目的：为了确定是否青少年的规范信念禁欲和避孕套，他们的个人风险认知，和更安全的性行为改变后，实施同伴的性健康教育干预实施在赞比亚secondaryschools.Methods：同伴干预实施在2000年9月的第一个星期在卢萨卡，赞比亚。一个准实验，纵向面板设计被用来评估其影响。三所学校被随机分配到干预条件和两个控制条件。在2000年7月的基线、2000年9月下半月的第一次随访和2001年4月初的第二次随访时，收集了10年级和11年级男女青少年的三轮数据。在所有三轮调查中，共有416名年龄在14-23岁（基线）的受访者接受了采访。一个混合效应的Logistic回归增长曲线分析被用来计算调整后的优势比，比较干预和对照组的结果variable.Results：学生自我报告显示积极的变化，规范的信念禁欲后立即干预，这些改善主要持续到6个月后的干预。学生变得更有可能批准使用避孕套，并打算使用避孕套后立即干预，但这些积极的结果不能持续在6个月的干预。关于安全套使用的规范信念需要更长的时间才能形成：这些仅在6个月随访时观察到。学生们报告说，多个定期伙伴关系减少。避孕套的使用没有变化。结论：一个单一的会议学校为基础的同伴性健康干预导致发展的规范信念禁欲，持续了6个月的时间。关于避孕套的规范性信念需要更长的时间才能形成。可能需要作出更经常的努力，以维持对避孕套的批准和使用避孕套的意愿。这一干预措施成功地减少了多重定期伙伴关系。(C)青少年医学协会，2004年
Purpose: To determine whether adolescents' normative beliefs about abstinence and condoms, their personal risk perception, and safer sex practices changed after the implementation of a peer sexual health education intervention implemented in Zambian secondary schools.Methods: The peer intervention was implemented during the first week of September 2000 in Lusaka, Zambia. A quasi-experimental, longitudinal panel design was used to evaluate its impact. Three schools were randomly assigned to the intervention condition and two to the control condition. Three rounds of data from male and female adolescents in grades 10 and 11 were collected at baseline in July 2000, at first follow-up in the second half of September 2000, and at second follow-up in early April 2001. A total of 416 respondents aged 14-23 (at baseline) were interviewed in all three survey rounds. A mixed-effects logistic regression growth curve analysis was used to calculate adjusted odds ratios to compare intervention and control groups on the outcome variables.Results: Student self-reports showed positive changes in normative beliefs about abstinence immediately after the intervention, and these improvements were largely sustained until 6 months after the intervention. Students became more likely to approve of condom use and to intend using condoms immediately after the intervention, but these positive outcomes could not be sustained during the 6 months that followed the intervention. Normative beliefs regarding condom use took longer to develop: these were only observed at 6 months follow-up. Students reported reductions in multiple regular partnerships. There was no change in condom use.Conclusions: A single session school-based peer sexual health intervention resulted in the development of normative beliefs about abstinence that were sustained over a 6-month period. Normative beliefs about condoms took longer to develop. More regular efforts may be required to sustain the approval of, and the intention to use, condoms. The intervention was successful in reducing multiple regular partnerships. (C) Society for Adolescent Medicine, 2004
