Effect of smoking on peak expiratory flow rate in Tikrit University


This is a cross sectional study designed to evaluate the effect of smoking on pulmonary function test using Peak Expiratory Flow Rate measurement. It was conducted in Tikrit University during the period from the 1st of November to the 30 of December 2010 on 103 healthy smokers and nonsmokers, both students and university employees whose age range was (23-60) years. Peak Expiratory Flow Rate was measured , the results were expressed as Mean and Standard Deviation. The results showed that 70 subjects(68%) of the total are smokers smoking. The number and percentage of passive smokers was 21 subjects (64%) of those who does not smoke. Those who smoke <10 cigarettes per day was 16 subjects (23%), 20 cigarettes per day was 30 subjects(43%), those who smoke>20 cigarettes per day were 24 subjects(34%) of the total. There was a statistically significant difference in the Mean and Slandered Deviation in Peak Expiratory Flow Rate between smokers and non smokers, also the same difference was found between those who are exposed to passive smoking and those who are not exposed from those who were non smokers
