Background: Whole-body-vibrations are often associated with adverse health effect but the long term effects are less known. This study investigates the association between occupational exposures to whole-body vibrations, and
subsequent transition to disability pension.
Methods: A total of 4215 male employees were followed up for subsequent disability pension retirement. Exposure to whole-body-vibration was self-reported while new cases of disability pension were retrieved from a national register.
Results: The hazard ratio (HR) for disability pension retirement among men exposed to whole-body-vibrations was 1.61 (95% confidence interval (CI) 1.07-2.40) after adjustment for age, smoking habits, BMI, physical job demands and awkward work postures. In our model, with the available explanatory variables, 5.6% of the male disability pension
cases were attributable to whole-body-vibrations.
Conclusions: Exposure to whole-body-vibrations predicts subsequent disability pension retirement. Continued
reduction of whole-body-vibrations may reduce the number of new cases of disability pension.
