This study was performed to clarify the overall inter-relationships between the arteriosclerotic risk factors, including smoking, alcoholic consumption, obesity, serum cholesterol and triglyceride levels, high density lipoprotein, and systolic and diastolic blood pressure using a meta analysis method. The subjects of this study were included in 24 primary studies reported in Korea since 1980, which concerned arteriosclerotic risk factors. The results show that smoking is significantly associated with total cholesterol (R = .04), triglyceride (R = .10) and HDL-cholesterol (R = -.06). Alcohol consumption is also significantly and positively associated with all three serum lipid parameters: cholesterol (R = .04), triglyceride (R = .08) and HDL-cholesterol (R = .10). The effect of smoking and alcohol consumption on cholesterol levels were found to be almost equal. However, smoking has a predominant effect on triglyceride, whereas, alcohol consumption exerts an influence primarily on the HDL-cholesterol level. Obesity was positively correlated with cholesterol (R = .25) and triglyceride (R = .21), however, it was negatively correlated with HDL-cholesterol (R = -.14). It appears that the serum lipid parameter, which shows strongest correlation with obesity, is the total cholesterol level. Obesity also showed a significant correlation with systolic (R = .19) and diastolic blood pressure (R = .13). Blood pressure was also positively correlated with cholesterol (R = .18) and triglyceride (R = .26), however, it correlated negatively with HDL-cholesterol (R = -.23). In conclusion, the overall inter-relationships between the arteriosclerotic risk factors; smoking, alcohol consumption, obesity, serum lipid level and blood pressure were all found to be significant.
