    To determine the effect of feeding frequency on appetite in normal weight (NW) and obese (OB) prepubertal children, we carried out a prospective, randomized interventional study of 18 NW and 17 OB children ages 6-10. Children received three or five feedings in random order on separate days. Total calories, carbohydrate, protein, and fat composition on each day were equal. Two hours following the last feeding, children were offered ice cream ad lib. The major outcome variable was kilocalories ice cream consumed. A visual analog scale to assess fullness was also administered before consumption of ice cream. We observed that OB children consumed 73.0 ± 37.4 kcal more after five feedings than after three feedings whereas the NW children consumed 47.1 ± 27.8 kcal less. There was significant interaction between meal pattern and weight group indicating that this change in ice cream consumption differed significantly between groups (P = 0.014 by two-factor analysis). Ice cream intake/kg was less in OB compared to NW subjects (P = 0.012). Fullness ratings before ice cream did not differ by meal pattern or weight group. However, pre-ice cream fullness predicted ice cream intake in NW but not OB children. In summary, OB and NW children differed in appetite response to meal frequency. Our data suggest that: (i) satiety in OB children is related more to proximity of calories (larger supper) than to antecedent distribution of calories and; (ii) NW children may be more prone to restrict intake based on subjective fullness.

    Characterization of the genes expressed in adipose tissue (AT) is key to understanding the pathogenesis of obesity and to developing treatments for this condition. Our objective was to compare the gene expression in visceral AT (VAT) between obese and normal-weight prepubertal children. A total of fifteen obese and sixteen normal-weight children undergoing abdominal elective surgery were selected. RNA was extracted from VAT biopsies. Microarray experiments were independently performed for each sample (six obese and five normal-weight samples). Validation by quantitative PCR (qPCR) was performed on an additional 10 obese and 10 normal-weight VAT samples. Of 1276 differentially expressed genes (p < 0.05), 245 were more than two-fold higher in obese children than in normal-weight children. As validated by qPCR, expression was upregulated in genes involved in lipid and amino acid metabolism (CES1, NPRR3 and BHMT2), oxidative stress and extracellular matrix regulation (TNMD and NQO1), adipogenesis (CRYAB and AFF1) and inflammation (ANXA1); by contrast, only CALCRL gene expression was confirmed to be downregulated. In conclusion, this study in prepubertal children demonstrates the up- and down-regulation of genes that encode molecules that were previously proposed to influence the pathogenesis of adulthood obesity, as well as previously unreported dysregulated genes that may be candidate genes in the aetiology of obesity.

    Background: Insulin resistance (IR) is usually the first metabolic alteration diagnosed in obese children and the key risk factor for development of comorbidities. The factors determining whether or not IR develops as a result of excess body mass index (BMI) are still not completely understood. Objectives: This study aimed to elucidate the mechanisms underpinning the predisposition toward hyperinsulinemia-related complications in obese children by using a metabolomic strategy that allows a profound interpretation of metabolic profiles potentially affected by IR. Methods: Serum from 60 prepubertal obese children (30 girls/30 boys, 50% IR and 50% non-IR in each group, but with similar BMIs) were analyzed by using liquid chromatography–mass spectrometry, gas chromatography–mass spectrometry and capillary electrophoresis–mass spectrometry following an untargeted metabolomics approach. Validation was then performed on a group of 100 additional children with the same characteristics. Results: When obese children with and without IR were compared, 47 metabolites out of 818 compounds (P<0.05) obtained after data pre-processing were found to be significantly different. Bile acids exhibit the greatest changes (that is, approximately a 90% increase in IR). The majority of metabolites differing between groups were lysophospholipids (15) and amino acids (17), indicating inflammation and central carbon metabolism as the most altered processes in impaired insulin signaling. Multivariate analysis (OPLS-DA models) showed subtle differences between groups that were magnified when females were analyzed alone. Conclusions: Inflammation and central carbon metabolism, together with the contribution of the gut microbiota, are the most altered processes in obese children with impaired insulin signaling in a sex-specific fashion despite their prepubertal status.

    The prevalence of obesity in children has increased dramatically during the past decades in Europe and understanding physical fitness and its components in children is critical to design and implement effective interventions. The objective of the present study was to analyse the association between physical fitness (aerobic, speed, agility, power, flexibility and balance) and body mass index (BMI) in pre-pubertal children. A total of 2411 healthy schoolchildren (7-11 years) participated in this study. Anthropometric characteristics and body composition were assessed by skinfold thickness. Physical fitness was measured by nine physical fitness tests: endurance running, 20 m running speed, agility, handgrip strength, standing long jump and squat jump, sit and reach, medicine ball forward throw and static balance. No relevant differences were observed between boys and girls regarding anthropometric characteristics, body composition and physical fitness. However, overweight and obese children showed significantly lower physical fitness levels in endurance running, speed and agility (mean: +18.8, +5.5 and +14.5% of time to complete tasks, respectively), lower limb power normalised to body mass (-23.3%) and balance tests (number of falls: +165.5%) than their normal weight counterparts. On the other hand, obesity did not affect handgrip, throwing and flexibility. In conclusion, increased BMI was associated with lower performance capabilities limiting proper motor skill development, which directly affects the ability of children to take on sports skills. Actions undertaken to promote children's wellness and fitness should be prioritised and introduced early in life with the aim of enhancing physical fitness as well as preventing overweight and obesity.

    The pulmonary oxygen uptake response is deleteriously influenced by obesity in prepubertal children, as evidenced by a slower phase II response. To date, no studies have investigated the ability of an exercise intervention to ameliorate this. The objective of the study was to investigate the influence of a 6-week, high-intensity, games-orientated intervention on the oxygen uptake kinetic response of prepubertal obese and normal-weight children during heavy-intensity exercise. Thirteen normal-weight and 15 obese children participated in a twice-weekly exercise intervention involving repeated bouts of 6-min high-intensity, games-orientated exercises followed by 2 min of recovery. Sixteen normal-weight and 11 obese children served as a control group. At baseline and post-intervention, each participant completed a graded-exercise test to volitional exhaustion and constant work-rate, heavy-intensity exercise. Post-intervention, obese children demonstrated a reduced phase II τ (pre-intervention: 30 ± 8 cf. post-intervention: 24 ± 7 s), mean response time (pre-intervention: 50 ± 10 cf. post-intervention: 38 ± 9 s) and phase II amplitude (pre-intervention: 1.51 ± 0.30 cf. post-intervention: 1.34 ± 0.27 L·min(-1)). No changes were evident in the normal-weight children. In conclusion, the present findings demonstrate that a 6-week, high-intensity intervention can have a significant positive impact on the dynamic oxygen uptake response of obese prepubertal children.

    Background. Low-grade inflammation is the link between obesity and insulin resistance. Because physiologic insulin resistance occurs at puberty, obese pubertal children are at higher risk for insulin resistance. Excessive diets in refined carbohydrates and saturated fats are risk factors for insulin resistance, but calcium, magnesium, vitamin-D, and the omega-3 fatty acids likely protect against inflammation and insulin resistance. Objective. To analyze interactions among dietary saturated fat, refined carbohydrates, calcium, magnesium, vitamin D, and omega-3 fatty acids on the risk of inflammation and insulin resistance in a sample of prepubertal and pubertal children. Methods. A sample of 229 children from Mexico City was analyzed in a cross-sectional design. Anthropometric measurements, 24 h recall questionnaires, and blood samples were obtained. Serum insulin, glucose, calcium, magnesium, 25-OHD3, C-reactive protein, leptin, adiponectin, and erythrocytes fatty acids were measured. Parametric and nonparametric statistics were used for analysis. Results. While mean macronutrients intake was excessive, micronutrients intake was deficient (P < 0.01). Inflammation determinants were central obesity and magnesium-deficient diets. Determinants of insulin resistance were carbohydrates intake and circulating magnesium and adiponectin. Conclusions. Magnesium-deficient diets are determinants of inflammation, while high intake of refined carbohydrates is a risk factor for insulin resistance, independently of central adiposity. PMID:25477716

    In obese adults with non alcoholic fatty liver disease (NAFLD), treatment with Vitamin E has resulted in an improvement in liver histology, whereas variable and limited results are available in children. Our aim was to assess whether lifestyle combined with supplementation with Vitamin E might reduce oxidative stress and improve cardio-metabolic status in obese children with NAFLD. 24 obese prepubertal children (16M) followed a 6-month lifestyle intervention combined with Vitamin E supplementation (600 mg/day) and they were compared with 21 age and sex-matched obese peers who underwent lifestyle intervention only. At baseline and after 6-month urinary prostaglandin F2α (PGF-2α), endogenous secretory receptor for advanced glycation end products (esRAGE), high sensitivity C-reactive protein (hs-CRP), alanine aminotransferases (ALT), lipid profile, glucose, and insulin were assessed. The two groups were comparable for age (8.3 ± 1.6 vs 8.4 ± 1.3 yr), sex and BMI SDS (2.16 ± 0.29 vs 2.13 ± 0.28). At the beginning of the study, PGF2-α, esRAGE hsCRP, ALT, lipid profile and HOMA-IR levels were similar between the two groups (all p > 0.05). After 6-month treatment, levels of PGF2-α (p < 0.001) significantly decreased and esRAGE significantly increased (p < 0.001) in children treated with Vitamin E. A significant reduction was also found in ALT (p = 0.001), lipid profile and HOMA-IR (p < 0.001). In contrast, no significant change in any of these markers was detected in the lifestyle only group. In conclusion, Vitamin E supplementation was associated with a significant reduction in oxidative stress and improved cardio-metabolic alterations. These data suggest that Vitamin E supplementation could represent a valuable treatment in obese children affected by NAFLD.

