Where are the alcohol advertising hotspots near schools?

ISSUE ADDRESSED: Physically locating liquor stores near schools can strongly influence the chances of youth accessing and consuming alcohol, and may also increase children's exposure to alcohol advertising. Investigating the association between the presence of a liquor store near a school and the prevalence of outdoor alcohol advertising is crucial from a policy perspective, as it can inform future regulations on the placement of liquor stores and outdoor advertising near educational institutions. METHODS: All outdoor alcohol advertising within a 500 m radius (audit zone) of 64 randomly selected schools from local government areas across metropolitan Perth was identified by direct observation; recording the size, setting, location and content of each advertisement. Results were compared based on whether the school audit zone contained a liquor store or not. RESULTS: Over half (n = 36, 56%) of all school audit zones had at least one alcohol advertisement, with an average number of 5.9 alcohol advertisements per zone (SD = 10.2). The majority (97.9%) of advertisements were in the 38 audit zones containing a liquor store (average = 9.7, SD = 11.9 per zone), compared to zones without a liquor store (average = .3, SD = .7 per zone). CONCLUSIONS: Perth school zones containing a liquor store in their 500 m radius had, on average, 30 times more outdoor alcohol advertising, compared with school zones without a nearby liquor store. SO WHAT?: The siting of liquor stores and the display of alcohol advertisements around educational settings require combined policy, planning and public health approaches to mitigate children's exposure to alcohol marketing, especially during school transit.

Young people's alcohol use in and around water: A scoping review of the literature.

ISSUES: The surrounding social and commercial context, including alcohol advertising, heavily influences alcohol consumption. Alcohol use is a major risk factor for both fatal and non-fatal drowning, particularly for young people. APPROACH: We conducted a scoping review to explore the peer-reviewed literature on the use of alcohol by young people (aged 15-34 years) in the context of aquatic environments. Five electronic academic databases were searched for English-language studies conducted in high-income countries and published in the last 15 years (since 2008). The MetaQAT framework was used to assess methodological quality of included studies. KEY FINDINGS: The review included a total of 24 studies, including those addressing the prevalence of and/or risk factors for alcohol use in aquatic environments among young people (n = 13); the epidemiology of alcohol-related unintentional drowning in young people (n = 9); and interventions to reduce alcohol-related harm around water (n = 3). Findings suggest that young people commonly consume alcohol around water, particularly young men. We found multiple influences on this behaviour, including the perception of risk, location of aquatic activity and presence of others, particularly peers. IMPLICATIONS: Understanding the literature addressing alcohol use around water among young people will assist in identifying and setting priorities for drowning prevention, including the need to mitigate the effects of alcohol advertising which promotes drinking in and around water. CONCLUSION: There is a clear imperative to address the use of alcohol by young people in aquatic environments. These findings have key implications for public health policy, advocacy and practice.

The park physical activity questionnaire (Park-PAQ): A reliable measurement tool for park-based and total physical activity.

BACKGROUND: Few studies have explicitly quantified the proportion of park-based physical activity to park users' overall physical activity levels. Population studies need new context-specific physical activity measurement tools to achieve this. The objective of this study was to develop a reliable measure of self-reported park use and physical activity undertaken within and outside of parks to determine the contribution that park-based physical activity makes to overall physical activity levels. METHODS: A test-retest reliability study (n = 104) was conducted using the Park Physical Activity Questionnaire (Park-PAQ), an instrument based on the Active Australia Survey. Park-PAQ items captured the frequency and duration of walking for recreation or exercise, walking for transport, moderate and vigorous physical activity and strength, conditioning and balance activities done in parks and elsewhere. RESULTS: Recall of doing any walking for recreation (kappa = 0.649, p < 0.001) and any vigorous physical activity (kappa = 0.772, p < 0.001) was 'substantial', recall of doing any moderate physical activity (kappa = 0.553, p < 0.001) was 'moderate/acceptable', and recall of any walking for transport (kappa = 0.840, p < 0.001) 'near perfect'. Recall of the time spent walking for recreation in parks (ICC = 0.928, p < 0.001) was 'near perfect', whilst recall of time spent doing moderate activity in parks (ICC = 0.925, p < 0.001) and vigorous activity in parks (ICC = 0.962, p < 0.001) was 'near perfect'. Time spent walking for transport in a park (ICC = 0.200, p = 0.056) showed 'poor' agreement. Repeatability of the usual level of park use was 'substantial' (kappa = 0.744). CONCLUSIONS: The Park-PAQ reliably measures six domains of physical activity and quantifies the proportion of physical activity done in parks as a proportion of total physical activity. The Park-PAQ, used alone or embedded into park or physical activity surveys, will reliably capture context-specific activities that will optimise population level physical activity interventions, park programming and park management and design.

