Contraceptive Choice and Sexual Behaviors in Both-Sex Attracted Adolescents: A Retrospective Cohort Study

Study Objective

Bisexual adolescents have higher rates of unintended pregnancy than their heterosexual peers and increased rates of high-risk sexual behaviors. They may be less likely to use effective contraception, though limited data is available. This study sought to compare contraceptive choice and sexual risk behaviors of both-sex attracted and opposite-sex attracted adolescents and young adults (AYA) presenting to a contraception clinic.

Methods

A retrospective chart review of AYA aged 14-24 years who presented for an initial visit to a contraception clinic from 2014 to 2020. The primary outcome was contraceptive choice (long-acting reversible contraception (LARC), non-LARC, or nothing). Secondary outcomes included sexual behaviors. Results were analyzed using Pearson's chi-square and Wilcoxon tests.

Results

A total of 2369 AYA were included in this study. Both-sex attracted and opposite-sex attracted patients were similar in age, race, and ethnicity. There was no difference between groups in percentage selecting LARC (71% vs 66.1%, P = .11). Both-sex attracted patients reported a younger age at first sex (14.6 years vs 15.5 years, P < .001), more lifetime sexual partners (4.1 vs 2.8, P < .001), and a higher prevalence of forced intercourse (21.9% vs 8.8%, P < .001).

Conclusions

Both-sex attracted and opposite-sex attracted AYA patients chose LARCs at similar rates in a setting with standardized contraceptive counseling. Both-sex attracted patients had more sexual risk behaviors. Healthcare providers should be inclusive in their approach to obtaining sexual health histories and providing contraceptive counseling and be cognizant that adolescents with both-sex attraction may be at higher risk of forced intercourse.
