先前的研究表明，体力活动(PA)与睡眠的数量和质量有关。关于方向性以及关系是否因年龄、性别和种族而异的问题仍然存在。我们在一周多的时间里检查了PA和睡眠之间的日常双向联系。参与者是MIDUS Biomarker研究的427名成年人，平均年龄为54.21 ± 11.67(61%为女性，30%为非白人)。用活动表测量总活动量(PA)和总睡眠时间(TST)和入睡后觉醒(WASO)。多水平混合效应模型显示，PA和睡眠之间的关系因年龄、种族和性别而异。在PA增加的一天后，年轻和非白人参与者的TST显著缩短。对于较年轻的参与者，PA较高的天数也与较少的WASO相关。双向效应也出现了；在TST较短的一晚之后，男性而不是女性参与第二天的PA较少。像其他关于日常PA和睡眠的研究一样，影响的规模很小。未来的研究应该评估可以解释这些人口统计学差异的潜在机制。
Prior work suggests physical activity (PA) is related to quantity and quality of sleep. Questions remain regarding directionality, and whether relationships vary by age, sex, and race. We examined daily bidirectional associations between PA and sleep over one week. Participants were 427 adults from the MIDUS Biomarker study, with a mean age of 54.21 ± 11.67 (61% female, 30% non-white). PA (total activity) and sleep (total sleep time; TST and waking after sleep onset; WASO) were measured with an ActiWatch 64. Multilevel mixed-effects models showed differences in the relationships between PA and sleep by age, race, and sex. Following a day with increased PA, younger and nonwhite participants had significantly shorter TST. Days with higher PA were also associated with less WASO for younger participants. Bidirectional effects also emerged; following a night with shorter TST, men, not women, engaged in less next-day PA. Like other studies of daily PA and sleep, effect sizes were small. Future studies should assess potential mechanisms that could explain these demographic differences.
