Abstract OBJECTIVE: To provide a current estimate of the prevalence of prepregnancy obesity in the United States. METHODS: We analyzed 2004-2005 data from 26 states and New York City (n = 75,403 women) participating in the Pregnancy Risk Assessment Monitoring System, an ongoing, population-based surveillance system that collects information on maternal behaviors associated with pregnancy. Information was obtained from questionnaires self-administered after delivery or from linked birth certificates; prepregnancy body mass index was based on self-reported weight and height. Data were weighted to provide representative estimates of all women delivering a live birth in each particular state. RESULTS: In this study, about one in five women who delivered were obese; in some state, race/ethnicity, and Medicaid status subgroups, the prevalence was as high as one-third. State-specific prevalence varied widely and ranged from 13.9 to 25.1\%. Black women had an obesity prevalence about 70\% higher than white and Hispanic women (black: 29.1\%; white: 17.4\%; Hispanic: 17.4\%); however, these race-specific rates varied notably by location. Obesity prevalence was 50\% higher among women whose delivery was paid for by Medicaid than by other means (e.g., private insurance, cash, HMO). CONCLUSION: This prevalence makes maternal obesity and its resulting maternal morbidities (e.g., gestational diabetes mellitus) a common risk factor for a complicated pregnancy.
