Ethnic group preferences and the evaluation of ethnic identity among adolescents in The Netherlands.

The relationship between the evaluation of ethnic identity and ethnic group preferences among Dutch and that among ethnic minority adolescents was examined. It was predicted that a more positive attitude toward one's own ethnic identity would be associated with a higher level of ingroup preference. This prediction was confirmed, and this led to the question of how inter-ethnic relations and a positive ethnic identity could be stimulated simultaneously. Not only the ingroup aspect of ethnic group relations was studied but also the outgroup aspect. As members of the high-status group, the Dutch subjects showed a higher level of ingroup preference, compared with ethnic minorities. Also, own-group identification and own-group-oriented patterns of preferences among the Dutch subjects were found to be accompanied by the rejection of minority groups. No such tendency was found among adolescents from ethnic minorities.

Salience of ethnicity in the spontaneous self-concept as a function of one's ethnic distinctiveness in the social environment.

How likely people are to think of themselves in terms of a given personal characteristic is predicted from the distinctiveness postulate that the person, when confronted by a complex stimulus (such as the self), selectively notices and encodes the stimulus in terms of what is most peculiar about it, since these peculiar characteristics are the most informative in distinguishing it from other stimuli. This partial view of the person as an information-encoding machine (one is conscious of oneself insofar as, and in the ways that, one is different) is used to derive four predictions implying that ethnic identity is salient in children's spontaneous self-concepts to the extent that their ethnic group is in the minority in their social milieu at school. Our measure of salience of ethnicity was its being spontaneously mentioned by the children in response to a nondirective "Tell us about yourself" question. All four predictions were confirmed, though for several of the findings there are plausible alternative explanations.

Mental health, race and ethnicity: a retrospective study of the care of ethnic minorities and whites in a psychiatric unit.

A retrospective case-note study of 152 discharged psychiatric patients (77 subjects of ethnic minority origin and 75 whites) examined for details of follow-up arrangements on discharge, compliance rate with out-patient appointments and details on length of stay, status on admission, employment status, record of illicit drug taking and diagnosis. The results show that in the areas of diagnosis, possible illicit drug involvement, status on admission and length of stay, there are significant differences between Afro-Caribbean subjects and others.

Alcoholism and ethnicity: a comparative study of alcohol use patterns across ethnic groups.

Sociological and alcohol use patterns were studied in American Indian, Black, Hispano, and White Anglo groups of alcoholism patients. Sociological variables indicated all groups appeared to be experiencing significant disruption in social and vocational areas, with the American Indian group showing the greatest disruption across the four groups in the socioeconomic areas. The four groups did not differ as to use of alcohol to enhance self, manage anxiety and depression, or as to sustained or periodic use. American Indians and Hispanos have a greater tendency to drink gregariously, to drink more, and to have more disruption in social role functioning. The general trend was that the American Indian group revealed greater social and alcohol symptom disruption than the other three groups, thus supporting a more specialized treatment approach for American Indian alcoholism patients.

Patient Ethnicity and Staff Use of Restraints and Restrictive Practice in Inpatient Psychiatric Services: A Systematic Review.

Restrictive practices such as restraints, seclusion, and forced medication are only intended to be used when the threat is at a level whereby an individual is likely to inflict harm on themselves or another individual. Demographic variations, including ethnicity, may be associated with the use of these practices. However, there is no systematic review on patient ethnicity specifically. The review therefore aimed to establish whether a patient's ethnic identity was associated with staff use of restrictive practices in inpatient psychiatric services. The systematic review followed the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Four databases were searched (PsycINFO, Medline, Embase, and CINAHL). Methodological quality was assessed using the Critical Appraisal Skills Program Checklists. Fifteen studies met the inclusion criteria. A variety of ethnicities were identified within the studies. These were driven by the location of the study. Seclusion (14 studies), forced medication (4), and physical restraint (4) were explored. There were mixed findings, with ethnicity shown to predict restrictive practices in studies having larger participant numbers, longer follow-up periods and less methodological bias. It remains unclear whether ethnicity is a genuinely independent predictor of restraint and coercive practices or interacts with other risk factors. Staff working in inpatient settings should be aware of how unconscious biases might affect clinical practice. Recruiting a diverse workforce from minority ethnic groups into inpatient psychiatric services would be a positive step. However, support for these staff members is important, and all staff should be equipped to respond to ethnic diversity. Future research should explore beyond patient-level factors.

