7750.00002. Iron status and prevalence of hereditary haemochromatosis in a multiethnic population in Northern Norway.

Prosjektleder/Principal investigator: ANN RAGNHILD BRODERSTAD.

Prosjektsammendrag/Project summary: Hereditary haemochromatosis (HH) has an autosomal recessive inheritance.  The C282Y homozygosity is the most common genetic mutation in persons of Northern European descent. A screen of two multiethnic populations in Northern Norway was performed to investigate whether the prevalence of hereditary haemochromatosis was consistent with previous results in Northern Europe. Material and Methods: Participants in two population-based studies in Northern Norway were analyzed for serum ferritin (s-ferritin) and transferrin saturation. Participants with transferrin saturation or s-ferritin above the reference limits in two separate blood samples were tested for three different HFE mutations, namely C282Y, H63D and S65. Results: The estimated prevalence of the C282Y/C282Y mutation in the two municipalities studied was lower than in comparable studies in Norway. The prevalence was lowest in the Sør-Varanger population (men 0.19% and women 0.22%), which also had the highest proportion of individuals with Sami and Kven affiliation. In Tromsø the prevalence was consistent with previous results in Norway. Conclusions: The prevalence of hereditary haemochromatosis is lower in multiethnic populations in Northern Norway than in previous studies from other parts of Norway.

8010.00013. Living conditions and health among the Sami and other indigenous peoples in the Arctic.

Prosjektleder/Principal investigator: ANN RAGNHILD BRODERSTAD.

Prosjektsammendrag/Project summary: To artikler skal skrives:

1) Kardiovaskulær sykdom (CVD) er den vanligste dødsårsaken i Norge. I tillegg til faren for tidlig død, kan forekomsten av koronarsykdom og hjerneslag ha betydelige negative konsekvenser for pasientens helse og livsutfoldelse. En rekke risikofaktorer som tobakksbruk, alkoholforbruk, fedme, høyt blodtrykk og høyt totalkolesterol er knyttet til forekomst av CVD. Tidligere forskning viser også at risiko for utvikling av CVD og hypertensjon øker ved akkulturasjon. Undertegnede ønsker å undersøke en slik problemstilling i en samisk kontekst og da fokusere på marginalisering (den mest helseutsatte tilstanden av akkulturasjon).

2) Psykisk helse og akkulturasjon er et voksende fagfelt, men lite forskning er gjort i denne sammenheng i den samiske befolkning. Jeg ønsker å se på effekten av marginalisering på HSCL-10-scoren i den samiske befolkning.

8010.00050. Validering av selvrapportert hjerteinfarkt (MI) og hjerneslag/hjerneblødning, og oppfølgingsstudie av hjerte- og karsykdom og -død i SAMINOR 1.

Prosjektleder/Principal investigator: BENT-MARTIN ELIASSEN.

Prosjektsammendrag/Project summary: Questionnaires are commonly used to collect data on the prevalence and incidence of cardiovascular disease (CVD). In Norway, however, very little research has been conducted concerning the validity of these questionnaires. Even less knowledge is available on the validity of these variables in the multiethnic population of northern Norway. Thus, in this study we shall measure the validity of self-reported myocardial infarction and stroke in the Sami and non-Sami populations of northern Norway. Data from SAMINOR 1 and CVDNOR shall be used.

Furthermore, we propose to conduct a follow-up study on CVD and death from CVD by using data from SAMINOR 1, CVDNOR and the Causes of Death Registry. Herein we shall explore if there are differences in the risk of CVD and CVD death between Sami and non-Sami. The follow-up time is  5 to 6 years. The endpoint is vast and includes a number of CVDs and cardiovascular related diseases.

8010.00062. Use of traditional medicine (TM) in the SAMINOR 1 study.

Prosjektleder/Principal investigator: AGNETE KRISTOFFERSEN.

