Diet and Physical Activity Interventions for People from Minority Ethnic Backgrounds in the UK: A Scoping Review Exploring Barriers, Enablers and Cultural Adaptations.

BACKGROUND: Type 2 diabetes (T2D) and cardiovascular disease (CVD) are a global pandemic, driven by obesity, poor diet and physical inactivity. In the UK, the prevalence of T2D and CVD is higher in minority ethnic groups. Lifestyle prevention interventions can be effective but uptake amongst minority ethnic groups in the UK is low and the extent of cultural adaptations to increase engagement unknown. AIM: To explore barriers, enablers and culturally adapted lifestyle interventions in UK minority ethnic groups. METHODS: Four electronic databases were searched from to January 2013-2023. Two independent reviewers carried out manuscript selection and data extraction. Barriers and enablers were mapped to the Capability + Opportunity + Motivation = Behaviour (COM-B) theoretical model. Intervention adaptations were linked to behaviour change strategies and reported within a Cultural Adaptation framework. RESULTS: Twenty-three studies were included, reporting barriers/enablers, culturally adapted interventions or both. Barriers and enablers mostly mapped to social and physical opportunity, and reflective motivation. Common adaptation strategies considered behavioural influences related to culture, values, religious beliefs and/or traditions. Most impactful strategies were associated with using credible sources of information and reorganising social and environmental contexts. DISCUSSION AND CONCLUSIONS: The current umbrella approach to preventative intervention delivery is unlikely to promote sustained participation in behaviour change amongst UK ethnic minorities. Engagement strategies for this population should consider key determinants such as social contexts, beliefs and cultural norms. Important research gaps include interventions investigating tailored interventions for Black populations, and the impact of negative social experiences (e.g., racism) on engagement.

Association between obesity phenotypes and dietary patterns: A two-step cluster analysis based on the China multi-ethnic cohort study.

OBJECTIVE: This study aimed to explore obesity phenotypes and investigate their association with dietary patterns. METHODS: Data were obtained from the baseline survey conducted in the China Multi-Ethnic Cohort Study from July 2018 to August 2019. All participants with a body mass index of at least 24 kg/m2 were enrolled and underwent a questionnaire survey, physical examination, and clinical laboratory tests. A two-step cluster analysis was employed to classify the participants into phenotypes. Dietary information was collected using the food frequency questionnaire, and principal component analysis was conducted to identify distinct dietary patterns. RESULTS: We analyzed the data of 8757 participants. They were categorized based on demographic characteristics, biochemical indicators, and anthropometric measurements into two distinct clusters identified as metabolically healthy obesity and metabolically unhealthy obesity (MUO). Key predictors included serum uric acid, sex, and diastolic blood pressure. Subgroup analysis by sex identified three distinct clusters within both male and female participants. The MUO group had the highest prevalence of a range of chronic noncommunicable diseases. The analysis uncovered three unique dietary patterns among participants classified as the premium protein, rice-oil-red meat, and oil-salt patterns. Notably, the MUO subgroup demonstrated significantly higher factor scores for both the rice-oil-red meat and oil-salt patterns. CONCLUSIONS: Obesity phenotypes are closely related to metabolic and demographic characteristics, with serum uric acid being a significant factor in categorizing the metabolic states of obesity. The rice-oil-red meat and oil-salt patterns may be related to the metabolic status of individuals with obesity.

Diabetes Distress and Associated Factors Among Chinese Americans with Type 2 Diabetes in New York City.

