Parents as agents of change (PAC) in pediatric weight management: the protocol for the PAC randomized clinical trial

Family systems approaches in pediatric obesity management: a scoping review

Family-based obesity management interventions targeting child, adolescent and parental lifestyle behaviour modifications have shown promising results. Further intervening on the family system may lead to greater improvements in obesity management outcomes due to the broader focus on family patterns and dynamics that shape behaviours and health. This review aimed to summarize the scope of pediatric obesity management interventions informed by family systems theory (FST). Medline, Embase, CINAHL and PsycInfo were searched for articles where FST was used to inform pediatric obesity management interventions published from January 1980 to October 2023. After removal of duplicates, 6053 records were screened to determine eligibility. Data were extracted from 50 articles which met inclusion criteria; these described 27 unique FST-informed interventions. Most interventions targeted adolescents (44%), were delivered in outpatient hospital settings (37%), and were delivered in person (81%) using group session modalities (44%). Professionals most often involved were dieticians and nutritionists (48%). We identified 11 FST-related concepts that guided intervention components, including parenting skills, family communication, and social/family support. Among included studies, 33 reported intervention effects on at least one outcome, including body mass index (BMI) (n = 24), lifestyle behaviours (physical activity, diet, and sedentary behaviours) (n = 18), mental health (n = 12), FST-related outcomes (n = 10), and other outcomes (e.g., adiposity, cardiometabolic health) (n = 18). BMI generally improved following interventions, however studies relied on a variety of comparison groups to evaluate intervention effects. This scoping review synthesises the characteristics and breadth of existing FST-informed pediatric obesity management interventions and provides considerations for future practice and research.

Using the RE-AIM framework to evaluate the feasibility of a parent-focused intervention targeting childhood obesity

BACKGROUND

Childhood obesity remains a serious public health concern. Community-based childhood obesity treatment interventions have the potential to improve health behaviors and outcomes among children, but require thorough evaluation to facilitate translation of research into practice. The purpose of the current study was to determine the feasibility of a community-based, parent-focused childhood obesity intervention ("C.H.A.M.P. Families") using the RE-AIM framework, an evaluation tool for health interventions.

METHODS

A single-group, non-randomized, repeated measures feasibility study was conducted. Participants (n = 16 parents/caregivers of 11 children with obesity) completed a 13-week parent-focused education intervention. The intervention consisted of three main components: (a) eight group-based (parent-only) education sessions; (b) eight home-based (family-centered) activities; and (c) two group-based follow-up support sessions for parents and children. The five dimensions of RE-AIM-reach, effectiveness, adoption, implementation, and maintenance-were assessed using various measures and data sources (e.g., child, parent/caregiver, costing, census) obtained throughout the study period. Outcome variables were measured at baseline, mid-intervention, post-intervention, and at a 6-month follow-up.

RESULTS

Overall, the C.H.A.M.P. Families intervention reached approximately 0.09% of eligible families in London, Ontario. Despite the small number, participants were generally representative of the population from which they were drawn, and program participation rates were high (reach). Findings also suggest that involvement in the program was associated with improved health-related quality of life among children (effectiveness/individual-level maintenance). In addition, the intervention had high fidelity to protocol, attendance rates, and cost-effectiveness (implementation). Lastly, important community partnerships were established and maintained (adoption/setting-level maintenance).

CONCLUSIONS

Based on a detailed and comprehensive RE-AIM evaluation, the C.H.A.M.P. Families intervention appears to be a promising parent-focused approach to the treatment of childhood obesity.

Parents as Agents of Change in Managing Pediatric Obesity: A Randomized Controlled Trial Comparing Cognitive Behavioral Therapy versus Psychoeducation Interventions

Background: Obesity interventions for parents of children with obesity can improve children's weight and health. This randomized controlled trial (RCT) evaluated whether a parent-based intervention based on cognitive behavioral therapy (CBT) principles was superior to a parent-based intervention based on a psychoeducation program (PEP) in improving children's obesity. Methods: This study was a pragmatic, two-armed, parallel, superiority RCT. Conducted at a Canadian outpatient pediatric obesity management clinic (September 2010-January 2014), this trial included families with children 8-12 years with an age- and sex-specific BMI ≥85th percentile. The 16-week manualized interventions were similar in content and delivered to parents exclusively, with different theoretical underpinnings. The primary outcome was children's BMI z-score at postintervention (4 months). Secondary outcomes included anthropometric, lifestyle, psychosocial, and cardiometabolic variables. Data were collected at preintervention (0 months), postintervention (4 months), 10, and 16 months. Intention-to-treat analysis using linear mixed models was used to assess outcomes. Results: Among 52 randomly assigned children, the mean age (standard deviation) was 9.8 (1.7) years and BMI z-score was 2.2 (0.3). Mean differences in BMI z-score were not significantly different between the CBT (n = 27) and PEP (n = 25) groups from 0 to 4-, 10-, and 16-month follow-up. At 4 months, the mean difference in BMI z-score from preintervention between the CBT (-0.05, 95% CI = -0.09 to 0.00) and PEP (-0.04, 95% CI = -0.09 to 0.01) groups was -0.01 (95% CI = -0.08 to 0.06, p = 0.80). Similar results were found across all secondary outcomes. Conclusions: Our CBT-based intervention for parents of children with obesity was not superior in reducing BMI z-score vs. our PEP-based intervention.

