Designing the Healthy Eating and Active Lifestyles for Diabetes (HEAL-D) self-management and support programme for UK African and Caribbean communities: a culturally tailored, complex intervention under-pinned by behaviour change theory

Td2Ast project: A pragmatic intervention on diet and physical activity for patients with type 2 diabetes mellitus

AIM

The purpose of this study was to assess the efficacy of an educational intervention based on the Behavior Change Wheel (BCW) framework for individuals with type 2 diabetes mellitus (T2DM) on dietary and physical activity recommendations in a Spanish region.

METHODS

A two-arm pragmatic randomized pilot trial was developed. The intervention consisted of a 6-month period with three components: face-to-face counseling, a phone call, and specially designed written guidelines focusing on dietary and physical activity recommendations The primary outcome was changes in dietary and physical activity recommendations. The secondary outcome, the impact of the intervention on HbA1c levels, body mass index, and the frequency of consultations to primary care.

RESULTS

n=208 patients were recruited. Individuals in the intervention experienced a significative improvement in adherence to dietary recommendations (+0.52; p-value<0.001), physical activity (+0.79; p-value<0.001), and a decrease in HbA1c levels (0.11 %; p-value=0.04).

CONCLUSION

The 6-month intervention, designed for T2DM patients and based on the BCW model, has demonstrated effectiveness in improving adherence to healthy dietary and physical activity recommendations, as well as reducing HbA1c levels.

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.

HEAL-D Online: Exploring the potential for the spread and adoption of a virtual culturally tailored diabetes self-management programme for adults of African and Caribbean heritage

BACKGROUND

People of African and Caribbean heritage in the UK have a higher prevalence of Type 2 Diabetes (T2D) and poorer health outcomes than white Europeans. Healthy Eating and Active Lifestyles for Diabetes Online (HEAL-D Online) is a co-designed, culturally tailored T2D self-management programme for black African and Caribbean adults, which, due to online delivery, is well positioned for spread. This qualitative evaluation uses the Exploration-Preparation-Implementation-Sustainment (EPIS) framework to explore factors affecting scale-up from delivery and commissioning perspectives.

METHODS

Semi-structured interviews were conducted with nine commissioners and providers of T2D services from three English areas with varying population characteristics to explore scale-up. Focus groups were held with 15 people of African and Caribbean heritage with T2D lived experience to explore the impact of a digital model of participation. Data were analysed using thematic analysis, with themes mapped onto the EPIS framework exploration phase constructs to consider the outer and inner contextual factors for planning implementation.

RESULTS

Six EPIS constructs were identified by commissioners and providers as key in scaling HEAL-D Online. People with T2D lived experience explored the online mode of delivery, using the patient advocacy construct as the analytical lens. In delivering an online T2D programme, two themes were identified: (1) aligning course content with people's preferences; (2) practicalities to ensure online delivery was acceptable and accessible to the community.

CONCLUSIONS

HEAL-D Online was acceptable with the potential to help address health inequalities. The EPIS framework provided a structure to understand factors in planning scale-up for an intervention targeting underserved communities.

Behavioral Intervention Functions in Type 2 Diabetes Apps: Literature Review

BACKGROUND

As type 2 diabetes (T2D) is expected to increase, self-management becomes more crucial. Mobile apps are increasingly supporting self-management with tasks like blood glucose monitoring and medication management. Understanding the behavioral intervention functions used by diabetes apps today, is essential for improving future apps and systems for diabetes management.

OBJECTIVE

To analyze the behavioral intervention functions used in apps for managing T2D that integrate the three main elements: medication management, nutrition tracking, and blood glucose management.

METHODS

We conducted a literature review on T2D diabetes apps using SCOPUS, PubMed, and PsycINFO. After screening and removing duplicates, we analyzed app details and behavioral intervention functions based on the Behavior Change Wheel (BCW) framework.

RESULTS

We reviewed 644 scientific publications describing diabetes apps in clinical studies, narrowing it down to 20 studies, including 16 unique apps, after screening and exclusions. These studies were published between 2016 and 2024. Among the identified apps, automatic processing of medication data was reported in one study, while blood glucose data were automatically processed in 13 studies. Nutrition data processing varied. Most apps used Enablement and Persuasion as behavioral intervention functions, with Education and Training reported less frequently. Environmental Restructuring, Incentivization, Coercion, Restriction, and Modeling were not reported as being used in any studies.

CONCLUSIONS

This review shows that while Enablement and Persuasion are common, other behavioral intervention functions seem to be underused or underreported. Future research could explore the potential of integrating additional behavioral intervention functions to enhance diabetes app efficacy and users' self-management.

Phone call for diabetic people: protocol for a pragmatic, type 1 effectiveness-implementation hybrid clinical trial

OBJECTIVE

To describe an implementation study protocol for an intervention based on educational guidelines focused on seven self-care behaviors, through phone calls to individuals with type 2 diabetes.

