† Odds Ratios and 95% confidence intervals are given for smoking prevalence, initiation ratio, and quit ratio, Bètas and 95% confidence intervals for smoking consumption. All regression coefficients were adjusted for age group. Regression coefficients in italics were non-significant.

* Education level and income level were entered as independent variables in separate analyses.
