The Impact of Chronic Stress Related to COVID-19 on Eating Behaviors and the Risk of Obesity in Children and Adolescents.

During the COVID-19 pandemic, an increase in the incidence of overweight and obesity in children was observed. It appears that unhealthy food choices, an unbalanced diet, and a sedentary lifestyle, as well as experiencing stress related to the pandemic, may be contributing to this disturbing trend. Chronic stress is a significant factor contributing to eating disorders and obesity in youngsters, involving medical, molecular, and psychological elements. Individuals under chronic stress often focus on appearance and weight, leading to negative body image and disrupted relationships with food, resulting in unhealthy eating behaviors. Chronic stress also impacts hormonal balance, reducing the satiety hormone leptin and elevating the appetite-stimulating hormone ghrelin, fostering increased hunger and uncontrolled snacking. Two systems, the hypothalamic-pituitary-adrenal axis and the sympathetic system with the adrenal medulla, are activated in response to stress, causing impaired secretion of noradrenaline and cortisol. Stress-related obesity mechanisms encompass oxidative stress, neuroinflammation, insulin resistance, and neurohormonal and neurotransmission disorders. Stress induces insulin resistance, elevating obesity risk by disrupting blood sugar regulation and fat storage. Stress also affects the gut microbiome, potentially influencing chronic inflammation and metabolic processes linked to obesity. In conclusion, chronic stress is a multifaceted risk factor for eating disorders and obesity in children, necessitating a comprehensive understanding of effective preventive and intervention strategies amid the escalating prevalence of childhood overweight and obesity.

Childhood Mediterranean Diet Adherence Is Associated with Lower Prevalence of Childhood Obesity, Specific Sociodemographic, and Lifestyle Factors: A Cross-Sectional Study in Pre-School Children.

The Mediterranean diet (MD) has been related with a decreased probability of overweight/obesity as well as central obesity at all stages of the human life, decreasing the risk of diverse disease states and improving quality of life. Over the last few years, the prevalence of childhood overweight/obesity and especially abdominal obesity has highly increased worldwide, being associated with a higher likelihood of overweight/obesity as well as central obesity at the next stages of the life during adulthood. The purpose of the present study was to explore the relationship of MD compliance with sociodemographic, anthropometry and lifestyle features in pre-school children aged 2-5 years old. This is a cross-sectional study, which includes 5188 pre-school children from diverse regions of Greece. Relevant questionnaires were applied to evaluate the sociodemographic features of the enrolled children. Anthropometric parameters were measured by relevant techniques. Qualified questionnaires were utilized for assessing several lifestyle factors such as physical activity, quality of life, breastfeeding practices, MD adherence, as well as the prevalence of childhood asthma and diabetes mellitus type I. Of the enrolled children, 41.7% showed low MD compliance and 36.4% of them indicated moderated compliance, while only 21.9% of them showed a high MD adherence. Overweight/obesity was noted in 24.2% of the assigned children, while abdominal obesity was noticed in 18.2% of them. Higher MD compliance was related with an elevated prevalence of sex (boys, p = 0.0005), Greek nationality (p = 0.0088), rural type of residence (p = 0.0099), childhood overweight/obesity (p < 0.0001) and abdominal obesity (p < 0.0001), lower childbirth weight (p < 0.0001), increased physical activity (p = 0.0041), improved quality of life (p = 0.0008), exclusive breastfeeding (p < 0.0001), childhood asthma (p = 0.0001) and diabetes mellitus type 1 (p = 0.0002). A higher MD adherence is associated with specific sociodemographic, better anthropometric, and beneficial lifestyle factors in pre-school children. However, MD compliance remains low or moderate in the vast majority of children aged 2-5 years old. Thus, future public strategies and policies should be performed to inform parents of the potential beneficial effects of MD against obesity and related chronic diseases at the next stage of their children's lives.

Co-Design of a Reusable Learning Object (RLO) to Address Caregiver Responsive Infant Feeding Behaviours (CRIB) to Prevent Childhood Obesity: A Mixed-Method Protocol.

