECLAMPSIA
(2023) Alkhalaf, Zeina; Thoma, Marie; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Vitamin D is a hormone rather than a vitamin, that is essential for overall health and wellbeing, including but not limited to the reproductive system. Although vitamin D is available through several sources, such as natural ultraviolet sunlight, food, and supplements, low circulating 25-hydroxyvitamin D (25(OH)D) levels of <30 ng/mL are common among pregnant women, with up to 69% of the US population suffering from the condition. Epidemiologic studies have suggested that low maternal serum 25(OH)D levels may be associated with adverse pregnancy outcomes, such as early pregnancy loss and preeclampsia, which may be initiated early in the pregnancy process during implantation and placentation. From a life course perspective, the periconception and early pregnancy period marks a critical time for establishing a healthy pregnancy. Implantation and placentation occur early in pregnancy and involve a complex process that relies on optimal endometrial receptivity and a host of hormonal and immunologic signaling events. Disruptions to this process may be indicated by early clinical markers of pregnancy complications (e.g., vaginal bleeding or subchorionic hemorrhage) and associated with later adverse outcomes (e.g., preeclampsia). In contrast, higher Human Chorionic Gonadotropin (hCG) levels, which have been linked to nausea and vomiting, may be markers of robust implantation and placentation. Therefore, I sought to investigate the preconception and early gestation maternal serum 25(OH)D levels on: (i) vaginal bleeding and subchorionic hemorrhage; (ii) nausea and vomiting; (iii) preeclampsia. In Aim 1, an analysis of medical record documentation of vaginal bleeding and subchorionic hemorrhage found that women who were persistently deficient/insufficient in maternal serum 25(OH)D at both preconception and 8-week gestation had 2.18 times higher (95% CI: 1.13, 4.20) odds of having subchorionic hemorrhage compared to women who remained sufficient across both time periods, even after adjustment for potential confounders. Additionally, an analysis of daily diaries showed women with deficient 25(OH)D levels had a higher odds (OR: 3.02, 95% CI: 1.13, 8.13) of moderate/heavy bleeding versus none compared to women with sufficient 25(OH)D levels based on self-reported daily diaries on vaginal bleeding at the start of pregnancy. In Aim 2, women with persistently deficient 25(OH)D levels at both preconception and early gestation had lower odds (OR: 0.34, 95% CI: 0.20, 0.60) of experiencing nausea and vomiting based on medical records. In comparison, women who increased their 25(OH)D levels early in pregnancy (i.e., were deficient/insufficient at preconception then became sufficient at 8-week gestation) had 1.71 (95% CI: 1.12, 2.61) times higher odds of nausea and vomiting compared to those who were persistently sufficient across both time periods. Based on self-reported nausea and vomiting symptoms from daily diaries, deficient 25(O)D was associated with lower odds (OR 0.65; 95% CI 0.40, 1.06) of both nausea and vomiting when comparing to sufficient 25(OH)D levels. In Aim 3, women who had deficient 25(OH)D at preconception had an increased risk (RR: 1.45, 95% CI: 0.64, 3.29) of preeclampsia (as identified from medical records), although results were insignificant. Linear spline models demonstrated that the risk of preeclampsia declined with each 1 ng/mL increase of 25(OH)D levels up to 40-45 ng/mL (RR: 0.97, 95% CI: (0.93, 1.00), but that levels beyond this threshold show an increase in the risk of preeclampsia for each 1 ng/mL increase in 25(OH)D (RR: 1.03; 95% CI: 1.00, 1.06). This research highlights the importance of exploring the maternal serum levels of 25(OH)D at both preconception and early gestation and how it may affect adverse pregnancy outcomes, such as vaginal bleeding, subchorionic hemorrhage, preeclampsia, and pregnancy outcomes that signify a robust implantation response, such as nausea and or vomiting. It further underscores the importance of assessing maternal serum 25(OH)D levels prior to critical time of implantation and placentation and potential biologic mechanisms that may lead to adverse pregnancy outcomes. Supporting healthy implantation and placentation is of utmost importance as this may guide the remainder of the health of the pregnancy, and any disruption to this process may increase the mother and infant’s risk of maternal morbidity and mortality (e.g., preeclampsia, vaginal bleeding, subchorionic hemorrhage). Future studies are needed with more diverse, larger sample sizes, and both paternal and maternal nutrition to further assess preconception nutritional risk factors on adverse and robust pregnancy outcomes. Accordingly, this research is vital as it may aid in identifying early factors that may reduce adverse maternal and infant health outcomes.
ADAPTING A BREAST CANCER CONTROL INTERVENTION FOR AFRICAN AMERICAN WOMEN BELOW SCREENING AGE: A CO-DESIGN APPROACH
(2023) Huq, Maisha R; Knott, Cheryl L; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Background: Despite African American women below screening age facing greater mortality from early onset breast cancer relative to similar aged peers of other races/ethnicities and African American women of screening age, little attention is given to this group of younger women. Evidence-based breast cancer educational interventions do not exist for this group of younger women. The purpose of the current work was to address the gap of evidence-based breast cancer educational interventions for African American women below screening age. Aims: The current study had two aims. Aim 1 was to adapt an evidence-based breast cancer educational intervention for African American women of screening age, to be targeted to younger African American women (i.e. those below screening age) using a systematic process guided by the seven-step adaptation framework by Card and colleagues, documented using an established implementation science model, the Framework for Reporting Adaptations and Modifications Enhanced Model (FRAME), and using a virtual co-design approach. Aim 2 was to assess the appropriateness of the adapted intervention for African American women below screening age through online surveys administered at the conclusion of Community Chat sessions. Methods: The adaptation process was guided by Card and colleagues’ seven-step framework. Five virtual co-design sessions with n=15 potential users and key stakeholders were conducted in step 7. Observational notes and FRAME Form data were collected from the co-design sessions and analyzed using five-step thematic and descriptive statistics analyses, respectively. Appropriateness data was collected through an online survey; quantitative data were analyzed using descriptive statistics and open-text survey responses were analyzed using five-step thematic analysis. Results: Application of Card and colleagues’ seven step framework was described. Six themes emerged from observing virtual co-design sessions: technological tools can encourage equal participation; personal relationships and stories enhance design; participants introduced content to promote equity; context of original intervention critical to adapt; challenges to virtual designing; and need for facilitator during co-design. Documentation of the adaptation process guided by FRAME found 14 adaptations led to “Black and Breasted (B&B)”, an Instagram and beauty brand partnership-based breast health education tool prototype. Motivations for adaptations were to promote fit (100%), reach (71%), and equity (29%). Adaptations were content (63%) and context-related (37%). All participants rated B&B as highly appropriate—selecting an average of 4.5 (SD=1.4) and 1.2 (SD=.75) reasons, respectively, B&B would and would not be a good fit. Thematic analysis of open-text responses on how to further enhance B&B identified four themes: increase strategies to improve health equity, use multiple social media, consider non-beauty brands, revise visuals/messages. Conclusions & Implications: While usage of the implementation science models led to a highly appropriate adapted intervention, initial testing identified the need for further strategies to improve equity of health outcomes through the intervention. Findings indicate implementation science frameworks may benefit from centering equity more. Co-design may also be an apt approach to promote health equity in public health interventions.
