The Centers for Disease Control and Prevention (CDC) estimates that 96 million adults aged 18 years or older had prediabetes in 2019. Of these, 32.2 million, or 33.5%, were aged 18-44, emphasizing the need for efforts to prevent or delay onset of type 2 diabetes within this population. CDC's National Diabetes Prevention Program (National DPP) is a partnership of public and private organizations collaborating to build a nationwide delivery system for a lifestyle change program (LCP) proven to prevent or delay the onset of type 2 diabetes in adults with prediabetes or at high risk. While the mean age of participants in the LCP is 51 years, 31.6% of the participants enrolled as of October 2022 were in the 18-44 age group. When examining the characteristics of this age group, 52.1% of participants identified as non-Hispanic or Latino White, 18.4% identified as Hispanic or Latino, and 12.9% identified as non-Hispanic or Latino Black or African American. Overall, 71.4% of participants in this group enrolled in an online program and 81% participated through a worksite wellness program. For those who had the opportunity to complete the year-long LCP, the mean number of days spent in the program was 110. By comparison, among 45-64-year-olds, the mean number of days spent in the program was 161, and for those 65 and older, the mean number of days was 210. This is of note because participants who stay in the LCP longer are more likely to meet the risk reduction outcomes. Participants 18-44 met the programmatic risk reduction 5% weight loss goal at a lower rate (18.4%) than participants aged 45-64 (27%) and 65 and over (40.2%). These findings highlight the opportunity to develop strategies focused on supporting this younger adult population to enroll in and complete the LCP. Disclosure M.Bell: None. M.Papalii: None.
