Improving Self-Monitoring in Weight Loss With Technology - Full Text View

Purpose

We propose to conduct a randomized study of standard behavioral weight-loss treatment to test if using an electronic diary with or without tailored feedback will improve adherence to self-monitoring and subsequently improve weight loss. Subjects will be randomly assigned to different methods to self-monitor food and exercise habits: (1) use of the traditional paper diary , (2) use of a personal digital assistant (PDA), or (3) use of a personal digital assistant that also provides daily feedback.

Primary Outcome Measures:

Weight Change [ Time Frame: Measured every 6 months ]

Secondary Outcome Measures:

Adherence to self-monitoring [ Time Frame: Measured throughout the study ]
Coronary heart disease risk factors (lipid, glucose, insulin) [ Time Frame: Measures annually ]


Enrollment:	210
Study Start Date:	February 2006
Study Completion Date:	June 2010
Primary Completion Date:	June 2010 (Final data collection date for primary outcome measure)

Intervention Details:

Participants attend group sessions where they learn about healthy eating and exercise. They are asked to self-monitor all calories consumed (food and drink) and all calories expended through exercise. Standard paper diaries are used for self-monitoring.

Detailed Description:

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.