The architecture of mental health: identifying the combination of apartment building design requirements for positive mental health outcomes.

Background: Housing quality is a crucial determinant of mental health. While the construction of high-rise buildings is a popular policy strategy for accommodating population growth in cities, there is considerable debate about the health consequences of living in poorly designed apartments. Drawing on three Australian state government apartment design policies introduced to improve apartment design quality, this study aimed to identify the combination of design requirements that were optimally supportive of positive mental health. Methods: K-means cluster analyses identified groups of buildings (n = 172) that were homogenous in their implementation of a mix of n = 80 measured design requirements. Positive mental health was measured using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Linear mixed-effects models controlling for demographic characteristics, self-selection factors and clustering of participants within buildings compared residents in the different clusters. Findings: Residents in the "high policy performance buildings", characterised by having a greater implementation of n = 29 design requirements across nine design elements, had significantly higher (+1.96 points) WEMWBS scores compared with residents in the "low policy performance buildings". Interpretation: This study is the first to empirically identify a mix of policy-specific architecture design requirements that are associated with positive mental health in apartment residents. These findings provide vital empirical evidence to inform national and international apartment and high-rise housing policies, and design instruments and practices to protect people's health in apartment dwellings.

Policy relevant health related liveability indicator datasets for addresses in Australia's 21 largest cities.

Measuring and monitoring the spatial distribution of liveability is crucial to ensure that implemented urban and transport planning decisions support health and wellbeing. Spatial liveability indicators can be used to ensure these decisions are effective, equitable and tracked across time. The 2018 Australian National Liveability Study datasets comprise a suite of policy-relevant health-related spatial indicators of local neighbourhood liveability and amenity access estimated for residential address points and administrative areas across Australia's 21 most populous cities. The indicators and measures encompass access to community and health services, social infrastructure, employment, food, housing, public open space, transportation, walkability and overall liveability. This national 'baseline' liveability indicators dataset for residential address points and areas can be further linked with surveys containing geocoded participant locations, as well as Census data for areas from the Australian Statistical Geography Standard. The datasets will be of interest to planners, policy makers and researchers interested in modelling and mapping the spatial distribution of urban environmental exposures and their relationship with health and other outcomes.

The community food environment and its association with diet, health or weight status in Australia: A systematic review with recommendations for future research.

ISSUE ADDRESSED: This study systematically reviewed Australian literature to determine if an association exists between geospatial exposure to food outlets and diet, health or weight status. Recommendations for future research are provided. METHODS: A systematic literature search was conducted in December 2021 using CINAHL Plus, PubMed and Web of Science databases. Data were extracted, as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study quality was assessed using an eight-item checklist. A descriptive synthesis of study characteristics and findings was carried out, stratified via study outcomes. RESULTS: Of the 36 included articles, the majority were from Victoria (n = 19), involving adult participants (n = 30) and cross-sectional in design (n = 27). Overall, associations were mainly null (nonsignificant) for diet (80%), weight status (75%) and health outcomes (90%). Significant findings were mixed with no positive trend with study quality. CONCLUSIONS: Six recommendations are suggested to address current knowledge gaps and limitations in the Australian evidence base: (1) Conduct research on different populations; (2) Employ robust study designs that can test the impact of change over time; (3) Improve the accuracy of food outlet data sources; (4) Improve food outlet geospatial exposure measures; (5) Improve measurement of outcome variables; and (6) Incorporate theoretical models into study design and data analysis. SO WHAT?: Improving the quality and consistency of research will be critical to informing locally relevant policy. Despite the present limitations in the evidence base, it is reasonable to assume that decisions to purchase and consume food are driven by availability and access. Thus, policy and planning aimed at improving the overall "healthiness" of the community food environment by increasing access to healthy food outlets is warranted to ensure that healthy options are easier choice for all.

