No Room to Fall: Criminal Justice Contact and Neighborhood Disadvantage

Abstract Neighborhoods across the United States are shaped by the criminal justice system and socioeconomic inequality. This article examines whether multiple forms of criminal justice contact affect neighborhood attainment for a cohort of young adults coming of age in the era of mass incarceration. Using the National Longitudinal Survey of Youth, 1997 cohort, and census data, I analyze neighborhood conditions before and after contact with the criminal justice system. Conviction is a critical experience in the life course. Having a household member incarcerated is associated with moving to a worse neighborhood only for White young adults. I contextualize these findings in the literature on the cumulative disadvantages faced by the justice-involved population and the complexities of identifying causal effects for this population. For many, incarceration represents a late stage of criminal justice contact, at which point there is no room to fall. Disentangling the web of disadvantage that follows criminal justice contact is crucial as the effects of the era of mass incarceration continue to accumulate. Locational attainment contextualized within the life course must be central to understanding how the legal system creates and reproduces disadvantage.

Association between neighborhood poverty and ovarian reserve: the ovarian aging study.

This study aimed to examine the association between neighborhood poverty and ovarian reserve. Among 1,019 healthy premenopausal women in the Ovarian Aging Study, aggregate exposure to neighborhood poverty was examined in relation to biomarkers of ovarian reserve, antimüllerian hormone (AMH) and antral follicle count (AFC). Specifically, the interaction of age-x-neighborhood poverty was assessed cross-sectionally to determine whether AMH and AFC declines across women may be greater in women exposed to more neighborhood poverty. Neighborhood poverty was assessed by geocoding and linking women's residential addresses in adulthood to US Census data. Independent of covariates, a significant interaction term showed the association between age and AMH varied by degree of exposure to neighborhood poverty in adulthood ( b = -0.001, P < 0.05). AMH declines increased progressively across women exposed to low, medium, and high levels of neighborhood poverty. In addition, main effects showed that higher neighborhood poverty was related to higher AMH in the younger women only ( b = 0.022, P < 0.01). Results related to AFC were all nonsignificant ( P > 0.05). Across women, greater aggregate exposure to neighborhood poverty in adulthood was related to lower ovarian reserve, indexed by AMH. In addition, there was a positive association between neighborhood poverty and AMH in younger women that attenuated in the older women. Together, results suggest that neighborhood disadvantage may have detrimental impacts that manifest as initially higher AMH, resulting in greater ovarian follicle loss over time. However, it remains unclear whether these results examining differences across women may replicate when AMH declines by neighborhood poverty are examined longitudinally.

Exploring the impacts of neighborhood disadvantage on Medicare beneficiaries’ early COVID-19 vaccine uptake

A variety of factors influenced the American public's experiences with the COVID-19 pandemic and initial availability and uptake of COVID-19 vaccines. To examine variation in early COVID-19 vaccine uptake based on neighborhood disadvantage along with individual sociodemographic and health characteristics, we used Spring 2021 data from the Medicare Current Beneficiary Survey (MCBS), a nationally representative, longitudinal survey of the Medicare population conducted by the Centers for Medicare & Medicaid Services. Bivariate analyses showed that beneficiaries in disadvantaged neighborhoods were less likely to have received at least one vaccine dose than those in less disadvantaged neighborhoods (49.7%, SE = 1.6 versus 66.6%, SE = 1.0, p < 0.0001). After accounting for individual characteristics, the relationship between neighborhood disadvantage and vaccine uptake was not statistically significant. However, interaction effects of neighborhood disadvantage by urbanicity showed a more complex picture, where those in disadvantaged urban areas had the lowest odds of vaccine uptake (p < 0.01). The relationship between neighborhood disadvantage and vaccination is multifaceted, requiring further research to inform future vaccination efforts targeting the most vulnerable beneficiaries.

La disputa por el barrio popular en el imaginario neoliberal de Argentina (2000-2015): el mito de la Villa y sus alternativas

Abstract: This article analyses the narratives around the slums in Argentina during the beginning of the XXI century. In this period, movies, books and other cultural objects thematized the most disadvantaged neighborhoods. Although very different in content and form, they concluded by segregating and dehumanizing the citizens of the slums. However, there were also alternative voices that disputed the hegemonic imaginary. For the first time in history, neighbors from the slums started to publish books and film movies. Not only did this production defy how culture is produced and circulated, but also seized the narratives around their own neighborhoods.

