Objectives: The aim of this study was to determine the associations between demographics, work, lifestyle, housework, and the work ability of workers.
Methods: Employees between the ages of 20 and 69 (N = 651), employed at a Brazilian public institution, responded to a questionnaire on demographics, work, lifestyle characteristics, and work ability.
Results: Work ability decreased significantly with age among the women. The younger group had higher scores on the work ability index than the older age groups, except for mental resources. The logistic regression analysis showed that higher age, lower education, and long work history at the institution were significantly associated with reduced work ability.
Conclusions: The progressive aging, the low level of education, and the long duration work in the studied institution were related to a reduction in work ability, which increases the risk of work disability or early retirement.
