Are Digital Diabetes Prevention Programs (d-DPPs) Effective in Improving Outcomes in Prediabetics?

A RCT with 599 prediabetic patients was conducted to determine the effectiveness of a digital diabetes prevention program in improving weight and HbA1c.

The participants were randomized to:

  • d-DPP group
  • Single-session small-group diabetes-prevention class



Engagement in d-DPPs Was Significantly Related to Improved HbA1c and Weight Loss. d-DPPs can be an Effective Clinical Strategy for Diabetes Support.


d-DPPs: Digital Diabetes Prevention Programs, HbA1c: Glycated hemoglobin.
