Researchers aimed to study the association between television-watching in the earlier years of life and subsequent parents’ concerns about decreased visual acuity in their elementary school-aged child.

Parent's worries about their child's reduced visual acuity during the school years were picked up from yearly questionnaires conducted for the Longitudinal Survey of Newborns in the Twenty-First Century, which included all babies born in Japan during one of two periods (N = 47,015).

Results:
--Television-/video-watching as the main form of play of children at the ages of 1.5 years and 2.5 years was significantly associated with parents’ concerns for their child’s decreased visual acuity raised once or more in 6 surveys conducted between the ages of 7 and 12 years.

--The association remained significant after adjustment for confounding variables, including child’s sex, preterm birth, multiple birth, mother’s age at delivery, mother’s and father’s education, and residential area.

--Longer daily duration of television-watching at 2.5 years was significantly associated with concerns for the child’s decreased visual acuity between the ages of 7 and 12 years, but not at the ages of 3.5, 4.5, and 5.5 years.

--The association remained significant in a sensitivity analysis of 28,820 children who participated in all six surveys.

Conclusively, longer daily exposure to television in children in the earlier years of life was associated with parent's subsequent concerns about decreased visual acuity in their elementary school-aged child.
