Transferability of the NHS low-calorie diet programme: A qualitative exploration of factors influencing the programme's transfer ahead of wide-scale adoption.

INTRODUCTION: Although behavioural interventions have been found to help control type 2 diabetes (T2D), it is important to understand how the delivery context can influence implementation and outcomes. The NHS committed to testing a low-calorie diet (LCD) programme designed to support people living with excess weight and T2D to lose weight and improve diabetes outcomes. Understanding what influenced implementation during the programme pilot is important in optimising rollout. This study explored the transferability of the NHS LCD Programme prior to wider adoption. METHODS: Twenty-five interviews were undertaken with stakeholders involved in implementing the LCD programme in pilot sites (health service leads, referring health professionals and programme deliverers). Interviews with programme participants (people living with T2D) were undertaken within a larger programme of work, exploring what worked, for whom and why, which is reported separately. The conceptual Population-Intervention-Environment-Transfer Model of Transferability (PIET-T) guided study design and data collection. Constructs of the model were also used as a deductive coding frame during data analysis. Key themes were identified which informed recommendations to optimise programme transfer. RESULTS: Population: Referral strategies in some areas lacked consideration of population characteristics. Many believed that offering a choice of delivery model would promote acceptability and accessibility of the eligible population. INTERVENTION: Overall, stakeholders had confidence in the LCD programme due to the robust evidence base along with anecdotal evidence, but some felt the complex referral process hindered engagement from GP practices. ENVIRONMENT: Stakeholders described barriers to accessing the programme, including language and learning difficulties. Transferability: Multidisciplinary working and effective communication supported successful implementation. CONCLUSION: Referral strategies to reach underrepresented groups should be considered during programme transfer, along with timely data from service providers on access and programme benefits. A choice of delivery models may optimise uptake. Knowledge sharing between sites on good working practices is encouraged, including increasing engagement with key stakeholders.

A Qualitative evaluation in community settings in England exploring the experiences of coaches delivering the NHS Low Calorie Diet programme pilot to ethnically diverse participants.

BACKGROUND: The management of type 2 diabetes (T2D) within diverse ethnic populations requires a culturally tailored approach. However, little is known about the experiences of coaches delivering interventions for T2D, such as the National Health Service (NHS) Low Calorie Diet (LCD) programme, to people from diverse ethnic backgrounds. OBJECTIVE: To explore the experiences of coaches delivering an NHS programme using total diet replacement approaches to individuals from diverse ethnic backgrounds, to inform the effective tailoring and equitable delivery of future interventions. DESIGN: Qualitative study. SETTING: Individuals delivering the NHS LCD programme. PARTICIPANTS: One-to-one semistructured interviews were conducted with seven health coaches delivering the NHS LCD programme. Inclusion criteria included participants delivering the NHS LCD programme either from a minoritised ethnic background or delivering the programme to those from ethnic minority and white British backgrounds. MAIN OUTCOME MEASURES: Qualitative semistructured interviews conducted through different stages of the programme. Reflexive thematic analysis was used to analyse the transcripts. RESULTS: Key themes highlighted the following experiences of delivering the LCD programme: (1) training and support needs; (2) needing to understand culture and ethnicity; (3) the impact of language; (4) the use of resources in providing dietary advice and (5) experiences of cultural tailoring. The themes highlight the need to prioritise person-centred care, to integrate culturally tailored approaches and for provision of education and training to those delivering health programmes. CONCLUSION: These findings describe the experiences of health coaches in tailoring delivery and emphasise the role of cultural competence in ensuring equitable and effective healthcare interventions for diverse populations. This learning can inform future programmes and policies aimed at promoting inclusive healthcare practices.

The NHS Low-Calorie Diet Digital Programme: Fidelity of behaviour change technique delivery.

AIMS: NHS England commissioned independent service providers to deliver the NHS Low-Calorie Diet Programme pilot. Previous research has illustrated a drift in the fidelity of behaviour change techniques (BCTs) during the delivery of the programme provided through face-to-face group or one-to-one behavioural support. The aim of this study was to assess the delivery fidelity of the BCT content in the digital delivery of the programme. METHODS: Online, app chat and phone call support content was coded using The Behaviour Change Technique Taxonomy. BCTs delivered by each service provider (N = 2) were calculated and compared to the BCTs specified in the NHS service specification and those specified in the providers' programme plans. RESULTS: Between 78% and 83% of the BCTs identified in the NHS service specification were delivered by the service providers. The fidelity of BCT delivery to those specified in providers' programme plans was 60%-65% for provider A, and 82% for provider B. CONCLUSIONS: The BCT content of the digital model used in the NHS-LCD programme adhered well to the NHS service specification and providers' plans. It surpassed what has been previously observed in face-to-face services provided through group or one-on-one behavioural support models.

