  5. 4. Boning up on Vitamin D : Observational Studies on Bone and Health

    Författare :Greta Snellman; Karl Michaëlsson; Haakon Meyer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vitamin D; fracture; BMD; assays; genes; mortality; cohort studies; Orthopaedics; Ortopedi;

    Sammanfattning : The primary function of vitamin D in humans is to maintain sufficient circulating calcium concentrations. Low vitamin D levels could result in excessive calcium resorption from bone. Vitamin deficiency may therefore decrease bone mineral density (BMD), resulting in an increased risk of fracture. LÄS MER
