Brief summary: In the prospective population-based Growing Up in Singapore Toward Healthy Outcomes (GUSTO) study (n=437 children, 51.9% boys), the effect of parent-reported screen time in infancy was tested on EEG characteristics and correlated to cognitive outcome. Mean daily screen time at 12 months of age was 2 hours. Infant screen time was associated with altered cortical EEG activity at 18 months and was suggested to explain observed alterations in attention and ...
