title: Vitamin A, beta-carotene, and mother-to-child transmission of HIV.
abstract: The role of maternal vitamin A supplements in decreasing the risk of mother-to-child HIV transmission has been examined in sub-Saharan Africa. Overall, there is no reduction in either mortality or HIV transmission in two recent studies. Contrary to expectations, one study reported an increased risk of transmission using vitamin A plus beta-carotene supplements.
