Background Ethnic minority patients experience a higher uterine fibroid disease burden and reduced access to minimally invasive myomectomy. Restrictive selection criteria may disproportionately exclude these patients from laparoscopic surgery. Methods This was a prospective service-evaluation database analysed retrospectively, including all conventional (non-robotic) laparoscopic myomectomies performed between January 2004 and December 2024 at a single UK university hospital. Primary outcomes were estimated blood loss (EBL), length of hospital stay (LOS) and operating time. Secondary outcomes were blood transfusion rate, conversion to laparotomy and analysis of fibroid burden by ethnicity. Outcomes were compared between patients with large fibroids (>10 cm), high-order fibroids (>10 fibroids removed), both and neither. We performed inferential descriptive statistics using SPSS v27 (SPSS Inc., Chicago, IL). Results Among 550 patients, 164 had large fibroids, 30 high-order fibroids, 18 both and 338 neither. Ethnic minority patients represented 77%, 93%, 89% and 72% of these groups, respectively. Mean EBL was higher in large fibroid (345 mL) and combined groups (483 mL) compared with neither (211 mL), without associated increases in transfusion, conversion to laparotomy, or LOS. Black African and Black Caribbean patients had greater fibroid burden and higher blood loss than Caucasian patients, reflecting disease severity rather than ethnicity as an independent determinant of outcome. Conclusions In a specialist setting, laparoscopic myomectomy is feasible and safe for patients with large and/or multiple fibroids, including those from ethnic minority backgrounds with higher disease burden. Expansion of access within appropriately resourced centres may help reduce inequities in fibroid care.

ABSTRACT Background Individuals from specific ethnic populations are at increased risk of developing psychosis. Although socio-environmental adversity is cited as the main cause, current theoretical perspectives remain limited. This study adds to the debate about psychosis excess, by examining the qualitative accounts and perspectives of racialised patients. Method Drawing on a phenomenological and life narratives approach, 13 semi-structured interviews were conducted with Black/Black-British Caribbean patients recovering from their first episode of psychosis. Interviews elicited key aspects of the patients’ lives and obtained their reflections on the perceived cause of their first episode. Interviews were analysed thematically. Results Seven themes captured the life events of the patients. These were: Interpersonal Relationships and Social Interactions; Employment; Hobbies and Personal Interests; Educational Attainment; Cannabis use; Migrating to England and Religiousness. Being mistreated by others, cannabis use, and the cumulative effect of all of life’s negative circumstances were cited as causes of their first episode. Discussion Our findings are discussed in the context of interpersonal trauma, cultural differences in the response to mental distress and social group theory. We also consider the role of cannabis use as a social process and the cumulative effect of negative life events. The limitations of this work are discussed along with recommendations for further research.

This study employs the Integrated Model of Behavioral Prediction (IMBP) to investigate factors that influence African American and Black Caribbean patients' decisions to participate in clinical trials and research studies. It also offers recommendations for improving clinical trial recruitment processes through targeted interventions. Nine focus groups (N = 48 participants) involving patients and clinical research coordinators (CRCs) were conducted. Thematic analysis was used to compare perspectives, revealing salient attitudes, beliefs, perceived norms, and perceived control regarding clinical trial participation. Findings indicate that both patients and CRCs share similar positive (e.g., personal relevance and altruism) and negative (e.g., medical mistrust and health risks) outcome beliefs. Notably, financial incentives emerged as a double-edged sword-while they motivated some participants, they repelled others who perceived them negatively. This underscores the need for a nuanced understanding of community values and clear communication about the purpose of incentives. Insights from patient focus group discussions about their social networks highlighted community-level concerns regarding severe health consequences and mistrust in medical research, which impacted their normative beliefs. Additionally, concerns about clinical trial features influenced participants' control beliefs. These insights suggest that addressing both motivational and control factors sensitively can enhance intervention messages. Ultimately, these findings can inform training programs to improve communication strategies for CRCs, aiming to boost recruitment of African American and Black Caribbean populations into clinical trials.

