Disadvantaged areas experience higher levels of loneliness than advantaged areas, though studies rarely identify environmental determinants of neighbourhood inequity in loneliness. We studied the contribution of the quantity and quality of green space to neighbourhood inequity in loneliness in three buffer sizes (400 m, 800 m, 1600 m), using cross-...

Children consistently exposed to positive, stimulating environments, including their spatial neighbourhood, experience foundations for ongoing optimal development. Recognition of the neighbourhood as a mechanism to enhance wellbeing is reflected in the United Nation's New Urban Agenda. Through a series of innovations and advancements, this paper ai...

Disadvantaged areas have higher loneliness levels than advantaged areas, though studies rarely identify objective built environment determinants of loneliness by neighbourhood disadvantage. We studied the contribution of objective walkability components (residential density, street connectivity, and land use mix) and overall walkability in the rela...

Background Free-fare public transport policies potentially increase walking to transport stops, but may replace other active travel modes with unknown effects on total active travel. We compared active travel behaviour of children living in a Finnish city with a free-fare public transport to a reference city. Methods Children were recruited from p...

Neighbourhood-level interventions offer a promising opportunity to promote child mental health at a population level; however, neighbourhood effects are still regarded as a 'black box' and a better understanding of the specific design elements, such as public open space, is needed to inform actionable policy interventions. Methods: This study lev...

Healthy development in the early years lays the foundations for children’s ongoing physical, emotional, and social development. Children develop in multiple contexts, including their local neighbourhood. Neighbourhood-built environment characteristics, such as housing, walkability, traffic exposure, availability of services, facilities, and parks,...

This paper explores neighborhood-built environment features related to ‘better than expected’ and ‘as expected’ early childhood development outcomes (ECD) in 14 Australian disadvantaged communities. This paper draws from mixed methods data collected in the Kids in Communities Study – an Australian investigation of community effects on ECD – in comm...

Background Outdoor public recreation spaces are important settings for leisure and physical activity. Adolescents’ use of these spaces may contribute to social connectedness via social interaction with peers and the community in these settings. However, research on this topic is limited. This exploratory study examined associations of frequency of...

Background: Outdoor public recreation spaces are important settings for leisure and physical activity. Adolescents’ use of these spaces may be related to their social connectedness; however, research on this topic is limited. This study examined associations of frequency of visitation and physical activity in outdoor public recreation spaces with s...

There is increasing international interest in place-based approaches to improve early childhood development (ECD) outcomes. The available data and evidence are limited and precludes well informed policy and practice change. Developing the evidence-base for community-level effects on ECD is one way to facilitate more informed and targeted community...

Background Mental health inequities are shaped by the environments where children develop, including neighbourhoods. Children living in disadvantaged neighbourhoods tend to have poorer development outcomes, yet little evidence has examined positive mental health outcomes, like competence, in young children. Methods We examined associations between...

Background Mental health inequities can emerge early in life and are shaped by the daily conditions and environments where children develop, including neighbourhoods. Synthesizing evidence around neighbourhoods, disadvantage, and early childhood mental health can advance understandings of neighbourhood features (e.g. housing, parks) associated with...

Trajectories of physical activity and sedentary time (SED) may differ between subgroups of youth. The aim of this study was to identify group‐based dual trajectories of physical activity and SED and explore individual, social and environmental correlates of these trajectories. Longitudinal data (three time‐points, baseline 2011‐12) of Spanish youth...

The first five years of a child's life are crucial in laying the foundation for their health and developmental trajectory into adulthood. These early years are especially influenced by the surrounding environments in which children live and grow. A large international body of evidence demonstrates that children who experience disadvantage tend to f...

Adolescents have the potential to be active in multiple places across weekdays and weekends. While the built environment features around home are known to be important for adolescents' physical activity, specific built environment features that facilitate physical activity outside the home neighbourhood are not well explored. Given that adolescents...

Background: Children’s habitual physical activity, including active travel and catching public transit (walking and cycling to and from destinations), and independent mobility (mobility without an adult) have decreased. Public transit trips are physically active and can provide access to hobbies independent of parents, but there is no device- measu...

