Effects of multidisciplinary interventions on weight loss and health outcomes in children and adolescents with morbid obesity

The age of the obesity onset is a very important factor for the development of metabolic complications and cardiovascular risk in children and adolescents with severe obesity

Severe obesity defined as BMI value corresponding to an adult > 40 kg/m2 affects 1-5% of children and adolescents in Europe. The purpose of this study was to assess the occurrence of cardiovascular risk factors in children and adolescents with severe obesity. The analysis included 140 patients (75 female) at the mean age of 14 ± 2.1 SD (range 10-18) years (all recruited in 4 regional reference centers in Poland). Severe obesity was defined as BMI > 35 kg/m2 (children 6-14 years), and BMI > 40 kg/m2 (> 14 years). Fasting plasma samples have been obtained in all patients, and OGTT was performed in all patients. The metabolic risk factors were defined as high blood pressure (BP > 90 percentile for height, age, and sex), HDL cholesterol < 1.03 mmol/L, TG ≥ 1.7 mmol/L, and hyperglycemic state (fasting blood glucose > 5.6 mmol/L, or blood glucose 120' after oral glucose load > 7.8 mmol/L). Additionally, the MetS z-score was calculated using Metabolic Syndrome Severity Calculator. One hundred twenty-four (89%) participants presented with high BP, 117 (84%) with abnormal lipid profile, and 26 with the hyperglycemic. Only 12 (9%) were free of metabolic complications. More than 60% of patients had more than one cardiovascular risk factor. The high BP was significantly associated with the severity of obesity (F = 9.9, p = 0.002). Patients with at least one metabolic complication presented with significantly younger age of the onset of obesity (the mean age of the patients with no overt obesity complications was 10 years, while the mean age of those who presented at least one was 4.7 ± 3.5 SD years (p = 0.002)). A significant positive association between in the value of the Mets BMI z-score with age was observed (R = 0.2, p < 0.05). There were no differences between girls and boys regarding Mets BMI z-score (1.7 ± 0.8 vs 1.7 ± 0.7, p = 0.8).Conclusions: The most common metabolic risk factor in children and adolescents with severe obesity was high BP. The most important factor determining presence of obesity complications, and thus the total metabolic risk, seems to be younger (< 5 years) age of onset of obesity. What is Known? • It is estimated that 1-5% of children and adolescents in Europe suffer from severe obesity corresponding to an adult BMI > 40 kg/m2, and it is the fastest growing subcategory of childhood obesity. • Children with severe obesity face substantial health risk that may persist into adulthood, encompassing chronic conditions, psychological disorders and premature mortality. What is new: • The most common complication is high BP that is significantly associated with the severity of obesity (BMI z-score), contrary to dyslipidemia and hyperglycemic state, which do not depend on BMI z-score value. • The most important factor determining presence of obesity complications, and thus the total metabolic risk, seems to be younger (< 5 years) age of onset of obesity.

The relationship between modifiable lifestyle behaviours and self-reported health in children and adolescents in the United Kingdom

Obesity, along with its associated health issues, is closely tied to lifestyle habits. While certain elements affecting childhood health, such as genetics and ethnicity, are beyond individuals' control, there exists modifiable lifestyle behaviours that can facilitate healthier living. This study employed multiple regression analysis to investigate the relationship between specific modifiable lifestyle behaviours and self-reported health. The independent variables considered included days of moderate to vigorous physical activity (MVPA), fruit and vegetable consumption, breakfast frequency, school night sleep duration, and non-school night sleep duration. These variables were chosen for their practical modifiability within participants' daily lives. The analysis revealed a highly significant overall model (F(13,11363) = 191.117, p < .001), explaining 17.9% of the variance in self-reported health. Notably, higher MVPA levels were associated with improved self-reported health (B = 0.136 to 0.730, p < .001). Additionally, regular breakfast consumption and increased fruit and vegetable intake exhibited positive associations with self-reported health (B = 0.113 to 0.377, p < .001), while girls reported lower self-reported health (B = -0.079, p < .001). School night sleep duration was positively linked to self-reported health (B = 0.071, p < .001). Furthermore, a dose-response relationship between MVPA, dietary habits, and health was identified. These findings hold substantial potential for public health campaigns to promote healthy behaviours and prevent chronic diseases in young individuals. It is imperative to emphasise that all the variables considered in this study are readily modifiable aspects of individuals' lives, offering a promising avenue for personal health and well-being enhancement.

School physical activity modes on BMI among adolescents with overweight or obesity: The mediation role of participation willingness

OBJECTIVES

To analyze the mode of school physical activity, the relationship with obesity, and participation willingness and behavior in the relationship between modes of school physical activity and BMI in students with overweight or obesity.

DESIGN

Cross-sectional study.

SAMPLE

Data from the 2014 Physical Fitness and Health Surveillance of Chinese School Students was used, wherein physical measurements and questionnaires of 3476 middle school students were collected.

MEASUREMENTS

Physical measurements and questionnaires were completed. Latent profile analysis and mediated effects analysis were conducted using Mplus 8.3 and IBM SPSS 26.0 for data description and statistical analysis.

RESULT

After latent profile analysis divided into poor (9.35%), medium (65.16%), and good (25.49%) groups of school physical activity, among junior middle school students, medium (OR = 0.428, 95% CI = 0.259-0.707, p = .001) and good (OR = 0.448, 95% CI = 0.255-0.718, p = .002) groups were positive for controlling overweight. Among students with overweight or obesity, participation willingness mediated the relationship between the mode of school physical activity and BMI, with effect coefficients of -0.120 (95% CI = -0.264 to -0.016) and -0.240 (95% CI = -0.426 to -0.099).

CONCLUSIONS

School physical activity modes have a positive effect only on preventing and controlling overweight in junior middle school students. For middle school students with obesity, weight-specific measures should be considered for their prevention and control.

Nutrient Deficiency After Bariatric Surgery in Adolescents: A Systematic Review and Meta-Analysis

OBJECTIVE

This systematic review and meta-analysis study aimed to estimate changes in blood nutrient concentrations and nutrient deficiencies in adolescents following bariatric surgery.

METHODS

We searched PubMed, Scopus, and the Web of Science to find studies published between January 2000 and August 2023. Observational studies reporting the mean blood concentration of nutrients before and after bariatric surgery or the proportion of nutrient deficiencies after the surgery in healthy adolescents were selected.

RESULTS

Fifteen studies were included. Gastric bypass and sleeve gastrostomy were the most common types of surgery. Vitamin D, iron, or ferritin, vitamin B12, calcium, and folic acid were the most studied nutrients, respectively. Other nutrients examined in the studies included zinc, phosphorus, and albumin. The serum ferritin increased by 21 mcg/L (95% CI = 10.0, 32.0 mcg/L) after the surgery, but there were no significant alterations in other nutrients. The postoperative prevalence of low albumin, ferritin, vitamin D, and vitamin B12 levels was 10%, 49%, 41%, and 20%, respectively. Also, 23% had an iron deficiency, and 10% had a calcium deficiency after bariatric surgery.

CONCLUSIONS

The serum ferritin level increased following bariatric surgery in adolescents. Vitamin D and ferritin deficiencies were estimated to be present in more than one-third of adolescents after the surgery.

The complex associations between adiposity, fitness, mental wellbeing and neurocognitive function after exercise: A randomized crossover trial in preadolescent children

The aim of the present study was to examine the associations of adiposity and fitness on the preadolescent brain's response to acute exercise. In a sample of 58 children (ages 8-10; 19 females), demographic measures of age, sex, IQ, puberty, and socioeconomic status were considered. Children participated in a randomized crossover study, whereby they completed two different interventions; seated rest or treadmill walking, counterbalanced across participants. Associations between adiposity measures (standardized body mass index [BMI-Z], whole body percent fat [%Fat], visceral adipose tissue [VAT]), cardiorespiratory fitness measures (VO2max and Fat-Free VO2) were assessed on self-reported measures of mental wellbeing, and cognitive performance (response accuracy, reaction time) and neuroelectric (P3 amplitude and latency) indices of a Go/NoGo task following both exercise and rest interventions. Higher adiposity (whole-body percent fat, BMI-Z) was associated with higher trait anxiety (P's≤0.05) and disordered eating (P's≤0.05) scores. Higher fitness (VO2max) was associated with lower childhood depression scores (P=0.02). Regression analyses yielded specific post-exercise neurocognitive associations with adiposity-related (VAT, BMI-Z), and fitness-related (FF-VO2) outcomes, after controlling for post-rest neurocognitive outcomes. VAT was positively associated with post-exercise P3 ERP Latency for the Go task (P≤0.001); BMI-Z was negatively associated with P3 ERP amplitudes for the Go task (P's≤0.005); FF-VO2 was negatively associated with P3 ERP latency for the Go/NoGo task (P's≤0.05), and positively associated with NoGo task accuracy (P≤0.001). Overall, adiposity and fat-free fitness measures yield sensitive and differential associations with neurocognitive performance after exercise and after rest interventions.

Effects of applying a multivariate training program on physical fitness and tactical performance in a team sport taught during physical education classes

Introduction

A multivariate training program could be a pedagogical choice to improve physical and tactical performance in a team sport taught during physical education classes at different levels of education. Thus, the aim of this study was to verify the effects of applying a multivariate training program on physical fitness and tactical performance during the teaching of a basketball didactic unit in basic and secondary education.

