However, data indicating changes of specific health complaints are limited. This study ...
    • Hvordan samsvarer verdier for jodinntak målt ved ulike metoder? Resultater fra unge kvinner i MISA 2-undersøkelsen 

      Renå, Caroline Spets (Mastergradsoppgave; Master thesis, 2024-05-15)
      Introduksjon: Utilstrekkelig jodinntak er et folkehelseproblem i flere land. Mange land i Europa og Norden har individer som er i risiko for mild til moderat jodmangel. Særlig fertile kvinner, gravide og ammende er i risiko. Jod er et sporstoff som er essensielt for thyreoideahormonene trijodtyrotyronin og tyroksin. Hormonene er involvert i reguleringen av metabolismen og er viktig for normal utvikling ...
    • Intake of Fat and the Risk of Epithelial Ovarian Cancer in the Norwegian Women and Cancer Study

The aim was to study the possible associations between the intake of total fat, trans fatty acids, polyunsaturated fatty acids, monounsaturated fatty acids, saturated fatty acids, cholesterol ...
    • An Investigation into the Effects of Chronic High Fructose Consumption on Liver Histology, Triglyceride Content and Gene Expression in Male Sprague-Dawley Rats 

      Fredriksen, John Martin Ming (Mastergradsoppgave; Master thesis, 2024-05-14)
      Background: Chronic high fructose intake is associated with the metabolic syndrome (MetS) and metabolic-dysfunction associated fatty liver disease (MAFLD). Fructose metabolised in the liver is not subject to the same strict regulation as glucose, and high fructose intake can therefore increase lipid production and storage, leading to detrimental metabolic changes. Fructose may also induce hypertension ...

The three important contaminant groups—radioactive substances, heavy metals, and persistent organic pollutants (POPs)—were measured in food samples such as berries, mushrooms, fish, ...
    • Vitamin D and periodontitis; is there an association between vitamin D deficiency and periodontitis severity? A cross-sectional study 

      Lindholm, Fanny (Mastergradsoppgave; Master thesis, 2022-06-06)
      Background: Periodontitis is an oral disease which is highly prevalent in the adult population worldwide. Periodontitis is characterized by an excessive inflammatory reaction which leads to the destruction of supportive periodontal tissues and potentially tooth loss in the more severe stages of disease. Known risk factors for periodontitis include conditions and lifestyle factors which increase the ...
    • Description of disordered eating among female athletes in Norway 

      Vedenpää, Mimmi Meiju Susanna (Master thesis; Mastergradsoppgave, 2023-06-01)
      Disordered eating behavior (DEB) is more prevalent among female athletes compared to both male athletes and non-athlete women. This behavior can significantly compromise both the performance and overall health of athlete. However, it has been almost two decades since previous research reported DEB prevalence in the athletic Norwegian population, making an update on the subject necessary. This study ...

      Lund, Åse Karlsen (Master thesis; Mastergradsoppgave, 2022-05-31)
      Background: Physical activity (PA) reduces the risk of mental health problems. However, there is limited knowledge of the influence of PA on psychological distress (PD) in a Sami population. Aim: to investigate the association between PA levels and PD among a Sami and non-Sami population in Norway, and if the association differed between gender in both ethnic groups. Materials/methods: Data from ...

Arctic populations present high contaminant concentrations compared to ...
    • Adult Attained Height and Breast Cancer Incidence (NOWAC) 

      Wallumrød, Henrik Hansen (Master thesis; Mastergradsoppgave, 2023-05-31)
      <p>Introduction: Adult attained height has been associated with breast cancer incidence consistently in the literature. The inclusion of covariates to adjust the regression models is widely used as a tool for controlling for error in models and reducing bias. However, several epidemiological studies regarding height have not accounted for confounding variables in their analysis. <p>Material and ...

      Skoglund, Jane (Master thesis; Mastergradsoppgave, 2022-05-30)
      Abstract Introduction: Diabetes mellitus is an increasingly public health concern, causing increased mortality, morbidity and healthcare costs globally. Global increase in overweight and obesity, high calorie diets, sedentary lifestyle, smoking habits and aging population are the main drivers for this epidemic. Social inequalities reveal systematic differences in health and disease. Social inequalities ...

      Trace elements are important for human health but may exert toxic or adverse effects. Mechanisms of uptake, distribution, metabolism, and excretion are partly under genetic control but have not yet been extensively mapped. Here we report a comprehensive multi-element genome-wide association study of 57 essential and non-essential trace elements. We perform genome-wide association meta-analyses of ...
    • The association between emotional violence in childhood and the utilization of somatic and psychiatric specialist healthcare in adulthood among Sami and non-Sami population: The SAMINOR 2 questionnaire study 

      Osman, Farhiyo Ahmed (Mastergradsoppgave; Master thesis, 2022-06-03)
      Abstract Background: Emotional violence in childhood (EVC) is the most common type of violence in childhood. Due to its subtle and nonverbal nature, researchers have paid less attention to EVC than physical and sexual childhood violence. EVC may be just as detrimental to the developing brain of a child as other forms of childhood violence. Some studies has found that it increases the odds of ...

    • Association between participation in organized activity and loneliness among adolescents in Tromsø municipality - A cross sectional study 

      Larsen, Mathias (Mastergradsoppgave; Master thesis, 2023-05-31)
      Abstract Background Loneliness is a common subjective feeling. We might feel lonely, but still engage and interact in social groups, and we can be alone and live happily. Participation in organized activity might reduce mental health challenges through social mechanisms, with the opportunity of developing life skills and social relationships. To my knowledge, no previous studies have investigated ...
    • Nutrient Intake and Retinopathy: The Tromsø Study 

      Ojei, Nancy Chukwuedum (Mastergradsoppgave; Master thesis, 2023-05-31)
      Abstract Introduction: Retinopathy is a retinal disorder characterized by microvascular complications due to ocular or systemic conditions. The non-invasive visualization of retinal blood vessels provides a way to study the early structural and pathological changes in the circulatory system. Hence retinopathies can be used to monitor risk factors for cardiovascular diseases. Several studies have ...
    • The cost of saying no: general practitioners’ gatekeeping role in sickness absence certification 

      Hoff, Eivor Hovde; Kraft, Kristian Bandlien; Moe, Cathrine Fredriksen; Nylenna, Magne; Østby, Kristian Amundsen; Mykletun, Arnstein (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-12)
      Background General practitioners (GPs) have an important gatekeeping role in the Norwegian sickness insurance system. This role includes limiting access to paid sick leave when this is not justified according to sick leave criteria. 85% of GPs in Norway operate within a fee-for-service system that incentivises short consultations and high service provision. In this qualitative study, we explore ...
    • The Association between the Energy-adjusted Dietary Inflammatory Index and the Risk of Colorectal Cancer in The Norwegian Women and Cancer Study (NOWAC) 

      Berg, Anna Emilie Vinje (Mastergradsoppgave; Master thesis, 2023-05-15)
      Background: Colorectal cancer (CRC) is one of the most common cancer types and a leading cause of cancer death worldwide. Norwegian women had the highest incidence rate in 2020 compared to women in other countries. Existing evidence suggests that the dietary inflammatory potential is associated with the risk of CRC and that the risk may vary by anatomical subsite. However, the findings are inconsistent ...