Purpose: The purpose of this study is to describe diabetes distress and related factors among Chinese Americans with type 2 diabetes in New York City (NYC). Methods: We conducted a secondary data analysis of the baseline data from three research studies conducted among community-dwelling Chinese American adults with type 2 diabetes. Diabetes Distress Scale (DDS) was used to measure sources of diabetes distress including emotional-, regimen-, interpersonal-, and physician-related distress. A score of 2 or greater indicates moderate diabetes distress or higher. Patient Health Questionnaire-2 (PHQ-2) was used to measure depressive symptoms. Participants' sociodemographic information was also collected. Descriptive statistics were used to describe diabetes distress, and logistic least absolute shrinkage and selection operator (LASSO) regression was used to examine factors associated with diabetes distress level. Results: Data from 178 participants (mean age 63.55±13.56 years) were analyzed. Most participants were married (76.40%), had a high school degree or less (65.73%), had a household annual income < $25,000 (70.25%), and reported limited English proficiency (93.22%). About 25.84% reported moderate or higher overall distress. The most common sources of distress were emotional burden (29.78%), followed by regimen- (28.65%), interpersonal- (18.54%), and physician-related distress (14.04%). Participants who were younger, female, limited English proficient, and had elevated depressive symptoms were more likely to have higher diabetes distress. Conclusion: Diabetes distress is prevalent among Chinese immigrants with type 2 diabetes, especially emotional- and regimen-related distress. Given the known link between diabetes distress and poor glycemic control, it is critical to screen for diabetes distress at primary care clinics and incorporate psychological counseling in diabetes care in this underserved population.

Health lifestyles of six Zhiguo ethnic groups in China: a latent class analysis.

BACKGROUND: Zhiguo ethnic groups, commonly known as "the directly-entering-socialism ethnic groups", represent Chinese ethnic minorities who have undergone a unique social development trajectory by transforming directly from primitive societies to the socialist stage. In recent decades, significant lifestyle transformations have occurred among Zhiguo ethnic groups. Understanding their health lifestyles can play a strategic role in China's pursuit of universal health coverage. This study aims to examine patterns of health-related lifestyle among Zhiguo ethnic groups and explore whether sociodemographic features and specific indicators related to health status are associated with particular classes. METHODS: A cross-sectional study was conducted in Yunnan Province, China, from July to December 2022. Stratified random sampling method was employed to recruit residents belonging to six Zhiguo ethnic groups aged between 15 and 64. Latent class analysis was performed to identify clusters of health-related behaviors within each ethnic group. Logistic regression was utilized to determine the predictors of health lifestyles. RESULTS: A total of 1,588 individuals from the Zhiguo ethnic groups participated in this study. Three latent classes representing prevalent health lifestyles among the Zhiguo ethnic groups were identified: "unhealthy lifestyle" (31.80%), "mixed lifestyle" (57.37%), and "healthy lifestyle" (10.83%). In the overall population, individuals belonging to the "healthy lifestyle" group exhibited a higher likelihood of being non-farmers (OR: 2.300, 95% CI: 1.347-3.927), women (OR: 21.459, 95% CI: 13.678-33.667), married individuals (OR: 1.897, 95% CI: 1.146-3.138), and those residing within a walking distance of less than 15 min from the nearest health facility (OR: 2.133, 95% CI: 1.415-3.215). Conversely, individuals in the age cohorts of 30-39 years (OR: 0.277, 95% CI: 0.137-0.558) and 40-49 years (OR: 0.471, 95% CI: 0.232-0.958) showed a decreased likelihood of adopting a healthy lifestyle. CONCLUSIONS: A considerable proportion of the Zhiguo ethnic groups have not adopted healthy lifestyles. Targeted interventions aimed at improving health outcomes within these communities should prioritize addressing the clustering of unfavorable health behaviors, with particular emphasis on single male farmers aged 30-49, and expanding healthcare coverage for individuals residing more than 15 min away from accessible facilities.

Risk Factors Associated With General and Abdominal Obesity Among South Asian Minorities in Hong Kong.

