Abstract
OBJECTIVE To systematically review the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) among Black children and adolescents compared to White, Latino and Asian children and adolescents. METHOD Peer-reviewed articles were identified in seven databases and included if they reported prevalence of ADHD among Black children and adolescents living in a minority context and compared rates to at least one of White, Latino or Asian samples. A total of 7050 articles were retrieved and 155 articles were subjected to full evaluation. Twenty-three studies representing 26 independent samples were included. RESULTS The pooled sample size was n = 218,445 (k = 26), n = 835,505 (k = 25), n = 493,417 (k = 24), and n = 66,413 (k = 7) of Black, White, Latino, and Asian participants, respectively. Pooled prevalence rate of ADHD was 15.9% (95%CI 11.6% - 20.7%) among Black children and adolescents, 16.6% (95%CI 11.6% - 22.2%) among Whites, 10.1% (95%CI 6.9% - 13.8%) among Latinos and 12.4% (95%CI 1.4% - 31.8%) among Asians. There was no significant difference in prevalence between ethnic groups, whereas both Black and White children and adolescents had marginally statistically significant higher prevalence than Asians. The results of a meta-regression analysis showed no moderating effects of the type of sample and the year of publication of studies. A significant publication bias was observed, suggesting that other moderators were not identified in the present systematic review. CONCLUSION In contrast to the assertion in the DSM-5 that clinical identification among Black children and adolescents is lower than among White children and adolescents, the present meta-analysis suggests similar rates of ADHD among these two groups. The importance of considering cultural appropriateness of assessment tools and processes is emphasized.

Abstract
OBJECTIVE Black communities are increasingly concerned about psychosis, a worry echoed by provincial health-care systems across Canada. Responding to the lack of evidence on psychosis in Black communities, this scoping review examined the incidence and prevalence of psychosis, access to care (pathways to care, coercive referrals, interventions, etc.), treatments received, and stigma faced by individuals with psychosis. METHOD To identify studies, a comprehensive search strategy was developed and executed in December 2021 across 10 databases, including APA PsycInfo, CINAHL, MEDLINE and Web of Science. Subject headings and keywords relating to Black communities, psychosis, health inequalities, Canada and its provinces and territories were used and combined. The scoping review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping review (PRISMA-ScR) reporting standard. RESULTS A total of 15 studies met the inclusion criteria, all of them conducted in Ontario and Quebec. Results highlight different disparities in psychosis among Black communities. Compared to other Canadian ethnic groups, Black individuals are more likely to be diagnosed with psychosis. Black individuals with psychosis are more likely to have their first contact with health-care settings through emergency departments, to be referred by police and ambulance services, and to experience coercive referrals and interventions, and involuntary admission. Black individuals experience a lower quality of care and are the ethnic group most likely to disengage from treatment. CONCLUSION This scoping review reveals many gaps in research, prevention, promotion and intervention on psychosis in Black individuals in Canada. Future studies should explore factors related to age, gender, social and economic factors, interpersonal, institutional and systemic racism, and psychosis-related stigma. Efforts should be directed toward developing trainings for health-care professionals and promotion and prevention programs within Black communities. Culturally adapted interventions, racially disaggregated data, and increased research funding are needed.

Abstract
BACKGROUND In Canada, two of five individuals will be diagnosed with cancer in their lifetime and one in four will die from this disease. Given the disparities observed in health research among Black individuals, we conducted a scoping review to analyze the state of cancer research in Canadian Black communities regarding prevalence, incidence, screening, mortality, and related factors to observe advances and identify gaps and disparities. METHODS A comprehensive search strategy was developed and executed in December 2021 across 10 databases (e.g., Embase). Of 3451 studies generated by the search, 19 were retained for extraction and included in this study. RESULTS Studies were focused on a variety of cancer types among Black individuals including anal, breast, cervical, colorectal, gastric, lung, and prostate cancers. They included data on incidence, stage of cancer at diagnosis, type of care received, diagnostic interval length, and screening. A few studies also demonstrated racial disparities among Black individuals. This research reveals disparities in screening, incidence, and quality of care among Black individuals in Canada. CONCLUSIONS Given the gaps observed in cancer studies among Black individuals, federal and provincial governments and universities should consider creating special funds to generate research on this important health issue. PLAIN LANGUAGE SUMMARY Important gaps were observed on research on cancer among Black communities in Canada. Studies included in the scoping review highlights disparities in screening, incidence, and quality of care among Black individuals in Canada.

