A Systematic Review of Literature on Culturally Adapted Obesity Prevention Interventions for African American Youth

Group Randomized Trial of Healthy Eating and Gardening Intervention in Navajo Elementary Schools (Yéego!)

Introduction

Few healthy eating, school-based interventions have been rigorously evaluated in American Indian communities. Gardening and healthy eating are priorities in the Navajo Nation. Collaborations between researchers and local partners supported the design and implementation of this project.

Design

The Yéego! Healthy Eating and Gardening Study was a group-randomized controlled trial to evaluate a school-based healthy eating and gardening intervention in 6 schools in the Navajo Nation. Schools were randomized 1:2 to intervention or comparison.

Setting/participants

The Shiprock and Tsaile/Chinle areas in the Navajo Nation were selected. Elementary schools were screened for eligibility. All students in third and fourth grades were invited to participate in the assessments.

Intervention

Delivered during 1 school year in the intervention schools, the intervention included a culturally relevant nutrition and gardening curriculum and a school garden.

Main outcome measures

Student self-efficacy for eating fruits and vegetables, student self-efficacy for gardening, and student healthy foods score from a modified Alternative Healthy Eating Index were assessed in third and fourth graders at the beginning and end of a school year affected by the COVID-19 pandemic. Primary analyses used repeated measures linear mixed models accounting for students nested within schools to estimate the intervention effect and 95% CIs.

Results

Students in the intervention schools had self-efficacy scores for eating fruits and vegetables that were 0.22 points greater (95% CI=0.04, 0.41) than those in the comparison schools, although the student healthy foods score increased in the intervention schools by 2.0 (95% CI=0.4, 3.6); the differential change was modest at 1.7 (95% CI=-0.3, 3.7). The self-efficacy to grow fruits and vegetables in the school garden increased among those in the intervention schools (OR=1.92; 95% CI=1.02, 3.63) but not significantly more than it increased in the comparison schools (OR=1.29; 95% CI=0.60, 2.81).

Conclusions

The intervention was efficacious in improving self-efficacy for eating fruits and vegetables among third- and fourth-grade students over a school year. The findings warrant further evaluation of the intervention in larger-group randomized trials with schools in Navajo communities.

Cultural adaptations of obesity-related behavioral prevention interventions in early childhood: A systematic review

Interventions for obesity prevention can effectively reduce obesity-related behaviors in young children. Understanding how to leverage and adapt evidence-based interventions is needed to improve reach among culturally and linguistically diverse families. This systematic review aimed to synthesize the approaches and outcomes of culturally adapted early childhood obesity-related behavioral prevention interventions. Multiple electronic databases were systematically searched in March 2021. All study designs were included if they reported cultural adaptations of an intervention targeting at least one obesity-related behavior (infant feeding, nutrition, physical activity, and/or sleep) among children aged 0-5 years. Studies that only conducted language translations or that developed new interventions were excluded. Two authors independently conducted critical appraisals using the Mixed Method Appraisal Tool. Findings were synthesized narratively, based on the Stages of Cultural Adaptation theoretical model and the Framework for Reporting Adaptations and Modifications-Enhanced. Twelve interventions met the inclusion criteria, with varied study designs. Few reported all aspects of cultural adaptation processes, and the cultural adaptation strategies documented varied. The results suggest that cultural adaptation of obesity-related behavioral prevention interventions targeting young children increases acceptability among target cultural groups, yet effectiveness is inconclusive due to a lack of trials. More detailed reporting of cultural adaptation processes and further effectiveness trials are needed to evaluate future work.

Interventions to promote dementia knowledge among racial/ethnic minority groups: A systematic review

BACKGROUND

Certain racial/ethnic minority groups have a higher risk of developing dementia, yet studies have demonstrated that they often have limited knowledge and understanding of this disease. An increasing number of educational and advocacy programs have been developed to promote dementia knowledge. We aimed at assessing current evidence and quality regarding educational interventions for promoting dementia knowledge.

METHODS

We searched for intervention studies published in English that focused on educational interventions for promoting dementia knowledge among racial/ethnic minority groups. We identified 25 relevant studies through PubMed, PsycINFO, CINAHL, and Scopus, using tailored search terms. We screened titles and abstracts, reviewed full texts, synthesized relevant evidence, and evaluated the studies' quality based on the Mixed Methods Appraisal Tool. Relevant intervention studies took place in communities, hospitals or clinics, and schools, and online.