    In obese individuals, weight loss might be affected by variants of the adipokine-encoding genes. We verified whether selected functional single nucleotide polymorphisms in LEP, LEPR and ADIPOQ are associated with changes in serum levels of the respective adipokines and weight loss in 100 prepubertal obese (SDS-BMI > 2) Caucasian children undergoing lifestyle intervention. Frequencies of the -2548G > A LEP, Q223R LEPR, K656N LEPR, -11377C > G and -11426A > G ADIPOQ polymorphisms were analyzed by restriction fragment length polymorphism. Serum adipokine and soluble leptin receptor (sOB-R) concentrations were measured using the ELISA method. Among the analyzed polymorphisms, only LEPR polymorphisms were associated with changes of SDS-BMI or sOB-R concentrations in children after therapy. Carriers of the wild-type K665N and at least one minor Q223R allele had the greatest likelihood of losing weight (OR = 5.09, p = 0.006), an increase in sOB-R (ptrend = 0.022) and decrease in SDS-BMI correlated with the decrease of fat mass (p < 0.001). In contrast, carrying of the wild-type Q223R and at least one minor K665N allele were associated with a decrease in sOB-R concentrations and a decrease in SDS-BMI correlated with a decrease in fat-free mass (p = 0.002). We suggest that the combination of different LEPR variants, not a single variant, might determine predisposition to weight loss in the prepubertal period. PMID:27240401

    The metabolic syndrome is associated with insulin resistance, a systemic low-grade inflammatory state, and endothelial dysfunction. These disorders may arise at a very early age in obese children. The aim of this study was to confirm changes in endothelial dysfunction and inflammatory biomarkers in obese prepubertal children and to evaluate the effect of body mass index (BMI) modification on these biomarkers. Biomarkers for inflammation, endothelial dysfunction, and insulin resistance were measured in obese children (47) and healthy controls (47). Baseline pretreatment levels of insulin (P = .019), homeostasis model assessment of insulin resistance (P = .004), soluble intercellular adhesion molecule (sICAM) (P = .003), and C-reactive protein (CRP) (P < .001) were significantly higher in obese children than in controls. After 9 months of treatment, obese children with lowered BMI SD score (SDS-BMI) displayed a significant decrease in insulin (P = .011), homeostasis model assessment of insulin resistance (P = .012), CRP (P = .006), and interleukin-6 (IL-6) (P = .045) levels compared with obese children with stable SDS-BMI; they also displayed a nonsignificant drop in sICAM levels. Similarly, obese children with lowered SDS-BMI displayed a decrease in CRP (P = .005) and IL-6 (P = .065) compared with baseline levels before treatment. In the total obese group, changes in SDS-BMI correlated positively with changes in CRP (P = .035), IL-6 (P = .027), and sICAM-1 (P = .038) levels. Only SDS-BMI was an independent predictive factor for CRP (P = .031), IL-6 (P = .027), and sICAM-1 (P = .033). Prepubertal obese children displayed alterations indicative of endothelial dysfunction, insulin resistance, and inflammatory state. Lowering of the SDS-BMI after 9 months of treatment was associated with an improvement in these variables compared with those in obese children with stable SDS-BMI status.

    Childhood obesity is commonly associated with early signs of endothelial dysfunction, characterized by impairment of insulin signaling and vascular Nitric Oxide (NO) availability. However, the underlying mechanisms remain to be established. Hence, we tested the hypothesis that endothelial insulin-stimulated NO production and availability was impaired and related to Endoplasmic Reticulum (ER) in human umbilical vein endothelial cells (HUVECs) cultured with plasma obtained from pre-pubertal obese (OB) children. OB children (N = 28, age: 8.8 ± 2.2; BMI z-score: 2.15 ± 0.39) showed impaired fasting glucose, insulin and HOMA-IR than normal weight children (CTRL; N = 28, age: 8.8 ± 1.7; BMI z-score: 0.17 ± 0.96). The in vitro experiments showed that OB-plasma significantly impaired endothelial insulin-stimulated NO production and bioavailability compared to CTRL-plasma. In parallel, in HUVECs OB-plasma increased GRP78 and activated PERK, eIF2α, IkBα and ATF6 (all ER stress markers). Moreover, OB-plasma increased NF-κB activation and its nuclear translocation. Notably, all these effects proved to be significantly restored by using PBA and TUDCA, known ER stress inhibitors. Our study demonstrate for the first time that plasma from obese children is able to induce in vitro endothelial insulin resistance, which is characterized by reduced insulin-stimulated NO production and bioavailability, endothelial ER stress and increased NF-κB activation.

    Although it is known that obesity, diabetes, and Kawasaki's disease play important roles in systemic inflammation and in the development of both endothelial dysfunction and cardiomyopathy, there is a lack of data regarding the endothelial function of pre-pubertal children suffering from cardiomyopathy. In this study, we performed a systematic review of the literature on pre-pubertal children at risk of developing cardiomyopathy to assess the endothelial function of pre-pubertal children at risk of developing cardiomyopathy. We searched the published literature indexed in PubMed, Bireme and SciELO using the keywords ‘endothelial', ‘children', ‘pediatric' and ‘infant' and then compiled a systematic review. The end points were age, the pubertal stage, sex differences, the method used for the endothelial evaluation and the endothelial values themselves. No studies on children with cardiomyopathy were found. Only 11 papers were selected for our complete analysis, where these included reports on the flow-mediated percentage dilatation, the values of which were 9.80±1.80, 5.90±1.29, 4.50±0.70, and 7.10±1.27 for healthy, obese, diabetic and pre-pubertal children with Kawasaki's disease, respectively. There was no significant difference in the dilatation, independent of the endothelium, either among the groups or between the genders for both of the measurements in children; similar results have been found in adolescents and adults. The endothelial function in cardiomyopathic children remains unclear because of the lack of data; nevertheless, the known dysfunctions in children with obesity, type 1 diabetes and Kawasaki's disease may influence the severity of the cardiovascular symptoms, the prognosis, and the mortality rate. The results of this study encourage future research into the consequences of endothelial dysfunction in pre-pubertal children. PMID:22473410

    Omentin-1 is a recently recognized adipokine primarily originating in visceral adipose tissue. We posited that circulating omentin-1 could be an early marker of metabolic dysfunction. To this end, we examined the associations between circulating omentin-1, body fat (bioelectric impedance), an endocrine-metabolic profile (homeostasis model assessment for insulin resistance (HOMA(IR)), serum lipids, high-molecular-weight (HMW) adiponectin and blood pressure (BP)) and family history of obesity and diabetes in asymptomatic prepubertal children (n = 161; 77 boys and 84 girls; age 7 ± 1 year) with a normal distribution of height and weight. Increased circulating omentin-1 was associated with a poorer metabolic profile, with relatively higher HOMA(IR), fasting triacylglycerol, BP and familial prevalence of diabetes (all P < 0.005 to P < 0.0001), and relatively lower fraction of HMW adiponectin (P < 0.005), whereas no relationship was found with body weight or fat or with family history of obesity. All these associations were independent of age, gender and fat mass. In conclusion, circulating omentin-1 may become a marker of metabolic dysfunction integrating insulin sensitivity, markers of adipose-tissue metabolism and BP as early as in prepubertal childhood.

    Summary Background In the past decades, the obesity epidemic in children of all ages has been an important research field for detecting the metabolic causes and consequences of obesity, the major focus being on insulin and adipocytokine levels. Metabolic work-up in obese children is recommended in the age group as young as 2–6 years. There is evidence that birth weight can be a factor causing obesity later in life accompanied by metabolic complications. Methods Insulin, leptin, and adiponectin levels were analyzed in 269 obese children and 60 controls, as well as 110 newborn children with different birth weight and different length of gestation, using standard methods. Results In 53.6% of the obese children, complications of obesity such as diabetes mellitus, obesity, hyperlipidemia, heart attack or stroke were found in family members. The peak insulinemia on OGTT was significantly higher in the pubertal compared to the prepubertal group (110.5± 75.9 μU/mL versus 72.2±62.7 μU/mL) (p<0.005). Glucose intolerance was confirmed in 24%. The leptin level was significantly higher and the adiponectin level was lower in pubertal obese children compared to the prepubertal children and controls (p<0.05). In newborns the leptin and adiponectin levels were in correlation with anthropometric parameters: body weight (BW), body length (BL), BW/BL, BMI, and the pondered index (p<0.05). Conclusion Obese children have high insulinemia in all ages, reaching its peak towards puberty. The leptin and adiponectin levels might be indicators of the metabolic syndrome. Our findings in newborns might influence the nutritional approach in the future in order to prevent complications of obesity. PMID:28356821

