Mortality and disability among cotton mill workers

Area of Science:

• Occupational Health
• Epidemiology
• Public Health

Background:

• Cotton mill workers face occupational hazards from raw cotton dust exposure.
• Previous studies suggest potential links between textile dust exposure and adverse health outcomes.

Purpose of the Study:

• To investigate the mortality and disability risks associated with long-term exposure to raw cotton dust in Finnish cotton mill workers.
• To compare the incidence of specific diseases and overall mortality in this cohort against national population data.

Main Methods:

• A cohort study of 1065 women hired between 1950-1971 in five Finnish cotton mills.
• Follow-up for disability pensions until 1981 and mortality until 1985.
• Analysis of prevalent and incident disability pensions for respiratory and musculoskeletal diseases, and standardized mortality ratios for various causes.

Main Results:

• Significantly higher prevalent and incident disability pensions for respiratory (p<0.01) and musculoskeletal diseases (p<0.01), including osteoarthritis and rheumatoid arthritis (p<0.05).
• No excess mortality from respiratory diseases; lower than expected cardiovascular disease mortality.
• Increased observed numbers of tumors in digestive organs (p<0.05) and deaths from renal disease (p<0.05).

Conclusions:

• Long-term occupational exposure to raw cotton dust is associated with increased disability from respiratory and musculoskeletal conditions.
• While overall mortality from respiratory diseases was not elevated, specific cancer and renal disease risks warrant further investigation.
• The findings highlight the importance of occupational health monitoring for textile industry workers.
