Objective: The purposes of this study were to assess the association between changes in goal-striving stress (GSS) and changes in sleep duration in African Americans (AAs) and to determine if the association varies by sex, age, and/or educational attainment.
Methods: We completed a longitudinal analysis using examination 1 (2000-2004, n = 5306) and examination 3 (2009-2013, n = 3819) data from the Jackson Heart Study, with a final sample of 3500. Changes in GSS and changes in sleep duration were calculated by subtracting examination 1 GSS from examination 3 GSS.
Objective: To examine associations between physical activity (PA), inflammation, coronary artery calcification (CAC), and incident coronary heart disease (CHD) in African Americans.
Methods: Among Jackson Heart Study participants without prevalent CHD at baseline (n=4295), we examined the relationships between PA and high-sensitivity C-reactive protein, the presence of CAC (Agatston score ≥100), and incident CHD. Based on the American Heart Association's Life's Simple 7 metrics, participants were classified as having poor, intermediate, or ideal PA.
Background Goal-striving stress (GSS), the stress from striving for goals, is associated with poor health. Less is known about its association with cardiovascular disease (CVD). Methods and Results We used data from the JHS (Jackson Heart Study), a study of CVD among blacks (21-95 years old) from 2000 to 2015.

For this reason, goal-striving stress (GSS), the difference between aspiration and achievement, weighted by disappointment, may contribute to poor sleep quality and suboptimal sleep duration among AAs.
Methods: We completed a cross-sectional analysis using exam 1 data (2000-2004) from the Jackson Heart Study (JHS) (n=4943).
Background: Limited research has examined the association of life-course socioeconomic status (SES) with hypertension prevalence and incidence in a large cohort of African Americans.
Methods: Among 4,761 participants from the Jackson Heart Study (JHS), we examined the association of SES indicators with prevalent and incident hypertension. We used multivariable Poisson regression to estimate prevalence ratios (PR, 95% confidence interval-CI) of baseline (2000-2004) hypertension by adult (education, income, occupation, wealth) and childhood (mother's education) SES.