    Childhood studies of the fat-bone relationship are conflicting, possibly reflecting the influence of metabolic abnormalities in some but not all obese children. Bone mass was compared between prepubertal overweight children with (n=41) and without (n=99) pre-diabetes. Associations of bone mass with measures of total and central adiposity, glucose intolerance, insulin sensitivity, lipid profile, systemic inflammation, and osteocalcin were also determined. In 140 overweight children aged 7–11 y, an oral glucose tolerance test was used to identify those with pre-diabetes and for determination of glucose, 2-h glucose, glucose AUC, insulin, 2-hr insulin, and insulin AUC. Blood samples were also assessed for lipids, C-reactive protein, and osteocalcin. Total body bone mineral content (BMC), fat-free soft tissue mass (FFST), and fat mass (FM) were measured by DXA. Visceral adipose tissue (VAT) and subcutaneous abdominal adipose tissue (SAAT) were assessed using MRI. Total body BMC was 4% lower in overweight children with pre-diabetes than those without pre-diabetes, after controlling for sex, race, height, and weight (P=0.03). In the total sample, FM was positively related with BMC (β=0.16, P=0.01), after adjusting for sex, race, height, and FFST. However, VAT (β=−0.13, P=0.03) and SAAT (β=−0.34, P=0.02) were inversely associated with BMC, after controlling for sex, race, height, FFST, FM, and SAAT or VAT. No significant associations were found between BMC and the biochemical measurements. Prepubertal overweight children with pre-diabetes may be at risk for poor skeletal development. In addition, it appears that greater levels of central, rather than total, adiposity may be deleterious for developing bone. PMID:20641032

    The prevalence of sustaining a fall is particularly high in children. Deficits in postural control and muscle strength are important intrinsic fall risk factors. Thus, the purpose of this study was to investigate the impact of balance training (BT) followed by detraining on postural control, plantar flexor strength, and jumping height in prepubertal children. Thirty grade 1 school children participated in this study and were assigned to either an intervention class (INT, n = 15, age 6.7 ± 0.5 years) or a control class (n = 15, age 6.6 ± 0.5 years). The INT participated in 4 weeks of BT (3 per week) integrated in their physical education lessons. Pre, post, and follow-up tests included the measurements of postural sway on a balance platform, maximal torque and rate of force development of the plantar flexors on an isokinetic device, and jumping height on a force platform. The significance level was set at p < 0.05. Balance training resulted in tendencies in terms of small to medium interaction effects yet not statistically significant improvements in postural sway (f = 0.14; p > 0.05), force production of the plantar flexors (f = 0.18; p> 0.05), and jumping height (f = 0.25; p> 0.05). Immaturity of the postural control system and deficits in attentional focus during practice of balance exercises could be responsible for the nonsignificant findings in this study. Thus, other training regimen (e.g., resistance training) should be applied alone or in combination with BT, which may have the potential to promote balance and strength in children.

    Susceptibility to environmental stressors has been described for fetal and early childhood development. However, the possible susceptibility of the prepubertal period, characterized by the orchestration of the organism towards sexual maturation and adulthood has been poorly investigated and exposure data are scarce. In the current study levels of cadmium (Cd), cotinine and creatinine in urine were analyzed in a subsample 216 children from 12 European countries within the DEMOCOPHES project. The children were divided into six age–sex groups: boys (6–8 years, 9–10 years and 11 years old), and girls (6–7 years, 8–9 years, 10–11 years). The number of subjects per group was between 23 and 53. The cut off values were set at 0.1 µg/L for Cd, and 0.8 µg/L for cotinine defined according to the highest limit of quantification. The levels of Cd and cotinine were adjusted for creatinine level. In the total subsample group, the median level of Cd was 0.180 µg/L (range 0.10–0.69 µg/L), and for cotinine the median wet weight value was 1.50 µg/L (range 0.80–39.91 µg/L). There was no significant difference in creatinine and cotinine levels between genders and age groups. There was a significant correlation between levels of cadmium and creatinine in all children of both genders. This shows that even at such low levels the possible effect of cadmium on kidney function was present and measurable. An increase in Cd levels was evident with age. Cadmium levels were significantly different between 6–7 year old girls, 11 year old boys and 10–11 year old girls. As there was a balanced distribution in the number of subjects from countries included in the study, bias due to data clustering was not probable. The impact of low Cd levels on kidney function and gender differences in Cd levels needs further investigation. - Highlights: • In 216 children from 6 to 11 years old the median level of Cd was 0.18 µg/L. • The median level of cotinine was 1.50 µg/L.

    Body fat distribution determines obesity-related morbidity in adults but little is known of the aetiology or pathophysiology in children. This study investigates differences in insulin-mediated metabolism in primary cell cultures of subcutaneous and visceral preadipocytes derived from prepubertal children. The impact of differentiation and responses to TNF{alpha} exposure was also investigated. Proliferation rates were greater in subcutaneous versus visceral preadipocytes (41 h(3) versus 69 h(4); P = 0.008). Insulin caused a dose-dependent increase in GSK-3 phosphorylation and an increase in MAPK phosphorylation over time, with increased sensitivity in subcutaneous preadipocytes. Post-differentiation, dose-dependent increases in GSK-3 phosphorylation were maintained, while MAPK phosphorylation was identical in both subtypes. No changes were observed in insulin receptor abundance pre-/post-differentiation. GLUT4 abundance was significantly increased in visceral versus subcutaneous adipocytes by 76(4)%; P = 0.03), coincidental with increased insulin-stimulated 2-deoxy-glucose transport (+150(26)% versus +79(10)%; P = 0.014) and further elevated by acute exposure to TNF{alpha} (+230(52)%; P = 0.019 versus +123(24)%; P = 0.025, respectively). TNF{alpha} also significantly increased basal glucose transport rates (+44(14)%; P = 0.006 versus +34(11)%; P = 0.007) and GLUT1 localisation to the plasma membrane. These data establish site-specific differences in subcutaneous and visceral fat cells from children. Responses to insulin varied with differentiation and TNF{alpha} exposure in the two depots, consistent with parallel changes in GLUT1/4 abundance and localisation.

    Background: Obese children are subject to the same chronic oxidative and inflammatory stress, responsible for the onset of all the complications typical of adult age, such as insulin resistance, type 2 diabetes, dyslipidemia and cardiovascular disease. Objectives: Since few studies are reported in prepubertal obese children, we investigated the relationship between oxidative stress, body composition and metabolic pattern in childhood obesity in comparison with adult obese patients. Methods: We enrolled 25 prepubertal children (12 males and 13 females) aged 5-12 years with a mean value of standard deviation of BMI (SDS-BMI)±SEM of 1.96±0.09. We performed oral glucose tolerance test, hormonal and metabolic evaluation, bioimpedentiometry, evaluation of total antioxidant capacity using spectroscopical method using a radical cation, 2,2(I)- azinobis(3-ethylbenzothiazoline-6 sulphonate) (ABTS), as indicator of radical formation, with a latency time (LAG) proportional to antioxidant in the sample. Results: LAG values significantly correlate with % fat mass, waist circumference and waist/hip ratio. However mean LAG values were significantly lower than in obese adults. Conclusions: We suggest that children are more susceptible to oxidative stress than adults, possibly to incomplete development of antioxidant system. Prognostic and therapeutical implications need to be further investigated.

    To examine differences in growth and metabolism in prepubertal children born early term, full term, and late term. We retrospectively studied 294 prepubertal children aged 7.3 years (range 3.0-12.1 years). Children were separated into those born early term (37 0/7-38 6/7 weeks of gestation; n = 68), full term (39 0/7-40 6/7 weeks; n = 179), and late term (41 0/7-41 6/7 weeks; n = 47). Clinical assessments included anthropometry, DXA-derived body composition, fasting lipids, and glucose homeostasis. Statistical models accounted for important confounding factors, such as gender, age, birth weight SDS, birth order, and parental variables. When birth weight was adjusted for sex and gestational age (birth weight SDS), late terms were heavier than both early (p = 0.034) and full (p = 0.020) terms. Early term children were shorter than both full (p = 0.010) and late (p = 0.049) term children, but differences in height disappeared following correction for parents' heights. There were no differences in glucose homeostasis, BMI SDS, adiposity, or fat distribution between groups. Lipid profiles were also similar. When important confounding factors were accounted for, there were no meaningful differences in anthropometry, glucose homeostasis, and lipid profile among children born early term, full term, or late term.

