Reducing Overweight Among Galveston WIC Participants

描述(申请人提供)：这项R21研究的目的是确定在社区妇女、婴儿和儿童补充营养计划(WIC)诊所提供的干预措施对3岁儿童儿童超重(年龄和性别的BMI和GT；95%)的影响。干预措施将通过加尔维斯顿县WIC诊所的营养教育课程进行。该应用程序将测试先前在同一人群中用于降低发育迟缓发生率(年龄身高为5%)的干预措施的适应性。干预措施将调整为在身高增加的同时，通过稳定体重来降低BMI。本应用程序的具体目的是：1.与常规的WIC营养教育相比，检查干预对超重的低收入3岁儿童的身高、体重、饮食摄入量和缺乏运动的影响。本研究的具体目的假设如下：1.干预结束时，实验组儿童的年龄BMI与对照组儿童相比有显著差异。2.与对照儿童相比，实验儿童膳食中复合碳水化合物的摄入量将显著增加。3.与对照儿童相比，实验儿童对简单碳水化合物和脂肪的饮食摄入量将显著减少。4.与对照儿童相比，实验儿童的身体活动不足程度将显著降低。5.干预结束时，实验组儿童的家庭环境与对照组儿童相比有显著差异。用于评估干预效果的结果是干预参与者的人体测量学、饮食模式、不活动模式和家庭环境的变化。这项拟议的研究将产生一种基于社区的儿童超重干预措施，可以通过WIC诊所提供给不同的少数族裔儿童。需要创新策略来预防这些儿童的心血管疾病(CVD)和2型糖尿病的发展。这个项目的目标是解决超重和肥胖，这是我国健康的两个主要健康指标。公共卫生相关性：拟议项目的主要目的是测试一项旨在降低参加WIC计划的低收入、超重儿童的BMI的计划

DESCRIPTION (provided by applicant): Abstract The purpose of this R21 study is to determine the impact of an intervention delivered in neighborhood Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinics on childhood overweight (BMI> 95 percent for age and sex) in 3 year old children. The intervention will be delivered through nutrition education classes at the WIC clinics in Galveston County. This application will test the adaptation of an intervention that has been previously used in the same population to reduce incidence of stunted growth (height for age < 5 percent). The intervention will be adapted to target BMI reduction through weight stability while height increases. The specific aim of this application is: 1. Examine the effects of the intervention, compared to routine WIC nutrition education, on height, weight, dietary intake, and physical inactivity of low-income 3 year old children who are overweight. The hypotheses for the specific aim of this application are as follows: 1. There will be a significant difference in the BMI for age between the children in the experimental group compared to the children in the control group at the end of the intervention. 2. There will be a significant increase in the experimental children's dietary intake of complex carbohydrates when compared to control children. 3. There will be a significant decrease in the experimental children's dietary intake of simple carbohydrates and fat when compared to control children. 4. There will be a significant decrease in the experimental children's levels of physical inactivity when compared to control children. 5. There will be a significant difference in the home environment between the children in the experimental group compared to the children in the control group at the end of the intervention. The outcomes used to evaluate intervention effectiveness are changes in anthropometrics, dietary patterns, inactivity patterns, and home environments of intervention participants. The proposed study will result in a community-based intervention for childhood overweight that can be delivered to diverse minority children through WIC clinics. Innovative strategies are needed to prevent the development of cardiovascular disease (CVD) and type 2 diabetes in these children. The goals of this project address overweight and obesity, two leading health indicators for our nation's health. PUBLIC HEALTH RELEVANCE: The primary purpose of the proposed project is to test a program designed to reduce BMI in low-income, overweight children who participate in the WIC program
