Participation in paid and unpaid work one year after injury and the impact of subsequent injuries for Māori: Results from a longitudinal cohort study in New Zealand

INTRODUCTION

Indigenous populations experience greater injury burdens than non-indigenous groups. This paper investigated, for injured Māori (New Zealand's indigenous population): 1) participation in paid and unpaid work 12 months after injury, 2) whether subsequent injuries are predictive of reduced participation, and 3) if particular characteristics of subsequent injuries predict reduced participation.

METHODS

The Subsequent Injury Study utilised data from the earlier Prospective Outcomes of Injury Study, a study of 2856 injured New Zealanders (including 566 Māori; 20%) who had an Accident Compensation Corporation (ACC; New Zealand's no-fault injury insurer) entitlement claim (sentinel injury). Data about subsequent injuries reported to ACC and hospital discharge data for injuries resulting in hospitalisation were also utilised. Multivariable models were used to examine if certain aspects of subsequent injury predicted either of two outcomes - reduced participation in paid, and unpaid work 12 months after a sentinel injury.

RESULTS

Eligible participants were identified from the 405 Māori participants interviewed at 12 months. Thirty-two percent sustained at least one ACC subsequent injury, and 16% reported reduced participation in unpaid work. Of the eligible participants working for pay at the time of their sentinel injury, 35% reported reduced participation in paid work. Although the relationship between sustaining a subsequent injury (or not) and reduced participation in paid work was unclear (aRR 1.4, 95%CI 0.9,2.3), particular subsequent injury characteristics were identified as being independently predictive: subsequent injury resulting from an assault (aRR 2.4, 95%CI 1.2,4.9), a subsequent injury involving an entitlement claim (aRR 2.0, 95%CI 1.1,3.4), sustaining more than one subsequent injury (aRR 2.0, 95%CI 1.1,3.6), and only non-work-related subsequent injuries (aRR 1.6, 95%CI 1.0,2.7).

CONCLUSIONS

Reduced participation in paid work is prevalent for Māori after an ACC entitlement claim injury. Particular characteristics of subsequent injuries after such an event impacts on participation in paid work 12 months after the sentinel injury, but the picture is less clear for unpaid work. Understanding the changes in paid and unpaid work, and the predictive characteristics of subsequent injuries for injured Māori, is important for future injury prevention strategies and supporting return to work rehabilitation programmes, specifically for Māori.

A population-based study on health and living conditions among Sámi in Sweden: the SámiHET study

The aim of this paper was to describe the study design, data collection procedure and participation of the population-based study “Sámi Health on Equal Terms” (SámiHET) conducted among the Sámi in Sweden in 2021. A Sámi sample was constructed, drawing from three pre-existing-registers: the Sámi electoral roll, the reindeer mark register and the “Labour statistics based on administrative sources” register to identify reindeer herding businesses. All identified persons aged 18–84 were invited to participate during February–May 2021. Among the 9,249 invitations, 3,779 answered the survey (participation rate of 40.9%). More women than men participated, and the age group 45–64 was the most common in both sexes. Around 10% of participants were in the youngest group. A majority of participants were residents of Norrbotten (48%), while almost one fourth were living outside Sápmi (22%). SámiHET has been demonstrated to be a feasible and cost-effective way of investigating health and living conditions among the Sámi in Sweden, providing information easy to compare with Swedish data. The knowledge to be produced may be used to inform policy to guide and improve Sámi health, thus contributing to realising the equal health rights of the Indigenous Sámi in Sweden.

Suicide rates amongst individuals from ethnic minority backgrounds: A systematic review and meta-analysis

BACKGROUND

Existing evidence suggests that some individuals from ethnic minority backgrounds are at increased risk of suicide compared to their majority ethnic counterparts, whereas others are at decreased risk. We aimed to estimate the absolute and relative risk of suicide in individuals from ethnic minority backgrounds globally.

METHODS

Databases (Medline, Embase, and PsycInfo) were searched for epidemiological studies between 01/01/2000 and 3/07/2020, which provided data on absolute and relative rates of suicide amongst ethnic minority groups. Studies reporting on clinical or specific populations were excluded. Pairs of reviewers independently screened titles, abstracts, and full texts. We used random effects meta-analysis to estimate overall, sex, location, migrant status, and ancestral origin, stratified pooled estimates for absolute and rate ratios. PROSPERO registration: CRD42020197940.

FINDINGS

A total of 128 studies were included with 6,026,103 suicide deaths in individuals from an ethnic minority background across 31 countries. Using data from 42 moderate-high quality studies, we estimated a pooled suicide rate of 12·1 per 100,000 (95% CIs 8·4-17·6) in people from ethnic minority backgrounds with a broad range of estimates (1·2-139·7 per 100,000). There was weak statistical evidence from 51 moderate-high quality studies that individuals from ethnic minority groups were more likely to die by suicide (RR 1·3 95% CIs 0·9-1·7) with again a broad range amongst studies (RR 0·2-18·5). In our sub-group analysis we only found evidence of elevated risk for indigenous populations (RR: 2·8 95% CIs 1·9-4·0; pooled rate: 23·2 per 100,000 95% CIs 14·7-36·6). There was very substantial heterogeneity (I²  > 98%) between studies for all pooled estimates.

INTERPRETATION

The homogeneous grouping of individuals from ethnic minority backgrounds is inappropriate. To support suicide prevention in marginalised groups, further exploration of important contextual differences in risk is required. It is possible that some ethnic minority groups (for example those from indigenous backgrounds) have higher rates of suicide than majority populations.

Examining the barriers and facilitators for Māori accessing injury and rehabilitation services: a scoping review protocol

INTRODUCTION

Injury accounts for 10% of the global burden of disease. While the literature is scarce, research investigating injury among Indigenous populations has found incidence and prevalence rates are higher, compared with non-Indigenous populations. New Zealand is no exception; Māori have higher rates of injury and disability compared with non-Māori. Given the burden of injury for Māori, this scoping review aims to identify, understand and map available literature related to the barriers and facilitators to accessing injury-related healthcare for Māori in New Zealand.

METHODS AND ANALYSIS

A scoping review will be conducted to identify the relevant literature and provide an opportunity to highlight key concepts and research gaps in the literature. This work will be guided by the scoping review framework developed by Arksey and O'Malley and will be underpinned by Kaupapa Māori research principles. The overall project is also be guided by a Māori advisory group. Database searches, for example, MEDLINE (Ovid), Scopus and Embase, will be used to identify empirical literature, and Google, New Zealand government websites and relevant non-government organisations will be used to identify relevant grey literature.

ETHICS AND DISSEMINATION

To the best of our knowledge, this scoping review is the first to systematically examine the currently available literature relating to the barriers and facilitators of accessing injury-related healthcare for Māori in New Zealand. Ethical approval was not required for this scoping review. Dissemination will include publication of the scoping review findings in a peer-reviewed journal, as well as presentations at conferences, to the project's advisory group, and staff working in the field of Māori disability and rehabilitation.