Methods

Seventy-five students from a Portuguese school, with an average age of 15.02 ± 1.31 years, included forty-two students from basic school and thirty-three students from secondary school. The FITescola® test battery was used to assess physical fitness (i.e., sit-ups, push-ups, horizontal impulse, shuttle test, 40 m sprint, agility 4 × 10 m). The Game Performance Assessment Instrument (GPAI) was used to assess students' tactical performance for each player's game performance during a 20-minute 3 vs. 3 match. The GPAI variables were decision making index (DMI), skill execution index (SEI), support actions index (SI), and adaptability index (AI). During a basketball didactic unit teaching, the students were randomly divided into two groups, a control group that will not carry out the training program and an experimental group that will carry out a strength training program, high intensity explosive exercises and activities based on small-sided games (SSG) for 6 weeks. The two groups were evaluated in two moments: before the application of the training program and after the application of the training program regarding changes in physical fitness and tactical performance. The independent samples t-test (samples from two groups) and paired sample Test (for the same group) were applied for pre and post-assessment comparisons.

Results

All indexes present significant differences between basic and secondary students in the pre- and post-assessment tests with small effects (t = -6.54 to -4.82, Δ = -27.57 to -0.16, p<0.05-p< 0.001, d = 0.78-1.05).

Discussion

The results allow to conclude that in a school environment, a well-structured multivariate training program can effectively improve students' tactical skills, increasing their physical conditioning levels.

Mixed methods feasibility and usability testing of a childhood obesity risk estimation tool

BACKGROUND

A Childhood Obesity Risk Estimation tool (SLOPE CORE) has been developed based on prediction models using routinely available maternity and early childhood data to estimate risk of childhood obesity at 4-5 years. This study aims to test the feasibility, acceptability and usability of SLOPE CORE within an enhanced health visiting (EHV) service in the UK, as one context in which this tool could be utilised.

METHODS

A mixed methods approach was used to assess feasibility of implementing SLOPE CORE. Health Visitors (HVs) were trained to use the tool, and in the processes for recruiting parents into the study. HVs were recruited using purposive sampling and parents by convenience sampling. HVs and parents were invited to take part in interviews or focus groups to explore their experiences of the tool. HVs were asked to complete a system usability scale (SUS) questionnaire.

RESULTS

Five HVs and seven parents took part in the study. HVs found SLOPE CORE easy to use with a mean SUS of 84.4, (n = 4, range 70-97.5) indicating excellent usability. Five HVs and three parents took part in qualitative work. The tool was acceptable and useful for both parents and HVs. Parents expressed a desire to know their child's risk of future obesity, provided this was accompanied by additional information, or support to modify risk. HVs appreciated the health promotion opportunity that the tool presented and felt that it facilitated difficult conversations around weight, by providing 'clinical evidence' for risk, and placing the focus of the conversation onto the tool result, rather than their professional judgement. The main potential barriers to use of the tool included the need for internet access, and concerns around time needed to have a sensitive discussion around a conceptually difficult topic (risk).

CONCLUSIONS

SLOPE CORE could potentially be useful in clinical practice. It may support targeting limited resources towards families most at risk of childhood obesity. Further research is needed to explore how the tool might be efficiently incorporated into practice, and to evaluate the impact of the tool, and any subsequent interventions, on preventing childhood obesity.

Self-control training supplementing inpatient multidisciplinary obesity treatment in children and adolescents

Research points to self-control as a possible mechanism for facilitating health behaviour and weight loss. The dual pathway model underpins the role of strong bottom-up reactivity towards food and weak top-down executive functions in obesity. Despite flourishing lab studies on attention bias modification or inhibition trainings, relatively few focused on training both processes to improve self-control in children and adolescents in inpatient multidisciplinary obesity treatment (MOT). Being part of the WELCOME project, this study investigated the effectiveness of Brain Fitness training (using the Dot Probe and Go/No-Go) as an adjunct to inpatient MOT in 131 Belgian children and adolescents. Changes in self-control (performance-based inhibitory control and attention bias as well as self-reported eating behaviour) in the experimental group were compared to sham training. Multiple Imputation was used to handle missing data. Inhibitory control and external eating improved over time (pre/post/follow-up), but we found no evidence for a significant interaction between time and condition. Future research should pay more attention to the role of individual variability in baseline self-control, sham training, and ecological validity of self-control training to improve real-life health behaviour and treatment perspectives for children and adolescents with weight problems.

Cardiovascular endurance and psychosocial health predict short- and long-term BMI-SDS reduction: results from the CHILT III program

This longitudinal study analyzes data from the Children's Health Interventional Trial (CHILT) III, an 11-month juvenile multicomponent weight management program. The objective is to identify predictors of changes in body mass index standard deviation scores (BMI-SDS), so as to further enable the advancement of existing interventions with sustained impact. This study's sample consists of 237 children and adolescents with obesity (8-17 years, 54% girls) participating in the CHILT III program between 2003 and 2021. Anthropometrics, demographics, relative cardiovascular endurance (W/kg), and psychosocial health (i.e., physical self-concept and self-worth) were assessed at program entry ([Formula: see text]), end ([Formula: see text]), and one-year follow-up ([Formula: see text]; n = 83). From [Formula: see text] to [Formula: see text], the mean BMI-SDS was reduced by -0.16 ± 0.26 units (p < 0.001). Media use and cardiovascular endurance at baseline and improvements in endurance and self-worth over the course of the program predicted changes in BMI-SDS (adj. R² = 0.22, p < 0.001). From [Formula: see text] to [Formula: see text], mean BMI-SDS increased ([Formula: see text], p = 0.005). Changes in BMI-SDS from [Formula: see text] to [Formula: see text] were associated with parental education, improvements in cardiovascular endurance and physical self-concept, and BMI-SDS, media use, physical self-concept, and endurance level at program end (adj. R² = 0.39, p < 0.001).  Conclusions: This study highlights the need for comprehensive, sustainable weight management approaches, in order to sustain the initial treatment benefits. In this context, improvements in cardiovascular endurance and psychosocial health could be essential strategies to pursue in practice, as they significantly predicted reductions in BMI-SDS - both pre- to post-intervention and at follow-up.

TRIAL REGISTRATION

DRKS00026785; date of registration: 13.10.202, retrospectively registered.

WHAT IS KNOWN

• Childhood obesity is associated with the onset of noncommunicable diseases, many of which are likely to carry into adulthood. Thus, effective weight management strategies for affected children and their families are vital. However, achieving lasting positive health outcomes with multidisciplinary weight management programs remains challenging.

WHAT IS NEW

• According to this study, short- and longer-term BMI-SDS reductions are associated to cardiovascular endurance and psychosocial health. These factors should therefore be given even greater consideration in weight management strategies, as they may be important not only in themselves but also for long-term weight loss (maintenance).

Comparison of an online versus conventional multidisciplinary collaborative weight loss programme in type 2 diabetes mellitus: A randomized controlled trial

AIM

The aim of this study was to examine the effect of an online multidisciplinary weight loss management programme.

METHODS

Between July 2016 and July 2017 this randomized controlled trial recruited patients in Nanjing, China who were living with type 2 diabetes mellitus and who were obese or overweight and randomized them to online versus conventional groups. All participants were managed by a multidisciplinary team. The experimental group was managed using the Why Wait WeChat Platform for Weight Reduction Management.

RESULTS

There were 55 and 52 participants in the online and conventional groups, respectively. The decreases in fasting blood glucose (-4.26 vs. -2.99 mmol/L), 2-h postprandial blood glucose (-4.48 vs. -2.68 mmol/L) and glycated haemoglobin (-22.11 vs. -6.21 mmol/mol) were more pronounced in the online compared to conventional group (all P < 0.05). After the intervention, self-management ability parameters, including diet control, foot care and total score, were improved in the online group compared with the conventional group, as well as all indexes of quality of life (all P < 0.05).

CONCLUSION

The online multidisciplinary weight loss management programme improved blood glucose in obese or overweight patients living with type 2 diabetes mellitus. Self-management ability parameters (including diet control, foot care and total score) and quality of life were improved in the online group compared with the conventional group.

Recreational Soccer Training Effects on Pediatric Populations Physical Fitness and Health: A Systematic Review

This systematic review analyzed the effects of recreational soccer programs on physical fitness and health-related outcomes in youth populations. Studies were sought in the following databases: (i) PubMed, (ii) Scopus, (iii) SPORTDiscus, and (iv) Web of Science. The eligibility criteria included (1) population: youth (<18 years old) populations with no restrictions on sex or health condition; (2) intervention: exposure to a recreational soccer training program of at least four weeks duration; (3) comparator: a passive or active control group not exposed to a recreational soccer training program; (4) outcomes: physical fitness (e.g., aerobic, strength, speed, and change-of-direction) or health-related measures (e.g., body composition, blood pressure, heart rate variability, and biomarkers); (5) study design: a randomized parallel group design. The search was conducted on 6 September 2022 with no restrictions as to date or language. The risk of bias was assessed using the PEDro scale for randomized controlled studies. From a pool of 37,235 potentially relevant articles, 17 were eligible for inclusion in this review. Most of the experimental studies revealed the beneficial effects of recreational soccer for improving aerobic fitness and its benefits in terms of blood pressure and heart-rate markers. However, body composition was not significantly improved by recreational soccer. The main results revealed that recreational soccer training programs that are implemented twice a week could improve the generality of physical fitness parameters and beneficially impact cardiovascular health and biomarkers. Thus, recreational soccer meets the conditions for being included in the physical education curriculum as a good strategy for the benefit of the general health of children and young people.

