ABSTRACT
OBJECTIVE: To evaluate the weight management results of Healthy Incentives, an employer-sponsored wellness program started in 2006 by King County, Washington. METHODS: Changes in body mass index (BMI) and the percentages of those who lost 5% and 10% were compared for first-year participants, 5-year participants, and respondents to the Medical Expenditures Panel Survey (MEPS). RESULTS: A total of 19,559 first-year participants lost weight on average, while the comparative MEPS sample gained weight, -0.80% versus 0.31% (P < 0.01). A total of 10,432 5-year participants also lost weight on average but not as much as during the first year, -0.47% versus -0.80% (P = 0.01). More obese first-year participants lost 5% of BMI than the MEPS sample, 28.5% versus 23.2% (P < 0.01). Thirty eight percent of obese 5-year participants lost 5%. CONCLUSIONS: Healthy Incentives achieved significant weight management benefits for both first-year and 5-year participants.