METHOD

We will conduct a hybrid type 1 effectiveness-implementation pragmatic randomized clinical trial, with 198 individuals with type 2 diabetes on insulin therapy, from the Glycemic Self-Monitoring Program of two Primary Health Care in the city of São Paulo and three in Campinas, located in the state of Sao Paulo. Patients will be allocated in a 1:1 ratio to either the intervention or control group. Both groups will receive standard care, with the intervention group also receiving a phone call. During the call, nurses will provide guidance based on seven self-care behaviors, known as The ADCES7 Self-Care Behaviors™. Evaluations will happen at the baseline, and after 3- and 6-months post initiation of the trial. Glycemic levels and adherence to self-care behaviors will be compared before and after the intervention using multiple linear regression models. Through interviews with participants from the intervention group, implementation determinants based on the Capability, Opportunity, Motivation-Behavior (COM-B) model, and implementation outcomes feasibility, acceptability, and appropriateness will be evaluated.

EXPECTED OUTCOMES

We will evaluate the effectiveness of an intervention while exploring contextual conditions for its implementation in clinical practice of Primary Health Care. This study will provide preliminary evidence on the effectiveness of educational guidance through nurse-led telephone calls, as well as implementation determinants and outcomes in the clinical practice of Primary Health Care. Its results are important for expanding this assistance in locations where nursing consultation for people with diabetes is absent, hindered, or restricted. Study is registered on the ReBEC platform.

Navigating the food environment: Experiences of reduced calorie interventions to manage Type 2 Diabetes Mellitus

Research into achieving Type 2 Diabetes Mellitus remission through weight loss efforts has grown steadily in the past decade. Most of this research has focused on the effectiveness of weight loss as a method to achieve remission, rather than considering individuals experiences of engaging with such change. This paper aims to review the qualitative research on individuals' experience of proposed dietary modifications with a weight loss focus. Six databases were searched for qualitative and mixed-methods research studies, and studies were subject to analysis following Thomas and Hardin's guidelines. The search yielded 2945 results, of which 47 were reviewed in full, and nine were included for analysis. Four analytical themes were identified; variability in support; choosing dietary change; re-negotiating the food relationship; and looking beyond weight loss. Providing tailored nutritional information that is comprehensible and culturally appropriate must be the premise of the interventions offered. Supporting patients to understand their relationship with food and identify meaningful goals beyond weight loss is an important starting point.

Barriers and facilitators to self-management of chronic conditions reported by women: a systematic review of qualitative studies

OBJECTIVES

This systematic review aims to identify, appraise and synthesise the findings of published qualitative research exploring the barriers and facilitators to self-management of chronic conditions reported by women.

DESIGN

A systematic literature review and thematic synthesis of qualitative studies.

DATA SOURCES

A search of MEDLINE, CINAHL, Embase and PsycInfo was undertaken using the search terms 'Women', 'Woman' 'Female,' 'Chronic', 'Long-term', 'Disease', 'Illness', 'Condition' 'Health,' 'Self-management,' 'Qualitative,' 'Barrier' and 'Facilitator'. A hand search for literature was also performed.

ELIGIBILITY CRITERIA

Studies published before 2005 and those not in English were excluded.

DATA EXTRACTION AND SYNTHESIS

Extracted data were analysed thematically and emerging and recurring themes identified. Themes were mapped to the six components of the COM-B model. Critical appraisal of included publications was undertaken using the CASP (Critical Appraisal Skills Programme) qualitative checklist and finding weighted on quality.

RESULTS

Eighty-four publications were identified and eligible for inclusion within the review. Studies were conducted in five continents, with a focus on 20 different chronic conditions and included a total of 1788 women. Barriers and facilitators to physical capability, psychological capability, physical opportunity, social opportunity, autonomic motivation and reflective motivation were identified with a number of recurring themes found. Self-prioritisation, support and culture all had a significant impact on whether women followed self-management recommendations. Certain groups of women such as those living remotely, those with financial difficulties, migrants and those who do not speak the predominant language appear to face additional barriers to self-management.

CONCLUSIONS

This review highlights that to self-manage chronic conditions women have to overcome various cultural, financial and social barriers. Self-management programmes should be designed taking into account these factors in order to ensure women are better supported and enabled to improve their health outcomes.

Healthy Eating and Active Lifestyles for Diabetes (HEAL-D) Online: a mixed methods evaluation exploring the feasibility of implementing a virtual culturally tailored diabetes self-management programme for African and Caribbean communities

OBJECTIVES

To assess the feasibility and acceptability of delivering Healthy Eating and Active Lifestyles for Diabetes (HEAL-D) Online.

INTERVENTION

HEAL-D Online-a 7-week culturally tailored type 2 diabetes educational programme delivered using online platform.

SETTING

Programme delivered by a London NHS trust, with patients referred from primary care healthcare professionals via a central booking system.

PARTICIPANTS

53 HEAL-D service users completed a postcourse questionnaire, and 14 service users and 7 service delivery staff participated in interviews.

