Abstract

This study assessed the associations of some occupational and individual factors with injuries among the employed people of an underground coal mine situated in the southern part of India. This work was conducted on 164 coal miners. Out of the 164 coal miners 82 miners faced at least one injury during a two-year period (injured group) and the remaining 82 miners did not face any injury in their career (non-injured group). The injured and non-injured groups were matched on age and job. A questionnaire was filled in by the personnel interviews. It included birth-date/age, height, weight, family size, educational level, smoking habit, alcohol consumption, overtime work, experience, presence of disease and occupational injuries during the two-year period. Statistical analysis was made using the STATA (Stata Statistical Software) package. To assess the relationships of each factor to the injuries, the McNemar's Chi-Square values for the matched data (1:1 matching) were computed. The McNemar's Chi-Square values for the significant factors were: presence of disease (Chi-Square =11.11, P less than or equal 0.001), overtime work (f=14.30, P gt 0.001), educational level (Chi-Sq=5.54, P greater than 0.05) and alcohol consumption (Chi-Sq=12.52, P less than or equal 0.001). The crude odds ratio of each factor with injury was calculated by the McNemar's 1:1 matched data analysis. The factors with significant odds ratios were the presence of disease (OR 3.50, 95% CI 1.55-8.88), alcohol consumption (OR 3.18, 95%CI 1.57-6.94), overtime work (OR 4.28, 95%CI 1.889.75) and no-formal-education (OR 2.71, 95%CI 1.09-7.64).
