Comparison of occupational interview data to death certificate data in utah

Abstract

Lifelong occupational histories obtained by interview prior to death were compared to death certificate data for 87 male bladder cancer patients in Utah. Agreement was defined as identical Bureau of Census codes, after predetermined groupings were made. Usual occupation, defined as that with the longest duration, agreed with the death certificate occupation for 54% of the individuals; usual industry agreed for 72%. Most recent occupation and industry agreed for 47% and 53%, respectively. For 69%, at least one interview occupation agreed with the death certificate occupation, and at least one industry agreed for 84%. Variables affecting agreement were duration of the job and education. Also examined were interview data about employment either during the last 15 years or prior to age 65 years, obtained from 112 male colon cancer patients. The Bureau of Census codes were in agreement for occupation in 63% and for industry in 65%. Duration of the job and education were related to percent agreement. We conclude that occupations and industries listed on death certificates reflect at least part of the work history of the majority of individuals.