Is the NHS low-calorie diet programme delivered as planned? An observational study examining adherence of intervention delivery to service specification.

Obesity and Type 2 Diabetes Mellitus (T2DM) are chronic conditions with significant personal, societal, and economic impacts. Expanding on existing trial evidence, the NHS piloted a 52-week low-calorie diet programme for T2DM, delivered by private providers using total diet replacement products and behaviour change support. This study aimed to determine the extent to which providers and coaches adhered to the service specification outlined by NHS England. An observational qualitative study was conducted to examine the delivery of both one-to-one and group-based delivery of programme sessions. Observations of 122 sessions across eight programme delivery samples and two service providers were completed. Adherence to the service specification was stronger for those outcomes that were easily measurable, such as weight and blood glucose, while less tangible elements of the specification, such as empowering service users, and person-centred delivery were less consistently observed. One-to-one sessions were more successful in their person-centred delivery, and the skills of the coaches delivering the sessions had a strong impact on adherence to the specification. Overall, the results show that there was variability by provider and delivery mode in the extent to which sessions of the NHS Low-Calorie Diet Programme reflected the intended service specification. In subsequent programmes it is recommended that one-to-one sessions are used, with accompanying peer support, and that providers improve standardised training and quality assurance to ensure specification adherence.

Pharmacological interventions for the management of children and adolescents living with obesity-An update of a Cochrane systematic review with meta-analyses.

IMPORTANCE: The effectiveness of anti-obesity medications for children and adolescents is unclear. OBJECTIVE: To update the evidence on the benefits and harms of anti-obesity medication. DATA SOURCES: Cochrane CENTRAL, MEDLINE, ClinicalTrials.gov and WHO ICTRP (1/1/16-17/3/23). STUDY SELECTION: Randomized controlled trials ≥6 months in people <19 years living with obesity. DATA EXTRACTION AND SYNTHESIS: Screening, data extraction and quality assessment conducted in duplicate, independently. MAIN OUTCOMES AND MEASURES: Body mass index (BMI): 95th percentile BMI, adverse events and quality of life. RESULTS: Thirty-five trials (N = 4331), follow-up: 6-24 months; age: 8.8-16.3 years; BMI: 26.2-41.7 kg/m2. Moderate certainty evidence demonstrated a -1.71 (95% confidence interval [CI]: -2.27 to -1.14)-unit BMI reduction, ranging from -0.8 to -5.9 units between individual drugs with semaglutide producing the largest reduction of -5.88 kg/m2 (95% CI: -6.99 to -4.77, N = 201). Drug type explained ~44% of heterogeneity. Low certainty evidence demonstrated reduction in 95th percentile BMI: -11.88 percentage points (95% CI: -18.43 to -5.30, N = 668). Serious adverse events and study discontinuation due to adverse events did not differ between medications and comparators, but medication dose adjustments were higher compared to comparator (10.6% vs 1.7%; RR = 3.74 [95% CI: 1.51 to 9.26], I2 = 15%), regardless of approval status. There was a trend towards improved quality of life. Evidence gaps exist for children, psychosocial outcomes, comorbidities and weight loss maintenance. CONCLUSIONS AND RELEVANCE: Anti-obesity medications in addition to behaviour change improve BMI but may require dose adjustment, with 1 in 100 adolescents experiencing a serious adverse event.

"For me, it is for longevity and making sure I am fit and around for my children": exploring motivations and barriers for weight management among minoritised communities in Medway, England.

