目的 了解黟县中学生艾滋病防治知识知晓水平和行为干预效果。方法 采用整群抽样的方法,2015年11~12月抽取黟县7所初高中的初三、高一及高二共697名学生为调查对象,首先开展艾滋病防治知识基线调查,之后在该人群中开展艾滋病防治知识健康教育和发放艾滋病防治知识宣传材料等干预活动,分别在干预活动结束时和干预2 W后对该人群再次进行艾滋病防治知识调查,分析干预前后调查对象艾滋病防治知识知晓率的差异,评估干预效果。结果 697名学生干预前的艾滋病防治知识知晓率为73.31%,干预活动结束时提高到96.42%,干预2 W后为 95.18%,干预前后知晓率差异有统计学意义(χ²=1780,P＜0.01)。干预前高中学生的艾滋病防治知识知晓率与初中学生比较,差异有统计学意义(χ²=20.47,P＜0.01);城区初中生的艾滋病防治知识知晓76.88%,乡镇初中生为65.79%,差异有统计学意义(χ²=44.67,P＜0.01);普通高中学生的艾滋病防治知识知晓80.36%,职业高中学生为60.52%,差异有统计学意义(χ²=87.28,P＜0.01)。结论 黟县中学生艾滋病防治知识知晓率偏低,干预后得以明显提高。相关部门应进一步加强对中学生艾滋病防治知识的健康教育,特别是以乡镇初中学生及职业高中学生为重点,加大艾滋病防治知识的宣传教育力度,提高中学生对艾滋病防治知识知晓水平。

The difference of awareness rate of AIDS prevention and control among the subjects before and after intervention was analyzed, and the effect of intervention was evaluated. Results The awareness rate of AIDS prevention and control among 697 students before intervention was 73.31%, which was increased to 96.42% at the end of the intervention, and after intervention for 2 weeks was about 95.18%, and the difference was statistically significant (χ²=1780, P＜0.01). Before intervention, the awareness rate of AIDS prevention and control among senior high school students was significantly higher than that of junior high school students, and the difference was statistically significant (χ²=20.47, P＜0.01). Awareness of AIDS prevention and control knowledge of junior high school students in urban areas was 76.88%, of township junior high school students was 65.79%, and the difference was statistically significant (χ²=44.67, P＜0.01). The knowledge of AIDS prevention and control in general high school students was 80.36%, in vocational high school students was 60.52%, and the difference was statistically significant(χ²=87.28, P＜0.01). Conclusion The awareness rate of AIDS prevention and control among middle school students in Yixian County was low, which was significantly improved after intervention.