RESULTS

Most studies were conducted in the United States (n = 21), followed by the UK (n = 3). Over half of the studies included Asian/Pacific Islander groups (n = 14), followed by Black groups (n = 12) and Hispanic groups (n = 11). The intervention delivery mode varied across studies-from workshops hosted in a faith community to talk shows on YouTube. Target populations included middle-aged and older adults, caregivers and family members, health students and professionals, and elementary school students. Common content included symptoms and signs of dementia, protective and risk factors, and local resources. The assessment of study outcomes varied across studies. Improvement in dementia knowledge and attitudes towards dementia was reported in many studies. Among the included studies, intervention satisfaction was high. The overall quality of the interventions was low.

CONCLUSION

Formally evaluated educational interventions promoting dementia knowledge are at an early stage. Existing published interventions showed adequate acceptability and promise in promoting better understanding and awareness of dementia in minority groups. More well-designed randomized controlled trials are needed.

Strategies and interventions for healthy adolescent growth, nutrition, and development

Adolescence is a pivotal point in the life course, characterised by transformative physical, cognitive, and emotional growth, an openness to change, and a drive to reshape the social environment. It offers unique opportunities to adopt changes in diet and physical activity that can persist into later life. Yet pre-existing nutritional problems, including micronutrient deficiencies, food insecurity, and poor-quality diets, persist at the same time as adolescents face the rapid emergence of an obesity epidemic. Adolescent growth and nutrition has been largely overlooked in intervention and policy research. Most intervention studies have emphasised micronutrient supplementation, with few taking into account the multiple drivers of adolescent diets. This Series paper highlights that effective interventions and policies will need to cut across sectors; be supported by multifaceted and multilevel policy; and extend across education, health, food systems, social protection, and digital media. Better data standardisation and systems will be essential in coordinating and monitoring these responses. In a context of shifts in planetary ecosystems and commercial drivers, resilient food systems will need to both ensure access to healthy and affordable foods and provide the infrastructure and incentives for continuing physical activity. Intergenerational partnerships with young people will be essential in bringing about transformative change and ensuring that food policies reflect their needs and aspirations.

Engaging School and Family in Navajo Gardening for Health: Development of the Yéego Intervention to Promote Healthy Eating among Navajo Children

Objective

Navajo children are at increased risk for obesity, in part due to limited access to healthy foods. School garden interventions have been shown to increase access to fresh fruit and vegetables and consumption of healthy foods. Our study describes the development and pilot testing of a school garden intervention for Navajo elementary school children.

Methods

We reviewed existing school garden interventions and conducted formative research with students, caregivers, and school staff to inform the intervention. The intervention consisted of a garden built at the school and a yearlong curriculum on gardening and healthy eating. We pilot tested the intervention in an elementary school on the Navajo Nation.

Results

Formative research revealed the importance of incorporating Diné culture, including traditional growing practices and the preparation of traditional foods into the curriculum. School staff also stressed the value of tying the curriculum to state and Diné educational standards. Students enjoyed opportunities for hands-on activities and snack preparation.

Conclusions

Schools have a meaningful role to play in addressing childhood obesity disparities among Navajo children. School-based interventions that draw on cultural strengths and include healthy traditional practices can be a promising strategy for increasing fruit and vegetable consumption.

Health promotion interventions for African Americans delivered in U.S. barbershops and hair salons- a systematic review

BACKGROUND

African American adults suffer disproportionately from obesity-related chronic diseases, particularly at younger ages. In order to close the gap in these health disparities, efforts to develop and test culturally appropriate interventions are critical.

METHODS

A PRISMA-guided systematic review was conducted to identify and critically evaluate health promotion interventions for African Americans delivered in barbershops and hair salons. Subject headings and keywords used to search for synonyms of 'barbershops,' 'hair salons,' and 'African Americans' identified all relevant articles (from inception onwards) from six databases: Academic Search Ultimate, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Embase, PsycINFO, PubMed, Web of Science (Science Citation Index and Social Sciences Citation Index). Experimental and quasi-experimental studies for adult (> 18 years) African Americans delivered in barbershops and hair salons that evaluated interventions focused on risk reduction/management of obesity-related chronic disease: cardiovascular disease, cancer, and type 2 diabetes were included. Analyses were conducted in 2020.

RESULTS

Fourteen studies met criteria for inclusion. Ten studies hosted interventions in a barbershop setting while four took place in hair salons. There was substantial variability among interventions and outcomes with cancer the most commonly studied disease state (n = 7; 50%), followed by hypertension (n = 5; 35.7%). Most reported outcomes were focused on behavior change (n = 10) with only four studies reporting clinical outcomes.

CONCLUSIONS

Health promotion interventions delivered in barbershops/hair salons show promise for meeting cancer screening recommendations and managing hypertension in African Americans. More studies are needed that focus on diabetes and obesity and utilize the hair salon as a site for intervention delivery.

