Vitamin D deficiency in UK Asian families: activating a new concern.

Vitamin D has steroid hormonal effects which can produce clinical symptoms and signs unrelated to calcium homoeostasis. Its deficiency has been implicated as a risk factor for diabetes, ischaemic heart disease, and tuberculosis in Asians. In this review, the incidence, aetiology, prevention, and treatment of symptomatic vitamin D deficiency in childhood are considered. A renewed public health campaign is required in the UK to address the continuing problem of vitamin D deficiency in Asian families. [ABSTRACT FROM AUTHOR]
