Índice de riesgo para desarrollar trastornos musculoesqueléticos por levantamiento manual de carga en trabajadores de la empresa “Ejeproy CIA. LTDA”. Cuenca, septiembre 2022 – febrero 2023

Abstract

Background: Estimated risk level of suffering from some Occupational Musculoskeletal Disorders (MSD) is crucial in current studies. Construction is one of the sectors most affected by the handling of loads due to the need to mobilize materials, equipment, and products required for each job. Objective: Determine the risk index for developing musculoskeletal disorders by manually lifting loads in workers of the "Ejeproy CIA. LTDA" company. Methods: A quantitative study of analytical scope, cross-sectional and observational, was performed with a sample of 25 workers. The NIOSH equation was applied to assess the risk of suffering MSD. Data obtained were analyzed with SPSS 20.0. The chi-square statistic (X2) was needed to evaluate the statistical relationship between the variables collected and the risk of MSD. It was considered statistically significant for values of p <0.05. Results: Young adults predominated, with 58.3%, all of whom were male. The years of experience vary, and they work an 8-hour working day. The lifting index had an average value of 2.50 ± 0.99. It was verified that 91.7% of the workers were not in the allowed categories, showing a moderate or considerable risk. Conclusions: Most workers are at moderate or significant risk of musculoskeletal disorders, especially older and more experienced workers.
