Effects of dietary interventions on gut microbiota and related cardiometabolic changes in pediatric obesity: a systematic review and meta-analysis.

BACKGROUND: Gut microbiota imbalances may contribute to obesity, yet whether dietary interventions can modulate the microbiota and improve metabolic health in pediatrics has not been thoroughly reviewed. This systematic review and meta-analysis explores the impact of dietary interventions on the gut microbiota of children and adolescents with overweight or obesity, and its association with cardiometabolic improvements. METHODS: A systematic search of clinical trials in Pubmed, Cochrane and EMBASE was conducted following PRISMA guidelines (PROSPERO n&#xb0;CRD42024505494). Risk of bias was assessed with RoB2 and ROBINS, for randomized and non-randomized intervention studies. RESULTS: Overall, 60 articles were assessed for full-text eligibility, 8 were included, and 4 provided alpha-diversity data for meta-analysis. A total of 200 participants were included (6-16 years). Six studies implemented calorie-restricted diets, one a low free-sugar diet, and one CHILD-1 diet. The meta-analysis revealed a significant increase in Chao1 (48.76 [95%CI 1.81; 95.70]; I2&#x2009;=&#x2009;86.8%, p&#x2009;<&#x2009;0.001) following a balanced calorie-restricted dietary intervention. Although&#xa0;there was heterogeneity in taxa-level changes, several butyrate-producing genera (Clostridium XVIa, Coprococcus, Roseburia, Faecalibacterium, Blautia, Butyricimonas) increased following dietary intervention. CONCLUSIONS: Balanced dietary interventions with calorie-restriction adequate for pediatric age could increase gut microbiota richness and butyrate-producing bacteria abundance. Future trials should clarify diet-driven gut microbiota changes in childhood obesity and related metabolic changes. IMPACT: Balanced calorie restriction diet may increase gut microbiota richness in childhood obesity Butyrate-producer expansion needs long-term dietary intervention Gaps in linking microbiota-metabolism interplay in pediatric obesity.

Plasma inflammatory proteome profiles identify MASLD among children with overweight or obesity.

BACKGROUND & AIMS: Pediatric metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly prevalent among children with overweight or obesity, yet its early diagnosis remains a major clinical challenge. This study aimed to identify circulating inflammatory proteins associated with MASLD and to develop a proteomic risk score (ProScore) to improve diagnostic accuracy. METHODS: In this cross-sectional study of 161 children (median age 8.5&#xa0;years) with overweight or obesity, MASLD was assessed by vibration-controlled transient elastography, with 42 cases identified. Plasma concentrations of 92 inflammation-related proteins were quantified using a high-throughput proximity extension assay. The ProScore was compared with eleven conventional anthropometric/metabolic indices (WHtR, METS-IR, SPISE, PNFI, VAI, LAP, TyG, TyG-ALT, TyG-WC, TyG-WHtR, and TyG-BMI) and a genetic risk score (GRS). Six machine learning algorithms were employed and diagnostic performance was assessed using area under the curve (AUC) with fivefold cross-validation. RESULTS: Fifteen proteins were significantly associated with MASLD. A six-protein panel (FGF-21, CDCP1, CD244, OPG, Flt3L, MCP-1) achieved the highest diagnostic accuracy (AUC&#x2009;=&#x2009;0.84), exceeding that of all conventional indices (AUC&#x2009;=&#x2009;0.65-0.78; all P&#x2009;<&#x2009;0.05). ProScore performance remained robust in school-based validation (AUC&#x2009;=&#x2009;0.83), with no substantial improvement when combined with conventional indices. Diagnostic accuracy was higher in children with lower GRS (AUC&#x2009;=&#x2009;0.92) than in those with higher GRS (AUC&#x2009;=&#x2009;0.80; P&#x2009;=&#x2009;0.003). CONCLUSIONS: A proteomic signature of systemic inflammation provides accurate, non-invasive identification of MASLD in at-risk children, outperforming conventional metabolic and genetic tools, and may have utility in clinical and public health settings.

The Efficacy of Pharmacotherapy Intervention on Anthropometric Outcomes in Survivors of Childhood Brain Tumors: An Updated Systematic Review and Meta-Analysis.

