Vitamin D deficiency and insufficiency in pregnant women: a longitudinal study
Maternal vitamin D insufficiency is associated with childhood rickets and longer-term problems including schizophrenia and type 1 diabetes. Whilst maternal vitamin D insufficiency is common in mothers with highly pigmented skin, little is known about vitamin D status of Caucasian pregnant women. The...

description | Maternal vitamin D insufficiency is associated with childhood rickets and longer-term problems including schizophrenia and type 1 diabetes. Whilst maternal vitamin D insufficiency is common in mothers with highly pigmented skin, little is known about vitamin D status of Caucasian pregnant women. The aim was to investigate vitamin D status in healthy Caucasian pregnant women and a group of age-matched non-pregnant controls living at 54–55°N. In a longitudinal study, plasma 25-hydroxyvitamin D (25(OH)D) was assessed in ninety-nine pregnant women at 12, 20 and 35 weeks of gestation, and in thirty-eight non-pregnant women sampled concurrently. Plasma 25(OH)D concentrations were lower in pregnant women compared to non-pregnant women (P |

Vitamin D insufficiency is evident in pregnant women living at 54–55°N. Women reporting use of vitamin D-containing supplements had higher vitamin D status, however, vitamin D insufficiency was still evident even in the face of supplement use. Given the potential consequences of hypovitaminosis D on health outcomes, vitamin D supplementation, perhaps at higher doses than currently available, is needed to improve maternal vitamin D nutriture.</description><identifier>ISSN: 0007-1145</identifier><identifier>EISSN: 1475-2662</identifier><identifier>DOI: 10.1017/S0007114509297236</identifier><identifier>PMID: 19331703</identifier><identifier>CODEN: BJNUAV</identifier><language>eng</language><publisher>Cambridge, UK: Cambridge University Press</publisher><subject>25-hydroxycholecalciferol ; Adult ; Biological and medical sciences ; blood plasma ; Blood tests ; Dietary Supplements - utilization ; Feeding.
