挪威北部的萨米人是一个生活方式与其他人口不同的少数民族。挪威癌症登记处对 19801 名萨米人的队列进行了 19701997 年癌症发病率的跟踪调查。在萨米人中，观察到 1,340 例癌症病例，而根据区域参考人群预计为 1,658.2 例。对于两性来说，结肠癌的发病率均显着降低。男性的标准化发病率 (SIR) 为 0.50（95% 置信区间 (CI) 0.34-0.71），女性为 0.62（95% CI 0.43-0.85）。肺癌的 SIR 较低：男性和女性分别为 0.63 (95% CI 0.51-0.77) 和 0.60 (95% CI 0.37-0.91)。萨米血统的男性患前列腺癌的风险较低：SIR 0.57 (95% CI 0.45-0.71)。在女性中，观察到 127 例乳腺癌病例，而预期为 149.6 例。相对较高的体力活动和富含鱼类的饮食可能是癌症发病率较低的部分原因。一些萨米人因其以驯鹿产品为主的饮食而受到放射性影响。没有观察到对其癌症发病率的不利影响。 (C) 2005 年利平科特·威廉姆斯·威尔金斯。
The Sami population in North Norway constitutes an ethnic minority with a lifestyle that diverges from that of the rest of the population. A cohort of 19801 people of Sami origin was followed for cancer incidence over the period 19701997 by the Norwegian Cancer Registry. Among the Sami 1340 cases of cancer were observed versus 1658.2 expected, based on a regional reference population. For both sexes a significantly decreased incidence of colon cancer was observed. The standardized incidence ratio (SIR) for men was 0.50 (95% confidence interval (CI) 0.34-0.71) and for women 0.62 (95% CI 0.43-0.85). Low SIRs were observed for lung cancer: 0.63 (95% CI 0.51-0.77) and 0.60 (95% CI 0.37-0.91), for men and women, respectively. Men of Sami ancestry had a decreased risk of prostate cancer: SIR 0.57 (95% CI 0.45-0.71). Among women 127 cases of breast cancer were observed versus 149.6 expected. A relatively high physical activity and a diet rich in fish may in part explain the low cancer incidence. Some Sami were exposed to radioactivity as a result of their diet based on reindeer products. Adverse effects on their cancer incidence were not observed. (C) 2005 Lippincott Williams Wilkins.
