What explains the concentration of off-premise alcohol outlets in Black neighborhoods?

Overview of State Laws Restricting Alcohol Outlet Density in the United States

OBJECTIVES

Complementing the extensive research literature demonstrating that increased alcohol outlet density is associated with excessive alcohol consumption and related harms, this article synthesizes information on the types of alcohol outlet density restrictions in US state-level laws.

DESIGN

Statutes and regulations related to alcohol outlet density in all 50 states and the District of Columbia in effect as of January 1, 2022, were collected using Westlaw. State-level density restrictions were coded according to 4 variables and overlaid with existing research on state-specific local authority to regulate outlet density. Alcohol outlet density laws in Michigan and Massachusetts were analyzed in detail as case studies.

SETTING

United States.

MAIN OUTCOME MEASURE

US state-level licensing laws restricting alcohol outlet density.

RESULTS

Thirty-three states and the District of Columbia have state-level licensing laws that limit alcohol outlet density. Of those, 25 have population-based restrictions, 8 have distance-based restrictions, 7 have quotas, and 6 require the licensing agency to consider density-related factors. Within the same group of 34 jurisdictions, 22 apply restrictions to both on- and off-premises outlets, 5 apply them only to on-premises outlets, and 7 apply them only to off-premises outlets. Among the 32 states where localities lack authority to license alcohol outlets, two-thirds have state-level laws restricting outlet density. State-level density restrictions also exist in approximately two-thirds of the states where localities have licensing authority. Case studies of Michigan and Massachusetts highlight how state-level density restrictions operate in practice.

CONCLUSIONS

Two-thirds of jurisdictions have state-level alcohol outlet density restrictions, with population-based restrictions being the most common. In addition, outlet density restrictions may exist regardless of limits on local control and whether localities with authority to enact density restrictions have done so. Policymakers and others can reference this assessment to identify examples and opportunities to strengthen the alcohol policy environment in any given state.

Evaluating Methods for Mapping Historical Redlining to Census Tracts for Health Equity Research

Neighborhood characteristics including housing status can profoundly influence health. Recently, increasing attention has been paid to present-day impacts of "redlining," or historic area classifications that indicated less desirable (redlined) areas subject to decreased investment. Scholarship of redlining and health is emerging; limited guidance exists regarding optimal approaches to measuring historic redlining in studies of present-day health outcomes. We evaluated how different redlining approaches (map alignment methods) influence associations between redlining and health outcomes. We first identified 11 existing redlining map alignment methods and their 37 logical extensions, then merged these 48 map alignment methods with census tract life expectancy data to construct 9696 linear models of each method and life expectancy for all 202 redlined cities. We evaluated each model's statistical significance and R2 values and compared changes between historical and contemporary geographies and populations using Root Mean Squared Error (RMSE). RMSE peaked with a normal distribution at 0.175, indicating persistent difference between historical and contemporary geographies and populations. Continuous methods with low thresholds provided higher neighborhood coverage. Weighting methods had more significant associations, while high threshold methods had higher R2 values. In light of these findings, we recommend continuous methods that consider contemporary population distributions and mapping overlap for studies of redlining and health. We developed an R application {holcmapr} to enable map alignment method comparison and easier method selection.

Delta-8 THC Retail Availability, Price, and Minimum Purchase Age

Background: Retail sales of Delta-8 tetrahydrocannabinol (THC) products have increased in the U.S. market since the passing of the 2018 Farm Bill, and there is currently little regulation of marketing/sales and limited related safety standards in many states. After thousands of calls to poison control centers (40% for individuals under 18 years old and 70% requiring health care facility evaluation), the Food and Drug Administration issued warnings on Delta-8 THC products, stating their psychoactive effects and that some manufacturers may synthesize Delta-8 using unsafe household chemicals. The current study describes the Delta-8 THC retail sales environment in Fort Worth, Texas. Given its relatively inexpensive manufacturing and that low prices are a major determinant of cannabis use, the price of Delta-8 THC products was examined. This study also examined whether retail outlets in areas with greater socioeconomic deprivation had higher odds of selling Delta-8 THC products. This is important because if Delta-8 THC retailers are disproportionately located in more socioeconomically deprived communities, residents of these communities can more easily access these products and may have higher risk of adverse consequences. Methods: Potential Delta-8 THC retailers were selected by identifying lists of current retail locations with alcohol, cannabidiol, and/or tobacco licenses in Fort Worth. Trained research assistants called outlets in September and October 2021 to query about sales of products containing Delta-8 THC. The response rate was 69% (n=1,223). Outlets' 9-digit zip codes were merged with Area Deprivation Index scores. Products and purported minimum age were described. Chi-squared and Student's t-tests were used. Results: Eleven percent of outlets (n=133) reported selling Delta-8 THC. Ninety-six percent sold vapes and/or "flower" (i.e., hemp leaves coated with Delta-8 THC distillate) and 76% sold edibles. Among the least expensive products available, edibles cost, on average, $8.58 less than flower/vapes (p<0.001). Outlets that sold Delta-8 THC were located in areas with greater deprivation (p=0.02). Most reported a minimum purchase age of 21; however, 4% reported 18 years or no minimum age. Conclusions: Delta-8 THC retail outlets were disproportionately located in areas with more socioeconomic deprivation. Legal intervention such as zoning, minimum age, and tax laws may help reduce Delta-8 THC-related disparities.

