Snoring frequently occurs among pregnant women, particularly in the later stages of pregnancy. It often signals obstructive sleep apnea (OSA), which could potentially affect pregnancy outcomes negatively. Hence, our study aimed to investigate how snoring influences the likelihood of pregnancy complications and fetal outcomes in a cohort of expectant mothers.
We enrolled pregnant women in their second and third trimesters and had them fill out a questionnaire concerning sleep-related symptoms such as snoring, excessive daytime sleepiness, and frequency of nighttime awakenings, along with anthropometric measurements. Subsequently, the participants were divided into snorers and non-snorers, and the occurrence of pregnancy complications and fetal outcomes was monitored.
The study enrolled a total of 212 pregnant women, among whom 35 were identified as snorers and 177 as non-snorers during mid to late pregnancy. This indicated a snoring prevalence of 16.5% in our sample. Significant differences were noted between the two groups regarding the occurrence of oligohydramnios (11.43% vs. 2.82%, p = 0.044) and fetal distress (28.57% vs. 8.47%, p = 0.003). Logistic regression analyses revealed that snoring was independently associated with fetal distress (odds ratio [OR] = 4.99, 95% confidence interval [CI] 1.88-13.23, p = 0.001).
Our findings suggest that habitual snoring was the independent risk factor fetal distress after adjusting for potential confounders, indicating that habitual snoring may have a detrimental effect during mid to late pregnancy.
孕妇经常打鼾，尤其是在妊娠晚期。这通常表明存在阻塞性睡眠呼吸暂停（OSA），这可能对妊娠结局产生负面影响。因此，我们的研究旨在调查打鼾如何影响预期母亲队列中妊娠并发症和胎儿结局的可能性。
我们招募了妊娠中期和晚期的孕妇，并让她们填写一份关于睡眠相关症状（如打鼾、白天过度嗜睡和夜间觉醒频率）的问卷，同时进行人体测量。随后，将参与者分为打鼾者和非打鼾者，并监测妊娠并发症和胎儿结局的发生情况。
该研究共纳入了 212 名孕妇，其中 35 名在妊娠中期至晚期被诊断为打鼾者，177 名为非打鼾者。这表明我们的样本中打鼾的患病率为 16.5%。两组在羊水过少（11.43%比 2.82%，p=0.044）和胎儿窘迫（28.57%比 8.47%，p=0.003）的发生方面存在显著差异。Logistic 回归分析显示，打鼾与胎儿窘迫独立相关（比值比[OR] = 4.99，95%置信区间[CI] 1.88-13.23，p=0.001）。
在调整了潜在混杂因素后，我们的研究结果表明，习惯性打鼾是胎儿窘迫的独立危险因素，这表明习惯性打鼾在妊娠中期至晚期可能产生不良影响。
