Background: Our paper draws attention to the impact of lead (Pb) on the specificity of obesity development in children exposed to environmental pollution. An advantage of this paper is the homogeneous study group comprising children of identical age from a single geographic region. Moreover, while the influence of environmental toxins on adults has been extensively explored, this study delves into pediatric populations, which have yet to receive comprehensive scrutiny within the scientific literature. Methods: Initially, a group of 136 obese children (the research program lasted three consecutive years: 2016, 2017, and 2018) living in the north-western region of Poland, from whom biochemical tests and auxological data were obtained, were enrolled for analysis. Blood lead levels (BLLs) were determined in 115 children. The age of the children ranged from 7.1 to 10.4 years. The body mass index (BMI) of children averaged 21.5 ± 2.2. Results: The results showed that a large proportion of the participants had BLLs above the threshold for Pb. BLLs ≤ 5 µg/dL (considered safe for children and pregnant women) were found in over 70% of the participants, with BLLs in the range of 5.01–10.00 µg/dL in over 26% of the children, and concentrations > 10 µg/dL (considered toxic threshold for adults) in nearly 2% of the children. The results of our research revealed a positive association between BLLs and average systolic and diastolic blood pressure in the studied children. Moreover, we found a negative correlation between BLLs and absolute fat tissue content and triglyceride concentration. Among the included biochemical factors, only insulin demonstrated a statistically significant relationship with fat mass. This result suggests that early carbohydrate metabolism disorders in overweight children involve decreased peripheral tissue insulin sensitivity. Conclusions: Lead exposure may significantly contribute to the development of hypertension, insulin resistance, and glucose metabolism disorders in overweight and obese children. It is essential to implement multidirectional actions to increase awareness of the harmful effects of xenobiotic exposure, including lead, in order to prevent early-life exposure.

Objective: To comp+are levels of physical fitness between Ecuador and Spain and identify whether breastfeeding period, walking onset, and abdominal obesity are determinants of physical performance in schoolchildren from Ecuador and Spain. Methods: a total of 352 schoolchildren (6–12 years old) from Ecuador (n = 176) and Spain (n = 176) joined in this study. Anthropometric measures, socio-demographic characteristics, and physical fitness were evaluated. Results: Spanish schoolchildren showed better performance in handgrip strength, standing long jump, and 25 m sprint (p = 0.021; p < 0.001; p < 0.001; p < 0.001, respectively). Furthermore, Spanish children showed better cardiorespiratory fitness (p < 0.001) and a higher V O 2 max (p = 0.002) with regards to their peers. In addition, children from Ecuador and Spain showed an influence of breastfeeding period (p ranged from <0.001 to 0.043) and walking onset (p ranged from <0.001 to 0.032) on physical performance. Moreover, physical fitness components were protective factors of abdominal obesity in Ecuadorian and Spanish schoolchildren (p ranged from =0.001 to 0.049). Conclusions: Our findings revealed the influence of the infancy period and the onset of walking on children's physical performance, highlighting the importance of these factors in motor development during early childhood and also their influence in middle childhood and throughout adulthood.

Background: Per- and polyfluoroalkyl substances (PFAS) have been suspected as potential environmental obesogens, with several mechanisms being proposed, including the role of metabolomics. However, current epidemiological studies have yielded inconclusive findings. Objectives: We aimed to estimate the associations of prenatal exposure to PFAS with offspring adiposity measures, and to explore the potential metabolic pathways underlying these associations. Methods: A total of 464 mother–child pairs from the Sheyang Mini Birth Cohort Study (SMBCS) were included in this study. Cord serum concentrations of 12 PFAS and urine metabolite profiles at age 10 were obtained from the SMBCS database. Adiposity-related anthropometric measurements and body composition estimates of children aged 10 were used to assess offspring obesity. Multiple linear regression models and quantile g-computation were conducted to estimate the associations of prenatal exposure to individual and multiple PFAS with obesity at 10 years old. Metabolomics analysis was performed to characterize the biological pathways associated with PFAS exposure or obesity, subsequently identifying the overlapping metabolic pathways underlying the PFAS-obesity relationship. Results: Prenatal exposure to several PFAS was significantly associated with elevated obesity-related markers in 10-year-old children. After stratification by sex, the effects were more pronounced in girls. Quantile g-computation results indicated that exposure to higher levels of PFAS mixtures during pregnancy was associated with increased odds of obesity in girls, with PFNA emerging as the predominant driving compound. Untargeted metabolomics results showed that several amino acid metabolic pathways were characterized as the overlapping pathways underlying the above associations. Conclusions: Taken together, our findings suggested the potential obesogenic effects of prenatal exposure to PFAS and offered insight into the possible metabolic mechanisms underlying PFAS-related offspring obesity.

Children obesity is a serious public health problem drawing much attention around the world. Recent research indicated that gut microbiota plays a vital role in children obesity, and disturbed gut microbiota is a prominent characteristic of obese children. Diet and exercise are efficient intervention for weight loss in obesity children, however, how the gut microbiota is modulated which remains largely unknown. To characterize the feature of gut microbiota in obese children and explore the effect of dietary and exercise on gut microbiota in simple obese children, 107 healthy children and 86 obese children were recruited, and among of the obese children 39 received the dietary-exercise combined weight loss intervention (DEI). The gut microbiota composition was detected by the 16S amplicon sequencing method. The gut microbiota composition was significantly different between obese children and the healthy cohort, and DEI significantly reduced the body weight and ameliorated the gut microbiota dysbiosis. After DEI, the abundance of the Akkermansia muciniphila was increased, while the abundance of the Sutterella genus was decreased in simple obese children. Our results may provide theoretical reference for future personalized obesity interventions based on gut microbiota. [ABSTRACT FROM AUTHOR]

