    P3.06-014 - Onset of Silicosis among Sandstone Mine Workers in Rural Rajasthan, India (ID 1763)

    • Abstract

    Background:
    There are about 3 million workers at high potential risk of silica exposure in India and around 17 lakh in mining industry.[]But unofficialy figure for Rajasthan alone, over 2.5 million that are engaged in unorganized mine sector. The problem of silicosis is much more severe in the unorganized sector of industries like slate pencil cutting, stone cutting, and agate industry.The flaw here is because most industries belonging to the unorganized sector do not fall under the purview of Factories Act and Mines Act.
    
    Methods:
    Present study used the data from published report of detection of Silicosis by National Institute for Miner's health an autonomous Institute under Ministry of Mines, Government of India. ARAVALI a NGO based in Jaipur arranged for medical investigations (through Dang Vikas Sansthan (DVS), Karauli based voluntary organization, one of the ARAVALI‟s field host organization since 2008), of persons which had the history of work in stone mines. That included detailed work history, respiratory symptoms, history of treatment, chest radiography, sputum examination and pulmonary function test. The medical records evaluated by three specialists experienced in the evaluation of chest radiographs as per ILO classifications of radiographs for Pneumoconiosis, 2000. The report has published in three different time, first were in 2011 (101 miners),[] second 2014 (314 miners)[] and third 2014 (157 miners)[]. These reports cover stone miner from two districts of Rajasthan, named Karauli (first two reports) and Dhaulpur (third report). Reports include around 18 villages from Dhaulpur and 38 villages from Karauli. Thirty-four X-ray qualities were poor, and nine has no history of mining were not clinically evaluated for Silicosis. So, total 529 mine worker were clinically assessed for silicosis as per ILO classification of radiographs by the Institute. Cox regression is used for exploring the relationship between the onsets of silicosis among mine workers.
    
    Results:
    Bivariate analysis of the study shows that 58 % of the mine workers those diagnosed for silicosis were previously treated for TB. TB treatment, working duration in mines (16-30 years) and (30+ years) were found to be risk factors for Silicosis. The corresponding adjusted hazard ratios were 1.299(95 % C.I. 0.895, 1.886), 5.605(95% C.I. 3.485, 9.016) and 3.689(95% C.I. 2.73, 4.984). By age 40, maximum miners get silicosis found in life table analysis.
    
    Conclusion:
    Sandstone miners affected with silicosis but getting treatment of TB. After 15 years of work in mine, miners get affected with silicosis and by age 65 all miner get affected with silicosis if he continued to work.
