Gestational weight gain and patterns of breastfeeding among patients with class III obesity.
Journal Article (Journal Article)
BACKGROUND: Maternal obesity is associated with delayed lactogenesis and shorter duration of breastfeeding compared to patients with a normal BMI. RESEARCH AIM/QUESTION: We investigated the impact of excessive gestational weight gain, defined as greater than the Institute of Medicine guidelines (>9.1 kg), on the initiation and duration of breastfeeding in patients with class III obesity. METHODS: Retrospective cohort of patients with body mass index ≥40 in first trimester, delivering a singleton term infant at a tertiary care center between July 2013 and December 2017. Primary outcome was exclusive breastfeeding at discharge and at postpartum visit. Secondary outcomes included any breastfeeding at discharge and postpartum visit, and cessation of breastfeeding by the postpartum visit. Descriptive statistics were used to compare those whose gestational weight gain exceeded (eIOM) versus met (mIOM) Institute of Medicine guidelines. Regression models were performed to adjust for baseline confounding factors. RESULTS: Of 294 women included, 117(39.8%) were in the eIOM group. These women were more likely to be primigravida, have a higher delivery BMI, greater delivery blood loss, and have a neonate admitted to the intensive care unit. Exclusive breastfeeding at discharge was not different between eIOM and mIOM (66.7% vs 70.9%, p = .44), nor did eIOM impact likelihood of exclusive breastfeeding at postpartum visit (40.1% vs 34.2%, p = .31). When controlling for confounding factors, breastfeeding at discharge (aOR 1.54 95% CI [0.68-3.49]) or postpartum visit (aOR 0.67[0.31-1.47]) did not differ between eIOM compared to mIOM. CONCLUSIONS: Among women with class III obesity, excessive gestational weight gain did not impact the rate of exclusive breastfeeding at discharge or postpartum visit.
