The work ability index generally declines over time for Italian workers. Factors like job demands, control, and personal health significantly influence this trend, necessitating targeted interventions for aging workers.

Area of Science:

  • Occupational Health
  • Workplace Psychology
  • Ergonomics

Background:

  • Periodic health surveillance is crucial for monitoring worker well-being.
  • The Work Ability Index (WAI) serves as a valuable tool in assessing workforce health.
  • Understanding factors influencing WAI trends is essential for proactive health management.

Purpose of the Study:

  • To report the main results of studies on Italian workers using the WAI.
  • To analyze the trend of WAI over time in relation to working conditions and personal health.
  • To identify key factors affecting work ability and propose interventions for aging workers.

Main Methods:

  • Utilized the Work Ability Index (WAI) as a complementary tool for periodical health surveillance.
  • Conducted studies on a cohort of Italian workers.

  • Analyzed WAI trends based on job characteristics (mental involvement, autonomy, physical load, job control), sex, and working hours.

    • Main Results:

    • Observed a general decreasing trend in WAI over the years.
    • WAI remained high and constant in jobs with high mental involvement and autonomy, and low physical constraint.
    • WAI significantly decreased with higher physical workload and lower job control; sex and working hours interacted with job demands.

    Conclusions:

    • Work ability is influenced by a complex interplay of job characteristics and personal factors.
    • Jobs with high physical demands and low control show a steeper decline in work ability.
    • Flexible, targeted interventions addressing work organization and psycho-physical conditions are necessary to support aging shift workers and maintain work ability.
