Objective:
To study the incidence rates and the determinants of smoking cessation in a population-based cohort.
Material And Methods:
We used data from the Cornellà Health Interview Survey Follow-up Study. Subjects who declared they were daily smokers at baseline (1994) and had complete follow-up, with information on smoking status in 2002, entered into analysis. We calculated incidence rates and the relative risks of cessation (with 95% confidence intervals) using the Cox model.
Results:
Out of 353 daily smokers, 100 quit smoking during the follow-up period (cumulative incidence of 28.3%). The incidence rate of cessation was higher among men (42.34 per 1000 person-years) than among women (24.97 per 1000 person-years), with a relative risk of cessation of 1.69 (95% confidence interval, 1.02-2.79) for men. Age and level of education were associated with a higher relative risk of quitting in men.
Conclusions:
The main determinants for smoking cessation are sociodemographic (sex, age, and level of education).
