Family therapy as a model for treating childhood obesity: useful tools for clinicians

Family-based physical activity interventions and family functioning: A systematic review

Family physical activity (PA) can confer multiple health benefits, yet whether PA interventions affect general family functioning has not been appraised. The purpose of this review was to evaluate studies that have examined the effect of family PA interventions, where child PA was the focus of the intervention, on constructs of family functioning. Literature searches were concluded on January 11, 2022 using seven common databases. Eligible studies were in English, utilized a family PA intervention, and assessed a measure of family functioning as a study outcome. The initial search yielded 8413 hits, which was reduced to 20 independent PA interventions of mixed quality after screening for eligibility criteria. There was mixed evidence for whether family PA interventions affected overall family functioning; however, analyses of subdomains indicated that family cohesion is improved by PA interventions when children are in the early school years (aged 5-12). High-quality studies also showed an impact of family PA interventions on family organization. Targeted interventions at specific family subsystems (e.g., father-son, mother-daughter), characteristics (low-income, clinical populations, girls), and broad multibehavioral interventions may have the most reliable effects. Overall, the findings show that family PA interventions can promote family cohesion and organization, particularly among families with children in the early school years. Higher quality research, employing randomized trial designs and targeting specific intervention and sample characteristics (e.g., different clinical conditions, specific parent-child dyads), is recommended in order to better ascertain the effectiveness of these approaches.

Rethinking family-based obesity treatment

Emerging research in paediatric obesity has demonstrated that parental involvement in the weight management process can improve weight outcomes in children. Recent guidelines by the American Academy of Pediatrics note the importance of parent and family involvement in treatment. However, it is currently unknown if including the entire family in obesity treatment can supersede outcomes associated with participation of only one parent. Family Systems Theory (FST) provides the theoretical foundation for examining one's healthy behaviours as they exist within the context of their family, defined by family dynamics. This narrative review aims to reconsider prior definitions of paediatric family-based management using the FST framework to be inclusive of family and household diversity and in doing so, inform research not only within weight management but also other domains of clinical care requiring family support or change. Applying FST to paediatric weight management highlights the link between family dynamics and paediatric obesity, demonstrating the association of dysfunctional family dynamics with more severe obesity. While family-based weight management remains the gold standard for treatment of paediatric obesity, more investigation is needed in expanding family-based interventions to impact entire families and potentially improve outcomes more broadly for overall family health and wellbeing.

Child and adolescent obesity

The prevalence of child and adolescent obesity has plateaued at high levels in most high-income countries and is increasing in many low-income and middle-income countries. Obesity arises when a mix of genetic and epigenetic factors, behavioural risk patterns and broader environmental and sociocultural influences affect the two body weight regulation systems: energy homeostasis, including leptin and gastrointestinal tract signals, operating predominantly at an unconscious level, and cognitive-emotional control that is regulated by higher brain centres, operating at a conscious level. Health-related quality of life is reduced in those with obesity. Comorbidities of obesity, including type 2 diabetes mellitus, fatty liver disease and depression, are more likely in adolescents and in those with severe obesity. Treatment incorporates a respectful, stigma-free and family-based approach involving multiple components, and addresses dietary, physical activity, sedentary and sleep behaviours. In adolescents in particular, adjunctive therapies can be valuable, such as more intensive dietary therapies, pharmacotherapy and bariatric surgery. Prevention of obesity requires a whole-system approach and joined-up policy initiatives across government departments. Development and implementation of interventions to prevent paediatric obesity in children should focus on interventions that are feasible, effective and likely to reduce gaps in health inequalities.

Parents' recalled experiences of the child centred health dialogue in children with overweight: a qualitative study

BACKGROUND

Because overweight and obesity are still increasing and prevention of childhood obesity is more likely to be effective when initiated in preschool children, the Child Health Service in the south of Sweden developed a structured child-centred health dialogue model targeting all 4-year-old children and their families. The aim of this study was to describe parents' recalled experiences of this health dialogue in children with overweight.

METHODS

A qualitative inductive approach with purposeful sampling was used. Thirteen individual interviews with parents (including 11 mothers and 3 fathers) were conducted and analysed with qualitative content analysis.

RESULTS

The analysis resulted in two categories: 'A valuable visit with a subtle individual impact' that described parents' recalled experiences of the health dialogue and 'There is a complex interaction between weight and lifestyle' that reflected the parents' perceptions of the relationship between their children's weight and lifestyle.

