The purpose of this study was to identify factors affecting glycated hemoglobin A1c (HbA1c) in Korean middle-aged and older adults. Subjects were adults aged 40 and older (4,718 normal range of HbA1c, 4,695 prediabetes and 1,592 diabetes) who drawn from the 6th (2013∼2015) National Health and Nutrition Examination Survey. Data were analyzed by complex samples analysis with SPSS 24.0 program. The most important factor on prediabetes and diabetes was current smoking, and others revealed as old-aged, higher waist circumference, higher triglyceride, lower hemoglobin, and higher fasting plasma glucose (R2 = 0.489). Identification of influential factors of hemoglobin A1c may contribute to the early detection of patients who are susceptible to diabetes and may also be contributed to plan interventions to lowering hemoglobin A1c. In addition, monitoring of hemoglobin A1c levels and clinical laboratory indicators can be used as an indicator to monitor diabetic complications and other health problems.
