Regulatory problems in infancy (e.g., excessive crying and sleeping difficulties) are associated with internalizing (depression and anxiety) and externalizing (aggression, hyperactivity) symptom trajectories across childhood, however, it is unknown whether early screen media exposure exacerbates this association.
We studied 10,170 individuals from the Growing Up in Ireland ’08 cohort. Parents reported on their children’s regulatory problems at 9 months, screen media exposure at 3 years, and internalizing and externalizing symptoms at 3, 5, 7, and 9 years. Presence of regulatory problems at 9 months was associated with higher screen media exposure at 3 years. Further, presence of regulatory problems at 9 months and excessive screen media exposure at 3 years (particularly>2 h) were independently associated with internalizing and externalizing symptoms across childhood.
However, excessive screen media exposure at 3 years did not significantly moderate the association between regulatory problems at 9 months and internalizing and externalizing symptoms.
