Abstract

This study aimed to assess trends in the prevalence, treatment, and control of diabetes according to the socio-economic level in Korean adults aged ${\geq}30$ years, using the 2007-2017 Korea National Health and Nutrition Examination Survey data. Socio-economic status was assessed based on the household income. Multivariable logistic regression and predictive margins were used to evaluate the adjusted proportion of diabetes prevalence, awareness, treatment, and adequate glycemic control. During 2007-2017, the socio-economic inequalities on diabetes prevalence were observed in both men and women. However, the gradient of inequality increased only in men (p for interaction=0.034). Diabetes awareness, treatment, and control did not show socio-economic inequalities or increasing gradients in both sexes. Monitoring of these trends should be continued, and further research on effective interventions is needed.
