[Analysis of tobacco use situation and related factors among occupational population in Beijing in 2018].

Objective: To understand the tobacco use situation and related factors among the occupational population in Beijing in 2018. Methods: The data were obtained from a special survey on "Healthy Beijing People-Ten-year Action Plan for Health Promotion (2009-2018)". From June to September 2018, 12 908 participants were recruited from 16 districts of Beijing using the stratified sampling method combined with the typical sampling method. Questionnaires were conducted to collect basic information, work situations, tobacco exposure in public places, and smoking cessation. The Chi-square test was used to compare the differences in current smoking rates, smoking cessation rates and second-hand smoke exposure rates among participants with different characteristics. Multivariate logistic regression analysis was used to analyze the related factors of tobacco use. Results: The present smoking rate of the occupational population in Beijing was 18.0% (95%CI: 17.3%-18.7%), and the passive smoking exposure rate of non-smokers was 61.0% (95%CI: 60.1%-61.9%). The smoking cessation rate among the working population was 22.2% (95%CI: 20.7%-23.7%), and the proportion of current smokers with the intention to quit was 63.9% (1 485/2 325). The present smoking rate of employees of different genders, ages, education levels and occupational nature showed statistically significant differences (P<0.05). The results of multivariate logistic regression analysis showed that in males, compared with the age group of 16-29 years old, the risk of smoking increased in the age groups of 30-39 years old, 40-49 years old and over 50 years old [OR (95%CI) values were 1.49 (1.27-1.74), 1.34 (1.13-1.59) and 1.30 (1.06-1.59)]. Compared with those with junior high school or lower education, participants with high school/vocational/college education group had a higher risk of smoking (OR=1.38, 95%CI: 1.13-1.69), while those with master's degree or above had a lower risk of smoking (OR=0.30, 95%CI: 0.22-0.42). The physical workers (OR=1.28, 95%CI: 1.11-1.47) had a higher risk of smoking than the mental workers. Conclusion: The current smoking rate among the occupational population in Beijing is lower than the national level during the same period, but the exposure rate to second-hand smoke is relatively high. Age, educational level, job nature and gender are related factors of smoking.
