Association of leukemia with agricultural occupation.
National Institute for Occupational Safety and Health, Cincinnati, Ohio, Final Report 1978 Jan; :1-4
NIOSH funded studies were conducted to reexamine the relationship between leukemia and agricultural occupation. Focus was on reexamination of findings of Milham (1971), who found a strong relationship between the raising and marketing of poultry and the occurrence of leukemia and multiple myeloma. Data were obtained from 5385 questionnaires returned by survivors of persons dying from hemopoietic neoplasms, 2637 questionnaires relating to death from pancreatic carcinoma (control), and 9834 questionnaires concerning control deaths matched by age, sex, race, and county of residence. Data were taken from 1972 to 1975 from the states of Illinois, Indiana, and Wisconsin. Hemopoietic neoplasms included lymphomas, leukemia, lymphocytic leukemia, multiple myeloma, and myelocytic leukemia. Odds ratios of contracting hempoietic neoplasms were found to increase as the intensity of lifetime exposure to agriculture increased. The strongest effect was found for 45 year old (and older) male residents who had no other occupation other than farming. Odds were highest for contracting lymphocytic leukemia. Male and female differential indicated that farm occupational exposure rather than farm residence alone contributed to the increased odds ratios. No demonstrable association between poultry farming and hemopoietic neoplasms was found. It is concluded that there is a significant association between selected hemopoietic neoplasms and farm residence/agricultural occupation.