CONCLUSIONS

Parents recalled the child-centred health dialogue as important and described discussing a healthy lifestyle as one of the obligations of the Child Health Service. Parents wanted confirmation that their family lifestyle was healthy; however, they did not want to discuss the relationship between their family lifestyle and their children's weight. Parents expressed that when their child followed the child's growth curve, then this indicated healthy growth. This study supports using the child-centred health dialogue as a model to provide structure for discussing a healthy lifestyle and growth but highlights the difficulties of discussing body mass index and overweight, especially in the presence of children.

Childhood obesity: A review of current and future management options

Obesity is becoming increasingly prevalent in paediatric populations worldwide. In addition to increasing prevalence, the severity of obesity is also continuing to rise. Taken together, these findings demonstrate a worrying trend and highlight one of the most significant challenges to public health. Childhood obesity affects multiple organs in the body and is associated with both significant morbidity and ultimately premature mortality. The prevalence of complications associated with obesity, including dyslipidaemia, hypertension, fatty liver disease and psychosocial complications are becoming increasingly prevalent within the paediatric populations. Treatment guidelines currently focus on intervention with lifestyle and behavioural modifications, with pharmacotherapy and surgery reserved for patients who are refractory to such treatment. Research into adult obesity has established pharmacological novel therapies, which have been approved and established in clinical practice; however, the research and implementation of such therapies in paediatric populations have been lagging behind. Despite the relative lack of widespread research in comparison to the adult population, newer therapies are being trialled, which should allow a greater availability of treatment options for childhood obesity in the future. This review summarizes the current evidence for the management of obesity in terms of medical and surgical options. Both future therapeutic agents and those which cause weight loss but have an alternative indication are also included and discussed as part of the review. The review summarizes the most recent research for each intervention and demonstrates the potential efficacy and limitations of each treatment option.

A child-centered health dialogue for the prevention of obesity in child health services in Sweden - A randomized controlled trial including an economic evaluation

BACKGROUND

Prevention of child obesity is an international public health priority and believed to be effective when started in early childhood. Caregivers often ask for an early and structured response from health professionals when their child is identified with overweight, yet cost-effective interventions for children aged 2-6 years and their caregivers in Child Health Services are lacking.

OBJECTIVES

To evaluate the effects and cost-effectiveness of a child-centered health dialogue in the Child Health Services in Sweden on 4-year-old children with normal weight and overweight.

METHODS

Thirty-seven Child Health Centers were randomly assigned to deliver intervention or usual care. The primary outcome was zBMI-change.

RESULTS

A total of 4598 children with normal weight (zBMI: 0.1 [SD = 0.6] and 490 children with overweight (zBMI: 1.6 [SD = 0.3]) (mean age: 4.1 years [SD = 0.1]; 49% females) were included. At follow-up, at a mean age of 5.1 years [SD = 0.1], there was no intervention effect on zBMI-change for children with normal weight. Children with overweight in the control group increased zBMI by 0.01 ± 0.50, while children in the intervention group decreased zBMI by 0.08 ± 0.52. The intervention effect on zBMI-change for children with overweight was -0.11, with a 95% confidence interval of -0.24 to 0.01 (p = 0.07). The estimated additional costs of the Child-Centered Health Dialogue for children with overweight were 167 euros per child with overweight and the incremental cost-effectiveness ratio was 183 euros per 0.1 zBMI unit prevented.

CONCLUSIONS

This low-intensive multicomponent child-centered intervention for the primary prevention of child obesity did not show statistical significant effects on zBMI, but is suggested to be cost-effective with the potential to be implemented universally in the Child Health Services. Future studies should investigate the impact of socio-economic factors in universally implemented obesity prevention programs.

