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

项目3-摘要/摘要 适度的减肥已被发现对肥胖、血脂和糖尿病风险有好处，但没有 基于社区的干预在糖尿病风险、体重减轻、饮食等方面产生了显著的改善 非裔美国人或拉丁裔男子的练习或身体活动。虽然女性的肥胖率 处于停滞状态的男性，特别是非洲裔和拉丁裔男性的比例正在上升。我们建议 为肥胖的非裔美国人和非裔美国人进行个性化的、基于社区的减肥干预 年龄在40-59岁之间的拉丁裔男性。这是首个经过严格设计、以社区为基础的减肥试验 对这些男性人口统计数据的干预--将干预的效果与关注进行比较 对照组进行为期6个月的随机对照试验。拟议的干预措施包括：(A)有针对性的目标/ 信息(通过网络和文本)，(B)自我监测(通过可穿戴设备和文本)，(C)小组培训和 教育和(D)教育和以社区为基础的信息和资源(通过文本)。这项研究还 包括关于男性气概更深层次的社会和文化方面的第一次健康沟通--性别 这承认了非洲裔美国人和拉美裔男性之间的异质性。这项研究还将探索是否有 基因预测的BMI与基线测量的BMI之间是正相关的。我们假设 被分配到飞行员干预的男性将减掉更多的体重，并展示和保持更大的 改善血糖水平、肥胖、健康饮食、体力活动和心理社会介质 (例如，自我效能感、社会支持、动机)比随机分为注意控制组的那些

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