INTRODUCTION: Many survivors of childhood brain tumors face long-term adverse health outcomes like obesity. Uncertainties surround the effect of interventions to manage obesity-related outcomes in survivors of childhood brain tumors. The goal of this updated systematic review and meta-analysis was to provide the best estimate of the treatment efficacy of pharmacotherapy intervention on anthropometric outcomes in this pediatric population. METHODS: We searched CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, PubMed, ClinicalTrials.gov, and ProQuest for articles published from January 1, 2015, to January 31, 2025. A meta-analysis was performed using the generic inverse-variance method in RevMan 5.4. Heterogeneity was assessed using the Cochrane Q test and the I2 statistic. We used the GRADE approach to determine the certainty of evidence. RESULTS: A total of six studies met the inclusion criteria: four newly identified studies published after January 1, 2015 (125 participants), and two from the previously published review (23 participants). The pooled estimate showed no significant change in body mass index z-score after intervention (mean difference&#x2009;=&#x2009;-0.02; 95% CI: -0.06 to 0.02, I2&#x2009;=&#x2009;0%; 4 studies, 94 participants; low certainty of evidence). Similar pooled effects were observed across other outcomes; however, individual studies reported significant changes in some outcomes within the treatment groups after the intervention. CONCLUSION: Pharmacological agents showed no significant change in anthropometric outcomes for survivors of childhood brain tumors. Further trials are needed to assess the efficacy of pharmacological agents and to identify subgroups most likely to benefit.

Effects of Family-Based Intervention for Childhood Obesity on Parental and Offspring Outcomes: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Childhood obesity is a global public health issue with strong familial and intergenerational transmission. However, existing syntheses often overlook the active role of parents and fail to assess outcomes beyond the child. This systematic review and meta-analysis specifically investigate the effects of family-based interventions, which position parents as active co-agents of change, on health outcomes for both children with obesity and their parents. METHODS: A systematic review and meta-analysis were conducted. Six databases were searched for randomized controlled trials (RCTs) targeting children with obesity and at least one family member. Primary outcomes were children's BMI z-score and parental BMI; secondary outcomes included other adiposity measures and dietary behaviors. Outcomes for both children and parents were synthesized. Subgroup analyses were conducted based on intervention characteristics. Risk of bias was assessed using RoB 2, and evidence certainty was evaluated using GRADE. RESULTS: Twenty RCTs with 1740 participants were included in the meta-analysis. The interventions demonstrated a significant reduction in children's BMI z-score. Additional benefits were observed for long-term BMI z-score and percentage of total body fat. The most effective interventions commonly integrate health education, behavioral strategies, and motivational support. Subgroup analyses indicated that interventions positioning parents as active co-participants, rather than mere supporters, yielded larger effects. However, no significant effects were found on parental BMI. CONCLUSION: This study demonstrates that family-based interventions can confer significant benefits for children with obesity. Their success hinges on strategically framing parents as active co-agents and integrating motivational strategies.

Epigenetics and childhood obesity: DNA methylation coordinates environment and gene regulation.

Childhood obesity is a complex disorder which results from the combined contribution of genetics, the environment, and development, which is programmed and coordinated by epigenetic mechanisms. Of them, DNA methylation has emerged as an important molecular interface between environmental inputs and changes in gene expression. In this review, we provide an overview of the role of DNA methylation in childhood obesity during the key developmental stages, from prenatal life and childhood to adolescence. We also highlight the available evidence from candidate genes and genome-wide association studies implicating critical loci involved in energy homeostasis and adipogenesis, where DNA methylation is altered. Further, we also provide an overview of how maternal obesity, nutritional status, and bariatric surgery shape offspring's methylation profiles and contribute to the increased risk of programming obesity across generations. Although aberrant methylation patterns are consistently associated with altered metabolic phenotypes, disentangling causality remains a significant challenge. Herein, we highlight emerging approaches, such as rigorous longitudinal cohorts, epigenetic Mendelian randomization, and CRISPR-based epigenome editing, that are beginning to provide the analytical clarity needed to move beyond association. Finally, we examine the potential of DNA methylation signatures to inform early risk stratification and prevention possibilities. Although yet to be clinically validated, whole-genome methylation profiling is increasingly integrated with systems biology and multi-omics frameworks, making the identification of robust, clinically actionable markers more promising. A more precise understanding of how epigenetic processes shape susceptibility to childhood obesity could ultimately support strategies capable of altering lifelong metabolic trajectories.