Responsive infant feeding is a key strategy for childhood obesity prevention. Responsive feeding involves caregivers responding to infant hunger and satiety cues in a timely and developmentally appropriate manner. There is a dearth of evidence-based information and guidance for caregivers on how to responsively feed their infants. The aim of this research is to co-design a Reusable Learning Object (RLO) and guidance infographic to improve caregiver awareness, understanding and use of responsive infant feeding behaviours. The Capability, Opportunity, Motivation and Behaviour (COM-B) model of behaviour change and the Aim, Storyboarding, Populate specification, Implement media, Review and release prototype, and Evaluate (ASPIRE) approach for digital intervention co-design will be utilised. Four co-design workshops with caregivers of infants and healthcare professionals (HCPs) will determine priority RLO content. Content analysis will enable RLO development and process reporting. Formative and summative surveys will be conducted to evaluate the usability of the RLO, its impact on caregivers and its potential implementation into NHS care pathways. The output will be a RLO on responsive feeding for caregivers and an infographic for HCPs/support workers which will contribute to a future obesity prevention intervention. The findings will be disseminated to stakeholders and submitted for publication in a peer-reviewed journal.

Perspectives on healthy eating practices and acceptance of WIC-approved foods among parents of young children enrolled in WIC.

The prevalence of childhood obesity remains high in the United States, particularly among children living in low-income households. Diet quality plays an important role in obesity prevention, particularly among mothers as they serve as role models. Those served by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) receive nutrient-rich foods aimed at increasing diet quality, yet redemption is low. Digital interventions targeting WIC parents show potential for behavior change and could be used for childhood obesity prevention. This study describes the formative research conducted to understand perspectives on healthy eating practices, acceptance of WIC-approved foods, and preferences for the use of digital tools to improve the purchasing and consumption of WIC-approved foods to improve diet quality. In-depth interviews were conducted with 13 WIC parents and caregivers. A variety of definitions for and misconceptions about healthy eating exist among WIC caregivers. Most purchased foods were fruits, vegetables, milk, cheese, and eggs and the least purchased foods were yogurt and peanut butter. The biggest facilitator for purchasing WIC-approved foods was the preference of children and caregivers, whereas the biggest barrier was children's picky eating behaviors. Most caregivers reported using their phone to get nutrition information. Most caregivers reported their interest in receiving weekly text messages and indicated preferences about receiving recipes. A text messaging program that includes sending weekly messages, recipes, and nutrition tips is hypothesized to improve diet quality and increase redemption of WIC-approved foods.

Parental Accuracy of Reporting Child Sleep Duration: Examining Sleep and Childhood Obesity in Midwestern Latinx Youth

This study examined the relationship between the accuracy of parental reporting of children’s sleep duration compared to objectively measured child sleep and tested whether any discrepancies were related to childhood obesity prevalence in a sample of Latinx families ( N = 119). A paired sample t-test revealed that parents significantly overestimated their child’s sleep duration by 1.33 hours, t(86) = 6.69, p &lt; .001. Using a one-way ANOVA, no significant differences were found in children’s BMI percentile when grouped by the parent’s accuracy of their child’s sleep duration F(3, 83) = .76, p = .52. A potential, although non-significant, trend regarding parent accuracy and child BMI may merit further examination. Future research should seek to determine if the discrepancy in parent reported child sleep duration is indeed linked with increased child BMI and if this knowledge could be used in targeted intervention efforts to reduce childhood obesity.

Validation of the Comprehensive Feeding Practices Questionnaire (CFPQ) with Portuguese Caregivers of 2-to-8-Year-Olds.

Recent findings have demonstrated an increase in the prevalence of childhood obesity and overweight in Portugal, urging the need to study modifiable risk factors such as parental feeding practices. The Comprehensive Feeding Practices Questionnaire (CFPQ) is an important self-report measure assessing a broad range of responsive and non-responsive feeding practices. However, the CFPQ has not yet been validated in Portugal. Therefore, the present study aimed to test the validity of this measure with Portuguese parents of 2-to-8-year-old children. A sample of 409 parents completed a Portuguese-adapted version of the CFPQ and the already validated Child Feeding Questionnaire (CFQ). Confirmatory factor analysis (CFA), exploratory factor analysis (EFA), and psychometric analysis were conducted. CFA demonstrated the original 12-factor structure did not fit the sample. EFA identified an eight-factor structure comprising 29 items: Monitoring, Modeling, Environment, Involvement, Emotion Regulation, Restriction for Weight Control, Restriction for Health, and Pressure. Findings suggest that parental feeding practices are sensitive to parents' background cultures and children's developmental period.