Tobacco and Alcohol Retailer Availability and Neighborhood Racialized, Economic, and Racialized Economic Segregation in North Carolina

BACKGROUND

Despite evidence of racialized and socioeconomic inequities in tobacco and alcohol outlet availability, few studies have investigated spatial inequities in areas experiencing both concentrated residential racialized segregation and socioeconomic disadvantage. This study examined whether segregation-racialized, economic or both-was associated with alcohol and tobacco retailer counts in North Carolina (NC).

METHODS

The NC Alcoholic Beverage Control Commission provided lists of 2021 off-premise alcohol retailers. We created a list of 2018 probable tobacco retailers using ReferenceUSA. We calculated three census tract-level measures of the Index of Concentrations at the Extremes (ICE), indicating racialized segregation between non-Hispanic White and Black residents and economic segregation based on household income. We used negative binomial regression to test associations between quintiles of each ICE measure and tobacco and, separately, alcohol retailer counts.

RESULTS

Tracts with the greatest racialized disadvantage had 38% (IRR, 1.38; 95% CI, 1.15-1.66) and 65% (IRR, 1.65; 95% CI, 1.34-2.04) more tobacco and alcohol outlets, respectively, as tracts with the lowest. Tracts with the highest racialized economic disadvantage had a predicted count of 1.51 tobacco outlets per 1000 people while those in the lowest had nearly one fewer predicted outlet. Similar inequities existed in the predicted count of alcohol outlets.

DISCUSSION

Tobacco and alcohol outlet availability are higher in NC places experiencing concentrated racialized and economic segregation. A centralized agency overseeing tobacco and alcohol outlet permits and strategies to reduce the retail availability of these harmful products (e.g., capping the number of permits) are needed to intervene upon these inequities.

Racial and Ethnic Representation in Preventive Intervention Research: a Methodological Study

Individuals who are Asian or Asian American, Black or African American, Native American or American Indian or Alaska Native, Native Hawaiian or Pacific Islander, and Hispanic or Latino (i.e., presently considered racial ethnic minoritized groups in the USA) lacked equal access to resources for mitigating risk during COVID-19, which highlighted public health disparities and exacerbated inequities rooted in structural racism that have contributed to many injustices, such as failing public school systems and unsafe neighborhoods. Minoritized groups are also vulnerable to climate change wherein the most severe harms disproportionately fall upon underserved communities. While systemic changes are needed to address these pervasive syndemic conditions, immediate efforts involve examining strategies to promote equitable health and well-being-which served as the impetus for this study. We conducted a descriptive analysis on the prevalence of culturally tailored interventions and reporting of sample characteristics among 885 programs with evaluations published from 2010 to 2021 and recorded in the Blueprints for Healthy Youth Development registry. Inferential analyses also examined (1) reporting time trends and (2) the relationship between study quality (i.e., strong methods, beneficial effects) and culturally tailored programs and racial ethnic enrollment. Two percent of programs were developed for Black or African American youth, and 4% targeted Hispanic or Latino populations. For the 77% of studies that reported race, most enrollees were White (35%) followed by Black or African American (28%), and 31% collapsed across race or categorized race with ethnicity. In the 64% of studies that reported ethnicity, 32% of enrollees were Hispanic or Latino. Reporting has not improved, and there was no relationship between high-quality studies and programs developed for racial ethnic youth, or samples with high proportions of racial ethnic enrollees. Research gaps on racial ethnic groups call for clear reporting and better representation to reduce disparities and improve the utility of interventions.

