Age specific standardised mortality ratios (ASMRs) were compared for commercial fishermen under 55 years old and those who were aged 55 and older in the Canadian Atlantic coastal provinces of Nova Scotia, New Brunswick, and Prince Edward Island. The subjects were a cohort of 31,415 fishermen licensed by the Department of Fisheries and Oceans during 1975-83. Mortality was obtained by a computerised linking of the registry of licensed commercial fisheries and the Canadian Mortality Data Base. Fishermen under 55 had ASMRs between 1.4 and 1.7 for death from all causes and around 1.0 for death from non-accidental causes. The older fishermen had ASMRs as low as 0.6 for all causes and non-accidental causes. The same pattern was shown for death from specific causes such as ischaemic heart disease, accidents, and cancer, as well as for different years of entry into the cohort. This pattern differed widely from that of most other occupations. Dividing the cohort into owners and crew members showed that the high mortality ratios at younger ages existed in crew members only. It was concluded that the high death rates for fishermen under 55 had a socioeconomic component.
对加拿大新斯科舍省、新不伦瑞克省和爱德华王子岛这几个大西洋沿岸省份中55岁以下和55岁及以上的商业渔民的年龄标准化死亡率（ASMRs）进行了比较。研究对象是1975年至1983年期间由渔业和海洋部颁发执照的31415名渔民组成的队列。死亡率通过将商业渔业执照登记册与加拿大死亡率数据库进行计算机链接获得。55岁以下渔民的全因死亡率的年龄标准化死亡率在1.4至1.7之间，非意外原因导致的死亡的年龄标准化死亡率约为1.0。年龄较大的渔民全因和非意外原因导致的死亡的年龄标准化死亡率低至0.6。对于特定原因导致的死亡，如缺血性心脏病、事故和癌症，以及该队列不同年份进入的情况，也呈现出相同的模式。这种模式与大多数其他职业的模式有很大差异。将该队列分为船主和船员后发现，仅船员中存在年轻年龄段的高死亡率。研究得出结论，55岁以下渔民的高死亡率有社会经济因素。
