Financial Incentive Strategies for Weight Loss in Obese Patients Living in Socioeconomically Disadvantaged Neighborhoods
In Brief
A clinical study evaluating Goal-Directed Financial Incentives, Enhanced Usual Care, and 1 other intervention for Obese. Completed, enrolled 668 participants across 2 sites.
Detailed Summary
Financial incentives for motivating changes in health behavior, particularly for weight loss in obese individuals, are increasingly being tested by health insurers, employers, and government agencies. However, a key unanswered question regarding weight loss is how to structure these incentive programs to maximize their effectiveness, acceptability to patients, and economic sustainability. Focusing on obese patients living in neighborhoods with a high concentration of low socioeconomic status households, the investigators will compare the impact of financial incentives for weight loss on sustained weight loss, use of evidenced-based therapy, and quality of life, and they will determine their short-term and long-term return on investment.
Study Details
Timeline
Interventions
Patients will receive financial incentives for using a food diary, verified by entries in in the BookFactory Food Diary or another food diary, including internet/app-based diaries ($30 monthly); achieving 75 minutes of physical activity per week in first three months, as verified by a wearable fitness tracker ($20 monthly); achieving 150 minutes of physical activity per week in last three months, as verified by a wearable fitness tracker ($20 monthly); enrollment in a clinic-based or commercial weight loss program ($150 one time); and active participation in clinic-based or commercial weight loss program, as verified by the program ($60 monthly).
Patients will receive a food diary (BookFactory Food Diary), wearable fitness tracker (Fitbit), exercise and nutrition education materials (American Heart Association's Walking For Better Health and How to Eat Healthy), and referral information for intensive weight loss programs. This information will comprise these commercial and hospital-based weight loss programs that are evidence-based: Weight Watchers and Jenny Craig; the Veterans Administration's MOVE! and TeleMOVE! programs; Bellevue Hospital's Medical Weight Management Clinic and Intensive Nutritional Treatment programs; and New York University Langone Medical Center's Weight Management Program. We will also provide brief instructions on how to use the food diary and Fitbit Charge HR.
Patients will receive financial incentives for clinically significant weight loss, as confirmed at monthly weigh-ins. At 30 days, they will receive $50 if they lose ≥1.5% to \<2.5% of baseline weight or $100 if they lose ≥2.5% of baseline weight. At 2 months and 3 months, they will receive $50 if they lose ≥2.5% to \<5% of baseline weight or $100 if they lose ≥5% of baseline weight. At 4, 5, and 6 months, they will receive $100 if they lose ≥2.5% to \<5% of baseline weight or $150 if they lose ≥5% of baseline weight. To employ the behavioral economic concept of regret aversion, patients will be given feedback at each assessment point about incentives they would have received had they achieved a loss of at least 2.5% of baseline weight.
