Dor musculoesquelética relacionada ao trabalho e sua associação com transtornos mentais comuns em trabalhadores de um frigorífico do Sul do Brasil / Work-related musculoskeletal pain and its association with common mental disorders among employees of a poultry producing company in Southern Brazil

Contexto: A dor musculoesquelética é um dos problemas ocupacionais mais comuns nas sociedades industrializadas, e sua prevalência é potencialmente associada à presença de transtornos mentais. Objetivo: Estimar a prevalência de dor musculoesquelética relacionada ao trabalho e sua associação com a presença de transtornos mentais comuns em trabalhadores de um frigorífico do Sul do Brasil. Métodos: Realizou-se um estudo transversal com o total de 1.103 trabalhadores, de 18 a 52 anos de idade, em 2010. A dor musculoesquelética foi avaliada por meio de uma figura humana adaptada do Questionário Nórdico de Sintomas Osteomusculares. Considerou-se o relato da presença de dor relacionada ao trabalho em qualquer região do corpo nos últimos 12 meses. A presença de transtornos mentais comuns foi determinada pelo Self-Reporting Questionnaire (SRQ-20). Razões de prevalências (RP) brutas e ajustadas, com seus respectivos intervalos de confiança de 95% (IC95%), foram obtidas mediante a regressão de Poisson. Resultados: A prevalência de dor musculoesquelética relacionada ao trabalho foi de 40,3% (IC95% 37,4­43,2) na amostra geral, 46,8% (IC95% 43,2­50,5) nas mulheres e 27,8% (IC95% 23,2­32,3) nos homens. Na análise bruta, trabalhadores com presença de transtornos mentais comuns apresentaram prevalência duas vezes maior de dor musculoesquelética relacionada ao trabalho quando comparados com aqueles sem transtornos (RP=2,27; IC95% 1,99­2,58). Esse efeito manteve-se significativo após o ajuste para variáveis sociodemográficas, comportamentais, de saúde e ocupacionais. Conclusão: Os resultados deste estudo alertam para a importância de medidas visando à promoção da saúde física e mental dos trabalhadores em ações para reduzir a dor

Background: Musculoskeletal pain is one of the most common occupational problems in the industrial society and its prevalence is potentially associated with mental disorders. Objective: To estimate the prevalence of work-related musculoskeletal pain and its association with occurrence of common mental disorders among employees of a poultry processing company in Southern Brazil. Methods: Cross-sectional study conducted in 2010 with 1,103 employees aged 18 to 52 years old. Musculoskeletal pain was investigated based on a human figure adapted from the Standardized Nordic Questionnaire. We considered reported work-related pain in any part of the body in the past 12 months. Occurrence of common mental disorders was assessed by the Self-Reporting Questionnaire (SRQ-20). Crude and adjusted prevalence ratios (PR) and corresponding 95% confidence interval (95%CI) were obtained by Poisson regression with robust variance. Results: The prevalence of work-related musculoskeletal pain was 40.3% (95%CI 37.4­43.2) for the total sample, 46.8% (95%CI 43.2­50.5) for women and 27.8% (95%CI 23.2­32.3) for men. The prevalence of musculoskeletal pain was twice higher for the participants with common mental disorders compared to those without this condition (PR=2.27; 95%CI 1.99­2.58). This effect remained significant after adjustment for sociodemographic, behavioral, health-related and occupational variables. Conclusion: The results of the present study point to the relevance of preventive measures to promote the mental and physical health of workers in order to reduce or minimize the occurrence of pain

Job characteristics and musculoskeletal pain among shift workers of a poultry processing plant in Southern Brazil.

OBJECTIVES: The purpose of this study was to evaluate the association between job characteristics and musculoskeletal pain among shift workers employed at a 24-hour poultry processing plant in Southern Brazil. METHODS: This was a cross-sectional study of 1,103 production line workers aged 18-52 years. The job characteristics of interest were shift (day/night), shift duration, and plant sector ambient temperature. Musculoskeletal pain was defined as self-reported occupational-related pain in the upper or lower extremities and trunk, occurring often or always, during the last 12 months. RESULTS: The mean (SD) participant age was 30.8 (8.5) years, and 65.7% of participants were women. The prevalence of musculoskeletal pain was greater among female participants than male participants. After adjustment for job characteristics and potential confounders, the prevalence ratios (PR) of lower extremity musculoskeletal pain among female workers employed in extreme-temperature conditions those working the night shift, and those who had been working longer on the same shift were 1.75 (95% CI 1.12, 2.71), 1.69 (95% CI 1.05, 2.70), and 1.64 (95% CI 1.03, 2.62), respectively. In male workers, only extreme-temperature conditions showed a significant association with lower extremity musculoskeletal pain (PR=2.17; 95% CI 1.12, 4.22) after adjustment analysis. CONCLUSIONS: These findings suggest a need for implementation of measures to mitigate the damage caused by nighttime work and by working under extreme temperature conditions, especially among female shift workers, such as changing positions frequently during work and implementation of rest breaks and a workplace exercise program, so as to improve worker quality of life.
