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.
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.
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 < .002), in high school graduates (β = -21.23 [5.63], p < .001), and in college graduates (β = -7.57 [3.75], p = .044) but not in those with less than a high school education (β = 1.49 [8.35], p = .86) or those who attended college but did not graduate (β = 0.44 [4.94], p = .93).
Changes in GSS were inversely associated with changes in sleep duration over a mean period of 8 years in AA subgroups. Interventions that reduce stress related to goal striving should be considered to help improve sleep health in AAs.
本研究旨在评估非裔美国人（AAs）的目标奋斗压力（GSS）变化与睡眠时间变化之间的关联，并确定这种关联是否因性别、年龄和/或教育程度而有所不同。
我们使用来自杰克逊心脏研究的检查 1（2000-2004 年，n=5306）和检查 3（2009-2013 年，n=3819）的数据进行了纵向分析，最终样本为 3500 人。通过从检查 3 的 GSS 中减去检查 1 的 GSS 来计算 GSS 和睡眠时间的变化。使用线性回归模型评估 GSS 变化和睡眠时间变化之间的平均差异（β[标准误差]），该模型调整了随访时间、社会人口统计学、健康行为/风险因素和压力源。
在完全调整的模型中，从检查 1 到检查 3 的 GSS 增加与整个队列中从检查 1 到检查 3 的睡眠时间减少（β=-7.72[2.44]，p<.002）、高中毕业生（β=-21.23[5.63]，p<.001）和大学毕业生（β=-7.57[3.75]，p=.044）相关，但与未完成高中学业的人（β=1.49[8.35]，p=.86）或上过大学但未毕业的人（β=0.44[4.94]，p=.93）无关。
在 AAs 的亚组中，GSS 的变化与 8 年的平均睡眠时间变化呈负相关。应考虑采取减少与目标奋斗相关的压力的干预措施，以帮助改善 AAs 的睡眠健康。
