The effect of psychological interventions targeting overweight and obesity in school-aged children: a systematic review and meta-analysis. BMC Public Health 2023; 23:1478. [PMID: 37537523 PMCID: PMC10398924 DOI: 10.1186/s12889-023-16339-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Accepted: 07/18/2023] [Indexed: 08/05/2023] Open
Abstract
BACKGROUND Multi-component psychological interventions may mitigate overweight and obesity in children and adolescents. Evidence is, however, scattered on the effectiveness of such interventions. This study aims to review the available evidence on the effectiveness of multi-component psychological interventions on anthropometric measures of school-aged children with overweight or obesity. METHODS We systematically searched international databases/search engines including PubMed and NLM Gateway (for MEDLINE), Web of Science, SCOPUS, and Google Scholar up to November 2022 for relevant articles pertaining to psychological weight-loss interventions targeting school-aged children. Two reviewers screened and extracted pertinent data. The quality of included studies was assessed using the Cochrane Risk of Bias Tool for Randomized Trials. Random effect meta-analysis was used to calculate, and pool standardized mean differences (SMD). We distinguished between intervention and maintenance effects. Intervention effects were defined as the mean change in outcome measurement detected between baseline and post-treatment. Maintenance effects were defined as the mean change in outcome measurement between post-treatment and last follow-up. RESULTS Of 3,196 studies initially identified, 54 and 30 studies were included in the qualitative and quantitative syntheses, respectively. Most studies reported on group-based interventions. The significant effects of intervention on BMI z-score (SMD -0.66, 95% CI: -1.15, -0.17) and WC (SMD -0.53, 95% CI: -1.03, -0.04) were observed for interventions that centered on motivational interviewing and cognitive behavioral therapy, respectively. Mean BMI and WC did not differ significantly between post-treatment and last follow-up measurement (maintenance effect), indicating that an initial weight loss obtained through the intervention period could be maintained over time. CONCLUSIONS Findings indicate that motivational interviewing and cognitive behavioral therapy as interventions to reduce BMI z-score (generalized obesity) and waist circumference (abdominal obesity) are effective and durable. However, detailed analyses on individual components of the interventions are recommended in future effectiveness studies.

Sex differences in response to lifestyle intervention among children and adolescents: Systematic review and meta-analysis. Obesity (Silver Spring) 2023; 31:665-692. [PMID: 36762579 DOI: 10.1002/oby.23663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 10/28/2022] [Accepted: 10/28/2022] [Indexed: 02/11/2023]
Abstract
OBJECTIVE Little is known about sex differences in response to lifestyle interventions among pediatric populations. The purpose of this analysis was to evaluate sex differences in adiposity following lifestyle interventions among children and adolescents with overweight or obesity aged 6 to 18 years old. METHODS Searches were conducted in PubMed, Web of Science, and MEDLINE (from inception to March 2021), and references from included articles were examined. Eligibility criteria included children and adolescents aged 6 to 18 years with overweight or obesity, randomization to a lifestyle intervention versus a control group, and assessment of at least one adiposity measure. Corresponding authors were contacted to obtain summary statistics by sex (n = 14/49). RESULTS Of 89 full-text articles reviewed, 49 (55%) were included, of which 33 (67%) reported statistically significant intervention effects on adiposity. Only two studies (4%) evaluated sex differences in response to lifestyle intervention, reporting conflicting results. The results of the meta-regression models demonstrated no significant differences in the treatment effect between male and female youth for weight (beta = -0.05, SE = 0.18, z = -0.28, p = 0.8), BMI (beta = 0.03, SE = 0.14, z = 0.19, p = 0.85), BMI z score (beta = -0.04, SE = 0.18, z = -0.23, p = 0.82), percentage body fat (beta = -0.11, SE = 0.16, z = -0.67, p = 0.51), and waist circumference (beta = -0.30, SE = 0.25, z = -1.18, p = 0.24). CONCLUSIONS The meta-analysis revealed that youth with overweight or obesity do not demonstrate a differential response to lifestyle intervention in relation to adiposity-related outcomes.

Effectiveness of lifestyle interventions for treatment of overweight/obesity among children in China: A systematic review and meta-analysis. Front Endocrinol (Lausanne) 2022; 13:972954. [PMID: 36387871 PMCID: PMC9659900 DOI: 10.3389/fendo.2022.972954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Accepted: 10/17/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Pediatric obesity has become a global public health problem. China has the largest population of obese children in the world. It is important to develop effective interventions to control child obesity. This systematic review summarizes proof from randomized controlled trials to assess the efficacy of lifestyle intervention to reduce BMI and metabolic risk factors for overweight/obese Chinese children. METHODS We searched studies from five databases (PubMed, MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and CNKI). Research that meets the following requirements was included: randomized controlled trials, participants are overweight/obese Chinese children aged <18 years old, and the effectiveness of lifestyle interventions is evaluated. RESULTS Eight randomized controlled trials were included. A significant difference was found between the intervention group and the control group for the BMI changes (mean difference = -1.49; 95% CI: -2.20 to -0.77; p < 0.001). Subgroup analyses consistently demonstrated that effects of lifestyle interventions on BMI change including multiple-component interventions (mean difference = -2.03 kg/m2; 95% CI: -3.62 to -0.43; p < 0.001) were stronger than those only with physical activities or health education; effects of lifestyle interventions on BMI change were also strengthened if duration of intervention last for more than 1 year (mean difference = -3.03 kg/m2; 95% CI: -4.00 to -2.06; p = 0.01) or with age during 12-18 years old (mean difference = -1.90 kg/m2; 95% CI: -3.37 to -0.43; p < 0.001). CONCLUSIONS Lifestyle interventions are effective in reducing BMI in Chinese children with overweight/obesity, and the effectiveness is more profound when the lifestyle intervention includes multiple components, lasts longer than one year, and/or is conducted among teens. These findings provide an important evidence base for developing and implementing potentially effective lifestyle interventions for the treatment of overweight/obesity among Chinese children.

