  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). WC, waist circumference; WHtR, ratio of waist circumference to height; TG, triglycerides; HDL-C, HDL cholesterol; LDL-C, LDL cholesterol. Asterisks denote significant differences from nonsmokers. *, p < 0.05; **, p < 0.01
