Abstract:

Objective: To understand the effects of smoking cessation on respiratory symptoms and chronic respiratory diseases among rural male residents in 7 counties of the Huaihe River Basin, which might provide scientific evidence for tobacco control and health promotion in rural China. Methods: From November 2015 to October 2018, participants aged 20-70 from 7 counties of Huaihe river basin were selected with purposive sampling and household interview for every participant was completed using self-designed questionnaire by uniformly trained investigators. Totally 1583 male participants were included. Logistic regression model was used to analyze the effects of smoking or smoking cessation on respiratory symptoms and chronic respiratory diseases. Results: The smoking rate was 49.3% (781/1583), and the smoking cessation rate was 26.3% (278/1059). Compared with current smokers, ex-smokers showed a lower risk of cough (OR=0.62, 95%CI: 0.43-0.89). The ex-smokers who quit smoking for non-health reasons had lower risks of cough (OR=0.51, 95%CI: 0.32-0.83), chronic cough (OR=0.20, 95%CI: 0.06-0.63) and expectoration (OR=0.54, 95%CI: 0.34-0.87) than those current smokers. For those ex-smokers who had been smoking ≥30 years, the risks of chronic expectoration (OR=3.11, 95%CI: 1.03-9.40) and wheezing (OR=5.73, 95%CI: 2.05-16.04) were significantly higher than those who had been smoking <30 years. Meanwhile, the risks of cough (OR=0.41, 95%CI: 0.20-0.81) and shortness of breath (OR=0.58, 95%CI: 0.37-1.00) for the ex-smokers who had quit smoking ≥3 years were significantly lower than those who had quit <3 years. Conclusion: Smoking cessation for non-health reasons was related to decreased risks of respiratory symptoms and chronic respiratory diseases for male smokers in rural Huaihe River Basin. The shorter the cumulative smoking year, the longer the smoking cessation period, the more obvious health benefits will be gained by smoking cessation.