BackgroundPsychological therapy (PT) along with antipsychotic medication is the recommended first line of treatment for first-episode psychosis (FEP). We investigated whether ethnicity, clinical, pathways to care (PtC) characteristics, and access to early intervention service (EIS) influenced the offer, uptake, and type of PT in an FEP sample.MethodsWe used data from the Clinical Record Interactive Search-First Episode Psychosis study. Inferential statistics determined associations between ethnicity, clinical, PtC, and PT offer/uptake. Multivariable logistic regression estimated the odds of being offered a PT and type of PT by ethnicity, clinical and PtC characteristics adjusting for confounders.ResultsOf the 558 patients included, 195 (34.6%) were offered a PT, and 193 accepted. Cognitive behavioral therapy (CBT) (n = 165 of 195; 84.1%) was commonly offered than group therapy (n = 30 of 195; 13.3%). Patients who presented via an EIS (adj. OR = 2.24; 95%CI 1.39–3.59) were more likely to be offered a PT compared with those in non-EIS. Among the patients eligible for an EIS, Black African (adj. OR = 0.49; 95%CI = 0.25–0.94), Black Caribbean (adj. OR = 0.45; 95%CI = 0.21–0.97) patients were less likely to be offered CBT compared with their White British counterparts. Patients with a moderate onset of psychosis (adj. OR = 0.34; 95%CI = 0.15–0.73) had a reduced likelihood of receiving CBT compared with an acute onset.ConclusionsAccessing EIS during FEP increased the likelihood of being offered a PT. However, treatment inequalities remain by ethnicity and clinical characteristics.

Hypertension disproportionately affects individuals identifying as Black African, Black Caribbean, and Black other with higher rates of uncontrolled hypertension and related organ damage including stroke and kidney disease. Improved understanding of ethnic and cultural views about hypertension is needed to support medication adherence. To explore the adherence barriers and facilitators to taking antihypertensive medication in people of Black African or Black Caribbean heritage. Qualitative study with an electronic survey followed by semi-structured interviews in South East London. 11 participants were recruited with the support of public health and a community interest company; nine who completed an online survey and six who completed online interviews, regarding their experiences and thoughts around medical management of hypertension. Data were analysed using thematic analysis and then mapped to Capacity, Opportunity, and Motivation Behaviour (COM-B) model components. Substantial barriers exist to the adherence to antihypertensive medication for Black African and Black Caribbean patients in South East London owing to mistrust on both system and interpersonal levels. People felt uninvolved in treatment decisions and that there was a lack of discussion about non-medical management. Adherence was facilitated by an understanding of the consequences of not taking antihypertensive medication, although this was also associated with fear and mistrust. These barriers add new findings to existing studies on hypertension management and are congruent with current literature describing mistrust stemming from longstanding racial discrimination. Mapping to a COM-B model allows clinicians, and wider systems, to translate these findings into opportunities for interventions. Recommendations include patient-centred consultations to improve health literacy and shared decision making, trust-based engagement with communities and cultural awareness training.

The underrepresentation of ethnic minorities and low-income groups in primary care (PC) research hinders the development of effective treatments for diverse populations. To develop a framework that general practice staff and researchers can use to improve the participation of underserved groups in PC research. This study was undertaken across 10 GP practices in South London serving 150 658 patients. Practices are distributed across ethnically diverse and highly deprived communities. A mixed-methods approach was utilised. Retrospective data were collected on patient participation in research studies across the practices between July 2022 and July 2023. Professional and patient focus groups, and a patient questionnaire, were undertaken to understand awareness and knowledge of, enablers for, and barriers to research participation. Over the 12-month period, 627 patients participated in PC research studies across the 10 practices. Black African and Black Caribbean patients accounted for 26% of the practices' patient population but were significantly underrepresented in research, comprising only 11% of participants. Patients of Asian backgrounds accounted for 11% of the practices' population but made up 20% of research participants. Lack of awareness of research participation opportunities, fear of side effects, language barriers, and mistrust of researchers were some of the barriers to participation. Participants highlighted that trust in their GP, education, and transparency of research processes were key to building long-term engagement. This study provides insights into poor recruitment of specific ethnic minorities into primary care studies. The authors identified adaptations to research engagement activities, which are required to ensure that participation is improved.

