Guidelines for treating child and adolescent obesity: A systematic review

Behavior-change lifestyle interventions for the treatment of obesity in children and adolescents: A scoping review

Behavior-change lifestyle interventions are fundamental in children and adolescent obesity management. This scoping review discusses optimal behavior-change lifestyle interventions in the treatment of overweight and obesity in children and adolescents. A literature search on diet, physical activity, and behavioral intervention for obesity treatment in children and adolescents aged 0-19 years was conducted in the Cochrane Library, MEDLINE (OVID), EMBASE, and ClinicalTrials.gov. Systematic reviews and meta-analyses with randomized controlled trials (RCTs) published in English from June 2016 to November 2022 were retrieved to identify recent advancements. Obesity outcomes included body weight, body mass index (BMI), BMI z-score, and fat percentage, among others. The 28 located reviews included: four studies on diet therapy; five on physical activity (exercise training); one on sedentary activities; 18 on multicomponent behavior-change lifestyle interventions, including three that incorporated gaming; three with eHealth, mobile health (mHealth), or telehealth, with one in each category; and two on motivational interviewing. Behavior-change lifestyle interventions to reduce obesity in children and adolescents were associated with moderate effects, with low-quality evidence for diet therapy and high-quality evidence for exercise training, both for weight or BMI reduction. Long-term intensive multicomponent behavioral interventions with parental involvement demonstrated better effects.

Usability of the BigO system in pediatric obesity treatment: A mixed-methods evaluation of clinical end-users

Objective

To assess technical usability of the BigO app and clinical portal among diverse participants and explore the overall user experiences of both.

Methods

Methods included technical usability testing by measuring the relative user efficiency score (RUS) for the app and measuring Relative User Efficiency (RUE) using the 'think aloud' method with the clinical portal. Qualitative approaches involved focus groups with adolescent app users and semi-structured one-to-one interviews with clinician participants. Thematic analysis was applied to analyze qualitative data.

Participants

Clinical participants consisted of adolescents seeking treatment for severe obesity and were invited via telephone/face to face to attend technical usability testing and a focus group. Healthcare professionals (HCPs) and researchers using the BigO clinical portal interface were invited to participate in usability testing and semi-structured interviews.

Results

From 14 families invited to attend, seven consented to join the study and four adolescents (mean age=13.8 (SD 0.8) years) participated. Additionally, six HCPs and one pediatric obesity researcher took part. RUS for adolescents indicated that the tasks required of them via myBigO app were feasible, and technically efficient. No user-related errors were observed during tasks. Technical barriers reported by adolescents included notifications of battery optimization, misunderstanding image annotation language, and compatibility challenges with certain phone models. RUS for the HCPs and researcher indicated that basic technical skills are a potential barrier for clinical portal use and qualitative findings revealed that clinical users wanted a logging option for monitoring goals and providing feedback on the portal.

Conclusion

Our study provided valuable formative findings from clinical end-users in Ireland indicating that adolescents being treated for obesity rated myBigO app as usable, acceptable and that it may assist other key stakeholders to understand food marketing and to monitor dietary and physical activity behaviors. Several key suggestions for future iterations of the clinical portal were provided to enhance its value in pediatric obesity treatment.

Registration and management of children with overweight by general practitioners in The Netherlands

BACKGROUND

General practitioners (GPs) form the gateway to healthcare in numerous European countries. Their role in addressing and managing overweight/obesity in children is crucial. In Dutch guidelines, GPs are encouraged to proactively address weight-related issues during patient consultations, regardless of the initial reason of the visit.

OBJECTIVE(S)

To examine the frequency, management and follow-up of GP visits of children for overweight/obesity and the identification by GPs of these children presenting with other complaints.

METHODS

A retrospective cohort study. Health records from 2012-2021 in the Rijnmond Primary Care Database (RPCD) of children aged 2-18 with overweight/obesity who visited the GP were analysed. Children were categorised into two groups: those visiting for weight-related issues (group 1) and those visiting for other complaints but identified as overweight or obese by GPs (group 2). Data on patient demographics, reasons for contact, and management strategies were extracted.

RESULTS

From the 120,991 children, 3035 children with documented overweight or obesity were identified, 208 were excluded. The study population comprised 2827 individuals: 55% belonging to group 1, 45% to group 2. The frequency of first visits remained stable at approximately 0.5% visits per total person-years each year. Group 1 received more referrals (74%) and follow-up consultations (45.5%) than group 2 with 17% referrals and 19.7% follow-up consultations.