Parental Attachment and Psychosocial Adjustment in Adolescents Exposed to Marital Conflict.

(1) Background: Interparental conflict is a phenomenon that poses a serious threat not only to the quality of life of the couple but also to the father-child relationship, mother-child relationship, and well-being of adolescents. This study examined the difference in parental attachment and adjustment in adolescents exposed to marital conflict versus those not exposed to parental conflicts in low-income areas. (2) Methods: 67 adolescents involved in Child Welfare Services (CWS) in disadvantaged neighbourhoods in southern Spain were examined. The sample was split into two groups according to the exposure to marital conflict. Subsequently, differences between groups were analysed on father attachment, mother attachment, aggression, antisocial behaviour, and emotional intelligence. (3) Results: Primarily, the data showed significantly worse attachment with the father among conflict-exposed versus non-conflict-exposed adolescents. These results were not found for the attachment with the mother. Additionally, greater anger and worse stress management were found in conflict-exposed adolescents. (4) Conclusions: The results partially confirmed the spillover and compensatory hypothesis. Practical implications point out that developing preventive interventions that protect the father-adolescent attachment in situations of family conflict is recommended.

Understanding parental perspectives on young children's oral health (≤ 4 years) growing up in a disadvantaged neighbourhood of Amsterdam, the Netherlands: an exploratory study.

Families' understanding towards oral health problems among young children is poorly studied. More insight into parents' experiences, especially of those living in disadvantaged neighbourhoods, is needed to address persistent oral health inequalities. This qualitative study aims to explore parental perspectives on children's oral health (≤ 4 years) and the opportunities they see to improve children's oral health. Forty-seven mothers and five fathers with different migration backgrounds from a disadvantaged neighbourhood in Amsterdam, the Netherlands, participated in our study. Semi-structured interviews (n = 27), participant observations (n = 7) and one focus group discussion were conducted. A thematic data analysis was used. Parents describe their daily life with young children as busy, hectic and unpredictable. Parents seem to be most concerned about parenting. Mothers, in particular, feel fully responsible for raising their children and managing daily complexities. While most parents value their children's oral health, they all experience challenges. Parents find it hard to limit daily candy intake and to handle unwilling children during tooth brushing. They feel limited support for these issues from their household, social network and professionals. Parental struggles in children's oral health are complex and interrelated as they occur across family, societal, community and professional levels. Given the complex daily reality of families with young children, establishing and maintaining healthy oral health habits seems not at the top of parents' minds. They ask for advice in the upbringing of their children backed up by social support, increased attention to children's oral health within the community and professional assistance. Collaborating with parents as knowledgeable partners might be the first step in acting upon the endeavour to address oral health inequality among young children.

Neighborhood disadvantage reduces cognitive reserve independent of neuropathologic change.

Individuals in socioeconomically disadvantaged neighborhoods exhibit increased risk for impaired cognitive function. Whether this association relates to the major dementia-related neuropathologies is unknown. This cross-sectional study included 469 autopsy cases from 2011 to 2023. The relationships between neighborhood disadvantage measured by Area Deprivation Index (ADI) percentiles categorized into tertiles, cognition evaluated by the last Mini-Mental State Examination (MMSE) scores before death, and 10 dementia-associated proteinopathies and cerebrovascular disease were assessed using regression analyses. Higher ADI was significantly associated with lower MMSE score. This was mitigated by increasing years of education. ADI was not associated with an increase in dementia-associated neuropathologic change. Moreover, the significant association between ADI and cognition remained even after controlling for changes in major dementia-associated proteinopathies or cerebrovascular disease. Neighborhood disadvantage appears to be associated with decreased cognitive reserve. This association is modified by education but is independent of the major dementia-associated neuropathologies.

