In a response to a letter to the editor by R. Y. Demers et al (see NIOSHTIC record NIOSH-00241135) on their article entitled Colon and Stomach Cancer Mortality among Automotive Wood Model Makers (Journal of Occupational Medicine, Vol. 34, pages 759-768; see NIOSHTIC record NIOSH-00209392), the authors presented additional information and discussed some of their design elements. They stressed that 79% of the cohort had at least 5 years of employment in a studied facility. They addressed the possibility of changing exposures by including separate tests for associations between mortality from colon and stomach cancer and wood model making exposures after 1955. No association was found. In response to the concern that wood dust may have been a poor choice as the potential carcinogen, the authors noted that they also analyzed the duration of time employed in wood model making because other potential carcinogens in addition to wood dust may have been present. They noted that about 90% of the jobs with wood dust as their predominant exposure also exposed workers to plastics and solvents. They also tested for associations between mortality and the duration employed in this field. All the odds ratios they calculated either for wood dust or for the cumulative duration employed in wood model making were less than 1.0 and nonsignificant.