    Background: Urethroplasty in pediatric patients is a challenging task. In this study, we have tried to assess the complexity and evaluate the outcome of progressive perineal anastomotic urethroplasty in prepubertal children. Materials and Methods: Retrospective data of all the prepubertal children who underwent progressive perineal urethroplasty between March 2009 and April 2014 were analyzed. Patients were evaluated with history, examination, essential laboratory investigations, retrograde urethrogram, and voiding cystourethrogram. Before subjecting the patients for definitive surgery, antegrade and retrograde endoscopic assessment was done. The surgery was performed by the transperineal route with the help of ×2.5 magnification. Patients were followed up with uroflowmetry for every 3 months in the 1st year and for every 6 months in the subsequent years. Results: Mean age of the patients was 7.3 (range 5–11) years. Mean urethral distraction defect was 1.7 (range 1–2.5) cm. All the patients were successfully managed by the perineal approach. Crural separation was performed in all the patients while additional inferior pubectomy was required in six patients. Mean operating time was 298 (range 180–400) min. Mean blood loss was 174 (range 100–500) ml. One patient had the left calf hematoma in the immediate postoperative period. Seven out of nine (77.7%) patients had successful urethroplasty. Two patients had failed urethroplasty who were successfully managed by redo-urethroplasty. Transient incontinence was observed in one patient. Erectile function could not be assessed in these patients. Conclusion: This study shows the feasibility of progressive perineal urethroplasty by the perineal route in prepubertal children. An endoscopic assessment should be performed before the definitive surgery. Use of loupe helps in performing better anastomosis and hence yielding a better result. PMID:28082772

    Worldwide, obesity trends are causing serious public health concern and in many countries threatening the viability of basic health care delivery. It is an independent risk factor for cardiovascular diseases and significantly increases the risk of morbidity and mortality. The last two decades have witnessed an increase in health care costs due to obesity and related issues among children and adolescents. Childhood obesity is a global phenomenon affecting all socio-economic groups, irrespective of age, sex or ethnicity. Aetiopathogenesis of childhood obesity is multi-factorial and includes genetic, neuroendocrine, metabolic, psychological, environmental and socio-cultural factors. Many co-morbid conditions like metabolic, cardiovascular, psychological, orthopaedic, neurological, hepatic, pulmonary and renal disorders are seen in association with childhood obesity. The treatment of overweight and obesity in children and adolescents requires a multidisciplinary, multi-phase approach, which includes dietary management, physical activity enhancement, restriction of sedentary behaviour, pharmacotherapy and bariatric surgery. A holistic approach to tackle the childhood obesity epidemic needs a collection of activities including influencing policy makers and legislation, mobilizing communities, restructuring organizational practices, establishing coalitions and networks, empowering providers, imparting community education as well as enriching and reinforcing individual awareness and skills. The implications of this global phenomenon on future generations will be serious unless appropriate action is taken.

    There is increasing evidence that cortisol contributes to cardiovascular risk. It is unclear whether physiological concentrations of serum cortisol are related to vascular risk markers in children. The cross-sectional associations between morning serum cortisol and cardiovascular risk markers: blood pressure (BP) and carotid intima-media thickness (IMT), were examined in a sample of healthy prepubertal children (age, 6.8 ± 0.1 y) attending primary care clinics. Serum cortisol was associated with increased systolic BP (SBP; n = 223; p < 0.001) and carotid IMT (n = 91; p < 0.0001). These associations were independent from age, BMI, body fat, waist, insulin resistance, serum lipids, and heart rate (HR). No gender interactions were apparent in these associations. In summary, a higher morning serum cortisol within the physiological range is in prepubertal children associated with vascular risk markers. Because childhood risk factors predict adult risk for cardiovascular disease, these observations may have implications in the prevention of cardiovascular disease early in life.

    Context: Ghrelin and peptide YY (PYY) are two hormones produced by the gastrointestinal tract that have effects on appetite. However, little is known about their secretion in response to meals high in individual macronutrients in prepubertal children. Objective: We sought to understand how meals high in carbohydrate, protein, and fat affect serum concentrations of total ghrelin and total PYY, hypothesizing that these macronutrients would exert differential effects on their secretion. Design and Setting: This was a cross-sectional study at one tertiary care center. Subjects: Subjects were 7- to 11-yr-old healthy normal-weight (NW) and obese (OB) volunteers recruited from local advertisements. Interventions: After an overnight fast, the subjects were given a breakfast high in carbohydrate, protein, or fat at 0800 h. Blood samples for total ghrelin and total PYY were taken at baseline, 30 min, and hourly from 0900 to 1200 h. Main Outcome Measure: We assessed postprandial ghrelin suppression and PYY elevation, as well as changes in reported hunger and satiety, after the three test meals. Results: After the high-protein meal, ghrelin declined gradually in both groups over the study period without subsequent increase, whereas ghrelin suppressed more rapidly to a nadir at 60 min after the high-carbohydrate meal in both NW and OB children, followed by rebound in ghrelin levels. Similarly, after the high-protein meal, PYY concentrations increased steadily over the course of the morning in both groups without decline, whereas PYY levels peaked 30 min after the high-carbohydrate meal in both NW and OB subjects with significant decline thereafter. Ghrelin and PYY responses to the high-fat meal were somewhat intermediate between that observed with high carbohydrate and high protein. The OB children reported higher hunger and lower satiety after the high-carbohydrate meal compared to the NW subjects, whereas appetite ratings were similar between the groups after the high

    The prevalence of childhood overweight and obesity continues to be unacceptably high and of public health concern in Europe. During childhood and adolescence, environmental factors are the main drivers of obesity development. Obesity is caused by a chronic energy imbalance involving both dietary intake and physical activity patterns. Several risk factors are influencing obesity development, even starting in the prenatal period. From birth, along life, mainly diet and physical activity/inactivity are the most important drivers on top of genetic susceptibility. The first years of life can therefore be crucial to start preventive interventions that can have an impact on lifestyle and on later overweight and obesity. Schools are an attractive and popular setting for implementing interventions for children. Interventions including a community component are considered to be the most effective. Obesity control will require policy interventions to improve the environments that promote poor dietary intake and physical inactivity rather than individually focused interventions. More solid institutional and health policies are needed together with more effective interventions to obtain evident changes for the prevention of excess adiposity among children.

    Thirty-six prepubertal inpatients were videotaped completing five stories thematically related to attachment experiences and classified by their attachment representations. Children also completed the Children's Depression Inventory and Diagnostic Interview for Children and Adolescents-Revised. Mothers completed demographic questionnaires. Percentage of secure (B) attachment was only about one tenth of the normative percentage, anxious-ambivalent (C) attachment was between two and three times the normative percentage, and disorganized (D) attachment was almost twice the normative percentage. Both D attachment and the total number of disorganized story responses were associated with negative self-esteem and clinical-range depression. Anxious-avoidant (A) attachment decreased the likelihood, while C and D attachment increased the likelihood, of separation anxiety disorder. Clinical intervention needs to focus on the meaning of parental relationships represented in the child's mind, specifically the negative self-esteem and separation anxiety associated with the lack of felt security provided by the parents.

    The influence of levetiracetam (LEV) and valproic acid (VPA) monotherapy on sex-steroid hormone profile was investigated in thirty prepubertal children. VPA-treated children showed greatest androstendione concentrations when compared to LEV treated children (p=0.016) and to controls (p=0.011). All other reproductive endocrine hormones were similar among groups. In conclusion, LEV does not seem to induce changes in reproductive endocrine functions as well as clinically relevant endocrine side effects in prepubertal children.

    Children develop lower levels of muscle force, and at slower rates, than adults. Although strength training in children is expected to reduce this differential, a synchronous adaptation in the tendon must be achieved to ensure forces continue to be transmitted to the skeleton with efficiency while minimizing the risk of strain-related tendon injury. We hypothesized that resistance training (RT) would alter tendon mechanical properties in children concomitantly with changes in force production characteristics. Twenty prepubertal children (age 8.9 ± 0.3 yr) were equally divided into control (nontraining) and experimental (training) groups. The training group completed a 10-wk RT intervention consisting of 2-3 sets of 8-15 plantar flexion contractions performed twice weekly on a recumbent calf-raise machine. Achilles tendon properties (cross-sectional area, elongation, stress, strain, stiffness, and Young's modulus), electromechanical delay (EMD; time between the onset of muscle activity and force), rate of force development (RFD; slope of the force-time curve), and rate of electromyographic (EMG) increase (REI; slope of the EMG time curve) were measured before and after RT. Tendon stiffness and Young's modulus increased significantly after RT in the experimental group only (∼29% and ∼25%, respectively); all other tendon properties were not significantly altered, although there were mean decreases in both peak tendon strain and strain at a given force level (14% and 24%, respectively; not significant) which may have implications for tendon injury risk and muscle fiber mechanics. A decrease of ∼13% in EMD was found after RT for the experimental group, which paralleled the increase in tendon stiffness (r = -0.59); however, RFD and REI were unchanged. The present data show that the Achilles tendon adapts to RT in prepubertal children and is paralleled by a change in EMD, although the magnitude of this change did not appear to be sufficient to influence RFD.

    A 2-night polysomnographic study of 9 rigorously assessed prepubertal children who fit Diagnostic Statistical Manual-III criteria for attention deficit disorder with hyperactivity (ADDH) and a contrast group of 11 control children is reported. Despite the fact that 57% of the ADDH group were reported to experience restless sleep on structured parental rating forms, they did not show any sleep architecture abnormalities on polysomnographic recordings when compared with the normals at baseline other than decreased rapid eye movement (REM) activity. Seven of the ADDH boys were restudied after 6 months of continuous methylphenidate therapy (mean daily dose of 34.4 +/- 14.0 mg or 1.4 +/- 0.7 mg/kg). Across and within (pre-post) group comparisons showed that methylphenidate therapy was associated with delayed sleep onset, lengthened sleep, and changes in certain REM sleep variables.