Assessment of mental health problems among adolescents in Sri Lanka: Findings from the cross-sectional Global School-based Health Survey

Background and Aims

Mental health condition among adolescents is a leading cause of health-related disability in Sri Lanka. The study aims to estimate the prevalence and evaluate the associated risk factors in three major mental health domains-loneliness, anxiety and suicidal ideation-among Sri Lankan adolescents.

Methods

We conducted a secondary analysis of cross-sectional data of 3262 adolescents from the Global School-based Health Survey (GSHS) conducted by the WHO in 2016. We modeled the binary outcome variables using multivariable logistic regression models with exposures representing demography, food habits, personal hygiene, behavior, substance abuse, parental and social engagement of the respondents.

Results

We estimated the prevalence of loneliness, anxiety and suicidal ideation as 30.8% (95% CI: 29.3, 32.5), 20.2% (95% CI: 18.8, 21.6) and 3.7% (95% CI: 3.1, 4.4), respectively, and the overall prevalence as 40.3% (95% CI: 38.6, 42.0). Mental health problems were more prevalent among females than males. Engagement with parents and close friends, adequate nutritional intake and physically active lifestyles reduced the risk of common mental health problems. Exposure variables like food insecurity, truancy, second-hand smoking, physical fight, and being bullied increased adolescents' risk of reported psychological problems.

Conclusions

We conclude that the prevalence of mental health problems in the Sri Lankan adolescent population was higher than the global average. Results suggest that future policy decisions to mitigate mental health problems among Sri Lankan adolescents should incorporate an integrated approach involving the individual, family and community to promote positive home and school environments combined with an active and healthy lifestyle.

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.

Medical treatment of weight loss in children and adolescents with obesity

Obesity remains one of the biggest health problems both in adults and children. Lifestyle modification, including diet and exercise, continues to be the mainstay of obesity prevention and treatment. Unfortunately, lifestyle modifications are often unsuccessful. Pharmacological treatment of obesity in pediatric patients can be applied in selected cases, and not before evidence of failure of the multidisciplinary lifestyle intervention. In this narrative review, we revised the most up-to-date evidence on medical treatment of weight loss in children and adolescents with obesity, including FDA- or EMA-approved and -experimented, not approved, drugs for pediatric population. Multidisciplinary treatment of childhood obesity, regulation of appetite control, energy balance and body weight were also discussed, in order to clarify the indications and mechanism action of drugs. Despite a substantial number of medications used for the treatment of obesity in adults, a limited number of drugs are approved by the drug regulatory agencies for pediatric population. Further research is needed to evaluate the efficacy and safety of novel pharmacological approaches for treatment of pediatric obesity in order to optimize weight management for children and adolescents and limit the development obesity-related comorbidities.

Perceptions of a family-based lifestyle intervention for children with overweight and obesity: a qualitative study on sustainability, self-regulation, and program optimization

BACKGROUND

Family-based lifestyle interventions (FBLIs) are an important method for treating childhood weight problems. Despite being recognized as an effective intervention method, the optimal structure of these interventions for children's overweight and obesity has yet to be determined. Our aim was to better understand participants' (a) implementation of behaviour strategies and long-term outcomes, (b) perceptions regarding the optimal structure of FBLIs, and (c) insights into psychological concepts that may explain the success of these programs.

METHODS

Purposive sampling was used to recruit participants. We conducted focus groups as well as one-to-one interviews with parents (n = 53) and children (n = 50; aged 7-13, M = 9.4 yr, SD = 3.1) three months following their involvement in a 10-week, multi-component, FBLI involving education and activities relating to healthy nutrition, physical activity, and behavior modification. Using an interpretivist approach, a qualitative study design was employed to examine participant experiences.

RESULTS

We identified three higher-order categories: (a) participants' program experiences and perceptions (b) lifestyle changes post-program, and (c) recommendations for optimizing family-based programs. Themes identified within these categories included (a) support and structure & content, (b) diet and physical activity, and (c) in-program recommendations and post-program recommendations.

CONCLUSIONS

We identified several challenges that can impair lasting behavior change (e.g., physical activity participation) following involvement in a FBLI. On optimizing these programs, participants emphasized fun, interactive content, interpersonal support, appropriate educational content, and behavior change techniques. Concepts rooted in motivational theory could help address calls for greater theoretical and mechanistic insight in FBLIs. Findings may support research advancement and assist health professionals to more consistently realize the potential of these interventions.

Progress in pediatric obesity: new and advanced therapies

PURPOSE OF REVIEW

In this review, we discuss new medical and surgical options for the treatment of children and adolescents with obesity. We review the impact of COVID-19 on this vulnerable population. We also discuss the recent availability of screening tests for rare genetic causes of obesity.

RECENT FINDINGS

COVID-19 increased the prevalence of obesity among children and adolescents. This population is at increased risk for severe disease. The field of pediatric obesity has benefited from the approval of two new antiobesity medications: liraglutide and setmelanotide. We discuss indications for their use. New guidelines for surgical options for the treatment of children and adolescents with obesity are reviewed. These options are increasingly used as part of the comprehensive care for these children.

SUMMARY

The epidemic of childhood obesity continues. COVID-19 and the associated isolation contributed to the problem. However, promising new medical and surgical therapies and screening tests for rare genetic causes of obesity are available. These new diagnostic and therapeutic options bring renewed enthusiasm to the treatment of children and adolescents with obesity and increased recognition that obesity is a chronic disease starting in childhood deserving intervention to prevent consequences.

Multidisciplinary Treatment for Childhood Obesity: A Two-Year Experience in the Province of Naples, Italy

Childhood obesity must be faced through an integrated multi-level preventive approach. This study was aimed at assessing the adherence and the outcomes of an outpatient service for childhood obesity treatment activated in the province of Naples, Italy, throughout a 2-year follow-up period. At first visit (T0), weight, height, waist circumference, and body composition of children were assessed, together with sociodemographic features and physical activity levels of children and parents. Anthropometric and body composition parameters of children were measured at 6 ± 3 months (T1) and 12 ± 3 months (T2). A total of 451 non-related children who accessed the service were analyzed: 220 (48.7%) of them returned at least once (attrition rate 51.3%). Returner outpatients showed higher age (p = 0.046) and father’s educational level (p = 0.041) than non-returner ones. Adherence to the treatment was found to be related to father’s (Rho = 0.140, p = 0.005) and mother’s (Rho = 0.109, p = 0.026) educational level. All the outcomes improved between T0 and T1 (p < 0.001), while only body mass index (BMI) decreased significantly at T2. Changes in BMI-SDS were associated with baseline value (OR 0.158, 95%CI 0.017−0.298, p = 0.029). The multidisciplinary approach seems to be promising to treat childhood obesity in this geographic context. Lower parents’ educational level should be considered as an attrition determinant.

Multivariate Training Programs during Physical Education Classes in School Context: Theoretical Considerations and Future Perspectives

Physical Education plays a fundamental role in promoting healthy habits and lifestyles, as well as in the development of individual and cognitive skills. To date, several investigations have reported positive effects on indicators of physical fitness, motor proficiency, and creativity as a result of specific training programs during Physical Education classes. However, the effects of multivariate training programs on the improvement of the aforementioned skills remain unclear in the literature. Through this brief review, the benefit of applying multivariate training programs during Physical Education classes on indicators of physical fitness, motor proficiency and creativity was critically analyzed. A narrative approach was applied to summarize the availed research as following: (i) theoretical background; (ii) research gaps/issues; (iii) subject explanation about multivariate training programs in Physical Education; and (iv) practical application and further research. The evidence reported in this regard may be useful for the development of multivariate training programs that simultaneously enable the improvement of indicators of physical fitness, motor proficiency and creativity. However, there is still no consensus in the literature on the best strategies (i.e., type of program, duration, intensity) to enhance motor proficiency and creativity in the context of Physical Education classes using multivariate training programs.

The Side-Effects of the COVID-19 Pandemic: Increased BMI z-Score in Children with Overweight and Obesity in a Personalised Lifestyle Intervention One Year after the Start of the Pandemic in The Netherlands

Background: Early research showed weight gain in children during the COVID-19 pandemic. Objective: To compare changes in BMI z-score of children with overweight and obesity in a personalised lifestyle intervention before and during the pandemic. Methods: Changes in BMI z-score half a year (T6) and twelve months (T12) after the first lockdown were included for 71 children in the ‘2020 during COVID’ group and compared to 48 children in the ‘2019 before COVID’ group, using a marginal model for repeated measures (model 1). Model 2 corrected for lifestyle intervention characteristics, and model 3 corrected additionally for family characteristics. Results: The mean difference in BMI z-score change was significantly different at T12 (+0.07 in 2020 versus −0.09 in 2019, p = 0.022). Model 3 showed significant differences in BMI z-score change at both T6 (+0.15, p = 0.024) and T12 (+0.18, p = 0.016). This model also defined ‘having a mother with obesity’ (+0.13, p = 0.019) and the frequency of no-show consultations (+0.41 per missed consultation per month, p = 0.025) as related factors. Conclusions: Lifestyle intervention in children with overweight and obesity is less successful in decreasing BMI z-score during the COVID-pandemic. Identified risk factors for less success could contribute to identifying children with higher risks for, and possibly prevent, BMI z-score increase.