Parents' Experiences Using Digital Health Technologies in Paediatric Overweight and Obesity Support: An Integrative Review

This study aimed to explore parents' perspectives regarding the use of digital health technologies in paediatric overweight and obesity weight support. A systematic search in 'Academic Search Premier', 'British Nursing Index', 'Cumulative Index to Nursing and Allied Health', and 'Health Research Premium Collection' was conducted in November 2021. Inclusion criteria were English or Nordic peer-reviewed articles published after 2010, overweight and obese children aged 2-10, weight support using digital health technologies, and parental experiences examined. An integrative review was conducted using Joanna Briggs Institute quality appraisal checklists and a constant comparison analysis method. In total, 14 articles were analysed that included SMS, telephone, apps, websites, and social media as the main technology groups. A limitation of this review was the heterogenicity of the studies. The results indicate that parents, mostly mothers, had a positive experience, finding technologies helpful and easy to use, and expressed optimism toward future use. An option for interacting with others and the possibility of personalising support were enjoyed or requested. In conclusion, digital health technologies can be a suitable tool to empower the parents of children with overweight and obesity concerns, whose perspective should be considered during the design and support phases.

Step Count Associations Between Adults at Risk of Developing Diabetes and Their Children: The Feel4Diabetes Study

BACKGROUND

Shared risk factors of type 2 diabetes mellitus (T2DM) between parents at risk and their children, such as low physical activity levels, should be addressed to prevent the development of the disease. The aim of this study was to determine the association of objectively measured step counts per day between parents at risk of developing T2DM and their 6- to 10-year-old children.

METHODS

The baseline data from the Feel4Diabetes study were analyzed. Dyads of children and one parent (n = 250, 54.4% girls and 77.6% mothers) from Belgium were included. Step counts per day during 5 consecutive days from parents and their children were objectively measured with ActiGraph accelerometers.

RESULTS

Adjusted linear regression models indicated that parents' and children's step counts were significantly associated during all days (β = 0.245), weekdays (β = 0.205), and weekend days (β = 0.316) (P ≤ .002 in all cases). Specifically, mother-daughter associations during all days and weekend days and father-son step counts during weekdays and when considering all days were significant.

CONCLUSION

There is a positive association between step counts from adults at risk of developing T2DM and their children, especially in the mother-daughter and father-son dyads.

"It's not a simple answer." A qualitative study to explore how healthcare providers can best support families with a child with autism spectrum disorder and overweight or obesity

PURPOSE

This qualitative study aimed to explore the experiences of parents supporting their child with Autism Spectrum Disorder (ASD) and overweight or obesity (OW/OB), including their weight management support needs.

METHODS

Interview transcripts were analysed using inductive thematic analysis. Nine parents (n = 9 mothers) of ten children with ASD (7 males, 3 females) participated in individual semi-structured interviews.

RESULTS

The three themes developed were: (1) Our journey to obtain weight management support; (2) I need real-world solutions; and (3) The what, who and how of our weight management needs. Parents reported being proactive in seeking weight management support for their child but were disappointed with the services offered. Resources were not tailored to the child's complex nutrition and behavioural issues or their abilities and functioning. A multidisciplinary approach that integrated both disability and weight management expertise was desired, but not experienced. A range of formal and informal programs were recommended.

CONCLUSION

This study provides a call to action for supports that ensure children with ASD and OW/OB receive integrated, individualised support to maximise their health and wellness.Implications for rehabilitationChildren with autism spectrum disorder (ASD) are at high risk of developing overweight or obesity.The weight management support needs of parents of children with ASD and overweight or obesity are not being met.Support must be tailored to the child's needs, which are often complex.Health services that integrate expertise in both disability and weight management are needed for children with ASD and their families.

Promoting Healthy Eating and Regular Physical Activity in Low-Income Families Through Family-Centered Programs: Implications for Practice

Research concerning children who are overweight has historically focused on providing services to the affected individuals, and limited attention has been paid to their families. Further, childhood obesity prevention and clinical programs continue to be impacted by contextual factors that increase the likelihood of attrition when targeting underserved populations. This paper provides data with relevance for interventions aimed at promoting healthy eating and regular physical activity with low-income families. Participants in a childhood obesity exploratory study provided recommendations to improve programs by reflecting on specific family and contextual issues related to children who are overweight and obese. Following a thematic analysis approach, we conducted semi-structured interviews with 16 low-income, single, female parents. All participants had, at the time of the interview, at least one overweight or obese child between the ages of 3 and 8. We report the critical role of context in the etiology and challenges of childhood obesity among disadvantaged populations. Findings also highlight the need for interventions to be culturally relevant and sensitive and to create opportunities to address and discuss participant experiences of discrimination, cultural factors, and family of origin influences. Interventions that do not address these contextual factors run the risk of being unsuccessful. Our findings are important for mental and public health professionals who are interested in the direct provision of services using a combination of social determinants of systemic perspectives.