Comparison of restriction fragment length polymorphisms of proto-oncogenes in native Hawaiians and other ethnic groups in Hawaii.

The relative genetic diversity of selected proto-oncogenes in the native Hawaiian gene pool was examined by comparing the restriction fragment length polymorphisms of these genes in a group of 23 individuals with at least part Hawaiian ancestry, and in 20 individuals from other ethnic groups. Twenty-one combinations of the proto-oncogenes, c-fms, c-myc, L-myc, c-Ha-ras, and c-Ki-ras, tested with 1 or more of the restriction enzymes Bam HI, Eco RI, Hind III, Pst I, Pvu I and Kpn I were examined. Sixteen of these did not exhibit RFLPs in Hawaiians or in other ethnic groups. Four of the combinations exhibiting RFLPs in native Hawaiians exhibited similar-sized restriction fragments in the other ethnic groups. Only in the case of c-myc digested with Pst I were 5 individuals of Hawaiian ancestry found to have an RFLP which has not been detected in other ethnic groups. These 5 cases exhibited a 13-kb c-myc fragment in addition to the 5.5-kb fragment found in most Hawaiians and always present in other ethnic groups. The presence in Hawaiians of most RFLPs found in other ethnic groups indicates that the genetic diversity of proto-oncogenes in the gene pool of native Hawaiians is not substantially less than that of other ethnic groups.

Survival by Race and Ethnicity in Children and Adolescents/Young Adults With Relapsed/Refractory Hodgkin Lymphoma: A Pooled Analysis of Children's Oncology Group Trials.

PURPOSE: Despite 5-year survival rates of over 90% among children and adolescents/young adults (CAYAs) with classic Hodgkin lymphoma (cHL), 15%-20% relapse after frontline therapy. Prior analysis of frontline Children's Oncology Group (COG) clinical trials demonstrated that, despite similar rates of relapse, non-Hispanic Black (NHB) and Hispanic (vs. non-Hispanic White [NHW]) patients experienced higher post-relapse mortality. It is unknown whether post-relapse disparities persist when second-line treatment is delivered in a cooperative group trial setting. We examined overall survival (OS) by race and ethnicity in CAYAs enrolled in COG trials for relapsed/refractory (r/r) cHL. METHODS: A pooled analysis of individual-level data from CAYAs (≤ 29 years) receiving therapy for r/r cHL on COG clinical trials (2001-2016) was conducted. The Kaplan-Meier method estimated 3-year OS by racial and ethnic groups. Cox regression models examined associations of race and ethnicity and OS, adjusted for age, insurance, first versus ≥2 relapse, and time from initial diagnosis to relapse trial enrollment. RESULTS: Among 175 CAYAs treated on COG trials for r/r cHL (5.7% Asian or Pacific Islander, 14.9% Hispanic, 14.3% NHB, 61.7% NHW, 3.4% other), at median follow-up of 4.9 years, 3-year OS was 82.1% (95% confidence interval [CI], 75.3%-87.1%) and did not differ by race and ethnicity (p = 0.36). In multivariable analyses, shorter time from diagnosis to relapse trial enrollment (p = 0.01) and ≥2 relapses (vs. first, p = 0.004) conferred worse OS, with no significant effect of race and ethnicity (p = 0.43). CONCLUSION: Post-relapse survival did not differ by race and ethnicity among CAYAs enrolled in COG trials for r/r cHL, suggesting access to clinical trials may mitigate OS disparities.

A Systematic Review of Help-Seeking Barriers for Racial-Ethnic Minority Caregivers Accessing Autism Diagnostic and Intervention Services.

Caregivers play an essential role in early help-seeking and intervention for children with Autism Spectrum Disorder (ASD). Caregivers, therefore, provide a crucial role in helping to address the racial and ethnic disparity identified in accessing ASD intervention and diagnostic services (Bejarano-Martín et al., Journal of Autism and Developmental Disorders 50(9), 3380-3394, 2020). Unfortunately, racial-ethnic minority caregivers of children with autism (CCA) are less likely to contact a physician or healthcare professionals about their concerns and more likely to delay their contact to have their child evaluated (Zeleke et al., Journal of Autism and Developmental Disorders 49(10), 4320-4331, 2019). However, little evidence exists to explain why such a gap exists in the help-seeking behaviors between White and racial-ethnic minority CCA. To address this knowledge gap, we conducted a systematic literature review to identify articles that have studied barriers in help-seeking for racial-ethnic minority CCA. A broad literature search across four databases was conducted (i.e., PubMed, PsycINFO, Education Resources Information Center, and Child Development and Adolescent Studies). The coding team identified 17 articles on help-seeking barriers for racial-ethnic minority CCA. A thematic analysis was used to narratively synthesize the help-seeking barriers identified across these 17 studies. Four themes emerged from our findings: logistical barriers, provider competence, ASD literacy, and cultural stigma. We also provided clinical recommendations for healthcare providers working with families with racial-ethnic minority CCA.

