Home Yard and Neighbourhood Physical Environment Latent Class Profiles and Preschooler’s Physical Activity Behaviour
Home yard and neighbourhood physical environment typologies were identified using data from 1,634 preschool children. Relationships between neighbourhood typologies and preschooler physical activity behaviour were investigated. Physical activity was measured using accelerometry and parent-reported outdoor play. Traffic exposure, street connectivity, public transport, residential density, land use mix, vegetation, blue space and home yard size wer…
Environmental phenotypes for healthy weight in children using population-based linked environment and health data
BACKGROUND: Childhood obesity is a major global health challenge, projected to affect one in three children worldwide by 2050. While individual and social factors contribute, increasing evidence highlights the built environment as a key determinant in shaping children's behaviours and weight outcomes. Evidence suggests that neighbourhood design, greenspace access, and food retail availability influence diet and physical activity, but most studies…
Scalability and scaling-up strategy of a physical activity policy intervention in Australian childcare centres
There is an urgent need for scalable interventions to promote physical activity in early childhood. An early childhood education and care (ECEC) physical activity policy intervention with implementation support strategies (Play Active) has been proposed for scale-up in Australia. This study sought to assess the scalability of Play Active and describe the Play Active scaling-up strategy. The Intervention Scalability Assessment Tool was used to ass…
Associations between natural blue and green space and preschool children's movement behaviours
Natural outdoor environments provide important settings for children to engage in physical activity. It is unclear if these relationships also exist in preschool aged children. We examined associations between amount and type of neighbourhood vegetation and blue space, proximity to the beach and preschooler's device‐measured movement behaviours. Accelerometer data from 1081 preschool children were processed into physical activity and sedentary be…
Physical Activity-Related Practices and Psychosocial Factors of Childcare Educators
Limited research investigates early childhood education and care (ECEC) educators' involvement in promoting physical activity. The aim was to identify distinct profiles based on physical activity-related practices and psychosocial factors in ECEC educators and examine how they relate to the amount of time allocated to children's physical activity. A secondary analysis of educator-reported survey data from the Play Active study was undertaken. Edu…

Understanding variations in the built environment over time to inform longitudinal studies of young children's physical activity behaviour - The Beaches project
We know relatively little about the role the neighbourhood built environment plays in promoting young children's physical activity, particularly its longitudinal effect either through repeated exposure to the same environment or through change in exposure by moving from one neighbourhood to another. This study characterised the neighbourhood environment of young children in the PLAYCE cohort study over three timepoints from 2015 to 2023. There we…
Movement behavior policies in the early childhood education and care setting
Background: Meeting 24-h movement behavior guidelines for the early years is associated with better health and development outcomes in young children. Early childhood education and care (ECEC) is a key intervention setting however little is known about the content and implementation of movement behavior polices in this context. To inform policy development this international scoping review examined the prevalence, content, development and impleme…
The moderating role of parent perceptions in relationships between objectively measured neighbourhood environment attributes and pre-schooler’s physical activity
Parents’ Perceptions of the Neighbourhood Built Environment Are Associated with the Social and Emotional Development of Young Children
The influence of the neighbourhood built environment on young children's physical development has been well-documented; however, there is limited empirical evidence of an association with social and emotional development. Parental perceptions of the neighbourhood built environment may act as facilitators or barriers to young children's play and interactions in their local environment. The aim of this study was to examine the associations between …
A cross-sectional study of factors associated with regular dog walking and intention to walk the dog
Interventions to promote dog walking may benefit from increasing intention to dog walk in male owners, forming schedules and routines that involve multiple household members in dog walking, and establishing habits around dog walking. Interventions may also need to address how to overcome barriers and perceived challenges in regards to self-efficacy of dog walking, that may prevent intention from being translated into action

Living liveable? Reside's evaluation of the “Liveable Neighborhoods” planning policy on the health supportive behaviors and wellbeing of residents in Perth, Western Australia
The synthesis of findings suggests that new suburban communities built in accordance with the "Liveable Neighbourhoods" policy have the potential to encourage health supportive behaviors and wellbeing outcomes including transport and recreation walking, and to create neighborhoods with a stronger sense of community where residents may feel safer
The Influence of the Early Childhood Education and Care Environment on Young Children’s Physical Activity
(1) Background: Participation in physical activity is crucial for the healthy growth and development of young children. More robust measurement of environmental influences on children's physical activity in early childhood education and care (ECEC) settings may help resolve inconsistencies in the literature. This study evaluated the reliability of an environmental audit and educator practice survey for assessing ECEC physical, policy, and social …
The Effect of Upgrades to Childcare Outdoor Spaces on Preschoolers’ Physical Activity
Physical inactivity is a significant risk factor for childhood obesity. Preventing obesity in the early years reduces the risk of developing chronic health conditions later. Early childhood education and care (ECEC) services are important settings to establish good preschooler physical activity behaviors. This natural experiment investigated the influence of ECEC outdoor physical environment upgrade on preschoolers' physical activity (aged 2-5 ye…

I'm Just a'-Walking the Dog” Correlates of Regular Dog Walking
Intrapersonal and environmental factors associated with dog walking (N = 483) were examined. A greater proportion of regular (80%) than irregular (59%) dog walkers met the recommended 150 minutes of physical activity per week. Owners who perceived greater social support and motivation from their dogs to walk, and who had access to a dog-supportive park within their neighborhood, were more likely to regularly walk with their dogs, even after adjus…
How important is the land use mix measure in understanding walking behaviour? Results from the Reside study
BACKGROUND: Understanding the relationship between urban design and physical activity is a high priority. Different representations of land use diversity may impact the association between neighbourhood design and specific walking behaviours. This study examined different entropy based computations of land use mix (LUM) used in the development of walkability indices (WIs) and their association with walking behaviour. METHODS: Participants in the …

Can the Neighborhood Built Environment Make a Difference in Children's Development? Building the Research Agenda to Create Evidence for Place-Based Children's Policy
Understanding how dogs encourage and motivate walking
There are both dog and owner factors that are associated with an owner's sense of encouragement, and motivation to walk the dog, which in turn has been found to be associated with dog waking behaviour. These factors may be targeted in future interventions to increase and maintain physical activity levels of both people and pets
The association between dog walking, physical activity and owner’s perceptions of safety
This multi-site international study provides further support for the potential for dog walking to increase levels of daily physical activity. Walking with a dog may be a mechanism for increasing perceptions of neighborhood safety and getting to know the neighborhood, however significant between-country differences exist. Further international research is required to understand the drivers for these between-country differences. Community based pro…