Child-Centred Health Dialogue for primary prevention of obesity in Child Health Services - a feasibility study

Aims: The aim of this study was to test a Child-Centred Health Dialogue model for primary prevention of obesity for 4-year-old children in Child Health Services, for its feasibility and the responsiveness of its outcomes. Methods: A feasibility study was set up with a non-randomised quasi-experimental cluster design comparing usual care with a structured multicomponent Child-Centred Health Dialogue consisting of two parts: (1) a universal part directed to all children and (2) a targeted part for families where the child is identified with overweight. Results: In total, 203 children participated in Child-Centred Health Dialogue while 582 children received usual care. Nurses trained in the model were able to execute both the universal health dialogue and the targeted part of the intervention. Tutorship enabled the nurses to reflect on and discuss their experiences, which strengthened their confidence and security. One year after the intervention fewer normal-weight 4-year-olds in the intervention group had developed overweight at the age of five compared with the control group, and none had developed obesity. The difference in overweight prevalence at follow-up did not reach statistical significance. Conclusions: This study demonstrates that a child-centred, multicomponent, interactive intervention for the promotion of healthy lifestyles and primary prevention of obesity for all 4-year-old children participating in Child Health Services is feasible on a small scale. As almost all caregivers make use of Child Health Services in Sweden, the findings should be confirmed in a randomised controlled trial before the intervention can be implemented on a larger scale.

A challenging balancing act to engage children and their families in a healthy lifestyle - Nurses' experiences of child-centred health dialogue in child health services in Sweden

AIMS AND OBJECTIVES

To describe nurses' experiences of a child-centred family guided intervention of obesity tested within the child health services targeting children identified with overweight and their caregivers.

BACKGROUND

Interventions aiming to support families towards a healthier lifestyle can lead to decreased risk of overweight evolving into obesity in a child. At the same time, nurses have found dialogues on weight challenging and may therefore avoid them.

DESIGN

Qualitative descriptive inductive design following content analysis applying to the COREQ guidelines.

METHODS

Content analysis was used to analyse 13 individual semi-structured interviews with nurses in the child health service in Sweden after completed training in CCHD, including how to facilitate the dialogue with the use of illustrations.

RESULTS

The theme Health dialogue about weight is a challenging balancing act facilitated by a supportive intervention emerged through eight subcategories in three main categories. Nurses experienced that CCHD with children identified with overweight and their caregivers provoked an emotional response both for themselves and for the caregivers of the child. The training in child-centred health dialogues promoted the nurses' work with structure and professionalism, as the nurses carefully took tentative steps to engage the family for a healthy lifestyle.

CONCLUSIONS

Emotional and practical challenges in performing CCHD still remained among nurses after customised training, which might comprise the child's rights to be involved in his or her own care when the child was identified as overweight. However, training for nurses, including lectures and tutorials, was found to increase the quality and professionalism of performing CCHD by providing structure, tools and tutorial support.

RELEVANCE TO CLINICAL PRACTICE

Customised training and illustrations can support nurses when performing a structured intervention such as child-centred health dialogues.

U.S. Children and Youth's Physical Activities Inside and Outside of School PE: 1985 vs. 2012

The purpose of this study was, by taking advantage of the rich data from two U.S. national fitness surveys, to examine the physical activity (PA) students engaged in, both inside and outside school physical education (PE), determine if there are differences by grade, sex, and weight status, and if there was a change between 1985 and 2012. The data from the 1985 National Children and Youth Fitness Study (NCYFS) and the 2012 NHANES National Youth Fitness Survey (NNYFS) were matched, merged (N = 6178, 3107 boys and 3071 girls), and analyzed. It was found that basketball remained the most popular PA inside school PE across both surveys. Swimming was the most popular PA outside of school PE in 1985, but was replaced by running in 2012. Although PA taught and promoted inside of school PE and that such PA practiced outside were moderately correlated across the surveys, some disconnections were noticed. The impact of grade, sex, and weight status on PA preference and participation was also confirmed. What is needed is to the design and integration of more lifelong and individual PAs in future school PE curricula and school and community children and youth sport and PA programs.

Psychotherapy versus treatment as usual and other control interventions in children and adolescents with overweight and obesity: a protocol for systematic review with meta-analysis and Trial Sequential Analysis

INTRODUCTION

The prevalence of children with overweight and obesity is increasing worldwide. Multicomponent interventions incorporating diet, physical activity and behavioural change have shown limited improvement to body mass index (BMI). However, the impact of psychotherapy is poorly explored. This systematic review aims to assess the effects of psychotherapeutic approaches for children with all degrees of overweight.

