Model of healthcare utilization based on the Andersen and Aday conceptual framework23 and adapted to the study of race‐sex differences in statin utilization and LDL‐C control among REGARDS participants with diabetes mellitus and high cholesterol. This conceptual model shows that predisposing factors influence enabling factors, which in turn influence perceived and evaluated need factors.
