A Systematic Review of the State of Neurosurgical Disparities Research: Past, Present, and Future.

BACKGROUND: The social determinants of health, which influence healthcare access, patient outcomes, and population-level burden of disease, contribute to health disparities experienced by marginalized patient populations. In the present study, we sought to evaluate the landscape of health disparities research within neurosurgery. METHODS: Embase, Ovid-MEDLINE, Scopus, Web of Science, Cochrane Library, and ProQuest Dissertations databases were queried for original research on health disparities regarding access to, outcomes of, and/or postoperative management after neurosurgical procedures in the United States. RESULTS: Of 883 studies screened, 196 were included, of which 144 had a neurosurgery-affiliated author. We found a significant increase in the number of neurosurgical disparities reports beginning in 2010, with only 10 studies reported before 2010. Of the included studies, 3.1% used prospective methods and 63.8% used data from national registries. The disparities analyzed were racial/ethnic (79.6%), economic/socioeconomic (53.6%), gender (18.9%), and disabled populations (0.5%), with 40.1% analyzing multiple or intersecting disparities. Of the included reports, 96.9% were in phase 1 (detecting phase of disparities research), with a few studies in phase 2 (understanding phase), and none in phase 3 (reducing phase). The spine was the most prevalent subspecialty evaluated (34.2%), followed by neuro-oncology (19.9%), cerebrovascular (16.3%), pediatrics (10.7%), functional (9.2%), general neurosurgery (5.1%), and trauma (4.1%). Senior authors with a neurosurgical affiliation accounted for 79.2% of the reports, 93% of whom were academically affiliated. CONCLUSIONS: Although a recent increase has occurred in neurosurgical disparities research within the past decade, most studies were limited to the detection of disparities without understanding or evaluating any interventions for a reduction in disparities. Future research in neurosurgical disparities should incorporate the latter 2 factors to reduce disparities and improve outcomes for all patients.

Mass Probation: Effects of Sentencing Severity on Mental Health for Black and White Individuals.

BACKGROUND: Incarceration is associated with negative impacts on mental health. Probation, a form of community supervision, has been lauded as an alternative. However, the effect of probation versus incarceration on mental health is unclear. Our objective was to estimate the impact on mental health of reducing sentencing severity at individuals' first adult criminal-legal encounter. METHODS: We used the US National Longitudinal Survey on Youth 1997, a nationally representative dataset of youth followed into their mid-thirties. Restricting to those with an adult encounter (arrest, charge alone or no sentence, probation, incarceration), we used parametric g-computation to estimate the difference in mental health at age 30 (Mental Health Inventory-5) if (1) everyone who received incarceration for their first encounter had received probation and (2) everyone who received probation had received no sentence. RESULTS: Among 1835 individuals with adult encounters, 19% were non-Hispanic Black and 65% were non-Hispanic White. Median age at first encounter was 20. Under hypothetical interventions to reduce sentencing, we did not see better mental health overall (Intervention 1, incarceration to probation: RD = -0.01; CI = -0.02, 0.01; Intervention 2, probation to no sentence: RD = 0.00; CI = -0.01, 0.01) or when stratified by race. CONCLUSION: Among those with criminal-legal encounters, hypothetical interventions to reduce sentencing, including incremental sentencing reductions, were not associated with improved mental health. Future work should consider the effects of preventing individuals' first criminal-legal encounter.

Medical student specialty decision-making and perceptions of neurosurgery. Part 2: Role of race/ethnicity.

OBJECTIVE: Although individuals underrepresented in medicine (URM) make up 33% of the United States population, only 12.6% of medical school graduates identify as URM; the same percentage of URM students comprises neurosurgery residency applicants. More information is needed to understand how URM students are making specialty decisions and their perceptions of neurosurgery. The authors aimed to evaluate the differences between URM and non-URM medical students and residents in terms of the factors that contribute to specialty decision-making and perceptions of neurosurgery. METHODS: A survey was administered to all medical students and resident physicians at a single Midwestern institution to assess factors influencing medical student specialty decision-making and perceptions of neurosurgery. Likert scale responses converted to numerical values on a 5-point scale (strongly agree was the high score of 5) were analyzed with the Mann-Whitney U-test. The chi-square test was performed on the binary responses to examine associations between categorical variables. Semistructured interviews were conducted and analyzed using the grounded theory method. RESULTS: Of 272 respondents, 49.2% were medical students, 51.8% were residents, and 11.0% identified as URM. URM medical students considered research opportunities more than non-URM medical students in specialty decision-making (p = 0.023). When specialty decision-making factors were assessed, URM residents less strongly considered the technical skill required (p = 0.023), their perceived fit in the field (p < 0.001), and seeing people like them in the field (p = 0.010) than their non-URM counterparts when making specialty decisions. Within both medical student and resident respondent cohorts, the authors found no significant differences between URM and non-URM respondents in terms of their specialty decision-making being affected by medical school experiences such as shadowing, elective rotations, family exposure, or having a mentor in the field. URM residents were more concerned about the opportunity to work on health equity issues in neurosurgery than non-URM residents (p = 0.005). The predominant theme that emerged from interviews was the need for more intentional efforts to recruit and retain URM individuals in medicine and specifically neurosurgery. CONCLUSIONS: URM students may make specialty decisions differently than non-URM students. URM students were more hesitant toward neurosurgery due to their perceived lack of opportunity for health equity work in neurosurgery. These findings further inform optimization of both new and existing initiatives to improve URM student recruitment and retention in neurosurgery.