Abstract
IMPORTANCE As stated in the DSM-5, it is generally reported that the prevalence of attention-deficit/hyperactivity disorder (ADHD) is lower among Black individuals compared with the general population. However, Black individuals living in countries where they are considered a minority population group (eg, in Northern America and Europe) are underrepresented in studies evaluating ADHD. OBJECTIVE To estimate the pooled prevalence of ADHD and identify associated risk factors among US Black individuals. DATA SOURCES This systematic review and meta-analysis identified peer-reviewed studies published until October 18, 2019, using the APA PsycInfo, MEDLINE, Embase, Cochrane CENTRAL, CINAHL, ERIC, and Education Source databases. STUDY SELECTION Eligible trials were published in French or English, had empirical data on the prevalence of ADHD in samples or subsamples of Black people, and were conducted in countries with Black minority populations. All studies were assessed and passed quality evaluation. DATA EXTRACTION AND SYNTHESIS The PRISMA guideline was used for extracting and reporting data. Random-effects meta-analyses were generated to estimate the prevalence of ADHD among Black individuals using the metafor package in R. MAIN OUTCOMES AND MEASURES Prevalence and risk factors associated with ADHD among Black individuals were identified. RESULTS A total of 24 independent samples and subsamples from 21 studies published between 1979 and 2020 (154 818 Black participants) were included in this systematic review and meta-analysis. All included studies were conducted in the US. Two studies were conducted assessing adults (aged 18 years or older), 8 assessing children (0-12 years), 1 assessing adolescents (aged 13-17 years), and 13 assessing both children and adolescents. The pooled prevalence of ADHD was 14.54% (95% CI, 10.64%-19.56%). In a narrative review of the studies in this analysis, some studies found risk factors associated with ADHD, such as sociodemographic characteristics (age, sex, race, and socioeconomic status), familial factors, environmental factors, and risk behaviors, but the data did not permit a moderation analysis to assess these findings in this study. CONCLUSIONS AND RELEVANCE Contrary to what is stated in the DSM-5, the results of this systematic review and meta-analysis suggest that Black individuals are at higher risk for ADHD diagnoses than the general US population. These results highlight a need to increase ADHD assessment and monitoring among Black individuals from different social backgrounds. They also higlight the importance of establishing accurate diagnoses and culturally appropriate care.

Abstract
INTRODUCTION Black British communities are disproportionately burdened by type 2 diabetes (T2D) and its complications. Tackling these inequalities is a priority for healthcare providers and patients. Culturally tailored diabetes education provides long-term benefits superior to standard care, but to date, such programmes have only been developed in the USA. The current programme of research aims to develop the Healthy Eating and Active Lifestyles for Diabetes (HEAL-D) culturally tailored T2D self-management programme for black British communities and to evaluate its delivery, acceptability and the feasibility of conducting a future effectiveness trial of HEAL-D. METHODS AND ANALYSIS Informed by Medical Research Council Complex Interventions guidance, this research will rigorously develop and evaluate the implementation of the HEAL-D intervention to understand the feasibility of conducting a full-scale effectiveness trial. In phase 1, the intervention will be developed. The intervention curriculum will be based on existing evidence-based T2D guidelines for diet and lifestyle management; codesign methods will be used to foster community engagement, identify the intervention's underpinning theory, identify the optimal structure, format and delivery methods, ascertain adaptations that are needed to ensure cultural sensitivity and understand issues of implementation. In phase 2, the intervention will be delivered and compared with usual care in a feasibility trial. Process evaluation methods will evaluate the delivery and acceptability of HEAL-D. The effect size of potential primary outcomes, such as HbA1c and body weight, will be estimated. The feasibility of conducting a future effectiveness trial will also be evaluated, particularly feasibility of randomisation, recruitment, retention and contamination. ETHICS AND DISSEMINATION This study is funded by a National Institute of Health Research Fellowship (CDF-2015-08-006) and approved by National Health Service Research Ethics Committee (17-LO-1954). Dissemination will be through national and international conferences, peer-reviewed publications and local and national clinical diabetes networks. TRIAL REGISTRATION NUMBER NCT03531177; Pre-results.

Abstract
Cardiovascular disease is the leading cause of mortality in the United States, accounting for one fourth of deaths. Higher rates of obesity put Hispanic and Black men at increased risk. The American Heart Association cites diet quality, physical activity, and body weight as alterations responsive to health promotion intervention. Prevention strategies need to begin in adolescence and the emerging adulthood years to impact cumulative risk factors. A scoping review identified search terms and this was followed by a systematic review of Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PubMed databases for articles published in English from January 1, 2002, through May 11, 2017. This review explores community-based content, delivery, recruitment, or retention strategies used with young men of color aged 15 to 24 years. Of 17 articles describing 16 individual interventions and 1 describing multiple interventions (with samples ranging from 37 to 4,800), 13 reported significant results in one or more domains. No studies specifically targeted the needs of young men and only three had more than 50% male participants. There was a gap in studies that addressed young men in the ages of interest with most interventions reaching participants aged 11 to 19 years. Cultural tailoring was addressed through recruitment setting, interventionist characteristics, community involvement, and theoretical frameworks such as motivational interviewing that allow individual goal setting. Because young men seek access to preventive health services less than young women, it is suggested that interventions that are community based or use push technology (send information directly to the user) be increased.

