Abstract：
UNASSIGNED: Induced abortion can seriously harm the physical and mental health of adolescent women. Long-acting reversible contraception (LARC) can effectively reduce unplanned pregnancies and prevent repeated abortions among adolescents. This study aimed to analyse the factors affecting the choice of LARC among adolescents in Chongqing of China.
UNASSIGNED: A total of 555 adolescents who underwent induced abortions for unplanned pregnancies between January 2019 and October 2021 were selected as study subjects. Logistic regression analysis was used to determine the factors affecting adolescent LARC choices following induced abortions.
UNASSIGNED: The factors that affected adolescent LARC choices included an average monthly income ≥ ¥3000 (OR = 3.432, 95% CI: 1.429∼8.244), history of previous abortions (OR = 3.141, 95% CI: 1.632∼6.045), worrying about unplanned pregnancy (OR = 0.365, 95% CI: 0.180∼0.740), parental support for using LARC (OR = 3.549, 95% CI: 1.607∼7.839), sexual partners\' support for using LARC (OR = 2.349, 95% CI: 1.068∼5.167), concerns about using LARC (OR = 0.362, 95% CI: 0.176∼0.745), and willingness to use free IUDs (OR = 13.582, 95% CI: 7.173∼25.717).
UNASSIGNED: Cost is one of the factors affecting LARC choices. Parents and sexual partners may play important role in the choice of LARC.
The study analysed the choice of contraceptive methods and the factors affecting the choice of long-acting reversible contraception methods after induced abortion among adolescents in Chongqing, China. The results showed that the income level, history of previous abortions, extent of worrying about unplanned pregnancy, parents’ and sexual partners’ attitude towards to use long-acting reversible contraception methods, concerns about using long-acting reversible contraception methods, and willingness to use free intrauterine devices were the factors affecting the choice of long-acting reversible contraception methods after induced abortion among adolescents.

摘要：
■人工流产会严重危害青春期女性的身心健康。长效可逆避孕（LARC）可有效减少非计划妊娠，防止青少年反复流产。本研究旨在分析影响重庆市青少年选择LARC的因素。
共有555名在2019年1月至2021年10月期间因计划外怀孕而进行人工流产的青少年被选为研究对象。Logistic回归分析用于确定人工流产后影响青少年LARC选择的因素。
■影响青少年LARC选择的因素包括平均月收入≥3000日元（OR=3.432，95%CI：1.429~8.244），既往流产史(OR=3.141，95%可信区间：1.632~6.045)，担心计划外怀孕(OR=0.365，95%CI：0.180~0.740)，父母对使用LARC的支持(OR=3.549，95%CI：1.607~7.839)，性伴侣对使用LARC的支持(OR=2.349，95%CI：1.068~5.167)，对使用LARC的担忧(OR=0.362，95%CI：0.176~0.745)，和使用免费宫内节育器的意愿（OR=13.582，95%CI：7.173~25.717）。
■成本是影响LARC选择的因素之一。父母和性伴侣可能在LARC的选择中发挥重要作用。
研究分析了重庆市青少年人工流产后避孕方法的选择及影响长效可逆避孕方法选择的因素,中国。结果表明,收入水平,以前堕胎的历史，担心意外怀孕的程度，父母和性伴侣对使用长效可逆避孕方法的态度，对使用长效可逆避孕方法的担忧，和使用免费宫内节育器的意愿是影响青少年人工流产后选择长效可逆避孕方法的因素。
