Area of Science:

  • Occupational Health
  • Sociology
  • Ergonomics

Background:

  • The Work Ability Index (WAI) is a validated tool, but reference data for Chinese workers are lacking.
  • Understanding work ability across demographics and job types is crucial for occupational health.
  • Existing WAI data often lacks specificity for diverse populations like those in western China.

Purpose of the Study:

  • To establish comprehensive WAI reference data for workers in western China.
  • To analyze WAI variations based on gender, age, and work content.
  • To provide a benchmark for future occupational health studies and interventions in China.

Main Methods:

  • A large-scale random sample of 10,218 workers from western China was analyzed.
  • Participants represented diverse occupations including manual, professional, and clerical roles.

  • The validated Work Ability Index (WAI) questionnaire was administered to all participants aged 16-69.

    • Main Results:

    • Work Ability Index (WAI) scores showed a near-normal distribution, declining with age.
    • Female workers exhibited significantly higher WAI scores than male workers.
    • WAI scores varied significantly by work content and age group, with manual laborers showing earlier declines.

    Conclusions:

    • The Work Ability Index (WAI) is validated for use in Chinese occupational settings.
    • This study provides essential gender, age, and work-content-specific WAI reference values for China.
    • The generated data will facilitate comparative analyses and intervention evaluations in occupational health research.
