A small number of studies have, thus far, evaluated the association between maternal snoring and fetal growth revealing conflicting results. No study has compared fetal growth between women with habitual snoring who snored before pregnancy and women with habitual snoring that started to snore during pregnancy.
To examine the effect of maternal snoring on fetal outcome and to investigate the differences between "chronic snorers" and "new-onset snorers".
Women of singleton, uncomplicated, full-term pregnancies completed a questionnaire. Obstetric and labor records were reviewed. Newborn records were reviewed for gestational age, birth weight, Apgar score and gender.
246 low risk women were studied. Mean BMI at the beginning of pregnancy was 22.3 ± 3.5 kg/m(2). 32% reported habitual snoring. Of those, 26% were chronic snorers and 74% were new-onset snorers. Neither significant difference in fetal growth was found between snorers and non-snorers nor between chronic snorers and new-onset snorers. Increased rate of nulliparous women was found in new-onset snorers compared with both chronic snorers and non-snorers (54 vs. 25 and 29% respectively; p = 0.001).
In pregnant women with no apparent risk factors, maternal snoring does not affect fetal growth. No differences in maternal characteristics or fetal outcome were found between chronic snorers and new-onset snorers.
迄今为止，少数研究评估了孕妇打鼾与胎儿生长之间的关联，结果相互矛盾。尚无研究比较孕前就习惯性打鼾的女性与孕期开始习惯性打鼾的女性之间的胎儿生长情况。
研究孕妇打鼾对胎儿结局的影响，并调查“慢性打鼾者”与“新发打鼾者”之间的差异。
单胎、无并发症、足月妊娠的女性填写一份问卷。回顾产科和分娩记录。查看新生儿记录，了解胎龄、出生体重、阿氏评分和性别。
对246名低风险女性进行了研究。妊娠开始时的平均体重指数为22.3±3.5kg/m²。32%的女性报告有习惯性打鼾。其中，26%为慢性打鼾者，74%为新发打鼾者。打鼾者与非打鼾者之间以及慢性打鼾者与新发打鼾者之间在胎儿生长方面均未发现显著差异。与慢性打鼾者和非打鼾者相比，新发打鼾者中初产妇的比例增加（分别为54%对25%和29%；p=0.001）。
在无明显危险因素的孕妇中，孕妇打鼾不影响胎儿生长。慢性打鼾者与新发打鼾者在孕妇特征或胎儿结局方面未发现差异。
