COMMUNITY STEPS TO MINORITY YOUTH FITNESS

目标：通过改善他们的饮食和增加他们的生活方式体育活动，减少城市中学生肥胖相关疾病的晚期风险的当代标志物。 具体目标。1.从随机选择的城市中学招募125名主要是非洲裔美国人和拉丁裔女孩和男孩（6 - 7年级），并将他们纳入文化定制的，基于社区的生活方式改变计划，旨在通过预防胰岛素抵抗综合征来预防肥胖;将他们的经历与随机选择的对照学校的125名匹配的女孩和男孩进行对比。 2.实施一个全面的，自我效能增强，整个学期的生活方式改变计划，通过减少胰岛素抵抗综合征的风险因素来降低肥胖的风险。 该计划将促进在日常“生活方式”体力活动持续增加的情况下，多吃蔬菜、全水果、全谷物和多吃热量密度降低的食物（例如，有趣的散步、建筑图尔斯之旅、徒步旅行等）。为期一个学期的计划包括每周30分钟的步行和简短的讨论会，在各种社区场所的挑战和更好的饮食选择和增加生活方式的身体活动的好处。 受过训练的同龄人榜样，选定的父母和成人辅导员将提供合理的建议，吃得更好，做更频繁，愉快的体育活动。 在资源有限的情况下，该计划将尝试是多层次的，涉及家长，教师，教练，餐饮服务人员，同行以及研究参与者。 3.在4个月以上的随访（学期末）、12个月和18个月的随访时评估计划的有效性。 主要结果是血清HbA 1c和BMI;次要结果是血清总胆固醇、1英里跑、饮食自我报告、身体活动自我报告。中介变量是自我报告的行为和态度。 4.编写并分发一本资源书，其中包括观察到对这一人群最有效的行为改变策略。

Goal: Reduce contemporary markers of later-in-life risk of obesity-related disease in urban, middle school children by improving their diet and increasing their lifestyle physical activity. Specific Aims. 1. Recruit 125 mostly African American and Latino girls and boys (6th - 7th grades) from a randomly- selected urban middle school and enroll them in a culturally- tailored, community-based lifestyle change program designed to prevent obesity by preventing the insulin resistance syndrome; contrast their experience with 125 matched girls and boys attending a randomly-selected comparison school. 2. Implement a comprehensive, self-efficacy-enhancing, semester-long lifestyle change program to reduce risk of obesity by reducing risk factors comprising the insulin resistance syndrome. The program will promote eating more servings of vegetables, whole fruits, whole grains and more servings of reduced calorie density foods in the context of sustained increases in daily "lifestyle" physical activity (e.g., fun walks, architectural tours, hiking, etc.). The semester-long program includes weekly 30-minute walks and brief discussion sessions in a variety of community venues about the challenges and benefits of better eating choices and increased lifestyle physical activity. Trained peer role models, selected parents and adult facilitators will provide sound advice for eating better and doing more frequent, enjoyable physical activity. Within resource constraints, the program will attempt to be multi-level, involving parents, teachers, coaches, food service staff, peers as well as study participants. 3. Evaluate program effectiveness at 4+ months follow-up (end of the semester), 12 and 18 months follow-up. Primary outcomes are serum HbA1c and BMI; secondary outcomes are serum total cholesterol, 1-mile run, dietary self-report, physical activity self-report. Mediating variables are self-report behaviors and attitudes. 4. Compile and distribute a resource book that includes those behavior change strategies that were observed to work best with this population.