Previous studies have found that TLR4 rs1928295 polymorphism is associated with Body Mass Index in European and American Indian adults. This study evaluates the relationship between this locus polymorphism, obesity-related parameters and dietary patterns in Chinese Han Children. A total of 798 children aged 7–12 years were included in this cross-sectional study. An improved Multiple Ligase Detection Reaction was used for genotyping. Dietary patterns were identified by principal component factor analysis. The overweight/obesity rate of the TT genotype was greater than those of the CC/CT genotype (p = 0.032 and 0.048 in boys and girls, respectively). Boys of the TT genotype could interact with protein and cholesterol intake to increase low density lipoprotein (LDL) levels (p = 0.02, 0.015, respectively), while girls of the TT genotype could interact with total energy intake to increase triglyceride (TG) (p = 0.018) levels. Boys predisposed to a healthy balance dietary pattern (HBDP) and girls predisposed to an egg/fruit/fish dietary pattern (EFDP) were significantly associated with lower rates of central obesity (p = 0.045, 0.028). Boys carrying the TT genotype and predisposed to animal food dietary pattern (AFDP) had a higher level of low-density lipoprotein (p = 0.017) and systolic pressure (p = 0.044). Our results indicated that the TT genotype of TLR4 rs1928295 is a potential risk factor for obesity in Chinese Han children and is associated with dietary patterns. [ABSTRACT FROM AUTHOR]

Children carrying the minor allele 'A' at the fat mass and obesity-associated protein (FTO) gene have higher obesity prevalence. We examined the link between FTO rs9939609 polymorphism and plasma adiponectin and the mediating role of body adiposity, in a cross-sectional study comprising 323 children aged 6–11 years. Adiponectin and FTO genotypes were assessed using a commercial kit and a real-time polymerase chain reaction with high-resolution melting analysis, respectively. Body adiposity included body mass index z-score, body fat percentage and waist-to-hip ratio. To investigate adiponectin (outcome) associations with FTO and adiposity, linear regressions were implemented in additive models and across genotype categories, adjusting for sex, age and Tanner's stage. Using mediation analysis, we determined the proportion of the association adiponectin-FTO mediated by body adiposity. Lower adiponectin concentrations were associated with one additional risk allele (βadditive = −0.075 log-μg/mL [−0.124; −0.025]), a homozygous risk genotype (βAA/TT = −0.150 [−0.253; −0.048]) and a higher body mass index z-score (β = −0.130 [−0.176; −0.085]). Similar results were obtained for body fat percentage and waist-to-hip ratio. Body adiposity may mediate up to 29.8% of the FTO-adiponectin association. In conclusion, FTO rs9939609-related differences in body adiposity may partially explain lower adiponectin concentrations. Further studies need to disentangle the biological pathways independent from body adiposity. [ABSTRACT FROM AUTHOR]

Asian children are increasingly being diagnosed with type 1 diabetes (T1D) or type 2 diabetes (T2D), and the presence of coexisting islet autoimmune antibodies complicate diagnosis. Here, we aimed to determine the prevalence of islet cell autoantibodies (ICAs) and glutamic acid decarboxylase 65 autoantibodies (GADAs) in children with T1D versus T2D living in Vietnam. This cross-sectional study included 145 pediatric patients aged 10.3 ± 3.6 years, with 53.1% and 46.9% having T1D and T2D, respectively. ICAs were reported in only 3.9% of pediatric T1Ds, which was not significantly different from the 1.5% of those with T2D. Older children with T1D were positive for either ICAs, or ICAs and GADAs (5–9 and 10–15 years), whereas only a small proportion of children aged 0–4 years were positive for GADAs (18%). Notably, 27.9% of children with T2D aged 10–15 were positive for GADAs, and all were classified as overweight (n = 9) or obese (n = 10). GADAs were more commonly observed in T1D patients younger than four years than ICAs, which were more prevalent in older children (5–15 years). Even though few children with T2D carried ICAs and GADAs, finding a better biomarker or an appropriate time to confirm diabetes type may require further investigation. [ABSTRACT FROM AUTHOR]

Childhood obesity has become one of the major health issues in the global population. The increasing prevalence of childhood obesity is associated with serious health issues and comorbidities related to obesity. Several studies mentioned that childhood obesity became even worse recently due to the effect of COVID-19 and the consequent policies and regulations. For that reason, Internet of Things (IoT) technologies should be utilized to overcome the challenges related to obesity management and provide care from a distance to improve the health care services for obesity. However, IoT by itself is a limited resource and it is important to consider other artificial intelligent (AI) components. Thus, this paper contributes into the literature of child obesity management by introducing a comprehensive survey for obesity management covering clinical work measuring the association between sleep disturbances and childhood obesity alongside physical activity and diet and comparatively analyzing the emerging technologies used to prevent childhood obesity. It further contributes to the literature by proposing an interactive smart framework that combines clinical and emerging AI/telehealth technologies to manage child obesity. The proposed framework can be used to reduce children obesity and improve their quality of life using Machine Learning (ML). It utilizes IoT devices to integrate information from different sources and complement it with a mobile application and web-based platform to connect parents and physicians with their child.

• Prenatal PFAS exposure was associated with elevated risk of obesity in 10-year-old children. • The obesogenic effects related to PFAS were more pronounced in girls. • PFAS exposure was linked to perturbation in several metabolic pathways. • Dysregulation of amino acid-related pathways may contribute to PFAS-induced obesity.

Arterial hypertension is a serious clinical problem in everyday medical practice. It mainly affects adult patients, but is also increasingly common in children and adolescents. Making a diagnosis is possible thanks to systematic measurements of blood pressure during routine medical visits, while maintaining appropriate rules and referring to adequate biological norms - centile charts. Arterial hypertension in children and adolescents may be primary, but much more often than in the adult population, it occurs secondary to diseases of other organs and systems. Early diagnosis of hypertension in the developmental age gives a chance to implement adequate therapy by treating the underlying disease, lifestyle modification or pharmacological treatment. The aim of effective therapy of hypertension is to prevent the occurrence of early and long-term complications of the disease, as well as to reduce the risk of hypertensive emergencies.

Obesity in children contributes to higher risks of various chronic diseases in adulthood and the prevalence has increased worldwide including Japan. This study aims to examine the association between sleep duration at night in children aged 2.5 years and the subsequent risk of obesity at age 5.5 years. This study is embedded in the Longitudinal Survey on Babies Born in the 21st Century, which recruited families who had a child born in Japan in 2001. The multivariable logistic regression models were applied to calculate odds ratios (OR) and 95 % confidence intervals (CI) of childhood obesity at 5.5 years, defined as percentage of overweight (POW) ≥ 20 % and body mass index (BMI) ≥ 95th percentile of this study population according to sleep duration at night collected at 2.5 years child age. Among 25,378 children, 2.6 % and 3.7 % were obese at age 5.5 years defined by POW and BMI respectively. Compared with night sleep duration > 11 h/d, shorter sleep durations in 2.5 years-old children were associated with higher risk of obesity at 5.5 years; the multivariable ORs (95 %CI) were 1.05 (0.81–1.35), 1.23 (0.93–1.62) and 1.54 (1.04–2.31) for sleep duration 10, 9 and ≤ 8 h/d, respectively; p -trend = 0.03. The observed association differed according to the children (child's sex, napping habits, and children frequently play at park), and family characteristics (mother's age at delivery and mother's level of education). Short night sleep duration among girls aged 2.5 years was associated with risk of obesity at age 5.5 years, suggesting the importance of sufficient sleep duration at night for the prevention of obesity. • Short night sleep aged 2.5 years was associated with risk of obesity at age 5.5 years. • Girls with poor night's sleep duration appear to be at greater risk of obesity • Children with regular napping, who rarely or never played at a park, and whose mothers had younger ages at delivery and less education appear to be more at risk for obesity.