Indigenous Sami Family Caregivers' Experiences With Accessing and Collaborating With Municipal Health and Care Services

Previous research has indicated that Indigenous Sami families in Norway use public home-based care services less often than their non-Sami peers. Based on qualitative interviews with Sami family caregivers, we explore what they experience as barriers to accessing public care services for older adults living with dementia, and how they experience collaborating with care services providers. Through a reflexive thematic approach, we identified that rather than a cultural norm of "taking care of one's own," the underuse of public care services among Sami families were related to several intertwined circumstances. The Sami family caregivers reported barriers to accessing public care, such as lack of familiarity with the services and cultural and language concerns and the legacy of history, and drivers for continuing family care, such as blurred distribution of responsibility, lack of continuity of care, and culturally unsafe caring environments and marginalizing practices.

"Mapping suicide prevention initiatives targeting Indigenous Sámi in Nordic countries"

BACKGROUND

Suicide is a major public health issue among Indigenous Sámi in Nordic countries, and efforts to prevent suicide in the Sámi context are increasing. However, there is no literature on suicide prevention initiatives among Sámi. The aim of the study was to map suicide prevention initiatives targeting Sámi in Norway, Sweden, and Finland during 2005-2019.

METHOD

Initiatives were identified and described through utilizing networks among stakeholders in the field of suicide prevention among Sámi, acquiring documentation of initiatives and utilizing the authors first-hand experiences. The described initiatives were analyzed inspired by the "What is the problem represented to be?" (WPR)-approach.

RESULTS

Seventeen initiatives targeting Sámi were identified during 2005-2019, including nine in Sweden, five in Norway, one in Finland and two international initiatives. Analysis with the WPR-approach yielded 40 problematizations regarding how to prevent suicide among Sámi, pertaining to shortcomings on individual (5), relational (15), community/cultural (3), societal (14) and health systems levels (3). All initiatives were adapted to the Sámi context, varying from tailor-made, culture-specific approaches to targeting Sámi with universal approaches. The most common approaches were the gatekeeper and mental health literacy training programs. The initiatives generally lacked thorough evaluation components.

CONCLUSION

We argue that the dominant rationales for suicide prevention were addressing shortcomings on individual and relational levels, and raising awareness in the general public. This threatens obscuring other, critical, approaches, such as broadening perspectives in prevention planning, improving health systems for Sámi, and promoting cultural empowerment among Sámi. Nevertheless, the study confirms considerable efforts have been invested into suicide prevention among Sámi during the last 15 years, and future initiatives might include a broader set of prevention rationales. To improve evaluation and identify the most promising practices, increased support regarding development of plans and implementation of evaluation components is needed.

"If the reindeer die, everything dies": The mental health of a Sámi community exposed to a mining project in Swedish Sápmi

In 2006, a British mining company started the process of extracting ore from Gállok/Kallak, in Swedish Sápmi. These grounds are used all year round for reindeer herding by the Sámi community Jåhkågasska tjiellde. While environmental impact assessments should be conducted by law in any development project in Sweden, the health component included is usually vague. The aim of this study was to understand the experiences and perceptions of the Sámi community regarding the current and potential health effects of the proposed mine.A qualitative study, including six in-depth interviews with members of the community, was conducted in 2020. Interviews were analysed using thematic analysis. Five themes were identified and organised in current and future impacts. Current impacts included “It’s like David’s battle against Goliath”, “It’s a slow process that takes a lot of power and energy”, “It’s a defense … like, to protect oneself”; with future impacts including: “If the reindeer die, everything dies”, “You would feel that you do not possess any power, [you would feel] overridden, pushed away, not liked”.The fear of losing current and future generations’ livelihoods appeared to be the main mediators of the current and potential worsened mental health experienced by the community.

A Salutogenic Perspective on End-of-Life Care among the Indigenous Sámi of Northern Fennoscandia

There is limited empirical data about both health and end-of-life (EoL) issues among the Indigenous Sámi of Fennoscandia. We therefore aimed to investigate experiences of EoL care and support among the Sámi, both from the Sámi community itself as well as from more formalized health and social care services in Sweden. Our primary data source is from focus group discussions (FGDs) held at a Sámi event in 2017 with 24 people, complemented with analysis of previously collected data from 15 individual interviews with both Sámi and non-Sámi informants familiar with dying, death and bereavement among Sámi; "go-along" discussions with 12 Sámi, and individual interviews with 31 Sámi about advance care planning. After initial framework analysis, we applied a salutogenic model for interpretation, focusing on a sense of community coherence. We found a range of generalized resistance resources in relation to the Sámi community, which appeared to support EoL care situations, i.e., Social Organization; Familiarity with EoL Care, Collective Cultural Heritage; Expressions of Spirituality; Support from Majority Care Systems; and Brokerage. These positive features appear to support key components of a sense of community coherence, i.e., comprehensibility, meaningfulness and manageability. We also found relatively few, but notable deficits that may diminish the sense of community coherence, i.e., lack of communication in one's own language; orientation, familiarity and/or agreement in contacts with formal health and social care systems; and/or support from extended family. The results suggest that there is a robust basis among Sámi for well-functioning EoL care; a challenge is in developing supportive interactions with the majority health and social care systems that support and complement these structures, for partnership in developing care that is meaningful, comprehensible and manageable even in potentially difficult EoL situations.

POIS-10 Māori: Outcomes and Experiences in the Decade Following Injury

Injury-related disability burden extends well beyond two years post-injury, especially for Māori (Indigenous) New Zealanders. Māori also experience greater difficulty accessing health services. This prospective cohort study extension uses mixed-methods and aims to understand and identify factors contributing to long-term experiences and outcomes (positive and negative) at 12 years post-injury for injured Māori and their whānau (families), and explore the barriers and facilitators to whānau flourishing, and access to health and rehabilitation services. Five hundred and sixty-six Māori, who were injured between 2007-2009, participated in the Prospective Outcomes of Injury Study (POIS). Of these, 544 consented to long-term follow up, and will be invited to participate in a POIS-10 Māori interview at 12 years post-injury. We anticipate a 65% follow-up rate (~n = 350). Aligned with the Meihana Model, interviews will collect information about multiple inter-related dimensions. Administrative injury and hospitalisation data up to 12 years post-injury will also be collected. Regression models will be developed to examine predictors of long-term health and disability outcomes, after adjusting for a range of confounders. POIS-10 Māori will identify key points in the injury and rehabilitation pathway to inform future interventions to improve post-injury outcomes for Māori and whānau, and will highlight the support required for Māori flourishing post-injury.

