Objectives: This study aimed to examine the influences of cigarette smoking on pulmonary functions among solder smokers. Subjects and methods: 160 military personnel who came for health checking in Central Military Hospital 108 from May 2013 to April 2014 were recruited in the study. Among them, one hundred were current smokers and the rest (n = 60) were non-smokers. Pulmonary Function Tests were conducted by Spirometer Chestgraph H1-101 (Japan). Results: The parameters of pulmonary functions among smokers were SVC (3.32 ::!: 0.54 L), FVC (3.65 +/- 0.47L), FEV! (2.41 +/- 0.55L), FEV1 percent (75.13 +/- 5.72 percent), FEV/FVC (66.0 +/- 0.67 percent) and PEF (6.27 +/- 0.87 Up), FEF 25-75 percent (7.25 +/- 0.46; 3.27 : +/- 0.52 and 1.16 +/- 0.26 L). All values were significantly lower than those in non-smokers (p 0.05). The prevalence of PFT disorders was 72 percent and 9.9 percent in the group of smokers and non-smokers, consecutively. Conclusion: Tobacco smoking significantly decreases SVC, FVC, FEV1, FEV10/0, FEV1/FVC, PEF, FFF 25-75 percent and increases a rate of PFT disorders.