Weight Control Practices in Children of Parents Participating in Weight Management Programs

Background: Family members influence the behaviors and weight loss of adults in weight management programs (WMPs). Less is known about the weight control practices of children who have a parent participating in a WMP. Thus, we aimed to explore weight control practices in children of parents in WMPs. Methods: We recruited participants who were parents of least one child aged 2-18 living at home from two institution's adult WMPs. Parents reported weight control practices for themselves and their child. We used separate logistic regression models to assess the association of each child weight control practice with parent weight control practice; child age, race, sex, and BMI z-score (BMIz); parent education; and household income. Results: Parents (N = 300) had a mean age of 41 ± 7 and 85% were female. Children (N = 295) had a mean age of 9.3 ± 4.9; 20% had overweight or obesity. Parents reported their child used the following weight control practices in the past year: 12% dieted, 12% ate very little food, 7% used food substitutes, 10% skipped meals, 29% increased fruit and vegetables, 25% reduced calories, 22% reduced snacking, 21% reduced fat intake, and 45% exercised. Children were more likely to utilize weight control practices if their parent utilized the same weight control practice and if children had obesity and were older. Conclusions: Children of parents attending WMPs commonly utilize weight control practices, especially older children with higher BMIz. Adult WMPs should offer guidance to parents on ways to incorporate new healthy dietary practices into their family.

Participants' Perceptions of "C.H.A.M.P. Families": A Parent-Focused Intervention Targeting Paediatric Overweight and Obesity

Background: Recently, our team implemented a 13-week group-based intervention for parents of children with obesity ("C.H.A.M.P. Families"). The primary objective of this study was to explore, qualitatively, parents' perspectives of their experiences in and influence of C.H.A.M.P. Families, as well as their recommendations for future paediatric obesity treatment interventions. Methods: Twelve parents (seven mothers, five fathers/step-fathers) representing seven children (four girls, three boys) with obesity participated in one of two focus groups following the intervention. Focus groups were audio recorded and transcribed verbatim and data were analyzed using inductive thematic analysis. Results: Findings showed that parents perceived their participation in C.H.A.M.P. Families to be a positive experience. Participants highlighted several positive health-related outcomes for children, families, and parents. Parents also underscored the importance and positive impact of the group environment, specific educational content, and additional program components such as free child-minding. Recommendations for future interventions were also provided, including greater child involvement and more practical strategies. Finally, parents identified several barriers including socioenvironmental issues, time constraints, and parenting challenges. Conclusions: Researchers developing family-based childhood obesity interventions should consider the balance of parent and child involvement, as well as emphasize group dynamics strategies and positive family communication.

Development of the iCook 4-H Curriculum for Youth and Adults: Cooking, Eating, and Playing Together for Childhood Obesity Prevention

The objective was to describe the development process of a curriculum (iCook 4-H) targeted to low-income, rural, and/or diverse youths and their adult primary meal preparer to promote cooking, eating, and playing together. Lessons learned highlighted the importance of grounding the curriculum in Social Cognitive Theory and applying the experiential 4-H learning model using a multiphased, community-based participatory approach with cyclical development and evaluation, and key modifications made for dissemination and distribution. Findings across 4 testing phases over 6 years and 5 states demonstrated the time-intensive, cyclical process that required flexibility with fidelity to form a hands-on, interactive curriculum.

"C.H.A.M.P. Families": Description and Theoretical Foundations of a Paediatric Overweight and Obesity Intervention Targeting Parents-A Single-Centre Non-Randomised Feasibility Study

Childhood obesity represents a significant global health challenge, and treatment interventions are needed. The purpose of this paper is to describe the components and theoretical model that was used in the development and implementation of a unique parent-focussed paediatric overweight/obesity intervention. C.H.A.M.P. Families was a single-centre, prospective intervention offered to parents of children aged between 6–14 years with a body mass index (BMI) ≥85th percentile for age and sex. The intervention included: (1) eight group-based (parent-only) education sessions over 13-weeks; (2) eight home-based activities; and (3) two group-based (family) follow-up support sessions. The first section of the manuscript contains a detailed description of each intervention component, as well as an overview of ongoing feasibility analyses. The theoretical portion details the use of evidence-based group dynamics principles and motivational interviewing techniques within the context of a broader social cognitive theory foundation. This paper provides researchers with practical examples of how theoretical constructs and evidence-based strategies can be applied in the development and implementation of parent-focussed paediatric obesity interventions. Given the need for transparent reporting of intervention designs and theoretical foundations, this paper also adds to the areas of implementation science and knowledge translation research.

Assessing the feasibility of parent participation in a commercial weight loss program to improve child body mass index and weight-related health behaviors

Objectives:

Little is known about how children’s health might be affected by parents’ participation in commercial weight loss programs. Given that more than 3.2 million people subscribe to just one commercial weight loss program, Weight Watchers, any secondary effects on children’s weight-related health behaviors (e.g. dietary behaviors, physical activity, and sedentary time) and body mass index from parent participation in commercial weight loss programs may have significant public health implications. This study examined the feasibility of conducting a study to assess such effects. Methods for recruitment and retention, and perceived acceptability and satisfaction among participants in small-scale preliminary study, were evaluated. Changes in body mass index and health behaviors among the parent–child dyads were also measured to test whether a larger-scale study would be warranted.

Methods:

This was an 8-week, pre–post observational feasibility study involving 20 parent–child dyads where both members had overweight or obesity. Physical and behavioral data were collected at baseline and 8 weeks from both members of the dyads. Parenting data were collected at the same time periods through parents’ self-report. Bivariate correlation was used to quantify the associations in changes for dyad members.

