Abstract´╝Ü Objective:To evaluate the change trend of smoking prevalence and the composition of main causes of death in Tianjin from 2010 to 2019.Methods:The study was based on the data collected in the Tianjin All Cause of Death Surveillance System from 2010 to 2019. A total of 699 372 cases were included in the study. The smoking prevalence, ex-smoking and never smoking prevalence were calculated according to different death years and gender. The proportion of smoking status was calculated according to the year of birth and gender. The distribution of smokers dying of smoking related diseases were calculated by different age-group. The change trend of smoking rate was analyzed by Joinpoint regression statistical software. The diseases that smokers died of were expressed by proportion.Results:From 2010 to 2019, the smoking rate of dead residents decreased from 28.7% to 21.4%, and the average annual change percentage (AAPC) was -3.0% (95% CI: -3.9%, -2.2%). The same trend was shown in dead residents of different genders. The proportion of ex-smokers showed an upward trend, from 10.5% in 2010 to 14.7% in 2019; The proportion of light smokers increased with the postponement of birth year. The proportion of light smokers born at and before year 1950 was 14.7%, while the proportion of light smokers born at and after year 1981 was as high as 85.9%; the proportion of heavy smokers decreased with the year of birth. Lung cancer and cardiovascular and cerebrovascular diseases were the main causes of death of smokers and quitters. 13.86% of quitters died of lung cancer, which was slightly lower than that of smokers (16.39%) and significantly higher than that of non-smokers (5.55%). With the increase of smoking degree, the proportion of smokers who died of lung cancer also increased gradually, from 9.19% to 19.11%. Conclusions:From 2010 to 2019, the smoking prevalence of dead residents in Tianjin shows a downward trend, which is consistent with the change trend of the overall smoking prevalence of residents in Tianjin. Lung cancer, acute myocardial infarction and ischemic heart disease rank among the top three causes of death among smokers.
