    Pulmonary function indices like FEV1% and MMEF are key indicators for assessing the work ability of aging workers. This study highlights their importance over FVC and FEV1 for objective evaluation.

    Area of Science:

    • Occupational health
    • Pulmonary medicine
    • Gerontology

    Context:

    • Aging workforce demographics present unique occupational health challenges.
    • Work ability is crucial for sustained employment and productivity in older workers.
    • Understanding the link between physiological function and work capacity is vital for workplace interventions.

    Purpose:

    • To investigate the correlation between specific pulmonary function indices and work ability in aging workers.
    • To determine which pulmonary function measures best predict or align with overall work ability.
    • To identify objective biomarkers for evaluating the work capacity of individuals aged 40-60.

    Summary:

    • A study of 285 aging workers (40-60 years) in Chengdu assessed pulmonary function (FVC, FEV1, FEV1%, MMEF, PFI) and Work Ability Index (WAI).

  • Significant differences in FVC and FEV1% were observed across work types, and FVC differed between sexes.
  • Pulmonary Function Index (PFI), particularly FEV1% and MMEF, showed a significant relationship with WAI, suggesting their utility in work ability assessment.

    • Impact:

    • FEV1% and MMEF show promise as objective measures for evaluating the work ability of aging workers.
    • Findings can inform targeted health surveillance and support programs for older employees.
    • This research contributes to a better understanding of physiological determinants of work capacity in later working life.