Evaluation of the “Build your bike!” pilot project by and for disadvantaged youth: A school-based intervention to promote active mobility

The densification of urban centers has driven individuals with low income toward more affordable suburban neighborhoods, thereby constraining transportation options due to car-centric planning and the difficulty for public transit systems to meet mobility needs. Recognizing that active cycling promotes travel autonomy, social participation, and physical and mental well-being, the promotion of such behavior through localized interventions stands as a critical objective to foster transport equity. In this context, in collaboration with the organization “Cyclo Nord-Sud,” this study aims to explore the outcomes and favorable components of the “Build Your Bike!” pilot project offered as an extracurricular activity to high school students in a disadvantaged neighborhood. A qualitative, comprehensive approach with an inductive and phenomenological perspective was employed. We conducted a focus group at the end of the program and used conceptual categories to complete the analysis. The results revealed positive outcomes from the program related to: 1) well-being, 2) learning, 3) access to a bicycle, and 4) mobility. Favorable mechanisms encompassed: 1) the approach of adult mentors, 2) extracurricular involvement, 3) teamwork, 4) manual labor, and 5) bicycle ownership upon program completion. The mechanisms identified by the participants hold potential for improvement in future program iterations and can guide the development of similar interventions.

Neighbourhood structure and environmental quality: A fine-grained analysis of spatial inequalities in urban Germany

Urban environments are characterised by sparsity of space, elevated levels of air pollution and limited exposure to natural environments. Yet, residential environmental quality varies substantially both between and within cities. This study combines information on the socio-economic and demographic composition of 243,607 urban neighbourhoods with administrative and remote sensing data on the spatial distribution of industrial plants and urban green space to investigate patterns of environmental inequality in urban Germany at unprecedented levels of spatial granularity. It disentangles neighbourhood disadvantages experienced by foreign minorities (non-nationals) from those experienced by low-income households in order to assess the plausibility of economic explanations of residential sorting. The high level of spatial granularity makes it possible to examine patterns of environmental inequality not only between the relatively large areas that have been used as units of analysis in previous work but also within them, while reducing the threat of ecological bias. Results indicate that non-nationals are more likely to be exposed to industrial air pollution and less likely to live close to green spaces. This association holds even after adjusting for neighbourhood income composition and in fixed-effects specifications that restrict the analysis to within-city variation. I find no evidence for environmental inequality by socio-economic status. Exploratory sub-sample analyses show that neighbourhood disadvantages for non-nationals are higher in cities characterised by high levels of anti-foreigner sentiment, pointing towards housing market discrimination as a potentially important driver of foreign residents’ neighbourhood disadvantage.

Health care disparities and chronic rhinosinusitis: Does neighborhood disadvantage impact outcomes in sinonasal disease?

Socioeconomic status (SES) is linked to health outcomes but has not been well studied in patients with chronic rhinosinusitis (CRS). The area deprivation index (ADI) is a comprehensive measure of geographic SES that ranks neighborhood disadvantage. This investigation used ADI to understand the impact of neighborhood disadvantage on CRS treatment outcomes. A total of 642 study participants with CRS were prospectively enrolled and self-selected endoscopic sinus surgery (ESS) or continued appropriate medical therapy as treatment. The 22-item SinoNasal Outcome Test (SNOT-22) and Medical Outcomes Study Questionnaire Short-Form 6-D (SF-6D) health utility value scores were recorded pre- and post-treatment. Using residence zip codes, national ADI scores were retrospectively assigned to patients. Spearman's correlation coefficients (Rs) and Cramer's V effect size (φc) with 95% confidence interval (CI) were calculated. A history of ESS was associated with significantly worse ADI scores compared to no history of ESS (φc=0.18; 95% CI: 0.10, 0.25; p<0.001). Baseline total SNOT-22 (Rs=0.14; 95% CI: 0.06, 0.22; p<0.001) and SF-6D values (Rs=-0.20; 95% CI: -0.27, -0.12; p<0.001) were significantly negatively correlated with national ADI rank. No significant correlations between ADI and within-subject improvement, or achievement of>1 minimal clinically important difference, in SNOT-22 or SF-6D scores after treatment were found. Geographic socioeconomic deprivation was associated with worse baseline disease severity and history of prior surgical intervention. However, ADI did not correlate with improvement in disease-specific outcomes. The impact of socioeconomic deprivation on outcomes in CRS requires further investigation.

