城市建成环境如何影响老年人体力活动——模型构建与大连实证

针对建成环境与老年人体力活动关系研究中,较少定量刻画其与社会、心理要素交互作用的不足,本文构建了三者交互影响下的体力活动关系模型。研究发现：①老年人体力活动参与率整体不高,性别与家庭结构差异在活动表现形式上存在不同。②活动意向未能有效触发老年人体力活动,自我效能感是其重要参考因素;建成环境、社会资本对老年人体力活动的影响,由直接或间接通过自我效能感中介完成,心理健康作用则未显现。③家庭结构存在调节作用,建成环境单一要素对空巢老人体力活动的作用并不明显,但其对与子女共同居住老年人影响稳健。④社会资本是建成环境发挥空间干预老年人体力活动作用的重要前提;环境对公共健康的影响,更应采应取组合式干预策略。     

Effect of Scale on the Links between Walking and Urban Design

Studies of the relationship between walking and urban form consistently show that pedestrian‐friendly neighbourhoods encourage local walking. However, the geographic scale of measurement of the built environment for developing walkability indices and their relationship with different types of walking (e.g. for transport and recreation) has not been fully examined. In this study, objective measures of the built environment were developed at three geographic scales: suburb, census collection district, and 15 min walk neighbourhood for each participant. Walking for transport and recreation within the neighbourhood was measured using the Neighbourhood Physical Activity Questionnaire. The likelihood of walking at all (yes/no) and as recommended for health benefit (150 min per week) were assessed using logistic regression. The walkability index captured a strong positive relationship between urban form and walking for transport, but found no relationship at any scale for recreational walking. Participants walking for transport and living in high versus low walkable areas were 63% more likely to walk at the suburb scale (odds ratio 1.63; 95% confidence interval 1.22–2.18), twice as likely to walk at the census collection district scale, and nearly three times more likely to walk at the 15 min walk scale (odds ration 2.79; 95% confidence interval 2.09–3.73). The scale at which environmental data are measured influenced the strength of the relationship, showing that the neighbourhood 15 min from home was most predictive of transport walking. This has research and policy implications. Standardised scales across studies would both improve comparability of results and enhance understanding of the influences on walking.     

Changing recess geographies: children’s perceptions of a schoolyard renovation project promoting physical activity

ABSTRACT

Insights into children’s perceptions of their changing recess geographies are absent. The current paper provides qualitative evidence from 5 renewed schoolyards by investigating children’s perceptions of their new schoolyards. Ten focus groups (2 at each school) including go-along interviews were conducted, in total 57 4 to 8 graders (28 girls). The functional aspects of the altered child–environment relationship were assessed using Gibson’s concept of affordance, and changes in the meanings ascribed to the schoolyards by the children were studied by engaging a concept of place. Our findings reveal that schoolyards offering multiple potential affordances for physical activity seem more likely to engage a broader group of children in recess physical activity. The analysis, however, could point to a difference between places designed for children’s play and places where children actually play. To optimise actualisation of the potential affordances for recess physical activity, involving children throughout intervention planning and decision-making is crucial.     

The relationship between school ground design and intensity of physical activity

In this study, we investigated the relationship between school ground design and children's physical activity levels. In particular, we were interested in understanding the contribution of ‘green’ school ground design to physical activity levels. Data for this study were collected at an elementary school in Australia and in Canada. At each school, scans of Target Areas were completed to record the students' location and intensity of physical activity, based on the System for Observing Play and Leisure Activity in Youth (SOPLAY) (Australia: 23 scans, 6 Target Areas; Canada: 18 scans, 7 Target Areas). At both schools, the highest percentage of children present was engaged in vigorous physical activity on the manufactured equipment (42% of children/scan). Similarly, at both schools, the green area encouraged the highest percentage of children present to be engaged in moderate physical activity (47% of Australian children/scan, 51% of Canadian children/scan). The patterns of sedentary behavior differed slightly between countries. At the Australian school, the paved sporting courts (57%) and the paved canteen courtyard (50.5%) promoted the highest degree of sedentary play. At the Canadian school, the treed grassy berm (42%) and the treed concrete steps (43%) encouraged the highest percentage of sedentary behavior, followed by the open asphalt (34%). These results are also discussed in light of gender distribution. We conclude with a discussion of the design and cultural factors that influence children's physical activity on school grounds. We argue that if school grounds are to realize their potential to promote physical activity, they should include a greater diversity of design features and ‘green’ elements that engage children of varying interests and abilities in active play.     