Alcohol Misuse, Binge Drinking, and their Associations with Psychosocial Factors during COVID-19 among Harlem Residents in New York City

This study examined alcohol misuse and binge drinking prevalence among Harlem residents, in New York City, and their associations with psycho-social factors such as substance use, depression symptom severity, and perception of community policing during COVID-19. An online cross-sectional study was conducted among 398 adult residents between April and September 2021. Participants with a score of at least 3 for females or at least 4 for males out of 12 on the Alcohol Use Disorders Identification Test were considered to have alcohol misuse. Binge drinking was defined as self-reporting having six or more drinks on one occasion. Modified Poisson regression models were used to examine associations. Results showed that 42.7% used alcohol before COVID-19, 69.1% used it during COVID-19, with 39% initiating or increasing alcohol use during COVID-19. Alcohol misuse and binge drinking prevalence during COVID-19 were 52.3% and 57.0%, respectively. Higher severity of depression symptomatology, history of drug use and smoking cigarettes, and experiencing housing insecurity were positively associated with both alcohol misuse and binge drinking. Lower satisfaction with community policing was only associated with alcohol misuse, while no significant associations were found between employment insecurity and food insecurity with alcohol misuse or binge drinking. The findings suggest that Harlem residents may have resorted to alcohol use as a coping mechanism to deal with the impacts of depression and social stressors during COVID-19. To mitigate alcohol misuse, improving access to mental health and substance use disorder services, and addressing public safety through improving relations with police could be beneficial.

Micro-temporal analyses of crime related to alcohol outlets: A comparison of outcomes over weekday, weekend, daytime and nighttime hours

INTRODUCTION

Causal relationships between alcohol outlets and crime are inferred from their statistical associations across neighbourhoods. However, many unobserved covariates may confound these effects. Recognising that outlet sales vary by time of day and day of week, we assess whether areas with more bars/pubs, restaurants or off-premise outlets have more crime during days and times when alcohol sales are greatest.

METHODS

Annual administrative crime counts, sociodemographic data and other area characteristics of 336 Census block groups in Oakland, California, USA, were related to outlet densities from 2000 to 2015. Bayesian space-time Poisson models were used to measure associations between outlet densities and crime during: (i) weekday daytime; (ii) weekday nighttime; (iii) weekend daytime; and (iv) weekend nighttime periods (four seemingly unrelated equations). Comparisons of parameter estimates across equations provided an assessment of outlet effects on crime across days and times within the same analysis units using the same constellation of confounding covariates.

RESULTS

Assault and driving under the influence crime incidents during weekend evening hours were more frequent in Census block group areas with greater numbers of bar/pubs. Burglaries were consistently greater in areas with greater densities of restaurants.

DISCUSSION AND CONCLUSIONS

The spatiotemporal signature relating densities of bars/pubs over weekend evening hours to assault and driving under the influence incidents suggests that these outlets are a critical source of these crimes across neighbourhoods. Prevention programs and policies that focus upon specific drinking establishments, days and times may be most effective in reducing assault and impaired driving incidents in neighbourhoods.

Understanding the association between neighbourhood socioeconomic status and grocery store alcohol sales following market liberalization in Ontario, Canada

OBJECTIVES

In 2015, Ontario partially deregulated alcohol sales by allowing grocery stores to sell alcohol. The purpose of this study was to evaluate (1) whether neighbourhood-level socioeconomic status (SES) impacted the likelihood that a grocery store began selling alcohol, and (2) whether increases in alcohol retail availability following deregulation differed between neighbourhoods based on SES.

METHODS

This was a repeated cross-sectional analysis of 1062 grocery stores in 17,096 neighbourhoods in urban Ontario. The association between neighbourhood-level SES and whether a grocery store began selling alcohol was modeled using mixed effect logistic regression. The annual change in drive-distance from a neighbourhood to the closest off-premise alcohol outlet between 2015 and 2020 was modeled using mixed effect linear regression. An interaction between time and SES was included to evaluate whether this change differed between neighbourhoods based on SES.

RESULTS

Grocery stores in neighbourhoods in the lowest SES quintile were 39% less likely to start selling alcohol than grocery stores in neighbourhoods in the highest SES quintile (odds ratio (OR): 0.61, 95% confidence interval (CI): 0.39-0.94). As grocery store sales expanded, the distance to the closest off-premise alcohol outlet decreased by 51.8 m annually (95% CI: 48.8-54.9, p < 0.01). A significant interaction between year and SES was observed whereby this trend was more pronounced in high- versus low-SES neighbourhoods.

