The aims of this project is to examine the temporal trends in the duration and type of screen usage at 2 years, 45 months (3.75 years) and 54 months (4.5 years) in the Growing Up in New Zealand cohort. We will also determine the associations between screen usage at 2 years of age a range of physical, behavioural, and social outcomes. Response to technology use items at 2 years will be treated as exposure variables.

New research sheds light on how Kiwi pre-schoolers’ use of screen media may affect the development of executive functions which help children to manage their impulses and behaviour.
