DESCRIPTION (provided by applicant): This application is in response to RFA-HL-08-007 "Targeted Approaches to Weight Control for Young Adults". As outlined in the RFA, this application will focus on development, refinement, and evaluation of a behavioral approach to weight control in young adults, with the focus of this application being on enhancing long-term weight loss. Consistent with the RFA, young adults for this application are defined as individuals 18-35 years of age. The prevalence of obesity in young adults has been increasing, and excessive body weight have been linked to numerous chronic conditions including cardiovascular disease, diabetes, many forms of cancer, and numerous musculoskeletal problems. The focus of this application is to develop and evaluate interventions that may be appropriate for young adults to improve weight loss outcomes following a 24 month intervention. Therefore, the primary aim of this study is to examine whether an enhanced weight loss intervention (EWLI) that includes technology components results in improved weight loss in young adults (18-35 years of age) compared to a standard behavioral weight loss intervention (SBWP) over a period of 24 months. Additional aims include examination of these interventions on changes in body composition, body fat distribution, fitness, physical activity, dietary intake, and behavioral/psychosocial measures that may be predictive of behavior change. Assessments will occur at 0, 6, 12,18, and 24 months. This study involves the recruitment of 480 overweight and obese young adults (18-35 years of age). Subjects will participate in a 24 month behavioral weight loss program that includes a reduction in energy ntake and moderate-to-vigorous intensity exercise (progressively increasing from 100 to 300 minutes per week). Subjects will be randomized to receive this intervention (SBWP) or this intervention in combination with technology enhancements (EWLI). EWLI will receive daily text messaging prompts to reinforce adherence to the behavioral intervention from months 7-24, and will wear a monitor from months 13-24 that provides real-time feedback on energy expenditure and achievement of daily physical activity goals. It is hypothesized that these technology enhancements to EWLI will significantly improve weight loss, body composition, body fat distribution, fitness, physical activity, and dietary intake compared to SBWP. RELEVANCE (See instructions): Obesity rates of young adults have significantly increased and the ability to sustain weight loss long-term in this age group has been less than desirable. Therefore, there is a need to develop and implement effective intervention initiatives to address this public health concern, which is the focus of this proposed intervention study.

描述（由申请人提供）：此申请响应RFA-HL-08-007“针对年轻人的重量控制方法”。如RFA中概述的那样，该应用将集中于对年轻人体重控制行为控制方法的开发，改进和评估，其重点是增强长期体重减轻。与RFA一致，该应用的年轻人定义为18-35岁的个人。年轻人肥胖的患病率一直在增加，体重过度与许多慢性病有关，包括心血管疾病，糖尿病，多种形式的癌症以及许多肌肉骨骼问题。该应用的重点是制定和评估可能适合年轻人在24个月干预后改善体重减轻结果的干预措施。因此，这项研究的主要目的是检查包括技术成分的增强体重减轻干预（EWLI）是否会在24个月内与标准行为减肥干预（SBWP）相比，年轻人（18-35岁）（18-35岁）是否会改善年轻人的体重减轻（18-35岁）。其他目的包括检查这些干预措施，这些干预措施对身体成分的变化，体内脂肪分布，健身，体育锻炼，饮食摄入量以及可能预测行为改变的行为/社会心理措施。评估将在0、6、12,18和24个月进行。这项研究涉及招募480名超重和肥胖的年轻人（18-35岁）。受试者将参加24个月的行为减肥计划，其中包括减少能量Ntake和中度到毒的强度运动（逐渐从每周100分钟增加到300分钟）。受试者将被随机接受此干预措施（SBWP）或与技术增强功能（EWLI）结合使用。 EWLI将收到每日文本消息提示，以增强对第7-24个月期的行为干预的遵守，并将佩戴13-24月的监视器，以提供有关能量消耗和实现日常体育活动目标的实时反馈。假设与SBWP相比，这些对EWLI的技术增强将显着改善体重减轻，体内脂肪分布，健身，体育锻炼和饮食摄入量。相关性（请参阅说明）：年轻人的肥胖率显着提高，并且在该年龄段的长期维持体重减轻的能力远远不足。因此，有必要制定和实施有效的干预计划来解决这一公共卫生问题，这是这项拟议的干预研究的重点。 （抽象的结尾）