DESIGN

Mixed methods service evaluation.

PRIMARY AND SECONDARY OUTCOMES

Service user engagement, acceptability and perceived patient benefit assessed using service activity data. Feasibility and acceptability of HEAL-D Online, using semi-structured interviews to explore the views and experiences of service users and service delivery staff.

RESULTS

Service activity data showed that initial uptake of HEAL-D Online was good (62% attendance) with a high adherence to the programme (77% completion). A high fidelity (94%) was observed, and qualitative findings showed that staff and service users were satisfied with all aspects of course delivery. Both service activity and qualitative data indicated that attendees felt more confident in controlling their diet and managing their diabetes post-HEAL-D Online.

CONCLUSION

This evaluation demonstrates the feasibility of delivering HEAL-D using an online platform, with its ability to achieve similar goals compared with its face-to-face counterpart. Challenges were identified around the identification, recruitment and referral of eligible patients into the programme, which need to be addressed for successful implementation on a wider scale.

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.

Barriers and facilitators of lifestyle management among adult South Asian migrants living with chronic diseases: A mixed-methods systematic review

BACKGROUND AND AIM

South Asian migrants have a higher prevalence of chronic diseases than Caucasians. Despite much literature that has explored challenges in chronic disease management amongst the South Asian population in the past decades, their chronic disease management is still suboptimal. Understanding their determinants of disease management behaviour using the Theoretical Domains Framework will inform the development of a culturally sensitive intervention relevant to consumer-end-users. This study aimed to synthesise qualitative and quantitative studies on chronic disease management among adult South Asian immigrants.

METHODS

A mixed-methods systematic review was conducted using electronic databases. The Mixed Methods Appraisal Tool assessed the quality of the included studies. Quantitative data were transformed into qualitative data and analysed thematically. Subthemes were mapped in the Theoretical Domains Framework presenting barriers and facilitators under each theme.

RESULTS

18293 studies were identified, of which 37 studies were included. The barriers and facilitators identified were categorised into four overarching themes: patient-provider interaction and relationship (e.g., complex language use by health professionals), the impact of migration (e.g., weather conditions had an impact on engagement with physical activity), heritage-based practices (e.g., an obligation to consume energy-dense food in social gatherings), and chronic disease management strategies (e.g., lack understanding of appropriate disease management strategies).

CONCLUSION

This review provides a comprehensive understanding of the complexity of chronic disease management among South Asian migrants and insights into developing multifaceted interventions to address barriers to chronic disease management, guiding the healthcare professionals in helping overcome South Asians perceived barriers to managing chronic disease in the host countries.

Patient engagement as a core element of translating clinical evidence into practice- application of the COM-B model behaviour change model

BACKGROUND

The results of rehabilitation trials are often not fully attained when the intervention is implemented beyond the initial trial. One of the key reasons is that a patients' ability and/or capacity to take part in their own healthcare is not considered in the trial design yet has significant impact on the outcomes during the implementation phase.

BODY OF TEXT

We propose a shift from a therapist-focus to patient-focus in trial design, through addressing patient engagement as a core consideration in trials. We argue that engaging patients in any rehabilitation program is a process of behavioural change. Exercise prescription is used as an example to illustrate how the Behaviour Change Wheel can be applied to analyse barriers and facilitators associated with patients' capabilities, opportunities and motivations in integrating trial interventions into their daily life. We propose a framework to assist in this shift.

CONCLUSION

A core part of implementing rehabilitation interventions at the primary care level requires patient engagement. Related aspects of interventions should be identified and assessed using the COM-B model at the outset of trial design to ensure that the results are realistic, meaningful and transferable, so as to enable real impact.

Improving adult behavioural weight management services for diverse UK Black Caribbean and Black African ethnic groups: a qualitative study of insights from potential service users and service providers

Background

A significantly higher proportion of UK Black ethnic adults live with overweight or obesity, compared to their White British counterparts. The role of obesity in excess infection rates and mortality from COVID-19 has increased the need to understand if weight management interventions are appropriate and effective for Black ethnic groups. There is a paucity of existing research on weight management services in Black populations, and whether anticipated or experienced institutional and interpersonal racism in the healthcare and more widely affects engagement in these services. Understanding the lived experience of target populations and views of service providers delivering programmes is essential for timely service improvement.

Methods

A qualitative study using semi-structured interviews was conducted in June-October 2021 among 18 Black African and Black Caribbean men and women interested in losing weight and 10 weight management service providers.

Results

The results highlighted a positive view of life in the United Kingdom (UK), whether born in the UK or born abroad, but one which was marred by racism. Weight gain was attributed by participants to unhealthy behaviours and the environment, with improving appearance and preventing ill health key motivators for weight loss. Participants relied on self-help to address their overweight, with the role of primary care in weight management contested as a source of support. Anticipated or previously experienced racism in the health care system and more widely, accounted for some of the lack of engagement with services. Participants and service providers agreed on the lack of relevance of existing services to Black populations, including limited culturally tailored resources. Community based, ethnically matched, and flexibly delivered weight management services were suggested as ideal, and could form the basis of a set of recommendations for research and practice.