BACKGROUND: Migration-related changes in dietary patterns and other structural and individual factors affect weight-related health practices of individuals migrating from low-and-middle-income to high-income countries. Thus, individuals of ethnically diverse backgrounds may be disproportionately affected by poorer health outcomes, including weight-related health issues. Understanding how this community could be supported to adopt weight-related healthy practices such as optimum dietary and exercise behaviour is an important issue for public health research. Against this backdrop, we explored structural and individual factors that facilitate and constrain the uptake of weight management services among members of minority ethnic communities in Medway, England. METHODS: Data were collected from audio-recorded interviews with 12 adult community members from minoritised ethnic communities using a semi-structured interview guide. Participants were recruited through a purposive and convenient sampling technique. Generated data were transcribed, coded into NVivo and analysed using the reflexive thematic analytical technique. RESULTS: Results showed that social support and health benefits of weight management were the main motivating factors for weight management among the study participants. Conversely, systemic barriers, family commitment and caring responsibilities, changes in dietary patterns post-migration and cultural norms were major factors constraining participants from adopting weight management behaviours. CONCLUSION: The results of this study indicate that structural and person-level factors serve as both facilitators and barriers to weight management among ethnically diverse communities in Medway, England. While our study is exploratory and opens doors for more studies among the population, we conclude that these minoritised communities could benefit from more equitable, tailored weight management programmes to support them in adopting weight-related practices.

Views, perceptions, and experiences of type 2 diabetes or weight management programs among minoritized ethnic groups living in high-income countries: A systematic review of qualitative evidence.

BACKGROUND: Prevalence of both obesity and type 2 diabetes can be higher in patients from certain ethnic groups, yet uptake and adherence to current support within these groups is lower, leading to widening health inequalities in high-income countries. OBJECTIVES: The main objective of this study is to understand the views, perceptions, and experiences of and barriers and facilitators in relation to the uptake and adherence to weight management and type 2 diabetes programs in minoritized ethnic groups in high-income countries. METHODS: CINAHL, MEDLINE, PsycINFO, Scopus, Academic Search Complete, and PubMed were searched for English language studies undertaken in community-dwelling adults residing in high-income countries, who are from a minoritized ethnic group within the country of study. RESULTS: Seventeen studies were synthesized using the JBI System for the Unified Management of the Assessment and Review of Information. From these studies, 115 findings were retrieved, and seven key themes were identified: (1) family health status and program education, (2) social support, (3) challenges, (4) cultural beliefs, (5) increased awareness and dietary changes, (6) impact of psychological evaluations, and (7) considerations for future. CONCLUSIONS: Nutritional considerations for type 2 diabetes mellitus and weight management programs in high-income countries should include social, habitual, economic, and conceptual components, which should include consideration of local ethnic and cultural norms and building community relationships while creating culturally tailored programs.

Commercial provider staff experiences of the NHS low calorie diet programme pilot: a qualitative exploration of key barriers and facilitators.

BACKGROUND: The National Health Service Type 2 Diabetes Path to Remission programme in England (known as the NHS Low Calorie Diet programme when piloted) was established to support people living with excess weight and Type 2 Diabetes to lose weight and improve their glycaemic control. A mixed method evaluation was commissioned to provide an enhanced understanding of the long-term cost effectiveness of the pilot programme, its implementation, equity and transferability across broad and diverse populations. This study provided key insights on implementation and equity from the service providers' perspective. METHODS: Thirteen focus groups were conducted with commercial providers of the programme, during the initial pilot rollout. Participants were purposively sampled across all provider organisations and staff roles involved in implementing and delivering the programme. Normalisation Process Theory (NPT) was used to design the topic schedule, with the addition of topics on equity and person-centredness. Data were thematically analysed using NPT constructs with additional inductively created codes. Codes were summarised, and analytical themes generated. RESULTS: The programme was found to fulfil the requirements for normalisation from the providers' perspective. However, barriers were identified in engaging GP practices and receiving sufficient referrals, as well as supporting service users through challenges to remain compliant. There was variation in communication and training between provider sites. Areas for learning and improvement included adapting systems and processes and closing the gap where needs of service users are not fully met. CONCLUSIONS: The evaluation of the pilot programme demonstrated that it was workable when supported by effective primary care engagement, comprehensive training, and effective internal and external communication. However, limitations were identified in relation to programme specifications e.g. eligibility criteria, service specification and local commissioning decisions e.g. pattern of roll out, incentivisation of general practice. A person-centred approach to care is fundamental and should include cultural adaptation(s), and the assessment and signposting to additional support and services where required.

Normalisation and equity of referral to the NHS Low Calorie Diet programme pilot; a qualitative evaluation of the experiences of health care staff.

