PR_adj = prevalence ratio adjusted by cluster effect and all other predictors entering the model of Poisson multivariate regression analysis (maternal age, skin color, education, marital status, number of pregnancies, number of childbirths, previous C-sections, history of medical conditions, smoking, prenatal coverage, prenatal adequacy, hospitalization coverage, gestational age at hospital admission, gestational age at delivery, mode of delivery, onset of labor, access to referral center, and delays).
*There were 1218 cases excluded due to at least one missing value for variables entering the model