Would you like fries with that? Investigating fast-food outlet availability near schools in Perth, Western Australia.

ISSUE ADDRESSED: Locating fast-food outlets near schools is a potential public health risk to schoolchildren, given the easy access and repeated exposure to energy-dense, nutrient-poor foods they provide. Fast-food outlet availability near schools has not been previously investigated in Perth, Western Australia. This study aimed to quantify fast-food outlet availability near Perth schools and determine whether differences in area-level disadvantage and school type exist. METHODS: Fast-food outlet locations were sourced from Perth Local Governments in 2018/2019. All Perth Primary (n = 454), Secondary (n = 107) and K-12 (n = 94) schools were assigned an area-level disadvantage decile ranking based on the Australian Bureau of Statistics Socio-Economic Index for Areas (SEIFA). Regression models assessed whether fast-food outlet availability within 400 m, 800 m and 1 km of schools differed by school type (ie, Primary/Secondary/K-12) or SEIFA. RESULTS: Secondary schools were significantly more likely than Primary and K-12 schools to have a higher presence and density of fast-food outlets and the "Top 4" fast-food outlet chains (McDonalds, Hungry Jacks, KFC and Red Rooster) nearby. Schools located in low socio-economic status (SES) areas had a significantly higher density of fast-food outlets within 400 m, and "Top 4" fast-food outlet chains within 400 m and 1 km, than schools located in high SES area. CONCLUSIONS: Perth schools are surrounded by fast-food outlets with densities significantly higher around secondary schools and schools located in lower SES areas. SO WHAT?: Policies and regulations aimed at reducing fast-food outlets near schools is an essential strategy to improve dietary intakes and reduce obesity in schoolchildren.

Grand designs for design policy: Associations between apartment policy standards, perceptions of good design and mental wellbeing.

Comprehensive apartment design policies have been legislated by Australian state governments to address concerns about poor design in residential buildings. These policies aim to improve apartment design and promote good health. This study examined whether: (1) residents living in apartments that implemented more minimum design requirements perceived better apartment design and amenity; and (2) increased implementation of minimum requirements and better perceptions of design were associated with positive mental wellbeing. Apartment complexes (n = 114, built 2006-2016) were sampled from Sydney, Perth, and Melbourne. Building plans and elevations were used to measure and score apartments for their implementation of 96 quantifiable policy-specific requirements and residents (n = 1072) completed a self-report survey on their apartment design and health. Multi-level linear regression models were used to account for clustered data. Residents in apartments with greater implementation of requirements for solar and daylight, indoor space, private open space, communal space and parking had more positive perceptions of their apartment in terms of natural light and winter thermal comfort, indoor space and layout, private open space, communal area quality, and parking, respectively (all p < 0.05). Perceptions of natural ventilation, summer thermal comfort, indoor space, and communal area quality were independently associated with positive mental wellbeing (all p < 0.05), but the objective implementation scores had no direct association. When implemented as intended, minimum requirements had a positive impact on perceptions of design, which were associated with mental wellbeing. The study underscores the importance of planning instruments and design review processes that increase industry uptake of minimum policy standards.

Spatial and socioeconomic inequities in liveability in Australia's 21 largest cities: Does city size matter?

Spatial and area-level socioeconomic variation in urban liveability (access to social infrastructure, public transport, open space, healthy food choices, local employment, street connectivity, dwelling density, and housing affordability) was examined and mapped across 39,967 residential statistical areas in Australia's metropolitan (n = 7) and largest regional cities (n = 14). Urban liveability varied spatially, with inner-city areas more liveable than outer suburbs. Disadvantaged areas in larger metropolitan cities were less liveable than advantaged areas, but this pattern was reversed in smaller cities. Local data could inform policies to redress inequities, including those designed to avoid disadvantage being suburbanised as cities grow and gentrify.