Suicide among reindeer herding Sámi in Sweden, 1961-2017

This study analyses suicides amongst reindeer herding Sámi in Sweden using information from the database of the National Board of Forensic Medicine. Suicides were identified using registers (39 suicides from 1961–2000) and key informants (11 suicides from 2001–2017). A great majority of cases were males (43 males, 7 females), and 50% occurred in the northernmost region. The mean age was 37.4 years with a peak in the group 20–29 years of age. Shooting was the most common (56%) method, followed by hanging. Blood alcohol concentration measures available from 1993 were above 0.2 g/l in 76% of the cases. There was a maximum incidence of suicides between 1981 and 1990. An accumulation of suicides in the months of May (N = 8) and November (N = 7) was seen. The annual suicide rate was estimated to be between 17.5 and 43.9 per 100 000 population. There was a clear gradient in suicide incidence with the highest being in the southernmost region (Jämtland/Härjedalen) and the lowest in the northernmost county (Norrbotten). For strengthened suicide prevention in this group, future research should address sex differences, the role of alcohol use and the general conditions for reindeer herding.

Disparities amidst plenty: a health portrait of Indigenous peoples in circumpolar regions

This paper describes the extent and variation in health disparities between Indigenous and non-Indigenous people within Alaska, Greenland and the northern regions of Canada, Russia and the Nordic countries. We accessed official health statistics and reviewed research studies. We selected a few indicators of health status, health determinants and health care to demonstrate the health disparities that exist. For a large number of health indicators Indigenous people fare worse than non-Indigenous people in the same region or nationally, with the exception of the Sami in the Nordic countries whose health profiles are similar to their non-Sami neighbours. That we were unable to produce a uniform set of indicators applicable to all regions is indicative of the large knowledge gaps that exist. The need for ongoing health monitoring for Indigenous people is most acute for the Sami and Russia, less so for Canada, and least for Alaska, where health data specific to Alaska Natives are generally available. It is difficult to produce an overarching explanatory model for health disparities that is applicable to all regions. We need to seek explanation in the broader political, cultural and societal contexts within which Indigenous people live in their respective regions.

Somatic health in the Indigenous Sami population - a systematic review

The objective of this systematic review was to survey the current scientific knowledge regarding the state of somatic health among the Indigenous Sami people in Norway, Finland, Sweden and the Kola Peninsula in Russia; and assess the quality of the identified studies. A systematic search in the databases Pubmed, EBSCOhost (AMED, Medline, Cinahl) and Svemed was conducted from January 2000, through December 2017. This systematic search identified 399 articles. After screening abstracts, 93 articles were reviewed in full text, 32 of which met the inclusion criteria. The scientific quality of the evidence was rated according to the Newcastle–Ottawa scale. Based on the studies with moderate to high scientific quality, there is evidence for stating that the majority of the Sami included in this review experience good health. Mortality and life expectancy are similar, with only minor differences, to those of a non-Sami population. The cancer risk rate among Sami was lower than that of the general population of Norway, Sweden and Finland. Self-reported myocardial infarction prevalence was similar between Sami and non-Sami, but Angina pectoris was more prevalent among Sami. In Sweden, cardiovascular disease rates were similar between Sami and non-Sami. Musculoskeletal pain symptoms are common among the Sami population, as are obesity and overweight. To conclude, there are knowledge gaps in regard to the somatic health situation of the Indigenous Sami in the circumpolar area, especially in Russia, Finland and Sweden; as current knowledge is mainly based on publications from the SAMINOR study in Norway. No study obtained the highest quality score, suggesting a need to implement longitudinal prospective studies.

Towards estimating the indigenous population in circumpolar regions

Despite the importance of indigenous people in the Arctic, there is no accurate estimate of their size and distribution. We defined indigenous people as those groups represented by the “permanent participants” of the Arctic Council. The census in Canada, Russia and the United States records status as an indigenous person. In Greenland, a proxy measure is place of birth supplemented by other information. For the Nordic countries we utilized a variety of sources including registered voters’ lists of the various Sami parliaments and research studies that established Sami cohorts. Overall, we estimated that there were about 1.13 million indigenous people in the northern regions of the 8 Member States of the Arctic Council. There were 8,100 Aleuts in Alaska and the Russian North; 32,400 Athabaskans in Alaska and northern Canada; 145,900 Inuit in Alaska, northern Canada and Greenland; 76,300 Sami in northern Norway, Sweden, Finland and Russia; and 866,400 people in northern Russia belonging to other indigenous groups. Different degrees and types of methodological problems are associated with estimates from different regions. Our study highlights the complexity and difficulty of the task and the considerable gaps in knowledge. We hope to spur discussion of this important issue which could ultimately affect strategies to improve the health of circumpolar peoples.

Season of birth, stillbirths, and neonatal mortality in Sweden: the Sami and non-Sami population, 1800-1899

Seasonal patterns of neonatal mortality and stillbirths have been found around the world. However, little is known about the association between season of birth and infant mortality of pre-industrial societies in a subarctic environment. In this study, we compared how season of birth affected the neonatal and stillbirth risk among the Sami and non-Sami in Swedish Sápmi during the nineteenth century. Using digitised parish records from the Demographic Data Base at Umeå University, we applied logistic regression models for estimating the association of season of birth with stillbirths and neonatal mortality, respectively. Higher neonatal mortality was found among the winter- and autumn-born Sami, compared to summer-born infants. Stillbirth risk was higher during autumn compared to summer among the Sami, whereas we found no seasonal differences in mortality among the non-Sami population. We relate the higher neonatal mortality risk among winter-born Sami to differences in seasonality of living conditions associated with reindeer herding.

"If you do not birget [manage] then you don't belong here": a qualitative focus group study on the cultural meanings of suicide among Indigenous Sámi in arctic Norway

Suicide is a major public health issue across the Arctic, especially among Indigenous Peoples. The aim of this study was to explore and describe cultural meanings of suicide among Sámi in Norway. Five open-ended focus group discussions (FGDs) were conducted with 22 Sámi (20) and non-Sámi (2) participants in South, Lule, Marka, coastal and North Sámi communities in Norway. FGDs were recorded, transcribed verbatim and analysed employing thematic analysis. Six themes were developed from the analysis: “Sámi are treated negatively by the majority society”, “Some Sámi face negative treatment from other Sámi”, “The historic losses of the Sámi have turned into a void”, “Sámi are not provided with equal mental health care”, “The strong Sámi networks have both positive and negative impacts” and “‘Birgetkultuvvra’ might be a problem”. The findings indicate that the participants understand suicide among Sámi in relation to increased problem load for Sámi (difficulties in life not encountered by non-Sámi) and inadequate problem-solving mechanisms on different levels, including lack of equal mental health care for Sámi and cultural values of managing by oneself (“ieš birget”). The findings are important when designing suicide prevention initiatives specifically targeting Sámi.

