  1. Means ± standard errors of each variable are shown. Age and habit of regular exercise were used as other explanatory variables in ANCOVA. In addition, habit of alcohol drinking was added to the explanatory variables for analysis of overall participants (non, occasional and regular drinkers) and drinking participants (occasional and regular drinkers). LDL-C/HDL-C, ratio of LDL cholesterol to HDL cholesterol; TG/HDL-C, ratio of triglycerides to HDL cholesterol. Asterisks denote significant differences from nonsmokers. *, p < 0.05; **, p < 0.01
