Postpartum depression, infant feeding practices, and infant weight gain at six months of age.

INTRODUCTION: This study examined postpartum depression (PPD) as a potential risk factor for non-adherence to infant feeding guidelines and subsequent infant weight gain.

METHODS: Participants were mother-infant dyads from the Infant Feeding Practices Study II (N = 1447). Main study variables were PPD, breastfeeding intensity, addition of cereal to infant formula, and age of introduction to solid foods.

RESULTS: In logistic models adjusted for sociodemographic factors, mothers with PPD were 1.57 times (95% confidence interval [CI]: 1.16, 2.13) more likely to breastfeed at low intensity and 1.77 times (95% CI: 1.16, 2.68) more likely to add cereal to infant formula. Although PPD was associated with the early introduction to solid foods (odds ratio: 1.42; 95% CI: 1.07, 1.89), this relationship was not significant after adjusting for potential confounders. A small but significantly greater average weight gain at 6 months was observed among infants of mothers with PPD (10.15 lb, SD = 2.32 vs. 9.85 lb, SD = 2.32).

DISCUSSION: Screening for PPD at well-child visits may lead to improved maternal health outcomes and the prevention of early life risk factors for childhood obesity.