Exploring the Politics and Radical Health Activism Strategies of Black-Led Grassroots Organizations in Washington, D.C.
(2023) Fox, Imani; Simon-Rusinowitz, Lori; White, Kellee; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Black communities in Washington, DC have long experienced health inequities due to a history of inequitable social policies and inadequate access to health-related resources (Jackson, 2017). Critical, academic scholars and social justice activists implicate the political economy and racial oppression as a root cause of health inequities in the country. Black grassroots organizations demonstrate a history of political and social resistance to oppressive health and social systems, defending their right to health and autonomy, known as radical health activism (Nelson, 2011). Despite rich accounts of Black-led health interventions, their contributions to public health practice and frameworks have not been widely reviewed in public health discourse. Using informant interviews and descriptive study analysis, the health politics and subsequent health intervention strategies of Black grassroots organizations in Washington, D.C were examined. The 3 core themes that emerged from this study were health politics, radical health intervention strategies, and successes and challenges.
"Alexa, do I have an STD?": An Exploration of Young Adult Information Seeking Behaviors When Engaging With Home Assistant Devices About Sexually Transmitted Infections
(2023) Siddiqui, Junaed Ahmad; Baur, Cynthia; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
BACKGROUND: Sexually transmitted diseases and infections continue to disproportionately affect young adults in the United States, with half of all new STIs annually occurring in young adults between the ages of 15 and 24. Advances in digital technologies have allowed for the facilitation of fast and discreet information about sexual health but remains understudied in the context of newer technologies. There is limited research on the effectiveness of Home Assistant Devices as channels to facilitate the information seeking process in young adults. To address this gap, this study explored whether Home Assistant Devices can facilitate the sexual health information seeking process in young adults between the ages of 18 and 26 who already use the internet to search for health information. The purpose of this dissertation was to explore the perspectives of young adults to understand the depth of their sexual health information needs and whether a user-centric designed HAD can be a suitable alternative for fulfilling those information needs. METHODS: Informed by the Theory of Motivated Information Management and Technology Acceptance Model, this qualitative study used the Design Thinking framework to understand young adults’ information needs and created a prototype voice skill to address that need. In-depth interviews were conducted virtually on Google Meet or Zoom and were recorded. This qualitative study occurred in three phases: in the first phase, 10 young adults were interviewed about their information seeking needs, current gaps, and how they thought Home Assistant Devices could fill that need. Insights from those interviews were then analyzed and used to create a prototype that would address sexual health information needs. The prototype was then tested with a new group of ten young adults, and their reactions to the prototype was recorded via interviews. In the third phase, the prototype was refined based on feedback from the previous group, and then re-tested with a new group of 10 young adults. In total, in depth interviews were conducted virtually with 30 young adults to understand information needs and create a prototype voice skill that could serve to facilitate the transfer of sexual health information in a convenient and relevant manner. Inductive thematic analysis was conducted to identify emergent themes. RESULTS: Overall, the sample (n=30) was 63% female, 43% White, with 53% having completed a bachelor’s degree, and 47% having owned a Home Assistant Device for over 12 months. The average age of the sample was 24 years old. After analyzing interviews through inductive thematic analysis in NVivo, four themes that were noted in the first phase as it related to Home Assistant Devices and information needs: the use of HADs as a means of convenience, preferring to use screen-based devices for research, tradeoffs between privacy and functionality, and the ability to emergency triage users for medical attention based on symptoms. Three main themes emerged in the second phase after reacting to the first version of the prototype, including anxiety and frustration when experiencing the unknown, pre-existing positive perceptions of Home Assistant Devices, and negative perceptions of Home Assistant Devices. In the third phase, two main themes emerged: a desire to share visuals to build comfort and bridge the information gap, and an ambivalence towards privacy. DISCUSSION: Privacy concerns remain prominent with Home Assistant Devices when engaging with them for information seeking purposes. These concerns are sometimes met with ambivalence by young adults, who were willing to trade some of their privacy for added features or functionality that could improve their user experience. Furthermore, challenges remain with voice search and screen-based devices are perceived to be easier to use. Lastly, the sexual health information seeking process is sensitive, and many young adults in this sample expressed wanting to have a more personalized experience that acknowledged their specific situations. To the author’s knowledge, this is the first study that explored the factors contributing to the sexual health information seeking process using Home Assistant Devices among young adults between the ages of 18 and 26. The results of this study have several implications for public health practice and research, especially as it relates to the Design Thinking approach for public health voice skill development, as well as addressing a new approach to providing sexual health information to young adults that may be more discreet and relevant to them. The findings from this study contribute to the emerging literature base on the use of Home Assistant Devices to address sensitive health information seeking behaviors.