Policing and Population Health: Past, Present, and Future.

Policy Points A growing body of research suggests that policing, as a form of state-sanctioned racial violence, operates as a social determinant of population health and racial or ethnic health disparities. A lack of compulsory, comprehensive data on interactions with police has greatly limited our ability to calculate the true prevalence and nature of police violence. While innovative unofficial data sources have been able to fill these data gaps, compulsory and comprehensive data reporting on interactions with police, as well as considerable investments in research on policing and health, are required to further our understanding of this public health issue.

State-Level Variation in the Cumulative Prevalence of Child Welfare System Contact, 2015-2019.

Background: Prior estimates of the cumulative risks of child welfare system contact illustrate the prominence of this system in the lives of children in the United States (U.S.). However, these estimates report national data on a system administered at the state and local levels and are unable to detail potential simultaneous geographic and racial/ethnic variation in the prevalence of these events. Methods: Using 2015-2019 data from the National Child Abuse and Neglect Data System and Adoption and Foster Care Analysis and Reporting System, we use synthetic cohort life tables to estimate cumulative state- and race/ethnicity-specific risks by age 18 of experiencing: (1) a child protective services investigation, (2) confirmed maltreatment, (3) foster care placement, and (4) termination of parental rights for children in the U.S. Results: In the U.S., state-level investigation risks ranged from 14% to 63%, confirmed maltreatment risks from 3% to 27%, foster care placement risks from 2% to 18%, and risks of parental rights termination from 0% to 8%. Racial/ethnic disparities in these risks varied greatly across states, with larger disparities at higher levels of involvement. Whereas Black children had higher risks of all events than white children in nearly all states, Asian children had consistently lower risks. Finally, ratios comparing risks of child welfare events show these prevalences did not move in parallel, across states or racial/ethnic groups. Contribution: This study provides new estimates of spatial and racial/ethnic variation in children's lifetime risks of maltreatment investigation, confirmed maltreatment, foster care placement, and termination of parental rights in the U.S., as well as relative risks of these events.

Racial/ethnic differences in the relationship between wealth and health across young adulthood.

•Wealth attenuated racial differences in self-rated health during young adulthood.•Wealth had consistent incremental effect on health among White & Hispanic Americans.•For Black Americans, wealth was protective of health in the highest wealth quartile.•Individual wealth, not parental wealth was associated with health among Hispanics.

Racial and Ethnic Disparities in Housing Instability During the COVID-19 Pandemic: the Role of Assets and Income Shocks.

Stable and adequate housing is critical to sound public health responses in the midst of a pandemic. This study explores the disproportionate impact of the COVID-19 pandemic on housing-related hardships across racial/ethnic groups in the USA as well as the extent to which these disparities are mediated by households' broader economic circumstances, which we operationalized in terms of prepandemic liquid assets and pandemic-related income losses. Using a longitudinal national survey with more than 23,000 responses, we found that Black and Hispanic respondents were more vulnerable to housing-related hardships during the pandemic than white respondents. These impacts were particularly pronounced in low- and moderate-income households. We found that liquid assets acted as a strong mediator of the housing hardship disparities between white and Black/Hispanic households. Our findings imply that housing became less stable for minority groups as a result of the pandemic, particularly those households with limited liquid assets. Such housing-related disparities demonstrate the need for policies and practices that target support to economically marginalized groups and families of color in particular.

Vicarious Exposure to the Criminal Legal System Among Parents and Siblings.

