Item 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.Item Understanding the Risk of Drug Overdose and Alcohol-Induced Deaths Among Adults with Different Types of Disabilities(2023) Aram, Jonathan; Dallal, Cher M; Epidemiology and Biostatistics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Background: Disability is associated with drug and alcohol morbidity and mortality, which have reached high levels in recent years. Previous disability studies often combine all disabilities into a single category or focus on a single type of limitation. This dissertation characterizes different types of disabilities among U.S. adults and assesses associations with drug and alcohol morbidity and mortality. Methods: Using the 2018-2019 National Survey on Drug Use and Health (NSDUH, Aim 1), a nationally representative cross-sectional survey (n=83,485), different individual disabilities and co-occurring disabilities were identified. Multivariable logistic regression was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for associations between disability type and prevalence of drug and alcohol use disorders. Disabilities were also characterized within the Mortality Disparities in American Communities Study (Aims 2 and 3), a nationally-representative prospective cohort with baseline data collected in 2008 and mortality follow-up through 2019 (n=3,324,000). Multivariable Cox proportional hazards regression was used to estimate adjusted hazard ratios (aHRs) and CIs for associations between disability type and drug overdose death (OD, Aim 2) and alcohol-induced death (AID, Aim 3). Results: Within the NSDUH analysis, adults with cognitive disability had increased odds of drug (aOR=3.3; 95% CI=2.9–3.8), and alcohol use disorder (aOR=2.3; 95% CI=2.0–2.6), compared to adults without disability. Positive associations of lesser magnitude were observed between hearing/seeing and ambulatory disabilities and drug use disorder. In MDAC analyses, OD risk was elevated among adults with cognitive (aHR=2.6; 95% CI=2.4–2.9), ambulatory (aHR=2.8; 95% CI=2.6–3.1), ambulatory and hearing/seeing (aHR=2.5; 95% CI=2.0–3.1), and hearing/seeing disability (aHR=1.6; 95% CI=1.4–1.9), compared to adults without disability. The risk of AID was elevated for adults with co-occurring ambulatory and hearing/seeing disability (aHR=1.8; 95% CI=1.5–2.2), ambulatory disability only (aHR=1.5; 95% CI=1.3–1.7), and hearing/seeing disability only (aHR=1.2; 95% CI=1.0–1.4). Conclusions: The examination of specific disability categories reveals unique associations that are not apparent when all disabilities are combined. These findings can be used to improve access to recovery support services. Expansion of educational and occupational opportunities for adults with disabilities should be considered as strategies to reduce drug and alcohol morbidity and mortality.Item THE RELATIONSHIP BETWEEN PSYCHOLOGICAL AGGRESSION VICTIMIZATION AND WOMEN’S ANXIETY: ALCOHOL USE AS A MODERATOR(2018) Mauss, Jasmine Marie; Epstein, Norman B; Family Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Intimate partner aggression is a serious concern, creating problematic issues among individuals and couples in romantic relationships. Psychological aggression, specifically, has shown to have detrimental effects on physical and mental health. Victims of such abuse often times find different ways to cope with the negative feelings that accompany being a recipient of partner aggression. The present study examines psychological aggression in relationships and its resulting associations with female partner anxiety symptoms. Further, the study explores alcohol use as a possible coping strategy and the way this tactic moderates the relationship between partner aggression and anxiety. Results from the study show that there was no significant association between partner aggression and anxiety symptoms and that alcohol use did not act as a moderator for this association. However, it was found that for two subtypes of psychological aggression (domination/intimidation and denigration) there were negative associations between aggression victimization and anxiety. Unlike the other subscales of psychological aggression (hostile withdrawal and restrictive engulfment), which showed no significance, higher levels of domination/intimidation, restrictive engulfment, and denigration were associated with lower levels of anxiety. Implications of the findings for future research and clinical practice are discussed.Item "Promoting Responsible Action in Medical Emergencies": Determining the Impact of a New University of Maryland Alcohol Protocol(2010) Hammamy, Ranwa Diaa; Clark, Pamela; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The purpose of this investigation was to determine the impact of the University of Maryland's "Responsible Action Protocol." Judicial records were evaluated to determine if calls for medical assistance increased after the protocol. Descriptive summaries indicated that the number of calls in the semester following the RAP was double the average of the previous six semesters. While there was no variation in calls prior to the RAP (χ2 = 4.346, p = .501, df = 5), the post-RAP Fall 2009 semester added significant variation (χ22 = 25.069, p < .001, df = 6). Student focus groups were used to evaluate student reaction to the protocol. Students seemed unaware of the RAP's provisions, and stated its language prevented them from trusting the protocol. Students further indicated the university alcohol education was not relevant and did not provide information regarding alcohol poisoning. The findings suggest that the RAP and the university's alcohol education programming will need revisions to increase their impact.Item The influence of parental communication about the negative effects of alcohol on college students' alcohol use(2004-12-08) Boyle, Jennifer Rebecca; Boekeloo, Bradley O; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Many college students experience negative effects of excessive and underage drinking. Parental influences have been found capable of delaying adolescent drinking and reducing riskier adolescent drinking behaviors. However, there has been little investigation regarding the influence of parents on the drinking behaviors of college students while students are at school. A web-based survey was conducted with 265 University of Maryland first-year students who were18-19 years old and living in residence halls. Focus groups (n=12), observed pre-tests and in-depth interviews (n=5), pilot tests (n=4), an alpha test, and expert review (n=5) were conducted to assist in the development of the web-based survey. It was hypothesized that: 1) students who report greater parental communication regarding the negative effects of alcohol are less likely to report problem drinking than students who report less communication, 2) the association between communication and problem drinking is mediated by constructs borrowed from the Theory of Reasoned Action (TRA), 3) the association between communication and problem drinking is mediated by constructs borrowed from the Health Belief Model (HBM), 4) the association between communication and problem drinking is mediated by constructs borrowed from both the TRA and HBM, 5) the association between communication and problem drinking is best explained by the model incorporating constructs from both the TRA and the HBM. Logistic regression was conducted to test the first hypothesis. Path analysis and structural equation modeling were used to test hypotheses two through four. Models were qualitatively compared to test hypothesis five. Results of logistic regression indicated that there was no significant direct relationship between parent-child alcohol communication and problem drinking. Structural equation modeling revealed that the relationship between communication and problem drinking was mediated by attitude toward alcohol. Students whose parents talked with them more about the negative effects of alcohol held more favorable attitudes toward alcohol (p = -0.13, p < 0.05). In turn, students holding more favorable attitudes toward alcohol experienced more drinking problems (p = 0.19, p < 0.05). The TRA model was determined to be the model that best explained the relationship between communication and problem drinking. Possible explanations for unexpected findings are discussed.
