BackgroundThere has been a relative dearth of epidemiological research into bipolar affective disorder. Furthermore, incidence studies of bipolar disorder have been predominantly retrospective and most only included hospital admission cases.AimsTo determine the incidence of operationally defined bipolar disorder in three areas of the UK and to investigate any differences in gender and ethnicity.MethodAll patients who contacted mental health services with first-episode psychosis or non-psychotic mania between September 1997 and August 1999 were identified and diagnosed according to ICD–10 criteria. Incidence rates of bipolar affective disorder were standardised for age and stratified by gender and ethnic group across the three areas.ResultsThe incidence rate per 100 000 per year in south-east London was over twice that in Nottingham and Bristol. There was no significant difference in the rates of disorder in men and women. Incidence rates of bipolar disorder in the combined Black and minority ethnic groups in all three areas were significantly higher than those of the comparison White groups.ConclusionsThe incidence of bipolar disorder was higher in south-east London than in the other two areas, and was higher among Black and minority ethnic groups than in the White population.

Toxocariasis in humans is a little-studied zoonosis, and there are no data on the impact of this parasitosis on the minority groups in our country. The purpose of this study is to establish the seroprevalence of toxocariasis among ethnic groups in the Varna region, North-eastern Bulgaria, and compare the results with a control group from the general population. Material/Methods: As a part of a large seroepidemiologic study, we assessed the presence of Toxocara IgG among 132 individuals, self-identified with Turkish and Roma ethnicities. As a control group, we used 250 sera from children and adults from a control group. The statistical comparison was performed regarding age, sex, and type of residence. Results: Toxocara IgG were established in 43 individuals from the minority groups (seroprevalence of 32.58%) and 39 persons in the control group (15.60%) with а statistically significant difference (odds ratio = 2.61). Considerably high seropositivity in the investigated ethnicities was discovered after separating by age: children-33.33%; adults-32.00% and gender: male-38.98%; female-27.40%. A detailed analysis revealed that the type of settlement is an important confounding factor. The seropositivity among the minority ethnic groups residing in small towns and villages is 35,40%, in contrast to the residents of Varna city of the same ethnical origin (15.79%); OR = 2.92. Conclusion: The established high seroprevalence for Toxocara IgG among minority ethnic groups, especially those residing in the rural settlements of North-eastern Bulgaria, shows undiscovered to this point increased risk for the spread of toxocariasis among this population.

The incidence of psychotic disorders is increased, to varying extents, in many migrant and minority ethnic populations in several countries. This chapter briefly reviews the evidence on disparities in incidence between minority and majority populations and then discusses possible explanations. It is unlikely that methodological artifact, including misdiagnosis, can fully account for the high incidence rates observed in some populations. Further, there is no evidence that established neurodevelopmental risk factors for psychosis explain disparities among ethnic groups. It is, then, most likely—and there is growing evidence to support this—that the high rates are a consequence of greater exposure to adverse social conditions and experiences, particularly those involving threat and violence, over the life course among minority ethnic groups. In other words, psychosis occurs more often in some minority populations via a socio-developmental pathway.

Abstract Background In Europe, the incidence of psychotic disorder is high in certain migrant and minority ethnic groups (hence: ‘minorities’). However, it is unknown how the incidence pattern for these groups varies within this continent. Our objective was to compare, across sites in France, Italy, Spain, the UK and the Netherlands, the incidence rates for minorities and the incidence rate ratios (IRRs, minorities v. the local reference population). Methods The European Network of National Schizophrenia Networks Studying Gene–Environment Interactions (EU-GEI) study was conducted between 2010 and 2015. We analyzed data on incident cases of non-organic psychosis (International Classification of Diseases, 10th edition, codes F20–F33) from 13 sites. Results The standardized incidence rates for minorities, combined into one category, varied from 12.2 in Valencia to 82.5 per 100 000 in Paris. These rates were generally high at sites with high rates for the reference population, and low at sites with low rates for the reference population. IRRs for minorities (combined into one category) varied from 0.70 (95% CI 0.32–1.53) in Valencia to 2.47 (95% CI 1.66–3.69) in Paris (test for interaction: p = 0.031). At most sites, IRRs were higher for persons from non-Western countries than for those from Western countries, with the highest IRRs for individuals from sub-Saharan Africa (adjusted IRR = 3.23, 95% CI 2.66–3.93). Conclusions Incidence rates vary by region of origin, region of destination and their combination. This suggests that they are strongly influenced by the social context.

Minority ethnic groups have been disproportionately affected by the COVID-19 pandemic. While the exact reasons for this remain unclear, they are likely due to a complex interplay of factors rather than a single cause. Reducing these inequalities requires a greater understanding of the causes. Research to date, however, has been hampered by a lack of theoretical understanding of the meaning of ‘ethnicity’ (or race) and the potential pathways leading to inequalities. In particular, quantitative analyses have often adjusted away the pathways through which inequalities actually arise (ie, mediators for the effect of interest), leading to the effects of social processes, and particularly structural racism, becoming hidden. In this paper, we describe a framework for understanding the pathways that have generated ethnic (and racial) inequalities in COVID-19. We suggest that differences in health outcomes due to the pandemic could arise through six pathways: (1) differential exposure to the virus; (2) differential vulnerability to infection/disease; (3) differential health consequences of the disease; (4) differential social consequences of the disease; (5) differential effectiveness of pandemic control measures and (6) differential adverse consequences of control measures. Current research provides only a partial understanding of some of these pathways. Future research and action will require a clearer understanding of the multiple dimensions of ethnicity and an appreciation of the complex interplay of social and biological pathways through which ethnic inequalities arise. Our framework highlights the gaps in the current evidence and pathways that need further investigation in research that aims to address these inequalities.

Abstract Background Perceived discrimination is associated with worse mental health. Few studies have assessed whether perceived discrimination (i) is associated with the risk of psychotic disorders and (ii) contributes to an increased risk among minority ethnic groups relative to the ethnic majority. Methods We used data from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions Work Package 2, a population-based case−control study of incident psychotic disorders in 17 catchment sites across six countries. We calculated odds ratios (OR) and 95% confidence intervals (95% CI) for the associations between perceived discrimination and psychosis using mixed-effects logistic regression models. We used stratified and mediation analyses to explore differences for minority ethnic groups. Results Reporting any perceived experience of major discrimination (e.g. unfair treatment by police, not getting hired) was higher in cases than controls (41.8% v. 34.2%). Pervasive experiences of discrimination (≥3 types) were also higher in cases than controls (11.3% v. 5.5%). In fully adjusted models, the odds of psychosis were 1.20 (95% CI 0.91–1.59) for any discrimination and 1.79 (95% CI 1.19–1.59) for pervasive discrimination compared with no discrimination. In stratified analyses, the magnitude of association for pervasive experiences of discrimination appeared stronger for minority ethnic groups (OR = 1.73, 95% CI 1.12–2.68) than the ethnic majority (OR = 1.42, 95% CI 0.65–3.10). In exploratory mediation analysis, pervasive discrimination minimally explained excess risk among minority ethnic groups (5.1%). Conclusions Pervasive experiences of discrimination are associated with slightly increased odds of psychotic disorders and may minimally help explain excess risk for minority ethnic groups.
