Smoking is well-known to cause respiratory disorders and pulmonary functions decline. In India, where majority of the population lives by agriculture and linked occupations in rural areas despite of rapid increase in urban population, the pulmonary function is expected to vary between rural and urban areas. Rural and urban variations in disease distribution are well known. Respiratory system evaluation and screening can easily be done by Pulmonary Function Tests. This study was carried out in the Kosi region of Katihar, Bihar, in 100 participants. For this study, computerized spirometer (RMS Helios 701) was used. In view of increasing behaviour of smoking among the rural and urban population of Kosi region of Bihar, this study was undertaken, for a better understanding of the correlation between smoking and its effects on pulmonary functions. It was observed that pulmonary function in mean ± standard deviation in urban smokers, FVC was 2.54 ± 0.86 litres, FEV1 1.81 ± 0.88 litres, FEV1 % was 74.83 ± 31.43 and PEFR was 5.98 ± 2.35 litres and FEF25-75% was 2.95 ± 1.31 litres. The pulmonary function tests in rural smoker population in mean ± standard deviation, FVC was 2.56 ± 0.86 litres, FEV1 2.21 ± 0.96 litres, FEV1 % was 86.00 ± 23.73 and PEFR was 5.65 ± 2.18 litres and FEF 25-75% was 3.34 ± 1.37 litres. The comparison of PFT in urban smokers and rural smoker population was significant with “p” value <0.05 only in FEV1, other parameters showed insignificant results.
