Lung Cancer Epidemiology in New Mexico Uranium Miners. Second Annual Report, April 1-December 15, 1984

摘要

For the retrospective cohort study of miners with first underground experience before 1971, abstracting and entering of the majority of the Grants Clinic smoking and mining histories has been completed, and editing is under way. All company-reported Working Level Months (WLM) data for 1967-1982 have been abstracted, keyed, and edited. For earlier years, the data base of working level measurements obtained from state agencies is also completed. Further follow-up of the cohort has been accomplished through the Social Security Administration and the National Death Index. Death certificates have been requested for 75 deceased cohort members. For feasibility evaluation of a prospective cohort study of miners with first underground experience after 1970, refinements of previous projections of available subjects have been made. An estimated 10,447 persons are available but with low mean cumulative exposures. Grants Clinic information for these miners has not yet been collected. Finally, planning for analysis has continued. To calculate comparison mortality rates, it is necessary to derive population estimates for New Mexico from 1957 through 1982. Counts have been developed for 1970 through 1982, and much of background work on the earlier years has been done. Alternative statistical approaches for data analysis are also being considered. 4 tables. (ERA citation 10:009095)
