The Association of Plasma HDL-Cholesterol Level with Cardiovascular Disease Related Factors in Korean Type 2 Diabetic Patients

Abstract

Background: Cardiovascular disease (CVD) is the major cause of death in type 2 diabetic patients. The purpose of this study was to investigate the characteristics of Korean type 2 diabetes mellitus (DM) patients according to plasma high density lipoprotein (HDL) cholesterol level and to document the effect of diet on HDL-cholesterol. Methods: The subjects were 252 (male: 134, female: 118) Korean type 2 DM patients recruited from a general hospital's DM clinic and divided into low HDL-cholesterol group (male < 40 mg/dL, female < 50 mg/dL) and control group (male ≥ 40 mg/dL, female ≥ 50 mg/dL). Anthropometric and hematological variables and dietary intake were assessed by the groups. Results: The subject's mean age was 60.2 ± 1.1 years and duration of diabetes was 9.5 ± 1.0 years. Anthropometric measurements (body fat mass, % body fat, WHR, fat free mass, and muscle mass) and BMI were not significantly different between two groups. The male subjects with low HDL-cholesterolemia showed higher Atherogenic Index (AI, P < 0.001) and higher % carbohydrate from energy than control group (P < 0.01). The female subjects with low HDL-cholesterolemia showed higher AI (P < 0.001) and a tendency of higher triglyceride level and lower intake of energy, protein, lipid, vitamin B1 and vitamin E (P < 0.05) than control group. Conclusion: The subject with low HDL-cholesterolemia showed significantly higher AI. Male subject with low HDL-cholesterolemia consumed higher carbohydrate and female subject with low HDL-cholesterolemia showed lower intakes of many nutrients. This result suggests the importance of an adequate and balanced diet to manage type 2 DM patients to prevent CVD complications.(KOREAN DIABETES J 32:215-223, 2008)
