OBJECTIVE
Investigate prevalence of use and knowledge about emergency contraception (EC) among female university students from two higher education institutions.
METHODS
Cross-sectional study with 1,740 undergraduates in the city of Santa Maria (RS), from May to October 2017. Information was collected in a semi-structured and self-administered 24-question questionnaire. The investigated variables were grouped into sociodemographic characteristics, sexual behavior, and knowledge of EC. Logistic regression was used for univariate and multivariate analysis, considering variables that presented p < 0.05. The model was adjusted using the Hosmer-Lemeshow test.
RESULTS
The prevalence of EC use among undergraduates was 52.9%. However, only 11.9% of respondents received guidance on EC, especially on how to use it. Only 0.2% of the participants marked 120 hours as the maximum time of use, and 25.7% considered the EC to be abortive. EC use was associated with the age of first sexual intercourse.
CONCLUSION
EC use had a high prevalence among female university students, however, several gaps in method knowledge still exists and it demonstrates the importance of discussing this issue earlier and planning actions of an informative nature.
目的
调查两所高等教育机构的女大学生紧急避孕（EC）的使用情况和相关知识。
方法
这是一项 2017 年 5 月至 10 月在圣玛丽亚（RS）市进行的横断面研究，共有 1740 名本科生参与。采用半结构化和自我管理的 24 个问题的问卷收集信息。所调查的变量分为社会人口特征、性行为和 EC 知识。使用单变量和多变量分析进行逻辑回归，考虑到 p<0.05 的变量。使用 Hosmer-Lemeshow 检验对模型进行调整。
结果
本科生中 EC 的使用率为 52.9%。然而，只有 11.9%的受访者接受过 EC 的指导，尤其是关于如何使用它的指导。只有 0.2%的参与者将 120 小时标记为使用的最长时间，而 25.7%的人认为 EC 具有堕胎作用。EC 的使用与首次性行为的年龄有关。
结论
在女大学生中，EC 的使用率较高，但在方法知识方面仍存在一些差距，这表明尽早讨论这个问题并计划开展宣传性质的行动非常重要。
