The Association between Weight-related Variables and Postpartum Depressive Symptoms.

Postpartum depressive symptoms (PPDS) are common, and weight-related variables may be risk factors. In this study, we examined associations between weight-related variables and PPDS in postpartum women. Participants who gave birth within the past 12 months completed an online survey assessing various weight-related variables and PPDS. We examined associations between weight-related variables and PPDS using regression models. Participants (N=315) were 30.1±3.9 years of age and 5.6±3.7 months postpartum. A majority were white (96.2%), married (87.9%), and had a bachelor's degree or higher (70.5%). Having a higher pre-pregnancy body mass index (BMI) and current BMI, lower weight loss at 6 months postpartum, and substantial postpartum weight retention were associated with higher PPDS. There was no relationship between total gestational weight gain, IOM weight gain category, excess weight gain, postpartum weight retention, and pre-pregnancy-to-postpartum change in BMI, and postpartum depressive symptoms. Understanding factors associated with postpartum depressive symptoms can help to develop and implement appropriate screenings/follow-ups and interventions among those at greatest risk. Given the potential connection to PPDS, there is a need for interventions aimed at promoting healthy pre-conception weight and helping women to lose excess pregnancy weight during the postpartum period.
