Relationship between food-frequency and glycated hemoglobin in korean diabetics: Using data from the 4th korea national health and nutrition examination survey

초록

Background: This study was performed to evaluate the association between food intake frequencies and long-term blood glucose control using glycated hemoglobin (HbA1c) in Korean diabetes. Methods: This study used data collected from the 4th Korea National Health and Nutrition Examination Survey. Patients with diabetes were defined as people who responded yes to the question Are you currently suffering from diabetes? or in whom serum fasting glucose was 126 mg/dL or more. Using the food frequency questionnaire and HbA1c in surveys, we examined the association between the annual food-frequencies of each food group and long-term blood glucose control. Results: After adjustment for other covariates, HbA1c decreased significantly as the frequency of the intake of fish increased in each population (P = 0.001 for all, P = 0.043 for men, P = 0.001 for women). The intake of mackerel played an especially important role in the control of diabetes. Among women, HbA1c decreased as the frequency of intake of legumes increased (P = 0.029) and increased as the frequency of intake of staple carbohydrates increased (P = 0.015). On the other hand, any intake of other food groups showed no significant relationship with HbA1c. Conclusion: Frequent intake of fish in all populations and legumes in woman were associated with good glycemic control in diabetics. Frequent intake of carbohydrates was associated with elevated HbA1c in women. ? 2012 The Korean Academy of Family Medicine.
