RR = relative risk; CI = confidence interval
a Model 1: adjusted for maternal age, ethnicity, education, body mass index, gestational weight gain, parity and family history of diabetes, type of conception
b Model 2: adjusted for same variables as in model 1 + neonatal sex
c Model 3: adjusted for same variables as in model 1 + small-for-gestational-age birth
