DESCRIPTION (provided by applicant): An alarming increase in pediatric obesity has occurred in China, a developing country undergoing rapid economic transition. The prevalence was even higher in the developed metropolitan areas of China. The dramatic increase in the prevalence of obesity in children and adolescents has raised major concerns due to the long-term health implications. Pediatric obesity may increase morbidity as well as susceptibility to certain cancers in later life. Efforts to prevent obesity and maintain a healthy body weight has been recognized as one of most cost-effective long-term strategies for cancer control. Parents and the family environment play an important role in influencing adolescents' adoption and maintenance of healthy weight-related behaviors that regulate energy balance and ultimately obesity status. Certain characteristics of parenting styles, practices and family functioning may be influential in the development of obesity among adolescents. Even though some empirical studies, most with cross-sectional study designs, have provided preliminary data, there is an urgent need for rigorous investigations with longitudinal data for an improved understanding of these familial and parental characteristics and their roles in influencing management of weight-related behaviors and the risks of obesity in adolescents. There is a lack of research investigating the dynamic reciprocal relationships between multiple aspects of family functioning and obesity and related behaviors in adolescent populations. As obesity is not as widespread in China but is rapidly increasing, it is possible to study an epidemic of obesity in its earlier stags along with rapid social and economic development and the role of family relations in the process. We propose to systematically investigate longitudinal dynamic influences of critical parental and familial factors on adolescents' developmental risks of behavioral outcomes including obesity, eating behaviors and food consumption, physical activity and inactivity, and depressive symptoms with two existing longitudinal cohort datasets collected in representative samples of Chinese adolescents living in several major large cities in China. State of the art modeling approaches will be applied to analyze influence of family functioning and parenting characteristics in the developmental risks of behavioral outcomes and model the dynamic reciprocal relationships between family functioning and behavioral outcomes that may be both causes and consequences of each other during a certain longitudinal period. Potential interactive effects of parenting characteristics and family functioning as well as the potentially differential influences across parent-child gender will be explored to advance understanding of the heterogeneity of longitudinal familial and parental influences on the developmental risks of obesity and related behavioral outcomes. Findings of this study are expected to have the great potential to advance knowledge on the influences of parental and familial factors on the developmental risks of obesity and related behaviors during adolescence, which may guide to translate into the development of appropriate interventions as long-term strategies for cancer prevention and control.

描述（由申请人提供）：中国这个正在经历快速经济转型的发展中国家，儿童肥胖症的发病率惊人地增加。在中国发达的大都市地区，患病率甚至更高。儿童和青少年肥胖患病率的急剧上升因其对健康的长期影响而引起了人们的重大关注。儿童肥胖可能会增加以后生活中某些癌症的发病率和易感性。预防肥胖和保持健康体重的努力已被认为是控制癌症最具成本效益的长期策略之一。父母和家庭环境在影响青少年采取和维持与体重相关的健康行为方面发挥着重要作用，这些行为调节能量平衡并最终调节肥胖状态。养育方式、做法和家庭功能的某些特征可能会影响青少年肥胖的发生。尽管一些实证研究（大多数采用横断面研究设计）提供了初步数据，但仍迫切需要对纵向数据进行严格调查，以更好地了解这些家庭和父母特征及其在影响体重相关行为管理和青少年肥胖风险方面的作用。缺乏研究调查家庭功能的多个方面与青少年群体肥胖及相关行为之间的动态相互关系。由于肥胖在中国并不普遍，但正在迅速增加，因此可以研究肥胖流行的早期阶段以及社会和经济的快速发展以及家庭关系在这一过程中的作用。我们建议利用从居住在中国几个主要大城市的中国青少年代表性样本中收集的两个现有纵向队列数据集，系统地研究关键父母和家庭因素对青少年行为结果发育风险的纵向动态影响，包括肥胖、饮食行为和食物消耗、体力活动和不活动以及抑郁症状。最先进的建模方法将用于分析家庭功能和养育特征对行为结果的发展风险的影响，并对家庭功能和行为结果之间的动态相互关系进行建模，这些关系在一定的纵向时期内可能是彼此的原因和结果。将探讨养育特征和家庭功能的潜在相互作用效应以及亲子性别之间的潜在差异影响，以增进对纵向家庭和父母影响对肥胖和相关行为结果的发育风险的异质性的理解。这项研究的结果预计将具有巨大的潜力，可以增进人们对父母和家庭因素对青春期肥胖和相关行为的发育风险的影响的了解，这可能会指导转化为适当干预措施的制定，作为癌症预防和控制的长期策略。
