Race, criminalization and urban mental health in the United States.

PURPOSE OF REVIEW: As efforts to increase policing and roll back criminal legal system reforms in major U.S. cities rise, the collateral consequences of increased criminalization remain critical to document. Although the criminalization of mental illness has been well studied in the U.S., the mental health effects of criminalization are comparatively under-researched. In addition, despite extreme racial disparities in U.S. policing, there is limited understanding of how criminalization may contribute to racial disparities in mental health. RECENT FINDINGS: Literature included in this review covers various types of criminalization, including direct and indirect impacts of incarceration, criminalization of immigration, first-hand and witnessed encounters with police, and the effects of widely publicized police brutality incidents. All forms of criminalization were shown to negatively impact mental health (depression, anxiety and suicidality), with evidence suggestive of disproportionate impact on Black people. SUMMARY: There is evidence of significant negative impact of criminalization on mental health; however, more robust research is needed to address the limitations of the current literature. These limitations include few analyses stratified by race, a lack of focus on nonincarceration forms of criminalization, few longitudinal studies limiting causal inference, highly selected samples limiting generalizability and few studies with validated mental health measures.

Racial/ethnic disparities in opioid overdose prevention: comparison of the naloxone care cascade in White, Latinx, and Black people who use opioids in New York City.

BACKGROUND: Drug overdose mortality is rising precipitously among Black people who use drugs. In NYC, the overdose mortality rate is now highest in Black (38.2 per 100,000) followed by the Latinx (33.6 per 100,000) and white (32.7 per 100,000) residents. Improved understanding of access to harm reduction including naloxone across racial/ethnic groups is warranted. METHODS: Using data from an ongoing study of people who use illicit opioids in NYC (N = 575), we quantified racial/ethnic differences in the naloxone care cascade. RESULTS: We observed gaps across the cascade overall in the cohort, including in naloxone training (66%), current possession (53%) daily access during using and non-using days (21%), 100% access during opioid use (20%), and complete protection (having naloxone and someone who could administer it present during 100% of opioid use events; 12%). Naloxone coverage was greater in white (training: 79%, possession: 62%, daily access: 33%, access during use: 27%, and complete protection: 13%, respectively) and Latinx (training: 67%, possession: 54%, daily access: 22%, access during use: 24%, and complete protection: 16%, respectively) versus Black (training: 59%, possession: 48%, daily access:13%, access during use: 12%, and complete protection: 8%, respectively) participants. Black participants, versus white participants, had disproportionately low odds of naloxone training (OR 0.40, 95% CI 0.22-0.72). Among participants aged 51 years or older, Black race (versus white, the referent) was strongly associated with lower levels of being trained in naloxone use (OR 0.20, 95% CI 0.07-0.63) and having 100% naloxone access during use (OR 0.34, 95% CI 0.13-0.91). Compared to white women, Black women had 0.27 times the odds of being trained in naloxone use (95% CI 0.10-0.72). CONCLUSIONS: There is insufficient protection by naloxone during opioid use, with disproportionately low access among Black people who use drugs, and a heightened disparity among older Black people and Black women.

Persistent Criminalization and Structural Racism in US Drug Policy: The Case of Overdose Good Samaritan Laws.

The US overdose crisis continues to worsen and is disproportionately harming Black and Hispanic/Latino people. Although the "War on Drugs" continues to shape drug policy-at the disproportionate expense of Black and Hispanic/Latino people-states have taken some steps to reduce War on Drugs-related harms and adopt a public health-centered approach. However, the rhetoric regarding these changes has, in many cases, outstripped reality. Using overdose Good Samaritan Laws (GSLs) as a case study, we argue that public health-oriented policy changes made in some states are undercut by the broader enduring environment of a structurally racist drug criminalization agenda that continues to permeate and constrict most attempts at change. Drawing from our collective experiences in public health research and practice, we describe 3 key barriers to GSL effectiveness: the narrow parameters within which they apply, the fact that they are subject to police discretion, and the passage of competing laws that further criminalize people who use illicit drugs. All reveal a persisting climate of drug criminalization that may reduce policy effectiveness and explain why current reforms may be destined for failure and further disadvantage Black and Hispanic/Latino people who use drugs.

