Culturally tailored lifestyle interventions for the prevention and management of type 2 diabetes in adults of Black African ancestry: a systematic review of tailoring methods and their effectiveness

Racial Differences in Discrepancies Between Subjective Ratings and Objective Assessments of Hearing Impairment

BACKGROUND AND OBJECTIVES

To better understand racial/ethnic disparities in hearing aid use, we examined racial differences in discrepancies between subjective hearing ratings and objective hearing tests as a potential source of this disparity.

RESEARCH DESIGN AND METHODS

A cross-sectional assessment was conducted using the data from the Health and Retirement Study (HRS). Our analytic sample included 2,568 participants aged 50 and older: 1,814 non-Hispanic White Americans and 754 non-Hispanic Black Americans. Discordant groups were identified based on self-ratings of hearing abilities (positive vs negative) and objective hearing test results (normal vs hearing loss).

RESULTS

Analysis of HRS data revealed that approximately 73% of participants with objectively measured hearing loss reported positive hearing ratings. False positive hearing rates were found to be 80% among Black older adults and 70% among their White counterparts. Odds for false positive hearing ratings were significantly greater for Black older adults, men, those with less than a high school education, more health conditions and depressive symptoms, and current smoking. Racial differences were maintained after adjustment for these covariates.

DISCUSSION AND IMPLICATIONS

While cost of hearing aids has been a predominant explanation of low hearing aid use in Black Americans, false positive perceptions of hearing abilities may also play a significant role as a psychosocial mechanism. Future studies examining racial/ethnic differences in possible psychosocial mechanisms for discrepancies between objective and subjective hearing could guide the development and evaluation of culturally appropriate educational interventions.

Risk of imbalanced glycemic pattern: diagnostic content validity

OBJECTIVE

To assess evidence of content validity of the diagnostic proposition "Risk of imbalanced glycemic pattern".

METHOD

Content validity study based on collective wisdom, with a quantitative approach. Sample composed of 51 participants who assessed the relevance and accuracy of 13 risk factors, 10 at-risk populations, and 16 associated conditions. For analysis, the content validity index was used, excluding diagnostic components that reached a value equal to or less than 0.5.

RESULTS

The diagnostic label and its definition achieved a content validity index of 0.98 and 0.94, respectively. The risk factors with the highest rates were inadequate blood glucose monitoring, inadequate knowledge of disease management, inadequate regularity of meal consumption, obesity, and overweight. No diagnostic component was excluded, as all of them presented evidence of content validity.

CONCLUSION

The diagnostic proposition Risk of imbalanced glycemic pattern reached adequate values for consideration of evidence of content validity.

A qualitative evaluation of the effectiveness of behaviour change techniques used in the Healthy Eating and Active Lifestyles for Diabetes (HEAL-D) intervention

BACKGROUND

Type 2 diabetes (T2D) is up to three times more common in people of Black African and Black Caribbean heritage living in the UK, compared to their White British counterparts. Structured education is the cornerstone of care but is less successful for people from minority ethnic groups. Healthy Eating and Active Lifestyles for Diabetes (HEAL-D) was developed to support diabetes self-management in people of Black African and Caribbean heritage living with T2D in the UK. The intervention was designed using COM-B/behaviour change wheel methodology to specify the theory of change. In a process evaluation study, we explored how the selected behaviour change techniques (BCTs) supported behaviour change in the intervention.

METHODS

Focus groups and interviews were conducted with participants who were randomised to receive the HEAL-D intervention in a feasibility trial. A topic guide directed discussions to explore experiences of HEAL-D, key learnings and impact, and behaviour change; the interviews gave the opportunity to probe further the focus group themes and areas requiring clarification. Sessions were audio-recorded and transcribed. Framework analysis was used to explore how the selected BCTs supported behaviour change in those attending HEAL-D.

