Smoking is a serious public health problem. The campaign against tobacco is largely supported by health professionals, especially doctors. The physician is a model for the community and therefore should give the example avoiding smoking. Objectives: This work seeks to evaluate the magnitude and the distribution of smoking habit among physicians in Rio Grande, state of Rio Grande do Sul, southern Brazil, and characterize the smoking doctor's profile. Method: Data were obtained, in 1999, through application and analysis of a questionnaire, based on the model proposed by WHO, among 333 physicians of whom 213 (64%) were men and 120 (36%) were women. The average age of the sample was 43 (± 10.5) years with 65.1% between 30 and 50 years. Results: Smoking prevalence was 18.3% (15.9% regular smokers and 2.4% occasional smokers). Regular smoking prevalence was 17.8% among males and 12.5% among females, with no significant statistic difference (p > 0.05). The mean number of cigarettes smoked was 24.3 packets/years, being superior among men and increasing with age. It was verified that 86.8% of the smokers began smoking before 20 years of age, due to their desire or friends' influence in 63.2% of the cases. Conclusion: Although smoking prevalence among Rio Grande physicians is lower than in other countries, it is still unacceptable. Since this class has a decisive role in the prevention and fight against smoking, a specific campaign against tobacco among these professionals would greatly justify.

Introduction: The University Hospital is reference in the city of Rio Grande, in the State of Rio Grande do Sul, Southeast part of Brazil, for chronic lung disease patients, with a major smoking cessation program. Aim: The purpose of this work was to analyze the utilization of Fagerström Tolerance Questionnaire to assess the nicotine dependence of smoking patients with reference to individualization of treatment. Material and Method: The authors used the Fagerström Tolerance Questionnaire (FTQ) in daily smoking adult patients from the Medical Clinic and Chest Medicine Units of the University Hospital and Rio Grande Santa Casa Hospital, during the period of one year. Three hundred and one valid questionnaires were filled out, 40.5% by females and 59.5% by males. Mean age was 48.6 years. The score of the questionnaires classified patients by dependence into five degrees: very low, low, medium, high, and very high. Results: 54.9% belong to the group of high nicotine dependence (score ³ 6), with a significant correlation of elevated nicotine dependence and cigarettes per day or time to the first cigarette of the day (p < 0.001). Conclusion: The use of the FTQ demonstrated ease of administration and more than 50% of the patients with a degree of chemical dependence that anticipate discomfort at cessation of smoking and need of treatment to control the withdrawal symptoms.
