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不满，也令人关切，因为它们对健康造成不利影响。需要有关这些问题的长期轨迹、代代相传以及风险和保护因素的信息，以指导公共卫生干预措施。提出的纵向研究，EAT-IV项目（青少年和年轻人的饮食和活动），建立在之前的研究浪潮的基础上，这些研究是在10年的时间里收集的数据，这些数据来自一个不同人群的队列，从青春期的不同阶段到刚进入成年期。EAT-IV项目将对研究参与者进行为期15年的随访（1999-2014），从青春期（12-18岁）到青年期（27-33岁）。数据将从大约2250名来自不同民族/种族和社会经济背景的年轻人中收集，他们参加了之前的研究浪潮。此外，第一次：1)数据将在适用的情况下从参与者的重要他人那里收集（预计会有）
