RESUMO

Childhood obesity, affecting 29% of 7-9-year-olds across 33 European countries, is a significant public health challenge. Its persistence into adulthood poses grave health risks influenced by genetic, environmental, and socio-economic factors. Belgium introduced a new care pathway in December 2023, based on the Edmonton Obesity Staging System for Pediatrics (EOSS-P), addressing four health domains and staging obesity severity. This pathway operates across three levels: primary care physicians, Paediatric Multidisciplinary Obesity Management Centres (PMOCs), and Centers of Expertise for Paediatric Obesity Management (CEPOs). Each stage of EOSS-P demands tailored interventions. Early stages involve dietary interventions, physical activity promotion, and behavior modifications. As obesity severity progresses, treatments intensify, encompassing psychological support, anti-obesity medications, and, in some cases, bariatric surgery. Throughout these stages, the involvement of multidisciplinary teams is crucial, emphasizing family-based approaches and continuous monitoring. This article provides detailed guidelines for healthcare professionals, delineating interventions and recommendations tailored to each EOSS-P stage. It emphasizes a holistic approach that extends beyond BMI-based diagnosis, promoting personalized care and prompt escalations between care levels, thereby ensuring optimal management of childhood obesity. This comprehensive framework aims to address the complexities of childhood obesity, emphasizing the importance of timely and targeted interventions for better health outcomes.

RESUMO

BACKGROUND: Local authorities in England have an important role in shaping healthy local environments contributing to childhood obesity. This study examined changes in diet and physical activity in primary school children following a three-year, complex, community-based intervention in Golborne ward, the second most deprived ward in London. METHODS: The Go-Golborne intervention aimed to shape the local environment across multiple settings with the engagement of a large number of local government and community stakeholders in a joint approach. Activities focused on six co-created themes to make changes to local environments and reduce sugary snacks and beverage consumption, increase fruit and vegetable intake, promote healthy snacks, increase active play and travel, and reduce screen time. We analysed changes in self-reported diet and physical activity, collected annually between 2016 and 2019, from 1,650 children aged 6-11 years through six local schools, who all received the intervention. We used multilevel, linear and logistic random-slope regression models adjusted for time on study, baseline age, gender, ethnicity, deprivation quintile, school, and baseline weight status. RESULTS: After three years of follow-up, there were reductions in sugar-sweetened beverage consumption (adjusted beta -0·43 occasions/day, 95% CI -0·55 to -0·32), fruit and vegetable consumption (adjusted beta -0.22 portions, 95% CI -0.44 to 0.001) and car travel to and from school (adjusted OR 0·19, 95% CI 0·06 to 0·66), while screen time increased (high versus moderate/low: OR 2·30, 95% CI 1·36 to 3·90). For other behavioural outcomes, there was no statistically significant evidence of changes. CONCLUSION: Local authorities have substantial powers to make positive changes to the obesogenic environment but programmes remain under-evaluated. Results from the ambitious Go-Golborne intervention demonstrated mixed results in health behaviours following programme implementation. These results underline the importance of a coordinated and comprehensive policy response to support changes in wider environmental and social conditions as well as appropriate and holistic evaluations of initiatives to inform local actions on obesogenic environments.

RESUMO

The increasing incidence of obesity in the pediatric population requires attention to its serious complications. It turns out that in addition to typical, well-known metabolic complications, obesity as a systemic disease carries the risk of equally serious, although less obvious, non-metabolic complications, such as cardiovascular diseases, polycystic ovary syndrome, chronic kidney disease, asthma, thyroid dysfunction, immunologic and dermatologic conditions, and mental health problems. They can affect almost all systems of the young body and also leave their mark in adulthood. In addition, obesity also contributes to the exacerbation of existing childhood diseases. As a result, children suffering from obesity may have a reduced quality of life, both physically and mentally, and their life expectancy may be shortened. It also turns out that, in the case of obese pregnant girls, the complications of obesity may also affect their unborn children. Therefore, it is extremely important to take all necessary actions to prevent the growing epidemic of obesity in the pediatric population, as well as to treat existing complications of obesity and detect them at an early stage. In summary, physicians treating a child with a systemic disease such as obesity must adopt a holistic approach to treatment.

