Vitamin D concentrations in pregnant women with diabetes attending for antenatal care in Far North Queensland

Serum concentrations of vitamin D were measured in 101 pregnant women with diabetes, both pre-existing and gestational, who attended for antenatal care in Cairns Base Hospital. Eighty-two (81.2%) had sufficient concentrations of vitamin D, 12 (11.9%) had levels indicating insufficiency and 7 (6.9%) were deficient. These findings contrast with those in the general population of pregnant women in the region, among whom 93.1% have been shown to have sufficient levels. The study contributes to the ongoing debate around the need for universal antenatal vitamin D screening in Australia.