Effects of a Math-Integrated Afterschool Physical Activity Program: A Case Study

This case study aims to evaluate the impact of an afterschool physical activity (PA) program integrated with mathematics on elementary school students’ Body Mass Index (BMI), fitness levels, and comprehension of geometry concepts–a recommended strategy for preventing child obesity. Utilizing descriptive statistics and t-tests, the study analyzes pre- and post-geometry assessments and FITNESSGRAM® assessments. Despite no significant weight change, the findings reveal improved cognitive understanding of geometry concepts and enhanced fitness levels. This research contributes valuable evidence supporting the positive effects of integrating PA into math learning environments, particularly benefiting low socioeconomic status (SES) and underrepresented children, addressing the decline in both physical activity and math performance during childhood.

Childhood Obesity: Insight into Kidney Involvement.

This review examines the impact of childhood obesity on the kidney from an epidemiological, pathogenetic, clinical, and pathological perspective, with the aim of providing pediatricians and nephrologists with the most current data on this topic. The prevalence of childhood obesity and chronic kidney disease (CKD) is steadily increasing worldwide, reaching epidemic proportions. While the impact of obesity in children with CKD is less pronounced than in adults, recent studies suggest a similar trend in the child population. This is likely due to the significant association between obesity and the two leading causes of end-stage renal disease (ESRD): diabetes mellitus (DM) and hypertension. Obesity is a complex, systemic disease that reflects interactions between environmental and genetic factors. A key mechanism of kidney damage is related to metabolic syndrome and insulin resistance. Therefore, we can speculate about an adipose tissue-kidney axis in which neurohormonal and immunological mechanisms exacerbate complications resulting from obesity. Adipose tissue, now recognized as an endocrine organ, secretes cytokines called adipokines that may induce adaptive or maladaptive responses in renal cells, leading to kidney fibrosis. The impact of obesity on kidney transplant-related outcomes for both donors and recipients is also significant, making stringent preventive measures critical in the pre- and post-transplant phases. The challenge lies in identifying renal involvement as early as possible, as it is often completely asymptomatic and not detectable through common markers of kidney function. Ongoing research into innovative technologies, such as proteomics and metabolomics, aims to identify new biomarkers and is constantly evolving. Many aspects of pediatric disease progression in the population of children with obesity still require clarification. However, the latest scientific evidence in the field of nephrology offers glimpses into various new perspectives, such as genetic factors, comorbidities, and novel biomarkers. Investigating these aspects early could potentially improve the prognosis of these young patients through new diagnostic and therapeutic strategies. Hence, the aim of this review is to provide a comprehensive exploration of the pathogenetic mechanisms and prevalent pathological patterns of kidney damage observed in children with obesity.

Changes in dietary habits and BMI z-score after a 6-month non-randomized cluster-controlled trial among 6-12 years old overweight and obese Norwegian children.

Effective prevention programs to address the high prevalence of childhood overweight and obesity and the concomitant health consequences have been warranted. To improve dietary habits and weight status among Norwegian children with overweight/obesity in the primary care setting. A 6-month non-randomized cluster-controlled intervention among 137 children, aged 6-12 years, with overweight/obesity and their parents. Intervention and control groups were recruited by public health nurses and followed-up by 12 Healthy Life Centers across Norway. The intervention group received individual family counseling and participated in nutrition courses and physical activity groups. A frequency questionnaire assessing sociodemographic characteristics and dietary habits was completed by the parents. Trained public health nurses measured height and weight using standardized methods to calculate body mass index (BMI) and BMI z-scores. The intervention resulted in an increased odds of consuming evening meals (OR: 3.42), a decreased availability of salty snacks (β = -0.17), a decreased intake of salty snacks (-0.18), an increased consumption of water (β = 0.20), and a decreased estimated total intake of energy (β = -0.17), carbohydrates (β = -0.17), mono- and disaccharides (β = -0.21), sucrose (β = -0.24), and saturated fatty acids (β = -0.17). The intervention directly predicted lower BMI z-score (β = -0.17), and post-treatment levels of energy (β = -0.65), saturated fat (β = 0.43), and total carbohydrates (β = 0.41) were directly linked to BMI z-score after intervention. Age and sex were indirectly associated with BMI after intervention through energy and saturated fat intake. The intervention had a beneficial impact on nutrient intake and weight status among children with overweight/obesity. These findings provide support for implementing complex intervention programs tailored to local primary care settings. Clinicaltrials.gov, NCT02290171. Registered 13.

