Family Based Obesity Prevention in Latino Families

描述(由申请者提供)：肥胖在美国很流行，并与许多医疗问题的风险增加有关。许多与肥胖相关的危险因素和疾病在少数民族人群中非常明显。在两到五岁的非西班牙裔白人和非洲裔美国儿童中，超重率也有类似的情况。然而，在学龄前墨西哥裔美国儿童中，超重的患病率要高得多。因此，如果我们要有效地解决这一公共卫生危机，学龄前几年是改变高危儿童超重趋势的关键时期。这项拟议的研究是一项探索性/开发性应用，是对PA-06-351“癌症控制行为研究的探索性资助”和PA-06-417“预防肥胖的学校干预措施”的回应。该项目建立在“Hip Hop to Health Jr.”发现的基础上。(HL58871)。Hip Hop的主要目的是比较体重控制干预(WCI)和一般健康干预(GHI)两组3-5岁少数民族儿童体重指数(BMI)[kg/m2]的变化。第一年和第二年的随访结果显示，与GHI对照组的儿童相比，WCI组的儿童BMI的相对增幅明显较小。成功的学校主要是为黑人儿童提供服务的学校。拉丁裔儿童在第一年和第二年的随访结果没有显示出同样的积极结果。拉丁裔学校的潜在限制是，干预完全是以学校为基础的，家长的干预最少，而且对识字水平和文化能力的关注不够。我们现在提议一项干预措施，以测试针对拉丁裔家庭的超重预防干预措施的可行性/可接受性，该干预措施利用了学校环境的优势，提供了与儿童持续接触的机会，更容易接触到父母，并在教育环境中获得了信任。我们提出了三个目标：目标1：测试对3-5岁拉美裔儿童及其父母进行为期14周的家庭干预的可接受性；目标2.评估这项干预的有效性，该干预旨在显示干预后和1岁时3-5岁拉美裔儿童的BMI平均变化较小；以及目标3.评估这项旨在改变3-5岁拉美裔儿童及其父母在干预后和1岁随访时观看电视、体力活动、脂肪、纤维和水果蔬菜摄入量的有效性。肥胖症在美国很流行。许多与肥胖相关的危险因素在少数族裔人群中非常明显，在拉丁裔儿童中也是一个重大问题。如果我们要有效地影响公共卫生，学龄前几年是进行干预的关键时期。

DESCRIPTION (provided by applicant): Obesity is epidemic in the United States and is associated with increased risk for numerous medical problems. Many obesity-related risk factors and diseases are strikingly apparent in minority populations. Comparable rates of overweight exist for two to five year old non-Hispanic white and African-American children. However, the prevalence of overweight is considerably higher among preschool Mexican American children. Thus, the preschool years are a crucial time to alter the trajectory toward overweight among high-risk children if we are to effectively address this public health crisis. The proposed research is an exploratory/developmental application and responds to PA-06-351 "Exploratory Grants for Behavioral Research in Cancer Control" and to PA-06-417 "School-Based Interventions to Prevent Obesity." The project builds upon findings of "Hip Hop to Health Jr." (HL58871). The primary aim of Hip Hop was to compare changes in body mass index (BMI) [kg/m2 ) in two groups of 3-5 year old minority children randomized to a Weight Control Intervention (WCI) or a General Health Intervention (GHI). Results for the children at the Year 1 and Year 2 follow-ups showed that children in WCI had significantly smaller relative increases in BMI compared to children in the GHI control group. The success was among the schools that served predominantly Black children. Results at Year 1 and Year 2 follow-up for the Latino children did not show these same positive results. Potential limitations for the Latino schools were that the intervention was solely school-based with a minimal parental intervention and not sufficient in its attention to literacy level and cultural competence. We now propose an intervention to test the feasibility/acceptability of an overweight prevention intervention for Latino families, "Ni¿os Felices, Ni¿os Sanos" (Happy Healthy Kids) that takes advantage of the school setting which provides continuous contact with children, easier access to parents, and trust in the educational setting. We propose three aims: Aim 1: To test the acceptability of a 14-week family-based intervention with 3-5 year old Latino children and their parents; Aim 2. To estimate the effectiveness of this intervention designed to show smaller changes, on average, in BMI appropriate for growth in 3-5 year old Latino children at post-intervention and Year 1 follow-up; and Aim 3. To estimate the effectiveness of this intervention designed to produce changes in television viewing, physical activity, fat, fiber, and fruit and vegetable intake in 3-5 year old Latino children and their parents at post-intervention and Year 1 follow-up. Obesity is epidemic in the United States. Many obesity-related risk factors are strikingly apparent in minority populations and are a significant problem among Latino children. The preschool years are a crucial time to intervene if we are to effectively impact public health.
