Summary
Appalachian coal miners face elevated heart disease risks, particularly obese smokers. Working miners had lower standard mortality ratios (SMRs) than nonworking miners, but job roles impacted risk.
Area of Science:
- Occupational Health
- Cardiovascular Epidemiology
- Environmental Health
Background:
- Heart disease poses a significant public health challenge.
- Coal mining communities, like those in Appalachia, may experience unique occupational health risks.
- Understanding risk factors within specific occupational groups is crucial for targeted interventions.
Purpose of the Study:
- To determine the standard mortality ratio (SMR) for heart disease in Appalachian coal miners.
- To investigate the influence of smoking, excess weight, and physical activity on heart disease mortality.
- To examine SMR variations across different underground work categories.
Main Methods:
- A cohort study of 3,726 Appalachian coal miners.
- Calculation of SMRs for all heart disease and ischemic heart disease.
- Analysis of risk factors including smoking, obesity, and physical activity levels.
- Comparison of SMRs between working and nonworking miners and across job roles.
Main Results:
- Overall SMR for heart disease was 73 for working miners and 104 for nonworking miners.
- Obese smokers exhibited the highest risk, with SMRs of 142 (working) and 144 (nonworking).
- Maintenance workers showed the highest SMR among nonsupervisory underground roles, while face workers had the lowest.
Conclusions:
- Appalachian coal miners, especially nonworking individuals, face increased heart disease mortality.
- Obesity and smoking are significant risk factors for heart disease in this population.
- Occupational roles within mining influence heart disease risk, highlighting the need for tailored health programs.