Determinants of Meal Satisfaction and Their Association With Childhood Obesity: A Systematic Review.

Meal satisfaction is considered a multidimensional concept that includes sensory enjoyment, cognitive, emotional, and physiological components and relates to contentment with the meal experience as a whole. However, its relevance to eating behavior and body weight remains unclear, especially in children. The present review investigated the potential relationship between meal satisfaction-related constructs and childhood obesity, and whether this relation is shaped by individual factors and the external environment. Seventeen eligible studies from 350 records published between 2008 and 2024 were included. No study directly assessed meal satisfaction; instead, proxy measures were used. Food enjoyment emerged as the proxy most consistently associated with BMI, often clustering with higher food responsiveness, lower satiety responsiveness, and emotional overeating. Parental feeding practices, especially pressure to eat, significantly contributed to variation in children's eating behavior and were associated with lower food enjoyment. Overall, meal satisfaction could be a key aspect to consider in childhood obesity prevention programs. However, to date, the available evidence is heterogeneous and predominantly observational. Future longitudinal and intervention studies are needed, alongside child-appropriate instruments to objectively quantify food satisfaction in children. Research that helps understand the role of contextual eating factors on children's meal satisfaction and eating behavior is also warranted.

[Current aspects and prospects of preventive pediatrics in France].

Preventive medicine perhaps achieved its earliest and most complete successes in the field of pediatrics. Work on the problems of main concern in the last third of the century has reached a stage where preventive medicine has virtually mastered those of nutrition and infection in our countries. The current problems are malformation, accidents, and suicide, and this has meant a major shift of interest for preventive activity. In some fields, prevention-detection of neonatal affections takes place in the prenatal period: here, the pediatrician joins hands with the geneticist and the obstetrician. In other fields, such as accident prevention, the pediatrician's role is of particular importance to the authorities, industry, and the family. Finally, and this is new, the pediatrician is responsible for the prevention of diseases occurring in the adult. His role in this was a matter of course in nutritional diseases such as malnutrition and rickets, and in infections such as tuberculosis. It is assuming increasing importance in the detection and prevention of certain risk factors and common affections of the adult such as obesity, hypertension and atheroma.

American Academy of Pediatrics. Nutrition Committee of the Canadian Paediatric Society and the Committee on Nutrition of the American Academy of Pediatrics. Breast-feeding. A commentary in celebration of the International Year of the Child, 1979.

1. Full-term newborn infants should be breastfed, except if there are specific contraindications or when breast-feeding is unsuccessful. 2. Education about breast-feeding should be provided in schools for all children, and better education about breast-feeding and infant nutrition should be provided in the curriculum of physicians and nurses. Information about breast-feeding should also be presented in public communications media. 3. Prenatal instruction should include both theoretical and practical information about breast-feeding. 4. Attitudes and practices in prenatal clinics and in maternity wards should encourage a climate which favors breast-feeding. The staff should include nurses and other personnel who are not only favorably disposed toward breast-feeding but also knowledgeable and skilled in the art. 5. Consultation between maternity services and agencies committed to breast-feeding should be strengthened. 6. Studies should be conducted on the feasibility of breast-feeding infants at day nurseries adjacent to places of work subsequent to an appropriate leave of absence following the birth of an infant.

Effectiveness of a digi-physical tool and working method for paediatric obesity treatment in Abu Dhabi: a non-inferiority intervention study using an external historical comparator.