METHODS AND ANALYSIS

We will include randomised clinical trials involving children and adolescents between 0 and 18 years with overweight and obesity, irrespective of publication type, year, status or language up to April 2020. Psychotherapy will be compared with no intervention; wait list control; treatment as usual; sham psychotherapy or pharmaceutical placebo. The following databases will be searched: Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, MEDLINE, Embase, PsycINFO, PubMed, Web of Science, CINAHL and LILACS. Primary outcomes will be BMI z-score, quality of life measured by a validated scale and proportion of patients with serious adverse events. Secondary outcomes will be body weight, self-esteem, anxiety, depression and proportion of patients with non-serious adverse events. Exploratory outcomes will be body fat, muscle mass and serious adverse events. Study inclusion, data extraction and bias risk assessments will be conducted independently by at least two authors. We will assess risk of bias according to Cochrane guidelines and the Cochrane Effective Practice and Organisation of Care guidance. We will use meta-analysis and control risks of random errors with Trial Sequential Analysis. The quality of the evidence will be assessed using Grading of Recommendations Assessment, Development and Evaluation Tool. The systematic review will be reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Cochrane guidelines.

ETHICS AND DISSEMINATION

As individual patient data will not be included, we do not require ethics approval. This review will be published in a peer review journal.

Development of a consensus statement on the role of the family in the physical activity, sedentary, and sleep behaviours of children and youth

BACKGROUND

Children and youth who meet the physical activity, sedentary, and sleep behaviour recommendations in the Canadian 24-Hour Movement Guidelines are more likely to have desirable physical and psychosocial health outcomes. Yet, few children and youth actually meet the recommendations. The family is a key source of influence that can affect lifestyle behaviours. The purpose of this paper is to describe the process used to develop the Consensus Statement on the Role of the Family in the Physical Activity, Sedentary, and Sleep Behaviours of Children and Youth (0-17 years) and present, explain, substantiate, and discuss the final Consensus Statement.

METHODS

The development of the Consensus Statement included the establishment of a multidisciplinary Expert Panel, completion of six reviews (three literature, two scoping, one systematic review of reviews), custom data analyses of Statistics Canada's Canadian Health Measures Survey, integration of related research identified by Expert Panel members, a stakeholder consultation, establishment of consensus, and the development of a media, public relations, communications and launch plan.

RESULTS

Evidence from the literature reviews provided substantial support for the importance of family on children's movement behaviours and highlighted the importance of inclusion of the entire family system as a source of influence and promotion of healthy child and youth movement behaviours. The Expert Panel incorporated the collective evidence from all reviews, the custom analyses, other related research identified, and stakeholder survey feedback, to develop a conceptual model and arrive at the Consensus Statement: Families can support children and youth in achieving healthy physical activity, sedentary and sleep behaviours by encouraging, facilitating, modelling, setting expectations and engaging in healthy movement behaviours with them. Other sources of influence are important (e.g., child care, school, health care, community, governments) and can support families in this pursuit.

CONCLUSION

Family is important for the support and promotion of healthy movement behaviours of children and youth. This Consensus Statement serves as a comprehensive, credible, and current synopsis of related evidence, recommendations, and resources for multiple stakeholders.

No additional long-term effect of group vs individual family intervention in the treatment of childhood obesity-A randomised trial

AIM

Long-term evaluations of childhood obesity treatments are needed. We examined changes in weight and cardiometabolic risk 1 year after children completed individual family or group-based weight management interventions.

METHODS

In 2009-2010, 6- to 12-year-old children with overweight or obesity from Finnmark and Troms (Norway) were recruited after media coverage and randomised to 24 months of individual family (n = 49) or group intervention (n = 48). Individual family intervention included counselling by a paediatric hospital team and a public health nurse in the local community. Group intervention included meetings with other families and a multidisciplinary hospital team, weekly physical activity sessions and a family camp. The primary outcome body mass index (BMI) and cardiometabolic risk factors were analysed 12 months after intervention.

RESULTS

From baseline to 36 months, children's BMI increased 3.0 kg/m² in individual family and 2.1 kg/m² in group intervention (between-group -0.9kg/m² , P = 0.096). Data were available from 62 children (64%). Between-group differences in C peptide (P = 0.01) were detected in favour of group intervention. Pooled data from both treatment groups showed continued decrease in BMI standard deviation score (P < 0.001).

CONCLUSION

No between-group difference in BMI was observed 12 months after intervention. Both groups combined showed sustained decrease in BMI standard deviation score.

