• Description:
  Job exposure matrices are becoming more and more widely used, including use for estimation of biomechanical exposures. In the context of providing exposure data available for international research, an international team created an employment exposure matrix from the first available data from the Constances cohort, called "JEM Constances." As part of ongoing efforts to compare different JEMs, we compared similar exposure variables from JEM Constances to those assigned in a JEM used for public health purposes in the same country, the French "MADE" ("Matrice Associant Difficultés physiques au travail et Emploi," French for "difficult physical conditions and job matrix"). We studied the correlation and the agreement of exposure estimates for different job titles between these two matrices. Briefly, the Constances cohort created a JEM based on self-reported exposures to 27 different biomechanical factors at the level of the job, using the French "professions et catégories socioprofessionnelles (PCS) 2003" national job codes. The MADE matrix coded 17 different exposures using consensus estimates from occupational health experts, using the same PCS codes. The relevant variables were crossed to obtain Spearman correlation coefficients for JEM Constances and MADE, using the PCS 2003 code as a unit and using the subject by applying the two matrices on available data on Constances cohort. Three categories for variables of both JEM Constances and MADE were also obtained based on the tertiles of the distribution using Constances cohort. Thus, a calculation of a Kappa agreement was also performed with similar units. The results on the selected variables are fairly good (Table 1) except for exposures to the neck and to work in cold environment (less than 10 degrees C), where some coefficients were lower than 0.5.
