Article Abstract
Background: It has been proposed that early-life screen use can impact the development of attention deficit hyperactivity disorder (ADHD) symptoms. Some studies have supported a weak association between higher levels of screen time and ADHD symptoms; however, this association is vulnerable to confounding and a causal explanation remains controversial.
Methods: To help address confounding in this association, we conducted inverse probability of treatment weighting (IPTW) analyses in a large UK-representative longitudinal sample to examine the impact of TV/video viewing at age 3 on ADHD symptoms at age 5.
Results: Adjusting for confounding, we found that both no TV/video viewing and viewing more than 3 h of TV/video compared to between 1 and 3 h were associated with increased ADHD symptoms. However, the effect of no TV/video viewing was mirrored in a negative outcome control analysis, suggesting potential residual confounding.
Conclusions: Results are consistent with claims that high levels of TV/video viewing in preschool years may impact the development of ADHD symptoms. Trial-based research which examines the impact of reducing high levels of TV/video viewing in this age group would be merited to further illuminate this association and assess whether it is likely to reflect a causal effect.
Clinical Trial Number: Not applicable.

Background: Television (TV), video games, PC and devices such as tablets and smart phones have become part of everyday life at an ever-younger age. Increased screen time correlates with unhealthy eating habits among children.
Methods: 374 children aged 9-12 years and their parents (n = 159), from 3 schools in Lemnos and 5 schools in Thessaloniki, Greece, took part in this cross-sectional study.

Demographic, parental and home environment correlates of traditional and mobile screen time in preschool-aged children.

Objectives: Research on the correlates of screen time in young children, that could be targeted in future interventions to improve healthy development, has primarily focused on TV viewing with little consideration of mobile devices. The objectives of this study were to examine the associations between a range of demographic, parental, and home environment correlates and preschool-aged children's TV/video viewing, video/computer game playing, and total screen time across traditional and mobile devices.
Methods: The results of this cross-sectional study are based on 106 preschool-aged children (3-5 years) and their parents recruited in 2018 in Edmonton, Alberta.

Background: Preschool children spend a significant proportion of their waking hours being sedentary. Parents play a critical role in developing and shaping their children's lifestyle behaviours, particularly in the early years of life. This study aims to assess parental perceptions, attitudes and knowledge of their preschool children's sedentary behaviours and the association with children's television (TV)/video/DVDs viewing and total screen time.
