          Abstract

          OBJETIVO: Validar a versão brasileira do Nordic Musculoskeletal Questionnaire -- NMQ (Questionário Nórdico de Sintomas Osteomusculares -- QNSO) e apresentar as relações entre morbidade osteomuscular e variáveis demográficas, ocupacionais e relativas a hábitos. MÉTODOS: A versão brasileira do instrumento NMQ foi aplicada a uma amostra de 90 empregados em uma instituição bancária estatal, em Brasília, em 1999. Foram realizadas análises descritivas da amostra e de associação entre as variáveis. Os resultados foram comparados a dados relativos à história clínica de cada respondente. Realizou-se análise estatística de comparação entre grupos (Test t) e de correlação entre variáveis (Pearson). RESULTADOS: Os resultados mostraram concordância entre o relato de sintomas no NMQ e a história clínica em 86% dos casos. Foram verificadas diferenças na prevalência de sintomas quanto ao gênero, à função exercida e à prática de atividade física. As mulheres apresentaram maior média de severidade de sintomas em quase todas as regiões anatômicas; os gerentes relataram maior severidade de sintomas em região lombar do que escriturários; a prática de atividade física regular esteve associada à menor severidade de sintomas em membros superiores. CONCLUSÕES: Os resultados mostram um bom índice de validade concorrente para a versão brasileira do NMQ e recomendam sua utilização como medida de morbidade osteomuscular. Entretanto, o instrumento necessita de uma medida de severidade de sintomas e de alterações na diagramação e no conteúdo da escala para torná-la mais compreensível e menos suscetível a um excessivo número de respostas em branco.

          OBJECTIVES: To validate the Portuguese version of the Nordic Musculoskeletal Questionnaire (NMQ), and to evaluate the relationship between musculoskeletal morbidity and demographic, occupational and behavior variables. METHODS: Ninety government bank employees were interviewed using the Portuguese version of NMQ in Brasilia, Brazil, in 1999. The respondents' answers were compared to clinical data found in their medical records. Descriptive and associative variable analyses were carried out. Comparative statistical analysis was performed using Student t-test and Pearson's test was applied for correlational analysis. RESULTS: The results revealed an 86% agreement rate between symptoms reported in the NMQ and the respondent's clinical history. There were found differences in symptoms prevalence for the variables gender, occupation and physical activity. Women showed a higher severity average of symptoms for almost all body anatomical regions; managers reported greater severity of symptoms in the lumbar area than clerks; physical activity was associated to the lowest severity of symptoms in upper extremities. CONCLUSIONS: The results show that the Portuguese NMQ version includes a good validity indicator and is satisfactory as a musculoskeletal morbidity measurement tool. However, there is a need of (1) more items to measure the severity of symptoms; and (2) changes in scale layout in order to make it more easily understandable and less prone to avoidable missing data.

          Questionnaire development: an examination of the Nordic Musculoskeletal questionnaire.

          This paper describes the outcome of user trials of the Nordic Musculoskeletal Questionnaire which encompassed the views of the following groups: data entry clerks, technical staff, administrative clerks and 481 subjects employed in 10 supermarkets. A significant number of improvements was identified, especially concerning its wording, layout and administration. This has led to a standardized version being produced for use in studying the prevalence of reported symptoms in many types of occupational groups.

            Job task and psychosocial risk factors for work-related musculoskeletal disorders among newspaper employees.

            A cross-sectional study was conducted to assess the association of upper extremity musculoskeletal disorders and work-related factors among employees using video display terminals at a large metropolitan newspaper. The study included 1050 randomly selected workers from four departments. The workers were asked to complete questionnaires on symptoms, job tasks, and psychosocial and work organization conditions. Musculoskeletal disorders of the upper extremities were defined by frequency, duration, and intensity of symptoms not attributable to acute injury. Data were analyzed with the use of logistic regression. A total of 973 workers completed the survey. The one-year period prevalence rate for any musculoskeletal disorder of the upper extremities was 41%. Neck symptoms (26%) were the most frequently reported, followed by hand or wrist (22%), shoulder (17%), and elbow (10%) symptoms. Greater time working at the video display station was associated with increased hand or wrist symptoms in a dose-response relationship. In addition, variables corresponding to increased work-load demands (eg, increased time working under deadline and increased job pressure) were associated with increased neck, shoulder, and hand or wrist disorders. Women were more likely to report symptoms in several areas, but this finding may reflect the concentration of women in jobs involving more risk factors. The results suggest a high prevalence of musculoskeletal disorders of the upper extremities among newspaper employees, and they provide additional evidence that increased work load, time pressure, and greater hours of computer use are related to the occurrence of work-related musculoskeletal disorders among these workers, particularly for disorders in the hand or wrist area.

              Psychosocial stressors at work and musculoskeletal problems.

              This paper examines the relationship between work stressors and the following health indicators: psychosomatic complaints, health behavior, and musculoskeletal problems. Secondary analyses were performed on data from the National Work and Living Condition Survey, which provides a representative sample of the working population in The Netherlands. The survey was made in 1977, 1983, and 1986 by The Netherlands Central Bureau of Statistics. By means of factor analysis the following three risk dimensions were identified in the survey: work pace, intellectual discretion, and physical stressors. High work pace, low intellectual discretion, and physical stressors were associated with increased health complaints (both psychosomatic and musculoskeletal) and musculoskeletal disorders after adjustment for gender, age, education, and sports participation. Low intellectual discretion, but not high work pace, was associated with poor general health and health behavior indicative of poor health. Physical stressors were associated with general health as well, but not with health behavior, except for reported absenteeism. Psychosocial stressors are not only associated with psychosomatic complaints and health indicators, but also with musculoskeletal problems, both acute and chronic. Especially the relation between intellectual discretion and musculoskeletal problems can be partly attributed to physical load. Even after adjustment for physical stressors and moderating personal characteristics, the relationships between the psychosocial stressors and musculoskeletal problems remained significant and comparable in strength to the relationship between psychosocial stressors and several other health outcomes, such as psychosomatic complaints.
