目的：探讨妊娠体重变化对肥胖妇女妊娠结局的影响。方法：对120,251名分娩足月、活产、独生儿的肥胖孕妇进行了一项基于人群的队列研究，根据肥胖级别和总的妊娠体重增加来评估4种妊娠结局(先兆子痫、剖宫产、小于胎龄儿和大胎龄儿)的风险。结果：超重或肥胖孕妇的妊娠体重增加率低于目前推荐的15磅，与先兆子痫、剖腹产和大胎龄出生的风险显著降低，而小于胎龄出生的风险更高。美国国立卫生研究院每个肥胖级别(30-34.9、3535.9和40.0 kg/m(2))的结果是相似的，但孕期体重增加量不同。结论：肥胖孕妇体重有限或没有体重增加都有良好的妊娠结局。
OBJECTIVE: To examine the effect of gestational weight change on pregnancy outcomes in obese women.METHODS: A population-based cohort study of 120,251 pregnant, obese women delivering full-term, liveborn, singleton infants was examined to assess the risk of four pregnancy outcomes (preeclampsia, cesarean delivery, small for gestational age births, and large for gestational age births) by obesity class and total gestational weight gain.RESULTS: Gestational weight gain incidence for overweight or obese pregnant women, less than the currently recommended 15 lb, was associated with a significantly lower risk of preeclampsia, cesarean delivery, and large for gestational age birth and higher risk of small for gestational age birth. These results were similar for each National Institutes of Health obesity class (30-34.9, 3535.9, and 40.0 kg/m(2)), but at different amounts of gestational weight gain.CONCLUSION: Limited or no weight gain in obese pregnant women has favorable pregnancy outcomes.