New Zealand parents' understandings of the intergenerational decline in children's independent outdoor play and active travel

Children's independent mobility and physical activity levels are declining in Western countries. In the past 20 years New Zealand children's active travel (walking and cycling) has dropped on average from 130 to 72 minutes per week, and those travelling by car to school have increased from 31% to 58%. This paper describes parents' understandings of why 9–11-year-old primary school children in suburban Auckland are less likely to walk to school and play unsupervised outdoors than they were as children. Data gathered in focus groups show understandings range from proximate neighbourhood explanations to downstream impacts of a neoliberal policy context.     

Physical activity and rural young people's sense of place

This paper explores rural young people's perceptions of their local environments in relation to their experiences with physical activities through the use of visual methodologies. The main findings from map, photo and interview data from 13 rural young Australians included the importance of friends, family, and gender structures which are discussed in relation to developing a sense of place and how this shapes their experience in physical activities. The findings highlight the importance of sociocultural issues and raises questions regarding measuring physical activity prompting further qualitative research to inform sustainable and equitable physical activity promotion initiatives for rural young people.     

‘Walking … just walking’: how children and young people's everyday pedestrian practices matter

This paper considers the importance of walking for many children and young people's everyday lives, experiences and friendships. Drawing upon research with 175 9- to 16-year-olds living in new urban developments in south-east England, we highlight key characteristics of (daily, taken-for-granted, ostensibly aimless) walking practices, which were of constitutive importance in children and young people's friendships, communities and geographies. These practices were characteristically bounded, yet intense and circuitous. They were vivid, vital, loved, playful, social experiences yet also dismissed, with a shrug, as ‘just walking’. We argue that ‘everyday pedestrian practices’ (after Middleton 2010, 2011) like these require critical reflection upon chief social scientific theorisations of walking, particularly the large body of literature on children's independent mobility and the rich, multi-disciplinary line of work known as ‘new walking studies’. In arguing that these lines of work could be productively interrelated, we propound ‘just walking’—particularly the often-unremarked way it matters—as a kind of phenomenon which is sometimes done a disservice by chief lines of theory and practice in social and cultural geography.     

Building communities to promote physical activity: A multi-scale geographical analysis

The objective of this paper is to make explicit the linkages between specific characteristics in the urban built environment, moderate physical activity (in particular walking and cycling), and public health. The review will take place at three different scales — the region, the city and the city‐block. At all three scales, the main interest is placed on accessibility, with the recognition that if distances are short enough and there is high connectivity within neighbourhoods, people might be encouraged to walk or cycle. The paper will draw on urban built environment characteristics from a number of Michigan municipalities, including Detroit, Ann Arbor, Birmingham, East Lansing and Okemos.     

‘It’s fun in the legs’: children’s dwelling in garden trampolines

ABSTRACT

Physical activity is critical for children’s current and future health status. Understanding how children’s everyday outdoor environments encourage movement could help progress the health-environment debate. In response to this, and adopting a theoretical focus upon dwelling, skills and the haptic engagement, this qualitative case study explores 25 Danish 10–11-year-old children’s everyday use of garden trampolines. Three principal methods of data generation were employed in the fieldwork: photo-elicited interviews, group interviews and participant observation at children’s important outdoor places. Findings suggest that garden trampolines are important everyday outdoor places for children that – among other things – can spark a vigorous physical movement in abundantly meaningful and joyful ways. Further, findings indicate that trampolines are places of inexhaustible movement opportunities, which operate through haptic sensations, feelings of skilfulness and attunement, expansions of the range of motions available to the body, and interactions between children. Implications for future research and design are highlighted.     

Eyes on the alley: children’s appropriation of alley space in Riverdale,Toronto

ABSTRACT

Recent research suggests that numerous positive physical, cognitive, and social benefits can be derived from independent mobility and play agency amongst children, necessitating an understanding of how physical and social environments facilitate this development. This study involved parents, and children aged 9–13 from twelve households in the neighbourhood of Riverdale in Toronto. Using a mapping exercise to instigate discussion, participants were asked to describe where, how, and with whom play occurs in their neighbourhood. A reoccurring theme emerged amongst households that border a back alley where parents perceived this space as safer allowing them to grant greater independent mobility to their children and use this space as an intermediary tool to prepare their children for greater independence. For children, this space serves as one of creative appropriation, granting them access to more space and friends to play with. Situated within the context of age-friendly cities, this research identifies several socio-spatial qualities found in alleys that have the potential to contribute to the discussion of more inclusive city-building practice.     