Development of a School-Based Intervention to Increase Physical Activity Levels Among Chinese Children: A Systematic Iterative Process Based on Behavior Change Wheel and Theoretical Domains Framework. Front Public Health 2021; 9:610245. [PMID: 33987160 PMCID: PMC8110714 DOI: 10.3389/fpubh.2021.610245] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Accepted: 03/16/2021] [Indexed: 12/29/2022] Open
Abstract
Regular physical activity has a range of benefits for children's health, academic achievement, and behavioral development, yet they face barriers to participation. The aim of the study was to systematically develop an intervention for improving Chinese children's physical activity participation, using the Behavior Change Wheel (BCW) and Theoretical Domains Framework (TDF). The BCW and TDF were used to (i) understand the behavior (through literature review), (ii) identify intervention options (through the TDF-intervention function mapping table), (iii) select content and implementation options [through behavior change technique (BCT) taxonomy and literature review], and (iv) finalize the intervention content (through expert consultation, patient and public involvement and engagement, and piloting). A systematic iterative process was followed to design the intervention by following the steps recommended by the BCW. This systematic process identified 10 relevant TDF domains to encourage engagement in physical activity among Chinese children: knowledge, memory, attention and decision processes, social influences, environmental context and resources, beliefs about capabilities, beliefs about consequences, social/professional role and identity, emotions, and physical skills. It resulted in the selection of seven intervention functions (education, persuasion, environmental restricting, modeling, enablement, training, and incentivization) and 21 BCTs in the program, delivered over a period of 16 weeks. The BCW and TDF allowed an in-depth consideration of the physical activity behavior among Chinese children and provided a systematic framework for developing the intervention. A feasibility study is now being undertaken to determine its acceptability and utility.

Abstract
OBJECTIVE To determine whether 12-month BMI SDS reductions persisted at 24 months in a multi-disciplinary assessment and intervention program for children and adolescents with obesity, and whether secondary outcomes improved. METHODS This was a community-based 12-month RCT in Aotearoa/New Zealand. Eligible participants were aged 5 to 16 years with BMI ≥98th centile or BMI >91st centile with weight-related comorbidities. The low-intensity control received comprehensive home-based baseline assessments and advice, and 6-monthly follow-up. The high-intensity intervention received the same assessments and advice, but also weekly multidisciplinary sessions. Primary outcome was BMI SDS at 12 months. Secondary outcomes included cardiovascular and metabolic markers. RESULTS 121 participants (60% of participants at baseline) were assessed at 24 months. BMI SDS reduction at 12 months was lost at 24 months in the modified intention-to-treat analysis [Control -0.03 (95%CI -0.14, 0.09) and Intervention -0.02 (-0.12, 0.08); P = .93]. However, sweet drink intake was reduced, water intake increased, and there were improvements in cardiovascular fitness in the high-intensity intervention. ≥70% attendance in the high-intensity intervention resulted in a persistent BMI SDS reduction of -0.22 after 24 months (95%CI -0.38, -0.06). CONCLUSIONS This trial was negative in terms of primary outcome at 24 months. However, high engagement led to sustained treatment effect, and there were multiple improvements in health measures.

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. BMJ Open 2020; 10:e036058. [PMID: 33154043 PMCID: PMC7646330 DOI: 10.1136/bmjopen-2019-036058] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2019] [Revised: 07/06/2020] [Accepted: 07/08/2020] [Indexed: 11/03/2022] Open
Abstract
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.

Abstract
The prevalence of in youth with overweight and obesity is a global health concern, necessitating clinical interventions to treat obesity effectively through lifestyle modification. Interventions in adolescents have demonstrated improvements in healthy eating and physical activity with only modest weight loss outcomes. Consequently, there is growing interest in developing strategies to enhance the effectiveness of clinical interventions in adolescents. Targeting the family system can be an effective approach, but existing studies have failed to examine the impact of co-enrolling both the adolescent and adult in individually tailored weight loss programs and coordinating the adolescent/adult weight loss efforts. PURPOSE This paper reports on the design and conceptual framework of the Dyad Plus study, which utilizes two weight loss clinics of the Wake Forest Baptist Medical Center: Brenner Families in training (Brenner FIT®; adolescents) and By Design (adults). Dyad Plus is a coordinated program designed to facilitate self-monitoring, positive communication, joint problem solving, and social support to increase physical activity, healthy eating, and weight loss relative to Brenner FIT alone. METHODS A total of 45 parent/adolescent dyads are randomized to one of three conditions (n = 15 for each): Brenner FIT only, Dyad (adolescent and parent both enroll simultaneously in the age appropriate program), and Dyad Plus (both parent and adolescent enroll simultaneously, but with a coordinated component for adolescent and caregiver). This study aims to develop and pilot the coordinated intervention, establish feasibility of the intervention, and determine costs associated with implementation. RESULTS The results of the study are expected in winter of 2021. CONCLUSION If proven feasible and acceptable, Dyad Plus will be tested for effectiveness in a large-scale implementation-effectiveness clinical trial.

Abstract
BACKGROUND Child and adolescent obesity is increasingly prevalent, and can be associated with significant short- and long-term health consequences. OBJECTIVES To assess the efficacy of lifestyle, drug and surgical interventions for treating obesity in childhood. SEARCH METHODS We searched CENTRAL on The Cochrane Library Issue 2 2008, MEDLINE, EMBASE, CINAHL, PsycINFO, ISI Web of Science, DARE and NHS EED. Searches were undertaken from 1985 to May 2008. References were checked. No language restrictions were applied. SELECTION CRITERIA We selected randomised controlled trials (RCTs) of lifestyle (i.e. dietary, physical activity and/or behavioural therapy), drug and surgical interventions for treating obesity in children (mean age under 18 years) with or without the support of family members, with a minimum of six months follow up (three months for actual drug therapy). 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 were excluded. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality and extracted data following the Cochrane Handbook. Where necessary authors were contacted for additional information. MAIN RESULTS We included 64 RCTs (5230 participants). Lifestyle interventions focused on physical activity and sedentary behaviour in 12 studies, diet in 6 studies, and 36 concentrated on behaviorally orientated treatment programs. Three types of drug interventions (metformin, orlistat and sibutramine) were found in 10 studies. No surgical intervention was eligible for inclusion. The studies included varied greatly in intervention design, outcome measurements and methodological quality.Meta-analyses indicated a reduction in overweight at 6 and 12 months follow up in: i) lifestyle interventions involving children; and ii) lifestyle interventions in adolescents with or without the addition of orlistat or sibutramine. A range of adverse effects was noted in drug RCTs. AUTHORS' CONCLUSIONS While there is limited quality data to recommend one treatment program to be favoured over another, this review shows that combined behavioural lifestyle interventions compared to standard care or self-help can produce a significant and clinically meaningful reduction in overweight in children and adolescents. In obese adolescents, consideration should be given to the use of either orlistat or sibutramine, as an adjunct to lifestyle interventions, although this approach needs to be carefully weighed up against the potential for adverse effects. Furthermore, high quality research that considers psychosocial determinants for behaviour change, strategies to improve clinician-family interaction, and cost-effective programs for primary and community care is required.

