背景：心理应激对健康相关行为有不良影响，但缺乏纵向研究。研究调查了孩子和母亲感知到的压力是如何与孩子三年的身体活动和久坐行为轨迹联系在一起的。方法：母亲和她们的孩子（N = 186对；基线8-12岁，57%为西班牙裔）在3年内完成了6次评估。儿童和母亲分别使用儿童压力量表和感知压力量表自我报告感知压力。使用加速度计评估儿童的中度至剧烈身体活动（MVPA）和久坐行为。在研究儿童的MVPA和久坐行为时，混合模型考察了母亲和儿童感知压力的相互作用。结果：感知压力×时间流逝的相互作用对儿童MVPA和久坐行为有显著影响（p < 0.05）。母亲感受到的平均压力越大，孩子的MVPA就越低，久坐行为就越多。儿童压力与时间的相互作用对儿童的MVPA有显著影响（P< 0.05），但对久坐行为没有显著影响。儿童较高的平均感知压力与儿童MVPA的较小下降有关。结论：促进儿童身体活动和减少屏幕时间的干预措施可以减轻心理压力对这些行为的影响，特别是对母亲而言。
Background: Psychological stress has adverse effects on health-related behaviors, yet longitudinal research is lacking. Research examined how children’s and mothers’ perceived stress are associated with children’s physical activity and sedentary behavior trajectories across 3 years.Methods: Mothers and their children (N = 186 dyads; 8–12 y at baseline, 57% Hispanic) completed 6 assessments across 3 years. Children and mothers self-reported perceived stress using the Stress in Children Scale and Perceived Stress Scale, respectively. Children’s moderate to vigorous physical activity (MVPA) and sedentary behavior were assessed using accelerometers. Mixed models examined interactions of mothers’ and children’s perceived stress by time elapsed in the study on children’s MVPA and sedentary behavior.Results: The perceived stress × time elapsed interactions were significant for children’s MVPA and sedentary behavior (Ps < .05). Higher average perceived stress in mothers was associated with greater decreases in children’s MVPA and increases in children’s sedentary behavior. The child stress × time elapsed interactions was significant for children’s MVPA (P< .05) but not sedentary behavior. Higher average perceived stress in children was associated with smaller decreases in children’s MVPA.Conclusion: Interventions to promote physical activity and reduce screen time in children should mitigate the effects of psychological stress, especially among mothers, on these behaviors.
