A mortality study of about 326,000 Canadian male farm operators enumerated in the 1971 Census of Agriculture is being conducted by Health and Welfare Canada in collaboration with Statistics Canada. The study examines the mortality patterns of farm operators in relation to farm practices and a variety of socio-demographic variables. The prime concern is the association between pesticide use and certain cancers suggested in previous studies of farmers. This article describes the methodology used to create the study cohort and the analysis files. Highlights of the preliminary results from this study for Saskatchewan are also presented. Results for other regions are forthcoming. Among the Saskatchewan cohort of farm operators, 94% of deaths occurred within the province. The average age at death was 67.9 years and the average length of survival from 1971 was 13.9 years. Although the cohort as a whole had no excess mortality for any specific cause of death--including non-Hodgkin's lymphoma--significant dose-response relationships were noted between risk of non-Hodgkin's lymphoma and acres sprayed with herbicides in 1970, as well as with dollars spent in 1970 on fuel and oil for farm purposes (1).
加拿大卫生福利部与加拿大统计局合作，对1971年农业普查中登记的约32.6万名加拿大男性农场经营者进行了一项死亡率研究。该研究考察了农场经营者的死亡率模式与农场作业以及各种社会人口统计学变量之间的关系。主要关注点是先前对农民的研究中所表明的农药使用与某些癌症之间的关联。本文描述了用于创建研究队列和分析文件的方法。还介绍了该研究针对萨斯喀彻温省的初步结果要点。其他地区的结果即将公布。在萨斯喀彻温省的农场经营者队列中，94%的死亡发生在该省内。平均死亡年龄为67.9岁，从1971年起的平均存活时长为13.9年。尽管该队列总体上没有因任何特定死因（包括非霍奇金淋巴瘤）出现超额死亡率，但在非霍奇金淋巴瘤风险与1970年喷洒除草剂的英亩数以及1970年用于农场目的的燃料和机油支出之间，发现了显著的剂量反应关系(1)。
