摘要

摘要: 目的探究医学生性取向、性行为及艾滋病（acquired immunodeficiency syndrome，AIDS）相关知识随年级变化的特点。方法整群抽取某医科大学2015级本科新生876人，采用自编大学生艾滋病相关知识、性取向和行为问卷进行每年一次、共四次的匿名调查，采用描述性流行病学方法进行统计描述。结果不同调查批次的医学生的性取向分布的差异有统计学意义（χ²=26.223，P=0.036）。公开的同性恋占同性恋总人数的比例有上升的趋势（χ_趋势²=4.150，P=0.042）。随访研究中医学生对艾滋病相关知识的总知晓率呈上升的趋势（χ_趋势²=23.462，P < 0.001）。医学生在过去半年中总体性行为和男男同性性行为的发生率随年级增长呈上升趋势（χ_趋势²=4.450，P=0.035；χ_趋势²=6.738，P=0.009），第二和第三次随访时，男男同性性行为中偶尔使用和从来不用安全套的比例有所增加，差异有统计学意义（χ²=7.935，P=0.047）。结论医学生性安全防护意识薄弱，学校应持续加强各个年级的医学生艾滋病宣传防治教育，完善学校性健康教育机制。

Abstract: Objective To explore the characteristics of medical sexual orientation, sexual behavior and acquired immunodeficiency syndrome(AIDS) related knowledge changing with grade. Methods A group of 876 undergraduate students of 2015 in a medical university were selected to conduct an anonymous survey once a year and a total of four times using self-compiled questionnaires on AIDS-related knowledge, sexual orientation and behavior of college students. Descriptive epidemiological methods were adopted for statistical description. Results The distribution of sexual orientation among medical students with different survey batches was statistically significant (χ²=26.223, P=0.036). The proportion of openly gay people in the total number of homosexuals showed an increasing trend (χ_trend²=4.150, P=0.042). Follow-up study of Chinese medicine students on AIDS related knowledge of the overall rate of increased (χ_trend²=23.462, P < 0.001). The incidence of general sexual behavior and male homosexual sex among medical students in the past six months showed an increasing trend with grade growth (χ_trend²=4.450, P=0.035; χ_trend²=6.738, P=0.009). At the second and third follow-ups, the proportion of men who used condoms occasionally and never used condoms increased, and the difference was statistically significant (χ²=7.935, P=0.047). Conclusions Due to the weak awareness of medical sexual safety protection, the school should continue to strengthen the AIDS publicity and prevention education of medical students in all grades, and improve the school sexual health education mechanism.
