Effect of the comprehensive smoke-free law on time trends in smoking behaviour in primary healthcare patients in Spain: a longitudinal observational study.

Objective: This study aimed to analyse the impact of comprehensive smoke-free legislation (SFL) on the prevalence and incidence of adult smoking in primary healthcare (PHC) patients from three Spanish regions, overall and stratified by sex.

Design: Longitudinal observational study conducted between 2008 and 2013.

Setting: 66 PHC teams in Catalonia, Navarre and the Balearic Islands (Spain).

Effect of comprehensive smoke-free legislation on asthma and coronary disease trends in Spanish primary care patients.

Background: To examine the impact of comprehensive smoke-free legislation (SFL) (Law 42/2010) on the incidence and prevalence of adult asthma and coronary disease in primary health care (PHC) patients from three Spanish regions, overall and stratified by sex.

Methods: Longitudinal observational study conducted between 2007 and 2013 in the population over 15 years of age assigned to 66 PHC teams in Catalonia, Navarre and the Balearic Islands. Crude rates and age-standardized (truncated: asthma ≥ 16 years and coronary disease ≥ 35 years) incidence and prevalence rates using the direct method based on the European Standard Population were estimated based on data from PHC electronic health records.
