Resumen: El dolor lumbar tiene una larga asociación con diversas ocupaciones. En el marco de la salud laboral, este estudio tuvo como objetivo explorar la relación entre la discapacidad asociada al dolor lumbar y los riesgos físicos ocupacionales, las características sociodemográficas y la sensibilización central en hombres que trabajan en el sector industrial. Método: Realizamos un estudio analítico transversal en una empresa manufacturera. Las variables clave consideradas incluyeron la edad, la antigüedad laboral, los riesgos físicos ocupacionales, el Índice de Discapacidad de Oswestry (ODI) y el Inventario de Sensibilización Central (CSI). Resultados: Se seleccionó aleatoriamente a un total de 116 trabajadores manuales varones para participar en el estudio. Los riesgos físicos identificados fueron: posturas forzadas (84,50 %), manipulación manual de cargas (29,30%), movimientos repetitivos (16,40 %) y exposición a vibraciones (15,50 %). El ODI arrojó una puntuación media de9,91 (±12,47), mientras que el CSI obtuvo una media de 22,81 (±10,99). Se observó una relación positiva significativa entre la puntuación total del CSI y la puntuación total del ODI (p = 0,001). Posibles factores de confusión, como la edad, la antigüedad y el número total de riesgos laborales a los que estuvieron expuestos los participantes, no mostraron significación estadística. Conclusiones: Los hallazgos sugieren que, entre los hombres del sector industrial que presentan limitaciones funcionales relacionadas con el dolor lumbar, la sensibilización central puede ser un factor contribuyente. Se demostró que esta asociación era independiente de la edad, la antigüedad en el trabajo y el recuento acumulativo de riesgos físicos laborales a los que estaban expuestos los sujetos, teniendo en cuenta que los porcentajes de exposición a la mayoría de los riesgos físicos laborales estaban por debajo de los valores de referencia.
Introduction: Low back pain has long been associated with various occupations. In the context of occupational health, this study aimed to explore the relationship between disability associated with low back pain and occupational physical risks, sociodemographic characteristics, and central sensitization in men working in the industrial sector.
Method: We conducted a cross-sectional analytical study in a manufacturing company. The key variables considered included age, length of service, occupational physical risks, the Oswestry Disability Index (ODI), and the Central Sensitization Inventory (CSI).
Results: A total of 116 male manual workers were randomly selected to participate in the study. The physical risks identified were: forced postures (84.50%), manual handling of loads (29.30%), repetitive movements (16.40%), and exposure to vibrations (15.50%). The ODI yielded a mean score of 9.91 (±12.47), while the CSI yielded a mean score of 22.81 (±10.99). A significant positive relationship was observed between the total CSI score and the total ODI score (p = 0.001). Potential confounding factors, such as age, seniority, and the total number of occupational hazards to which participants were exposed, were not statistically significant.
Conclusions: The findings suggest that, among men in the industrial sector who have functional limitations related to low back pain, central sensitization may be a contributing factor. This association was shown to be independent of age, seniority, and the cumulative count of physical occupational hazards to which subjects were exposed, given that the percentages of exposure to most physical occupational hazards were below reference values.