Background Children residing in neighbourhoods of high deprivation are more likely to have poorer health, including excess body size. While the availability of unhealthy food outlets are increasingly considered important for excess child body size, less is known about how neighbourhood deprivation, unhealthy food outlets and unhealthy dietary behav...

Without accurate awareness of features within the built environment, the availability of a supportive built environment alone may not be sufficient to influence physical activity levels. We examined the moderating effects of concordance/discordance between selected objective and perceived built environment features in the relationship between objec...

Background: Increasing emphasis has been placed on improving physical activity levels through multilevel interventions. This study aims to examine moderating effects of neighborhood safety (crime and traffic) and social support (from parent and sibling/peer) for physical activity in the relationship between the built environment and moderate-to-vi...

Background Adolescents engage in various combinations (typologies) of physical activity and sedentary behaviors, which impact their health and wellbeing in different ways. As such, there is a need to understand the factors that may inhibit or facilitate engagement in combinations of activity-related behaviors to help inform effective intervention s...

Research has documented the decline in children’s independent mobility (CIM) globally. CIM is a measure of the level of a child’s freedom to move about his or her local neighbourhood without direct adult supervision. This paper explores the effectiveness of three intervention programmes to change travel behaviours of children to and from school in...

Disadvantaged communities tend to have poorer early childhood development outcomes. Access to safe, secure, and stable housing is a well-known social determinant of health but there is a need to examine key features of neighbourhood housing that reduce early childhood development inequities. The 2012 Australian Early Development Census (AEDC), a po...

Background Clusters of adolescents differentiated by patterns of physical activity and sedentary behavior (activity-related typologies) are common. Understanding both the characteristics of adolescents and modifiable correlates of these typologies, can help to develop interventions for those most at risk. This systematic review aimed to synthesize...

The community (or neighbourhood) is seen as a potential point of intervention for improving early childhood development outcomes through place-based approaches targeting all children. Yet there are insufficient robust data to guide policy and practice. Developing community factors for early childhood development is one way to facilitate more inform...

Background: Optimal mental health in early childhood is key to later mental health, physical health, education, and social outcomes; yet, children facing disadvantage tend to have worse mental health and fewer opportunities to develop this foundation. An emerging body of research shows that neighborhoods provide important opportunities for the dev...

Objectives: To identify typologies of activity-related behaviours and demographic characteristics of these typologies among Australian adolescents. Design: Cross-sectional study of 473 Secondary School students (41.4% boys, mean age 14.95±1.61 years) conducted in 2014-15. Methods: Active travel to school, sport participation, leisure-time sede...

The advertising of unhealthy food and beverages forms an important component of obesogenic environments. Such marketing to children is a key health determinant because of its impact on dietary preference and food purchasing behaviour. The location of outdoor advertising is important in exploring obesogenic environments and children's neighbourhoods...

CITY KNOW-HOW Human health and planetary health are both influenced by city lifestyles, city leadership, and city development. For both, worrying trends are leading to increasing concern. It is imperative that both become core foci in urban policy. Changing the trajectory will require concerted action. The journal Cities & Health journal is dedicat...

Social infrastructure requires a consistent and measurable definition and more evidence is needed to demonstrate why it is important to health, wellbeing and the liveability of a community. In this paper, social infrastructure is defined as life-long social service needs related to health, education, early childhood, community support, community de...

Public open spaces (POS) are key neighbourhood destinations shown to confer numerous physical and mental health benefits. The amount and spatial distribution of POS throughout cities are guided by urban planning policies and standards. However, empirical evidence is not generally used to create POS standards. Developing and testing POS indices asso...

Introduction Healthy childhood development in the early years is critical for later adult health and well-being. Early childhood development (ECD) research has focused primarily on individual, family and school factors, but largely ignored community factors. The Kids in Communities Study (KiCS) will test and investigate community-level influences o...

Global obesity prevalence has risen dramatically over the past 30 years in both adults and children. 1 This presents a major public health challenge because of its contribution to chronic disease and inequities in the distribution of obesity within populations. 1 Obesity arises from the energy imbalance associated with dietary intake, physical acti...

