A Comparative Analysis on the Environmental and Dietary Factors in Korean Adult Males Classified by Serum Lipid Profiles

Abstract

The purpose of this study was to investigate the distribution patterns of serum triglyceride and cholesterol levels and the influence of environmental and dietary factors in 201 healthy male subjects. The subjects were found to be 53.7% for the normal, 15.4% for the TC, 17.4% for TG and 13.5% for TC.TG group, respectively. Among general characteristics, smoking significantly affected serum lipid levels of subjects (p<0.05). Among anthropometric factors, body weight, BMI and PIBW significantly influenced the blood lipid patterns. Body weight of TG group was significantly higher than that of normal group (p<0.05). BMI and PIBW of TG group and TC.TG group were significantly higher than those of normal group (p<0.05) . In addition, diastolic blood pressure of TG group was significantly higher than that of normal group (p<0.05). For the food intake, average intake of fruit was significantly higher in normal group than that of TG group (p<0.05). For nutrient intake, calcium intake was significantly higher in TC group than those of normal and TC.TG group (p<0.05). Intakes of vitamin B2 and C were significantly higher in TC group than those of in TG group (p<0.05). Serum HDL-cholesterol level was negatively related to meat, poultry, and their products (p<0.05), but serum total cholesterol level positively related to animal lipids (p<0.05). The results of this study suggest that it is crucial for maintaining adequate serum lipid levels to reduce smoking, blood pressure and to lose body weight. As far as food intake concerned, fruit intake was important in maintaining serum triglyceride level normal, while animal food intake affected serum total cholesterol level adversely.
