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

健康通道是一项针对青少年健康的三站点纵向研究，重点关注风险和保护因素、健康行为（如饮食习惯、缺乏体育锻炼、吸烟和暴力活动）和健康结果（如糖尿病、肥胖和性传播疾病），对五年级队列进行两年一次的随访，从10岁到20岁。健康通道旨在以几种方式推进儿童和青少年健康的研究文献。它收集了广泛的结果和一套全面的、多层次的因素（例如，生物、家庭、同伴、学校和社区）的数据，作为健康风险和保护行为的发生、维持和变化的预测因素。此外，“健康通道”对5147名青少年（及其主要照顾者）进行了两年一次的深度评估（从五年级到高中毕业后两年），以收集表征青少年健康风险和保护行为以及健康和教育成果的主要影响所需的数据。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，以促进青少年和年轻人的健康和最佳发展。为了实现该项目的目标，采用了两阶段概率抽样程序，从阿拉巴马州伯明翰、德克萨斯州休斯顿和加利福尼亚州洛杉矶的学校中选择并招收了5147名五年级学生，以确保非洲裔美国人、西班牙裔美国人和非西班牙裔白人有足够的样本量，以支持精确的统计推断。数据收集始于2004年，计划持续10年（可能更长）。第一阶段（五年级）和第二阶段（七年级）的数据收集工作在上一个五年资助周期内完成。第三轮（10年级）面试于2010年1月开始，面试对象是前一半的学生。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，在洛杉矶继续开展健康通道研究五年。未来五年的项目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，准备演讲，传播研究结果；以及4 - 5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.
