Changes in tobacco use patterns and motivation to quit related to the new smoke-free legislation in the Czech Republic
Abstrakt
Background: Smoke-free policy belongs to key public health instruments to promote health in populations. In 2017, new comprehensive smoke-free law prohibiting smoking in indoor public places was implemented.
We aimed to measure changes in tobacco smoking patterns and changes in motivation to quit in adult smokers prior to and after the new smoke-free legislation came into force. Methods: We conducted a prospective cohort study prior to and post the implementation of Act No. 65/2017 Coll.
Self-reported questionnaires were administered to 131 adult smokers by trained nurses in general practitioner offices in Prague. We analysed changes in cigarette consumption per day; ratio of cigarettes smoked in pub, street, work and home; and motivation to quit using regression modelling.
Results: We found a statistically significant decrease in the daily consumption of cigarettes (an average of 1.7 cigarettes per day, P < 0.001, d = 0.34). Smoking in indoor public spaces decreased to almost zero, while tobacco consumption in outdoor public spaces (such as streets and squares) increased by nearly 20%.
We observed statistically significant increase of motivation to quit smoking (P = 0.021, d = 0.21). Conclusion: The study brings valuable indication of the desired public health impact related to key legislative change in the Czech Republic.
