|Abstract: ||Maternal vitamin B12 deficiency during pregnancy is an independent risk factor for neural tube defects and other neurological
problems in infants. We determined the vitamin B12 status of 143 pregnant women in Nigeria representing all trimesters who
presented to an antenatal clinic in Jos, Nigeria, using holotranscobalamin II levels (holoTCII), which is a measure of the vitamin
B12 that is available for uptake into tissues. The holoTCII concentration ranged from 13 to 128 pmol/L. Using a cutoff of
40 pmol/L, 36% of the women were classified as vitamin B12-deficient. HoloTCII concentrations correlated negatively with plasma
homocysteine levels (r = −0.24, P = 0.003) and positively with red blood cell folate concentrations (r = 0.28,P < 0.001). These data
underscore the importance of supplementing pregnant women in Nigeria with vitamin B12 in order to ensure adequate vitamin
B12 status and decrease the risk for neural tube defects.|
