Gestational Weight Gain and Postpartum Depression in Women with Class III Obesity.

OBJECTIVE: We investigated the association between gestational weight gain (GWG) and postpartum depression (PPD) in women with class III obesity. STUDY DESIGN: This is a retrospective cohort of women with body mass index (BMI) ≥ 40 kg/m2 at entry to care, first prenatal visit ≤14 weeks gestation, with singleton, nonanomalous pregnancies who delivered at term from July 2013 to December 2017. Women missing data regarding PPD were excluded. Primary outcome was PPD; classified as Edinburgh Postnatal Depression Scale (EPDS) score >13/30 or provider's report of depression. Participants were classified, according to Institute of Medicine GWG guidelines (11-20 pounds), as either less than 11 pounds (LT11) or at/more than 11 pounds (GT11). Bivariate statistics compared demographics and pregnancy characteristics. Logistic regression used to estimate odds of primary outcome. RESULTS: Of 275 women, 96 (34.9%) gained LT11 and 179 (65.1%) gained GT11 during pregnancy. The rate of PPD was 8.7% (n = 24), 9 (9.4%) in the LT11 group and 15 (8.4%) in the GT11 group (p = 0.82, odds ratio: 1.13, 95% confidence interval [CI]: 0.48, 2.69). When controlling for entry BMI and multiparity, adjusted odds of PPD was 1.07 (95% CI: 0.44, 2.63). No correlation was found between GWG and EPDS. CONCLUSION: A relationship between GWG and PPD in class III obese women was not found in this cohort.
