Combinations of exposure to vibration, noise and ergonomic stressors in the swedish work force affect musculoskeletal health outcomes

Mats Hagberg, Andreas Jonsson

Abstract


The combinations of exposure to vibration, noise, and ergonomic stressors in the Swedish workforce, and the effect on self-reported health outcomes such as musculoskeletal symptoms and hearing problems, were studied. The definition of exposure to whole body vibration (WBV), hand transmitted vibration (HAV), and noise, were defined. Descriptive statistics were constructed for symptoms, vibration exposure, noise exposure, other risk factors, and age stratified for gender. In the sample of 12,546 persons representing the Swedish workforce, exposure to noise and ergonomic stressors such as lifting and bending is found to be frequent among both men and women, whereas vibration exposure, both HAV and WBV, is frequent among men but less than one percent among women. In a multivariate analysis, hand-arm vibration has a significant prevalence ratio of 1.5 for hand pain, even when controlling for whole body vibration, noise, frequent bending, lifting and twisted posture.
