Participant engagement with a UK community-based preschool childhood obesity prevention programme: a focused ethnography study

"It Should Be a Priority": Lessons Learned by Head Start Leaders, Staff, and Parent Facilitators Delivering a Multi-Site Parent-Centered Child Obesity Prevention Intervention

Background: Head Start, a federally funded preschool for low-income families, offers a unique space for interventionists to equitably reach parents and children, and promote healthful behavior for chronic disease prevention. However, determinants of implementation in this context remain understudied, hindering opportunities for improvement. We aim to identify organization-level factors affecting implementation of an obesity prevention program, as relayed by implementation partners at Head Start. Methods: Communities for Healthy Living (CHL), designed and implemented with Greater Boston Head Start (n = 16 programs across n = 2 agencies), is a cluster-randomized obesity prevention trial offering enhanced nutrition support, media campaign, and a parenting program. The current study draws on two years (2017-19) of data collected from Head Start implementation partners. Pre-implementation, staff completed anonymous surveys: implementation readiness (n = 119), staff training evaluation (n = 166), and facilitator training evaluation (n = 22); response frequencies were tabulated. Mid-implementation, staff and leadership participated in focus groups (n = 3 groups with n = 16 participants) and interviews (n = 9); transcripts were analyzed using a deductive-inductive hybrid approach, grounded in the Consolidated Framework for Implementation Research. Results: Most staff strongly agreed or agreed they understood their role (98.8%), planned on recruiting parents (98.2%), and reported commitment to implementation (92.5%); however, fewer identified CHL as a priority (69.7%) and were confident in their ability to coordinate efforts (84.9%), handle challenges (77.3%), and receive support (83.2%). Thematic analysis yielded implementation facilitators, including mission alignment, partner engagement in design, allocation of intervention-specific resources, and expressed leadership support. Barriers included strains imposed on staff workflow, a lack of shared responsibility, and challenges in coordinating CHL activities amidst competing Head Start programs. Conclusions: Responsive efforts to address deliverer-identified barriers to implementation may include reducing intervention impact on preexisting workflow, as well as clearly distinguishing intervention activities from preexisting Head Start programs.

A cross-sectional study assessing barriers and facilitators to the sustainability of physical activity and nutrition interventions in early childhood education and care settings

BACKGROUND

Effective evidence-based physical activity and nutrition interventions to prevent overweight and obesity and support healthy child development need to be sustained within Early Childhood Education and Care (ECEC) services. Despite this, little is known about factors that influence sustainability of these programs in ECEC settings. Therefore, the aim of this study was to describe the factors related to sustainability of physical activity and nutrition interventions in ECEC settings and examine their association with ECEC service characteristics.

METHODS

A cross-sectional study was undertaken with a nationally representative sample of 473 Australian ECEC services. Factors related to the sustainability of ECEC-based physical activity and nutrition interventions were assessed using the validated Integrated Measure of PRogram Element SuStainability in Childcare Settings (IMPRESS-C), measuring Outer Contextual Factors, Inner Contextual Factors, Processes and Characteristics of the Intervention domains for interventions that supervisors reported as currently implementing. Participants responded using a 5-point Likert scale, with responses ranging from 1 (completely disagree) to 5 (completely agree). Domain scores were calculated for each service by averaging item responses. Linear regression models between ECEC service characteristics and the IMPRESS-C domains were undertaken.

RESULTS

Data from 473 Australian childcare services nationally found that the domains: Processes ( x ¯ =3.78, SD = 0.64), consisting of partnership/engagement and training/support/supervision; and Outer Contextual Factors ( x ¯ =3.93, SD = 0.63), including policy and legislation, and socio-political context had the lowest mean scores indicating they may likely be barriers to sustainability. Linear regression analyses revealed no statistically significant associations between examined factors and ECEC service characteristics. There was a statistically significant association between the number of years services delivered their interventions and the Characteristics of the Intervention domain (p = 0.035) suggesting that this domain may influence sustainability of programs.

CONCLUSIONS

This study suggests that factors related to the Processes and Outer Contextual Factors domains had the lowest scores and as such, strategies to support the sustainability of physical activity and nutrition interventions implemented in ECEC settings may need to consider how to best address these factors.