This study investigates the role of source credibility on minority participant recruitment, particularly African American and Black Caribbean patients. A total of nine focus groups (N = 48 participants) were conducted with both patient groups and clinical research coordinators (CRCs). Using the elaboration likelihood model as a guiding framework for analysis, this study found that the credibility of research coordinators (or other professionals who recruit for research studies and clinical trials) was instrumental in shaping attitudes of prospective participants. The perspectives of patients and CRCs aligned closely, with few exceptions. For both groups, professionalism and professional displays (clothing, institutional artifacts) enhanced perceived expertise, a core component of credibility. Trustworthiness, another important component of credibility, was fostered through homophily between recruiter and patient, expressions of goodwill and assuaging anxiety about CRCs' financial motivations for recruitment. Additionally, CRCs believed that credibility was supported when CRCs could emphasize transparency and truthfulness in communication. The importance of these findings for the development of empirically-based training programs to improve communication practices in recruitment contexts is discussed.

ABSTRACT This manuscript focuses on the communication factors that affect the willingness of African Americans and Black Caribbean patients to participate in clinical trials and research studies. Low rates of research participation by members of communities of color have long been linked to health disparities. While there are many factors that contribute to low rates of accrual of African American and Black patients to clinical trials, a lack of attention to communication factors that enhance or inhibit the recruitment process is central to the problem. In this study, we describe results from the analysis of six focus groups (N = 31) consisting of African American (k = 3) and Black Caribbean (k = 3) participants. Our analyses focus on verbal and nonverbal communication behaviors and how they affect participants’ willingness to participate in clinical trials. Specifically, when clinical research coordinators (CRCs) had a professional appearance, made the effort to explain a study in detail, made eye contact, took the time to listen and answer questions patiently, and gave the sense that the CRC was being truthful and transparent, patients felt respected and valued. Additionally, participants emphasized the importance of the process of developing and maintaining a trusting relationship between study participants and CRCs. The results of this study will be used to develop a clinical trial communication training program designed to enhance the communication skills of clinical research coordinators who discuss research participation with African American and Caribbean Black patients.

Considerable concern has arisen during the Covid pandemic over the use of Do Not Attempt Cardiopulmonary Resuscitation decisions (DNACPRs) in England and Wales, particularly around the potential blanket application of them on older adults and those with learning disabilities. In this article, we set out the legal background to DNACPRs in England and the concerns raised during Covid. We also report on an empirical study that examined the use of DNACPRs across 23 Trusts in England, which found overall increases in the number of patients with a DNACPR decision during the two main Covid ‘waves’ (23 March 2020–31 January 2021) compared with the previous year. We found that these increases were largest among those in mid-life age groups, despite older patients (in particular, older women) having a higher number of DNACPR decisions overall. However, further analysis revealed that DNACPR decisions remained fairly consistent with regard to patient sex and age, with small reductions seen in the oldest age groups. We found that a disproportionate number of Black Caribbean patients had a DNACPR decision. Overall, approximately one in five patients was not consulted about the DNACPR decision, but during the first Covid wave more patients were consulted than pre-Covid.

Suicide rates by ethnic group among patients in contact with mental health services: an observational cohort study in England and Wales

Anal Squamous Cell Carcinoma (ASCC) is an HPV-related malignancy with increasing incidence in high-income economies. Although ethnicity and social deprivation are known to be risk factors in other malignancies, little is known about socioeconomic status and risk of ASCC. This is a cross-sectional study following the STROBE Statement. Demographic data from the English Clinical Outcomes and Services Dataset (COSD) were extracted for all patients diagnosed with ASCC in England between 2013 and 2018. Outcomes included ethnicity, social deprivation, staging and treatment. This study included 5457 patients. Incidence increased by 23.4% in 5 years, with female incidence increasing more rapidly than male incidence (28.6% vs. 13.5%). Men were more likely to present with early staging (p < 0.001) and have surgery as their only treatment (p < 0.001). The rate of incidence of Stage 1 tumours in men was 106.9%; however, women had the greatest increase in metastatic tumours (76.1%). Black Caribbean and Black African patients were more likely to present at an earlier age with later staging (p < 0.001) and social deprivation was associated with younger age (p < 0.001). ASCC incidence is rapidly increasing in patterns consistent with two separate populations: one male with early staging, the other female and related to social deprivation and ethnicity factors.

