"Adolescents within tier 4 adolescent mental health services may be at higher risk of vitamin D deficiency and so assessment of vitamin D levels should be considered as part of a standard physical health review for this group of young people."So said the results reported by Neil Stewart & Simon Lewis [1] (open-access) who surveyed blood test results of patients admitted to a tier 4 psychiatric unit for vitamin D levels. Such a study was conducted on the basis that "it is plausible that vitamin D and/or vitamin D deficiency have a role in the pathogenesis of mental illness." Yes, indeed I might agree (see here and see here for examples).
Authors identified some 27 individuals who were tested for vitamin D deficiency between 2012 and 2014 from a population of 56. Over 80% (22/27) had vitamin D levels falling into the deficient or severely deficient range, and none of them had vitamin D levels reaching the bottom end of the typical range (75 - 250 nmol/L). A few other points are worthwhile noting: "In individuals from BME [black and minority ethnic] groups, who were potentially at higher risk of vitamin D deficiency due to increased skin pigmentation, 52.9% (9/17) were tested for vitamin D levels and 100% were deficient or severely deficient."
