Impact of a Digital Diabetes Prevention Program on Estimated 8-Year Risk of Diabetes in a Workforce Population.

A digital Diabetes Prevention Program (dDPP) was effective in reducing the risk of diabetes in a workforce population. All modifiable components of a validated diabetes risk score (diastolic BP, systolic BP, BMI, fasting glucose, HDL-cholesterol, triglycerides) improved after the first year of the dDPP compared to the year prior. Objective: We asked whether the estimated 8-year risk of diabetes could be reduced within the first 2 years of a digital Diabetes Prevention Program (dDPP) in a workforce population. Methods: Employees and spouses were eligible if they had prediabetes-range fasting glucose or hemoglobin A1c and body mass index ≥25 kg/m2. Diabetes risk was assessed using the Framingham diabetes risk score in the year before and the 2 years after dDPP initiation. Results: Among participants completing at least nine dDPP lessons (n = 286), diabetes risk decreased 5.3% the year after dDPP initiation, after a 5.4% increase the year before initiation (difference in differences, −10.6%; 95% confidence interval, −13.4% to −7.9%; P < 0.001), with risk maintained at reduced levels after the second year of the program. Conclusion: This dDPP reduced the estimated 8-year risk of diabetes over the first 2 years of the program. [ABSTRACT FROM AUTHOR]
