title: Attention is needed to the high prevalence of vitamin D deficiency in our older population.
abstract: The aim of this study was to assess the prevalence of vitamin D deficiency in females residing in one large, aged-care facility in Auckland. Thirty-nine residents, most of whom were able to go outdoors without assistance, were tested for midwinter 25-hydroxyvitamin D, and, of these, 36 were tested again in midsummer. The prevalence of frank hypovitaminosis (<10 microg/L) was found to be 49% in midwinter and 33% in midsummer. The vitamin D status of such at-risk individuals could be normalised either by 15-30 minutes of daily sun exposure or, alternatively, a programme of supplementation.
