We sought to examine the relation between recommended levels of physical activity during pregnancy and pregnancy outcomes.
We conducted an observational study with energy expenditure, aerobic fitness, and sleeping heart rate measured in 44 healthy women in late pregnancy. Medical records were examined for pregnancy outcome.
Active women, who engaged in > or = 30 minutes of moderate physical activity per day, had significantly better fitness and lower sleeping heart rate compared to the inactive. Duration of second stage of labor was 88 and 146 minutes in the active vs inactive women, respectively (P = .05). Crude odds ratio of operative delivery in the inactive vs the active was 3.7 (95% confidence interval, 0.87-16.08). Birthweight, maternal weight gain, and parity adjusted odds ratio was 7.6 (95% confidence interval, 1.23-45.8). Neonatal condition and other obstetric outcomes were similar between groups.
Active women have better aerobic fitness as compared to inactive women. The risk for operative delivery is lower in active women compared to inactive, when controlled for birthweight, maternal weight gain, and parity. Further studies with larger sample size are required to confirm the association between physical activity and pregnancy outcomes.
我们旨在探讨孕期推荐体力活动水平与妊娠结局之间的关系。
我们对 44 名健康孕妇进行了一项观察性研究，测量了能量消耗、有氧运动能力和睡眠时心率。查阅了医疗记录以了解妊娠结局。
与不活动的孕妇相比，每天进行>或= 30 分钟适度体力活动的活跃孕妇具有更好的体能和更低的睡眠时心率。活跃组和不活跃组第二产程的持续时间分别为 88 和 146 分钟（P=.05）。不活动组与活跃组相比，剖宫产的粗比值比为 3.7（95%置信区间，0.87-16.08）。经出生体重、产妇体重增加和产次调整后比值比为 7.6（95%置信区间，1.23-45.8）。两组新生儿情况和其他产科结局相似。
与不活动的孕妇相比，活跃的孕妇具有更好的有氧运动能力。在控制了出生体重、产妇体重增加和产次后，活跃孕妇的剖宫产风险低于不活跃孕妇。需要进一步的研究以确认体力活动与妊娠结局之间的关联。
