  Abstract

Abstract Objective. To model predictors of incident work-related musculo-skeletal disorders (WMSD). Methods. From four waves of the Canadian National Population Health Survey we constructed a cohort of working adults completing an abbreviated Job Content Questionnaire in 1994/5 and having no WMSD before 2000/01 (n=2806). Potential prior wave predictors of WMSD were modeled using multi-variable logistic regression. Results. Female gender (odds ratio of 1.98, 95% confidence interval, 1.24-3.18), some college or university education versus secondary or less (1.98, 1.06- 3.70), job insecurity (1.76, 1.07-2.91), high physical exertion (2.00, 1.29-3.12), and high psychological demands (1.61, 1.02-2.52) all positively predicted WMSD. Working less than 30 hours/week (0.2, 0.1-0.7) negatively predicted incident WMSD. Conclusion. Modifiable job characteristics are important predictors of incident WMSD.