Dementia in People from Ethnic Minority Backgrounds: Disability, Functioning, and Pharmacotherapy at the Time of Diagnosis

Studies on excised aldosterone-producing lesions have found somatic mutations in five genes (KCNJ5, CACNA1D, ATP1A1, ATP2B3, and CTNNB1) commonly causes the excess aldosterone production. Interestingly, Oriental cohorts had the highest frequency of KCNJ5 mutations whereas CACNA1D mutations were most common in Black African Caribbean patients, suggesting that genetic background affects the prevalence and distribution of aldosterone-driving somatic mutation. We therefore aimed to identify the common germline variants that associates with excess aldosterone production through performing a pilot genome wide association study (GWAS) on primary aldosteronism (PA) patients. GWAS was performed using the Human Infinium OmniExpressExome-8 v1.4 BeadChip containing 960,919 markers to compare gDNA of 154 PA patients with 78 healthy controls. Samples were checked for sex discordance, heterozygosity rate, missing rate and the degree of recent shared ancestry for each pair of individuals using the PLINK program and Genome Studio (Illumina). In total, 150 patients and 75 controls (112 males and 113 females) were included in the downstream analysis. 630,749 markers that passed quality control steps (missing call rate <95% and minor allele frequency in controls >1%) were used to perform association analysis using the Chi-square Test which was then subjected to multiple testing corrections (Bonferroni correction). As expected with a pilot sample size, no variants passed the suggestive significant threshold of Bonferroni corrected P-value < 5 x 10-6 (-log10 P = 5.3). However, 27 SNPs had the uncorrected P-value<0.0002, odds ratio >2, and differences of frequencies in cases compared to control >0.1 or <-0.2, of which 3 genes (SRGAP3, AUTS2, and RORA) associated with these SNPs were also highlighted in the UK Biobank database of 72 patients with primary aldosteronism (https://biobankengine.stanford. edu/coding/HC189). Of these, RORA has recently been found to be down-regulated in adrenals from PA patients and spontaneously hypertensive rat adrenals compared to control adrenalsa,b. RORA encodes for the protein retinoic acid receptor (RAR)-related orphan receptor alpha, a member of the NR1 subfamily of nuclear hormone receptors (NR1F1). Interestingly, adrenal is the second organ to skin with the highest expression of RORA and treatment of angiotensin II in the adrenocortical cell line H295R increases RORA expressionc,d. Taken together, this pilot GWAS highlights RORA as a potential nuclear hormone receptor that regulates aldosterone production.References aChu et al., Int J Clin Exp Pathol 2017;10(9):10009-10018. bTanaka et al., Hypertens Res 2019;42(2):165-173. cNogueira et al., Mol Cell Endocrinol 2009; 302(2): 230–236. dGTEx Analysis Release V7 (dbGaP Accession phs000424.v7.p2)AcknowledgementsThis research was supported by the Malaysian Ministry of Higher Education Grant (FRGS/1/2015/SKK08/UKM/02/3), The National University of Malaysia (UKM) University Grant (GUP-2016-083), and The UKM Medical Center Fundamental Grant (FF-2016-302).

