摘　　要：目的评价性与生殖健康社区干预项目对未婚年轻人性行为发生的长期影响。方法在上海市郊两个镇开展以社区为基础的干预研究,干预持续20个月,干预活动包括性与生殖健康知识教育、咨询及避孕服务。通过干预前、干预结束时及干预结束28个月后3次问卷调查评价干预项目的长期影响。结果从第3次调查所有对象性行为的发生情况看,干预组中学生性行为发生比例低于对照组,但经多因素分析调整了可能的影响因素后发现,干预对不同类别对象的性行为发生均无长期影响。从第3次调查原干预队列对象研究期间性行为的发生情况看,剔除基线调查时有过性行为的对象后,干预结束时中学生性行为的发生比例干预组低于对照组,但第3次调查两组不同类别对象性行为发生比例无统计学差别。多因素分析调整了可能的影响因素后也未发现干预对不同类别对象随访期间性行为的发生有持续作用。从新对象性行为的发生情况看,干预组不同类别对象性行为发生比例均明显低于对照组,但经多因素分析调整了可能的影响因素后发现,干预对不同类别新对象的性行为发生均无延续影响。结论干预项目对未婚年轻人性行为发生的长期影响不明显,其主要原因可能与干预结束后干预组社区性教育活动明显减弱、而对照组也在社区开展了类似活动以及当地存在订婚后同居的习俗有关。Purpose To evaluate the long-term effectiveness of a community-based sex and reproductive health education and services program on unmarried youth＇s sexual behavior. Methods Two towns in sub-urban Shanghai were selected as the study sites. The intervention lasted 20 months and comprised 3 main areas of activities, i.e. building awareness, offering counseling and contraceptive services. The longer-term effectiveness of the program was evaluated by comparing the results from the follow-up survey conducted 28 months after the completion of the intervention with those from the baseline and post-intervention surveys. Results Among all respondents interviewed in the third survey, middle school students in the intervention group were less likely to have sexual behavior than those in the control group. However, the difference was no longer found after adjusting possible influence factors, indicating the intervention had no long-term effect on sexual behavior among all respondents. Among old respondents who had no sexual experience at baseline survey, middle school students in the intervention group were less likely to have sexual behavior than those in the control group at post-intervention survey. However, the differences of sexual behavior between the two groups among different types of subjects were not statistically significant at follow-up survey. After adjusting possible influence factors, the intervention still had no long-term effectiveness on sexual behavior among different types of old respondents. Among new respondents, subjects of different types in the intervention group were less likely to have sexual behavior than those in the control group. However, the differences were no longer found after adjusting possible influence factors. Conclusions Community-based sex and reproductive health education and services had no long-term effectiveness on sexual behavior among unmarried young people. The main reasons might be that sex education activities were weakened obviously in the intervention group, while similar