Family-based intervention using face-to-face sessions and social media to improve Malay primary school children's adiposity: a randomized controlled field trial of the Malaysian REDUCE programme. Nutr J 2018; 17:74.

Abstract
BACKGROUND Social media may be an effective medium by which parents could be trained to promote healthy eating behaviour and physical activity for their children. This trial evaluates the effectiveness of a family-based intervention using social media in combination with face-to-face sessions - the REDUCE (REorganise Diet, Unnecessary sCreen time and Exercise) programme - on adiposity of Malay children. METHODS Five primary schools in an urban area in Selangor, Malaysia participated in this two-arm randomized controlled field trial. Participants were parents (n = 134) and their primary school-going children 8-11 years of age who were either overweight or obese. These parent-child dyads were randomly allocated to intervention and wait-list control groups and were blinded to group assignment. The intervention was a four-week training programme using two face-to-face sessions and two Facebook sessions followed by weekly booster sessions over a three-month period using WhatsApp. The primary outcome was body mass index (BMI) z-score. Height, body weight, waist circumference and percentage of body fat were measured by blinded assessors. Data were collected at baseline (T1), immediately post-training (T2) and at three- (T3) and six-month post training (T4) and were analysed using generalized linear mixed modelling adjusted for covariates to estimate the intervention effects. Subgroup analysis was conducted for overweight and obese children. RESULTS Ninety-one percent of parents completed the study, 64 in intervention group and 58 in wait-list group. At the sixth month post-training, BMI z-scores were significantly reduced in the intervention group compared to the wait-list group, for the all children (overweight and obese children) and within the obese subgroup ((F(6, 517) = 2.817, p = 0.010) and (F(6, 297) = 6.072, p < 0.001) respectively. For waist circumference percentile and body fat percentage, the intervention group experienced a significant reduction compared to the wait-list group, within the obese subgroup ((F(6, 297) = 3.998, p = 0.001) and within the overweight subgroup (F(6, 201) = 2.526, p = 0.022). CONCLUSIONS The four-month REDUCE intervention programme was effective in reducing childhood adiposity. Further research using this approach needs to be conducted including cost-effectiveness studies before implementing it in a child obesity prevention programme.

Abstract
The increased prevalence of adolescent obesity and associated short-term and long-term complications emphasize the need for effective treatment. In this Review, we aim to describe the evidence for, and elements of, behaviour management and adjunctive therapies and highlight the opportunities and challenges presented by obesity management in adolescence. The broad principles of treatment include management of obesity-associated complications; a developmentally appropriate approach; long-term behaviour modification (dietary change, increased physical activity, decreased sedentary behaviours and improved sleep patterns); long-term weight maintenance strategies; and consideration of the use of pharmacotherapy, more intensive dietary therapies and bariatric surgery. Bariatric surgery should be considered in those with severe obesity and be undertaken by skilled bariatric surgeons affiliated with teams experienced in the medical and psychosocial management of adolescents. Adolescent obesity management strategies are more reliant on active participation than those for childhood obesity and should recognize the emerging autonomy of the patient. The challenges in adolescent obesity relate primarily to the often competing demands of developing autonomy and not yet having attained neurocognitive maturity.

Abstract
OBJECTIVE Studies have shown improvement in lipid levels after institution of lifestyle changes in children enrolled in closely monitored programs. There programs are difficult to mimic in real world clinics. We aim to determine if diet and exercise result in improvement in lipid levels in patients seen in a designated lipid clinic in a real life setting. DESIGN Retrospective review of patients followed for dyslipidemia at the Texas Children's Hospital Lipid Clinic from May 1, 2012 to May 1, 2015. Patients included were seen more than once, had repeat lipid testing, and abnormal baseline lipid levels. Multivariate analysis using mixed models were performed to compare outcomes in patients who did and did not participate in lifestyle change. RESULTS Of the 268 patients seen within the study period, 174 (56% male, 44% female) met inclusion criteria. Median age was 11 years. Compared to patients who did not make lifestyle changes: patients who made only diet changes demonstrated significant improvement in weight only (slope = -1.55, P-value = .014), and those who made only exercise changes demonstrated significant improvements in serum cholesterol (slope = -22.8, P-value = .017) and non-HDL cholesterol (slope = -28.7, P-value = < .01) levels. Patients who participated in both diet and exercise demonstrated significant improvement in weight (slope = -1.13, P-value = .011), diastolic blood pressure (slope = -1.82, P-value = < .01), and serum lipid levels: LDL (slope = -10.8, P-value = 0.017), HDL (slope = 1.52, P-value = .24), Triglycerides (slope = -0.11, P-value = .033) compared to those who did not make lifestyle changes. CONCLUSIONS Outpatient management of dyslipidemia is difficult. Only patients who participated in both diet and exercise showed significant improvement in outcomes when compared to those who did not make lifestyle changes.

Abstract
Childhood obesity is associated with type 2 diabetes mellitus. We aimed to determine the effects of lifestyle modification programs on fasting plasma glucose (FPG) levels in overweight children. We queried six relevant electronic databases and manually searched for studies published before December 2016. Overweight/obese children who underwent a lifestyle modification for more than 6 months were included. A total of 3923 children from eight randomized controlled trials (RCTs) were included. Compared with the control group, the lifestyle modification group had significantly lower FPG levels by 1.3 mg/dL. The mean differences were significantly decreased for both secondary outcomes; BMI z-score decreased by 0.16 units and insulin levels decreased by 2.4 mU/L. The metaregression showed that the follow-up duration was associated with FPG levels and BMI and insulin levels and half year is a suitable follow-up duration for this population. This study showed that lifestyle modification programs may be effective in reducing the FPG levels of overweight/obese children. Further high-quality RCTs with longer follow-up periods are needed to evaluate the long-term effect of this complementary approach for diabetes mellitus prevention on overweight/obese children.

