Abstract

Background and objectives: The majority of individuals in a population do not develop tuberculosis, due either to lack of exposure or due to individual characteristics that limit development of the disease after exposure. Evidences suggested that there is an association between lifestyle variables and tuberculosis. The main objective of this study was to study the association between lifestyle characteristics and pulmonary tuberculosis. Methods: A case-control study was carried out in Erbil city during the period May 10, to December 28, 2009. A convenient sample of 150 cases of TB attending the Consultation Clinic for Chest and Respiratory Diseases was included in the study. A sex and age matched, 150 patients were included in the study as a control group. The control group was taken from patient of the Medical Wards of both Rizgary and Hawler Teaching Hospitals who were free from chest infections and lung cancer. Cases and controls were interviewed using a questionnaire designed by the researchers. Results: Around one quarter (24%) of the cases were smokers compared with 14.7 % among the controls. Significant difference of nutritional status between both groups was detected. Controls eat more food and of better quality than cases. No significant association between alcohol drinking, practicing of sports/ exercise and TB was detected. Conclusion: TB was found to be associated with low nutritional status and smoking.