Results:

Feasibility goals for retention and perceived acceptability/satisfaction among participants were met. We reached approximately 80% of our enrollment goal. Parents showed a significant decrease in body mass index of 0.53 points (p < 0.05), while children showed a significant increase in raw body mass index (0.42, p < 0.05) and body mass index percentile (0.59, p < 0.05). However, correlation between changes in parent body mass index and changes in children body mass index percentile was positively correlated (r = 0.24, p = 0.31). A decrease in parent intake of total fat was associated with a decrease in the intake of fat in their children (r = 0.47, p < 0.05).

Conclusion:

Our findings support the viability of a larger-scale follow-up to assess the potential of using parent-only commercial weight loss program as a mechanism for improving health behaviors and body mass index in children with overweight or obesity.

An Interactive Web-Based Intervention to Achieve Healthy Weight in Young Children

This prospective, randomized, controlled trial for parents of overweight and obese 3- to 7-year-olds was performed to assess the feasibility of a program promoting healthy eating and lifestyle by targeting parents as agents of change. The intervention was composed of 6-in-person group sessions and a customized website over 12 months. The control group received customary care. The primary outcome was feasibility of the intervention to promote healthy behavior change measured by attendance. The secondary outcome was effectiveness assessed by attaining reduced body mass index (BMI) z scores, healthy behavior changes and increased parent self-efficacy. Seventy-three child-parent dyads were enrolled; 14 parents never attended any sessions. Participation in follow-up assessments did not meet the hypothesized level. Ultimate BMI z scores did not differ between control and intervention groups. Parenting skills did not improve in the intervention group. This intervention to achieve healthy lifestyle changes in children via their parents as "change agents" was unsuccessful.

Challenges and results of a school-based intervention to manage excess weight among school children in Tunisia 2012-2014

BACKGROUND

Obesity is a serious health issue and predisposes individuals to an increased risk of morbidity and mortality. Its prevalence in children has increased worldwide.

OBJECTIVE

To demonstrate the feasibility and effectiveness of a school-based management program based on healthy lifestyle promotion for obese and overweight adolescents in Sousse, Tunisia.

METHODS

We conducted a quasi-experimental study among overweight and obese school children enrolled in 7th and 8th grades in Sousse, Tunisia with two groups, intervention and control. The 1-year intervention was based on promoting healthy eating and physical activity through a collective intervention for all recruited children and an individual intervention only for obese children who require intensive managing. Data collection was done before, at the end and at a 4-month follow up of the intervention, both in intervention and control groups.

RESULTS

The body mass index Z score decreased significantly from pre-intervention to post-intervention (1.89±0.57 to 1.76±0.63, p<0.001) and from post-intervention to the follow-up (1.76±0.63 to 1.55±0.68, p<0.001) in the intervention group. In the control group, it decreased significantly from pre-intervention to post-intervention but not significantly from post-intervention to follow-up assessment. Calorie intake decreased significantly both in intervention and control groups.

CONCLUSION

This project began with introducing a new culture of health management in schools on one side and with increasing awareness of the importance of obesity prevention and treatment. The support of authorities for this type of action is very important to guarantee its sustainability.

Diet, physical activity and behavioural interventions for the treatment of overweight or obese children from the age of 6 to 11 years

BACKGROUND

Child and adolescent overweight and obesity has increased globally, and can be associated with significant short- and long-term health consequences. This is an update of a Cochrane review published first in 2003, and updated previously in 2009. However, the update has now been split into six reviews addressing different childhood obesity treatments at different ages.

OBJECTIVES

To assess the effects of diet, physical activity and behavioural interventions (behaviour-changing interventions) for the treatment of overweight or obese children aged 6 to 11 years.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, LILACS as well as trial registers ClinicalTrials.gov and ICTRP Search Portal. We checked references of studies and systematic reviews. We did not apply any language restrictions. The date of the last search was July 2016 for all databases.

SELECTION CRITERIA

We selected randomised controlled trials (RCTs) of diet, physical activity, and behavioural interventions (behaviour-changing interventions) for treating overweight or obese children aged 6 to 11 years, with a minimum of six months' follow-up. We excluded interventions that specifically dealt with the treatment of eating disorders or type 2 diabetes, or included participants with a secondary or syndromic cause of obesity.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened references, extracted data, assessed risk of bias, and evaluated the quality of the evidence using the GRADE instrument. We contacted study authors for additional information. We carried out meta-analyses according to the statistical guidelines in the Cochrane Handbook for Systematic Reviews of Interventions.

