Elevated background TV exposure over time increases behavioural scores of 18-month-old toddlers.

Aim: To investigate whether trends of TV exposure from age six to 18 months and adult TV programmes were associated with behavioural concerns of 18-month-old Thai toddlers.

Methods: There were 194 healthy infants recruited at age six months and followed up until 18 months of age in this present cohort. TV exposure variables were assessed by interviewing in depth at both six- and 18-month-old visits.