South Asians have become a sizable ethnic minority in Hong Kong with unique health and social needs often being overlooked. Elevated obesity risk among South Asians has been highlighted in high-income Western settings; however, relevant local evidence is scarce. This cross-sectional study aims to explore the obesity prevalence and related risk factors among South Asians in Hong Kong. Between June 2022 and February 2023, 535 South Asian adults were recruited via territory-wide health outreach services, and completed a survey and anthropometric measurements on height, weight, and waist circumference. In our female-dominated sample (84.1% female; mean age = 41.0 ± 12.3 years), the observed prevalence of general obesity (body mass index [BMI] ≥ 27.5 kg/m2 for South Asians) and abdominal obesity (waist-to-height ratio [WHtR] > 50%) were 60.2% and 89.4%, respectively. Results from multivariable linear regressions showed that mean BMI and WHtR were significantly higher among women and Pakistani individuals (and Nepalese individuals for BMI only) but lower among better educated and employed respondents. Apart from age, household size, and marital status as common risk factors, having a healthier diet and higher physical activity level were also associated with lower WHtR. Notably, the associations of female gender and Pakistani ethnicity were attenuated after adjustments for socioeconomic and lifestyle factors. In conclusion, there was a high prevalence of obesity in South Asian participants in this study. The identified risk and protective factors could inform targeted services and community-based weight management programs to mitigate obesity and its associated cardiometabolic risks in this fast-growing but vulnerable community.

Gender differences in COVID-19-related behaviours: evidence from three ethnic minority groups.

BACKGROUND: The SARS-CoV-2 pandemic has hit minorities more profoundly than the majority society. We evaluated the interplay between ethnic minority identity, gender, and COVID-19-related attitudes and behaviours. PARTICIPANTS AND PROCEDURE: Using data from a survey carried out among both members of ethnic minorities in Poland and Mexico and the majority outgroups, we assessed the perception of the pandemic as a grave threat to the self and to the world, as well as compliance with the protective measures to stop the spread of COVID-19. We tested the effects of gender and minority versus majority status on protective compliance, and of the pandemic as a threat to the self and the world. RESULTS: A two-way ANOVA test with gender and ethnicity factors revealed significant effects of gender, ethnicity, and gender × ethnicity interaction. The effect of gender was significant for compliance with protective behaviours, threat to the self, and threat to the world. Women had higher mean levels of protective behaviours, perceptions of threat to the self, and perceptions of threat to the world than men. The effect of Indigenous ethnicity was significant for protective behaviours and threat to the world. The mean level of protective behaviours and threat to the world was higher for ethnic minority groups than for non-minority groups. CONCLUSIONS: Maladaptive gender differences in COVID-19-related attitudes and behaviour are less prominent among people self-identifying as ethnic minority members.

Correlates and Health Issues among Older Korean Immigrants Living Alone in the United States: A Scoping Review.

Older Korean immigrants are one of the most understudied and marginalized Asian ethnic groups in the United States, despite their rapid population growth. Many older Korean immigrants encounter distinct challenges in assimilating into their new country as first-generation immigrants, including cultural conflict, language barriers, low economic status, and a lack of social support. These issues may be compounded for those who live alone, which is considered a negative factor in their mental and physical health. However, little is known about the correlates and health issues of older Korean immigrants living alone. This study's objective was to explore correlates and health issues among older Korean immigrants living alone. Based on established scoping review methodology five databases, CINAHL, PubMed, MEDLINE, SocINDEX, and Health Source Nursing/Academic Edition, were used to find relevant studies. Twelve articles were reviewed, and four major themes were identified as correlates and health issues among older Korean immigrants living alone in the United States: depression, changed family relationships, social interactions, and factors on general health and well-being. The findings have significant implications for healthcare professionals for understanding the unique culture, situation, and physical and psychosocial vulnerability of older Korean immigrants living alone.

Ethnic socialisation profiles and depression among ethnic minority adolescents in China: a person-centred approach.

BACKGROUND: Ethnic socialisation plays a vital role in the development of ethnic minority adolescents. However, the generalizability of research findings beyond the context of immigrant societies in the United States remains unclear. METHODS: Utilising a person-centred approach, this study analysed a sample of 2,600 ethnic minority adolescents in China (55.8% female, Mage = 14.93 ± 1.82) to explore ethnic socialisation patterns, and their correlations with depression. RESULTS: Latent profile analysis revealed four distinct ethnic socialisation profiles: low-frequency, moderate-frequency, high-frequency and proactive integration orientation. Adolescents with the high-frequency profile displayed the highest levels of depression, followed by those with the moderate-frequency profile, whereas adolescents with the low-frequency and proactive integration orientation profiles showed a lower risk of depression. CONCLUSIONS: Within the sociocultural context of China, ethnic minority families' ethnic socialisation practices demonstrate unique characteristics. Various ethnic socialisation messages are integrated in diverse patterns to exert influence on adolescents.

