This study analyzed the Korea National Health and Nutrition Examination Survey data from 2007 to 2017 to assess trends in prevalence, treatment, and control of diabetes in Korean adults ≥30 years of age.
Prevalent diabetes was defined as fasting plasma glucose level ≥ 126 mg/dl, self-reported use of antidiabetic treatment (insulin or oral anti-diabetic drugs), or diabetes diagnosis by a physician. Target levels were defined as glycosylated hemoglobin <6.5% or <7.0%, blood pressure <130/80 mmHg, and total cholesterol <200 mg/dl. All survey waves were age-standardized to the 2005 Korean census population.
Diabetes prevalence increased from 9.6% in 2007-2009 to 10.8% in 2016-2017 (p<0.001). Impaired fasting glucose prevalence significantly increased in both sexes and almost every age group. Diabetes awareness and glycemic control did not show an increasing trend; however, the treatment rate and proportion of people diagnosed with diabetes achieving blood pressure and total cholesterol target levels improved from 57.2% to 63.5% (p=0.008), from 41.1% to 53.2% (p<0.001), and from 65.0% to 78.0% (p<0.001), respectively.
From 2007 to 2017, the prevalence of diabetes increased moderately in Korea whereas the diabetes treatment rates as well as the proportion of people diagnosed with diabetes achieving blood pressure and total cholesterol target levels improved. However, awareness of diabetes and the levels of glycemic control all require significant improvements. A national-level action plan is required to raise awareness about diabetes and prediabetes towards improving glycemic control and minimizing the occurrence of adverse health outcomes.