Exploring parental and professional perceptions of weight management services among under-fives in England: A qualitative study

Background

Childhood obesity is a significant public health challenge, particularly among children under five. In England, weight management programs aim to address this issue; however, engagement and uptake of these services remain low. Understanding the perceptions of parents and professionals involved in these programs is crucial to enhancing participation and improving health outcomes. This study explores these perceptions to identify barriers and facilitators to effective engagement with weight management services.

Method

This qualitative study used purposive sampling to recruit parents and professionals involved in weight management programs across England. Semi-structured interviews were conducted with 15 participants (8 parents and 7 professionals). Data were transcribed, coded, and thematically analyzed using Braun and Clarke's six-phase framework to identify key themes related to engagement, cultural influences, and program effectiveness.

Results

The study identified several key themes: parental engagement, the impact of virtual versus face-to-face sessions, motivations for participation, barriers to involvement, and the role of cultural beliefs. Parental involvement was critical for the success of weight management programs, but barriers such as time constraints, cultural beliefs, and socioeconomic factors hindered participation. Professionals highlighted the need for more training and resources to effectively address these challenges. Cultural sensitivities and systemic support were found to be crucial for improving engagement and outcomes.

Conclusions

The findings emphasize the need for culturally tailored, accessible, and sustainable weight management interventions. Enhanced professional training, increased community outreach, and policy-level support are essential to improve engagement and ensure long-term success in addressing childhood obesity.

Profiles of Cultural Adaptation and Parenting Approach for Childhood Obesity in Lifestyle Interventions for Families With Young Children: A Systematic Review

BACKGROUND AND OBJECTIVES

Various interventions aim to reduce obesity and promote healthy lifestyles among different cultural groups.

METHODS

We have conducted a systematic literature review, following PRISMA guidelines (registered at https://doi.org/10.17605/OSF.IO/HB9AX), to explore profiles of cultural adaptation and parenting approach of lifestyle interventions for families with young children (1-4 years).

RESULTS

Our search (in CINAHL, ERIC, PsycINFO, PubMed, Scopus, and SSCI) yielded 41 studies reporting 31 interventions. Drawing on Intervention Mapping, we applied a newly developed framework with various indicators of cultural adaptation and a parenting approach to analyze interventions. Our review shows clear differences in the level of cultural adaptation. A categorical principal component analysis revealed 6 different empirical profiles of cultural adaptation.

CONCLUSIONS

Based on our profiles, we discuss how cultural adaptation can be strengthened in the design of future early interventions aimed at promoting a healthy lifestyle.

Defining focused ethnography: Disciplinary boundary-work and the imagined divisions between 'focused' and 'traditional' ethnography in health research - A critical review

This article offers the first critical review of focused ethnography, an increasingly popular research method across health disciplines. Focused ethnographers, we argue, exemplify the practice of methodological boundary work, defining their method in contrast to the 'traditional' ethnographic approach of anthropology and sociology. To examine this boundary work, we collected two samples of health research articles published over the last decade and compared how focused ethnographers and medical anthropologists described, justified, and practised ethnography. We found that the core characteristics most often asserted to differentiate focused ethnography from conventional ethnography were: a more limited study timeframe and scope; a limited subpopulation sample; more concentrated research questions; the inclusion of insider researchers; and more orientation towards applied results. We show, however, that these are imagined binaries that fail to map onto actual differences of practice in the two samples and which obscure many similarities between them. By contrast, we identified four alternative differences between the two methods of ethnography. These centre on understandings of 'research time'; the very meaning of ethnography; the relationship of researchers to 'data'; and the presumed best method of social intervention. We therefore define focused ethnography as a versatile method of ethnography that attends to specific epistemological expectations within the health sciences regarding valid proof and empirical description, the boundaries of research, the nature of research relationships, and the duty to improve biomedicine. Ultimately, our study highlights that methodological boundary-work matters, because assumed differences and unexpressed misunderstandings can prevent productive dialogue and fruitful collaboration between disciplines to address pressing health problems.

