Abstract: Objective To determine the association of postpartum contraceptive use with repeat deliveries among adolescents and youth. Design Retrospective, observational analysis of electronic health record data. Setting Single, urban facility in Denver, Colorado, USA. Population Women aged 10 – 24 who gave birth between January 1, 2011 and December 31, 2015. Outcome Measures Postpartum contraceptive use and time to subsequent delivery. Results Among 4,068 women, 1,735 (43%) used postpartum contraception. In adjusted analyses, characteristics associated with contraceptive use included Hispanic ethnicity (RR 1.1, p = 0.03), incremental prenatal visits (RR 1.01, p = 0.047), and attendance at postpartum care (RR 1.60, p Conclusion Postpartum LARC use reduced the risk of repeat pregnancy with significant increase in time to the next delivery. Non-LARC use was no different from no contraceptive use in terms of time to repeat delivery.
