Abstract: | The lumbar region is located in the lower part of the spine, allows twisting, and bending, provides strength to stand, walk and lift objects. (1). The present study makes it possible to use statistical analyzes to identify the risk factors associated with lumbar pathologies, diagnosed on radiographs. The data are taken from the medical records of 668 Ecuadorian employed patients. The statistical methodology includes a univariate and bivariate exploratory analysis, the application of probabilistic models to detect variables significantly associated with the pathologies, and the evaluation of the best predictive model. The best results are evidenced with the Logit model, with a sensitivity = 84%, specificity = 77%, area under the ROC curve = 0.81 and precision = 79%, with an optimal cut = 0.48. The profile of patients who have the most frequent pathology (low back pain) and in order of importance are: thenpresence of pain, younger age, female sex, they tend to be exposed to psychosocial risk factors at work, lower BMI, and lower risk of having mechanical factors. While the profile of patients who have the less frequent pathologies (myelopathy, radiculopathy, other disorders of the invertebral disc) are: no presence of pain, older age, male sex, lower risk of having psychosocial factors, higher BMI and tend to be exposed mechanical risk factors. |