Measuring the high life: A method for assessing apartment design policy implementation.

This paper introduces a comprehensive method to measure the implementation of residential apartment design policies in Australia. It describes a protocol for extracting and measuring potentially health-enhancing policy-specific design requirements derived from three current residential apartment design policies in Sydney, Melbourne and Perth. These requirements focus on ten key design elements: (1) solar access, (2) natural ventilation, (3) private open space, (4) communal open space, (5) circulation spaces, (6) acoustic privacy, (7) outlook and (8) visual privacy, (9) bicycle and car parking and (10) apartment mix. This paper also describes the computation of scores to quantify the levels of on-ground implementation of the design requirements and compliance with the policies. The method will allow researchers to objectively quantify, benchmark and assess the uptake of apartment policy in apartment design and construction to inform future policy development. • Measurements were developed to systematically assess apartment buildings for their implementation of specific design requirements stipulated by State Government design policies. • Policy implementation was defined as the degree to which the apartment buildings adhered to the requirements outlined by the apartment design policies. A scoring system was developed to quantify policy implementation at both the apartment and building levels. • This method can be replicated to allow researchers to objectively quantify, benchmark and assess the uptake of apartment policy in apartment design and construction to inform future policy development.

Does fast-food outlet density differ by area-level disadvantage in metropolitan Perth, Western Australia?

ISSUE ADDRESSED: Socio-economic spatial patterning of fast-food outlets can result in disparities in the availability and access of food across geographic areas, contributing to health inequalities. This study investigated whether area-level socio-economic disparities exist in fast-food availability across the Perth metropolitan region of Western Australia. METHODS: Fast-food outlet locations were sourced from Perth Local Governments in 2018/2019. All Perth suburbs (n = 328) were allocated a decile ranking based on the Australian Bureau of Statistics Socio-Economic Index for Areas with decile 1 indicating relatively greater disadvantage and decile 10 indicating a relative lack of disadvantage. Zero-inflated negative binomial regression models, adjusted for suburb area and population density, were used to investigate the association between area-level disadvantage decile and availability of fast-food outlets. RESULTS: A socio-economic gradient was identified; for every unit increase in disadvantage decile (ie a reduction in relative disadvantage), the count of fast-food outlets decreased by 6% (P < .01), and the count of the "top ranking" fast-food chains (ie McDonalds, KFC, Hungry Jacks and Red Rooster) decreased by 10% (P < .001). CONCLUSIONS: Consistent with evidence internationally and from within Australia, socio-economic spatial patterning of fast-food outlet availability was shown to exist in Perth, with greater fast-food availability in areas with more relative socio-economic disadvantage. SO WHAT?: To address health inequities associated with fast-food consumption, policy and practice changes are needed that manage fast-food outlet proliferation in areas of greater socio-economic disadvantage.

Children's exposure to outdoor food advertising near primary and secondary schools in Australia.

ISSUE ADDRESSED: Previous research has highlighted children's frequent exposure to advertisements of unhealthy food and beverages on television. However, the food industry is increasingly utilising non-broadcast channels such as outdoor advertising (eg billboards, bus shelters, shop fronts) for product marketing. Few studies have investigated children's exposure to outdoor food advertising around primary and secondary schools. This study aimed to quantify the presence and content of outdoor food advertisements within a 500 m radius of primary and secondary schools in Perth, Western Australia. METHODS: A cross-sectional design was used to capture outdoor advertisements within a 500 m radial buffer around the school boundary. The INFORMAS protocol for monitoring outdoor advertising around child-serving institutions was used. Sixty-four primary and secondary schools in Perth, Australia, were selected using random sampling within socio-economic and population density strata. RESULTS: In total, 5636 outdoor advertisements were identified within a 500 m radius of all 64 schools combined and 30% were for food. Of the 1708 food advertisements, 74% were for unhealthy (non-core) food. The most frequently advertised food products were alcohol, fast food and sugar-sweetened beverages. Only 8% of food advertisements featured a healthy product. The majority of schools (75%) had at least one food advertisement within 500 m (mean 36, range 3-190). Schools in lower socio-economic areas had more food advertisements and a significantly higher proportion of unhealthy food advertisements within 250 m. CONCLUSION: Outdoor advertising around schools constitutes a potential frequent source of children's exposure to unhealthy food and alcohol advertising. SO WHAT?: Policy interventions restricting the content of outdoor food advertising near schools are needed.