Maternal and Neonatal Health Intervention Coverage and Measurement in Urban Kenya
(2023) St-Onge Ahmad, Sacha Marie; Howard, Donna E; Stoebenau, Kirsten M; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
High coverage of recommended maternal and neonatal health (MNH) interventions can reduce neonatal mortality in low- and middle-income countries. In Kenya, however, despite overall gains in MNH intervention coverage and neonatal survival, progress in urban areas has slowed. The neonatal mortality rate in Nairobi is 24% higher than rural areas, reversing a longstanding urban advantage in MNH. This multiple method dissertation draws on both quantitative and qualitative data to examine the role of five MNH interventions in explaining this urban disadvantage—health facility delivery (HFD), skilled birth attendance (SBA), early postnatal care (ePNC), skilled postnatal care (sPNC), and early breastfeeding initiation (eBFI). First, using data on mother-child pairs from the Kenya Demographic and Health Survey (KDHS) (n=1,058) this dissertation examines intra-urban variation in coverage, as high urban mortality rates may be explained by differences in coverage in rapidly expanding and impoverished urban informal settlements (IS) as compared to formal settlements (FS). Urban places of residence were operationalized using household- and neighborhood-level characteristics to differentiate informal settlements from formal ones. IS were defined as KDHS clusters where >50% of households lacked >=2 of 4 planned community features (access to improved water and sanitation, durable housing materials, and sufficient living area). Urban categories included: IS in cities, IS in towns, and FS in cities and towns. No differences were observed between settlement type and coverage of any intervention except ePNC. Neonates in IS in towns were less likely to receive ePNC compared to those in FS, suggesting that quality-adjusted measures of intervention coverage might offer evidence of intra-urban variation. Second, using semi-structured qualitative interviews with mothers (n=20) and providers (n=12) in two IS, this dissertation addresses concerns with the measurement of these five interventions within household-based surveys. Specifically, it explores the potential influence of social desirability bias and comprehension of questions and key terms on the validity of mothers’ responses to survey questions that capture coverage. Data were analyzed using template and thematic analysis. Most mothers (1) associate payment with private facilities, (2) generalize the term “hospital” to other facility types, (3) generalize the terms “doctor” and “nurse” to other facility-based employees, (4) determine provider cadre based on role, uniform color, and gender, (5) understand the meaning of ‘assisting with delivery’ and ‘postnatal care check’ as intended, (6) report the timing of a range of postnatal checks, and (7) did not provide concrete descriptions of how they identify time to initiation of breastfeeding or first postnatal check. Women in these communities might: (1) indicate they delivered at a private facility to appear to be wealthier than their peers, (2) indicate they had a SBA if their true attendant was a TBA, and (3) over-report breastfeeding. Findings from this dissertation suggest that the urban disadvantage in neonatal mortality may not be explained by differences in intervention coverage within growing IS communities and may be more complex. Poor quality of facility-based care and low validity of data measuring intervention coverage in household surveys may partly explain these findings. Linking household surveys with facility-based data, using quality-adjusted measures to examine intra-urban variation in coverage, and further exploring of the role of desirability bias and comprehension in survey data across diverse settings is recommended moving forward.
SOCIAL NETWORK INFLUENCE ON INFANT FEEDING DECISIONS AMONG LATINX WOMEN
(2023) Channell Doig, Amara J; Aparicio, Elizabeth M; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Nutrition during the first 1000 days of life is critical for lifelong physical and mental health. Infant milk choices, introduction of complementary foods, and responsive feeding methods can contribute to risk for infection, chronic disease, mental health, and later nutrition and dietary practices. Current feeding interventions are likely to focus on the mother’s decision-making and frequently neglect to explore the impact of the people around her. Little is known about how social networks can influence feeding decisions and how this may impact the acceptance of recommendations from health professionals or intervention content. This dissertation used a convergent mixed methods approach to explore how social networks influence infant feeding decisions and practices for Latinx women in the U.S. In the quantitative portion, 30 participants completed egocentric network mapping to explore network structure and tie strength. In the qualitative portion, 15 of the participants completed in-depth interviews to allow for a better understanding of the influence that network members have, as well as mothers’ decision-making processes. The quantitative and qualitative strands were integrated to allow for a deeper understanding of the social context in which feeding decisions are made. Three manuscripts are presented in the dissertation. The first explores infant feeding support networks and other social influences, including culture and maternal intuition. The participants tended to have small networks and different levels of cultural influence depending on immigration status. The second manuscript examined the influence of information about infant feeding from personal communication compared to online channels. Participants valued the information from medical providers or their support networks and although many used the internet, they had concerns about the information found there. The third manuscript looked at the experiences of the participants who were formula-feeding during the 2022 formula shortage. Although the participants fought to breastfeed their children, they needed to switch to formula to protect their physical and mental health and be there for them. The formula shortage added stress and took an emotional toll on the participants. The dissertation results confirm the importance of social networks as sources of information and support for Latinx mothers with infants during the first year of life. Overall, there was a need for additional support during this time and additional barriers to infant feeding for immigrant mothers. Direct practice implications include how interventions can be developed to provide support. Policy implications include the need to improve structural support for infant feeding, including access to lactation care and food. Future research should continue to assess network support and could look at sociodemographic differences.
