    Abstract

    Background. There is limited evidence about the cognitive performance of older adolescents with perinatally-acquired HIV (PHIV+) compared to HIV-negative (HIV-) adolescents.

    Methods. 296 PHIV+ aged 12-21 and 97 HIV- aged 13-23 completed 12 tests covering 6 cognitive domains. HIV- adolescents were siblings of PHIV+ and/or had an HIV positive mother. Domain-specific and overall (NPZ-6) z-scores were calculated for PHIV+ with and without CDC class C disease and HIV-. Linear regression explored predictors of NPZ-6.

    Results. 125(42%) PHIV+ and 31(32%) HIV- were male, 251(85%) and 69(71%) were black African, and median age was 16[IQR 15,18] and 16[14,18] years respectively. In PHIV+, 247(86%) were on ART, and 76(26%) had a previous CDC C diagnosis. Mean NPZ-6 scores were -0.81 (standard deviation 0.99) in PHIV+ with a CDC C diagnosis, -0.45 (0.80) in PHIV+ without CDC C, and -0.32 (0.76) in HIV- (p<0.001). After adjustment, there was no difference in NPZ-6 between PHIV+ without a CDC C and HIV- participants (adjusted coefficient -0.01 (95%CI -0.22, 0.20) for PHIV+ no C versus HIV-). PHIV+ with CDC C scored below the HIV- group (adjusted coefficient -0.44 (-0.70, -0.19)). Older age predicted higher NPZ-6 score, whilst black African ethnicity and worse depression predicted lower NPZ-6. In a sensitivity analysis including PHIV+ only, no HIV-related factors apart from CDC C were associated with NPZ-6.

    Conclusions. Cognitive performance was similar among PHIV+ without CDC C diagnoses and HIV-, and indicated relatively mild impairment compared to normative data. The true impact on day-to-day functioning needs further investigation.
