The National Diabetes Prevention Program (National DPP) is a partnership of public and private organizations working together to build a nationwide delivery system for a lifestyle change program proven to prevent or delay onset of type 2 diabetes in adults with prediabetes. In 2015, the Diabetes Prevention Recognition Program (DPRP), the quality assurance arm of the National DPP, began recognizing lifestyle change programs delivered through an online platform, meaning participants log into course sessions via a computer, tablet, or smart phone. In November 2018, the total number of participants ever enrolled in the program reached 250,000. Those in online programs have now exceeded the number in in-person programs (144,122 vs. 109,951), despite the fact that online participation is not currently covered as part of the Medicare Diabetes Prevention Program. Among men eligible for participation in the program, more were found to enroll in online programs (65.6%) than in-person programs (34.4%), while among women, the difference was not as great (54.4% online and 45.6% in-person). With respect to age, eligible participants aged 18-44 enrolled in online programs at a rate of 75.5%, while eligible participants 65+ enrolled in in-person programs at a rate of 81.8%, seeming to show that younger participants prefer online, while older participants prefer in-person. Hispanic and white participants enrolled in online at a higher rate than in-person (54.9% and 62.4%), while 51.6% of black participants enrolled in in-person over online. Mean weight loss is used to determine the effectiveness of programs. Participants strive to lose at least 5% of their starting body weight over 12 months. When only eligible participants who were fully engaged for at least 9 of the 12 program months were considered, mean weight loss was found to be 6.3% for in-person programs and 5.4% for online programs. The addition of online programs has allowed the National DPP to reach underserved populations with prediabetes with favorable results.