CONCLUSION

This study highlights a concerning difference in the management of the two groups. Strategies for effective management of overweight in children and the GP's role, warrant further investigation. Especially when overweight is not the primary reason for visit.

Design, synthesis and structure-activity relationship of novel 2-pyrimidinylindole derivatives as orally available anti-obesity agents

Due to the emerging global epidemic of obesity, developing safe and effective agents for anti-obesity is urgently needed. Our previous study found that 2-pyrimidinylindole derivative Wd3d exhibited potential anti-obesity activity. Herein, to further optimize the potential moiety, structural modifications were proceeded for two rounds in this study. Firstly, we designed, synthesized, and evaluated 36 new derivatives of 2-pyrimidinylindole scaffold with different substituents on the indole ring and pyrimidine ring to investigate their structure-activity relationship (SAR). Then, analogs with potent activity had the aldehyde group replaced with the acylhydrazone group to reduce cytotoxicity and improve metabolic stability. Detailed SAR studies and animal evaluation experiments led to the discovery of the compound 9ga, which significantly reduced TG accumulation with an EC50 value of 0.07 μM and showed relatively low cytotoxicity with an IC50 value of around 24 μM. Oral administration of 9ga effectively prevented the excessive growth of body weight and lessened fat mass as well as liver mass, decreased lipid accumulation in the liver and blood, and improved the heart injury parameter in the diet-induced obesity mouse model significantly better than Wd3d. A mechanism study showed that 9ga regulated the lipid metabolism during early adipogenesis by inhibiting PPARγ pathway. In conclusion, our study further highlights the anti-obesity potential of 2-pyrimidinylindole derivatives in diet-induced obesity.

How close are children with obesity to becoming an adult with chronic illnesses?

OBJECTIVES

Childhood obesity has become a global threat due to its serious negative consequences. We aimed to determine the patterns of metabolic syndrome and cardio-metabolic risk factors in Turkish children with obesity.

METHODS

We examined 169 schoolchildren with obesity in April and May 2019 in Samsun, Turkey. After clinical evaluation and anthropometric measurements, fasting blood samples were collected to measure total cholesterol, low and high-density lipoprotein, fasting blood glucose, triglycerides, and insulin levels.

RESULTS

The proportion of those who met the metabolic syndrome criteria in boys was 14.3%, but it was twice as high in girls (28.2%). The most prevalent component of cardio-metabolic risk factor was increased waist circumference (96.4%) followed by a high homeostasis model assessment insulin resistance index (74.6%) and high blood pressure (29.0%). While the average high-density lipoprotein was higher in boys than in girls, on the contrary, insulin, HbA1c, and homeostasis model assessment insulin resistance concentrations were higher in girls. The prevalence of dyslipidemia was also higher in girls (67.1%) than in boys (47.6%), as were all impaired metabolic syndrome components.

CONCLUSIONS

One in five children with obesity was at risk of metabolic syndrome. For early intervention and prevention, children with obesity should be monitored in terms of cardio-metabolic risk factors, but obese girls are more prioritized.

Special considerations for the child with obesity: An Obesity Medicine Association (OMA) clinical practice statement (CPS) 2024

Background

This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) details assessment and management of the child with overweight or obesity. The term "child" is defined as the child between 2 and 12 years of age. Because children are in a continual state of development during this age range, we will specify when our discussion applies to subsets within this age range. For the purposes of this CPS, we will use the following definitions: overweight in the child is a body mass index (BMI) ≥ 85th and <95th percentile, obesity in the child is a BMI ≥95th percentile, and severe obesity is a BMI ≥120% of the 95th percentile.

Methods

The information and clinical guidance in this OMA Clinical Practice Statement are based on scientific evidence, supported by medical literature, and derived from the clinical perspectives of the authors.

Results

This OMA Clinical Practice Statement provides an overview of prevalence of disease in this population, reviews precocious puberty in the child with obesity, discusses the current and evolving landscape of the use of anti-obesity medications in children in this age range, discusses the child with obesity and special health care needs, and reviews hypothalamic obesity in the child.

Conclusions

This OMA Clinical Practice Statement on the child with obesity is an evidence based review of the literature and an overview of current recommendations. This CPS is intended to provide a roadmap to the improvement of the health of children with obesity, especially those with metabolic, physiological, psychological complications and/or special healthcare needs. This CPS addresses treatment recommendations and is designed to help the clinician with clinical decision making.

