    The Health Implications of Stress among Asian Americans in the US and Chinese In China: the Effects of Perceived Stress and Caregiving Stress on Cardiovascular Risk Factors
    (2018) Lu, Xiaoxiao; Lee, Sunmin; Epidemiology and Biostatistics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Prior research suggests that stress plays a role in the etiology and progression of cardiovascular disease (CVD). To lend a more accurate depiction of the associations between stress and CVD risk factors, this dissertation used a comprehensive approach to conceptualizing stress by assessing two dimensions of stress: perceived stress and caregiving stress. The objective of this dissertation was to investigate the associations between multiple dimensions of stress and the risk factors of CVD. This dissertation also explored the potential mechanisms that underlie the relationships between stress and CVD risk factors. In Paper 1 (Chapter 3), we assessed the associations between perceived stress and hypertension across varying levels of social support and social network among 530 Chinese, Korean and Vietnamese Americans. Results indicated that individuals with high perceived stress were 61% more likely to have hypertension compared to those with low levels of perceived stress (Odds Ratio (OR): 1.61, 95% Confidence interval (CI): 1.15, 2.46). Social support had a direct beneficial effect on hypertension, irrespective of whether individuals were under stress. In Paper 2 (Chapter 4), we used five waves of longitudinal data from the China Health and Nutrition Survey to examine the association between parental caregiving and blood pressure among 2,586 Chinese women. We found that parental caregivers were associated with higher systolic (β-coefficient (β) = 1.16; p ≤ 0.01) and diastolic blood pressure (β = 0.75; p ≤ 0.01) compared with non-caregivers across multiple waves. In Paper 3 (Chapter 5), we investigated the relationship between caregiving trajectory and Metabolic Syndrome (MetS) among 1,636 Chinese women. Three caregiving trajectories were identified by using group-based trajectory analysis. Results showed that ‘rising to high-intense’ caregivers (OR = 1.90; 95% CI: 0.90, 4.00) and ‘stable low-intense’ caregivers (OR = 1.56; 95% CI: 1.06, 2.29) were associated with higher risk of MetS compared with non-caregivers. This dissertation is innovative in its examining the associations of multiple dimensions of stress with CVD risk factors among Asian subgroups. Findings from the proposed study will be used to develop future stress management interventions, and incorporating culturally and linguistically appropriate strategies into community outreach and education to decrease cardiovascular disease risk within the Asian population.

    Aerobic Fitness and Prevalence of the Metabolic Syndrome in African Americans and non-African Americans in PREMIER: a randomized controlled trial
    (2008-08-11) Levin, Laura A; Young, Deborah R; Kinesiology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Background: The Metabolic Syndrome is the clustering of several cardiovascular risk factors for coronary heart disease and Type 2 Diabetes Mellitus. This syndrome is of public health importance due to its high prevalence and high correlation to all-cause, CHD, and CVD mortality. The purpose of the current study was to determine if a change in aerobic fitness in the treatment group significantly decreased the odds of Metabolic Syndrome at 6 and 18 months. Methods: There were 810 adult participants in this trial with above-optimal blood pressure and up to stage I hypertension. Participants were part of an advice-only control group or a treatment group where physical activity increases were the main component. Results: A change in aerobic fitness, independent of treatment status, was significantly associated with a decrease in prevalent Metabolic Syndrome at both 6 and 18 months (OR: 0.96, CI: 0.94 - 0.98 & OR: 0.96; CI: 0.94 - 0.98, respectively).
