Background: Tobacco use is a public health concern worldwide as well as in India. The predominant use of tobacco is by smoke inhalation of cigarettes, pipes, and cigars or smokeless form. Smokeless tobacco is used in chewed, sniffed or sucked form. Tobacco smoking adversely affects the respiratory system causing chronic bronchitis, emphysema, chronic obstructive pulmonary disease, bronchial carcinoma. However the deleterious effects of smokeless tobacco on respiratory system are yet to be explored.
Aims & objectives: To study the adverse effects of smokeless tobacco on pulmonary function tests and compares them with smoked tobacco.
Methodology: The study was conducted among 30 tobacco nonusers or controls (Group I), 30 tobacco chewers (Group II) and 30 tobacco smokers (Group III). The pulmonary functions were conducted using the RMS Medspirometer. Pulmonary function parameters viz. FEV1, FVC, FEV1/FVC, FEF25-75%, PEFR and MVV were recorded and best of three readings were considered. Unpaired t test and ANOVA test were used for statistical analysis and statistical significance was set at p
spirometer, gastric esophageal reflux, antioxidants, restrictive, obstructive.
