OBJECTIVES
To assess factors associated with post-abortion contraceptive discontinuation.
METHOD
This cross-sectional study addressed 111 women aged 18-49 attending Primary Health Care Facilities in São Paulo/SP, Aracaju/SE, and Cuiabá/MT, Brazil, who reported an abortion five years before the interview held in 2015-2017. Kaplan-Meier estimates and Cox Regression were used for data analysis.
RESULTS
Oral hormonal contraceptives, male condoms, and injectable contraceptives were the methods most frequently used. The contraceptive discontinuation rate was 41.8% in the 12 months after the abortion. The pill was the method most frequently abandoned (58.3%); male condoms were the method that failed the most (72.7%), and injectable contraceptives were the method most frequently switched (50.0%). Being up to 24 years old, having ten or more years of education, having three or more children, and a desire to wait longer before becoming pregnant again were associated with post-abortion contraceptive discontinuation.
CONCLUSION
Short-acting contraceptive methods were predominant among post-abortion women. The type of discontinuation varied according to the type of method used. The factors associated with contraceptive discontinuation were age, education, parity, and reproductive intention.
目的
评估与人工流产后避孕措施停用相关的因素。
方法
这项横断面研究针对的是111名年龄在18 - 49岁之间的女性，她们在巴西圣保罗/圣保罗州、阿拉卡茹/塞尔希培州和库亚巴/马托格罗索州的初级卫生保健机构就诊，这些女性在2015 - 2017年进行的访谈前五年报告有过人工流产。采用Kaplan - Meier估计法和Cox回归进行数据分析。
结果
口服激素避孕药、男用避孕套和注射用避孕药是最常使用的避孕方法。人工流产后12个月内避孕措施停用率为41.8%。避孕药是最常被放弃的方法（58.3%）；男用避孕套是失败率最高的方法（72.7%），注射用避孕药是最常被更换的方法（50.0%）。年龄在24岁及以下、接受过十年或以上教育、育有三个或以上子女以及希望在再次怀孕前等待更长时间与人工流产后避孕措施停用有关。
结论
短效避孕方法在人工流产后女性中占主导地位。停用类型因所使用方法的类型而异。与避孕措施停用相关的因素包括年龄、教育程度、生育状况和生育意愿。
