A place for play? The influence of the home physical environment on children's physical activity and sedentary behaviour.

The home environment is an important influence on the sedentary behaviour and physical activity of children, who have limited independent mobility and spend much of their time at home. This article reviews the current evidence regarding the influence of the home physical environment on the sedentary behaviour and physical activity of children aged 8–14 years. A literature search of peer reviewed articles published between 2005 and 2011 resulted in 38 observational studies (21 with activity outcomes, 23 with sedentary outcomes) and 11 experimental studies included in the review. The most commonly investigated behavioural outcomes were television watching and moderate to vigorous physical activity. Media equipment in the home and to a lesser extent the bedroom were positively associated with children’s sedentary behaviour. Physical activity equipment and the house and yard were not associated with physical activity, although environmental measures were exclusively self-reported. On the other hand, physical activity equipment was inversely associated with sedentary behaviours in half of studies. Observational studies that investigated the influence of the physical and social environment within the home space, found that the social environment, particularly the role of parents, was important. Experimental studies that changed the home physical environment by introducing a television limiting device successfully decreased television viewing, whereas the influence of introducing an active video game on activity outcomes was inconsistent. Results highlight that the home environment is an important influence on children’s sedentary behaviour and physical activity, about which much is still unknown. While changing or controlling the home physical environment shows promise for reducing screen based sedentary behaviour, further interventions are needed to understand the broader impact of these changes. Future studies should prioritise investigating the influence of the home physical environment, and its interaction with the social environment, on objectively measured sedentary time and home context specific behaviours, ideally including technologies that allow objective measures of the home space.

Effects of Find Thirty every day® Cross-Sectional Findings From a Western Australian Population-Wide Mass Media Campaign, 2008-2010

Background. Internationally, over the last four decades large-scale mass media campaigns have been delivered to promote physical activity and its associated health benefits. In 2002-2005, the first Western Australian statewide adult physical activity campaign Find Thirty. It’s Not a Big Exercise was launched. In 2007, a new iteration of the campaign was proposed with new objectives, executions, and tag line Find Thirty every day®. Purpose. This article reports on the population-level effects of the Find Thirty every day® campaign from 2008 to 2010, with a focus on changes in awareness, intention, and physical activity. Methods. Evaluation of the campaign involved pre- and posttest serial cross-sectional surveys. Baseline data were collected in May 2008, and subsequent surveys in 2009 and 2010. Samples sizes were as follows: baseline (n = 972), first follow-up (n = 938), and second follow-up (n = 937). Data were derived from self-reported responses to a random-sample computer-assisted telephone interview. Results. Total awareness increased from 30.4% at baseline to 48.5% at second follow-up. Total awareness was higher in women and low socioeconomic status adults. Intention was 21.0%, double that reported at baseline. There were positive significant changes from baseline to first follow-up across all four categories: walking, moderate, vigorous, and total physical activity. There also were positive significant changes for self-reported walking from baseline to second follow-up. Conclusion. Find Thirty every day® resulted in an increase in awareness, intention, walking, vigorous intensity, and total level of physical activity in priority target groups. Campaign effects should be further examined by subgroups to identify the most receptive population segments.

The Dynamic Family Home: a qualitative exploration of physical environmental influences on children’s sedentary behaviour and physical activity within the home space

BackgroundRecent changes in home physical environments, such as decreasing outdoor space and increasing electronic media, may negatively affect health by facilitating sedentariness and reducing physical activity. As children spend much of their time at home they are particularly vulnerable. This study qualitatively explored family perceptions of physical environmental influences on sedentary behaviour and physical activity within the home space.MethodsHome based interviews were conducted with 28 families with children aged 9–13 years (total n = 74 individuals), living in Perth, Australia. Families were stratified by socioeconomic status and selected to provide variation in housing. Qualitative methods included a family interview, observation and home tour where families guided the researcher through their home, enabling discussion while in the physical home space. Audio recordings were transcribed verbatim and thematically analysed.ResultsEmergent themes related to children’s sedentariness and physical activity included overall size, space and design of the home; allocation of home space; equipment within the home space; perceived safety of the home space; and the changing nature of the home space. Families reported that children’s activity options were limited when houses and yards were small. In larger homes, multiple indoor living rooms usually housed additional sedentary entertainment options, although parents reported that open plan home layouts could facilitate monitoring of children’s electronic media use. Most families reported changing the allocation and contents of their home space in response to changing priorities and circumstances.ConclusionsThe physical home environment can enhance or limit opportunities for children’s sedentary behaviour and physical activity. However, the home space is a dynamic ecological setting that is amenable to change and is largely shaped by the family living within it, thus differentiating it from other settings. While size and space were considered important, how families prioritise the use of their home space and overcome the challenges posed by the physical environment may be of equal or greater importance in establishing supportive home environments. Further research is required to tease out how physical, social and individual factors interact within the family home space to influence children’s sedentary behaviour and physical activity at home.

Influence of the day care, home and neighbourhood environment on young children's physical activity and health: protocol for the PLAYCE observational study

Introduction The early years are a critical period in a childs health and development, yet most preschool children fail to meet physical activity guidelines. Outside of the home and neighbourhood, children spend a large proportion of time within early childhood education and care (ECEC) services such as long day care. Research is required to determine how the design of day care outdoor (and indoor) spaces provides opportunities or constraints for physical activity. A significant evidence gap surrounds what objectively measured attributes of the home and neighbourhood environment influence preschoolers’ physical activity. The PLAY Spaces & Environments for Childrens Physical Activity (PLAYCE) study will empirically investigate the relative and cumulative influence of the day care, home and neighbourhood environment on preschoolers’ physical activity. Methods and analysis The PLAYCE study is a cross-sectional observational study (April 2015 to April 2018) of 2400 children aged 2–5 years attending long day care in metropolitan Perth, Western Australia. Accelerometers will measure physical activity with indoor physical activity measured using radio frequency identification. Global positioning systems will be used to determine outdoor location of physical activity around the home and neighbourhood for a subsample (n=310). The day care environment will be objectively measured using a validated audit tool. Other potential individual, social and physical environmental influences on preschoolers’ physical activity will be collected by geographic information systems measures, parent and day care educator surveys. Ethics and dissemination Ethical approval has been granted by The University of Western Australia Human Ethics Research Committee, approval number RA/4/1/7417. Findings will be published in international peer-reviewed journals and presented at international conferences. Key findings will be disseminated to stakeholders, collaborators, policymakers and practitioners working in the ECEC sector. Day care centre directors and parents will be given a summary report of the key findings.

Capturing the geography of children’s active and sedentary behaviours at home: the HomeSPACE measurement tool

ABSTRACT Children spend much of their time at home, indoors and sedentary. This study reports on the development, exploratory factor analysis, validity and reliability of the HomeSPACE Instrument. The instrument assesses features of the home physical environment that influence children’s sedentary behaviour and physical activity, and the family influences that create this environment. The space and equipment audit achieved good to excellent criterion validity and test-retest reliability for equipment, outdoor features and home design measures (Study 1, n = 36 parents). Family influence scales showed acceptable internal consistency and test-retest reliability (Study 2, n = 96 parents). Factor analysis highlighted fifteen scales to assess the importance, preferences and supportiveness of the home environment for activity. The HomeSPACE Instrument extends previous tools to provide a valid and reliable assessment of home influences on children’s sedentary behaviour and physical activity, that is adaptable for varying home physical environments.
