To assess population-level trends in the prevalence of pre-pregnancy obesity among women delivering live infants between 1993 and 2003.
Analyzed survey data from the Pregnancy Risk Assessment Monitoring System (PRAMS) linked to birth certificates across nine US states.
Sampled N=66,221 live births (weighted to represent 18.5% of all US births), defining pre-pregnancy obesity as a maternal body mass index greater than 29.0 kg/m² derived from self-reported height and weight.
Pre-pregnancy obesity prevalence increased by 69.3% overall, rising from 13.0% in 1993–1994 to 22.0% in 2002–2003, with individual state increases ranging between 45% and 105%.
All examined maternal demographic subgroups experienced at least a 43% increase, with the highest 2002–2003 prevalence observed among Black women, mothers aged 20–29, multiparous women with three or more children, high school graduates, and WIC enrollees.
