Comparing childrenâs GPS tracks with non-objective geospatial measures of exposure to junk food
Various geospatial techniques have been employed to estimate childrenâs exposure to environmental cardiometabolic risk factors, including junk food. But many studies uncritically rely on exposure proxies which differ greatly from actual exposure. Misrepresentation of exposure by researchers could lead to poor decisions and ineffective policymaking. This study conducts a GIS-based analysis of GPS tracksââactivity spacesââand 21 proxies for activity spaces (e.g. buffers, container approaches) for a sample of 526 children (ages 9â14) in London, Ontario, Canada. These measures are combined with a validated food environment database (including fast food and convenience stores) to create a series of junk food exposure estimates and quantify the errors resulting from use of different proxy methods. Results indicate that exposure proxies consistently underestimate exposure to junk foods by as much as 68%. This underestimation is important to policy development because children are exposed to more junk food than estimated using typical methods
An application of the edge effect in measuring accessibility to multiple food retailer types in Southwestern Ontario, Canada
<p>Abstract</p> <p>Background</p> <p>Trends in food retailing associated with the consolidation of smaller-format retailers into fewer, larger-format supercentres have left some rural areas with fewer sources of nutritious, affordable food. Access to nutritious, affordable food is essential for good dietary habits and combating health issues such as type-2 diabetes, obesity, and cardiovascular disease. Many studies on food environments use inaccurate or incomplete methods for locating food retailers, which may be responsible for mischaracterising food deserts. This study uses databases of every residence in and every food retailer in and around Middlesex County, Ontario, Canada. Residences were geocoded to their precise address, and network analysis techniques were performed in a geographic information system (GIS) to determine distances between every residence and different types of food retailers (grocery stores, fast food, fruit and vegetable sources, grocery stores plus fruit and vegetable sources, variety stores), both when considering and neglecting facilities outside the area of study, to account for a deficiency in analysis termed the 'edge effect'.</p> <p>Results</p> <p>Analysis of household accessibility to food outlets by neighbourhood socioeconomic distress level indicated that residents in the most distressed neighbourhoods tended to have better accessibility to all types of food retailers. In the most distressed neighbourhoods, 79 percent of residences were within walking distance of a grocery store, compared to only 10 percent in the least distressed neighbourhoods. When the edge effect was neglected, 37 percent of distance estimates proved inaccurate. Average accessibility to all food retailer types improved dramatically when food outlets adjacent to the study area were considered, thereby controlling for the edge effect.</p> <p>Conclusion</p> <p>By neglecting to consider food retailers just outside study area boundaries, previous studies may significantly over-report the actual distance necessary to travel for food. Research on food access spanning large rural regions requires methods that accurately geocode residents and their food sources. By implementing methods akin to those in this paper, future research will be better able to identify areas with poor food accessibility. Improving identification of food desert communities is a first step in facilitating more effective deployment of food policies and programs in those communities.</p
A food retail-based intervention on food security and consumption
The effect of the built environment on diet (and ensuing health outcomes) is less understood than the effect of diet on obesity. Natural experiments are increasingly advocated in place of cross-sectional studies unable to suggest causality. The central research question of this paper, therefore, asks whether a neighborhood-level food retail intervention will affect dietary habits or food security. The intervention did not have a significant impact on fruit and vegetable consumption, and the intervention population actually purchased prepared meals more frequently. More problematic, only 8% of respondents overall regularly consumed enough fruits and vegetables, and 34% were food insecure. Further complicating this public health issue, the new grocery store closed after 17 months of operation. Results indicate that geographic access to food is only one element of malnutrition, and that multi-pronged dietary interventions may be more effective. The economic failure of the store also suggests the importance of non-retail interventions to combat malnutrition
An economic impact comparative analysis of farmersâ markets in Michigan and Ontario
Farmers\u27 markets play a vital role in local economic development by providing a site for local and small business incubation, creating an economic multiplier effect to neighboring businesses, and recycling customer dollars within the community. While several studies have evaluated characteristics of farmers\u27 markets within single metropolitan areas, few have compared the impact of multiple markets in socioeconomically contrasting regions.
This research compares shopping habits and economic impacts of customers at farmers\u27 markets in two North American cities: Flint, Michigan, and London, Ontario. Overall, 895 market visitors completed surveys. We conducted statistical and spatial analyses to identify differences between these markets. Though geographically proximate and similar in metropolitan size, the two cities differ greatly in recent economic development, social vitality, and public health indicators. The objectives of this article are to quantify the impact that each market has on its local economy and contextualize these impacts in light of the place-specific attributes of each market.
Results indicate that customers come from a mix of urban and suburban locations, but that key urban areas do not draw a substantial share of customers. Marketing efforts in nearby disadvantaged neighborhoods, therefore, might yield new customers and increase multiplier effects within the neighborhoods. The London market drew slightly younger customers who shopped less frequently, while the Flint market drew an older crowd that attended more regularly. This may be attributable to the relative age of the markets, and certainly reflects the marketing push of each market\u27s managers. Given the opportunity to compare similarities and differences, much can be learned from each market in terms of opportunities for marketing, local economic development, and increased community vitality
Is it sound poilcy or fast policy? Practitionerâs perspectives on the role of place branding local economic development.
