探讨主要是低收入妇女产后一年体重保持的危险因素。数据收集自NICHD社区儿童健康网络参与者的774名妇女，这些妇女具有完整的身高和体重信息，这是一项全国性的五个地点的前瞻性队列研究。参与者主要在分娩后立即在医院登记。在产后1个月、6个月和12个月进行的母亲访谈确定了体重保持的风险因素，并包括在6个月和12个月时直接测量身高和体重。逻辑回归评估了产后体重保留对肥胖的独立贡献。女性的平均孕前体重为161.5磅（BMI 27.7 kg/m2）。女性在怀孕期间平均增加32磅，产后1年平均体重为172.6磅（BMI 29.4kg/m2）。大约75%的妇女产后1年比孕前重，其中47.4%保留超过10磅，24.2%超过20磅。保持至少20磅的女性通常是非裔美国人，年轻，贫穷，受教育程度较低，或公共保险。种族和社会经济差异与孕前高BMI和怀孕期间体重过度增加有关，6个月时母乳喂养和适度运动会减弱这种关联。在孕前BMI正常的39.8人中，三分之一在产后1年变得超重或肥胖。产后体重保持是产后1年肥胖风险的重要因素，包括孕前体重正常的妇女。产后，潜在的可改变的行为可能会降低风险。
To explore risk factors for postpartum weight retention at one year after delivery in predominantly low income women. Data were collected from 774 women with complete height and weight information from participants in the NICHD Community Child Health Network, a national five-site, prospective cohort study. Participants were enrolled primarily in the hospitals immediately after delivery. Maternal interviews conducted at 1, 6, and 12 months postpartum identified risk factors for weight retention and included direct measurement of height and weight at 6 and 12 months. Logistic regression assessed the independent contribution of postpartum weight retention on obesity. Women had a mean prepregnancy weight of 161.5 lbs (BMI 27.7kg/m2). Women gained a mean of 32 lbs while pregnant and had a 1 year mean postpartum weight of 172.6 lbs (BMI 29.4kg/m2). Approximately 75% of women were heavier 1 year postpartum than they were prepregnancy, including 47.4% retaining over 10 lbs and 24.2% over 20 lbs. Women retaining at least 20 lbs were more often African American, younger, poor, less educated, or on pubic insurance. Race and socioeconomic disparities were associated with high pre-pregnancy BMI and excessive weight gain during pregnancy, associations which were attenuated by breastfeeding at 6 months and moderate exercise. Of the 39.8 with normal prepregnancy BMI, one third became overweight or obese 1 year postpartum. Postpartum weight retention is a significant contributor to the risk for obesity 1 year postpartum, including for women of normal weight prepregnancy. Postpartum, potentially modifiable behaviors may lower the risk.