SummaryBackgroundEvidence suggests that black, Asian and minority ethnic (BAME) groups have an increased risk of involuntary psychiatric care. However, to our knowledge, there is no published meta-analysis that brings together both international and UK literature and allows for comparison of the two. This study examined compulsory detention in BAME and migrant groups in the UK and internationally, and aimed to expand upon existing systematic reviews and meta-analyses of the rates of detention for BAME populations.MethodsFor this systematic review and meta-analysis, we searched five databases (PsychINFO, MEDLINE, Cochrane Controlled Register of Trials, Embase, and CINAHL) for quantitative studies comparing involuntary admission, readmission, and inpatient bed days between BAME or migrant groups and majority or native groups, published between inception and Dec 3, 2018. We extracted data on study characteristics, patient-level data on diagnosis, age, sex, ethnicity, marital status, and occupational status, and our outcomes of interest (involuntary admission to hospital, readmission to hospital, and inpatient bed days) for meta-analysis. We used a random-effects model to compare disparate outcome measures. We assessed explanations offered for the differences between minority and majority groups for the strength of the evidence supporting them. This study is prospectively registered with PROSPERO, number CRD42017078137.FindingsOur search identified 9511 studies for title and abstract screening, from which we identified 296 potentially relevant full-text articles. Of these, 67 met the inclusion criteria and were reviewed in depth. We added four studies after reference and citation searches, meaning 71 studies in total were included. 1 953 135 participants were included in the studies. Black Caribbean patients were significantly more likely to be compulsorily admitted to hospital compared with those in white ethnic groups (odds ratio 2·53, 95% CI 2·03–3·16, p<0·0001). Black African patients also had significantly increased odds of being compulsorily admitted to hospital compared with white ethnic groups (2·27, 1·62–3·19, p<0·0001), as did, to a lesser extent, south Asian patients (1·33, 1·07–1·65, p=0·0091). Black Caribbean patients were also significantly more likely to be readmitted to hospital compared with white ethnic groups (2·30, 1·22–4·34, p=0·0102). Migrant groups were significantly more likely to be compulsorily admitted to hospital compared with native groups (1·50, 1·21–1·87, p=0·0003). The most common explanations for the increased risk of detainment in BAME populations included increased prevalence of psychosis, increased perceived risk of violence, increased police contact, absence of or mistrust of general practitioners, and ethnic disadvantages.InterpretationBAME and migrant groups are at a greater risk of psychiatric detention than are majority groups, although there is variation across ethnic groups. Attempts to explain increased detention in ethnic groups should avoid amalgamation and instead carry out culturally-specific, hypothesis-driven studies to examine the numerous contributors to varying rates of detention.FundingUniversity College London Hospitals National Institute for Health Research (NIHR) Biomedical Research Centre, NIHR Biomedical Research Centre at South London and Maudsley NHS Foundation Trust, King's College London, and NIHR Collaboration for Leadership in Applied Health Research and Care North Thames at Bart's Health NHS Trust.

ObjectivesCompared with the majority population, those from minority ethnic groups in the UK are more likely to be admitted compulsorily during a first episode of psychosis (FEP). We investigated whether these disparities in pathways in to care continue.MethodsWe analysed data from two first episode psychosis studies, conducted in the same geographical area in south London 15 years apart: the Aetiology and Ethnicity in Schizophrenia and Other Psychosis (AESOP) and the Clinical Record Interactive Search-First Episode Psychosis (CRIS-FEP) studies. The inclusion/exclusion criteria for case ascertainment for first episode psychosis were identical across the two studies. We performed multivariable logistic regression to estimate odds of compulsory admission by ethnic group, controlling for confounders.ParticipantsTwo hundred sixty-six patients with first episode psychosis, aged 18–64 years, who presented to mental health services in south London in 1997–1999 and 446 with FEP who presented in 2010–2012.ResultsWhen the two samples were compared, ethnic differences in compulsory admission appear to have remained the same for black African patients, i.e. three times higher than white British in both samples: AESOP (adj. OR = 3.96; 95% CI = 1.80–8.71) vs. CRIS-FEP (adj. OR = 3.12; 95% CI = 1.52–6.35). Black Caribbean patients were three times more likely to be compulsorily admitted in AESOP (adj. OR = 3.20; 95% CI = 1.56–6.54). This was lower in the CRIS-FEP sample (adj. OR = 1.68; 95% CI = 0.71–3.98) and did not meet conventional levels for statistical significance.ConclusionEthnicity is strongly associated with compulsory admissions at first presentation for psychosis with evidence of heterogeneity across groups, which deserves further research.

