A cluster-randomised feasibility trial of a children\u2019s weight management programme: the Child weigHt mANaGement for Ethnically diverse communities (CHANGE) study

BackgroundCommunity-based programmes for children with excess weight are widely available, but few have been developed to meet the needs of culturally diverse populations. We adapted an existing children’s weight management programme, focusing on Pakistani and Bangladeshi communities. We report the evaluation of this programme to assess feasibility of programme delivery, acceptability of the programme to participants from diverse communities, and feasibility of methods to inform a future trial.MethodsA cluster-randomised feasibility trial was undertaken in a large UK city. Children’s weight management programmes (n = 24) were randomised to be delivered as the adapted or the standard programme (2:1 ratio). Routine data on participant attendance (n = 243) at the sessions were used to estimate the proportion of families completing the adapted and standard programmes (to indicate programme acceptability). Families planning to attend the programmes were recruited to participate in the feasibility study (n = 92). Outcome data were collected from children and parents at baseline, end of programme, and 6 months post-programme. A subsample (n = 24) of those attending the adapted programme participated in interviews to gain their views of the content and delivery and assess programme acceptability. Feasibility of programme delivery was assessed through observation and consultation with facilitators, and data on costs were collected.ResultsThe proportion of Pakistani and Bangladeshi families and families of all ethnicities completing the adapted programme was similar: 78.8% (95% CI 64.8–88.2%) and 76.3% (95% CI 67.0–83.6%) respectively. OR for completion of adapted vs. standard programme was 2.40 (95% CI 1.32–4.34, p = 0.004). The programme was feasible to deliver with some refinements, and participant interview data showed that the programme was well received. Study participant recruitment was successful, but attrition was high (35% at 6 months). Data collection was mostly feasible, but participant burden was high. Data collection on cost of programme delivery was feasible, but costs to families were more challenging to capture.ConclusionsThis culturally adapted programme was feasible to deliver and highly acceptable to participants, with increased completion rates compared with the standard programme. Consideration should be given to a future trial to evaluate its clinical and cost-effectiveness.Trial registrationISRCTN81798055, registered: 13/05/2014

Weight-management in children living with asthma: a qualitative study of the experiences of paediatric healthcare professionals

Objective: Weight loss has been found to improve the symptoms of asthma in children who are overweight. However, many paediatric weight management programmes do not address the challenges associated with living with asthma. The aim of this study was to explore the views and experiences of paediatric healthcare professionals concerning weight management advice and support offered to families of children living with asthma. Methods: In-depth individual interviews with 10 healthcare professionals who work with a paediatric asthma population (n = 4 Respiratory Consultants, 3 Respiratory Nurses, 3 General Paediatricians). Data were analysed using a Framework approach. Results: Healthcare professionals highlighted that families’ perceptions of weight, their approach to physical activity and nutrition, the family’s social context and perceptions of asthma and asthma treatment all influence weight management in children living with asthma. Initiating weight management conversations and referring to weight management support were perceived as challenging. It was thought that tailoring weight management to the needs of children living with asthma and locating support within the community were important to the success of a family-centred intervention. Conclusions: The results highlight the added complexity of responding to excessive weight in a paediatric population with asthma. Training and referral guidance for healthcare professionals may help overcome weight management support challenges. Addressing family beliefs about the factors influencing paediatric asthma and exploring families’ motivations for behaviour change may enhance engagement with weight management.

Use of Metformin for Weight Management in Children and Adolescents With Obesity in the Clinical Setting

Use of metformin for weight loss for children in a clinical setting has not been well described; therefore, we aimed to identify characteristics of obese patients prescribed metformin in a clinical setting and evaluate changes in anthropometric measures. Records of obese patients aged 10 to 18 years without diabetes attending an academic endocrinology practice from 2009 to 2013 were reviewed. Analyses assessed changes in anthropometric measures (weight, body mass index [BMI], and BMI z-score) over 12 months between those prescribed metformin (n = 49) and those not prescribed metformin (n = 142). Outcomes were standardized before using multivariable linear regression models. Patients prescribed metformin were significantly older, more often female, and had larger baseline anthropometric measures (all P < .05). In the models, subjects prescribed metformin had significantly less gain in standardized weight, BMI, and BMI z-score over 6 and 12 months (all P < .05). Metformin may be a useful weight management aid in children in a clinical setting.

Impact of a 6-month family-based weight management programme on child food and activity behaviours: short-term and long-term outcomes of the PEACH™ intervention.