Childhood obesity is currently a global problem. This disease is spreading among the youngest at an alarming rate. It leads to many complications such as high blood pressure, high cholesterol, asthma, liver disease, type 2 diabetes, stroke and cancer. The risk factors for obesity include socioeconomic factors, poor diet, stress, low physical activity, and genetic factors. Research shows that neglect on each of these levels causes the development of the aforementioned disease. The priority of actions to prevent the occurrence of obesity among children is education about leading a healthy lifestyle from an early age. It should be run by parents, teachers at school and doctors. Currently, a major obstacle in the fight against obesity is the wide and easy availability on the market of processed products that are quick to prepare, high in calories and contain little nutrients. As a result of lack of time or lack of willingness, people more often reach for fast-food dishes, do not play sports, which unfortunately results in the development of the above-mentioned diseases. Undoubtedly, the problem of obesity among children and adolescents is growing. It is therefore important to prevent, quickly detect and treat this disease in its early stages and to build awareness among the population about the dangers of bad habits. This article is a review of current medical knowledge about children obesity based on available publications in Pubmed and Google Scholar databases.

Childhood obesity represents a serious public health problem and this study evaluates the effectiveness of a 6-month educational intervention on lifestyle, nutrient adequacy, and diet quality in the school setting in improving the knowledge and behavior of primary school children regarding correct eating habits. The strategy was implemented over a 6-month period and participants were randomly assigned to either the intervention group (n = 200) or the non-intervention group (control group, n = 197). Participants had a mean body mass index of 18.3 ± 2.7 kg/m2 and its variation in the intervention group (−2.7 ± 0.5 kg/m2) was significantly different from that in the control group (3.41 ± 0.8 kg/m2). In the experimental group, there were significant differences between the proportion of children who were overweight, underweight, normal weight, or obese before and after intervention (p < 0.05). The best results were seen in the female sex, and after the intervention, there were no more girls with obesity. Furthermore, there were significant waist circumference decrement effects in the intervention group compared to the control group (p < 0.05). Finally, many of the participating children acquired healthy eating habits. Therefore, the quantitative results obtained suggest that a school intervention program represents an effective strategy to prevent and improve the problem of childhood overweight and obesity.

Dietary patterns were identified by principal component factor analysis. The overweight/obesity rate of the TT genotype was greater than those of the CC/CT genotype (p = 0.032 and 0.048 in boys and girls, respectively). Boys of the TT genotype could interact with protein and cholesterol intake to increase low density lipoprotein (LDL) levels (p = 0.02, 0.015, respectively), while girls of the TT genotype could interact with total energy intake to increase triglyceride (TG) (p = 0.018) levels. Boys predisposed to a healthy balance dietary pattern (HBDP) and girls predisposed to an egg/fruit/fish dietary pattern (EFDP) were significantly associated with lower rates of central obesity (p = 0.045, 0.028). Boys carrying the TT genotype and predisposed to animal food dietary pattern (AFDP) had a higher level of low-density lipoprotein (p = 0.017) and systolic pressure (p = 0.044). Our results indicated that the TT genotype of TLR4 rs1928295 is a potential risk factor for obesity in Chinese Han children and is associated with dietary patterns.

The global prevalence of childhood obesity is high. Obesity main causes are linked to sedentary lifestyles. Increasing physical activity (PA) and reducing sedentary activities are recommended to prevent and treat obesity. This study aimed to evaluate the effectiveness of a 6‐month school PA intervention on obesity prevention and healthy behaviors in school‐aged children. Participating students (10–11 years of age) were randomly divided into an intervention group and a control group. Children in the intervention group (n = 80) participated in a multicomponent PA that included improvement in extracurricular physical activities (with an additional 40 min per day for 5/6 days per week). Children (n = 80) in the control group participated in usual practice. Participants had mean body mass index of 19.7 ± 2.9 kg/m2, and 33.7% of them were overweight or with obesity at T0. The change in body mass index in intervention group (−2.4 ± 0.6 kg/m2) was significantly different from that in control group (3.01 ± 1.8 kg/m2). The effects on waist circumference, waist‐to‐height ratio, and physic fitness were also significant in intervention group compared with control group (all p < 0.05). Furthermore, there is a significant decrease in overweight or children with obesity in the experimental group (to 17.5%, p < 0.05). These findings suggest that a school‐based intervention program represents an effective strategy for decreasing the number of overweight and children with obesity. [ABSTRACT FROM AUTHOR]

Children carrying the minor allele ‘A’ at the fat mass and obesity-associated protein (FTO) gene have higher obesity prevalence. We examined the link between FTO rs9939609 polymorphism and plasma adiponectin and the mediating role of body adiposity, in a cross-sectional study comprising 323 children aged 6–11 years. Adiponectin and FTO genotypes were assessed using a commercial kit and a real-time polymerase chain reaction with high-resolution melting analysis, respectively. Body adiposity included body mass index z-score, body fat percentage and waist-to-hip ratio. To investigate adiponectin (outcome) associations with FTO and adiposity, linear regressions were implemented in additive models and across genotype categories, adjusting for sex, age and Tanner’s stage. Using mediation analysis, we determined the proportion of the association adiponectin-FTO mediated by body adiposity. Lower adiponectin concentrations were associated with one additional risk allele (βadditive = −0.075 log-μg/mL [−0.124; −0.025]), a homozygous risk genotype (βAA/TT = −0.150 [−0.253; −0.048]) and a higher body mass index z-score (β = −0.130 [−0.176; −0.085]). Similar results were obtained for body fat percentage and waist-to-hip ratio. Body adiposity may mediate up to 29.8% of the FTO-adiponectin association. In conclusion, FTO rs9939609-related differences in body adiposity may partially explain lower adiponectin concentrations. Further studies need to disentangle the biological pathways independent from body adiposity.