MAIN RESULTS

We included 70 RCTs with a total of 8461 participants randomised to either the intervention or control groups. The number of participants per trial ranged from 16 to 686. Fifty-five trials compared a behaviour-changing intervention with no treatment/usual care control and 15 evaluated the effectiveness of adding an additional component to a behaviour-changing intervention. Sixty-four trials were parallel RCTs, and four were cluster RCTs. Sixty-four trials were multicomponent, two were diet only and four were physical activity only interventions. Ten trials had more than two arms. The overall quality of the evidence was low or very low and 62 trials had a high risk of bias for at least one criterion. Total duration of trials ranged from six months to three years. The median age of participants was 10 years old and the median BMI z score was 2.2.Primary analyses demonstrated that behaviour-changing interventions compared to no treatment/usual care control at longest follow-up reduced BMI, BMI z score and weight. Mean difference (MD) in BMI was -0.53 kg/m2 (95% confidence interval (CI) -0.82 to -0.24); P < 0.00001; 24 trials; 2785 participants; low-quality evidence. MD in BMI z score was -0.06 units (95% CI -0.10 to -0.02); P = 0.001; 37 trials; 4019 participants; low-quality evidence and MD in weight was -1.45 kg (95% CI -1.88 to -1.02); P < 0.00001; 17 trials; 1774 participants; low-quality evidence.Thirty-one trials reported on serious adverse events, with 29 trials reporting zero occurrences RR 0.57 (95% CI 0.17 to 1.93); P = 0.37; 4/2105 participants in the behaviour-changing intervention groups compared with 7/1991 participants in the comparator groups). Few trials reported health-related quality of life or behaviour change outcomes, and none of the analyses demonstrated a substantial difference in these outcomes between intervention and control. In two trials reporting on minutes per day of TV viewing, a small reduction of 6.6 minutes per day (95% CI -12.88 to -0.31), P = 0.04; 2 trials; 55 participants) was found in favour of the intervention. No trials reported on all-cause mortality, morbidity or socioeconomic effects, and few trials reported on participant views; none of which could be meta-analysed.As the meta-analyses revealed substantial heterogeneity, we conducted subgroup analyses to examine the impact of type of comparator, type of intervention, risk of attrition bias, setting, duration of post-intervention follow-up period, parental involvement and baseline BMI z score. No subgroup effects were shown for any of the subgroups on any of the outcomes. Some data indicated that a reduction in BMI immediately post-intervention was no longer evident at follow-up at less than six months, which has to be investigated in further trials.

AUTHORS' CONCLUSIONS

Multi-component behaviour-changing interventions that incorporate diet, physical activity and behaviour change may be beneficial in achieving small, short-term reductions in BMI, BMI z score and weight in children aged 6 to 11 years. The evidence suggests a very low occurrence of adverse events. The quality of the evidence was low or very low. The heterogeneity observed across all outcomes was not explained by subgrouping. Further research is required of behaviour-changing interventions in lower income countries and in children from different ethnic groups; also on the impact of behaviour-changing interventions on health-related quality of life and comorbidities. The sustainability of reduction in BMI/BMI z score and weight is a key consideration and there is a need for longer-term follow-up and further research on the most appropriate forms of post-intervention maintenance in order to ensure intervention benefits are sustained over the longer term.

Predictors of Short- and Long-Term Attrition From the Parents as Agents of Change Randomized Controlled Trial for Managing Pediatric Obesity

INTRODUCTION

Attrition in pediatric weight management is a substantial problem. This study examined factors associated with short- and long-term attrition from a lifestyle and behavioral intervention for parents of children with overweight or obesity.

METHOD

Fifty-two families with children ages 6 to 12 years old and body mass index at or above the 85th percentile participated in a randomized controlled trial focused on parents, comparing parent-based cognitive behavioral therapy with parent-based psychoeducation for pediatric weight management. We examined program attrition using two clinical phases of the intervention: short-term and long-term attrition, modeled using the general linear model. Predictors included intervention type, child/parent weight status, sociodemographic factors, and health of the family system.

RESULTS

Higher self-assessed health of the family system was associated with lower short-term attrition; higher percentage of intervention sessions attended by parents was associated with lower long-term attrition.

DISCUSSION

Different variables were significant in our short- and long-term models. Attrition might best be conceptualized based on short- and long-term phases of clinical, parent-based interventions for pediatric weight management.

Using Intervention Mapping to develop the Parents as Agents of Change (PAC©) intervention for managing pediatric obesity

Background

Pediatric obesity has become increasingly prevalent over recent decades. In view of the psychosocial and physical health risks, and the high likelihood that children with obesity will grow to become adults with obesity, there is a clear need to develop evidence-based interventions that can be delivered in the health care system to optimize the health and well-being of children with obesity and their families. The aim of this paper is to describe the development, implementation, and planned evaluation of a parent-based weight management intervention designed for parents of 8–12 year olds with obesity.

Methods/results

The principles of Intervention Mapping (IM) were used to develop an intervention called Parents as Agents of Change (PAC^©). From 2006 to 2009, an environmental scan plus qualitative (individual interviews with parents and children), quantitative (medical record reviews), and literature review data were collected to gain broad insight into family factors related to pediatric obesity and its management. Theoretical frameworks and empirical evidence guided curriculum development, which was founded primarily on the tenets of family systems theory and cognitive behavioral theory. PAC was developed as a manualized, 16-session, group-based, health care professional-led intervention for parents to address individual, family, and environmental factors related to the management of pediatric obesity. The intervention was refined based on feedback from local and international experts, and has been implemented successfully in a multi-disciplinary weight management centre in a children’s hospital.

Conclusion

IM provided a practical framework to guide the systematic development of a pediatric weight management intervention for parents of children with obesity. This logical, step-by-step process blends theory and practice and is broadly applicable in the context of obesity management intervention development and evaluation. Following intervention development, the PAC intervention was evaluated within a randomized clinical trial.