Objective: This study documents life course patterns of vicarious exposure to the criminal legal system among parents and siblings in the United States. Background: The criminal legal system shapes family outcomes in important ways. Still, life course patterns of vicarious exposure to the system-especially to lower-level contacts-among parents and siblings are not well documented. Method: Using longitudinal data from the Panel Study of Income Dynamics, Kaplan-Meier survival curves, and Cox regression models, we estimate cumulative risks of vicarious exposure to arrest, probation, and incarceration among parents (n=3,885 parents; 185,444 person-years) and siblings (n=1,875; 44,766 person-years) and examine disparities by race-ethnicity, gender, and education, and at their intersections. Results: Vicarious exposure to the system is common-but highly unequal-among parents and siblings. Racially minoritized parents and siblings had greater levels and earlier risks of exposure. For example, by age 50, an estimated one in five Black parents experienced having a child incarcerated, a risk about twice as high as White and 50% higher than Latinx parents. By age 26, an estimated six in 10 Black young people with brothers experienced having a brother arrested; more than four in 10 experienced a brother on probation; and more than three in 10 experienced brother incarceration. For many estimates, racialized inequities in risks of vicarious system exposure widened at higher levels of education. Conclusion: These findings provide essential context for understanding the role of the criminal legal system in maintaining and exacerbating family inequality.

Highly public anti-Black violence and preterm birth odds for Black and White mothers.

Highly public anti-Black violence may increase preterm birth in the general population of pregnant women via stress-mediated paths, particularly Black women exposed in early gestation. To examine spillover from racial violence in the US, we included a total of 49 high publicity incidents of the following types: police lethal force toward Black persons, legal decisions not to indict/convict officers involved, and hate crime murders of Black victims. National search interest in these incidents was measured via Google Trends to proxy for public awareness of racial violence. Timing of racial violence was coded in relation to a three-month preconception period and subsequent pregnancy trimesters, with the primary hypothesis being that first trimester exposure is associated with higher preterm birth odds. The national sample included 1.6 million singleton live births to US-born Black mothers and 6.6 million births to US-born White mothers from 2014 to 2017. Using a preregistered analysis plan, findings show that Black mothers had 5% higher preterm birth odds when exposed to any high publicity racial incidents relative to none in their first trimester, and 2-3% higher preterm birth odds with each log10 increase in national interest. However, post hoc sensitivity tests that included month fixed effects attenuated these associations to null. For White mothers, associations were smaller but of a similar pattern, and were attenuated when including month fixed effects. Highly public anti-Black violence may act as a national stressor, yet whether racial violence is associated with reproductive outcomes in the population is unknown and merits further research.

Early life patterns of criminal legal system involvement: Inequalities by race/ethnicity, gender, and parental education.

BACKGROUND: Contacts with the criminal legal system have consequences for a host of outcomes. Still, early life age patterns of system involvement remain to be better understood. OBJECTIVE: We estimate cumulative risks of arrest, probation, and incarceration from childhood through early adulthood and assess disparities by race/ethnicity, gender, and parental education. METHODS: Data come from the Transition to Adulthood Supplement of the Panel Study of Income Dynamics (n = 2,736). We use Kaplan-Meier curves and Cox regression models to estimate cumulative risks of arrest, probation, and incarceration across the early life course and document disparities by race/ethnicity, gender, and parental education, as well as at their intersections. RESULTS: Criminal legal system involvement is common among recent cohorts, but Black and Latinx boys and young men face especially high risks. Among Black men whose highest-educated parent completed high school or less, an estimated six in ten had been arrested, four in ten had experienced probation, and four in ten had been incarcerated by age 26. Among Latinx men whose highest-educated parent completed high school or less, an estimated four in ten had been arrested and one in four had been incarcerated by age 26. Black women also experienced high risks, with an estimated one in four arrested by age 26. CONTRIBUTION: We document early life patterns of criminal legal system involvement among young people who came of age during the expansion of proactive policing and mass incarceration in the United States, providing important context for understanding the role of the system in generating and exacerbating life course inequalities.

Theory and empiricism: A comment on "Interrogating the environmental affordances model" by Pamplin and colleagues.

We strongly support efforts to generate, rigorously test, and falsify hypotheses derived from the Environmental Affordances (EA) Model of Health Disparities, as originated by the late Dr. James S. Jackson (1940-2020). Such efforts are critical to establishing robust, theoretically grounded scientific frameworks that explain the fundamental causes of racial disparities in health and wellbeing. Pamplin et al. (2021) fundamentally misrepresents the EA Model as a framework that (falsely) reifies the role of race as a determinant of health behaviors and health outcomes. Further, both their study design and analytic approach are inappropriate for testing predictions of this framework. We address these issues with the goal of recentering the scholarly conversation about how stress contributes to health, and disparities in health, over the life course.

Exposure to Family Member Incarceration and Adult Well-being in the United States.