Genetics can influence obesity, and when it affects both parents and children, there is a high risk of developing cardiometabolic diseases. Studies have indicated that family-based treatment (FBT) is a cost-effective and successful option for achieving significant weight changes in both children and parents. While specialized clinics offer FBT, primary care settings, where most pediatric care takes place, may not have the necessary resources or expertise to provide intensive behavioral interventions for childhood obesity. Based on early findings, FBT could potentially have a positive impact on siblings as well, as when treated children and parents experience behavioral changes, it can also have a beneficial effect on their untreated siblings. Parents play a crucial role in shaping their children's behavior, and siblings often have a stronger influence on them than their parents or friends. For our meta-analysis, we utilized three graphical models created using RevMan 5.4, based on the selected articles. To develop our systematic review, we thoroughly analyzed a total of 10 articles. The subgroup analysis within these studies assessed the effectiveness of FBT for overweight children, revealing no significant differences between groups (p=0.77). This suggests that based on their BMI, FBT may not have a statistically significant impact on weight loss in overweight children. However, each study reviewed showed statistical significance (p<0.05). The findings of our meta-analysis underscore the need for more robust evidence and larger randomized controlled trials (RCTs) to enhance our understanding of FBT's benefits in pediatric obesity. This will be crucial for reducing the rising prevalence of obesity and maintaining lower incidence rates., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

Perilipin 2 (PLIN2) regulates intracellular lipid metabolism in macrophages, and thus, plays a role in atherosclerosis. Aim of the study was to evaluate whether PLIN2 dysregulation is involved in the onset of preclinical atherosclerosis in children with overweight/obesity and to explore dysregulation mechanisms. Sixty-three children with overweight/obesity and 21 normal weight children (controls) of the same age and sex were enrolled. Carotid intima media thickness (cIMT) was evaluated; mRNA expression of PLIN2 and proteasome subunits (PSMD3 , PSMC4) was determined by Real Time PCR, and protein expression of PLIN2, LAMP2A and Hsc70 by Western blot analysis; fluorimetric assay was used to measure proteasome chymotrypsin like activity. We performed transient LAMP2A downregulation by siRNA and quantified intracellular lipids in monocytes by Nile Red staining and flow cytometry analysis. PLIN2 protein levels were significantly higher in children with overweight/obesity and correlated with cIMT after adjusting for confounders. Accordingly, monocytes of children with overweight/obesity showed a higher intracellular amount of lipids compared with controls. mRNA expression of the regulatory subunits PSMC4 and PSMD3 and proteasome activity were lower in children with overweight/obesity, while expression of LAMP2A and Hsc70 proteins, which belong to the chaperone-mediated autophagy (CMA) pathway, was not different, suggesting that PLIN2 dysregulation in monocytes was due to an impairment of proteasome efficiency and was not CMA related. PLIN2 was overexpressed in monocytes of children with overweight/obesity and could contribute to the onset of arteropathy. Our data suggest that proteasome impairment could contribute to PLIN2 overexpression. [Display omitted] • Lipid droplets Plin2 protein is overexpressed in monocytes of children with obesity. • Early arterial injury in children with obesity is associated with increased Plin2 protein expression in monocytes. • Plin2 upregulation could depend on proteasome impairment in children with obesity.

Neck circumference (NC) and wrist circumference (WrC) have been proposed as practical and inexpensive tools with the capacity to indicate metabolic alterations to some extent. Nevertheless, their application in the pediatric population is relatively recent. Thus, the aim of this scoping review was to review and analyze the reported evidence regarding the correlation of NC andWrC with metabolic alterations in the pediatric stage. The literature search was performed in January 2021 in seven indexes and databases. A total of 26 articles published between 2011 and 2020 were included. Most significant results were grouped into three categories: serum lipid profile, glucose homeostasis, and blood pressure. The parameter that showed the most significant results regardless of the anthropometric indicator analyzed for association was blood pressure. In contrast, total cholesterol and LDL-cholesterol showed non-significant associations along with conflicting results. We conclude that the use of NC and WrC, in addition to other well-established indicators, could facilitate the identification of metabolic alterations, specifically in plasma insulin and blood pressure. In fact, further studies are required to address the potential use of NC and WrC as predictors of early metabolic alterations, especially in countries with a fast-growing prevalence in obesity.

The prevalence of obesity continues to increase. Obesity is associated with cardiovascular risk factors: elevated blood pressure, dyslipidemia and glycemic alterations, causing metabolic syndrome. A subgroup of obese, Metabolically Healthy Obese (MHO), appears to be less prone to the development of metabolic disturbances. Carotid intima-media thickness (cIMT) is a non-invasive marker of subclinical atherosclerosis and it is associated with increased risk of CVD events. To investigate the cardiovascular risk, demonstrated through the increase of cIMT in obese subjects without Metabolic Syndrome (MetS), we have studied cIMT in MHO, metabolically unhealthy obese (MUO) and obese with MetS diagnosed with the IDEFICS criteria and compared to a control group. 224 obese children aged 6 to 21 years (13.50 ±4.01 years) and 103 normal weight subjects aged 7 to 19 years (13.2±4.1 years) were studied. The body mass index (BMI) of the obese children was ≥ the 95th percentile. Based on the IDEFICS criteria, we divided the obese subjects in three groups: MHO if no criteria were out of range, MUO if, at least, one of the criteria was out of range and MetS group if all the IDEFICS criteria were present. In all the subjects cIMT was measured with color Doppler by a vascular surgeon. Differences in the means of the variables were tested by ANOVA. Based on the IDEFICS criteria, 32 subjects were affected by MetS (14.3%), 66 were considered MUO (29.4%) and 126 MHO (56.3%). Comparison of mean cIMT highlighted a significant difference (p < 0.05) between the groups of obese children (MHO, MUO and MetS) and controls for both carotid arteries. We did not find significative difference in the value of cIMT in MHO, MUO and MetS subjects, and all groups showed cIMT value higher compared to cIMT of the controls. [ABSTRACT FROM AUTHOR]