Theoretical frameworks informing family-based child and adolescent obesity interventions: A qualitative meta-synthesis. Obes Res Clin Pract 2017; 11:627-639. [PMID: 28844833 DOI: 10.1016/j.orcp.2017.08.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2017] [Revised: 07/10/2017] [Accepted: 08/03/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Child and adolescent obesity trends are rising throughout the world, revealing treatment difficulties and a lack of consensus about treatment. The family system is broadly viewed as a potential setting for facilitation of behaviour change. Therefore, family-based interventions have come into focus. However, the use of theoretical frameworks to strengthen these interventions is rare and very uneven. OBJECTIVE AND METHOD To conduct a qualitative meta-synthesis of family-based interventions for child and adolescent obesity to identify the theoretical frameworks applied, thus understanding how theory is used in practice. A literature review was conducted between January and March 2016. A total of 35 family-based interventions were selected for analysis. RESULTS Eleven interventions explicitly stated that theory guided the development and were classified as theory-inspired. The social cognitive, self-efficacy and Family Systems Theory appeared most frequently. The remaining 24 were classified as theory-related as theoretical elements of self-monitoring; stimulus control, reinforcement and modelling were used. CONCLUSION The designs of family-based interventions reveal numerous inconsistencies and a significant void between research results and health care practice. Based on the analysis, this article proposes three themes to be used as focus points when designing future interventions and when selecting theories for the development of solid, theory-based frameworks for application. The themes are: (1) age of target group, (2) intervention objective, and (3) self-efficacy and readiness for change.

Abstract
BACKGROUND Adolescent overweight and obesity has increased globally, and can be associated with short- and long-term health consequences. Modifying known dietary and behavioural risk factors through behaviour changing interventions (BCI) may help to reduce childhood overweight and obesity. This is an update of a review published in 2009. OBJECTIVES To assess the effects of diet, physical activity and behavioural interventions for the treatment of overweight or obese adolescents aged 12 to 17 years. SEARCH METHODS We performed a systematic literature search in: CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, LILACS, and the trial registers ClinicalTrials.gov and ICTRP Search Portal. We checked references of identified studies and systematic reviews. There were no 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 for treating overweight or obesity in adolescents aged 12 to 17 years. DATA COLLECTION AND ANALYSIS Two review authors independently assessed risk of bias, evaluated the overall quality of the evidence using the GRADE instrument and extracted data following the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. We contacted trial authors for additional information. MAIN RESULTS We included 44 completed RCTs (4781 participants) and 50 ongoing studies. The number of participants in each trial varied (10 to 521) as did the length of follow-up (6 to 24 months). Participants ages ranged from 12 to 17.5 years in all trials that reported mean age at baseline. Most of the trials used a multidisciplinary intervention with a combination of diet, physical activity and behavioural components. The content and duration of the intervention, its delivery and the comparators varied across trials. The studies contributing most information to outcomes of weight and body mass index (BMI) were from studies at a low risk of bias, but studies with a high risk of bias provided data on adverse events and quality of life.The mean difference (MD) of the change in BMI at the longest follow-up period in favour of BCI was -1.18 kg/m2 (95% confidence interval (CI) -1.67 to -0.69); 2774 participants; 28 trials; low quality evidence. BCI lowered the change in BMI z score by -0.13 units (95% CI -0.21 to -0.05); 2399 participants; 20 trials; low quality evidence. BCI lowered body weight by -3.67 kg (95% CI -5.21 to -2.13); 1993 participants; 20 trials; moderate quality evidence. The effect on weight measures persisted in trials with 18 to 24 months' follow-up for both BMI (MD -1.49 kg/m2 (95% CI -2.56 to -0.41); 760 participants; 6 trials and BMI z score MD -0.34 (95% CI -0.66 to -0.02); 602 participants; 5 trials).There were subgroup differences showing larger effects for both BMI and BMI z score in studies comparing interventions with no intervention/wait list control or usual care, compared with those testing concomitant interventions delivered to both the intervention and control group. There were no subgroup differences between interventions with and without parental involvement or by intervention type or setting (health care, community, school) or mode of delivery (individual versus group).The rate of adverse events in intervention and control groups was unclear with only five trials reporting harms, and of these, details were provided in only one (low quality evidence). None of the included studies reported on all-cause mortality, morbidity or socioeconomic effects.BCIs at the longest follow-up moderately improved adolescent's health-related quality of life (standardised mean difference 0.44 ((95% CI 0.09 to 0.79); P = 0.01; 972 participants; 7 trials; 8 comparisons; low quality of evidence) but not self-esteem.Trials were inconsistent in how they measured dietary intake, dietary behaviours, physical activity and behaviour. AUTHORS' CONCLUSIONS We found low quality evidence that multidisciplinary interventions involving a combination of diet, physical activity and behavioural components reduce measures of BMI and moderate quality evidence that they reduce weight in overweight or obese adolescents, mainly when compared with no treatment or waiting list controls. Inconsistent results, risk of bias or indirectness of outcome measures used mean that the evidence should be interpreted with caution. We have identified a large number of ongoing trials (50) which we will include in future updates of this review.

Camp-based family treatment of childhood obesity: randomised controlled trial. Arch Dis Child 2017; 102:303-310. [PMID: 27806969 PMCID: PMC5466918 DOI: 10.1136/archdischild-2015-309813] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2015] [Revised: 10/03/2016] [Accepted: 10/11/2016] [Indexed: 12/18/2022]
Abstract
OBJECTIVE To compare the effectiveness of a 2-year camp-based family treatment programme and an outpatient programme on obesity in two generations. DESIGN Pragmatic randomised controlled trial. SETTING Rehabilitation clinic, tertiary care hospital and primary care. PATIENTS Families with at least one child (7-12 years) and one parent with obesity. INTERVENTIONS Summer camp for 2 weeks and 4 repetition weekends or lifestyle school including 4 days family education. Behavioural techniques motivating participants to healthier lifestyle. MAIN OUTCOME MEASURES Children: 2-year changes in body mass index (BMI) SD score (SDS). Parents: 2-year change in BMI. Main analyses: linear mixed models. RESULTS Ninety children (50% girls) were included. Baseline mean (SD) age was 9.7 (1.2) years, BMI 28.7 (3.9) kg/m2 and BMI SDS 3.46 (0.75). The summer-camp children had a lower adjusted estimated mean (95% CI) increase in BMI (-0.8 (-3.5 to -0.2) kg/m2), but the BMI SDS reductions did not differ significantly (-0.11 (-0.49 to 0.05)). The 2-year baseline adjusted BMI and BMI SDS did not differ significantly between summer-camp and lifestyle-school completers, BMI 29.8 (29.1 to 30.6) vs 30.7 (29.8 to 31.6) kg/m2 and BMI SDS 2.96 (2.85 to 3.08) vs 3.11 (2.97 to 3.24), respectively. The summer-camp parents had a small reduction in BMI (-0.9 (-1.8 to -0.03) vs -0.8 (-2.1 to 0.4) in the lifestyle-school group), but the within-group changes did not differ significantly (0.3 (-1.7 to 2.2)). CONCLUSIONS A 2-year family camp-based obesity treatment programme had no significant effect on BMI SDS in children with severe obesity compared with an outpatient family-based treatment programme. TRIAL REGISTRATION NUMBER NCT01110096.

