上海市高中生预防艾滋病同伴教育随访研究

Follow-up study of peer education program on HIV/AIDS among senior high school students in Shanghai

目的评价对高中生进行预防艾滋病同伴教育的效果。方法采用随机数字表法,从上海市虹口区的高级中学中随机抽取3所学校作为样本学校。从每所样本学校中随机抽取一个班级共143人作为干预组,另自每所样本学校中各抽取一个班级共152人作为对照组。对干预组学生实施6个学时的艾滋病同伴教育,于同伴教育实施前及实施后1周和1年时,分别进行内容一致的问卷调查,内容涉及生殖健康、艾滋病和性病知识。结果干预组同伴教育实施前及实施后1周和1年的知识均分分别为21.66±8.71、31.72±7.78和30.97±8.46;对照组相应时间点的知识均分分别为22.32±9.24、22.61±8.66和22.51±9.16。统计学分析表明,同伴教育实施前干预组与对照组的知识均分比较差异无统计学意义(P>0.05);干预组同伴教育实施后1周和1年的知识均分较教育实施前及相应时间点的对照组明显提高,差异均有统计学意义(P<0.001);干预组教育实施后两时间点间以及对照组不同时间点间的知识均分比较,差异均无统计学差异(P>0.05)。结论预防艾滋病同伴教育能显著提高高中生的相关知识水平,且具有长效性的特点。

Objective To evaluate the effects of peer education program on HIV/AIDS prevention among senior high school students. Methods Three senior high schools were randomly selected from Hongkou District of Shanghai as sample schools. One hundred and forty-three students from one class of each school were randomly selected as intervention group,and 152 students from another class of each school were served as control group. Six class hours of peer education program on HIV/AIDS prevention were conducted among intervention group. The same questionnaires which contained knowledge of reproductive health,HIV/AIDS and sexually transmitted diseases were administered before the program,one week and one year after the program. Results The knowledge scores before the program,one week and one year after the program in intervention group were 21.66±8.71,31.72±7.78 and 30.97±8.46,respectively,and those in control group were 22.32±9.24,22.61±8.66 and 22.51±9.16,respectively. There was no significant difference in the knowledge scores before the program between intervention group and control group,while there were significant differences in the knowledge scores one week and one year after the program between intervention group and control group （P〈0.001）. There were significant differences between the knowledge scores of one week and one year after the program and that before the program in intervention group （P〈0.001）,while there was no significant difference between the knowledge score of one week after the program and that of one year after the program. Besides,no significant changes in the knowledge scores were found in control group.Conclusion Peer education program on HIV/AIDS prevention can significantly promote the related knowledge level and the effects can maintain a long time.
