Cohort study reveals delayed saccadic eye movements in infants from lower-wealth households, indicating early-emerging socioeconomic gaps in neurodevelopment.

Key Points

To determine the developmental onset and trajectory of socioeconomic disparities in elementary visual attention and processing speed among infants in low-resource environments.
Assessed elementary visual behaviors using eye tracking in children at 7, 17, and 36 months in rural South Africa (N=374) and at 30 months in Zambia (N=270).
Evaluated saccadic latency to newly appearing visual targets and socially cued targets against household asset ownership, screen exposure, and physical growth (height-for-age).
Saccadic response latency was inversely associated with household asset ownership, with longer latencies observed in children from poorer households.
The latency gradient emerged as early as 7 months of age, widened between 7 and 36 months, and was not attributable to differences in screen exposure.
Disparities generalized to socially cued pointing gestures and co-occurred with lower height-for-age and developmental milestone scores in less wealthy households.
