ABSTRACT
OBJECTIVE: Descriptive studies and clinical reports have suggested that human immunodeficiency virus (HIV)-positive children are at risk for behavioral problems. Inadequate control groups and sample sizes have limited the ability of investigators to consider multiple influences that place HIV-positive children at risk for poor behavioral outcomes. We examined the unique and combined influences of HIV, prenatal drug exposure, and environmental factors on behavior in children who were perinatally exposed to HIV. METHODS: Participants included 307 children who were born to HIV-positive mothers (96 HIV infected and 211 seroreverters) and enrolled in a natural history, longitudinal study of women to infant HIV transmission. Caregivers completed parent behavioral rating scales, beginning when the children were 3 years old. Data were also collected on prenatal drug exposure; child age, gender, and ethnicity; caregiver relationship to child; and birth complications. RESULTS: Multivariate analyses comparing the HIV-infected children with perinatally exposed but uninfected children from similar backgrounds failed to find an association between either HIV status or prenatal drug exposure and poor behavioral outcomes. The strongest correlates of increased behavioral symptoms were demographic characteristics. CONCLUSIONS: This study suggests that although a high prevalence of behavioral problems does exist among HIV-infected children, neither HIV infection nor prenatal drug exposure is the underlying cause. Rather, other biological and environmental factors are likely contributors toward poor behavioral outcomes.

To determine the association between genital tract shedding of human immunodeficiency virus (HIV) type 1 and vertical transmission, a case-control substudy was conducted within the Women and Infants Transmission Study. Antenatal cervicovaginal lavage specimens were assessed for HIV-1 RNA in the supernatant and HIV-1 RNA and DNA in cell pellets. Multivariate analyses compared 26 women who transmitted HIV to their infants with 52 women who did not; 33% received combination antiretroviral therapy, and 65% received monotherapy. Adjusted odds ratios (ORs) for the presence (OR, 3.42; 95% confidence interval [CI], 0.76-15.4; P=.11) and titer (OR, 1.66; 95% CI, 0.93-2.99; P=.09) of HIV-1 DNA suggested that there is an independent association with vertical transmission. When analyses were restricted to vaginal and nonelective cesarean deliveries, each one-log increase in mean titer of HIV-1 DNA was associated with a significantly higher risk of transmission (OR, 2.28; 95% CI, 1.09-4.78; P=.03). The cell-associated genital tract compartment is important in the pathophysiology and prevention of vertical HIV-1 transmission.
