DESCRIPTION (provided by applicant): Childhood obesity is one of our nation's most significant public health problems. Hispanic youth are particularly at risk and are more likely to be overweight and obese than their non-Hispanic white counterparts partly because of their inadequate levels of physical activity and the poor quality of their dietary intake. Family functioning, specifically parental involvement and family communication, is related to a number of health behaviors and conditions, including drug use, tobacco use, sexual risk behaviors, physical activity, dietary intake, and body mass index (BMI). Despite the evidence that parental involvement and parent- adolescent communication have a role in obesity prevention, their incorporation into obesity prevention interventions has been limited. Thus, there is a critical need to develop family-based obesity preventive interventions for youth that target physical activity and poor diet, especially for Hispanic youth -- given the disproportionate and multiple obesity-related health burdens they face. Familias Unidas (United Families in English) is a family-based, culturally-specific intervention found to be efficacious in preventing or reducing a number negative health behaviors and conditions, including drug use, alcohol use, depression, sexual risk behaviors, conduct problems, sexually transmitted diseases, and alcohol dependence. Familias Unidas has impacted these outcomes through improvements in family functioning (e.g, parental involvement and parent-adolescent communication), the same mechanism that has been found to be related to physical activity and dietary intake. Preliminary data also indicate that Familias Unidas has positive effects on physical activity and that the effects of the intervention on physical activity are partially mediated by parental involvement. This study's aims are: AIM 1: To examine the relative efficacy of Familias Unidas, extended to target obesity, in increasing physical activity and improving the quality of dietary intake among overweight Hispanic youth and AIM 2: To examine whether and to what extent family functioning partially mediates the effects of Familias Unidas on physical activity and quality of dietary intake. To achieve these aims the proposed study will randomize 280 Hispanic youth to one of two conditions: 1) Familias Unidas or 2) a community practice control condition. Three study hypotheses will be tested: H1: Familias Unidas will be efficacious, compared to Community Practice, in increasing Hispanic youth's past seven day moderate to vigorous physical activity over time; H2: Familias Unidas will be efficacious, compared to Community Practice, in improving Hispanic youth's past seven day quality dietary intake (defined as decreases in sugar-sweetened beverages, decreases in intake of fast foods, and increases in fresh fruits and vegetables) over time; and H3: Familias Unidas' effects on youth's past day moderate to vigorous physical activity and youth's past seven day quality dietary intake will be partially mediated by changes in family functioning over time.

描述（由申请人提供）：儿童肥胖是我国最重要的公共卫生问题之一。西班牙裔年轻人比非西班牙裔白色年轻人面临的风险尤其大，更有可能超重和肥胖，部分原因是他们的身体活动水平不足，饮食摄入质量较差。家庭功能，特别是父母的参与和家庭沟通，与许多健康行为和状况有关，包括药物使用，烟草使用，性风险行为，身体活动，饮食摄入和体重指数（BMI）。尽管有证据表明父母的参与和父母与青少年的沟通在肥胖预防中发挥了作用，但将其纳入肥胖预防干预措施的程度有限。因此，迫切需要为青少年制定以家庭为基础的肥胖预防干预措施，针对体育活动和不良饮食，特别是西班牙裔青年-考虑到他们面临的不成比例和多种与肥胖相关的健康负担。Familias Unidas（英语：United Families in English）是一种以家庭为基础的、针对特定文化的干预措施，被发现在预防或减少一些负面健康行为和状况方面有效，包括吸毒、酗酒、抑郁、性风险行为、行为问题、性传播疾病和酒精依赖。家庭团结通过改善家庭功能（例如，父母参与和父母与青少年的沟通）影响了这些结果，这与发现与身体活动和饮食摄入有关的机制相同。初步数据还表明，Familias Unidas对身体活动有积极影响，干预对身体活动的影响部分是由父母参与介导的。这项研究的目的是：目标1：研究扩展到目标肥胖症的Familias Unidas在增加体力活动和改善超重西班牙裔青年饮食摄入质量方面的相对功效，目的2：研究家庭功能是否以及在多大程度上部分介导Familias Unidas对体力活动和饮食摄入质量的影响。为了实现这些目标，拟议的研究将280名西班牙裔青年随机分为两个条件之一：1）Familias Unidas或2）社区实践控制条件。将测试三个研究假设：H1：与社区实践相比，Familias Unidas将有效地增加西班牙裔青年过去七天的中度至剧烈体力活动; H2：与社区实践相比，Familias Unidas在改善西班牙裔青年过去七天的优质饮食摄入方面将是有效的（定义为含糖饮料减少，快餐摄入减少，新鲜水果和蔬菜增加）;以及H3：Familias Unidas对青少年过去一天中度到剧烈的身体活动和青少年过去七天的优质饮食摄入的影响将部分由家庭功能随时间的变化介导。