Obesity Management in Adolescents: Comparison of a Low-Intensity Face-to-Face Therapy Provided by a Trained Paediatrician with an Intensive Multidisciplinary Group Therapy

OBJECTIVE

This study aimed to compare the effects of a low-intensity face-to-face therapy provided by a trained paediatrician to an intensive group therapy provided by a multidisciplinary team on the BMI of adolescents with obesity.

METHODS

This longitudinal cohort study included 233 adolescents aged 11-18 years (mean 13.1 ± 1.7 years). Patients and their parents choose either a low-intensity face-to-face therapy or an intensive group therapy (total 88 h).

RESULTS

At baseline, the mean BMI was 29.4 ± 4.9 kg/m2. Within groups changes of BMI z-scores were significant at the end of follow-up both in the face-to-face (-0.2 ± 0.5) and the group therapy (-0.24 ± 0.5). There was no difference among groups. Younger age (12-14 years), gender, follow-up duration as well as BMI z-score at inclusion were significantly related to BMI z-score changes, independently of the type of intervention. As expected, the face-to-face therapy was far less expensive than the group therapy (USD 1,473.00 ± 816.00 vs. USD 6,473.00 ± 780.00).

CONCLUSION

A low-intensity face-to-face therapy resulted in similar changes of the BMI z-score of adolescents than an intensive multidisciplinary group therapy. This approach could be easily disseminated in primary care settings with a specific training in obesity care.

Family Perceptions of a Family-Based Pediatric Obesity Treatment Program

Objective. To better understand families’ perceptions of a family-inclusive pediatric obesity treatment program. Methods. We sought the perspectives of families actively and inactively enrolled in a family-based pediatric obesity treatment program via semistructured interviews. Responses were analyzed by an inductive thematic approach. Results. Twenty-three families participated. Families reported appreciation for program resources and recognized positive changes in family functioning. Logistical issues were reported as major barriers to participation and the primary reason for dropout. Work was perceived as the main barrier to participation for fathers. Families preferred addressing health behaviors in a structured environment. Siblings recognized changes within the family. Conclusions. Families consistently recognized barriers to participation and observed positive influences on family function. Insights were gained from the perspectives of various family members, suggesting that obesity treatment programs could affect the health of multiple family members.

Health in overweight children: 2-year follow-up of Finnmark Activity School--a randomised trial

OBJECTIVE

To compare a comprehensive lifestyle intervention for overweight children performed in groups of families with a conventional single-family treatment. Two-year follow-up data on anthropometric and psychological outcome are presented.

DESIGN

Overweight and obese children aged 6-12 years with body mass index (BMI) corresponding to ≥27.5 kg/m(2) in adults were randomised to multiple-family (n=48) or single-family intervention (n=49) in a parallel design. Multiple-family intervention comprised an inpatient programme with other families and a multidisciplinary team, follow-up visits in their hometown, weekly physical activity and a family camp. Single-family intervention included counselling by paediatric nurse, paediatric consultant and nutritionist at the hospital and follow-up by a community public health nurse. Primary outcome measures were change in BMI kg/m(2) and BMI SD score after 2 years.

RESULTS

BMI increased by 1.29 kg/m(2) in the multiple-family intervention compared with 2.02 kg/m(2) in the single-family intervention (p=0.075). BMI SD score decreased by 0.20 units in the multiple-family group and 0.08 units in the single-family intervention group (p=0.046). A between-group difference of 2.4 cm in waist circumference (p=0.038) was detected. Pooled data from both treatment groups showed a significant decrease in BMI SD score of 0.14 units and a significant decrease in parent-reported and self-reported Strength and Difficulty Questionnaire total score of 1.9 units.

CONCLUSIONS

Two-year outcome showed no between-group difference in BMI. A small between-group effect in BMI SD score and waist circumference favouring multiple-family intervention was detected. Pooled data showed an overall improvement in psychological outcome measures and BMI SD score.

