Pilot Study of the HWL Program

Not Applicable

Completed

• Conditions: Overweight and Obesity
• Interventions: Behavioral: Home weight loss program

• Registration Number: NCT03439579
• Lead Sponsor: Medical University of South Carolina

Brief Summary

The goal of the project is to test a remotely delivered, standalone behavioral weight loss intervention designed to help adults initiate the important dietary, physical activity (PA) and behavioral changes necessary to achieve weight loss.

Detailed Description

The Weight Management Center currently offers a remotely delivered (smart phone, tablet, computer) program to assist patients with maintaining weight losses already achieved, which includes multi-channel self-monitoring and asynchronous individually recorded feedback from clinical staff. The goal of the presently proposed project is to build on this existing maintenance-focused program to create a remotely delivered, standalone behavioral weight loss intervention designed to help participants initiate the important dietary, physical activity (PA) and behavioral changes necessary to achieve weight loss. We recently developed the Home Weight Loss (HWL) program by repackaging existing clinical educational materials as instructional lifestyle change modules to be delivered remotely for participant weight loss

The aim of the proposed project are to pilot test the effects of the HWL program among a sample of overweight and obese adults (N=30). The digital platform currently used in the maintenance program will be used for the HWL program

Arm && Interventions

Group	Intervention	Description
Home weight loss program	Home weight loss program	Participants will be instructed to daily monitor their body weight, minutes of activity, number of steps, and calories consumed for the duration of the pilot study, and they will receive recorded individualized feedback on this self-monitored data from Weight Management Center clinicians (registered dietitians, exercise psychologists, and behavioral specialists).

Primary Outcome Measures

Name	Time	Method
Body weight change	12 weeks	body weight change (kg) from pre-to post

Secondary Outcome Measures

Name	Time	Method
program satisfaction	12 weeks	program satisfaction obtained from multiple choice items developed by study staff. Subjects are asked to rate their level of agreement with items assessing their satisfaction with the overall program, available responses range from extremely satisfied to not at all satisfied.
changes in body mass index	12 weeks	weight in kgs divided by height in meters squared to obtain BMI (kg/m\^2)
usability of program components	12 weeks	examine usage of tracking components including step, exercise, diet, and weight tracking
changes in scores on the power of food scale	12 weeks	use of the Power of Food Scale (PFS). This is a validated 15-item scale with responses scored and ranging between 1 (do not agree) and 5 (strongly agree) with the statements. Higher scores indicate less favorable outcomes, as higher scores indicate increased patient susceptibility to food in the environment.
changes in body fat percentage	12 weeks	changes in body fat percentage
changes in eating behavior scores	12 weeks	use of the Eating Behavior Inventory (EBI). This is a validated 26-item scale assessing eating and weight control behaviors. Subjects indicate agreement with statements with reponse options ranging in values from 1 (never or hardly ever) to 5 (always or almost). Higher values are indicative of those most associated with weight loss (e.g., self-monitoring caloric intake) and are therefore associated with better weight loss outcomes following behavioral weight management intervention.
changes in body weight as a percentage of start weight	12 weeks	percent body weight change
changes in waist and hip measurements	12 weeks	changes in waist and hip measurements
