Background: Over 84 million adults in the U.S. have prediabetes. The CDC National Diabetes Prevention Program (DPP) provides a 12-month structured program to achieve weight loss and increase physical activity to reduce the risk of developing type 2 diabetes.

Methods: A retrospective analysis was performed using data from 658 participants enrolled in the Livongo DPP with a recorded start weight during 2016-2017 and who completed at least 12 lessons, thereby meeting the CDC DPP standards for recognition. Self-monitoring behaviors including weigh-ins, food logging, activity and coach-participant interactions were analyzed at 6 and 12-months. Multiple regression analysis was performed using demographics, self-monitoring and interactions to determine predictors of weight loss at 12-months.

Results: Participants were a mean age of 54 years (SD 10.8), with start weight of 199 pounds (SD 43.7), college educated (82%), and female (72%). On average, participants lost 6.1% of their starting body weight at 6-months and 6.4% at 12-months with 25.2% of participants losing ≥10% at 12 months. Logistic regression analysis showed that each food log was associated with an increase of 0.25% weight loss, a week of 150 active minutes was associated with 0.07% of weight loss, and each lesson completed was associated with 0.21% of increased weight loss.

Conclusions: Overall, participants engaged in the Livongo DPP lost >6% of their start weight with continual weight loss throughout program. More than 25% of highly engaged participants lost ≥10% of their start weight. Food logging was relatively more impactful on weight loss than achieving weeks with 150 minutes of activity completed or lesson attendance.
