Prevalence of smoking in Czech: mapping and comparison of the available data sources

Smoking is a risk factor in relation to health and the negative effects on health are already well known. Despite that, the prevalence of smoking is still relatively high, and smoking causes many deaths from various diseases associated with tobacco use. These deaths could be prevented by effective prevention. Monitoring tobacco use is key for effective prevention. Therefore, various international and national studies monitor tobacco use and their results often differ. In this work I compare available sources of data on smoking, which are implemented in the Czech Republic over the last almost thirty years. In this thesis, six repeated cross-sectional studies were analyzed. In order to compare studies with each other and the change over time, age-standardized prevalence of smoking was calculated for all studies analyzed. Binary logistic regression was used for more detailed comparisons. Furthermore, differences in social inequalities assessed based on education between the analyzed studies were identified. Statistically significant differences in the prevalence of smoking were found between the analyzed studies. Furthermore, different directions of trends in the development of smoking prevalence over time were also found in individual studies. A declining trend for both sexes was found only in the..
