Predictors of the desire/decision to quit smoking in a cohort of Croatian adult smokers followed for five years: the crohort study.

This study provides an overview of the incidence of smoking, the socio-demographic characteristics of Croatian smokers during a five-year period and an assessment of predictors of the desire/decision to quit smoking. Analyses were performed separately for 2003 and 2008. A total of 3,229 subjects were included in the survey. There is a significant trend of a decreasing number of smokers in all age groups in 2008, compared to 2003. Almost half of the smokers included in the study expressed desire to quit smoking. Factors contributing significantly to decision to quit smoking were different in 2003 and 2008, except one. Concern about the harmful effects of tobacco smoking on health was a significant predictor in both models. Very worried respondents were more likely to decide to quit smoking (OR 17.6, 95% CI 9.41 to 33.17 vs. OR 12.54; 95% CI 6.0 to 26.2) than those who were not worried at all.
