Objective: Vitamin D insufficiency is known to be related to cardiometabolic disorders; however, the associations among serum Results: Vitamin D insufficiency, defined as 25(OH)D concentration ,50 nmol/l, was found in 75?3 % of Korean adolescents and was associated with an increased risk of the prevalence of metabolic syndrome. Waist circumference and BMI were the most closely correlated cardiometabolic components of metabolic syndrome according to serum 25(OH)D status, but no significant relationship was found between serum 25(OH)D concentration and insulin resistance or for the risks for high blood pressure, hyperglycaemia, reduced HDL-cholesterol or hypertriacylglycerolaemia, with or without adjustment for confounding variables. Conclusions: Low serum 25(OH)D concentration appears to be associated with several cardiometabolic risk factors and an increased risk of the prevalence of metabolic syndrome in Korean adolescents.

Our study showed favorable trends in the prevalence of dyslipidemia and in several lipid profiles among Korean adults.