CONCLUSION

The expansion of grocery store alcohol sales increased alcohol availability, but this increase was proportionately larger in high- versus low-SES neighbourhoods. This reduced historic disparities in alcohol availability between low- and high-SES neighbourhoods.

Alcohol and Public Health: Failure and Opportunity

Policy Points Public health science regarding alcohol consumption and problems, alcohol's role in equity and social justice, and identification of effective policy interventions has grown steadily stronger in the past 30 years. Progress on effective alcohol policies has stalled or gone backward in the United States and much of the world. Because alcohol influences at least 14 of the 17 sustainable development goals, as well as more than 200 disease and injury conditions, reducing alcohol problems should offer a platform for collaboration across public health silos but will require that public health itself respect and follow its own science.

A contextualized reinforcer pathology approach to addiction

Behavioural economic accounts of addiction conceptualize harmful drug use as an operant reinforcer pathology, emphasizing that a drug is consumed because of overvaluation of smaller immediate rewards relative to larger delayed rewards (delay discounting) and high drug reinforcing value (drug demand). These motivational processes are within-individual determinants of behaviour. A third element of learning theory posits that harmful drug use depends on the relative constraints on access to other available activities and commodities in the choice context (alternative reinforcers), reflecting the substantial influence of environmental factors. In this Perspective, we integrate alternative reinforcers into the contemporary behavioural economic account of harmful drug use - the contextualized reinforcer pathology model - and review empirical literature across the translational spectrum in support of this model. Furthermore, we consider how increases in drug-related mortality and health disparities in addiction can be understood and potentially ameliorated via a contextualized reinforcer pathology model in which lack of alternative reinforcement is a major risk factor for addiction.

Neighborhood factors and triple negative breast cancer: The role of cumulative exposure to area-level risk factors

BACKGROUND

Despite similar incidence rates among Black and White women, breast cancer mortality rates are 40% higher among Black women. More than half of the racial difference in breast cancer mortality can be attributed to triple negative breast cancer (TNBC), an aggressive subtype of invasive breast cancer that disproportionately affects Black women. Recent research has implicated neighborhood conditions in the etiology of TNBC. This study investigated the relationship between cumulative neighborhood-level exposures and TNBC risk.

METHODS

This single-institution retrospective study was conducted on a cohort of 3316 breast cancer cases from New Castle County, Delaware (from 2012 to 2020), an area of the country with elevated TNBC rates. Cases were stratified into TNBC and "Non-TNBC" diagnosis and geocoded by residential address. Neighborhood exposures included census tract-level measures of unhealthy alcohol use, metabolic dysfunction, breastfeeding, and environmental hazards. An overall cumulative risk score was calculated based on tract-level exposures.

RESULTS

Univariate analyses showed each tract-level exposure was associated with greater TNBC odds. In multivariate analyses that controlled for patient-level race and age, tract-level exposures were not associated with TNBC odds. However, in a second multivariate model that included patient-level variables and considered tract-level risk factors as a cumulative exposure risk score, each one unit increase in cumulative exposure was significantly associated with a 10% increase in TNBC odds. Higher cumulative exposure risk scores were found in census tracts with relatively high proportions of Black residents.

CONCLUSIONS

Cumulative exposure to neighborhood-level risk factors that disproportionately affect Black communities was associated with greater TNBC risk.

The Association Between Racial Attitudes, Alcohol Use and Mood Disorders Among Black Adolescents

Alcohol is the most widely used substance among adolescents. Although Black adolescents use alcohol at lower rates than White adolescents, Black adolescents tend to have worse outcomes. This includes higher rates of mood disorders and criminal justice involvement associated with alcohol use and misuse compared to any other racial group. Black adolescents are also more likely to experience racial discrimination and be exposed to traumatic events within their communities, which may increase their chances of using substances. Understanding the relationship between racial attitudes (towards one's own group and others) and substance use and mental health can provide unique and meaningful insight into prevention programming for Black adolescents. Yet, these concepts have been understudied. To fill this gap, we examined the association between racial attitudes and alcohol use and mood disorders in Black adolescents in Philadelphia, PA (N = 154). We used the revised Adolescent Survey of Black Life to measure pro-Black (positive attitudes toward being Black and factors related to Black people), anti-White (negative attitudes toward White people due to experiences of racism and discrimination) and racism awareness (recognition of racism) domains. Logistic regression analyses were conducted to test the associations. Results showed that: higher pro-Black attitudes were associated with a lower odds of mood disorder (odds ratio [OR] = 0.72, 95% CI = 0.55, 0.89); and higher racism awareness was associated with an increased odds of alcohol use (OR = 1.18, 95% confidence interval [CI] = 1.06, 1.29). Findings provide preliminary support for interventions and policies for Black adolescents that bolster positive racial identity and eliminate experiences of racism as alcohol use and mood disorder prevention strategies.