ASSESSING HEALTH CARE USE, COSTS, AND QUALITY FOR CENTERS OF EXCELLENCE FOR PEDIATRIC CONGENITAL HEART DISEASE CARE FOR THE MILITARY BENEFICIARY POPULATION
(2022) El-Amin, Amber Jovan; Franzini, Luisa; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Background: For the military beneficiary population with cardiac or congenital anomalies, the Fiscal Year 2019 health care costs were $83 million, including $55 million for newborns who were less than one year of age and $28 million for youth ages 1 to 17 (Kennell and Associates Inc., 2020). The 2019 Military Health System (MHS) costs were approximately $50 billion (Mendez, 2019) and are expected to increase significantly through 2028 (Congressional Budget Office, 2014). In an attempt to close the gap between cost and benefit for its 9.6 million beneficiaries, the MHS has considered targeted inclusion of Centers of Excellence (CoE) for purchased care within TRICARE insurance coverage and MHS policies. In general, a CoE produces consistent outstanding measurable outcomes for a specific medical condition. A Congenital Heart Defect (CHD) is the presence of abnormalities in the heart structure that develop in the uterus during pregnancy. CHDs are the most common types of birth defects and the principal cause of illness and death for birth defect conditions. CHDs are associated with comorbidities and repeat surgical interventions resulting in significant use of health care services during infancy, childhood, and adulthood, making CHDs a great candidate for CoE use.Objective: To compare health care use, costs, and quality of care for pediatric CHD care at CoEs and non-CoEs for the military beneficiary population. Data Sources: Retrospective claims data from the MHS Data Repository for MHS beneficiaries aged 0 to 17 years who received CHD care from 2016 to 2020. Study Design: Using an instrumental variable approach to estimate the impact of CoE use on clinical outcomes (annual admissions, annual emergency room use, and mortality) and health care costs (total costs and hospitalization costs) for pediatric CHD care within the military beneficiary population. Results: A total of 10,865 patients were included, of which 82.9% used a CoE at some point for CHD care. Results suggested that racial disparities in CoE use were not significant for CHD care for the military beneficiary population. There were disparities noted in CoE use by military rank, suggesting that Senior Enlisted and Other ranks were associated with lower odds of CoE use than Junior Enlisted ranks. Results of the IV approach proved that the causal effect of CoE use was a lower probability (-14.1) of emergency room use post one-year CHD diagnosis for the military beneficiary population (p<0.01). The causal effect of CoE use on annual admissions and mortality was insignificant at the .05 significance level but proved that CoE use did not increase annual admissions nor jeopardize patients’ survival post one-year CHD diagnosis for the military beneficiary population. The causal effect of CoE use on CHD related annual costs was a $40,898 decrease in annual costs (p=.059). Although the relationship was not significant at the .05 level, the magnitude of the reduction was approximately 53% of the mean annual cost. When stratified by complexity of CHD diagnosis, the causal effect of CoE use on CHD related annual costs was a statistically significant reduction of $84,852 in annual costs post one-year CHD diagnosis for patients diagnosed with a moderate-complex or single ventricle CHD diagnosis, equating to an approximate 76% reduction in mean annual costs. The causal effect of CoE use on CHD related hospitalization costs was a $33,170 decrease in hospitalization costs (p=.087). Although the relationship was not significant at the .05 level, the magnitude of the reduction was approximately 47% of the mean hospitalization costs. When stratified by CHD diagnosis complexity, the causal effect of CoE use on CHD related hospitalization costs was a statistically significant reduction of $73,084 in hospitalization costs post one-year CHD diagnosis for patients diagnosed with a moderate-complex or single ventricle CHD, equating to an approximate 76% reduction in the mean admission costs. Conclusions: Patients with more severe CHD diagnoses were more likely to use CoEs. After adjusting for selection bias due to disease severity, CoE use improved clinical outcomes, reduced health care resource utilization, and reduced costs for CHD care for the military beneficiary population.
DEVELOPMENT OF A CORE OUTCOME SET FOR STUDIES INVESTIGATING SAFETY, EFFICACY, AND IMPLEMENTATION OF COVID-19 VACCINES: A COLLABORATION WITH AFRICAN AMERICAN/BLACK COMMUNITIES IN BALTIMORE CITY, MARYLAND
(2022) Datar, Reva; Howard, Donna; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Background: Since it was declared a global pandemic in March 2020, Coronavirus Disease 2019 (COVID-19) has claimed over one million lives in the United States. Since COVID-19 vaccine rollout efforts began in Baltimore City, Maryland in December 2020, approximately 63.4% of all residents have been fully vaccinated (i.e., received their first and second doses in a two-dose series or received a single-dose vaccine). Despite efforts to implement equitable vaccine distribution in Baltimore City, prominent disparities in COVID-19 vaccine uptake persist, with poorer, predominantly Black neighborhoods frequently reporting lower levels of vaccine uptake than affluent, predominantly White neighborhoods. Guided by key principles of community-based participatory research, this dissertation explores community experiences with COVID-19 vaccines and develops a core outcome set (COS), inclusive of community-important outcomes, for use in studies evaluating the safety, efficacy, and implementation of COVID-19 vaccines. Methods: In March 2022, semi-structured interviews were held with vaccinated and unvaccinated Black residents of a community in Baltimore City reporting 40% vaccination uptake. Data were analyzed using inductive thematic analysis with subsequent subgroup analyses and thematic network analyses. To assess the extent to which outcomes measured in COVID-19 vaccine studies published between December 2019 and March 2022 aligned with factors of vaccine hesitancy, a systematic literature review (SLR) was conducted. Results from the qualitative analyses and the SLR informed the development of a candidate list of outcomes used in the first round of a Delphi study held in June 2020. After two rounds of Delphi survey distribution, a face-to-face consensus meeting was held with community members and community health workers to prioritize outcomes of interest to all relevant stakeholders and finalize the COS.Results: Thematic analysis yielded four emergent themes relating to COVID-19 vaccine uptake decision making: (I) Safety and efficacy of vaccines, (II) Perceived importance of COVID-19 vaccines in relation to pre-existing community needs, divided into two subthemes, a) Environmental injustice and (b) Personal health concerns, (III) Access to trustworthy, understandable information, and (IV) Physical access to vaccines. Participants acknowledged that physical access to COVID-19 vaccines was not a major barrier to uptake, however finding trustworthy and understandable information about the safety and efficacy of the vaccines were common areas of concern. Of all primary outcomes (N=20) identified in the 56 articles included in the SLR, 85% (n=17) corresponded with factors of vaccine hesitancy. The final COS included 19 outcomes across four “domains:” “Is the vaccine safe?”; “Does the vaccine work in my body?”; “Does the vaccine work in the community?”; and “Outcomes identified during consensus meeting.” Conclusion: The findings from this dissertation suggest that although community-important outcomes related to safety and efficacy of vaccines are often addressed in clinical studies, outcomes measuring institutional trust, economic and health impacts, community acceptance of the vaccines, and trustworthiness of vaccine information are underutilized in studies of vaccine implementation. As these social factors function as barriers to vaccine uptake, particularly among underserved communities, they should be regarded as indicators of equitable access to COVID-19 vaccines. The findings from this dissertation provide a framework with which public health researchers can begin to rethink measures of equity in vaccine rollout efforts.
