This study analyzed the effects of gestational weight gain and breastfeeding on postpartum weight retention. The study followed 2,607 women from the BRISA cohort. The variables were age, socioeconomic status, parity, pre-gestational body mass index, gestational weight gain, duration of maternal breastfeeding, length of postpartum follow-up, and postpartum weight gain. Structural equation modeling was used to evaluate the total, direct, and indirect effects of the explanatory variables on postpartum weight retention. An increase of one standard deviation in gestational weight gain corresponded to a significant increase of 0.49 standard deviations in postpartum weight retention (p < 0.001). An increase of one standard deviation in duration of breastfeeding corresponded to mean decrease of 0.10 standard deviations in postpartum weight retention (p < 0.001). Independently of pre-gestational BMI, gestational weight gain is a risk factor and duration of breastfeeding is a protective factor against postpartum weight retention.