Barriers and facilitators to implementation of nutrition-related actions in school settings in low- and middle-income countries (LMICs): a qualitative systematic review using the Consolidated Framework for Implementation Research (CFIR)

BACKGROUND

Low- and middle-income countries (LMICs) are particularly vulnerable to the double burden of malnutrition: co-existence of underweight, overweight, obesity, and/or diet-related non-communicable diseases. Nutrition-related double-duty actions in school settings have been identified as one of the ways to address this challenge. However, to be able to take full advantage of the potential impact, it is important to understand their implementation as well. The aim of this paper is to systematically review qualitative research on barriers and facilitators to the implementation of nutrition-related actions in the school settings in LMICs.

METHODS

The following databases were searched: EMBASE, ERIC, MEDLINE, Global Health and PsycInfo (all on Ovid), Scopus (Elsevier), the Web of Science Social Sciences Citation Index, and Global Index Medicus from the World Health Organization. Of the 4253 identified records, 4030 were excluded after the abstract and title screen, leaving 223 for the full-text screen. A final 36 papers were included in this review. The consolidated framework for implementation research (CFIR) was used in the analysis.

RESULTS

We identified barriers and facilitators to implementation linked to the following CFIR constructs/sub-constructs: design quality and packaging, cost (intervention characteristics); target group needs and resources, cosmopolitanism, external policy and incentives (outer setting); structural characteristics, readiness for implementation (inner setting); knowledge and beliefs (characteristics of individuals) and engaging, executing (process). All identified constructs apart from target group needs and resources, knowledge and beliefs, and engaging were predominantly barriers. Available resources were the most prevalent barriers across studies.

CONCLUSION

This review identified barriers and facilitators to the implementation of nutrition-related actions based on qualitative articles in the school setting in LMICs, using the CFIR. Schools face continuous challenges in regard to funding and the government sector may have a role to play not only by offering financial assistance, but also through policy-making that would support healthy eating practices on school grounds.

Facilitators and Barriers to Implementation and Sustainability of Nutrition and Physical Activity Interventions in Early Childcare Settings: a Systematic Review

A stronger understanding of the factors influencing implementation of interventions in community-based early childcare settings is needed. The purpose of this systematic review was to synthesize existing research on facilitators and barriers to implementation and sustainability of nutrition and physical activity interventions in early childcare settings targeting 2-5-year-old children, including considerations for equitable implementation. This review adhered to PRISMA 2020 guidelines. Peer-reviewed literature was searched in PubMed, EMBASE, CINAHL, ERIC, and PsycINFO databases up to September 2020. Primary research studies that examined facilitators and barriers (or related synonyms) to the implementation and sustainability of nutrition and physical activity interventions in early childcare settings were eligible for inclusion. The search yielded 8092 records that were screened by four analysts in Covidence software with a final review of 24 studies. Two independent reviewers conducted study selection, data extraction, and quality appraisal (Mixed Methods Appraisal Tool). A "best fit" framework was applied using the Consolidated Framework for Implementation Research (CFIR) constructs to code barriers and facilitators. The most salient constructs were (1) "Available Resources," which was composed of time, staffing, space, and staff trainings; (2) adaptability; and (3) compatibility, the latter two indicating that easily modifiable interventions facilitated a smoother "fit" and were more likely to be successful, given adequate site-level resources. Only nine (28%) reported the use of a theory, model, or framework to guide evaluation; six studies (24%) included factors related to sustainability; and nine studies (38%) conducted their interventions with low-income or minoritized groups. The findings point to the need for intervention evaluations examining nutrition and physical activity to more consistently consider (a) sustainability factors early on in design and adoption phases; (b) use of theory, model, or framework to guide evaluation; and (c) equity-related frameworks and considerations for how equitable implementation.

Perceived factors that influence adoption, implementation and sustainability of an evidence-based intervention promoting healthful eating and physical activity in childcare centers in an urban area in the United States serving children from low-income, racially/ethnically diverse families

Introduction

Early childcare centers offer optimal settings to provide healthy built environments where preschool age children spend a majority of their week. Many evidence-based interventions (EBIs) promoting healthful eating and physical activity for early childcare settings exist, but there is a limited understanding of how best to support adoption, implementation and sustainability in community settings. This study examined how early childcare teachers and administrators from Chicago-area childcare centers serving children from low-income, racially/ethnically diverse communities viewed an EBI called Hip to Health (H3), and the factors they perceived as relevant for EBI adoption, implementation, and sustainability.

