Effects of Gestational Weight Gain on Delivery Outcomes in an Obese, Low-Income Population.

Objective: To examine the effects of weight gain/loss on delivery outcomes stratified by class of obesity in an obese, low-income, predominantly minority population.

Methods: A retrospective review of a cohort of 1428 women receiving care at a large Medicaid clinic from 2013 to 2016 with pregravid body mass index ≥30 was conducted. Multinomial logistic regression analysis was used to compare differences in gestational weight change to the primary outcomes of birth-weight percentile and delivery type and secondary outcomes of preterm delivery, preterm labor, gestational diabetes mellitus, and gestational hypertension.

Social Determinants of Gestational Weight Gain in an Obese, Low-Income Population.

Objective: To examine how social support factors affect compliance with gestational weight gain (GWG) recommendations in an obese, low-income, predominantly minority population.

Study Design: A retrospective cohort of 772 pregnant women with body mass index > 30 was reviewed. Univariate and multinomial logistic regression analyses were used to compare GWG with pregnancy planning, relationship status, participation in group prenatal care, nutritional education, and demographic factors.
