Objectives. To gain knowledge on toxic elements in semi-domesticated reindeer and their distribution in meat, liver, tallow and bone marrow. The correlations between concentrations in meat and liver, as well as the use of the latter as an indicator for toxic elements in meat, were also investigated. Study design. Cross-sectional study on population of semi-domesticated reindeer from 2 northern ...

Aim We aimed to investigate the relationship between pre- and post-diagnostic 25-hydroxyvitamin D (25(OH)D) concentrations and type 2 diabetes (T2DM) over a period of 30 years in individuals who developed T2DM compared to healthy controls.<p> <p>Methods This case–control study included 254 participants with blood samples collected at fve diferent time-points (T1–T5) between 1986 and 2016. Of the ...

The diet of the Indigenous Sami people has become more Westernized. The lack of population-based data on nutrient intake and nutritional adequacy, in combination with a high prevalence of obesity/metabolic syndrome among Sami, was the rationale behind the present study. We hypothesized that differences in nutrient intake between Sami and non-Sami populations may still exist but that these differences ...

<i>Objective</i>: This study aims at presenting the feasibility of using the public oral health clinics in indigenous Sámi communities, as arena for a comprehensive data collection for population-based epidemiological oral health research among adults (age, 18–75 years) in a multi-ethnic setting.<p> <p><i>Material and methods</i>: The study design was cross-sectional. The data collection was ...

<i>Background</i> - The aim of the study was to describe prevalence, severity and distribution of periodontal disease as well as associated risk factors in an indigenous Sámi population in Northern Norway, and to investigate differences between the indigenous Sámi and the non-Sámi population.<p><p> <i>Methods</i> - This cross-sectional study included data from the Dental Health in the North study ...

Background/Objectives: Vitamin D deficiency has been associated with increased risk of developing several diseases, but much is unknown about the molecular effects involved. Gene expression technology is increasingly being used to elucidate molecular mechanisms related to nutritional factors, and in this study of free-living, middle-aged Norwegian women, we aimed at identifying gene expression ...

According to the World Cancer Research Fund International, vitamin D might decrease the risk of colorectal cancer (CRC). However, less is known about the association with cancers in different subsites of the colon and in the rectum. The aim of this study was to examine associations between pre-diagnostic intake of vitamin D and risk of CRC by anatomical subsites. Data from 95 416 participants in the ...

In post-war Norway, only the 1970 national census has recorded ethnicity information about the indigenous Sámi, however restricted to those living in selected areas in the north. In this study, we combine replies about Sámi ethnicity given by the same individuals in Norway’s 1970 census and in the population-based SAMINOR study in 2003–04, to compare self-reported Sámi ethnicity at two points in ...

Diets rich in omega-3 fatty acids and low in saturated fat were found beneficially associated with blood lipids and cardio-vascular health. Lean reindeer meet and local cold water white-fish species high in omega-3 are among the main sources of nutrients in the rural area of the Nenets Autonomous Okrug (NAO) in Russia and are not normally consumed by the urban population from the same region. The ...

<p><i>Objective</i>: To examine timing of eating across ten European countries.</p> <p><i>Design</i>: Cross-sectional analysis of the European Prospective Investigation into Cancer and Nutrition (EPIC) calibration study using standardized 24 h diet recalls collected during 1995–2000. Eleven predefined food consumption occasions were assessed during the recall interview. We present time of consumption ...