    Vitamin K contributes to bone health, probably through its role as cofactor in the carboxylation of osteocalcin. Intervention studies in adults have demonstrated that markedly higher osteocalcin carboxylation is obtained by intakes of vitamin K well above the current recommended dietary intake. However, the relationship between increased vitamin K2 intake and enhanced osteocalcin carboxylation has never been shown in healthy children. The objective was to study the effect of 45 microg menaquinone-7 (MK-7; one of the vitamin K2 species) on the circulating levels of undercarboxylated osteocalcin (ucOC) and carboxylated osteocalcin (cOC) in healthy prepubertal children. We hypothesised that MK-7 supplementation will reduce the ucOC:cOC ratio (UCR), indicating an improved vitamin K status. The present study is a double-blind randomised placebo-controlled trial examining the effect of 8 weeks MK-7 supplementation on the carboxylation of osteocalcin in healthy children (n 55). Serum levels of ucOC, cOC and MK-7 were measured at baseline and after 8 weeks, together with bone markers and coagulation parameters. The UCR was used as an indicator of vitamin K status. In the MK-7-supplemented group (n 28), the circulating concentration of inactive ucOC reduced and the UCR improved whereas the concentration of MK-7 increased. Within the placebo group, ucOC, cOC, UCR and MK-7 did not significantly change over time. In both groups, bone markers and coagulation parameters remained constant over time. These findings demonstrate that in healthy, prepubertal children, modest supplementation with MK-7 increases circulating concentrations of MK-7 and increases osteocalcin carboxylation.

    Customarily, speaking and singing have tended to be regarded as two completely separate sets of behaviors in clinical and educational settings. The treatment of speech and voice disorders has focused on the client's speaking ability, as this is perceived to be the main vocal behavior of concern. However, according to a broader voice-science perspective, given that the same vocal structure is used for speaking and singing, it may be possible to include singing in speech and voice therapy. In this article, a theoretical framework is proposed that indicates possible benefits from the inclusion of singing in such therapeutic settings. Based on a literature review, it is demonstrated theoretically why singing activities can potentially be exploited in the treatment of prepubertal children suffering from speech and voice disorders. Based on this theoretical framework, implications for further empirical research and practice are suggested.

    Tissue damage resulting from oxidative stress induced by a pathological condition might have more serious consequences in children than in adults. Researchers have not yet identified particular markers - alone or in combination with others - of oxidative stress, or their role in pediatric diseases. The aim of this study was to identify gender-based biomarkers for measuring oxidative stress. Oxidative biomarkers were studied in 138 healthy Spanish children (85 boys, 53 girls) 7 to 12 years of age, at the prepubertal (Tanner I) stage, independent of body mass index (BMI), age, fitness (measured by 20-m shuttle run test), and physical activity (measured by participation in an after-school exercise program). The oxidative biomarkers measured were lipid peroxidation products, total nitrites, protein carbonyls, and oxidized glutathione (GSSG). The antioxidant biomarkers measured were total glutathione (TG), reduced glutathione (GSH), superoxide dismutase activity (SOD), and glutathione peroxidase activity. In the study population, height, weight, waist circumference, and BMI were lower in girls than in boys. For oxidative biomarkers, boys had higher levels of protein carbonyl than girls (p < 0.001). In spite of this, girls had higher levels of GSSG (p < 0.001) and TG (p = 0.001), and a lower GSH/GSSG ratio (p < 0.001) than boys. For the antioxidant response, girls had higher levels of SOD (p = 0.002) than boys. All analyses were adjusted for BMI, age, fitness, and physical activity. In conclusion, prepubertal girls had higher oxidative stress than boys, in addition to higher levels of SOD, independent of age, BMI, fitness, and physical activity.

    Malnutrition can lead to possible irreversible consequences in the development of muscle function and some of them are yet poorly characterized. The present study evaluated the mechanical properties of the triceps surae and motor performance in stunted (S) and eutrophic (E) prepubertal children (9 years ± 6 months). Height-for-age ratio was used as indicator of stunting due to early malnutrition, according to the World Health Organization. Torque was determined by maximal voluntary contractions (MVC) and musculotendinous (MT) stiffness was achieved through quick-release tests to obtain MT stiffness index (SI(MT)) and passive stiffness (K (p)) from linear MT stiffness-torque relationships. Percutaneous supramaximal electrically elicited contractions determined twitch torque (Pt) and electromechanical delay (EMD). Motor performance was evaluated by balance test. S group presented significantly lower MVC and a trend of lower Pt values indicating lower capacities to develop force under voluntary or induced conditions. Significantly higher SI(MT) and EMD values were observed, while K (p) and motor performance in balance were significantly lower. Higher SI(MT) values have been reported previously in youngest prepubertal children, indicating that immature activation capacities can mask MT stiffness assessment during voluntary contractions, taking into consideration the higher EMD values as a measure of muscle stiffness contribution. Lower K (p) may indicate a delay in the maturation of tendinous tissue in S group, influencing motor performance in balance. The present study shows that malnutrition leads to adaptation of intrinsic MT elastic properties, but depends on the level of the observed structure.

    Open-label buspirone was studied in 25 prepubertal psychiatric inpatients (age 8.0 +/- 1.8 years, 76% boys) presenting with anxiety symptoms and moderately aggressive behavior. Patients with severe aggression, requiring rapid treatment with mood stabilizers or neuroleptics, were excluded. A 3-week titration (maximum 50 mg daily) preceded a 6-week maintenance phase at optimal dose. Buspirone was discontinued in 6 children (25%): 4 developed increased aggression and agitation, and 2 developed euphoric mania. For the 19 patients who completed the study, mean optimal dose was 28 mg daily. Among completers, depressive symptoms were reduced 52% by Week 6 on Children's Depression Inventory (p < or = 0.001). Decreased aggressivity was reflected in a 29% reduction on Measure of Aggression, Violence, and Rage in Children [MAVRIC] ratings (p < or = 0.02) and in 86% less time in seclusion or physical restraints (p < or = 0.02). Clinical Global Assessment scores improved (CGAS 41 vs. 54, p < or = 0.01). Only 3 children improved sufficiently to continue buspirone after the study. Residual aggressivity and global functioning remained problematic. Buspirone may pose behavioral risks in treating moderate aggressivity in 24% of children with anxiety; in the others, the therapeutic effects on aggression, anxiety, and depression were limited but significant.

    Objective To assess associations between adiposity and hippocampal-dependent and hippocampal-independent memory forms among prepubertal children. Study design Prepubertal children (7–9-year-olds, n = 126), classified as non-overweight (<85th %tile BMI-for-age [n = 73]) or overweight/obese (≥85th %tile BMI-for-age [n = 53]), completed relational (hippocampal-dependent) and item (hippocampal-independent) memory tasks, and performance was assessed with both direct (behavioral accuracy) and indirect (preferential disproportionate viewing [PDV]) measures. Adiposity (%whole body fat mass, subcutaneous abdominal adipose tissue, visceral adipose tissue, and total abdominal adipose tissue) was assessed using DXA. Backward regressions identified significant (P <0.05) predictive models of memory performance. Covariates included age, sex, pubertal timing, socioeconomic status, IQ, oxygen consumption (VO2max), and body mass index (BMI) z-score. Results Among overweight/obese children, total abdominal adipose tissue was a significant negative predictor of relational memory behavioral accuracy, and pubertal timing together with socioeconomic status jointly predicted the PDV measure of relational memory. In contrast, among non-overweight children, male sex predicted item memory behavioral accuracy, and a model consisting of socioeconomic status and BMI z-score jointly predicted the PDV measure of relational memory. Conclusions Regional, and not whole body, fat deposition was selectively and negatively associated with hippocampal-dependent relational memory among overweight/obese prepubertal children.