Abstract
OBJECTIVE Multiple interventions are available to reduce excess body weight in children. We appraised the quality of evidence supporting each intervention and assessed the effectiveness on different obesity-related outcomes. METHODS We conducted a systematic search for systematic reviews of randomized controlled trials evaluating pediatric obesity interventions applied for ≥6 months. We assessed the quality of evidence for each intervention using GRADE (Grading of Recommendation, Assessment, Development, and Evaluation) approach. RESULTS From 16 systematic reviews, we identified 133 eligible randomized controlled trials. Physical activity interventions reduced systolic blood pressure and fasting glucose (low to moderate quality of evidence). Dietary interventions with low-carbohydrate diets had a similar effect to low-fat diets in terms of body mass index (BMI) reduction (moderate quality of evidence). Educational interventions reduced waist circumference, BMI, and diastolic blood pressure (low quality of evidence). Pharmacological interventions reduced BMI (metformin, sibutramine, orlistat) and waist circumference (sibutramine, orlistat) and increased high-density lipoprotein cholesterol (sibutramine) but also raised systolic and diastolic blood pressure (sibutramine). Surgical interventions (laparoscopic adjustable gastric banding, Roux-en-Y gastric bypass, sleeve gastrectomy) resulted in the largest BMI reduction (moderate quality of evidence). Combined interventions consisting of dietary modification, physical activity, behavioral therapy, and education significantly reduced systolic and diastolic blood pressure, BMI, and triglycerides. Combined parent-child interventions and parent-only interventions had similar effects on BMI (low quality of evidence). CONCLUSIONS Several childhood obesity interventions are effective in improving metabolic and anthropometric measures. A comprehensive multicomponent intervention, however, appears to have the best overall outcomes.

Abstract
OBJECTIVE To determine whether a 2-year family-based intervention using frequent contact and limited expert involvement was effective in reducing excessive weight compared with usual care. METHODS Two hundred and six overweight and obese (BMI ≥85th percentile) children aged 4 to 8 years were randomized to usual care (UC) or tailored package (TP) sessions at university research rooms. UC families received personalized feedback and generalized advice regarding healthy lifestyles at baseline and 6 months. TP families attended a single multidisciplinary session to develop specific goals suitable for each family, then met with a mentor each month for 12 months, and every third month for another 12 months to discuss progress and provide support. Outcome measurements (anthropometry, questionnaires, dietary intake, accelerometry) were obtained at 0, 12, and 24 months. RESULTS BMI at 24 months was significantly lower in TP compared with UC children (difference, 95% confidence interval: -0.34, -0.65 to -0.02), as was BMI z score (-0.12, -0.20 to -0.04) and waist circumference (-1.5, -2.5 to -0.5 cm). TP children consumed more fruit and vegetables (P = .038) and fewer noncore foods (P = .020) than UC children, and fewer noncore foods were available in the home (P = .002). TP children were also more physically active (P = .035). No differences in parental feeding practices, parenting, quality of life, child sleep, or behavior were observed. CONCLUSIONS Frequent, low-dose support was effective for reducing excessive weight in predominantly mild to moderately overweight children over a 2-year period. Such initiatives could feasibly be incorporated into primary care.

Abstract
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. TRIAL REGISTRATION NUMBER NCT00872807, http://www.clinicaltrials.gov.

Abstract
INTRODUCTION Parental obesity is a risk factor for childhood obesity. The aim of this study was to determine if parental obesity influences the adherence and success of obesity treatment in a hospital paediatric endocrinology clinic. MATERIAL AND METHODS An analytical, prospective, longitudinal study was conducted on obese children aged 4-14. An initial body mass index (BMI), and again at 6 months after receiving health, hygiene and dietary recommendations. Success was considered as a decrease of 0.5 in the BMI Z-score, and adherence to attending the 6-month review. Parental BMI was determined to identify overweight. The χ(2) test was used for qualitative variables and the T-Student test for quantitative (significance, p<<.05). RESULTS The study included 100 children (52 male), 9.9±2.7 years old, BMI 28.1± 4.5kg/m(2) and BMI Z-Score 3.11±0.98. (85% had a BMI Z-score>3). More than half (59%) of the children had one or both parents obese (41 fathers and 37 mothers were obese). Treatment was not adhered to by 25 children. Adherence was worse if both parents were obese OR 3.65 (1.3 to 10.5) (P<=.01) and adherence was better if the mother was not obese, although the father was (P=.01). The treatment had significant success in 40 patients. If the mother was the only obese one in the family, the possibility of treatment failure was greater OR 5.6 (1.4 to 22.4) (P<.01) CONCLUSIONS: A high percentage of children with severe obesity have obese parents. The mother has an important influence on adherence and response to treatment for the severely obese child.

Abstract
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.

Abstract
Background Home and school environments conducive for unhealthy eating and physical inactivity are precursors of obesity. The aim of this study is evaluation of the effectiveness of a multi-component school-based weight management programme for overweight and obese primary school children via a home-school joint venture. Methods This study made use of variety of behavioural modification strategies integrating into the Health Promoting School approach to promote healthy lifestyles. The participants were overweight and obese students aged between 8 and 12 from six participating schools. The interventions involved students attending ten 75 minutes after-school sessions and one 3-hour week-end session of practical interactive and fun activities on healthy eating and exercise, and meal plan together with parents and printed tailor-made management advices. Parents received an introductory seminar with 2 sets of specially designed exercise for their overweight children. The tools to measure bodyweight and fat percentage and standing height were bio-impedance body fat scale and a portable stadiometer. Self-administered questionnaire was used to measure knowledge, attitudes and behaviours. McNemar test was utilized to compare the proportions of behaviour changes within the same group to assess for the trends of changes. BMI z-score and body fat percentage of intervention participants at baseline, 4 month and 8 month were compared pair-wisely using tests of within subject contrasts in repeated measures ANOVA to assess for programme sustainability. Results Those students in the intervention group reduced their BMI z-score (-0.21, 95% CI -0.34 to -0.07, P = 0.003) and body fat (-2.67%, 95% CI -5.12 to -0.22, P = 0.033) compared to wait list control group with statistical significant, and the intervention group also had a significant reduction in BMI z-score (-0.06, 95% CI -0.11, -0.007, P = 0.028) and body fat (-1.71%, 95% CI, -3.44 to 0.02, P = 0.052) after a 4 month maintenance period. Improvement of dietary habits and positive attitudes towards exercise were observed among the intervention group. Conclusion School based weight management programme integrated into a Health Promoting School approach with improved school policies and environment in supporting individual skills of obese students and their parents appears to be a promising practice for sustaining weight control.