Improving Pathways to Care for Ethnic Minority Communities.

It is well established that the COVID-19 pandemic has had a substantial impact on ethnic minority communities and has worsened existing health inequalities experienced by these populations globally. Individuals from ethnic minority backgrounds have not only been more likely to become infected with COVID-19 throughout the pandemic, but they have also higher risk of adverse symptoms and death following infection. Factors responsible for these discrepancies are wide reaching and encompass all aspects of the social determinants of health (SDoH). Although always an area of concern among healthcare professionals, barriers to health care experienced by ethnic minority populations became a more pertinent issue during the COVID-19 pandemic when all individuals required sufficient and sustained access to a healthcare system (whether this be for COVID-19 testing, vaccination or treatment). These healthcare barriers exacerbated the increased COVID-19 burden experienced by minority populations and will continue to detrimentally impact the health of these populations during future COVID-19 waves or indeed, future novel pandemics. This chapter aims to summarise the major healthcare barriers experienced by minority populations throughout the COVID-19 pandemic, including COVID-19 prevention, vaccine rollout, care during hospitalisation and post-COVID care for long COVID patients. To end, this chapter will summarise lessons learned and future directions that need to be taken to improve health disparities and healthcare access for minority populations in relation to the COVID pandemic and beyond.

Better perceived health among the Swedish-speaking minority as compared with the Finnish-speaking majority in Finland: a cross-sectional study with an intergenerational perspective.

BACKGROUND: Previous research has shown that the Swedish speaking minority in Finland has slightly but significantly better health compared with the Finnish speaking majority. However, a clear explanation for this is lacking. AIM: The aim of the study was to explore differences of perceived health comparing three groups: Swedish speakers with reported dominance of Swedish also in the preceding generation; contemporary Finnish speakers with reported dominance of Finnish in the preceding generation and a group with a reported mixed-language structure of Finnish and Swedish between generations. INDIVIDUALS AND METHODS: Health and Social Support is an on-going population-based survey initiated in 1998 (N = 64,797), aimed at working-age adults. The present study is based on the 2012 follow-up survey, which included a question on the dominating language (Swedish or Finnish) of the respondents and their parents. The outcome was perceived health, which in this study was dichotomized to very good/good and intermediate/poor/very poor. The statistical analysis was carried with logistic regression, using SAS software. Age, gender and occupational training were included as covariates in the multivariable analysis. RESULTS: This study found that the Swedish-speaking group in Finland report better perceived health compared with the Finnish-speaking group (odds ratio 1.28, 95% confidence interval 1.04-1.57, p < 0.001). The health of the mixed language-speaking group fell between the other two groups. CONCLUSIONS: The results gave some support to a culturally mediated mechanism for the health advantage of Swedish speakers. Cultural features of Swedish-speaking groups in Finland may also support health promotion of the Finnish-speaking majority.

Enhancing community engagement, public involvement, and social capital through researchers' participation in community dance projects: unexpected outcomes in underserved communities.

