Ethnoracial Risk Variation Across the Psychosis Continuum in the US: A Systematic Review and Meta-Analysis. JAMA Psychiatry 2024; 81:447-455. [PMID: 38381422 PMCID: PMC10882506 DOI: 10.1001/jamapsychiatry.2023.5497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 11/26/2023] [Indexed: 02/22/2024]
Abstract
Importance Studies suggest a higher risk of schizophrenia diagnoses in Black vs White Americans, yet a systematic investigation of disparities that include other ethnoracial groups and multiple outcomes on the psychosis continuum is lacking. Objective To identify ethnoracial risk variation in the US across 3 psychosis continuum outcomes (ie, schizophrenia and other psychotic disorders, clinical high risk for psychosis [CHR-P], and psychotic symptoms [PSs] and psychotic experiences [PEs]). Data Sources PubMed, PsycINFO and Embase were searched up to December 2022. Study Selection Observational studies on ethnoracial differences in risk of 3 psychosis outcomes. Data Extraction and Synthesis Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. Using a random-effects model, estimates for ethnoracial differences in schizophrenia and PSs/PEs were pooled and moderation by sampling and setting was determined, along with the assessment of heterogeneity and risk of bias. Main Outcomes and Measures Risk of schizophrenia and other psychotic disorder, CHR-P, and conversion to psychosis among CHR-P and PSs/PEs. Results Of 64 studies in the systematic review, 47 were included in the meta-analysis comprising 54 929 people with schizophrenia and 223 097 with data on PSs/PEs. Compared with White individuals, Black individuals had increased risk of schizophrenia (pooled odds ratio [OR], 2.07; 95% CI, 1.64-2.61) and PSs/PEs (pooled standardized mean difference [SMD], 0.10; 95% CI, 0.03-0.16), Latinx individuals had higher risk of PSs/PEs (pooled SMD, 0.15; 95% CI, 0.08-0.22), and individuals classified as other ethnoracial group were at significantly higher risk of schizophrenia than White individuals (pooled OR, 1.81; 95% CI, 1.31-2.50). The results regarding CHR-P studies were mixed and inconsistent. Sensitivity analyses showed elevated odds of schizophrenia in Asian individuals in inpatient settings (pooled OR, 1.84; 95% CI, 1.19-2.84) and increased risk of PEs among Asian compared with White individuals, specifically in college samples (pooled SMD, 0.16; 95% CI, 0.02-0.29). Heterogeneity across studies was high, and there was substantial risk of bias in most studies. Conclusions and Relevance Findings of this systematic review and meta-analysis revealed widespread ethnoracial risk variation across multiple psychosis outcomes. In addition to diagnostic, measurement, and hospital bias, systemic influences such as structural racism should be considered as drivers of ethnoracial disparities in outcomes across the psychosis continuum in the US.

Abstract
Background Tuberculosis may play a role in the aetiology of psychosis. However, little is known about the association between tuberculosis and psychotic experiences (PEs) or the mediating factors of this association. Methods We analysed cross-sectional data from 48 low- and middle-income countries of the World Health Survey (WHS). Tuberculosis assessment was based on past 12-month symptoms of active tuberculosis. We assessed four types of past 12-month PEs with the Composite International Diagnostic Interview. We performed multivariable multinomial logistic regression and mediation analysis. Results We analysed data on 224 842 individuals aged ≥18 years (mean age = 38.3 years, standard deviation = 16.0; 50.7% women). Tuberculosis was associated with 1.84 (95% confidence interval (CI) = 1.41-2.40), 2.18 (95%CI = 1.58-3.03), and 3.79 (95%CI = 2.88-4.98) times higher odds for 1, 2, and ≥3 PEs, respectively. The mediation analysis showed that the association between tuberculosis and at least one PE is mainly explained by anxiety (31.5%), sleep/energy (27.8%), and pain/discomfort (23.5%). Conclusions Tuberculosis was associated with increased odds of PEs. Factors such as affect, sleep, and pain should be considered in tuberculosis patients to target those who might be particularly vulnerable to PEs, and consequently, to psychotic disorders and other adverse effects of PE.