RESUMO

This review aims to emphasise the impact of poor nutrition on children's health and psychological well-being, urging those involved in childhood obesity or nutrition services to broaden their intervention approach. Poor nutrition and childhood obesity affect physical and psychological health. The stress of living with obesity further impacts quality of life, well-being and self-esteem. Children living with obesity may experience adverse childhood events and stress, and young people are able to recall the impact of psychosocial issues such as experiencing stigma and discrimination. Food is often a coping mechanism for managing negative emotions, perpetuating cycles of emotional coping and unhealthy eating behaviours. UK guidelines recommend family-based, multi-component weight management interventions for children living with obesity. Interventions mainly target health behaviours and utilise behaviour change techniques attempting to directly improve diet and physical activity as behavioural outcomes. Whilst these interventions may show some improvements in psychological well-being, there is limited consideration or understanding of the underlying mechanisms of action which indirectly influence engagement and the sustainability of the behaviour change. Lack of attention and inclusion of psychosocial variables in intervention implementation may help explain the variable effectiveness reported across childhood obesity interventions. In conclusion, enhancing the effectiveness of childhood obesity interventions requires a broader approach that fully incorporates psychosocial factors. Those responsible for commissioning, designing and implementing these interventions should adopt a holistic approach that addresses psychological and emotional needs while incorporating underlying mechanisms of action. This shift in focus could result in more sustainable and comprehensive treatment for childhood obesity.

RESUMO

PURPOSE: Describe the method for conducting community-engaged research to identify needed changes for an existing evidence-based intervention, and prepare it for implementation in a community setting within the Dan L Duncan Comprehensive Cancer Center catchment area in an effort to achieve more equitable outcomes in diet-related disease risk factors. METHODS: The intervention, Family Eats, was developed over 10 years ago. It works directly with parents of Black/African American 9-12 year old children to create a healthy home food environment to support prevention of obesity and related cancers. Data collection with community stakeholders occurred through a series of  Community Advisory Board (CAB) meetings guided by the Delphi Technique, an iterative approach for gaining group consensus on a topic. RESULTS: Key information on needed changes and potential implementation strategies were identified. Perceived level of engagement among CAB members was high overall and in terms of both quantity and quality. CONCLUSION: The Delphi Technique shows promise as a method for conducting community-engaged research that promotes engagement and identifies key information needed to adapt and implement an existing intervention in a community setting.

RESUMO

BACKGROUND: Growing evidence for the effect of maternal obesity on childhood asthma motivates investigation of mediating pathways. OBJECTIVE: To investigate if childhood body mass index (BMI), gestational weight gain (GWG) and preterm birth mediate the association of maternal obesity on childhood asthma risk. METHODS: We used electronic medical records from mother-child pairs enrolled in Kaiser Permanente Northern California integrated healthcare system. Children were followed from their birth (2005-2014) until at least age 4 (n = 95,723), age 6 (n = 59,230) or age 8 (n = 25,261). Childhood asthma diagnosis at each age was determined using ICD-9/10 codes and medication dispensings. Prepregnancy BMI (underweight [<18.5], normal [18.5-24.9], overweight [25-29.9], obese [≥30] kg/m2 ) were defined using height and weight measurements close to the last menstrual period date. Child's BMI (Centers for Disease Control and Prevention BMI-for-age percentiles: underweight [<5th], normal [5th-85th], overweight [85th-95th], obese [>95th]) were obtained using anthropometric measurements taken the year preceding each follow-up age. GWG (delivery weight-prepregnancy weight) was categorised based on Institutes of Medicine recommendations (inadequate, adequate, excessive). Implementing first causal inference test (CIT) then causal mediator models (to decompose the natural direct and indirect effects), we examined the potential mediating effect of childhood BMI, GWG, and preterm birth on the association between prepregnancy BMI (continuous and categorical) and childhood asthma. RESULTS: Overall, risk of childhood asthma increased as prepregnancy BMI increased (age 4 risk ratio: 1.07, 95% confidence interval: 1.04, 1.09, per 5 kg/m2 increase in BMI; similar for age 6 and 8). CIT identified childhood BMI and preterm birth, but not GWG as potential mediators. Causal mediation models confirmed childhood BMI, but not preterm birth, as having a partial mediating effect. Results were similar for age 6 and 8, and when continuous mediators (instead of binary) were assessed. CONCLUSIONS: Childhood overweight/obesity has a modest mediating effect on the association between prepregnancy BMI and childhood asthma.