BACKGROUND: Effective paediatric obesity treatment requires high intensity, scalable interventions. A digi-physical tool for paediatric obesity treatment has shown positive results in Stockholm, Sweden. This study evaluates whether the same treatment method is effective in a different cultural setting. METHODS: This non-inferiority intervention study, using an external historical comparator, included 60 consecutively recruited children aged 6-15.9 years with obesity who initiated treatment at Sheikh Shakhbout Medical City in Abu Dhabi between June and December 2023. Patients were treated with Evira, a digi-physical tool and working method enabling high intensity individualized care, real-time monitoring, and interactive patient-clinician communication. The primary outcome was BMI z-score change at 26 weeks. Non-inferiority was assessed using a predefined margin of 0.10 BMI z-score, with outcomes compared to a prior published trial in Stockholm (n&#x2009;=&#x2009;107). RESULTS: A total of 112 children were included in the analysis (Abu Dhabi cohort, n&#x2009;=&#x2009;35; Stockholm cohort, n&#x2009;=&#x2009;77). The adjusted mean change in BMI z-score was -&#x2009;0.20 (95% CI: -&#x2009;0.28, -&#x2009;0.12) in the Abu Dhabi cohort and -&#x2009;0.20 (- 0.26, -&#x2009;0.14) in the Stockholm cohort (p&#x2009;=&#x2009;0.88). Non-inferiority was confirmed, (predefined margin 0.10 was not exceeded). A clinically significant BMI z-score reduction (&#x2265;&#x2009;0.20 units) was achieved by 45.7% of participants in Abu Dhabi and 36.4% in Stockholm (p&#x2009;=&#x2009;0.35). Non-retention rates at 26 weeks were 41.7% vs. 28.0%, respectively (p&#x2009;=&#x2009;0.07). CONCLUSIONS: The findings provide promising evidence that treatment outcomes achieved with the digi-physical treatment tool were comparable in the Abu Dhabi and Stockholm cohorts, supporting its feasibility in a second cultural and healthcare setting.

Deimplementation of inappropriate feeding practices in early care and education: a Hybrid Type 3 cluster-randomized trial.

BACKGROUND: The science of deimplementation-reducing harmful or ineffective practices-has focused almost exclusively on clinical prescribing, with no studies conducted in community or educational settings. Early care and education (ECE) settings offer a strategic venue for shaping eating behaviors, with children consuming up to 500 meals annually in these environments. However, ECE educators routinely use feeding practices that undermine self-regulation, including pressuring children to eat, rushing mealtimes, and offering food as reward. These practices contribute to food aversions, diminished self-regulation, and obesity risk. METHODS: We will conduct a Hybrid Type 3 cluster-randomized trial evaluating a co-designed deimplementation strategy package (WISE Words) across 88 ECE sites in Arkansas and Louisiana. Sites will be randomized 1:1 to WISE Words or usual practice, with usual practice sites receiving the intervention after two years (waitlist design). WISE Words includes six strategies: dynamic training using improvisation methods, peer learning collaboratives with goal setting, external facilitation, audit and feedback, environmental reminders, and tailored educational materials. The primary outcome is de-adoption of inappropriate feeding practices measured via direct mealtime observation (Table Talk). Secondary outcomes include adoption of evidence-based practices, acceptability, appropriateness, and sustainability at 12- and 24-months post-intervention. Child outcomes include Body Mass Index, skin carotenoid levels (Veggie Meter) willingness to try new foods (observed) and food neophobia (teacher and caregiver report). An explanatory sequential mixed methods design will test mechanisms of change derived from the Implementation Trust Building Theory of Change examining whether trust mediates strategy effects on outcomes. DISCUSSION: This trial extends deimplementation science into community settings by targeting culturally embedded behavioral practices rather than clinical prescribing behaviors. Results will inform approaches to shifting entrenched practices in ECE and similar settings while testing trust as a deimplementation mechanism. Sustainability assessments will address a notable gap, as few studies have examined whether deimplementation effects persist. TRIAL REGISTRATION: NCT07101321, July 20, 2025.

The paediatrician's responsibility for the prevention of coronary heart disease.

A strong case exists in favour of encouraging children not to smoke, to be reasonably physically active and to eat in moderation to avoid obesity. The principal role of the paediatrician is in the education of health personnel who are in a position to influence children and their families to adopt these measures. Paediatricians will also be involved with children at special risk of ischaemic heart disease. They have a responsibility to promote reasearch to determine the efficacy of these measures in the prevention of coronary heart disease.