Global goals and suicide prevention in the Circumpolar North

The purpose of this selective narrative review is to provide an overview of suicide and suicide prevention in the Circumpolar North and the relevance of global strategies and policies to these themes. We conducted a selective review of the English language literature on Arctic Indigenous mental health, suicide, and suicide prevention. We briefly present the social context, epidemiology, and risk and protective factors for suicide in the Arctic, with a focus on Indigenous peoples. We highlight a recent collaborative, intergovernmental response to elevated suicide rates in this region, the Reducing the Incidence of Suicide in Indigenous Groups - Strengths United through Networks Initiative, which used a consensus methodology to identify key outcomes for evaluating suicide prevention interventions in the circumpolar context. In relation to the Sustainable Development Goals, we examine recent policy developments in Indigenous-led suicide prevention and identify opportunities for strengthening policy, community interventions, and research. Globally, suicide prevention is a public health priority, and reducing the number of suicide deaths is a key target for sustainable development. Although overall and country-specific suicide rates have decreased since 1990, there remains wide variation at the regional and local level. This is particularly evident in the Arctic region known as the Circumpolar North, where Indigenous peoples experience marked disparities in suicide risk and suicide deaths compared to non-Indigenous populations. The factors that influence these variations are complex and often rooted in the social and economic consequences of colonization. The integration of science, community-based and Indigenous knowledge, and policies that address upstream risks for suicide will play an important role in suicide prevention alongside the growing number of Indigenous suicide prevention strategies tailored for specific populations.

The Holistic Effects of Climate Change on the Culture, Well-Being, and Health of the Saami, the Only Indigenous People in the European Union

PURPOSE OF REVIEW

(1) To develop a framework for understanding the holistic effects of climate change on the Saami people; (2) to summarize the scientific evidence about the primary, secondary, and tertiary effects of climate change on Saami culture and Sápmi region; and (3) to identify gaps in the knowledge of the effects of climate change on health and well-being of the Saami.

RECENT FINDINGS

The Saami health is on average similar, or slightly better compared to the health of other populations in the same area. Warming climate has already influenced Saami reindeer culture. Mental health and suicide risk partly linked to changing physical and social environments are major concerns. The lifestyle, diet, and morbidity of the Saami are changing to resemble the majority populations posing threats for the health of the Saami and making them more vulnerable to the adverse effects of climate change. Climate change is a threat for the cultural way of life of Saami. Possibilities for Saami to adapt to climate change are limited.

In the light of change: a mixed methods investigation of climate perceptions and the instrumental record in northern Sweden

Significant climate change in the Arctic has been observed by indigenous peoples and reported in scientific literature, but there has been little research comparing these two knowledge bases. In this study, Sami reindeer herder interviews and observational weather data were combined to provide a comprehensive description of climate changes in Northern Sweden. The interviewees described warmer winters, shorter snow seasons and cold periods, and increased temperature variability. Weather data supported three of these four observed changes; the only change not evident in the weather data was increased temperature variability. Winter temperatures increased, the number of days in cold periods was significantly reduced, and some stations displayed a 2 month-shorter snow cover season. Interviewees reported that these changes to the wintertime climate are significant, impact their identity, and threaten their livelihood. If consistency between human observations of changing weather patterns and the instrumental meteorological record is observed elsewhere, mixed methods research like this study can produce a clearer, more societally relevant understanding of how the climate is changing and the impacts of those changes on human well-being.

Global incidence of suicide among Indigenous peoples: a systematic review

BACKGROUND

Suicide is the second leading cause of death among adolescents worldwide, and is a major driver of health inequity among Indigenous people in high-income countries. However, little is known about the burden of suicide among Indigenous populations in low- and middle-income nations, and no synthesis of the global data is currently available. Our objective was to examine the global incidence of suicide among Indigenous peoples and assess disparities through comparisons with non-Indigenous populations.

METHODS

We conducted a systematic review of suicide rates among Indigenous peoples worldwide and assessed disparities between Indigenous and non-Indigenous populations. We performed text word and Medical Subject Headings searches in PubMed, MEDLINE, Embase, Cumulative Index of Nursing and Allied Health (CINAHL), PsycINFO, Latin American and Caribbean Health Sciences Literature (LILACS), and Scientific Electronic Library Online (SciELO) for observational studies in any language, indexed from database inception until June 1, 2017. Eligible studies examined crude or standardized suicide rates in Indigenous populations at national, regional, or local levels, and examined rate ratios for comparisons to non-Indigenous populations.

RESULTS

The search identified 13,736 papers and we included 99. Eligible studies examined suicide rates among Indigenous peoples in 30 countries and territories, though the majority focused on populations in high-income nations. Results showed that suicide rates are elevated in many Indigenous populations worldwide, though rate variation is common, and suicide incidence ranges from 0 to 187.5 suicide deaths per 100,000 population. We found evidence of suicide rate parity between Indigenous and non-Indigenous populations in some contexts, while elsewhere rates were more than 20 times higher among Indigenous peoples.

CONCLUSIONS

This review showed that suicide rates in Indigenous populations vary globally, and that suicide rate disparities between Indigenous and non-Indigenous populations are substantial in some settings but not universal. Including Indigenous identifiers and disaggregating national suicide mortality data by geography and ethnicity will improve the quality and relevance of evidence that informs community, clinical, and public health practice in Indigenous suicide prevention.

Distribution of risk factors for cardiovascular disease and the estimated 10-year risk of acute myocardial infarction or cerebral stroke in Sami and non-Sami populations: The SAMINOR 2 Clinical Survey

Objective: This study aimed to assess and compare the distribution of cardiovascular risk factors and the estimated 10-year risk of fatal or non-fatal acute myocardial infarction (AMI) or cerebral stroke (CS) among the Sami and non-Sami populations of Northern Norway. Methods: The SAMINOR 2 Clinical Survey is a cross-sectional survey conducted in 10 municipalities in the counties of Finnmark, Troms and Nordland in rural Northern Norway in 2012–2014. All inhabitants aged 40–79 years were invited to participate, and 6004 (48.2%) accepted. The NORRISK 2 model was used to estimate the 10-year risk of fatal or non-fatal AMI or CS. Sex and age were included in the model, as well as the following risk factors for cardiovascular disease (CVD): serum total cholesterol, serum high-density lipoprotein cholesterol, systolic blood pressure, smoking habits and anti-hypertensive treatment. Results: Only minor ethnic differences were observed between Sami and non-Sami populations in a number of individual risk factors for CVDs. Overall, the NORRISK 2 model revealed no ethnic differences in the 10-year risk of AMI or CS. Conclusions:There were no differences in 10-year risk of AMI or CS between the Sami and non-Sami populations in 10 selected municipalities in Northern Norway.

Measuring cancer in indigenous populations

It is estimated that there are 370 million indigenous peoples in 90 countries globally. Indigenous peoples generally face substantial disadvantage and poorer health status compared with nonindigenous peoples. Population-level cancer surveillance provides data to set priorities, inform policies, and monitor progress over time. Measuring the cancer burden of vulnerable subpopulations, particularly indigenous peoples, is problematic. There are a number of practical and methodological issues potentially resulting in substantial underestimation of cancer incidence and mortality rates, and biased survival rates, among indigenous peoples. This, in turn, may result in a deprioritization of cancer-related programs and policies among these populations. This commentary describes key issues relating to cancer surveillance among indigenous populations including 1) suboptimal identification of indigenous populations, 2) numerator-denominator bias, 3) problems with data linkage in survival analysis, and 4) statistical analytic considerations. We suggest solutions that can be implemented to strengthen the visibility of indigenous peoples around the world. These include acknowledgment of the central importance of full engagement of indigenous peoples with all data-related processes, encouraging the use of indigenous identifiers in national and regional data sets and mitigation and/or careful assessment of biases inherent in cancer surveillance methods for indigenous peoples.

