Cell phone Intervention Trail for Young Adults (CITY)

描述(申请人提供)：中年综合试验表明，通过长时间的频繁接触、频繁的自我监测、社会支持和励志咨询，减肥是可以实现和持续的。然而，目前还不清楚这一策略是否适用于年轻人。基于生活阶段、文化背景、环境环境和营销压力，行为干预可能需要进行实质性的修改，才能在年轻人中有效。要使干预措施对来自种族/少数民族群体的年轻人有效，还需要更多的适应。拟议的干预建立在先前证据的基础上，采用旨在提高年轻人有效性的创新。在这个年龄段，使用手机进行体重控制干预具有吸引力、趣味性、实用性、成本效益、可持续和广泛传播的潜力。我们提出了一项试验，其中一项高度创新但风险更高的干预几乎完全基于手机技术的使用，另一项比传统行为干预更具增量的干预分别与普通护理控制组进行比较。我们将招募体重/肥胖、一般健康的年轻成年人的多样化目标人群，其中约35%为非拉丁裔白人，35%为非拉丁裔黑人，30%为拉丁裔，随机分为：1)日常护理对照组：教育材料和信息，但没有行为干预；2)手机干预：与对照组相似的教育和知识，但此后行为干预将几乎完全通过手机提供，特别是使用这项技术的自我监控和社交网络功能；3)个人接触手机增强：通过手机加强个人接触干预，进行自我监控。随机后干预期将持续24个月。主要结果是随机化12个月后体重的变化；一个重要的次要结果是24个月时体重的变化。形成阶段将主要侧重于技术/干预开发。 相关性(见说明)：肥胖症流行正在影响年轻人，导致糖尿病、高血压和心血管疾病的风险增加。基于生活阶段、文化背景、环境环境和营销压力，行为干预可能需要进行实质性的修改，才能在年轻人，特别是年轻的少数族裔中有效。使用手机进行体重控制干预具有吸引力、趣味性、实用性和性价比的潜力。

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)