RESULTS

Thirty-six participants took part in one or both activities (44% Black African, 50% Black Caribbean, 6% Mixed race; 61% female, 83% first-generation; mean age 59.5 years, SD 10.02). Participants reported increased physical activity, reduced carbohydrate portion size and engagement in weight monitoring behaviour. BCTs to increase social opportunity (social comparison, social support) and overcome motivational barriers (credible sources and modelling) were effective in addressing cultural barriers relating to diet, stigma and health beliefs. BCTs to develop capability (demonstration, instruction, information on health consequences) were effective because of the cultural salience of the developed components. Less impactful BCTs were problem solving, graded tasks, goal setting, and feedback on outcomes.

CONCLUSIONS

BCTs in the HEAL-D intervention were effective in supporting behaviour change, particularly those promoting social opportunity, as normative cultural habits and beliefs can conflict with diabetes self-management guidance. In addition, lifestyle interventions should include opportunity for experiential learning alongside culturally salient information provision.

A pilot mixed methods randomized control trial investigating the feasibility and acceptability of a culturally tailored intervention focused on beliefs, mistrust and race-congruent peer support for Black adults with diabetes

Introduction

Black adults disproportionately experience poor glycemic control and medication nonadherence, yet few diabetes self-management programs address their unique health beliefs, provider mistrust and sociocultural barriers to taking diabetes medications. This 6-month pilot randomized feasibility trial compared a culturally tailored diabetes self-management program, incorporating beliefs about diabetes, mistrust, and race-congruent peer support to a standard diabetes program.

Methods

An embedded mixed methods design examined the feasibility of the pilot trial, including recruitment, retention, intervention adherence and participant acceptability. Data were collected through participant self-reported questionnaires, field notes, semi-structured interviews, and focus groups. Qualitative content analysis inductively explored participants' feedback on the program, participation barriers and potential strategies to overcome the challenges. Mixed methods integration was implemented using a side-by-side joint display to compare, synthesize and interconnect the quantitative and qualitative results across all feasibility domains.

Results

Thirteen participants (93%) completed the trial, demonstrating high adherence and retention. Community outreach and a prerequisite orientation using motivational interviewing were feasible and appropriate to recruit potential participants. Participants expressed high satisfaction and acceptability, highlighting the importance of peer support, cultural relevant content and a safe space for sharing experiences. Barriers to participation were identified including schedule conflicts and difficulties in engagement.

Discussion

Future large-scale effectiveness trials should consider combining multimedia into recruitment methods, tailoring the program to address medication-taking goals, and addressing social and environmental barriers to support sustained lifestyle changes.

Patient-oriented unsupervised learning to uncover the patterns of multimorbidity associated with stroke using primary care electronic health records

BACKGROUND

We aimed to identify and characterise the longitudinal patterns of multimorbidity associated with stroke.

METHODS

We used an unsupervised patient-oriented clustering approach to analyse primary care electronic health records (EHR) of 30 common long-term conditions (LTC) in patients with stroke aged over 18, registered in 41 general practices in south London between 2005 and 2021.

RESULTS

Of 849,968 registered patients, 9,847 (1.16%) had a record of stroke and 46.5% were female. The median age at record of stroke was 65.0 year (IQR: 51.5-77.0) and the median number of LTCs in addition to stroke was 3 (IQR: 2-5). We identified eight clusters of multimorbidity with contrasted socio-demographic characteristics (age, gender, and ethnicity) and risk factors. Beside a core of 3 clusters associated with conventional stroke risk-factors, minor clusters exhibited less common combinations of LTCs including mental health conditions, asthma, osteoarthritis and sickle cell anaemia. Importantly, complex profiles combining mental health conditions, infectious diseases and substance dependency emerged.

CONCLUSION

This novel longitudinal and patient-oriented perspective on multimorbidity addresses existing gaps in mapping the patterns of stroke-associated multimorbidity not only in terms of LTCs, but also socio-demographic characteristics, and suggests potential for more efficient and patient-oriented healthcare models.

