ABSTRACT: Introduction: Low back pain is nowadays a real public health problem in companies. The objective of the study was to determine the prevalence and factors associated with chronic low back pain among workers of a mining company in Burkina Faso. Material and Methods: This was a descriptive and analytical cross-sectional study with a retrospective collection that took place from August 1, 2021 to March 16, 2022 in a gold mine in Burkina Faso. It focused on mine workers who participated in the 2019 annual medical visit. Results: Out of a total workforce of 880 workers who took part in the annual medical visit in 2019, 165 had chronic common low back pain, i.e. a prevalence of 18.75%. The average age of low back pain workers was 37.21 ± 7.5 years. Among the workers suffering from low back pain, 62 (37.58%) held the position of machine operator. Clinically, mechanical pain was found in 113 low back pain workers (76%) and twenty-nine (17.58%) had radicular pain. Standard radiography of the lumbar spine was abnormal in 129 workers (78.18%. In the univariate analysis, the factors associated with the pathology were sex, level of study, work station and seniority in the position. After a logistic regression, the factors associated with its occurrence were whole-body vibration (Fisher’s test = 12.7541; P = 0.000), male sex (Fisher’s test = 8.363; P = 0.004), and seniority for 4 to 5 years (Chi2 = 4.0234; p = 0.046). Conclusion: The study reveals the existence of chronic low back pain cases among the workers of the mining company. There is a predominance of the pathology in men, workers exposed to vibrations and those with a seniority of 4 to 5 years. It is necessary to establish a policy of prevention of low back pain for the benefit of workers, in particular those exposed to vibrations.
