* Significant difference in prevalence of betel quid chewing by Chi-square analysis (p < 0.05). † Significant difference by logistic regression model (p < 0.05). a May not total 100% due to rounding. b Odds ratios (OR) refer to risk of betel quid chewers (including former chewers and current chewers) versus never chewers according to each variable. OR > 1 indicates a higher likelihood of being a betel quid chewer. c aOR: adjusted odds ratio for sex, age (years), obesity, education (years), marital status, ethnicity, alcohol consumption, and cigarette smoking by logistic regression model; 95% CI: 95% confidence interval. | ||||||
