Regulatory problems in infancy (e.g., excessive crying and sleeping difficulties) are associated with internalising (depression and anxiety) and externalising (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 internalising and externalising 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 internalising and externalising symptoms across childhood.
However, excessive screen media exposure at 3 years did not significantly moderate the association between regulatory problems at 9 months and internalising and externalising symptoms.