Use of an Inverted Synthetic Control Method to Estimate Effects of Recent Drug Overdose Good Samaritan Laws, Overall and by Black/White Race/Ethnicity.

Overdose Good Samaritan laws (GSLs) aim to reduce mortality by providing limited legal protections when a bystander to a possible drug overdose summons help. Most research into the impact of these laws is dated or potentially confounded by coenacted naloxone access laws. Lack of awareness and trust in GSL protections, as well as fear of police involvement and legal repercussions, remain key deterrents to help-seeking. These barriers may be unequally distributed by race/ethnicity due to racist policing and drug policies, potentially producing racial/ethnic disparities in the effectiveness of GSLs for reducing overdose mortality. We used 2015-2019 vital statistics data to estimate the effect of recent GSLs on overdose mortality, overall (8 states) and by Black/White race/ethnicity (4 states). Given GSLs' near ubiquity, few unexposed states were available for comparison. Therefore, we generated an "inverted" synthetic control method (SCM) to compare overdose mortality in new-GSL states with that in states that had GSLs throughout the analytical period. The estimated relationships between GSLs and overdose mortality, both overall and stratified by Black/White race/ethnicity, were consistent with chance. An absence of effect could result from insufficient protection provided by the laws, insufficient awareness of them, and/or reticence to summon help not addressable by legal protections. The inverted SCM may be useful for evaluating other widespread policies.

Stress is a Latent Construct: Exploring the Differential Experience of Stress and Discrimination on Depressive Symptoms Among Black Older Adults.

Objectives: While evidence highlights the detrimental mental health consequences of chronic stress exposure, the impact of this stress exposure on older Black Americans' mental health varies by exposure to other types of stressors like discrimination as well as subjective evaluations of stress like chronic stress appraisal. Methods: Using data from the 2010/2012 Health and Retirement Study, we use latent profile analysis (LPA) to describe 2,415 Black older adults experience with chronic stress exposure, appraisal, and discrimination and examine which stress contexts are associated with depressive symptomology. Results: Analyses revealed five stress clusters-demonstrating the diversity in the stress experience for older Black adults. Black older adults with stress profiles that include lower stress appraisal report fewer depressive symptoms regardless of number of stress exposures. Discussion: LPA is as an alternative approach to examining the stress-mental health link that can define stress profiles by both exposure and appraisal-based measures.

Racial Disparities in Spatial and Temporal Youth Suicide Clusters.

OBJECTIVE: Deaths by suicide correlate both spatially and temporally, leading to suicide clusters. This study aimed to estimate racial patterns in suicide clusters since 2000. METHOD: Data from the US National Vital Statistics System included all International Classification of Diseases, Tenth Revision (ICD-10)-coded suicide cases from 2000-2019 among American Indian/Alaska Native (AI/AN), Asian/Pacific Islander (A/PI), Black, or White youth and young adults, aged 5-34 years. We estimated age, period, and cohort (APC) trends and identified spatiotemporal clusters using the SaTScan space-time statistic, which identified lower- and higher-than-expected suicide rates (cold and hot clusters) in a prespecified area (150 km) and time interval (15 months). We also calculated the average proportion of deaths by suicide contained in clusters, to quantify the relative importance of spatiotemporal patterning as a driver of overall suicide rates. RESULTS: From 2010-2019, suicide rates increased from between 37% among AI/AN (95% CI = 1.22, 1.55) to 81% among A/PI (95% CI = 1.65, 2.01) groups. Suicide clusters accounted for 0.8%-10.3% of all suicide deaths, across racial groups. Since 2000, the likelihood of detecting cluster increased over time, with considerable differences in the number of clusters in each racial group (4 among AI/AN to 72 among White youth). Among Black youth and young adults, 27 total clusters were identified. Hot clusters were concentrated in southeastern and mid-Atlantic counties. CONCLUSION: Suicide rates and clusters in youth and young adults have increased in the past 2 decades, requiring attention from policy makers, clinicians, and caretakers. Racially distinct patterns highlight opportunities to tailor individual- and population-level prevention efforts to prevent suicide deaths in emerging high-risk groups.

