Five-year Trajectory about Screening for Complication of Diabetes Kidney Disease and Cardiovascular Disease Mortality : Focusing on Regional Difference.

Backgrounds: The overall screening rate for complication of diabetes kidney disease is improving; however, regional variations are increasing. It is necessary to select regions vulnerable to change and understand their characteristics.

Methods: Group-based trajectory analysis was performed to derive change patterns in the complication of diabetes kidney disease screening rate in 244 regions using Community Health Survey data between 2015 and 2019. ANOVA test was conducted to examine the differences in regional characteristics and CVD in each change pattern.

Results: The change patterns in complication of diabetes kidney disease screening rate were classified into four groups: high and rapidly increasing (Group 1, 5.2%), steady high (Group 2, 8.2%), moderate and increasing (Group 3, 52.9%), and low and slightly increasing (Group 4, 23.8%). Group 4 had many rural areas and worse socioeconomic status, healthcare systems, health behaviors, and diabetes management, and these regions had higher CVD mortality rates.

Conclusions: Regions where the screening for complication of diabetes kidney disease rate did not improve compared to other regions were vulnerable not only in socioeconomic status, healthcare system, and health behavior, but also in disease management. This suggests the need for local and environmental support, as well as aggressive health service interventions in relatively vulnerable areas.