Culturally Tailored Lifestyle Modification Strategies for Hypertension Management: A Narrative Review

Hypertension (HTN) is a significant global health challenge affecting billions of individuals worldwide. The prevalence of HTN varies considerably across the globe due to diverse factors, such as lifestyle influenced by culture, genetics, health care access, and socioeconomic conditions. Lifestyle modification has a substantial impact on blood pressure management; however, some cultural practices and behaviors affect recommended lifestyle modification strategies for HTN management. The purpose of this review was to explore lifestyle modification strategies for HTN management from a cultural perspective. Lifestyle modification, including physical activity, stress reduction, changes in dietary patterns (adopting a low-sodium diet and intake of fruit and vegetables), and weight management, provide an effective non-pharmacologic intervention for the management of hypertension. Individual's cultural practices have the potential to determine their diet, physical activity levels, knowledge, and perception about HTN, adherence to treatment and medications, and the use of local herbal preparations for HTN management. Culture focuses on individuals' belief, practices and how these beliefs and practices influence their lifestyle behaviors for HTN management. It is important to consider patients' cultural beliefs before recommending lifestyle behaviors for HTN management.

Periodontal diseases in Africa

Periodontal diseases, a group of complex conditions marked by an excessive immune response and periodontal tissue destruction, are a global health concern. Since 1990, the incidence of these diseases has doubled, with Western sub-Saharan Africa experiencing the highest burden. Accurate diagnosis and case identification are crucial for understanding the etiology, features of disease, research, treatment and prevention. Modern perspectives on periodontal disease classification are based on commonality among those affected. However, current literature is often plagued by methodological inconsistencies and focused on disease mechanisms in European populations. Health inequalities in low- and middle-income countries (LMICs) are exacerbated by these challenges, with sub-Saharan Africa, and Nigeria specifically, facing unique difficulties such as clinical personnel shortages and limited research infrastructure. This review explored disparities in periodontal disease research, care and outcomes in African populations. We highlighted these disparities and identified the factors contributing to inequities in periodontal health outcomes. We further demonstrated the critical need for inclusive and equitable healthcare and research practices tailored to the unique challenges faced by diverse populations and regions with limited resources. Addressing these disparities is essential for ensuring that advancements in healthcare are accessible to all, thereby improving global oral health and general health.

Feasibility of the MIND+SOUL Culturally Tailored Brain Healthy Diet: A Pilot Study

Alzheimer's disease (AD) disproportionately impacts Black Americans, who are three times more likely to develop AD. While heart-healthy diets have shown potential in reducing AD risk, research on adapted dietary interventions for Black American communities remains limited. This pilot study assessed the feasibility and acceptability of an adapted brain healthy diet intervention (MIND + SOUL) and explored changes in cardiometabolic risk and cognition. Twenty-nine participants completed the 12-week intervention, which included culturally tailored health education, cooking classes, health coaching, and groceries. Feasibility was assessed by attendance and retention rates, while acceptability was measured by two questionnaires. Participants had a mean age of 70.3, with 10.3% male. The intervention demonstrated high feasibility (89.3% retention) and acceptability (mean = 71.9, SD = 8.59), with meaningful improvements in body mass index (estimate = -0.54, P = 0.009), dietary intake (estimate = 28.39, P = 0.042), and executive function (estimate = 3.32, P < 0.001). However, no significant changes in blood-based biomarkers were observed. The MIND + SOUL intervention demonstrated high feasibility and acceptability, improvements in body composition, cognitive function, and dietary behaviors, despite no significant changes in blood-based biomarkers. Findings suggest potential benefits for reducing AD risk factors and promoting healthy aging. Clinical Trials Registry: ClinicalTrials.Gov; NCT05414682.

Lifestyle Intervention in Reducing Insulin Resistance and Preventing type 2 Diabetes in Asia Pacific Region: A Systematic Review and Meta-Analysis

PURPOSE OF REVIEW

To update the evidence of lifestyle interventions for the prevention of type 2 diabetes mellites (T2DM) in adults, particularly in the Asia Pacific region. The key questions to ask are: 1) How effective are lifestyle interventions in preventing T2DM among at-risk adults in the Asia Pacific Region? 2)What are the key characteristics of the implementation of lifestyle interventions for diabetes prevention?