Methods

A multiple methods study including key informant interviews and a brief survey was conducted. Key informant interviews with teachers and administrators from childcare centers located in Chicago, IL were completed between December 2020 and May 2021. An interview guide and coding guide based on the Consolidated Framework for Implementation Research (CFIR) was developed. Interview transcripts were team coded in MAXQDA Qualitative Data Analysis software. Thematic analysis was used to identify findings specific to adoption, implementation, and sustainability. Participants were also asked to respond to survey measures about the acceptability, feasibility, and appropriateness of H3.

Results

Overall, teachers (n = 20) and administrators (n = 16) agreed that H3 was acceptable, appropriate, and feasible. Low start-up costs, ease-of-use, adaptability, trialability, compatibility, and leadership engagement were important to EBI adoption. Timely and flexible training was critical to implementation. Participants noted sustainability was tied to low ongoing costs, access to ongoing support, and positive observable benefits for children and positive feedback from parents.

Conclusions

These findings suggest that EBIs suitable for adoption, implementation, and sustainment in childcare centers serving racially/ethnically diverse, low-income families should be adaptable, easy to use, and low-cost (initial and ongoing). There is also some evidence from these findings of the heterogeneity that exists among childcare centers serving low-income families in that smaller, less resourced centers are often less aware of EBIs, and the preparation needed to implement EBIs. Future research should examine how to better support EBI dissemination and implementation to these settings.

Implementation Degree Assessment Sheet for Health Program in Japan by Customizing CFIR: Development and Validation

Purpose

More than 70% of public health nurses in Japan belong to government agencies, and there is a need for further evidence-based capacity development for program implementation. The purpose of this research was to develop an Implementation Degree Assessment Sheet (IDAS) by customizing the Consolidated Framework for Implementation Research (CFIR) to health programs in Japan.

Methods

The draft IDAS (five domains, 31 constructs) created by customizing the CFIR was refined by the researchers and modified through pre-testing. The survey covered full-time public health nurses (PHNs) affiliated to all prefectures and the cities with health centers of Japan. The survey was conducted as an anonymous, self-administered questionnaire survey by mail.

Results

One hundred eighty-five of the 334 institutions (55.4%) agreed to participate in our survey. Of the 966 questionnaire forms distributed, 709 forms (73.4%) were collected, of which 702 responses (72.7%) were valid. No item required consideration of deletion based on the results of item analysis, and our confirmatory factor analysis on model fitness between the five IDAS domains and CFIR showed sufficient fit indices after modification. With regard to reliability, Cronbach’s coefficient alpha, a measure of internal consistency, stayed above 0.8 overall. Our verification of stability with the split-half (odd/even) method resulted in a Spearman–Brown reliability coefficient of 0.95. The correlation coefficient between the IDAS scores and the research utilization competency score, used as an external criterion, was 0.51 (p<0.001), supporting the coexistence validity of the criterion-related validity of the IDAS. The significant differences were observed between known-groups, supporting the known-group validity of the IDAS.

Conclusion

This study developed the IDAS and confirmed constant reliability and validity. Hereafter, it is necessary to promote the required capacity development based on the actual degree of implementation in order to use the IDAS for the competency development of public health nurses and related professions to deliver health programs.

Participants' Engagement With Telephone Support Interventions to Promote Healthy Feeding Practices and Obesity-Protective Behaviours for Infant Obesity Prevention

BACKGROUND

Participant engagement with program interventions is vital to support intended behaviour changes and outcomes. The aim of this research was to investigate participant engagement with the Communicating Healthy Beginnings Advice by Telephone (CHAT) program, an early childhood obesity prevention program that included interventions for promoting healthy infant feeding practices and obesity-protective behaviours via telephone, and whether engagement with the telephone support program varied by participants' sociodemographic characteristics.

METHODS

This study used de-identified CHAT program data of participants who received the interventions via telephone. Data analysed included 1) participant engagement in telephone support from late pregnancy to 12 months of child's age, 2) demographic characteristics collected at late pregnancy and 3) intervention providers' observations and notes (qualitative data) for 10 participants from each engagement group (low, medium, high) to explore issues discussed during telephone support.

