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.
先前的研究表明，身体活动（PA）与睡眠的数量和质量有关。但关于其方向性问题以及这些关系是否因年龄、性别和种族而有所不同仍存在疑问。我们在一周内检查了 PA 和睡眠之间的每日双向关联。参与者为来自 MIDUS 生物标志物研究的 427 名成年人，平均年龄为 54.21±11.67（61%为女性，30%为非白人）。使用 ActiWatch 64 测量 PA（总活动）和睡眠（总睡眠时间；TST 和睡眠后觉醒时间；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 增加的一天之后，年轻和非白人参与者的 TST 明显缩短。PA 较高的日子也与年轻参与者的 WASO 减少有关。双向效应也出现了；在 TST 较短的一夜之后，男性而不是女性第二天的 PA 活动减少。与其他关于每日 PA 和睡眠的研究一样，效应大小较小。未来的研究应评估可能解释这些人口统计学差异的潜在机制。