BACKGROUND: The Dance and Health project aimed to promote public involvement in health research. Public involvement leads worked with project partner community groups, Aakash Odedra Dance Company and Moving Together, to develop a community engagement project with people living in low-socioeconomic areas/deprivation and diverse ethnic minority groups. Dance and Health included a weekly 60-min dance class and 30 min of facilitated health science discussion, that could either be a public involvement discussion for a research project, an activity about a particular biomedical research theme or ongoing discussions with a visiting researcher. The goal of this paper is to explore the impact of the Dance and Health project on the social capital of participants and provide key learnings on how to engage and build partnerships with people from underserved groups in health research contexts. METHODS: Qualitative interviews and focus groups were completed which explored participant and dance tutor experiences in community venues. Participants were aged between 22 and 90, most were female and were from Asian ethnic minority groups and White British groups living in deprived neighbourhoods in Leicester. Qualitative data were analysed using qualitative content analysis. RESULTS: The responses to the Dance and Health project were positive across all the focus groups. Central themes identified were Feedback on the Project, Motivation to Exercise, Criticism of the NHS, Mental Wellbeing, Engagement in a Post Pandemic New Normal, Accessibility and Inclusivity, Empowerment and Building Social Capital. DISCUSSION: The focus groups evidenced that the project had broad impact. Participants expressed empowerment and ownership and described a range of social capital enrichment generated through the project including networks and friendships, access to the institutional resource of health science, and the opportunity to engage with a health and leisure activity that was valued and meaningful.

A research team worked with community dance schools in Leicester to try to get more people from the Asian community and from poorer neighbourhoods involved in research and science. By taking part in the project, people benefitted from an opportunity to exercise and to learn about and influence health research taking place locally. However, the researchers also noticed that there were other benefits to the project. Dancing and learning about health science helped people bond and form new friendships. The researchers joined in, and this helped build friendships and trust between participants and people working in science and research. This is called bridging which is where we bring people together from different groups. The dance sessions made the researchers more approachable and less intimidating, so it was easier to trust them and build friendships. Bridging and bonding are ways of building social capital. Social capital describes the social resources that people can access in their neighbourhoods and communities e.g. facilities (village halls or clubs) and support networks. Researchers delivered focus groups in which participants talked about Feedback on the Project, Motivation to Exercise, Criticism of the NHS, Mental Wellbeing, Engagement in a Post Pandemic New Normal, Accessibility and Inclusivity, Empowerment and Social Capital. This supported the idea that projects where we try to engage with communities can build social capital. This is most likely when projects provide safety and accessibility, (1) and flexibility, a sense of belonging, commitment, communication, being genuine, relevance, sustainability (4).

The underrepresentation of racial/ethnic minorities in research on co-use of nicotine, alcohol, and/or cannabis via ecological momentary assessment methods: A narrative review.

BACKGROUND: Co-use of nicotine, alcohol and/or cannabis is common among adults in the United States. Co-use may represent greater addiction severity than single substance use. Recent studies have examined the extent to which the frequency, order, simultaneity, motivations, and contextual factors associated with co-use differ from that of single use. Co-use has become prevalent among racial/ethnic minority individuals who exhibit distinct co-use patterns and related outcomes; however, most of these studies rely on cross-sectional or sparse longitudinal observations. Ecological momentary assessment (EMA) can illuminate such patterns and associations with time-varying contexts. This review summarizes EMA studies on co-use published from 2008 to 2023 involving racial/ethnic minority individuals and point to gaps. Our review addresses: 1) whether use of one substance leads to substitution or complementary use of another, 2) whether antecedents/contexts differ by co-use patterns and minority status, and 3) what consequences of co-use have been documented across co-use patterns or minority status. METHODS: Search results yielded 465 articles, with 33 meeting inclusion criteria. We extracted study-level characteristics and synthesized the findings. RESULTS: The findings largely focused on co-use patterns, categories of co-use, proximal antecedents and contexts, and consequences. Variations by minority status were rarely examined; few examined acute effects of unique experiences that may contribute to co-use among racial/ethnic minority adults. CONCLUSIONS: The EMA literature on co-use is burgeoning in recent years and supports complementary hypothesis. More research to capture time-intensive data on experiences to contextualize the co-use among racial/ethnic minority groups with greater diversity in race/ethnicity is warranted.

The Role of Contextual Variables and Structural Diversity on College Students' Engineering Self-Efficacy.

