More than 2 hours of screen time per day is independently associated with impaired cognitive and executive function in children ages 6 to 7 born after less than 28 weeks of gestation, researchers reported in JAMA Pediatrics.

Betty R. Vohr, MD, professor of pediatrics at Brown University, and colleagues conducted a secondary analysis of a trial conducted by the Eunice Kennedy Shriver National Institute of Child Health and Human Development that included 414 children born extremely early between February 1, 2005 and February 28, 2009.

They evaluated the children between 2012 and 2016, ages 6 years and 4 months to 7 years and 2 months. The children were exposed to either low screen time (less than 2 hours per day; n = 176) or high screen time (more than 2 hours per day; n = 238).

Of the 414 children, 227 were male (55%) and the mean birth weight was 870.6 g. A total of 266 children (64%) had a computer and/or television in the bedroom.

According to Vohr and colleagues, high screen time was associated with younger maternal age compared to low screen time (mean 27 vs 28.7 years) and being black (black 39% vs white 35%). Having a television and/or computer in the bedroom was also associated with a younger maternal age (mean 26.7 vs. 29.5 years) and being black (black 42% vs. white 33%). In addition, having a screen in the bedroom was associated with a lower mother’s education level and having public insurance.

According to the Wechsler Intelligence Scale for Children IV, children with high screen time had significantly lower full-scale mean IQ scores after adjusting for center, male gender, gestational age, and social determinants of health (mean difference, -3.92).

High screen time was also associated with an increase in executive function deficits, including metacognition (8.18), global executive function (7.49), inhibition (-0.79), and inattention (3.32).

In addition, a television and/or computer in the bedroom was associated with an increase in inhibition (–0.80) and hyperactivity/impulsivity (3.5).

“Our findings support the need for clinicians to discuss both the benefits and risks of screen time with families and share AAP recommendations,” the authors wrote.
