Résumé
Introduction
Nicotine dependence may impede cessation, whereas major smoking-related disease may motivate quitting. We investigated their associations with sustained smoking cessation among middle-aged and older adults in China.
Methods
We analyzed four waves (2011, 2013, 2015, and 2018) of the China Health and Retirement Longitudinal Study (CHARLS). The sample included 2148 baseline cigarette smokers aged ≥45 years with complete Heaviness of Smoking Index (HSI) data and concordant smoking status in 2015 and 2018. Sustained cessation required no current smoking at both waves. The HSI scores (0-6) combined daily cigarette consumption and time to the first cigarette after waking. Major disease comprised heart disease, stroke, chronic lung disease, or cancer -multivariable logistic regression estimated mutually adjusted associations. Sensitivity analyses addressed missing data, attrition, outcome definition, nonlinearity, and smoking transitions.