Evaluating hypothesized explanations for the Black-white depression paradox: A critical review of the extant evidence.

The Black-white Depression paradox, the lower prevalence of major depression among non-Hispanic Black (relative to non-Hispanic white) individuals despite their greater exposure to major life stressors, is a phenomenon that remains unexplained. Despite a decade plus of research, there is little clarity as to whether the paradoxical observations are an invalid finding, spuriously produced by selection bias, information bias, or confounding, or are a valid finding, representative of a true racial patterning of depression in the population. Though both artefactual and etiologic mechanisms have been tested, a lack of synthesis of the extant evidence has contributed towards an unclear picture of the validity of the paradox and produced challenges for researchers in determining which proposed mechanisms show promise, which have been debunked, and which require further study. The objective of this critical review is to assess the state of the literature regarding explanations for the Black-white depression paradox by examining some of the more prominent hypothesized explanatory mechanisms that have been proposed and assessing the state of the evidence in support of them. Included mechanisms were selected for their perceived dominance in the literature and the existence of at least one, direct empirical test using DSM major depression as the outcome. This review highlights the very limited evidence in support of any of the extant putative mechanisms, suggesting that investigators should redirect efforts towards identifying novel mechanisms, and/or empirically testing those which show promise but to date have been relatively understudied. We conclude with a discussion of the broader implications of the evidence for well-accepted social theories and raise questions regarding the use of DSM major depression to assess mental health burden in Black communities.

Explaining the Black-white depression paradox: Interrogating the Environmental Affordances Model.

The Environmental Affordances (EA) model posits that Black Americans' engagement with unhealthy behaviors (i.e. smoking, alcohol use, eating calorie-dense foods) to cope with stressor exposure may simultaneously account for their observed greater risk of chronic physical illness, and their observed equal or lesser prevalence of depression, relative to white Americans - the so-called "Black-white depression paradox." However, the specific mechanisms through which such effects might arise have been theorized and analyzed inconsistently across studies, raising concerns regarding the appropriateness of existing empirical tests of the model as well as the validity of the conclusions. We specify the two mechanisms most consistent with the EA model - 'Mediation-only' and 'Mediation and Modification' - and derive a priori predictions based on each. We systematically test these pathways using a subset of 559 participants of the Child Health and Development Study who were included in an adult follow-up study between 2010 and 2012 and self-identified as Black or white. Results failed to support either of the two mechanisms derived from the EA model, challenging the validity and utility of the model for explaining racial differences in depression; efforts to develop alternative hypotheses to explain the paradox are needed.

Age, period, and cohort effects on suicide death in the United States from 1999 to 2018: moderation by sex, race, and firearm involvement.

The role of sex, race, and suicide method on recent increases in suicide mortality in the United States remains unclear. Estimating the age, period, and cohort effects underlying suicide mortality trends can provide important insights for the causal hypothesis generating process. We generated updated age-period-cohort effect estimates of recent suicide mortality rates in the US, examining the putative roles of sex, race, and method for suicide, using data from all death certificates in the US between 1999 and 2018. After designating deaths as attributable to suicide according to ICD-10 underlying cause of death codes X60-X84, Y87.0, and U03, we (i) used hexagonal grids to describe rates of suicide by age, period, and cohort visually and (ii) modeled sex-, race-, and suicide method-specific age, period, and cohort effects. We found that, while suicide mortality increased in the US between 1999 and 2018 across age, sex, race, and suicide method, there was substantial heterogeneity in age and cohort effects by method, sex, and race, with a first peak of suicide risk in youth, a second peak in older ages-specific to male firearm suicide, and increased rates among younger cohorts of non-White individuals. Our findings should prompt discussion regarding age-specific clinical firearm safety interventions, drivers of minoritized populations' adverse early-life experiences, and racial differences in access to and quality of mental healthcare.

Racial differences in alcohol and tobacco use in adolescence and mid-adulthood in a community-based sample.

