To understand the associations between awareness, attitudes, and intentions to use long-acting reversible contraceptives (LARCs) among youth seeking induced abortion services in Shanghai, China.
A cross-sectional survey was carried out among 1,215 nulliparous youth with unintented pregnancies in 41 hospitals of Shanghai, China, through a stratified sampling process between January and May 2019. Multivariable logistic regression was used to test the associations between awareness, attitudes and intentions to use LARCs.
Around 70% of youth had heard of at least one method of LARCs. About 38% of youth perceived that the copper-bearing intrauterine contraceptive device (Cu-IUD) was safe; the rate was 8% and 7%, respectively, for levonorgestrel-releasing intrauterine system (LNG-IUS) and subdermal implants. Less than 40% of youth thought Cu-IUD was effective in contraception, and it was around 6% for LNG-IUS and subdermal implants. Overall, less than 8% of youth expressed intentions to use LARCs. Positive attitudes towards LARCs were highly associated with the intentions to use LARCs [adjusted Odds Ratio (OR) 3.22, 95% confidence interval (CI) 1.96-5.42, < 0.001].
Low awareness and negative attitudes towards LARCs were found in this study, and the negative attitudes towards LARCs could contribute to low intentions to use LARCs among youth who had already experienced unintended pregnancies.
了解在中国上海寻求人工流产服务的青年对长效可逆避孕措施（LARC）的认知、态度和使用意愿之间的关联。
本研究于 2019 年 1 月至 5 月期间，通过分层抽样，在中国上海的 41 家医院对 1215 名意外怀孕的未婚青年进行了一项横断面调查。采用多变量逻辑回归检验认知、态度与使用 LARC 意愿之间的关联。
约 70%的青年听说过至少一种 LARC 方法。约 38%的青年认为含铜宫内节育器（Cu-IUD）安全；左炔诺孕酮宫内节育系统（LNG-IUS）和皮下埋植剂的比例分别为 8%和 7%。不到 40%的青年认为 Cu-IUD 避孕有效，LNG-IUS 和皮下埋植剂的比例约为 6%。总体而言，不到 8%的青年表示有使用 LARC 的意愿。对 LARC 的积极态度与使用 LARC 的意愿高度相关（调整后的优势比 [OR] 3.22，95%置信区间 [CI] 1.96-5.42， < 0.001）。
本研究发现，青年对 LARC 的认知度较低，对 LARC 的态度消极，而对 LARC 的消极态度可能导致已经经历意外怀孕的青年使用 LARC 的意愿较低。