Theoretical model of nursing care for children with obesity

OBJECTIVES

to describe a theoretical model of nursing care for children with obesity in Primary Health Care.

METHODS

Grounded Theory and the theoretical/philosophical framework of Virginia Henderson were used. The research was conducted in Family Basic Health Units and in Specialized Services in the city of Campina Grande, Paraíba, Brazil. A total of 24 participants composed four sample groups. Data were collected through semi-structured interviews, between April and October 2015, and analyzed by the constant comparison method. The analysis occurred by initial coding, construction of diagrams and memos, axial coding, selective coding and reflection on the paradigm and on the emerging theory.

RESULTS

six categories emerged from the data. Nurses worrying about the care of children with obesity as a neglected area in Primary Health Care was the theoretical model.

FINAL CONSIDERATIONS

the phenomenon is related to the individuality of nursing care and the need for shared responsibilities.

Cultural Connectedness as Obesity Prevention: Indigenous Youth Perspectives on Feast for the Future

OBJECTIVE

To describe a community-based obesity-prevention initiative that promoted cultural connectedness and traditional food revitalization and gained insight into youth participants' perspectives on the program through a photovoice methodology.

METHODS

Photovoice methods were used with fourth- and fifth-grade youths (aged 9-11 years) in the US Southwest who had participated in the Feast for the Future program. A total of 44 youths from 3 communities met for 8-9 sessions; they took photos of current food environments and traditional food systems, and discussed them as well as Feast for the Future and hopes for the future, and then prepared a final presentation. Photovoice sessions were recorded, transcribed verbatim, then open coded using Atlas.ti.

RESULTS

Five common themes emerged: traditional food is farmed or gardened, traditional foods are healthy, Feast for the Future supported positive connections to culture, hope for more farming or gardening for future generations, and store or less nutrient-dense food is unhealthy.

CONCLUSIONS AND IMPLICATIONS

Photovoice can be an effective way to engage Indigenous youths in conversations about their culture and food environments. The findings suggest that attention to revitalizing traditional food systems and supporting cultural connectedness may be an effective approach to obesity prevention in tribal communities, although future research would be needed to assess the impact of the intervention on obesity rates.

Protocol for a systematic review of health promotion interventions for African Americans delivered in US barbershops and hair salons

INTRODUCTION

African American adults are disproportionately burdened by chronic diseases, particularly at younger ages. Developing culturally appropriate interventions is paramount to closing the gap in these health inequities. The purpose of this systematic review is to critically evaluate health promotion interventions for African Americans delivered in two environments that are frequented by this population: barbershops and hair salons. Characteristics of effective interventions will be identified and evidence for the effectiveness of these interventions will be provided. Results of this review will inform future health promotion efforts for African Americans particularly focused on the leading health inequities in obesity-related chronic diseases: cardiovascular disease, cancer and type 2 diabetes.

METHODS AND ANALYSIS

Subject headings and keywords will be used to search for synonyms of 'barbershops,' 'hair salons' and 'African Americans' to identify all relevant articles (from inception onwards) in the following databases: Academic Search Ultimate, Cumulative Index of Nursing and Allied Health Literature, Embase, PsycINFO, PubMed, Web of Science (Science Citation Index and Social Sciences Citation Index) and ProQuest Dissertations. Experimental and quasi-experimental studies for adult (>18 years) African Americans delivered in barbershops and hair salons will be included. Eligible interventions will include risk reduction/management of obesity-related chronic disease: cardiovascular disease, cancer and type 2 diabetes. Two reviewers will independently screen, select and extract data and a third will mediate disagreements. The methodological quality (or risk of bias) of individual studies will be appraised using the Effective Public Health Practice Project Quality Assessment Tool. Quality and content of the evidence will be narratively synthesised.

ETHICS AND DISSEMINATION

Since this is a protocol for a systematic review, ethical approval is not required. Findings from the review will be widely disseminated through conference presentations, peer-reviewed publications and traditional and social media outlets.

A weight management programme for fathers of children aged 4–11 years: cultural adaptation and the Healthy Dads, Healthy Kids UK feasibility RCT

Background

More men than women in the UK are living with overweight or obesity, but men are less likely to engage with weight loss programmes. Healthy Dads, Healthy Kids is an effective Australian weight management programme that targets fathers, who participate with their primary school-aged children. Behavioural interventions do not always transfer between contexts, so an adaptation of the Healthy Dads, Healthy Kids programme to an ethnically diverse UK setting was trialled.

Objectives

To adapt and test the Australian Healthy Dads, Healthy Kids programme for delivery to men in an ethnically diverse, socioeconomically disadvantaged UK setting.

