Summary:Gbemisola O Boyede,1,2 Foluso EA Lesi,2 Veronica C Ezeaka,2 Charles S Umeh3 1Division of Developmental Paediatrics, School of Child and Adolescent Health, Red Cross War Memorial Children&rsquo;s Hospital, University of Cape Town, Cape Town, South Africa; 2Department of Paediatrics, 3Clinical Psychology Unit, Department of Psychiatry, Lagos University Teaching Hospital, Lagos, Nigeria Background: In this study, we sought to evaluate the influence of sociodemographic factors, ie, age, sex, socioeconomic status, maternal education, and human immunodeficiency virus (HIV) status, on cognitive performance in school-aged HIV-infected Nigerian children. Methods: Sixty-nine HIV-positive children aged 6&ndash;15 years were matched with 69 HIV-negative control children for age and sex. The children were subdivided for the purpose of analysis into two cognitive developmental stages using Piaget&rsquo;s staging, ie, the concrete operational stage (6&ndash;11 years) and the formal operational stage (12&ndash;15 years). All participants underwent cognitive assessment using Raven&rsquo;s Standard Progressive Matrices (RPM). Sociodemographic data for the study participants, ie, age, sex, socioeconomic status, and level of maternal education, were obtained using a study proforma. Logistic regression analyses were used to determine associations of HIV status and sociodemographic characteristics with RPM cognitive scores. Results: The overall mean RPM score for the HIV-positive children was 18.2 &plusmn; 9.8 (range 8.0&ndash;47.0) which was significantly lower than the score of 27.2 &plusmn; 13.8 (range 8.0&ndash;52.0) for the HIV-negative children (P < 0.001). On RPM grading, 56.5% of the HIV-positive children had cognitive performance at below average to intellectually defective range. Below average RPM scores were found to be significantly associated with younger age (6&ndash;11 years), positive HIV status, lower socioeconomic status, and low level of maternal education. Conclusion: Younger age, poor socioeconomic status, and low level of maternal education were factors apart from HIV infection that were significantly associated with low cognitive function in school-aged HIV-infected Nigerian children.