BACKGROUND: Health and wellbeing can be profoundly impacted by both obesity and type 2 diabetes, while the normalisation and equity of care for people living with these non-communicable diseases remain as challenges for local health systems. The National Health Service Low Calorie Diet programme in England, aims to support people to achieve type 2 diabetes remission, while also reducing health inequalities. We have explored the experiences of health care staff who have made a referral to the LCD programme, while identifying effective and equitable delivery of programme referrals, and their normalisation into routine care. METHODS: Nineteen individual semi-structured interviews were completed health care staff in the first year of the Low Calorie Diet programme. Interviewees were purposively sampled from the ten localities who undertook the Low Calorie Diet programme pilot. Each interview explored a number of topics of interest including communication and training, referrals, equity, and demands on primary care, before being subjected to a thematic analysis. RESULTS: From the data, five core themes were identified: Covid-19 and the demands on primary care, the expertise and knowledge of referrers, patient identification and the referral process, barriers to referrals and who gets referred to the NHS LCD programme. Our findings demonstrate the variation in the real world settings of a national diabetes programme. It highlights the challenge of COVID-19 for health care staff, whereby the increased workload of referrals occurred at a time when capacity was curtailed. We have also identified several barriers to referral and have shown that referrals had not yet been normalised into routine care at the point of data collection. We also raise issues of equity in the referral process, as not all eligible people are informed about the programme. CONCLUSIONS: Referral generation had not yet been consistently normalised into routine care, yet our findings suggest that the LCD programme runs the risk of normalising an inequitable referral process. Inequalities remain a significant challenge, and the adoption of an equitable referral process, normalised at a service delivery level, has the capacity to contribute to the improvement of health inequalities.

The efficacy of sleep lifestyle interventions for the management of overweight or obesity in children: a systematic review and meta-analysis.

BACKGROUND: Childhood obesity remains a significant public health concern. Sleep duration and quality among children and youth are suboptimal worldwide. Accumulating evidence suggests an association between inadequate sleep and obesity risk, yet it is unclear whether this relationship is causal. This systematic review examines the efficacy of sleep interventions alone or as a part of lifestyle interventions for the management of overweight or obesity among children and adolescents. METHODS: A keyword/reference search was performed twice, in January 2021 and May 2022 in MEDLINE/PubMed, EMBASE/Ovid, PsycINFO/EBSCO, The Cochrane Library, Web of Science Core Collection/Web of Science, SciELO/Web of Science, and CINAHL/EBSCO. Study eligibility criteria included youth with overweight or obesity between 5 and 17, were RCTs or quasi-randomized, and focused on the treatment of overweight and obesity with a sleep behavior intervention component. Risk of bias was assessed using the Cochrane Risk of Bias assessment tool (RoB2). A Meta-analysis was conducted to estimate the effect of interventions with a sleep component on BMI. The study protocol was registered in PROSPERO (CRD42021233329). RESULTS: A total of 8 studies (2 quasi-experiments, 6 RCTs) met inclusion criteria and accounted for 2,231 participants across 7 countries. Only one study design isolated the effect of sleep in the intervention and reported statistically significant decreases in weight and waist circumference compared to control, though we rated it at high risk of bias. Our meta-analysis showed no significant overall effect on children's BMI as a result of participation in an intervention with a sleep component (Cohen's d = 0.18, 95% CI= -0.04, 0.40, Z = 1.56, P = .11), though caution is warranted due to substantial heterogeneity observed across studies (Tau2 = 0.08; X2 = 23.05, df = 7; I2 = 83.73%). CONCLUSIONS: There were mixed results on the effect of sleep interventions across included studies on BMI, other weight-related outcomes, diet, physical activity, and sleep. Except for one study at low risk of bias, three were rated as 'some concerns' and four 'high risk of bias'. Findings from this study highlight the need for additional RCTs isolating sleep as a component, focusing on children and adolescents living with overweight and obesity.

Associations between anxiety, depression, and weight status during and after pregnancy: A systematic review and meta-analysis.

