To determine whether there is any correlation between sudden decrease in barometric pressure and onset of labor, a non-experimental, retrospective study at a 948-bed tertiary care hospital was done. Pregnant patients of 36 weeks gestation or more who presented with spontaneous onset of labor during the 48 hours surrounding the 12 occurrences of significant drop in barometric pressure in 1992 were included in the study. Significantly more occurrences of onset of labor were identified in the 24 hours after a drop in barometric pressure than were identified in the 24 hours prior to the drop in barometric pressure (P < 0.05). Therefore, the overall number of labor onsets increased in the 24 hours following a significant drop in barometric pressure.
为了确定气压的突然下降与分娩开始之间是否存在任何关联，在一家拥有948张床位的三级护理医院进行了一项非实验性回顾性研究。该研究纳入了孕周36周及以上、在1992年12次气压显著下降的48小时内自然分娩的孕妇。与气压下降前的24小时相比，气压下降后的24小时内分娩开始的次数显著更多（P<0.05）。因此，在气压显著下降后的24小时内，分娩开始的总数有所增加。
