[Probability of success in tobacco quitting during the course of two simple medical interventions].

Introduction And Objectives: Counselling for tobacco quitting could be improved by informing smokers about the likelihood of success in quitting over time since the start of an intervention for smoking cessation. This study assessed the change in the probability of success in tobacco quitting during the course of two simple medical interventions for smoking cessation.

Methods: Prospective study in three worksites in the Basque Country (Spain), which underwent two interventions for quitting.

Subjective health of male ex-smokers: relationship with time since smoking cessation, intensity and duration of tobacco consumption.

Background: To examine the relationship of subjective health with time since smoking cessation and amount and duration of tobacco consumption among male ex-smokers.

Methods: Pooled analysis of three household interview surveys conducted in 1993 (n = 8,494), 1995 (n = 2,556), and 1997 (n = 2,624) on samples representative of the noninstitutionalized population aged 16 and over in Spain.

Results: After controlling for the main confounders, ex-smokers with smoking burden < or =13 pack-years had a lower frequency of suboptimal health (fair, poor, or very poor) than current smokers (OR, 0.

Changes in the prevalence of overweight and obesity and their risk factors in Spain, 1987-1997.

Background: The aim of this study was to examine the relationship of the changes in the prevalence of overweight and obesity with the changes in some of their risk factors in Spain from 1987 to 1997.

Methods: Data were obtained from three interview-based health surveys, covering representative samples of the noninstitutionalized Spanish population aged 16 years and over and undertaken in 1987 (n = 17,434), 1995 (n = 4,736), and 1997 (n = 4,678). To compensate for the different sample sizes, the 1995 and 1997 surveys were combined.