Diet quality scores associated with improved cardiometabolic measures among African American adolescents

BACKGROUND

The Reversing the Negative cardiovascular Effects on Weight (ReNEW) Clinic is a prospective cohort study in children and adolescents (≤21 years) at the Johns Hopkins Children's Center.

METHODS

Cross-sectional analysis between diet quality using the Alternative Healthy Eating Index (AHEI-2010), pro-inflammatory potential using the Children's Dietary Inflammatory Index (C-DII), and cardiometabolic outcomes. AHEI-2010 and C-DII scores were assessed by median intake determined from the sample distribution and associated with cardiometabolic measures using linear regression models. Changes in measures were evaluated in a sub-sample of participants invited to attend follow-up visits due to the presence of hypertensive blood pressure (n = 33).

RESULTS

Participants (n = 90) reported an average energy intake of 1790 kcal/day (SD ± 734), AHEI-2010 score of 55.04 (SD ± 9.86) (range: 0 to 110) and C-DII score of -0.12 (±0.86) (range -5 to 5). Participants with higher quality/anti-inflammatory diets trended towards more favorable cardiometabolic measures at baseline. Among the sub-sample (n = 33), there was a significant reduction in total energy (m = -302 kcal/day; p-value= 0.03) but no change in AHEI-2010 (p-value = 0.73) or C-DII score (p-value = 0.85) over follow-up.

CONCLUSIONS

Despite stable diet quality scores, outpatient dietary and behavioral counseling may be an effective tool to reduce energy intake in youth with overweight/obesity and elevated blood pressure.

IMPACT

Diet quality scores among obese, hypertensive, African American adolescents were low and reflect a pro-inflammatory diet. Reported intake was negligible for fruits, whole grains, nuts, and legumes, and well above the daily limit for sodium and saturated fat. Participants with high quality/anti-inflammatory diet quality scores trended toward improved cardiometabolic measures. Outpatient dietary counseling resulted in reduced total energy intake.

Difference in Insulin Resistance Assessment between European Union and Non-European Union Obesity Treatment Centers (ESPE Obesity Working Group Insulin Resistance Project)

INTRODUCTION

The obesity epidemic has become one of the most important public health issues of modern times. Impaired insulin sensitivity seems to be the cornerstone of multiple obesity related comorbidities. However, there is no accepted definition of impaired insulin sensitivity.

OBJECTIVE

We hypothesize that assessment of insulin resistance differs between centers.

METHODS

The ESPE Obesity Working Group (ESPE ObWG) Scientific Committee developed a questionnaire with a focus on the routine practices of assessment of hyperinsulinemia and insulin resistance, which was distributed through Google Docs platform to the clinicians and researchers from the current ESPE ObWG database (n = 73). Sixty-one complete responses (84% response rate) from clinicians and researchers were analyzed: 32 from European Union (EU) centers (representatives of 14 countries) and 29 from Non-EU centers (representatives from 10 countries). Standard statistics were used for the data analysis.

RESULTS

The majority of respondents considered insulin resistance (IR) as a clinical tool (85.2%) rather than a research instrument. For the purpose of IR assessment EU specialists prefer analysis of the oral glucose tolerance test (OGTT) results, whereas non-EU ones mainly use Homeostatic Model Assessment of Insulin Resistance (HOMA-IR; p = 0.032). There was no exact cutoff for the HOMA-IR in either EU or non-EU centers. A variety of OGTT time points and substances measured per local protocol were reported. Clinicians normally analyzed blood glucose (88.52% of centers) and insulin (67.21%, mainly in EU centers, p = 0.0051). Furthermore, most participants (70.5%) considered OGTT insulin levels as a more sensitive parameter of IR than glucose. Meanwhile, approximately two-thirds (63.9%) of the centers did not use any cutoffs for the insulin response to the glucose load.

CONCLUSIONS

Since there is no standard for the IR evaluation and uniform accepted indication of performing, an OGTT the assessment of insulin sensitivity varies between EU and non-EU centers. A widely accepted standardized protocol is needed to allow comparison between centers.

Development and Implementation of a Pilot Integrative Day Hospital Program for Youth with Severe Obesity and Mental Health Issues

Background: Adolescents with severe obesity and comorbid mental health issues are the most resistant to traditional weight management approaches and have poor treatment outcomes. Our objective was to implement and evaluate a pilot day hospital treatment program for adolescents with severe obesity, or risk for severe obesity, and significant mental health comorbidities. Methods: This was a prospective cohort study of adolescents 12-18 years of age with severe obesity (BMI >99th percentile), or at risk for severe obesity, and comorbid mental health issues. The intervention, focused on healthy lifestyle and mental health support, was implemented within an existing psychiatric day hospital at a pediatric quaternary care hospital. Anthropometric and mental health measures were analyzed pre- and postintervention. Results: Thirty-two adolescents with a mean age of 14.9 years [standard deviation (SD) 1.6] participated in the pilot integrative day hospital program for a mean duration of 5.2 months (SD 2.3). Eleven participants had primary severe obesity and comorbid mental health conditions (obesity subgroup) and 21 participants had primary mental illness and were at risk for obesity (psychiatry subgroup). We did not observe a significant difference between BMI pre- and postprogram among adolescents in both subgroups. In other words, adolescents in both subgroups achieved weight maintenance. Fear in losing control of overeating and/or being seen by others when eating decreased significantly in the obesity subgroup [mean difference (MD) 0.99; 95% confidence interval (CI): 0.27 to 1.71]. There was a significant decrease in participant-reported depression symptom severity, both overall and within program subgroups. Quality-of-life scores of study participants improved significantly within the obesity subgroup (MD -12.31; 95% CI: -21.69 to -2.93), but not within the psychiatry subgroup (MD -6.35; 95% CI: -13.37 to 0.67). Conclusions and Implications: A day hospital model of care may result in weight maintenance, decreased eating concerns, and improved mental health in adolescents with severe obesity or risk for severe obesity, and significant mental health comorbidities.

Frequent Medical Supervision Increases the Effectiveness of a Longitudinal Multidisciplinary Body Weight Reduction Program: A Real-World Experience in a Population of Children and Adolescents with Obesity

Regular medical supervision represents a fundamental component of the clinical management of obesity. In fact, when frequently supplied it reduces the risk of failure associated with any body weight reduction program (BWRP), resulting in body weight gain. The aim of the present study was to establish the potential beneficial effects of increasing medical supervision on weight loss and other auxometric and cardiometabolic parameters in a population of children and adolescents with obesity (n = 158; F/M = 94/64; age range 9.7-17.3 years; body mass index, BMI = 37.8 ± 6.9 kg/m²), followed up for one year in a real-world setting, after and before a 3-week in-hospital BWRP. Weight loss was significantly associated with medical supervision and changes in several auxometric and cardiometabolic parameters such as fat mass, fat-free mass, waist and hip circumferences, total and LDL cholesterols, triglycerides, glucose, insulin, HOMA-IR, systolic blood pressure and IDF criteria for the diagnosis of metabolic syndrome. As expected, weight loss and, congruently, medical supervision, were significantly higher in responsive and stable subjects than in those belonging to the non-responsive group and in responsive subjects than those belonging to the stable group. While weight loss was significantly higher in subjects having class 2 and 3 obesity than those belonging to class 1 obesity group, medical supervision was significantly higher in subjects having class 3 than those having class 1 obesity. Weight loss was significantly higher in subjects suffering from metabolic syndrome than those without; nevertheless, no significant difference was found in medical supervision between these groups. Finally, sex was associated with no differences in weight loss and medical supervision. In conclusion, based on the results of a real-world experience, frequent medical supervision increases the weight loss associated with a longitudinal multidisciplinary BWRP, with a parallel improvement of a set of auxometric and cardiometabolic parameters. Prospectively, incentivising regular medical supervision should reduce the risk of BWRP failure and body weight gain, thus contributing to counteract the detrimental transition from simple obesity to metabolic syndrome in pediatric patients.

The 3Ds - Discussion, diagnosis and direction: Elements for effective obesity care by healthcare professionals

BACKGROUND

The care of people with obesity is often suboptimal due to both physician and patient perceptions about obesity itself and clinical barriers. Using data from the ACTION-IO study, we aimed to identify factors that might improve the quality of obesity care through adoption of the 3D approach (Discussion, Diagnosis and Direction [follow-up]) by healthcare professionals (HCPs).

METHODS

An online survey was completed by HCPs in 11 countries. Exploratory beta regression analyses identified independent variables associated with each component of the 3D approach.

RESULTS

Data from 2,331 HCPs were included in the statistical models. HCPs were significantly more likely to initiate weight discussions and inform patients of obesity diagnoses, respectively, if (odds ratio [95% confidence interval]): they recorded an obesity diagnosis in their patient's medical notes (1.59, [1.43-1.76] and 2.16 [1.94-2.40], respectively); and they were comfortable discussing weight with their patients (1.53 [1.39-1.69] and 1.15 [1.04-1.27]). HCPs who reported feeling motivated to help their patients lose weight were also more likely to initiate discussions (1.36 [1.21-1.53]) and schedule follow-up appointments (1.21 [1.06-1.38]). By contrast, HCPs who lacked advanced formal training in obesity management were less likely to inform patients of obesity diagnoses (0.83 [0.74-0.92]) or schedule follow-up appointments (0.69 [0.62-0.78]).

