Abstract

AIMS: The present study was designed to investigate the simultaneous effects of physical, psychosocial and other work-related risk factors on the work ability index (WAI) score among industrial workers.

METHODS: This study used a cross-sectional design with a questionnaire survey. 280 workers were included in the study. Data were collected using three questionnaires including the Persian version of WAI (P-WAI), the Persian version of job content questionnaire (P-JCQ) and an author-developed measure (to assess work-related factors, health-related factors and socio-demographic characteristics).

RESULTS: The majority of the participants were young, however, they had poor WAI scores (with mean of 37.3 ± 6.4) and 44.3% of them had poor or moderate work ability. Occupational accidents and injuries were found to be the strongest predictors of WAI scores. Additionally, there was a strong association between WAI scores and supervisor support, skill discretion, occupational training, sleep quality, work nature and educational level.

CONCLUSIONS: Intervention programs should focus on improving supervisor support, sleep quality, job skills and knowledge and decreasing physical and mental work demands. Additionally, implementing a comprehensive occupational health and ergonomics program for controlling and reducing hazardous working environments and occupational injury rates should be considered.
