Question 1: Do you think colorectal cancer is a common cancer? Question 2: Do you think this screening will help you improve your awareness of health? Question 3: Do you think this screening can find an early stage of colorectal cancer? Question 4: Do you think it is necessary to conduct the colorectal cancer screening in your community? Question 5: How do you know this screening program? Community means community screening center;
All single OR’s means without adjustment for any other factors in the model, and all multiple OR’s means with adjustment for the following factors including age (0 = < 45, 1 = 45-49, 2 = 50-54, 3 = 55-59, 4 = 60-64, 5 = 65-69, and 6 = ≥ 70), gender (0 = male and 1 = female), occupation (0 = worker, 1 = official/administrator, 2 = technician/professional, 3 = businessman, and 4 = others), interaction term between gender and occupation, and annual personal income (0 = < ¥10 000, 1 = ¥10,000-< 20 000, and 2 = ≥ ¥20 000); all variables were treated as dummy variables in the logistic regression model.