RECENT FINDINGS

Lifestyle interventions for the prevention of T2DM have been suggested to be effective. There is evidence of ethnic differences in some glycaemic and anthropometric outcomes. The meta-analysis suggested a significant result in reducing waist circumference (standardised mean difference - 019, 95%CI ( -0.31, -0.06)), and no significant effects in other outcomes. However, the implementation outcomes suggested lifestyle intervention might be a cost-effective and sustainable approach in T2DM particularly in countries in the Asia Pacific Region. The focus of lifestyle intervention in the Asia Pacific Region should not only lie in the effectiveness of the trial but a thorough evaluation of the implementation outcomes, as well as cultural adaptations, with the support of all stakeholders through all stages of the implementation.

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.

Reducing CVD health disparities in Black women through addressing social determinants of health (SDOH): a scoping review

Cardiovascular disease (CVD) disparities among Black American women can be linked directly to social determinants of health (SDOH). This scoping review examines the breadth and depth of existing literature on CVD risk reduction interventions in young-to-middle-aged women that address SDOH. We searched PubMed, CINAHL, Scopus and Google Scholar for relevant peer-reviewed articles published in English. We included studies if they reported on the feasibility, acceptability, or findings of a CVD risk reduction intervention, addressed at least one SDOH domain, and included Black women 18-45 years of age. Of the 2,533 studies screened, 5 studies were eligible for inclusion. Specific SDOH domains addressed included: social and community context and health-care access and quality. All but one study reported culturally tailored intervention components. Feasibility and acceptability of culturally tailored interventions was high among included studies examining this outcome. Recommendations for future research focused on the need for additional interventions that were culturally tailored to young- and middle-aged Black women. Future research should work to address existing evidence gaps via development and implementation of culturally tailored, CVD risk reduction and disease prevention interventions for young-to-middle-aged Black women that focus addressing SDOH, as these types of interventions demonstrate promise for reducing CVD health disparities among Black women.

The Development and Psychometric Testing of the Scale of Cultural Sensitivity of Health Care Professionals in Japan

INTRODUCTION

The development of cultural sensitivity is essential for health care professionals but there are few tools to measure this quality in Japan. The purpose of this study was to develop a scale of cultural sensitivity for Japanese health care professionals and examine its reliability and validity.

METHOD

A draft scale was created through conceptual analysis and a questionnaire was completed by 515 health care professionals and 1,322 college students. Exploratory and confirmatory factor analyses were used to determine suitable scale items and examine model fitness.

RESULTS

The four-factor 18-item scale showed acceptable model fitness. Cronbach's α coefficient exceeded .90 and correlation coefficients for criterion-related validity were over .29. Construct validity was confirmed by the significantly higher score of the cross-culturally experienced groups. The intraclass correlation coefficient was .642 (professionals) and .722 (students).

DISCUSSION

This reliable and valid scale for Japanese health professionals and college students may be used to evaluate training programs to increase their cultural sensitivity.

Adults' perceived health promotion needs in the prediabetes stage: a meta-synthesis study

Introduction

One of the methods to promote pre-diabetic patients' adherence to preventive behaviors and improving their lifestyle is to pay attention to their needs in the designed educational programs. Therefore, this study was conducted with the aim of identifying the needs of individuals with prediabetes.

Methodology

Three databases, including ISI/Web of Sciences, PubMed, Scopus were searched without time limitation until August 2022. The quality of the included studies was assessed using the Critical Appraisal Skills Programme tool. This study was reported according to the Enhancing Transparency in Reporting the Synthesis of Qualitative Research guidelines and to achieve the research goal, Sandelowski and Barroso's seven-step meta-synthesis method (2007) was used. Thematic synthesis was used to analyses the data.

Results

Out of the 1934 studies obtained, 34 studies were finally examined and 805 codes were recorded based on the extracted data. Through synthesizing and analyzing the primary studies, 8 main themes were extracted regarding individuals' needs in the prediabetes stage: Information needs, Cultural needs, psychological needs, Social support needs, Education needs, Financial needs, Service needs and Skill needs.