BackgroundAs part of a national programme to tackle ethnic inequalities, we conducted a systematic review and meta-analysis of research on ethnic inequalities in pathways to care for adults with psychosis living in England and/or Wales.MethodsNine databases were searched from inception to 03.07.17 for previous systematic reviews, including forward and backward citation tracking and a PROSPERO search to identify ongoing reviews. We then carried forward relevant primary studies from included reviews (with the latest meta-analyses reporting on research up to 2012), supplemented by a search on 18.10.17 in MEDLINE, Embase, PsycINFO and CINAHL for primary studies between 2012 and 2017 that had not been covered by previous meta-analyses.ResultsForty studies, all conducted in England, were included for our updated meta-analyses on pathways to care. Relative to the White reference group, elevated rates of civil detentions were found for Black Caribbean (OR = 3.43, 95% CI = 2.68 to 4.40, n = 18), Black African (OR = 3.11, 95% CI = 2.40 to 4.02, n = 6), and South Asian patients (OR = 1.50, 95% CI 1.07 to 2.12, n = 10). Analyses of each Mental Health Act section revealed significantly higher rates for Black people under (civil) Section 2 (OR = 1.53, 95% CI = 1.11 to 2.11, n = 3). Rates in repeat admissions were significantly higher than in first admission for South Asian patients (between-group difference p < 0.01). Some ethnic groups had more police contact (Black African OR = 3.60, 95% CI = 2.15 to 6.05, n = 2; Black Caribbean OR = 2.64, 95% CI = 1.88 to 3.72, n = 8) and criminal justice system involvement (Black Caribbean OR = 2.76, 95% CI = 2.02 to 3.78, n = 5; Black African OR = 1.92, 95% CI = 1.32 to 2.78, n = 3). The White Other patients also showed greater police and criminal justice system involvement than White British patients (OR = 1.49, 95% CI = 1.03 to 2.15, n = 4). General practitioner involvement was less likely for Black than the White reference group. No significant variations over time were found across all the main outcomes.ConclusionsOur updated meta-analyses reveal persisting but not significantly worsening patterns of ethnic inequalities in pathways to psychiatric care, particularly affecting Black groups. This provides a comprehensive evidence base from which to inform policy and practice amidst a prospective Mental Health Act reform.Trial registrationCRD42017071663

BackgroundResearch evaluating lifestyle interventions for prevention of cardiovascular disease (CVD) may not reach those most at risk. We compared the response rate to a randomised controlled trial (RCT) of a lifestyle intervention by CVD risk, ethnicity and level of deprivation.MethodsPrimary care patients with a QRisk2 score ≥ 20% were invited to participate in a RCT of an intensive lifestyle intervention versus usual care. This cross-sectional analysis compares anonymised data of responders and non-responders with multiple logistic regression, using adjusted odds ratios (AORs) for QRisk2 score, ethnicity, Index of Multiple Deprivation (IMD 2010) quintile, age and sex.ResultsFrom 60 general practices, 8902 patients were invited and 1489 responded. The mean age was 67.3 years and 21.0% were female. Of all patients invited, 69.9% were of white ethnic background, 13.9% ethnic minority backgrounds and 16.2% had no ethnicity data recorded in their medical records. Likelihood of response decreased as QRisk2 score increased (AOR 0.82 per 5 percentage points, 95% CI 0.77–0.88). Black African or Caribbean patients (AOR 0.67; 95% CI 0.45–0.98) and those with missing ethnicity data (AOR 0.55; 95% CI 0.46–0.66) were less likely to respond compared to participants of white ethnicity, but there was no difference in the response rates between south Asian and white ethnicity (AOR 1.08; 95% CI 0.84–1.38). Patients residing in the fourth (AOR 0.70; 95% CI 0.56–0.87) and fifth (AOR 0.52; 95% CI 0.40–0.68) most deprived IMD quintile were less likely to respond compared to the least deprived quintile.ConclusionsEvaluations of interventions intended for those at high risk of CVD may fail to reach those at highest risk. Hard to reach patient groups may require different recruitment strategies to maximise participation in future trials. Improvements in primary care ethnicity data recording is required to aid understanding of how successfully study samples represent the target population.Trial registrationISRCTN, ISRCTN84864870.

