Article available from: www.scielo.br/rsp RSI/WRMSD in the third decade after restructuring of banking: new associated factors?ABSTRACT OBJECTIVE: To estimate the prevalence of cases suggestive of repetitive strain injury/work-related musculoskeletal disorders (RSI/WRMSD), three decades after restructuring of banking. METHODS:This was a cross-sectional study on 356 employees in 27 bank branches of public and private banks in Porto Alegre, Southern Brazil, between April and August 2009. After crude statistical analysis, adjustments were made using a Poisson regression model with robust variance and a threelevel hierarchy that incorporated the design structure and adjustments for the clusters. The results were stratifi ed according to the size of the bank branch and were dichotomized (> 25; ≤ 25 employees). RESULTS:The prevalence of cases suggestive of RSI/WRMSD was lower among the men (PR = 0.62; 95%CI: 0.47-0.81). Workers aged 26 to 45 years (PR = 2.51; 95%CI 1.02;6.14) presented greater prevalence of this outcome. Individuals with postgraduate qualifi cations (PR = 0.45; 95%CI 0.22;0.90) and length of time in the job between 5.1 and 15 years (PR = 0.62; 95%CI 0.47;0.81) presented protection against RSI/WRMSD. On stratifying the analyses according to size, it was found that age, income and length of time in the job remained associated in branches with 25 employees or fewer, while in branches with more than 25 employees, sex and schooling level were associated with the outcome. CONCLUSIONS:The characteristics of importance in relation to bank employees who become ill due to RSI/WRMSD seem to be different today from those that were known historically. Greater attention to organizing work and management strategies should be taken into consideration in drawing up illness prevention programs for banking work.
Objective: To evaluate muscular strain in the upper limbs of workers in a freeze-processing plant for poultry by developing a tool for quantitative analysis, yielding a final score, which can provide diagnostic support in legal proceedings. Methods: The Strain index proposed by Moore & Garg was used to quantify biomechanical aspects of muscular strain, evaluating the intensity and duration of effort, frequency of movement, position of wrist and hand, speed of activity and duration of the task per shift. The index was applied in three critical work-areas in a freezeprocessing plant for poultry where the activities of nine workers were analyzed. Results: Absenteeism caused by osteomuscular lesions and mental-health problems reaches 20%. The three work-areas studied are those where the birds' throats are cut, where they are suspended on a conveyor-belt and, where they are wrapped. These areas were chosen because they have the highest rates of absenteeism and rotation of workers. The findings identified final scores between 12 and 27, when 7 or more means the maximum risk. Conclusion: Defensive strategies developed by workers can reduce biomechanical problems arising from high throughput rates, but are not enough by themselves to allow production to proceed without the occurrence of osteomuscular problems.

Os dados foram coletados através de questionários estruturados. Para a análise da determinação das relações causais, utilizou-se a estatística analítica e inferencial e para a análise das cargas de trabalho e a forma como <span style="font-family: Helvetica; font-size: xx-small;">determinam o desgaste/ adoecimento, utilizou-se o Teste de Correlação de Pearson. </span></span></span><strong><span style="font-family: Helvetica,Bold; font-size: xx-small;"><strong><span style="font-family: Helvetica,Bold; font-size: xx-small;">Resultados: </span></strong></span></strong><span style="font-family: Helvetica; font-size: xx-small;"><span style="font-family: Helvetica; font-size: xx-small;">As situações problemáticas de trabalho que tiveram maior correlação com a sintomatologia osteomuscular e psíquica referida foram, respectivamente, a atividade estressante, volume de trabalho excessivo, exames médicos insatisfatórios, exigências posturais e cadeiras, equipamentos, máquinas desconfortáveis. As queixas dos fatores da organização do trabalho, psicossociais, do ambiente e do mobiliário são muito freqüentes, indicando a necessidade de modificações no ambiente de trabalho destes bancários. O sexo feminino prevaleceu (59,4% da amostra). A média de horas por dia de trabalho foi de aproximadamente 8 horas e 21 minutos. Houve forte correlação entre situações problemáticas de trabalho e problemas de saúde (88,46% foram significativas). Quanto ao acidente de trabalho, 61 (45,86%) referem que nunca sofreram acidente de trabalho, 38 (52,78%) sofreram doença do trabalho, 25 (34,72%) foram assaltados, 4 (5,55%) sofreram acidente típico, 2 (2.78%) sofreram acidente de trajeto, e 3 (4,17%) sofreram outro tipo de <span style="font-family: Helvetica; font-size: xx-small;">acidente. </span></span></span><strong><span style="font-family: Helvetica,Bold; font-size: xx-small;"><strong><span style="font-family: Helvetica,Bold; font-size: xx-small;">Conclusão</span></strong></span></strong><span style="font-family: Helvetica; font-size: xx-small;"><span style="font-family: Helvetica; font-size: xx-small;">: Identificou-se que os maiores comprometimentos na atividade de caixa de banco são em função do volume excessivo de trabalho, da exigência de esforço mental e principalmente as posturas inadequadas com a cabeça, mãos e braços. O estresse e as jornadas de trabalho, que costumam ser longas, favorecem o comprometimento do bem estar e a saúde do caixa, na busca, pelo mesmo, em conseguir atender a demanda de serviços existentes.</span></span>
