More Screen Time in Early Childhood Tied to Lower Reading & Math Scores

A recent study using data from over 5,000 Canadian children shows that high screen time in early years links to poorer academics later in elementary school. Each extra hour of daily screen use reduced the odds of better reading and math scores by about 10%. 

Researchers analyzed screen habits of kids ages 0–5, then matched that to their grade 3 and grade 6 standardized test scores.  They accounted for family, health, and socio-economic factors, but still found a strong association. 

The test results showed that higher screen time, especially for TV and general digital media, was linked to lower performance in grade 3 reading, grade 3 math, and grade 6 math.  Video game use especially affected grade 3 reading scores. 

Authors emphasize that screen quality and context also matter—not just duration. What children watch, and how, plays a big role.  They call for better tools to measure and monitor screen use in kids. 

Pediatricians and family doctors can help by supporting parents to build balanced routines that include screen limits, sleep, movement, and interactive play.  The study suggests early screen habits may set a foundation that influences learning years later.