A Community-Based Nutrition and Physical Activity Intervention for Children Who Are Overweight or Obese and Their Caregivers

There is a need for efficacious interventions to reduce the prevalence of childhood obesity, and a limited body of research suggests that collaborative community-based programs designed for children and their caregivers may be effective in reducing obesity rates. This paper reports the results of a community-based obesity intervention, South County Food, Fitness and Fun (SCFFF), designed for preadolescent children who are overweight or obese and their caregivers. SCFFF was developed in response to community concerns. Families were referred to the program by their physician and participated in the program at no cost. The 16-week intervention includes weekly group nutrition and physical activity sessions. Analyses determined that 65 out of the 97 children who completed SCFFF provided 2-year follow-up data and had reduced BMI z-scores over 2 years following the intervention. These participants decreased their energy, fat, carbohydrate, saturated fat, and sodium intake and increased core body strength and endurance from baseline to the end of the intervention. SCFFF was effective in reducing relative weight and improving diet and core muscle strength and endurance in children who are overweight or obese.

A Call to Action: Setting the Research Agenda for Addressing Obesity and Weight-Related Topics in Children with Physical Disabilities

BACKGROUND

Pediatric obesity is a world-wide challenge. Children with physical disabilities are particularly at risk of obesity, which is worrisome because obesity can result in serious secondary conditions that decrease health status, reduce independence, and increase impact on healthcare systems. However, the determinants of obesity and the health promotion needs of children with physical disabilities are relatively unexplored compared with their typically developing peers.

METHODS

This white paper describes a Canadian multi-stakeholder workshop on the topic of obesity and health in children with physical disabilities and provides recommendations for future research in this understudied area.

RESULTS

Seventy-one knowledge gaps identified by attendees using a modified nominal group technique clustered into six themes: (1) early, sustained engagement of families; (2) rethinking determinants of obesity and health; (3) maximizing impact of research; (4) inclusive integrated interventions; (5) evidence-informed measurement and outcomes; and (6) reducing weight biases. Attendees worked together to develop research plans in more detail for three areas identified through consensus as high priority: "early, sustained engagement of families;" "rethinking determinants of obesity and health;" and "evidence informed measurement and outcomes."

CONCLUSIONS

Using the workshop described here as a call to action, Canadian researchers are now well positioned to work toward a greater understanding of weight-related topics in children with physical disabilities, with the aim of developing evidence-based and salient obesity prevention and treatment approaches.

Parent-only interventions for childhood overweight or obesity in children aged 5 to 11 years

BACKGROUND

Child and adolescent overweight and obesity have increased globally, and are associated with short- and long-term health consequences.

OBJECTIVES

To assess the efficacy of diet, physical activity and behavioural interventions delivered to parents only for the treatment of overweight and obesity in children aged 5 to 11 years.

SEARCH METHODS

We performed a systematic literature search of databases including the Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL and LILACS as well trial registers. We checked references of identified trials and systematic reviews. We applied no language restrictions. The date of the last search was March 2015 for all databases.

SELECTION CRITERIA

We selected randomised controlled trials (RCTs) of diet, physical activity and behavioural interventions delivered to parents only for treating overweight or obesity in children aged 5 to 11 years.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for risk of bias and evaluated overall study quality using the GRADE instrument. Where necessary, we contacted authors for additional information.

MAIN RESULTS

We included 20 RCTs, including 3057 participants. The number of participants ranged per trial between 15 and 645. Follow-up ranged between 24 weeks and two years. Eighteen trials were parallel RCTs and two were cluster RCTs. Twelve RCTs had two comparisons and eight RCTs had three comparisons. The interventions varied widely; the duration, content, delivery and follow-up of the interventions were heterogeneous. The comparators also differed. This review categorised the comparisons into four groups: parent-only versus parent-child, parent-only versus waiting list controls, parent-only versus minimal contact interventions and parent-only versus other parent-only interventions.Trial quality was generally low with a large proportion of trials rated as high risk of bias on individual risk of bias criteria.In trials comparing a parent-only intervention with a parent-child intervention, the body mass index (BMI) z score change showed a mean difference (MD) at the longest follow-up period (10 to 24 months) of -0.04 (95% confidence interval (CI) -0.15 to 0.08); P = 0.56; 267 participants; 3 trials; low quality evidence. In trials comparing a parent-only intervention with a waiting list control, the BMI z score change in favour of the parent-only intervention at the longest follow-up period (10-12 months) had an MD of -0.10 (95% CI -0.19 to -0.01); P = 0.04; 136 participants; 2 trials; low quality evidence. BMI z score change of parent-only interventions when compared with minimal contact control interventions at the longest follow-up period (9 to 12 months) showed an MD of 0.01 (95% CI -0.07 to 0.09); P = 0.81; 165 participants; 1 trial; low quality evidence. There were few similarities between interventions and comparators across the included trials in the parent-only intervention versus other parent-only interventions and we did not pool these data. Generally, these trials did not show substantial differences between their respective parent-only groups on BMI outcomes.Other outcomes such as behavioural measures, parent-child relationships and health-related quality of life were reported inconsistently. Adverse effects of the interventions were generally not reported, two trials stated that there were no serious adverse effects. No trials reported on all-cause mortality, morbidity or socioeconomic effects.All results need to be interpreted cautiously because of their low quality, the heterogeneous interventions and comparators, and the high rates of non-completion.

