Occupational lumbar back accidents in the private sector: prevalence and factors associated with their severity and sequelae in central Tunisia

In Tunisia, few studies have been focused on occupational lumbar back accidents. We conducted a descriptive retrospective study of private sector employees in central Tunisia who were victims of lumbar back accidents, reported during a 5-year period from 2010 to 2014, to determine the prevalence and factors associated with their severity and sequelae. Data were collected from the regional centre of the National Health Insurance Fund of Sousse. We identified 293 cases, a prevalence of 14.2% in relation to all occupational accidents reported during this period. More than two thirds of the injured (69.2%) were victims of serious occupational lumbar back accidents and 33.8% of victims reported serious sequelae. After adjustment by binary logistic regression, the occupational category persisted as an associated factor with the severity of occupational lumbar back accidents (P = 0.001, OR = 2.86 [1.50-5.47]). Surgical treatment appeared as an associated factor of severity (P < 0.001, OR = 9.06 [3.09-26.56]) and prominent after effects resulting from these accidents (P < 0.001 OR = 54.72 [18.84-158.93]). Occupational lumbar back accidents are a real health problem. Thus, a preventive strategy should be implemented to reduce their socio-economic consequences.
