Factors associated with attempting and succeeding in smoking cessation following a National Tobacco Control Plan: Analysis of two nationwide surveys (2010 and 2017)

Introduction: Lower rates of smoking cessation among disadvantaged groups contribute to widening health -disparities. With this recognition, in 2010 free-of-charge/subsidized smoking cessation services became avail-able to all Israeli residents through the not-for-profit health plans.Methods: Based on two cross-sectional National Social Surveys, data on adult ever-smokers were used (n = 2,998 in 2010 and 2,859 in 2017). The outcome variable comprised three categories: no quit attempt, unsuccessful quit attempt and successful quit attempt. Changes over-time and demographic, socioeconomic, health-and smoking -related factors associated with quitting attempts and success were tested in the pooled sample, using multi -variable multinomial logistic regression models.Results: The pooled sample of the two surveys included 2,611 participants (44.2%) who were successful quitters, 1,941 (32.7%) who reported an unsuccessful quit attempt, and 1,305 (23.1%) smokers who did not attempt to quit. Compared to 2010, ever-smokers in 2017 were less likely to report an unsuccessful quit attempt (adjusted OR = 0.81, 95%CI: 0.70-0.94). The likelihood of successfully quitting was similar in both surveys. Older age and self-reported health problem were associated with higher likelihood of quitting attempt. Meeting living expenses, being overweight/obese, engaging in physical activity and heavy smoking were associated with higher likelihood of successful smoking cessation; while environmental tobacco exposure was associated with 43% lower likelihood of successful cessation. Finally, there was an interaction between education and ethnicity. Higher education level was associated with a greater likelihood both to attempt to quit smoking and to succeed among Jewish participants, while the opposite phenomenon was observed among Arab smokers.Conclusions: Despite the availability of subsidized smoking cessation services, social disparities in smoking cessation rates persist. Efforts should focus on proactively reaching subpopulations with low cessation rates, using tailored strategies for successful smoking cessation. Promoting smoke free homes and workplaces should be prioritized.

Despite the availability of subsidized smoking cessation services in Israel, social disparities in smoking cessation rates persist. Efforts should focus on reaching subpopulations with low cessation rates and using tailored strategies for successful smoking cessation. Prioritizing smoke-free homes and workplaces is also important.
