Effectiveness of lifestyle interventions in child obesity: systematic review with meta-analysis

The Prevention of Childhood Obesity Is a Priority: The Preliminary Results of the "EpPOI: Education to Prevent Childhood Obesity" Project

BACKGROUND

The increase in childhood obesity rates represents a serious public health problem. The project "EpPOI: Education to prevent childhood obesity" is aimed at a multidisciplinary approach to raise awareness of the importance of preventing childhood obesity through lifestyle education.

METHODS

Two actions by experts were performed: an intervention with children in schools and a meeting for both parents and school staff. Participants completed a questionnaire structured as a Likert scale.

RESULTS

The sample size was 96 people, and awareness of the childhood obesity problem as well as the need for obesity prevention was high among respondents. We also found great interest among participants in having more information on pediatric nutrition and physical activity, with a positive correlation with age. Furthermore, the multivariate regression model configured interest in having more information on nutrition and physical activity as an independent and statistically significant predictor of awareness of childhood obesity as a current issue.

CONCLUSIONS

The results highlight the need to act on childhood obesity through lifestyle prevention strategies early in life.

Effectiveness and cost-effectiveness of a 1-year dietary and physical activity intervention of childhood obesity-study protocol for a randomized controlled clinical trial

BACKGROUND

We investigate and try to find out the optimal duration and intensity for the treatment and content useful for clinical work. The aim of our study is to evaluate the effects of lifestyle intervention on the management of childhood overweight and to explore the factors that contribute to the outcome, as well as the costs for the health care system. The hypotheses of the study are that lifestyle intervention is efficient in reducing BMI-SDS and thus effective in preventing overweight from progressing to obesity, and it is also cost-effective.

METHODS AND ANALYSES

We aim to recruit 80 children and they randomize either to an intervention group or a control group with standard care. The intervention group receives intensive, family-based diet, and physical activity counseling, delivered by a multidisciplinary team of a pediatrician, a nurse, and a clinical nutritionist. The control group does not receive any lifestyle intervention during the study. The inclusion criteria are age of 6-12 years, weight-for-height ≥  + 40% or ≥  + 30%, and increasing curve. All participants fill out the study questionnaires and plasma samples are taken at baseline and at 12 months. Outcome variables will be compared between intervention and control groups.

DISCUSSION

If the effects of this lifestyle intervention are positive and it is also cost-effective, the implication of our study will be of great importance to the treatment of childhood obesity and to improve the health care system.

Parent Intention to Participate in an Online Intervention to Enhance Health Behavior Change Among Youth Treated with Psychotropic Medication Who are Overweight or Obese: An Application of the Theory of Planned Behavior

Youth with mental health disorders (MHD), particularly those who take psychotropic medications, are at increased risk of being overweight or obese (OW/OB) when compared to typical youth. Parents are important resources for interventions addressing OW/OB. However, parents of youth with MHD may face challenges that require interventions designed to address their needs. Prior to investing research funding in the development of interventions for this group, research is needed to understand factors associated with parents' decisions to enroll in these programs. The theory of planned behavior (TPB) provided a framework for examining parents' salient beliefs, direct attitudes, and intention to enroll in a hypothetical online healthy lifestyle intervention for their youth (ages 11-17) with OW/OB and treated with psychotropic medication. Parents who were enrolled in the study (n = 84) completed demographic questionnaires and a TPB questionnaire which was constructed for this study. A confirmatory factor analysis (CFA) of the direct attitude (i.e., attitude toward the behavior, subjective norm, perceived behavioral control) questions generally supported the three-factor model (i.e., RMSEA = .07, 90% CI .03-.11, p = .18; CFI = .96, SRMR = .06). Results from a multiple regression analysis demonstrated that direct attitudes predicted parent intention to participate in an online healthy lifestyle intervention for this sample of youth accounting for 84% of variance. In this preliminary study, the TPB appears to be a promising framework for understanding direct attitudes associated with parent intentions toward intervention participation in this population of youth. Interventions for parents of youth with OW/OB who are prescribed psychotropic medication should consider addressing these direct attitudes to improve intention.

Associations between marital status and weight loss trajectories entering into early adulthood: a Teen-LABS study

BACKGROUND

Among adolescents who underwent metabolic and bariatric surgery (MBS), it is unclear how relationships and specifically marital status (MS) may be associated with long-term weight loss.

OBJECTIVE

In this analysis, we tested for associations between the MS of adolescents who underwent MBS and the MS of their primary caregiver and weight loss trajectory over 8 years.

SETTING

Teen-LABS participating sites.

METHODS

This sample included 231 participants (75.3% female, 71.4% White, 68.0% Roux-en-Y gastric bypass, 27.7% vertical sleeve gastrectomy, 4.3% laparoscopic adjustable gastric band). A linear mixed model was conducted with the dependent variable percent body mass index (BMI) change from preoperatively through 8 years with between-participant factors (1) participant MS, (2) caregiver MS, and (3) interaction between caregiver and participant MS.

RESULTS

One third of participants and 87% of caregivers were ever married (EM). Compared with never-married (NM) participants and caregivers (-14.6%), EM participants and caregivers (-20.6%), EM participants and NM caregivers (-25.9%), and NM participants and EM caregivers (-19.8%), each had significantly greater BMI loss at 8 years (each P < .05). No other group comparisons achieved statistical significance.

CONCLUSIONS

NM participants with NM caregivers had less favorable long-term BMI. Additional research is needed to better understand how relationships affect behavior change and weight loss after MBS.

Exploring caregivers' attitudes and beliefs about nutrition and weight management for young people with Duchenne muscular dystrophy

INTRODUCTION/AIMS

Obesity disproportionately affects children and adolescents with Duchenne muscular dystrophy (DMD) and with adverse consequences for disease progression. This study aims to: explore barriers, enablers, attitudes, and beliefs about nutrition and weight management; and to obtain caregiver preferences for the design of a weight management program for DMD.

METHODS

We surveyed caregivers of young people with DMD from four Australian pediatric neuromuscular clinics. Survey questions were informed by the Theoretical Domains Framework and purposefully designed to explore barriers and enablers to food and weight management. Caregivers were asked to identify their preferred features in a weight management program for families living with DMD.

RESULTS

Fifty-three caregivers completed the survey. Almost half (48%) perceived their son as above healthy weight. Consequences for those children were perceived to be self-consciousness (71%), a negative impact on self-esteem (64%) and movement (57%). Preventing weight gain was a common reason for providing healthy food and healthy eating was a high priority for families. Barriers to that intention included: time constraints, selective food preferences, and insufficient nutrition information. Caregivers preferred an intensive six-week weight management program addressing appetite management and screen time.

DISCUSSION

Managing weight is an important issue for caregivers of sons with DMD; yet several barriers exist. Individualized 6 week programs are preferred by caregivers to improve weight management for DMD.

Parental Perceptions of Physical Activity and Risk of Disease Associated with Sedentary Behaviours in Infants and Toddlers

OBJECTIVES

The current study intends to measure parents' perceptions of newborn and toddler physical activity.

METHODS

A Cross-sectional study was conducted at the pediatric clinic at a University Hospital in Riyadh. The parents or guardians of children 0 to 3 years of age, healthy infants, and toddlers who visited the vaccination and pediatric clinic at a University Hospital in Riyadh, were recruited. The Parental Perceptions of Physical Activity Scale (PPPAS) was translated into the Arabic language. The Chi-square test was applied to observe the association between categorical variables. P value < 0.05 was considered to be statistically significant.

RESULTS

A total of 383 parents were recruited. There was a significant association observed between physical activity and income, employment, and education. A significant association was observed between the following perceptions; the child enjoys physical activity, it increases the child's fitness level, the strength of the muscles, flexibility, and life span, improves happiness, keeps the child active, and provides a sense of achievement, and decrease future weight problems.

CONCLUSION FOR PRACTICE

The study determined that parental inclination towards engaging in a physical activity intervention for their infants, as well as identifying any concerns that may impact their children's adherence to physical activity was satisfied.

Obesity in Children and Adolescents: 2022 Update of Clinical Practice Guidelines for Obesity by the Korean Society for the Study of Obesity

The prevalence of obesity in children and adolescents has been gradually increasing in recent years and has become a major health problem. Childhood obesity can readily progress to adult obesity. It is associated with obesity-related comorbidities, such as type 2 diabetes mellitus, hypertension, obstructive sleep apnea, non-alcoholic fatty liver disease, and the risk factor for cardiovascular disease. It is important to make an accurate assessment of overweight and obesity in children and adolescents with consideration of growth and development. Childhood obesity can then be prevented and treated using an appropriate treatment goal and safe and effective treatment strategies. This article summarizes the clinical practice guidelines for obesity in children and adolescents that are included in the 8th edition of the Clinical Practice Guidelines for Obesity of the Korean Society for the Study of Obesity.