Previous work has found adverse mental health symptomology in women living with obesity, compared with those of healthy weight, around the time of pregnancy. This meta-analysis aimed to explore the association between anxiety, depression, and weight status in women living with obesity before, during, and after pregnancy. Bibliographic databases were systematically searched, and 14 studies were included, which aimed to assess the association between excess weight and anxiety or depression outcomes in women before, during, or after pregnancy. Data were analyzed via narrative synthesis and random effects multi-level meta-analyses. Scores on mental health indices were significantly greater (indicative of worse anxiety/depression) in women with obesity compared to women of a healthy weight, around the time of pregnancy (SMD = 0.21 [95% CI: 0.11-0.31; 95% prediction intervals: 0.13-0.56], I2  = 73%, p < 0.01). Depressive symptoms were greater during and after pregnancy (SMD = 0.23 [95% CI: 0.13-0.34; 95% prediction intervals: -0.12 to 0.59], I2  = 75.0%, p < 0.01), and trait anxiety symptoms were greater during pregnancy (SMD = 0.24 [95% CI: 0.01-0.47; 95% prediction intervals: -0.25 to 0.72], I2  = 83.7%, p = 0.039) in women living with obesity, compared to those of healthy weight. Narrative evidence suggests that socioeconomic status and ethnicity may modify the relationship between obesity and mental health symptomology. The findings indicate that maternal obesity is associated with greater anxiety and depression symptoms. These findings may inform the design of maternal weight management interventions.

Can the delivery of behavioural support be improved in the NHS England Low-Calorie Diet Programme? An observational study of behaviour change techniques.

BACKGROUND: Previous research has illustrated a drift in the fidelity of behaviour change techniques (BCTs) during the design of the pilot NHS England Low-Calorie Diet (NHS-LCD) Programme. This study evaluated a subsequent domain of fidelity, intervention delivery. Two research questions were addressed: (1) To what extent were BCTs delivered with fidelity to providers programme plans? (2) What were the observed barriers and facilitators to delivery? METHODS: A mixed-methods sequential explanatory design was employed. Remote delivery of one-to-one and group-based programmes were observed. A BCT checklist was developed using the BCT Taxonomy v1; BCTs were coded as present, partially delivered, or absent during live sessions. Relational content analysis of field notes identified observed barriers and facilitators to fidelity. RESULTS: Observations of 122 sessions across eight samples and two service providers were completed. Delivery of the complete NHS-LCD was observed for five samples. Fidelity ranged from 33% to 70% across samples and was higher for group-based delivery models (64%) compared with one-to-one models (46%). Barriers and facilitators included alignment with the programme's target behaviours and outcomes, session content, time availability and management, group-based remote delivery, and deviation from the session plan. CONCLUSIONS: Overall, BCTs were delivered with low-to-moderate fidelity. Findings indicate a dilution in fidelity during the delivery of the NHS-LCD and variation in the fidelity of programmes delivered across England. Staff training could provide opportunities to practice the delivery of BCTs. Programme-level changes such as structured activities supported by participant materials and with sufficient allocated time, might improve the delivery of BCTs targeting self-regulation.

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.

South Asian individuals' experiences on the NHS low-calorie diet programme: a qualitative study in community settings in England.

BACKGROUND: Existing literature examines barriers to the provision of ethnically diverse dietary advice, however, is not specific to total diet replacement (TDR). There is a lack of literature from the UK, limiting the potential applicability of existing findings and themes to the UK context. This study addresses this gap in research by interviewing participants of South Asian ethnicity who have undertaken the National Health Service (NHS) low-calorie diet programme (LCD) for people with type 2 diabetes living with overweight or obesity. This study explores factors that may affect the uptake and acceptability of its TDR, food reintroduction and weight maintenance stages. This aims to provide rich data that can inform effective tailoring of future programmes with South Asian participants. OBJECTIVE: To explore the perspectives of individuals of South Asian ethnicity on an NHS programme using TDR approaches for the management of type 2 diabetes (T2D). DESIGN: Qualitative study. SETTING: Individuals in the community undertaking the NHS LCD programme. PARTICIPANTS: Twelve one-to-one interviews were conducted with individuals from a South Asian ethnicity participating in the NHS LCD. MAIN OUTCOME MEASURES: Qualitative semistructured interviews conducted through different stages of the programme. Reflexive thematic analysis was used to analyse the transcripts. RESULTS: Key themes highlighted positive and negative experiences of the programme: (1) more work is needed in the programme for person centeredness; (2) it is not the same taste; (3) needing motivation to make changes and feel better; (4) a mixed relationship with the coach; (5) social experiences; (6) culture-related experiences. CONCLUSION: This study provides important experience-based evidence of the need for culturally tailored T2D programmes. Action to address these findings and improve the tailoring of the NHS LCD may improve experience, retention and outcomes on the programme for people of South Asian ethnicity and thereby reduce inequalities.

