The utility of street view imagery in environmental audits for runnability
Placial-Discursive Topologies of Violence: Volunteered Geographic Information and the Reproduction of Violent Places in Recife, Brazil
Knowledge and experiences of violence transform the ways in which individuals perceive the urban landscape, construct and reproduce (un)safety, and make everyday decisions regarding mobility and the use of space. This knowledge and these experiences are placially anchored and are shaped by everyday regionalisations. In the context of interpersonal violence in Recife, Brazil, we examine the ways in which volunteered geographic information (VGI), f…
Experiences of place-bound sociality amidst the Covid-19 pandemic: A qualitative analysis of environment-related coping strategies
In the context of the COVID-19 pandemic, places of public encounter were effectively inhibited by lockdown regulations. In addition to several quantitative studies of the impact of the ongoing pandemic on society, little is known about the use of one’s spatial environment on individual coping strategies mitigating physical isolation. Through an explorative qualitative study we derived a typology of coping strategies that helped participants to ba…
Neighborhood Greenspace and Socioeconomic Risk are Associated with Diabetes Risk at the Sub-neighborhood Scale: Results from the Prospective Urban and Rural Epidemiology (Pure) Study
Greenspace and socioeconomic status are known correlates of diabetes prevalence, but their combined effects at the sub-neighborhood scale are not yet known. This study derives, maps, and validates a combined socioeconomic/greenspace index of individual-level diabetes risk at the sub-neighborhood scale, without the need for clinical measurements. In two Canadian cities (Vancouver and Hamilton), we computed 4 greenspace variables from satellite ima…
Spatial-temporal patterns of homicide in socioeconomically deprived settings: Violence in Alagoas, Brazil, 2006‒2015
BACKGROUND: Homicide presents a significant health burden globally, but geographical differences in homicide rates necessitate focussed analyses of spatial and temporal patterns, particularly in affected areas. The highest rates are concentrated in regions in Central and South America, but analyses of sub-regional patterns and sex-specific differences may yield important information for addressing the upstream causes of homicide at the community …
Towards a Situated Spatial Epidemiology of Violence: A Placially-Informed Geospatial Analysis of Homicide in Alagoas, Brazil
This paper presents an empirically grounded call for a more nuanced engagement and situatedness with placial characteristics within a spatial epidemiology frame. By using qualitative data collected through interviews and observation to parameterise standard and spatial regression models, and through a critical interpretation of their results, we present initial inroads for a situated spatial epidemiology and an analytical framework for health/med…
Qualitative Field Observation of Pedestrian Injury Hotspots: A Mixed-Methods Approach for Developing Built- and Socioeconomic-Environmental Risk Signatures
Road traffic injuries constitute a significant global health burden; the World Health Organization estimates that they result in 1.35 million deaths annually. While most pedestrian injury studies rely predominantly on statistical modelling, this paper argues for a mixed-methods approach combining spatial analysis, environmental scans, and local knowledge for assessing environmental risk factors. Using data from the Nova Scotia Trauma Registry, se…
Simulating Urban Land Expansion in the Context of Land Use Planning in the Abuja City-Region, Nigeria
In the Global South, including the Sub-Saharan African city-regions, the possible future urban expansion patterns may pose a challenge towards improving environmental sustainability. Land use planning strategies and instruments for regulating urban expansion are faced with challenges, including insufficient data availability to offer insights into the possible future urban expansion. This study integrated empirical data derived from Geographic In…
Multimorbidity and Socioeconomic Deprivation among Older Adults: A Cross-sectional Analysis in Five Canadian Cities Using the CLSA
Individual socioeconomic status is known to correlate with multimorbidity, but the role of neighbourhood-level socioeconomic deprivation is uncertain. Participants from five cities (n = 16,313) from the Canadian Longitudinal Study on Aging were mapped by postal code and their local area socioeconomic deprivation scores were calculated using the Vancouver Area Neighbourhood Deprivation Index. Logistic regression models were used to estimate depriv…
Disparities in Paediatric Injury Mortality between Aboriginal and Non-Aboriginal Populations in British Columbia, 2001–2009
Injury is the leading cause of death among children and youth in Canada. Significant disparities in injury mortality rates have been observed between Aboriginal and non-Aboriginal populations, but little is known about the age-, sex-, and mechanism-specific patterns of injury causing death. This study examines paediatric mortality in British Columbia from 2001 to 2009 using comprehensive vital statistics registry data. We highlight important disp…
A description of methods for deriving air pollution land use regression model predictor variables from remote sensing data in Ulaanbaatar, Mongolia
Key Messages Air pollution is a leading risk factor for death and disease globally. Land use regression (LUR) modelling is a commonly used exposure assessment tool, but spatially resolved data are required to generate predictor variables in LUR models. LUR model predictors can be derived at little or no cost from satellite data and high‐resolution imagery

Intentional injury and violence in Cape Town, South Africa: An epidemiological analysis of trauma admissions data
BACKGROUND: Injury is a truly global health issue that has enormous societal and economic consequences in all countries. Interpersonal violence is now widely recognized as important global public health issues that can be addressed through evidence-based interventions. In South Africa, as in many low- and middle-income countries (LMIC), a lack of ongoing, systematic injury surveillance has limited the ability to characterize the burden of violenc…
Suburbanisation of oral cavity cancers: Evidence from a geographically-explicit observational study of incidence trends in British Columbia, Canada, 1981–2010
While the aging of suburban populations provides some explanation of these trends, we highlight the role of the suburbanisation of socioeconomically deprived and Asia-born populations, known to have higher rates of risk behaviours such as tobacco, alcohol, and betel/areca consumption. Specifically, betel/areca consumption among Asia-born populations is suspected to be a primary driver of the observed geographical shift in incidence from urban cor…