Structural diversity is defined as the numerical representation of diverse racial/ethnic student groups on campus as one way of exposing students to diversity in higher education. The current study implemented the concept of structural diversity on faculty in higher education, given the significant and unique roles in STEM education. We integrated the proportion of URM faculty within the College of Engineering as a moderating variable in the social cognitive career theory (SCCT) model. With a sample of 254 diverse engineering students from six universities, the results indicated that both perceived engineering barriers and perceived engineering supports significantly related to perceived self-efficacy even after controlling for the effects of the other. Perceived engineering supports mediated the effects of engineering barriers on self-efficacy. Moreover, a moderated mediation effect by the proportion of URM faculty was observed, showing that when the proportion of URM faculty reached a certain level, high levels of perceived engineering barriers had no effect on increasing perceived engineering supports. Implications for fostering career development in engineering with a systematic-tailored approach are discussed.

Social Determinants of Health and Biological Age among Diverse U.S. Adults, NHANES 2011-2018.

We examined the sex-specific association between education and income with biological age (BA) and by race/ethnicity. The Klemera-Doubal method was used to calculate BA among 6,213 females and 5,938 males aged 30-75 years who were Hispanic, non-Hispanic (NH) White, NH Black (NHB), or NH Asian (NHA). Compared with a college education, less than a high school education was associated with greater BA by 3.06 years (95% CI: 1.58, 4.54) among females only; associations were strongest among NHB, Hispanic, and NHA females. Compared with an annual income of ≥$75,000, an income <$25,000 was associated with greater BA by 4.95 years (95% CI: 3.42, 6.48) among males and 2.76 years among females (95% CI: 1.51, 4.01); associations were strongest among NHW and NHA adults, and Hispanic males. Targeting upstream sources of structural disadvantage among racial/ethnic minority groups, in conjunction with improvements in income and education, may promote healthy aging in these populations.

Knowledge, attitudes and practices toward cervical cancer screening among ethnic minorities in inner Mongolia, China.

AIMS: This study aimed to assess the knowledge, attitudes and practices (KAP) towards cervical cancer screening among ethnic minorities in Inner Mongolia, China. METHODS: A cross-sectional study was conducted in Inner Mongolia between May and September, 2023, and recruiting participants undergoing dual-cancer screening. Demographic characteristics and KAP status were assessed using a self-administered questionnaire. RESULTS: A total of 533 valid questionnaires were collected, with 53.66% aged 40 years or younger. Mean scores for knowledge, attitude, and practice were 13.58 ± 5.41, 41.06 ± 4.53, and 13.35 ± 1.53, respectively. Positive associations were found between knowledge and attitude (r = 0.348, p < 0.001), knowledge and practice (r = 0.288, p < 0.001), and attitude and practice (r = 0.817, p < 0.001). Structural equation modelling confirmed direct positive associations between knowledge and attitude (path coefficient = 0.307, p < 0.001) and attitude and practice (path coefficient = 0.270, p < 0.001). Additionally, knowledge demonstrated an indirectly positive association with practice (path coefficient = 0.083, p = 0.007). CONCLUSION: Ethnic minorities in Inner Mongolia exhibit insufficient knowledge, positive attitudes, and proactive practices toward cervical cancer screening. Implementing targeted educational initiatives is crucial to enhance their KAP.

Identifying the intersection of parental HPV and COVID-19 vaccine hesitancy to inform health messaging interventions in community-based settings.

