The purpose of this study is to determine the effectiveness of a Nutrition Activation program to change dietary habits of low-income, obese African American women who are at risk for Non-Insulin-Dependent Diabetes Mellitus (NIDDM). The Activation program consists of a combination of strategies based upon Social Learning Theory, such as peer role modeling, staging, and group social support. A second focus of the study is to evaluate the impact of the program on reducing risk factors for NIDDM and obesity through a measurement of Body Mass Index, blood pressures, lipid levels, and waist-hip ratios. The proposed study will include 250 obese low-income African American women who will be recruited through collaborative efforts with Grace Hill Neighborhood Services, a social service organization located in the target community. The subjects will be randomized into either the Activation condition or a no-treatment control group condition. The Activation program will be delivered over a one-year period by trained peers from the target community. Intervention activities will consist of experiential learning exercises implemented within the target neighborhoods that focus on knowledge and skills related to: healthy food shopping, label reading, developing shopping tip sheets, creating low fat, high fiber recipes. Social support groups led by Nutrition Neighbors will be available to subjects in the Activation condition. Evaluation of the program will be performed through comparison of data assessed during pre-, post-, and six- month follow-up interviews. Assessments will include: l) knowledge and attitudes relating to nutrition and diet; 2) lifestyle risk factors such as smoking, physical activity; 3) dietary habits; 4) 24-Hour Dietary Recall (to be performed quarterly or 6 times for each subject); 5) food frequencies; 6) perceived social support; 7) physical data that includes Body Mass Index, blood pressure, waist-hip ratios, and lipid levels. Data analysis will include descriptive and multivariate analytic techniques to determine the impact of the program on outcome variables. Knowledge derived from this study will help identify effective strategies to reduce obesity and other risk factors of NIDDM among an underserved high risk population.

本研究的目的是确定营养的有效性 激活计划，以改变低收入，肥胖的非洲人的饮食习惯 有患非胰岛素依赖型糖尿病风险的美国女性 （NIDDM）。激活计划包括一系列策略 基于社会学习理论，如同伴角色建模，分期， 和团体社会支持。研究的第二个重点是评估 该计划对减少NIDDM和肥胖风险因素的影响 通过测量身体质量指数，血压，血脂水平， 和腰臀比。 这项拟议中的研究将包括250名肥胖的低收入非洲裔美国人 这些女性将通过与格雷斯·希尔的合作招募， 邻里服务，一个社会服务组织，位于目标 社区受试者将被随机分配至激活组 条件或无处理对照组条件。激活 该计划将在一年的时间内由来自 目标社区。干预活动将包括经验性的 在目标社区内实施的学习练习， 与健康食品购物、标签阅读、 开发购物小贴士，创建低脂肪，高纤维食谱。 由营养邻居领导的社会支持团体将提供给 处于激活状态的对象。对该方案的评估将是 通过比较评估前、后和六年期间的数据进行， 一个月的后续采访。评估将包括：l）知识和 与营养和饮食有关的态度; 2）生活方式风险因素， 吸烟、体力活动; 3）饮食习惯; 4）24小时饮食 召回（每季度或每例受试者6次）; 5）食物 频率; 6）感知的社会支持; 7）物理数据，包括 体重指数、血压、腰臀比和血脂水平。 数据 分析将包括描述性和多变量分析技术， 确定项目对结果变量的影响。知识 这项研究将有助于确定有效的战略，以减少 肥胖和NIDDM的其他危险因素 人口
