Study Objective

The Chilean legislation forbids induced abortion, so little is known of the young women who have abortions and what determinants are associated with this practice. In this study we examined the association between adolescents and young women who have had induced abortions and socioeconomic status and compared them with counterparts who reported not having a history of abortion.

Design, Setting, Participants, and Main Outcome Measures

Drawing on the 2015 Chilean National Youth Survey, a population-based sample of general community youth aged 15-29 years, we conducted a study on 2439 sexually active females. Bivariate and multiple logistic regression was used to examine the relationship between participants who had induced abortions and participants that had not according to socioeconomic status (low, middle, high), while controlling for demographic, sexual behavior, and cultural covariates.

Results

5.15% (n = 129) of participants declared having induced an abortion in the past. Participants with high socioeconomic status had 4.89 (95% confidence interval, 1.44-16.51) higher odds of induced abortion compared with participants with low socioeconomic status. Those with middle socioeconomic status had 1.8 (95% confidence interval, 1.02-3.24) higher odds of induced abortion compared with those with low socioeconomic status. Urban or rural residence, indigenous identification, age of sexual debut, contraceptive use at the time of sexual debut, adolescent pregnancy, and religious and political identification did not correlate with induced abortion rates.

Conclusion

In Chile, where induced abortion is legally restricted, a social gradient was found in the chance of having had an induced abortion according to socioeconomic status; adolescent and young women with higher socioeconomic advantage reported more induced abortions compared with those with low socioeconomic status.

根据智利的社会经济状况进行的人工流产。

学习目标

智利立法禁止人工流产，因此对进行人工流产的年轻女性以及与这种做法相关的决定因素知之甚少。在这项研究中，我们检查了进行过人工流产的青少年和年轻女性与社会经济地位之间的关联，并将她们与报告没有流产史的同行进行了比较。

设计、设置、参与者和主要结果测量

我们利用 2015 年智利全国青年调查（基于人口的 15-29 岁普通社区青年样本）对 2439 名性活跃的女性进行了研究。根据社会经济地位（低、中、高），在控制人口、性行为和文化协变量的同时，使用双变量和多元逻辑回归来检查进行人工流产的参与者与未进行人工流产的参与者之间的关系。

结果

5.15% (n = 129) 的参与者声称过去曾进行过人工流产。与社会经济地位低的参与者相比，社会经济地位高的参与者进行人工流产的几率高 4.89（95% 置信区间，1.44-16.51）。与社会经济地位低的人相比，中等社会经济地位的人进行人工流产的几率高 1.8（95% 置信区间，1.02-3.24）。城市或农村居住地、土著身份、首次性行为年龄、首次性行为时使用的避孕药具、青少年怀孕以及宗教和政治认同与人工流产率无关。

结论

在法律限制人工流产的智利，根据社会经济地位，人工流产的几率存在社会梯度；与社会经济地位较低的女性相比，具有较高社会经济优势的青少年和年轻女性报告的人工流产次数更多。
