Stress and depressive symptoms are associated with maladaptive health behavior practices such as unhealthy eating, sedentary behavior, insufficient sleep, and substance use. The relative and interactive effects of stress and depressive symptoms on health behavior practices are less well understood. The present study examined these processes in a daily diary study of 127 college students. Results from hierarchical generalized linear models indicated that depressive symptoms, and chronic and daily stress, but not acute stressful life events, were significantly associated with a composite score of daily maladaptive health behavior engagement (depressive symptoms b = .01, SE= .00, p < .01; chronic stress, b = .03, SE= .01, p < .01; daily stress, b = .01, SE= .01, p = .02); unexpectedly, the effect of stress on health behaviors was not moderated by depressive symptoms. Additionally, results demonstrated that the effect of depressive symptoms on health behaviors was mediated by fluctuations in daily negative affect. These results bear implications for intervention during a crucial period in the development of mental and physical health.
压力和抑郁症状与不良的健康行为习惯有关，例如不健康的饮食、久坐行为、睡眠不足和物质滥用。压力和抑郁症状对健康行为习惯的相对和交互影响还不太清楚。本研究通过对 127 名大学生的日常日记研究来检验这些过程。分层广义线性模型的结果表明，抑郁症状以及慢性和日常压力与每日不良健康行为的综合得分显著相关（抑郁症状 b=0.01，SE=0.00，p<0.01；慢性压力 b=0.03，SE=0.01，p<0.01；日常压力 b=0.01，SE=0.01，p=0.02）；出乎意料的是，抑郁症状对健康行为的影响不受压力的调节。此外，结果表明，抑郁症状对健康行为的影响是由日常负面情绪波动介导的。这些结果对心理健康和身体健康发展的关键时期的干预具有重要意义。
