Abstract

OBJECTIVE:

The purpose of this study was to determine contraceptive continuation and repeat pregnancy rates in adolescents who are offered immediate postpartum etonogestrel implant (IPI) insertion.

STUDY DESIGN:

Participants in an adolescent prenatal-postnatal program were enrolled in a prospective observational study of IPI insertion (IPI group, 171) vs other methods (control group, 225). Contraceptive continuation and repeat pregnancies were determined.

RESULTS:

Implant continuation at 6 months was 96.9% (156/161 participants); at 12 months, the continuation rate was 86.3% (132/153 participants). At 6 months, 9.9% of the control participants were pregnant (21/213); there were no IPI pregnancies. By 12 months, 18.6% of control participants (38/204) experienced pregnancy vs 2.6% of IPI recipients (4/153; relative risk, 5.0; 95% confidence interval [CI], 1.9-12.7). Repeat pregnancy at 12 months was predicted by not receiving IPI insertion (odds ratio, 8.0; 95% CI, 2.8-23.0) and having >1 child (odds ratio, 2.1; 95% CI, 1.1-4.3; P = .03).

CONCLUSION:

IPI placement in adolescents has excellent continuation 1 year after delivery; rapid repeat pregnancy is significantly decreased compared with control participants.