Prosjektsammendrag/Project summary: Traditional medicine (TM) or "folk medicine" is knowledge, beliefes and traditions oncerning sickness, disease prevention, treatments and cures that are associated with a particular ethnic group. In northern Norway, the traditional folk medicine is influenced by the Sami folk medicine, reflecting the Sami understanding of nature, hamunity and life, shaped by both Christiany and traditional Sami nature worship. Examples are blood-stemming, laying on hands and "reading", the reciting of special verses known only to the healers. Use of traditional healing in northern Norway is presumed to be widely used, in particular in areas with inhabitants of Sami ethnicity. Knowledge about traditional medicine use in Sami areas is important to secure for a culture sensitive health care in these regions. The overall purpose of this proposal is therefore to present the prevalence and associations for TM use in areas with Sami and Norwegian population and examining the influence of ethnicity, geography, gender, age, education, household income, religiosity and self-reported health.

8030.00083. Etnisk diskriminering i relasjon til fysisk og mental helse i samiske bosetningsområder.

Prosjektleder/Principal investigator: KETIL LENERT HANSEN.

Prosjektsammendrag/Project summary: Self-reported ethnic discrimination has been associated to a range of health outcomes. This study build on previous work in Norway to further investigates the prevalence of self-reported experience of ethnic discrimination and bullying among indigenous Sami population, and associations with multiple health measures. In last years, evidence indicating discrimination as an important determinant of health. The majority of ethnic discrimination research has been undertaken in adult populations. Among adult population, reported ethnic discrimination is higher among indigenous and minority populations. In Norway, indigenous Sami adult people, experience significant more discrimination than ethnic Norwegians, and experiencing ethnic discrimination was associated with adverse self-reported overall health status and psychological stress (anxiety and depression symptoms). The overall goal of this project is to continue the research on discrimination and health from the first SAMINOR study and study what other factors associated with perceived discrimination and negative health consequences.

8030.00091. Physical activity, cardiovascular risk factors and mortality in ethnic groups in Finnmark County, Norway.

Prosjektleder/Principal investigator: RUNE HERMANSEN.

Prosjektsammendrag/Project summary: Finnmark county has had the highest coronary and total mortality in Norway. Reports have shown that the cholesterol level was higher than national average and the proportion smokers was the highest in Norway. Samis were more physical active and had lower heart rate than Norse in data from 1987. The lower heart rate among Samis, could be a result of a higher aerob activity at work and better fitness. We want to examine if these findings could give health benefits on hard end-points as cardiovascular and all-cause mortality.

8030.00107. Konsekvenser av lokale utslipp på nivåer av PFOS i mennesker – Harstad/Narvik lufthavn pilotstudie.

Prosjektleder/Principal investigator: SOLRUNN HANSEN.

Prosjektsammendrag/Project summary: Det er nettopp påvist svært høye nivåer av miljøgiften PFOS i to vann og i grunnvannet rundt Harstad/Narvik lufthavn etter lang tids bruk av stoffet på flyplassen. Nivåene i vann og fisk er over anbefalte grenseverdier, og tiltak og videre undersøkelser anbefales. Det skal være populært å fiske i disse vannene. Samtidig som dette ble klart, ble innsamlingen av blodprøver, kliniske og antropometriske data inkludert kosthold fra 1050 deltagere i «Helse og levekårsundersøkelsen i områder med samisk og norsk bosetting» SAMINOR 2 avsluttet i Skånland og Evenes kommune. Ved å kontakte deltagere som spiser innlandsfisk på nytt kan vi raskt få oversikt over hvor mange som bruker fisk fra berørt vassdrag. Analyse av 50 blodprøver fra de som spiser denne fisken vil gi oss en klar indikasjon på nivåer i berørt befolkning. Dette vil raskt kunne gi oss en indikasjon på andelen av befolkningen som er berørt og vil danne grunnlaget for en eventuell større studie på mulige effekter av dette.

8030.00108. Aspects of self-reported oral health among indigenous Sami and non-Sami adults in Northern- and Mid-Norway. A cross-sectional study.

Prosjektleder/Principal investigator: TORDIS TROVIK.