Disparities in Provider Ordering Practices of Image-Guided Interventions and Surgery for Patients With Low Back Pain: A Cohort Study

ObjectiveTo assess individual- and neighborhood-level sociodemographic factors associating with providers’ ordering of nonpharmacologic treatments for patients with low back pain (LBP), specifically physical therapy, image-guided interventions, and lumbar surgery. MethodsOur cohort included all patients diagnosed with LBP from 2000 to 2017 in a statewide database of all hospitals and ambulatory surgical facilities within Utah. We compared sociodemographic and clinical characteristics of (1) patients with LBP who received any treatment with those who received none and (2) patients with LBP who received invasive LBP treatments with those who only received noninvasive LBP treatments using the Student’s t test, Wilcoxon’s rank-sum tests, and Pearson’s χ2 tests, as applicable, and two separate multivariate logistic regression models: (1) to determine whether sociodemographic characteristics were risk factors for receiving any LBP treatments and (2) risk factors for receiving invasive LBP treatments. ResultsIndividuals in the most disadvantaged neighborhoods were less likely to receive any nonpharmacologic treatment orders (odds ratio [OR] 0.74 for most disadvantaged, P < .001) and received fewer invasive therapies (0.92, P = .018). Individual-level characteristics correlating with lower rates of treatment orders were female sex, Native Hawaiian or other Pacific Islander race (OR 0.50, P < .001), Hispanic ethnicity (OR 0.77, P < .001), single or unmarried status (OR 0.69, P < .001), and no insurance or self-pay (OR 0.07, P < .001). ConclusionNeighborhood and individual sociodemographic variables associated with treatment orders for LBP with Area Deprivation Index, sex, race or ethnicity, insurance, and marital status associating with receipt of any treatment, as well as more invasive image-guided interventions and surgery.

Nudging plant-based alternatives to meat and dairy in a real-life online supermarket: A randomized controlled trial

A shift from predominantly animal-based to plant-based consumption can benefit both planetary and public health. Nudging may help to promote such a shift. This study investigated nudge effects on plant-based alternatives to meat and dairy in an online supermarket. We conducted a two-arm, parallel-group, randomized controlled real-life online supermarket trial. Each customer transaction was randomized to a control arm (regular online supermarket) or an intervention arm (addition of placement, hedonic property and dynamic social norm nudges promoting meat and dairy alternatives). Outcomes were the aggregate of meat and dairy alternative purchases (primary outcome), the number of meat purchases, dairy purchases, meat alternative purchases, and dairy alternative purchases (secondary), and retailer revenue (tertiary). Generalized linear mixed models with a Conway–Maxwell Poisson distribution were used to estimate incidence rate ratios (IRRs). Analyzed data included 8488 transactions by participants (n = 4,266 control arm, n = 4,222 intervention arm), out of which 2,411 (66%) were aged above 45 years, 5,660 (67%) were females, and 1,970 (23%) lived in socially disadvantaged neighborhoods. Intervention arm participants purchased 10% (IRR 1.10 (95% CI 0.99–1.23)) more meat and dairy alternatives and 16% (1.16 (0.99–1.36)) more meat alternatives than control arm participants, although these findings are not statistically significant. There was no difference in dairy alternative purchases (1.00 (0.90–1.10)). Intervention arm participants purchased 3% less meats (0.97 (0.93–1.02)) and 2% less dairy products (0.98 (0.95–1.02)) than control participants. Retailer revenue was not affected (0.98 (0.95–1.01)). Online nudging strategies alone did not lead to a statistically significant higher amount of plant-based purchases, but replication of this work is needed with increased study power. Future studies should also consider nudging strategies as part of a broader set of policies to promote plant-based purchases. Trial registrationProspectively registered on 14th of May 2022.

Exposure to Neighborhood Violence and Gun Carrying Among Adolescents in the United States: Findings From A Population-Based Study.

Although studies have investigated and found an association between victimization and weapon carrying, few studies have examined the association between exposure to neighborhood violence (NV) and gun carrying among adolescents. The objective of this study was to examine the cross-sectional association between exposure to NV and gun carrying among adolescents. Data for this study came from the 2021 Youth Risk Behavior Survey. An analytic sample of 17,033 adolescents aged 14 to 18 years old (51.7% male) was analyzed using logistic regression with complementary log-log link function. The outcome variable investigated in this study is gun carrying and was measured as a binary variable, whereas the main explanatory variable examined in this study was exposure to NV, which was also measured as a binary variable. Of the 17,033 adolescents, 4.2% carried a weapon during the past year, and 18.7% were exposed to NV. Controlling for the effects of other factors, adolescents who were exposed to NV had more than double the odds of carrying a gun when compared to their counterparts not exposed to NV (adjusted odds ratio = 2.33, 95% Confidence Intervals [1.69, 3.23]). Other significant factors associated with gun carrying include being a male, non-Hispanic Black, being threatened or injured with a weapon, use of alcohol, cigarette smoking, and misuse of prescription opioids. High parental monitoring was protective against gun carrying. The findings of this study underscore the importance of developing age-appropriate intervention strategies to reduce gun carrying among adolescents. School counselors and other professionals working with adolescents in disadvantaged neighborhoods should actively engage parents in assessments and interventions.

