Prevention of diabetes demonstrated in the diabetes prevention program has not been thoroughly evaluated in workplace settings.
Glycemic control was assessed by glycated hemoglobin (HbA1c) and its impact on 5-year incidence of diabetes and prediabetes prevalence, in wellness program participants (WPP) of (Group A, with) or (Group B, without) health coaching and monetary incentives.
HbA1c fell in Group A WPP (5.52 ± 0.60 vs 5.58 ± 0.36 SD, P = 0.04) as did prediabetes. Incident diabetes was less than expected (24 vs 74, P < 0.001). HbA1c increased in Group B WPP (5.37 ± 0.40 SD vs 5.58 ± 0.54, P < 0.001) and prediabetes increased from 28 to 36 (P < 0.001).
Health coaching and monetary incentives improved glycemic control over 5 years, an improvement not observed in WPP without these interventions.

Clinical Significance: Health coaching and monetary incentives improved glycemic control over 5 years in wellness program participants (WPP). Prediabetes decreased by 40% and incident diabetes was only 32% of that expected. No such improvements were observed in WPP not provided with such interventions. However, blood lipoproteins improved in both groups.
No potential conflicts of interest were reported.
