Objectives:
Cross-sectoral linked administrative data provides a powerful tool for population-level evaluations of child disadvantage. We examined individual-and area-level indicators of disadvantage in early childhood in Australia and estimated their associations with children's developmental outcomes at school entry.
Study Design:
Cross-sectional study.
Methods:
We drew on data from the Person Level Integrated Data Asset (PLIDA) involving children born in Australia from 01/01/2012 to 31/07/2013, who commenced full-time schooling in 2018 and participated in the Australian Early Development Census (AEDC) (N = 274,123). Individual-level disadvantage was measured using 22 early childhood indicators across four pre-determined social determinant lenses (sociodemographic, geographic, health conditions, and risk factors). Area-level disadvantage was assessed using the Socio-Economic Indexes for Areas (SEIFA), based on each child's residential address. Teacher-reported poor developmental outcomes were assessed at school entry (4-6 years) in the AEDC.
Results:
The percentage of children exposed to different aspects of individual-level disadvantage ranged from 0.2 % (parental death) to 58.8 % (parental mental health issues). There was substantial variation in children's experiences of individual-level disadvantage by geography. The associations between individual-and area-level disadvantage and poor developmental outcomes varied, with the individual-level indicator 'child not regularly read to at home' having the strongest association (risk ratio = 4.06, 95 % CI: 4.00 to 4.11). A dose-response relationship was observed, with exposure to an increasing number of child disadvantage indicators associated with poorer developmental outcomes.
Conclusion:
Addressing children's experiences of multidimensional disadvantage requires cross-sectoral strategies that combine universal and proportionately targeted supports responsive to both individual-and area-level needs.
