Study Population
The data and samples used in this study are from HIV-infected pregnant women who participated in the "Trial of Vitamins in HIV Transmission and Progression".
Between 1995 and 1997, 1,078 African, HIV positive women who were between gestatopm weeks 12 and 27 were recruited.
They were followed until August 2003.
This study was conducte among 771 of these women, for whom breast milk samples were available at delivery.
There were no differences in baseline characteristics between this subset and the originally randomized group of 1,069.
Description
This study is analyzing samples previously collected from the study "A Trial of Vitamins in HIV Progression and Transmission" (HD32257).
The inclusion criteria in this study was:
- HIV infected women presenting to antenatal care between 12 and 27 weeks of gestation
