Reducing Overweight Among Galveston WIC Participants

摘要本R21研究的目的是确定在社区妇女、婴儿和儿童特殊补充营养计划（WIC）诊所提供的干预措施对3岁儿童超重（年龄和性别的BMI为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提供。该应用程序将测试先前在同一人群中用于减少发育不良发生率（年龄身高< 5%）的干预措施的适应性。该干预措施将适应通过体重稳定而身高增加来降低BMI的目标。此应用程序的具体目标是：1。与常规WIC营养教育相比，检查干预对低收入3岁超重儿童的身高、体重、饮食摄入和缺乏身体活动的影响。对于本应用程序的具体目的，假设如下：1。在干预结束时，实验组儿童与对照组儿童的年龄BMI会有显著差异。2. 与对照组儿童相比，实验儿童对复合碳水化合物的膳食摄入量会显著增加。3. 与对照组儿童相比，实验儿童的简单碳水化合物和脂肪的膳食摄入量会显著减少。4. 与对照组儿童相比，实验儿童缺乏体育活动的水平将显著降低。5. 在干预结束时，实验组儿童与对照组儿童的家庭环境会有显著差异。用于评估干预效果的结果是干预参与者的人体测量、饮食模式、不活动模式和家庭环境的变化。拟议的研究将导致以社区为基础的儿童超重干预，可以通过WIC诊所提供给不同的少数民族儿童。需要创新的策略来预防这些儿童心血管疾病（CVD）和2型糖尿病的发展。该项目的目标是解决超重和肥胖问题，这是我国健康的两个主要健康指标。公共卫生相关性：拟建项目的主要目的是测试一项旨在降低参与WIC项目的低收入、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