AUTHORS' CONCLUSIONS

Parent-only interventions may be an effective treatment option for overweight or obese children aged 5 to 11 years when compared with waiting list controls. Parent-only interventions had similar effects compared with parent-child interventions and compared with those with minimal contact controls. However, the evidence is at present limited; some of the trials had a high risk of bias with loss to follow-up being a particular issue and there was a lack of evidence for several important outcomes. The systematic review has identified 10 ongoing trials that have a parent-only arm, which will contribute to future updates. These trials will improve the robustness of the analyses by type of comparator, and may permit subgroup analysis by intervention component and the setting. Trial reports should provide adequate details about the interventions to be replicated by others. There is a need to conduct and report cost-effectiveness analyses in future trials in order to establish whether parent-only interventions are more cost-effective than parent-child interventions.

The influence of parent's body mass index on peer selection: an experimental approach using virtual reality

Relatively little is known about the influence of psychosocial factors, such as familial role modeling and social network on the development and maintenance of childhood obesity. We investigated peer selection using an immersive virtual reality environment. In a virtual schoolyard, children were confronted with normal weight and overweight avatars either eating or playing. Fifty-seven children aged 7-13 participated. Interpersonal distance to the avatars, child's BMI, self-perception, eating behavior and parental BMI were assessed. Parental BMI was the strongest predictor for the children's minimal distance to the avatars. Specifically, a higher mothers' BMI was associated with greater interpersonal distance and children approached closer to overweight eating avatars. A higher father's BMI was associated with a lower interpersonal distance to the avatars. These children approached normal weight playing and overweight eating avatar peers closest. The importance of parental BMI for the child's social approach/avoidance behavior can be explained through social modeling mechanisms. Differential effects of paternal and maternal BMI might be due to gender specific beauty ideals. Interventions to promote social interaction with peer groups could foster weight stabilization or weight loss in children.

Families' Perceptions of and Experiences Related to a Pediatric Weight Management Intervention: A Qualitative Study

OBJECTIVE

To examine parents' and children's perceptions of and experiences related to a Parents as Agents of Change (PAC) intervention for managing pediatric obesity.

METHODS

Ten families were recruited from a PAC intervention. Participants were interviewed before (10 adults and 9 children), during (9 adults and 8 children), and after (8 adults) the intervention.

RESULTS

Before the intervention, families reported goals to increase physical activity, plan and eat healthier meals, reduce screen time, and lose weight. During the intervention, families described different approaches to making behavior changes depending on who assumed responsibility (parent, child, or shared responsibility). After the intervention, group setting, goal setting, and portion size activities were viewed positively. Suggestions for improvement included engaging children and reducing intervention length.

CONCLUSIONS AND IMPLICATIONS

Practitioners delivering PAC interventions should discuss families' goals and concerns, and who is responsible for making lifestyle changes. Practical activities are valuable. The length of interventions and engagement of children should be considered.

Lifestyle therapy for the treatment of youth with type 2 diabetes

Type 2 diabetes (T2D) in youth is a relatively novel condition facing paediatric health care providers. Few experimental trials exist to guide clinical management in this population. Supporting and prescribing modifiable lifestyle behaviours is cornerstone in the management of T2D in adults. Clinical trials in obese adolescents suggest that intensive lifestyle interventions that include both dietary changes and increased physical activity elicit clinically meaningful reductions in weight and improve cardiovascular risk profiles. Observational studies in youth with T2D suggest that better diet quality and increased physical activity are associated with better metabolic control; however, the limited experimental data available does not support these observations. Trials evaluating lifestyle monotherapy for the treatment of hyperglycaemia in youth with T2D do not exist, and the only study evaluating combined lifestyle and pharmacologic therapy did not show additional benefit over pharmacologic treatment with metformin alone. Physiological and psychosocial differences between youth and adults with T2D likely contribute to the differences in the effectiveness of lifestyle therapy for improving glycaemic control. The current review describes these topics in detail and provides recommendations for paediatric health care providers for the promotion of lifestyle therapy for the management of hyperglycaemia and cardiovascular risk factors for youth with T2DM.

Controlling childhood obesity: A systematic review on strategies and challenges

BACKGROUND

Childhood obesity is a global health problem with short- and long-term health consequences. This systematic review presents a summary of the experiences on different family-, school-, and clinic-based interventions.

MATERIALS AND METHODS

Electronic search was conducted in MEDLINE, PubMed, ISI Web of Science, and Scopus scientific databases. We included those studies conducted among obese individuals aged up to 18 years. Our search yielded 105 relevant papers, 70 of them were conducted as high quality clinical trials.

RESULTS

Our findings propose that school-based programs can have long-term effects in a large target group. This can be related to this fact that children spend a considerable part of their time in school, and adopt some parts of lifestyle there. They have remarkable consequences on health behaviors, but as there are some common limitations, their effects on anthropometric measures are not clear. Due to the crucial role of parents in development of children's behaviors, family-based interventions are reported to have successful effects in some aspects; but selection bias and high dropout rate can confound their results. Clinic-based interventions revealed favorable effects. They include dietary or other lifestyle changes like increasing physical activity or behavior therapy. It seems that a comprehensive intervention including diet and exercise are more practical. When they have different designs, results are controversial.