Controlling childhood obesity: A systematic review on strategies and challenges.

Abstract
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.

Abstract
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.

Abstract
Effective interventions are needed to address the growing epidemic of childhood obesity. In the past 35 years, family-based approach has gradually developed as a preferred intervention. This review aimed to examine the methodological rigour and treatment effectiveness of family-based interventions according to intervention types and theoretical orientations. A total of 15 randomized controlled trials (RCTs) of family-based lifestyle interventions for children and adolescents aged 2-19 years were included. The adapted Methodological Quality Rating Scales (MQRS) and a four-grade qualitative scoring scheme were adopted to evaluate the methodological rigour and the effectiveness of treatment, respectively. The average MQRS score was 7.93 out of 14 points. Ten of the 15 RCTs had well aligned their research questions with appropriate research methods. The overall short-term outcome of the15 RCTs were satisfactory with an average score of 3.1. Family-based interventions rooted in behaviour theory achieved better results than those theoretically connected to family systems theory in terms of treatment effectiveness. Results suggest future studies to improve the methodological design and continue to explore the potential of the family systems approach.

BACKGROUND Treatment of childhood obesity is difficult, and successful management may differ in various areas with different cultural backgrounds. The present study was conducted to assess the effect of lifestyle modification family-based intervention in young Iranian children. METHODS This field trial study was conducted in 2011 among 156 obese children in Tehran, Iran. They were randomly assigned to intervention and control groups. At baseline, anthropometric measurements and biochemical analysis were performed. The second and third phases consisted of training sessions for parents of the intervention group. At the fourth phase, there was no training program. In all four phases, questionnaires on demographic characteristics, lifestyle and food frequency were completed by interviewing with mothers, and biochemical analysis was repeated at the end of the study. RESULTS During the second and third phases of the study, weight and height increased significantly in both groups, although weight increased more slowly, and waist and hip circumferences was decreased in the intervention group. Serum triglycerides and cholesterol decreased significantly in the intervention group (P < 0.05). Analysis of food group consumption showed that in the intervention group, not only consumption of milk, dairy and nuts group increased significantly but also the corresponding figure decreased for bread and cereals, sugar and confectionery ingredients; moreover, the family's oil and fat consumption decreased significantly (P < 0.05). Watching TV and playing on the computer decreased significantly in the intervention group; however, walking time increased significantly in both groups (P < 0.05). CONCLUSIONS The family-based lifestyle program had limited but desirable effects on anthropometric and metabolic outcomes of the obese children. We suggest that a longer period of intervention may have more favorable results.

Are eating habits associated with physical fitness in primary school children? Eat Behav 2013; 14:83-6. [PMID: 23265408 DOI: 10.1016/j.eatbeh.2012.11.002] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2012] [Revised: 10/03/2012] [Accepted: 11/13/2012] [Indexed: 10/27/2022]
Abstract
OBJECTIVE Children's eating habits have mainly been related to anthropometric characteristics but less is known about their association with physical fitness. METHODS 278 French school children (131 boys and 147 girls) filled in eating habit questionnaires and completed anthropometric measurement (weight, height, skinfolds) and physical fitness tests. The 20-m Shuttle run test and the Squat Jump test were used to assess aerobic fitness and anaerobic (lower limb muscle power) fitness respectively. RESULTS Breakfast consumption was associated with both aerobic fitness (p<0.05) and lower limb muscle power (p<0.01) while snacking was negatively related to Squat Jump performances (p<0.05). There was no association between physical fitness and either the type of the consumed-beverages or TV watching during dinner and lunch meals. Cumulated unhealthy eating habits was negatively associated with CRF stages and lower limb muscle power performances (p<0.05). CONCLUSION French primary school children physical fitness is associated with their eating habits and decreases with the number of unhealthy eating behaviors cumulated.

Abstract
BACKGROUND AND OBJECTIVES The effects of lifestyle interventions on cardio-metabolic outcomes in overweight children have not been reviewed systematically. The objective of the study was to examine the impact of lifestyle interventions incorporating a dietary component on both weight change and cardio-metabolic risks in overweight/obese children. METHODS English-language articles from 1975 to 2010, available from 7 databases, were used as data sources. Two independent reviewers assessed articles against the following eligibility criteria: randomized controlled trial, participants overweight/obese and ≤18 years, comparing lifestyle interventions to no treatment/wait-list control, usual care, or written education materials. Study quality was critically appraised by 2 reviewers using established criteria; Review Manager 5.1 was used for meta-analyses. RESULTS Of 38 eligible studies, 33 had complete data for meta-analysis on weight change; 15 reported serum lipids, fasting insulin, or blood pressure. Lifestyle interventions produced significant weight loss compared with no-treatment control conditions: BMI (-1.25kg/m(2), 95% confidence interval [CI] -2.18 to -0.32) and BMI z score (-0.10, 95% CI -0.18 to -0.02). Studies comparing lifestyle interventions to usual care also resulted in significant immediate (-1.30kg/m(2), 95% CI -1.58 to -1.03) and posttreatment effects (-0.92 kg/m(2), 95% CI -1.31 to -0.54) on BMI up to 1 year from baseline. Lifestyle interventions led to significant improvements in low-density lipoprotein cholesterol (-0.30 mmol/L, 95% CI -0.45 to -0.15), triglycerides (-0.15 mmol/L, 95% CI -0.24 to -0.07), fasting insulin (-55.1 pmol/L, 95% CI -71.2 to -39.1) and blood pressure up to 1 year from baseline. No differences were found for high-density lipoprotein cholesterol. CONCLUSIONS Lifestyle interventions can lead to improvements in weight and cardio-metabolic outcomes. Further research is needed to determine the optimal length, intensity, and long-term effectiveness of lifestyle interventions.

