  1. Bias in risk estimates from variability of exposure to postural load on the back in occupational groups.

    Article - En anglais

    Variability of exposure can be a source of information bias in studies with exposure assessment based on the use of a sample of workers in each occupational group under study.

    This paper presents a method to assess the rate of exposure misclassification from the magnitude of overlap of exposure distributions and, consequently, to evaluate the bias to risk estimates in cross-sectional and prospective studies.

    The percentage of worktime with trunk flexion and rotation was studied in five occupational groups.

    The rate of misclassification of exposure to trunk flexion and rotation varied from 0.03 to 0.35.