Ethnic density and psychiatric hospitalization: hazards of minority status.

The relationship between ethnic density (the relative size of a given ethnic group in a multi-ethnic neighborhood) and risk for psychiatric hospitalization was explored for black, white, and Puerto Rican residents of New York City's 338 health areas. The author found that the smaller the ethnic group, the higher its hospitalization rate in comparison to both the rate of other residents in the same area and that of members of the same ethnic group living in areas where they constituted a numerical majority. Analysis of sociodemographic variables showed that the effect of ethnic density on risk for psychiatric hospitalization cannot be accounted for by differences in poverty, family cohesiveness, or population mobility.

Evaluation of the SLC11A1 non-synonymous variant rs17235409 and tuberculosis susceptibility in a multi-ethnic population from southwestern China.

Tuberculosis (TB) remains a major infectious disease burden, and inter-individual heterogeneity in progression from exposure to active disease suggests contributions from host genetic factors. SLC11A1 (formerly NRAMP1) encodes a phagosomal divalent cation transporter implicated in macrophage-mediated antimicrobial defense; the non-synonymous rs17235409 polymorphism (D543N) has been evaluated in multiple populations with inconsistent results. We conducted a retrospective matched case-control study in Qiandongnan, Guizhou Province, China, including 50 patients diagnosed with TB (2022-2023) and 50 healthy controls frequency-matched by ethnicity and selected demographics. Participants were drawn from Miao, Dong, and other minority groups. Among TB cases, the frequencies of the GG, GA, and AA genotypes were 80.0%, 20.0%, and 0%, respectively, compared with 74.0%, 18.0%, and 8.0% among controls. The overall genotype distribution did not differ significantly between the 2 groups (P = .124). Under the dominant model, no significant association was observed between rs17235409 and TB susceptibility (OR = 0.71, 95% CI: 0.28-1.82; P = .635). Allelic analysis showed that the frequency of the A allele was lower in cases than in controls (10.0% vs 17.0%), but this difference was not statistically significant (OR = 0.54, 95% CI: 0.24-1.25; P = .214). Ethnicity-stratified analyses similarly showed no statistically detectable associations in Miao, Dong, or other groups. The minor allele frequency was 0.095, lower than the Han Chinese reference from 1000 Genomes. In this pilot study of multi-ethnic populations from southwestern China, no statistically significant association was identified between the SLC11A1 rs17235409 polymorphism and tuberculosis susceptibility. Although the A allele appeared less frequent among cases, the limited sample size and statistical power preclude definitive conclusions regarding modest or ethnic-specific effects. These findings provide preliminary genetic data from underrepresented ethnic minority populations and warrant validation in larger multicenter studies.

Vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome: A comprehensive review of cases across different ethnicities.

OBJECTIVES: Vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) is an autoinflammatory disease associated with somatic mutations in the UBA1 gene. Although the disease has been described in many different countries, no studies have investigated the origin of patients to determine if the disease is universal across ancestries. The aim of this study is to investigate the distribution of VEXAS syndrome across continents and ethnicities. METHODS: A literature review of all reported cases of VEXAS syndrome was conducted between October 2020 and April 2025 using the term 'VEXAS' with the all-field filter in the Pubmed and Web of Science databases. Epidemiological and clinical data were collected for included patients. If the country of origin was not described, it was assumed to be the same as the country of clinical evaluation. A subgroup analysis was performed for patients whose country of origin or ethnicity was documented by the authors. RESULTS: 674 cases of VEXAS syndrome were collected, with patients described from four continents and 32 countries. Considering the subgroup of patients with documented country of origin, 451 patients were from four continents and 19 countries. Of these, ethnicity was recorded for 372 patients with the presence of Caucasian, Central or East Asian, South Asian, Middle Eastern, Central American and South American ethnicities. CONCLUSION: The results support a broad global distribution of the disease and highlight the importance of investigating the disease regardless of the patient's origin and ethnicity in cases of compatible symptoms.

