Project Summary Child obesity disproportionately impacts young Latino children. Obesity interventions focusing on 2- to 5- year-olds are critical as excessive weight gain during this period increases the risk of adolescent and adult overweight and has important implications for later health problems. Moreover, many obesogenic behaviors in adulthood, like television viewing and consumption of sugary drinks, begin at this age. The most effective childhood obesity interventions are those rooted in behavior and family systems theories. Both of these theories provide approaches to support lifestyle changes with an understanding that family is the major mediator of social influences on a child’s development. To date, however, most family-based interventions: (1) focus on one parent, typically mothers; (2) miss the opportunity to leverage the Latino cultural value of familism (i.e. family connectedness) to impact childhood obesity outcomes; and (3) include lengthy curricula requiring weekly in-person sessions over a 2- to 6-month time period. The rationale for the proposed study is to address these shortcomings by evaluating the effectiveness of a community-based intervention that is shorter and involves multiple family caregivers. The intervention will include in-person and mobile phone components focusing on Latino caregivers of young children, to support evidence-based and age appropriate dietary, media-viewing, and physical activity practices among 2- to 5-year old children, in order to decrease ethnic disparities in childhood obesity. The study will also explore the intervention’s potential to multiply the public health benefit by reducing obesity risk for adult caregivers. A prospective randomized study design will be used to evaluate the effectiveness of the family-based childhood obesity intervention on child BMI at 6- months (primary outcome) and at 12 months (secondary outcome), compared to a usual WIC care group. The study will randomize approximately 260 adult Latino caregivers of 2- to 5-year old children (2 caregivers per child) and half will be assigned to the intervention, and the other half will serve as the control group. All families will be recruited from four WIC Centers in Los Angeles County. Primary and secondary outcomes will include: (1) changes in child BMI outcomes at 6- and 12 months; (2) changes in child dietary, media-viewing, and physical activity practices; (3) whether familism attenuates or amplifies the intervention’s effect on differences in child BMI change between intervention and WIC usual care group; and (4) changes in caregiver’s dietary, physical activity, and weight. Pre- and post-intervention anthropometric and survey data will be collected at baseline, 1-, 6-, and 12-months post-baseline to estimate the intervention effect size on child BMI and weight-related practices, and explore whether familial mechanisms moderate the intervention’s effect on child BMI.

项目摘要 儿童肥胖症不成比例地影响年轻的拉丁裔儿童。肥胖干预措施的重点是2至5- 年龄至关重要，因为在此期间体重增加会增加青少年和成人的风险 超重，对以后的健康问题具有重要意义。此外，许多肥胖行为 成年，就像电视观看和消费含糖饮料一样，从这个时代开始。最有效的 儿童肥胖干预措施是植根于行为和家庭系统理论的肥胖。这两个 理论提供了支持生活方式改变的方法，并了解家庭是主要的 社会影响对儿童成长的调解人。但是，迄今为止，大多数基于家庭的干预措施：（1） 专注于一位父母，通常是母亲； （2）错过了利用拉丁裔熟悉的文化价值的机会 （即家庭联系）影响儿童肥胖结果； （3）包括冗长的课程 在2到6个月的时间内每周一次的面对面会议。拟议研究的理由是解决 通过评估较短的社区干预措施的有效性，这些缺点 涉及多个家庭护理人员。干预将包括面对面和手机组件 专注于幼儿的拉丁裔护理人员，以支持循证和适合年龄的饮食， 2至5岁儿童的媒体观看和体育锻炼实践，以减少种族 儿童肥胖的差异。该研究还将探索干预措施增加公众的潜力 通过减少成人护理人员的肥胖风险来益处。将使用前瞻性随机研究设计 评估基于家庭的儿童肥胖对儿童BMI的有效性6个月 （主要结果）和12个月（第二结果），与通常的WIC护理组相比。研究 将对2至5岁儿童的大约260个成人拉丁裔护理人员（每个孩子2名看护人） 一半将分配给干预措施，另一半将作为对照组。所有家庭都会 可以从洛杉矶县的四个WIC中心招募。主要和次要结果将包括：（1） 6个月和12个月的儿童BMI结果的变化； （2）儿童饮食，媒体观看和身体的变化 活动实践； （3）熟悉性是减弱还是放大器，干预对儿童差异的影响 BMI在干预和WIC常规护理小组之间发生变化； （4）看护人的饮食，身体的变化 活动和体重。干预前后的人体测量学和调查数据将在基线1-，1-， 6个月和12个月后，以估计对儿童BMI的干预效果和与体重有关的效果 实践，探索家庭机制是否会使干预对儿童BMI的影响是否适应。