Neighborhood Disadvantage and Risk of Heart Failure: The Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study.

Heart failure (HF) affects >6 million US adults, with recent increases in HF hospitalizations. We aimed to investigate the association between neighborhood disadvantage and incident HF events and potential differences by diabetes status. We included 23 645 participants from the REGARDS study (Reasons for Geographic and Racial Differences in Stroke), a prospective cohort of Black and White adults aged ≥45 years living in the continental United States (baseline 2005-2007). Neighborhood disadvantage was assessed using a Z score of 6 census tract variables (2000 US Census) and categorized as quartiles. Incident HF hospitalizations or HF-related deaths through 2017 were adjudicated. Multivariable-adjusted Cox regression was used to examine the association between neighborhood disadvantage and incident HF. Heterogeneity by diabetes was assessed using an interaction term. The mean age was 64.4 years, 39.5% were Black adults, 54.9% females, and 18.8% had diabetes. During a median follow-up of 10.7 years, there were 1125 incident HF events with an incidence rate of 3.3 (quartile 1), 4.7 (quartile 2), 5.2 (quartile 3), and 6.0 (quartile 4) per 1000 person-years. Compared to adults living in the most advantaged neighborhoods (quartile 1), those living in neighborhoods in quartiles 2, 3, and 4 (most disadvantaged) had 1.30 (95% CI, 1.06-1.60), 1.36 (95% CI, 1.11-1.66), and 1.45 (95% CI, 1.18-1.79) times greater hazard of incident HF even after accounting for known confounders. This association did not significantly differ by diabetes status (interaction P=0.59). For adults with diabetes, the adjusted incident HF hazards comparing those in quartile 4 versus quartile 1 was 1.34 (95% CI, 0.92-1.96), and it was 1.50 (95% CI, 1.16-1.94) for adults without diabetes. In this large contemporaneous prospective cohort, neighborhood disadvantage was associated with an increased risk of incident HF events. This increase in HF risk did not differ by diabetes status. Addressing social, economic, and structural factors at the neighborhood level may impact HF prevention.

Does the Low-Income Housing Tax Credit Program Expand Access to Opportunity Neighborhoods? Tracking Movements of Low-Income Tenants in California

The Low-Income Housing Tax Credit (LIHTC) program can potentially help expand access to neighborhoods with low poverty and economic opportunities for low-income households. Prior studies described that LIHTC units are in neighborhoods with relatively high poverty, but with improvements in recent years. Beyond cross-sectional analyses, scholars have not extensively looked at the movements of tenants. It remains unclear whether the program creates opportunities for low-income households to move into better neighborhoods than they previously lived in or reinforces segregation by encouraging moves to similarly or more disadvantaged neighborhoods. Using an extensive consumer database, I am tracking the movements of households who move into new LIHTC properties in California. The experimental findings show that residents experience, on average, increases in poverty exposure by up to six percentage points over other moved low-income renters. Tenants see lower levels of neighborhood amenities than at their previous addresses. The construction of LIHTC housing can increase the chance of households moving into minority-concentrated areas.

Evidence of COVID-19 fatalities in Swedish neighborhoods from a full population study

The COVID-19 pandemic has highlighted a debate about whether marginalized communities suffered the disproportionate brunt of the pandemic’s mortality. Empirical studies addressing this question typically suffer from statistical uncertainties and potential biases associated with uneven and incomplete reporting. We use geo-coded micro-level data for the entire population of Sweden to analyze how local neighborhood characteristics affect the likelihood of dying with COVID-19 at individual level, given the individual’s overall risk of death. We control for several individual and regional characteristics to compare the results in specific communities to overall death patterns in Sweden during 2020. When accounting for the probability to die of any cause, we find that individuals residing in socioeconomically disadvantaged neighborhoods were not more likely to die with COVID-19 than individuals residing elsewhere. Importantly, we do find that individuals show a generally higher probability of death in these neighborhoods. Nevertheless, ethnicity is an important explanatory factor for COVID-19 deaths for foreign-born individuals, especially from East Africa, who are more likely to pass away regardless of residential neighborhood.

