Predictors of Smoking Cessation Attempt and Continued Abstinence among Low-Income Disabled Smokers: Evidence from the French National Smoking Cessation Cohort CDT-Net

Background: In France, daily smoking has been highly prevalent among low-income smokers. Objectives: Our aim was to search for factors associated with both continued abstinence and attempting to quit among low-income disabled smokers. Methods: From the French national smoking cessation cohort CDT-net, we included 1624 adults living with disability pension or disabled adult allowance. Our dependent variables (abstainers, attempting to quit among non-abstainers) were used in logistic regressions. Continued abstinence was defined as self-reports of no smoking for more than 28 days and attempting to quit was defined as self-reports of no smoking for less than 28 days; both validated with carbon monoxide < 10 ppm. Results: The average age was 48.5 years, with a predominance of men (55.5%). Achieved continued abstinence was 29.9% and was positively associated with age >= 55, history of previous attempts, low-dependence, and number of consultations during follow-up (all p < .05). Depression history, anxiety symptoms and cannabis use were negatively associated with continued abstinence (p < .05). Quit attempts were associated with lower dependence and number of consultations during follow-up. Pharmacological treatments prescribed at inception did not contribute to improve continued abstinence rates but varenicline was found to increase quit attempts unless the number of prescriptions was scarce. Conclusion: Even among low-income disabled smokers, achieving continued abstinence and attempting to quit could be promoted with similar predictors than among affluent smokers. Treatment of anxiety symptoms and specific support for smokers with a depression history could be included in the follow-up of quit attempts.
