目的：衡量以学校为基础的人类免疫缺陷病毒（HIV）、性传播疾病（STD）和预防怀孕干预对不同亚组学生性冒险行为的相对影响。方法：随机分配20所学校接受“更安全的选择”或标准的基于知识的艾滋病毒教育计划。“更安全的选择”旨在通过推迟性行为的开始、减少其频率或增加避孕套的使用来减少无保护的性行为。它的五个组成部分包括：学校组织、强化课程与员工发展、同伴资源和学校环境、家长教育和学校与社区的联系。共对3869名九年级学生进行了31个月的跟踪调查。调查结果包括性行为的开始、无保护的性行为频率、无保护的性伴侣数量、避孕套的使用和避孕药具的使用。这些结果是根据性别、种族/民族、先前的性经历和先前的性冒险分别呈现的。统计分析包括多水平、重复测量、逻辑回归和泊松回归模型。结果：更安全的选择对所有亚组都有一个或多个积极的行为影响。在使用避孕套可能影响的四项结果中，它对男性的影响大于对女性的影响。与其他种族/民族相比，它对西班牙裔的影响更大，包括性行为的延迟。其最大的总体效果是在干预前进行过无保护性行为的学生中避孕套使用的增加。结论：“更安全的选择”在31个月内降低了所有青少年群体的一项或多项性风险措施，对男性、西班牙裔和从事无保护性行为的青少年尤其有效，这些人群感染艾滋病毒、其他性病和怀孕的风险较高。(C)青少年医学协会，2004年。
Purpose: To measure the relative impact of a schoolbased human immunodeficiency virus (HIV)-, sexually transmitted disease (STD)-, and pregnancy-prevention intervention on sexual risk-taking behaviors of different subgroups of students.Methods: Twenty schools were randomly assigned to receive Safer Choices or a standard knowledge-based HIV-education program. Safer Choices was designed to reduce unprotected sex by delaying initiation of sex, reducing its frequency, or increasing condom use. Its five components included: school organization, an intensive curriculum with staff development, peer resources and school environment, parent education, and school-community linkages. A total of 3869 9th-grade students were tracked for 31 months. Results are presented for initiation of sex, frequency of unprotected sex, number of unprotected sexual partners, condom use, and contraceptive use. These results are presented separately by gender, race/ethnicity, prior sexual experience, and prior sexual risk-taking. Statistical analyses included multilevel, repeated measures logistic and Poisson regression models.Results: Safer Choices had one or more positive behavioral effects on all subgroups. On four outcomes that could be affected by condom use, it had a greater impact on males than on females. It had greater effects on Hispanics, including a delay in sexual activity, than on other racial/ethnic groups. Its greatest overall effect was an increase in condom use among students who had engaged in unprotected sex before the intervention.Conclusions: Safer Choices reduced one or more measures of sexual risk taking over 31 months among all groups of youth, and was especially effective with males, Hispanics, and youth who engaged in unprotected sex and thus were at higher risk for HIV, other STD infections and pregnancy.
