项目摘要

DESCRIPTION (provided by applicant): Poor eating behaviors, inadequate physical activity, and obesity are some of the most pressing public health problems facing youth and adults in the United States. Other weight-related problems, including unhealthy weight control practices and body dissatisfaction, are also of concern given their adverse health consequences. Information on trajectories of these problems over time, their transmission from one generation to the next, and risk and protective factors, is needed to guide public health interventions. The proposed longitudinal study, Project EAT-IV (Eating and Activity in Teens and Young Adults), builds on previous study waves in which data were collected over a 10-year period on a diverse population-based cohort throughout different stages of adolescence and into emerging young adulthood. Project EAT-IV will extend the follow-up of study participants to a 15-year period (1999-2014), from adolescence (ages 12-18) to young adulthood (ages 27-33). Data will be collected from approximately 2250 young adults representing diverse ethnic/racial and socioeconomic backgrounds, who participated in previous study waves. Additionally, for the first time: 1) data will be collected from participants' significant others when applicable (expected n � 1100); 2) parenting practices will be assessed among participants who have children (expected n � 1240); and 3) preadolescent (ages 9-11) and adolescent (ages 12-18) children of participants (expected n � 340) will be recruited into the study and asked about their eating behaviors, physical activity, and weight-related problems. The main study aim is to longitudinally examine eating behaviors, activity patterns, and weight-related problems, along with individual and socio-environmental predictors of these outcomes, over the life course from adolescence to young adulthood and across generations. Key research questions include: 1. How do eating behaviors, physical activity patterns, and weight-related problems track over a 15-year period (1999-2014) in a diverse sample, beginning in adolescence and continuing through young adulthood? What individual-level and socio-environmental factors, throughout the life course from adolescence to young adulthood, predict these outcomes in young adults and influence their trajectories over time? 2. How do eating behaviors, physical activity patterns, and weight-related problems during adolescence, and relevant individual-level and socio-environmental factors in adolescence, predict young adults' parenting practices regarding eating, activity, and weight? What are the implications for their children, the next generation of youth? What factors in young adulthood modify the strength of these associations? Important and timely questions related to obesity and other weight-related problems across key developmental transitions throughout the life course will be addressed using innovative and longitudinal research strategies. Findings will be widely disseminated to guide the development of interventions, practices, and policies to improve the weight-related health of young adults and their children.

描述（由申请人提供）：不良的饮食行为，身体活动不足和肥胖是美国青少年和成年人面临的一些最紧迫的公共卫生问题。其他与体重有关的问题，包括不健康的体重控制做法和对身体的不满，也令人关切，因为它们对健康产生不利影响。需要了解这些问题随时间推移的发展轨迹、代代相传的情况以及风险和保护因素，以指导公共卫生干预措施。拟议的纵向研究，EAT-IV项目（青少年和年轻人的饮食和活动），建立在以前的研究浪潮的基础上，在10年的时间内收集了一个基于不同人群的队列的数据，这些队列贯穿青春期的不同阶段，并进入成年初期。EAT-IV项目将对研究参与者的随访延长至15年（1999-2014年），从青少年（12-18岁）到青年（27-33岁）。将从约2250名代表不同种族/种族和社会经济背景的年轻人中收集数据，这些人参加了之前的研究浪潮。此外，第一次：1）数据将从参与者的重要他人那里收集（预期n）。 1100）; 2）在有孩子的参与者（预计n = 1240）中评估父母的做法; 3）参与者（预计n = 340）的青春期前（9-11岁）和青春期（12-18岁）的孩子将被招募到研究中，并询问他们的饮食行为，体育活动和体重相关问题。主要研究目的是纵向研究饮食行为，活动模式和体重相关问题，沿着这些结果的个人和社会环境预测因素，从青春期到青年期和跨代的生命过程。主要研究问题包括：1.饮食行为、身体活动模式和体重相关问题如何在15年（1999-2014）的不同样本中追踪，从青春期开始，一直持续到成年早期？在从青春期到青年期的整个生命过程中，哪些个人层面和社会环境因素可以预测年轻人的这些结果并影响他们随着时间的推移的轨迹？2.青少年时期的饮食行为、身体活动模式和体重相关问题，以及青少年时期相关的个人水平和社会环境因素，如何预测年轻人在饮食、活动和体重方面的父母行为？对他们的孩子，下一代青年有什么影响？在青年时期，哪些因素改变了这些联系的强度？与肥胖和其他体重相关的问题，在整个生命过程中的关键发展过渡的重要和及时的问题将得到解决，使用创新和纵向研究策略。调查结果将被广泛传播，以指导制定干预措施，实践和政策，以改善年轻人及其子女的体重相关健康。