Prosjektsammendrag/Project summary: The last 30 years have seen a significant improvement in dental health. Studies shows fewer tooth extractions; the number of natural teeth increases and the number of teeth with treatment increases. These changes have occurred in parallel with an increased availability of dentists. In the population >21 years, 3/4 reports that their dental health is good, while 1/10 does not visit a dentist, despite that they report they have a need for dental care. The overall positive trend is not equally distributed in the country. Studies have shown that social inequalities in health is an important underlying cause of disease development. On the other hand, a national cross-sectional study showed a relatively weak correlation between social status and oral health status. Finnmark had the lowest percentages of children/adolescents with no caries-experience and dental health and use of dental health services is particularly poor in the areas with large Sami populations. Additionally, knowledge on dental health status among adults in Finnmark is rare. Information in this study did not include ethnicity. The overall aim of the project is to study aspects of self-reported oral health in the adult population in selected municipalities in Northern and Central Norway with large Sami populations. Further, to analyze dental health behavior, experience and satisfaction with dental health and dental health services related to gender, age and risk factors for dental diseases. The study is based on Saminor-2-data (2012); n=11600 participated; the response rate was 27%, and 34% participants reported Sami affiliation.

Prosjektleder/Principal investigator: ANN RAGNHILD BRODERSTAD.

Prosjektsammendrag/Project summary: The SAMINOR survey is a population-based study on health and living conditions in areas with both Sami and Norwegian settlements.

The first SAMINOR study was conducted in 2003-2004. In 2012 the Centre for Sami Health Research initiated a follow up survey, SAMINOR 2. The data collection was done in two parts. Part 1, a questionnaire study in the same areas where SAMINOR1 was carried out, was conducted in 2012. It included 11 600 participants between 18 – 69 years. The clinical part (part 2) was done in the period September 2012 to June 2014, where all inhabitants aged 40-79 years in 10 municipalities in Northern Norway were invited. In total, 6004 persons visited the research station, a participation rate of 48 %. In this clinical part, focus have been addressed diabetes, metabolic syndrome and cardiovascular diseases, but also enclose contaminants, dental health and sleeping behaviors. Data consist of a self-administered questionnaire, blood sampling and physical examination like height and weight, abdominal/hip circumference and blood pressure.

The aim of this particular studentproject is to describe the distribution of Hb and iron status among Sami and non-Sami population in Northern Norway.

8030.00110. Klassifisering av diabetes mellitus i SAMINOR 1.

Prosjektleder/Principal investigator: ANN RAGNHILD BRODERSTAD.

Prosjektsammendrag/Project summary: Diabetes mellitus is a part of the SAMINOR study performed among the rural population in Northern Norway and the Sami population in particular. The survey is a public health investigation conducted within the epidemiological methodological framework with both cross-sectional and longitudinal designs. Diabetes mellitus is one of the major clinical parts of the SAMINOR study. This study demonstrated a high prevalence of overweight and obesity. Information about self-reported diabetes mellitus was available, in addition to body mass index, blood pressure, and blood lipids. Obesity is a strong indicator for developing diabetes mellitus. In the SAMINOR study diabetes mellitus was identified using a questionnaire, in addition to measured random plasma glucose = 11.1 mmol/L in participants whom did not report diabetes mellitus.

Prosjektleder/Principal investigator: ANNE SILVIKEN.

Prosjektsammendrag/Project summary: Several studies have documented that suicide is a serious public health problem in the Arctic region, both in the general population and especially among several indigenous people. Suicide attempts can be considered as a part of the suicidal process, but may in many respects be another phenomena. However, suicide attempters represent a risk group. About 10 % of suicide attempters are estimated to die by suicide in a lifetime perspective. There is a strong association between self-destructive behavior such as suicide attempts and substance use/abuse. Both suicide attempts and substance use/abuse can function as negative coping strategies in the struggle to live with mental health problems and/or to regulate negative affects. In addition, alcohol, both substance use and abuse disorder, is well-known risk factors for suicidal behaviour, and can both function as an proximal and distal risk factor. Method: This study is using data from a population-based study on health and living conditions in areas with mixed Sami and Norwegian settlements – the SAMINOR 2 questionnaire study.

