Coitus with or without orgasm in late pregnancy is inconsistently associated with preterm rupture of amniotic sac membranes. We tested the hypothesis that during late pregnancy sexual behaviors including sexual positioning relate to the occurrence of premature rupture of membranes.
Women aged 15 to 45 years having preterm premature rupture of membranes, term premature rupture of membranes, or preterm delivery without premature rupture of membranes were matched singly by age, race, and parity to control women delivered of term infants. Information about six sexual activities, obstetric history, cervical infections, smoking during pregnancy, and sociodemographic information was obtained by face-to-face interview.
Only the male superior position was significantly associated with preterm premature rupture of membranes (odds ratio 2.40, 95% confidence interval 1.16 to 4.97) and preterm delivery without premature rupture of membranes (odds ratio 1.82, confidence interval 1.02 to 3.25) after confounding variables were controlled for. No sexual positioning or sexual activities related significantly to term premature rupture of membranes.
Most sexual positions and activities during late pregnancy are not associated with adverse pregnancy outcomes.
妊娠晚期有无性高潮的性交与羊膜囊早破之间的关联并不一致。我们检验了这样一个假设，即妊娠晚期包括性交体位在内的性行为与胎膜早破的发生有关。
年龄在15至45岁之间发生早产胎膜早破、足月胎膜早破或未发生胎膜早破的早产的女性，按年龄、种族和产次与足月分娩的对照女性进行单因素匹配。通过面对面访谈获取了有关六种性活动、产科病史、宫颈感染、孕期吸烟以及社会人口学信息。
在控制了混杂变量后，只有男上体位与早产胎膜早破（比值比2.40，95%置信区间1.16至4.97）以及未发生胎膜早破的早产（比值比1.82，置信区间1.02至3.25）显著相关。没有性交体位或性活动与足月胎膜早破有显著关联。
妊娠晚期的大多数性交体位和性活动与不良妊娠结局无关。