Real-world nudging, pricing, and mobile physical activity coaching was insufficient to improve lifestyle behaviours and cardiometabolic health: the Supreme Nudge parallel cluster-randomised controlled supermarket trial

BackgroundContext-specific interventions may contribute to sustained behaviour change and improved health outcomes. We evaluated the real-world effects of supermarket nudging and pricing strategies and mobile physical activity coaching on diet quality, food-purchasing behaviour, walking behaviour, and cardiometabolic risk markers.MethodsThis parallel cluster-randomised controlled trial included supermarkets in socially disadvantaged neighbourhoods across the Netherlands with regular shoppers aged 30–80 years. Supermarkets were randomised to receive co-created nudging and pricing strategies promoting healthier purchasing (N = 6) or not (N = 6). Nudges targeted 9% of supermarket products and pricing strategies 3%. Subsequently, participants were individually randomised to a control (step counter app) or intervention arm (step counter and mobile coaching app) to promote walking. The primary outcome was the average change in diet quality (low (0) to high (150)) over all follow-up time points measured with a validated 40-item food frequency questionnaire at baseline and 3, 6, and 12 months. Secondary outcomes included healthier food purchasing (loyalty card-derived), daily step count (step counter app), cardiometabolic risk markers (lipid profile and HbA1c via finger prick, and waist circumference via measuring tape), and supermarket customer satisfaction (questionnaire-based: very unsatisfied (1) to very satisfied (7)), evaluated using linear mixed-models. Healthy supermarket sales (an exploratory outcome) were analysed via controlled interrupted time series analyses.ResultsOf 361 participants (162 intervention, 199 control), 73% were female, the average age was 58 (SD 11) years, and 42% were highly educated. Compared to the control arm, the intervention arm showed no statistically significant average changes over time in diet quality (β − 1.1 (95% CI − 3.8 to 1.7)), percentage healthy purchasing (β 0.7 ( − 2.7 to 4.0)), step count (β − 124.0 (− 723.1 to 475.1), or any of the cardiometabolic risk markers. Participants in the intervention arm scored 0.3 points (0.1 to 0.5) higher on customer satisfaction on average over time. Supermarket-level sales were unaffected (β − 0.0 (− 0.0 to 0.0)).ConclusionsCo-created nudging and pricing strategies that predominantly targeted healthy products via nudges were unable to increase healthier food purchases and intake nor improve cardiometabolic health. The mobile coaching intervention did not affect step count. Governmental policy measures are needed to ensure more impactful supermarket modifications that promote healthier purchases.Trial registrationDutch Trial Register ID NL7064, 30 May 2018, https://www.onderzoekmetmensen.nl/en/trial/20990

Abstract TP103: Association Between Neighborhood-Level Disadvantage and Patient-Reported Mental Health Outcomes in Intracerebral Hemorrhage Survivors