8030.00128. The prevalence of psychotropic medication use among Sami and non-Sami in Northern Norway.

Prosjektleder/Principal investigator: ANNE SILVIKEN.

Prosjektsammendrag/Project summary: Mental health problems such as internalizing symptoms (anxiety and depression) are common phenomena in the general population and has been referred to as a new public health disease. Knowledge of disease burden related to internalizing symptoms such as anxiety and depressive symptoms as well as use psychotropic medication in the Sami adult population is limited. Several studies have reported that indigenous people in general use public help services less frequent than the majority population, but a similar pattern is not found among both adolescents and adult Sami in Norway. Bals and colleges (2010) found no ethnic differences in self-reported use of help services among Sami and non-Sami adolescents during 2003/04, and a master thesis from the SAMINOR 1 study (2003) showed that adult Sami reported visiting their regular GP just as often as the non-Sami (Hansen, 2015b). In a register based study on use of health care, expenditure rates were found to be similar in municipalities with a high number of Sami residents compared to other rural municipalities (Gaski, Melhus, Deraas & Førde, 2011). Population based health research is essential for understanding health situation and living conditions in the Sami population. Scientific-based knowledge on topics such as mental health and use of medication is important in prevention and implementation of means to improve the health services in multi-ethnic areas in North Norway.

8110.00003. Kosthold og ernæring i den norske samiske befolkningen – SAMINOR2 klinisk del.
Prosjektleder/Principal investigator: MAGRITT BRUSTAD.

Prosjektsammendrag/Project summary: Based on recent scientific evidence, dietary risk factors account largely for the burden of cancer, cardiovascular diseases and type 2 diabetes in the Norwegian population. In general, there is a lack of population-based dietary studies in Norway. Recently, there has been a growing interest in vitamin D status, its optimal level and food sources. There are still knowledge gaps and inconsistencies in this research area. To the best of our knowledge, no large-scale mixed-gender studies on food / nutrient intakes and vitamin D status in relation to ethnicity, which cover an extensive geographical area of the northern part of Norway, have been conducted. The postdoctoral project “Diet and nutrition in the Norwegian Sami population – the SAMINOR 2 clinical study” is a sub-project of the SAMINOR 2 clinical study. Data were collected in 10 selected municipalities in the traditionally Sami core areas of Northern Norway by the Centre for Sami Health Research, UiT The Arctic University of Norway in 2012–2014. Thus, a high proportion of the participants in this study reported to have a Sami background. In total, 4876 adults in the age group of 40-69 attended questionnaire survey (included lifestyle and food frequency questionnaire), physical examination and blood sampling. The proposal of this postdoctoral project is to generate knowledge about food / nutrient intakes and vitamin D status in a multi-ethnic population of Northern Norway, with special focus on the Sami group and traditional foods.

Dette skyldes dels at det ikke utarbeides oppdaterte fortegnelser over samebefolkningens utbredelse og sammensetning. Geografiske avgrensninger og demografiske fortegnelser er sentrale rammeverk for studier hvor målet er å vinne kunnskap om hele eller deler av en gitt befolkningsgruppe. I mangel av slike rammeverk må samisk helse- og levekårsforskning baseres på alternative eller tilpassede datakilder. Disse kildene må ta høyde for at etnisitet i seg selv er et mangefasettert og dynamisk fenomen.

Hensikt: Bidra til økt kunnskap om hvordan samebefolkningens levekår kan måles.

Delmål:

-Dokumentere endringer i definisjoner av samiske bosettingsområder i Norge.

-Dokumentere endringer i selvrapportert samisk etnisitet over tid (etter 1970).

-Studere i hvilken grad det kan påvises sammenhenger mellom levekårsvariasjoner og endringer i selvrapportert samisk etnisitet over tid.

