Prepregnancy Body Mass Index, Vaginal Inflammation, and the Racial Disparity in Preterm Birth

Prepregnancy body mass index, vaginal inflammation, and the racial disparity in preterm birth.

The authors sought to quantify the overall and race/ethnic-specific relations between prepregnancy body mass index and both preterm birth and vaginal inflammation. Data from a cohort of 11,392 women who enrolled in the multicenter Vaginal Infections and Prematurity Study (1984-1989) at 23-26 weeks' gestation were used.

METHODS Using data from the Boston Birth Cohort, we examined associations of prepregnancy BMI with 189 early (<34 completed weeks) and 277 late (34-36 completed weeks) medically-induced PTBs and 320 early and 61...
