RESEARCH BRIEF — Volume 21 — March 27, 2024
PEER REVIEWED
Of the 599 participants enrolled, 299 were randomized to the intervention group (digital DPP) and 300 to the comparison group (small-group education). Of the 299 intervention group participants, 262 completed the 4-month assessment and had a mean (SD) weight loss of 11.3 (0.8) pounds; 243 completed the 12-month assessment and lost a mean (SD) 12.2 (0.9) pounds. Of the 300 comparison group participants, 176 enrolled in a post-trial DPP. Of those, 103 had weigh-in data 4 months post-trial showing a mean (SD) weight loss of 7.2 (10.1) pounds; of those, 69 had weigh-in data at 12 months showing a mean (SD) weight loss of 6.8 (13.7) pounds.
