<u>Impact Of Occupational Hazards And Individual Characteristics In Underground Coal Miners Injuries: Matched Analysis In A Case-Control Study.: </u> This Case-Control Study Assessed The Relationships Of Job-Related/Environmental-Related Hazards And Individual Characteristics Of The Workers With Occupational Injury In Underground Coal Mines. It Compared 245 Cases With At Least One Injury During The Previous Two-Year Period With 245 Matched Controls With No Injury. The Data Were Gathered Via Personal Interview And Analyzed Via The Conditional Logistic Model And The Cox Proportional Hazard Model. In This Study Statistically Significant Risk Factors Were Identified And Their Roles Were Assessed In Shift Work Operation. The Conditional Logistic Regression Analysis Revealed That Significant Risk Factors Are Risk Taking Behavior (Adjusted Or 10.49), Big Family Size (5.88), Handling Materialrelated Hazards (5.57), Less Experience (3.16), No Formal Education (2.86), Presence Of Diseases (2.63), Environment/Working Conditions-Related Hazards (2.50), Geological/Strata Control-Related Hazards (2.34), And Regular Consumption Of Alcohol (2.29). Environment/Working Conditionrelated Hazards And Geological/Strata Control-Related Hazards Are Associated With High Risks Of Injury Among The Face Workers Only. But These Hazards Are Non Significant In Case Of Non-Face Workers. Machine-Related Hazards Affected More Of The Subjects Aged < 45 Years While Environment/Working Condition-Related Hazards And Smoking Affected More The Subjects Aged ≥ 45 Years. Smoking Habit And Environment/Working Condition-Related Hazards Are Found Significant In Fall Types Of Injury While No-Formal Education, Regular Alcohol Consumption, And Electric Equipment-Related Hazards Are Found Significant In Other Types Of Injury. The Cox Regression Analysis Revealed That The Significant Risk Factors In Shift Work Are Regular Alcohol Consumption, Risk-Taking Behaviour, Environment/Working Condition-Related Hazards And Geological/Strata Control-Related Hazards. The Workers Who Were Regularly Consuming Alcohol In Shift Work Are 1.47 Times More Likely To Risk Of Injury Compared To General Shift Work. Preventive Measures Should Be Implemented To Reduce Environmental Hazards And Geological/Strata Control-Related Hazards At The Workplaces And Various Safe Lifting Procedures Should Be Developed By The Mine Management Regarding The Different Operations Of The Handling Of Materials. Interventions Involving Occupational Physicians, Safety Officers, And Mine Managers To Prevent Work-Related Diseases And To Improve Health Status And Health-Related Behaviors (Smoking And Alcohol) Are Needed To Reduce Occupational Injuries.