Importance: More than half of the adult population in the United States has ever had a family member incarcerated, an experience more common among Black individuals. The impacts of family incarceration on well-being are not fully understood. Objective: To assess the associations of incarceration of a family member with perceived well-being and differences in projected life expectancy. Design, Setting, and Participants: This nationally representative cross-sectional study used data from the 2018 Family History of Incarceration Survey to examine how experiences of family member incarceration were associated with a holistic measure of well-being, including physical, mental, social, financial, and spiritual domains. Well-being was used to estimate change in life expectancy and was compared across varying levels of exposure to immediate and extended family member incarceration using logistic regression models to adjust for individual and household characteristics. Data were analyzed from October 2019 to April 2020. Exposures: Respondents' history of family member incarceration, including immediate and extended family members. Main Outcomes and Measures: The main outcome was self-reported life-evaluation, a measure of overall well-being from the 100 Million Healthier Lives Adult Well-being Assessment. Respondents were considered thriving with a current life satisfaction score of 7 or greater and a future life optimism score of 8 or greater, each on a scale of 0 to 10. Other outcomes included physical health, mental health, social support, financial well-being, and spiritual well-being, each measured with separate scales. Additionally, life expectancy projections were estimated using population-level correlations with the Life Evaluation Index. All percentages were weighted to more closely represent the US population. Results: Of 2815 individuals included in analysis, 1472 (51.7%) were women, 1765 (62.8%) were non-Hispanic White, and 868 (31.5%) were aged 35 to 54 years. A total of 1806 respondents (45.0%) reported having an immediate family member who was incarcerated. Compared with respondents with no family incarceration, any family member incarceration was associated with lower well-being overall (thriving: 69.5% [95% CI, 65.0%-75.0%] vs 56.9% [95% CI, 53.9%-59.9%]) and in every individual domain (eg, physical thriving: 51.1% [95% CI, 46.2-56.0] vs 35.5% [95% CI, 32.6%-38.3%]) and with a mean (SE) estimated 2.6 (0.03) years shorter life expectancy. Among those with any family incarceration, Black respondents had a mean (SE) estimated 0.46 (0.04) fewer years of life expectancy compared with White respondents. Conclusions and Relevance: These findings suggest that family member health and well-being may be an important avenue through which incarceration is associated with racial disparities in health and mortality. Decarceration efforts may improve population-level well-being and life expectancy by minimizing detrimental outcomes associated with incarceration among nonincarcerated family members.

Women's Health in the Era of Mass Incarceration.

Dramatic increases in criminal justice contact in the United States have rendered prison and jail incarceration common for US men and their loved ones, with possible implications for women's health. This review provides the most expansive critical discussion of research on family member incarceration and women's health in five stages. First, we provide new estimates showing how common family member incarceration is for US women by race/ethnicity and level of education. Second, we discuss the precursors to family member incarceration. Third, we discuss mechanisms through which family member incarceration may have no effect on women's health, a positive effect on women's health, and a negative effect on women's health. Fourth, we review existing research on how family member incarceration is associated with women's health. Fifth, we continue our discussion of the limitations of existing research and provide some recommendations for future research.

Barring progress: The influence of paternal incarceration on families' neighborhood attainment.

A growing body of literature has recognized that incarceration has implications beyond the offender, with detrimental effects reverberating onto families. In this study, we use the Fragile Families and Child Wellbeing Study (N = 3288) to investigate the relationships between paternal incarceration and the neighborhood outcomes of the children of incarcerated fathers and their mothers. Specifically, we examine whether children whose fathers are currently and/or have recently been incarcerated experience more residential instability, live in more socioeconomically disadvantaged neighborhoods, and/or live in less socially cohesive neighborhoods. We find that paternal incarceration is associated with moving more frequently, greater socioeconomic neighborhood disadvantage, and lower social cohesion for the children of incarcerated fathers and their mothers, though some of these relationships depend on the timing of paternal incarceration. Our findings have important implications for understanding the societal costs of incarceration, the nature of neighborhood attainment and inequality for families facing paternal incarceration, and the processes through which some families are sorted into their neighborhood contexts.

Risk of Police-Involved Death by Race/Ethnicity and Place, United States, 2012-2018.