BackgroundThe incidence of psychotic disorders is elevated in some minority ethnic populations. However, we know little about the outcome of psychoses in these populations.AimsTo investigate patterns and determinants of long-term course and outcome of psychoses by ethnic group following a first episode.MethodÆSOP-10 is a 10-year follow-up of an ethnically diverse cohort of 532 individuals with first-episode psychosis identified in the UK. Information was collected, at baseline, on clinical presentation and neurodevelopmental and social factors and, at follow-up, on course and outcome.ResultsThere was evidence that, compared with White British, Black Caribbean patients experienced worse clinical, social and service use outcomes and Black African patients experienced worse social and service use outcomes. There was evidence that baseline social disadvantage contributed to these disparities.ConclusionsThese findings suggest ethnic disparities in the incidence of psychoses extend, for some groups, to worse outcomes in multiple domains.

BackgroundStroke incidence is increased in Black individuals but the reasons for this are poorly understood. Exploring the differences in aetiological stroke subtypes, and the extent to which they are explained by conventional and novel risk factors, is an important step in elucidating the underlying mechanisms for this increased stroke risk.MethodsBetween 1999 and 2010, 1200 black and 1200 white stroke patients were prospectively recruited from a contiguous geographical area in South London in the UK. The Trial of Org 10172 (TOAST) classification was used to classify stroke subtype. Age- and sex-adjusted comparisons of socio-demographics, traditional vascular risk factors and stroke subtypes were performed between black and white stroke patients and between Black Caribbean and Black African stroke patients using age-, sex-, and social deprivation-adjusted univariable and multivariable logistic regression analyses.ResultsBlack stroke patients were younger than white stroke patients (mean (SD) 65.1 (13.7) vs. 74.8 (13.7) years). There were significant differences in the distribution of stroke subtypes. Small vessel disease stroke was increased in black patients versus white patients (27 % vs. 12 %; OR, 2.74; 95 % CI, 2.19–3.44), whereas large vessel and cardioembolic stroke was less frequent in black patients (OR, 0.59; 95 % CI, 0.45–0.78 and OR, 0.61; 95 % CI, 0.50–0.74, respectively). These associations remained after controlling for traditional vascular risk factors and socio-demographics. Black Caribbean patients appeared to have an intermediate risk factor and stroke subtype profile between that found in Black African and white stroke patients. Cardioembolic stroke was more strongly associated with Black Caribbean ethnicity versus Black African ethnicity (OR, 1.48; 95 % CI, 1.04–2.10), whereas intracranial large vessel disease was less frequent in Black Caribbean patients versus Black African subjects (OR, 0.44; 95 % CI, 0.24–0.83).ConclusionsClear differences exist in stroke subtype distribution between black and white stroke patients, with a marked increase in small vessel stroke. These could not be explained by differences in the assessed traditional risk factors. Possible explanations for these differences might include variations in genetic susceptibility, differing rates of control of vascular risk factors, or as yet undetermined environmental risk factors.

Studies have linked ethnic differences in depression rates with neighbourhood ethnic density although results have not been conclusive. We looked at this using a novel approach analysing whole population data covering just over one million GP patients in four London boroughs. Using a dataset of GP records for all patients registered in Lambeth, Hackney, Tower Hamlets and Newham in 2013 we investigated new diagnoses of depression and antidepressant use for: Indian, Pakistani, Bangladeshi, black Caribbean and black African patients. Neighbourhood effects were assessed independently of GP practice using a cross-classified multilevel model. Black and minority ethnic groups are up to four times less likely to be newly diagnosed with depression or prescribed antidepressants compared to white British patients. We found an inverse relationship between neighbourhood ethnic density and new depression diagnosis for some groups, where an increase of 10% own-ethnic density was associated with a statistically significant (p < 0.05) reduced odds of depression for Pakistani [odds ratio (OR) 0.81, 95% confidence interval (CI) 0.70-0.93], Indian (OR 0.88, CI 0.81-0.95), African (OR 0.88, CI 0.78-0.99) and Bangladeshi (OR 0.94, CI 0.90-0.99) patients. Black Caribbean patients, however, showed the opposite effect (OR 1.26, CI 1.09-1.46). The results for antidepressant use were very similar although the corresponding effect for black Caribbeans was no longer statistically significant (p = 0.07). New depression diagnosis and antidepressant use was shown to be less likely in areas of higher own-ethnic density for some, but not all, ethnic groups.