Barriers and Facilitators of Implementing a Healthy Lifestyle Intervention at Workplaces in South Africa

Current evidence indicates that workplace health and wellness programmes provide numerous benefits concerning altering cardiovascular risk factor profiles. Implementing health programmes at workplaces provide an opportunity to engage adults towards positive and sustainable lifestyle choices. The first step in designing lifestyle interventions for the workplace is understanding the barriers and facilitators to implementing interventions in these settings. The barriers and facilitators to implementing lifestyle interventions in the workplace environment was qualitatively explored at two multinational consumer goods companies among seven workplaces in South Africa. Semi-structured in-depth interviews (IDIs) were conducted with ten workplace managers. Five focus group discussions (FGDs) were conducted among workplace employees. The IDI findings revealed that the main facilitators for participation in a lifestyle intervention programme were incentives and rewards, educational tools, workplace support, and engaging lessons. In contrast, the main facilitator of the FGDs was health and longevity. The main barriers from the IDIs included scheduling time for lifestyle interventions within production schedules at manufacturing sites, whereas time limitations, a lack of willpower and self-discipline were the main barriers identified from the FGDs. The findings of this study add to literature on the barriers and facilitators of implementing healthy lifestyle interventions at workplaces and suggest that there is a potential for successfully implementing intervention programmes to improve health outcomes, provided that such efforts are informed and guided through the engagement of workplace stakeholders, an assessment of the physical and food environment, and the availability of workplace resources.

Change in Weight Status Among Children Who Do and Do Not Participate in Intensive Health Behavior and Lifestyle Treatment for Obesity

Background: Primary care providers (PCPs) are expected to provide weight management counseling despite having low confidence in their ability to be effective. This analysis examined change in weight status between children who received usual care from their PCP and those who received one of two structured weight management programs in a randomized control trial. Methods: Data from parent-child dyads who were referred to the Guided Self-Help Obesity Treatment in the Doctor's Office study, but did not participate, were examined to determine change in weight status compared with those who participated in the trial. Families were divided into four groups: Group 1, structured treatment with high attendance; Group 2, structured treatment with low attendance; Group 3, PCP/usual care with some weight management counseling; and Group 4, PCP/usual care with no counseling. Anthropometric data and PCP delivery of weight management counseling were abstracted from the electronic health record. Main outcomes were changes in child BMI z-scores, BMI as a percentage relative to the 95th percentile, and BMI as a difference relative to the 95th percentile at the end of treatment and 6-month follow-up for each group. Results: Groups 1 and 2 showed significant decreases in weight status over time, with Group 1 showing the greatest decrease. Groups 3 and 4 remained relatively stable. Changes in weight status in Groups 2, 3, and 4 were significantly different from Group 1 at post-treatment. Conclusions: While structured weight management programs have a significant impact on weight status, those who received some counseling by their PCP did not show significant increases in weight status and were relatively weight stable. Efforts should be broadened to support PCPs as they provide weight management counseling in the office.

Regulation of myogenesis and adipogenesis by the electromagnetic perceptive gene

Obesity has been increasing in many regions of the world, including Europe, USA, and Korea. To manage obesity, we should consider it as a disease and apply therapeutic methods for its treatment. Molecular and therapeutic approaches for obesity management involve regulating biomolecules such as DNA, RNA, and protein in adipose-derived stem cells to prevent to be fat cells. Multiple factors are believed to play a role in fat differentiation, with one of the most effective factor is Ca2+. We recently reported that the electromagnetic perceptive gene (EPG) regulated intracellular Ca2+ levels under various electromagnetic fields. This study aimed to investigate whether EPG could serve as a therapeutic method against obesity. We confirmed that EPG serves as a modulator of Ca2+ levels in primary adipose cells, thereby regulating several genes such as CasR, PPARγ, GLU4, GAPDH during the adipogenesis. In addition, this study also identified EPG-mediated regulation of myogenesis that myocyte transcription factors (CasR, MyoG, MyoD, Myomaker) were changed in C2C12 cells and satellite cells. In vivo experiments carried out in this study confirmed that total weight/ fat/fat accumulation were decreased and lean mass was increased by EPG with magnetic field depending on age of mice. The EPG could serve as a potent therapeutic agent against obesity.

Interdisciplinary Therapy Improves the Mediators of Inflammation and Cardiovascular Risk in Adolescents with Obesity

Obesity is associated with inflammation and an increased risk of cardiovascular disease and premature mortality, as well as a range of other conditions. Obesity is a growing global problem, not only in adults, but also in children and adolescents. Therefore, the present study aimed to assess the effects of a one-year interdisciplinary intervention on the cardiometabolic and inflammatory profiles of adolescents with obesity. Twenty-two adolescents completed the intervention, which included clinical, nutritional, psychological and physical exercise counselling. Body composition, and metabolic, inflammatory, and cardiovascular risk biomarkers were analyzed before and after one year of intervention. Visceral and subcutaneous fat were determined ultrasonographically. The homeostasis model assessment of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI) equation were used to estimate insulin resistance and insulin sensitivity, respectively. A reduction in body mass, adiposity, glucose, and insulin and an improved lipid profile were observed after the therapy. Hyperleptinemia was reduced from 77.3% to 36.4%. Plasminogen activator inhibitor-1 (PAI-1), intercellular adhesion molecule 1 (ICAM-1), leptin, the leptin/adiponectin ratio, and the adiponectin/leptin ratio were also significantly improved. Metabolic changes were associated with a reduction in visceral fat and waist circumference, and adiponectin and the leptin/adiponectin ratio were associated with HOMA-IR. The interdisciplinary therapy promoted improvements in hyperleptinemia and metabolic, inflammatory, and cardiovascular biomarkers.

Low-Carbohydrate Diets in Children and Adolescents With or at Risk for Diabetes

Carbohydrate restriction is increasingly popular as a weight loss strategy and for achieving better glycemic control in people with diabetes, including type 1 and type 2 diabetes. However, evidence to support low-carbohydrate diets in youth (children and adolescents 2-18 years of age) with obesity or diabetes is limited. There are no guidelines for restricting dietary carbohydrate consumption to reduce risk for diabetes or improve diabetes outcomes in youth. Thus, there is a need to provide practical recommendations for pediatricians regarding the use of low-carbohydrate diets in patients who elect to follow these diets, including those with type 1 diabetes and for patients with obesity, prediabetes, and type 2 diabetes. This clinical report will: Provide background on current dietary patterns in youth, describe how moderate-, low-, and very low-carbohydrate diets differ, and review safety concerns associated with the use of these dietary patternsReview the physiologic rationale for carbohydrate reduction in youth with type 1 diabetes and for youth with obesity, prediabetes, and type 2 diabetesReview the evidence for low-carbohydrate diets in the management of youth with type 1 diabetesReview the evidence for low-carbohydrate diets in the management of youth with obesity, prediabetes, and type 2 diabetesProvide practical information for pediatricians counseling families and youth on carbohydrate recommendations for type 1 diabetes and for obesity, prediabetes, and type 2 diabetes.

Evidence Base Update on Behavioral Treatments for Overweight and Obesity in Children and Adolescents

OBJECTIVE

This review provides an update to a previous Evidence Base Update addressing behavioral treatments for overweight and obesity in children and adolescents.

METHOD

Articles were identified through a systematic search of the biomedical literature in PubMed/MEDLINE (1946-), Elsevier EMBASE (1947-), SCOPUS (1823-), Clarivate Web of Science Core Collection (WOS, 1900-), PsycINFO (1800-), The Cochrane Library and Clinicaltrials.gov published between June 2014 and August 2022.

RESULTS

Family-based treatment (FBT) remains a well-established treatment for overweight and obesity in children and is now well-established in adolescents and toddlers. Parent-only behavioral treatment remains well-established in children and is now well-established among adolescents and children. Possibly effective treatments continue to include FBT-parent only for adolescents, and behavioral weight loss (BWL) with a family component for adolescents, children, and toddlers. Several variations of FBT and BWL can now be considered possibly effective including FBT+motivational interviewing, FBT+social facilitation maintenance, group-based FBT, low-dose FBT, BWL+stress management, and camp-based BWL. Cognitive behavioral treatment (CBT) for adolescents also met criteria for possibly effective treatments. Current research has also established that behavioral treatments can be effectively delivered in alternative settings (e.g. primary care) and through alternative mediums (e.g. telehealth).

