Previous studies have investigated the potential role of neighborhood walkability in reducing sedentary behavior. However, the majority of this research has been conducted in adults and Western developed countries. The purpose of the present study was to examine associations of neighborhood environmental attributes with sedentary time among older adults in Nigeria. Data from 353 randomly-selected community-dwelling older adults (60 years and above) in Maiduguri, Nigeria were analyzed. Perceived attributes of neighborhood environments and self-reported sedentary time were assessed using Nigerian-validated and reliable measures. Outcomes were weekly minutes of total sedentary time, minutes of sitting on a typical weekday, and minutes ...

Researchers investigating relationships between the neighbourhood environment and health first need to decide on the spatial extent of the neighbourhood they are interested in. This decision is an important and ongoing methodological challenge since different methods of defining and delineating neighbourhood boundaries can produce different results. This paper explores this issue in the context of a New Zealand-based study of the relationship between the built environment and multiple measures of physical activity. Geographic information systems were used to measure three built environment attributes—dwelling density, street connectivity, and neighbourhood destination accessibility—using seven different neighbourhood definitions (three administrative unit boundaries ...

The Contribution Of The Neighbourhood Environment To The Relationship Between Neighbourhood Disadvantage And Physical Function Among Middle-Aged To Older Adults, Hui Yee Loh Jun 2018

The Contribution Of The Neighbourhood Environment To The Relationship Between Neighbourhood Disadvantage And Physical Function Among Middle-Aged To Older Adults, Hui Yee Loh

Theses

Background

With the continuing increases in life expectancies in developed countries, an important public health goal is to ensure successful ageing—morbidity compression, maintenance of physical functioning and active engagement in life. It is well established that the onset of physical function decline begins in mid-life, and functional capacity is critical to maintaining mobility, independence and quality of life. A growing body of literature has found that residents of more disadvantaged neighbourhoods have significantly poorer physical function, independent of individual-level factors. However, the mechanisms through which neighbourhood environments are associated with this relationship remain largely unknown.

The overarching aim of ...

Access to public open space is important to increase leisure-time walking (LTW) in high-income countries, but there is little evidence in middle-income countries. We conducted a cross-sectional analysis to examine the relationship between LTW and the presence of different public open spaces (parks, bike paths, and squares) and the mix of these recreational destinations near the homes of adults participating in the Sao Paulo Health Survey (n = 3145). LTW was evaluated by a questionnaire. We delineated buffers (500, 1000, and 1500 m) from the geographic coordinates of the adults’ residential addresses using a geographic information system. We used multilevel logistic ...

Walkability And Walking For Transport: Characterizing The Built Environment Using Space Syntax, Mohammad Javad Koohsari, Neville Owen, Ester Cerin, Billie Giles-Corti, Takemi Sugiyama

Faculty of Health Sciences Publications

Background: Neighborhood walkability has been shown to be associated with walking behavior. However, the availability of geographical data necessary to construct it remains a limitation. Building on the concept of space syntax, we propose an alternative walkability index, space syntax walkability (SSW). This study examined associations of the full walkability index and SSW with walking for transport (WT). Methods: Data were collected in 2003–2004 from 2544 adults living in 154 Census Collection Districts (CCD) in Adelaide, Australia. Participants reported past week WT frequency. Full walkability (consisting of net residential density, intersection density, land use mix, and net retail area ...

To reverse the global epidemic of physical inactivity that is responsible for more than 5 million deaths per year, many groups recommend creating “activity-friendly environments.” Such environments may have other benefits, beyond facilitating physical activity, but these potential co-benefits have not been well described. The purpose of the present paper is to explore a wide range of literature and conduct an initial summary of evidence on co-benefits of activity-friendly environments. An extensive but non-systematic review of scientific and “gray” literature was conducted. Five physical activity settings were defined: parks/open space/trails, urban design, transportation, schools, and workplaces/buildings. Several ...

This study examined the strength and shape of associations between perceived environmental attributes and adults’ recreational walking, using data collected from 13,745 adult participants in 12 countries. Perceived residential density, land use mix, street connectivity, aesthetics, safety from crime, and proximity to parks were linearly associated with recreational walking, while curvilinear associations were found for residential density, land use mix, and aesthetics. The observed associations were consistent across countries, except for aesthetics. Using data collected from environmentally diverse countries, this study confirmed findings from prior single-country studies. Present findings suggest that similar environmental attributes are associated with recreational walking ...


