COMPARISON OF THE EFFECTS OF VARIOUS MODES OF SMOKING ON THE PULMONARY FUNCTIONS IN HEALTHY VOLUNTEERS

摘要

Objectives: Smoking is common in our society and day by day number of smokers are increasing. Smoking causes serious health hazards such as respiratory diseases, lung, and oral cancers. Methods: This cross-sectional study involved 60 smokers of age 18-45 years and 60 age-matched non-smokers who were otherwise healthy as controls. The smokers were subgrouped into cigarettes smokers (n=30) and beedi smokers (n=30). Pulmonary function parameters such as forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV percentage (FEV1/FVC), peak expiratory flow rate (PEFR), forced expiratory flow (25-75%) and maximum voluntary ventilation were measured for all the participants using computerized spirometer. Results: All the above pulmonary function parameters were significantly reduced (p<0.05) in smokers when compared to non-smokers. When compared with cigarette smokers, beedi smokers have a more significant reduction in pulmonary function. Conclusion: Smokers have reduced lung functions when compared to non-smokers. Beedi smokers were more affected when compared to cigarette smokers and obstructive pulmonary impairment was the most common.
