GWG, gestational weight gain

^aSeparate multiple linear regression analyses; standardized coefficients adjusted for age, education, income, gestational age at delivery, number of weeks since delivery, breastfeeding status and parity

^bCalculated as weight at 12 months postpartum – early pregnancy weight
