Improving Self-Monitoring in Weight Loss with Technology

描述（由申请人提供）：肥胖是一种主要的慢性健康问题，是冠心病（CHD）的独立危险因素，其患病率继续以惊人的速度增加。虽然体重控制研究显著提高了短期治疗的成功率，但长期减肥维持却落后了。研究表明，自我监控饮食和体育活动习惯与成功之间存在一致的关系。 体重减轻以及维持体重减轻。然而，主要用于自我监测的方法仍然是纸质日记（PD），这是耗时和繁重的。此外，PD不允许即时的外部反馈来支持和激励个人。新兴技术可以改善自我监测和减肥治疗。然而，使用这些技术进步，如个人数字助理（PDA），还没有研究在减肥治疗。这项行为减肥治疗研究的主要目的是确定在促进和维持短期和长期减肥方面，使用PDA进行日常饮食和身体活动习惯的自我监测（有或没有定制的反馈干预）是否上级使用PD。次要目的包括比较治疗组分配对自我监测依从性和CHD风险因素（血脂、血糖、胰岛素、C反应蛋白）的影响。我们提出 招募198名受试者，并将他们随机分配到三个治疗组中的一个，这三个治疗组将使用不同的方法来自我监测饮食和身体活动习惯：（1）使用传统PD，并延迟书面反馈，（2）使用PDA，并对每日目标进行有限反馈，或（3）使用PDA，并对每日目标进行有限反馈，并通过PDA接收每日受试者定制的反馈消息。拟议的研究包括长期（24个月）的自我管理的监督与三个重要组成部分：自我监测，反馈和持续的联系。受试者将在基线、6、12、18和24个月时完成评估。这项创新的研究将提供信息的有效性相结合的技术进步与成熟的行为策略。

DESCRIPTION (provided by applicant): The prevalence of obesity, a major chronic health problem that is an independent risk factor for coronary heart disease (CHD), continues to increase at an alarming rate. Although weight control research has significantly improved short-term treatment success, long-term weight loss maintenance has lagged behind. Research has demonstrated a consistent relationship between self-monitoring eating and physical activity habits and success in weight loss as well as in maintenance of weight loss. However, the methods primarily used for self-monitoring continue to be the paper diary (PD), which is time consuming and burdensome. Moreover, PDs do not permit immediate external feedback to support and motivate the individual. Emerging technologies could improve self monitoring and weight loss treatment. However, the use of these technological advances, such as a personal digital assistant (PDA), has not been studied in weight loss treatment. The primary aim of this behavioral weight loss treatment study is to determine if self-monitoring of daily eating and physical activity habits using a PDA, with or without a tailored feedback intervention, is superior to using a PD in terms of promoting and maintaining short and long-term weight loss. Secondary aims include comparing the effect of treatment group assignment on adherence to self-monitoring and on risk factors for CHD (lipids, glucose, insulin, C-reactive protein). We propose to enroll 198 subjects and randomize them to one of three treatment groups that will use different methods to self monitor eating and physical activity habits: (1) use of the traditional PD with delayed written feedback, (2) use of a PDA with limited feedback on daily targets, or (3) use of a PDA with limited feedback on daily targets plus receive daily, subject-tailored feedback messages via the PDA. The proposed study includes prolonged (24 months) supervision of self-management with three important components: self-monitoring, feedback, and ongoing contact. Subjects will complete assessments at baseline, 6, 12, 18, and 24 months. This innovative study will provide information on the efficacy of combining technological advances with proven behavioral strategies.
