Retention is closely linked to clinical outcomes in the National Diabetes Prevention Program (National DPP) lifestyle change program (LCP) . We examined retention, defined as the number of sessions attended, using data collected by the CDC Diabetes Prevention Recognition Program, the quality assurance component of the National DPP. We evaluated participants who enrolled in in-person lifestyle change programs from March 2018 to November 2020 and had the opportunity to complete at least 9 months of the 12-month program. To control for programmatic changes due to COVID-19, we divided enrollment into 3 cohorts: 1) 3/1/2018 - 5/31/2019 (before) , 2) 6/1/2019-2/29/2020 (mixed) , and 3) 3/1/2020-11/30/2020 (during COVID-19 pandemic) . Mean sessions attended was lower in cohort 3 (10.8, p<0.05) than in cohorts 1 (12.9) and 2 (12.6) . As shown in Table 1, across the 3 cohorts the following factors were associated with lower mean number of sessions attended: younger age, Hispanic ethnicity and non-White race, lower educational attainment, and Medicaid as a payer source. Our findings highlight that new strategies could be useful to improve retention among some demographic and socioeconomic groups (e.g., younger adults, Hispanic individuals, individuals with lower educational attainment, and Medicaid recipients) in the National DPP.