Effects of accelerometer-based sedentary time and physical activity on DEXA-measured fat mass in 6059 children

Globally, childhood obesity is on the rise and the effect of objectively measured movement behaviour on body composition remains unclear. Longitudinal and causal mediation relationships of accelerometer-based sedentary time (ST), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) with dual-energy X-ray absorptiometry-measured fat mass were examined in 6059 children aged 11 years followed-up until age 24 years from the Avon Longitudinal Study of Parents and Children (ALSPAC), UK birth cohort. Over 13-year follow-up, each minute/day of ST was associated with 1.3 g increase in fat mass. However, each minute/day of LPA was associated with 3.6 g decrease in fat mass and each minute/day of MVPA was associated with 1.3 g decrease in fat mass. Persistently accruing ≥60 min/day of MVPA was associated with 2.8 g decrease in fat mass per each minute/day of MVPA, partly mediated by decrease insulin and low-density lipoprotein cholesterol. LPA elicited similar and potentially stronger fat mass-lowering effect than MVPA and thus may be targeted in obesity and ST prevention in children and adolescents, who are unable or unwilling to exercise.

Regional Variations in Pediatric Metabolic and Bariatric Surgeon Availability: A Call for Action

IntroductionObesity is a significant public health concern in children. The American Academy of Pediatrics recommends the use of metabolic and bariatric surgery (MBS) in children with severe obesity, however; MBS remains underutilized in part due to lack of access. This study aims to characterize the prevalence of pediatric obesity and compare this to regional pediatric MBS provider availability. MethodsState-specific prevalence rates of childhood obesity in children aged 10-17 were obtained from the National Survey of Children's Health. The member directory provided by the American Society for Metabolic and Bariatric Surgeons was used to identify all pediatric MBS providers and used to calculate the prevalence of MBS providers by state. ResultsThe five states with the highest prevalence rates of childhood obesity were Kentucky, Mississippi, Louisiana, West Virginia, and Alabama. The five states with the highest prevalence (per 100,000 children with obesity) of MBS providers doing pediatric cases were North Dakota, New Jersey, Kansas, New York, and Utah. Notably, there was a negative correlation between the states with the lowest prevalence of pediatric MBS providers and states with the highest prevalence of childhood obesity (r −0.40, ∗P = 0.002). ConclusionsOur study demonstrates significant state-to-state variation in the prevalence of pediatric obesity and MBS provider availability by state as a proxy for access to surgical care for pediatric obesity. Further work to establish accessible multidisciplinary pediatric weight loss centers is needed to ensure that children and adolescents with obesity receive thorough evaluation and have access to MBS.

Developing a Policy for Healthy Schools Food: A Plan of Action

Background and Objectives: Childhood obesity is a pressing global health concern, particularly in low- and middle-income countries like Palestine. This study aims to address the prevalence of childhood obesity in Palestine and its association with the school food environment. The objective is to propose and advocate for the implementation of a "healthy schools' food policy" to promote the consumption of nutritious food while prohibiting the sale of unhealthy items. Methods: A comprehensive analysis of the sociocultural, economic, political, ethical, and legal contexts surrounding childhood obesity in Palestine was conducted. This included a review of existing studies, stakeholder analyses, and an evaluation of policy alternatives. A legislative strategy was developed to guide the implementation of the proposed policy. Results: The study identified the widespread prevalence of childhood obesity in Palestine, with contributing factors rooted in sociocultural, economic, and political contexts. The analysis of policy alternatives revealed that establishing and enforcing a written protocol for "Food and Beverage Services" in schools emerged as the most effective option. This policy approach received the highest score in terms of effectiveness, access and fairness, cost-effectiveness, and administrative and political feasibility. Conclusion: The findings highlight the urgent need for policy interventions to address childhood obesity in Palestine. The proposed "healthy schools' food policy" offers a promising avenue to promote nutritious food consumption while curbing the availability of unhealthy options. Collaborative efforts involving stakeholders, including schools, the Ministry of Education, healthcare professionals, parents, and the community, are crucial for successful policy implementation. Regular evaluations and community feedback will be essential to monitor the policy's impact and make necessary adjustments. This study underscores the significance of prioritizing children's health within the broader context of societal well-being.