Association between food-outlet availability near secondary schools and junk-food purchasing among Australian adolescents.

OBJECTIVES: We sought to investigate the association between food-outlet availability near Australian secondary schools and frequency of Australian students' discretionary food purchases. METHODS: Secondary-school students in Perth (Western Australia) reported the frequency of their discretionary food purchases from food outlets near their school (17 schools, n = 2389 students grades 7-12, ages 12-17 y). Food-outlet availability was sourced from local governments, then geocoded. A mixed-effects model was used in analyses. RESULTS: Almost half of students (45%) purchased discretionary foods from food outlets near their secondary school at least weekly. Only the density of top-ranking fast-food chain outlets near secondary schools was associated with a significant increase in the frequency of discretionary food purchases. CONCLUSIONS: Availability of major fast-food chains near Australian secondary schools appears to be a key driver of Australian students' discretionary food purchasing. Restricting these outlets near schools may help reduce adolescents' discretionary food intake.

Exploring the potential for planning support systems to bridge the research-translation gap between public health and urban planning.

BACKGROUND: There is consensus that planning professionals need clearer guidance on the features that are likely to produce optimal community-wide health benefits. However, much of this evidence resides in academic literature and not in tools accessible to the diverse group of professionals shaping our cities. Incorporating health-related metrics into the planning support systems (PSS) provides an opportunity to apply empirical evidence on built environment relationships with health-related outcomes to inform real-world land use and transportation planning decisions. This paper explores the role of planning support systems (PSS) to facilitate the translation and application of health evidence into urban planning and design practices to create healthy, liveable communities. METHODS: A review of PSS software and a literature review of studies featuring a PSS modelling built environmental features and health impact assessment for designing and creating healthy urban areas was undertaken. Customising existing software, a health impact PSS (the Urban Health Check) was then piloted with a real-world planning application to evaluate the usefulness and benefits of a health impact PSS for demonstrating and communicating potential health impacts of design scenarios in planning practice. RESULTS: Eleven PSS software applications were identified, of which three were identified as having the capability to undertake health impact analyses. Three studies met the inclusion criteria of presenting a planning support system customised to support health impact assessment with health impacts modelled or estimated due to changes to the built environment. Evaluation results indicated the Urban Health Check PSS helped in four key areas: visualisation of how the neighbourhood would change in response to a proposed plan; understanding how a plan could benefit the community; Communicate and improve understanding health of planning and design decisions that positively impact health outcomes. CONCLUSIONS: The use of health-impact PSS have the potential to be transformative for the translation and application of health evidence into planning policy and practice, providing those responsible for the policy and practice of designing and creating our communities with access to quantifiable, evidence-based information about how their decisions might impact community health.

Exposure to unhealthy food and beverage advertising during the school commute in Australia.