Practical guidelines for eating disorder risk mitigation in patients undergoing obesity treatment for the pediatric provider

PURPOSE OF REVIEW

Pediatric obesity is a growing concern globally. Patients with a history of overweight/obesity often experience stigmatization, especially in the healthcare setting, and are at increased risk of developing psychological comorbidities including eating disorders. This review appraises the most recent studies evaluating eating disorder risk in youth undergoing treatment for obesity, identifies gaps in the literature, and offers practical guidelines to pediatric providers regarding the management of this population.

RECENT FINDINGS

Recent studies suggest that structured weight management programs may decrease the risk of and/or improve symptoms of certain eating disorders such as binge eating disorder and bulimia nervosa. There is a paucity of research on some components of obesity management such as obesity pharmacotherapeutics and eating disorder risk.

SUMMARY

Children and adolescents with obesity are a psychologically vulnerable population with increased risk for the development of eating disorders. Further study is needed to evaluate general risk in the setting of specialized and primary care obesity interventions and develop appropriate screening and mitigation tools. Some evidence-based strategies can aid pediatric providers in both weight management and eating disorder prevention and risk assessment.

Direct costs for outpatient excess body weight treatment in Brazilian children and adolescents attending a public children's hospital

OBJECTIVE

To estimate the direct costs of treating excess body weight in children and adolescents attending a public children's hospital.

METHODS

This study analyzed the costs of the disease within the Brazilian Unified Health System (SUS) for 2,221 patients with excess body weight using a microcosting approach. The costs included operational expenses, consultations, and laboratory and imaging tests obtained from medical records for the period from 2009 to 2019. Healthcare expenses were obtained from the Table of Procedures, Medications, Orthoses/Prostheses, and Special Materials of SUS and from the hospital's finance department.

RESULTS

Medical consultations accounted for 50.6% (R$703,503.00) of the total cost (R$1,388,449.40) of treatment over the period investigated. The cost of treating excess body weight was 11.8 times higher for children aged 5-18 years compared to children aged 2-5 years over the same period. Additionally, the cost of treating obesity was approximately 4.0 and 6.3 times higher than the cost of treating overweight children aged 2-5 and 5-18 years, respectively.

CONCLUSION

The average annual cost of treating excess body weight was R$138,845.00. Weight status and age influenced the cost of treating this disease, with higher costs being observed for individuals with obesity and children over 5 years of age. Additionally, the important deficit in reimbursement by SUS and the small number of other health professionals highlight the need for restructuring this treatment model to ensure its effectiveness, including a substantial increase in government investment.

Management for children and adolescents with overweight and obesity: a recommendations mapping

BACKGROUND

Childhood obesity is a global public health issue, and the status of clinical practice guidelines (CPGs) as instruction manuals for the management of childhood obesity remains unclear. This study aims to identify and apprise the methodological and reporting quality of CPGs focused on childhood obesity and provide an overview of key recommendations.

METHODS

Databases and websites reporting guidelines were searched from January, 2018 to September, 2023. The methodological quality was graded using the AGREE II, and RIGHT was used to assess the reporting completeness.

RESULTS

Among the six included CPGs, two were rated as high quality and considered "Recommended" and three were reported no less than 80%. CPGs included 184 recommendations cover diagnosis, assessment and management of complications, interventions and prevention. The diagnostic criteria for children with obesity over 2 years of age are based on normative BMI percentiles, depending on sex and age. CPGs recommended the delivery of multi-component behavior-changed interventions included controlling diet and increasing physical activity. Pharmacological interventions and bariatric surgery are considered as complementary therapies.

CONCLUSION

CPGs for childhood obesity should emphasize the impact of psychological factors and consider the provision of interventions from multiple settings, and could consider the role of complementary alternative therapies.

IMPACT

Six guidelines have been published in the past 5 years focusing children obesity. Recommendations covered diagnosis, multiple intervention and prevention. Guidelines should focus on the role of complementary alternative therapies. Guidelines should emphasize the impact of psychological factors. Guidelines should consider the provision of interventions from multiple settings.