Conclusion

Cultural tailoring of existing services and new programmes, and cultural competency training are needed. These actions are required within systemic changes, such as interventions to address discrimination. Our qualitative insights form the basis for advancing further work and research to improve existing services to address the weight-related inequality faced by UK Black ethnic groups.

Co-designing nutrition interventions with consumers: A scoping review

BACKGROUND

There is little known about nutrition intervention research involving consumer co-design. The aim of this scoping review was to identify and synthesise the existing evidence on the current use and extent of consumer co-design in nutrition interventions.

METHODS

This scoping review is in line with the methodological framework developed by Arksey and O'Malley and refined by the Joanna Briggs Institute using an adapted 2weekSR approach. We searched Medline, EMBASE, PsycInfo, CINAHL and Cochrane. Only studies that included consumers in the co-design and met the 'Collaborate' or 'Empower' levels of the International Association of Public Participation's Public Participation Spectrum were included. Studies were synthesised according to two main concepts: (1) co-design for (2) nutrition interventions.

RESULTS

The initial search yielded 8157 articles, of which 19 studies were included (comprising 29 articles). The studies represented a range of intervention types and participants from seven countries. Sixteen studies were published in the past 5 years. Co-design was most often used for intervention development, and only two studies reported a partnership with consumers across all stages of research. Overall, consumer involvement was not well documented. No preferred co-design framework or approach was reported across the various studies.

CONCLUSIONS

Consumer co-design for nutrition interventions has become more frequent in recent years, but genuine partnerships with consumers across all stages of nutrition intervention research remain uncommon. There is an opportunity to improve the reporting of consumer involvement in co-design and enable equal partnerships with consumers in nutrition research.

Using the COM-B model and Behaviour Change Wheel to develop a theory and evidence-based intervention for women with gestational diabetes (IINDIAGO)

BACKGROUND

In South Africa, the prevalence of gestational diabetes (GDM) is growing, concomitant with the dramatically increasing prevalence of overweight/obesity among women. There is an urgent need to develop tailored interventions to support women with GDM to mitigate pregnancy risks and to prevent progression to type 2 diabetes post-partum. The IINDIAGO study aims to develop and evaluate an intervention for disadvantaged GDM women attending three large, public-sector hospitals for antenatal care in Cape Town and Soweto, SA. This paper offers a detailed description of the development of a theory-based behaviour change intervention, prior to its preliminary testing for feasibility and efficacy in the health system.

METHODS

The Behaviour Change Wheel (BCW) and the COM-B model of behaviour change were used to guide the development of the IINDIAGO intervention. This framework provides a systematic, step-by-step process, starting with a behavioural analysis of the problem and making a diagnosis of what needs to change, and then linking this to intervention functions and behaviour change techniques to bring about the desired result. Findings from primary formative research with women with GDM and healthcare providers were a key source of information for this process.

RESULTS

Key objectives of our planned intervention were 1) to address women's evident need for information and psychosocial support by positioning peer counsellors and a diabetes nurse in the GDM antenatal clinic, and 2) to offer accessible and convenient post-partum screening and counselling for sustained behaviour change among women with GDM by integrating follow-up into the routine immunisation programme at the Well Baby clinic. The peer counsellors and the diabetes nurse were trained in patient-centred, motivational counselling methods.

CONCLUSIONS

This paper offers a rich description and analysis of designing a complex intervention tailored to the challenging contexts of urban South Africa. The BCW was a valuable tool to use in designing our intervention and tailoring its content and format to our target population and local setting. It provided a robust and transparent theoretical foundation on which to develop our intervention, assisted us in making the hypothesised pathways for behaviour change explicit and enabled us to describe the intervention in standardised, precisely defined terms. Using such tools can contribute to improving rigour in the design of behavioural change interventions.

Intervention development of 'Diabetes Together' using the person-based approach: a couples-focused intervention to support self-management of type 2 diabetes in South Africa

OBJECTIVES

Type 2 diabetes (T2D) is a growing concern in South Africa, where many find self-management challenging. Behaviour-change health interventions are enhanced by involving partners of patients. We aimed to develop a couples-focused intervention to improve self-management of T2D among adults in South Africa.

DESIGN

We used the person-based approach (PBA): synthesising evidence from existing interventions; background research; theory; and primary qualitative interviews with 10 couples to ascertain barriers and facilitators to self-management. This evidence was used to formulate guiding principles that directed the intervention design. We then prototyped the intervention workshop material, shared it with our public and patient involvement group and ran iterative co-discovery think-aloud sessions with nine couples. Feedback was rapidly analysed and changes formulated to improve the intervention, optimising its acceptability and maximising its potential efficacy.

SETTING

We recruited couples using public-sector health services in the area of Cape Town, South Africa, during 2020-2021.

