PEREZ-RIOS, Mónica et al. Impact of the Spanish smoking laws on the exposure to environmental tobacco smoke in Galicia (2005-2011). Gac Sanit [online]. 2014, vol.28, n.1, pp.20-24. ISSN 0213-9111.  https://dx.doi.org/10.1016/j.gaceta.2013.04.010.

Objective: Prevalence of exposure to environmental tobacco smoke is a valuable index to assess the impact of the laws for tobacco control. The objective of this work is to analyse variations in the prevalence of exposure to environmental tobacco smoke in Galicia (Spain) between 2005, before the Law 28/2005, and 2011, after the law 42/2010. Methods: Data were obtained from five population-based independent cross-sectional studies, telephone surveys, developed in Galicia between 2005 and 2011 among population aged 16 to 74 (n = 34.419). Self-reported exposure among population aged between 16 and 74 was analysed by setting and tobacco consumption by prevalence with 95% confidence intervals. Results: Environmental tobacco smoke exposure decreased dramatically in Galicia between 2005 and 2011. In 2005, before the Law 28/2005, 95% of the population reported exposure to environmental tobacco smoke compared to 28% in 2011, after the Law 42/2010. Decrease was greater in workplaces in 2006 and in leisure time venues in 2011. After an initial decrease in 2006, exposure at home remains unchanged. Conclusions: An important reduction in self-reported exposure to environmental tobacco smoke occurred in Galicia in the period 2005-2011, specially after the introduction of Laws 28/2005 and 42/2010. Nevertheless, one in four of the population aged 16 to 74 remained exposed in 2011.
