- OBJECTIVE: To investigate the occurrence of clinical, psychosocial and behavioural risk factors for cardiovascular diseases (CVD) among reindeer herding (RS) and non-reindeer herding Sami (NRS). STUDY DESIGN: A retrospective cohort study, comparing risk factors behind CVD between Sami and non-Sami, RS and NRS, and Sami men and women. METHODS: A cohort of 611 Swedish Sami (276 men and 335 women) was constructed from national population registers. A twice as large control cohort of non-Sami was created, matched by age, gender and area of residence. Information on risk factors was obtained from a database containing clinical and psychosocial-behavioural data from a regional CVD preventive programme for the period 1990-2001. RESULTS: The Sami and the non-Sami showed similar risk factor patterns. The main differences were related to working conditions and lifestyle factors of the RS. The RS men had lower blood pressure, were more physically active and had higher job demand and decision latitude. The RS women showed more negative scores on the indices of the job strain model. CONCLUSIONS: Previously reported differences in CVD mortality between Sami and non-Sami, and Sami men and women, can only partly be explained by different exposure to the psychosocial and behaviour risk factors investigated in this study.

- BACKGROUND: Indigenous people often have a pattern of mortality that is disadvantageous in comparison with the general population. The knowledge on causes of death among the Sami, the natives of northern Scandinavia, is limited. The aim of the present study was to compare gender and cause specific mortality patterns for reindeer herding Sami, non-herding Sami, and non-Sami between 1961 and 2000. METHODS: A Sami cohort was constructed departing from a group of index-Sami identified as either reindeer herding Sami or Sami eligible to vote for the Sami parliament. Relatives of index-Sami were identified in the National Kinship Register and added to the cohort. The cohort contained a total of 41 721 people (7482 reindeer herding Sami and 34 239 non-herding Sami). A demographically matched non-Sami reference population four times as large, was compiled in the same way. Relative mortality risks were analysed by calculating standardized mortality ratios (SMRs). RESULTS: The differences in overall mortality and life expectancy of the Sami, both reindeer herding and non-herding, compared with the reference population were relatively small. However, Sami men showed significantly lower SMR for cancers but higher for external causes of injury. For Sami women, significantly higher SMR was found for diseases of the circulatory system and diseases of the respiratory system. An increased risk of dying from subarachnoid haemorrhage was observed among both Sami men and women. CONCLUSIONS: The similarities in mortality patterns are probably a result of centuries of close interaction between the Sami and the non-Sami, while the observed differences might be due to lifestyle, psychosocial and/or genetic factors.

- Objective. Over the last decades, reindeer-herding management has experienced drarnatic changes, e.g. increased motorization and socio-econornic pressure. The airn of the present study was to investigate whether these changes have increased the risk of fatal, work-related accidents and suicide between 1961 and 2000. Study design and methods. A c oh ort containing 7,482 members of reindeer-herding Sami families was extracted from national population registers. Information on fatal accidents and suicide was obtained from the Swedish Causes of Death Register, and compared to the expected number of deaths in a dernographica11y matched control population of non-Sami. Results. The ffiale reindeer her- ding Sami showed a significantly increased risk of dying from accidents such as vehicle accidents and poisoning. No significant increased risk of suicide was observed. A comparison between the periods of 1961-1980 and 1981- 2000 showed non-significant differences in risk, although a trend towards incre- ased risks was observed for most types of external causes of death except suicide. Conclusions. It is suggested that the increased socio-econornic pressure and the extensive use of terrain vehicles have increased the risk for fatal accidents arnong Swedish reindeer herders, and that commercial reindeer ma- nagement is one of the most dangerous occupations in Sweden

- 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 cardiovascular morbidity and mortality. Methods: A Sami cohort of 15,914 persons (4,465 reindeer herding and 11,449 non-herding Sami) were followed up from 1985 to 2002 with regard 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 of 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.
