[Work ability and functional aging: a Systemic Analysis of the Literature using ProkNow-C (Knowledge Development...

Area of Science:

• Gerontology
• Occupational Health
• Sociology

Background:

• Brazil's elderly population is projected to reach 33.7% by 2060.
• Population aging impacts workforce capabilities and requires assessment.
• The Work Ability Index (WAI) is a key indicator for evaluating worker capacity.

Purpose of the Study:

• To conduct a bibliometric and systemic analysis of literature on work ability in aging populations.
• To identify key factors influencing the Work Ability Index (WAI).
• To assess the WAI as a diagnostic tool for functional aging in workers.

Main Methods:

• Bibliometric and systemic literature review using ProKnow-C.
• Analysis of 29 relevant papers.
• Survey methodology and cross-sectional study designs were prevalent.

Main Results:

• Work Ability Index (WAI) was consistently associated with sociodemographic data.
• Work ability generally decreased with increased age.
• Physical exercise positively correlated with higher WAI scores.
• Social life aspects significantly influence work ability.

Conclusions:

• The Work Ability Index (WAI) effectively diagnoses the working life situation of employees.
• Low WAI scores indicate potential early functional aging.
• Worker social life aspects are crucial determinants of work ability and should be assessed.
