Interpregnancy intervals and child development at age 5: a population data linkage study.

Objective: To investigate the associations between interpregnancy intervals (IPIs) and developmental vulnerability in children's first year of full-time school (age 5).

Design: Retrospective cohort study using logistic regression. ORs were estimated for associations with IPIs with adjustment for child, parent and community sociodemographic variables.

Associations between biological and sociodemographic risks for developmental vulnerability in twins at age 5: a population data linkage study in Western Australia.

Objective: To investigate the prevalence of, and associations between, prenatal and perinatal risk factors and developmental vulnerability in twins at age 5.

Design: Retrospective cohort study using bivariate and multivariable logistic regression.

Setting: Western Australia (WA), 2002-2015.

Associations between clusters of early life risk factors and developmental vulnerability at age 5: a retrospective cohort study using population-wide linkage of administrative data in Tasmania, Australia.

Objective: Early childhood is a critical time to address risk factors associated with developmental vulnerability. This study investigated the associations between clusters of early life risk factors and developmental vulnerability in children's first year of full-time school at age 5.

Design: A retrospective cohort study.

Multiple risk exposures for reading achievement in childhood and adolescence.

Background: Literacy is championed as a pathway out of poverty, yet it is vulnerable to the risk circumstances it seeks to mitigate. This study explored the developmental circumstances that gave rise to stark inequalities in reading achievement in Australian children across 6 years of school.

Methods: We used data from : the Longitudinal Study of Australian Children linked to Australia's National Assessment Program-Literacy and Numeracy across school years 3, 5, 7 and 9.
