Factors predicting the initiation of a tobacco cessation program in Spain.

There have been limited studies regarding the characteristics of subjects who have decided to initiate a cessation program to quit tobacco smoking. Identifying such characteristics is important because it provides information regarding recruiting and tailoring strategies, as well as intervention methods. This observational trial with cross-sectional data analysis sought to identify the characteristics of subjects who have decided to initiate a smoking cessation program compared with those who did not. All subjects who asked for information about our cessation program between January 2000 and December 2005 were eligible for participation. All subjects were interviewed regarding their tobacco consumption practices. We also collected information on medical history and psychological conditions. Multivariate analysis was used to identify variables associated with the decision to initiate the cessation program. A total of 1,681 subjects asked for information about smoking cessation at our center, and 1,132 (67.3%) decided to enter our program. Independent factors associated with the decision to initiate the cessation program included female gender (OR: 1.54; 95% CI:1.23-1.93), having a university degree (OR: 1.46; 95% CI: 1.12-1.88), bronchial asthma (OR: 0.41; 95% CI: 0.24-0.71), nonpsychotic psychiatric disorders (OR: 0.52; 95% CI: 0.40-0.66), psychotic disorders (OR: 6.00; 95% CI: 2.74-13.14), and a history of insomnia (OR: 6.22; 95% CI: 1.85-20.87). Although all smokers should be counseled to quit smoking, our data may help to concentrate efforts on some subjects in order to increase the participation in smoking cessation programs.
