The relationship between dyspnoea and main lifetime occupation in the elderly

Area of Science:

• Epidemiology
• Gerontology
• Occupational Health

Background:

• The PAQUID study is a prospective epidemiological research initiative focused on mental and functional aging.
• Previous occupational exposures may influence respiratory health in the elderly population.

Purpose of the Study:

• To investigate the association between lifetime main occupation and the presence of dyspnea in older adults.
• To identify specific occupational categories associated with an increased risk of dyspnea.

Main Methods:

• Analysis of baseline data from 3777 participants aged 65 years and older in the PAQUID cohort.
• Dyspnea was defined using the Fletcher classification (levels 3-5).
• Occupational categories were classified using French national statistics, with further detail for blue-collar roles.

Main Results:

• Dyspnea prevalence varied significantly across occupational categories, ranging from 13% in teachers to 37% in farm workers.
• Former farm workers, farm managers, domestic service employees, and blue-collar workers showed a significantly higher risk of dyspnea after adjusting for covariates.
• Odds ratios for dyspnea were elevated for former farm workers (OR=3.3), farm managers (OR=2.1), domestic service employees (OR=1.9), and blue-collar workers (OR=1.9).

Conclusions:

• Lifetime occupation has a significant long-term impact on respiratory health in the elderly.
• Specific occupations, particularly those involving manual labor and agricultural work, are associated with an increased risk of developing dyspnea later in life.