-Sette situasjonen med manglende samiske demografiske data inn i en større sammenheng ved å relatere den til internasjonale diskurser om etnisitetsdata.

Materiale og metoder

-SamiNor 2003 - en helse- og levekårsundersøkelse i områder med samisk og norsk bosetting.

-Folke- og boligtellingen 1970

-Kobling og statistiske analyser av data fra SamiNor 2003 og FoB 1970.

-Analyser av dokumentasjonsgrunnlag for FoB 1970 og for samisk geografisk statistikk.

-Analyser av antall innmeldte i Sametingets valgmanntall over tid. -Utvalg og litteraturgjennomgang av tekster om innhenting og bruk av etnisitetsdata i helse- og levekårsstudier internasjonalt, med vekt på urfolks situasjoner.

8290.00046. Health care utilization in Sami areas in Norway.

Prosjektleder/Principal investigatorBENT-MARTIN ELIASSEN.

Prosjektsammendrag/Project summary: Previous studies have reported an under-use of health care services and less satisfaction with the general practitioner (GP) service among Sami-speaking users compared to the majority.

Recent results from register-based studies have found no differences in health care expenditure or GP referral rates between municipalities belonging to the administrative area of the Sami language and other municipalities. Updated and individual data is however needed to determine whether there are ethnic differences in health care utilisation in areas with both Sami and non-Sami populations in Norway.

Medikamentbruk blant befolkningen bosatt i de norske samiske kjerneområdene. (Drug use among the population in the Norwegian Sámi areas.)

Prosjektleder/Principal investigator: EILIV LUND.

Prosjektsammendrag/Project summary: Hovedmålet med prosjektet er å beskrive medikamentbruk og etnisitet i befolkningen i de samiske kjerneområdene i Norge. Vi vil i første omgang se om det er forkjeller i medikamentbruk i de ulike etniske gruppene i den samiske helseundersøkelsen. I hvilken grad vil sosio-økonomiske og geografiske forhold spille inn. Vi vil også undersøke om det er noen sammenheng mellom bruk av medikamenter og bruk av håndspålegging. Kan man for eksempel se mindre bruk av smertestillende og andre medikamenter blant folk som benytter seg av håndspålegging?

Pasienttilfredshet blant den samisktalende befolkning.

Prosjektleder/Principal investigator: EILIV LUND.

Prosjektsammendrag/Project summary: Regjeringens handlingsplan for helse og sosialtjenester til den samiske befolkningen i Norge 2002-2005 har som mål at den samiske befolkningen skal ha et like godt møte med helse og sosialtjenesten som den øvrige befolkningen. I 1992 ble det vedtatt en lov om samisk språk. I følge denne loven skal den som ønsker å bruke samisk for å ivareta egne interesser overfor lokale og regionale offentlige helse- og sosialinstitusjoner i forvaltningsområdet, ha rett til å bli betjent på samisk (1). Området der denne loven praktiseres kalles forvaltningsområdet for samisk språklov.

Plan for helse og sosialtjenester; NOU 1995, påpeker at den samiske befolkningen opplever store problemer i møte med helse og sosialtjenestene. Språklige barrierer vanskeliggjør både utredning, diagnostisering, behandling, pleie, omsorg og brukerinformasjon. Manglende kunnskap om samisk kultur blant helse og sosialpersonell resulterer ofte i feilslått oppfølgning av samiske brukere (2).

Det er gjort lite forskning og utredningsarbeid rundt disse forholdene, men det foreligger en del mindre kvalitative og kvantitative brukerundersøkelser fra områder med samisk befolkning. Mesteparten av kunnskapen om denne problemstillingen kommer fra praktiske erfaringer som helse og sosialarbeidere i samiske områder har gjort seg (1).

Ved å sammenlikne samisk- og norsktalende brukere av helsetjenestene, ønsket vi å studere om det forekom forskjeller i deres tilfredshet med de kommunale legetjenestene.

Kostvaner og dets prediktorer i befolkningen bosatt i de norske samiske kjerneområdene. (Dietary pattern and its predictors in the population in the Norwegian Sámi areas).

