Abstract: Background: To investigate the intersection of aging with work
limitations, chronic medical and musculoskeletal conditions, and physical
functioning we undertook a cross-sectional study of U.S. construction roofers
who were current union members between the ages of 40 and 59. Methods: Participants were asked about the presence of medical
conditions and musculoskeletal disorders (MSDs); the Work Limitations
Questionnaire, the SF-12, and other validated assessments of social and
economic impact of injury were included. Results: Sixty-nine percent had at least one of these
conditions in the previous two years; 31% missed work. Workers with medical
and musculoskeletal conditions were older, had the highest prevalence of work
activity limitations, and had the lowest SF-12 scores. Conclusions: Older age was associated with the presence of a
medical condition, and with reduced physical functioning. Medical and
musculoskeletal conditions were strongly associated with work limitation,
missed work, and reduced physical functioning. Older workers may be at higher
risk of disability retirement compared to younger workers with similar medical
conditions and work limitations.
