Modeling determinants of working exposures and exposure variability Trask, Catherine; Koehoorn, Mieke; Village, Judy; Teschke, Kay; Johnson, Peter W.


Work-related back injuries represent 25% of workplace injuries in British Columbia, and more than a quarter of all back strain claims are from employees in five high-risk industries: forestry, wood and paper products, construction, transportation, and warehousing. Epidemiological studies require data on physical exposures to risk factors from large numbers of individuals in order to observe exposure-response relationships and for the results to be representative and generalizable. Unfortunately, there is a tradeoff between precision and expense, with the most precise measurement methods being too expensive to use in large epidemiological studies. The overall goal of this study is to identify a suite of measurements that afford both precision and cost efficiency for large scale work-site studies of numerous physical exposures across diverse settings and occupations.
