DESCRIPTION (provided by applicant): Over 34% of adolescents are overweight or obese. Observational research suggests that family behaviors, such as family meals or parental role modeling, may play an important role in shaping adolescent behaviors and resulting weight status. However, results are not consistent across studies. Family systems theory asserts that family behaviors must be understood within the global family context. Global family factors, such as parent-child relationship quality or general family functioning, influence how family behaviors are experienced by the adolescents. Thus these factors may be potentially powerful modifiers of the associations between family behaviors and adolescent outcomes. Omitting the family context within which these family behaviors occur may explain the inconsistent research findings. We propose to address this fundamental gap by conducting a large cohort study to determine how specific global family factors influence associations between family behaviors and adolescent weight-related outcomes. The overall objective of this proposal is to examine independent and interactive associations of family behaviors and global family factors with adolescent weight and with weight-related behaviors. To achieve this objective, we will use longitudinal repeated measures data and newly collected survey data from the Growing Up Today Study 2 (GUTS2), an ongoing cohort study of adolescents. We will link adolescents' data to data from their mothers, who are participants in the Nurses' Health Study 2. The proposed study's large size (n=10,442), prospective design, basis in sound behavior theory, and multi-level data on mothers and adolescents provide an unsurpassed opportunity to study the influence of the family context on adolescent weight and weight-related behaviors. Results of this study will provide a much-needed basis for effective family-based obesity prevention interventions.

描述（由申请人提供）：超过 34% 的青少年超重或肥胖。观察研究表明，家庭行为，例如家庭聚餐或父母的榜样，可能在塑造青少年行为和由此产生的体重状况方面发挥重要作用。然而，各项研究的结果并不一致。家庭系统理论主张，必须在全球家庭背景下理解家庭行为。全球家庭因素，例如亲子关系质量或一般家庭功能，影响青少年对家庭行为的体验。因此，这些因素可能是家庭行为与青少年结果之间关联的潜在强大调节因素。忽略这些家庭行为发生的家庭背景可能可以解释不一致的研究结果。我们建议通过开展一项大型队列研究来解决这一根本差距，以确定特定的全球家庭因素如何影响家庭行为与青少年体重相关结果之间的关联。该提案的总体目标是检查家庭行为和全球家庭因素与青少年体重和体重相关行为之间的独立和交互关联。为了实现这一目标，我们将使用纵向重复测量数据和来自“今日成长研究 2”(GUTS2)（一项正在进行的青少年队列研究）新收集的调查数据。我们将把青少年的数据与参加护士健康研究 2 的母亲的数据联系起来。拟议的研究规模大（n=10,442）、前瞻性设计、健全的行为理论基础以及关于母亲和青少年的多层次数据为研究家庭环境对青少年体重和体重相关行为的影响提供了无与伦比的机会。这项研究的结果将为有效的基于家庭的肥胖预防干预措施提供急需的基础。
