Healthy Passages II (Healthy Passages: A Longitudinal Study of Adolescent Health)

描述（由申请人提供）：健康通道研究项目是三个预防研究中心（UCLA/RAND，德克萨斯大学休斯顿分校和阿拉巴马大学伯明翰分校）和疾病预防控制中心之间的合作伙伴关系。1999年，美国疾病控制与预防中心最初通过合作协议为这三个地点提供资金，以发展健康通道，这是一项三地点纵向研究，为有效的政策和干预措施提供经验基础，以促进和维持青少年和成年人的健康和福祉。健康通道采用多层协议来评估生物学、家庭、同伴、学校和邻里/社区的影响，以确定如何最好地保持青少年的最佳健康。健康通道的总体目标是为有效的政策和干预方案提供经验基础，以促进青少年和成人的健康和最佳发展。这项研究有两个主要目标。第一个目标是描述发育轨迹（即个体内部随时间变化的模式）以及重要的多层次风险和保护因素（如家庭、同伴、学校和社区）对健康行为（如饮食习惯、体育活动、烟草使用）的相对贡献。例如，基于这种方法的社会政策影响可能产生更具成本效益和更全面的针对多种健康行为及其结果的干预措施。第二个目标是阐明造成不同种族/民族、性别和社会经济地位在健康、教育和社会结果方面存在差异的多重风险和保护因素（Levanthal， 2000年；Lowry， 1996年；Starfield， 2002年）。为了实现健康通道的目标，我们在伯明翰、休斯顿和洛杉矶连续招募了两组五年级学生。两个队列的第一波（五年级）和第二波（七年级）的数据收集已经完成。第三波（十年级），队列1的面试于2010年1月开始，将于2010年8月结束。我们目前正在寻求资金，从2010年9月到2015年9月，在伯明翰继续开展健康通道项目，为期五年。该项目未来五年将致力于实施第三波（10年级），第四波（12年级）和第五波（高中后一年）数据收集；跟踪登记的研究参与者，以保持调查期间最新的联系信息；继续进行科学监督、项目管理和社区合作；数据文件的整理、准备和管理；计算变量并进行统计分析；分析数据，撰写论文，准备报告；以及4 - 5波及以后的测量发展和规划。

DESCRIPTION (provided by applicant): The Healthy Passages research project functions as a collaborative partnership between three Prevention Research Centers (UCLA/RAND, University of Texas-Houston, and University of Alabama, Birmingham) and the CDC. In 1999, the three sites were initially funded by the CDC through cooperative agreements to develop Healthy Passages, a three-site longitudinal study to provide an empirical basis for effective policies and interventions to promote and maintain the health and well being of adolescents and adults. Healthy Passages employs a multilevel protocol to assess biological, family, peer, school, and neighborhood/community influences to determine how best to maintain the optimum health of youth. The overarching objective of Healthy Passages is to provide an empirical basis for effective policies and intervention programs to promote the health and optimal development of adolescents and adults. The study has two major goals. The first goal is the characterization of developmental trajectories (i.e., the patterns of intra-individual change across time) and the relative contribution of important multilevel risk and protective factors (e.g., family, peers, school, and community) on health behaviors (e.g., dietary practices, physical activity, tobacco use). Social policy implications based on such an approach may, for example, yield more cost-effective and encompassing interventions that target multiple health behaviors and their outcomes. The second goal is the elucidation of multilevel risk and protective factors that contribute to disparities in health, educational, and social outcomes by race/ethnicity, gender, and socioeconomic status (Levanthal, 2000; Lowry, 1996; Starfield, 2002). To accomplish the goals of Healthy Passages, we enrolled two successive cohorts of fifth grade students in Birmingham, Houston, and Los Angeles. Data collection for Wave 1 (fifth grade) and Wave 2 (seventh grade) has been completed for both cohorts. Interviewing for Wave 3 (tenth grade), cohort 1 began in January 2010 and will be completed by August 2010. We are currently seeking funding to continue Healthy Passages in the Birmingham site for five more years from September 2010 to September 2015. The next five years of the project will be devoted to implementation of the Wave 3 (10th grade), Wave 4 (12th grade), and Wave 5 (one year post-high school) data collection; tracking of enrolled study participants to maintain up-to-date contact information between survey waves; continued scientific oversight, program management, and community collaboration; cleaning, preparing and managing data files; computing variables and running statistical analyses; analyzing data, writing papers, and preparing presentations; and measurement development and planning for Waves 4 - 5 and beyond.