RESUMO

Background: Traumatic events that occur in infancy, childhood, and adolescence can be impactful over the course of a lifespan. Adverse childhood experiences (ACEs) are associated with chronic health problems and mental illness, and can negatively impact educational and job opportunities. There is a growing body of evidence about the relationship between ACEs and the risk of childhood obesity. Trauma informed care (TIC) is an approach to patient care both at the clinical and organizational level that is responsive to the impact past trauma can have on an individual. Methods: This clinical review will focus on the impact of toxic stress from trauma on the child through threats to normal physiology, including the manifestation of obesity through energy regulation pathophysiology, followed by a discussion of TIC principles. Available resources and how trauma informed principles can be used in practice are discussed using case study methodology. Results: TIC programs recognize the impact of trauma on both patients and clinicians. TIC implementation includes application of TIC four assumptions and six key principles out-lined by Substance Abuse and Mental Health Services Administration's guidance. Clinicians supported by well-designed systems recognize that disclosure is not the goal of TIC; instead, broad trauma inquiry, proceeding to risk and safety assessment if indicated, and connection to interventions is the focus. Best practice communication allows clinicians to access information without retraumatizing the patient with ongoing repetition of their trauma experience. Conclusion: Combining the pillars of obesity treatment (i.e., nutrition, physical activity, behavior therapy, medical management) with the tenets of TIC (realize, recognize, respond, resist re-traumatization) affords patients holistic, intentional care and family support. The desired outcomes of TIC align with goals of obesity treatment in children, namely improvement of health and quality of life, sense of self (e.g., body image and self-esteem), and prevention of negative health outcomes.

RESUMO

BACKGROUND: Low-income Hispanic families face marked disparities in obesity, but interventions for obesity prevention and treatment have rarely been designed with this population as a focus. Hispanic culture is characterized by Familism, a value that prioritizes familial respect, cooperation, and togetherness. We describe the rationale and design of a trial of the Healthy Living Program (HeLP), a bilingual whole-family behavioral obesity prevention and treatment intervention designed around the value Familism and addressing food insecurity. METHODS/DESIGN: This two-group randomized comparative effectiveness trial will compare the effects of HeLP versus a primary care counseling intervention (Recommended Treatment of Obesity in Primary Care, or RTOP) on decreasing body mass index (BMI; kg/m2) in Hispanic children 2-16 years of age with obesity and preventing BMI increase among siblings without obesity. 164 families per arm will be recruited from primary care practices. Families randomized to HeLP will participate in 12 two-hour sessions, followed by booster sessions. HeLP sessions include family meals and instruction in parenting skills, nutrition, culinary skills, fitness, and mindfulness delivered at community recreation centers by bilingual health educators and athletic trainers. Families randomized to RTOP will be offered individual visits in primary care every 3 months throughout the 18-month follow-up period. Secondary outcomes include changes to objectively measured child fitness, the home environment related to nutrition, physical activity, and media usage, food insecurity, child eating behaviors, quality of life, parent BMI and waist circumference, and implementation outcomes. DISCUSSION: This protocol paper describes the rationale and planned methods for the comparative effectiveness trial. TRIAL REGISTRATION: Clinicaltrials.gov Identifier NCT05041855 (6/13/2023).

RESUMO

Uptake of child weight management (CWM) support is typically low, and services are not available in all areas. Extended brief interventions (EBIs) have been proposed as an affordable way to provide enhanced support, at a level between one-off brief advice and intensive CWM programs. This rapid systematic review sought to synthesize evidence on the efficacy of EBIs for weight management and obesity prevention in children (2-18 years). Embase and Web of Science were searched from January 2012 to January 2022. Nineteen studies, reporting on 17 separate EBIs, were included. The quality of studies was variable, and the EBIs were heterogeneous. The majority of EBIs (n = 14) were based on motivational interviewing. Five of the included studies reported significant improvements in parent or child determinants of health behavior change. However, robust measures of behavioral determinants were rarely used. No studies reported significant positive effects on child weight. No clear patterns in outcomes were identified. There is currently insufficient evidence for EBIs to be adopted as part of CWM services. To improve the evidence base, EBIs that are currently being implemented by local health services, should be evaluated to establish the most effective content, how it should be delivered, and by whom.