Background: Prepubertal children with obesity frequently have enhanced growth, accelerated skeletal maturation and changes in the GH-IGF axis. However, the involvement of pappalysins (PAPP-A, PAPP-A2) and stanniocalcins (STC1, STC2) as regulators of IGF bioavailability has not been studied in obesity., Objective: We aimed to determine the effects of childhood obesity and weight reduction on serum levels of PAPP-A, PAPP-A2, STC1 and STC2 and their relationship with IGF bioavailability, growth, and other components of the GH-IGF system., Patients and Methods: Prepubertal children with severe obesity (150, 50% males/females, age: 7.72 ± 2.05 years, BMI z-score: 4.95 ± 1.70, height z-score: 1.28 ± 1.04) were studied at diagnosis and after a minimum of 0.5 BMI z-score reduction. Two hundred and six healthy age- and sex-matched children were used as controls., Results: Children with obesity had decreased serum concentrations of PAPP-A, PAPP-A2 and STC2, but increased total and free IGF-I (fIGF-I), intact IGFBP-3, ALS, IGF-II and insulin levels, with no difference in the free/total IGF-I ratio. Neither the standardized BMI nor height correlated with any biochemical parameter analyzed. A decrease in IGF-II, insulin, and ALS with an increase in IGFBP-2 and -5, STC2 and PAPP-A were observed after weight loss., Conclusion: Increased circulating total and free IGF-I, insulin and IGF-II may all contribute to the increased rate of prepubertal growth and bone maturation observed in children with obesity, with STC2 possibly being involved., (© The Author(s) 2024.

To assess, for the first time, the extent (by hour channel) and nature (e.g. persuasive marketing techniques (PMT) and health-related claims) of unhealthy food advertisements (ads) targeted at children (3–11 years) on the six most-watched television (TV) channels in Guatemala. We recorded 864 h of video on the six most popular channels featuring children's programmes. We classified food and beverage ads as permitted or non-permitted for marketing to children, according to the 2015 World Health Organisation (WHO) nutrient profile. Furthermore, we also analysed PMT (i.e. premium offers, promotional characters, brand benefit claims) and health-related claims. Most food ads (85%) were non-permitted to be marketed to children. Non-permitted food ads were six times more likely, either on weekdays or weekends, for all programme and channel categories compared with permitted food ads. There was no difference in the frequency of non-permitted food ads between peak and non-peak hours, weekend and weekdays or children and non-children programmes. PMT and health-related claims were present in all food ads (5.3 ± 1.9 techniques/claims per ad). There is a need to regulate food ads on TV channels featuring children's programmes in Guatemala as a result of a high frequency of non-permitted food ads and extensive use of PMT together with health-related claims.

The coexistence of childhood obesity (or its risk) and COVID-19 pandemic put children and adolescents in greater risk to develop respiratory and cardiovascular diseases. In fact, the restrictions introduced to limit the spread of the virus had detrimental effects on various lifestyle components, especially in young population. This resulted in augmented levels of physical inactivity and sedentary behaviors and a reduced time spent in play outdoors or sport practices. Contrariwise, the increased use of technology led clinicians, teachers, and trainers to maintain relations with obese children/adolescents so as to reduce sedentary behaviors and the associated health risks. This narrative review aims to describe the role of Telehealth and Tele-exercise as useful tools in the management of pediatric obesity during COVID-19 pandemic. Telehealth and Tele-exercise were effective in promoting self-monitoring and behavioral changes, including adherence to exercise training programs in children and adolescents. Moreover, tele-exercise platforms such as applications or exergames allowed flexible scheduling, limiting the infection risks.

Obesity in children is attended by increased circulating leptin concentrations. Girls have higher leptin Concentrations than boys. IL-6 levels related positively with BMI and percent fat mass (PFM). The Objective: Was to detect the serum IL-6 and levels of leptin among girls and boys as obese and other biochemical parameters related with obesity. Methodology: This study involved 60 children were classified into 2 groups; 30 obese ones (fifteen girls and boys fifteen) and 30 control (fifteen girls and fifteen boys) with years of seven- fifteen old who attended to the Obesity Research and Treatment Unit/ Al kindy Medical College, during the period January 2017 - July 2017. A clinical examination and diagnosis were done for each patient by the consultant medical staff and the biochemical laboratory examination results (FBS, blood urea, serum creatinine, lipid profile, serum GOT, serum GPT, SCa and uric acid) were as a routine work. They compared with 30 healthy children with approximate age with patients. The sera were assessed for IL-6 and leptin by an ELISA kit. Results: Showed no significant differences among obese children (boys and girls) except the GPT and GOT were both higher significantly (P<0.05) in male (42.46±34.27 and 33.3±13.6) than in girls (53.6 ±75.1 and 29.9±14.1). Whereas, obese girls revealed a significant increasing in (STRIG 120.3±26.7 P≤0.01, SLDL 89.3±25.5 P ≤0.05, GOT 33.1±13.6 P ≤0.01, GPT 29.9±14.1 P ≤0.01 and LIPTIN 2758.4±539.1 P ≤0.001) in comparison to the control girls. Similarly, for boys highly significant increasing appeared in (SLDL 90.92±18.1, GOT 42.46±34.27, GPT 53.6±75.1 and LIPTIN 2883.93±512.7 P ≤0.001), as well as in STRIG. 69±.13 P ≤0.05 then normal boys. Inversely, it has been shown that (BURIA 26.7±5.3 P ≤0.05, SCREAT. 69±.13 P ≤0.01 and SVLDL 20.15±6.3 P ≤0.01) were decreased significantly. In boys IL-6 showed significant positive correlation with BMI, while leptin revealed strong associated was with IL-6 Conclusion: Obesity associated with elevated blood leptin and IL-6 levels. Leptin and IL-6 play keys role as a biomarker for childhood obesity, and can help in the prediction of get weight in obese children as well as its important interrelationship with other parameters.

