Title Farming and prostate cancer mortality
Bibliographic information 1 Feb. 1993, Vol.137, No.3, p.270-280. Illus. 35 ref.
Abstract The study was based on a retrospectively assembled cohort of male Canadian farmers age 45 years or older for the period June 1971 to the end of 1987. The cohort was linked to the Canadian National Mortality Database. A total of 1,148 prostate cancer deaths and 2,213,478 person-years were observed. The study examined the relation between the risk of dying from prostate cancer and various farm practices. A weak, but statistically significant, association was found between number of acres sprayed with herbicides in 1970 and risk of prostate cancer mortality. When the analysis was restricted to farmers believed to be subject to the least amount of misclassification, the risk associated with acres sprayed with herbicides increased (rate ratio (RR)=2.23 for 250 or more acres sprayed; 95% confidence interval (CI) 1.30-3.84; test for trend, p<0.01). No other farm exposure examined was associated with any detectable pattern of increased or decreased risk.