Injuries to Aboriginal populations living on- and off-reserve in metropolitan and non-metropolitan areas in British Columbia, Canada: Incidence and trends, 1986-2010

BACKGROUND

Disparities in injury rates between Aboriginal and non-Aboriginal populations in British Columbia (BC) are well established. Information regarding the influence of residence on disparities is scarce. We sought to fill these gaps by examining hospitalization rates for all injuries, unintentional injuries and intentional injuries across 24 years among i) Aboriginal and total populations; ii) populations living in metropolitan and non-metropolitan areas; and iii) Aboriginal populations living on- and off-reserve.

METHODS

We used data spanning 1986 through 2010 from BC's universal health care insurance plan, linked to vital statistics databases. Aboriginal people were identified by insurance premium group and birth and death record notations, and their residence was determined by postal code. "On-reserve" residence was established by postal code areas associated with an Indian reserve or settlement. Health Service Delivery Areas (HSDAs) were classified as "metropolitan" if they contained a population of at least 100,000 with a density of 400 or more people per square kilometre. We calculated the crude hospitalization incidence rate and the Standardized Relative Risk (SRR) of hospitalization due to injury standardizing by gender, 5-year age group, and HSDA. We assessed cumulative change in SRR over time as the relative change between the first and last years of the observation period.

RESULTS

Aboriginal metropolitan populations living off-reserve had the lowest SRR of injury (2.0), but this was 2.3 times greater than the general British Columbia metropolitan population (0.86). For intentional injuries, Aboriginal populations living on-reserve in non-metropolitan areas were at 5.9 times greater risk than the total BC population. In general, the largest injury disparities were evident for Aboriginal non-metropolitan populations living on-reserve (SRR 3.0); 2.5 times greater than the general BC non-metropolitan population (1.2). Time trends indicated decreasing disparities, with Aboriginal non-metropolitan populations experiencing the largest declines in injury rates.

CONCLUSIONS

Metropolitan/non-metropolitan residence appears to be a more important predictor than on/off-reserve residence for all injuries and unintentional injuries, and the relationship was even more pronounced for intentional injuries. The persistent disparities highlight the need for culturally sensitive and geographically relevant injury prevention approaches.

Aboriginal community-level predictors of injury-related hospitalizations in British Columbia, Canada

Population-level statistics indicating disparities in injury rates between Aboriginal and non-Aboriginal populations disguise considerable community-level heterogeneity. Using an ecological approach, we analyzed linked data from British Columbia's (BC) universal health care insurance plan, worker compensation, vital statistics, and census databases to identify community-level risk markers for hospitalization due to injury among the Aboriginal population of BC, Canada. Community standardized relative risks (SRR) of injury hospitalization relative to the total population of BC ranged from 0.24 to 9.35. Variables associated with increased SRRs included the following: higher proportions of crowded housing, housing in poor condition, participating in industries with greater risk of a work injury claim, being more remote, and at higher latitude. Higher income and more high school graduates were protective. In the best-fitting multivariable model, variables independently associated with SRR were proportion of the population with a high school certificate (RR = 0.89 per unit standard deviation change, 95 % confidence interval 0.83 to 0.94), and remoteness index (RR = 1.06, 95 % confidence interval (CI) 1.01 to 1.11). Results confirm profound diversity in Aboriginal communities across BC. SRRs of injury hospitalization increased as proportion of high school graduates dropped and remoteness increased. Promoting the educational attainment of community members should be an important focus of initiatives to improve health.

Suicide in circumpolar regions: an introduction and overview

This extended editorial introduces the Special Issue on Suicide and Resilience in Circumpolar Regions, the results of the knowledge synthesis project by an international research team funded by the Canadian Institutes of Health Research and endorsed by the Arctic Council. It focuses on the extent and magnitude of the problem of suicidal behaviours and thoughts from a circumpolar perspective – the variation across Arctic States and their northern regions, the excess risk among some indigenous groups and their demographic characteristics. Much remains to be learned about the design and implementation of youth-focused intervention programmes, especially in a circumpolar comparative framework.

Ethnic discrimination and health: the relationship between experienced ethnic discrimination and multiple health domains in Norway's rural Sami population

OBJECTIVE

Self-reported ethnic discrimination has been associated with a range of health outcomes. This study builds on previous efforts to investigate the prevalence of self-reported ethnic discrimination in the indigenous (Sami) population, and how such discrimination may be associated with key health indicators.

STUDY DESIGN

The study relies on data from the 2003/2004 (n=4,389) population-based study of adults (aged 36-79 years) in 24 rural municipalities of Central and North Norway (the SAMINOR study). Self-reported ethnic discrimination was measured using the question: "Have you ever experienced discrimination due to your ethnic background?" Health indicators included questions regarding cardiovascular disease, diabetes, chronic muscle pain, metabolic syndrome and obesity. Logistic regression was applied to examine the relationship between self-reported ethnic discrimination and health outcomes.

RESULTS

The study finds that for Sami people living in minority areas, self-reported ethnic discrimination is associated with all the negative health indicators included in the study.

CONCLUSION

We conclude that ethnic discrimination affects a wide range of health outcomes. Our findings highlight the importance of ensuring freedom from discrimination for the Sami people of Norway.

Prevalence of self-reported myocardial infarction in Sami and non-Sami populations: the SAMINOR study

Objective

Measure the prevalence of self-reported myocardial infarction (SMI) in Sami and non-Sami populations in rural areas of Norway, and explore whether possible ethnic differences could be explained by established cardiovascular risk factors.

Design

Cross-sectional population-based study.

Methods

A health survey was conducted in 2003–2004 in areas with Sami and non-Sami populations (SAMINOR). The response rate was 60.9%. Information concerning lifestyle was collected by 2 self-administrated questionnaires, and clinical examinations provided anthropometric measurements, and data on blood pressure and lipid levels.

Results

The total number for the subsequent analysis was 15,206 men and women aged 36–79 years (born 1925–1968). Sex-specific analyses revealed no ethnic difference in SMI. In terms of the most important risk factors such as smoking, blood pressure, and lipid levels, no or only trivial ethnic differences were found in both women and men.

Conclusion

In this study, we found no difference in SMI between Sami and non-Sami in rural areas in Norway. The similar risk profile is the most plausible explanation; similar living conditions and close interaction between the ethnic groups may explain this.

Ethnic difference in the prevalence of angina pectoris in Sami and non-Sami populations: the SAMINOR study

Objective

To assess the population burden of angina pectoris symptoms (APS), self-reported angina and a combination of these, and explore potential ethnic disparity in their patterns. If differences in APS were found between Sami and non-Sami populations, we aimed at evaluating the role of established cardiovascular risk factors as mediating factors.

