Queixas osteomusculares dos trabalhadores e condições biomecânicas no trabalho em metalúrgica de alumínio

Abstract

Background: Aluminum is a metal commonly found in bauxite ore and Brazil is a major producer worldwide. Studies describe work-related musculoskeletal disorders among workers in the aluminum industry. Objectives: Evaluating ergonomic conditions and musculoskeletal complaints among workers in an aluminum smelter. Methods: Cross-sectional study carried out in an aluminum smelter in Embu das Artes, São Paulo. Checklists were applied to simplify evaluation of the risk of lower back pain and the risk of musculoskeletal disorders of the upper limbs related to work in a specific sector. The 38-sector workers answered to the Nordic Musculoskeletal Questionnaire (NMQ). Results: The ergonomic conditions present moderate risk for lower back pain and upper limb disorders. In the last 12 months, 15.8% of workers complained of back pain and in the last seven days, 5.3% of workers reported complaints of pain in wrists/hands/fingers. Conclusion: Biomechanical conditions of work can be related to musculoskeletal complaints. The management of occupational hazards in this branch of industry is needed to promote productivity and quality of life among workers.