CONCLUSION

Specific actions that could improve obesity care through the 3D approach include: encouraging HCPs to record an obesity diagnosis; providing tools to help HCPs feel more comfortable initiating weight discussions; and provision of training in obesity management.

Effect of Protein-Rich Breakfast on Subsequent Energy Intake and Subjective Appetite in Children and Adolescents: Systematic Review and Meta-Analysis of Randomized Controlled Trials

Breakfast has been labeled “the most important meal of the day”, especially for children and adolescents. Dietary protein intake may benefit and regulate appetite and energy balance. However, few meta–analyses have been conducted to examine the effect of protein–rich (PR) breakfast on both children and adolescents. This meta–analytic study was conducted to examine the effect of consuming a PR breakfast on short–term energy intake and appetite in children and adolescents. PubMed, Embase, Cochrane Central Register of Controlled Trials, China Biology Medicine disc (CBM), and China National Knowledge Infrastructure (CNKI) were searched for randomized controlled trials (RCTs) published in January 1990–January 2021. The inclusion criteria applied were RCTs in children and adolescents (7–19 year) comparing PR breakfast consumption with normal protein (NP)/traditional breakfast consumption. Finally, ten studies were included in the analysis, eight studies examined the effect of consuming PR breakfast on SEI (n = 824), and nine studies examined the effect on appetite (fullness = 736, hunger = 710). Our meta-analysis using the random–effects model shows that participants assigned to consume PR breakfast had lower SEI (MD, −111.2 kcal; 95% CI: −145.4, −76.9), higher fullness (MD, 7.4 mm; 95% CI: 6.0, 8.8), and lower hunger (MD, −8.5 mm; 95% CI: −9. 7, −7.3) than those assigned to consume NP/traditional breakfast. However, there was considerable inconsistency across the trial results. Our review suggests that the consumption of PR breakfast could be an excellent strategy for weight management by declining SEI and suppressing appetite, and provides new evidence of the relationship between energy balance and obesity. However, since most eligible studies were of low quality, the results ought to be interpreted cautiously.

Current status of multi-disciplinary paediatric weight management services in Australia

AIM

To identify multi-disciplinary paediatric weight management services currently available in Australia and determine gaps in service provision for children and adolescents with obesity.

METHODS

Surveys were distributed to 17 identified Australian multi-disciplinary paediatric weight management services. A representative from each service was asked to complete an online survey regarding service and patient characteristics, assessment and management practices, and professional development approaches.

RESULTS

Representatives from 16 multi-disciplinary paediatric weight management services completed the survey. Fourteen services were based in major metropolitan cities and two in regional areas. Fourteen services provided care to pre-school aged children (0-4 years old), 15 to primary school aged children (5-12 years old) and 13 to high school aged children (13-18 years old). The number of patients seen per year per service ranged from 20 to 250 and duration of waiting lists ranged from 2 months to more than 12 months.

CONCLUSIONS

The current availability and accessibility of multi-disciplinary paediatric weight management services is inadequate to service Australian children and adolescents with obesity, particularly those with severe obesity and those in rural and remote communities. To better address the issue of paediatric obesity, establishment of additional multi-disciplinary services, training for health-care professionals and monitoring of the provision of evidence-based care is urgently needed.

Underdiagnosis of obesity in pediatric clinical care settings among children born preterm: a retrospective cohort study

BACKGROUND

Neonatal care of preterm infants may include dietary approaches such as high calorie formulas to promote physical growth. However, continuing growth-promoting strategies beyond the point of necessity, coupled with poverty and food insecurity which are more common among families of children born preterm, may increase the risk of obesity. Because children born preterm tend to have more pressing health conditions that require ongoing care, obesity may go undiagnosed by providers.

METHODS

This retrospective cohort study included 38,849 children (31,548 term, 7301 preterm) born from 2010 to 2015, who received clinical care at a large pediatric medical center (Ohio, USA). Electronic medical record data, linked to Ohio birth certificates, were used to identify children with measured obesity (≥2 weight-for-length values ≥95th percentile before 24 months of age or BMI values ≥95th percentile at or after 24 months of age). Children were considered to have diagnosed obesity if their medical record had an obesity-related phrase or billing code recorded. Modified Poisson regression was used to compare risk of obesity undiagnosis among obese children born preterm versus at term.

RESULTS

In total, 13,697 children had measured obesity, 10,273 (75%) of which were undiagnosed. Children born preterm with measured obesity were 8% more likely to be undiagnosed compared to children born at term (adjusted relative risk = 1.08 95% CI 1.05, 1.11). The risk was slightly higher for preterm children born to white women or born to women with higher educational attainment. For both groups, Primary Care and subspecialist clinics were the most common settings for undiagnosed obesity (74.9% and 16.8% of undiagnosed cases, respectively).

CONCLUSIONS AND RELEVANCE

Preterm birth was associated with increased risk of undiagnosed obesity in early childhood. This highlights the need to enhance obesity screening in the preterm population and to further explore reasons for this disparity.

Effectiveness of a Weight Loss Program Using Digital Health in Adolescents and Preadolescents

Objective: To identify an efficacious intervention on treating adolescents with overweight and obesity, this might result in health benefits. Methods: Adolescents with overweight or obesity aged 10-17 years with BMI percentile ≥85th were included in this historical observational analysis. Subjects used an entirely remote weight loss program combining mobile applications, frequent self-weighing, and calorie restriction with meal replacement. Body weight changes were evaluated at 42, 60, 90, and 120 days using different metrics including absolute body weight, BMI, and BMI z-score. Chi-square or Fisher exact tests (categorical variables) and Student's t-test (continuous variables) were used to compare subjects. Results: In total, 2,825 participants, mean age 14.4 ± 2.2 years, (54.8% girls), were included from October 27, 2016, to December 31, 2017, in mainland China; 1355 (48.0%) had a baseline BMI percentile ≥97th. Mean BMI and BMI z-score were 29.20 ± 4.44 kg/m² and 1.89 ± 0.42, respectively. At day 120, mean reduction in body weight, BMI, and BMI z-score was 8.6 ± 0.63 kg, 3.13 ± 0.21 kg/m², and 0.42 ± 0.03; 71.4% had lost ≥5% body weight, 69.4% of boys and 73.2% of girls, respectively. Compared with boys, girls achieved greater reduction on BMI z-score at all intervals (p < 0.004 for all comparisons). Higher BMI percentile at baseline and increased frequency of use of the mobile application were directly associated with more significant weight loss. Conclusions: An entirely remote digital weight loss program is effective in facilitating weight loss in adolescents with overweight or obesity in the short term and mid term.

The Effectiveness of School-Based Interventions on Obesity-Related Behaviours in Primary School Children: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

School-based interventions are promising for targeting a change in obesity-related behaviours in children. However, the efficacy of school-based interventions to prevent obesity remains unclear. This review examined the effectiveness of school-based interventions at changing obesity-related behaviours (increased physical activity, decreased sedentary behaviour and improved nutrition behaviour) and/or a change in BMI/BMI z-score. Following PRISMA guidelines, seven databases were systematically searched from 1 January 2009 to 31 December 2020. Two review authors independently screened studies for eligibility, completed data extraction and assessed the risk of bias of each of the included studies. Forty-eight studies met the inclusion criteria and were included in a narrative synthesis. Thirty-eight studies were eligible for inclusion in a meta-analysis. The findings demonstrate that interventions in children when compared to controls resulted in a small positive treatment effect in the control group (2.14; 95% CI = 0.77, 3.50). There was no significant effect on sedentary behaviour, energy intake and fruit and vegetable intake. Significant reductions were found between groups in BMI kg/m2 (-0.39; 95% CI = -0.47, -0.30) and BMI z-score (-0.05; 95% CI = -0.08, -0.02) in favour of the intervention. The findings have important implications for future intervention research in terms of the effectiveness of intervention components and characteristics.

Perceptions of non-successful families attending a weight-management clinic

OBJECTIVE

This study seeks to understand family's perceptions of their care at a paediatric weight management service, with a view to informing service improvement.

DESIGN

A qualitative service review conducted via semistructured interviews with parents (n=11) and children (n=3) who attended the clinic. The recruitment was open to all, but those who were not succeeding in their weight-loss goals self-selected to participate. Self-Determination Theory was used as a framework to explore families' experiences of the clinic.

SETTING

Recruitment occurred during clinical appointments and interviews were conducted over the phone in the days following the appointments.

PATIENTS

The service sees paediatric patients with a body mass index >99th percentile, with comorbidities or safeguarding concerns.

INTERVENTIONS

The clinic's service includes appointments typically every 2 months, with a multidisciplinary team including consultant endocrinologists, a dietician, a clinical psychologist, a social worker and a clinical nurse specialist.

MAIN OUTCOME MEASURES

Families' feedback on the multi-disciplinary team (MDT) clinic, and their perceptions of how improvements could be made.

RESULTS

Families perceive a lack of autonomy, competency and feel a lack of connectivity both in their lives broadly and within their experience at the clinic.