The PEACH™ randomized controlled trial measured changes to children's food and activity behaviours following participation in a weight management programme. We have previously reported a 10% reduction in body mass index z-score at intervention end (6-month post-baseline) that was maintained to 24months with no further intervention for the full study sample. The objective of the study is to report changes in food and activity outcomes in the full sample at (i) the end of the 6-month intervention and (ii) 24-month post-baseline (18-month post-intervention). Changes in dietary and activity outcomes were assessed over time (baseline: n=169, 8.1±1.2years, body mass index z-score 2.72±0.62). Dietary intake was assessed using the Child Dietary Questionnaire, and times spent active and sedentary were assessed using a study-specific questionnaire. Linear mixed models were used. There were significant time effects for all Child Dietary Questionnaire scores and activity and sedentary behaviours in the expected direction. Significant sex effects were observed for fruit and vegetable and sweetened beverages scores and for time spent in small screen-based activity. This is one of few child weight management studies to report short-term and long-term behaviour outcomes. It demonstrates that an intervention promoting food and activity behaviours consistent with guidelines can achieve modest changes, mediating improvements in relative weight.

A description of health care system factors in the implementation of universal weight management services for children with overweight or obesity: case studies from Queensland and New South Wales, Australia

BackgroundThe prevalence of childhood obesity poses an urgent global challenge. The World Health Organization (WHO) Commission on Ending Childhood Obesity recommends the provision of appropriate family-based, lifestyle weight management services through universal health care to support families of children with overweight or obesity; however, there are few examples of their implementation ‘at scale’. The purpose of this research was to compare and contrast the impact of system and organisational factors on the implementation of childhood obesity management services within two Australian States (New South Wales and Queensland) to comprehensively describe their influence on the achievement of the WHO recommendation.MethodsPurposeful stratified sampling was used to select health service study sites (n = 16) representative of program implementation (none, discontinued, repeated) and geographic location within each State. Within each health service site, staff involved in program delivery, co-ordination and management roles participated (n = 39). An additional 11 staff involved in implementation at State level also participated. The Consolidated Framework for Implementation Research (CFIR) was used to develop interview scripts. Telephone interviews were recorded and transcribed. Transcripts were thematically coded and scored according to CFIR constructs and rating rules to identify enablers and barriers to implementation according to sample characteristics.ResultsNew South Wales achieved ongoing implementation; Queensland did not. Enablers included a quality evidence-based program, State government recognition of the urgency of the health issue and a commitment to address it, formally appointed and funded internal implementation leaders, strong communication and reporting at all levels. Barriers included the complexity of the health issue, in particular a lack of clear roles and responsibilities for local health service delivery, inadequate ongoing funding and challenges in meeting the diverse needs of families.ConclusionsThis research is an important progression of the evidence base in relation to the translation of childhood obesity management trials into routine health service delivery. Understanding enablers and barriers to program implementation ‘at scale’ is imperative to inform future planning and investment by Australia and WHO member states to meet their commitment to deliver childhood weight management services as part of universal health coverage.

Addressing childhood obesity in low-income, ethnically diverse families: outcomes and peer effects of MEND 7-13 when delivered at scale in US communities.

Implementation of a large-scale, child weight management program in low-income, ethnically diverse communities provided an important opportunity to evaluate its effectiveness under service level conditions (i.e. provision as a primary care child weight management service). MEND 7-13 is a community-based, multi-component, childhood obesity intervention designed to improve dietary, physical activity and sedentary behaviors. It comprises twice weekly sessions for 10 consecutive weeks (35 contact hours) and is delivered to groups of children and accompanying parents/caregivers. The evaluation used an uncontrolled, repeated measures design. Overall, 3782 children with overweight or obesity attended 415 MEND 7-13 programs in eight US states, of whom 2482 children (65.6%) had complete data for change in zBMI. The intervention targeted low-income, ethnically diverse families. Changes in anthropometric, cardiovascular fitness and psychological outcomes were evaluated. A longitudinal multivariate imputation model was used to impute missing data. Peer effects analysis was conducted using the instrumental variables approach and group fixed effects. Mean changes in BMI and zBMI at 10 weeks were -0.49 kg/m2 (95% CI: -0.67, -0.31) and -0.06 (95% CI: -0.08, -0.05), respectively. Benefits were observed for cardiovascular fitness and psychological outcomes. Mean peer reduction in zBMI was associated with a reduction in participant zBMI in the instrumental variables model (B = 0.78, P = 0.04, 95% CI: 0.03, 1.53). Mean program attendance and retention were 73.9% and 88.5%, respectively. Implementing MEND 7-13 under service level conditions was associated with short-term improvements in anthropometric, fitness and psychological indices in a large sample of low-income, ethnically diverse children with overweight and obesity. A peer effect was quantified showing that benefits for an individual child were enhanced, if peers in the same group also performed well. To our knowledge, this is the first US study to evaluate outcomes of an up-scaled community-based, child weight management program and to show positive peer effects associated with participation in the intervention.

