Kim, Kim, Lim, Jeong, Son, Chung, Koh, Lee, Won, Park, Park, Ahn, Kim, Park, Ko, Ahn, and Lee: Prevalence of the Metabolic Syndrome in Type 2 Diabetic Patients

Abstract

Background

The aim of this study was to analyze the prevalence of metabolic syndrome in Korean type 2 diabetic patients.

Methods

A total of 4,240 diabetic patients (male 2,033, female 2,207; mean age 58.7 ± 11.3 years; DM duration 8.9 ± 7.6 years) were selected from the data of endocrine clinics of 13 university hospitals in 2006. Metabolic syndrome was defined using the criteria of the American Heart Association/National Heart Lung and Blood Institute and the criteria of waist circumference from the Korean Society for the Study of Obesity.

Results

The prevalence of metabolic syndrome was 77.9% (76.7% of males, 78.9% of females). The average number of the components of metabolic syndrome was 2.4 ± 1.1. Abdominal obesity was seen in 56.8% of the patients, hypertriglyceridemia in 42.0%, low HDL cholesterol in 65.1%, and high blood pressure in 74.9%. Abdominal obesity and high blood pressure were much more prevalent among females than males, and low HDL cholesterol was much more prevalent among males than females. The prevalence of metabolic syndrome was not different according to the duration of diabetes. Metabolic syndrome was strongly related with obesity (odds ratio, 6.3) and increased age (odds ratio in the over 70 group, 3.4).

Conclusion

The prevalence of metabolic syndrome was 77.9% in Korean type 2 diabetic patients. Its prevalence was greater in obese patients and in those over 40 years of age.