Establishing the Relative Accuracy of Using City Directories as Proxies to Define and Reconstruct Historical Alcohol Environments

OBJECTIVE

Research on alcohol environments has established that poorer and minoritized communities are frequently overburdened by off-premise outlets (e.g., liquor stores). These outlets have more associated harms, including increased alcohol consumption and crime rates. Little, if any, research has shown how these socio-spatial disparities in exposure have grown or shifted over time, and no studies have established a method for re-creating historical alcohol environments.

METHOD

Our results suggest that in our study city of Flint, MI, disparities in the alcohol environment have narrowed since 1950. Although liquor stores are still more likely to be located in poorer and more heavily African American neighborhoods, the pattern has become insignificant over time. Furthermore, the number of alcohol outlets per capita has declined. Thus, although the city remains more overburdened with alcohol outlets than its suburbs, the disparity has shrunk.

CONCLUSIONS

This work has implications for those working in alcohol prevention and policy, as well as in urban planning. Practitioners and researchers can use this method to model alcohol availability over time in their own communities, which helps better inform the discussion on disparities experienced in poor and minoritized neighborhoods.

Strategic Directions in Preventive Intervention Research to Advance Health Equity

As commissioned by the Society for Prevention Research, this paper describes and illustrates strategic approaches for reducing health inequities and advancing health equity when adopting an equity-focused approach for applying prevention science evidence-based theory, methodologies, and practices. We introduce an ecosystemic framework as a guide for analyzing, designing, and planning innovative equity-focused evidence-based preventive interventions designed to attain intended health equity outcomes. To advance this process, we introduce a health equity statement for conducting integrative analyses of ecosystemic framework pathways, by describing the role of social determinants, mechanisms, and interventions as factors directly linked to specific health equity outcomes. As background, we present health equity constructs, theories, and research evidence which can inform the design and development of equity-focused intervention approaches. We also describe multi-level interventions that when coordinated can produce synergistic intervention effects across macro, meso, and micro ecological levels. Under this approach, we encourage prevention and implementation scientists to apply and extend these strategic directions in future research to increase our evidence-based knowledge and theory building. A general goal is to apply prevention science knowledge to design, widely disseminate, and implement culturally grounded interventions that incrementally attain specific HE outcomes and an intended HE goal. We conclude with recommendations for conducting equity-focused prevention science research, interventions, and training.

The Relationship of Historical Redlining with Present-Day Neighborhood Environmental and Health Outcomes: A Scoping Review and Conceptual Model

Following the Great Depression and related home foreclosures, the federal government established new agencies to facilitate access to affordable home mortgages, including the Home Owners' Loan Corporation (HOLC) and Federal Housing Administration (FHA). HOLC and FHA directed widespread neighborhood appraisals to determine investment risk, referred to as "redlining," which took into account residents' race. Redlining thereby contributed to segregation, disinvestment, and racial inequities in opportunities for homeownership and wealth accumulation. Recent research examines associations between historical redlining and subsequent environmental determinants of health and health-related outcomes. In this scoping review, we assess the extent of the current body of evidence, the range of outcomes studied, and key study characteristics, examining the direction and strength of the relationship between redlining, neighborhood environments, and health as well as different methodological approaches. Overall, studies nearly universally report evidence of an association between redlining and health-relevant outcomes, although heterogeneity in study design precludes direct comparison of results. We critically consider evidence regarding HOLC's causality and offer a conceptual framework for the relationship between redlining and present-day health. Finally, we point to key directions for future research to improve and broaden understanding of redlining's enduring impact and translate findings into public health and planning practice.

Neighborhood Disadvantage, Patterns of Unhealthy Alcohol Use, and Differential Associations by Gender, Race/Ethnicity, and Rurality: A Study of Veterans Health Administration Patients

OBJECTIVE

Stressful conditions within disadvantaged neighborhoods may shape unhealthy alcohol use and related harms. Yet, associations between neighborhood disadvantage and more severe unhealthy alcohol use are underexplored, particularly for subpopulations. Among national Veterans Health Administration (VA) patients (2013-2017), we assessed associations between neighborhood disadvantage and multiple alcohol-related outcomes and examined moderation by sociodemographic factors.

