Thus the present study was undertaken to assess the health status of the residents and environmental conditions in the area in the vicinity of thermal power plant. Material and Methods: The present cross-sectional study included 408 residents in a 5 km radius around Padubidri thermal power plant. The information was gathered using interviewer administered semi structured questionnaire, measurement of peak expiratory flow rate using peak flow meter and environmental air monitoring using the Dust trak monitor. Results: It can be observed that majority of the subjects were in the age group ≥45years (50.7%) with the mean age of the participants being 43.08± 12.05 years. 82.8% were females and 17.2% were males.

Though the mean observed PEFR was lower in females, smokers, those residing very near to the plant, those with respiratory and allergic symptom. However, the difference was statistically non-significant (p>0.05). Conclusion: The present study highlights the presence of health problems particularly respiratory and allergic symptoms among the residents in the vicinity of thermal power plant.