RESULTS

Call completion rate by participants was above sixty percent for all six stages of the telephone support program with more than half of the participants (57%) demonstrating high level of engagement. We found that participants' country of birth, employment status and annual household income were predictors of engagement with the telephone support provided in the CHAT program. The odds of participants' engagement with the telephone support program were 1.68 times higher for Australian born (95% CI 1.07 - 2.62), 1.63 times higher for participants who were employed (95% CI 1.01 - 2.66) and 1.63 times higher for participants with annual household income ≥AUD$80,000 (95% CI 1.02 - 2.60).

CONCLUSIONS

Participant engagement with the program interventions was good. Participants' engagement with the telephone support program was significantly associated with certain socio-demographic characteristics. Australian born participants, and participants associated with higher household income and employment engaged significantly more with the telephone support provided in the CHAT program. Additionally, the program engaged more participants older than 30 years of age and those who spoke English at home. The program provided unintended personal benefits to some participants with high engagement level due to their various psychosocial needs such as domestic violence, mental health and sleep related issues. Although not an intended benefit of the intervention, psychosocial needs of participants were met which was a likely factor for mothers' engagement with the program. This is an important factor that needs to be considered while implementing future programs or scale up of this program.

A cluster RCT and process evaluation of an implementation optimisation intervention to promote parental engagement enrolment and attendance in a childhood obesity prevention programme: results of the Optimising Family Engagement in HENRY (OFTEN) trial

Background

Poor and variable implementation of childhood obesity prevention programmes reduces their population impact and sustainability. We drew upon ethnographic work to develop a multi-level, theory-based implementation optimisation intervention. This intervention aimed to promote parental enrolment and attendance at HENRY (Health Exercise Nutrition for the Really Young), a UK community obesity prevention programme, by changing behaviours of children’s centre and local authority stakeholders.

Methods

We evaluated the effectiveness of the implementation optimisation intervention on HENRY programme enrolment and attendance over a 12-month implementation period in a cluster randomised controlled trial. We randomised 20 local government authorities (with 126 children’s centres) to HENRY plus the implementation optimisation intervention or to HENRY alone. Primary outcomes were (1) the proportion of centres enrolling at least eight parents per programme and (2) the proportion of centres with a minimum of 75% of parents attending at least five of eight sessions per programme. Trial analyses adjusted for stratification factors (pre-randomisation implementation of HENRY, local authority size, deprivation) and allowed for cluster design. A parallel mixed-methods process evaluation used qualitative interviews and routine monitoring to explain trial results.

Results

Neither primary outcome differed significantly between groups; 17.8% of intervention centres and 18.0% of control centres achieved the parent enrolment target (adjusted difference − 1.2%; 95% CI − 19.5%, 17.1%); 17.1% of intervention centres and 13.9% of control centres achieved the attendance target (adjusted difference 1.2%; 95% CI − 15.7%, 18.1%). Unexpectedly, the trial coincided with substantial national service restructuring, including centre closures and reduced funds. Some commissioning and management teams stopped or reduced delivery of both HENRY and the implementation optimisation intervention due to competing demands. Thus, at follow-up, HENRY programmes were delivered to approximately half the number of parents compared to baseline (n = 433 vs. 881).

Conclusions

During a period in which services were reduced by external policies, this first definitive trial found no evidence of effectiveness for an implementation optimisation intervention promoting parent enrolment to and attendance at an obesity prevention programme.

Impact of cuts to local government spending on Sure Start children's centres on childhood obesity in England: a longitudinal ecological study

BACKGROUND

Childhood obesity is rising in disadvantaged areas in England. Sure Start children's centres provide community-based services for children <5 years and their parents, including many services that can support healthy weight, directly or indirectly. Since 2010, austerity-driven cuts to local authority (LA) budgets have led to substantially reduced public expenditure on Sure Start services. We assessed whether childhood obesity prevalence has increased more since 2010 in those areas in England that experienced greater cuts to spending on Sure Start.

METHODS

This longitudinal ecological study covers the period 2010/2011-2017/2018. Our exposure was LA expenditure on Sure Start, using Department for Education data. Our main outcome was LA obesity prevalence at age 4-5 years, using National Child Measurement Programme data. We used fixed-effects panel regression to quantify the association between change in spending and change in the prevalence of childhood obesity.

