Analysis of Laboral and Non-laboral Risk Factors of Workers Diagnosed with Lumbar Pathologies. Study of Cases

An analysis is presented of occupational and non-occupational risk factors of four workers diagnosed with lumbar pathologies in a pet food manufacturing company. Through a survey, individual aspects were investigated, exposure to risk factors present in the working conditions of the task, the environment and organization, as well as extra-labor factors according to scientific literature. Occupational antecedents were found by carrying out load handling activities and exposure to factors of the three dimensions described. Regarding the extra-labor component, they have carried out activities similar to those outside the working day. The above is corroborated according to literature given that structures of the lumbar spine can be subjected to excessive compression and shear forces plus the presence of muscle fatigue, amplified by job characteristics, organizational and extra-labor aspects. It is required to determine criticality levels of these factors and more studies in this regard.
