Over a 2-year period, 1,516 births were investigated to determine whether the onset of parturition could be correlated with the phases of the moon or to barometric height. 1,269 births started spontaneously, and of these, 254 (20%) started with premature rupture of the fetal membranes (PROM). No association was observed between the phases of the moon and deliveries beginning with PROM or with deliveries beginning without PROM. 1,302 of the women had regular menstrual cycles before pregnancy, and among these no specific relationship was found between the phases of the moon and the first day of the last menstruation before pregnancy. No relationship was found between the frequency of PROM and the barometric height. Variations in barometric height up to 9 h before the fetal membranes ruptured did not influence the frequency of PROM. Deliveries with PROM occurred significantly more often among primipara than among multipara. PROM occurred more frequently during night-time in the 8-hour period between 10 p.m. and 6 a.m. These results suggest that the causes of PROM are not correlated to the phases of the moon or to meteorological variations.
在为期两年的时间里，对1516例分娩进行了调查，以确定分娩的开始是否与月相或气压高度有关。1269例分娩为自然发动，其中254例（20%）以胎膜早破（PROM）开始。未观察到月相与以胎膜早破开始的分娩或未以胎膜早破开始的分娩之间存在关联。1302名女性在怀孕前月经周期规律，在这些女性中，未发现月相与怀孕前最后一次月经第一天之间存在特定关系。未发现胎膜早破的频率与气压高度之间存在关系。胎膜破裂前长达9小时的气压高度变化并未影响胎膜早破的频率。初产妇中发生胎膜早破的分娩明显多于经产妇。胎膜早破在晚上10点至早上6点的8小时夜间时段更频繁发生。这些结果表明，胎膜早破的原因与月相或气象变化无关。