A NATIONAL SURVEY EVALUATING FACTORS INFLUENCING AMERICANS’ WILLINGNESS TO USE AND UPTAKE OF EMERGENCY CONTRACEPTIVE PILLS
(2022) Jasczynski, Michelle Laurin; Aparicio, Elizabeth M; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
In the United States, a paradox exists around the issue of contraception; there are more highly effective contraceptive methods available than ever before, including emergency contraception, yet unintended pregnancies have increased in the last 2 decades. Currently, 1 in 2 pregnancies in the United States are unplanned. These disparities are not equitably distributed among women of reproductive age and people who can become pregnant; the burden disproportionately falls upon those with limited access to healthcare, people of color, gender and sexual minorities, those with lower socioeconomic status, and people living in the South. Recognizing the multiple factors driving decisions made about contraception, evaluation of the underutilization and other potential barriers to emergency contraceptive pills (ECP) can be in part addressed by the completion of a national survey. Most of the existing survey data for the United States provide insight into the perceptions of pharmacists, health care providers in emergency rooms, and college-aged women. A survey capturing the needs and experiences of a wider range of Americans has not yet been developed—most notably the need for a survey that is inclusive of an expansive understanding of gender identity and sexual orientation to evaluate what, if any, differences exist in how members of these groups view and choose to use ECPs.A web survey was completed in March 2022. Two groups of participants were recruited simultaneously: a group of cisgender, heterosexual women (n = 351), and a group of cisgender sexual minority women and gender minorities assigned female at birth (n = 408), for a total of 759 participants. Comparisons between cisgender heterosexual participants and cisgender sexual minority participants were completed using chi-squared tests and t tests to determine if there were differences in willingness to use and uptake of ECPs by sexual orientation. Latent class analysis (LCA) was completed to identify subgroups among the respondents. The latent class model was then used to determine if membership in the three latent classes predicted willingness to use ECPs and the number of times ECPs were used. Differences between classes on these two outcomes of interest were compared using chi-squared tests. Among each group, approximately 1 in 3 respondents had used ECPs at least once. Cisgender sexual minority participants had a higher willingness to use ECPs when compared to cisgender heterosexual participants (F[2, 708] = 16.33, p < .001). Cisgender sexual minority participants who used ECPs previously also were found to be less willing to reuse ECPs again when compared to their cisgender, heterosexual counterparts (χ2 [2] = 5.14, p = .023), with the most common reason of not wanting to use ECPs again due to participants indicating they would desire to be pregnant. The LCA final model had three classes: high reproductive coercion/low stigma (Class 1), low reproductive coercion/low stigma (Class 2), and low reproductive coercion/high stigma (Class 3). When regressed on the number of times ECPs were used, the three-class model was found to be statistically significant for the overall model (χ2 = 28.95, p < .001). Class 3 (low reproductive coercion, high stigma) was significantly different from Class 1 and Class 2 when comparing the mean number of times ECPs had been used, with members of Class 3 averaging using ECPs 1.56 times versus Class 1 and Class 2 both averaging .56 times use (p < .001). The high levels in which sexual minority women were willing to use ECPs but were less likely to reuse them again should be explored more in depth to understand underlying factors in decision making around contraceptive uptake and pregnancy intentions. The desire to become pregnant is the most common reason given for why sexual minority women would not use ECPs, highlighting the need for healthcare providers to have regular conversations with their patients about sexual behavior, contraceptive use, and pregnancy intentions. Individuals experiencing higher levels of stigma toward their use of ECPs have a higher prevalence of use. Although the direction of this association is yet to be determined, further investigation of this phenomenon can inform practice and policy to understand the impact of stigma and promote reproductive justice.
Meditation, Flow, and Heavy Social Alcohol Use among College Students
(1992) Francis, Timothy Lewis; Iso-Ahola, Seppo; Recreation; Digital Repository at the University of Maryland; University of Maryland (College Park, Md)
The basis for this study was an experiment designed to explore the effectiveness of various meditation practices and choice and combination of such, regardless of focus, in achieving more drug-free flow experiences, longer periods of meditation adherence, and decreases in heavy social alcohol use among college students. The study also examined the hypothesis that higher frequencies of reported flow in meditation were associated with lower levels of reported alcohol use and higher frequencies of post-training meditation practice, regardless of meditation focus. The interaction of several critical intervening variables not comprehensively addressed in previous studies on meditation and substance abuse, including experimental expectancy and demand, previous alcohol use, hypnotic susceptibility, and personality was checked and controlled for in this experiment. After receiving basic meditation training, 53 subjects with drinking rates typical of heavy social alcohol users were randomly assigned to one of four meditation groups or to a control group. Three groups practiced only one of three foci--object focused, visualization, or mindfulness. The fourth group chose their meditation foci each day from any of the above three types. The fifth (control) group practiced an attention Placebo activity. Four weeks of daily diaries following meditation were used to determine the level of the dependent variables--frequency of flow and amount of alcohol use. Subjects then reported post-required meditation frequency and alcohol use through four weekly phone interviews. MANOVA, ANOVA, and zero-order correlations were employed to analyze the relationships between the variables. No one specific meditation focus nor having choice and combination of foci, was indicated to result in significantly more flow, less alcohol use, or longer mediation adherence. There was a slight indication that higher frequencies of flow were related to higher frequencies of meditation practice, but no indication that more flow was related to less alcohol use. These results should be interpreted with caution for several reasons, including the short meditation training and practice period, low reliability and validity of subject reports, and problems associated with large variations in drinking rates. Future research on these issues should refine training and testing methods so that better treatment methods can be found.
