There are grounds for the hypothesis that poor sleep quality, regardless of the pre-gestational nutritional status, is a risk factor for inadequate gestational weight gain.
To investigate the association between sleep quality and insufficient or excessive gestational weight gain in Brazilian pregnant women without gestational complications and monitored in public prenatal care units.
This is a cross-sectional study nested within a cohort study that reviewed pregnant women's mental health, sleep, and nutritional outcome. Data collection was carried out from May 2018 to June 2019 through face-to-face and telephone interviews and consultation of pregnant women's medical records. Sleep quality was assessed using the Mini-sleep Questionnaire. The pregnancy weight gain was measured based on the Institute of Medicine's recommendations. Univariate and multivariate Poisson regression analysis was used for the two outcomes: insufficient or excessive weight gain, using pregnant women with adequate weight gain as the reference category. Associations were considered significant when p < 0.05.
The prevalence of severe sleep disorders was high: 63.4% of pregnant women experienced this condition. Severe sleep disorders enhanced independently the risk of insufficient gestational weight gain (PR = 2.40; 95% CI = 1.06-5.42, p = 0.035). There was no association between sleep disorders and excessive gestational weight gain.
The hypothesis that poor sleep quality influences gestational weight gain was confirmed. Severe sleep disorders, a highly prevalent condition, significantly increased the prevalence of insufficient gestational weight gain, yet it was not associated with excessive weight gain. Thus, educational actions should be included in the preconception and prenatal periods, in order to encourage the adoption of habits that favor sleep quality, an intervention that may have positive effects in reducing insufficient gestational weight gain.
无论孕前营养状况如何，睡眠质量差都有可能成为妊娠体重增加不足的风险因素，这一假说具有一定的依据。
调查在没有妊娠并发症且在公共产前保健单位接受监测的巴西孕妇中，睡眠质量与妊娠体重不足或过度增加之间的关系。
这是一项嵌套在队列研究中的横断面研究，该研究回顾了孕妇的心理健康、睡眠和营养状况。数据收集工作于 2018 年 5 月至 2019 年 6 月期间通过面对面和电话访谈以及查阅孕妇的医疗记录进行。采用迷你睡眠问卷评估睡眠质量。根据医学研究所的建议，将妊娠增重作为测量指标。使用体重增加充足的孕妇作为参考类别，对两种结果（体重不足或过度增加）进行单变量和多变量泊松回归分析。当 p 值<0.05 时，认为关联具有统计学意义。
严重睡眠障碍的患病率较高：63.4%的孕妇存在这种情况。严重的睡眠障碍独立增加了妊娠体重不足的风险（PR=2.40；95%CI=1.06-5.42，p=0.035）。睡眠障碍与妊娠体重过度增加之间无关联。
睡眠质量影响妊娠体重增加的假设得到了证实。严重睡眠障碍是一种高发疾病，它显著增加了妊娠体重不足的发生率，但与体重过度增加无关。因此，应在孕前和孕期阶段采取教育措施，鼓励养成有利于睡眠质量的习惯，这种干预措施可能对减少妊娠体重不足有积极影响。