Introduction: The influence of social determinants of health (SDH) is well-documented across a range of medical conditions and health outcomes. Less clear is the impact of SDH on patient-reported outcomes, particularly mental health outcomes, in intracerebral hemorrhage (ICH). This study examines the association between the Area Deprivation Index (ADI), a measure of neighborhood-level disadvantage, and self-reported health outcomes in ICH survivors. Methods: This investigation is nested within the REDUCE clinical trial, an ongoing, randomized trial comparing standard-of-care to spironolactone-containing hypertension regimens in ICH survivors. Participants complete the PROMIS Global Health survey at baseline. Global Mental Health (GMH) and Global Physical Health (GPH) scores are standardized to t-scores (GMH 21.2-67.6; GPH 16.2-67.7) around a reference population mean (50 ± 10). ADI uses elements of income, education, employment, and housing quality to assign a composite score (1-100), with a higher score signifying greater disadvantage. Patients were grouped into tertiles based on ADI. GMH and GPH scores were analyzed against the reference mean via a one-sample t-test and across tertiles with a one-way ANOVA. Bivariable linear regression examined ADI as a continuous variable. Multivariable models adjusted for sex, age, race, ethnicity, ICH to baseline interval, and baseline mRS. Results: Fifty patients were included in the analysis. Those in the third, most disadvantaged, tertile had significantly lower GMH scores (39.5 ± 8.17) than the reference population (p&lt;0.001), the first tertile (54.10 ± 10.20, p&lt;0.001), and the second tertile (50.4 ± 8.90, p=0.003). In multivariable analysis, these differences remained significant (T3 vs. T1, B= -18.31, p&lt;0.001; T3 vs. T2, B= -14.67, p&lt;0.001). Further, ADI as a continuous variable was significantly associated with GMH scores in bivariable (B= -0.22, p&lt;0.001) and multivariable analysis (B= -0.23, p=0.005). No significant relationship was found between ADI and GPH. Conclusions: Higher ADI is associated with worse patient-reported mental health outcomes after ICH. Neighborhood disadvantage, and its constituting factors, should be considered in reporting post-ICH patient care and outcomes.

Mitigating allocative tradeoffs and harms in an environmental justice data tool

Neighbourhood-level screening algorithms are increasingly being deployed to inform policy decisions. However, their potential for harm remains unclear: algorithmic decision-making has broadly fallen under scrutiny for disproportionate harm to marginalized groups, yet opaque methodology and proprietary data limit the generalizability of algorithmic audits. Here we leverage publicly available data to fully reproduce and audit a large-scale algorithm known as CalEnviroScreen, designed to promote environmental justice and guide public funding by identifying disadvantaged neighbourhoods. We observe the model to be both highly sensitive to subjective model specifications and financially consequential, estimating the effect of its positive designations as a 104% (62–145%) increase in funding, equivalent to US$2.08 billion (US$1.56–2.41 billion) over four years. We further observe allocative tradeoffs and susceptibility to manipulation, raising ethical concerns. We recommend incorporating technical strategies to mitigate allocative harm and accountability mechanisms to prevent misuse.

Impact of 2009 American Recovery and Reinvestment Act (ARRA) health center investments on disadvantaged neighborhoods after recession

BackgroundFederally qualified health centers (FQHCs) are integral to the U.S. healthcare safety net and uniquely situated in disadvantaged neighborhoods. The 2009 American Recovery and Reinvestment Act (ARRA) invested $2 billion in FQHC stimulus during the Great Recession; but it remains unknown whether this investment was associated with extended benefits for disadvantaged neighborhoods.MethodsWe used a propensity-score matched longitudinal design (2008–2012) to examine whether the 2009 ARRA FQHC investment was associated with local jobs and establishments recovery in FQHC neighborhoods. Job change data were obtained from the Longitudinal Employer-Household Dynamics (LEHD) survey and calculated as an annual rate per 1,000 population. Establishment change data were obtained from the National Neighborhood Data Archive (NaNDA) and calculated as an annual rate per 10,000 population. Establishment data included 4 establishment types: healthcare services, eating/drinking places, retail establishments, and grocery stores. Fixed effects were used to compare annual rates of jobs and establishments recovery between ARRA-funded FQHC census tracts and a matched control group.ResultsOf 50,381 tracts, 2,223 contained ≥ 1 FQHC that received ARRA funding. A higher proportion of FQHC tracts had an extreme poverty designation (11.6% vs. 5.4%), high unemployment rate (45.4% vs. 30.3%), and > 50% minority racial/ethnic composition (48.1% vs. 36.3%). On average, jobs grew at an annual rate of 3.84 jobs per 1,000 population (95% CI: 3.62,4.06). In propensity-score weighted models, jobs in ARRA-funded tracts grew at a higher annual rate of 4.34 per 1,000 (95% CI: 2.56,6.12) relative to those with similar social vulnerability. We observed persistent decline in non-healthcare establishments (-1.35 per 10,000; 95% CI: -1.68,-1.02); but did not observe decline in healthcare establishments.ConclusionsDirect funding to HCs may be an effective strategy to support healthcare establishments and some jobs recovery in disadvantaged neighborhoods during recession, reinforcing the important multidimensional roles HCs play in these communities. However, HCs may benefit from additional investments that target upstream determinants of health to mitigate uneven recovery and neighborhood decline.