    Interest in childhood metabolic syndrome (MetS) has increased substantially due to the increasing prevalence of childhood obesity on a global scale. Early recognition of MetS is critical in order to delay the development of cardiovascular disease (CVD). In this study, we evaluated the relationship between complete blood count (CBC) parameters and MetS among pre-pubertal children which may provide evidence in support of using low cost, readily available clinical haematological parameters for the detection of MetS. A retrospective analysis was carried out on 330 (125 lean vs. 205 overweight) Turkish pre-pubertal children who attend to a paediatric outpatient clinic. Age, gender, puberty, body mass index, CBC parameters, cardiometabolic risk factors including lipid profiles, high sensitive serum reactive protein (hsCRP) and insulin resistance index calculated by homeostasis model assessment (HOMA-IR) were evaluated and compared among lean, overweight children and children with MetS. The mean age of the study population was 7.4 ± 1.9 years. In both gender, the mean values of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were significantly lower and red blood cell (RBC), platelet (PLT) counts were significantly higher in overweight children. Overall, 8.4% (n = 28) of patients met the criteria of MetS. Children with MetS had higher levels of PLT and lower levels of mean platelet volume (MPV). Of all the haematological parameters analysed, PLT was positively, whereas MPV was negatively correlated with MetS in girls. In addition, MPV was inversely correlated with fasting blood glucose, HOMA-IR, low density lipoprotein-cholesterol (LDL-C) and low density lipoprotein-cholesterol/high density lipoprotein-cholesterol (LDL-C/HDL-C) ratio in girls after adjusting for confounding factors. The risk analyses of MetS in terms of MPV quartiles showed that the adjusted OR (95% CI) for the lowest vs. the

    The aim of the study was to evaluate fasting levels of glucose, insulin, leptin, total ghrelin, and obestatin in a group of prepubescent obese children before and after weight loss. We enrolled 64 prepubescent obese children, but only 35 completed the study (mean age 7.6 +- 0.9 years, 19 females) and 20 normal-weight prepubescent children as controls. Fasting plasma concentration of glucose, insulin, Homeostasis Model assessment for insulin resistance (HOMA-IR), and leptin, total ghrelin, and obestatin levels were measured at baseline and after a 6-month lifestyle intervention (i.e. improved nutrition and increased physical activity). At baseline, obese children showed significantly (p less than 0.001) higher leptin and obestatin levels, and lower total ghrelin concentrations than control subjects. Weight loss significantly (p less than 0.001) diminished plasma leptin and insulin levels and increased ghrelin and obestatin concentrations. Weight loss in prepubescent children is associated with a significant change in leptin, ghrelin and obestatin concentrations. These results confirm the hypothesis that levels of these hormones are closely associated with obesity in childhood and might take part, as consequence but not as a cause, in glucose, fat, and energy metabolism.

    Gonadal inflammation (GI) is a common disease that may affect prepubertal boys. Neonates may suffer from bacterial infection due to congenital or aging processes affecting the urinary tract. This inflammatory process is also prevalent in prepubertal boys. However, in this group, the etiology, the needed imaging modalities and proper management have not yet been clearly defined. This manuscript will systematically review the various etiologies causing GI in pre-pubertal boys, discuss the proper imaging needed, and image interpretation and will provide treatment and follow-up recommendations.

    While the neuroprotective benefits of estrogen and progesterone in critical illness are well established, the data regarding the effects of androgens are conflicting. Surgical repair of congenital heart disease is associated with significant morbidity and mortality, but there are scant data regarding the postoperative metabolism of sex steroids in this setting. The objective of this prospective observational study was to compare the postoperative sex steroid patterns in pediatric patients undergoing major cardiac surgery (MCS) versus those undergoing less intensive non-cardiac surgery. Urinary excretion rates of estrogen, progesterone, and androgen metabolites (μg/mmol creatinine/m(2) body surface area) were determined in 24-h urine samples before and after surgery using gas chromatography-mass spectrometry in 29 children undergoing scheduled MCS and in 17 control children undergoing conventional non-cardiac surgery. Eight of the MCS patients had Down's syndrome. There were no significant differences in age, weight, or sex between the groups. Seven patients from the MCS group showed multi-organ dysfunction after surgery. Before surgery, the median concentrations of 17β-estradiol, pregnanediol, 5α-dihydrotestosterone (DHT), and dehydroepiandrosterone (DHEA) were (control/MCS) 0.1/0.1 (NS), 12.4/11.3 (NS), 4.7/4.4 (NS), and 2.9/1.1 (p=0.02). Postoperatively, the median delta 17β-estradiol, delta pregnanediol, delta DHT, and delta DHEA were (control/MCS) 0.2/6.4 (p=0.0002), -3.2/23.4 (p=0.013), -0.6/3.7 (p=0.0004), and 0.5/4.2 (p=0.004). Postoperative changes did not differ according to sex. We conclude that MCS, but not less intensive non-cardiac surgery, induced a distinct postoperative increase in sex steroid levels. These findings suggest that sex steroids have a role in postoperative metabolism following MCS in prepubertal children.

    Patients with beta-thalassemia major (beta-thalassemia) frequently have bone disorders of multifactorial etiology. We attempted to analyze the relationship between the bone mineral density ([BMD] measured by dual-photon absorptiometry) and auxanologic parameters, degree of siderosis, function of the growth hormone (GH)/insulin-like growth factor-I (IGF-I)/IGF-binding protein-3 (IGFBP3) axis, calcium-phosphate balance, parathyroid hormone (PTH), and cytokines (interleukin-1beta [IL-1] and tumor necrosis factor-alpha [TNF-alpha]) in 30 prepubertal children with beta-thalassemia major and 15 age-matched children with constitutional short stature (CSS), who have normal glucose tolerance and thyroid function. Children with beta-thalassemia had a significantly decreased BMD and mean BMD% for age and sex (0.75+/-0.24 g/cm2 and 71%+/-10%, respectively) versus children with CSS (1.06+/-0.3 g/cm2 and 92%+/-7%, respectively). Thalassemic patients had significantly lower circulating concentrations of IGF-I and IGFBP3 (49+/-21 ng/mL and 1.2+/-0.25 mg/L, respectively) compared with control children (153+/-42 ng/mL and 2.1+/-0.37 mg/L, respectively). The GH response to provocation by clonidine and glucagon was defective (peak GH < 7 microg/L) in 12 of the 30 thalassemic children. Serum concentrations of IL-1beta and TNF-alpha did not differ among the two study groups. Hypocalcemia was detected in five of the 30 thalassemic patients: hypoparathyroidism was diagnosed in two of the five and rickets in the other three. BMD was highly correlated with the circulating concentrations of IGF-I and IGFBP3, as well as with the auxanologic parameters (age, weight, height, height standard deviation score [HSDS], and body mass index [BMI]). It is suggested that increasing the circulating IGF-I concentration through aggressive nutritional therapy and/or GH/IGF-I therapy with supplementation with vitamin D and/or calcium might improve bone growth and mineralization and prevent the development of

    To investigate in prepubertal obese children (POC) the profile of chronic low-grade systemic inflammation (CLGSI) and its relation to homocysteinemia, 72 POC were evaluated for serum C-reactive protein (CRP) and amyloid A (SAA) levels, both markers of CLGSI, and plasma levels of total homocysteine (tHcy), an independent risk factor for adult atherosclerosis, in comparison to 42 prepubertal lean children (PLC). The main observations in POC were higher CRP levels compared to PLC, positive association of SAA levels to CRP levels, no association of CRP or SAA levels to tHcy levels. Thus, in POC, positively interrelated to each other, elevated CRP and unaltered SAA levels reveal a unique profile of the CLGSI, not explaining homocysteinemia-induced risk for future atherosclerosis.

    There is a lack of data on metabolic risk factors during pre-puberty, which is important for identifying the subgroups of youth, at whom early interventions should be targeted. In this study, we evaluated the prevalence of metabolic risk factors and its subsequent relations with dietary patterns in Korean pre-pubertal children through a cross-sectional sample (n = 1,008; boys = 513) of pre-pubertal children (aged 8-9 years) from a sub-study of the Korea Metabolic Syndrome Research Initiatives (KMSRI) in Seoul, Korea. Measures of anthropometry and blood pressure as well as fasting blood samples were used in the analysis. A three-day food records were collected. The metabolic syndrome was defined according to the age-adjusted National Cholesterol Education Program Adult Treatment Panel III guidelines. An added metabolic risk score was calculated for each subject by summing the quintile values of the five individual risk factors. Among the 5 risk components of metabolic syndrome, high waist circumference (WC) was the major factor (P < 0.001). A significant increasing trend of the added metabolic syndrome risk score was observed with the increase of WC (P (trend) < 0.001) among both genders. The cutoff point for high WC for pre-pubertal children was 61.3 cm for boys and 59.9 cm for girls. The prevalence of high triglyceride (TG) values was significantly higher in girls than it was in boys (P < 0.01). Girls in the highest quintile of balanced dietary pattern scores had lower TG values (P (trend) = 0.032) than did those in the lowest quintile. Moreover, girls in the highest quintile of western dietary pattern scores showed increasing trend for the added metabolic risk score (P (trend) = 0.026) compared with those in the lowest quintile. Adverse associations exist between western dietary patterns and the accumulation of metabolic risks among girls, not in boys, even during pre-puberty. PMID:23610607

    Background: Pediatric obesity is the most prevalent nutritional disorder in American children. The detrimental social, psychological, and physiological effects of obesity call for pediatricians to address this health concern. The literature demonstrates that clinicians are underreporting the diagnosis of obesity in the pediatric setting. The primary purpose of this study was to determine if pediatricians at one pediatrics clinic in the Ochsner Health System are documenting the presence of an overweight or obese body mass index (BMI) as a diagnosis in the medical record. A secondary purpose of this study was to determine the demographics of all pediatric patients in the Ochsner Health System to be used for program development. Methods: A retrospective medical record review was conducted. Records from April 1, 2012 to April 1, 2016, were reviewed for the presence of the diagnosis of BMI classified as obese or overweight. Results: We analyzed a total of 175,066 records in this study. Of these records, 1.32% documented a diagnosis of obesity, and 0.5% documented a BMI score indicating overweight. The percentages of patient visits that met the Centers for Disease Control and Prevention criteria to be classified as obese or overweight were 28.66% and 30.41%, respectively. The majority of our pediatric patients were male (51.76%), white (43.31%), and 5-12 years old (43.80%). Conclusion: This study demonstrates that pediatricians at Ochsner Health Center for Children are not diagnosing patients who have unhealthy BMI scores as overweight or obese. Interventions are needed to increase the identification of children who may benefit from receiving resources that encourage a healthy lifestyle and optimal weight maintenance. PMID:28331453

    Purpose of the study was to evaluate the effect of yoga training and detraining on physical performance measures in pre-pubertal (7-9 year old) school going children. Subjects were randomized to two groups - yoga group and Physical exercise (PE) group after the baseline assessment. All the subjects were assessed for strength, endurance, whole body endurance through 20 meter shuttle and physical fitness, at 3 time points - Baseline, 3 months Post intervention and 3 months after detraining. The results suggest that the improvement in the physical performance is largely by the increase in the respiratory muscle strength in the yoga group. In conclusion, the study presents the efficacy of yoga to improve strength, endurance, whole body endurance and aerobic capacity with 3 months of training in the pediatric group. However, the effect of the training does not last after 3 months detraining.

