Determinant factors of insufficient and excessive gestational weight gain and maternal–child adverse outcomes

Abstract Objective To estimate the magnitude and determinant factors of insufficient and excessive gestational weight gain (GWG) and its relation with maternal–child adverse outcomes. Methods This was a prospective study with 173 pregnant women and their newborns monitored at a primary health care facility in Rio de Janeiro. Multinomial regression models were employed, having as the outcome the adequacy of GWG (insufficient, adequate, or excessive). Covariables were classified as biological, socioeconomic, reproductive, behavioral, and nutritional. Results Forty-one percent of pregnant women had insufficient GWG and 22.0% had excessive GWG. Pregestational overweight was associated with insufficient GWG (odds ratio [OR] 0.19, 95% confidence interval [CI] 0.05–0.78), and pregestational obesity was associated with excessive GWG (OR 4.66, 95% CI 1.34–19.08). Also associated with insufficient GWG were a stature
