A Longitudinal Evaluation of Goal-Striving Stress and Sleep Duration Among African Americans in the Jackson Heart Study

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. Mean differences (β [standard error]) between changes in GSS and changes in sleep duration were assessed using linear regression models that adjusted for length of follow-up, sociodemographics, health behaviors/risk factors, and stressors. Results In the fully adjusted models, the increase in GSS from examination 1 to examination 3 was associated with a decrease in sleep duration (in minutes) from examination 1 to examination 3 in the overall cohort (β = −7.72 [2.44], p
