All in the Family: Family Members Weight and Weight-Related Behaviors and Adoles

描述（由申请人提供）：摘要专家小组，研究人员和美国国立卫生研究院建议检查家庭环境中的多种家庭影响和人际关系，以确定儿童和青少年肥胖的可改变的风险和保护因素。这项研究的主要目的是研究多个家庭成员的体重和体重相关行为与青少年的体重指数（BMI）Z评分、超重状况、饮食摄入和体力活动之间的关系。这项研究将解决未回答的方法学问题，调查和干预的因素，可能会影响青少年肥胖的家庭环境。(1)首先，我们不知道父母在家庭中对待兄弟姐妹的方式是否相似（或不同），关于体重和与体重相关的行为。了解父母对兄弟姐妹的区别对待将告知是否需要针对家庭中不同儿童的肥胖预防干预措施。(2)其次，重要的是要确定谁包括在青少年肥胖干预;父母双方都应该包括在内，兄弟姐妹应该参与吗？了解哪些家庭成员的体重和体重相关行为与青少年的体重，饮食摄入量和身体活动的相关性更高，可以深入了解哪些家庭成员应该被纳入预防青少年肥胖的干预措施中。(3)第三，关于家庭对青少年肥胖的影响，一个关键的未回答的问题是，包括多个家庭成员对家庭环境的报告是否重要。例如，父亲或兄弟姐妹是否提供了关于家庭环境的独特信息，超出了目标儿童或母亲的报告？拟议的研究将通过使用两项NIH R 01研究（多水平、基于人群的研究）进行二级数据分析来回答这些重要问题。拟议的研究，所有在家庭中，将使用项目F-EAT（家庭和青少年饮食和活动）和EAT 2010（青少年饮食和活动）的数据子集，这些数据将父母/照顾者（监护人，非监护人，继父母）联系起来 其他照顾者（祖母，阿姨），青少年儿童和兄弟姐妹数据。总体数据集包括3，709名种族/种族和社会人口统计学上多样化的父母（62%为女性），2，793名青少年（53%为女性）和204名青少年兄弟姐妹（57%为女性）的子集。最初计划纳入兄弟姐妹数据，也没有在EAT 2010或F-EAT的原始研究目标中进行兄弟姐妹分析。因此，拟议的研究将通过分析兄弟姐妹的数据来确定家庭成员之间的二元和三元关系，并检查这些关系与青少年体重和体重相关结果之间的关联，从而独特地增加EAT 2010和F-EAT的结果。这一丰富的数据集将允许评估一个更复杂的家庭动态交互模型，该模型有助于青少年体重，饮食摄入量和身体活动，这将直接为制定更有效的以家庭为基础的青少年肥胖预防干预措施提供信息。

DESCRIPTION (provided by applicant): Abstract Expert panels, researchers and the NIH have recommended examining multiple familial influences and interpersonal relationships within the home environment in order to identify modifiable risk and protective factors for child and adolescent obesity. The main aim of the proposed study, all in the Family, is to examine the relationships between multiple family members' weight and weight-related behaviors and adolescents' body mass index (BMI) z-score, overweight status, dietary intake and physical activity. This study will address unanswered methodological questions relevant to investigating and intervening on factors that may influence adolescent obesity within the home environment. (1) First, it is unknown whether parents treat siblings within the home similarly (or differently) n regards to weight and weight-related behaviors. Knowledge about differential treatment of siblings by parents will inform whether obesity prevention interventions need to be tailored to different children within the home. (2) Second, it is important to determine who to include in adolescent obesity interventions; should both parents be included and should siblings be involved? Knowing which family members' weight and weight-related behaviors are more highly associated with adolescents' weight, dietary intake and physical activity may give insight into which family member(s) should be included in interventions to prevent adolescent obesity. (3) Third, a critical unanswered question in regards to familial influences on adolescent obesity is whether it is important to include multiple family members' reports of the home environment. For example, do the father or siblings provide unique information about the home environment above and beyond reports by the target child or the mother? The proposed study will answer these important questions by conducting a secondary data analysis using two NIH R01 studies that are multi-level, population-based studies. The proposed study, All in the Family, will use a subset of data from Project F-EAT (Families and Eating and Activity in Teens) and EAT 2010 (Eating and Activity in Teens), which link parent/caregiver (custodial, non-custodial, step-parent) other caregivers (grandmother, aunt), adolescent child, and sibling data. The overall dataset includes 3,709 ethnically/racially and socio-demographically diverse parents (62% female), 2,793 adolescents (53% female), and a subset of 204 adolescent siblings (57% female).The inclusion of sibling data was not originally planned, nor were analyses regarding siblings addressed in the original study aims for EAT 2010 or F-EAT. Thus, the proposed study will uniquely add to the results from EAT 2010 and F-EAT by analyzing data from siblings to identify dyadic and triadic relationships between family members and examining the association between these relationships with adolescent weight and weight-related outcomes. This rich dataset will allow for the evaluation of a more complex interactive model of the familial dynamics contributing to adolescent weight, dietary intake and physical activity that will directly inform te development of more effective family-based adolescent obesity prevention interventions.
