    • The association between sugar sweetened or carbonated beverages and bone mineral density in adolescents taking part in the Fit Futures Study. 

      Rafoss, Mari (Master thesis; Mastergradsoppgave, 2017-12-31)
      In the prevention strategies for osteoporosis attention has been directed towards the acquisition of peak bone mass and early life experiences during the adolescent growth period. High consumption of soft drinks during adolescence is believed to influence bone mineral accrual and increase fracture risk later in life. The aim of this study is to investigate if moderate or high consumption of sugar ...

    • Association between Variants in the OCA2-HERC2 Region and Blue Eye Colour in HERC2 rs12913832 AA and AG Individuals 

      Salvo, Nina Mjølsnes; Andersen, Jeppe Dyrberg; Janssen, Kirstin; Meyer, Olivia Luxford; Berg, Thomas; Børsting, Claus; Olsen, Gunn-Hege (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-11)
      The OCA2-HERC2 region is strongly associated with human pigmentation, especially eye colour. The HERC2 SNP rs12913832 is currently the best-known predictor for blue and brown eye colour. However, in a previous study we found that 43 of 166 Norwegians with the brown eye colour genotype rs12913832:AA or AG, did not have the expected brown eye colour. In this study, we carried out massively parallel ...

    • The association between visceral fat and lifestyle factors in an adult population: The Tromsø Study 2015-2016. 

      Kakuruwo, Geraldine Wadzanai (Mastergradsoppgave; Master thesis, 2023-05-31)
      Introduction: Visceral fat (VAT) is the most metabolically, harmful type of body fat. It is in the abdomen and it surrounds organs like kidneys, pancreas and liver and is associated with higher risk for morbidity. VAT is accurately measured by dual-energy X-ray absorptiometry (DXA). Due to the imbalance between energy intake and expenditure, excessive VAT accumulation occurs; therefore, a healthy ...
