Vitamins, Breastmilk HIV Shedding, and Child Health - Full Text View

Purpose

The purpose of this study is to analyze stored samples and data collected during the conduct of the study "A Trial of Vitamins in HIV Progression and Transmission" (HD32257). The aims are to examine the effect of vitamin supplementation on HIV infected women during pregnancy on a number of parameters in breastmilk.

Ages Eligible for Study:	18 Years and older (Adult, Senior)
Sexes Eligible for Study:	Female
Accepts Healthy Volunteers:	No
Sampling Method:	Non-Probability Sample

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.

Criteria

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
