In recent decades, large increases in diabetes prevalence have been demonstrated in virtually all regions of the world. The management of DM depends on the patient’s ability to do self-care in their daily lives, and therefore, patient education is an essential element of DM management. Health literacy is directly related to health management.

Combine healthy literacy to evaluation Conversation Maps. The tools can improve the nutritional knowledge, healthy eating behavior of diabetic patients (especially low healthy literacy), and the biochemical indicators on HbA1c and BMI.

Results: A total of 85 patients with type 2 diabetes in this study.40 in the intervention group and 45 in the control group. The results showed that the Conversation Maps improve the nutritional knowledge (F=4.08, P=0.047), and healthy behavior (F=16.44, P<0.001). After three months intervention the HbA1c ( F=5.20, P=0.03) and six months (F=0.06, P=0.81) no significant difference. By the way, three months (F=0.70, P=0.41) and six months (F = 1.76, P = 0.19) also no significant differences in the BMI. The low healthy literacy (F = 0.11, P = 0.75) no significant differences too.

Conclusion：Compared with traditional education, Conversation Maps promote the nutrition knowledge and eating behaviors of diabetic patients effectively.
