项目摘要

DESCRIPTION (provided by applicant): Composite Trials in middle aged adults indicate that weight loss can be achieved and sustained with frequent contact over a long period of time, frequent self-monitoring, social support and motivational counseling. However, it is unclear whether this strategy would work in younger adults. Based on life stage, cultural context, environmental circumstances, and marketing pressures, behavioral Intervention may need to be substantially modified to be effective in young adults. Even more adaptation will be required for intervention to be effective in young adults from racial/ethnic minority groups. The proposed intervention builds on prior evidence with innovations directed at increasing effectiveness in young adults. Using cell phones to deliver a weight control intervention in this age group has the potential to be engaging, enjoyable, practical, cost-effective, sustainable, and broadly disseminated. We propose a trial in which a highly innovative but more risky intervention based almost entirely on use of cell phone technology and a second more incremental innovation over traditional behavioral intervention are each compared to a usual care control group. We will recruit a diverse target population of ovenweight/obese, generally healthy young adults, comprising approximately 35% non-Latino Whites, 35% non-Latino Blacks, and 30% Latinos, to be randomized to: 1) Usual care control: Educational materials and information but no behavioral intervention; 2) Cell-phone intervention: similar education and knowledge as the control group, but thereafter a behavioral intervention will be delivered almost exclusively via cell phone, particularly using the self-monitoring and social networking features of this technology; 3) Personal contact with cell-phone enhancement: personal contact intervention enhanced by cell-phone for self-monitoring. The post-randomization intervention period will last 24 months. The primary outcome is change in weight 12 months post-randomization; an important secondary outcome is weight change at 24 months. The formative phase will focus largely on technology/intervention development. RELEVANCE (See instructions): The obesity epidemic is affecting young adults, leading to increased risk of diabetes, high blood pressure, and cardiovascular disease. Based on life stage, cultural context, environmental circumstances, and marketing pressures, behavioral intervention may need to be substantially modified to be effective in young adults, espcially young minorities. Using cell phones to deliver a weight control intervention has the potential to be engaging, enjoyable, practical, cost-effective, (End of Abstract)

描述（由申请人提供）：针对中年成年人的综合试验表明，通过长期频繁接触、频繁自我监控、社会支持和动机咨询，可以实现并持续减肥。然而，目前尚不清楚这种策略是否适用于年轻人。根据生命阶段、文化背景、环境情况和营销压力，行为干预可能需要进行大幅修改才能对年轻人有效。干预措施要想对少数种族/族裔群体的年轻人有效，还需要更多的适应。拟议的干预措施建立在先前证据的基础上，并进行了旨在提高年轻人有效性的创新。在这个年龄段使用手机提供体重控制干预措施具有吸引力、令人愉快、实用、具有成本效益、可持续和广泛传播的潜力。我们提出了一项试验，其中几乎完全基于手机技术使用的高度创新但风险更大的干预措施以及比传统行为干预措施更多的增量创新均与常规护理对照组进行比较。我们将招募不同的目标人群，即体重/肥胖、总体健康的年轻人，其中包括约 35% 的非拉丁裔白人、35% 的非拉丁裔黑人和 30% 的拉丁裔，并随机分配到： 1) 常规护理控制：教育材料和信息，但无行为干预； 2）手机干预：与对照组类似的教育和知识，但此后几乎完全通过手机进行行为干预，特别是使用该技术的自我监控和社交网络功能； 3）手机增强个人接触：通过手机增强个人接触干预，进行自我监控。随机化后干预期将持续24个月。主要结局是随机分组后 12 个月的体重变化；一个重要的次要结果是 24 个月时的体重变化。形成阶段将主要关注技术/干预措施的开发。相关性（参见说明）：肥胖流行正在影响年轻人，导致患糖尿病、高血压和心血管疾病的风险增加。根据生命阶段、文化背景、环境情况和营销压力，行为干预可能需要进行大幅修改，才能对年轻人，尤其是年轻的少数族裔有效。使用手机进行体重控制干预可能具有吸引力、令人愉快、实用且具有成本效益，（摘要结束）