RESULTS

Spending on Sure Start children's centres decreased on average 53% over the study period, with deeper cuts in more deprived LAs. Each 10% spending cut was associated with a 0.34% relative increase in obesity prevalence the following year (95% CI 0.15% to 0.53%). We estimated there were an additional 4575 children with obesity (95% CI 1751 to 7399) and 9174 overweight or obese (95% CI 2689 to 15 660) compared with expected numbers had funding levels been maintained.

CONCLUSIONS

Cuts to spending on Sure Start children's centres were associated with increased childhood obesity. With deprived areas experiencing bigger spending cuts, reinvesting in these services may, alongside wider benefits for child development, contribute to reducing inequalities in childhood obesity.

Planned Evaluation of the Healthy Weight Clinic Pediatric Weight Management and Implementation: Massachusetts-CORD 3.0

Background: Despite evidence that offering multidisciplinary treatment for children with obesity is effective, access to evidence-based pediatric weight management interventions (PWMIs) is limited. The Healthy Weight Clinic PWMI is a multidisciplinary approach in primary care that improves BMI among children with a BMI ≥ 85th percentile. Objective: To describe the method by which we will evaluate the adoption, acceptability, and feasibility of integrating and implementing a multidisciplinary Healthy Weight Clinic (HWC) into primary care. Design/Methods: We used the Consolidated Framework for Implementation Research (CFIR) domains and constructs to inform our implementation strategies. We will use a Type III hybrid effectiveness-implementation design to test our implementation strategies and improvement in BMI. Sources of data collection will include qualitative interviews with patient caregivers, HWC staff and surveys with HWC staff, patient caregivers, and electronic health record data. Our outcomes are guided by the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework. Results: We identified all five CFIR domains as integral for successful implementation. Some strategies to address barriers within these domains include online self-paced training modules for the HWC staff, a virtual learning collaborative, and engagement of site leadership. Outcomes will be measured at the patient and pilot site levels, and they will include patients reached, patient health outcomes such as BMI and quality of life, level of adoption, acceptability, feasibility, and sustainability of the PWMI. Conclusion: Our use of implementation science frameworks in the planning of Healthy Weight Clinic PWMI could create a sustainable and effective program for dissemination.

Cluster randomised controlled feasibility study of HENRY: a community-based intervention aimed at reducing obesity rates in preschool children

BACKGROUND

Community-based obesity prevention interventions are often commissioned despite the limited evidence base. HENRY (Health, Exercise, Nutrition for the Really Young) is a programme delivered to parents of preschool children across the UK. Early evidence suggests that it may be effective, but a robust evaluation has not been conducted. We initiated a systematic evaluation of HENRY by studying the feasibility of conducting a multi-centre definitive trial to evaluate its effectiveness and cost-effectiveness to prevent obesity. Objectives were to assess the feasibility of recruiting local authorities, centres and parents; test processes and time required to train and certify intervention staff; explore HENRY commissioning processes; identify potential sources (and associated impact) of contamination; and consider the feasibility of trial procedures.

METHODS

We conducted a multi-centre, open labelled, two group, prospective, cluster randomised, controlled, feasibility study, with embedded process evaluation and pre-defined criteria for progression to definitive trial. We sought to recruit 120 parents from 12 children's centres, across two UK local authority (government) areas. Within each local authority, we planned to randomise three centres to HENRY and three to 'standard care' control. Our plan was to collect data in family homes at baseline and 12 months, including parent and child height and weight, and parent-reported questionnaires on self-efficacy, feeding, eating habits, quality of life and resource use. Contamination, implementation and study acceptability were explored using parent interviews.

RESULTS

We recruited two local authorities and 12 children's centres within eight months. One hundred and seventeen parents were recruited (average 3.9 parents per programme) and follow-up data were collected from 85% of participants. Process data from 20 parents and 24 members of staff indicate that both would benefit from more detail about their involvement as participants, but that methods were acceptable. Contamination was likely, though the impact of this on behaviour was unclear.

CONCLUSION

Our findings indicate that a cluster RCT of HENRY to assess its effect on childhood obesity prevention is feasible. This study has allowed us to design a pragmatic definitive trial with minimal bias, taking account of lessons learnt from conducting evaluation research in public health settings.

