Abstract
INTRODUCTION: The over 14 million African children who are HIV-exposed but uninfected (CHEU) are at risk for poor health outcomes, including neurodevelopmental conditions such as autism; however, no study to date has examined autism in CHEU in Africa, where the vast majority of these children live. Scalable diagnostic and neurobehavioural tools, including powerful, low-cost approaches such as eye-tracking, for detection and study of mechanistic neural processes are necessary to advance autism research in these settings. The objective of this study is to examine autism diagnostic outcomes and eye-tracking biomarkers in relation to CHEU while at the same time building capacity for neuro-health research in Kenya. METHODS AND ANALYSIS: This study will leverage a longitudinally assessed cohort of CHEU and children who are HIV-unexposed and uninfected (CHUU) with well characterised HIV-related and contextual exposures. We will first determine and compare autism diagnostic outcomes between young CHEU and CHUU across a large cohort (n=850) of Kenyan children using research-grade autism assessment tools, and, second, determine whether neurobehavioural eye-tracking markers predict autism outcomes across this cohort. ETHICS AND DISSEMINATION: Human subjects approvals have been obtained from Moi University Institutional Review and Ethics Committee (IREC; IREC/909/2024; Approval #0004835), Kenya's National Commission for Science, Technology and Innovation (NACOSTI; Reference #NACOSTI/P/25/415028), the Institutional Review Board of the Indiana University School of Medicine (Protocol #23171), with reliance agreements executed with Purdue University and Boston University. Dissemination of findings will occur through multiple channels within the research and clinical community, including peer-reviewed journal publications and conference abstracts and presentations. As part of capacity building efforts, the research team will also communicate study results to policy makers, the lay public and other health systems involved in the care of young children with disabilities via study-hosted workshops and conferences.
