Adolescent women have a high risk of unintended pregnancy. Currently, there are little data about their choice to initiate long-acting reversible contraception (LARC).
We evaluated the association of age and preference for a LARC vs. a non-LARC method among adolescent participants in the Contraceptive CHOICE Project, comparing those aged 14-17 years to adolescents aged 18-20 years. We then analyzed the association between age and choice of the implant vs. the intrauterine device (IUD) among adolescents.
Of the 5086 women enrolled, 70% (n=3557) of participants chose a LARC method. Among adolescents aged 14-20 years, 69% of 14-17-year-olds chose LARC, while 61% of 18-20-year-olds chose LARC (relative risk 1.16, 95% confidence interval 1.03-1.30). Among adolescents choosing a LARC method, 63% (n=93/148) of the 14-17-year-olds chose the implant, whereas 71% (n=364/510) of the 18-20-year-olds chose the IUD.
Long-acting reversible contraception use is clearly acceptable and common among adolescents enrolled in the Contraceptive CHOICE Project, with the younger group being most interested in the implant.
青春期女性意外怀孕的风险很高。目前，关于她们选择长效可逆避孕措施（LARC）的数据很少。
我们评估了避孕选择项目中青少年参与者的年龄和对 LARC 与非 LARC 方法的偏好之间的关系，将 14-17 岁的青少年与 18-20 岁的青少年进行比较。然后，我们分析了年龄与选择植入物与宫内节育器（IUD）之间的关系。
在纳入的 5086 名女性中，70%（n=3557）的参与者选择了 LARC 方法。在 14-20 岁的青少年中，69%的 14-17 岁青少年选择了 LARC，而 61%的 18-20 岁青少年选择了 LARC（相对风险 1.16，95%置信区间 1.03-1.30）。在选择 LARC 方法的青少年中，63%（n=93/148）的 14-17 岁青少年选择了植入物，而 71%（n=364/510）的 18-20 岁青少年选择了 IUD。
长效可逆避孕措施在避孕选择项目中显然被接受并被青少年广泛使用，年龄较小的群体对植入物最感兴趣。
