  • Cancer in the Sami population of Sweden in relation to lifestyle and genetic factors

    • The reindeer herding Sami of Sweden have low incidences of cancer. The aim of the present study was to investigate the cancer risk in a large cohort of Swedish Sami, containing Sami with different lifestyle and genetic Sami heritage. A cohort of 41,721 Sami identified in official national registers between 1960 and 1997, was divided into two sub-populations -- reindeer herding Sami (RS) and non-reindeer herding Sami (NRS). A demographically matched non-Sami reference population (NS) was used as standard when incidence and mortality ratios were calculated. Incidence and mortality data were obtained from the Swedish Cancer and Cause of Death Registers for the period 1961-2003. For Sami men, lower risks were found for cancers of the colon and prostate, and for malignant melanoma and non-Hodkins lymphoma, but higher for stomach cancer. The Sami women showed higher risks for cancers of the stomach and the ovaries, but lower risk for cancer of the bladder. The RS demonstrated lower relative cancer risks compared with the NRS. The lowest relative risk was found among the RS men, while the highest were observed among the NRS women. The RS men who had adopted a more westernized lifestyle showed a similar relative risk for prostate cancer as that of the NS living in the same region. Most of these differences in cancer risks could probably be ascribed to differences in lifestyle. It is concluded that the traditional Sami lifestyle contains elements, e.g. dietary contents and physical activity that may protect them from developing cancer.

  • Stroke and acute myocardial infarction in the Swedish Sami population : incidence and mortality in relation to income and level of education
  • 2008
  • Ingår i: Scandinavian Journal of Public Health. - SAGE. - 1403-4948. ; 36:1, s. 84-91
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Gender differences in cardiovascular diseases (CVD) among the Sami have been reported previously. The aim of the present study was to investigate the incidence of and mortality from stroke, subarachnoid haemorrhage (SAH) and acute myocardial infarction (AMI) in the Swedish Sami population between 1985 and 2002, and to analyse the potential impact of income and level of education on the cardiovascular morbidity and mortality.Methods: A Sami cohort of 15,914 persons (4,465 reindeer herding and 11,449 non-herding Sami) were followed from 1985 to 2002 with respect to incidence and mortality rates of AMI, stroke and SAH. Incidence and mortality ratios were calculated using a demographically matched non-Sami control population (DMC) as the standard (71,550 persons).Results: There was no elevated risk for developing AMI among the Sami compared with the DMC. However, the mortality ratio of AMI was significantly higher for Sami women. Higher incidence rates of stroke and SAH for both Sami men and women was observed, but no differences in mortality rates. Apart from the reindeer herding men who demonstrated lower levels of income and education, the income and education levels among Sami were similar to the DMC.Conclusions: High mortality rates from AMI rather than stroke explain the excess mortality for CVD previously shown among Sami women. The results suggest that the differences in incidence of stroke between herding and non-herding Sami men, and between Sami women and non-Sami women, are caused by behavioural and psychosocial risk factors rather than by traditional socioeconomic ones.

  • Unnatural deaths in reindeer-herding Sami families in Sweden, 1961-2001
  • 2010
  • Ingår i: International Journal of Circumpolar Health. - 1239-9736. ; 69:2, s. 129-137
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives. Unnatural deaths among Indigenous populations, including the Swedish Sami, occur more often than among the general population. To find prevention strategies, we explored the circumstances of the unnatural deaths of members of reindeer-herding Sami families. Study design. The number of deaths from among a cohort of 7,482 members of reindeer-herding Sami families were retrieved from the National Board of Health and Welfare for the years 1961- 2001. Methods. An evaluation of the information from autopsy records at the National Board of Forensic Medicine, police reports, and available medical records identified 158 unnatural deaths. These were then analysed in detail. Results. Transport-related deaths and suicides were the most common unnatural deaths among Swedish reindeer-herding Sami family members. Suicides contributed to 23% of all deaths, road traffic accidents to 16%, and snowmobile fatalities to 11%. The accidents generally reflected an "outdoor lifestyle" and the working conditions were characterized by the use of off-road vehicles such as snowmobiles. Half of the number of victims tested positive for alcohol and alcohol abuse was documented in 15% of all victims. Conclusions. The results indicate that alcohol is an important factor in preventing unnatural deaths among reindeer-herding Sami, together with increased safety of both on-road and off-road transportation.