METHOD

Electronic health record data were extracted for VA patients with a routine Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) screen. Patient addresses were linked by census block group to the Area Deprivation Index (ADI), dichotomized at the 85th percentile, and examined in quintiles for sensitivity analyses. Using modified Poisson generalized estimating equations models, we estimated associations between neighborhood disadvantage and five outcomes: unhealthy alcohol use (AUDIT-C ≥ 5), any past-year heavy episodic drinking (HED), severe unhealthy alcohol use (AUDIT-C ≥ 8), alcohol use disorder (AUD) diagnosis, and alcohol-specific conditions diagnoses. Moderation by gender, race/ethnicity, and rurality was tested using multiplicative interaction.

RESULTS

Among 6,381,033 patients, residence in a highly disadvantaged neighborhood (ADI ≥ 85th percentile) was associated with a higher likelihood of unhealthy alcohol use (prevalence ratio [PR] = 1.06, 95% CI [1.05, 1.07]), severe unhealthy alcohol use (PR = 1.14, 95% CI [1.12, 1.15]), HED (PR = 1.04, 95% CI [1.03, 1.05]), AUD (PR = 1.14, 95% CI [1.13, 1.15]), and alcohol-specific conditions (PR = 1.21, 95% CI [1.18, 1.24]). Associations were larger for Black and American Indian/Alaska Native patients compared with White patients and for urban compared with rural patients. There was mixed evidence of moderation by gender.

CONCLUSIONS

Neighborhood disadvantage may play a role in unhealthy alcohol use in VA patients, particularly those of marginalized racialized groups and those residing in urban areas.

The long shadow of residential racial segregation: Associations between childhood residential segregation trajectories and young adult health among Black US Americans

Residential racial segregation is a key manifestation of anti-Black structural racism, thought to be a fundamental cause of poor health; evidence has shown that it yields neighborhood disinvestment, institutional discrimination, and targeting of unhealthy products like tobacco and alcohol. Yet research on the long-term impacts of childhood exposure to residential racial segregation is limited. Here, we analyzed data on 1823 Black participants in the Panel Study of Income Dynamics, estimating associations between childhood segregation trajectories and young adult health. Black young adults who consistently lived in high-segregation neighborhoods throughout childhood experienced unhealthier smoking and drinking behaviors and higher odds of obesity compared to other trajectory groups, including children who moved into or out of high-segregation neighborhoods. Results were robust to controls for neighborhood and family poverty. Findings underscore that for Black children who grow up in segregated neighborhoods, the roots of structurally-determined health inequities are established early in life.

Redlining, racism and food access in US urban cores

In the 1930s, the Home Owners' Loan Corporation (HOLC) graded the mortgage security of urban US neighborhoods. In doing so, the HOLC engaged in the practice, imbued with racism and xenophobia, of "redlining" neighborhoods deemed "hazardous" for lenders. Redlining has caused persistent social, political and economic problems for communities of color. Linkages between redlining and contemporary food access remain unexamined, even though food access is essential to well-being. To investigate this, we used a census tract-level measure of low-income and low grocery store food access from the US Department of Agriculture Food Access Research Atlas, redlining data from Mapping Inequality Project, and demographic data from the American Community Survey. We employed generalized estimating equations with robust covariance estimates to analyze data pertaining to 10,459 census tracts in 202 US cities. Tracts that the HOLC graded as "C" ("decline in desirability") and "D" ("hazardous") had reduced contemporary food access compared to those graded "A" ("best"). Increases in contemporary census tract proportions of Black, Hispanic, or other racial/ethnic minority residents, as well as disabled residents, were associated with reduced food access. Increases in contemporary proportions of residents age 75 years and older or those without a car were associated with better food access. Tracts that underwent housing redevelopment since being graded had better food access, while those undergoing gentrification had reduced food access. Results suggest that issues of redlining, housing discrimination, racism, ableism, displacement, and food inaccessibility are deeply intertwined.

Historical redlining and food environments: A study of 102 urban areas in the United States

OBJECTIVE

Unhealthy food environments are disproportionally concentrated in neighborhoods with clustering of racial/ethnic minorities and poverty. This disparity has been blamed, in part, on market self-regulation. This explanation risks overlooking past and current practices of racial segregation that have created and reinforced the obstacles blocking investments from food retailers in marginalized neighborhoods. We fill this gap by investigating how the long-term ramifications of redlining, discriminatory housing practices enacted by federal Home Owner Lending Corporation (HOLC) in the 1930s, has evolved generations later to disproportionally exposing neighborhoods to unhealthy food environments.

