Sociodemographic, Clinical, and Psychosocial Predictors of Short- and Long-term Study Retention in the Diabetes Prevention Program (DPP) Outcomes Study (DPPOS).

ABSTRACT:

Objective

Success of longitudinal studies depends on retention of participants. We examined characteristics as predictors of retention among participants with prediabetes and type 2 diabetes (T2D) in the Diabetes Prevention Program (DPP) and the follow-up DPP Outcomes Study.