CONCLUSION

We suggest that among different types of interventional programs, a multidisciplinary approach in schools in which children's family are involved, can be the best and most sustainable approach for management of childhood obesity.

Characterizing severe obesity in children and youth referred for weight management

Background

Severe obesity (SO) in pediatrics has become increasing prevalent in recent decades.

The objective of our study was to examine differences in demographic, anthropometric, cardiometabolic, and lifestyle variables in children and youth with SO versus their less overweight/obese (OW/OB) peers.

Methods

A retrospective medical record review of 6-19 year old participants enrolled in an outpatient pediatric weight management clinic was conducted. SO (body mass index [BMI] ≥99^th percentile) and OW/OB (BMI ≥85^th and <99^th percentile) groups were created according to Centers for Disease Control and Prevention definitions. Demographic, anthropometric, cardiometabolic and lifestyle data reported at baseline (pre-intervention) were retrieved.

Results

Of the 345 participants, most were girls (56.2%), Caucasian (78.7%), and had family incomes > $50,000/year (65.7%). The SO group (n = 161) had lower HDL-cholesterol and higher liver enzymes, insulin resistance and blood pressure than the OW/OB group (n = 184; all p < 0.01). They also reported higher total energy intakes, fewer steps/day, less moderate-to-vigorous physical activity, and more leisure time screen time (all p < 0.02) than their leaner peers. Compared to the OW/OB group, a higher proportion of individuals in the SO group possessed cardiometabolic risk factors, including high triglycerides (45.8% vs 58.5%), alanine aminotransferase (55.4% vs 81.4%), insulin resistance (55.6% vs 82.1%), systolic blood pressure (11.5% vs 27.3%), diastolic blood pressure (17.8% vs 30.0%), and low HDL-cholesterol (44.6% vs 64.6%; all p < 0.02). Aside from the ~75% of participants (groups combined) who met the daily recommended intakes of grain and meat products, <50% of boys and girls met any of the remaining nutrition and physical activity-related recommendations. Compared to the OW/OB group, greater proportions of children and youth in the SO group failed to meet moderate-to-vigorous physical activity (48.4% vs 31.9%) and leisure-time-screen-time recommendations (43.4% vs 28.3%; both p < 0.05).

Conclusion

Children and youth with SO have a worse cardiometabolic profile and less favorable lifestyle habits than their OW/OB peers. These differences emphasize the heightened obesity-related health risks associated with SO in the pediatric years.

Modest treatment effects and high program attrition: The impact of interdisciplinary, individualized care for managing paediatric obesity

BACKGROUND

There is an urgent need to identify effective weight management interventions in real-world, clinical settings to improve the health of children with obesity.

OBJECTIVES

To determine the impact of individualized, interdisciplinary care on the weight status of children with obesity; to assess the relationship between clinical interactions and change in participants' weight status; and to document the degree of program attrition.

METHODS

A retrospective medical record review of clinical and administrative data from a paediatric weight management clinic in Edmonton, Alberta, was performed, which included data from a group of five- to 18-year-olds (body mass index [BMI] ≥85th percentile) collected from 2008 to 2012. Demographic, anthropometric and attendance data were retrieved from baseline and follow-up at three-, seven- and 11-month timepoints. The primary outcomes were participants' BMI z-score and change in BMI z-score over time.

RESULTS

Data from 165 individuals were included. Among those with follow-up anthropometric data, weight stabilization occurred at three (n=127) and seven months (n=84). For individuals with follow-up anthropometric data at 11 months (n=44), BMI z-score tended to decrease over time (-0.05±0.12 units; P=0.06). Program attrition increased over time (23%, 49% and 73% at three-, seven- and 11-month follow-ups, respectively). Between presentation and three-month follow-up, there was an inverse relationship between the number of clinical appointments attended and change in BMI z-score (r= -0.18; P=0.04), an association that became nonsignificant at seven and 11 months (both P>0.05).

CONCLUSION

An individualized, interdisciplinary weight management intervention led to weight stabilization and a modest weight reduction in children with obesity. Strategies to minimize program attrition are needed to optimize family engagement in care and success in managing paediatric obesity.

Participatory action research in the implementing process of evidence-based intervention to prevent childhood obesity: project design of the "Healthy Future" study

OBJECTIVE

To describe the design of the developmental project Healthy Future that aims to implement a new evidence-based program for the prevention of childhood obesity and collaboration and sharing of work between specialist and community health care professionals in parts of a county in western Norway.

METHODS

Comprehensive participatory planning and evaluation (CPPE) process as an action-oriented research approach was chosen, using mixed data sources, mixed methods, and triangulation.

DISCUSSION

A bottom-up approach might decrease the barriers when new evidence-based childhood prevention interventions are going to be implemented. It is crucial not only to build partnership and shared understanding, motivation, and vision, but also to consider the frames of the organizations, such as competencies, and time to carry out the interventions at the right level of health care service and adapt to the overweight children and their families needs.

CONCLUSION

The developmental process of new health care programs is complex and multileveled and requires a framework to guide the process. By CPPE approach evidence-based health care practice can be delivered based on research, user knowledge, and provider knowledge in the field of childhood overweight and obesity in a certain context.