Objectives: Although the harms of tobacco use are widely accepted, few studies have examined the relationship between access to tobacco outlets and hospital admissions. This study aimed to examine the relationship between neighbourhood access to tobacco outlets, smoking and hospital admissions and self-reported morbidity. Methods: Responses as t...

Objective: To investigate the effect of sibling age, gender and dog ownership on children's independent mobility and how this varies according to the destination visited. Methods: Parents reported whether their child had an older sibling; if the child and older sibling were of the same gender; the number of older siblings; if they owned a dog; a...

This study examined whether the association of psychological distress with area-level socio-economic status (SES) was moderated by the area and attractiveness of local green space. As expected, the odds of higher psychological distress was higher in residents in lower SES areas than those in higher SES areas. However, our results were inconclusive...

The street network underpins the walkability of local neighborhoods. We examined whether two street network measures (intersection density and street integration from space syntax) were independently associated with walking for transport (WT); and, to what extent the relationship of street integration with WT may be explained by the presence of des...

Healthy child development is determined by a combination of physical, social, family, individual, and environmental factors. Thus far, the majority of child development research has focused on the influence of individual, family and school environments, and largely ignored the neighborhood context despite the increasing policy interest. Yet given t...

With not much to do in their neighborhood, youth may spend more time in the home engaged in screen-based activities. Screen time data from 2,790 youth in the Western Australian Health and Wellbeing Survey were linked to objectively measured count of types of neighborhood “services,” “convenience goods,” “public open space,” and “youth-related” dest...

Background Using a health and wellbeing lens, ‘liveable’ communities are viewed as safe, attractive, socially cohesive and inclusive, and environmentally sustainable, with affordable and diverse housing linked via public transport, walking, and cycling to employment, education, public open space, local shops, health and community services, and leis...

Employment is a well-known social determinant of health and wellbeing and important for the liveability of a region. Yet, spatial data are rarely used to understand barriers and facilitators of accessing employment within a city. Therefore it remains challenging to plan cities that provide equitable opportunities for urban job seekers. This paper s...

Public open spaces such as parks and green spaces are key built environment elements within neighbourhoods for encouraging a variety of physical activity behaviours. Over the past decade, there has been a burgeoning number of active living research studies examining the influence of public open space on physical activity. However, the evidence show...

Relationships between context-specific measures of the physical and social environment and children's independent mobility to neighborhood destination types were examined. Parents in RESIDE's 4th survey reported whether their child (8-15 years; n=181) was allowed to travel without an adult to school, friend's house, park and local shop. Objective p...

The bulk of child development research has focused on the influence of family and school environments, and has largely ignored the neighbourhood context. Yet given that neighbourhoods are where children spend most time outside of home and school, it is plausible the physical design of neighbourhoods, including access to local amenities, impact on c...

There is growing interest from policy-makers, practitioners, and academics alike in creating indicators of the built environment to measure progress towards achieving a wide range of policy outcomes, including enhanced health and wellbeing. Public open space (POS) is a built environment feature that is important for health and wellbeing across the...

Aim: Liveable communities create the conditions to optimise health and wellbeing outcomes in residents by influencing various social determinants of health - for example, neighbourhood walkability and access to public transport, public open space, local amenities, and social and community facilities. This study will develop national liveability in...

Objective: Dog ownership is positively associated with children's physical activity. It is plausible that dog-facilitated activity rather than dog ownership per se encourages children's physical activity behaviors. We examined relationships between dog walking and children's physical activity, and outdoor play and independent mobility. Method: C...

Background Few studies have investigated associations between objectively measured crime and walking, and findings are mixed. One explanation for null or counterintuitive findings emerges from criminology studies, which indicate that the permeable street layouts and non-residential land uses that underpin walkable neighbourhoods are also associated...

Objective: Built environment attributes may be important determinants of physical activity. Greater street connectivity has been shown in several studies to be associated with adults' walking for transport (WFT). We examined the extent to which this association can be explained by the availability of utilitarian destinations. Methods: Adults (n=...