    Our aim was to determine the influence of weight reduction on total (T-) and high-molecular weight (HMW-) adiponectin in obese (OB) prepubertal children. Seventy OB prepubertal white patients were followed for 18 months and studied after reducing their BMI by 1 (n = 51) and 2 standard deviation scores (SDS) (n = 21) under conservative treatment, and 6 months after achieving weight loss (n = 44). Body composition dual-energy X-ray absorptiometry (DXA) and serum levels of T- and HMW-adiponectin, resistin, leptin, leptin soluble receptor (sOB-R), tumoral necrosis factor-α and interleukin-6 were determined. The control group consisted of 61 healthy prepubertal children. At diagnosis T-adiponectin was higher (P < 0.01; confidence interval (+0.04) - (+0.15)) and HMW-adiponectin lower (P < 0.001; confidence interval (-0.45) - (-0.21)) in OB children than in controls. A reduction in body fat increased T- and HMW-adiponectin and sOB-R (all P < 0.001) and decreased leptin (P < 0.001) and interleukin-6 levels (P < 0.05). After 6 months of sustained weight reduction a decrease in tumoral necrosis factor-α (P < 0.01) occurred, whereas weight recovery increased leptin (P < 0.001) and decreased T-adiponectin (P < 0.05). HMW-adiponectin levels negatively correlated with homeostasis model assessment (HOMA) index and BMI in the whole cohort (both P < 0.001), as did T-adiponectin levels and HOMA index in OB patients (P < 0.01), but neither T- nor HMW-adiponectin correlated with body fat content (BFC) in OB children. We conclude that the impairment of T- and HMW-adiponectin levels in childhood obesity is different to that in elder OB patients, showing closer relationship with carbohydrate metabolism parameters than with BFC, but increasing their levels after weight loss and in association with metabolic improvement.

    Global concern has been raised in recent years over adverse effects that may result from exposure to chemicals that may interfere with the endocrine system. A specific question is related to low-dose effects and long-term exposure consequences, especially for critical populations (foetus, new born, prepubertal children). In this context, we decided to focus our attention on steroid hormones as they are the most potent endocrine disrupters. Our general goal is to investigate whether the steroid intake through food may represent a risk for prepubertal children, from an endocrine disruption point of view, especially with regard to the corresponding endogenous production level in this target population. As a starting point, it was estimated that a (re)-evaluation of the endogenous production of natural estrogens for this population was necessary, on the basis of a very sensitive and specific confirmatory measurement technique (gas chromatography-tandem mass spectrometry or gas chromatography-high resolution mass spectrometry). Thus, a new ultra-sensitive approach for steroid trace measurement in biological samples was developed, which was mainly based on a specific derivatisation (pentafluorobenzyl derivative) and negative chemical ionisation (NCI). Preliminary results obtained by applying this method on plasma samples from healthy prepubertal children demonstrated that estradiol endogenous level in prepubertal children is unsurprisingly very low. Estrone was determined in almost all samples at concentration in the 2-70 ng L(-1) range while 17alpha and 17beta estradiol were quantified in only few samples at concentrations ranging from 2 to 6 ng L(-1). Exogenous contributions of estrogens will therefore constitute a relatively higher proportion of sex hormone activity in the immature child.

    Objective: To identify the association of dietary, socioeconomic factors, sedentary behaviors and maternal nutritional status with abdominal obesity in children. Methods: A cross-sectional study with household-based survey, in 36 randomly selected census tracts in the city of Santos, SP. 357 families were interviewed and questionnaires and anthropometric measurements were applied in mothers and their 3-10 years-old children. Assessment of abdominal obesity was made by maternal and child's waist circumference measurement; for classification used cut-off points proposed by World Health Organization (1998) and Taylor et al. (2000) were applied. The association between variables was performed by multiple logistic regression analysis. Results: 30.5% of children had abdominal obesity. Associations with children's and maternal nutritional status and high socioeconomic status were shown in the univariate analysis. In the regression model, children's body mass index for age (OR=93.7; 95%CI 39.3-223.3), female gender (OR=4.1; 95%CI 1.8-9.3) and maternal abdominal obesity (OR=2.7; 95%CI 1.2-6.0) were significantly associated with children's abdominal obesity, regardless of the socioeconomic status. Conclusions: Abdominal obesity in children seems to be associated with maternal nutritional status, other indicators of their own nutritional status and female gender. Intervention programs for control of childhood obesity and prevention of metabolic syndrome should consider the interaction of the nutritional status of mothers and their children. PMID:26298655

    Background There are no data on the metabolic consequences of post-term birth (≥42 weeks gestation). We hypothesized that post-term birth would adversely affect insulin sensitivity, as well as other metabolic parameters and body composition in childhood. Methods 77 healthy pre-pubertal children, born appropriate-for-gestational-age were studied in Auckland, New Zealand: 36 born post-term (18 boys) and 41 (27 boys) born at term (38–40 weeks gestation). Primary outcome was insulin sensitivity measured using intravenous glucose tolerance tests and Bergman’s minimal model. Other assessments included fasting hormone concentrations and lipid profiles, body composition from whole-body dual-energy X-ray absorptiometry, 24-hour ambulatory blood pressure monitoring, and inflammatory markers. Results Insulin sensitivity was 34% lower in post-term than in term children (7.7 vs. 11.6 x10-4·min-1·(mU/l); p<0.0001). There was a compensatory increase in acute insulin response among post-term children (418 vs 304 mU/l; p=0.037), who also displayed lower glucose effectiveness than those born at term (2.25 vs 3.11 x10-2·min-1; p=0.047). Post-term children not only had more body fat (p=0.014) and less fat-free mass (p=0.014), but also had increased central adiposity with more truncal fat (p=0.017) and greater android to gynoid fat ratio (p=0.007) compared to term controls. Further, post-term children displayed other markers of the metabolic syndrome: lower normal nocturnal systolic blood pressure dipping (p=0.027), lower adiponectin concentrations (p=0.005), as well as higher leptin (p=0.008) and uric acid (p=0.033) concentrations. Post-term boys (but not girls) also displayed a less favourable lipid profile, with higher total cholesterol (p=0.018) and LDL-C (p=0.006) concentrations, and total cholesterol to HDL-C ratio (p=0.048). Conclusions Post-term children have reduced insulin sensitivity and display a number of early markers of the metabolic syndrome. These findings

    Objective: To evaluate obese children and adolescents' retinol plasma levels and to correlate them with metabolic syndrome components. Methods: Cross-sectional study with 61 obese children and adolescents (body mass index Z score - ZBMI>+2). Pubertal development, arterial blood pressure, body weight and height for nutritional classification and waist circumference were obtained. A 15mL blood sample was collected (after a 12-hour fasting in a low luminosity room) for retinol determination (cut-off inadequate if <30µg/dL), lipid profile (HDL-c, LDL-c, and triglycerides), oral glucose tolerance test (fasting and 120 minutes) and for high sensitivity C-reactive protein. Spearman correlation and multiple linear regression were used in the statistical analysis. Results: Mean age was 10.7±2.7 years. There was a predominance of male gender 38/61 (62%) and pre-pubertal 35/61 (57%) subjects. The average plasmatic retinol was 48.5±18.6ug/dL. Retinol deficiency and severe obesity were observed in 6/61 (10%) and 36/61 (59%), respectively. Glucose level at 120 minutes was the independent and predictive variable of plasma retinol levels [β=-0.286 (95%CI -0.013 - -0.001)]. Conclusions: An independent and inverse association between plasma retinol levels and glucose tolerance was observed, suggesting an important contribution of this vitamin in the morbidities associated to obesity in children and adolescents.