PARTICIPANTS

The 38 participants were couples where one person had T2D.

INTERVENTION

We developed the 'Diabetes Together' intervention to support self-management of T2D among couples in South Africa, focussing on: improved communication and shared appraisal of T2D; identifying opportunities for better self-management; and support from partners. Diabetes Together combined eight informational and two skills-building sections over two workshops.

RESULTS

Our guiding principles included: providing equal information on T2D to partners; improving couples' communication; shared goal-setting; discussion of diabetes fears; discussing couples' roles in diabetes self-management; and supporting couples' autonomy to identify and prioritise diabetes self-management strategies.Participants viewing Diabetes Together valued the couples-focus of the intervention, especially communication. Feedback resulted in several improvements throughout the intervention, for example, addressing health concerns and tailoring to the setting.

CONCLUSIONS

Using the PBA, our intervention was developed and tailored to our target audience. Our next step is to pilot the workshops' feasibility and acceptability.

HbA1c screening for diabetes mellitus and to evaluate diabetic control in people of African ancestry with HIV in South London

We evaluated glycaemic status in 948 Black adults with HIV and report a high prevalence of dysglycaemia (37.2%). HbA1c testing identified 38 (4.0%) individuals not previously known to have diabetes mellitus (DM) and showed suboptimal or poor glycaemic control in more than half of those with a prior DM diagnosis despite high levels of HIV control.

Developing a Suite of Resources to Improve Patient Adherence to Compression Stockings: Application of Behavior Change Theory

PURPOSE

Poor patient adherence to compression stockings remains a difficult and pervasive problem for clinicians, with costly repercussions for patients and health-care systems. The purpose of this paper was to describe the application of behavior change theory to the systematic development of a suite of resources, aimed at improving patient adherence to wearing compression stockings.

METHODS

Employing a non-empirical approach, behavior-change theory was used to develop an innovative intervention as part of a multi-phase project. Target behaviors, barriers and potential enablers were identified in relation to stocking adherence. An impact-likelihood matrix for behavior prioritization was used to identify possible areas for intervention within occupational therapy outpatient clinics. Selection of suitable resources and their consequent development were based on a narrative and problem-solving process by a panel of clinical experts.

RESULTS

Of 14 potential domains embedded in the Theoretical Domains Framework, the key target behaviors and barriers were associated with eight domains. Michie's Behavior Change Wheel revealed recommendations in six subdivisions and of these, four intervention functions were selected by the panel, based on their potential impact and likelihood of adoption in clinical practice. Findings led to the development of a suite of resources comprising a new questionnaire, a clinical decision tree, augmented by clinical answer sheets corresponding to each of the barriers.

CONCLUSION

Application of behavior change theory informed the design of a behavior change intervention comprising an integrated suite of resources for novice and experienced clinicians.

PRACTICE IMPLICATIONS

These novel resources have potential to improve patient adherence to compression stockings and consequently generate health-care savings through reduced need for wound care products, and medical interventions with translation to other settings and conditions requiring compression stockings. Patient outcomes will likely be improved with reduced pain, improved quality of life and earlier resumption of usual occupations.

A Systematic Review of Internet-Based Interventions for the Prevention and Self-Management of Cardiovascular Diseases among People of African Descent

Cardiovascular disease (CVD) risk factors, morbidity, and mortality among people of African descent (PAD) appear to be higher than in the general population. While it has been found that lifestyle changes can prevent around 90% of CVDs, implementing an effective lifestyle programme is expensive and time-consuming. It has been demonstrated that Internet-based interventions (IbIs) can effectively and inexpensively encourage lifestyle modifications to prevent and manage chronic diseases. Although a number of studies have examined the effectiveness of IbIs in the general population, no comprehensive study of the usefulness and acceptability of IbIs among PAD has been conducted. This is the knowledge gap that this study aimed to address. We searched MEDLINE, EMBASE, CINAHL, and Web of Science to identify eligible studies published from inception to February 2022. Thirteen articles met our criteria for inclusion. Our textual narrative synthesis produced inconsistent results; nonetheless, high acceptability of IbIs and a considerable improvement in clinical and behavioural outcomes associated with CVDs were reported in several trials. The findings of this review are constrained by clinical, methodological and statistical variability among the studies. To have a good grasp on the effect of IbIs on behaviour change in PAD at risk of CVDs, large-scale longitudinal studies with long-term follow-up are required.

Group-based nutrition interventions to promote healthy eating and mobility in community-dwelling older adults: a systematic review

OBJECTIVE

To identify the efficacy of group-based nutrition interventions to increase healthy eating, reduce nutrition risk, improve nutritional status and improve physical mobility among community-dwelling older adults.

DESIGN

Systematic review. Electronic databases MEDLINE, CINAHL, EMBASE, PsycINFO and Sociological Abstracts were searched on July 15, 2020 for studies published in English since January 2010. Study selection, critical appraisal (using the Joanna Briggs Institute's tools) and data extraction were performed in duplicate by two independent reviewers.

