Introduction & Objective: Since 2012, the Centers for Disease Control and Prevention (CDC) has recognized organizations, through the Diabetes Prevention Recognition Program, that deliver the National Diabetes Prevention Program lifestyle change program (LCP) and achieve specific metrics. Organizations enroll adults at high risk for type 2 diabetes and submit data to CDC for evaluation.
Methods: Because data have shown that retention is key to achieving outcomes that reduce risk of type 2 diabetes, we used a Cox model to compute hazard ratios (HR) of early dropout and survival curves for being retained in the program using data from 403,392 adults who enrolled 1/1/2012-8/31/2022. The model included sex, race/ethnicity, and age, and time in the program was censored at day 274. The racial/ethnic groups American Indian/Alaska Native, Asian/Asian American, Native Hawaiian/other Pacific Islander, and Multiracial were combined due to small numbers (5.3% of total). Analysis was limited to in-person and online programs.
Results: We saw no difference in dropout rates for men vs. women in in-person programs across racial/ethnic groups; for online programs, the men to women HRs were between 1.08 and 1.17. Among men in in-person programs who reported race/ethnicity, the largest HR was found for those who identified as Hispanic/Latino vs. White (1.46). Regarding men in online programs, this was the only comparison where a racial/ethnic difference was seen (1.04). Dropout rates for women in in-person programs were different between all racial/ethnic groups except those who identified as Other vs. White. The largest HR was for those who identified as Hispanic/Latino vs. White (1.29). Women in online programs who identified as Black/African American or Other had lower rates than White women, both with HRs of 0.98.
Conclusion: As we strive to retain participants in the LCP to maximize reducing risk of type 2 diabetes, our data predicting retention for different populations may allow for more focused coaching.
