Relationship Between Diabetes Knowledge, Glycemic Control, and Associated Health Conditions.

Objective: The purpose of this study was to identify any existing relationship between diabetes knowledge and glycemic control, as well as possible associations with patient health, among patients with type 2 diabetes.

Design And Methods: This qualitative study used a validated multiple-choice test (the Michigan Diabetes Knowledge Test) to assess diabetes knowledge among 17 hospital patients between the ages of 18 and 75 years with type 2 diabetes and a recent (within 3 months) A1C laboratory value. Participants also provided information about their diabetes self-care habits, previous diabetes education, and diabetes-related secondary health conditions.

Results: The average diabetes knowledge score was 8.4 of 14 (60%), and the average A1C was 9.3%. Thirteen participants had previously received diabetes education, whereas four participants had never received diabetes education. The participants who had not received education scored 15.3% lower on the diabetes knowledge test and had an average A1C 0.89% higher than those who had received previous education. Although this difference was not statistically significant, it is clinically relevant. There was a significant association between diabetes knowledge and presence of retinopathy ( = 0.03).

Conclusion: Diabetes self-management education and support is a crucial component of diabetes care. There is a considerable need for diabetes education strategies to improve self-management of diabetes and thereby improve outcomes and decrease the costs of diabetes-related care. There is also a need for efforts to ensure regular vision screenings for individuals with type 2 diabetes.