'Health Connections': study protocol for the development of a coproduced, community-based diet, physical activity, and healthy weight intervention for UK black and Asian adults.

INTRODUCTION: A limited number of diet, physical activity and weight management programmes suitable for UK black and Asian populations have been evaluated. We aim to coproduce 'Health Connections'-an ambitious new intervention to support dietary and physical activity choices, and maintaining a healthier weight, tailored to the needs of black Caribbean, black African and South Asian adults. Our existing research and public engagement work suggests that the intervention should be designed to be embedded in communities and delivered by peer educators supported by health professionals. METHODS AND ANALYSIS: The project is underpinned by a systems perspective that posits collective efficacy within communities, behaviour change theory and coproduction. Project activities will be conducted in three stages. Stage 1: semistructured interviews will be conducted with adults from diverse South Asian ethnic groups to understand their experiences, perspectives and intervention needs, adding to our existing data from black ethnic groups. We will synthesise the data, literature, available intervention resources and local practice, and develop the theoretical framework to codevelop intervention goals, programme theory and a draft logic model of change. Stage 2: a theorised list of potential intervention components, session content and mode/s of delivery will be explored in a modified Delphi exercise and workshop to achieve consensus on the intervention format. We will also develop prototype materials and a formal implementation plan. Stage 3: a description of the intervention will be documented. ETHICS AND DISSEMINATION: The study has received ethical approval from the School of Health Research Ethics Committee, Leeds Beckett University. Information on the project aims and voluntary participation is provided in the study participation information sheet. Consent will be certified by the completion and signing of a consent form prior to data collection. Dissemination for a range of stakeholders and audiences will include publications, presentations, short films and an infographic.

A Randomised Control Trial Investigating the Efficacy of the MapMe Intervention on Parental Ability to Correctly Categorise Overweight in Their Child and the Impact on Child BMI Z-Score Change at 1 Year.

Research suggests parental ability to recognise when their child has overweight is limited. It is hypothesised that recognition of child overweight/obesity is fundamental to its prevention, acting as a potential barrier to parental action to improve their child's health-related behaviours and/or help seeking. The purpose of this study was to investigate the efficacy of an intervention (MapMe) to improve parental ability to correctly categorise their child as having overweight one-month post-intervention, and reduce child body mass index (BMI) z-score 12 months post-intervention. MapMe consists of body image scales of known child BMI and information on the consequences of childhood overweight, associated health-related behaviours and sources of support. We conducted a three-arm (paper-based MapMe, web-based MapMe and control) randomised control trial in fifteen English local authority areas with parents/guardians of 4-5- and 10-11-year-old children. Parental categorisation of child weight status was assessed using the question 'How would you describe your child's weight at the moment?' Response options were: underweight, healthy weight, overweight, and very overweight. Child weight status and BMI z-scores were calculated using objectively measured height and weight data and UK90 clinical thresholds. There was no difference in the percentage of parents correctly categorising their child as having overweight/very overweight (n = 264: 41% control, 48% web-based, and 43% paper-based, p = 0.646). BMI z-scores were significantly reduced for the intervention group at 12 months post-intervention compared to controls (n = 338, mean difference in BMI z-score change -0.11 (95% CI -0.202 to -0.020, p = 0.017). MapMe was associated with a decrease in BMI z-score 12 months post-intervention, although there was no direct evidence of improved parental ability to correctly categorise child overweight status. Further work is needed to replicate these findings in a larger sample of children, investigate mechanisms of action, and determine the use of MapMe as a public health initiative.

Perceptions of dietary intake amongst Black, Asian and other minority ethnic groups in high-income countries: a systematic review of qualitative literature.