Discussion and Conclusions

The perceived needs and their types in each of the dimensions in detail can be a proper guide for designing educational programs and various interventions to control the prediabetes condition, leading to a reduction in the prevalence of type 2 diabetes in the society.

Environmental, Sociocultural, Behavioral, and Biological Factors Associated with Cognitive Decline, Alzheimer's Disease, and Other Types of Dementia in Black Americans

Purpose of Review

This narrative review summarizes environmental, sociocultural, behavioral, and biological factors associated with cognitive decline and dementia in Black Americans.

Recent Findings

Variations in environmental factors (education, toxins) contribute to poor cognition in Blacks. Historical context, early-life educational experiences, and environmental exposures should be considered for addressing late-life cognitive disparities. Sociocultural (stress, discrimination, social networks, social activity, loneliness) and behavioral (depression, coping, health behaviors) factors can have positive and negative implications for cognitive aging. Given these factors are not consistently shown to play a role in maintaining cognition in Blacks, further examination is needed. Cardiometabolic conditions increase the risk of cognitive issues and are more common in Blacks; thus, examination of biological mechanisms (inflammation, vascular changes, etc.) warrants further study.

Summary

Future studies should explore the impact of education and segregation and identify mechanisms linking stress and discrimination to cognitive outcomes. Further, culturally tailored programs focused on preventative behaviors are needed to enhance health outcomes and reduce disparities.

Current evidence for designing self-management support for underserved populations: an integrative review using the example of diabetes

AIMS

With numerous and continuing attempts at adapting diabetes self-management support programmes to better account for underserved populations, its important that the lessons being learned are understood and shared. The work we present here reviews the latest evidence and best practice in designing and embedding culturally and socially sensitive, self-management support programmes.

METHODS

We explored the literature with regard to four key design considerations of diabetes self-management support programmes: Composition - the design and content of written materials and digital tools and interfaces; Structure - the combination of individual and group sessions, their frequency, and the overall duration of programmes; Facilitators - the combination of individuals used to deliver the programme; and Context - the influence and mitigation of a range of individual, socio-cultural, and environmental factors.

RESULTS

We found useful and recent examples of design innovation within a variety of countries and models of health care delivery including Brazil, Mexico, Netherlands, Spain, United Kingdom, and United States of America. Within Composition we confirmed the importance of retaining best practice in creating readily understood written information and intuitive digital interfaces; Structure the need to offer group, individual, and remote learning options in programmes of flexible duration and frequency; Facilitators where the benefits of using culturally concordant peers and community-based providers were described; and finally in Context the need to integrate self-management support programmes within existing health systems, and tailor their various constituent elements according to the language, resources, and beliefs of individuals and their communities.

CONCLUSIONS

A number of design principles across the four design considerations were identified that together offer a promising means of creating the next generation of self-management support programme more readily accessible for underserved communities. Ultimately, we recommend that the precise configuration should be co-produced by all relevant service and patient stakeholders and its delivery embedded in local health systems.

Development and Validation of COVID-19 Vaccine Messaging Materials for Latinx Communities

With pervasive health misinformation and mistrust, many of those at greatest risk from COVID-19 have demonstrated lower vaccine acceptance. In Chicago, IL, surveillance data has revealed lower rates of vaccine uptake among Black and Latinx individuals compared with others. We partnered with two local federally qualified health centers (FQHCs) to develop and implement language-concordant, low literacy patient education materials to promote COVID-19 vaccine knowledge, acceptance, and uptake. Our multi-phase study included: 1) iterative content generation and refinement by health literacy experts, health center providers and staff, and community-dwelling adults; and 2) materials testing via a two-arm randomized experiment among adults from Latinx communities in the Chicagoland area. Results indicate that our English and Spanish-language COVID-19 Fact Sheets increase knowledge about COVID-19 vaccination. These materials are publicly available and can be used by health centers or community organizations to promote COVID-19 vaccination among diverse populations.
