Abstract

Abstract: Background: Experiencing socioeconomic disadvantage, poor health, or child maltreatment in early life has negative effects on child development. However, we know little about children who have good developmental outcomes despite experiencing adversity. Methods: This study used de-identified, linked government administrative data from the South Australian Early Childhood Data Project: specifically Australian Early Development Census (AEDC) data for all South Australian born children in their first year of school in 2009, 2012 and 2015 (n = 47, 179) and their corresponding birth, perinatal, school enrolment, hospital admission, emergency department presentation, public housing and child protection data. Latent class analyses constructed multidimensional measures of socioeconomic, health, and maltreatment adversities experienced from birth to age 5. Results: Overall, 49.8% (95% CI 49.2-50.4) of children were on track on all five AEDC domains, but this ranged from 53.7% among children who did not experience high levels of adversity to 13.5% among children with high levels of all three adversities. Conclusions: Among children who experienced high levels of two or three early adversity types, approximately 1 in 5 were developmentally on track. Understanding characteristics of these children who thrive, against the odds, will help identify intervention opportunities to improve child development. Key messages: Compared with children who did not experience high levels of adversity, each additional adversity reduced the likelihood of being developmentally on track by approximately 10% to 15%. Children experiencing socioeconomic or maltreatment adversity were less likely to be developmentally on track than children experiencing health adversity.
