烟台市青年学生艾滋病综合干预模式效果评价

  目的  评估烟台市青年学生艾滋病综合干预模式实施效果，为制定艾滋病防治策略提供科学依据。  方法  采用整群抽样对2016级四所高校新生2 000人进行纵向调查，采用广义估计方程分析目标人群艾滋病相关知识、态度、行为等方面的变化趋势，对高校领导等进行个人深入访谈。  结果  三次调查青年学生艾滋病知晓率分别为70.4%、85.9%、95.8%，广义估计方程分析显示目标人群艾滋病知识总知晓率呈逐年上升趋势（Z=-23.42，P < 0.001）。不同类型性行为的发生率维持在较低水平，且未见明显趋势变化，多因素Logistic回归分析模型显示，男性、不知晓艾滋病防治知识、未接受过有关预防艾滋病的宣传服务、未参与过有关预防艾滋病宣传服务的青年学生性行为的发生率更高（均有P < 0.05）。访谈结果显示，与2016年基线调查相比，目前四所高校已有三所学校将艾滋病健康教育纳入教学计划，学校艾滋病疫情通报制度已全面落实。  结论  烟台市高校新生艾滋病知识知晓率相对较低，实施综合干预、建立多部门合作机制是提高在校青年学生艾滋病防治知识、促进安全性行为的最有力措施。

Effect evaluation of compreherive intervention model for HIV/AIDS among college students in Yantai

  Objective  To study the effect of AIDS intervention programs among college students, and to provide fundamental support for the formulating of AIDS prevention strategies.  Methods  A cluster sampling methods was used to conduct a longitudinal follow-up survey among 2 000 freshmen from four colleges in Yantai in 2016, The knowledge, attitudes and behaviors related to AIDS were analyzed by generalized estimating equation analysis method. We also conducted in-depth personal interviews among university leaders.  Results  The awareness rate of AIDS among young students in Yantai was 70.4%, 85.9%, and 95.8%, respectively. The generalized estimating equation showed that the total awareness rate of AIDS knowledge increased year by year (Z=-23.42, P < 0.001). The occurrence of different types of sexual behaviors maintained at a low level, and no obvious trend changes were observed. Multivariate Logistic regression showed that a high occurrence of sexual behaviors among young college students was found related to male, poor knowledge of AIDS prevention, having not received public services related to AIDS prevention, and having not participated in public services related to AIDS prevention (all P < 0.05). Interview results showed that, three of the four colleges have included AIDS health education into their teaching plans, and the AIDS epidemic notification system has been fully implemented.  Conclusions  The awareness rate of AIDS knowledge among college freshmen in Yantai is relatively low. Implementing comprehensive intervention measures and establishing a multi-sectoral cooperation mechanism are the most effective measures to improve the knowledge of AIDS prevention, and promote safe sexual behaviors among young college students.