CONCLUSIONS

Research continues to support the use of multicomponent lifestyle interventions in accordance with recent recommendations from the American Academy of Pediatrics, the American Psychological Association, and the United State Preventative Services Task Force. However, more work is needed to ensure appropriate access for children with comorbid medical and psychiatric disorders and children from socially, politically, and economically marginalized groups.

A multicomponent family intervention, combined with salt reduction for children with obesity: a factorial randomized study protocol

BACKGROUND

Clinical trials to treat childhood obesity show modest results, weight regain and high dropout rates. Children with obesity often live in families with habits that contribute to unhealthy weight gain. This study will test whether a family intervention with a Brazilian-adapted Planetary Healthy Diet (PHD) and reduced portion sizes, along with increased physical activity and reduced sedentary behavior, can reduce excessive weight gain. The protocol promotes the intake of in natura products and water and reduces ultra-processed foods, sugar, and sodium. It encourages family lifestyle changes and physical activities, with randomized allocation to experimental and control groups. The responsible family member will be evaluated during follow-up. The control group will receive a print of the Brazilian dietary guideline.

METHODS

A factorial crossover design will also allocate families to receive reduced sodium salt plus anti-inflammatory herbs and a placebo salt. Both the control and intervention groups will be randomly assigned to the sequence of both salts. The approach aims to reduce body weight expectations and evaluate salt's impact on blood pressure. It includes a 1-month intervention, 1-month washout, and 1-month intervention with monthly clinic visits and teleservice by health professionals. The primary outcomes will be the variation in the Body Mass Index (BMI) of the children. BMI and the variation in the blood pressure of the pair (child/mother or father) as well as waist circumference (WC) and waist-to-height ratio (WHtR) will also be measured.

DISCUSSION

The project will test the effectiveness of the use of the recommendations of the PHD, physical activity and a salt-reduced sodium. The results of the present study will allow the refinement of interventions aimed at the treatment of childhood obesity and may help develop guidelines for the treatment of obesity in Brazilian children.

TRIAL REGISTRATION

The study is registered in the Brazilian Registry of Clinical Trials (RBR-10 mm62vs). Registered 10 February 2023.

Lifestyle and Pharmacological Interventions and Treatment Indications for the Management of Obesity in Children and Adolescents

Obesity is a multifactorial chronic impairment that further decreases quality of life and life expectancy. Worldwide, childhood obesity has become a pandemic health issue causing several comorbidities that frequently present already in childhood, including cardiovascular (hypertension, dyslipidemia), metabolic (Type 2 diabetes mellitus, fatty liver disease, metabolic syndrome), respiratory, gastrointestinal and musculoskeletal disorders. In addition, obese children frequently experience stress and psychosocial symptoms, including mood disorders, anxiety, prejudice and low self-esteem. Given that cardiovascular risk factors and pediatric obesity have the tendency to pertain into adulthood, obesity management, including weight control and physical activity, should start before the late teens and certainly before the first signs of atherosclerosis can be detected. This review aims to concisely present options for childhood obesity management, including lifestyle modification strategies and pharmacological treatment, as well as the respective treatment indications for the general practitioner.

Laparoscopic Sleeve Gastrectomy Versus One Anastomosis Gastric Bypass in Adolescents With Obesity

OBJECTIVE

Large studies comparing outcomes between laparoscopic sleeve gastrectomy (LSG) and one anastomosis gastric bypass (OAGB) are scarce and involve adult populations. The aim of the study was to compare perioperative, early postoperative, and 1-year postoperative outcomes of adolescents with obesity who underwent LSG or OAGB surgery.

METHODS

The medical records of adolescents with obesity who underwent LSG or OAGB at the Tel Aviv Sourasky Medical Center from January 2017 to January 2021 were retrospectively reviewed. Data on their gastrointestinal (GI) symptoms and postoperative quality of life were obtained by a telephone interview.

RESULTS

Included were 75 adolescents (median [interquartile range, IQR] age 17.3 [16-18] years) of whom 22 underwent OAGB and 53 underwent LSG. There were no significant preoperative group differences in age, sex, and body mass index score. A low rate of perioperative (5.7% vs 0) and postoperative complication (15.1% vs 10%) with no statistical differences between LSG and OAGB group, respectively, was noted. At 12 months, the percent excessive weight loss + IQR was 42.40% [30.00, 45.00] and 38.00% [33.550, 44.20] in the LSG and OAGB group, respectively ( P = NS). The results of the Pediatric Quality of Life Inventory Gastrointestinal Symptoms scale revealed significantly less food limitation and heartburn after OAGB compared to LSG (food limitation 71.63 vs 53.85 and heartburn 83.654 vs 61.6, P = 0.03 and P = 0.029, respectively).

CONCLUSIONS

Both surgeries are effective and safe for weight loss in the adolescent population. OAGB was associated with significantly fewer GI symptoms compared to LSG.

The treatment of obesity in children and adolescents: consensus position statement of the Italian society of pediatric endocrinology and diabetology, Italian Society of Pediatrics and Italian Society of Pediatric Surgery

This Position Statement updates the different components of the therapy of obesity (lifestyle intervention, drugs, and surgery) in children and adolescents, previously reported in the consensus position statement on pediatric obesity of the Italian Society of Pediatric Endocrinology and Diabetology and the Italian Society of Pediatrics. Lifestyle intervention is the first step of treatment. In children older than 12 years, pharmacotherapy is the second step, and bariatric surgery is the third one, in selected cases. Novelties are available in the field of the medical treatment of obesity. In particular, new drugs demonstrated their efficacy and safety and have been approved in adolescents. Moreover, several randomized control trials with other drugs are in process and it is likely that some of them will become available in the future. The increase of the portfolio of treatment options for obesity in children and adolescents is promising for a more effective treatment of this disorder.

Randomized control trial of a childhood obesity prevention family-based program: "Abriendo Caminos" and effects on BMI

Background

Hispanic individuals are at increased risk for obesity and other chronic health conditions. This article evaluates the effect of a family-based, childhood obesity primary prevention intervention in a community setting.

Methods

A multi-site, randomized controlled trial community program with assessments at pre (T0), post-program (T1), and 6-months post-program (T2). Participating families were recruited from five sites. Only families of Mexican or Puerto Rican heritage with a least one child between 6 and 18 years were included in the study, without weight restrictions. Families were randomized to the intervention and control arms. Intervention families received six-2 h weekly workshops. Control families received printed generic nutrition and wellness information. Heights and weights were measured at the 3-time points to calculate BMI z-scores, BMI-percentiles, and weight status using age- and sex-specific growth charts, according to the CDC guidelines.

Results

There were no differences in BMI-z scores between children in the intervention (n = 239) and control groups (n = 187) at T0. BMI z-scores decreased in the intervention group (-0.03, 95% CI, -0.066, -0.003, p = 0.032) at T1, but not in the control group at T1. Changes in BMI z-scores were not statistically significant at T2.

Conclusion

The Abriendo Caminos intervention effectively prevented unhealthy weight gain in Hispanic children in the short-term, but not at 6-months post-intervention. Younger children and girls benefited more from the program at 6-months post-intervention. Additional efforts are needed to sustain long-term changes. Culturally-tailored programs can provide families with the knowledge to produce short-term changes and a potential pathway for sustainable changes in implementing healthy behaviors.

Obesity in children and adolescents: Overview of the diagnosis and management

Childhood obesity is one of the biggest public health challenges globally. It is associated with various adverse health consequences throughout life. Prevention and early intervention represent the most reasonable and cost-effective approaches. Considerable progress has been achieved in the management of obesity in children and adolescents; yet, implementation in the real world remains a challenge. This article aimed to present an overview of the diagnosis and management of obesity in children and adolescents.

