The “Aftermath” of Toddlers Watching TV: Affecting Brain Development & Life Habits
Linda Pagani of the University of Montreal, Canada as well as Bowling Green State University and University of Michigan,
USA studied >1300 children born in 1997-1998, Quebec, Canada. Parent-reported data on weekly hours of TV exposure
at 29 and 53 months of age; parent and teacher reports of academic, psychosocial, and health behaviors and BMI (body
mass index: weight in kilograms divided by height in meters squared) at 10 years of age (fourth-grade) were collected.
It was published in the May Issue, Archives of Pediatric and Adolescent Medicine, American Medical Association: every
additional hour of TV exposure at 29 months corresponded to 6% decreases in mathematics achievement; 10% increases
in victimization by classmates; 13% decreases in time spent doing weekend physical activities; higher consumption scores
for soft drinks by 9%; and 5% increases in BMI. Pagani opined that, as the brains of young children are rapidly developing;
passive intellectual and physical activities through watching TV replacing real life interpersonal relationships have long-
term effects on their psychosocial and lifestyle characteristics in later life.
