Abstract
Background: The Russian tobacco control law (TCL), implemented nationwide, aims to reduce smoking-related morbidity and mortality. However, its effects may vary among Russian regions. We aimed to assess the effects of TCL on rates of hospital admissions (HA) for angina pectoris (AP) and myocardial infarction (MI) in the Russian Federation (RF) and 10 Russian regions in relation to enforcement of the TCL. Methods: We analysed HA rates for AP and MI to compare the periods before and after TCL in 2013, adjusting for possible confounders and long-term trends. Models were based on time-series of annual HA in the RF and 10 Russian regions during the years 2005-2019. We used interrupted time-series design and Poisson regression model with calculation of risk ratio (RR) and 95%CI. Regions were compared by means of TCL implementation scale (TCIS), developed based on the results of Russian TC policy evaluation survey in 10 Russian regions (n = 11625). We analysed the relationship between the TCL measures implementation scores and RR of reduction of HA for AP and MI after the TCL by means of Spearman’s rank correlation and linear regression models. Results: Results showed a 16.6% decrease in HA rates for AP (RR 0.83 95% CI 0.74-0.93) and 3.5% - for MI (RR 0.96 95% CI 0.96- 0.97) after the TCL introduction in RF and effects of various magnitude in the regions. Regions with higher TCIS scores, i.e. better enforcement of full TCL package had greater reduction in HA rates for AP (rsp = 0.627 95%CI1.05;0.199; p=.004); with better enforcement of smoke-free policies - grater reduction in HA rates for MI (rsp = 0.793 95%CI1.08;0.506, p<.001). Both HA rates for AP and MI correlated with the higher scores for help to quit tobacco use (rsp = 0.56 95%CI 1.1; 0.01, p=.045), (rsp = 0.74 95%CI1.12;0.36, p=.027). Conclusions: TCL leads to a decrease of HA for AP and MI with sustained effect. Differences in the magnitude of these effects in the regions are related to the extent of enforcement of TC measures. Key messages: Tobacco control legislative measures may lead to reduction of hospital admission rates for acute coronary events. The effect of tobacco control law on hospital admission rates for acute coronary events may vary in relation with the extent of enforcement of tobacco control measures.
