Gradual versus abrupt quitting among French treatment-seeking smokers
Menée en France auprès de 28 156 fumeurs adultes ayant participé à des séances d'aide au sevrage tabagique entre 2007 et 2010, cette étude évalue les taux de participants ayant arrêté de fumer progressivement ou brusquement, puis identifie les facteurs prédictifs associés à un sevrage tabagique progressif
Objective : This study examined the prevalence and predictors of gradual quitting among treatment-seeking smokers. Method : This study examined quit attempts among 28,156 adult smokers who attended French smoking cessation services nationwide between 2007 and 2010. Predictors of gradual quitting were determined using multivariate regression models. Results : Only 4.4% quit gradually whereas 48.7% quit abruptly and 46.9% continued smoking. 34.1% of abrupt quitters and 31.9% of gradual quitters were abstinent at 1 month post-quit (p = 0.108). Gradual quitting was associated with: older age, heavy smoking at baseline, no previous quit attempts, low self-efficacy, baseline intake of anxiolytics, symptoms of depression and history of depressive episodes. Gradual quitters had a similar anxio-depressive profile than continued smokers but were more educated and more likely to have reported previous quit attempts. Prescription of oral nicotine replacement therapy (NRT) only as opposed to combination NRT doubled the odds of gradual quitting. Likelihood of gradual quitting compared with continued smoking improved with the number of follow-up visits. Conclusion : Our findings suggest that hard-to-treat smokers may be more likely to quit gradually than abruptly. However, intense follow-up with adapted treatment appears to be crucial to achieve cessation gradually in French smoking cessation services.