RESUMO

BACKGROUND: The anthroposophical philosophy is a holistic educational and lifestyle approach. Limited information exists on the health-promoting behavioral norms and obesity rates among children living anthroposophical vs. conventional lifestyles. AIMS: This study aims to compare the prevalence of childhood obesity, and parents' perceptions of their children's food environment, between anthroposophical and conventional education systems. METHODS: We performed a cross-sectional analysis of the National Anthropometric Measurement Survey for first grade students in Israel, comparing anthroposophical schools with matched conventional schools. Additionally, an online survey was distributed among parents of children in both school systems, assessing children's eating norms and dietary intake. RESULTS: Overweight and obesity rates were higher among students in conventional schools (n = 205,500) compared to anthroposophical schools (n = 2247) (11.2% vs. 9.6%, and 7.8% vs. 4.8%, respectively; Pv < 0.001). Anthroposophical schools were perceived by more parents to have health-promoting curricula, health promoting teacher behavior, and health promoting social dietary norms, while their children's dietary intake was perceived as healthier both in school and in the after-school, social, and familial environment (Pv < 0.001). CONCLUSIONS: Children in anthroposophical education exhibited lower overweight and obesity rates, and engaged in more health-promoting behaviors. Further research is needed to explore the relationship between the anthroposophical lifestyle and childhood obesity, and to identify effective anthroposophical strategies for health promotion among children.

RESUMO

There is an immediate need to optimize cardiovascular (CV) risk management and primary prevention of childhood obesity to timely and more effectively combat the health hazard and socioeconomic burden of CV disease from childhood development to adulthood manifestation. Optimizing screening programs and risk management strategies for obesity-related CV risk in childhood has high potential to change disease trajectories into adulthood. Building on a holistic view on the aetiology of childhood obesity, this document reviews current concepts in primary prevention and risk management strategies by lifestyle interventions. As an additional objective, this scientific statement addresses the high potential for reversibility of CV risk in childhood and comments on the use of modern surrogate markers beyond monitoring weight and body composition. This scientific statement also highlights the clinical importance of quantifying CV risk trajectories and discusses the remaining research gaps and challenges to better promote childhood health in a population-based approach. Finally, this document provides an overview on the lessons to be learned from the presented evidence and identifies key barriers to be targeted by researchers, clinicians, and policymakers to put into practice more effective primary prevention strategies for childhood obesity early in life to combat the burden of CV disease later in life.

RESUMO

PURPOSE: This study was conducted to determine the relationship between child and parents' health behaviors and childhood obesity. In addition, an adaptation of the Turkish version of the Family Health Behavior Scale (FHBS) was performed in this study. DESIGN AND METHODS: This is a descriptive and methodological study. The research sample consisted of 358 parents who have a child between the ages of 5 and 12 studying in one of the seven state schools at the kindergarten, primary, and secondary school levels in Istanbul. Data were collected between February 2022 to May 2022 using the Parent and Child Descriptive Information Form, the Family Nutrition and Physical Activity (FNPA) Screening Tool, and the FHBS. IBM SPSS 25.0 (IBM, Armonk, NY, USA) and SPSS AMOS 21.0 software were used to analyze the data. RESULTS: It was found that the confirmatory factor analysis result of FHBS confirmed the original structure of the scale, and Cronbach's Alpha coefficient was calculated as 0.80. A positive correlation was found between the parents' total scores of FNPA and FHBS (r:0.511, p < 0.001). CONCLUSIONS: It is recommended to evaluate the child and their parents holistically in preventing and managing childhood obesity. School health nurses should plan family-centered interventions to improve health behaviors and carry out these interventions with a multidisciplinary team. Moreover, it has been determined that FHBS is a valid and reliable measurement tool for the Turkish population.