PURPOSE: Parental human papillomavirus (HPV) vaccine hesitancy contributes to delays or refusals in adolescent uptake. It is unclear if COVID-19 vaccine hesitancy has further impacted the low HPV vaccine uptake trends among underrepresented minorities. This study examines the relationship between COVID-19 vaccine intent and HPV vaccine hesitancy among parents for their adolescents in communities with low vaccine uptake in Los Angeles County. METHODS: Parents from a school-based academic enrichment program serving low-income, first-generation immigrant families completed an online cross-sectional survey to understand parental HPV vaccine hesitancy, adolescent HPV vaccine behavior, and attitudes towards other vaccines, including intent to receive COVID-19 vaccines. In March 2021, parents with children ages 9-17 years completed online surveys. Using multivariate logistic regression models, we examined whether low parent intent to vaccinate their adolescent against COVID-19 was associated with hesitancy to vaccinate against HPV. RESULTS: A total of 291 surveys were completed. Among parents with high HPV vaccine hesitancy for their adolescent, 33 % did not intend to vaccinate their adolescent against COVID-19 compared to 7 % among parents with low HPV vaccine hesitancy. Low parent intention to vaccinate adolescent against COVID-19 was associated with higher HPV vaccine hesitancy (p < 0.01) after controlling for parent nativity status, medical mistrust, receiving the flu vaccination and negative HPV information. DISCUSSION: Our findings indicate associations between low parental COVID-19 vaccine intent and higher HPV vaccine hesitancy for their adolescent. Identifying community-relevant health interventions to address parental vaccine hesitancy across multiple child and adolescent vaccines may help to achieve equitable vaccine uptake.

Latent heterogeneity of deviant behaviors and associated factors among ethnic minority adolescents: a latent class analysis.

BACKGROUND: Deviant behaviors are common during adolescence. Despite the diversity of juvenile delinquency, the patterns of deviant behaviors remain unclear in ethnic minorities. The present study aimed to evaluate the latent heterogeneity of deviant behaviors and associated factors in ethnic minority Yi adolescents. METHODS: The present study recruited a large sample of 1931 ethnic minority Yi adolescents (53.4% females, mean age = 14.7 years, SD 1.10) in five secondary schools in 2022 in Sichuan, China. The participants completed measures on 13 deviant behaviors and demographic characteristics, attitudinal self-control, and psychological distress. Sample heterogeneity of deviant behaviors was analyzed via latent class analysis using class as the cluster variable. RESULTS: The data supported three latent classes with measurement invariance by sex. 68.2%, 28.0%, and 3.8% of the sample were in the Normative, Borderline, and Deviant class, with minimal, occasional, and extensive deviant behaviors, respectively. The Deviant class was more prevalent in males (6.5%) than females (1.6%). There were significant class differences in domestic violence, school belonging, self-control, anxiety, and depressive symptoms. Males, domestic violence, low school belonging, and impaired self-control significantly predicted higher odds of the Deviant and Borderline classes compared to the normative class. CONCLUSION: This study provided the first results on three latent classes of deviant behaviors with distinct profiles in ethnic minority adolescents in rural China. These results have practical implications to formulate targeted interventions to improve the psycho-behavioral functioning of the at-risk adolescents in ethnic minorities.

The Longitudinal Relationship Between Diet Quality and Executive Functioning Development of Hispanic Preschoolers in Houston, Texas.

BACKGROUND: Diet quality has been found to be related to cognitive health in school-aged children. However, this relationship remains understudied among Hispanic preschool-aged children, who are vulnerable to poor dietary habits and low cognitive development due to socioeconomic, cultural, and structural disparities. OBJECTIVE: This longitudinal study evaluated whether the diet quality of preschool-aged children would be associated with executive functions (EFs) in later childhood. DESIGN: This is a secondary analysis of a longitudinal study of Hispanic preschool-aged children (age 4 and 5 years) at baseline (Time 1) and 18 months (Time 2). PARTICIPANTS AND SETTING: This study included 185 mother-child dyads with complete data at Time 1, recruited through Head Start centers in Houston, TX, beginning in 2011. MAIN OUTCOME MEASURES: Mothers reported on their child's dietary intake via 3 24-hour recalls, which was used to calculate Healthy Eating Index (HEI)-2010 component and total scores. Laboratory tasks assessed cold EFs (tapping and Flexible Item Selection Tasks) and hot EFs (delay of gratification and gift-wrapping tasks). Whereas higher scores on tapping, Flexible Item Selection Task, and delay of gratification tasks represent a high EF, higher scores in gift-wrapping task represent a low EF. STATISTICAL ANALYSES PERFORMED: Hierarchical linear regression analyses assessed the relationship between diet quality, as measured by HEI-2010 total and component scores, at Time 1 (independent variables) and EF outcomes (dependent variables) at Time 2, controlling for child sex, age, body mass index z score, and EF at Time 1. RESULTS: HEI-2010 component score for fatty acids (b = -.13; P = .04) and seafood and plant proteins (b = .09; P = .05), were respectively related to later cold and hot EFs of Hispanic preschool-aged children. Other HEI components or the overall score did not predict EFs. CONCLUSIONS: This study shows that specific HEI components support cold and hot EFs development among Hispanic preschool-aged children, but total HEI-2010 score does not. Experimental research is needed to assess the influence of dietary interventions on cognitive development of Hispanic preschool-aged children.

