Müller, S., Kraus, L., Piontek, D. & Pabst, A. (2010). Changes in exposure to second hand smoke and smoking behaviour in the general population after the introduction of new smoke-free laws in Germany [Veränderungen in der Passivrauchexposition und im Rauchverhalten nach Einführung der Nichtraucherschutzgesetze in Deutschland]. Sucht, 56 (5), 373-384.
|Aims : This study examines exposure to secondhand smoke and smoking behavior in the German general population before and after the introduction of new smoke-free laws between 2007 and 2008.|
Methods : Data came from the 2006 and 2009 German Epidemiological Survey of Substance Abuse (ESA). A propensity-score-matched subsample of N=7,412 subjects between 18 and 64 years was used for the analysis. We employed multinomial logistic regression to examine changes in exposure to secondhand smoke at work, during leisure time and at home among non-smokers between 2006 and 2009. Logistic and ordinary least square regression were used to address changes in cigarette smoking prevalence and number of cigarettes smoked.
Results : Exposure to secondhand smoke at work and at leisure time was substantially reduced in 2009 compared to 2006. The number of cigarettes smoked decreased in the same time period. No changes were found for exposure to secondhand smoke at home and cigarette smoking prevalence. However, sensitivity analysis revealed moderate stability of the results for exposure to secondhand smoke at home and number of cigarettes smoked.
Conclusions : Results indicate that smoke-free laws constitute an important step forward in the protection of nonsmokers in Germany. Moreover, our findings suggest that specific preventive action is still needed to reduce cigarette smoking prevalence.