Introduction: The aim of this study is to evaluate short- and long-term consequences in children born to women after different bariatric surgery (BS) procedures. Methods: A questionnaire survey was given to the mothers referred from 1994 to 2019 to our center for pregnancy and delivery management after BS procedures: (a) malabsorptive surgery, (b) restrictive procedures, and (c) combined restrictive-malabsorptive procedures. Results: Data from 74 children born after BS, aged 0 month to 12 years, were analyzed. The prevalence of children with underweight was 5.4%, normal weight 59.5%, overweight 16.2%, and obesity 18.9%. The prevalence of obesity was higher in children pre-school aged than that in school-aged ones. Neurodevelopmental disorders were more frequent if maternal BMI before bariatric surgery was ≥ 41 kg/m2 (p = 0.008), as well as if the pregnancy occurred less than 18 months after BS (p = 0.028). In school-aged children conceived within 18 months after BS, the highest risk of neurodevelopmental disorders (p = 0.028) and overweight (p = 0.018) was observed. The prevalence of neurodevelopmental disorders was much higher for small for gestational age babies (p = 0.048). Children born after biliopancreatic diversion (BPD) showed less maternal breastfeeding, shorter breastfeeding duration, more overweight, and more occurrence of atopic dermatitis in comparison with children born after other bariatric procedures. Conclusions: Postnatal health in children born to women after BS was impaired by long-term consequences and by other diseases later in life. Children born after BPD were particularly at higher risk for short and long term consequences when compared to children born after other BS procedures. [ABSTRACT FROM AUTHOR]

Objective: To find the correlation between the presence of childhood obesity and bone mineral density (BMD). Materials and Methods: A cross-sectional study was conducted among children aged between 5 and 12 years old. After excluding children who had history of endocrinopathy, epilepsy, or cerebral palsy, all participants were divided into "obese group" (body mass index [BMI] at or above the 95 percentile of those with the same age and gender) and "control group" (BMI below the 95 percentile). Skeletal age, BMD, serum bone markers (osteocalcin and beta-crosslaps), and physical exercise were collected. Multivariate regression analysis was used for statistical analysis. Results: Ninety-six obese children and 98 controls were included in the present study. The average BMI was 28.5 kg/m? in obese group, and 16.6±1.9 kg/m? in controls (p<0.001). BMDs of the spine and hip area were significantly higher in obese group compared to controls (p=0.002 and <0.001, respectively). However, there was no significant difference of skeletal age or serum bone markers level between both groups (p>0.05 all). Exercise was shown to significantly correlated with hip and distal radius BMD (p<0.001 and 0.003, respectively). Conclusion: Obese children had significantly higher spine and hip BMD than non-obese children. Nevertheless, there were no differences between groups regarding skeletal age and bone markers. BMI and exercise activity might play an important role in higher BMD in children. [ABSTRACT FROM AUTHOR]

Introduction. obesity is one of the most common health problems of the developed countries. the prevalence is increasing amongadults and children alike. in hungary, the prevalence in children is 9-10%. in 1998, Who (World health organization) classifiedobesity as a disease. obesity, and other metabolic, endocrine and musculoskeletal diseases that are caused by obesity are seen asone of the biggest public health-related problem nowadays. obesity increases the morbidity and mortality in all the populations.Aim. the aim of our screening program was to investigate the prevalence of obesity and its association with hypertension inchildren.Material and methods. A screening program was conducted between April 2010 and may 2011. the screening consisted ofmeasuring blood pressure, heart rate, cholesterol, blood glucose, weight, height, calculating Bmi, and determination of bodycomposition.Results. 2226 children aged 14-18 fullfilling the inclusion criteria participated in the program. 13% of the participantswere overweight (i.e. their Bmi was in between the 85th and 95th percentile of the Bmi for their age) and 4% of them wereobese (i.e. their Bmi was above the 95th percentile for their age). high body fat content was detected in 12.98% of girlsand 5.9% of boys that participated in the study. 66% of girls and 81% of boys with elevated Bmi had high body fat content.mean cholesterol level was significantly higher in the group of overweight and obese participants than in the group of participants with normal Bmi. mean systolic and diastolic blood pressure differed significantly between groups with differentBmi for both girls and boys, with overweight participants most likely to have pathologically high blood pressure.Conclusions. there was a significant increase in both systolic and diastolic blood pressure with an increase in Bmi. the resultsof our study may help design preventive programmes for obesity and hypertension in children.

Neck circumference (NC) and wrist circumference (WrC) have been proposed as practical and inexpensive tools with the capacity to indicate metabolic alterations to some extent. Nevertheless, their application in the pediatric population is relatively recent. Thus, the aim of this scoping review was to review and analyze the reported evidence regarding the correlation of NC and WrC with metabolic alterations in the pediatric stage. The literature search was performed in January 2021 in seven indexes and databases. A total of 26 articles published between 2011 and 2020 were included. Most significant results were grouped into three categories: serum lipid profile, glucose homeostasis, and blood pressure. The parameter that showed the most significant results regardless of the anthropometric indicator analyzed for association was blood pressure. In contrast, total cholesterol and LDL-cholesterol showed non-significant associations along with conflicting results. We conclude that the use of NC and WrC, in addition to other well-established indicators, could facilitate the identification of metabolic alterations, specifically in plasma insulin and blood pressure. In fact, further studies are required to address the potential use of NC and WrC as predictors of early metabolic alterations, especially in countries with a fast-growing prevalence in obesity.

Purpose: The relationships between gut microbiota and obesity-related co-morbidities have been increasingly recognized. Low-grade inflammation may be the main factor in the pathogenesis of such disorders. We investigated the effect of the potential probiotic Bifidobacterium pseudocatenulatum CECT 7765 on cardiometabolic risk factors, inflammatory cytokines and gut microbiota composition in obese children with insulin resistance. Methods: The study included 48 obese children (10–15 years old) with insulin resistance. They received dietary advice and were assigned to take the capsules with or without probiotic (109−10 CFU) daily for 13 weeks. Clinical, biochemical and gut microbiome measurements were made at baseline and at the end of the intervention. Results: There was a significant improvement in body mass index in all children after the intervention, suggesting that weight changes are related to the dietary advice. A significant decrease in circulating high-sensitive C-reactive protein (P = 0.026) and monocyte chemoattractant protein-1 (P = 0.032) and an increase in high-density lipoprotein cholesterol (P = 0.035) and omentin-1 (P = 0.023) in children receiving probiotic supplementation were observed compared to the control group. Regarding gut microbiota, probiotic administration significantly increased the proportion of the Rikenellaceae family members, particularly of the Alistipes genus. Conclusions: The beneficial effects of the intervention on inflammatory markers and lipid profile suggest that B. pseudocatenulatum CECT 7765 intake together with dietary recommendations can improve inflammatory status in children with obesity and insulin resistance. These effects are parallel to increases in bacterial groups associated with a lean phenotype. The modulation of gut microbiota with probiotic supplementation can be considered an effective tool to ameliorate some obesity-related disorders in children. [ABSTRACT FROM AUTHOR]

