SURVEY OF PULMONARY FUNCTION TESTS IN MALE TOBACCO ADDICTS EXAMINED AT HUE UNIVERSITY HOSPITAL

Abstract

Background: Cigarette smoking is known as a menace and contagious problem. The World health organization reported that tobacco smoking killed 6 million people worldwide in 2011 and warned that it could kill one billion people around the world in 21st century also. Tobacco smoking is the leading known risk factor for the development of lung cancer, stroke, and chronic obstructive pulmonary disease (COPD). Smoking is the primary cause of airway obstruction, chronic expectoration and decline in lung function. Spirometry is the best method to detect borderline to mild airway obstruction, which occurs early without appearance of any symptoms or signs. The aim of this study was to evaluate the pulmonary function parameters and ventilatory disorders in men smokers. Material and Methods: This was a comparative cross-sectional study. There are 180 male subjects, 90 smokers (age 39.1±8.1, height 163.5±6.9) and 90 non-smokers (age 39.0±9.4, height 164±5.6) were included using convenience sampling. The pulmonary function test was measured by HI-801 spirometer. The following variables were measured: FVC, FEV1, FEF25-75%, PEF. Results: The results showed that most value measured in smokers were significantly lower than those of non-smokers (p<0.05). The prevalence of small airway obstructive disorder was 37.8%, obstructive disorder was 27.8%, restrictive disorder was 1.1%, mixed disorder was 18.9%. Conclusions: In tobacco addicts, smoking confers a high risk factor of developing the deteriotation of the ventilatory function.
