*Adjusted for maternal age (years), occupation (currently not working; currently working), education level (secondary school or lower; high school graduate; college/university or above), parity (0; 1; ≥2), prepregnancy body mass index (kg/m2), gestational diabetes (yes; no), gestational age (preterm; not preterm), gestational weight gain (kg), caesarean section (yes; no), infant gender (boy; girl), birth weight (g), admission to neonatal intensive care unit (yes; no) and any breast feeding at 6 months (yes; no). The models only included those with complete follow-up data for 12 months (n=1709).
