Abstract:
The prevalence of obesity in the US has increased markedly in women in their reproductive years over the past 3 decades, partially due to higher rates of excessive gestational weight gain (GWG) and postpartum weight retention. Few studies have considered mode of delivery as an independent risk factor for postpartum weight retention and long-term obesity. METHODS: This was an IRB-approved prospective cohort study of 2,747 first-time mothers, aged 18 to 35 with singleton pregnancies. Postpartum weight retention was measured at 1 year after delivery and was defined as weight at 1 year compared to weight just before becoming pregnant. Logistic regression models assessed the association between mode of first delivery and subsequent weight retention of 10 pounds or more, adjusting for key confounders including pre-pregnancy body mass index, GWG, age, education, poverty status, smoking, race/ethnicity, pregnancy complications, gestational age, breastfeeding, and exercise habits during pregnancy and the first year after delivery. RESULTS: At 12 months after delivery the women who had delivered by cesarean were more likely to have a postpartum weight retention of 10 pounds or more (28.3%), than those who had delivered vaginally (22.8%), unadjusted OR 1.34 (95% CI 1.11–1.61 P =.003). Even after controlling for confounding variables, mode of delivery remained significantly associated with postpartum weight retention of 10 pounds or more, adjusted OR 1.30 (95% CI 1.05–1.60 P =.015). CONCLUSION: Cesarean delivery at first childbirth is associated with increased risk of weight retention of 10 pounds or more at 1 year postpartum.
