A cross-sectional study was conducted to measure the prevalence of condom use in the last sexual intercourse and associated factors among university students. Undergraduate students from a public university aged 18 and over of the Rio Grande (RS) campuses were eligible. A systematic single-stage sampling was used, based on class lists and self-administered questionnaire. Descriptive, bivariate and multivariable analyses were employed, with Poisson regression for the latter two. Most of the 1,215 university students included in the analysis were aged 20 to 29 (65.6%) and 69.3% began their sexual life before the age of 18. The prevalence of condom use in the last intercourse was 41.5% (95%CI: 38.7-44.3). Male gender, lower age group, condom use at first sexual intercourse, older age of onset of sexual activity, not having a partner and casual partner in the last sexual intercourse increased the likelihood of condom use.
开展了一项横断面研究，以测量大学生上次性行为中使用避孕套的 prevalence 及相关因素。来自南里奥格兰德州（RS）公立大学 18 岁及以上的本科生符合条件。基于班级名单和自填问卷采用了系统单阶段抽样。采用了描述性、双变量和多变量分析，后两者采用泊松回归。纳入分析的 1215 名大学生中，大多数年龄在 20 至 29 岁之间（65.6%），69.3%在 18 岁之前开始性生活。上次性交时使用避孕套的 prevalence 为 41.5%（95%CI：38.7 - 44.3）。男性、年龄较小的年龄组、首次性行为时使用避孕套、性活动开始年龄较大、上次性行为中没有固定伴侣和临时伴侣会增加使用避孕套的可能性。
