The Pediatric HIV/AIDS Cohort Study (PHACS), the largest ongoing longitudinal
study of perinatal HIV-infected (PHIV) and HIV-exposed, uninfected (PHEU)
children in the United States, comprises the Surveillance Monitoring of
Antiretroviral Therapy [ART] Toxicities (SMARTT) Study in PHEU children and the
Adolescent Master Protocol (AMP) that includes PHIV and PHEU children ?7 years.
Although race/ethnicity is often used to assess health outcomes, this approach
remains controversial and may fail to accurately reflect the backgrounds of
ancestry-diverse populations as represented in the PHACS participants.In this
study, we compared genetically determined ancestry (GDA) and self-reported
race/ethnicity (SRR) in the PHACS cohort. GDA was estimated using a highly
discriminative panel of 41 single nucleotide polymorphisms and compared to SRR.
Because SRR was similar between the PHIV and PHEU, and between the AMP and SMARTT
cohorts, data for all unique 1958 participants were combined.According to SRR,
63% of study participants identified as Black/African-American, 27% White, and
34% Hispanic. Using the highest percentage of ancestry/ethnicity to identify GDA,
9.5% of subjects were placed in the incorrect superpopulation based on SRR. When
?50% or ?75% GDA of a given superpopulation was required, 12% and 25%,
respectively, of subjects were placed in the incorrect superpopulation based on
SRR, and the percent of subjects classified as multiracial increased. Of 126
participants with unidentified SRR, 71% were genetically identified as
Eurasian.GDA provides a more robust assessment of race/ethnicity when compared to
self-report, and study participants with unidentified SRR could be assigned GDA
using genetic markers. In addition, identification of continental ancestry
removes the taxonomic identification of race as a variable when identifying risk
for clinical outcomes.