SETTING

Nutrition interventions delivered to groups in community-based settings were eligible. Studies delivered in acute or long-term care settings were excluded.

PARTICIPANTS

Community-dwelling older adults aged 55+ years. Studies targeting specific disease populations or promoting weight loss were excluded.

RESULTS

Thirty-one experimental and quasi-experimental studies with generally unclear to high risk of bias were included. Interventions included nutrition education with behaviour change techniques (BCT) (e.g. goal setting, interactive cooking demonstrations) (n 21), didactic nutrition education (n 4), interactive nutrition education (n 2), food access (n 2) and nutrition education with BCT and food access (n 2). Group-based nutrition education with BCT demonstrated the most promise in improving food and fluid intake, nutritional status and healthy eating knowledge compared with baseline or control. The impact on mobility outcomes was unclear.

CONCLUSIONS

Group-based nutrition education with BCT demonstrated the most promise for improving healthy eating among community-dwelling older adults. Our findings should be interpreted with caution related to generally low certainty, unclear to high risk of bias and high heterogeneity across interventions and outcomes. Higher quality research in group-based nutrition education for older adults is needed.

Design of a Planner-Based Intervention to Facilitate Diet Behaviour Change in Type 2 Diabetes

Diet behaviour is influenced by the interplay of the physical and social environment as well as macro-level and individual factors. In this study, we focus on diet behaviour at an individual level and describe the design of a behaviour change artefact to support diet behaviour change in persons with type 2 diabetes. This artefact was designed using a human-centred design methodology and the Behaviour Change Wheel framework. The designed artefact sought to support diet behaviour change through the addition of healthy foods and the reduction or removal of unhealthy foods over a 12-week period. These targeted behaviours were supported by the enabling behaviours of water consumption and mindfulness practice. The artefact created was a behaviour change planner in calendar format, that incorporated behaviour change techniques and which focused on changing diet behaviour gradually over the 12-week period. The behaviour change planner forms part of a behaviour change intervention which also includes a preparatory workbook exercise and one-to-one action planning sessions and can be customised for each participant.

Identifying the factors affecting 'patient engagement' in exercise rehabilitation

Background

Despite the proven benefits of exercise rehabilitation for numerous health conditions, musculoskeletal injuries and recovery from surgery, patient adherence to such programs is reported to often be less than 35%. Increasing patient engagement therefore has the potential to improve patient health outcomes, benefiting the patient, their carers and the services that support them. The aims of this review were to identify the factors that contribute to ‘patient’ engagement in prescribed exercise rehabilitation using the COM-B (capability, opportunity, motivation-behaviour) framework of behavioural analysis.

Methods

Five electronic databases (PubMed, Embase, Cochrane, Web of Science, and ClinicalTrials.gov) were searched. ‘COM-B’ was the key word searched for specifically within titles and abstracts, combined with either ‘physical activity’ OR ‘exercise’ included using the ‘AND’ operation. Records were then filtered and excluded following full-text screening based on the predetermined eligibility criteria.

Results

Twenty studies were included in the review. The main COM-B themes highlighted for improving patient engagement were: capability—improving patient knowledge and cognitive skills for behavioural regulation, such as ‘action planning’ and ‘action control’, which could also benefit time-management; opportunity—a balanced life situation that enabled time to be devoted to the exercise program, social support, easily accessible and affordable resources and services; and motivation—increasing patient levels of self-efficacy and autonomous motivation, which were noted to be influenced by levels of perceived ‘capability’, additionally ‘motivation’ was noted to be influenced by patients perceiving the benefits of the exercise, and adherence to the program was promoted by ‘goal-setting’. Other issues in the ‘capability’ domain included a fear and/or dislike of exercise.

Conclusion

Patient engagement behavior has been shown to be influenced by both external (opportunity) and intrapersonal variables (capability and motivation). Those prescribing exercises within a rehabilitation program need to discuss these factors with their patients and co-design the exercise rehabilitation program in partnership with the patient, since this is likely to improve patient engagement, and thereby result in superior health outcomes. Furthermore, these factors need to be a consideration in clinical trials, if the findings from such trials are to translate into mainstream healthcare settings.

Exploring the experiences of people and family carers from under-represented groups in self-managing Parkinson's disease and their use of digital health to do this

Introduction

Digital health is thought to enable people to better manage chronic conditions, such as Parkinson's. However, little is known about how people from under-represented groups with chronic conditions use digital health to self-manage.

Objective

The objective of our study was to explore the experiences of people and family carers from under-represented groups in self-managing Parkinson's, including their use of digital health to do this.

Methods

Semi-structured interviews (n = 18, including four dyadic) were conducted remotely, with 16 people with Parkinson's and six family carers in 2020–2021. Participants were purposively sampled from under-represented groups: belong to an ethnic minority, or having significant physical or sensory impairment. Interviews were audio-recorded, transcribed and analysed using thematic analysis.

