. To examine the association between maternal leisure time physical activity and mode of delivery. . Population-based multicentre cohort. From the Danish Dystocia Study, we included 2,435 nulliparous women, who delivered a singleton infant in cephalic presentation at term after spontaneous onset of labor in 2004-2005. We analysed mode of delivery according to self-reported physical activity at four stages, that is, the year before pregnancy and during first, second, and third trimester, in logistic regression models. Further, we combined physical activity measures at all four stages in one variable for a proportional odds model for cumulative logits. . Mode of delivery (emergency caesarean section; vacuum extractor; spontaneous vaginal delivery). . The odds of emergency caesarean section decreased with increasing levels of physical activity with statistically significant trends at all four time stages except the third trimester. This tendency was confirmed in the proportional odds model showing 28% higher odds of a more complicated mode of delivery among women with a low activity level compared to moderately active women. . We found increasing leisure time physical activity before and during pregnancy associated with a less complicated delivery among low-risk, nulliparous women.
研究母亲休闲时间身体活动与分娩方式之间的关联。基于人群的多中心队列研究。从丹麦难产研究中，我们纳入了2435名未生育过的妇女，她们于2004 - 2005年自然发动分娩后足月分娩了单胎头位婴儿。我们在逻辑回归模型中根据自我报告的四个阶段的身体活动情况分析分娩方式，这四个阶段即怀孕前一年以及孕早期、孕中期和孕晚期。此外，我们将所有四个阶段的身体活动测量值合并为一个变量，用于累积对数的比例优势模型。分娩方式（急诊剖宫产；真空吸引器助产；自然阴道分娩）。急诊剖宫产的几率随着身体活动水平的提高而降低，除孕晚期外，在所有四个时间阶段均有统计学意义的显著趋势。在比例优势模型中证实了这种趋势，该模型显示与中度活动的妇女相比，活动水平低的妇女分娩方式更复杂的几率高28%。我们发现怀孕前及孕期休闲时间身体活动增加与低风险未生育妇女更简单的分娩方式相关。