RESUMO

The Healthy Life Trajectories Initiative, an international consortium developed in partnership with the World Health Organization, is addressing childhood obesity from a life-course perspective. It hypothesises that an integrated complex intervention from preconception, through pregnancy, infancy and early childhood, will reduce childhood adiposity and non-communicable disease risk, and improve child development. As part of the Healthy Life Trajectories Initiative in South Africa, the Bukhali randomised controlled trial is being conducted with 18-28-year-old women in Soweto, where young women face numerous challenges to their physical and mental health. The aims of this paper were to describe the intervention development process (including adaptations), intervention components, and process evaluation; and to highlight key lessons learned. Intervention materials have been developed according to the life-course stages: preconception (Bukhali), pregnancy (Bukhali Baby), infancy (Bukhali Nana; birth-2 years), and early childhood (Bukhali Mntwana, 2-5 years). The intervention is delivered by community health workers, and includes the provision of health literacy resources, multi-micronutrient supplementation, in-person health screening, services and referral, nutrition risk support, SMS-reminders and telephonic contacts to assist with behaviour change goals. A key adaption is the incorporation of principles of trauma-information care, given the mental health challenges faced by participants. The Bukhali process evaluation is focussing on context, implementation and mechanisms of impact, using a mixed methods approach. Although the completion of the trial is still a number of years away, the documentation of the intervention development process and process evaluation of the trial can provide lessons for the development, implementation, and evaluation of such complex life-course trials. Supplementary Information: The online version contains supplementary material available at 10.1007/s43477-023-00073-8.

RESUMO

The ketogenic diet is known to be a possible adjuvant treatment in several medical conditions, such as in patients with severe or drug-resistant forms of epilepsy. Its use has recently been increasing among adolescents and young adults due to its supposed weight-loss effect, mediated by lipolysis and lowered insulin levels. However, there are still no precise indications on the possible use of ketogenic diets in pediatric age for weight loss. This approach has also recently been proposed for other types of disorder such as inherited metabolic disorders, Prader-Willi syndrome, and some specific types of cancers. Due to its unbalanced ratio of lipids, carbohydrates and proteins, a clinical evaluation of possible side effects with a strict evaluation of growth and nutritional status is essential in all patients following a long-term restrictive diet such as the ketogenic one. The prophylactic use of micronutrients supplementation should be considered before starting any ketogenic diet. Lastly, while there is sufficient literature on possible short-term side effects of ketogenic diets, their possible long-term impact on growth and nutritional status is not yet fully understood, especially when started in pediatric age.

RESUMO

BACKGROUND: Childhood obesity is a chronic disease with negative physical and psychosocial health consequences. To manage childhood overweight and obesity, integrated care as part of an integrated approach is needed. To realise implementation of this integrated care, practical guidance for policy and practice is needed. The aim of this study is to describe the development of a Dutch national model of integrated care for childhood overweight and obesity and accompanying materials for policy and practice. METHODS: The development of the national model was led by a university-based team in collaboration with eight selected Dutch municipalities who were responsible for the local realisation of the integrated care and with frequent input from other stakeholders. Learning communities were organised to exchange knowledge, experiences and tools between the participating municipalities. RESULTS: The developed national model describes the vision, process, partners and finance of the integrated care. It sets out a structure that provides a basis for local integrated care that should facilitate support and care for children with overweight or obesity and their families. The accompanying materials are divided into materials for policymakers to support local realisation of the integrated care and materials for healthcare professionals to support them in delivering the needed support and care. CONCLUSIONS: The developed national model and accompanying materials can contribute to improvement of support and care for children with overweight or obesity and their families, and thereby help improve the health, quality of life and societal participation of these children. Further implementation of the evidence- and practice-based integrated care while evaluating on the way is needed.

RESUMO

Although puberty is known to influence obesity progression, the molecular mechanisms underlying the role of sexual maturation in obesity-related complications remains largely unexplored. Here, we delve into the impact of puberty on the most relevant pathogenic hallmarks of obesity, namely oxidative stress and inflammation, and their association with trace element blood status. To this end, we studied a well-characterized observational cohort comprising prepubertal (N = 46) and pubertal (N = 48) children with obesity. From all participants, plasma and erythrocyte samples were collected and subjected to metallomics analysis and determination of classical biomarkers of oxidative stress and inflammation. Besides the expected raise of sexual hormones, pubertal children displayed better inflammatory and oxidative control, as reflected by lower levels of C-reactive protein and oxidative damage markers, as well as improved antioxidant defense. This was in turn accompanied by a healthier multielemental profile, with increased levels of essential elements involved in the antioxidant system and metabolic control (metalloproteins containing zinc, molybdenum, selenium, and manganese) and decreased content of potentially deleterious species (total copper, labile free iron). Therefore, our findings suggest that children with obesity have an exacerbated inflammatory and oxidative damage at early ages, which could be ameliorated during pubertal development by the action of trace element-mediated buffering mechanisms.