Prevention of childhood overweight and obesity in Mongolia, the Philippines and Vietnam: identifying priority actions.

Low- and middle-income countries are increasingly faced with a triple burden of malnutrition: endemic underweight, micronutrient deficiencies and rising prevalence of overweight. This study aimed to address existing knowledge gaps and to identify priority policy options in Mongolia, the Philippines and Vietnam. A landscape analysis approach was adopted using methods set out in a UNICEF global toolkit. Quantitative and qualitative data were compiled from a range of global and national sources on childhood overweight and obesity, risk factors and policy responses. Key informant interviews and validation workshops were undertaken with key food and nutrition stakeholders from government and non-government organizations to identify priority policy options for the prevention of overweight and obesity among children. Overweight and obesity among children are increasing in all three countries. Associated risk factors are related to maternal nutrition, birthweight, breastfeeding, as well as diets and physical activity shaped by increasingly obesogenic environments. Key informants identified undefined policy approaches, poor community understanding and food and beverage industry influence as barriers to addressing overweight and obesity. Key policy priorities include restricting the marketing of unhealthy food and beverages, unhealthy food and beverage taxation, introduction of front-of-pack nutrition labels and improving school nutrition environments. Mongolia, the Philippines and Vietnam are all facing an increasing burden of childhood overweight and obesity. Despite differing national contexts, similar environmental factors are driving this rise. A suite of evidence-based policies can effectively be introduced to address obesogenic environments.

The return on investment for the prevention and treatment of childhood and adolescent overweight and obesity in China: a modelling study

The rapid increase in child and adolescent overweight and obesity (OAO) in China has a significant health and economic impact. This study undertook an investment case analysis to evaluate the health and economic impacts of child and adolescent OAO in China and the potential health and economic returns from implementing specific policies and interventions. The analysis estimates the reduction in mortality and morbidity from implementing a set of evidence-based interventions across China between 2025 and 2092 using a deterministic Markov cohort model. Modelled interventions were identified by literature review and expert recommendation and include fiscal and regulatory policies, eHealth breastfeeding promotion, school-based interventions, and nutritional counselling by physicians. The study applies a societal costing perspective to model the economic impact on healthcare cost savings, wages, and productivity during adulthood. By projecting and comparing the costs between a status quo scenario and an intervention scenario, the study estimates the return on investment (ROI) for interventions separately and in combination. Without intervention China will experience 3.3 billion disability-adjusted life years (DALYs) due its current levels of child and adolescent OAO and a lifetime economic impact of CNY 218 trillion (USD 31.6 trillion), or a lifetime CNY 2.5 million loss per affected child or adolescent (USD 350 thousand). National implementation of all five interventions would avert 179.4 million DALYs and result in CNY 13.1 trillion of benefits over the model cohort's lifetime. Implementing fiscal and regulatory policies had the strongest ROI, with benefits accruing at least 10 years after implementation. Scaling up China's current school-based interventions offers China significant health and economic gains, however, the ROI is lower than other modelled interventions. Effective prevention and treatment of child and adolescent OAO is critical to China's health and economic development. Multiple interventions offer a comprehensive approach to address the various factors that increase risk of child and adolescent OAO. Nonetheless, fiscal and regulatory policies offer the strongest health and economic gains. Funding was provided by UNICEF China.

Caregiver Influences on Eating Behaviors in Children: An Opportunity for Preventing Obesity.