Effectiveness of Lifestyle Nutrition and Physical Activity Interventions for Childhood Obesity and Associated Comorbidities among Children from Minority Ethnic Groups: A Systematic Review and Meta-Analysis

Lifestyle physical activity (PA) and nutrition are known to be effective interventions in preventing and managing obesity-related comorbidities among adult populations but less so among children and adolescents. We examined the effectiveness of lifestyle interventions in children from minority ethnic populations in Western high-income countries (HICs). Our systematic review included 53 studies, involving 26,045 children from minority ethnic populations who followed lifestyle intervention programmes lasting between 8 weeks and 5 years with the aim of preventing and/or managing childhood obesity and associated comorbidities, including adiposity and cardiometabolic risks. The studies were heterogenous in terms of lifestyle intervention components (nutrition, PA, behavioural counselling) and settings (community vs. schools and after-school settings). Our meta-analysis included 31 eligible studies and showed no significant effects of lifestyle interventions when they focused on body mass index (BMI) outcomes (pooled BMI mean change = -0.09 (95% CI = -0.19, 0.01); p = 0.09). This was irrespective of the intervention programme duration (<6 months vs. ≥6 months), type (PA vs. nutrition/combined intervention) and weight status (overweight or obese vs. normal weight) as all showed nonsignificant effects in the sensitivity analysis. Nonetheless, 19 of the 53 studies reported reductions in BMI, BMI z-score and body fat percentage. However, the majority of lifestyle interventions adopting a quasi-design with combined primary and secondary obesity measures (11 out of 15 studies) were effective in reducing the obesity comorbidities of cardiometabolic risks, including metabolic syndrome, insulin sensitivity and blood pressure, in overweight and obese children. Preventing childhood obesity in high-risk ethnic minority groups is best achieved using combined PA and nutrition intervention approaches, which jointly target preventing obesity and its comorbidities, especially the outcomes of diabetes, hypertension and cardiovascular disease. Therefore, public health stakeholders should integrate cultural and lifestyle factors and contextualise obesity prevention strategies among minority ethnic groups in Western HICs.

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.

Adolescent obesity incurs adult skeletal deficits in murine induced obesity model

Adolescent obesity has risen dramatically in the last few decades. While adult obesity may be osteoprotective, the effects of obesity during adolescence, which is a period of massive bone accrual, are not clear. We used a murine model of induced adolescent obesity to examine the structural, mechanical, and compositional differences between obese and healthy weight bone in 16-week-old female C57Bl6 mice. We also examined the effects of a return to normal weight after skeletal maturity (24 weeks old). We found obese adolescent bone exhibited decreased trabecular bone volume, increased cortical diameter, increased ultimate stress, and increased brittleness (decreased plastic energy to fracture), similar to an aging phenotype. The trabecular bone deficits remained after return to normal weight after skeletal maturity. However, after returning to normal diet, there was no difference in ultimate stress nor plastic energy to fracture between groups as the normal diet group increased ultimate stress and brittleness. Interestingly, compositional changes appeared in the former high-fat diet mice after skeletal maturity with a lower mineral to matrix ratio compared to normal diet mice. In addition there was a trend toward increased fluorescent advanced glycation endproducts in the former high-fat diet mice compared to normal diet mice but this did not reach significance (p < 0.05) due to the large variability. The skeletal consequences of adolescent obesity may have lasting implications for the adult skeleton even after return to normal weight. Given the rates of adolescent obesity, skeletal health should be a concern.

Effects of exercise combined with diet intervention on body composition and serum biochemical markers in adolescents with obesity: a systematic review and meta-analysis

BACKGROUND

This systematic review aims to evaluate the effects of exercise combined with diet (ECWD), exercise alone, diet alone, and no intervention on body composition and serum biochemical markers in adolescents with obesity to provide reference for solving the metabolic disorders of adolescents caused by obesity.

CONTENTS

Studies published before January 5, 2021 were retrieved from PubMed, Web of Science, Ovid, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang data, VIP database, and SinoMed. Randomized controlled trials with an age between 10 and 20 years, body mass index (BMI) ≥28 kg/m² or ≥95th percentiles, no history of endocrine and metabolic diseases, heart disease, hematologic disease, and so on before the trial were included.

SUMMARY

Fifteen of the 50,155 studies met the criteria. Meta-analysis showed that ECWD was more effective in reducing BMI (kg/m²) (-2.45 kg/m², 95% CI: -3.06; -1.85) and fat thickness of back (-13.77 mm, 95% CI: -15.92; -11.62), abdomen (-11.56 mm, 95% CI: -14.04; -9.09), and upper arm (-14.81 mm, 95% CI: -16.74; -12.89) than other interventions; in reducing body fat (-7.03 kg, 95% CI: -9.77; -4.29) and thigh circumference (-4.05 cm, 95% CI: -5.58; -2.52), ECWD and diet alone were more effective than exercise alone; ECWD and exercise alone were more effective in reducing waist circumference (-6.05 cm, 95% CI: -8.37; -3.72), waist-to-hip ratio (WHR; -0.06, 95% CI: -0.11; -0.01), upper arm circumference (-2.57 cm, 95% CI: -3.70; -1.45), triglycerides (TG; -0.30 mmol/L, 95% CI: -0.45; -0.14), total cholesterol (TC; -0.30 mmol/L, 95% CI: -0.59; -0.01), and low density lipoprotein (LDL; -0.22 mmol/L, 95% CI: -0.40; -0.04) than diet alone. ECWD also had effects on tumor necrosis factor-α (TNF-α), interleukin-6, leptin, and so on.

OUTLOOK

ECWD is more effective than exercise alone, diet alone, or no intervention in solving the problems of body shape and metabolic disorder of adolescents with obesity.

The Effect of Healthy Lifestyle Strategies on the Management of Insulin Resistance in Children and Adolescents with Obesity: A Narrative Review

Childhood obesity is characterized by an increased risk of several metabolic derangements including insulin resistance (IR). The strongest recommendations to prevent obesity and related complications are a balanced and adequate diet and practicing physical activity from early childhood. In this review, we propose to present the effects of healthy lifestyle strategies, including physical exercise and dietary approaches, on the management of IR and related metabolic derangements. All types of exercise (aerobic, resistance and combined training) effectively reduce IR in pediatric patients with obesity; it seems that aerobic and combined training stimulate greater improvements in IR compared to resistance training. Balanced normocaloric or hypocaloric dietary approaches are also valid strategies to address IR; it is not possible to assess the long-term impact of varying macronutrients on cardiometabolic risk. The glycemic index/load evaluation is a useful dietary approach to glucose metabolism control. Similarly, they should adopt the principle of the Mediterranean diet. Randomized studies with longer monitoring are needed to define the benefits of nutritional supplementation on IR. Considering that healthy style acquisition could track to later ages, programs of healthy lifestyle starting with children offer a better preventive strategy to preserve metabolic control and children's health.

A Multidisciplinary Approach to Pediatric Obesity Shows Improvement Postintervention

OBJECTIVE

Outpatient management of pediatric obesity can be difficult, requiring a significant time commitment from both provider and patient. Multidisciplinary clinic-based programs have shown promising effects in reducing BMI during intervention, but whether these changes are sustained over time is not well studied. The purpose of this study was to determine the post-treatment outcomes of children seen in a multidisciplinary pediatric obesity clinic (MPOC).

METHODS

A retrospective chart review was performed using the MPOC database, which included all clinic patients from January 2008 to August 2016 who attended a minimum of 2 visits (n = 472). The primary outcome was the absolute change in BMI Z-score (BMIZ) from the final intervention visit compared to 1- and 2-years post-intervention. Multivariate regression analysis was performed to characterize predictors of change in BMIZ.

RESULTS

MPOC patients ranged in age from 3 to 18 years. Mean BMIZ decreased significantly during intervention (-0.13 ± 1.47, P < .001) and was maintained at 1- and 2-years post-intervention. In participants ages 3 to 5, BMIZ further decreased at 1 year post intervention (-0.27 ± 0.26, P < .001). Age at time of referral was the only significant predictor of change in BMIZ.

CONCLUSIONS

Outpatient, multidisciplinary intervention for pediatric obesity was effective in reducing or stabilizing BMIZ during and beyond the intervention, particularly when patients were referred at an early age. Although primary prevention is the ideal management, multidisciplinary clinic intervention can be effective in the sustained treatment of pediatric obesity.

Beyond bariatric surgery and weight loss medicaments. A systematic review of the current practice in obesity rehabilitative inpatient programs in adults and pediatrics

Background

Obesity treatment strategies mainly include outpatient lifestyle modification, drugs and bariatric surgery. Voluntary rehabilitative inpatient programs are gaining relevance as potential alternative settings of care that focus on weight loss and prevention of weight regain through a multidisciplinary approach, but their prevalence is still limited due to the high costs.

Aim

Considering the lack of evidence in this area, the objective of this study is to systematically review the currently available literature on non-pharmacological and non-surgical inpatient programs aimed at weight loss, to clarify the efficacy and the characteristics of these interventions.

Methods

Proper English language articles from 2000 to 2022 were searched on relevant databases. Quality assessment was performed by two different authors using ROB2 and robvis tools. Adult and pediatric studies were reviewed separately and their characteristics were systematically displayed.

Results

36 articles were included (20 on adults, 16 on children, and adolescents) for a total of 5,510 individuals. The multidisciplinary approach was mainly comprehensive of a low-calorie diet, scheduled physical activity, and psychological support based on behavioral treatment. Educational and cooking sessions were present at a lower rate. Globally, inpatient weight loss programs showed a consistent efficacy in reducing body weight and inducing beneficial effects on quality of life, psychological well-being, eating behavior, physical performance, and fatigue. Follow-up data were scarce, but with a high percentage of patients regaining weight after a short period.

