ABSTRACT

Objective: To understand the prevalence and influencing factors of tobacco dependence among the population aged 15-69 in Tianjin to provide the basis for formulating targeted smoking control intervention policies and carrying out scientific smoking cessation intervention services. Methods: The data of this study comes from the 2018 Tianjin residents' health literacy monitoring survey. Probability-proportional-to-size sampling is adopted for sampling. SPSS 26.0 software was used for data cleaning and statistical analysis, and χ2 test and binary logistic regression were used to analyze the influencing factors. Results: A total of 14 641 subjects aged 15-69 were included in this study. After standardized, with a smoking rate of 25.5%, including 45.5% for men and 5.2% for women. Among the population aged 15-69, the prevalence of tobacco dependence was 10.7%; among current smokers, the prevalence rate of tobacco dependence is 40.1%, of which the prevalence rate of male tobacco dependence is 40.0%, and the prevalence rate of female tobacco dependence is 40.6%. According to multivariate logistic regression analysis, people who live in rural areas, have an education level of primary school or below, smoke every day, smoke the first cigarette ≤15 years old, smoke ≥21 cigarettes per day, and smoke for more than 20 packet years, people who report poor physical health are more likely to suffer from tobacco dependence (all P<0.05); age and smoking age did not affect the possibility of tobacco dependence (all P>0.05). Among current smokers, there was no significant difference in their willingness to quit smoking whether they had tobacco dependence (P>0.05). The proportion of people with tobacco dependence who have tried to quit smoking and failed is higher (P<0.001). Conclusions: The prevalence of tobacco dependence among smokers aged 15-69 in Tianjin is high, and the demand for quitting smoking is great. Therefore, smoking cessation publicity should be carried out for key groups, and smoking cessation intervention work in Tianjin should be continuously promoted.
