A study was carried out among 5734 persons having incident cancers to assess the utility of using the latest occupational information as a summary of occupational histories. Complete lifetime occupational histories were obtained by telephone interviews for black and white males and females between the ages of 40 and 84 years. Usual industry and occupation were determined by summing the total number of months during which a person was employed in a specific industry or occupation over the entire work history. It was found that 73.6 percent of the records were identical for usual and latest occupation and that 76.6 percent matched for usual and latest industry. White males showed the highest matching percentages of 78.9 and 82.2 percent for occupation and industry, respectively. Matches for occupation and industry were lowest for blacks, females, and persons 40 to 49 years old. Over 90 percent of the records with at least 20 years in latest employment were matches. The authors suggest that due to variations in match rates depending on race and sex, there is a need to evaluate more fully the agreement of latest and usual employment patterns when interpreting the results of large scale occupational surveillance studies.
