Abstract
Abstract
Objective:
To compare the effect of early versus traditional postpartum follow-up intervals on breastfeeding continuation rates 6 months postpartum.
Methods:
This randomized controlled trial enrolled primiparous women planning to breastfeed to a postpartum appointment either 2–3 weeks or 6–8 weeks after delivery. The primary outcome was the breastfeeding rate in each group 5–6 months after delivery. The study was powered to detect a 50% difference between groups assuming a 34% rate of breastfeeding at 6 months. Participants were contacted by phone 5–6 months after delivery to assess outcomes.
Results:
From March 2014 to July 2016, 649 women were screened and 344 enrolled as follows: 172 to 2–3 week and 172 to 6–8 week follow-up. Demographic, delivery, and support characteristics were similar between groups; however, average infant birth weight and the distribution of gestational ages at the time of delivery were different between groups (p < 0.05). Participants in the 2–3 week group had a breastfeeding rate of 57.7% 6 months following delivery and participants in the 6–8 week group had a rate of 59.3%. Early follow-up was associated with a relative risk of 0.97 (95% CI 0.79–1.19, p = 0.80) and an adjusted relative risk of 1.45 (95% CI 0.71–2.95, p = 0.31), when adjusted for confounding variables, for breastfeeding continuation at 5–6 months.
Conclusions:
Breastfeeding rates at 5–6 months postpartum were comparable between both groups; early follow-up was not associated with an increased rate of breastfeeding. At 6 months postpartum, the breastfeeding rate in both groups approximated the Surgeon General's Healthy People 2020 goal of 60.6%.
