Contraceptive implant discontinuation at one year in adults and adolescents: Implications for adolescent reproductive health services
A retrospective cohort of 2,014 etonogestrel or levonorgestrel implant initiators in 2016-2021 found one-year discontinuation at 3.83 per 100 person-years overall, 2.84 in adolescents and 4.16 in adults, with no significant difference. Sequential users had lower hazard (aHR 0.29), and abnormal bleeding was the leading reason. Single-centre findings should not diminish adolescent-specific services.
