Abstract : To study respiratory diseases in children staying in a stone quarry. Prospective longitudinal study. All 85 children staying in the stone quarry near Pune were followed for respiratory symptoms and nutritional status by monthly visits for a period of 18 months. At the time of enrolment, Hemogram, CXR (PA), TT test, PEFR (Of children age: 5-12 yrs.) was done. In 85 children followed, there were 394 episodes of respiratory infections (3.09 episodes per child per year). They had 53 episodes of pneumonia requiring admission. TT test was positive in 9.4%of children. Eosinophilia was present in 16.47% of children. PEFR in these children was significantly lower than that of children of the same height (p< 0.05). 64.2% of all children were malnourished. 42.8% had moderate malnutrition and 21.4% had severe malnutrition. None of them had received even vaccines provided under EPI completely. Children staying in the stone quarry have frequent respiratory infections. They have a higher rate of pneumonia requiring admission. TT positivity is high. They have a lower PEFR. Immunization coverage is poor.