Prosjektleder/Principal investigatorMAGRITT BRUSTAD.

Prosjektsammendrag/Project summary: Det er gjort lite forskning på kostholdet i de samiske kjerneområdene i Norge i forhold til etnisitet. Hovedmålet med prosjektet er å beskrive kostvaner og etnisitet i befolkningen bosatt i de samiske kjerneområdene i Norge i forhold til ulike demografiske-, sosiale- og livsstilsvariable. Analysene vil benytte etnisitet som stratifiseringsfaktor. Dataene vil kunne brukes til å beskrive kostmønster og kostvaner og endring av disse over tid i forhold til en rekke bakgrunnsvariable. Dette vil kunne utgjøre et viktig bidrag til den manglende eræringsepidemiologiske kunnskapen fra de samiske kjerneområdene i Norge.

Etniske forskjeller i risiko for kroniske muskel- og skjelettsmerter blant en befolkning i Nord-Norge: SAMINOR-undersøkelsen.

Prosjektleder/Principal investigator: KETIL LENERT HANSEN.

Prosjektsammendrag/Project summary: Jeg vil i denne studien fokusere på muskelskjelettsmerter blant utøvere av primærnæringer. Tidligere studier viser at disse er mer utsatt for muskelskjelettsmerter enn personer i andre yrker. Finnes det etniske forskjeller i rapporteringen om muskel- og leddsmerter og bruk av smertestillende blant utøvere av primærnæringer og kan arbeidsulykker være en årsak til muskel- og skjelettsmerter?

Laktoseintoleranse blant den samiske, kvenske og ikke-samiske befolkningen i SAMINOR-materialet

Prosjektleder/Principal investigator: KNUT JOHNSEN.

Prosjektsammendrag/Project summary: Det er tidligere publisert høy forekomst av laktoseintoleranse blant samer i Finland (T Sahi), (prevalens fra 25-60%). I Sverige har 9% av befolkningen laktoseintoleranse og samme tall for Finland er mellom 14-23% med en sør-nord gradient. Tilsvarende undersøkelser blant samer er ikke gjort i Norge, men den generelle prevalensen for hele befolkningen er rundt 10%.

SAMINOR undersøkelsen har noen spørsmål knyttet til melkeinntak (har du hatt plager i mage/tarm etter inntak av melk?). Preanalyser viser at det er en etnisk forskjell mellom gruppene i dette materialet.

Laktoseintoleranse skyldes nedsatt aktivitet av enzymet laktase i tynntarmslimhinnen. Laktose toleranse er dominant arvelig (recessivt autosomal). Det er funnet punktmutasjon på genet som koder for enzymet laktase, som forklarer hvor enkelte folkegrupper (nord-europeere) beholder latase-aktiviteten hele livet igjennom.

Prosjektets overordnede problemstilling er å finne prevalensen av melkeintoleranse blant befolkningen i SAMINOR-materialet.

Experiences of ethnic discrimination in Sami settlement areas in Norway and associations with multiple health domains

Prosjektleder/Principal investigator: KETIL LENERT HANSEN.

Prosjektbeskrivelse/Project summary: Selv-rapportert diskriminering har blitt knyttet til en rekke helse utfall i forskjellige land og blant ulike etniske grupper. I mitt doktorgradsarbeid har jeg vist at det er en assosiasjon mellom etnisk diskriminering og selv-rapportert helse og psykisk helse (i form av stress og depresjonssymptomer).

I denne studien ønsker jeg å gå videre med denne forskningen, og studere hvilken andre risikofaktorer (i tillegg til helsemål/helseatferd) som kan være assosiert med selv-rapportert diskriminering.

Hvordan diskriminering påvirker somatisk- og psykisk helse er knyttet til et komplekst samspill mellom sosiale, kulturelle, psykologiske og biologiske faktorer. I denne studien ønsker vi å undersøke assosiasjonen mellom etnisk diskriminering/mobbing og ulike helse utfall/risiko faktorer.
