合肥市15~24岁青年学生对艾滋病病毒暴露前后预防的认知与服务使用现况

Awareness and service utilization of HIV preand postexposure prophylaxis among the young students aged 15-24 years in Hefei

目的了解合肥市15~24岁在校青年学生对艾滋病病毒暴露前预防(PrEP)、暴露后阻断(PEP)的认知与服务使用现况,为今后青年学生艾滋病的防治工作提供参考依据。方法2022年5—6月采用分层随机整群抽样方法,抽取合肥市2所不同类型的高校(本科/专科),对抽中学校916名青年学生进行横断面调查。采用χ~2检验进行统计学分析。结果调查的青年学生中,性取向为异性恋占88.4%;12.4%发生过性行为,其中8.8%发生过同性性行为,91.2%发生过异性性行为。最近一次同性性行为中安全套使用率为70.0%,最近一次异性性行为中安全套使用率为83.7%。41.9%听说过PrEP,其PrEP知识知晓率为43.0%,咨询过PrEP和使用过PrEP的比例分别为15.9%和9.4%;38.3%听说过PEP,其PEP知识知晓率为18.2%,咨询过PEP和使用过PEP的比例分别为15.4%和6.0%。结论合肥市青年学生PrEP和PEP的知晓率和使用率均较低。应将PrEP和PEP宣传与校内健康教育宣传相结合,提高青年学生群体认知水平,减少有高危行为的青年学生艾滋病感染风险。
