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

描述（由申请人提供）：项目摘要/摘要健康通道是一项关于青少年健康的三个地点的纵向研究，重点是风险和保护因素，健康行为（例如，饮食习惯、缺乏身体活动、烟草使用和暴力活动），以及健康结果（例如，糖尿病、肥胖症和性传播疾病）的五年级队列研究，从10岁到20岁每两年进行一次随访。健康通道旨在以多种方式促进儿童和青少年健康的研究文献。它收集关于广泛结果的数据和一套全面、多层次的因素（例如，生物学、家庭、同伴、学校和邻里）作为健康风险和保护行为随时间的发生、维持和变化的预测因子。此外，健康通道提供了两年一次的深入评估5，147青年（和他们的主要照顾者）多年来（从五年级到高中后两年），以收集所需的数据来描述对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。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，使用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选择并招募5，147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的样本量足够，以支持精确的统计推断。数据收集工作于2004年开始，计划持续10年（可能更长）。第一波（5级）和第二波（7级）的数据收集工作已在上一个5年供资周期完成。第三波（10年级）面试于2010年1月开始，对前半期学生进行。 为了完成下一阶段的纵向研究，我们目前正在寻求资金，以便从2010年9月到2015年9月在洛杉矶继续进行五年的健康通道。该项目的未来五年将致力于完成第三波（10年级），第4波（12年级）和Wave 5（高中后一年）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Waves 4 - 5及以后的测量开发和规划。

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.
