ABSTRACT
Employers need a clear understanding of the risk factors associated with low back (LB) injury for future prevention in the workplace. A data mining approach was used to analyse data-sets (Workers' Compensation claims data for employees participating in a health and wellness programme at a Midwestern university) in a retrospective study to summarise the risk factors associated with LB injury. Eight risk factors (age, cause of injury, night shift, fatigue, emotional health, stress level, physical and emotional impairment) are associated with LB injury in the workplace. Age was an effect modifier: lifting, twisting, bending (LTB) and emotional risk factors were associated for employees younger than 40 years old, whereas LTB, slips, trips, falls, and physical risk factors for employees 40 and older. Future considerations discussed not only engineering solutions, but the psychological and lifestyle risk factors associated with LB injury and the need for development of preventative programmes.