BACKGROUND: Food marketing exposure has the potential to influence children's dietary behaviours and health status, however, few studies have identified how 'obesogenic' the outdoor food marketing environment is along public transport (bus and/or train) or walking routes that children take to school. METHODS: Audits of all outdoor advertisements present along likely train, bus and walking routes to 24 secondary schools (ie, 3 routes per school, 72 routes total) were conducted in Perth, Western Australia (WA). The size, content, type and setting of each advertisement were recorded in accordance with the International Network for Food and Obesity/non-communicable diseases Research, Monitoring and Action Support protocol for monitoring outdoor advertising. RESULTS: Of the 4016 total advertisements observed, almost half were for food (n=1754, 44%) and of these, 80% (n=1397) advertised discretionary (non-core) foods, and 8% (n=138) advertised healthy (core) foods. On average, commuting to school by train, bus and walking exposed Perth schoolchildren to 37.1, 22 and 4.5 discretionary (non-core) food ads per one-way trip to school, respectively. CONCLUSIONS: Children living in Perth, WA experience a high level of exposure to unhealthy outdoor food advertisements during the school commute. Policies which restrict the placement and content of outdoor advertising, could be a useful strategy in the fight against childhood obesity.

Food Outlets Dietary Risk (FODR) assessment tool: study protocol for assessing the public health nutrition risks of community food environments.

BACKGROUND: Availability and accessibility of nutritious foods can vary according to the food outlets present within a neighbourhood or community. There is increasing evidence that community food environments influence food choice, diet and the risk of diet-related chronic disease, however contemporary community food environments assessments (e.g. unhealthy fast food outlets versus healthy supermarkets or fruit and vegetable shops) may be too simplistic to accurately summarise the complexities of their impacts on food choice. This study protocol describes the development of the Food Outlets Dietary Risk (FODR) assessment tool for use by local government in Perth, Western Australia. METHODS: Similar to food safety risk assessment, the FODR assessment tool rates the potential harmful public health nutrition impact of food outlets by identifying and characterising the issues, and assessing the risk of exposure. Scores are attributed to six public health nutrition attributes: 1) availability of nutrient-poor foods; 2) availability of nutritious foods; 3) acceptability and appeal; 4) accessibility; 5) type of business operation; and 6) complex food outlet considerations. Food retail outlets are then classified as having a low, medium, high or very high dietary risk based on their total score. DISCUSSION: A local government administered tool to rate the public health nutrition risk of food outlets requires data which can be collected during routine assessments or sourced from the internet. The ongoing categorical classification of foods available within food outlets as either unhealthy or nutritious will require nutrition scientists' input. An objective risk assessment of the dietary impact of food retail outlets can guide local government planning, policies and interventions to create supportive community food environments. It is intended that locally relevant data can be sourced throughout Australia and in other countries to apply the local context to the FODR assessment tool. Utility and acceptability of the tool will be tested, and consultation with environmental health officers and public health practitioners will inform future iterations.

Do Changes in the Local Food Environment Within New Residential Developments Influence the Diets of Residents? Longitudinal Results from RESIDE.

Background: There is limited longitudinal evidence supporting a link between food outlet locations and dietary outcomes to inform policy and urban planning. This study examined how longitudinal changes in the local food environment within new residential developments influenced changes in adult dietary intake. Methods: Adult participant data (n = 3223 person-observations) were sourced from the RESIDential Environments (RESIDE) project across three time points between 2004 to 2012 in Perth, Western Australia. Fixed effects regression estimated the relationship between change in spatial exposure to the local food environment, individual behaviours and perceptions of the local food environment with dietary outcome variables (healthy diet score, unhealthy diet score, diet quality score and fruit/vegetable intake). Results: An increase over time in the percentage of healthy food outlets around the home was significantly (p ≤ 0.05) associated with an increase in healthy diet scores and an increase in the distance from home to the nearest café restaurant was significantly (p ≤ 0.05) associated with an increase in diet quality scores. Conclusions: Modifying the local food environment by increasing the relative proportion of healthy food outlets around the home may support healthier dietary intake.

Over the limit? Testing non-linear associations between alcohol outlets and young adults' alcohol consumption.