Design

Cross-sectional population-based study.

Methods

A health survey was conducted in 2003–2004 in areas with Sami and non-Sami populations (SAMINOR). The response rate was 60.9%. The total number for the subsequent analysis was 15,206 men and women aged 36–79 years (born 1925–1968). Information concerning lifestyle was collected by 2 self-administrated questionnaires, and clinical examinations provided data on waist circumference, blood pressure and lipid levels.

Results

This study revealed an excess of APS, self-reported angina and a combination of these in Sami relative to non-Sami women and men. After controlling for age, the odds ratio (OR) for APS was 1.42 (p<0.001) in Sami women and 1.62 (p<0.001) for men. When including relevant biomarkers and conventional risk factors, little change was observed. When also controlling for moderate alcohol consumption and leisure-time physical activity, the OR in women was reduced to 1.24 (p=0.06). Little change was observed in men.

Conclusion

This study revealed an excess of APS, self-reported angina and a combination of these in Sami women and men relative to non-Sami women and men. Established risk factors explained little or none of the ethnic variation in APS. In women, however, less moderate alcohol consumption and leisure-time physical activity in Sami may explain the entire ethnic difference.

Cultural adaptations to the differential threats posed by hot versus cold climates

Hot and cold climates have posed differential threats to human survival throughout history. Cold temperatures can pose direct threats to survival in themselves, whereas hot temperatures may pose threats indirectly through higher prevalence of infectious disease. These differential threats yield convergent predictions for the relationship between more demanding climates and freedom of expression, but divergent predictions for freedom from discrimination.

Disparities in fatal and non-fatal injuries between Irish travellers and the Irish general population are similar to those of other indigenous minorities: a cross-sectional population-based comparative study

OBJECTIVES

To assess recent disparities in fatal and non-fatal injury between travellers and the general population in Ireland.

DESIGN

A cross-sectional population-based comparative study.

SETTING

Republic of Ireland.

PARTICIPANTS

Population census and retrospective mortality data were collected from 7042 traveller families, travellers being those identified by themselves and others as members of the traveller community. Retrospective injury incidence was estimated from a survey of a random sample of travellers in private households, aged 15 years or over (702 men and 961 women). Comparable general population data were obtained from official statistical reports, while retrospective incidence was estimated from the Survey of Lifestyle, Attitude and Nutrition 2002, a random sample of 5992 adults in private households aged 18 years or over.

OUTCOME MEASURES

Potential Years of Life Lost (PYLL), Standardised Mortality Ratios (SMR), Standardised Incidence Ratios (SIR) and Case Fatality Ratios (CFR).

RESULTS

Injury accounted for 36% of PYLL among travellers, compared with 13% in the general population. travellers were more likely to die of unintentional injury than the general population (SMR=454 (95% CI 279 to 690) in men and 460 (95% CI 177 to 905) in women), with a similar pattern for intentional injury (SMR=637 (95% CI 367 to 993) in men and 464 (95% CI 107 to 1204 in women). They had a lower incidence of unintentional injury but those aged 65 years or over were about twice as likely to report an injury. Travellers had a higher incidence of intentional injuries (SIR=181 (95% CI 116 to 269) in men and 268 (95% CI 187 to 373) in women). Injury CFR were consistently higher among travellers.

CONCLUSIONS

Irish travellers continue to bear a disproportionate burden of injury, which calls for scaling up injury prevention efforts in this group. Prevention and further research should focus on suicide, alcohol misuse and elderly injury among Irish travellers.

Suicidal expressions in young Swedish Sami, a cross-sectional study

Objectives

To investigate the experience of suicidal expressions (death wishes, life weariness, ideation, plans and attempts) in young Swedish Sami, their attitudes toward suicide (ATTS), and experience of suicidal expressions and completed suicide in significant others and to compare with Swedes in general.

Methods

A cross-sectional study comprising 516 Swedish Sami, 18–28 years of age together with an age and geographically matched reference group (n=218). Parts of the ATTS questionnaire have been used to cover different aspects of the suicidal complex.

Data were analysed with regard to gender, occupation, counties and experience of negative societal treatment due to Sami background.

Results

Both young Sami and young Swedes reported suicidal ideation, life weariness, and death wishes in a high degree (30–50%), but it was more common among the Sami. Having had plans to commit suicide showed a significant gender difference only in the Sami. The prevalence of suicide attempts did not differ significantly between Sami and Swedes. Subgroups of the Sami reported a higher degree of suicidal behaviour, Sami women and reindeer herders reported a 3, 5-fold higher odds of suicide attempts and a 2-fold higher odds having had plans committing suicide. Sami living in Vasterbotten/Jamtland/Vasternorrland and Sami with experience of ethnicity related bad treatment 2-fold higher odds of suicidal plans compared to those living in other counties.

Conclusion

An increased occurrence of suicidal ideation/death wishes/life weariness in young Sami compared to young majority Swedes was found, but not an increased prevalence of suicide attempts and positive attitudes together with an increased awareness to handle suicide problems could be a contributing factor. Severe circumstances and experience of ethnicity-related bad treatment seems to contribute to increased levels of suicidal plans and attempts in subgroups of Sami.

The confidence in health care and social services in northern Sweden--a comparison between reindeer-herding Sami and the non-Sami majority population

AIMS

To investigate the confidence in primary health care, psychiatry and social services among the reindeer-herding Sami and the non-Sami population of northern Sweden.

METHODS

A semi-randomized, cross-sectional study design comprising 325 reindeer-herding Sami (171 men, 154 women) and a control population of 1,437 non-Sami (684 men, 753 women). A questionnaire on the confidence in primary health care, psychiatry, social services, and work colleagues was distributed to members of reindeer-herding families through the Sami communities and to the control population through the post. The relative risk for poor confidence was analyzed by calculating odds ratios with 95% confidence intervals adjusted for age and level of education.

RESULTS

The confidence in primary health care and psychiatry was significantly lower among the reindeer-herding Sami compared with the control group. No differences were found between men and women in the reindeer-herding Sami population. In both the reindeer-herding Sami and the control population, younger people (≤ 48 years) reported significantly lower confidence in primary health care than older individuals (>48 years).

CONCLUSIONS

A conceivable reason for the poor confidence in health care organizations reported by the reindeer-herding Sami is that they experience health care staff as poorly informed about reindeer husbandry and Sami culture, resulting in unsuitable or unrealistic treatment suggestions. The findings suggest that the poor confidence constitutes a significant obstacle of the reindeer-herding Sami to fully benefit from public health care services.

Survival of Sami cancer patients

Objectives

The incidence of cancer among the indigenous Sami people of Northern Finland is lower than among the Finnish general population. The survival of Sami cancer patients is not known, and therefore it is the object of this study.

Study design

The cohort consisted of 2,091 Sami and 4,161 non-Sami who lived on 31 December 1978 in the two Sami municipalities of Inari and Utsjoki, which are located in Northern Finland and are 300–500 km away from the nearest central hospital. The survival experience of Sami and non-Sami cancer patients diagnosed in this cohort during 1979–2009 was compared with that of the Finnish patients outside the cohort.

