Effect of cigarette smoking on lipid profile: Analysis of mass screening of 29 519 middle-aged Japanese men
We perform annual health check-ups of company employees in order to determine those at high risk for atherosclerosis. The results of blood tests for lipid profile (total cholesterol, high-density lipoprotein cholesterol, triglycerides, fasting blood sugar and uric acid) in men aged ≥ 40 and < 60 were analysed according to the number of cigarettes smoked, divided into non-smokers (13 253 men), light smokers (1–19 cigarettes per day; 6836 men) and heavy smokers (≥ 20 cigarettes per day; 9430 men). The results are shown in the table. The concentration of triglycerides was correlated with smoking, as heavy smokers had a significantly higher concentration than the other two groups, and the concentration of high-density lipoprotein cholesterol was inversely related to smoking, non-smokers having the highest concentration. The concentrations of total cholesterol, fasting blood sugar and uric acid were correlated with body mass index rather than smoking.
