The incidence of type 2 diabetes in people under 30 rose 2.2 times, from 27.6 to 60.5 cases per 100,000. Even more striking, its prevalence quadrupled, climbing from 73.3 to 270.4 per 100,000. While the incidence of type 1 diabetes remained relatively stable, its prevalence more than doubled, increasing from 21.8 to 46.4 per 100,000.
The analysis revealed clear gender differences: type 1 diabetes showed a 26% higher prevalence among females, whereas type 2 diabetes was 17% more common in males. Age-specific trends indicated that type 1 diabetes rose most sharply in infants and young children (ages 0–5), while type 2 diabetes increased most prominently among adolescents (ages 13–18).

Socioeconomic disparities were striking—prevalence of type 1 diabetes was 2.9 times higher and type 2 diabetes 3.7 times higher in low-income groups compared to middle- and high-income groups.
The findings highlight the growing burden of diabetes among South Korea’s youth, signaling the need for targeted public health strategies to address this rising trend.