The global prevalence of horizontal strabismus: A systematic review and meta-analysis with a focus on ethnic variation.

The prevalence of the 2 types of horizontal strabismus, esotropia and exotropia, varies considerably between studies. This variability has been attributed to factors such as geography/environment, research methodology, age of study subjects, and/or ethnicity. Comprehensive estimates of regional and global prevalences of esotropia and exotropia are lacking, making it difficult to recognize true patterns, trends, and etiologies. We compile prevalences and ratios of esotropia to exotropia from 315 population-based studies and 374 clinic-based studies. We analyze data to assess effects of ethnicity, geography, age, and we identify generational changes of horizontal strabismus. Major ethnicities differ in patterns and ratios of esotropia and exotropia prevalence, not only in Caucasians and East Asians, but also Latinos/Hispanics, South Asians, Africans, and Native Americans. Compared to population-based studies, clinic-based studies underestimate exotropia frequency. By weighing prevalences according to the population size of ethnicities, we estimate the worldwide prevalence of horizontal strabismus in the current generation at 1.81% (138.5 million people), comprising 60.0 million people with esotropia (0.67%) and 87.5 million with exotropia (1.14%). In the previous generation, the worldwide prevalence of horizontal strabismus was 1.64% (86.5 million people), comprising 50.5 million with esotropia (0.96%) and 36.0 million with exotropia (0.68%). Esotropia and exotropia prevalences differ between generations within the same ethnicity, indicating that extrinsic factors can modify the underlying intrinsic (genetic) disposition.

Intolerance and extremism in a correctional institution: a perceived ethnic relations approach.

The authors used an ecological approach to analyze the interaction of ethnicity, environment, personality, and ideology that led to racial intolerance, ethnic strife, and the existence of a self-styled neo-Nazi group in a correctional institution for youthful offenders. Staff members completed a questionnaire on which they rated the behavior of each of 320 inmates toward his own and other ethnic groups. The inmate's membership, if any, in a "power" subgroup was also noted. Results indicated a correlation between antagonistic patterns of ethnic relations and receptivity to racial propaganda and ideology. Further research focusing on the perceived ethnic relations climate is necessary to determine whether the patterns found in this institution are typical and to ascertain explanations for this correlation.

Molecular alterations in TP53, WNT, PI3K, TGF-Beta and RTK/RAS pathways in gastric cancer among ethnically heterogeneous cohorts.

BACKGROUND/OBJECTIVES: Gastric cancer (GC) remains a leading cause of cancer-related mortality worldwide, with significant racial and ethnic disparities in incidence, molecular characteristics, and patient outcomes. However, genomic studies focusing on Hispanic/Latino (H/L) populations remain scarce, limiting our understanding of ethnicity-specific molecular alterations. This study aims to characterize pathway-specific mutations in TP53, WNT, PI3K, TGF-Beta and RTK/RAS signaling pathways in GC and compare mutation frequencies between H/L and Non-Hispanic White (NHW) patients. Additionally, we evaluate the impact of these alterations on overall survival using publicly available datasets. METHODS: We conducted a bioinformatics analysis using publicly available GC datasets to assess mutation frequencies in TP53, WNT, PI3K, TGF-Beta and RTK/RAS pathway genes. A total of 800 patients were included in the analysis, comprising 83 H/L patients and 717 NHW patients. Patients were stratified by ethnicity (H/L vs. NHW) to evaluate differences in mutation prevalence. Chi-squared tests were performed to compare mutation rates between groups, and Kaplan-Meier survival analysis was used to assess overall survival differences based on pathway alterations among both H/L and NHW patients. RESULTS: Significant differences were observed in the TP53 pathway and related genes when comparing GC in H/L patients to NHW patients. TP53 mutations were less prevalent in H/L patients (9.6% vs. 19%, p = 0.03). Borderline significant differences were noted in the WNT pathway when comparing GC in H/L patients to NHW GC patients, with WNT alterations more frequent in H/L GC (8.4% vs. 4%, p = 0.08), and APC mutations significantly higher (3.6% vs. 0.8%, p = 0.05). Although alterations in PI3K, TGF-Beta and RTK/RAS pathways were not statistically significant, borderline significance was observed in genes related to these pathways, including EGFR (p = 0.07), FGFR1 (p = 0.05), FGFR2 (p = 0.05), and PTPN11 (p = 0.05) in the PI3K pathway, and SMAD4 (p = 0.08) in the TGF-Beta pathway. Survival analysis revealed no significant differences among H/L patients. However, NHW patients with TP53 and PI3K pathway alterations exhibited significant differences in overall survival, while those without TGF-Beta pathway alterations also showed a significant survival impact. In contrast, WNT pathway alterations were not associated with significant survival differences. These findings suggest that TP53, PI3K, and TGF-Beta pathway disruptions may have distinct prognostic implications in NHW GC patients. CONCLUSIONS: This study provides one of the first ethnicity-focused analyses of TP53, WNT, PI3K, TGF-Beta and RTK/RAS pathway alterations in GC, revealing significant racial/ethnic differences in pathway dysregulation. The findings suggest that TP53 and WNT alterations may play a critical role in GC among H/L patients, while PI3K and TGF-Beta alterations may have greater prognostic significance in NHW patients. These insights emphasize the need for precision medicine approaches that account for genetic heterogeneity and ethnicity-specific pathway alterations to improve cancer care and outcomes for underrepresented populations.