Methods

The Sami and non-Sami cancer patients were matched to other Finnish cancer patients for gender, age and year of diagnosis and for the site of cancer. An additional matching was done for the stage at diagnosis. Cancer-specific survival analyses were made using the Kaplan–Meier method and Cox regression modelling.

Results

There were 204 Sami and 391 non-Sami cancer cases in the cohort, 20,181 matched controls without matching with stage, and 7,874 stage-matched controls. In the cancer-specific analysis without stage variable, the hazard ratio for Sami was 1.05 (95% confidence interval 0.85–1.30) and for non-Sami 1.02 (0.86–1.20), indicating no difference between the survival of those groups and other patients in Finland. Likewise, when the same was done by also matching the stage, there was no difference in cancer survival.

Conclusion

Long distances to medical care or Sami ethnicity have no influence on the cancer patient survival in Northern Finland.

A traditional Sami diet score as a determinant of mortality in a general northern Swedish population

OBJECTIVES

To examine the relationship between "traditional Sami" dietary pattern and mortality in a general northern Swedish population.

STUDY DESIGN

Population-based cohort study.

METHODS

We examined 77,319 subjects from the Västerbotten Intervention Program (VIP) cohort. A traditional Sami diet score was constructed by adding 1 point for intake above the median level of red meat, fatty fish, total fat, berries and boiled coffee, and 1 point for intake below the median of vegetables, bread and fibre. Hazard ratios (HR) for mortality were calculated by Cox regression.

RESULTS

Increasing traditional Sami diet scores were associated with slightly elevated all-cause mortality in men [Multivariate HR per 1-point increase in score 1.04 (95% CI 1.01-1.07), p=0.018], but not for women [Multivariate HR 1.03 (95% CI 0.99-1.07), p=0.130]. This increased risk was approximately equally attributable to cardiovascular disease and cancer, though somewhat more apparent for cardiovascular disease mortality in men free from diabetes, hypertension and obesity at baseline [Multivariate HR 1.10 (95% CI 1.01-1.20), p=0.023].

CONCLUSIONS

A weak increased all-cause mortality was observed in men with higher traditional Sami diet scores. However, due to the complexity in defining a "traditional Sami" diet, and the limitations of our questionnaire for this purpose, the study should be considered exploratory, a first attempt to relate a "traditional Sami" dietary pattern to health endpoints. Further investigation of cohorts with more detailed information on dietary and lifestyle items relevant for traditional Sami culture is warranted.

Facing the limit of resilience: perceptions of climate change among reindeer herding Sami in Sweden

Background

The Arctic area is a part of the globe where the increase in global temperature has had the earliest noticeable effect and indigenous peoples, including the Swedish reindeer herding Sami, are amongst the first to be affected by these changes.

Objective

To explore the experiences and perceptions of climate change among Swedish reindeer herding Sami.

Study design

In-depth interviews with 14 Swedish reindeer herding Sami were performed, with purposive sampling. The interviews focused on the herders experiences of climate change, observed consequences and thoughts about this. The interviews were analysed using content analysis.

Results

One core theme emerged from the interviews: facing the limit of resilience. Swedish reindeer-herding Sami perceive climate change as yet another stressor in their daily struggle. They have experienced severe and more rapidly shifting, unstable weather with associated changes in vegetation and alterations in the freeze–thaw cycle, all of which affect reindeer herding. The forecasts about climate change from authorities and scientists have contributed to stress and anxiety. Other societal developments have lead to decreased flexibility that obstructs adaptation. Some adaptive strategies are discordant with the traditional life of reindeer herding, and there is a fear among the Sami of being the last generation practising traditional reindeer herding.

Conclusions

The study illustrates the vulnerable situation of the reindeer herders and that climate change impact may have serious consequences for the trade and their overall way of life. Decision makers on all levels, both in Sweden and internationally, need improved insights into these complex issues to be able to make adequate decisions about adaptive climate change strategies.

What is known about the health and living conditions of the indigenous people of northern Scandinavia, the Sami?

BACKGROUND

The Sami are the indigenous ethnic population of northern Scandinavia. Their health condition is poorly known, although the knowledge has improved over the last decade.

OBJECTIVES

The aim was to review the current information on mortality, diseases, and risk factor exposure in the Swedish Sami population.

DESIGN

Health-related research on Sami cohorts published in scientific journals and anthologies was used to compare the health condition among the Sami and the majority non-Sami population. When relevant, data from the Sami populations in Swedish were compared with corresponding data from Norwegian and Finnish Sami populations.

RESULTS

Life expectancy and mortality patterns of the Sami are similar to those of the majority population. Small differences in incidences of cancer and cardiovascular diseases have been reported. The traditional Sami lifestyle seems to contain elements that reduce the risk to develop cancer and cardiovascular diseases, e.g. physical activity, diet rich in antioxidants and unsaturated fatty acids, and a strong cultural identity. Reindeer herding is an important cultural activity among the Sami and is associated with high risks for accidents. Pain in the lower back, neck, shoulders, elbows, and hands are frequent among both men and women in reindeer-herding families. For men, these symptoms are related to high exposure to terrain vehicles, particularly snowmobile, whereas for women psychosocial risk factors seem to more important, e.g. poor social support, high effort, low reward, and high economical responsibilities.

CONCLUSIONS

Although the health condition of the Sami population appears to be rather similar to that of the general Swedish population, a number of specific health problems have been identified, especially among the reindeer-herding Sami. Most of these problems have their origin in marginalization and poor knowledge of the reindeer husbandry and the Sami culture in the majority population. It is suggested that the most sustainable measure to improve the health among the reindeer-herding Sami would be to improve the conditions of the reindeer husbandry and the Sami culture.

Demography of colonisation and the ageing population: population profiles and mortality in Swedish Sápmi, 1750–1900

This paper examines population trends, age-specific death rates and causes of death for the elderly Sami and settlers during the colonisation era (between 1750 and 1900). The source material is a set of data files from the Demographic Data Base (DDB) at Umeå University that covers parish records from three different parishes. Early in the colonisation period (1750–1840) the Sami had a lower proportion of the elderly population (⩾60 years old), compared to the non-Sami and the rest of Sweden. At the end of the colonisation period (1841–1900), the proportion of elderly Sami increased and was above the proportion of elderly non-Sami and more similar to the rest of Sweden. The analysis also reveals that the differences in mortality rates among the elderly Sami and their non-Sami counterparts diminished during the entire colonisation era (1750–1900), mainly because of an increased infant mortality among the non-Sami. Rather than ethnic differences in causes of death, the results show larger differences between the parishes. The study can conclude that the Sami population's mortality declined, the health improved, and the Sami advanced more rapidly in the model of epidemiologic transition, a milestone not yet reached by other indigenous people around the world.

