Comparative study of Ventilatory Functions of Cotton Mill Workers, Mumbai, India
Abstract
Background & objectives: The present observational study was carried out in cotton mill workers of Mumbai to compare the pulmonary functions with those of apparently healthy population and to find out the effect of duration of exposure to the working environment.
Materials & Methods: The study group comprised of 150 cotton mill workers and 150 workers of hospital staff, all males, in age group of 25-60 years. Socio-demographic characteristics and occupational history was noted in predesigned questionnaire performa for both groups. Respiratory functions namely FEV1, FVC, FEV1/FVC & PEFR were recorded by using portable and electronic instrument pneumotachometer, results were analysed by using difference of means.
Results: The pulmonary functions were found to be significantly lower in cotton mill workers as compared to hospital staff and pulmonary functions were correlated negatively with duration of exposure to the cotton dust.
Conclusion: In spite of modernization and recent technical evolution the working conditions and occupational environment has still a long way to go as per as the safety of cotton mill workers of Mumbai city is concerned.