RESUMO

The International Society of Pediatric and Adolescent Diabetes (ISPAD) recommends metformin (MET) use for metabolic disturbances and hyperglycemia, either in combination with insulin therapy or alone. A caveat of MET therapy has been suggested to be biochemical vitamin B12 deficiency, as seen mainly in studies conducted in adults. In the present case-control study, children and adolescents of different weight status tiers on MET therapy for a median of 17 months formed the cases group (n = 23) and were compared with their peers not taking MET (n = 46). Anthropometry, dietary intake, and blood assays were recorded for both groups. MET group members were older, heavier, and taller compared with the controls, although BMI z-scores did not differ. In parallel, blood phosphorus and alkaline phosphatase (ALP) concentrations were lower in the MET group, whereas MCV, Δ4-androstenedione, and DHEA-S were higher. No differences were observed in the HOMA-IR, SHBG, hemoglobin, HbA1c, vitamin B12, or serum 25(OH)D3 concentrations between groups. Among those on MET, 17.4% exhibited vitamin B12 deficiency, whereas none of the controls had low vitamin B12 concentrations. Participants on MET therapy consumed less energy concerning their requirements, less vitamin B12, more carbohydrates (as a percentage of the energy intake), and fewer fats (including saturated and trans fats) compared with their peers not on MET. None of the children received oral nutrient supplements with vitamin B12. The results suggest that, in children and adolescents on MET therapy, the dietary intake of vitamin B12 is suboptimal, with the median coverage reaching 54% of the age- and sex-specific recommended daily allowance. This low dietary intake, paired with MET, may act synergistically in reducing the circulating vitamin B12 concentrations. Thus, caution is required when prescribing MET in children and adolescents, and replacement is warranted.

RESUMO

Background: Antioxidants have beneficial effects on health. Shrimp oil has Astaxanthin and omega 3 that act as powerful antioxidants and might have anti-inflammatory effects on cardiovascular diseases. This study aims to investigate the effects of shrimp oil supplementation on cardio-metabolic risk factors in overweight and obese children and adolescents. Methods: This randomized, triple-blind, placebo-controlled clinical trial was conducted on 64 overweight and obese participants with 10-18 years of age. They were randomly assigned to receive either 500 mg shrimp oil or identical placebo that contained medium-chain triglycerides once per day for eight weeks. Dietary intake was obtained using food record questionnaire for three days at baseline and at the end of the study. Fasting blood samples were obtained at baseline and after eight weeks of intervention. Results: Overall, 53 participants completed the study; 30 subjects received shrimp oil and 23 subjects received placebo. There were no significant effects of shrimp oil on total cholesterol, triglyceride, HDL-C, LDL-C and blood pressure compared with the placebo group (p>0.05). Shrimp oil had no significant effects on body mass index, waist circumference and hip circumference compared with the placebo group (p>0.05). Conclusions: Supplementation with shrimp oil had no significant effects on improving the anthropometric measures and cardio-metabolic risk factors. Future clinical trials are needed to investigate the beneficial effects of higher doses of shrimp oil on cardio-metabolic risk factors in the pediatric age groups.

RESUMO

In this chapter, we describe a metallomics method based on protein precipitation under non-denaturing conditions and further analysis by inductively coupled plasma mass spectrometry for high-throughput metal speciation in plasma and erythrocyte samples. This methodology enables to study the total multielemental profile of these biological matrices, as well as to quantify the metal fractions conforming the metallometabolome and the metalloproteome. Furthermore, the analytical coverage comprises several essential and toxic metal elements, namely aluminum, arsenic, cadmium, cobalt, chromium, copper, iron, lithium, manganese, molybdenum, nickel, lead, selenium, vanadium, and zinc. Altogether, the metallomics method here proposed represents an excellent approach to comprehensively characterize the metal biodistribution in human peripheral blood, which would enable to decipher the role of metal homeostasis in health and disease, and particularly in childhood obesity.