CONCLUSIONS

Interventions in families struggling with weight improvements should see the clinical team placing more emphasis on working alongside parents to develop young people's sense of self-determination. Expectations must be set that success originates from changes outside of clinical appointments and that the clinical team is in place to support the family's development of sustainable, self-determined lifestyle habits.

Sustainable weight loss over three years in children with obesity: a pragmatic family-centered lifestyle intervention

INTRODUCTION

Childhood obesity has psychological consequences and increases the risk of continuous obesity into adulthood, associated with development of non-communicable disease (e.g. type 2 diabetes). Short-term weight loss intervention studies show good results but long-term studies are limited.

METHODS

One hundred ninety-nine obese children (4-18 years of age), with a BMI-SDS (standard deviation score) above + 2 SDS were enrolled into a multifactorial family-centered lifestyle intervention study. The children had yearly visits in the outpatient clinic for anthropometrics, blood samples and DXA-scans, and 6-8 meeting with community health workers between these visits. The children followed the intervention up to 3 years.

RESULTS

After a follow-up of 26.7 ± 17.5 months a reduction in BMI-SDS of - 0.25 SDS (p < 0.001) was observed. The 57 children who were adherent to the intervention for ≥ 2 years had significantly reduced BMI-SDS compared to the 142 children with shorter intervention (BMI-SDS: - 0.38 ± 0.67 vs. - 0.20 ± 0.50, p = 0.036). All weight loss was accompanied by decrease in fat mass and increase in muscle mass (p < 0.001).

CONCLUSION

The intervention was found to induce long-term reduction in BMI-SDS in obese children, with beneficial change in body composition. Children who followed the intervention the longest had the greatest reduction in BMI-SDS.

Adipocytokine and appetite-regulating hormone response to weight loss in adolescents with obesity: Impact of weight loss magnitude

OBJECTIVE

The aim of this study was to investigate the association between the magnitude of weight loss (WL) and serum concentrations of the main adipocytokines and appetite-regulating hormones in adolescents with obesity.

METHODS

After completion of informed consent,108 adolescents with obesity (14-19 y of age; postpubertal) were submitted to clinical, nutritional, psychological, physical exercise, and physiotherapy support for 1 y. Body composition (BC) and plasma levels of neuropeptides (neuropeptide Y [NPY], agouti-related peptide [AgRP], and α-melanocyte-stimulating hormone [α-MSH]) and leptin were measured at baseline and post-intervention.

RESULTS

After therapy, adolescents who lost <10% body weight and <10% body weight (were compared. Both groups presented improvements in BC and reduced leptin. The Δα-MSH, Δα-MSH/AgRP ratio, and Δα-MSH/NPY ratio were lower and AgRP and NPY variations were higher in the low weight loss group. The leptin concentration was close to normal in the high weight loss only. The ΔWeight, Δα-MSH and Δleptin were associated with body fat loss by multiple linear regressions for all samples.

CONCLUSION

Weight loss >10% seems to reverse obesity-induced hyperleptinemia while stabilizing the neuropeptides that control appetite in adolescents with obesity. We were able to produce a prognostic mathematical model to predict body fat loss using weight, leptin, and α-MSH variations.

Effects of School-Based Exercise and Nutrition Intervention on Body Composition and Physical Fitness in Overweight Adolescent Girls

Regular exercise during school hours is encouraged since childhood obesity has reached epidemic proportions. Moreover, a great majority of adolescents do not meet the recommendations for moderate-to-vigorous physical activity. The present study aimed to determine the effects of school-based high-intensity interval training (HIIT) and nutrition intervention on body composition and physical fitness in overweight adolescent girls. Forty-eight girls were included in the study, of whom 24 (age = 15.5 ± 0.7 years) were randomized to a experimental group (EXP) (HIIT and nutrition intervention school-based program) and 24 (age = 15.7 ± 0.6 years) to a control group (CON) that maintained their usual physical education activities. HIIT consisted of 10 stations of own bodyweight exercise and was done three times per week for eight weeks. Moreover, the EXP participated in the nutrition program led by a nutritionist two times a week. Apart from body composition assessment, participants performed countermovement jump (CMJ), medicine ball throw, hand-grip test, and Yo-Yo Intermittent Recovery Level 1 Test (YYIRT1). A significant effect of group (EXP vs. CON) x time (pre vs. post) interaction was observed for weight [F(1,44) = 7.733; p = 0.008], body mass index [F(1,44) = 5.764; p = 0.020], body fat (in kg) [F(1,44) = 17.850; p < 0.001], and body fat (in %) [F(1,44) = 18.821; p < 0.001]. Moreover, a significant interaction was observed for the medicine ball throw [F(1,44) = 27.016; p < 0.001] and YYIRT1 [F(1,44) = 5.439; p = 0.024]. A significant main effect for time was found for hand grip [F(1,44) = 9.300; p = 0.004] and CMJ [F(1,44) = 12.866; p = 0.001].The present study has demonstrated that just eight weeks school-based HIIT and nutrition intervention, including three sessions a week, can improve body composition and muscular and physical aerobic performance in overweighted adolescent girls.

Is There A Causal Relationship between Childhood Obesity and Acute Lymphoblastic Leukemia? A Review

Simple Summary

The childhood obesity epidemic is impacting tens of millions of children globally. While obesity causes several cancers in adults, its potential role in causing pediatric cancers remains unclear. In this review, we assess the potential contribution of obesity to the development of acute lymphoblastic leukemia (ALL), the most common pediatric cancer. We review the possible mechanisms by which the adipose tissue attracts and protects leukemia cells and how it interferes with the actions of chemotherapies used in ALL treatment. We also examine adipose tissue-secreted molecules and fuels that may support leukemia development. While there are no current definite causal links between obesity and ALL, there are plausible mechanisms that need further investigation to explore the impact of obesity on causing ALL and on impacting treatment outcomes.

Abstract

Childhood obesity is a growing epidemic with numerous global health implications. Over the past few years, novel insights have emerged about the contribution of adult obesity to cancer risk, but the evidence base is far more limited in children. While pediatric patients with acute lymphoblastic leukemia (ALL) are at risk of obesity, it is unclear if there are potential causal mechanisms by which obesity leads to ALL development. This review explores the endocrine, metabolic and immune dysregulation triggered by obesity and its potential role in pediatric ALL’s genesis. We describe possible mechanisms, including adipose tissue attraction and protection of lymphoblasts, and their impact on ALL chemotherapies’ pharmacokinetics. We also explore the potential contribution of cytokines, growth factors, natural killer cells and adipose stem cells to ALL initiation and propagation. While there are no current definite causal links between obesity and ALL, critical questions persist as to whether the adipose tissue microenvironment and endocrine actions can play a causal role in childhood ALL, and there is a need for more research to address these questions.

Adolescent body image: influencing factors and the clinician's role

PURPOSE OF REVIEW

Body image is a crucial part of adolescent development for teens all over the world. Studies show that negative body image impacts many aspects of adolescent health and that anticipatory guidance about body image is important at the annual health maintenance exam visit. Weight bias is closely tied to body image and is associated with negative health effects as well; research shows weight bias is a problem throughout healthcare. The purpose of this review is to discuss influencing factors on adolescent body image and to explore interventions to promote positive body image.

RECENT FINDINGS

Research shows that adolescent body image is shaped by media influence, athletics and personal relationships. Studies have also begun to show that negative and positive body image are separate entities, and that overall health outcomes seem to be better in adolescents with positive body image. In thinking about intervention, there are ways to promote positive body image in the provider--patient interaction, within the school and community, in healthcare education, and at the societal level.

SUMMARY

Body image is an incredibly important aspect of adolescent health, and clinicians should be aware of ways to help promote positive body image in adolescents.

The Effects of Physical Activity and Diet Interventions on Body Mass Index in Latin American Children and Adolescents: A Systematic Review and Meta-Analysis

The objective of this systematic review and meta-analysis is to compare the effect of physical activity only with that of physical activity plus diet interventions on body mass index (BMI) in Latin American children and adolescents. We searched the Medline, Embase, Scopus, Web of Science, and Scielo databases from their inception until March 2020, including studies examining the effect of physical activity or physical activity plus diet interventions on BMI in children and adolescents and based on data from intervention studies. The DerSimonian and Laird method was used to compute a pooled standardized mean difference for BMI in terms of effect size (ES) and respective 95% confidence intervals (CIs). Eighteen studies were included. Analyses were performed based on intervention (four studies were included for physical activity only and four studies were included for physical activity plus diet). In the analysis of physical activity only versus control, there was no effect on BMI (ES = 0.00; 95% CI −0.17–0.17, I² = 0.0%; p = 0.443). In the analysis of physical activity plus diet versus control, there was a decrease in BMI in favour of the intervention group (ES = −0.28; 95% CI −0.42–−0.14, I² = 74.5%; p = 0.001). When ES was estimated considering only the effect in intervention groups, there was no evidence of a decrease in BMI (ES = −0.17; 95% CI −0.44–0.11, I² = 84.5%; p < 0.001) for physical activity only (eight studies). However, there was a statistically significant decrease in BMI (ES = −0.30; 95% CI −0.50–0.11, I² = 95.8%; p < 0.001) for physical activity plus diet (ten studies). Some limitations of this review could compromise our results, but the main limitation that should be stated is the quality of the studies (mainly medium/moderate), especially as physical activity and diet interventions cannot be blinded, compromising the quality of these studies. In summary, this meta-analysis offers evidence that physical activity plus diet interventions produced a reduction in BMI in Latin American children and adolescents, but physical activity only interventions did not.

