THE AMERICAN TEENAGE STUDY

我们建议进行一项全国性的调查， 美国7到11年级的青少年男女。S.研究 使青少年处于危险之中的行为模式和决定因素 艾滋病，其他性病和怀孕。 样本将从一个 以200为概率抽样，对所有在校学生进行校内筛查 包含这些等级的学校。 受访者将接受两次采访 访谈之间间隔18个月。 小学生行为 兴趣是性、避孕和预防行为， 静脉注射毒品 行为决定因素将在几个方面进行衡量 不同的概念层次：社区，学校，同龄人，朋友， 家庭和个人。 收集数据的目的是最大限度地 符合艾滋病流行病学模型的需要。 分析 将利用我们识别性接触网络的独特能力 以及具有不同风险结构的人群的混合。 技术 对于面板数据的分析将允许实施可信的因果关系， 模型 项目的最终目标是：（1）了解艾滋病风险 在更广泛的社会背景下发生的行为，以及（2） 生成数据以预测艾滋病在青少年中的传播 人口

We propose a nationally representative survey of more than 20,000 adolescent males and females in grades 7 through 11 in the U. S. to study the patterns and determinants of behaviors which put adolescents at risk of AIDS, other STDs and pregnancy. The sample will be selected from an in-school screening of all pupils attending a probability sample of 200 schools containing these grades. Respondents will be interviewed twice with an interval of 18 months between interviews. Behaviors of primary interest are sexual, contraceptive, and prophylactic behavior and intravenous drug use. Behavior determinants will be measured at several different conceptual levels: community, school, peer group, friends, family, and individual. Data are to be collected so as to maximize their fit to the needs of epidemiological models for the AIDS epidemic. Analysis will capitalize on our unique ability to identify sexual contact networks and the mixing of populations with different risk structures. Techniques for the analysis of panel data will allow implementation of credible causal models. The ultimate goal of the project are: (1) to understand AIDS risk behaviors in the broader social context within which they occur, and (2) generate data to be able to predict the spread of AIDS in the adolescent population.
