[Vitamin D and pregnancy: value of a single dose in the third trimester. Comparative study of 100 cases]. / Vitamine D et grossesse: intérêt d'une dose unique au troisième trimestre. Etude comparative sur 100 cas.

A comparative study (100 treated subjects, 100 controls) was carried out at the Centre Hospitalier at Meaux during the winter of 1984-85 in which pregnant women were given single doses of vitamin D to be taken at the seventh month of pregnancy. The results obtained for neonatal blood calcium levels clearly demonstrated the value of vitamin D supplements in pregnant women. This study was original in that a single dose of vitamin D was provided; this led to almost perfect therapeutic observance (99%).
