Abstract
In an earlier study, we identified 26 diseases of possible occupational origin, seen in different settings within the national health system in Catalonia. In this literature review we identify those occupational risk factors most strongly associated with these pathologies. After applying inclusion/exclusion criteria to 754 reviews, meta-analyses and/or practice guidelines, 37 articles remained that were rated for study quality by 3 reviewers. Of these, the 31 studies of highest quality were examined in depth, and summarised in a final table. Ergonomic risk factors (manual handling of materials, highly repetitive movements and awkward postures), especially for musculoskeletal disorders of the upper extremity, and exposures to chemical products and physical agents, were prominent. These results provide an additional resource for primary care physicians to assist them with the identification of possible occupational illness and to improve communication between the National Health Service and social security system.