The Development of a Multilevel Intervention to Optimise Participant Engagement with an Obesity Prevention Programme Delivered in UK children's Centres

Poor participant engagement threatens the potential impact and cost-effectiveness of public health programmes preventing meaningful evaluation and wider application. Although barriers and levers to engagement with public health programmes are well documented, there is a lack of proven strategies in the literature addressing these. This paper details the development of a participant engagement intervention aimed at promoting enrolment and attendance to a community-based pre-school obesity prevention programme delivered in UK children’s centres; HENRY (Health, Exercise, Nutrition for the Really Young). The Behaviour Change Wheel framework was used to guide the development of the intervention. The findings of a coinciding focused ethnography study identified barriers and levers to engagement with HENRY that informed which behaviours should be targeted within the intervention to promote engagement. A COM-B behavioural analysis was undertaken to identify whether capability, opportunity or motivation would need to be influenced for the target behaviours to occur. APEASE criteria were used to agree on appropriate intervention functions and behaviour change techniques. A multi-level participant engagement intervention was developed to promote adoption of target behaviours that were proposed to promote engagement with HENRY, e.g. ensuring the programme is accurately portrayed when approaching individuals to attend and providing ‘taster’ sessions prior to each programme. At the local authority level, the intervention aimed to increase buy-in with HENRY to increase the level of resource dedicated to engagement efforts. At the centre level, managers were encouraged to widen promotion of the programme and ensure that staff promoted the programme accurately. HENRY facilitators received training to increase engagement during sessions, and parents that had attended HENRY were encouraged to recruit their peers. This paper describes one of the first attempts to develop a theory-based multi-level participant engagement intervention specifically designed to promote recruitment and retention to a community-based obesity prevention programme. Given the challenges to implementing public health programmes with sufficient reach, the process used to develop the intervention serves as an example of how programmes that are already widely commissioned could be optimised to enable greater impact.

The "Stages Towards Completion Model": what helps and hinders children with overweight or obesity and their parents to be guided towards, adhere to and complete a group lifestyle intervention

Purpose: Lifestyle interventions can be effective in the management of overweight and obesity in children. However, ineffective guidance towards interventions and high attrition rates affect health impacts and cost effectiveness. The aim of this study was to gain insight into the factors influencing participation, in particular guidance towards, adherence to and completion of an intervention.

Methods: A narrative literature review was performed to identify factors related to participation, leading to the development of the “Stages towards Completion Model”. Semi-structured interviews (n = 33) and three focus group discussions (n = 25) were performed with children and parents who completed two different group lifestyle interventions, as well as with their coaches.

Results: The main barrier to participating in a lifestyle intervention was the complex daily reality of the participants. The main facilitator to overcome these barriers was a personal approach by all professionals involved.

Conclusions: Participation in a lifestyle intervention is not influenced by one specific factor, but by the interplay of facilitators and barriers. A promising way to stimulate participation and thereby increase the effectiveness of interventions would be an understanding of and respect for the complex circumstances of participants and to personalize guidance towards and execution of interventions.

Measuring commissioners' willingness-to-pay for community based childhood obesity prevention programmes using a discrete choice experiment

BACKGROUND

In the UK, rates of childhood obesity remain high. Community based programmes for child obesity prevention are available to be commissioned by local authorities. However, there is a lack of evidence regarding how programmes are commissioned and which attributes of programmes are valued most by commissioners. The aim of this study was to determine the factors that decision-makers prioritise when commissioning programmes that target childhood obesity prevention.

METHODS

An online discrete choice experiment (DCE) was used to survey commissioners and decision makers in the UK to assess their willingness-to-pay for childhood obesity programmes.

RESULTS

A total of 64 commissioners and other decision makers completed the DCE. The impact of programmes on behavioural outcomes was prioritised, with participants willing to pay an extra £16,600/year if average daily fruit and vegetable intake increased for each child by one additional portion. Participants also prioritised programmes that had greater number of parents fully completing them, and were willing to pay an extra £4810/year for every additional parent completing a programme. The number of parents enrolling in a programme (holding the number completing fixed) and hours of staff time required did not significantly influence choices.

CONCLUSIONS

Emphasis on high programme completion rates and success increasing children's fruit and vegetable intake has potential to increase commissioning of community based obesity prevention programmes.