Conclusion

Weight loss inpatient rehabilitation is a promising area that has evidence of all-rounded success in the amelioration of several aspects related to obesity. Nevertheless, it appears to be quite inconsistent in preserving these benefits after the intervention. This might slow the innovation process in this area and preclude further investments from national healthcare. Personalized and enriched programs could show greater impact when focusing on the behavioral and educational aspects, which are crucial points, in particular in pediatrics, for setting up a long-lasting lifestyle modification. More studies are therefore necessary to evaluate long-term efficacy based on the different work-up models.

Childhood Obesity: Position Statement of Polish Society of Pediatrics, Polish Society for Pediatric Obesity, Polish Society of Pediatric Endocrinology and Diabetes, the College of Family Physicians in Poland and Polish Association for Study on Obesity

Childhood obesity is one of the most important problems of public health. Searching was conducted by using PubMed/MEDLINE, Cochrane Library, Science Direct, MEDLINE, and EBSCO databases, from January 2022 to June 2022, for English language meta-analyses, systematic reviews, randomized clinical trials, and observational studies from all over the world. Five main topics were defined in a consensus join statement of the Polish Society of Pediatrics, Polish Society for Pediatric Obesity, Polish Society of Pediatric Endocrinology and Diabetes and Polish Association for the Study on Obesity: (1) definition, causes, consequences of obesity; (2) treatment of obesity; (3) obesity prevention; (4) the role of primary care in the prevention of obesity; (5) Recommendations for general practitioners, parents, teachers, and regional authorities. The statement outlines the role of diet, physical activity in the prevention and treatment of overweight and obesity, and gives appropriate recommendations for interventions by schools, parents, and primary health care. A multisite approach to weight control in children is recommended, taking into account the age, the severity of obesity, and the presence of obesity-related diseases. Combined interventions consisting of dietary modification, physical activity, behavioral therapy, and education are effective in improving metabolic and anthropometric indices. More actions are needed to strengthen the role of primary care in the effective prevention and treatment of obesity because a comprehensive, multi-component intervention appears to yield the best results.

Factors Associated With Treatment Adherence to a Lifestyle Intervention Program for Children With Obesity: The Experience of a Large Tertiary Care Pediatric Hospital

Early dropout and treatment adherence are main challenges in the treatment of children with obesity. The aim of this study was to identify factors associated with attrition and adherence to weight loss intervention program. We retrospectively reviewed the medical records of all the children who entered the program for pediatric weight loss over 5 years and retrieved demographic and clinical characteristics. Attrition and adherence were documented. Ninety-two of the 248 enrolled children (52% women, mean age 11.1 ± 3.9 years, mean body mass index 31.1 ± 7 kg/m²) dropped out (37%). Dropping out correlated with male sex, low parental education, and self-referral to the clinic (P < .05 for all). Adherence correlated with older age and the mother's healthy lifestyle (P < .05 for all). Sex, parental education, and referral source may predict treatment attrition. Early recognition of children at risk of attrition may help to facilitate better care of those children.

Cardiac cycle: an observational/interventional study protocol to characterise cardiopulmonary function and evaluate a home-based cycling program in children and adolescents born extremely preterm

INTRODUCTION

Extremely preterm (EP)/extremely low birthweight (ELBW) individuals may have an increased risk for adverse cardiovascular outcomes. Compared with term-born controls, these individuals have poorer lung function and reduced exercise capacity. Exercise interventions play an important role in reducing cardiopulmonary risk, however their use in EP/ELBW cohorts is unknown. This study, cardiac cycle, aims to characterise the cardiopulmonary system of children and adolescents who were born EP compared with those born at term, following acute and chronic exercise bouts.

METHODS AND ANALYSIS

The single-centre study comprises a home-based exercise intervention, with physiological characterisation at baseline and after completion of the intervention. Fifty-eight children and adolescents aged 10-18 years who were born EP and/or with ELBW will be recruited. Cardiopulmonary function assessed via measures of blood pressure, arterial stiffness, capillary density, peak oxygen consumption, lung clearance indexes and ventricular structure/function, will be compared with 58 age-matched and sex-matched term-born controls at baseline and post intervention. The intervention will consist of a 10-week stationary cycling programme, utilising Zwift technology.

ETHICS AND DISSEMINATION

The study is approved by the Ethics Committee of the Royal Children's Hospital Melbourne under HREC2019.053. Results will be disseminated via peer-reviewed journal regardless of outcome.

Effect of Diet and Exercise-Induced Weight Loss among Metabolically Healthy and Metabolically Unhealthy Obese Children and Adolescents

Objective: To study the effect of diet- and exercise-based lifestyle intervention on weight loss (WL) and cardiovascular risk among metabolically healthy obese (MHO) and metabolically unhealthy obese (MUO) children and adolescents. Methods: The sample included 282 obese individuals (54% males, age (±SD) 12.9 (±2.3) years) who completed a 3- to 4-week WL camp program between 2017 and 2019. MUO was defined according to the consensus-based definition of pediatric MHO in 2018. Results: The intervention exhibited significantly benefits in improving body weight, body mass index, body fat ratio, waist circumference, systolic blood pressure (SBP), diastolic blood pressure (DBP), resting heart rate (RHR), triglycerides (TG), total cholesterol, and low-density lipoprotein−cholesterol levels in both MHO and MUO groups (for all comparisons, p < 0.01). However, the beneficial high-density lipoprotein−cholesterol (HDL-C) level (both p < 0.01) decreased evidently in both groups after intervention. In addition, percent changes in SBP (p < 0.001), DBP (p < 0.001), RHR (p = 0.025), fasting blood glucose (p = 0.011), and TG (p < 0.001) were more profound in MUO group than that in MHO group. Conclusion: Metabolical health is a mutable and transient state during childhood. Although both groups gained comparable WL benefits from diet- and exercise-based lifestyle intervention, the MUO group may benefit more than the MHO group. Strategies aiming at lowering blood pressure and preventing the decrease of HDL-C level should be considered for the precise treatment of childhood obesity in clinical practice, with the goal of improving metabolically healthy state.

Obesity in children and adolescents: epidemiology, causes, assessment, and management

This Review describes current knowledge on the epidemiology and causes of child and adolescent obesity, considerations for assessment, and current management approaches. Before the COVID-19 pandemic, obesity prevalence in children and adolescents had plateaued in many high-income countries despite levels of severe obesity having increased. However, in low-income and middle-income countries, obesity prevalence had risen. During the pandemic, weight gain among children and adolescents has increased in several jurisdictions. Obesity is associated with cardiometabolic and psychosocial comorbidity as well as premature adult mortality. The development and perpetuation of obesity is largely explained by a bio-socioecological framework, whereby biological predisposition, socioeconomic, and environmental factors interact together to promote deposition and proliferation of adipose tissue. First-line treatment approaches include family-based behavioural obesity interventions addressing diet, physical activity, sedentary behaviours, and sleep quality, underpinned by behaviour change strategies. Evidence for intensive dietary approaches, pharmacotherapy, and metabolic and bariatric surgery as supplemental therapies are emerging; however, access to these therapies is scarce in most jurisdictions. Research is still needed to inform the personalisation of treatment approaches of obesity in children and adolescents and their translation to clinical practice.

Exercise dose-response relationship with heart rate variability in individuals with overweight and obesity: protocol for a systematic review and meta-analysis of randomised controlled trials

INTRODUCTION

Obesity is a chronic relapsing disease process and serious public health concern that can lead to chronic diseases, medical complications and a higher risk of disability. Another significant feature of obesity is dysfunction in cardiac autonomic function, which leads to changes in parasympathetic and sympathetic regulation, which can be measured using heart rate variability (HRV). The objective of this review is to estimate the extent to which exercise doses impacts on HRV among individuals living with overweight and obesity class I and II.

METHODS AND ANALYSIS

A systematic literature search will be performed using PubMed/Medline, Scopus, EMBASE, ProQuest, CINAHL, Web of Science and the Cochrane Library for articles dating from 1965 to December 2021. Inclusion criteria include studies designed as parallel-arm randomised trials, enrolling adolescent and adult individuals with overweight (body mass index, BMI≥25 to ≤29.9) and obesity (class I BMI: 30-34.9 and class II BMI: 35-39.9) undergoing aerobic or resistance training or concurrent exercise training. For data synthesis, sensitivity analysis, subgroup analysis and risk of bias assessment, Stata V.13.0 software will be used.