Design

Phase 1a studied the cultural adaptation of the Healthy Dads, Healthy Kids programme and was informed by qualitative data from fathers and other family members, and a theoretical framework. Phase 1b was an uncontrolled feasibility trial. Phase 2 was a randomised controlled feasibility trial.

Setting

Two ethnically diverse, socioeconomically disadvantaged UK cities.

Participants

In phase 1a, participants were parents and family members from black and minority ethnic groups and/or socioeconomically deprived localities. In phases 1b and 2, participants were fathers with overweight or obesity and their children aged 4–11 years.

Interventions

The adapted Healthy Dads, Healthy Kids intervention comprised nine sessions that targeted diet and physical activity and incorporated joint father–child physical activity. Healthy Dads, Healthy Kids was delivered in two programmes in phase 1b and four programmes in phase 2. Those in the comparator arm in phase 2 received a family voucher to attend a local sports centre.

Main outcome measures

The following outcomes were measured: recruitment to the trial, retention, intervention fidelity, attendance, feasibility of trial processes and collection of outcome data.

Results

Forty-three fathers participated (intervention group, n = 29) in phase 2 (48% of recruitment target), despite multiple recruitment locations. Fathers’ mean body mass index was 30.2 kg/m2 (standard deviation 5.1 kg/m2); 60.2% were from a minority ethnic group, with a high proportion from disadvantaged localities. Twenty-seven (63%) fathers completed follow-up at 3 months. Identifying sites for delivery at a time that was convenient for the families, with appropriately skilled programme facilitators, proved challenging. Four programmes were delivered in leisure centres and community venues. Of the participants who attended the intervention at least once (n = 20), 75% completed the programme (attended five or more sessions). Feedback from participants rated the sessions as ‘good’ or ‘very good’ and participants reported behavioural change. Researcher observations of intervention delivery showed that the sessions were delivered with high fidelity.

Conclusions

The intervention was well delivered and received, but there were significant challenges in recruiting overweight men, and follow-up rates at 3 and 6 months were low. We do not recommend progression to a definitive trial as it was not feasible to deliver the Healthy Dads, Healthy Kids programme to fathers living with overweight and obesity in ethnically diverse, socioeconomically deprived communities in the UK. More work is needed to explore the optimal ways to engage fathers from ethnically diverse socioeconomically deprived populations in research.

Developing a Socioculturally Nuanced Systems Model of Childhood Obesity in Manhattan's Chinese American Community via Group Model Building

The purpose of this study was to develop a qualitative and socioculturally tailored systems model of childhood obesity in the Chinese American community in Manhattan's Chinatown. We utilized group model building (GMB) methodology as a form of participatory systems modeling. The study was conducted in Manhattan's Chinatown community. We recruited 16 Chinese American adults from the community. GMB workshops engendered a causal loop diagram (CLD), the visualization of a complex systems model illustrating the structures, feedbacks, and interdependencies among socioculturally specific pathways underlying childhood obesity, in Manhattan's Chinatown community. The analysis of CLD revealed that participants considered the following factors to influence childhood obesity: (1) traditional social norms affecting body image, how children are raised, parental pressure to study, and trust in health of traditional foods; (2) grandparents' responsibility for children; (3) limited time availability of parents at home; and (4) a significant amount of children's time spent indoors. GMB represents a novel method to understand the complexity of childhood obesity in culturally specific populations and contexts. The study identified sociocultural subsystems that may underlie the development and perpetuation of childhood obesity among Chinese American children. Insights from the study can be useful in the design of future empirical studies and interventions.

[Socio-Culturally Sensitive Disease Prevention and Health Promotion: Development of a Theoretical Framework and Results of a Survey of Physical Activity Promotion Projects.]

OBJECTIVE

To develop a framework for socio-culturally sensitive disease prevention and health promotion and to assess which components of socio-cultural appropriateness are used in physical activity projects targeting migrants.

METHODS

Based on 9 expert interviews and a rapid review in PubMed and PsycInfo, we identified domains and strategies of socio-cultural sensitivity for disease prevention and health promotion. The domains were used as a basis for a survey of physical activity projects targeting migrants as listed in a national project data base ("Gesundheitliche Chancengleichheit").

RESULTS

We identified 5 domains for socio-cultural adaptation of prevention programs (peripheral, evidential, linguistic, constituent-involving and socio-cultural strategies). Using multiple strategies seems to increase the efficacy of the interventions. Of the 48 contacted projects, 29 participated in the survey. Almost all projects used strategies from 4 of the 5 domains. Evidential strategies were used to a lesser extent.

CONCLUSIONS

The developed framework can be used for both, planning and evaluating prevention programs targeting migrants. The project survey shows how socio-cultural appropriateness can be improved through a variety of strategies.