In response to neoliberal policies and globalization pressures over the past three decades, urban governments in advanced economies have, with near-unanimity, adopted place branding as an approach to foster local economic growth. Framed as an outcome of multilevel neoliberal policymaking and local entrepreneurial governance, place branding has been adopted by urban places at all scales and geographic contexts with little regard for its efficacy. It is unclear, however, whether place branding represents a substantive approach, or is merely an emerging example of a neoliberal scripting. In many regards, the debate surrounding place branding is similar to the discourse on the Creative Class a decade ago. Consequently, uncertainty exists regarding whether place branding reflects practical and responsible urban governance or a superficial, fast policy with limited potential to foster local development. To date, little is known about how practitioners perceive place branding as a policy tool in the context of economic development. This study examines the perceptions of economic development practitioners regarding how place branding is being developed and implemented as a policy tool. The analysis is based on in-depth interviews with economic development practitioners (n = 25) from a wide range of municipalities in Ontario. Findings of this study indicate that while opportunity exists for place branding to represent in-depth and extensive local development policy, it is more generally an urban development script for creating a sense of place and fostering local economic development. Additionally, the majority of place branding policy represents superficial policy, emphasizing hegemonic approaches. Place branding can therefore be explained as an example of fast policy
The role of place branding in local and regional economic development: bridging the gap between policy and practicality
Place branding has become an increasingly integral part of local and regional economic development strategies in the global competition for business investment. Professional and academic understanding remains limited, however, regarding whether place branding can be classified as a âhigh-roadâ policy with substantive and effective merits or a âlow-roadâ policy that is generally inefficient and ineffective at fostering sustainable economic growth. Through the context of business attraction, this study examines whether place branding represents âhigh-roadâ policy by comparing what economic development practitioners are doing to create and support their brands against the needs and desires of businesses considering relocation. The research goal is achieved through a series of in-depth interviews with economic development practitioners (n = 25) and private-sector site selectors (n = 10) in the province of Ontario, Canada. Gaps between policy and practicality are identified by comparing the responses of the two groups. Results demonstrate that place branding has the potential to be âhigh-roadâ policy given its utility in business attraction. In its current implementation, however, place branding remains better described as a âlow-roadâ policy, as it is not being used efficiently. Several gaps in place-branding policy are identified, including an overreliance on visual identities and narratives, poor communication of the brand information, and overemphasis on presenting quality of life and affordability. These gaps present possible areas of ineffectiveness that can limit the ability of a place brand to attract investment, but provide areas of future policy improvements, thus enabling place branding to shift from âlow roadâ to âhigh roadâ
A comparative analysis of the restaurant consumer food environment in Rochester (NY, USA) and London (ON, Canada): assessing childrenâs menus by neighbourhood socio-economic characteristics
Objective:To assess restaurant childrenâs menus for content and nutritional quality; and to investigate the relationship between the restaurant consumer food environment for children and neighbourhood-level socio-economic characteristics within and between one Canadian city and one US city. Design: Cross-sectional observational study. Setting: London, ON, Canada and Rochester, NY, USA. Participants: Restaurant childrenâs menus were assessed, scored and compared using the Childrenâs Menu Assessment tool. We quantified neighbourhood accessibility to restaurants by calculating 800 m road-network buffers around the centroid of each city census block and created a new Neighbourhood Restaurant Quality Index for Children (NRQI-C) comprising the sum of restaurant menu scores divided by the total number of restaurants within each area. After weighting by population, we examined associations between NRQI-C and neighbourhood socio-economic characteristics using correlations and multiple regression analyses. Results: Nutritional quality of childrenâs menus was greater, on average, in Rochester compared with London. Only one variable remained significant in the regression analyses for both cities: proportion of visible minorities had a positive effect on neighbourhood NRQI-C scores in London, whereas the reverse was true in Rochester. Conclusions: Results suggest the presence of a socio-economic disparity within Rochester, where children in more disadvantaged areas have poorer access to better nutritional quality restaurant choices. In London, results suggest an inverse relationship across the city where children in more disadvantaged areas have better access to better nutritional quality restaurant choices. Given these disparate results, research on restaurant nutritional quality for children requires additional consideration
Inequitable Housing Practices and Youth Internalizing Symptoms: Mediation Via Perceptions of Neighborhood Cohesion
Disordered urban environments negatively impact mental health symptoms and disorders. While many aspects of the built environment have been studied, one influence may come from inequitable, discriminatory housing practices such as redlining, blockbusting, and gentrification. The patterns of disinvestment and reinvestment that follow may be an underlying mechanism predicting poor mental health. In this study, we examine pathways between such practices and internalizing symptoms (i.e., anxiety and depression) among a sample of African American youth in Baltimore, Maryland, considering moderation and mediation pathways including neighborhood social cohesion and sex. In our direct models, the inequitable housing practices were not significant predictors of social cohesion. In our sex moderation model, however, we find negative influences on social cohesion: for girls from gentrification, and for boys from blockbusting. Our moderated mediation model shows that girls in gentrifying neighborhoods who experience lower social cohesion have higher levels of internalizing symptoms. Likewise for boys, living in a formerly blockbusted neighborhood generates poorer social cohesion, which in turn drives higher rates of internalizing symptoms. A key implication of this work is that, in addition to standard measures of the contemporary built environment, considering other invisible patterns related to discriminatory and inequitable housing practices is important in understanding the types of neighborhoods where anxiety and depression are more prevalent. And while some recent work has discussed the importance of considering phenomena like redlining in considering long-term trajectories of neighborhoods, other patterns such as blockbusting and gentrification may be equally important
