This study aimed to assess the association between perceived social support and induced abortion among young women in Lima, Peru. In addition, prevalence and incidence of induced abortion was estimated.
METHODS/PRINCIPAL FINDINGS: A cross-sectional study enrolling women aged 18-25 years from maternal health centers in Southern Lima, Peru, was conducted. Induced abortion was defined as the difference between the total number of pregnancies ended in abortion and the number of spontaneous abortions; whereas perceived social support was assessed using the DUKE-UNC scale. Prevalence and incidence of induced abortion (per 100 person-years risk) was estimated, and the association of interest was evaluated using Poisson regression models with robust variance. A total of 298 women were enrolled, mean age 21.7 (± 2.2) years. Low levels of social support were found in 43.6% (95%CI 38.0%-49.3%), and 17.4% (95%CI: 13.1%- 21.8%) women reported at least one induced abortion. The incidence of induced abortion was 2.37 (95%CI: 1.81-3.11) per 100 person-years risk. The multivariable model showed evidence of the association between low perceived social support and induced abortion (RR = 1.94; 95%CI: 1.14-3.30) after controlling for confounders.
There was evidence of an association between low perceived social support and induced abortion among women aged 18 to 25 years. Incidence of induced abortion was similar or even greater than rates of countries where abortion is legal. Strategies to increase social support and reduce induced abortion rates are needed.
本研究旨在评估秘鲁利马年轻女性感知到的社会支持与人工流产之间的关系。此外，还估计了人工流产的流行率和发生率。
方法/主要发现：本研究是在秘鲁南部利马的母婴保健中心招募了 18-25 岁的女性进行的一项横断面研究。人工流产定义为人工流产与自然流产总数之差；而感知到的社会支持则使用 DUKE-UNC 量表进行评估。估计了人工流产的流行率和发生率（每 100 人年风险），并使用泊松回归模型评估了感兴趣的关联，该模型采用了稳健方差。共纳入 298 名女性，平均年龄 21.7（±2.2）岁。43.6%（95%CI：38.0%-49.3%）的女性社会支持水平较低，17.4%（95%CI：13.1%-21.8%）的女性至少报告了一次人工流产。人工流产的发生率为每 100 人年风险 2.37（95%CI：1.81-3.11）。多变量模型显示，在控制了混杂因素后，低感知社会支持与人工流产之间存在关联（RR=1.94；95%CI：1.14-3.30）。
在 18 至 25 岁的女性中，低感知社会支持与人工流产之间存在关联。人工流产的发生率与合法堕胎的国家相似，甚至更高。需要采取增加社会支持和降低人工流产率的策略。
