目的：孕前肥胖对孕妇及其婴儿构成风险。从1993年到2003年，这项研究使用了大量的基于人群的数据源来检查趋势，以期孕妇的肥胖症患病率在送达活生生的妇女中。研究方法和程序：九个州怀孕风险评估监测系统的数据分析了孕前肥胖症（BMI> 29.0 kg/m（2））的趋势，并按照母亲的人口统计和行为特征分析。预先怀孕的BMI是根据分娩后给管理问卷的自我报告的体重和高度计算的，并从链接的出生证书中获取人口统计学特征。对66,221个出生的样本进行了加权，以调整调查设计，非覆盖和无响应，并代表所有在每个特定状态下实时出生的妇女。抽样的出生占美国所有出生的18.5％。在研究期间，孕前肥胖症增加了69.3％，从1993年的13.0％到1994年至2002年的22.0％。单个州为105％。 2002年至2003年肥胖症患病率最高的女性亚组是那些20至29岁的女性，黑色，有三个或更多的孩子，接受了高中教育，招募了妇女，婴儿和儿童，或 - 杂物。但是，所有检查的妇女亚组在这段时间内至少有43％的孕前肥胖症增加了43％。讨论：这些九个州的妇女中孕前肥胖的流行率正在增加，并且这一趋势对所有人都具有重要意义。生殖医疗保健阶段。
Objective: Pre-pregnancy obesity poses risks to both pregnant women and their infants. This study used a large population-based data source to examine trends, from 1993 through 2003, in the prevalence of pre-pregnancy obesity among women who delivered live infants.Research Methods and Procedures: Data from the Pregnancy Risk Assessment Monitoring System in nine states were analyzed for trends in pre-pregnancy obesity (BMI > 29.0 kg/m(2)) overall and by maternal demographic and behavioral characteristics. Pre-pregnancy BMI was calculated from self-reported weight and height on questionnaires administered after delivery, and demographic characteristics were taken from linked birth certificates. The sample of 66,221 births was weighted to adjust for survey design, non-coverage, and non-response, and it is representative of all women delivering a live birth in each particular state. The sampled births represented 18.5% of all births in the United States.Results: Pre-pregnancy obesity increased 69.3% during the study period, from 13.0% in 1993 to 1994 to 22.0% in 2002 to 2003. The percentage increase ranged from 45% to 105% for individual states. Subgroups of women with the highest prevalence of obesity in 2002 to 2003 were those who were 20 to 29 years of age, black, had three or more children, had a high school education, enrolled in Women, Infants, and Children, or were non-smokers. However, all subgroups of women examined experienced at least a 43% increase in pre-pregnancy obesity over this time period.Discussion: The prevalence of pre-pregnancy obesity is increasing among women in these nine states, and this trend has important implications for all stages of reproductive health care.
