Confidence Intervals of each indicator were used to evaluate for difference between groups. Logistic regression was used to explore the potential factors associated with smoking in youths. RESULTS: The overall attempted smoking rate of the three cities was 26.2% (95%CI: 23.6 - 29.1), with male as 39.9% and female 12.5% respectively. The current smoking rate was 12.5% (95%CI: 11.1 - 14.2) with boys as 21.9% and girls as 3.2%. The smoking rate were different among three kinds of schools, with vocational school was the highest (25.8%), followed by senior high (7.9%) and junior high (6.3%).