Abstract
OBJECTIVE This study examined the 24-month outcomes of a randomized controlled trial of a group-based behavioral weight control (BWC) program combined with either activity-based peer intervention or aerobic exercise. METHODS At baseline, 118 obese adolescents (68% female; BMI = 31.41 ± 3.33) ages 13 to 16 years (mean = 14.33; SD = 1.02) were randomized to receive 1 of 2 weight loss interventions. Both interventions received the same 16-week group-based cognitive-behavioral treatment, combined with either aerobic exercise or peer-based adventure therapy. Eighty-nine adolescents (75% of original sample) completed the 24-month follow-up. Anthropometric and psychosocial measures were obtained at baseline, at the end of the 16-week intervention, and at 12 and 24 months following randomization. RESULTS An intent-to-treat mixed factor analysis of variance indicated a significant effect for time on both percent over 50th percentile BMI for age and gender and standardized BMI score, with no differences by intervention group. Post hoc comparisons showed a significant decrease in percent overweight at 4 months (end of treatment), which was maintained at both 12- and 24-month follow-up visits. Significant improvements on several dimensions of self-concept were noted, with significant effects on physical appearance self-concept that were maintained through 24 months. CONCLUSIONS Both BWC conditions were effective at maintaining reductions in adolescent obesity and improvements in physical appearance self-concept through 24-month follow-up. This study is one of the first to document long-term outcomes of BWC intervention among adolescents.

Abstract
BACKGROUND Childhood obesity is associated with adverse changes in cardiometabolic risk factors. A family-oriented group program stressing a health-promoting lifestyle has been more effective than routine counselling in the treatment of obesity in school children. The aim of the present study was to compare the impact of group program and routine councelling on body composition and metabolic profile, and to evaluate the associations of changes in adiposity with levels of cardiometabolic risk factors. METHODS Seventy obese prepubertal children were randomized into family-oriented group program (15 sessions for parents and children) and routine counselling (2 appointments for children). Body mass index (BMI), body composition and different metabolic risk factors were assessed before and after the 6-month intervention. RESULTS Waist/height decreased more in the children attending the group treatment, but there were no significant differences between treatment arms in the changes of metabolic risk factors. When the arms were analyzed as combined, serum triglycerides decreased significantly if BMI standard deviation score (BMI-SDS) decreased ≥ 0.5. Serum fasting insulin decreased if BMISDS decreased ≥ 0.25. CONCLUSIONS Obesity-related metabolic risk factors reduced in prepubertal children if BMI-SDS decreased substantially. This result was not dependent on which intervention, family-oriented group program or routine counselling, was used.

Abstract
CONTEXT To aid translation of childhood obesity interventions evidence into practice, research studies must report results in a way that better supports pragmatic decision making. The current review evaluated the extent to which information on key external validity dimensions, participants, settings, interventions, outcomes, and maintenance of effects, was included in research studies on behavioral treatments for childhood obesity. EVIDENCE ACQUISITION Peer-reviewed studies of behavioral childhood obesity treatments published between 1980 and 2008 were identified from (1) electronic searches of social science and medical databases; (2) research reviews of childhood obesity interventions; and (3) reference lists cited in these reviews. Included studies reported on a controlled obesity intervention trial, targeted overweight or obese children aged 2-18 years, included a primary or secondary anthropometric outcome, and targeted change in dietary intake or physical activity behaviors. EVIDENCE SYNTHESIS 1071 publications were identified and 77 met selection criteria. Studies were coded on established review criteria for external validity elements. All studies lacked full reporting of generalizability elements. Across criteria, the average reporting was 23.9% (range=0%-100%). Infrequently reported were setting-level selection criteria and representativeness, characteristics regarding intervention staff, implementation of the intervention content, costs, and program sustainability. CONCLUSIONS Enhanced reporting of relevant and pragmatic information in behavioral investigations of childhood obesity interventions is needed to improve the ability to evaluate the applicability of results to practice implementation. Such evidence would improve translation of research to practice, provide additional explanation for variability in intervention outcomes, and provide insights into successful adaptations of interventions to local conditions.

Abstract
Background The best outcomes for treating childhood obesity have come from comprehensive family-based programmes. However there are questions over their generalisability. Objective To examine the acceptability and effectiveness of ‘family-based behavioural treatment’ (FBBT) for childhood obesity in an ethnically and socially diverse sample of families in a UK National Health Service (NHS) setting. Methods In this parallel group, randomised controlled trial, 72 obese children were randomised to FBBT or waiting list control. Primary outcomes were body mass index (BMI) and BMI standard deviation scores (SDS). Secondary outcomes were weight, weight SDS, height, height SDS, waist, waist SDS, fat mass index, fat free mass index, blood pressure, and psychosocial measures. Outcomes were assessed at baseline and post-treatment, with analyses on the 6 month data done on an intent-to-treat (ITT) basis. Follow-up anthropometric data were collected at twelve months for the treatment group. Results ITT analyses included all children with baseline data (n=60). There were significant BMI SDS changes (p<0.01) for the treatment and control groups of −0.11 (0.16) and −0.10 (1.6). The treatment group showed a significant reduction in systolic blood pressure (−0.24 (0.7), p<0.05) and improvements in quality of life and eating attitudes (p<0.05), with no significant changes for the control group. However the between-group treatment effects for BMI, body composition, blood pressure and psychosocial outcomes were not significant. There was no overall change in BMI or BMI SDS from 0-12 months for the treatment group. No adverse effects were reported. Conclusions Both treatment and control groups experienced significant reductions in level of overweight, but with no significant difference between them. There were no significant group differences for any of the secondary outcomes.

Abstract
BACKGROUND With the rising prevalence of childhood obesity over the last several decades, and the call for more family-based intervention research to combat childhood obesity, it is important to examine the extant research on family-based interventions in order to make recommendations and improve future research. OBJECTIVE To conduct a meta-analysis of family-based interventions targeting childhood obesity in the last decade in order to inform the research in the next decade. METHODS A literature review was conducted between December 2009-April 2010. Studies published between the years 2000-2009 that used family-based interventions to treat childhood obesity were included. A total of 20 studies met inclusionary criteria. RESULTS Although results varied by study design, the majority of studies had a moderate to large effect size for change in the target child's BMI (BMI percentile, zBMI, percent overweight) after participating in a family-based intervention. Long-term change varied by study, but the majority of studies produced sustainable change in child BMI, although smaller effect sizes. Change in secondary variables (dietary intake, sugar-sweetened beverage intake, physical activity) were substantially different between studies and are reported as trends. CONCLUSION To date, there is preliminary evidence suggesting that family-based interventions targeting childhood obesity are successful in producing weight loss in the short and long-term. Including families in weight loss treatment of obese children warrants further implementation and study. Limitations with the research, recommendations for future research, and implications for practitioners working with overweight/obese children are discussed.

