Background Metabolic syndrome is a cluster of conditions including abdominal obesity, high blood pressure, elevated fasting glucose, high triglyceride, and low HDL-cholesterol. Up to now, there have only been a few studies about this disorder. Our aim was to show the prevalence and trends of metabolic syndrome in Korean children aged 10 to 18yrs using the Korean National Health and Nutrition Examination Surveys (KNHNES) administered in 2001 and 2005.
Methods The data for analysis were obtained from KNHNES 2001 and 2005. We analyzed 667 boys and 621 girls from KNHNES 2001 and 479 boys and 420 girls from HNHNES 2005.
Results The prevalence of metabolic syndrome in Korean children was 10.3% (boys 13.1%, girls 7.2%) in 2001 and 9.5% (boys 11.5%, girls 7.3%) in 2005. There was no significant increase in metabolic syndrome between 2001 and 2005. The numbers of children with high triglyceride and low HDL-cholesterol were especially higher than the other risk factors of metabolic syndrome in both 2001 and 2005. The prevalence of metabolic syndrome increased significantly with the increase in body mass index (OR = 1.42 in 2001, OR = 1.58 in 2005, P < 0.001), and leukocytes (OR = 1.33, P = 0.001)
Conclusions The prevalence of metabolic syndrome in Korean children was 10.3% in 2001 and 9.5% in 2005. With the rise in the prevalence of metabolic syndrome, especially in obese children, the prevention and management of metabolic syndrome risk factors in young children will be a critical focus of public health and clinical practice.