Clinical practice guidelines for the management of overweight and obesity published internationally: A scoping review

With the increasing prevalence of obesity placing additional demands on healthcare systems, many jurisdictions and professional bodies have developed clinical practice guidelines to support practitioners in the management of people with overweight and obesity. This scoping review aimed to identify key features of contemporary guidelines for the clinical management of overweight and obesity. Searches of MEDLINE, Guidelines International Network's international guidelines library, and other grey literature sources identified 38 guidelines of 18 countries and one region published since 2010. Guidelines were developed by committees (n = 36, 95%) that comprised knowledgeable experts (n = 36, 95%) and were multidisciplinary (n = 33, 87%), with limited consumer representation (n = 11, 29%). Guideline documentation incorporated review questions (n = 23, 61%), systematic reviews (n = 25, 66%), evidence grading systems (n = 33, 87%), processes for reaching consensus (n = 19, 50%), and guideline review details (n = 28, 74%). Treatment approaches included in most guidelines were nutrition and physical activity (n = 38, 100%), psychology (n = 37, 97%), pharmacotherapy (n = 32, 84%), and bariatric surgery (n = 31, 82%). Most guidelines targeted populations based on age (n = 30, 79%). Guidelines contained recommendations for pregnancy (n = 12, 32%), older adults (n = 9, 24%), and people with eating disorders (n = 8, 21%). Future guidelines would benefit from involvement of consumers including groups known to be at increased risk of overweight and obesity, targeted guidance for at risk groups, and consideration of weight bias and stigma.

Health equity in pediatrics: Current concepts for the care of children in the 21st century (Dis Mon)

This is an analysis of important aspects of health equity in caring for children and adolescents written by a multidisciplinary team from different medical centers. In this discussion for clinicians, we look at definitions of pediatric health equity and the enormous impact of social determinants of health in this area. Factors involved with pediatric healthcare disparities that are considered include race, ethnicity, gender, age, poverty, socioeconomic status, LGBT status, living in rural communities, housing instability, food insecurity, access to transportation, availability of healthcare professionals, the status of education, and employment as well as immigration. Additional issues involved with health equity in pediatrics that are reviewed will include the impact of the COVID-19 pandemic, behavioral health concepts, and the negative health effects of climate change. Recommendations that are presented include reflection of one's own attitudes on as well as an understanding of these topics, consideration of the role of various healthcare providers (i.e., community health workers, peer health navigators, others), the impact of behavioral health integration, and the need for well-conceived curricula as well as multi-faceted training programs in pediatric health equity at the undergraduate and postgraduate medical education levels. Furthermore, ongoing research in pediatric health equity is needed to scrutinize current concepts and stimulate the development of ideas with an ever-greater positive influence on the health of our beloved children. Clinicians caring for children can serve as champions for the optimal health of children and their families; in addition, these healthcare professionals are uniquely positioned in their daily work to understand the drivers of health inequities and to be advocates for optimal health equity in the 21st century for all children and adolescents.

Addressing child and adolescent obesity management in Ireland: identifying facilitators and barriers in clinical practice

Background

Ireland's Model of Care for the Management of Overweight and Obesity outlines a plan for treating adolescent and child obesity (CO). However, engagement with key stakeholders is required to support its implementation and improve health services.

Aim

This study aims to map the perceived barriers and facilitators related to CO management across healthcare settings, professional disciplines, and regions in the Republic of Ireland (ROI).

Materials and methods

An online cross-sectional survey of registered healthcare professionals (HPs), designed to adhere to the Consolidated Framework for Implementation Research (CFIR), was co-developed by a project team consisting of researchers, healthcare professionals, and patient advocates. The survey was pilot tested with project stakeholders and distributed online to professional groups and via a social media campaign, between September 2021 and May 2022, using "SurveyMonkey." Data were summarised using descriptive statistics and thematic analyses. Themes were mapped to the CFIR framework to identify the type of implementation gaps that exist for treating obesity within the current health and social care system.

Results

A total of 184 HPs completed the survey including nurses (18%), physicians (14%), health and social care professionals (60%), and other HPs (8%). The majority were female (91%), among which 54% reported conducting growth monitoring with a third (32.6%) giving a diagnosis of paediatric/adolescent obesity as part of their clinical practice. Nearly half (49%) of the HPs reported having the resources needed for clinical assessment. However, 31.5% of the HPs reported having enough "time," and almost 10% of the HPs reported having no/limited access to suitable anthropometric measurement tools. Most HPs did not conduct obesity-related clinical assessments beyond growth assessment, and 61% reported having no paediatric obesity training. CFIR mapping identified several facilitators and barriers including time for clinical encounters, suitable materials and equipment, adequate training, perceived professional competency and self-efficacy, human equality and child-centredness, relative priorities, local attitudes, referral protocols, and long waiting times.

Conclusions

The findings provide actionable information to guide the implementation of the Model of Care for the Management of Overweight and Obesity in Ireland. Survey findings will now inform a qualitative study to explore implementation barriers and facilitators and prioritise actions to improve child and adolescent obesity management.

