ASSESSMENT OF PULMONARY FUNCTION TESTS AMONG RICE MILL WORKERS

Lung function tests have became an integral part of assessment of pulmonary disease of the respiratory system induced by occupational dusts are influenced by duration of exposure Occupational exposure to rice husk dust have been shown to affect functioning of different systems of the body. The present study was taken up to assess the Pulmonary Function Tests (FEV1/FVC) in rice mill workers. Methods: The present study was conducted in various Rice mills in and around Kurnool district with due permission of the owners from jan2019 to jan 2020 Fifty non-smoker males in the age group of 20?35 years working in rice mills for more than 1 year formed the study group. Age and sex matched individuals not exposed to rice husk dust served the control group. Pulmonary function parameters FEV1, FVC and FEV1/FVC were assessed using computerised Spirometer during their working hours and were statistically analysed. Results: There was a statistically significant decrease in FEV1, FVC and FEV1% in study group compared to control group with normal. Conclusion: Dust exposure in the working environment affects the lung function values and increased the respiratory symptoms among the rice mill workers.The above findings point towards adverse effects of rice husk dust on lung function, mainly on lower airways with obstructive pattern of disease.
