Abstract
Objectives. There is solid evidence that risk for developing type 2 diabetes can be prevented by lifestyle interventions. However, there are few diabetes prevention programs available. Given the increasing prevalence of prediabetes, we sought to investigate if a commercial weight loss program with significant capacity could address this need. This study, conducted in Indianapolis, Indiana in 2014–16, investigated if (Weight Watchers- WW) could cost effectively achieve and sustain sufficient weight loss in persons with prediabetes to reduce diabetes risk for 24 months.
Highlights
Over 84 million adults in the United States have prediabetes.[1]
A previous, randomized controlled trial evaluated the effectiveness of the Weight Watchers® (WW) program in 225 persons with prediabetes as determined by an hemoglobin A1C (HbA1c) value ≥5.7% and ≤6.4% or a self-reported history of gestational diabetes with an HbA1c
5–10% of these individuals will go on to develop diabetes each year.[2]. This has stimulated the development of community-based diabetes prevention programs most of which are implemented by the Young Men’s Christian Association (YMCA) or programs that have been trained by the National Diabetes Prevention Program (NDPP).[3,4]
Summary
Over 84 million adults in the United States have prediabetes.[1]. Without effective intervention strategies, 5–10% of these individuals will go on to develop diabetes each year.[2]. There is a significant need for increased access to low cost, scalable, evidencebased diabetes prevention programs. In 2016, we reported the results of a randomized control trial demonstrating that a nationally available weight loss program, Weight Watchers® (WW), achieved sustained weight loss over a 12-month period among a sample of those with prediabetes, consistent with the weight losses in the Diabetes Prevention Program (DPP) study.[5,6] Here we report weight and glycemic outcomes and cost effectiveness over an 18 and 24 months period to further illuminate the potential for commercial weight loss programs to better meet the need for diabetes prevention programs. We sought to determine if WW could produce sustained weight loss in a cost-effective manner