Body Composition in Fussy-Eating Children, with and without Neurodevelopmental Disorders, and Their Parents, Following a Taste Education Intervention

Fussy eaters may have an increased risk of becoming overweight or obese as adolescents, with fussy eating and weight status also correlating with neurodevelopmental disorders (NDs) such as autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD). Further, maternal and children's weight status relationships are well-established. In this study, we analyzed the body composition of parent-child dyads using bioelectrical impedance analysis (BIA). Fifty-one children aged 8-12 years, with an ND (n = 18) and without (n = 33), and their parents, participated in a 7-week food-based Taste Education intervention with 6-month follow-up. The paired t-test was used to compare differences in body composition based on children's ND status. In logistic regression analysis, odds of children being in the overweight/obese or overfat/obese categories increased by a factor of 9.1 and 10.6, respectively, when having NDs, adjusting for parents' BMI (body mass index) or fat percentage (FAT%). Children with NDs and their parents had significantly higher mean BMI-SDS (BMI standard deviation score) and FAT% at pre-intervention than children without NDs and their parents. Mean BMI-SDS and FAT% lowered significantly between time points for children with NDs and their parents but not for children without NDs or their parents. The findings underline the need for additional exploration into the relationships between children's and parents' body composition based on children's ND status.

The Effectiveness of a Physical Literacy-Based Intervention for Increasing Physical Activity Levels and Improving Health Indicators in Overweight and Obese Adolescents (CAPACITES 64)

Recently, the concept of Physical Literacy (PL) has emerged as a key concept for promoting active behavior and improving health indicators in adolescents. Overweight and obese adolescents have a low level of Physical Activity (PA), low cardiorespiratory capacity, and high Body Fat percentage (%BF). However, the development of PL in the interest of health improvement has never been studied in overweight and obese adolescents. The objective of this study was to evaluate the impact of an intervention developing PL in overweight and obese adolescents in order to increase their (PA) and improve their health. The study was a prospective, single-arm, non-randomized interventional study. The intervention brings together different actions in PA and dietary education in different adolescent living environments. The study took place over a 9-month period with two data collection times (0; +9 months) and measured Body Mass Index (BMI) and BMI z score, %BF and Skeletal Muscle Mass (%SMM), Moderate-to-Vigorous intensity Physical Activity (MVPA) by accelerometry, CRF, as well as PL by the CAPL-2 tool. Thirteen adolescents (age 11.7 (±1.09) years old) improved their PL scores (+8.3 (±9.3) pts; p ≤ 0.01). BMI z score (-0.3 (±0.3), p ≤ 0.01), their %BF (-3.8 (±4.9); p ≤ 0.01), their CRF (+1.5 (±1.7) mL·min·kg-1; p ≤ 0.01), and their MVPA (+4.6 (±13.7) min/day; p = 0.36). Initiating multidimensional interventions to develop PL in overweight and obese adolescents may be a promising prospect to enable an increase in their MVPA and improve their long-term health. Longer-term randomized controlled interventional studies are needed to confirm these findings.

Pediatric obesity - time to act as early as possible

There has been a global increase in the average body mass index (BMI) in children and an alarming trend of increasing weight among the youngest children in recent decades. Childhood excess weight and obesity result in premature adult mortality and morbidity. Obesity is not only a risk factor for other diseases but is also a complex, multifactorial disease in its own right, linked to a genetic predisposition influenced by an increasingly permissive environment from intrauterine life throughout childhood and adolescence into adulthood. Knowledge of the prevalence of obesity from the earliest life stages and its trajectory is essential to raise awareness of the risks at each stage and to indicate the potential age of prevention and intervention. Taking effective anti-obesity measures in children, both preventive and therapeutic, is now a necessity, with successful interventions used to decrease body weight and thus reduce health consequences. Identified risk factors in the first 1,000 days of life and even earlier, before conception, suggest that this is a key period for the development of overweight and obesity, and it appears to be the best time for preventive action. The growing phenomenon of obesity among children requires not only prevention but also integral treatment. Lifestyle change intervention programs are considered key to the treatment of childhood obesity. Obesity trajectories, the higher effectiveness of applied interventions observed in younger age groups, and the dependence of the risk of developing complications on the duration of obesity confirm the need for early diagnosis and treatment of obesity in children from an early age. The main aim should be to prevent the onset of obesity, thus reducing the future health, social, and financial consequences.
