Age-adjusted prevalence and 95% CI were derived from a logistic regression model including age.
Recent successful cessation was defined as the percentage of former smokers who had last smoked a cigarette within the previous year, but not within the 6 months prior to the survey among current smokers and former smokers who quit within the past year.
Adjusted prevalence ratio and 95% CI were derived from a logistic regression model including all other selected characteristics.
Unreliable estimates when relative standard error>0.30 or N<50.
