Prevalence of vitamin D deficiency in a North London antenatal population.

Abstract

We evaluated the prevalence of vitamin D deficiency in the antenatal patients attending North Middlesex University Hospital between March 2008 and March 2009. A prospective study of maternal levels of vitamin D at booking. The prevalence of both deficient and insufficient levels of 25[OH]D was 87.6% across all included patients. There is a high prevalence of asymptomatic vitamin D deficiency in the antenatal booking population.
