Abstract
Little published data has assessed the association between socio-economic deprivation and 25- hydroxyvitamin D (25(OH)D) concentration. One study found low socio-economic status predicted vitamin D deficiency(Reference Leger-Guist'hau, Domingues-Faria and Miolanne1), but another did not(Reference Ersoy, Kizilay and Yilmaz2).
Our objective was to assess the relationship between 25(OH)D and Townsend Deprivation Index (TDI) in a large sample, using data from the UK Biobank Cohort, which has data on 502,000 individuals (baseline 2006–2010, aged 40 years or over). Blood draws, for measurement of serum 25(OH)D by the DiaSorin Liaison XL assay, were spread across the year with each participant sampled once. The UK Biobank holds ethical approval from UK North West Multi-Centre Research Ethics Committee (11/NW/0382).