Are obstructive sleep apnea and sleep improved in response to multidisciplinary weight loss interventions in youth with obesity? A systematic review and meta-analysis

BACKGROUND

Pediatric obesity is closely associated with obstructive sleep apnea (OSA) and short sleep duration. While multidisciplinary weight loss interventions are recommended for pediatric obesity management, the evidence for their effects on OSA severity and overall sleep in youth have not been systematically examined.

OBJECTIVES

To conduct a systematic review and meta-analysis investigating the effects of multidisciplinary weight loss interventions on OSA severity and prevalence, and on overall sleep health in youth with obesity.

METHODS

A systematic search of interventional studies (participants age range: 10-19 yrs) was performed using PubMed, CENTRAL and Embase, from inception to May 2019. The quality of the evidence was assessed using the Cochrane risk of bias tool.

RESULTS

Ten studies were included by the end of the screening process. Ninety percent of the included studies reported a decrease in OSA prevalence post-intervention, and OSA was normalized for 46.2-79.7% of the youth. The meta-analysis comprising seven longitudinal studies revealed significant reductions in apnea-hypopnea index (effect size: -0.51, 95%CI -0.94 to -0.08, p = 0.019), and oxygen desaturation index (effect size: -0.28, 95%CI = -0.50 to -0.05, p = 0.016). Seventy-five percent of the studies reported improved sleep duration in youth with OSA.

CONCLUSIONS

Evidence suggests that multidisciplinary weight loss interventions result in improvements in OSA severity and sleep duration in youth with obesity. Future randomized controlled trials are warranted to better assess and understand the independent implications of weight loss, fat mass decrease and chronic exercise on OSA and sleep health in this population.

Cost-Effectiveness of an Obesity Management Program for 6- to 15-Year-Old Children in Poland: Data from Over Three Thousand Participants

BACKGROUND

Obesity and overweight, including childhood obesity and overweight, pose a public health challenge worldwide. According to the available research findings, long-term interventions focusing on dietary behavior, physical activity, and psychological support are the most effective in reducing obesity in children aged 6-18 years. There are limited studies showing the financial effectiveness of such interventions.

OBJECTIVE

The objective of the present study was to evaluate cost-effectiveness of the 6-10-14 for Health weight management program using pharmacoeconomic indicators, i.e., cost-effectiveness analysis using the incremental cost-effectiveness ratio.

METHODS

We used anthropometric data of 3,081 children included in a 1-year-long intervention with a full financial cost assessment.

RESULTS

The cost of removing a child from the overweight group (BMI >85th percentile) was PLN 27,758 (EUR 6,463), and the cost of removing a child from the obese group (BMI >95th percentile) was slightly lower, i.e., PLN 23,601 (EUR 5,495). Given the obesity-related medical costs calculated in the life-long perspective, these results can be considered encouraging. At the same time, when comparing the total costs per participant with the costs of other interventions, it can be noted that they are similar to the costs of school programs containing more than 1 type of intervention.

CONCLUSIONS

The 6-10-14 for Health program can be considered cost-effective. As a result of committing financial resources in the approximate amount of EUR 1,790 per child, around half of the children participating in the program have improved their weight indicators.

Introducing eccentric cycling during a multidisciplinary weight loss intervention might prevent adolescents with obesity from increasing their food intake: The TEXTOO study

PURPOSE

The present study compared the appetite responses to an inpatient eccentric vs. concentric cycling training programs in adolescents with obesity.

METHODS

24 adolescents with obesity (12-16yrs; Tanner 3-4) followed a 12-week multidisciplinary intervention (Phase1), after which they were randomized to concentric (CON) or eccentric (ECC) training for 12 weeks (Phase2). Assessment of anthropometrics, body composition (DXA), aerobic power (VO_2max), energy (EI) and macronutrient intake, food reward, and subjective appetite were performed at baseline, and after Phase1 (T1) and Phase2 (T2).

RESULTS

Body mass, BMI, and fat mass (FM%) decreased in both groups (p < 0.001). FM% reduction was greater in ECC at T2 (-9.9%). EI did not change in either group at T1, but was greater at T2 relative to T1 in CON only (p < 0.001,+22%). There was no correlation between the change in body mass, FM%, fat-free mass and EI. Hunger (p = 0.002) and desire to eat (p = 0.001) were higher in CON vs. ECC with no time effects nor interactions. Prospective food consumption increased in both groups with no group effect nor interaction. Satiety was not different between groups or over time. In ECC, preference for high-fat foods increased (p = 0.03), and preference (p = 0.004) and implicit wanting (p = 0.016) for sweet foods decreased.

CONCLUSION

Eccentric cycling as part of an inpatient multidisciplinary weight-loss intervention might help prevent increased ad libitum energy intake compared to concentric exercise training in adolescents with obesity, potentially through distinct effects of the food reward system.

Effects of physical activity interventions on the body mass index of children and adolescents in Latin America: a protocol for a systematic review and meta-analysis

INTRODUCTION

In Latin America, the number of children and adolescents who are overweight or obese has significantly increased in recent decades, and this situation has become a major public health concern. To address this problem, several intervention programmes, based on factors such as physical activity and nutrition, have been implemented, and body mass index (BMI) has been widely used as a means of measuring the impact of such interventions. Although some Latin America-based systematic reviews have been performed, there have been no previous meta-analyses of findings regarding the effect of physical activity interventions on BMI. Thus, the objective of the systematic review and meta-analysis will be to provide an up-to-date synthesis of the effects of physical activity interventions on BMI of Latin American children and adolescents aged 4-18 years.

METHODS AND ANALYSIS

This systematic review and meta-analysis protocol is based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statement. The literature search will involve MEDLINE, EMBASE, Cochrane Library, Web of Science and Scielo for articles published up to July 2019. This search will include randomised controlled trials (RCTs), non-randomised experimental studies and single-arm pre-post studies. Further, the Cochrane Collaboration's tool for RCT studies and the Quality Assessment Tool for Quantitative Studies for non-randomised experimental and single-arm pre-post studies will be used to assess the risk of bias among the studies included in the systematic review. For the meta-analysis, the statistical program STATA V.14 will be used, and standardised mean differences are calculated as the primary outcomes. Subgroup analyses will then be performed based on the characteristics of the interventions and populations included in the studies examined.

ETHICS AND DISSEMINATION

This systematic review protocol is designed to provide updated evidence regarding the effects of physical activity interventions on the Latin American population; such evidence may be useful for institutions responsible for the development of public health policies and for those tasked with implementing such interventions among children and adolescents in Latin America. The results should be disseminated through publication in a peer-reviewed journal. Since the data used in systematic reviews of this type will be extracted exclusively from published studies, approval from an ethics committee will not be required.

Partnering Support Interventions with Bariatric Surgery to Maximize Health Outcomes in Adolescents with Severe Obesity

OBJECTIVE

Rates of adolescents with severe obesity continue to rise worldwide, with concurrent increases in metabolic and bariatric surgery (MBS) uptake. The gap between support (lifestyle, pharmacotherapy) interventions and MBS as treatment options for adolescents has been understudied. This review, couched in a socio-ecological framework, investigates how support interventions for adolescents with severe obesity could be combined or sequenced with MBS to optimize health outcomes.

METHODS

A comprehensive search revealed 36 published articles between 1995 and 2019 that included the combination of support interventions and MBS among adolescents.

RESULTS

There were no studies that specifically reported outcomes or effect sizes for the combination of lifestyle intervention with MBS. Previous studies have reported individual results for either lifestyle intervention or MBS but not for their compound effect.

CONCLUSIONS

As rates of adolescents with severe obesity are on the rise globally, future research should focus on how partnering support interventions with MBS can amplify positive short- and long-term health outcomes and within a socio-ecological framework. Understanding the sequence of these approaches will be of particular importance. High-risk and vulnerable populations such as ethnic minorities who have suffered a disproportionate burden of the obesity epidemic must be included in rigorously tested future trials of combination interventions to maximize health outcomes worldwide.

Does an Age-Specific Treatment Program Augment the Efficacy of a Cognitive-Behavioral Weight Loss Program in Adolescence and Young Adulthood? Results from a Controlled Study

Research on weight-loss interventions in emerging adulthood is warranted. Therefore, a cognitive-behavioral group treatment (CBT), including development-specific topics for adolescents and young adults with obesity (YOUTH), was developed. In a controlled study, we compared the efficacy of this age-specific CBT group intervention to an age-unspecific CBT group delivered across ages in an inpatient setting. The primary outcome was body mass index standard deviation score (BMI-SDS) over the course of one year; secondary outcomes were health-related and disease-specific quality of life (QoL). 266 participants aged 16 to 21 years (65% females) were randomized. Intention-to-treat (ITT) and per-protocol analyses (PPA) were performed. For both group interventions, we observed significant and clinically relevant improvements in BMI-SDS and QoL over the course of time with small to large effect sizes. Contrary to our hypothesis, the age-specific intervention was not superior to the age-unspecific CBT-approach.