The separate and joint effects of recent interpersonal abuse and cannabis use on psychotic experiences: findings from students in higher education in the United States. Soc Psychiatry Psychiatr Epidemiol 2024; 59:77-85.

Abstract
BACKGROUND Various forms of interpersonal abuse (e.g., physical, emotional, sexual) and cannabis use across the lifespan have both been known to increase odds of psychotic experiences; however, there have been few studies examining their separate and joint effects in the United States. METHODS We analyzed data from the Healthy Minds Study (2020-2021) and used multivariable logistic regression and interaction contrast ratios to assess separate and joint effects of interpersonal abuse (past 12 months) and cannabis use (past 30 days) on psychotic experiences (past 12 months). RESULTS Students who only used cannabis had significantly greater odds of psychotic experiences (aOR: 1.70; 95% CI 1.58-1.82), as well as those who only experienced interpersonal abuse (aOR: 2.40; 95% CI 2.25-2.56). However, those who reported both cannabis use and interpersonal abuse had the greatest odds, exceeding the sum of these individual effects (the combined effect aOR: 3.46; 95% CI 3.19-3.76). CONCLUSIONS Recent interpersonal abuse and recent cannabis use both separately and jointly increase odds of having recent psychotic experiences. Future research should continue to examine the potential interactive and additive impact of multiple known exposures to better inform primary and secondary prevention efforts.

Exploring the relation between psychosis-like experiences and suicidal ideation, plans, and attempts among college students in the United States. Early Interv Psychiatry 2023; 17:272-280. [PMID: 35712796 DOI: 10.1111/eip.13325] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Revised: 03/27/2022] [Accepted: 05/29/2022] [Indexed: 11/25/2022]
Abstract
AIM The suicide rate among college students is particularly high, with evidence that psychosis-like experiences (PLEs) put these individuals at greater risk. The current study explored whether there are differential relations between four subtypes of PLEs and three suicide outcomes. METHODS We analysed a large sample of college students from the Fall semester cohort of the 2020 Healthy Minds Study (HMS) (weighted N = 36727). PLEs and suicide outcomes were assessed using binary variables from the World Health Organization Composite International Diagnostic Interview. RESULTS Findings revealed that reporting any of the subtypes of PLEs was associated with greater odds of suicidal ideation (SI), a suicide plan (SP) and a suicide attempt (SA) (signficant a ORs ranging from 1.30 to 3.30). For college students who endorsed SI or a SP in the past year, experiencing delusional mood (aOR [95% CI] = 1.30 [1.02-1.65]), suspiciousness (aOR [95% CI] = 1.31 [1.00-1.71]) and hallucinatory experiences (aOR [95% CI] = 2.76 [2.05-3.71]) in their lifetime increased their odds of reporting a SA in the past year. There was also evidence of a dose-dependent relation between the number of PLEs endorsed and all three suicide outcomes. CONCLUSIONS Certain subtypes of PLEs including delusional mood, suspiciousness and hallucinatory experiences may contribute to an elevated risk of suicide outcomes in college students. Moreover, the odds of reporting suicide outcomes were greater for individuals who endorsed a greater number of PLEs. It may be helpful to assess for indicated subtypes when determining suicide risk among college students and to be particularly mindful of those who report three or more PLEs.

