Abstract

Objectives
This study aimed to determine the time-series changes in provincial diabetes management indices using by results of the 2008-2022 Korea Community Health Survey.
Methods
We collected diabetes diagnosis experience rate, treatment rate for people diagnosed with diabetes, annual screening rate for diabetic eye disease complications, and annual screening rate for diabetic kidney disease complications with age-standardized rates from the Regional Health Statistics. The unit of analysis was the nation and 17 provinces and the time-series trend analysis was performed by joinpoint regression using the Joinpoint Regression Program, and the annual percent change (APC) and average APC (AAPC) were estimated, and statistical significance was tested using 95% confidence interval (CI).
Results
From 2008-2022, the national AAPC (95% CI) for diabetes diagnosis experience rate steadily increased to 2.77 (2.25-3.27), increasing in all regions, excluding Sejong. The national AAPC for treatment rate for people diagnosed with diabetes was 0.75 (0.47-1.04), with a slight but steady trend toward improvement, excluding Daejeon, Sejong, and Jeonbuk, which showed significant improvement. The national AAPCs for annual screening rates for diabetic eye disease and kidney disease complications were 1.82 (0.99-2.66) and 1.95 (0.60-3. 41), respectively, and the area with the largest change was Sejong.
Conclusions
In Korea, the diabetes management indices tended to increase and improve, but the trends among provinces varied. Therefore, efforts are needed to address regional disparities in diabetes management.