Health consumption in Sami-speaking municipalities with regard to cancer and radiotherapy

OBJECTIVES

The objective of this study was to document that the Sami people, constituting an ethnic minority in northern Norway, experience an equally available specialist health care service as the one offered to Norwegians in general. We aimed to use cancer and radiotherapy treatment as the instrument to clarify the situation.

STUDY DESIGN

A retrospective registry-based study.

METHODS

The 8 municipalities included in the administration area of the Sami language law were matched with a control group of 11 municipalities. Population data (numbers, sex and age) were accessed from Statistics Norway. Data on cancer incidence, prevalence and survival during the 10-year time period 1999-2008 were derived from the Cancer Registry of Norway (CRN). Five years overall survival was calculated for patients diagnosed in the time period 1999-2003. Furthermore, data on radiotherapy (RT) and treatment intention were recorded for the time period 1999-2008.

RESULTS

The Sami-speaking municipalities had a significantly lower incidence of cancer. Breast (RR 0.82 [95% CI 0.76-0.89]) and lung cancer (females RR 0.55 [95% CI 0.52-0.58], males RR 0.64 [95% CI 0.60-0.68]) were significantly less frequent. The Sami group had experienced a significant increase (Sami 54.5% [95% CI 49.2-61.7], controls 24.1% [95% CI 21.7-26.5]) in the prevalence of cancer during the last 10 years. Five years overall survival was similar among both the Sami and control groups. In both groups, 28% of cancer patients underwent radiotherapy.

CONCLUSIONS

The Sami in northern Norway had a lower risk of cancer but experienced the same use of radiotherapy in their cancer treatment as Norwegians in general.

Diet and lifestyle of the Sami of southern Lapland in the 1930s--1950s and today

OBJECTIVES

To describe the lifestyle of the Sami of southern Lapland 50 to 70 years ago in relation to the present-day Sami and non-Sami populations and, thereby, to provide a basis for future studies of culturally related determinants of health and illness.

STUDY DESIGN

A qualitative analysis, and a quantitative comparison of Sami and non-Sami groups.

METHODS

Semi-structured interviews were conducted with 20 elderly Sami concerning their parents' lifestyle and diet 50 to 70 years ago. Questionnaire data from 81 reindeer-herding Sami, 226 non-reindeer-herding Sami and 1,842 sex-, age- and geographically matched non-Sami from the population-based Västerbotten Intervention Project were analysed by non-parametric tests and partial least squares methodology.

RESULTS

Surprisingly, fatty fish may have been more important than reindeer meat for the Sami of southern Lapland in the 1930s to 1950s, and it is still consumed more frequently by reindeer-herding Sami than nonreindeer-herding Sami and non-Sami. Other dietary characteristics of the historical Sami and present-day reindeer-herding Sami were higher intakes of fat, blood and boiled coffee, and lower intakes of bread, fibre and cultivated vegetables, compared with present-day non-Sami. Physical activity was also a part of the daily life of the Sami to a greater extent in the 1930s to 1950s than today. Sami men often worked far from home, while the women were responsible for fishing, farming, gardening (which was introduced in the 1930-1950 period), as well as housework and childcare.

CONCLUSIONS

For studies investigating characteristic lifestyle elements of specific ethnic groups, the elements of greatest acknowledged cultural importance today (in this case reindeer meat) may not be of the most objective importance traditionally.

Depression and anxiety in the reindeer-herding Sami population of Sweden

OBJECTIVES

The objective of this study was to investigate symptoms and predicting factors of depression and anxiety among reindeer-herding Sami in Sweden.

STUDY DESIGN

A total of 319 reindeer-herding Sami (168 men, 151 women) were compared with urban and rural reference populations comprising 1,393 persons (662 men, 731 women).

METHODS

A cross-sectional questionnaire study on mental health, which included the Hospital Anxiety and Depression Scale (HADS). Data were analysed with regard to population, gender, age group, education and work-related stress.

RESULTS

The Sami population disclosed higher mean values for both depression and anxiety than the reference groups, with Sami men reporting the highest rates. Work-related stress was associated with anxiety and depression in the Sami group.

CONCLUSIONS

By comparing Sami men and women with reference groups of men and women living in urban and rural areas in northern Sweden, this study identified that reindeer-herding Sami men require special attention with regard to mental health problems.

Unnatural deaths in reindeer-herding Sami families in Sweden, 1961-2001

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.

Mortality patterns in geographical areas with a high vs. low Sami population density in Arctic Norway

AIMS

The aim of this study was to study mortality patterns in the population in different geographical locations in northern Norway on the basis of Sami population density.

METHODS

Mortality statistics by sex and age from 1991 to 2006 were obtained from Statistics Norway. Mortality rates, including infant mortality rates, were compared across geographical locations. The data material was divided into within and outside the the geographical areas of the Sami Development Fund (SUF) and into coastal and inland residence. Differences in mortality rates were tested by chi-quadrate tests.

RESULTS

Overall, no pronounced difference in mortality rate was found in the population between geographical areas. For men, mortality rates differed only between geographical residence in the time intervals 1991-95 and 1996-2000 for the age groups 45-59 years and 60-74 years, respectively, with outside SUF area, inland having the lowest rate. For women, there were no differences between geographical areas except for the age group 60-74 years in the time period 1991-95, where SUF coast had the highest mortality rate. For the SUF area, men had the lowest probabilities for surviving the age of 74 years and women had among the highest. No geographical difference was found in infant mortality. During the time period 1991-2006, the outside SUF area, inland had an average infant mortality rate of 1.8/1000 per year, and for SUF coast it was 6.2/1000 per year. This difference was, however, not significant (p = 0.08).

CONCLUSIONS

Overall, mortality rates were similar across geographical areas with low and with high Sami population density. However, indications of geographical differences in infant mortality should be investigated further.

Cancer among the Sami--a review on the Norwegian, Swedish and Finnish Sami populations

OBJECTIVES

The Sami are the Indigenous people of the northernmost parts of Sweden, Finland and Norway, and of the Kola Peninsula of Russia. The present review summarizes the main results from studies on cancer morbidity and mortality among the Sami and discusses these results in relation to exposure of known risk factors.

STUDY DESIGN

Literature review.

METHODS

A systematic search over the time period 1966-2008 for relevant articles was conducted on MEDLINE. Updates and recalculations of some of the results from the original data were also done.

RESULTS

Nine articles whose main focus is on cancer incidence or mortality among the Sami were identified. In all studies, the overall incidence of cancer or cancer mortality was lower among the Sami in comparison with the national populations. The differences were less striking in relation to regional reference populations, but the rates were still significantly lower for all populations of Sami, except for Swedish Sami women. Beyond the general trend of a lower cancer incidence among the Sami, there were some notable differences between the various Sami subpopulations.

CONCLUSIONS

The risk of developing and dying from cancer is low among the Sami. A life-style that includes cancer-protective factors, such as certain dietary components and physical activity, is the most likely explanation for the lower incidence of cancer among the Sami.

Stroke and acute myocardial infarction in the Swedish Sami population: incidence and mortality in relation to income and level of education

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.

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.