Barriers and facilitators to health care professionals discussing child weight with parents: A meta-synthesis of qualitative studies.

IntroductionChildhood obesity is one of the most serious global public health challenges. However, obesity and its consequences are largely preventable. As parents play an important role in their children's weight‐related behaviours, good communication between parents and health care professionals (HCPs) is essential. This systematic review provides a meta‐synthesis of qualitative studies exploring the barriers and facilitators experienced by HCPs when discussing child weight with parents.MethodsSearches were conducted using the following databases: MEDLINE (OVID), Psych INFO (OVID), EMBASE (OVID), Web of Knowledge and CINAHL. Thirteen full‐text qualitative studies published in English language journals since 1985 were included. Included studies collected data from HCPs (e.g., nurses, doctors, dieticians, psychologists, and clinical managers) concerning their experiences of discussing child weight‐related issues with parents. An inductive thematic analysis was employed to synthesize findings.FindingsEmerging subthemes were categorized using a socio‐ecological framework into intra/interpersonal factors, organizational factors, and societal factors. Perceived barriers and facilitators most commonly related to intra/interpersonal level factors, that is, relating to staff factors, parental factors, or professional–parent interactions. HCPs also attributed a number of barriers, but not facilitators, at the organizational and societal levels.ConclusionThe findings of this review may help to inform the development of future weight‐related communication interventions. Whilst intra/interpersonal interventions may go some way to improving health care practice, it is crucial that all stakeholders consider the wider organizational and societal context in which these interactions take place. Statement of contribution What is already known on the subject? Childhood obesity is one of the United Kingdom's most serious current public health challenges.Health care professionals are in a prime position to identify child weight issues during routine consultations.However, they often feel unable or unequipped to raise the topic and provide information on child weight management. What does this study add? To our knowledge, this is the first review to synthesize barriers and facilitators to discussing child weight.This review interprets key barriers and facilitators in the context of the socio‐ecological model.Supports the development of interventions matched to the appropriate level of the socio‐economic model.

Exploring parent attitudes around using incentives to promote engagement in family-based weight management programs.

Incentives can promote adult wellness. We sought to examine whether incentives might help overcome barriers to engagement in child weight management programs and the ideal value, type and recipient of incentives. In 2017, we conducted semi-structured phone interviews with parents of children ≤17 years old, formerly or currently affected by obesity, who had (n = 11) or had never (n = 12) participated in family-based behavioral treatment (FBT) for obesity. Interviews explored the range and type of incentives families would be willing to accept. Interview transcripts were coded and data were analyzed using a thematic analysis. We found that some parents were skeptical about receiving cash incentives. However, once treatment-related costs were identified, some became more interested in reimbursement for out of pocket expenditures. Most parents felt up to $100/month would be adequate and that incentives should be tied to changing behaviors, not BMI. Some interviewees expressed preferences for non-cash incentives (e.g. a gift card) over cash incentives. Parents were willing to share incentives with adolescents, up to $50/month, but there was concern about incentives affecting a child's intrinsic motivation for behavior change. All parents acknowledged that moderate incentives alone couldn't overcome the realities of structural and familial barriers to engaging in weight management programs. In summary, we identified aspects of an incentive program to promote engagement in FBT that would be desirable and feasible to implement. Future quantitative work can reveal the value and structure of incentives that are effective for improving obesogenic health behaviors and outcomes.

Strategies to Recruit a Diverse Low-Income Population to Child Weight Management Programs From Primary Care Practices.

