Information for Scientific Collaborators
Cancer incidence and mortality data on the cohort are being obtained from cancer registries within Iowa and North Carolina and state vital statistics offices on a yearly basis. In addition, mortality data on the cohort is being obtained every other year from the National Death Index (NDI). Cancer incidence in the cohort is presented in Table 2 and mortality in the cohort is presented in Tables 3.

1 Numbers represent medical conditions reported during Phase II interviews. Because the asking of some questions was dependent on responses to earlier questions, the counts in this table reflect the numbers of each condition reported but not the total occurrence of the diseases in the cohort.
2 These conditions marked with N/A were not asked about in the men's health questions. Since 96 percent of private applicators and commercial applicators in the cohort are men, it would be misleading to report counts for these conditions in the private applicator column.
3 Hearing problems were not asked about in the women's health questions. Since 99.5 percent of spouses in the cohort are women, it would be misleading to report hearing problem counts in the spouse column.
4 These conditions occur in commercial applicators in insufficient numbers to be reported at this time.