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.

They say ‘kids with asthma don’t play sports’: geographies of asthma

ABSTRACT

Asthma is common among children worldwide. Although complex, physical activity participation is important in asthma management, to decrease chronic disease risk, and to facilitate healthy lifestyles for children. Team sport participation is a common way for children to engage in physical activity, but the spaces in which team sport is experienced can present social, physical and emotional challenges for children with asthma. This research aims to understand elements of the environment, broadly defined, that impact experiences of asthma in sport. In-depth interviews were conducted with youth team sport athletes (n?=?11) diagnosed with asthma, and youth team sport coaches (n?=?18) in Ontario, Canada. Results suggest that understanding the physical and social needs of child and youth athletes, and ensuring well-controlled asthma, are critical to maximizing performance and improving quality of life for asthmatic athletes.     

A visual ethnographic pilot study of school travel for families living with childhood disability

ABSTRACT

Children’s school transport has become a major research focus over the past 20 years, particularly within the fields of planning, transport geography, and children’s geographies. However, this work has rarely considered children living with disability. This article presents the pilot component of a visual ethnographic study about school transport within families living with childhood disability. It explains why we piloted the study, details the pilot process, and presents lessons learned from piloting the study with two families of children living with different mobility needs. The lessons largely concern the design of interview guides and the interviewing process, as well as the development of an adaptive photo kit to enable children’s independent participation. The article shows how piloting qualitative studies, particularly those involving disabled children, can be invaluable in terms of improving data collection technologies and logistics, as well as enabling inclusive participation.

‘They installed a speed bump’: children’s perceptions of traffic-calming measures around elementary schools

ABSTRACT

Growing scientific literature evaluates the impact of traffic-calming devices in terms of mobility behavior and safety, but little is known about their perceived impact from the point of view of children. Our study asks children about their perceptions of different traffic-calming measures around their schools. It draws on data gathered through eight focus groups, followed by walking tours with Grade 6 children (11–12 years old) (n?=?65, 27 boys, 38 girls) from elementary schools in different urban contexts in Quebec, Canada. Qualitative analysis of the discussions shows that (a) vehicle speed is the main perceived threat for participant children; (b) children are confident about the effectiveness of self-enforcing traffic-calming devices that reshape the street geometry; and (c) they are skeptical about the effectiveness of ‘informative’ measures such as signs and lines (marked pavement). Our findings inform public policy for a more effective promotion of walking and cycling among children.     

RURAL–URBAN SPATIAL INTERACTION IN THE GLOBAL SOUTH: LONG‐DISTANCE MOBILITY CHANGES,DESIRES AND RESTRICTIONS OVER TWO DECADES IN RURAL PHILIPPINES

The spatial interaction between rural and urban areas is intense in the Global South. While research into how this interaction influences livelihood opportunities is extensive, longitudinal identification and analysis of rural people's long‐distance mobility is rudimentary. This is problematic given the possible repercussions of a greater flow of people for transport system management (congestion, emissions, investments, social exclusion, etc.). Based on longitudinal survey data from 1990 to 2008/2009, this article addresses this gap by exploring how the long‐distance mobility behaviour of households and individuals has changed over a period of intensified rural–urban interaction in a rural Philippine area. The article furthermore addresses the individuals' mobility desires and restrictions related to long‐distance travel. The results indicate that both accessibility effects and effects related to information and communication technology (ICT), concentration of activities and opportunities towards major cities, age, labour market, and economic situation. Over time, particularly since improved accessibility conditions have enabled much faster travelling, more people have come to travel more frequently (although a suppressed demand is still present and inequalities are considerable) to more distant destinations, major cities in particular, for mainly social motives. A recent countertrend is evident, partly arising from mobile phones replacing physical movement. The increase in private vehicle ownership has so far been slow, so modal choice is still highly sustainable. Overall, the findings support core ideas derived from the new economic geography, but also notes, with earlier studies in transport geography, that travel time is a prime consideration.     

Children's Perceptions of the Use of Public Open Spaces for Active Free-play

Activity performed by children in their free-time may have a significant impact on overall physical activity levels, however, very little is known about the influences on children's active free-play. To examine the role and use of public open spaces, 132 children (6–12 years) from a selection of primary schools participated in small focus group interviews. Children reported that their use of public open spaces was influenced by a combination of intrapersonal, social and environmental factors including; the play equipment and facilities at local parks, lack of independent mobility, urban design features, presence of friends, and personal motivation.