ETHICS AND DISSEMINATION

Formal ethical approval is not required. This systematic review will be submitted to a peer-reviewed journal.

Calorie Compensation and Self-Regulation of Food Intake in College Students

OBJECTIVE

To examine self-regulation of food intake among college students.

DESIGN

Randomized cross-over study completed between September and November, 2019.

SETTING

A large public university, Florida International University in South Florida.

PARTICIPANTS

A total of 60 undergraduate college students, mean age of 19.8 ± 1.43 years old, 62% female, 74% Hispanic, 76% White.

INTERVENTION(S)

Participants attended 2 trials 1 week apart. During each visit, students were offered a preload drink (either 0 or 210 kcal) followed by a buffet-style lunch. Food intake was estimated using weights and pictures of the plates before and after eating and was compared between the 2 sessions.

MAIN OUTCOME MEASURE(S)

Self-regulation by calculating compensation indices (COMPX) and their correlation with students' body mass index (BMI).

ANALYSIS

Intake differences were examined using Welch and t tests. Regression analysis was used to assess correlations.

RESULTS

Students exhibited the ability to calorie compensate when intake is manipulated with a mean COMPX of 95.57 ± 71.19. No score was perfect. There was a significant correlation between BMI and COMPX scores (F = 10.71, P < 0.001, r² = 0.292). Food choices differed between different BMI categories.

CONCLUSIONS AND IMPLICATIONS

Participants showed some degree of self-regulation, which suggests opportunities for creating effective interventions to improve health status and promote a more sustainable method to control consumption among college students.

Weight outcomes of NU-HOME: a randomized controlled trial to prevent obesity among rural children

BACKGROUND

Rural children are at greater obesity risk than their urban peers. The NU-HOME study is an innovative collaborative effort to prevent childhood obesity in rural communities. Weight outcomes of the NU-HOME study, a family-meal focused randomized controlled trial (RCT) are described. We hypothesized that compared to control group children, intervention group children would have significantly lower weight-related post-intervention (PI) outcomes.

METHODS

Participants were 114 dyads (7-10 year-old rural children and a parent). In 2017-2018 and 2018-2019, research staff measured height, weight and body fat at baseline (BL) and PI. Families were randomized to intervention (n = 58) or control (n = 56) groups without blinding. Designed with Social Cognitive Theory and community engagement, the NU-HOME program included seven monthly sessions delivered in community settings and four goal-setting calls. The program engaged entire families to improve healthy eating, physical activity, family meals and the home food environment. Multiple linear and logistic regression models tested PI outcomes of child BMIz-score, percent body fat, percent over 50th percentile BMI, and overweight/obesity status by treatment group, adjusted for BL values and demographics (n = 102).

RESULTS

No statistically significant intervention effects were seen for child BMIz or overweight/obesity status. However, a promising reduction in boys' percent body fat (- 2.1, 95% CI [- 4.84, 0.63]) was associated with the intervention.

CONCLUSIONS

Although our findings were in the hypothesized direction, making significant impacts on weight-related outcomes remains challenging in community trials. Comprehensive family-focused programming may require intensive multi-pronged interventions to mitigate complex factors associated with excess weight gain.

Impact of Lifestyle Modifications on Alterations in Lipid and Glycemic Profiles and Uric Acid Values in a Pediatric Population

Cardiometabolic risk factors are frequent in children and adolescents with excess weight. The aim of this study was to evaluate the effects of lifestyle modifications on alterations in lipid and glycemic profiles and uric acid values in a pediatric population at increased cardiovascular risk. The study involved 276 subjects with a mean age of 10.6 (2.3) years. Body mass index (BMI) z-score and biochemical parameters (serum low-density lipoprotein (LDL) cholesterol, triglycerides and uric acid and homeostasis model assessment to quantify insulin resistance (HOMA index)) were assessed at baseline and at the end of a median follow-up of 14.7 (12.4, 19.3) months. Throughout follow-up, all children received a non-pharmacological treatment based on increased physical activity, reduced sedentary activity and administration of a personalized, healthy and balanced diet. All children attended periodic quarterly control visits during follow-up. Multivariable statistical analyses showed that each BMI z-score point reduction at follow-up was associated with an 8.9 (95% CI −14.2; −3.6) mg/dL decrease in LDL cholesterol (p = 0.001), 20.4 (95% CI −30.0; −10.7) mg/dL in triglycerides (p < 0.001), 1.6 (95% CI −2.2; −1.0) in HOMA index (p < 0.001), and 0.42 (95% CI −0.66; −0.18) mg/dL in uric acid (p = 0.001) values. At each reduction of the BMI z-score by one point, the odds of presenting with insulin resistance and hyperuricemia at follow-up significantly decreased (OR 0.23, 95% CI 0.10−0.50, and OR 0.32, 95% CI 0.10−0.95, p < 0.001 and p < 0.05, respectively). Improvement of dietary habits and lifestyles may improve lipid and glycemic profiles and serum uric acid values in a pediatric population.

Interventions to Treat Obesity in Mexican Children and Adolescents: Systematic Review and Meta-Analysis

CONTEXT

Prevalence of overweight and obesity has been rising in the past 3 decades among Mexican children and adolescents.

OBJECTIVE

To systematically review experimental studies evaluating interventions to treat obesity in Mexican children and adolescents (≤18 years old).

DATA SOURCES

For this study, 13 databases and 1 search engine were searched.

DATA ANALYSIS

A total of 29 studies met the inclusion criteria. Overall, 2302 participants (age range, 8-16 years) from 11 states in Mexico were included. Most of the studies (n = 17 of 29) were provided in a clinical setting. A random-effect meta-analysis of 4 randomized controlled trials was conducted and a significant effect was found on body mass index reduction that favored the intervention group (-1.52; 95%CI, -2.15 to -0.89) for short-term (≤6 mo) interventions.

CONCLUSIONS

A multicomponent, multidisciplinary, and individualized intervention that includes dietary modifications, physical activity practice, behavioral strategies, and active parental involvement might help treat childhood obesity in Mexico. However, long-term results need to be produced to identify effectiveness pointers that might help establish an integrated, long-lasting care model to treat obesity.

Weight management interventions that include dietary components for young people with chronic health care needs: A systematic review

AIMS

To identify and describe weight management interventions that include a dietary component for young people with chronic healthcare needs and overweight or obesity and their effect on body mass index (BMI) or weight.

METHODS

Six databases were searched in 2017 and 2020 for experimental studies in English: Ovid MEDLINE, Ovid Embase, Ovid AMED, EBSCO CINAHL, Scopus and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. Two independent reviewers conducted data extraction and quality assessment using the Cochrane Risk of Bias tool. Eligible studies included young people with chronic healthcare needs ≤18 years with overweight or obesity with an intervention that included a dietary component. Eligible outcomes were BMI or weight. Data were synthesised narratively.

RESULTS

The search identified 15 293 references, 12 studies were included (randomised controlled trials n = 5, before-after comparisons n = 7). Participant diagnoses were neurodevelopmental disabilities (n = 5) and mental illness (n = 1); survivors of cancers or tumours (n = 4); congenital heart disease (n = 1) and; migraine (n = 1). No studies addressed weight management in physical disabilities. Eight studies demonstrated a significant reduction in BMI or weight. Of these, most interventions used dietary counselling or an energy deficit, were family-focused, multicomponent and delivered by a multidisciplinary team including dietitians. A high risk of bias was detected across studies.

CONCLUSIONS

There is limited high-quality evidence about effective dietary solutions for the management of overweight and obesity for young people with chronic healthcare needs. While more research is required, dietary management appears to be important to manage weight in these populations.

Pediatric quality of life multidimensional fatigue scale (PedsQL-MFS) detects the effects of a 3-week Inpatient body weight reduction program for children and adolescents with obesity

BACKGROUND

Fatigue is a frequent complaint amongst children and adolescents with obesity, and it interferes with adherence to dietary and exercise regimes that could reduce obesity. The present study evaluated the effect of an inpatient 3-week body weight reduction program on body weight and fatigue.

METHOD

One hundred children and adolescents with obesity (64% female; aged 11-18 years) undertook an inpatient program of personalized diet, daily exercise, education, and counselling.

RESULTS

The sample evidenced a mean reduction in body mass (females: ΔM = 4.3 (sd = 2.1) kg, p < .001), males: ΔM = 6.2 (sd = 2.6) kg, p < .001), BMI standard deviation score (females: ΔM = 0.17 (sd = 0.07), males: ΔM = 0.24 (sd = 0.08), p < .001) and fatigue (females: ΔM = 7.8 (sd = 9.7), males: ΔM = 5.0 (sd = 6.9), p < .001) as measured by the Pediatric Quality of Life Multidimensional Fatigue Scale (PedsQL-MFS) and improvements on the Attention problems subscale of the Youth Self Report (total sample: ΔM = 0.89 (sd = 2.44), p < .001). Reliable change analyses revealed fatigue changes were achieved by up to 34% females and 17% males, but the majority did not achieve reliable change and changes in fatigue were not correlated with changes in body mass.

