Objective To investigate serum 25-hydroxyvitamin D (S-25(OH)D) concentration in a multi-ethnic population of northern Norway and determine predictors of S-25(OH)D, including Sami ethnicity. Design Cross-sectional data from the second survey of the Population-based Study on Health and Living Conditions in Regions with Sami and Norwegian Populations (the SAMINOR 2 Clinical Survey, 2012-2014). S-25(OH)D was measured by the IDS-iSYS 25-Hydroxy Vitamin D & x2e2; assay. Daily dietary intake was assessed using an FFQ. BMI was calculated using weight and height measurements. Setting Ten municipalities of northern Norway (latitude 68 degrees-70 degrees N). Participants Males (n 2041) and females (n 2424) aged 40-69 years. Results Mean S-25(OH)D in the study sample was 64 center dot 0 nmol/l and median vitamin D intake was 10 center dot 3 mu g/d. The prevalence of S-25(OH)D Peer reviewed
