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（由适用提供）：饮食行为不佳，体育锻炼不足和肥胖是美国青年和成人面临的最紧迫的公共卫生问题。鉴于他们的不良健康后果，其他与体重有关的问题，包括不健康的体重控制实践和身体不满，也引起了人们的关注。需要有关这些问题的轨迹随着时间的流逝，它们从一代到第二代的传播以及风险和受保护因素的传播来指导公共卫生干预措施。拟议的纵向研究，即饮食IV（青少年和年轻人的饮食和活动），建立在先前的研究浪中，其中在10年内收集了数据，该数据是在跨青少年不同阶段的多样性基于人群的队列上，并进入了新兴的年轻成年。 EAT-IV项目将将研究参与者的随访扩展到15年（1999-2014），从青少年（12-18岁）到成年年轻（27-33岁）。数据将从代表潜水员/种族和社会经济背景的大约2250名年轻人中收集，他们参与了先前的研究浪潮。此外，第一次：1）在适用的情况下将从参与者的重要其他人那里收集数据（预期n€ 1100）; 2）将在有孩子的参与者中评估育儿惯例（预计n€1240）； 3）将招募参与者的儿童（预期n€340）（9-11岁）和青少年（12-18岁），并询问他们的饮食行为，体育活动和与体重相关的问题。主要研究的目的是纵向研究饮食行为，活动模式和与体重有关的问题，以及这些结果的个人和社会环境预测指标，从青春期到成年和各个世代的生活过程中。关键的研究问题包括：1。在15年期间（1999-2014）在潜水员样本中，饮食行为，体育锻炼模式和与体重有关的问题如何从青春期开始，一直持续到成年后？从青春期到年轻人的整个生活课程中，哪些个人水平和社会环境因素可以预测年轻人的这些结果并随着时间的推移影响其轨迹？ 2。青少年期间的饮食行为，体育锻炼模式和与体重相关的问题如何以及相关的个人水平和社会环境因素在青少年中预测年轻人成年人在饮食，活动和体重方面的育儿实践？对他们的孩子，下一代青年有什么影响？年轻成年中的哪些因素改变了这些关联的强度？与肥胖和重量相关的问题有关的重要和及时的问题将使用创新和纵向研究策略来解决整个生命过程中的关键发展过程中。调查结果将被广泛传播，以指导开发干预措施，做法和政策，以改善年轻人及其子女的体重相关健康。
