Family Based Obesity Prevention in Latino Families

描述（由申请人提供）：肥胖在美国很流行，并且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。2至5岁的非西班牙裔白人和非裔美国儿童的超重率相当。然而，超重的患病率在学龄前墨西哥裔美国儿童中要高得多。因此，如果我们要有效地解决这一公共卫生危机，学龄前是改变高危儿童超重轨迹的关键时期。拟议的研究是一项探索性/发展性应用，并响应PA-06-351“癌症控制行为研究的探索性资助”和PA-06-417“以学校为基础的预防肥胖干预”。该项目基于“Hip Hop to Health Jr.”（HL58871）的研究结果。Hip Hop的主要目的是比较两组3-5岁少数民族儿童随机分为体重控制干预组（WCI）和一般健康干预组（GHI）的体重指数（BMI） [kg/m2]的变化。1年和2年随访的结果显示，与GHI对照组相比，WCI组儿童的BMI相对增幅明显较小。在以黑人儿童为主的学校中，取得了成功。在第一年和第二年对拉丁裔儿童的随访结果没有显示出同样的阳性结果。拉丁裔学校的潜在限制是干预完全以学校为基础，很少有家长干预，对识字水平和文化能力的关注不够。我们现在提出了一项干预措施，以测试拉丁裔家庭超重预防干预措施的可行性/可接受性，“Ni¿os Felices, Ni¿os Sanos”（快乐健康的孩子），该干预措施利用学校环境，提供与儿童的持续接触，更容易接触父母，以及对教育环境的信任。我们提出了三个目标：目标1：测试3-5岁拉丁裔儿童及其父母对14周家庭干预的可接受性；目标2。评估该干预措施的有效性，该干预措施旨在显示3-5岁拉丁裔儿童在干预后和第1年随访时适合生长的BMI平均较小变化；和Aim 3。在干预后和第一年的随访中，评估3-5岁拉丁裔儿童及其父母在电视观看、体育活动、脂肪、纤维和水果和蔬菜摄入量方面的干预效果。肥胖症在美国很流行。许多与肥胖相关的危险因素在少数民族人群中非常明显，在拉丁裔儿童中也是一个严重的问题。如果我们要有效地影响公众健康，学龄前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.
