Work Ability and Occupational Health Factors

Work ability refers to the extent to which an individual is physically, mentally and socially capable of meeting the demands of their occupation. It emerges from the dynamic interplay between personal resources—such as health status, functional capacity and motivation—and workplace factors, including job demands, organisational support and the work environment. Occupational health factors encompass a broad spectrum of influences on workers’ capacity to remain productive and well, ranging from ergonomic conditions and psychosocial stressors to organisational culture and health promotion initiatives. Research in this field addresses how ageing workforces, technological change and evolving employment models shape work ability trajectories, with a view to preventing long-term absence, disability pension and early retirement. Robust measurement tools and interdisciplinary interventions are central to monitoring trends, identifying at-risk groups and designing targeted strategies that enhance both individual well-being and organisational performance.

Research from Nature Portfolio

Recent qualitative inquiry has deepened understanding of how teachers perceive their own work ability within the framework of occupational stress. Using the Job Demands-Resources model, researchers explored how excessive workload, emotional labour and work–family conflict undermine teachers’ physical and mental health, leading to fatigue and reduced perceived capacity. The study highlighted that inadequate recognition of the holistic nature of work ability can delay interventions and exacerbate health impairment. Findings call for integrated approaches that address both organisational policies and individual coping mechanisms to sustain teaching effectiveness.

Technical terms

Work Ability Index (WAI): A questionnaire-based tool assessing an individual’s capacity to meet work demands, encompassing health status, mental resources and job requirements.

Perceived Work Ability: A self-assessment of one’s capability to perform work tasks effectively, reflecting personal judgment of physical, mental and social functioning.

Job Demands-Resources (JD-R) model: A theoretical framework positing that job demands (e.g. workload, emotional strain) and job resources (e.g. support, autonomy) jointly influence employee health, motivation and performance.

Biological age: An estimate of physiological ageing based on biomarkers such as telomere length or DNA methylation patterns, which may diverge from chronological age in reflecting health risk.
