Rm. Semenciw et al., MULTIPLE-MYELOMA MORTALITY AND AGRICULTURAL PRACTICES IN THE PRAIRIE PROVINCES OF CANADA, Journal of occupational medicine, 35(6), 1993, pp. 557-561
A cohort study of agricultural practices and the mortality experience
(1971 to 1987) of male farmers in Manitoba, Saskatchewan, and Alberta
has been conducted. The census records of 156, 242 male farmers identi
fied on the 1971 Census of Agriculture and the corresponding Census of
Population were linked to mortality records through 1987. We observed
associations between multiple myeloma mortality and fuel/oil expendit
ures (relative risk for top quartile of exposure = 1.69, 95% confidenc
e interval = 1.08 to 2.65). No significant associations were found bet
ween multiple myeloma and herbicide use or with selected sociodemograp
hic variables.