AN INTERSECTIONALITY, MINORITY STRESS, AND LIFE-COURSE THEORY INFORMED LATENT PROFILE ANALYSIS OF STRESS(OR) AND PSYCHOSOCIAL BUFFERING FACTORS AMONG FIRST-GENERATION LATINX IMMIGRANT YOUTH FROM THE NORTHERN TRIANGLE: EFFECTS ON MENTAL HEALTH AND SUICIDALITY
(2022) Salerno, John P.; Boekeloo, Bradley O; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
In alignment with the intersectionality theoretical framework, first-generation Latinx immigrant youth from the Northern Triangle (i.e., El Salvador, Guatemala, and Honduras) may suffer from complex forms of vulnerability as a result of their multiple marginalized social identities and statuses. Indeed, consistent with the life-course perspective, immigrant youth from the Northern Triangle face unique risks for experiencing cumulative external stressors across the life-course in the context of the phases of migration, including pre- to post-migration victimization, and immigration-related family separation (e.g., forced family separation). The minority stress theory adds the potential for experiencing immigrant minority identity/status-related stress, such as discrimination or negative feelings attributed to being an immigrant, specifically during the post-migration context in the U.S., which could exacerbate mental health by adding to cumulative stress. Yet, the post-migration time period may be an important turning point for Latinx immigrant youth from the Northern Triangle, during which psychosocial buffering resources, like school, peer, and family support, and ethnic identity importance may have a strong and distinct impact that could significantly mitigate the cumulative mental health effects of life-course and minority stress(ors). Considering the increasing surge of immigrant youth from the Northern Triangle, which account for the majority of youth being apprehended at the U.S.-Mexico border, as well as grave concerns about their experiences of vulnerability and mental health, it is of utmost importance to utilize intersectionality, minority stress, and life-course theories to identify and understand the psychosocial risk and protective factors that can mitigate or exacerbate their mental health during post-migration in the U.S. To this end, in collaboration with a community-partner and a high school in Hyattsville, Maryland, primary surveys assessing external life-course stressors across the phases of migration (i.e., pre- to post-migration victimization, and family separation), post-migration immigrant-related minority stress (i.e., immigrant-related discrimination and negative immigrant stress-related feelings), and post-migration psychosocial buffering factors (i.e., family, peer, and school support, and ethnic identity importance) among first-generation Latinx immigrant youth from the Northern Triangle were administered (N = 172). In Paper 1, the aim was to identify potential intersections of minority stress (post-migration immigrant minority stress) and psychosocial buffering resources (family, peer, and school support, and ethnic identity importance), and their associations with external stressors (pre- to post-migration victimization and immigration-related family separation). Latent profile analysis was conducted to identify and describe latent profiles that varied at the intersections of post-migration immigrant minority stress and psychosocial buffering factors, and their associations with pre- to post- migration victimization, and family separation stressors. In Paper 2, the aim was to understand whether latent profiles characterized by the intersections of immigrant minority stress and psychosocial buffering factors, and external stressors (pre- to post-migration victimization and immigration-related family separation) jointly predicted mental health outcomes. ANOVA models were conducted to examine the associations of latent profile membership, pre- to post-migration victimization, and family separation with mental health outcomes (i.e., PTSD, depression, anxiety, and emotional problem symptoms) when all were included in the model as independent predictors. In Paper 3, the aim was to understand whether latent profile membership and external stressors jointly predicted suicidality. Logistic regression models were conducted to examine the associations of latent profile membership, pre- to post-migration victimization, and family separation with suicidality (i.e., suicidal ideation) when all were included in the model as independent predictors. Paper 1 findings revealed a three latent-profile model characterized by post-migration 1) moderate immigrant minority stress and low psychosocial buffering factors (moderate stress/low buffer), 2) moderate immigrant minority stress and moderate psychosocial buffering factors (moderate stress/moderate buffer), and 3) low immigrant minority stress and high psychosocial buffering factors (low stress/high buffer). Post-migration victimization was significantly associated with latent profile membership, such that those in the low stress/high buffer profile group (11%) were least likely to experience post-migration victimization compared to the moderate stress/moderate buffer (most likely; 49%) and moderate stress/low buffer (33%) profile groups (p < .001). Overall prevalence of in-transit victimization (7.70%) was too low for valid statistical assessment. Pre-migration victimization and family separation were not significantly associated with latent profile membership. Paper 2 factorial ANOVA analyses demonstrated that latent profile membership post-migration victimization, and family separation were statistically significant predictors of mental health outcomes (PTSD, depression, anxiety, and emotional problem symptoms) when all were included in the models. Bonferroni-corrected factorial ANOVA test findings revealed that youth in the low stress/high buffer profile group were significantly less likely to experience PTSD (p < .001, p = .003), depression (p < .001, p < .001), anxiety (p < .001, p < .001), and emotional problem symptoms (p = .002, p = .041) compared to youth in both the moderate stress/moderate buffer and moderate stress/low buffer profile groups (respectively). The moderate stress/low buffer profile group did not differ significantly from the moderate stress/moderate buffer profile group in-terms of any mental health outcome. Post-migration victimization was independently and positively associated with PTSD (p = .010), anxiety (p < .001), and emotional problem (p = .042) symptoms (but not depression symptoms), and forced family separation was independently and positively associated with PTSD (p = .026), anxiety (p = .017), and depression symptoms (p = .009; but not emotional problem symptoms) in factorial ANOVA. Pre-migration victimization was not a significant predictor of any mental health outcomes, and in-transit victimization prevalence was too low for valid statistical assessment of its association with mental health outcomes. Paper 3 multivariable logistic regression analyses demonstrated that latent profile membership was the only statistically significant predictor of suicidality. The low stress/high buffer profile group was significantly less likely to experience suicidality compared to both the moderate stress/moderate buffer (87.8% decrease in the odds; OR = 0.122; p < .001) and moderate stress/low buffer (95.6% decrease in the odds; OR = 0.044; p < .001) profile groups in multivariable logistic regression. The moderate stress/low buffer profile group did not differ significantly from the moderate stress/moderate buffer profile group in-terms of suicidality. Post-migration victimization was no longer a statistically significant predictor of suicidality in the multivariable logistic regression model. Pre-migration victimization and family separation were not significant predictors of suicidality, and in-transit victimization prevalence was too low for valid statistical assessment of its association with suicidality. Considering the results of all three studies in Papers 1-3, latent profiles, characterized by the intersections of immigrant minority stress and psychosocial buffering resources, were a significant independent predictor of all mental health outcomes and suicidality. Yet, external stressors, particularly post-migration victimization (PTSD, anxiety, and emotional problem symptoms) and immigration-related family separation (PTSD, anxiety, and depression symptoms) were also significant independent predictors of mental health outcomes, suggesting that these factors also explain post-migration mental health outcomes to some degree above and beyond latent profile membership. In totality, findings strongly suggest that further exploration of post-migration immigrant minority stress and psychosocial buffering resources is urgently warranted to identify ways of overcoming the effects of externalized immigrant-related stressors and reducing mental health burden among first-generation Latinx immigrant youth from the Northern Triangle, a highly vulnerable population. Consistent with minority stress and intersectionality theories, protective associations with mental health were present when post-migration immigrant minority stress was low and psychosocial buffering was high, but these protective associations were lost when immigrant minority stress increased to moderate level and when psychosocial buffering decreased to moderate or low level. From another viewpoint, there were risk associations with mental health when post-migration immigrant minority stress was moderate and psychosocial buffering was low or moderate, but these risk associations were reversed toward being protective when immigrant minority stress lowered to low level and when psychosocial buffering increased to high level. That post-migration victimization and forced family separation remained positive predictors of mental health outcomes in multivariable analyses highlights that these external life-course stressors exacerbated mental health above and beyond the associations of post-migration immigrant minority stress and psychosocial buffering latent profile membership alone. Findings provide valuable information for policy and intervention development and reform in the U.S. that focuses on factors that can be intervened on during the post-migration phase in the U.S. (as opposed to less intervenable factors that occurred during pre and in-transit migration) to positively impact mental health and wellbeing among first-generation Latinx immigrant youth from the Northern Triangle. When immigrant youth experience low immigrant minority stress, strong peer and family support networks, as well as supportive schools and feeling that their foreign, cultural, and ethnic identities are celebrated and welcomed, this could have a significant protective effect toward their mental health and suicidality. However, if youth are facing low levels of these psychosocial buffering experiences and moderate (or potentially high) levels of immigrant minority stress, they may experience negative effects that hinder their mental health and suicidality. Additionally, post-migration victimization and forced family separation are particularly impactful predictors of mental health above and beyond the effects of latent profile group membership alone, which indicate the urgent need for mental health services and support resources that address these stressful and traumatic life-course experiences among first-generation Latinx immigrant youth from the Northern Triangle. Findings elucidate post-migration immigrant minority stress and psychosocial buffering pathways for future development and evaluation to improve Northern Triangle immigrant youths’ mental health and suicidality.
