Poor sleep in the postpartum is often treated as an unavoidable consequence of childbirth. This study aims to compare objective and subjective measures of sleep, explore the relationship between sleep and postpartum weight retention (PPWR), and investigate factors that may contribute to sleep quality in the postpartum period. In this cross-sectional cohort, PPWR, sleep quality (Pittsburgh Sleep Quality Index (PSQI)), and objective sleep and physical activity (accelerometry) were assessed in 109 women 0–52 weeks postpartum. Anthropometric and demographic data were collected. Gestational weight gain (GWG) was classified as inadequate, appropriate, or excessive according to Institute of Medicine guidelines. Average GWG (33.7 lbs) and PPWR (5.39 lbs) were not different between “good” (PSQI < 6) and “bad” (PSQI ≥ 6) sleepers. Following adjustment, mothers with excessive GWG who were “bad” sleepers had 5.26 higher odds of PPWR ≥ 10 lbs compared with all other combinations of GWG and PSQI. PSQI was not correlated with total sleep time (accelerometer-derived). Light activity and moderate-to-vigorous physical activity (MVPA) were associated with reduced odds of being a “bad” sleeper. The influence of GWG on PPWR was modified by postpartum sleep quality. Both light activity and meeting the MVPA guidelines in the postpartum were associated with higher sleep quality. Novelty Subjectively rated poor sleep may represent the number of awakenings and wake after sleep onset in postpartum women. Poor postpartum sleep quality increases excessive postpartum weight retention in women with excessive GWG. Women doing light-to-vigorous physical activity in the postpartum are less likely to experience poor sleep quality.

睡眠质量对产后体重滞留的影响[J].

产后睡眠不佳通常被视为分娩不可避免的后果。本研究旨在比较睡眠的客观和主观测量，探讨睡眠与产后体重滞留 (PPWR) 之间的关系，并调查可能影响产后睡眠质量的因素。在这个横断面队列中，评估了 109 名产后 0-52 周女性的 PPWR、睡眠质量（匹兹堡睡眠质量指数 (PSQI)）以及客观睡眠和身体活动（加速度计）。收集了人体测量学和人口统计数据。根据医学研究所的指南，妊娠体重增加 (GWG) 被归类为不足、适当或过度。平均 GWG (33.7 lbs) 和 PPWR (5.39 lbs) 在“好”（PSQI < 6）和“坏”（PSQI ≥ 6）枕木之间没有差异。调整后，与 GWG 和 PSQI 的所有其他组合相比，GWG 过多且睡眠“不良”的母亲 PPWR ≥ 10 磅的几率高 5.26。PSQI 与总睡眠时间（加速度计衍生）无关。轻度活动和中度到剧烈的体力活动 (MVPA) 与成为“不良”睡眠者的几率降低有关。GWG对PPWR的影响受产后睡眠质量的影响。产后轻度活动和满足 MVPA 指南都与更高的睡眠质量相关。新颖性 主观评价的睡眠不佳可能代表产后妇女的觉醒次数和入睡后觉醒次数。产后睡眠质量差会增加 GWG 过多女性的产后体重过度滞留。