OBJECTIVES: To estimate the risk of mortality from police homicide by race/ethnicity and place in the United States. METHODS: We used novel data on police-involved fatalities and Bayesian models to estimate mortality risk for Black, Latino, and White men for all US counties by Census division and metropolitan area type. RESULTS: Police kill, on average, 2.8 men per day. Police were responsible for about 8% of all homicides with adult male victims between 2012 and 2018. Black men's mortality risk is between 1.9 and 2.4 deaths per 100 000 per year, Latino risk is between 0.8 and 1.2, and White risk is between 0.6 and 0.7. CONCLUSIONS: Police homicide risk is higher than suggested by official data. Black and Latino men are at higher risk for death than are White men, and these disparities vary markedly across place. Public Health Implications. Homicide reduction efforts should consider interventions to reduce the use of lethal force by police. Efforts to address unequal police violence should target places with high mortality risk.

The weight of racism: Vigilance and racial inequalities in weight-related measures.

In the United States, racial/ethnic inequalities in obesity are well-documented, particularly among women. Using the Chicago Community Adult Health Study, a probability-based sample in 2001-2003 (N = 3105), we examined the roles of discrimination and vigilance in racial inequalities in two weight-related measures, body mass index (BMI) and waist circumference (WC), viewed through a cultural racism lens. Cultural racism creates a social environment in which Black Americans bear the stigma burden of their racial group while White Americans are allowed to view themselves as individuals. We propose that in this context, interpersonal discrimination holds a different meaning for Blacks and Whites, while vigilance captures the coping style for Blacks who carry the stigma burden of the racial group. By placing discrimination and vigilance within the context of cultural racism, we operationalize existing survey measures and utilize statistical models to clarify the ambiguous associations between discrimination and weight-related inequalities in the extant literature. Multivariate models were estimated for BMI and WC separately and were stratified by gender. Black women had higher mean BMI and WC than any other group, as well as highest levels of vigilance. White women did not show an association between vigilance and WC but did show a strong positive association between discrimination and WC. Conversely, Black women displayed an association between vigilance and WC, but not between discrimination and WC. These results demonstrate that vigilance and discrimination may hold different meanings for obesity by ethnoracial group that are concealed when all women are examined together and viewed without considering a cultural racism lens.

Stress, self-regulation, and context: Evidence from the Health and Retirement Survey.

Health-related behaviors, such as smoking, alcohol use, exercise, and diet, are major determinants of physical health and health disparities. However, a growing body of experimental research in humans and animals also suggests these behaviors can impact the ways our bodies respond to stress, such that they modulate (that is, serve as a means to self-regulate or cope with) the deleterious impact of stressful experiences on mental health. A handful of epidemiologic studies have investigated the intersection between stress and health behaviors on health disparities (both mental and physical), with mixed results. In this study we use a novel instrument designed to explicitly measure the self-regulatory motivations and perceived effectiveness of eight health-related self-regulatory behaviors (smoking, alcohol, drug use, overeating, prayer, exercise, social support, talking with a councilor) in a subset of the Health and Retirement Study (N=1,354, Mean age=67, 54% female). We find that these behaviors are commonly endorsed as self-regulatory stress-coping strategies, with prayer, social support, exercise, and overeating used most frequently. The likelihood of using particular behaviors as self-regulatory strategies varied significantly by sex, but not by race/ethnicity, education, or wealth. We also find that greater stress exposure is associated with higher likelihood of using these behaviors to self-regulate feelings of emotional distress, particularly health-harming behaviors like smoking, alcohol, and overeating. These findings provide an important link between sociological and psychological theoretical models on stress and empirical epidemiological research on social determinants of health and health disparities.

Living under surveillance: Gender, psychological distress, and stop-question-and-frisk policing in New York City.

A growing body of research highlights the collateral consequences of mass incarceration, including stop-and-frisk policing tactics. Living in a neighborhood with aggressive policing may affect one's mental health, especially for men who are the primary targets of police stops. We examine whether there is an association between psychological distress and neighborhood-level aggressive policing (i.e., frisking and use of force by police) and whether that association varies by gender. The 2009-2011 New York City (NYC) Stop, Question, and Frisk Database is aggregated to the neighborhood-level (N = 34) and merged with individual data from the 2012 NYC Community Health Survey (N = 8066) via the United Hospital Fund neighborhood of respondents' residence. Weighted multilevel generalized linear models are used to assess main and gendered associations of neighborhood exposures to aggressive police stops on psychological distress (Kessler-6 items). While the neighborhood stop rate exhibits inconsistent associations with psychological distress, neighborhood-level frisk and use of force proportions are linked to higher levels of non-specific psychological distress among men, but not women. Specifically, men exhibit more non-specific psychological distress and more severe feelings of nervousness, effort, and worthlessness in aggressively surveilled neighborhoods than do women. Male residents are affected by the escalation of stop-and-frisk policing in a neighborhood. Living in a context of aggressive policing is an important risk factor for men's mental health.
