Physical activity is associated with improved sleep quality and duration in the general population, but its effect on sleep in postpartum women is unknown. We examined cross-sectional and longitudinal associations between hours/week of self-reported domain-specific and overall moderate to vigorous physical activity (MVPA) and sleep quality and duration at 3- and 12-months postpartum among a cohort of 530 women in the Pregnancy, Infection, and Nutrition Postpartum Study. MVPA was not associated with sleep quality or duration at 3-months postpartum. At 12-months postpartum, a 1 h/week increase in recreational MVPA was associated with higher odds of good (vs. poor) sleep quality (odds ratio, OR 1.14; 95 % confidence interval, CI, 1.03-1.27) and a 1 h/week increase in child/adult care MVPA was associated with lower odds of good (vs. poor) sleep quality (OR = 0.93; 95 % CI 0.88-0.99). A 1 h/week increase in child/adult care MVPA (OR 1.08, 95 % CI 1.00-1.16) was associated with higher odds of long sleep duration and 1 h/week increases in indoor household (OR 1.09, 95 % CI 1.01-1.18) and overall MVPA (OR 1.04, 95 % CI 1.01-1.07) were associated with higher odds of short (vs. normal) sleep duration. Comparing 3-months postpartum to 12-months postpartum, increased work MVPA was associated with good sleep quality (OR 2.40, 95 % CI 1.12-5.15) and increased indoor household MVPA was associated with short sleep duration (OR 1.85, 95 % CI 1.05-3.27) as measured at 12-months postpartum. Selected domains of MVPA and their longitudinal increases were associated with sleep quality and duration at 12-months postpartum. Additional research is needed to elucidate whether physical activity can improve postpartum sleep.
在普通人群中，身体活动与睡眠质量改善及睡眠时间延长有关，但它对产后女性睡眠的影响尚不清楚。在“孕期、感染与营养产后研究”中的530名女性队列里，我们研究了自我报告的特定领域及总体中度至剧烈身体活动（MVPA）每周小时数与产后3个月和12个月时睡眠质量及睡眠时间之间的横断面和纵向关联。产后3个月时，MVPA与睡眠质量或睡眠时间无关。产后12个月时，娱乐性MVPA每周增加1小时与良好（vs.差）睡眠质量的较高几率相关（优势比，OR 1.14；95%置信区间，CI，1.03 - 1.27），儿童/成人护理MVPA每周增加1小时与良好（vs.差）睡眠质量的较低几率相关（OR = 0.93；95% CI 0.88 - 0.99）。儿童/成人护理MVPA每周增加1小时（OR 1.08，95% CI 1.00 - 1.16）与较长睡眠时间的较高几率相关，室内家庭MVPA每周增加1小时（OR 1.09，95% CI 1.01 - 1.18）和总体MVPA每周增加1小时（OR 1.04，95% CI 1.01 - 1.07）与短（vs.正常）睡眠时间的较高几率相关。将产后3个月与产后12个月进行比较，工作MVPA增加与良好睡眠质量相关（OR 2.40，95% CI 1.12 - 5.15），室内家庭MVPA增加与产后12个月时测量的短睡眠时间相关（OR 1.85，95% CI 1.05 - 3.27）。MVPA的选定领域及其纵向增加与产后12个月时的睡眠质量和睡眠时间相关。需要进一步研究以阐明身体活动是否能改善产后睡眠。
