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.
A range of outcome variables will be analysed including physical, behavioural, and social variables from parental proxy interview response and individually administered tests. The information will be used to generate relevant, accurate, and evidence-based policy relating to screen usage in pre-schoolers
