Continuation Rates of Hormonal Intrauterine Devices in Adolescents and Young Adults when Placed for Contraceptive and Non-Contraceptive Indications

Objective: This study aimed to estimate and compare continuation rates of hormonal intrauterine devices (IUDs) when placed for contraceptive or menstrual management indications in adolescents and young adults.Study Design: We conducted a secondary analysis of a prospectively collected database of all hormonal IUD insertions from January 1, 2017 through December 31, 2020, with at least 1-year follow-up, across four Adolescent Medicine practices. IUD insertions without known indication were excluded.Results: A total of 936 IUD insertions were attempted, 45% for contraception only, 18% for menstrual management only, and 37% for both indications. Insertion was successful in 868 (93%) attempts, and success did not differ by indication (p = 0.74). The mean age at insertion was 18.9 years (SD = 2.4 years), with no difference by indication. Of the completed insertions, 650 (75%) had at least one follow-up during the data analysis period. Excluding those without follow-up, the overall continuation rates were 77% at 1 year, 66% at 2 years, and 54% at 3 years. While continuation rates did not differ by indication at 1 year, at 3 years, continuation was highest among those who sought the device for menstrual management only (contra-ception = 53%, menstrual = 57%, both = 53%, p < 0.01) Malposition was rare (4.0%), as was device expulsion (2.5%), and these did not differ by indication.Conclusion: IUD continuation rates were high among adolescents and young adults and did not significantly differ when placed for contraceptive or non-contraceptive indication in the first year of use. Implications: Adolescents and young adults may seek the hormonal IUD for contraception and/or menstrual management. Our study found that IUD continuation rates were high at 1 year regardless of the indication for utilization. (c) 2023 Elsevier Inc. All rights reserved.