Abstract Background To explore the extent and nature of television food advertising especially unhealthy food advertising to primary school children in Xi’an, China. Methods Television data were recorded for 2 weekdays and 2 weekend days between 6:00 and 22:00 during May and June in 2012 from a total of five television channels most popular with children in Xi’an. Pearson χ2 tests and logistic regression were applied to determine differences in the proportion of healthy food, unhealthy food and miscellaneous food advertisements for different channels, programs, dates, viewing periods and the use of persuasive marketing tactics. Results Of the 5527 advertisements transcribed, 25.5 % were for food, among which 48.1 % were considered to be unhealthy. The frequency of food advertisements was 6 per hour per channel, including 3 unhealthy food advertisements. Compared with healthy and miscellaneous food advertisements, more unhealthy food advertisements were shown during afternoon, weekends and children’s non-peak viewing times as well as on children’s television channels, central television channels and non-children’s programmes. Unhealthy foods contributed the highest proportion of all food advertisements containing promotional characters (51.7 %) and premium offers (59.1 %). Both promotional characters and premium offers appeared more on non-children’s television channels. Conclusions The majority of food advertisements were for unhealthy food. More unhealthy food ads were shown in children’s non-peak time and afternoon as well as non-children’s channels. More children-oriented persuasive marketing tactics were used in unhealthy food ads especially in non-children’s channels. Therefore, intervening in the entrance of unhealthy foods into the market and establishing regulations related to food advertising especially unhealthy food advertisements are important strategies to prevent children’s exposure to unhealthy food and childhood obesity.

Obesity is a major health problem worldwide and constitutes a sanitary emergency in Mexico, especially childhood obesity. Several studies have proved the relationship between obesity and oxidative stress and the influence of genetic predisposition. This work was aimed to analyze the association of antioxidant enzyme polymorphisms with overweight and obesity in Mexican children and adolescents. A case-control study was performed in 585 children and adolescents aged 3 to 17 years, using two criteria to classify obesity: body mass index (BMI) and body fat percentage (BFP). Anthropometric and biochemical measurements were carried out, and malondialdehyde serum levels were determined. Genotyping was done with the Axiom Genome-Wide LAT microarray, including 68 single nucleotide polymorphisms (SNPs) of the glutathione peroxidase (GPX) and paraoxonase (PON) families. We found six haplotypes associated with obesity—two of them (one in GPX3 and the other in GPX5 and GPX6) in a protective direction when obesity was classified by BMI. The other four haplotypes were associated with obesity when classification was based on BFP—one of them in GPX3 in a protective direction and the others in PON genes conferring obesity risk. In addition, two SNPs, GPX3 rs922429 and GPX4 rs2074451 showed protection against obesity classified by BFP. This study showed genetic susceptibility to oxidative stress in relation to obesity in Mexican children and opens up the possibility that some genetic loci related to obesity are not identified when weight classification is based on BMI.

Childhood obesity is one of the most difficult public health issues. According to "The Lancet" magazine, there are 124 million obese children in the world. The frequency of this disease in developed countries, including Poland, is constantly increasing. We can already talk about the obesity epidemic. Despite additional diseases, obesity has an economic impact in terms of combating its complications. Therefore, it is necessary to search for unknown risk factors as well as methods of their treatment. In order to obviate this disease, more and more preventive actions are being organised. However, education is not enough - joint actions undertaken by the authorities, society and representatives of the food industry are needed.

Phthalates and bisphenol A (BPA), plasticizers used in several products of daily life, are considered as endocrine disrupters, therefore children exposure is particularly relevant. The LIFE PERSUADED project aims to define the following: (a) the evaluation of internal levels of DEHP’s metabolites and BPA in Italian children and their mothers, (b) the association of the exposure with puberty development and obesity diseases, and (c) the effects of exposure in juvenile in vivo model. The cross-sectional study has involved 2160 mother-child pairs, including males and females, children and adolescents, from urban and rural areas of North, Center, and South Italy. A structured questionnaire and a food diary are designed to evaluate the association between lifestyle variables potentially related to DEHP/BPA exposure and internal levels, through univariate and multivariate analyses. Two pilot case-control studies are carried out on idiopathic premature thelarche and precocious puberty (30 girls each group, aged 2-7 years) and idiopathic obesity (30 boys and 30 girls, aged 6-10 years), matched to healthy controls. BPA and DEHP’s metabolites are analyzed in urine samples from all recruited subjects. Clinical and toxicological biomarkers are evaluated in serum of case-control subjects. Moreover, the toxicity study is carried out in a juvenile rodent model exposed to mixtures of BPA and DEHP at dose levels recorded in children population. The scientific results of LIFE PERSUADED will contribute to risk assessment of BPA and DEHP. [ABSTRACT FROM AUTHOR]

Childhood obesity consists one of the most significant problems of public health in 21st century as in the last 30 years the number of overweight/obese children has increased dramatically. The increasing intake of processed and rich in saturated fat foods has mainly contributed to the expansion of this situation. Parents' nutritional behavior, as role models, regarding the consumption of processed products has not been adequately investigated. Therefore, this review paper aimed to examine the association between parents' child eating habits and particularly on the consumption of high-fat food and processed products. Literature search was conducted in databases of PubMed and Scopus, from 1970 to 2019, in order to reveal epidemiologic studies, using as keywords: "children obesity, parents, high-fat processed food, food supply, role modeling". According to the provided data, it was observed that parents have a pivotal role on children's nutritional behavior and the most important was that trends towards the consumption of processed foods have been increased alarmingly. An urgent need, therefore, is to implement an intervention to reverse this phenomenon, mainly focused on the family's nutritional quality. [ABSTRACT FROM AUTHOR]