UNDERSTANDING CHANGES IN CONTRACEPTIVE INTENTION, KNOWLEDGE, AND ATTITUDES IN THE CONTEXT OF THE DELCAN INITIATIVE TO REDUCE UNINTENDED PREGNANCY
(2022) Skracic, Izidora; Steinberg, Julia R; Lewin, Amy B; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Unintended pregnancies are consistently linked to a higher risk of negative health, social, and economic outcomes for both mother and child. A Delaware public health initiative sought to expand statewide access to all contraceptive methods, particularly IUDs and implants (also known as long-acting reversible contraception (LARC)), due to their high effectiveness, upfront costs, and provision barriers. This study examined changes in self-reported planned contraceptive use, knowledge, and attitudes prior to and following a visit with a medical provider to better understand the provider role in contraceptive outcomes. A diverse group of women (N=474) were recruited at primary care and women’s health Title-X-funded clinics in Delaware. Pre-visit contraceptive use or plan was assessed with two measures: current method use and a composite of current method use and planned method use. Incorporating women’s contraceptive plans in the pre-visit measure resulted in fewer participants being categorized as switching to LARC (2.3%) after a provider visit, compared to the measure that only accounted for current contraceptive use (8.2%). The strongest predictor of changing to a method of higher effectiveness was pre-visit contraceptive choice. On average, women’s knowledge increased; participants with lower pre-visit knowledge were more likely to improve in knowledge post-visit (p<0.001). On average, positive attitudes about LARC decreased, although some individual items changed in the positive direction while others changed in the negative direction. Those with more versus less positive attitudes before the clinic visit had larger decreases in positive attitudes (p<0.001). The full rollout of the DelCAN initiative was associated with an increase in LARC knowledge, while its association with change in LARC attitudes and effectiveness level of planned method use was mixed. These findings suggest that measuring contraceptive plans as opposed to only current method use before a visit is important when applying a pre-post visit design to evaluations of contraceptive use or plans; broadening the conceptualization and measurement of pre-visit contraceptive use or plans could better capture the sources of change that may manifest in post-visit. Additionally, clinic visits may serve as effective education events, particularly for women with lower contraceptive knowledge, and they may provide a more realistic understanding of different contraceptive methods’ advantages and disadvantages. It is possible that the lack of increase in positive contraceptive attitudes may be attributable to the negativity bias following changes in knowledge and personal experience, but more research is needed to replicate and understand the phenomenon.
Multilevel Factor Influence on Alternative Tobacco Product Use Among U.S. Foreign-Born Residents
(2022) Roh, Esther Jungmee; Fryer, Craig S; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Background: In the United States, the use of alternative tobacco products (ATPs), such as e-cigarettes, cigars, little cigars, hookah, or smokeless tobacco, has been rising even as conventional cigarette smoking continues decreasing. Broadly speaking, smoking behaviors are influenced by multiple factors at the intrapersonal, interpersonal, organizational, and community levels, including individual harm perceptions toward ATPs, peer and family use of tobacco products, ATP marketing and promotions targeted at specific races and ethnicities and acculturation. However, data on ATP use among U.S. foreign-born residents are limited and factors influencing ATP use among this population are not yet well understood. The primary purpose of this dissertation was to understand multilevel factors, addressed in Social Ecological Model (SEM), that influence ATP use among U.S. foreign-born residents. Purpose: The aim of study one was to assess the association between acculturation, harm perceptions, and peer and family use of tobacco products, and ATP use among U.S. foreign-born residents using waves 3 and 4 of the Population Assessment of Tobacco and Health (PATH) Study. The aim of study two was to assess the association between acculturation, peer and family use of ATPs and exposure to ATP advertisements, marketing and promotions, and ATP use among U.S. foreign-born residents using the same dataset. The aim of study three was to obtain a deeper understanding of how multilevel factors influence ATP use among non-U.S. citizen Korean residents. Methods: In studies one and two, quantitative data analyses were conducted from 2,507 foreign-born adult residents using PATH waves 3 and 4. Chi-square test and multivariate logistic regressions were used, and moderation and mediation analyses were conducted. In study three, twenty-one non-U.S. citizen Korean residents who currently or formerly smoked or used any ATPs and were aged 18-39 years in District of Columbia (DC), Maryland (MD) or Virginia (VA) completed 60-minute semi-structured in-depth interviews. Interviews were transcribed verbatim, coded, and analyzed thematically. Findings: In study one, findings suggest that certain acculturation factors predicted current and lifetime ATP use among U.S. foreign-born residents. For example, less acculturated foreign-born residents in the U.S. perceived ATPs as very or extremely harmful to their health and were less likely to use ATPs compared to the U.S.-born counterparts. In study two, findings indicated that less acculturated foreign-born residents were less likely to have peer and family who use ATPs and to be exposed to ATP advertisements, marketing and promotions compared to the U.S.-born counterparts. In study three, e-cigarettes were the most popular ATPs with participants, followed by hookahs and heated tobacco products (specifically IQOS). Participants showed more ambivalence or regarded e-cigarettes and hookahs as less harmful than conventional cigarettes. Additionally, smoking initiation was influenced mainly by peers who smoked. Conclusion: Multiple factors at different determinant levels influence tobacco product use behaviors among U.S. foreign-born residents. Acculturation factors, along with harm perceptions, peer and family influence, and ATP advertisements, marketing, and promotions exposure, seem to influence ATP use among U.S. foreign-born residents. Implications: This research calls for culturally tailored interventions and smoking cessations for U.S. foreign-born residents. Future research should investigate multiple tobacco product use among foreign-born residents as well as how the country of origin influences ATP use behaviors.
