Abstract:
The purpose of this study was to investigate the association between insulin resistance and cardiovascular disease risk factors in Korean type 2 diabetes patients. The subjects were 429 (male :218, female :211 )type 2 DM patients visited DM clinic, and they were classified into quartiles based on KITT index (%/min, Insulin Tolerance Test ). Anthropometric and biochemical characteristics, and dietary intakes by Food Frequency Questionnaire were assessed. The means of waist circumference, fat mass, percent body fat and abdominal fat thickness were significantly higher in the lowest quartile (the most insulin resistant group )than in the highest quartile (the least insulin resistant group )of KITT index (%/min )(p < 0.05 ). For hematological values, the lowest quartile showed significantly higher fasting blood glucose, HbA1c, C-peptide, insulin, triglyceride, ApoB/apoA-1 ratio and C-reactive protein compared to the highest quartile (p < 0.05 ). Moreover, KITT index (%/min )was negatively correlated with waist circumference, fat mass, percent body fat, abdominal fat thickness and fasting blood concentrations of glucose, HbA1c, C-peptide, insulin, cholesterol, triglyceride, ApoB/apoA-1 ratio and C-reactive protein (p < 0.05 ). Nutrient intakes were not significantly different among the quartile groups of KITT index (%/min )and also not correlated with insulin resistance, however, they showed correlation with obesity parameters (BMI, waist circumference, waist-hip ratio, vat mass, abdominal fat thickness ), which were strongly associated with insulin resistance. In conclusion, cardiovascular disease risk would be higher as the insulin resistance grows in Korean type 2 DM patients, and nutrient intakes would affect to the insulin resistance through the effect on anthropometric parameters.
