Abstract

Objective: We aimed to evaluate the rates of short interpregnancy interval pregnancies and deliveries among women who receive immediate postpartum LARC. Study Design: We conducted a retrospective cohort study of all women who delivered at Montefiore Medical Center between January 2015 and June 2016 (N = 9561). In this cohort, we identified all repeat deliveries and pregnancies within 18 months of the initial delivery. Using logistic regression models, we compared rates of short interpregnancy interval delivery and pregnancy among recipients of an immediate postpartum IUD, immediate postpartum implant, and no immediate postpartum LARC, adjusting for covariates including patient age, mode of delivery, socioeconomic status, and race. Results: In our cohort, 12.9% of patients received immediate postpartum LARC. The rates of short interpregnancy interval delivery were 3.3% (N = 259/7833) among patients who did not receive immediate postpartum LARC, 1% (N = 6/595) among immediate postpartum IUD recipients, and 0.4% (N = 2/562) among immediate postpartum implant recipients. The rates of short interpregnancy interval pregnancy were 13.8% (N = 1082/7833) among patients who did not receive immediate postpartum LARC, 7.4% (N = 44/595) among immediate postpartum IUD recipients, and 5.2% (N = 29/562) among immediate postpartum implant recipients. Both recipients of immediate postpartum IUDs and immediate postpartum implants had lower rates of short interpregnancy interval delivery and pregnancy compared to patients who did not receive immediate postpartum LARC. Conclusions: This study confirms that women who received immediate postpartum IUDs and implants have lower rates of short interpregnancy interval pregnancies. Implications: Making immediate postpartum LARC widely available is a promising public health approach to help women achieve a longer interpregnancy interval.
