An interventional study of VitDgen in Vitamin D Deficiency, sponsored by Technical University of Denmark. Completed at 2 sites in Denmark. Open to participants aged 18 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2013-08-01.
Sponsored by Technical University of Denmark · Not applicable, Interventional, and Basic science
The overall purpose of the study is to investigate whether there is a relationship between 26 different single nucleotide polymorphisms (SNPs) in the vitamin D pathway, ultraviolet B (UV-B) irradiation of the skin and vitamin D status.
The hypothesis is that vitamin D status are influated by different genetic genotypes in the vitamin D pathway.
In this study approximately 80 participants (over 18 years) are included. All the participants has previously participated in the VitmaD intervention study (NCT01184716) .
Participants will in total receive 4 times UV-B irradiation (3 SED) with two day apart each time, to stimulate vitamin D production in the skin. The participants skintype will be measured. The study starts in January 2013 and runs to the end of Marts 2013. During this winter period, it is in Denmark not possible to produce vitamin D in the skin through sunlight exposure.
784 studies on the registry are indexed under Vitamin D Deficiency; 61 are open to participants now.
This study's enrollment of 102 is above the median of 77 across 574 interventional studies indexed under Vitamin D Deficiency.