Abstract
Young adults are underrepresented in standard behavioral weight loss trials, and evidence suggests that they differ from older adults on many weight-related constructs. The aim of this review is to explore young adults' attitudes toward obesity and weight management, with particular attention to those factors that may play a role in the development of future treatment efforts. Both intrapersonal and interpersonal considerations unique to young adulthood are assessed; in addition, we examine young adults' perceptions of specific weight-related behaviors such as dieting, physical activity, and self-weighing. Conclusions are consistent with other findings suggesting that weight management interventions should be adapted and designed specifically for this age group.

Abstract
African American females are adversely affected by overweight and obesity and accompanying physical, psychosocial, and economic consequences. Behavioral weight management interventions are less effective in addressing the needs of overweight and obese African American females. The objective of this scoping review was to explore weight management research in this population to identify key concepts, gaps in the literature, and implications for future research. Analyses revealed a broad array in purpose, theoretical frameworks, settings, study designs, interventions, intervention strategies, and outcome variables, making comparison difficult. Many of the articles included in this review did not provide a rich description of methods, which hinder their use in the development of future studies. Consistent application of a combined theory may address the gaps identified in this review by providing a reliable method for assessing needs, developing interventions, and evaluating the effectiveness and fidelity of behavioral weight management interventions in overweight and obese African American females.

Abstract
BACKGROUND African-Americans lose less weight during a behavioral intervention compared with Whites, which may be from differences in dietary intake or physical activity. METHODS Subjects (30% African American, 70% White; n = 346; 42.4 ± 9.0 yrs.; BMI = 33.0 ± 3.7 kg/m2) in an 18-month weight loss intervention were randomized to a standard behavioral (SBWI) or a stepped-care (STEP) intervention. Weight, dietary intake, self-report and objective physical activity, and fitness were assessed at 0, 6, 12, and 18 months. RESULTS Weight loss at 18 months was greater in Whites (-8.74 kg with 95% CI [-10.10, -7.35]) compared with African Americans (-5.62 kg with 95% CI [-7.86, -3.37]) (P = .03) in the SBWI group and the STEP group (White: -7.48 kg with 95% CI [-8.80, -6.17] vs. African American: -4.41kg with 95% CI [-6.41, -2.42]) (P = .01). Patterns of change in dietary intake were not different between groups. Objective physical activity (PA) changed over time (P < .0001) and was higher in Whites when compared with African Americans (P = .01). CONCLUSIONS Whites lost more weight (3.10 kg) than African American adults. Although there were no differences in dietary intake, Whites had higher levels of objective PA and fitness. Thus, the discrepancy in weight loss may be due to differences in PA rather than dietary intake. However, the precise role of these factors warrants further investigation.

Abstract
BACKGROUND The high prevalence of obesity in African American (AA) women may result, in part, from a lower resting metabolic rate (RMR) than non-AA women. If true, AA women should require fewer calories than non-AA women to maintain weight. Our objective was to determine in the setting of a controlled feeding study, if AA women required fewer calories than non-AA women to maintain weight. MATERIALS AND METHODS This analysis includes 206 women (73% AA), aged 22-75 years, who participated in the Dietary Approaches to Stop Hypertension (DASH) trial-a multicenter, randomized, controlled, feeding study comparing the effects of 3 dietary patterns on blood pressure in individuals with prehypertension or stage 1 hypertension. After a 3-week run-in, participants were randomized to 1 of 3 dietary patterns for 8 weeks. Calorie intake was adjusted during feeding to maintain stable weight. The primary outcome of this analysis was average daily calorie (kcal) intake during feeding. RESULTS AA women had higher baseline weight and body mass index than non-AA women (78.4 vs 72.4 kg, P < .01; 29.0 vs 27.6 kg/m(2), P < .05, respectively). During intervention feeding, mean (SD) kcal was 2168 (293) in AA women and 2073 (284) in non-AA women. Mean intake was 94.7 kcal higher in AA women than in non-AA women (P < .05). After adjustment for potential confounders, there was no difference in caloric intake between AA and non-AA women (Δ = -2.8 kcal, P = .95). CONCLUSION These results do not support the view that AA women are at greater risk for obesity because they require fewer calories to maintain weight.
