Abstract: Background: Evidence shows that antiretroviral (ART) exposure is associated with neurodevelopmental delays in human immunodeficiency virus (HIV)-exposed uninfected (HEU) children. However, there are few insights into modifiable maternal and child factors that may play a role in improving neurodevelopment in HEU children. We used a parent-centric neurodevelopment tool, Ages & Stages Questionnaire (ASQ) to examined neurodevelopment in HEU children at 12–24 months of age, and associations with maternal and child factors. Methods: 505 HIV-infected women (initiated ART pre- or during pregnancy) with live singleton births attending primary health care were enrolled; 355 of their HEU children were assessed for neurodevelopment (gross motor, fine motor, communication, problem solving and personal-social domains) at 12–24 months using age-specific ASQ administered by a trained fieldworker. Associations with maternal and child factors were examined using logistic regression models. Results: Among mothers (median age 30 years, IQR, 26–34), 52% initiated ART during pregnancy; the median CD4 count was 436 cells/μl (IQR, 305–604). Most delayed neurodevelopment in HEU children was in gross (9%) and fine motor (5%) functions. In adjusted models, maternal socio-economic status (aOR 0.42, 95% CI 0.24–0.76) was associated with reduced odds of delayed gross-fine motor neurodevelopment. Maternal age ≥35 years (aOR 0.22, 95% CI 0.05–0.89) and maternal body mass index (BMI)
