title: Illness and treatment perceptions are associated with adherence to medications, diet, and exercise in diabetic patients.
abstract: OBJECTIVE
  To investigate diabetic patients' perceptions of illness and treatments, and explore relationships to adherence and blood glucose control.
  
  
  METHODS
  Forty-nine type 1 and one hundred and eight type 2 diabetic patients completed questionnaires assessing illness perceptions, treatment beliefs, and adherence to medications, diet, and exercise. Blood glucose control was assessed from blood tests.
  
  
  RESULTS
  Patients rated medication more important than diet and exercise, and reported higher adherence to medications. Insulin was perceived as more helpful for diabetes, while antihypertensives and cholesterol medication were perceived more helpful for preventing heart problems. Perceptions were associated with adherence to insulin, cholesterol and antihypertensive medications, exercise, and diet. Blood glucose control in type 1 diabetic patients was associated with insulin adherence and perceived personal control, and in type 2 diabetic patients to being prescribed insulin or antihypertensives, and perceived personal control.
  
  
  CONCLUSIONS
  Patients hold specific mental models about diabetes treatments, which are associated with adherence.
