Regional surveillance of social and geographic inequalities in smoking: the case of Montréal, Canada.
Surveillance of social inequalities in health is a platform for action. We examined the trends in smoking behaviours (current and ever smoking, quit ratios) according to education and place of residence and we quantified the observed inequalities. Data were from repeated cross-sectional surveys (2003-2009) of Montreal (Canada) residents ≥15 years (n=12,053). Trends in smoking behaviours according to education were measured with logistic and log-binomial regressions. Spatial distribution of smoking behaviours across local areas was assessed with Morans' Index. Observed inequalities were quantified with prevalence ratio and difference, population attributable risk, and slope index of inequality. Results showed that ever smoking rose among low-educated individuals. Among their high-educated fellow-citizens, current smoking decreased and quit ratios increased. Adverse smoking behaviours (current and ever smoking) were clustered in south-central areas. We conclude that smoking inequalities in Montreal are growing. We thus encourage a closer monitoring of smoking social differentials.