Ethnic differences in family factors related to early drug initiation.

The literature on family predictors of substance use for the general population is reviewed and compared to findings for three specific ethnic groups: black, white and Asian Americans. Rates of substance use initiation are examined in a sample of 919 urban 5th-grade students. Ethnic differences on measures of family predictors are examined and significant ethnic differences are found on several of these factors. Finally, separate regressions for black, white and Asian American youths of family factors on the variety of substances initiated examine ethnic similarities and differences in predictors. The results demonstrate significant differences by ethnicity in family management practices, involvement in family activity, sibling deviance, parental disapproval of children's drinking and family structure. The regression equations identified unique as well as common predictors of the variety of substances initiated by the end of 5th grade. Implications of the results are discussed.

A genetic signal at 8q12.3 modulates GGT levels via the Runx1-CYP7B1 axis in female ethnic minorities from Guizhou.

Gamma-glutamyl transferase (GGT) regarded as a biomarker of liver dysfunction or excessive alcohol consumption; however, existing genome-wide association studies (GWAS) have been conducted predominantly in European populations and East Asian populations from Japan and the Taiwan region, with limited investigation in ethnic minorities from Guizhou Province. Previous genetic studies have demonstrated that Guizhou ethnic minorities share an East Asian genetic background while exhibiting specific genetic structures, a pattern that is also confirmed by our principal component analysis (PCA) results. We therefore performed a GWAS in this population and identified a genome-wide significant signal at 8q12.3 in female ethnic minorities from Guizhou. Fine-mapping and functional annotation analyses suggest that a regulatory pathway involving Runt-related transcription factor 1 (Runx1)-Cytochrome P450 family 7 subfamily B member 1 (CYP7B1)-cholesterol-reactive oxygen species (ROS)-glutathione (GSH) may contribute to the regulation of GGT levels. Mendelian randomization (MR) analyses further supported a causal relationship between GGT levels and autoimmune hepatitis (AIH). These findings uncover a genetic mechanism underlying GGT variation at 8q12.3 in female ethnic minorities from Guizhou, implicating a pathway linked to cholesterol metabolism and oxidative stress, and providing potential targets and insights for precision prevention and treatment of related diseases.

Fingerprint pattern frequencies in schizophrenics. Importance of ethnic origin and plexus visualization score ratings.

Our previous work with schizophrenics has suggested that the plexus visualization score (PVS), a characteristic derived from in vivo observation of skin capillaries, may be helpful in distinguishing between biologically different groups of patients. Preliminary fingerprint data demonstrated a significant difference in the frequency of whorls between high PVS and low PVS schizophrenics. A survey of fingerprints in control subjects revealed, however, that their ethnic background, even within the presumably 'mixed' Caucasian population of the USA, should also be taken into account. In the present study, the fingerprint pattern frequencies were, therefore, studied in 242 schizophrenics selected on the basis of both their ethnic origin and PVS ratings. Our results demonstrate a statistically significant difference in fingerprint pattern frequencies between high PVS and low PVS schizophrenics, even when they are matched for ethnic origin. The effect of the ethnic factor on fingerprint pattern frequencies in this patient sample is similar to the one previously reported for normal subjects.
