Abstract

Context: This study assessed the spatial dependence of daily tobacco consumption and how it is spatially impacted by individual and neighbourhood socio-economic determinants, as well as by spaces conducive to tobacco consumption before and after the implementation of a smoke-free policy.

Method: Individual data were obtained from the Bus Santé study, a cross-sectional survey conducted in Geneva. Spatial groupings of high and low tobacco consumption were determined using the Getis-Ord Gi* method.

Conclusions: Daily tobacco consumption was not randomly clustered in Geneva and could be impacted by spaces conducive to smoking, independently of socio-economic factors and a smoking ban. Spatial analysis should be taken into account to highlight the impact of smoke-free policies and guide public health interventions.
