497-P: Ten Years of the National Diabetes Prevention Program: The Effect of Interventions on Priority Population Enrollment

Abstract

In 2010, Congress authorized the creation of the National Diabetes Prevention Program to build a nationwide delivery system for a lifestyle change program (LCP) proven to prevent or delay onset of type 2 diabetes. In 2012, the Diabetes Prevention Recognition Program (DPRP) approved its first CDC-recognized organization and in 2012 and 2017, CDC awarded funding to organizations (grantees) to increase enrollment of priority populations. In 2015 and 2018, DPRP Standards expanded approved delivery modes to include online delivery (2015) and distance learning and combined delivery (2018) . As of October 2021, the DPRP has received data from 2,200 organizations on 550,000+ participants ever enrolled in the LCP; this analysis is limited to participants who enrolled prior to 2020. From the end of 2017 to the end of 2019, total enrollment in the LCP more than doubled from 217,115 to 470,7participants. The proportion of participants who identified as Hispanic grew among grantee organizations (6.5% in 2017 to 15.7% in 2019) but remained constant in non-grantee organizations (2.3% in 2017 to 2.2% in 2019) . The proportion identifying as non-Hispanic Black varied across years but overall was higher among grantee organizations (19.9% in 2017, 20.5% in 2018, and 16.2% in 2019) compared to non-grantee organizations (12.0% in 2017, 12.4% in 2018, and 12.8% in 2019) . Between 2017 and 2019, 80-85% of participants identifying as Hispanic enrolled in in-person programs, compared to 11-16.5% in online, 1.1-1.7% in distance learning, and 1.8-2.5% in combination programs. Among participants identifying as non-Hispanic Black, 50.1-58.2% enrolled in online programs each year, compared to 35.8-41.8% in in-person, 3.0-8.3% in combination, and 0.7-2.0% in distance learning programs. These results suggest that enabling organizations to reach priority populations and tailoring delivery modes to each population are effective strategies to increase enrollment.