Evidence update on the treatment of overweight and obesity in children and adolescents

Childhood obesity is associated with increased medical and psychosocial consequences and mortality and effective interventions are urgently needed. Effective interventions are urgently needed. This article reviews the evidence for psychological treatments of overweight and obesity in child and adolescent populations. Studies were identified through searches of online databases and reference sections of relevant review articles and meta-analyses. Treatment efficacy was assessed using established criteria, and treatments were categorized as well-established, probably efficacious, possibly efficacious, experimental, or of questionable efficacy. Well-established treatments included family-based behavioral treatment (FBT) and Parent-Only Behavioral Treatment for children. Possibly efficacious treatments include Parent-Only Behavioral Treatment for adolescents, FBT-Guided Self-Help for children, and Behavioral Weight Loss treatment with family involvement for toddlers, children, and adolescents. Appetite awareness training and regulation of cues treatments are considered experimental. No treatments are considered probably efficacious, or of questionable efficacy. All treatments considered efficacious are multicomponent interventions that include dietary and physical activity modifications and utilize behavioral strategies. Treatment is optimized if family members are specifically targeted in treatment. Research supports the use of multicomponent lifestyle interventions, with FBT and Parent-Only Behavioral Treatment being the most widely supported treatment types. Additional research is needed to test a stepped care model for treatment and to establish the ideal dosage (i.e., number and length of sessions), duration, and intensity of treatments for long-term sustainability of healthy weight management. To improve access to care, the optimal methods to enhance the scalability and implementability of treatments into community and clinical settings need to be established.

Current approaches to the management of pediatric overweight and obesity

OPINION STATEMENT

Family-based behavioral intervention has been demonstrated to be an effective and safe treatment for childhood obesity and should be considered a first-line treatment option. However, access to such intensive evidence-based treatment is limited and, currently, obesity care is dominated by high intensity behavioral treatment implemented in specialty clinics or less effective low intensity treatments implemented in primary care. However, capitalizing on the established and ongoing relationship between primary care providers and families, primary care providers have an invaluable role in early identification of overweight and obesity, and subsequent referral to an evidence-based treatment. Key aspects of effective treatment include: early intervention, moderate intensity to high intensity intervention of sufficient duration, multicomponent intervention targeting dietary modification, physical activity and behavioral strategies, family involvement and goals targeting family members, and follow-up contact during maintenance. The purpose of this review is to present the current empirically supported treatment options for pediatric obesity including primary care-based interventions and diagnostic tools, multicomponent behavioral intervention with a focus on family-based behavioral intervention, immersion treatment, and pharmacologic and surgical management.

Beyond BMI: The Next Chapter in Childhood Obesity Management

Pediatric obesity treatment has traditionally focused on body mass index (BMI) and has had limited success. Recent research has suggested new ways to approach this topic that focuses more on holistic measures of health and inclusion of a larger population of children. This paper discusses new evidence in the prevention of chronic disease and treatment of obesity that has a body positive and mental health lens as well as integrating research from several areas of health, including the prevention of chronic disease. Practical medical and mental health assessments tools are suggested for clinical use. Implications for an individualized, positive treatment future are presented.

Single versus multiple-family intervention in childhood overweight--Finnmark Activity School: a randomised trial

OBJECTIVE

To compare a new comprehensive lifestyle programme performed in groups of families with overweight (included obese) children with a more conventional single-family programme. The study design and interim anthropometrical results after 12 months are presented.

DESIGN

Altogether 97 overweight and obese children aged 6-12 years with body mass index (BMI) corresponding to cut-off point ≥ 27.5 in adults were included. Study participants were randomised to multiple-family intervention (MUFI) or single-family intervention (SIFI) in a parallel design. MUFI comprised a 3-day inpatient programme at the hospital with other families and a multidisciplinary team, follow-up visits in their hometown individually and in groups, organised physical activity twice weekly and a 4-day family camp after 6 months. SIFI comprised individual counselling by paediatric nurse, paediatric consultant and nutritionist at the hospital and follow-up by public health nurse in the community. Solution focused approach was applied in both interventions. Primary outcome measures were change in BMI kg/m(2) and BMI SD score (BMI SDS).

RESULTS

BMI increased by 0.37 units in the MUFI compared to 0.77 units in the SIFI (p=0.18). BMI SDS decreased by 0.16 units in the MUFI group compared to 0.07 units in the SIFI group (p=0.07). Secondary endpoint waist circumference decreased 0.94 cm in the multiple-family group and increased 0.95 cm in the single-family group, p=0.04.

CONCLUSIONS

Interim analysis after 12 months showed no between-group difference in terms of BMI or BMI SDS. The MUFI group had a significant decrease in waist circumference compared to the SIFI group.