METHODS

We overlaid historical redlining maps over 2010 food environment observations at the census tract level to identify areas with less healthy food environments and to assess the historical context of those areas. For 11,651 census tracts within 102 U.S. urban areas, we described the healthiness of food environments as measured by the modified retail food environment index (mRFEI). Using hurdle models with random effects, we further examined the association between redlining housing practice and food environments.

RESULTS

The results indicate that historically redlined neighborhoods show a higher likelihood for unhealthy retail food environments even for census tracts with present-day economic and racial privilege.

CONCLUSION

The current evidence shows how structural discrimination manifested by unjust housing practices and racial residential segregation fueled an uneven food environment where minority neighborhoods disproportionally bore the brunt of restrictive food access. It highlights an urgent need to ameliorate patterns of housing inequality as a fix to unequal food environments.

Spatially Varying Associations of Neighborhood Disadvantage with Alcohol and Tobacco Retail Outlet Rates

More than 30% of cancer related deaths are related to tobacco or alcohol use. Controlling and restricting access to these cancer-causing products, especially in communities where there is a high prevalence of other cancer risk factors, has the potential to improve population health and reduce the risk of specific cancers associated with these substances in more vulnerable population subgroups. One policy-driven method of reducing access to these cancer-causing substances is to regulate where these products are sold through the placement and density of businesses selling tobacco and alcohol. Previous work has found significant positive associations between tobacco, alcohol, and tobacco and alcohol retail outlets (TRO, ARO, TARO) and a neighborhood disadvantage index (NDI) using Bayesian shared component index modeling, where NDI associations differed across outlet types and relative risks varied by population density (e.g., rural, suburban, urban). In this paper, we used a novel Bayesian index model with spatially varying effects to explore spatial nonstationarity in NDI effects for TROs, AROs, and TAROs across census tracts in North Carolina. The results revealed substantial variation in NDI effects that varied by outlet type. However, all outlet types had strong positive effects in one coastal area. The most important variables in the NDI were percent renters, Black racial segregation, and the percentage of homes built before 1940. Overall, more disadvantaged areas experienced a greater neighborhood burden of outlets selling one or both of alcohol and tobacco.

Sustainable Development of Life Service Resources: A New Framework Based on GIScience and Spatial Justice

The sustainable development goals (SDGs) reflect the pursuit of achieving spatial justice. Both SDG 1.4 and SDG 11.1 reflect a concern for urban services. Life service resources, which are the new concept proposed by the Chinese government, also call for sustainable development path. However, few studies have focused on the realization of spatial justice in life service resources. This paper proposes a two-level, four-step analysis framework composed of quantity, structure, pattern, and coupling coordination to perceive the spatial justice of life service resources. Based on remote sensing technology and geographic information science, this paper acquires and analyses multi-source data including population density, building outlines, point of interests, subway lines, etc. Furthermore, the case study in downtown Beijing found the following: (1) The total life service resources are extensive and varying in type; (2) regional differences are evident and low-level equilibrium and high-level priority development coexist; (3) life service resources are concentrated in contiguous and multi-centre clusters with a greater north–south than east–west difference; (4) the overall level of life service resources is low, specifically for “high in the centre and low in the periphery” and “high in the east and low in the west”. Future management should consider narrowing the development gap and formulating industry development plans to improve spatial justice. Finally, the comparison between Beijing and London and more cities in the future needs to consider the urban development stage, population density, and other aspects.

The Index of Concentration at the Extremes (ICE) and Pregnancy-Associated Mortality in Louisiana, 2016-2017

OBJECTIVES

Social and contextual factors underlying the continually disproportionate and burdensome risk of adverse health outcomes experienced by Black women in the US are underexplored in the literature. The aim of this study was to use an index based on area-level population distributions of race and income to predict risk of death during pregnancy and up to 1 year postpartum among women in Louisiana.

METHODS

Using vital records data provided by the Louisiana Department of Health 2016-2017 (n = 125,537), a modified Poisson model was fit with generalized estimating equations to examine the risk of pregnancy-associated death associated with census tract-level values of the Index of Concentration at the Extremes (ICE)-grouped by tertile-while adjusting for both individual and tract-level confounders.

RESULTS

Analyses resulted in an estimated 1.73 (95% CI 1.02-2.93) times increased risk for pregnancy-associated death for those in areas which were characterized by concentrated deprivation (high proportions of Black and low-income residents) relative to those in areas of concentrated privilege (high proportions of white and high-income residents), independent of other factors.

