A cohort study of 3358 power linesmen and 6703 power station operators classified in the 1960 population census in Sweden was undertaken. The cancer incidence between 1961 and 1979 was calculated in relation to all male blue collar workers. The relative risk of cancer (all sites) was 1.1, (1.0-1.2, 90% confidence limit) in the group of power linesmen and 1.0 (0.9-1.0) for power station operators. No consistent excess risk of leukaemia or brain tumour was found in the two occupational groups. In both groups a tendency towards an excess risk of cancer of the urinary organs was found.
对瑞典1960年人口普查中分类的3358名线路工人和6703名电站操作员进行了一项队列研究。计算了1961年至1979年间与所有男性蓝领工人相关的癌症发病率。线路工人组中所有部位癌症的相对风险为1.1(90%置信区间为1.0 - 1.2),电站操作员组为1.0(0.9 - 1.0)。在这两个职业组中未发现白血病或脑肿瘤的一致超额风险。在两组中均发现有泌尿系统癌症超额风险的趋势。