Changes in parents' time use and its relationship to child obesity

OBJECTIVE

The aim was to explore any change in parents' time use together with their children, changes in their perceived occupational value, and its relationship to children's body mass index (BMI) over the course of a one-year occupation-focused family intervention.

METHOD

The study sample consisted of participants in one arm of a randomized controlled trial, involving mothers and fathers (n = 30) of 17 children aged 4-6 years who were considered obese. Data were collected by time-geographical diaries during the intervention and by measuring the parents' occupational value and the children's BMI before and after the intervention.

RESULTS

At the end of the intervention, an increase was shown in the amount of time parents spent together with their children during weekdays (p = .042) and the parents perceived occupational value (p = .013). Children's BMI z-score changed with -0.11 units.

CONCLUSION

Collaboration with parents may be useful in interventions aiming at facilitating a normal weight development among children.

School based interventions versus family based interventions in the treatment of childhood obesity- a systematic review

BACKGROUND

The prevalence of childhood obesity, which has seen a rapid increase over the last decade, is now considered a major public health problem. Current treatment options are based on the two important frameworks of school- and family-based interventions; however, most research has yet to compare the two frameworks in the treatment of childhood obesity.The objective of this review is to compare the effectiveness of school-based intervention with family-based intervention in the treatment of childhood obesity.

METHODS

Databases such as Medline, Pub med, CINAHL, and Science Direct were used to execute the search for primary research papers according to inclusion criteria. The review included a randomised controlled trial and quasi-randomised controlled trials based on family- and school-based intervention frameworks on the treatment of childhood obesity.

RESULTS

The review identified 1231 articles of which 13 met the criteria. Out of the thirteen studies, eight were family-based interventions (n = 8) and five were school-based interventions (n = 5) with total participants (n = 2067). The participants were aged between 6 and 17 with the study duration ranging between one month and three years. Family-based interventions demonstrated effectiveness for children under the age of twelve and school-based intervention was most effective for those aged between 12 and 17 with differences for both long-term and short-term results.

CONCLUSIONS

The evidence shows that family- and school-based interventions have a considerable effect on treating childhood obesity. However, the effectiveness of the interventional frameworks depends on factors such as age, short- or long-term outcome, and methodological quality of the trials. Further research studies are required to determine the effectiveness of family- and school-based interventions using primary outcomes such as weight, BMI, percentage overweight and waist circumference in addition to the aforementioned factors.

Switching From Originator to Biosimilar Human Growth Hormone Using Dialogue Teamwork: Single-Center Experience From Sweden

Introduction

A new treatment plan was implemented at Skåne University Hospital, on economic grounds, for children requiring recombinant human growth hormone (rhGH) treatment. This involved switching patients from treatment with originator rhGHs to treatment with a biosimilar rhGH, somatropin (Omnitrope^®), using a Dialogue Teamwork approach. The feasibility of using this approach to implement the switch of treatment was assessed, as well as the impact of the switch on treatment efficacy and cost of therapy.

Methods

As part of the Dialogue Teamwork approach, patients/parents received several opportunities for dialogue and sources of information, including discussions with the Head of Department, the responsible physician and a specialized endocrinology nurse. Height and height standard deviation score (HSDS) data were plotted for each individual patient (N = 98). A modeling approach was also used, to predict growth after switching to biosimilar rhGH; the predictions were then compared to the actual observed height after the switch. Costs to the clinic of rhGH therapy were calculated between May–August 2009 and May–August 2012.

Results

Of the 102 patients offered the switch, 98 accepted. Height and HSDS data indicated there was no negative impact on growth velocity after the switch to biosimilar rhGH. Modeling demonstrated that observed growth following the switch was consistent with predicted growth based on data before patients were switched. There were no reports of serious or unexpected adverse drug reactions following the switch to biosimilar rhGH. Following the switch, the cost to the clinic of rhGH treatment decreased from approximately 6 million SEK (May–August 2009) to approximately 4 million SEK (May–August 2012). This corresponds to an annual saving of 6 million SEK (€650,000).

Conclusion

Patients were successfully switched from originator to biosimilar rhGH (somatropin), with no negative impact on growth, and no serious or unexpected adverse drug reactions. The switch from originator to biosimilar rhGH is associated with substantial cost savings.

