Exposure Assessment Using Job Exposure Matrices

Job exposure matrices (JEMs) are an efficient way to assign exposure estimates in population-based studies and may be the only exposure assessment option when only job and industry are available for study participants. DCEG investigators develop methods to improve JEMs by incorporating databases of exposure measurements to calibrate JEMs across time and across jobs and industries. For example, in the Shanghai Women's Health Study, investigators developed a novel framework to systematically combine a JEM with historical measurements to calibrate JEM exposure ratings used to estimate historical benzene and lead exposure (Ann Occup Hyg 2012).
