A new study, (Obaapa VitaA) in Ghana showed that vitamin A supplementation to women of child-bearing age in poor nations does not reduce maternal death rates. The Ghana findings contradicted previous results from a trial in Nepal which showed a 44% decrease in maternal death among women given vitamin A.
The researchers conducted a randomised and double-blind trial in 7 districts in the Brong Ahafo Region of Ghana. Participants were randomly assigned to vitamin A supplement or placebo capsule orally every week. They found that there was no statistically significant difference between the intervention and the control groups.
The author, Professor B Kirkwood at The London School of Hygiene and Tropical Medicine concluded that "the results of this trial in Ghana vindicate the decision not to change safe motherhood policy immediately after the Nepal trial."
