Spatial inequalities in urban infrastructure for physical activity in Greater Santiago, Chile
This study characterized urban infrastructure (UI) supporting physical activity (PA) in Greater Santiago (GS), Chile, and examined its spatial distribution. A conceptual model comprising four key dimensions — active transport, green areas, public transport, and safety — was used to guide selection of relevant indicators (23 total). Statistical and spatial analyses were conducted across 34 municipalities and 1623 neighborhoods using a summary inde…
Aarp Age-Friendly community designation and neighborhood resources to support healthy aging nationwide, 2012–2017
These findings suggest a meaningful association between local Age-Friendly designation and the availability of resources that can support aging in place. Although we did not directly measure health outcomes, neighborhoods with greater resource density are likely to experience multiple health benefits, including improved quality of life for older adults
Twenty-five-year changes in alcohol environment in US metropolitan areas
National trends and disparities in retail food environments in the USA between 1990 and 2014
Objective: To describe national disparities in retail food environments by neighbourhood composition (race/ethnicity and socio-economic status) across time and space. Design: We examined built food environments (retail outlets) between 1990 and 2014 for census tracts in the contiguous USA ( n 71 547). We measured retail food environment as counts of all food stores, all unhealthy food sources (including fast food, convenience stores, bakeries and…
Does Living near Trees and Other Vegetation Affect the Contemporaneous Odds of Asthma Exacerbation among Pediatric Asthma Patients
Inequities in spatial accessibility to Covid-19 testing in 30 large US cities
Testing for SARS-CoV-2 infection has been a key strategy to mitigate and control the COVID-19 pandemic. Wide spatial and racial/ethnic disparities in COVID-19 outcomes have emerged in US cities. Previous research has highlighted the role of unequal access to testing as a potential driver of these disparities. We described inequities in spatial accessibility to COVID-19 testing locations in 30 large US cities. We used location data from Castlight …
Associations between Greenspace and Gentrification-Related Sociodemographic and Housing Cost Changes in Major Metropolitan Areas across the United States
Neighborhood greenspace may attract new residents and lead to sociodemographic or housing cost changes. We estimated relationships between greenspace and gentrification-related changes in the 43 largest metropolitan statistical areas (MSAs) of the United States (US). We used the US National Land Cover and Brown University Longitudinal Tracts databases, as well as spatial lag models, to estimate census tract-level associations between percentage g…

Burden of Uncontrolled Hyperglycemia and Its Association with Patients Characteristics and Socioeconomic Status in Philadelphia, USA
Purpose: To examine the burden of uncontrolled hyperglycemia in patients with diabetes mellitus (DM) and their characteristics in a large urban city. Methods: A randomized sample of 4993 patients with DM ≥18 years old who received routine health care in a large university teaching hospital in the city of Philadelphia was analyzed. Uncontrolled hyperglycemia was classified as blood hemoglobin A1c >8%. The associations of uncontrolled hyperglycemia…
Neighborhood Violent Crime and Perceived Stress in Pregnancy
Stress has been shown to adversely affect pregnancy outcomes. Neighborhood crime rates may serve as one publicly available social determinant of health for pregnancy studies that use registry or electronic health record datasets in which individual-level stress data are not available. We sought to determine whether neighborhood violent crime incidents were associated with measured perceived stress in a largely minority, urban pregnancy cohort. We…
High Ambient Temperature and Infant Mortality in Philadelphia, Pennsylvania
Objective. To quantify the association between heat and infant mortality and identify factors that influence infant vulnerability to heat. Methods. We conducted a time-stratified case–crossover analysis of associations between ambient temperature and infant mortality in Philadelphia, Pennsylvania, during the warm months of 2000 through 2015. We used conditional logistic regression models to estimate associations of infant mortality with daily tem…
Spatial accessibility to pediatric primary care in Philadelphia
A new measure of pediatric primary care accessibility demonstrates a persistent disparity in primary care access for predominantly non-Hispanic Black neighborhoods
Effects of Proximity to Supermarkets on a Randomized Trial Studying Interventions for Obesity
Objectives. To determine whether proximity to a supermarket modified the effects of an obesity intervention. Methods. We examined 498 children aged 6 to 12 years with a body mass index (BMI) at or above the 95th percentile participating in an obesity trial in Massachusetts in 2011 to 2013. The practice-based interventions included computerized clinician decision support plus family self-guided behavior change or health coaching. Outcomes were 1-y…
Intraurban and Longitudinal Variability of Classical Pollutants in Kraków, Poland, 2000–2010
In spite of a dramatic decrease in anthropogenic emissions, ambient concentrations of major pollutants have not changed within many urban locations. To clarify the relationship between ambient air quality trend and the population exposures, we compared the intraurban versus temporal variability of the collocated measurements of five major air pollutants including particulate matter (PM) with an aerodynamic diameter <10 μm (PM10), < 2.5 μm (PM2.5)…
The association of urbanicity with infant sleep duration
Program practices and demographic factors associated with federal funding for the Safe Routes to School program in the United States
In 2005, the United States Congress authorized $612 million for use in implementing the US Safe Routes to School program to address physical inactivity, air quality, safety and traffic near schools. Each US state developed administrative practices to implement the program. Based on state-specific annual obligations, on average, states have obligated 44% of available funds. State project obligations were directly associated with programmatic facto…
Validation of Walk Scores and Transit Scores for estimating neighborhood walkability and transit availability
Validation of Walk Score® for Estimating Neighborhood Walkability
Neighborhood walkability can influence physical activity. We evaluated the validity of Walk Score(®) for assessing neighborhood walkability based on GIS (objective) indicators of neighborhood walkability with addresses from four US metropolitan areas with several street network buffer distances (i.e., 400-, 800-, and 1,600-meters). Address data come from the YMCA-Harvard After School Food and Fitness Project, an obesity prevention intervention in…
The Built Environment and Location-Based Physical Activity
Austin Et Al. Respond
We thank Spielman for commenting on our article and giving us an opportunity to continue the dialogue on methodological issues in studying food environments. In response to his point about network versus straight-line distances, we would like to note that in a related study, our research team found network and straight-line distances in Chicago to be highly correlated, and results did not differ when models were tested with network versus straigh…
Clustering of Fast-Food Restaurants Around Schools
Objectives. We examined the concentration of fast food restaurants in areas proximal to schools to characterize school neighborhood food environments. Methods. We used geocoded databases of restaurant and school addresses to examine locational patterns of fast‐food restaurants and kindergartens and primary and secondary schools in Chicago. We used the bivariate K function statistical method to quantify the degree of clustering (spatial dependence…
