Factors associated with early clinical recognition of children with perinatal human immunodeficiency virus infection. Northern California Pediatric HIV Consortium.

Surveillance of children born to women with human immunodeficiency virus (HIV) infection at five pediatric regional centers assessed times and patterns of clinical recognition in these children. Regional HIV seroprevalences among childbearing women were used to assess the proportion of identified children born to HIV-infected women. In total, 415 children with perinatal HIV exposure were identified. Early age at first HIV evaluation was significantly associated with maternal intravenous drug use (3.2 vs. 7.2 months for other or unknown maternal risk, P = .01), birth county with population > 500,000 (3.5 vs. 8.2 months for population < or = 500,000, P = .003), and hospital with routine HIV screening of pregnant women (0.1 vs. 8.8 months for no screening, P = .006). Race did not correlate with age at first evaluation. Using maternal HIV seroprevalence rates for 1988-1991, 34%-50% of the expected number of infants born to HIV-infected women were in clinical care. Perception of increased maternal risk for HIV infection was associated with early clinical recognition of infants of HIV-infected women.