Abstract
BACKGROUND Religiousness and psychotic experiences have been related, though findings have been mixed, with little attention paid to specific religious affiliations and religious importance. METHODS We analyzed data from the Healthy Minds Study (2020-2021), which was an online survey administered at 140 college campuses across the United States. We used multivariable logistic regression to examine the associations between religiousness (affiliation and importance) and 12-month psychotic experiences, adjusting for age, gender, and race/ethnicity. RESULTS Only Christian religious affiliation was associated with lower odds of psychotic experiences (aOR: 0.79; 95% CI: 0.75, 0.84), while Non-Christian religious affiliation (aOR: 1.34; 95% CI: 1.19, 1.50) and Multiple religious affiliation s were associated with greater odds (aOR: 1.28; 95% CI: 1.15, 1.42). Overall, increased religious importance was associated with lower odds of psychotic experiences (aOR: 0.96; 95% CI: 0.94-0.99). After stratifying by affiliation, religious importance was only associated with lower odds of psychotic experiences among people who identified as Other Christian, Mormon, and Other World Religion. Religious importance was associated with greater odds of psychotic experiences among Atheists, Agnostics, Buddhists, Nothing in Particular, and Multiple Religions. CONCLUSION Religious affiliation and importance had varying associations with psychotic experiences, depending on type of religious affiliation. More research is needed to explore the modifying effects of religiousness. Responsiveness to religious beliefs and practices may be critical when assessing risk for psychosis.

Abstract
AIM Socioeconomic status (SES) is linked to psychosis, and much can be learned by examining how various indicators of SES-specifically economic strain and intergenerational transfer of resources-are related to sub-threshold psychotic experiences among college students. METHODS Using data from the Healthy Minds Survey (September 2020-December 2020), we used multivariable logistic regression models to examine the associations between five SES indicators and 12-month psychotic experiences, adjusting for age, gender and race/ethnicity. We also examined the count of predictors and psychotic experiences. RESULTS Each indicator of economic strain was associated with greater odds of psychotic experiences. In particular, increasing levels of financial stress (current, childhood and pandemic-related) were associated with greater odds of psychotic experiences in a dose-response fashion. Food insecurity was associated with double the odds of psychotic experiences. In terms of intergenerational transfer of resources, having either one or no parents who attended college was associated with significantly greater odds of having psychotic experiences, when compared with having both parents who attended college. Examining all predictors in the same model, only childhood and current financial stress and food insecurity were significantly associated with psychotic experiences. The count of predictors was significantly associated with greater odds of having psychotic experiences in a dose-dependent fashion. CONCLUSIONS Among college students, economic strain and intergenerational transfer of resources were associated with recent psychotic experiences, highlighting the importance of economic interventions targeting young adults to influence risk for psychosis.

Abstract
Background Clinical reports from across the world have documented psychosis in the context of COVID-19 infection; however, there has yet to be a large-scale epidemiological study to confirm this association. Methods We analyzed data from the Healthy Minds Study (N = 15,935; conducted between September and December 2020), which was administered online to students attending one of 28 colleges in the United States. Using multivariable logistic regression, we examined the associations between COVID-19 infection/severity and psychotic experiences over the past 12 months, adjusting for age, gender, race/ethnicity, and international student status as well as anxiety and depression. Results More than one fifth of the analytic sample reported COVID-19 infection, and about one in six students with COVID-19 infection reported psychotic experiences over the past 12 months. In weighted multivariable logistic regression models, COVID-19 infection was associated with significantly greater odds of having psychotic experiences (adjusted odds ratio 1.36, 95% CI 1.19–1.48). Compared with being asymptomatic, having moderate (adjusted odds ratio 1.85, 95% CI 1.03–3.31) or severe (adjusted odds ratio 1.76, 95% CI 1.11–2.77) symptoms was associated with significantly greater odds of having psychotic experiences. These associations became statistically nonsignificant when adjusting for depression and anxiety. Hospitalization was not significantly associated with psychotic experiences among students with COVID-19 infection. Conclusions Psychotic experiences are associated with COVID-19 infections, though much of the association is attenuated when accounting for anxiety and depression. Findings based on this sample of college students should be replicated outside of the college context to determine whether psychosis is a neuropsychiatric symptom during and after COVID-19 infection.
