Title Dose-response relations between occupational exposures to physical and psychosocial factors and the risk of low back pain
Bibliographic information Dec. 2004, Vol.61, No.12, p.972-979. 33 ref.
Abstract To assess dose-response relations between occupational exposures to physical and psychosocial factors and the risk of low back pain, a cohort of 523 subjects, working in nursing homes and homes for the elderly, was followed for one year. Physical load for different occupations was assessed by quantitative observations at the workplace. Information on low back pain and other factors was gathered with questionnaires administered at baseline and at one year. Two outcome measures of low back pain incidence were used: any new episode of pain lasting for at least a few hours during follow up (LBP); and any new episode of disabling pain that interfered with daily activities during follow up (LBP/D). Results indicate that the risk of LBP was not associated with physical factors, but this outcome was inversely associated with age and weakly, though imprecisely, associated with two psychosocial factors (low decision authority and high work demands). In contrast, the risk of LBP/D was positively associated with age and not associated with the psychosocial factors. Occupational exposure to trunk flexion over 45 degrees appears to be a risk factor for low back pain with disability.
