New charter schools can potentially provide disenfranchised students with enhanced academic opportunities while simultaneously serving as neighborhood anchors that reinforce neighborhood socioeconomic growth. However, for both of these arguments to be true, charter schools would have to replace low‐performing public schools in currently disadvantaged, but revitalizing, neighborhoods. Using data from the Chicago Public Schools, the Common Core, and the Census, we examine the neighborhood and school‐level factors that account for where elementary schools closed and opened in Chicago during the late 1990s and 2000s. We find that schools in disadvantaged neighborhoods were more likely to close, but only because these were also underperforming and under‐enrolled schools. After controlling for educational demand, new schools were more likely to open in neighborhoods that showed signs of socioeconomic revitalization and declining proportions of white residents.
Environmental and socioeconomic factors affect bladder cancer mortality and effects appear to vary by gender and race. Additionally there were temporal trends of bladder cancer hot spots which, when persistent, should be the focus of individual level studies of occupational and environmental factors.
Background
For patients receiving hemodialysis, distance to their dialysis facility may be particularly important due to the need for thrice weekly dialysis. We sought to determine whether African-Americans and Whites differ in proximity and access to high quality dialysis facilities.
Methods
We analyzed urban, Whites and African-Americans aged 18-65 receiving in-center hemodialysis linked to data on neighborhood and dialysis facility quality measures. In multivariable analyses, we examined the association between individual and neighborhood characteristics, and our outcomes: distance from home zip code to nearest dialysis facility, their current facility and the nearest high quality facility, as well as likelihood of receiving dialysis in a high quality facility.
Results
African-Americans lived a half mile closer to a dialysis facility (B=-0.52) but traveled the same distance to their own dialysis facility compared to Whites. In initial analysis, African-Americans are 14% less likely than their White counterparts to attend a high quality dialysis facility (OR 0.86); and those disparities persist, though are reduced, even after adjusting for region, neighborhood poverty and percent African-American. In predominately African-American neighborhoods, individuals lived closer to high quality facilities (B=--5.92), but were 53% less likely to receive dialysis there (OR 0.47, highest group versus lowest, p<0.05). Living in a predominately African-American neighborhood explains 24% of racial disparity in attending a high quality facility.
Conclusions
African-Americans' proximity to high quality facilities does not lead to receiving care there. Institutional and social barriers may also play an important role in where people receive dialysis.
Spatial analysis using GIS identified associations between pediatric pedestrian motor vehicle crash sites and the neighborhoods served by our pediatric trauma center. Pediatric pedestrian motor vehicle crash sites occurred predominantly within low-income, African-American neighborhoods. The disparity in prevalence of crash sites is somewhat attributable to the lower density of children living in the predominantly higher income, non-African-American neighborhoods, including the community immediately around our hospital. Traffic volume patterns, as a denominator of these injury events, remain to be studied.
Using geospatial analysis, we examined the relationship of distance between a patient's residence and clinic, travel time to clinic, and neighborhood violent crime rates with retention in care or viral suppression among people living with HIV (PLWH). For HIV-positive patients at a large urban clinic, we measured distance and travel time between home and clinic and violent crime rate within a two block radius of the travel route. Kruskal-Wallis rank sum was used to compare outcomes between groups. Over the observation period, 2008-2016, 219/602 (36%) patients were retained in care. Median distance from clinic was 3.6 (IQR 2.1-5.6) miles versus 3.9 (IQR 2.7-6.1) miles among those retained versus not retained in care, p = 0.06. Median travel time by car was 15.9 (IQR 9.6-22.9) versus 17.1 (IQR 12.0-24.6) minutes for those retained versus not retained, p = 0.04. Violent crime rate along travel route was not associated with retention. There was no significant association between travel time or distance and viral suppression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
