In Korean adults aged 30 and older, diabetes prevalence is 13.7% (4.8 million) and impaired fasting glucose (prediabetes) prevalence is 24.8% (8.3 million), with prevalence increasing significantly with age and lower family income.

If you are over 30, your risk of diabetes or prediabetes is significant, especially if you have lower income. Get screened regularly. Prediabetes (IFG) is highly prevalent and is a warning sign that lifestyle changes can prevent progression to full diabetes.

GoodSupportsHIGH confidence
The estimated population of diabetes in Korean adults (≥30 years of age) is 4.8 million, which represented 13.7% of this group in 2013 to 2014... The prevalence of IFG in adults aged 30 years or older was 24.8% (8.3 million)... The prevalence of diabetes was 1.4 times more common in subjects in the lowest quartile for family income (15.1%) than in the highest quartile (11.2%).

Why this rating

Based on a large, nationally representative cross-sectional survey (KNHANES) with rigorous statistical weighting, though cross-sectional design limits causal inference.