Purpose and ObjectivesPrimary care practices can be used to engage children and families in weight management programs. The Texas Childhood Obesity Research Demonstration (TX CORD) study targeted patients at 12 primary care practices in diverse and low-income areas of Houston, Texas, and Austin, Texas for recruitment to a trial of weight management programs. This article describes recruitment strategies developed to benefit both families and health care practices and the modification of electronic health records (EHRs) to reflect recruitment outcomes.Intervention ApproachTo facilitate family participation, materials and programs were provided in English and Spanish, and programs were conducted in convenient locations. To support health care practices, EHRs and print materials were provided to facilitate obesity recognition, screening, and study referral. We provided brief training for providers and their office staffs that covered screening patients for obesity, empathetic communication, obesity billing coding, and use of counseling materials.Evaluation MethodsWe collected EHR data from 2012 through 2014, including demographics, weight, and height, for all patients aged 2 to 12 years who were seen in the 12 provider practices during the study’s recruitment phase. The data of patients with a body mass index (BMI) at or above the 85th percentile were compared with the same data for patients who were referred to the study and patients who enrolled in the study. We also examined reasons that patients referred to the study declined to participate.ResultsOverall, 26% of 7,845 patients with a BMI at or above the 85th percentile were referred to the study, and 27% of referred patients enrolled. Enrollment among patients with a BMI at or above the 85th percentile was associated with being Hispanic and with more severe obesity than with patients of other races/ethnicities or less severe obesity, respectively. Among families of children aged 2 to 5 years who were referred, 20% enrolled, compared with 30% of families of older children (>5 y to 12 y). Referral rates varied widely among the 12 primary care practices, and referral rates were not associated with EHR modifications.Implications for Public HealthEngagement and recruitment strategies for enrolling families in primary care practice in weight management programs should be strengthened. Further study of factors associated with referral and enrollment, better systems for EHR tools, and data on provider and office adherence to study protocols should be examined. EHRs can track referral and enrollment to capture outcomes of recruitment efforts.

BackgroundStudies have suggested that obesity is linked within families and that successful interventions involve both the parent and child with obesity. However little information exists regarding similarities in adiposity and weight loss between the parent and child, especially in low socio-economic ethnically diverse households.MethodsThe purpose of this study was to examine the relationships between the changes from baseline over time in adiposity, weight, health behaviors, and self-efficacy in children (n = 184) and parents (n = 184) participating in an 18-month weight loss program. Within the intervention group only and for each post-baseline time point, Pearson correlation coefficients were computed for children’s changes (from baseline) in adiposity, weight, health behaviors, and self-efficacy, with their parents’ corresponding changes from baseline, to determine how strongly the dyads were correlated.ResultsAt the completion of 18 months, the intervention group parents demonstrated strong positive correlations between parent and child change in waist circumference (r = 0.409, p < 0.001), triceps (r = 0.332, p < 0.001), and subscapular (r = 0.292, p = 0.002) skinfolds. There were no significant correlations between weight, health behaviors, eating, and exercise self-efficacy.ConclusionsThe results suggest that in the Southern United States low-income parents and their children with obesity are strongly correlated.Trial registrationNCT01378806 Retrospectively Registered on June 22, 2011.

Development of a Measure to Assess Parent Perceptions of Barriers to Child Weight Management.

Families face many barriers related to creating or maintaining a healthy lifestyle, which likely contributes to the prevalence of childhood obesity in the United States; however, no measure currently exists to examine these barriers. This study developed a quantitative measure of parents' perceptions of barriers to family healthy lifestyle. Parents of children between the ages of 7-17 were recruited using Amazon Mturk (n = 812). Exploratory and confirmatory factor analyses and preliminary convergent validity analyses were conducted. Four factors emerged in the final measure: Parent Disengagement, Cost and Built Environment, Lack of Family Support, and Family Time Constraints, with the final 19-item measure having good initial psychometric properties, including reliability and validity. Future research is needed to examine whether this measure may be used in clinical practice to identify barriers to a healthy family lifestyle, to tailor interventions for families.

The adaptation and translation of the PEACH™ RCT intervention: the process and outcomes of the PEACH™ in the community trial

ObjectiveTo describe the process and report selected outcomes of translating an effective child weight management initiative (PEACH™) from a randomised controlled trial intervention to a community health programme. Study design and methodsPre-post study design utilising the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) evaluation framework. Adaptation of PEACH™ required significant promotional activity and consideration of legal, ethical and financial issues. PEACH™ components were revised and an evaluation design based on the RE-AIM framework was developed. Facilitator training workshops were made available to South Australian health or education professionals initially, then opened up to new graduates, interstate dietitians and others interested in professional development. Facilitators completed pretraining and post-training questionnaires and a third questionnaire following programme delivery. Data were collected from families by facilitators and returned to university staff for assessment of change (baseline to programme end) in body mass index (BMI) and waist circumference (WC) z-scores. ResultsChanges to organisational and political environments prevented maximum programme reach and adoption. Nonetheless, data indicated that PEACH™ was effective at improving facilitators' confidence (P < 0.05) and children's (n = 37) BMI z-score (−0.17, 95% confidence interval [CI]: 0.03:0.30, P = 0.016), WC z-score (−0.14, 95% CI: −0.02:0.30, P = 0.09) and lifestyle behaviours. Collection of maintenance data was prevented due to time and financial constraints. ConclusionsTranslational research needs to develop ways to effectively and efficiently bridge the gap between behavioural research and practice to improve the adoption of evidence-based approaches to child weight management. Nutrition educators and researchers can drive these nutrition-focussed translational research efforts forward. Funding bodies and health service organisations are encouraged to provide financial and structural support for such activity.

