Background: Diabetes is accompanied by complications. One of the chronic complications, diabetic retinopathy is themost common cause of the loss of eyesight and thus has enormous impacts on the quality of life to the patients. It hasbeen reported that thorough glucose regulation can prevent or postpone the outset of diabetic retinopathy in diabeticpatients and that the patients who received anti-diabetic manage & care education would be capable of more thoroughglucose-level regulation than those who did not. Method: This study set out to investigate the current state of educationon anti-diabetic manage & care in South Korea and connections between anti-diabetic manage & care educationand occurrence of diabetic retinopathy in diabetic patients based on the Korea National Health and Nutrition ExaminationSurvey of 2011. Results: Of the 410 diabetes patients, 74 received anti-diabetic manage & care education, whichmeans that only 15% of diabetic patients benefited from the education in the nation. The occurrence rate of diabetic retinopathywas 28% in the education group and 24% in the non-education group with no significant differences betweenthem. The anti-diabetic manage & care education group recorded a higher occurrence rate of diabetic retinopathy, oneof the chronic diabetic complications, than the non-education group contrary to the hypothesis. One of the reasons wasthat the educated group had a significantly longer duration of diabetes and significantly higher HbA1c than the noneducatedgroup, which indicates that anti-diabetic manage & care education is provided to those who have progressedfarther along the course of diabetes instead of the early stage and cannot regulate their glucose-level well in the nation. Conclusion: Those findings raise a need for active educational policies in order to provide anti-diabetic manage & careeducation under the goals of preventing complications through anti-diabetic education for many patients in early stagesof diabetes.