Axillary Reverse Mapping Aids in Reducing the Rates of Breast Cancer-Related Lymphedema in Underserved Ethnically Diverse Population.

BACKGROUND: Breast cancer-related lymphedema (BCRL) poses a significant risk following sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND), particularly affecting ethnic minorities, with a twofold increased risk. Axillary reverse mapping (ARM), a novel technique, shows potential in reducing BCRL rates, yet its utility in ethnic minorities lacks sufficient exploration. Therefore, our study aims to investigate the utility and outcomes of ARM on BCRL in an ethnic diverse group. METHODS: A retrospective chart review of ARM patients from January 2019 to July 2022 was conducted, monitoring patients over 24 months at 3-month intervals using SOZO® scores, with comparisons with preoperative baselines. RESULTS: Of the 212 patients, 83% belonged to ethnic minorities. SLNB was performed in 83%, ALND in 17%, and 62.3% underwent radiation therapy. Positive lymph nodes were found in 31.6%, with 22.2% exhibiting blue nodes and 25.9% exhibiting blue lymphatics. Of identified blue nodes, 70.2% were excised, including 51.5% crossover nodes. Lymphedema occurred in 3 patients, resulting in a BCRL rate of 1.4%. Compared with an historical BCRL incidence of 40.4% following ALND in ethnic minorities, our study reported a significantly lower rate of 8% (p < 0.001). CONCLUSION: The ARM procedure can significantly lower BCRL in ethnic minority groups. The combination of ARM and bioimpedance spectroscopy led to a remarkably low BCRL rate of 1.4%. Notably, none of the patients in our study developed an axillary recurrence at 24-month follow-up. Nevertheless, future studies with larger sample sizes are warranted to better understand the utility of the ARM technique in this population.

A comprehensive whole genome database of ethnic minority populations.

China, is characterized by its remarkable ethnical diversity, which necessitates whole genome variation data from multiple populations as crucial tools for advancing population genetics and precision medical research. However, there has been a scarcity of research concentrating on the whole genome of ethnic minority groups. To fill this gap, we developed the Guizhou Multi-ethnic Genome Database (GMGD). It comprises whole genome sequencing data from 476 healthy unrelated individuals spanning 11 ethnic minorities groups in Guizhou Province, Southwest China, including Bouyei, Dong, Miao, Yi, Bai, Gelo, Zhuang, Tujia, Yao, Hui, and Sui. The GMGD database comprises more than 16.33 million variants in GRCh38 and 16.20 million variants in GRCh37. Among these, approximately 11.9% (1,956,322) of the variants in GRCh38 and 18.5% (3,009,431) of the variants in GRCh37 are entirely new and do not exist in the dbSNP database. These novel variants shed light on the genetic diversity landscape across these populations, providing valuable insights with an average coverage of 5.5 ×. This makes GMGD the largest genome-wide database encompassing the most diverse ethnic groups to date. The GMGD interactive interface facilitates researchers with multi-dimensional mutation search methods and displays population frequency differences among global populations. Furthermore, GMGD is equipped with a genotype-imputation function, enabling enhanced capabilities for low-depth genomic research or targeted region capture studies. GMGD offers unique insights into the genomic variation landscape of different ethnic groups, which are freely accessible at https://db.cngb.org/pop/gmgd/ .