Commissioning guidance for weight assessment and management in adults and children with severe complex obesity.

The challenge of managing the epidemic of patients with severe and complex obesity disease in secondary care is largely unmet. In England, the National Institute of Health and Care Excellence and the National Health Service England have published guidance on the provision of specialist (non-surgical) weight management services. We have undertaken a systematic review of 'what evidence exists for what should happen in/commissioning of: primary or secondary care weight assessment and management clinics in patients needing specialist care for severe and complex obesity?' using an accredited methodology to produce a model for organization of multidisciplinary team clinics that could be developed in every healthcare system, as an update to a previous review. Additions to the previous guidance were multidisciplinary team pathways for children/adolescent patients and their transition to adult care, anaesthetic assessment and recommendations for ongoing shared care with general practitioners, as a chronic disease management pathway.

Big hearts, small hands: a focus group study exploring parental food portion behaviours

BackgroundThe development of healthy food portion sizes among families is deemed critical to childhood weight management; yet little is known about the interacting factors influencing parents’ portion control behaviours. This study aimed to use two synergistic theoretical models of behaviour: the COM-B model (Capability, Opportunity, Motivation – Behaviour) and Theoretical Domains Framework (TDF) to identify a broad spectrum of theoretically derived influences on parents’ portion control behaviours including examination of affective and habitual influences often excluded from prevailing theories of behaviour change.MethodsSix focus groups exploring family weight management comprised of one with caseworkers (n = 4), four with parents of overweight children (n = 14) and one with parents of healthy weight children (n = 8). A thematic analysis was performed across the dataset where the TDF/COM-B were used as coding frameworks.ResultsTo achieve the target behaviour, the behavioural analysis revealed the need for eliciting change in all three COM-B domains and nine associated TDF domains. Findings suggest parents’ internal processes such as their emotional responses, habits and beliefs, along with social influences from partners and grandparents, and environmental influences relating to items such as household objects, interact to influence portion size behaviours within the home environment.ConclusionThis is the first study underpinned by COM-B/TDF frameworks applied to childhood weight management and provides new targets for intervention development and the opportunity for future research to explore the mediating and moderating effects of these variables on one another.

Why consistent completion criterion are required in childhood weight management programmes

ObjectivesCurrent research in the field of childhood weight management (WM) effectiveness is hampered by inconsistent terminology and criterion for WM programme completion, alongside other engagement-related concepts (e.g. adherence, dropout and attrition). Evidence reviews are not able to determine conclusive intervention effectiveness because of this issue. This study aims to quantify how various completion criterion impacts upon on: 1) the percentage of WM completers; 2) the standardised body mass index (BMI SDS) reduction; and 3) the predictors of WM completion. Study designA methodological, sensitivity analysis to examine how differential completion criterion affect programme outcomes and predictors. MethodsSecondary data of 2948 children were used. All children attended a MoreLife WM programme between 2009 and 2014. The completion criterion was incrementally adjusted by 10% (i.e. completer attends 10%, 20%, 30%... of sessions) for research aims 1–2, with the percentage of completers and change in BMI SDS calculated at each increment. For aim 3, the stability (strength, direction and significance) of the predictors were examined when using the completion criterion of four alternative studies against our previous study (completion ≥70% attendance). ResultsThe volume of programme completers decreased in a linear manner as the completion criterion became more stringent (i.e. 70–100% attendance). The change in BMI SDS conversely became incrementally greater. The strength, direction and significance of the predictors was highly dependent on the completion criterion; the odds ratio varied by 24.2% across a single predictor variable (delivery period). The degree of change is evidenced in the paper. ConclusionsInconsistent completion criterion greatly limits the synthesis of programme effectiveness and explains some of the inconsistency in the predictors of engagement. Standardised criterion for engagement-related terminology are called for.
