||An investigation of secondary exposure misclassification effects of lifelong occupational history in exposure estimation
||Mar.-Apr. 1999, Vol.60, No.2, p.175-181. Illus. 16 ref.
||In most studies, only the direct effects of misclassification of the interpretation of results of occupational epidemiological studies are considered, or - alternatively - simple estimates of misclassification rates are assigned to various types of exposure estimation processes. Lifelong job profile data obtained from a previously published case-control study provided job histories of 511 decedents. An analysis of these work histories and the comparison of exposures related to longest-held job to estimated total lifetime exposures suggest that single job-based exposure estimates may lead to significant exposure misclassification rates. In addition, the appearance of shorter duration jobs in a study population occurring predominantly early in the work history may exacerbate problems associated with exposure misclassification. The inclusion of extensive recording of the work history of study subjects emerges as a reasonable basis for the investigation and potential reduction of secondary misclassification of exposures in occupational epidemiological studies.