CONCLUSIONS

The program achieved clinically significant improvements in some children and adolescents. Future studies should explore predictors of treatment responsiveness. Trial registration Observational study. Not registered.

Association between Frequency of Toothbrushing and Metabolic Syndrome among Adolescents: A 5-Year Follow-Up Study

This study longitudinally examines the relationship between the frequency of toothbrushing and the development of selected components of metabolic syndrome (MetS), along with the potential role of salivary biomarkers in this relationship. In 2014, 6317 12-year-old children underwent health examinations (T1), of which, 348 children participated in the second stage of data collection in 2019 (T2). The association between the change in the metabolic status during the 5-year follow-up examination (between T1 and T2) and frequency of toothbrushing was assessed using multinomial logistic regression analyses. At T2, healthy adolescents had significantly higher odds of toothbrushing twice or more daily compared with adolescents with components of MetS (OR = 1.99, 95% CI 1.15-3.45). Adolescents who were healthy at T1 but developed components of MetS at T2, had significantly higher frequencies of dining-out compared with adolescents with components of MetS at both T1 and T2 (OR = 0.09, 95% CI 0.02 to 0.49). Adolescents who were 'healthy' at both T1 and T2 had significantly (p < 0.05) lower levels of C-reactive protein (T2), insulin (T1 and T2), interleukin-6 (T1) and adiponectin (T1) compared with adolescents who had components of MetS. Toothbrushing and frequency of dining-out were associated with the presence of MetS components.

Effectiveness of a Multifaceted Intervention for Prevention of Obesity in Primary School Children in China: A Cluster Randomized Clinical Trial

IMPORTANCE

A rapid nutritional transition has caused greater childhood obesity prevalence in many countries, but the repertoire of effective preventive interventions remains limited.

OBJECTIVE

To determine the effectiveness of a novel multifaceted intervention for obesity prevention in primary school children.

DESIGN, SETTING, AND PARTICIPANTS

A cluster randomized clinical trial was conducted during a single school year (from September 11, 2018, to June 30, 2019) across 3 socioeconomically distinct regions in China according to a prespecified trial protocol. Twenty-four schools were randomly allocated (1:1) to the intervention or the control group, with 1392 eligible children aged 8 to 10 years participating. Data from the intent-to-treat population were analyzed from October 1 to December 31, 2019.

INTERVENTIONS

A multifaceted intervention targeted both children (promoting healthy diet and physical activity) and their environment (engaging schools and families to support children's behavioral changes). The intervention was novel in its strengthening of family involvement with the assistance of a smartphone app. The control schools engaged in their usual practices.

MAIN OUTCOMES AND MEASURES

The primary outcome was the change in body mass index (BMI; calculated as weight in kilograms divided by height in square meters) from baseline to the end of the trial. Secondary outcomes included changes in adiposity outcomes (eg, BMI z score, prevalence of obesity), blood pressure, physical activity and dietary behaviors, obesity-related knowledge, and physical fitness. Generalized linear mixed models were used in the analyses.

RESULTS

Among the 1392 participants (mean [SD] age, 9.6 [0.4] years; 717 boys [51.5%]; mean [SD] BMI, 18.6 [3.7]), 1362 (97.8%) with follow-up data were included in the analyses. From baseline to the end of the trial, the mean BMI decreased in the intervention group, whereas it increased in the control group; the mean between-group difference in BMI change was -0.46 (95% CI, -0.67 to -0.25; P < .001), which showed no evidence of difference across different regions, sexes, maternal education levels, and primary caregivers (parents vs nonparents). The prevalence of obesity decreased by 27.0% of the baseline figure (a relative decrease) in the intervention group, compared with 5.6% in the control group. The intervention also improved other adiposity outcomes, dietary, sedentary, and physical activity behaviors, and obesity-related knowledge, but it did not change moderate- to vigorous-intensity physical activity, physical fitness, or blood pressure. No adverse events were observed during the intervention.

CONCLUSIONS AND RELEVANCE

The multifaceted intervention effectively reduced the mean BMI and obesity prevalence in primary school children across socioeconomically distinct regions in China, suggesting its potential for national scaling.

Effects of Exercise in Improving Cardiometabolic Risk Factors in Overweight Children: A Systematic Review and Meta-Analysis

This meta-analysis aims to evaluate the effects of exercise in improving cardiometabolic risk factors in overweight children and adolescents until the adolescent age, which is 18 years. A systemic search was conducted using the electronic databases PubMed/Medline, Cochrane Library, and Google Scholar, from inception to 29 June 2021. All statistical analyses were conducted in Review Manager 5.4.1. All studies meeting the inclusion criteria were selected. A random-effect model was used to pool the studies, and the results are reported in the odds ratio (OR) and corresponding 95% Confidence interval (CI). Twelve randomized control trials were selected for meta-analysis. Significant results were obtained for BMI in children after the interventions (0.38 95% CI 0.14, 0.62; p = 0.002; I2 = 65%). LDL level was also found significantly reduced (0.41 95% CI 0.01, 0.82; p = 0.05; I2 = 83%). Other factors such as HDL level, blood pressure, blood glucose level, body weight, and waist circumference were also analyzed. We found that exercise interventions significantly improved several cardiometabolic risk factors such as BMI, LDL level, BP, and blood glucose level. However, no significant effect on HDL concentration, waist circumference, and body weight were found. Long-term interventions are needed to attain improvement in all cardiometabolic risk factors.

Promoting healthy lifestyle behaviours in youth: Findings from a novel intervention for children at risk of cardiovascular disease

Objectives

Obesity is the most prevalent risk factor for cardiovascular disease (CVD) in children. We developed a 2-year lifestyle intervention for youth at risk of CVD. We assessed changes in body mass index z-scores (zBMI) and key cardiometabolic risk factors, physical fitness, and capacity among those who completed the program.

Methods

The CIRCUIT program is a multidisciplinary lifestyle intervention for children aged 4 to 18 years at risk of CVD, based on a personalized plan to improve cardiometabolic outcomes by increasing physical activity and reducing sedentary behaviours. Both at baseline and 2-year follow-up, we measured zBMI, blood pressure z-scores (zBP), adiposity (%body and %trunk fat), fasting blood glucose and lipid profile, aerobic (VO2max) and anaerobic (5×5 m shuttle run test) fitness, and physical capacity indicators. Differences between baseline and follow-up were examined using paired t-tests (for age-sex standardized outcomes) and multivariable mixed effect models, adjusted for age and sex (for other outcomes).

Results

Among the 106 participants (53 males) who completed the 2-year program, mean age at baseline was 10.9 years (SD=3.2). After 2 years, zBMI and diastolic zBP decreased by 0.30SD (95% CI: −0.44; −0.16) and 0.43SD (95% CI: −0.65; −0.23), respectively. Participants improved %body and %trunk fat, lipid profile, aerobic and anaerobic fitness levels, and physical capacity (p&lt;0.02). No changes in systolic zBP nor in fasting plasma glucose were observed.

Conclusion

Our findings showed improved zBMI, cardiometabolic outcomes, physical fitness, and capacity among children at risk of CVD, suggesting that CIRCUIT is a promising intervention.

Engaging New Parents in the Development of a Peer Nutrition Education Model Using Participatory Action Research

This study investigated the implementation model and research methods of a peer education program for new parents focused on infant feeding and nutrition. Two hundred and sixty-nine parents with an infant aged birth to two years old were invited to become co-researchers in a Participatory Action Research (PAR) study over three years. Data included focus group and online participant meeting transcripts, social media data, correspondence between the implementation team and peer educators, and field notes. All data were consolidated regularly and discussed by project participants and the research team. After each PAR cycle, structured content analysis was conducted, informing the next iteration of the implementation model and research methods. Participating parents were highly engaged in child feeding peer-to-peer education, but felt more effective and comfortable being considered as a child-feeding information resource sharer or 'champion' rather than a formal peer educator. Similarly, quantitative data collection was only effective when it was integrated seamlessly into the implementation model. PAR methodology suited the diversity and dynamic real-life study setting, facilitating substantial improvements to the peer nutrition intervention model and data collection methods. Our study demonstrated that a genuine collaboration between health professionals and participants to implement research in practice can achieve both intervention outcomes and research aims.