PURPOSE: Smoking and alcohol use have been posited as possible contributors to racial health disparities, despite higher smoking and alcohol use among non-Hispanic White youth and young adults compared to Blacks. To further investigate this claim, we aim to assess variation in alcohol and cigarette use across two distinct points of the life course. METHOD: Data are from a subset of 559 (279 male, 280 female) self-identified Black and White participants of the Child Health and Development study. Self-report alcohol and cigarette use were collected between age 15-17 and at mean age 50. Logistic regressions were estimated; supplementary analyses adjusted for maternal age, prenatal smoking, household income, childhood SES, and education. RESULTS: White participants were more likely to drink regularly (Odds ratio (OR) 2.2; 95%CI 1.2, 4.0) and be intoxicated (OR 2.0; 95%CI 1.2, 3.2) in adolescence compared with Blacks. In mid-adulthood, Whites remained more likely to currently drink (OR 2.3; 95%CI 1.6, 3.4) but among drinkers, less likely to binge drink (OR 0.4; 95%CI 0.2, 0.8). White participants were less likely to smoke in mid-adulthood (OR 0.4; 95%CI 0.3, 0.6), but among smokers, were more likely to smoke ≥ ½ a pack per day (OR 3.4; 95%CI 1.5, 7.8). CONCLUSIONS: Blacks were less likely to engage in drinking across the life course, but, among drinkers, more likely to binge drink in mid-adulthood. Blacks were more likely to smoke in mid-adulthood, but smoked infrequently compared with Whites. These patterns suggest that a reframing of disparities mechanisms to focus on broader structural and social factors may benefit progress in understanding and ameliorating inequities.

Sex differences in the association between perceived stress and adiposity in a nationally representative sample.

PURPOSE: Prior studies examining the association between perceived stress and adiposity have reported mixed findings, and sex differences have largely not been examined. METHODS: We examined the relationship between perceived stress and body mass index (BMI) and waist circumference in young adults in the National Longitudinal Study of Adolescent to Adult Health. Participants (mean age 29 years; N = 14,044) completed the short form of Cohen's Perceived Stress Scale during a home visit. Height, weight, and waist circumference were assessed during the same visit. BMI was calculated based on measured height and weight. RESULTS: In the sample, 52% were male and 65% were identified as white. In adjusted linear regression analyses, a sex by Perceived Stress Scale interaction was noted (P < .05) for both BMI and waist circumference. Perceived stress was statistically significantly associated with lower BMI (ß: -0.09; standard error [SE]: 0.05) and was associated with lower waist circumference, although not statistically significant (ß: -0.18; SE: 0.10) among men. No associations were noted among women. CONCLUSIONS: In this nationally representative sample of young adults, perceived stress was associated with lower levels of adiposity among men. Noted differences could be attributed to different behavioral and coping strategies in response to stress between men and women as well as biological mechanisms which should be explored further.

Sustained activation of GABAA receptors in the suprachiasmatic nucleus mediates light-induced phase delays of the circadian clock: a novel function of ionotropic receptors.

The suprachiasmatic nucleus (SCN) contains a circadian clock that generates endogenous rhythmicity and entrains that rhythmicity with the day-night cycle. The neurochemical events that transduce photic input within the SCN and mediate entrainment by resetting the molecular clock have yet to be defined. Because GABA is contained in nearly all SCN neurons we tested the hypothesis that GABA serves as this signal in studies employing Syrian hamsters (Mesocricetus auratus). Activation of GABAA receptors was found to be necessary and sufficient for light to induce phase delays of the clock. Remarkably, the sustained activation of GABAA receptors for more than three consecutive hours was necessary to phase-delay the clock. The duration of GABAA receptor activation required to induce phase delays would not have been predicted by either the prevalent theory of circadian entrainment or by expectations regarding the duration of ionotropic receptor activation necessary to produce functional responses. Taken together, these data identify a novel neurochemical mechanism essential for phase-delaying the 'master' circadian clock within the SCN as well as identifying an unprecedented action of an amino acid neurotransmitter involving the sustained activation of ionotropic receptors.
