To assess the relationship between maternal human immunodeficiency virus (HIV) type 1 RNA level, other important covariates, and mother-to-infant (vertical) transmission of HIV-1, third trimester repository specimens from 160 HIV-1-seropositive women enrolled in the Mothers and Infants Cohort Study between 1986 and 1991 were assayed in batch for HIV-1 RNA.
A significant association between peripheral blood HIV-1 RNA level and vertical transmission remained after controlling for CD4 cell level, duration of ruptured membranes, « hard » drug (cocaine and heroin) use, and frequency of sexual activity during pregnancy.
However, the association was attenuated among women with advanced HIV infection and those with a high frequency of sexual activity during pregnancy.
In these settings, interventions that target risk factors other than virus load may be particularly important for preventing vertical transmission of HIV-1.