People Living In Hilly Residential Areas In Metropolitan Perth Have Less Diabetes: Spurious Association Or Important Environmental Determinant?, Karen Villanueva, Matthew Knuiman, Mohammad Javad Koohsari, Sharyn Hickey, Sarah Foster, Hannah Badland, Andrea Grace Nathan, Fiona Bull, Billie Giles-Corti Jan 2013

People Living In Hilly Residential Areas In Metropolitan Perth Have Less Diabetes: Spurious Association Or Important Environmental Determinant?, Karen Villanueva, Matthew Knuiman, Mohammad Javad Koohsari, Sharyn Hickey, Sarah Foster, Hannah Badland, Andrea Grace Nathan, Fiona Bull, Billie Giles-Corti

Faculty of Health Sciences Publications

Background: 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’ neighbourhoods was associated with diabetes prevalence among the Australian adult population.

Faculty of Health Sciences Publications

Background: Increasing empirical evidence supports associations between neighborhood environments and physical activity. However, since most studies were conducted in a single country, particularly western countries, the generalizability of associations in an international setting is not well understood. The current study examined whether associations between perceived attributes of neighborhood environments and physical activity differed by country. Methods: Population representative samples from 11 countries on five continents were surveyed using comparable methodologies and measurement instruments. Neighborhood environment × country interactions were tested in logistic regression models with meeting physical activity recommendations as the outcome, adjusted for demographic characteristics. Country-specific associations were reported. Results ...

Children's Physical Activity And Parents' Perception Of The Neighborhood Environment: Neighborhood Impact On Kids Study, Karyn A. Tappe, Karen Glanz, James F. Sallis, Chuan Zhou, Brian E. Saelens

Faculty of Health Sciences Publications

Background: Physical activity is important to children’s physical health and well-being. Many factors contribute to children’s physical activity, and the built environment has garnered considerable interest recently, as many young children spend much of their time in and around their immediate neighborhood. Few studies have identified correlates of children’s activity in specific locations. This study examined associations between parent report of their home neighborhood environment and children’s overall and location-specific physical activity. Methods: Parents and children ages 6 to 11 (n=724), living in neighborhoods identified through objective built environment factors as high or low in ...

Faculty of Health Sciences Publications

Background: High rates of physical inactivity compromise the health status of populations globally. Social networks have been shown to influence physical activity (PA), but little is known about how best to engineer social networks to sustain PA. To improve procedures for building networks that shape PA as a normative behavior, there is a need for more specific hypotheses about how social variables influence PA. There is also a need to integrate concepts from network science with ecological concepts that often guide the design of in-person and electronically-mediated interventions. Therefore, this paper: (1) proposes a conceptual model that integrates principles from ...

Access To Commercial Destinations Within The Neighbourhood And Walking Among Australian Older Adults, Andrea Grace Nathan, Gavin Pereira, Sarah Foster, Paula Hooper, Dick Saarloos, Billie Giles-Corti

Faculty of Health Sciences Publications

Background Physical activity, particularly walking, is greatly beneficial to health; yet a sizeable proportion of older adults are insufficiently active. The importance of built environment attributes for walking is known, but few studies of older adults have examined neighbourhood destinations and none have investigated access to specific, objectively-measured commercial destinations and walking. Methods We undertook a secondary analysis of data from the Western Australian state government’s health surveillance survey for those aged 65–84 years and living in the Perth metropolitan region from 2003–2009 (n = 2,918). Individual-level road network service areas were generated at 400 m and ...

Using Gps Technology To (Re)-Examine Operational Definitions Of 'Neighbourhood' In Place-Based Health Research, Bryan Boruff, Andrea Grace Nathan, Sandra Nijënstein

Faculty of Health Sciences Publications

Background Inconsistencies in research findings on the impact of the built environment on walking across the life course may be methodologically driven. Commonly used methods to define ‘neighbourhood’, from which built environment variables are measured, may not accurately represent the spatial extent to which the behaviour in question occurs. This paper aims to provide new methods for spatially defining ‘neighbourhood’ based on how people use their surrounding environment. Results Informed by Global Positioning Systems (GPS) tracking data, several alternative neighbourhood delineation techniques were examined (i.e., variable width, convex hull and standard deviation buffers). Compared with traditionally used buffers (i ...
