孕妇睡眠不足和体重过度增加与孕产妇结局有关。然而，目前还不清楚它们对孕妇的相互影响。这项队列研究旨在确定睡眠质量的轨迹及其与妊娠期体重过度增加的关系。403名孕妇的数据收集在三个访问点：早期妊娠，10至17周之间，中期妊娠，18至21周之间，和晚期妊娠：28-32周的怀孕。采用匹兹堡睡眠质量指数（Pittsburgh Sleep Quality Index）评估睡眠质量。半参数混合模型被用来估计整个怀孕期间的睡眠质量模式。两个轨迹分别被确定为从好到差组（76.42%）和恒定差组（23.57%）。据观察，睡眠质量差与两组的妊娠期体重过度增加有关。妊娠晚期睡眠质量差的孕妇妊娠期体重增加过多（校正比值比3.47，95%CI 1.25，9.62）。相比之下，在恒定贫穷组中，即使在妊娠中期也建立了这种关系（调整的比值比3.12，95% CI 1.06，9.19）。这项研究的结果表明，大多数孕妇报告睡眠质量下降，但少数人报告整个怀孕期间睡眠质量稳定较差。睡眠质量差与妊娠期体重过度增加有关。相比之下，那些睡眠质量稳定的孕妇有更大的风险获得过度的妊娠期体重增加。
Poor sleep and excessive weight gain of pregnant women are associated with maternal outcomes. However, it's unknown regarding their effects of each other in pregnant women. This cohort study aimed to identify the trajectories of sleep quality and their associations with excessive gestational weight gain during pregnancy. Data of 403 pregnant women were collected at three visiting points: early pregnancy, between 10 and 17 weeks, mid-pregnancy, between 18 and 21 weeks, and late pregnancy: 28-32 weeks of pregnancy. Sleep quality was examined by the Pittsburgh sleep quality index. A semiparametric mixture model was used to estimate the patterns of sleep quality throughout the pregnancy. Two trajectories were identified as good-to-poor group (76.42%) and constant poor group (23.57%), respectively. It was observed that poor sleep quality was associated with excessive gestational weight gain in both groups. Poor sleep quality during late pregnancy in good-to-poor group predicted excessive gestational weight gain (adjusted Odds Ratio 3.47, 95% CI 1.25, 9.62). In contrast, the relationship was established even at mid-pregnancy in constant poor group (adjusted Odds Ratio 3.12, 95% CI 1.06, 9.19). Results from this study showed that most of pregnant women reported decreased sleep quality, however, a minority reported stable-poor sleep quality throughout pregnancy. Poor sleep quality was associated with excessive gestational weight gain during pregnancy. In comparison, those pregnant women with stable-poor sleep quality had a greater risk to get excessive gestational weight gain.