Changes in body composition and cardiometabolic risk factors in relation to the reduction in body mass index in adolescents with obesity

INTRODUCTION

there are controversial data in relation to the reduction in body mass index standard deviation score (BMI-SDS) needed to improve adiposity in the pediatric population with obesity. The aim of this work was to determine the minimum variation in BMI-SDS required to improve the values of adiposity markers and cardiometabolic risk factors in growing adolescents with obesity.

METHODS

a longitudinal study consisting of clinical evaluation (waist circumference, waist-to-height ratio, fat mass index, and blood pressure) and blood testing (insulin resistance and lipid profile) was conducted in 350 adolescents with obesity (152 boys and 198 girls) aged 10.2-14.3 years who went through a combined intervention (12 months).

RESULTS

a decrease in SDS-BMI ≤ 0.5 was not associated with any significant improvement in the clinical features and blood testing recorded. A decrease in BMI-SDS > 0.5, and especially if > 1.0, was linked to a significant improvement in adiposity markers. A decrease in BMI-SDS > 0.5 was associated with a significant improvement in insulin resistance, and a decrease in BMI-SDS > 1.0 was associated with a significant decrease in the percentage of patients who showed high values of systolic blood pressure, HOMA-IR, and lipid profile Conclusions: improvement in body composition, insulin resistance, and lipid profile can be observed with reductions in BMI-SDS ≥ 0.5 in obese adolescents, while extended benefits are obtained by losing at least 1.0 BMI-SDS.

A staged approach to address youth unresponsive to initial obesity intervention: a randomized clinical trial

BACKGROUND/OBJECTIVE

Maintenance interventions inherently require BMI improvement to maintain. This overlooks individuals initially unresponsive to obesity interventions. Staged pediatric clinical treatment guidelines were adapted to the school setting to develop an escalated treatment option for individuals initially unresponsive. This staged randomized controlled trial examined differences between escalated treatment (Take CHARGE!) and a maintenance program (PE Planners). Take CHARGE was hypothesized to have greater improvements in BMI as a percentage of the 95th BMI Percentile (%BMIp95) than PE Planners.

SUBJECTS/METHODS

From 2018 to 2020, 171 middle and high schoolers (BMI Percentile ≥ 85) were recruited from a Houston school district to participate in a staged obesity intervention in their physical education (PE) class. After receiving a semester-long intensive lifestyle intervention (ILI) with established efficacy, all participants were randomized to Take CHARGE (n = 85) or PE Planners (n = 86). Take CHARGE escalated the behavioral treatment of obesity received in ILI with more frequent individual sessions, additional opportunities for parental and school staff involvement, and increased mentorship from trained college students. PE Planners allowed participants to decide how they wanted to be active in PE class. Mixed linear modeling examined %BMIp95 overtime between groups. This trial was registered at ClinicalTrials.gov (#NCT04362280).

RESULTS

Participants were 13.63 ± 1.32 years old; 59% were female, and 85% were Hispanic. Among those initially unresponsive to ILI, Take CHARGE had significantly greater decreases in %BMIp95 than PE Planners (β = -0.01, p < 0.01). Conversely, among those initially responsive, Take CHARGE had significantly smaller decreases in %BMIp95 than PE Planners (β = 0.02, p < 0.05). Intention-to-treat analysis had similar results.

CONCLUSIONS

Participant outcomes in semester two differed based on initial response. Individuals responsive to initial intervention were most likely to benefit from a maintenance intervention and those initially unresponsive benefited more from escalated treatment. This indicates the need for staged intervention protocols to better address obesity in the school setting.

A look at engagement profiles and behavior change: A profile analysis examining engagement with the Aim2Be lifestyle behavior modification app for teens and their families

Mobile-Health is increasingly used to deliver lifestyle modification interventions; however, little is known about how users engage with these apps. This study aims to profile how teens engage with Aim2Be- a lifestyles behavior modification app), characterize engagement profiles, and examine which engagement profiles support changes in behaviors (diet, physical activity, screen time and sleep) and changes in the mediators targeted by the app. Data were collected from 301 teens (14.8 years, 49% boys, 68% Caucasian) living in Canada, from March to October 2018, who utilized the Aim2Be app for 4.5 months. App-analytics tracked teen engagement with the app features (selecting aims, completing tasks and quick wins, using the knowledge center and social wall, and accessing the virtual coach). Factor mixture modeling identified the following engagement profiles: Uninvolved (32%) did not use most app features; Dabblers (25%) minimally used the app features; Engaged (24%) had moderate-to-high use of app features; and Keeners (19%) had the highest use of all app features. Regression models showed that teens were more engaged with Aim2Be if their parents were involved and if they participated with their mothers and/or an educated parent. Finally, Keeners significantly improved on most mediators of behavior change and increased their fruit and vegetable intake. The findings suggest that parental engagement supported teen engagement of the Aim2Be app and high engagement was needed to support behavior change among teens. Gaining a greater understanding of the features that appeal to teens is necessary to support behavior change.

The impact of a low-calorie, low-glycemic diet on systemic lupus erythematosus: a systematic review

BACKGROUND

Diet plays a critical role in Systemic Lupus Erythematosus (SLE) patients, impacting on the microbiota composition and, consequently, on the immune response. The objective was to analyze and verify the diet effect on SLE patients.

METHODS

This is a systematic review performed at the Evidences-based Health Lab, Escola Superior em Ciências da Saúde, Brasília (DF), Brazil. In March, 2021, five databases, and grey literature, through JSTOR, Open Grey, and Google Scholar were searched. Randomized Clinical Trials in which SLE patients with calorie restricted, low glycemic index or other diet involving the joint adequacy of these aspects, compared with placebo or different types of diet, were included.

RESULTS

It was identified in the databases 758 articles; 132 were duplicated; 616 references were screened, and 604 were excluded. After reading the title and abstract, 12 articles were included for full-text reading. After the full-text reading, three studies were included for quantitative analysis. The diet improved the quality of life at 6 (MD 16.30; 5.91;26.69) and 12 weeks (MD 14.60; 0.88;28.32). The GRADE was used to evaluate the quality of evidence.

CONCLUSION

There is low evidence that the diet has a positive impact on the quality of life of SLE patients. Trial registration PROSPERO-CRD4202012208.

Adolescent obesity treatments: news, views, and evidence

Obesity is a complex and multifactorial disease that is influenced by physiological, environmental, socioeconomic, and genetic factors. In recent decades, this serious disease has impacted a large number of adolescents as a result of lifestyle factors. A lack of exercise and the consumption of excessive calories from an inadequate diet are the main contributors to adolescent obesity. However, genetic and hormonal factors might also play a role. The short- and long-term consequences of this disease include chronic issues such as type 2 diabetes and cardiovascular disorders and an increase in early mortality rates. Although it is a serious disease, obesity in adolescents can be controlled with diet and exercise. When these lifestyle changes do not obtain the expected results, we can intensify the treatment by adding medication to the practice of diet and exercise. Additionally, for more severe cases, bariatric surgery can be an option. The purpose of this review is to clarify the current epidemiology, risks, and comorbidities and discuss news about the main treatments and the necessary improvements in this context.

Special Considerations for Healthy Lifestyle Promotion Across the Life Span in Clinical Settings: A Science Advisory From the American Heart Association

At a population level, engagement in healthy lifestyle behaviors is suboptimal in the United States. Moreover, marked disparities exist in healthy lifestyle behaviors and cardiovascular risk factors as a result of social determinants of health. In addition, there are specific challenges to engaging in healthy lifestyle behaviors related to age, developmental stage, or major life circumstances. Key components of a healthy lifestyle are consuming a healthy dietary pattern, engaging in regular physical activity, avoiding use of tobacco products, habitually attaining adequate sleep, and managing stress. For these health behaviors, there are guidelines and recommendations; however, promotion in clinical settings can be challenging, particularly in certain population groups. These challenges must be overcome to facilitate greater promotion of healthy lifestyle practices in clinical settings. The 5A Model (assess, advise, agree, assist, and arrange) was developed to provide a framework for clinical counseling with consideration for the demands of clinical settings. In this science advisory, we summarize specific considerations for lifestyle-related behavior change counseling using the 5A Model for patients across the life span. In all life stages, social determinants of health and unmet social-related health needs, as well as overweight and obesity, are associated with increased risk of cardiovascular disease, and there is the potential to modify this risk with lifestyle-related behavior changes. In addition, specific considerations for lifestyle-related behavior change counseling in life stages in which lifestyle behaviors significantly affect cardiovascular disease risk are outlined. Greater attention to healthy lifestyle behaviors during every clinician visit will contribute to improved cardiovascular health.
