Background: Vitamin D is essential for the normal functioning of a diverse range of metabolic processes, especially bone health. It is widely appreciated that the elderly are at increased risk of vitamin D insufficiency, but it is less well known that people with intellectual disability are also at increased risk.
Objective: This article summarises the issues regarding vitamin D in people with intellectual disability, making recommendations about screening, management and follow up.
Discussion: The prevalence of intellectual disability in the Australian population has been estimated at just over 1%, implying that most general practitioners will care for several people with intellectual disability. Relatively simple steps are likely to have a significant impact on the health of this vulnerable group of people.