BACKGROUND: Minority ethnic groups are a fast-growing population in many high-income countries, partly due to the increasing population of immigrants and second-generation migrants. The dietary practices of some of these minority ethnic groups might make them to be disproportionately affected by obesity and increase their risks of developing non-communicable diseases. Population-specific interventions and strategies are vital to addressing poor nutritional practices among this population. Thus, this study systematically reviewed the perceptions of dietary intake amongst Black, Asian and other minority ethnic groups in high-income countries. METHODS: This systematic review was conducted in line with the guidelines of the Joanna Briggs Institute (JBI) methodology for systematic reviews, using a meta-aggregative design. This systematic review identified and synthesised qualitative literature on the perceptions of dietary intake amongst BlackAsian and other minority  ethnic groups in high-income countries. An extensive and comprehensive database search was conducted between January 2000 - May 2022 and included twenty (20) studies that met the eligibility criteria from six countries. The included studies were assessed for quality using the JBI qualitative assessment and review instrument. The JBI data extraction tools were used to retrieve relevant data from included articles, and the data were thematically analysed. RESULTS: We identified eight major themes across this database: (1) "Social and Cultural Factors," (2) "Availability and Accessibility," (3) "Family and Community Influences," (4) "Food Preferences", (5) "Home Country Food Versus Host Country Food" (6) "Dietary Acculturation" (7) "Health and Healthy Eating" (8) "Perception of Nutritional Information." CONCLUSION: Overall, Black, Asian, and other minority ethnic groups individuals were found to be aware of the effects of unhealthy eating on their health, and some of them have nutritional knowledge, but social and cultural factors, including structural factors, were deterrents to their healthy eating behaviours. An important finding from this review is that some participants believed that nutritional information, based on bio-medical science, was intended for only White population groups and that it was antagonistic to their cultural and community well-being.

"I am not really into the government telling me what I need to eat": exploring dietary beliefs, knowledge, and practices among ethnically diverse communities in England.

BACKGROUND: Communities with diverse ethnicity in high-income countries are disproportionately affected by poor diet-related health outcomes. In England, the United Kingdom's government's healthy eating dietary resources are not well accepted and are underutilised among this population. Thus, this study explored perceptions, beliefs, knowledge, and practices around dietary intake among communities with African and South Asian ethnicity residing in Medway, England. METHODS: This qualitative study generated data from 18 adults aged 18 and above using a semi-structured interview guide. These participants were sampled using purposive and convenience sampling strategies. All the interviews were conducted in English over the telephone, and responses were thematically analysed. RESULTS: Six overarching themes were generated from the interview transcripts: eating patterns, social and cultural factors, food preferences and routines, accessibility and availability, health and healthy eating, and perceptions about the United Kingdom government's healthy eating resources. CONCLUSION: The results of this study indicate that strategies to improve access to healthy foods are required to improve healthy dietary practices among the study population. Such strategies could help address this group's structural and individual barriers to healthy dietary practices. In addition, developing a culturally responsive eating guide could also enhance the acceptability and utilisation of such resources among communities with ethnic diversity in England.

How is online self-reported weight compared with image-captured weight? A comparative study using data from an online longitudinal study of young adults.

BACKGROUND: Accurate anthropometric measurement is important within epidemiological studies and clinical practice. Traditionally, self-reported weight is validated against in-person weight measurement. OBJECTIVES: This study aimed to 1) determine the comparison of online self-reported weight against images of weight captured on scales in a young adult sample, 2) compare this across body mass index (BMI), gender, country, and age groups, and 3) explore demographics of those who did/did not provide a weight image. METHODS: Cross-sectional analysis of baseline data from a 12-mo longitudinal study of young adults in Australia and the UK was conducted. Data were collected by online survey via Prolific research recruitment platform. Self-reported weight and sociodemographics (for example, age, gender) were collected for the whole sample (n = 512), and images of weight for a subset (n = 311). Tests included Wilcoxon signed-rank test to evaluate differences between measures, Pearson correlation to explore the strength of the linear relationship, and Bland-Altman plots to evaluate agreement. RESULTS: Self-reported weight [median (interquartile range), 92.5 kg (76.7-112.0)] and image-captured weight [93.8 kg (78.8-112.8)] were significantly different (z = -6.76, P < 0.001), but strongly correlated (r = 0.983, P < 0.001). In the Bland-Altman plot [mean difference -0.99 kg (-10.83, 8.84)], most values were within limits of agreement (2 standard deviation). Correlations remained high across BMI, gender, country, and age groups (r > 0.870, P < 0.002). Participants with BMI in ranges 30-34.9 and 35-39.9 kg/m2 were less likely to provide an image. CONCLUSIONS: This study demonstrates the method concordance of image-based collection methods with self-reported weight in online research.
