BACKGROUND: Working in dusty environment face the risk of inhaling particulate materials that may lead to adverse respiratory effects. Sanitary workers are exposed to a number of pathogens, toxic substances, chemicals that come from the waste itself and from its decomposition. As a result of their exposure to multiple risk factors, they suffer high rates of occupational health problems, which would definitely alter the pulmonary functions and respiratory endurances. Individuals who breathe through their mouth have higher pulmonary ventilation rates when comparing to those who breathe through their nose. This is likely to be attributed to the occupational exposure of this group to workplace contaminants, particularly bio aerosols. So this study was done to evaluate the respiratory dysfunction among sanitary workers who are exposed to environmental and occupational hazards. AIM OF THE STUDY: To evaluate the occupational respiratory dysfunction among sanitary workers. OBJECTIVES: 1. To evaluate the respiratory functions in sanitary workers and normal healthy individuals. 2. To compare the effect of duration of exposure on respiratory functions in sanitary workers. MATERIALS AND METHODS: A cross sectional study was done after IEC approval, with written informed consent on 120 individuals of age group 20-45 years. Group I- 60 sanitary workers involved in waste collection and disposal of both gender. GROUP II- 60 healthy non exposed candidates, age and gender matched. Detailed history and clinical examination was carried out to rule out any acute or chronic illness. Information regarding respiratory illness, frequency and symptoms noted. The pulmonary function parameters; Forced Vital Capacity [FVC], Forced Expiratory Volume in 1 second [FEV1], Forced Expiratory Flow [FEF25–75] Peak Expiratory Flow [PEF] were recorded using spirometer, according to the American Thoracic Society criteria. Parameters were compared using SPSS16.0 version. RESULTS: All pulmonary function parameters were reduced in sanitary workers compared to control group. FVC%, FEV1 was reduced significantly. CONCLUSION: The lung functions are commonly affected due to occupational exposure in sanitary workers.
