University students are at high risk of sexually transmitted infections due to the lack of adequate sexual education, as well as multiple associated factors, which lead to risky sexual practices. It is important to update data about sexual behaviors to identify the main factors associated with sexually risky behaviors. The present study aimed to evaluate the current prevalence of sexually risky practices in medical students. A cross-sectional study was conducted among medical students through an anonymous self-administered online questionnaire including demographic characteristics and sexual behaviors. We used descriptive statistics and multivariable regression to analyze the data collected. A total of 1520 undergraduate medical students aged between 18 and 28 years old were included in the study. Sixty percent of the students were sexually active with a higher proportion in men (70%), likewise, they had an earlier sexual debut (16.5 vs 16.9 years old), and a greater number of lifetime sexual partners than women (3.8 vs 2.2). The main sexual activity in both groups was vaginal sex with high use of condoms (75%), however, most of them (67%) reported having unprotected oral sex. Logistic regression analysis showed that condomless sex was associated with having oral sex, anal sex, and being female. The findings of this study showed that medical university students are involved in risky sexual behaviors, the major risk factor was unprotected oral sex. Based on these results, we recommended designing interventions to improve sexual education and preventive approaches from early stages such as in middle school students to mitigate sexually transmitted infections among medical university students.
大学生由于缺乏足够的性教育以及多种相关因素，面临着性传播感染的高风险，这些因素导致了他们采取危险的性行为。更新关于性行为的数据以确定与性行为风险相关的主要因素非常重要。本研究旨在评估医学生目前性行为风险的流行情况。通过匿名在线问卷调查对医学生进行了横断面研究，包括人口统计学特征和性行为。我们使用描述性统计和多变量回归来分析收集的数据。共有 1520 名年龄在 18 至 28 岁之间的本科医学生参与了这项研究。60%的学生有过性行为，其中男性比例更高（70%），同样，他们的性初潮更早（16.5 岁对 16.9 岁），性伴侣数量也多于女性（3.8 对 2.2）。两组学生的主要性行为都是阴道性交，且避孕套使用率较高（75%），但大多数人（67%）报告有过无保护的口交。逻辑回归分析表明，无保护的性行为与口交、肛交和女性有关。这项研究的结果表明，医科大学生存在性行为风险，主要的风险因素是无保护的口交。基于这些结果，我们建议设计干预措施，从中学阶段开始加强性教育和预防措施，以减轻医科大学生中的性传播感染。