An individual, community-based treatment for obese children and their families: the solution-focused approach

BACKGROUND

This study evaluates an individual, community-based treatment for obese children and their families. In this program, a treatment team applied solution-focused techniques to develop a custom-made treatment plan in collaboration with the participants. The treatment plan consisted of community-based lifestyle activities.

METHODS

559 obese children with an average BMI z-score of 2.76 ± 0.54 took part in the 12-month study, and 372 children with an average BMI z-score of 2.75 ± 0.52 took part in the 24-month study. At the start of the study, ethnicity and special school needs were recorded. Before, after 12 months, and after 24 months of the treatment, body weight and height were measured. The effect of the treatment on body weight was evaluated using BMI z-scores.

RESULTS

291 children (52%) completed 12 months of treatment, whereas 22 children (4%) were dismissed earlier due to a good response. After 12 months, the children showed a significant decrease in BMI z-score by 0.16 (95% confidence interval (CI) 0.11-0.20; p < 0.005). After 24 months, 103 children (28%) were participating in the program, with a significant decrease in BMI z-score of 0.15 (95% CI 0.07-0.22; p < 0.005). 50 children (13%) were dismissed before the end of the second year due to significant weight loss (standard deviation z-score reduction -0.38; 95% CI 0.30-0.46; p < 0.005; with an average treatment duration of 12.9 ± 6.4 months). There was a negative correlation of age and reduction in BMI z-score: children younger than 6 years showed a decrease in BMI z-score of 0.45 (95% CI 0.26-0.65) and 0.31 (95% CI 0.11-0.53) after 12 and after 24 months, respectively.

CONCLUSIONS

Children showed a significant decrease in BMI z-score after the treatment. We found a negative correlation of age and weight loss. Special attention to patients with a high risk of drop-out might further improve these results. We advise a referral to obesity treatment as early as possible since a 'wait and see' policy might have adverse results in obese children.

Which psychological method is most effective for group treatment?

While outcome studies in pediatric obesity have received considerable attention, research on different components of effective interventions remains limited. Little is known which psychological method (i.e., behavior modification, cognitive behavior therapy and family therapy) is most useful or how the choice of program delivery (group/individual) influences the intervention outcomes. Group treatment is of particular interest for two reasons. First, motivation is important for behavior change; in group settings motivation can be increased in two ways: by the group leader and through the interaction with the group participants. Second, group treatment can be more cost-effective than individual approaches (i.e., it requires fewer staff resources and space). This paper aims to comment on the influence of the method choice and delivery in pediatric obesity interventions through discussion of the existing evidence on current programs. In addition, two examples of useful models will be described in more detail: the Yale Bright Bodies Weight Management Program and the Family Weight School. These are outpatients programs both targeting families with severely obese children but through different methodological approaches. Finally, directions for future research will be explored, particularly regarding how the selection of program delivery and psychological method affect treatment outcomes in various populations.

Modelling the relationship between obesity and mental health in children and adolescents: findings from the Health Survey for England 2007

A number of studies have reported significant associations between obesity and poor psychological wellbeing in children but findings have been inconsistent.

METHODS

This study utilised data from 3,898 children aged 5-16 years obtained from the Health Survey for England 2007. Information was available on Body Mass Index (BMI), parental ratings of child emotional and behavioural health (Strengths and Difficulties Questionnaire), self-reported physical activity levels and sociodemographic variables. A multilevel modelling approach was used to allow for the clustering of children within households.

RESULTS

Curvilinear relationships between both internalising (emotional) and externalising (behavioural) symptoms and adjusted BMI were observed. After adjusting for potential confounders the relationships between obesity and psychological adjustment (reported externalising and internalising symptoms) remained statistically significant. Being overweight, rather than obese, had no impact on overall reported mental health. 17% of children with obesity were above the suggested screening threshold for emotional problems, compared to 9% of non-obese children. Allowing for clustering and potential confounding variables children classified as obese had an odds ratio (OR) of 2.13 (95% CI 1.39 to 3.26) for being above the screening threshold for an emotional disorder compared to non-obese young people. No cross-level interactions between household income and the relationships between obesity and internalising or externalising symptoms were observed.

CONCLUSIONS

In this large, representative, UK-based community sample a curvilinear association with emotional wellbeing was observed for adjusted BMI suggesting the possibility of a threshold effect. Further research could focus on exploring causal relationships and developing targeted interventions.