Evidence-based and replicable spatial indicators relevant to transport policy are needed to monitor pathways for health behaviours and outcomes and inform planning in this field. Yet, little is known about which indicators are most useful, what are meaningful geographic scales for applying spatial data, and how these relate to urban and transport p...

Variations in 'slope' (how steep or flat the ground is) may be good for health. As walking up hills is a physiologically vigorous physical activity and can contribute to weight control, greater neighbourhood slopes may provide a protective barrier to weight gain, and help prevent Type 2 diabetes onset. We explored whether living in 'hilly' neighbou...

We explored the impact of neighborhood walkability on young adults, early-middle adults, middle-aged adults, and older adults' walking across different neighborhood buffers. Participants completed the Western Australian Health and Wellbeing Surveillance System Survey (2003-2009) and were allocated a neighborhood walkability score at 200m, 400m, 800...

Studies repeatedly highlight associations between the built environment and physical activity, particularly walking. Fewer studies have examined associations with cardiometabolic risk factors, with associations with obesity inconsistent and scarce evidence examining associations with other cardiometabolic risk factors. We aim to investigate the ass...

Associations between access to local destinations and children’s independent mobility (IM) were examined. In 2007, 10- to 12-year-olds (n = 1,480) and their parents (n = 1,314) completed a survey. Children marked on a map the destinations they walked or cycled to (n = 1,132), and the availability of local destinations was assessed using Geographic...

The association between neighbourhood walkability and children's independent mobility using an ecological approach is relatively unexplored. In 2007, 1480 10- to 12-year-old children (and 1314 parents) attending low and high walkable schools across Perth, Western Australia, completed surveys. Objective built environment, social-cultural and individ...

This study investigated whether being driven to school was associated with lower weekday and weekend step counts, less active out-of-school leisure pursuits and more sedentary behavior. Boys aged 10-13 years (n=384) and girls aged 9-13 years (n=500) attending 25 Australian primary schools wore a pedometer and completed a travel diary for one week....

Introduction The built environment is increasingly recognised as being associated with health outcomes. Relationships between the built environment and health differ among age groups, especially between children and adults, but also between younger, mid-age and older adults. Yet few address differences across life stage groups within a single popul...

Objectives: We evaluated the accuracy of the Accusplit AH120 pedometer (built-in memory) for recording step counts of children during treadmill walking against (1) observer counted steps and (2) concurrently measured steps using the previously validated Yamax Digiwalker SW-700 pedometer. Design: This was a cross-sectional validation study perfor...

This study explored children's activity spaces. In 2007, children aged 10-12 years (n=1480) completed a survey and mapping activity, and wore a pedometer for seven days. Their parents completed a survey (n=1314). Over half traveled <25% of their 'neighborhood', defined as 800 m and 1600 m network buffers. More local destinations (boys β=-0.022; gir...

Active school transport (AST) has declined rapidly in recent decades. While many studies have examined walking, cycling to school has received very little attention. Correlates of cycling are likely to differ to those from walking and cycling enables AST from further distances. This study examined individual, social and environmental factors associ...

Efforts to increase the prevalence of children's active school transport require evidence to inform the development of comprehensive interventions. This study used a multilevel ecological framework to investigate individual, social, and environmental factors associated with walking to and from school among elementary school-aged children, stratifie...

b>Background : Schools are an ideal setting in which to involve children in research. Yet for investigators wishing to work in these settings, there are few method papers providing insights into working efficiently in this setting. Objective : The aim of this paper is to describe the five strategies used to increase response rates, data quality an...

Children who participate in regular physical activity obtain health benefits. Preliminary pedometer-based cut-points representing sufficient levels of physical activity among youth have been established; however limited evidence regarding correlates of achieving these cut-points exists. The purpose of this study was to identify correlates of pedome...

The impact of neighborhood walkability (based on street connectivity and traffic exposure) within 2 km of public primary schools on children regularly walking to school was examined. The most (n=13) and least walkable (n=12) schools were selected using a school-specific 'walkability' index and a cross sectional study undertaken of Year 5, 6 and 7 c...