INTRODUCTION AND AIMS: By specifying a threshold at which the number of liquor licences has the most impact on local populations, authorities can work to restrict licence approvals and help prevent alcohol-related harm. DESIGN AND METHODS: Raine Study Generation 2 participants reported their alcohol intake at 22 years (n = 843) and liquor licences within 1600 m of participants' homes were mapped. Analyses examined associations between licences (all licences, on-premise licences, liquor stores) and alcohol intake (g ethanol per day). Two models were fitted: (i) forced a straight-line relationship; and (ii) allowed a curved relationship via restricted cubic splines. RESULTS: The straight-line and curved models showed significant relationships with all licences (P = 0.002 and P = 0.002 respectively) and on-premise licences (P = 0.006 and P = 0.01 respectively), but not liquor stores (P = 0.065 and P = 0.13 respectively). The straight-line model indicated that alcohol consumption increased, on average, by 0.15 g per day for each additional licence and 0.17 g per day for each additional on-premise licence. The curved model indicated that consumption increased by around 0.4 g per day for each additional licence from 0 to 10, but increases were negligible for additional licences beyond 10. The curved model provided a better overall fit to the data than the straight-line model (R2 9.52% vs. 9.18%), but the improvement in fit did not quite reach statistical significance (P = 0.08). The curvature was similar, but less pronounced for on-premise licences (R2 9.11% vs. 8.95%; P = 0.23). DISCUSSION AND CONCLUSIONS: Results suggest a possible saturation point at which additional licences have a smaller effect on the alcohol intake of 22-year-olds living in metropolitan Perth.

The influence of the local food environment on diet following residential relocation: longitudinal results from RESIDential Environments (RESIDE).

OBJECTIVE: To examine the associations of changes in the local food environment, individual behaviours and perceptions with changes in dietary intake, following relocation from an established neighbourhood to a new residential development. DESIGN: Spatial food environment exposure measures were generated relative to each participant's home address using the locations of food outlets at baseline (before moving house) and follow-up (1-2 years after relocation). Self-reported data on socio-demographics, self-selection, usual dietary intake, individual behaviours and perceptions of the local food environment were sourced from the RESIDential Environments (RESIDE) Project. Changes in spatial exposure measures, individual behaviours and perceptions with changes in dietary outcomes were examined using mixed linear models. SETTING: Perth, Western Australia, 2003-2007. PARTICIPANTS: Adults (n 1200) from the RESIDE Project. RESULTS: Moving to a new residential development with more convenience stores and café restaurants around the home was significantly associated with an increase in unhealthy food intake (ß = 0·049, 95 % CI 0·010, 0·089; ß = 0·020, 95 % CI 0·007, 0·033) and was partially mediated by individual behaviours and perceptions. A greater percentage of healthy food outlets around the home following relocation was significantly associated with an increase in healthy food (ß = 0·003, 95 % CI 0·001, 0·005) and fruit/vegetable intake (ß = 0·002, 95 % CI 0·001, 0·004). CONCLUSIONS: Policy and planning may influence dietary intakes by restricting the number of convenience stores and other unhealthy food outlets and increasing the relative percentage of healthy food outlets.

Positive HABITATS for physical activity: Examining use of parks and its contribution to physical activity levels in mid-to older-aged adults.

Studies of parks and physical activity rarely identify the actual spaces participants use. Using data from the HABITAT project, a longitudinal cohort of mid-to older-aged (40-70 years) respondents (n = 11,036) living in Brisbane Australia, this study examined (1) the demographic characteristics of users and non-users of parks; (2) the park used and the characteristics and features of the most popular reported spaces; and (3) the level of physical activity undertaken in the reported parks and whether users had higher total physical activity levels than non-users. Park use was significantly higher (p < 0.01) among dog walkers, couples (over 40) living with children, and those living in least disadvantaged areas. Regular park use was significantly higher among users of larger-sized neighbourhood and district-catchment parks. Park users were 35% more likely to meet the physical activity guidelines (OR = 1.35, 95%CI 1.21-1.50, p < 0.001) compared with those who indicated they did nto regularly use a park. The size of the park used was positively associated with participation in physical activity. Users of larger-sized parks spent more time doing vigorous activity and engaged in more activity sessions than non-users. Future data obtained from large populations, including spatial examination of the actual parks used and their characteristics, are essential to facilitate planning for park provision, optimising the use of these spaces for recreation and physical activity by mid-to older-aged adults, and creating healthy communities.
