Objectives: To evaluate whether timing of etonogestrel (ENG) implant insertion during the postpartum period affects maternal bleeding patterns, body mass index (BMI) and 12-month satisfaction and continuation rates. Study design: This is a secondary analysis of an open, randomized, controlled trial. Postpartum women were block-randomized to early (up to 48 h postpartum) or delayed (6 weeks postpartum) insertion of an ENG implant. Bleeding patterns and BMI were evaluated every 90 days for 12 months. At 12 months, we measured implant continuation rates and used Likert and face scales to measure users' satisfaction. The level of significance was 0.4% (adjusted by Bonferroni test for multiplicity). Results: We enrolled 100 postpartum women; we randomized 50 to early and 50 to delayed postpartum ENG implant insertion. Bleeding patterns were similar between groups. Amenorrhea rates were high in both groups during the follow-up (52%-56% and 46%-62% in the early and delayed insertion group, respectively). Prolonged bleeding episodes were unusual in both groups during the follow-up (0-2%). Maternal BMI was similar between groups and decreased over time. Twelve-month continuation rates were similar between groups (early insertion: 98% vs. delayed insertion: 100%, p=.99). Most participants were either very satisfied or satisfied with the ENG implant in both groups (p=.9). Conclusion: Women who underwent immediate postpartum insertion of the ENG implant have similar bleeding patterns, BMI changes, and 12-month satisfaction and continuation rates compared to those who underwent delayed insertion.