Energy balance-related factors associating with adolescent weight loss intent: evidence from the 2017 National Youth Risk Behavior Survey

BACKGROUND

The purpose of this study was to examine specific energy balance-related behaviors (sedentary behaviors, physical activity, and dietary) associating with adolescent weight loss intent using data from the 2017 US Youth Risk Behavior Survey (YRBS).

METHODS

This was a cross-sectional study that employed a multi-stage cluster sampling procedure to obtain a representative sample of US adolescents. The target population consisted of public and private high schoolers from grades 9 through 12. The number of sampled adolescents was 18,324 with 14,765 of the 18,324 sampled students (Mean age = 15.9 (1.3) years) submitting questionnaires with usable data (81% response rate). The outcome was intent to lose weight with specific energy-balance related behaviors examined as predictor variables. A weighted logistic regression model was employed to examine the associations between sedentary behaviors, physical activity, and dietary-related variables with weight loss intent controlling for age, sex, BMI percentile, and race/ethnicity.

RESULTS

Variables associating with adolescent intent to lose weight included 3 or more hours of video game playing (OR = 1.15, 95%CI: 1.01-1.31, p = 0.028), achieving 60 min of physical activity daily (OR = 0.66, 95%CI: 0.59-0.73, p < 0.001), daily breakfast consumption (OR = 0.76, 95%CI: 0.67-0.87, p < 0.001) and weekly salad consumption (OR = 1.30, 95%CI: 1.12-1.52, p = 0.001).

CONCLUSIONS

Meeting physical activity guidelines and regular breakfast consumption associated with lower odds of weight loss intent and video game playing and salad consumption associated with higher odds of weight loss intent in a representative sample of US adolescents. Therefore, there is a discordance between adolescent weight loss intent and the engagement in specific energy balance-related health behaviors, particularly physical activity.

Stability, Continuity, and Bi-Directional Associations of Parental Feeding Practices and Standardized Child Body Mass Index in Children from 2 to 12 Years of Age

(1) Background: Parental feeding practices are related to child body mass index (BMI, kg/m²) and seem to be a consequence rather than cause of child BMI, but research so far is limited. Stability and continuity of feeding practices, probably explaining changes in food intake and child BMI, remain to be poorly examined. (2) Methods: Feeding practices (i.e., restriction, food as reward, pressure to eat, monitoring) assessed via the Child Feeding Questionnaire, child age, standardized BMI (zBMI), and socio-economic status were measured annually at multiple visits (range 2–8) in a population-based longitudinal cohort study of 1512 parents with their children aged 2 to 12 years. Stability, continuity, and bi-directionality of feeding practices and child zBMI were calculated using correlation coefficients, paired t tests, and cross-lagged panels, respectively. (3) Results: Feeding practices and child zBMI showed moderate to high stability. While continuity was high for restriction, minor temporal changes were observed for other feeding practices and child zBMI. Cross-lags indicated that child zBMI predicted restriction, pressure to eat, and monitoring, while food-rewarding predicted child zBMI only minorly. (4) Conclusions: Parents seem to adapt feeding practices to child zBMI with the exception of food-rewarding.

A biopsychosocial approach to processes and pathways in the development of overweight and obesity in childhood: Insights from developmental theory and research

Childhood obesity has reached alarming proportions in many countries. There is consensus that both biological (especially genetic) and environmental (including psychosocial) factors contribute to weight gain and obesity in childhood. Research has identified extensive risk or predictive factors for childhood obesity from both of these domains. There is less consensus about the developmental processes or pathways showing how these risk factors lead to overweigh/obesity (OW/OB) in childhood. We outline a biopsychosocial process model of the development of OW/OB in childhood. The model and associated scholarship from developmental theory and research guide an analysis of research on OW/OB in childhood. The model incorporates biological factors such as genetic predispositions or susceptibility genes, temperament, and homeostatic and allostatic processes with the psychosocial and behavioral factors of parenting, parental feeding practices, child appetitive traits, food liking, food intakes, and energy expenditure. There is an emphasis on bidirectional and transactional processes linking child biology and behavior with psychosocial processes and environment. Insights from developmental theory and research include implications for conceptualization, measurement, research design, and possible multiple pathways to OW/OB. Understanding the developmental processes and pathways involved in childhood OW/OB should contribute to more targeted prevention and intervention strategies in childhood.

Cafeteria diet increased adiposity in comparison to high fat diet in young male rats

Background

Dietary intervention studies in animal models of obesity are crucial to elucidate the mechanistic effects of specific nutrients and diets. Although several models of diet induced obesity have been examined in rodents to assess obesity, there are few studies that have researched influence of different high fat and/or westernized diets. The aim of this study was to compare a high fat diet and a cafeteria diet on obesity related biochemical and physiological parameters in young male rats.

Methods

Five week old Wistar male rats were fed a control chow diet (C), butter-based high fat diet (HF) or cafeteria diet (CAF) for twelve weeks. In HF, 40% of energy came from fat and this ratio was 46% in CAF. CAF composed of highly energetic and palatable human foods along with chow diet. At the end of the feeding protocol all animals were culled using CO₂ asphyxia and cervical dislocation after an overnight fasting.

Results

Total energy and fat intake of CAF was significantly higher than C and HF. CAF was more effective in inducing obesity, as demonstrated by increased weight gain, Lee index, fat depot weights and total body fat in comparison to C and HF. Despite increased adiposity in CAF, plasma glucose, insulin and HOMA-IR levels were similar between the groups. Plasma leptin and cholesterol levels were markedly higher in CAF than C and HF.

Discussion

We have demonstrated that there are differential effects of high fat diet and cafeteria diet upon obesity and obesity-related parameters, with CAF leading to a more pronounced adiposity in comparison to high fat diet in young male rats. Future studies should consider the varied outcomes of different diet induced obesity models and development of a standardized approach in similar research practices.

Outcomes from a Whole-Systems Ayurvedic Medicine and Yoga Therapy Treatment for Obesity Pilot Study

OBJECTIVES

To determine the feasibility and acceptability of an Ayurveda/Yoga intervention for weight loss, using dual-diagnosis inclusion criteria, dual-paradigm outcomes, and a semistandardized protocol with tailoring according to the Ayurvedic constitution/imbalance profile of each participant.

DESIGN

Seventeen participants enrolled in a weekly intervention for 3 months. Outcome measurements were performed at baseline, postintervention, and 3 and 6 months follow-up.

SETTING

The intervention was conducted through the University of Arizona, Department of Family and Community Medicine from April through December 2012.

SUBJECTS

Participants included 2 men and 15 women recruited from the community of Tucson, AZ using flyers and hospital message boards. Seventeen enrolled and 12 participants provided complete follow-up data.

INTERVENTION

Participants met with an Ayurvedic practitioner twice monthly (six times) and followed semistandardized dietary guidelines with individual tailoring to address relevant psychophysiological imbalances obstructing weight loss and a standardized protocol of therapeutic yoga classes three times weekly with recommended home practice of two to four additional sessions.

OUTCOME MEASURES

Primary outcome was weight loss. Other biomedical outcomes included body mass index, body fat percentage, waist and hip circumference, waist to hip ratio, and blood pressure. Unique instruments were designed to collect data on outcomes associated with the Ayurvedic medical paradigm, including dietary changes by food qualities, mood/affect, relationships, and changes in Ayurvedic imbalance profiles.

RESULTS

Participants lost an average of 3.5 kg during the 3-month intervention. Weight loss at 3 and 6 months postintervention increased to an average of 5.6 kg and 5.9 kg, respectively. Participants who lost 3% of their body weight during the 12 week intervention, lost on average an additional 3% during the follow-up period. Psychosocial outcomes also improved. No additional services were provided to participants during the follow-up period.

CONCLUSIONS

A whole-systems Ayurvedic medicine and Yoga therapy approach provides a feasible promising noninvasive low-cost alternative to traditional weight loss interventions with potential added benefits associated with sustainable holistic lifestyle modification and positive psychosocial changes.

The Effect of a Multidisciplinary Lifestyle Intervention on Obesity Status, Body Composition, Physical Fitness, and Cardiometabolic Risk Markers in Children and Adolescents with Obesity

This study aimed to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity, and assess the additional effects of exercise intervention when compared to usual care. Overall, the 103 enrolled participants were ≥85th percentile of age and sex-specific body mass index (BMI). Participants were divided into groups that received 16 weeks of either usual care or exercise intervention. The BMI z-score of the overall completers decreased by about 0.05 after the 16-week intervention (p = 0.02). After the intervention, only the exercise group had a significantly lower BMI z-score than the baseline score by about 0.1 (p = 0.03), but no significant group by time interaction effects were observed. At the 16-week follow-up, significant group by time interaction effects were observed in percentage body fat (%BF) (β = −1.52, 95%CI = −2.58–−0.45), lean body mass (LM) (β = 1.20, 95%CI = 0.12–2.29), diastolic blood pressure (β = −5.24, 95%CI = −9.66–−0.83), high-sensitivity C-reactive protein (β = −1.67, 95%CI = −2.77–−1.01), and wall sit test score (β = 50.74, 95%CI = 32.30–69.18). We developed a moderate-intensity intervention program that can be sustained in the real-world setting and is practically applicable to both moderate and severe obesity. After interventions, the exercise group had lower %BF and cardiometabolic risk markers, and higher LM and leg muscle strength compared to the usual care group.
