EAT 2010-2018: A Longitudinal, Multi-Contextual Study of Weight-related Problems

 描述（由申请人提供）：与体重相关的问题，包括肥胖、不良饮食行为、体力活动不足、不健康的体重控制习惯和身体不满，在年轻人中非常普遍，并产生不良的身体和心理社会后果。肥胖是当今社会最重要的公共卫生问题之一。美国国立卫生研究院和著名的研究人员呼吁进行纵向研究，研究可能影响肥胖和其他体重相关问题的多种环境。拟议中的研究，“EAT 2010-2018：一项关于体重相关问题的纵向、多背景研究”，是对这些呼吁的回应。本研究的主要目的是确定一个不同的人口为基础的样本的年轻人，因为他们从青春期过渡到年轻的成年人的体重相关的问题的纵向，多背景的预测。为了实现这一目标，拟议的研究建立在现有的数据收集的2,793名青少年在EAT 2010年的一部分，以前资助的R 01研究。研究人群包括高比例的少数民族/种族（82%）和低收入背景的年轻人（基线时有71%的人有资格获得免费/降价的学校餐），他们有很高的肥胖风险。2010年，还收集了这些青少年的父母、朋友、学校和社区的横截面数据。在拟议的研究中，将从原始研究参与者（现在是年轻人）及其父母、朋友和重要他人那里收集随访数据。此外，还将收集有关年轻人的学校/工作场所和社区环境的数据。这项纵向研究将允许检查多个因素如何预测不同的年轻人在关键的生命历程过渡期间，包括新的友谊，学校，生活安排，角色和责任，与体重相关的结果的变化。纳入直接从母亲和父亲或其他相关照顾者那里收集的纵向数据，将有助于解决尚未回答的问题，即父母如何能够以发展适当的方式帮助青少年和年轻成年子女解决与体重有关的问题，因为他们变得更加独立。创新的研究方法将被用来调查研究参与者目前的朋友和重要的其他人，并探索早期，持续和目前的友谊对体重相关结果的潜在影响。关于家庭、朋友、学校/工作场所和邻里环境等领域的因素以及它们与体重相关结果的相关性，还有很多东西需要了解。这项全面的纵向研究将解决新的研究问题，这些问题已经成为理解年轻人体重相关问题病因的关键。研究结果将指导制定更具创新性和有效的干预措施，针对多种影响环境，以预防和治疗来自不同种族/种族和社会经济背景的青少年和年轻人的广泛体重相关问题。

 DESCRIPTION (provided by applicant): Weight-related problems including obesity, poor eating behaviors, inadequate physical activity, unhealthy weight control practices, and body dissatisfaction are very prevalent among young adults, and have adverse physical and psychosocial consequences. Obesity is one of the most significant public health problems in today's society. NIH and prominent researchers have called for longitudinal research that examines multiple environments with the potential to influence obesity and other weight-related problems. The proposed study, "EAT 2010-2018: A longitudinal, multi-contextual study of weight-related problems," is responsive to these calls. The primary aim of this study is to identif longitudinal, multi-contextual predictors of weight-related problems in a diverse population-based sample of young people as they transition from adolescence to young adulthood. To accomplish this aim, the proposed study builds upon existing data collected on 2,793 adolescents in EAT 2010 as part of a previously funded R01 study. The study population includes a high percentage of young people from ethnic/racial minority (82%) and low-income backgrounds (71% qualified for free/reduced price school meals at baseline) who are at high risk for obesity. In 2010, cross-sectional data were also collected on these adolescents' mothers and fathers, friends, schools, and neighborhoods. In the proposed study, follow-up data will be collected from the original study participants, who are now young adults, and their parents, friends, and significant others. Additionally, data will be collected on the young adults' school/workplace and neighborhood environments. This longitudinal study will allow for an examination of how multiple factors predict changes in weight-related outcomes among diverse young people during key life course transitions involving new friendships, schools, living arrangements, roles, and responsibilities. The inclusion of longitudinal data collected directly from both mothers and fathers, or other caregivers as relevant, will help address unanswered questions about how parents can best help their adolescent and young adult children with weight-related problems, in a developmentally appropriate way, as they become more independent. Innovative research methodologies will be utilized to survey current friends and significant others of study participants and explore the potential impact of earlier, ongoing, and current friendships on weight- related outcomes over time. There is much to be learned about factors from within the domains of family, friend, school/workplace, and neighborhood environments and their relevance for weight-related outcomes. This comprehensive, longitudinal study will address new research questions that have emerged as key to understanding the etiology of weight-related problems in young people. Findings will guide the development of more innovative and effective interventions that target multiple environments of influence to prevent and treat a broad spectrum of weight-related problems in adolescents and young adults from diverse ethnic/racial and socio-economic backgrounds.
