Resumen
The objective of this study was to quantify and assess whether lifting tasks in the workplace are a risk factor in lumbar spondyloarthrosis etiology. A case-control study was performed with 231 workers, 18 - 55 years old, insured by the Mexican Social Security Institute (IMSS, according to its designation in Spanish). A multivariate analysis using conditional logistical regression showed that lifting tasks, combined with driving tasks, are associated with this illness (OR = 7.3; 95% CI 1.7 - 31.4). The daily frequency of lifting as it interacts with work as a driver resulted in a greater risk (OR = 10.4; 95% CI 2.0 - 52.5). The load weight, daily task-hours and cumulative time showed a dose-response relationship. The attributable risk for lifting tasks was 0.83, suggesting that 83% of lumbar spondyloarthrosis development could be prevented if risk factors were eliminated by ergonomic redesign of the task. © 2005 IOS Press.