ASSESSING UNDERGRADUATE STUDENTS’ JUDGEMENT OF SEXUAL ACTIVITY CONSENT SEEKING AND COERCIVE BEHAVIORS, AND ATTITUDE TOWARD ESTABLISHING SEXUAL CONSENT
(2022) Abebe, Israel; Howard, Donna; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Sexual violence continues to be a serious public health problem, particularly among the college student population. This dissertation developed and implemented a web-based factorial vignette experiment to investigate vignette- and respondent-level factors that can explain undergraduate students’ evaluation of consent-seeking and verbal coercion in hypothetical vignette scenarios (N=420; Study 1). The vignettes embedded three factors with two levels each: level of intoxication (2 levels – sober/drunk), type of sexual relationship (2 levels – casual/committed), and, place of sexual encounter (2 levels – sexual initiator’s/partner’s residence). The respondent-level factors included gender identity, history of sexual victimization, attitude toward establishing consent, and endorsement of alcohol-involved consent scripts. Mixed models were used to assess the effects of vignette-level and respondent-level factors on students’ evaluations of consent-seeking and verbally coercive behaviors. The results showed significant differences in students’ evaluation of whether consent was sought based on level of intoxication, type of relationship, vignette scenarios, gender, consent attitude and endorsement of consent scripts. In addition, the study found significant differences in evaluations of coercive behaviors based on the vignette scenarios, consent attitude and acceptance of consent scripts. The dissertation also assessed the relationship between students’ endorsement of alcohol-involved sexual consent scripts and attitude toward establishing sexual consent, after accounting for covariates (Study 2). Hierarchical regression was used for this purpose. The study demonstrated that there is an inverse relationship between endorsement of consent scripts and consent attitude, after controlling for gender identity, relationship status, and campus athletic participation. There were also significant differences in consent attitude based on gender and relationship status. The findings from this dissertation emphasize the importance unpacking the elements of sexual consent definitions provided in many campus policies and understanding the cognitive and contextual factors that influence students’ interpretations of those elements. In addition, the findings support that there are broader issues such as acceptance of scripts that influence students’ consent attitudes. The implications include the need to target contextually relevant predictors of consent understanding and consent attitude in campus sexual violence prevention efforts.
WHAT HAPPENS WHEN STUDENTS KNUCK AND BUCK SYSTEMS OF INJUSTICE? A MULTIMETHOD STUDY EXPLORING THE RELATIONSHIP BETWEEN STUDENT ACTIVISM AND EMOTIONAL WELL-BEING
(2022) Smith, Samantha Alyce; Arria, Amelia M; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
In recent years, college students' declining mental health status has garnered the attention of public health and educational professionals. Mental health is a complex construct influenced by biological, behavioral, social, and environmental factors. One critical dimension of mental health is emotional well-being, representing the positive and negative emotions one experiences. Little research exists regarding the relationship between activism, a possible social influence, and mental health. This multimethod dissertation study focuses on the relationship between college student participation in activism and contemporary social movements, including the Black Lives Matter movement, and different dimensions of emotional well-being, including depressive and anxiety symptoms, level of optimism, and sense of belonging. Framed by the Transactional Theory of Stress and Coping, the qualitative portion of the research involved in-depth interviews among 18 students aged 18-25 who participated in 2020 Black Lives Matter protests. The purpose of these interviews was to examine the short-term impact of protest participation on student emotional well-being and how activism was related to coping. Findings revealed that the sociopolitical climate negatively impacted student emotional well-being, and those associated negative emotions acted as a motivator to participate in protests. Conversely, participating in protests garnered sense of belonging and empowerment. Protest participation appeared to serve as an emotion-focused coping strategy among these students. The quantitative analyses conducted in this dissertation utilized secondary data from the 2019 Wake Forest Well-being Assessment to investigate the motivators (Aim 2) and emotional well-being correlates (Aim 3) of activism participation. For both analyses, two forms of activism were studied – disruptive (e.g., protests) and persuasive tactics (e.g., digital activism). Civic morals identity centrality and discrimination were examined as possible motivators. Multivariate and multinomial logistic regression models developed for Aim 2 held constant other potential confounding variables (i.e., gender, sexual orientation, parental education and race/ethnicity) and revealed positive associations between discrimination experiences and civic moral identity centrality and disruptive activism (p<.001) and persuasive tactics (p<.001). Regression models for Aim 3 that examined the relationship between activism participation and emotional well-being revealed that disruptive activism tactics were positively associated with depressive symptoms (p<.001), anxiety symptoms (p<.001), and sense of belonging (p<.05). A negative association was observed between disruptive activism and optimism (p<.05). All of these associations were robust to the inclusion of demographic covariates. Coping did not appear to moderate any of the relationships observed. Taken together these finding begin to elucidate the nuanced and complex relationship between activism and emotional well-being. Given that a significant proportion of college students studied participated in some form of activism, our understanding of the impact of activism on student emotional well-being is an important area that warrants additional investigation in future studies. The findings of this study can be used to support ongoing intervention development that addresses the mental health needs of college students, specifically those engaged in activism work. Additionally, these findings can be used to support mitigating health disparities that are the result from sociopolitical factors such as racism and discrimination.