Results

Three main themes of importance were developed: ‘self-management support’, ‘digital health use to support self-management’ and ‘identity, attitudes and characteristics’. Participants received medical, psychological, social and practical self-management support. Some participants used digital health resources, e.g., Parkinson's UK website. Digital literacy was the biggest barrier to using digital health, regardless of background, often dependant on previous occupation and confidence. Few ethnic minority participants thought race or culture alters self-management ability and most believed there was no need for digital health interventions to be tailored to an individual's race or culture. Some felt inclusivity was important in terms of diverse images of people. A range of considerations were identified to optimise digital health, such as assistive equipment for people with sensory impairment.

Conclusions

Barriers to using digital health for self-management were primarily dependent on personal factors including digital literacy and attitudes but rarely race or culture. We recommend the optimisation of digital health interventions by providing assistive technology at low cost, and visual inclusiveness should be promoted by including images of people from diverse backgrounds.

Development of Healthy Eating and Active Lifestyles for Diabetes, a culturally tailored diabetes self-management education and support programme for Black-British adults: A participatory research approach

AIMS

To develop an evidence-based, culturally tailored, diabetes self-management education and support programme for Black-British adults, called Healthy Eating and Active Lifestyles for Diabetes (HEAL-D), using participatory methods to engage key stakeholders in the intervention design process.

METHODS

Black-British adults living with type 2 diabetes, healthcare professionals and community leaders were engaged in an intervention development study. The intervention structure, format, content and delivery were developed through three phases of participatory research: Phase 1, formative research, involved focus groups and interviews; interactive co-development workshops were conducted in Phase 2; and Phase 3 focused on materials development.

RESULTS

In Phase 1, focus groups and interviews identified the importance of nurturing collectivism, a reliance on informal sources of information/advice, barriers to attending appointments associated with competing priorities of work, travel and carer commitments, and a preference for directness and simple, clear advice/messages. A priority for healthcare professionals was the intervention embedding within current primary care structures and aligning with incentivised targets/metrics. Phase 2 (workshops) highlighted key requirements: avoidance of medical settings, appropriately trained and culturally knowledgeable educators, flexible appointments, preference for verbal and visual information and avoidance of technical/medical terminology. In Phase 3 (materials development), culturally sensitive videos, short films and information booklets were developed to convey educational messages, and food photography was used to provide culturally relevant dietary advice.

CONCLUSIONS

Participatory methods provide a means to understand the needs of specific communities. This approach enables the development of healthcare interventions that are sensitive to the needs of service users and providers.

Healthy Eating and Active Lifestyles for Diabetes (HEAL-D), a culturally tailored self-management education and support program for type 2 diabetes in black-British adults: a randomized controlled feasibility trial

INTRODUCTION

Black-British communities are disproportionately affected by type 2 diabetes (T2D). Structured education programs are a core component of T2D healthcare but they are less successful in people from minority ethnic groups. Culturally tailored T2D education has demonstrated greater benefits than usual care. The aim of our study was to evaluate acceptability, fidelity and trial feasibility of the Healthy Eating and Active Lifestyles for Diabetes ('HEAL-D') culturally tailored T2D self-management education and support (DSMES) program.

RESEARCH DESIGN AND METHODS

A mixed-methods randomized controlled feasibility trial in black-British adults with T2D was conducted. Participants were assigned to control (usual care) or intervention (HEAL-D; 7 sessions, 14 hours of group-based culturally tailored diet and lifestyle education, behavior change support and supervised physical activity), in a ratio of 1:1. Primary outcomes were recruitment and retention rates, intervention attendance and completion. Fidelity was assessed through observations and qualitative evaluation was undertaken with participants and educators.

RESULTS

102 patients responded to invitation letters (n=1335); 63 were randomized but 8 were subsequently deemed ineligible due to high baseline glycosylated hemoglogin (HbA1c) requiring intensive medical management or missing baseline HbA1c measurement. Of the remaining 55 participants (27 intervention, 28 control), 69% were female, 47% were of African and 51% were of Caribbean ethnicity. 93% completed the trial, providing end point data. Intervention attendance was high; 85% completed the program (attendance at ≥5 sessions), and 74% attended ≥6 sessions. The intervention was delivered with acceptable fidelity, although the qualitative evaluations identified some areas of structure and format in need of refinement.

CONCLUSIONS

We have shown it is feasible to recruit and randomize black-British adults with T2D to a trial of a culturally tailored DSMES program. We have shown the intervention is highly acceptable for both patients and healthcare providers. A future trial should assess clinical and cost-effectiveness of HEAL-D.

