A Comparative Study on Variations in Pulmonary Function Test in males of rice mill workers on their smoking habit
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2019, Vol 4, Issue 2
Abstract
Pulmonary diseases are on rise among smokers of rice mill workers. Pulmonary function test is a procedure to evaluate lung diseases. As per the WHO 51% of world populations are smokers and are prone to respiratory disorders. Industrial dust inhalation over a long period of time leads to pathological changes in the lungs of people exposed. Rice being major food for Indians, many people are employed in rice mills as daily wage labours. These individuals have more exposure to grain dust, this population is at risk especially smokers. Exposure to grain dust has a long history of association with diseases on various organs such as eyes, nose, skin, lung and the airways. The current study is designed to know the variations in the values of the forced vital capacity (FVC), peak expiratory flow rate (PEFR), forced expiratory volume in the first second (FEV1), and FEV1/FVC percentage among smokers and non-smokers of rice mill workers. A cross-sectional study was conducted at Osmania Medical College, Hyderabad from 1996 to 1998 were the sample size considered was 100. Mixed population of male and female was enrolled for the study to avoid bias in current study 78 male smokers with age of 20 to 40 years were considered for studies. Smokers with previous history of lung disease were excluded from the studies. P value<0.05 considered as statistically significant and confidence interval (CI) was 95%.Total of 78 male workers participated in the study, the average values of FVC in smokers was 1.70±0.42 when compared to non smokers 2.80±0.26 L (t-13.98), accordingly FEV1 was 1.19±0.31L in smokers and 2.49±0.21 in non smokers (t-9.71), FEF25-75% (L/S) was 1.41±0.28 in smokers and 2.89±0.47 in non smokers. The FEV1: FVC ratio 69.83±8.91% in smokers and in nonsmokers were 87.92±7.87, PEFR 3.43±0.21L in smokers and 5.38±0.26 in non smokers. The recorded FVC was found to be significantly reduced in smokers of rice mill workers. The mean FVC, FEV1 and PEFR were lower in smokers. Health awareness and educational campaigns are needed to keep the society to avoid smoking and to reduce respiratory diseases especially among the rice mill workers.
