Barriers and enablers to promoting grandchildren’s physical activity and reducing screen time: a qualitative study with Australian grandparents

With an increasing number of grandparents providing care to their grandchildren, calls have been made for these caregivers to be considered important stakeholders in encouraging children's engagement in health-promoting behaviors, such as physical activity.

Preschool children’s physical activity in the home, childcare and neighbourhood environment: A latent profile analysis using device-based measures

Based on the socioecological conceptual model, the physical environment within the home, childcare and neighbourhood domains are key factors that influence preschool children's physical activity; however, the relative importance of each of these domains for preschool children's physical activity is unclear.

The moderating role of parent perceptions in relationships between objectively measured neighbourhood environment attributes and pre-schooler's physical activity: Findings from the PLAYCE study

We examined the moderating effects of parent perceptions of the neighbourhood environment on associations between objectively measured neighbourhood environment attributes and physical activity among pre-schoolers. The number of neighbourhood parks was positively associated with pre-schooler energetic play when parents had above average perceptions of access to services.

Interpregnancy interval and adverse birth outcomes: a population-based cohort study of twins

To investigate associations between interpregnancy intervals (IPIs) and adverse birth outcomes in twin pregnancies.

Where are preschoolers active in childcare centers? A hot-spot analysis using GIS, GPS and accelerometry data

This study investigated where preschool children were more or less active in outdoor play areas in Early Childhood Education and Care (ECEC) centers using a novel method of combined device-measured physical activity, spatial data and on-site audit data.

Meeting the Australian 24-Hour Movement Guidelines for the Early Years is associated with better social-emotional development in preschool boys

24-hour Movement Guidelines for the Early Years promote that achieving all three-movement behaviour (sleep, sedentary behaviour and physical activity) recommendations is important for child health and development. We examined the association between meeting all, none and combinations of the Australian 24-Hour Movement Guidelines for the Early Years and social-emotional development in 1363 preschool (2-5 years) boys (52%) and girls.

Educators’ Barriers and Facilitators to Physical Activity Policy Implementation in the Childcare Setting: Qualitative Findings From the Play Active Project

We explored childcare educators’ perceived barriers and facilitators to policy implementation in order to inform the development and implementation of an early childhood education and care (ECEC) specific physical activity policy. This study was part of the Play Active (2019-2023) project which aimed to develop, implement and evaluate evidence-based physical activity policy to improve physical activity levels in children attending ECEC.

Is early childhood development impeded by the birth timing of the younger sibling?

This study investigated whether the timing of birth of the younger siblings was associated with the risk of the older siblings’ developmental vulnerability in early childhood.

Individual, Social, and Environmental Correlates of Energy Drink Use Among Adolescents

To investigate the correlates of adolescent energy drink use using a socioecological approach to inform future interventions.

Association between vaccination status, symptom identification and healthcare use: Implications for test negative design observational studies

To test the internal validity of the test-negative design (TND) by investigating associations between maternal influenza vaccination, and new virus detection episodes (VDEs), acute respiratory illness, and healthcare visits in their children.
