Background Estimating a person's history of occupational exposure in case‐control studies is difficult. Methods Percent agreement between selected self‐reported occupational exposures and job‐exposure matrix (JEM) exposure assessment for all participants and various subgroups of a population‐based case‐control interview study of 486 leukemia subjects and 502 healthy controls in Shanghai was evaluated. Results With JEM as the “gold standard,” the sensitivities for self‐reported exposures ranged from 0.75 to 0.98. However, that for pesticide exposure was 0.44 in subjects >51 years old. Self‐reported exposures specificities ranged from 0.87 to 0.99. Agreement between self‐reported exposures and JEM assessment was good (kappa coefficients [κ]: 0.48–0.84). Variations in agreement for benzene exposure between males and females as well as between the direct interview and surrogate interview subgroups were observed. Conclusions The levels of agreement between self‐report and JEM in this study suggest that self‐reported exposures are a suitable method for assessing occupational exposures in this population. Am.
