Abstract
This study is aiming to evaluate the association between
television viewing during childhood and long-term adolescent
neuropsychological outcomes and the potential explanatory
pathways. This is a longitudinal study based on 278 children
participating in the INMA birth cohort (1998) in Menorca Island,
Spain. The exposure is parent-reported duration of child
television viewing (hours per week) at 6 and 9 years of age.
Neuropsychological outcomes were assessed at 14 years of age
using the N-back test. Behavioral outcomes at 14 years of age
were assessed using the Strengths and Difficulties Questionnaire
(SDQ) and school performance was assessed by the global school
score. Regression models were developed to quantify the
associations between duration of television viewing and
neuropsychological outcomes adjusted for child and parents'
characteristics. The average of weekly TV viewing from 6 to 9
years was 9.2 h (SD: 4.1). Only N-back test outcomes exhibited
statistically significant differences in crude models. Children
viewing > 14 h per week tended to show larger latencies in
working memory reaction time (HRT in ms), beta (CI) = 53
(0-107). After adjusting for potential social confounders, the
association weakened and became non-significant but adverse
trends were slightly preserved. Early life TV viewing was not
associated with adolescent neuropsychological outcomes after
adjustment for potential confounders. Further research including
larger and exhaustive population-based cohort studies is
required in order to verify our conclusions.