CONCLUSIONS FOR PRACTICE

In addition to continuing to consider the deeply entrenched racism and economic inequality that shape the experience of pregnancy-associated death, we must also consider their synergistic effect on access to resources, maternal population health, and health inequities.

Associations of Alcohol and Tobacco Retail Outlet Rates with Neighborhood Disadvantage

Tobacco causes 29% of cancer-related deaths while alcohol causes 5.5% of cancer-related deaths. Reducing the consumption of these cancer-causing products is a special priority area for the National Cancer Institute. While many factors are linked to tobacco and alcohol use, the placement and density of retail outlets within neighborhoods may be one community-level risk factor contributing to greater use of these products. To elucidate associations between tobacco, alcohol, and tobacco and alcohol retail outlets (TRO, ARO, and TARO) and neighborhood disadvantage over a large geographic area, we employed a novel Bayesian index modeling approach to estimate a neighborhood disadvantage index (NDI) and its associations with rates of the three types of retailers across block groups in the state of North Carolina. We used a novel extension of the Bayesian index model to include a shared component for the spatial pattern common to all three types of outlets and NDI effects that varied by outlet type. The shared component identifies areas that are elevated in risk for all outlets. The results showed significant positive associations between neighborhood disadvantage and TROs (relative risk (RR) = 1.12, 95% credible interval (CI = 1.09, 1.14)) and AROs (RR = 1.15, 95% CI = 1.11, 1.17), but the association was greatest for TAROs (RR = 1.21, 95% CI = 1.18, 1.24). The most important variables in the NDI were percent renters (i.e., low home ownership), percent of homes built before 1940 (i.e., old housing stock), and percent without a high school diploma (i.e., low education).

Racial disparities in triple negative breast cancer: toward a causal architecture approach

BACKGROUND

Triple negative breast cancer (TNBC) is an aggressive subtype of invasive breast cancer that disproportionately affects Black women and contributes to racial disparities in breast cancer mortality. Prior research has suggested that neighborhood effects may contribute to this disparity beyond individual risk factors.

METHODS

The sample included a cohort of 3316 breast cancer cases diagnosed between 2012 and 2020 in New Castle County, Delaware, a geographic region of the US with elevated rates of TNBC. Multilevel methods and geospatial mapping evaluated whether the race, income, and race/income versions of the neighborhood Index of Concentration at the Extremes (ICE) metric could efficiently identify census tracts (CT) with higher odds of TNBC relative to other forms of invasive breast cancer. Odds ratios (OR) and 95% confidence intervals (CI) were reported; p-values < 0.05 were significant. Additional analyses examined area-level differences in exposure to metabolic risk factors, including unhealthy alcohol use and obesity.

RESULTS

The ICE-Race, -Income-, and Race/Income metrics were each associated with greater census tract odds of TNBC on a bivariate basis. However, only ICE-Race was significantly associated with higher odds of TNBC after adjustment for patient-level age and race (most disadvantaged CT: OR = 2.09; 95% CI 1.40-3.13), providing support for neighborhood effects. Higher counts of alcohol and fast-food retailers, and correspondingly higher rates of unhealthy alcohol use and obesity, were observed in CTs that were classified into the most disadvantaged ICE-Race quintile and had the highest odds of TNBC.

CONCLUSION

The use of ICE can facilitate the monitoring of cancer inequities and advance the study of racial disparities in breast cancer.

Individual and Community Social Determinants of Health and Recovery from Alcohol Use Disorder Three Years following Treatment

Prior research on recovery from alcohol use disorder (AUD) has often focused on individual-level factors that promote recovery. Given systemic health inequities, it is also important to study community-level social determinants of health (SDOH) that may promote recovery from AUD. This study extended prior work examining individual profiles of recovery from AUD to assess how individual and community SDOH at the time of treatment entry were associated with recovery from AUD three years after treatment. Data were utilized from the COMBINE study (n = 664), a multisite randomized clinical trial evaluating pharmacological and behavioral treatments for AUD. Public community data sources associated with participants' study sites were used to measure community SDOH. Multilevel latent profile analyses with individual- and community-level variables as predictors of recovery profiles were estimated. Four profiles were identified based on participants' alcohol consumption and functioning. Individual SDOH variables, such as fewer years of education and lower income, and community SDOH, including lower rates of health insurance, lower income, and greater income inequality, were each associated with lower functioning profiles. The findings highlight the importance of community SDOH in AUD recovery and the value of including both individual and community SDOH variables in research on long-term recovery.