Contextually Appropriate Tools and Solutions to Facilitate Healthy Eating Identified by People with Type 2 Diabetes

Type 2 diabetes (T2D) is a complex, multifaceted disease and its treatment involves lifestyle intervention (LI) programs that participants may find difficult to adopt and maintain. The objective of this study is to understand the lived experiences of participants with T2D regarding healthy eating behavior change, in order to identify and incorporate relevant information, skills, and educational approaches into LI programs. An explorative qualitative study was undertaken. Purposeful sampling was used to recruit 15 participants. One-on-one, semi-structured, open-ended, and in-depth interviews were conducted. An essentialist paradigm was adopted to accurately report the experiences, meaning, and reality of participants. An inductive approach was used to analyze the data. Participants reported that being diagnosed and living with T2D could be overwhelming, and their ability to manage was influenced by health care providers (HCP), family, and individual context. Many experienced a loop of "good-bad" eating behaviors. Participants expressed desires for future diabetes management that would include program content (nutrition, physical activity, mental health, foot care, and consequences of T2D), program features (understand context, explicit information, individualized, hands-on learning, applicable, realistic, incremental, and practical), program components (access to multidisciplinary team, set goals, track progress and be held accountable, one-on-one sessions, group support, maintenance/follow-up), and policy change. In conclusion, the results of this study indicate that T2D management requires more extensive, comprehensive, and ongoing support, guided by the individual participant.

Factors Influencing Pregnancy and Postpartum Weight Management in Women of African and Caribbean Ancestry Living in High Income Countries: Systematic Review and Evidence Synthesis Using a Behavioral Change Theoretical Model

Background: Women of black African heritage living in high income countries (HIC) are at risk of obesity and weight-related complications in pregnancy. This review aimed to synthesize evidence concerning attitudes to weight management-related health behaviors in pregnancy and postpartum, in women of black African ancestry, living in high-income countries. Methods: A systematic review of the literature and thematic evidence synthesis using the Capability-Opportunity-Motivation Behavioral change theoretical model (COM-B). Databases searched included MEDLINE, EMBASE, Web of Science, and Scopus. The CASP tool was used to assess quality. Results: Twenty-four papers met the selection criteria, most of which were from the US. Motivational factors were most commonly described as influencers on behavior. Normative beliefs about "eating for two," weight gain being good for the baby, the baby itself driving food choice, as well as safety concerns about exercising in pregnancy, were evident and were perpetuated by significant others. These and other social norms, including a cultural acceptance of larger body shapes, and daily fast food, created a challenge for healthy behavior change. Women also had low confidence in their ability to lose weight in the postpartum period. Behavior change techniques, such as provision of social support, use of credible sources, and demonstration may be useful to support change. Conclusions: The women face a range of barriers to engagement in weight-related health behaviors at this life-stage. Using a theoretical behavior change framework can help identify contextual factors that may limit or support behavior change.

Motiva.DM2 project. A pilot behavioral intervention on diet and exercise for individuals with type 2 diabetes mellitus

AIM

The purpose of this study was to assess the efficacy of an educational intervention based on the Behavior Change Wheel (BCW) framework for individuals with type 2 diabetes mellitus (DM2) on dietary and exercise behavior in a Spanish region.

METHODS

A two-arm pilot research was developed. The intervention consisted of a 6-month period with guidelines and 4 in-person interventions. The outcome was changes in behaviors, motivation, competence, autonomy, social support to implement the recommendations, HbA1c, and body composition.

RESULTS

n = 111 patients were recruited. Individuals in the intervention experienced a significative improvement on adherence to dietary recommendations (+1.23; p = 0.026), exercise (+0.86; p = 0.001), and a decrease in HbA1c levels (-0.6%; p = 0.002) and BMI (-0.73; p < 0.001).

CONCLUSION

The intervention for DM2 individuals, based on the BCW framework, developed, and implemented by primary care nurses has been effective in improving the adherence to healthy eating, exercise, HbA1c levels, and body composition.

Behaviour change in diabetes: behavioural science advancements to support the use of theory

Behaviour is central to the management of diabetes, both for people living with diabetes and for healthcare professionals delivering evidence-based care. This review outlines the evolution of behavioural science and the application of theoretical models in diabetes care over the past 25 years. There has been a particular advancement in the development of tools and techniques to support researchers, healthcare professionals and policymakers in taking a theory-based approach, and to enhance the development, reporting and replication of successful interventions. Systematic guidance, theoretical frameworks and lists of behavioural techniques provide the tools to specify target behaviours, identify why ideal behaviours are not implemented, systematically develop theory-based interventions, describe intervention content using shared terminology, and evaluate their effects. Several examples from a range of diabetes-related behaviours (clinic attendance, self-monitoring of blood glucose, retinal screening, setting collaborative goals in diabetes) and populations (people with type 1 and type 2 diabetes, healthcare professionals) illustrate the potential for these approaches to be widely translated into diabetes care. The behavioural science approaches outlined in this review give healthcare professionals, researchers and policymakers the tools to deliver care and design interventions with an evidence-based understanding of behaviour. The challenge for the next 25 years is to refine the tools to increase their use and advocate for the role of theoretical models and behavioural science in the commissioning, funding and delivery of diabetes care.
