SOUZA, Norma Suely Souto and SANTANA, Vilma Sousa. Cumulative annual incidence of disabling work-related musculoskeletal disorders in an urban area of Brazil. Cad. Saúde Pública [online]. 2011, vol.27, n.11, pp.2124-2134. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2011001100006.
This study focused on the annual cumulative incidence (ACI) of disabling work-related musculoskeletal disorders affecting the neck and/or upper limbs (ULMSD) among workers covered by the National Social Insurance System in the city of Salvador, Bahia State, Brazil. Cases were workers who received disability compensation benefits when unable to work due to ULMSD, during the year 2008. The data were obtained from the administrative systems of the National Social Insurance Institute and Ministry of Labor and Employment. ACI was 15 per 10,000 workers. Increased ACI of ULMSD was associated with female gender, lower income, and work in financial activities or manufacturing. Women earning the minimum wage (US$ 64.00 per month) or less had the highest ACI of ULMSD (123 per 10,000), suggesting inequalities in the occurrence of these disorders. The study indicates the need to prioritize preventive actions focusing on ergonomics and work organization, early diagnosis, treatment, and rehabilitation.
