Project-3 Tailored behavioral intervention for overweight African Americans and Latino men

项目3-摘要/摘要 适度的减肥已经被发现对肥胖、血脂和糖尿病风险有有益的影响， 以社区为基础的干预措施在糖尿病风险、体重减轻、饮食 非裔美国人或拉丁美洲人的实践或体育活动。虽然女性的肥胖率 男性，特别是非洲裔美国人和拉丁美洲人的死亡率趋于稳定，但正在上升。我们建议 为肥胖的非洲裔美国人进行个性化的，以社区为基础的减肥干预， 40-59岁的拉丁裔男性。这项试点研究是第一个严格设计的，以社区为基础的减肥 针对这些男性人口统计数据的干预-将比较干预的有效性， 对照组为6个月随机对照试验。拟议的干预措施包括（a）有针对性的目标/ 消息（通过网络和文本），（B）自我监测（通过可穿戴设备和文本），（c）小组培训， 教育和（d）教育和社区信息和资源（通过文本）。该研究还 包括第一次针对性别的健康宣传，涉及男子气概的更深层次的社会和文化方面 承认非洲裔美国人和拉丁裔男性的异质性。该研究还将探讨是否有 基因预测的BMI和基线测量的BMI之间呈正相关。我们假设 被分配到试点干预的男性将减轻更多的体重， 改善血糖水平、肥胖、健康饮食、体力活动和心理社会介质 (e.g.,自我效能感、社会支持、动机）显著高于随机分配到注意控制组的学生

Project 3- Abstract/Summary Modest weight-loss has been found to have beneficial effects on obesity, lipid profiles and diabetes risk, yet no community-based intervention has produced significant improvements in diabetes risk, weight loss, eating practices or physical activity in African American or Latino men. While the rates of obesity among women have plateaued, the rates for men, particularly African American and Latino men are increasing. We propose to conduct an individually-tailored, community-based weight-loss intervention for obese African American and Latino men ages 40-59. This pilot study - which is the first rigorously designed, community-based weight-loss intervention for these demographics of men - will compare the efficacy of the intervention to an attention control group in a 6-month randomized-controlled trial. The proposed intervention includes (a) tailored goals/ messages (via web and text), (b) self-monitoring (via wearable device and text), (c) small group training and education and (d) educational and community-based information and resources (via text). The study also includes the first health communications gender-tailored on deeper social and cultural aspects of masculinity that recognizes the heterogeneity among African American and Latino men. The study also will explore if there is a positive correlation between genetically predicted BMI and BMI measured at baseline. We hypothesize that men assigned to the pilot intervention will lose more weight and demonstrate and maintain greater improvements in blood glucose levels, adiposity, healthy eating, physical activity, and psychosocial mediators (e.g., self-efficacy, social support, motivation) than those randomized to the attention control group
