BMI – body mass index, OR – odds ratio, aOR – adjusted odds ratio; CI – confidence interval
*Analysis limited to women with vaginal delivery
†BMI category: underweight (<18.5 kg/m2), normal-weight (18.5-24 kg/m2), and overweight (≥25 kg/m2)
‡Adjusted for maternal education
§Adjusted for maternal parity, education and wealth quintile
