Abstract

Introduction: Smoking remains one of the biggest public health challenges worldwide, quitting tobacco smoking can lead to substantial health gains, even later in life. Previous studies indicate that illness can be a powerful motivation to quit and physicians' advice on smoking cessation has been shown to improve quit rates, but evidence on the role of non-communicable diseases in smoking cessation is limited. This cross-sectional study aims to evaluate the prevalence of non-communicable diseases and to explore its role in smoking cessation intention in smokers in Shanghai.

Methods: From January to June 2021, 1104 current smokers were recruited in the Songjiang and Fengxian districts of Shanghai. We used an Android assisted electronic questionnaire for data collection, and implemented logistic regression for odds ratio (OR) and 95% confidence interval (CI) calculation to explore how smoking cessation intention would be influenced by non-communicable diseases comorbidity among smokers.

Results: The 1104 current smokers included 914 males (82.8%), with an average age of 43.6 years. Approximately 22% of smokers had at least 1 type of non-communicable disease, with 17.8% for non-respiratory system related non-communicable diseases and 6.6% for respiratory system related non-communicable diseases. The prevalence of non-communicable diseases comorbidity ranged from 0.5% to 13.9%, and was higher in male smokers; 41.8% of current smokers had intention to quit smoking in a recent year, and the percentage of smoking cessation intention was higher in smokers with non-communicable diseases. Logistic regression indicated that smokers with non-communicable diseases had 1.3 (95% CI: 1.0-1.8) times higher smoking cessation intention than those without non-communicable disease. The findings were consistent in respiratory system related and non-respiratory system related non-communicable diseases.

Conclusions: The prevalence of non-communicable diseases was high among current smokers in Shanghai, and their smoking cessation intention was associated with non-communicable diseases comorbidity. Physicians should treat illness as a powerful motivation and provide professional cessation service to tobacco users to reverse the severe tobacco epidemic.
