We appreciate the opportunity to respond to comments by Valentgas and colleagues regarding our report examining mortality among rubber chemical manufacturing workers [Prince et al., 2000]. Following are our responses to their comments, focusing on the authors' main points: The article should emphasize results of county mortality rate comparisons. Standard epidemiologic methods for comparing rates of mortality in occupational cohorts were used in this study. The analyses using U.S. referent rates are important in view of the fact that the ``healthy worker effect'' (HWE) for ischemic heart disease (IHD) has often been observed in occupational cohort analyses using U.S. referent rates [Sterling and Weinkam, 1986]. Since there is no ideal referent population in this study, data from local (county) and U.S. rates were presented in conjunction with the internal plant comparison and limitations of each approach were discussed in detail.
