A study of deaths from Nasopharyngeal Carcinoma (NPC) among males in Hong Kong from the years 1976 to 1981 was conducted. Variations in NPC mortality among different occupational groups were investigated. The average death rate from NPC among males was 14 per 100,000 in the past ten years which is among the highest in the world. Comparisons using age specific mortality rates and direct age standardized mortality rates between occupational groups revealed increasingly high mortality in agricultural and fishery occupations (p less than 0.01), and being lowest among administrative occupations (p less than 0.05). The ten highest proportional mortality ratios for occupations were calculated and showed significantly high ratios among fishermen, plumbers, welders and fitters. The paper reviewed and discussed the possible reasons for these findings.
对1976年至1981年间香港男性鼻咽癌（NPC）死亡情况进行了一项研究。调查了不同职业群体中鼻咽癌死亡率的差异。过去十年中男性鼻咽癌的平均死亡率为每10万人中有14例，这是世界上最高的之一。使用年龄别死亡率和直接年龄标准化死亡率对职业群体进行比较，结果显示农业和渔业职业的死亡率越来越高（p<0.01），而行政职业的死亡率最低（p<0.05）。计算了职业的十个最高比例死亡率，结果显示渔民、水管工、焊工和钳工的比例死亡率显著较高。本文对这些发现的可能原因进行了回顾和讨论。