Abstract
This review aims to assess the effectiveness of psychological interventions for treating childhood obesity. Firm conclusions about the effectiveness of psychological interventions to treat childhood obesity remain unclear. Based on current knowledge, the review suggests that a number of interventions may be effective including: multi-component family-based behavioural interventions, interventions aimed at reducing sedentary behaviour and/or increasing physical activity levels as a component of family-based behavioural treatments, in addition to population-based school-wide treatment for girls. Further investment is needed to improve current research and find new, more imaginative ways to research childhood obesity.

Abstract
Physical activity (PA) and diet directly influence obesity and metabolic syndrome (MS) as important determinants of body composition. Understanding how PA relates to MS in youth is of great importance, and could offer a common strategy for clinical and public health approaches to control this condition. The underlying disorder of MS is a condition of insulin resistance, and a strong relationship between PA level and insulin sensitivity is clearly ascertained. The type, duration, frequency and intensity of PA affect fuel metabolism, in particular carbohydrate and lipid oxidation. The possible modulation of metabolism because of increased fat oxidation by PA is the basis for both prevention and restoration of insulin resistance and MS in obese children. In daily clinical practice, diet followed by pharmacologic treatment are usually the approaches taken, whereas PA is often considered just a suggestion. Although diet and PA have different effects on body composition, with both contributing to fat loss, only PA increases muscle mass and thus has a direct effect on metabolic function, expressed by changes in cardiovascular risk factors. Therefore, it is important to remember their complementary but different targets in daily clinical practice, such as body weight control for diet and metabolic health for PA. In this review, we have summarized the literature on the relationship between PA and MS in pediatrics. Then, we have analyzed the possibility of using PA for MS treatment, as an alternative to drugs, by discussing the results of intervention studies, reasons for low compliance to PA, related benefits, adherence difficulties and costs. Finally, we have tried to suggest recommendations for a multiple-step PA strategy in children and adolescents at risk for MS, by considering PA as the 'key' player in treatment.

Abstract
BACKGROUND Obesity is increasing worldwide, reaching alarming proportions. Eating habits have changed over time and nowadays children and adolescents' environment favours the adoption of unhealthy eating behaviours leading to metabolic impairment. OBJECTIVE To explore the impact of eating risk factors and their cumulative effect on anthropometric characteristics in French primary school children. METHODS A total of 278 healthy French children (7.50 ± 0.67 years old) and their legal representatives agreed to take part in this study. Parents were asked to fill in an eating habits clinical questionnaire with questions about skipping breakfast, snacking between meals, eating in front of the TV and sugar-sweetened beverage consumption. On the basis of the answers, children were classified into four categories as a function of the number of eating risk factors they presented. Body mass index (BMI), the sum of four skinfolds (Σ4 skinfolds: tricipital, bicipital, sub-scapular and supra-iliac) and waist circumference (WC) were measured. BMI was transformed into z-BMI for each child. RESULTS ANOVA and unpaired t-test provided significantly higher z-BMI, Σ4 skinfolds and WC in children who were used to skipping breakfast, snacking, watching TV while eating and consuming sugar-sweetened beverages. The more children accumulated eating risk factors, the higher were their z-BMI, Σ4 skinfolds and WC (MANOVA: P < 0.001). CONCLUSIONS Eating habits appear to be associated with anthropometric characteristics in French primary school children. Anthropometric values (z-BMI, Σ4 skinfolds and WC) increased with the number of eating risk factors they presented.

Abstract
Background Because parental recognition of overweight in young children is poor, we need to determine how best to inform parents that their child is overweight in a way that enhances their acceptance and supports motivation for positive change. This study will assess 1) whether weight feedback delivered using motivational interviewing increases parental acceptance of their child's weight status and enhances motivation for behaviour change, and 2) whether a family-based individualised lifestyle intervention, delivered primarily by a MInT mentor with limited support from "expert" consultants in psychology, nutrition and physical activity, can improve weight outcomes after 12 and 24 months in young overweight children, compared with usual care. Methods/Design 1500 children aged 4-8 years will be screened for overweight (height, weight, waist, blood pressure, body composition). Parents will complete questionnaires on feeding practices, physical activity, diet, parenting, motivation for healthy lifestyles, and demographics. Parents of children classified as overweight (BMI ≥ CDC 85th) will receive feedback about the results using Motivational interviewing or Usual care. Parental responses to feedback will be assessed two weeks later and participants will be invited into the intervention. Additional baseline measurements (accelerometry, diet, quality of life, child behaviour) will be collected and families will be randomised to Tailored package or Usual care. Parents in the Usual care condition will meet once with an advisor who will offer general advice regarding healthy eating and activity. Parents in the Tailored package condition will attend a single session with an "expert team" (MInT mentor, dietitian, physical activity advisor, clinical psychologist) to identify current challenges for the family, develop tailored goals for change, and plan behavioural strategies that best suit each family. The mentor will continue to provide support to the family via telephone and in-person consultations, decreasing in frequency over the two-year intervention. Outcome measures will be obtained at baseline, 12 and 24 months. Discussion This trial offers a unique opportunity to identify effective ways of providing feedback to parents about their child's weight status and to assess the efficacy of a supportive, individualised early intervention to improve weight outcomes in young children.

Abstract
There is a dearth of research on the long-term efficacy and safety of treatments for adolescent obesity. This narrative review examined several approaches to treatment, focusing on long-term effectiveness data in adolescents, as well as relevant findings from studies of adults. The available research suggests that lifestyle modification has promise in obese adolescents, although it is not clear that any particular dietary or physical activity approach is more effective than another. Meal replacements are quite effective in adults and deserve further research in adolescents. Extending the length of treatment to teach weight loss maintenance skills is likely to improve long-term outcomes in adolescents, and delivering treatment via the Internet or telephone is a novel way of doing so. Treatment that combines lifestyle modification with the medication orlistat generally appears to be safe but only marginally superior to lifestyle modification alone. More research is needed on the management of adolescent obesity, which has been overlooked when compared with research on the treatment of obesity in children and adults.

Abstract
This study aimed to examine the relational meaning of food, based on the results of a qualitative study of eight obese children (six male and two female) and their families in a Chinese society in Hong Kong. The children range in age from 7 to 13. Findings reveal the important bonding function of food in family relationships. Two clinical themes were identified from the data: (1) food bonding nurturer and obese child; (2) eating and the bonding relationship with extended family. Putting a child on a diet was found to disrupt the bonding between the nurturers and the obese child. Power struggles over the loyalty of the child in food provision were also observed. Implications for practice are discussed.