The objective was to verify the nutritional status of children attending public and private institutions based on anthropometric measures. An evaluation of the Nutritional Status of children from 02 to 04 years old, from the public and private schools was carried out. The anthropometric status was evaluated from BMI (BMI / Age), P / I (weight for age), E / I (height for age), and P / E (weight for height). Data were collected according to the anthropometric measures and later processed in WHO tables. According to the P / I parameter, 11.11% (n = 3) of the day care center children were weight-for-age. Analyzing the same parameter, it was possible to observe that 6.5% (n = 2) of the children in the private day care center presented weight for age. Regarding the E / I index, 11.11% (n = 3) of the children in the public network was diagnosed with short stature, while those in the private network showed 100% adequacy in this parameter. The IMC / I indicator presented a prevalence of 44.44% (n = 12) and 16.1 (n = 5) of obesity in children in the public and private day care centers, respectively. According to the P / E, 55.6% (n = 15) of the children in the public network presented obesity, and 16.1% (n = 5) of the private day care center presented the same diagnosis. According to the results, it was concluded that there is an increase in overweight in the children of the public network when compared to those of the private network. [ABSTRACT FROM AUTHOR]

Estudios epidemiológicos americanos alertan de la creciente inactividad mundial y predicen que los niños de hoy son la primera generación que tiene una expectativa de vida menor que sus padres. (Designed to Move, 2014) La inactividad física es el cuarto factor de riesgo de mortalidad en la población actual dentro del mundo desarrollado, origina el 6% de las defunciones a nivel mundial. España es uno de los países del mundo más afectados por la epidemia de la inactividad, lo que aumenta el riesgo de enfermedad cardiovascular, de diabetes, de obesidad, de síndrome metabólico descendiendo la expectativa de vida (Gennuso, Gangnon, Matthews y Thraen-Borowski, 2013). Esta conducta inactiva aumenta con la edad y es mayor en aquellas personas que padecen alguna patología crónica. Actualmente los niños y jóvenes también se ven afectados por esta conducta lo que realmente anuncia un futuro lamentable para la edad adulta ya que la enfermedad cardiovascular se gesta desde la juventud y progresa durante mucho tiempo afectada por la suma de las malas conductas adquiridas. Permanecer inactivo, disminuye la condición física, siendo la baja condición física un factor de riesgo de mortalidad mayor que fumar, tener un alto índice de masa corporal, padecer hipercolesterolemia, padecer diabetes o hipertensión (Blair, S.N. 2009). La Organización Mundial de la Salud estima que la inactividad física causa en conjunto 1,9 millones de defunciones a nivel mundial, en torno a un 10% - 16% de los casos de cáncer de mama, cáncer colorrectal y diabetes mellitus, y aproximadamente un 22% de los casos de cardiopatía isquémica (OMS 2002).

Background. Nutrition in early life is increasingly considered to be an important factor influencing later health. Food preferences are formed in infancy, are tracked into childhood and beyond, and complementary feeding practices are crucial to prevent obesity later in life. Methods. Through a literature search strategy, we have investigated the role of breastfeeding, of complementary feeding, and the parental and sociocultural factors which contribute to set food preferences early in life. Results. Children are predisposed to prefer high-energy, -sugar, and -salt foods, and in pre-school age to reject new foods (food neophobia). While genetically determined individual differences exist, repeated offering of foods can modify innate preferences. Conclusions. Starting in the prenatal period, a varied exposure through amniotic fluid and repeated experiences with novel flavors during breastfeeding and complementary feeding increase children's willingness to try new foods within a positive social environment.

The prevalence of obesity has increased at an alarming rate worldwide. Metallic elements are involved in the pathogenesis of obesity and related diseases. To date, whether environmental exposure to metallic elements has effects on obesity in children and adolescents is still unclear. The aim of the current study was to investigate the association of blood metallic elements with obesity in U.S. children and adolescents. This cross-sectional study was performed with 5404 children and adolescents (6-19 years, 2745 males and 2659 females) who participated in the US National Health and Nutrition Examination Survey 2011-2014. Blood lead, mercury, selenium, manganese, copper, and zinc, as well as biochemical parameters including triglyceride (TG), cholesterol, low-density lipoprotein (LDL), and homeostasis model assessment of insulin resistance (HOMA-IR) were assessed for all subjects. Multivariate logistic regression and linear regression were applied to assess associations of metallic elements and overweight, obesity status, and serum metabolites as distinct outcomes adjusted for age, gender, ethnicity, and the poverty income ratio. When stratified by age and sex, significant associations were found between the highest quartile of copper concentrations in blood with obesity status (OR = 9.27,95% CI: 5.43,15.82, pfor trend < 0.001) and cholesterol (OR = 3.08,95% CI: 1.43, 6.63, pfor trend < 0.001). The highest concentrations of manganese in the blood was associated with obesity in those aged 6-19 years (OR = 2.29,95% CI: 1.74,3.02, pfor trend < 0.001). Moreover, blood mercury and selenium showed positive relationships with cholesterol. Further, a negative association existed between blood zinc and obesity. The National Health and Nutrition Examination Survey data provide epidemiological evidence that blood metallic elements are positively associated with obesity in children and adolescents. However, the underlying mechanisms still need further exploration. [ABSTRACT FROM AUTHOR]

Background: The prevalence of children obesity is rising alarmingly in both developed and developing countries. Developing effective exercise programs is a strategy for decreasing this prevalence and limiting obesity-associated long-term comorbidities. Objectives: To determine whether a 16-week training program; in addition to the school physical education and without dietary intervention; could have beneficial effects on body composition and aerobic capacity of obese children. Materials and Methods: Twenty-eight obese children (16 boys, 12 girls; aged 12-14 years) were enrolled and were divided into either the exercise group (EG, n = 14) or the control group (CG, n = 14). EG participated in a 16-week aerobic exercises (four 60-min sessions per week at 70-85% of HRmax (maximum heart rate)), in addition to the school physical education. Fat-Free Mass (FFM) and Fat Mass (FM) were assessed with bioelectrical impedance equipment. To assess aerobic capacity, maximal metabolic equivalent of task (METmax) and maximal workload (Wmax) were estimated with an electronically braked cycle ergometer (type Ergoline 500® ). Results: At baseline, there were no differences between the two groups. After the training program, only the EG showed significant reduction in BMI (body mass index) and waist circumference compared with the baseline values (P < 0.001). Exercise training significantly decreased FM only in the EG. A significant increase in FFM was seen in both groups; more marked in the EG. There was a significant increase in METmax (P < 0.05) and Wmax (P = 0.02) in the EG, and no significant changes in these parameters were seen in the CG. HRmax significantly decreased only in the EG (P < 0.05). Conclusion: This training program has beneficial effects on body composition and aerobic capacity parameters in obese children. Our intervention has the advantage of providing a sustainable and reproducible school and community approach for the management of children obesity.
