To examine the effect of gestational weight change on pregnancy outcomes in obese women.
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.
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, 35-35.9, and 40.0 kg/m(2)), but at different amounts of gestational weight gain.
Limited or no weight gain in obese pregnant women has favorable pregnancy outcomes.
研究肥胖女性孕期体重变化对妊娠结局的影响。
对120251名足月分娩单活胎的肥胖孕妇进行基于人群的队列研究，以评估不同肥胖等级和孕期总体重增加情况下四种妊娠结局（子痫前期、剖宫产、小于胎龄儿出生和大于胎龄儿出生）的风险。
超重或肥胖孕妇孕期体重增加少于目前推荐的15磅，与子痫前期、剖宫产和大于胎龄儿出生的风险显著降低以及小于胎龄儿出生的风险升高相关。美国国立卫生研究院的每个肥胖等级（30 - 34.9、35 - 35.9和40.0 kg/m²）的结果相似，但孕期体重增加量不同。
肥胖孕妇体重增加有限或未增加具有良好的妊娠结局。
