Healthy Passages: A Long Term Follow-up Study of Adolescent Health

描述(由申请者提供)：项目摘要/摘要健康通道是一项关于青少年健康的三站点纵向研究，重点关注青少年健康的风险和保护因素、健康行为(例如饮食习惯、缺乏体育锻炼、吸烟和暴力活动)以及健康结果(例如糖尿病、肥胖症和性传播疾病)，从10岁到20岁每两年跟踪一次。《健康通道》旨在以几种方式推进有关儿童和青少年健康的研究文献。它收集关于广泛结果和一组全面的、多层次的因素(例如，生物、家庭、同伴、学校和邻居)的数据，以作为健康风险和保护行为随时间发生、维持和变化的预测因子。此外，健康通道每两年对5,147名青少年(及其主要照顾者)进行多年(从五年级到高中后两年)的深入评估，以收集必要的数据，以确定对青少年健康风险和保护行为以及健康和教育结果的主要影响。健康通道的首要目标是为有效的政策和干预计划提供经验基础，以促进青少年和年轻人的健康和最佳发展。为了实现该项目的目标，使用两阶段概率抽样程序从加利福尼亚州伯明翰、亚利桑那州、休斯敦、德克萨斯州和洛杉矶的学校挑选和招收5,147名五年级学生，以确保有足够的样本规模，包括非裔美国人、西班牙裔和非西班牙裔白人，以支持准确的统计推断。数据收集始于2004年，计划持续10年(可能还会更长)。第一波(5级)和2波(7级)的数据收集工作是在上一个5年供资周期内完成的。第三波(10年级)面试始于2010年1月，队列的前半部分。为了完成下一阶段的纵向研究，我们目前正在寻求资金，从2010年9月到2015年9月，在洛杉矶的网站上继续健康通道五年。该项目未来五年将致力于完成第三波(10年级)、第四波(12年级)和第五波(高中后一年)的数据收集；跟踪登记的研究参与者，以保持调查波之间的最新联系信息；持续的科学监督、项目管理和社区合作；清理、准备和管理数据文件；计算变量和运行统计分析；分析数据、撰写论文、准备演示文稿和传播结果；以及第四至第五波及以后的测量发展和规划。

DESCRIPTION (provided by applicant): Project Summary/Abstract Healthy Passages is a three site longitudinal study of adolescent health that focuses on risk and protective factors, health behaviors (e.g., dietary practices, physical inactivity, tobacco use, and violent activity), and health outcomes (e.g., diabetes, obesity, and sexually transmitted diseases) for a fifth grade cohort that is being followed biennially from ages 10 to 20 years. Healthy Passages is designed to advance the research literature on child and adolescent health in several ways. It collects data on a broad range of outcomes and a comprehensive, multilevel set of factors (e.g., biological, family, peer, school, and neighborhood) to function as predictors of the occurrence, maintenance, and change of health risk and protective behaviors across time. In addition, Healthy Passages provides biennial in-depth assessment of 5,147 youth (and their primary caregiver) over multiple years (from fifth grade through two years post high school) to collect data needed to characterize the primary influences on adolescent health risk and protective behaviors and health and educational outcomes. 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 young adults. To accomplish the project's goals, a two-staged probability sampling procedure was used to select and enroll 5,147 fifth grade students from schools in Birmingham, AL, Houston, TX, and Los Angeles, CA to ensure a sufficient sample size of African Americans, Hispanics, and non- Hispanic whites, to support precise statistical inferences. Data collection began in 2004 and is planned to continue for 10 years (and possibly beyond). Data collection for Wave 1 (grade 5) and Wave 2 (grade 7) was completed during the previous 5-year funding cycle. Wave 3 (grade 10) interviews began in January 2010 with the first half of the cohort. To complete the next stage of longitudinal research, we are currently seeking funding to continue Healthy Passages at the Los Angeles site for five more years from September 2010 to September 2015. The next five years of the project will be devoted to completing 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, preparing presentations, and disseminating findings; and measurement development and planning for Waves 4 - 5 and beyond.