This review seeks to define caregiver practices that impact childhood eating behaviors and identify ways to utilize these relationships to prevent childhood obesity. Childhood obesity, which correlates with adult obesity and increased cardiovascular risk, is increasing in prevalence and severity. Caregivers play a significant role in shaping a child's eating behaviors and their predisposition to obesity. Maternal influences during pregnancy and infancy impact a child's future food preferences. Caregiver feeding styles (authoritarian, authoritative, indulgent, and uninvolved) are associated with distinct effects on children's eating behaviors and self-regulation. Authoritative feeding styles promote child autonomy while setting boundaries in the feeding environment. Early caregiver education and coaching regarding nutrition and feeding practices is beneficial to establishing healthy eating behaviors for children.Various caregivers, including parents, grandparents, siblings, teachers, and others, influence a child's eating habits at different stages of development. These caregivers can both positively and negatively impact a child's diet. Comprehensive interventions involving these various caregivers to promote healthy eating practices in children is ideal. Such interventions should be sensitive to cultural and environmental factors. Childhood obesity is a complex issue with long-term health effects. Early intervention using comprehensive approaches including all caregivers, community support, and public policies to address the social determinants of health will be beneficial. Future research should focus on valid outcome measures and equitable interventions that encompass all aspects of a child's life.

Which outcome measurement instruments are used to measure core infant feeding outcomes in children up to 1 year of age? A scoping review protocol

Background How, what, and when infants are fed plays a role in the aetiology of childhood obesity. Heterogeneity in how infant feeding outcomes are measured in trials of interventions to prevent childhood obesity limits evidence syntheses and understanding of intervention effectiveness. An infant feeding core outcome set (COS) was previously developed to standardised outcome measurement and reporting. The COS represents what to measure; determining how best to measure these outcomes is the next essential step to improve intervention evaluations. The aim of this scoping review is therefore to identify what outcome measurement instruments have been used in trials, and how they have been used, to measure the core infant feeding outcomes. Methods A scoping review will be conducted. MEDLINE, EMBASE, CINAHL, PsychINFO, the Cochrane Central Register of Controlled Trials, OpenGrey and GreyNet will be searched from inception. Papers are eligible for inclusion if they report trials involving primary data collection that measure and report at least one core infant feeding outcome in infants ≤one year of age. Following searching and screening, eligible studies will be categorised into the following four overarching categories for data extraction, synthesis and write-up: caregiver-related outcomes; diet-related outcomes; feeding environment outcomes; child weight outcomes. Data will be narratively described and presented in tabular format, with findings presented in four separate review papers delineated by the four overarching categories. Discussion This scoping review forms part of the Standardised measurement for Childhood Obesity Prevention (SCOPE) study (www.eiascope.com). Evidence from this scoping review on what measurement instruments are used, and how they are used, represents an essential first step in developing recommendations and guidance about how best to measure core infant feeding outcomes for childhood obesity prevention. This can improve evidence syntheses and understanding of what infant feeding interventions are most effective for childhood obesity prevention.

Perinatal outcomes in women with class IV obesity compared to women in the normal or overweight body mass index categories: A population-based cohort study in Qatar.

The prevalence of childhood and adult obesity is rising exponentially worldwide. Class IV obesity (body mass index, BMI ≥50kg/m2) is associated with a higher risk of adverse perinatal outcomes. This study compared these outcomes between women with class IV obesity and women in the normal or overweight categories during pregnancy. A retrospective cohort study was performed in Qatar, including women having singleton live births beyond 24weeks of gestation, classified into two class IV obesity and normal/overweight (BMI between 18.5 and 30.0kg/m2). The outcome measures included the mode of delivery, development of gestational diabetes and hypertension, fetal macrosomia, small for date baby, preterm birth and neonatal morbidity. Adjusted odds ratios (aOR) with 95% confidence intervals (95% CI) were determined using multivariable logistic regression models. A total of 247 women with class IV obesity were compared with 6797 normal/overweight women. Adjusted analysis showed that women with class IV obesity had 3.2 times higher odds of cesarean delivery (aOR: 3.19, CI: 2.26-4.50), 3.4 times higher odds of gestational diabetes (aOR: 3.39, CI: 2.55-4.50), 4.2 times higher odds of gestational hypertension (aOR: 4.18, CI: 2.45-7.13) and neonatal morbidity (aOR: 4.27, CI: 3.01-6.05), and 6.5 times higher odds of macrosomia (aOR 6.48, CI 4.22-9.99). Class IV obesity is associated with more adverse perinatal outcomes compared with the normal or overweight BMI categories. The study results emphasized the need for specialized antenatal obesity clinics to address the associated risks and reduce complications.
