Abstract
This systematic review and meta-analysis provide an update of an earlier meta-analysis examining the impact of gestational weight gain (GWG) on postpartum weight retention (PPWR). Thirty-four observational studies were included, and results from 18 studies were combined in meta-analyses. We found that women with excessive GWG retained an additional 2.98 kg (95% CI: 0.59, 5.37 kg, I2 = 91%) at 0.5 years, 1.89 kg (95% CI: 0.90, 2.88 kg, I2 = 61%) at > 0.5-1 year and 2.89 kg (95% CI: 1.74, 4.04 kg, I 2 = 0%) at 2-4 years, compared to women who met the National Academy of Medicine GWG recommendations. Moreover, synthesis of confounder-adjusted regression coefficients showed that each 1 kg increase of GWG corresponded to 0.62 kg (95% CI: 0.22, 1.02 kg, I2 = 96%) additional PPWR at 6-9 months, 0.48 kg (95% CI: 0.14, 0.81 kg, I2 = 93%) at 1-3 years, and 0.31 kg (95% CI: -0.24, 0.86 kg, I2 = 89%) at 5-7 years postpartum. Findings suggest that higher GWG contributes to increased maternal body weight in the short- and long-term after childbirth, independent of prepregnancy body mass index. The heterogeneity of reported data and methodological differences across studies complicate the ability to synthesize data and interpret findings.