    Synopsis The prevalence of childhood obesity has reached epidemic proportions in the US and many other parts of the world. With obesity comes a variety of adverse health outcomes and metabolic complications. The liver in particular seems to be significantly impacted by fat deposition in the presence of obesity. In this article we discuss several aspects of childhood obesity from epidemiology and associated metabolic complications, to management strategies and therapy with particular attention to the impact of obesity on the liver resulting in non-alcoholic or metabolic fatty liver disease. The deleterious effects of obesity on the liver and health overall can be significantly impacted by a culture that fosters sustained nutritional improvement and regular physical activity. Here we summarize the current evidence supporting pharmacologic, behavioral and dietary interventions for the management of obesity and fatty liver disease in children. PMID:24274876

    Objective: The autonomic nervous system is assumed to have a role in the pathophysiology of obesity. In this study, we evaluated the autonomic system by measuring heart rate variability (HRV) in obese children. Methods: Thirty-two obese and 30 healthy children (mean ages: 11.6±2.0 years and 11.0±2.9 years, respectively) were enrolled in the study. Obesity was defined as a body mass index higher than 97th percentile for age- and gender-specific reference values. All participants were free of any disease and none of them was receiving any medication. Twenty-four-hour ambulatory electrocardiographic recordings were obtained and the time-domain and frequency-domain indices of HRV were analyzed. The study group was evaluated with respect to insulin resistance by HOMA-IR values. Results: A significant decrease in calculated HRV variables was observed in obese children as compared to controls. The HRV alteration was found in both time-domain and frequency-domain parameters. The subgroup analysis of the study group revealed a significant decrease in all investigated HRV parameters in the insulin-resistant obese children compared to the non-insulin-resistant obese ones. Conclusions: Our results indicate that HRV is decreased in obese children, which implies parasympathetic withdrawal and sympathetic predominance. A marked decrease in HRV was observed in insulin-resistant obese children compared to their non-insulin-resistant counterparts. We propose that autonomic imbalance pertaining especially to insulin resistance may be involved in the pathogenesis of obesity in pediatric patients Conflict of interest:None declared. PMID:21750633

    This review seeks to provide a current overview of musculoskeletal pain in overweight and obese children. Databases searched were Academic Search Complete, CINAHL, Medline, Proquest Health and Medical Complete, Scopus, Google Scholar, SPORTDiscuss and Trove for studies published between 1 January 2000 and 30 December 2012. We used a broad definition of children within a 3- to 18-year age range. The search strategy included the following terms: obesity, morbid obesity, overweight, pain, musculoskeletal pain, child, adolescent, chronic pain, back pain, lower back pain, knee pain, hip pain, foot pain and pelvic pain. Two authors independently assessed each record, and any disagreement was resolved by the third author. Data were analysed using a narrative thematic approach owing to the heterogeneity of reported outcome measures. Ninety-seven records were initially identified using a variety of terms associated with children, obesity and musculoskeletal pain. Ten studies were included for thematic analysis when predetermined inclusion criteria were applied. Bone deformity and dysfunction, pain reporting and the impact of children being overweight or obese on physical activity, exercise and quality of life were the three themes identified from the literature. Chronic pain, obesity and a reduction in physical functioning and activity may contribute to a cycle of weight gain that affects a child's quality of life. Future studies are required to examine the sequela of overweight and obese children experiencing chronic musculoskeletal pain. PMID:24077005

    Obesity among children, adolescents and adults has emerged as one of the most serious public health concerns in the 21st century. The worldwide prevalence of childhood obesity has increased remarkably over the past 3 decades. The growing prevalence of childhood obesity has also led to appearance of obesity-related comorbid disease entities at an early age. Childhood obesity can adversely affect nearly every organ system and often causes serious consequences, including hypertension, dyslipidemia, insulin resistance, dysglycemia, fatty liver disease and psychosocial complications. It is also a major contributor to increasing healthcare expenditures. For all these reasons, it is important to prevent childhood obesity as well as to identify overweight and obese children at an early stage so they can begin treatment and attain and maintain a healthy weight. At present, pharmacotherapy options for treatment of pediatric obesity are very limited. Therefore, establishing a comprehensive management program that emphasizes appropriate nutrition, exercise and behavioral modification is crucial. The physician’s role should expand beyond the clinical setting to the community to serve as a role model and to advocate for prevention and early treatment of obesity. PMID:25241606

    The quality of the diet of obese children is poor. Eating habits may alter micronutrient status in obese patients. In this study, we determined the serum levels of selenium, zinc, vanadium, molybdenum, iron, copper, beryllium, boron, chromium, manganese, cobalt, silver, barium, aluminum, nickel, cadmium, mercury, and lead in obese Turkish children. Thirty-four obese and 33 healthy control subjects were enrolled in the study. Serum vanadium and cobalt levels of obese children were significantly lower than those of the control group (0.244 ± 0.0179 vs. 0.261 ± 0.012 μg/l, p < 0.001, and 0.14 ± 0.13 vs. 0.24 ± 0.15 μg/l, p = 0.011, respectively). There was no significant difference between groups regarding the other serum trace element levels. In conclusion, there may be alterations in the serum levels of trace elements in obese children and these alterations may have a role in the pathogenesis of obesity.

    Overweight and obesity in children and adolescents is a growing problem with an increasing number of patients presenting with comorbidities to pediatricians and orthopedic surgeons. This overview summarizes the most common orthopedic problems in overweight children and obesity and highlights the treatment options in addition to weight reduction and physiotherapy leaded activation. In early infancy a persitent genu varum may be seen as a sign of Blount disease. In the school ages flat feet or persistent knock-knees has a higher incidence in overweight children. The incidence for back pain and osteoporosis are related with overweight and obese. At puberty, the slipped capital epiphysis, which always needs a surgical management, is mostly related to overweight/obese. A symptomatic retroversion of the femur can cause discomfort and lead to a surgical therapy himself.

    The purpose of this study was to identify overeating phenotypes and their correlates in overweight and obese children. One hundred and seventeen treatment-seeking overweight and obese 8-12year-old children and their parents completed the study. Children completed an eating in the absence of hunger (EAH) paradigm, the Eating Disorder Examination interview, and measurements of height and weight. Parents and children completed questionnaires that evaluated satiety responsiveness, food responsiveness, negative affect eating, external eating and eating in the absence of hunger. Latent profile analysis was used to identify heterogeneity in overeating phenotypes in the child participants. Latent classes were then compared on measures of demographics, obesity status and nutritional intake. Three latent classes of overweight and obese children were identified: High Satiety Responsive, High Food Responsive, and Moderate Satiety and Food Responsive. Results indicated that the High Food Responsive group had higher BMI and BMI-Z scores compared to the High Satiety Responsive group. No differences were found among classes in demographics or nutritional intake. This study identified three overeating phenotypes, supporting the heterogeneity of eating patterns associated with overweight and obesity in treatment-seeking children. These finding suggest that these phenotypes can potentially be used to identify high risk groups, inform prevention and intervention targets, and develop specific treatments for these behavioral phenotypes.

    Background The prevalence of lipoatrophy in children on antiretroviral therapy in Southern Africa is high, affecting around a third of children. Early diagnosis of lipoatrophy is essential for effective intervention to arrest progression. Methods Pre-pubertal children on antiretroviral therapy were recruited from a hospital-based family HIV clinic in Cape Town and followed up prospectively. Lipoatrophy was identified and graded by consensus between two HIV pediatricians. A dietician performed anthropometric measurements of trunk and limb fat. Anthropometric measurements in children with and without lipoatrophy were compared using multivariable linear regression adjusting for age and gender. The most discerning anthropometric indicators of lipoatrophy underwent Receiver Operating Characteristic curve analysis. The precision of anthropometric measurements performed by an inexperienced healthcare worker was compared to a research dietician. Results 36/100 recruits had lipoatrophy at baseline and a further 9 developed lipoatrophy by 15 month follow-up. Annual incidence of lipoatrophy was 12% (CI: 5–20%) per person-year of follow-up. A biceps skin-fold thickness <5mm at baseline had a sensitivity of 89% (CI: 67–100%) and a specificity of 60% (CI: 46–75%) for predicting which children would go on to develop lipoatrophy by 15 month follow-up. Negative and positive predictive values were 97% (CI: 91–100%) and 32% (CI: 14–50%). Conclusion Biceps skin-fold thickness <5mm in pre-pubertal children exposed to thymidine analogue-based antiretroviral therapy may be a useful screening tool to identify children who are likely to go on to develop lipoatrophy. The variation in precision of measurements performed by an inexperienced healthcare worker only marginally impacted performance. PMID:23249919

    Objective. To compare body composition parameters in short children with severe versus moderate and no growth hormone deficiency (GHD). Design and Method. 61 children (40 boys) were studied. Height SDS, BMI Z-score, waist/height ratio (W/HtR), and body composition parameters (BIA) as fat tissue (FAT%), fat-free mass (FFM%), predicted muscle mass (PMM%), and total body water (TBW%) were evaluated. GH secretion in the overnight profile and two stimulation tests and insulin-like growth factor 1 (IGF-1) level were measured. Results. Overall, in 16 (26%) moderate (7.0 > peak GH < 10 ng/mL) and in 11 (18%) severe (GH ≤ 7.0 ng/mL) GHD was diagnosed. In children with sGHD BMI Z-score, W/HtR and FAT% were significantly higher, while FFM%, PMM%, and TBW% were significantly lower versus mGHD and versus noGHD subgroups. No significant differences between mGHD and noGHD were found. There were no differences in height SDS and IGF-1 SDS between evaluated subgroups. Night GH peak level correlated significantly with FAT%, FFM%, PMM%, and TBW%, (p < 0.05) in the entire group. Conclusions. Only sGHD is associated with significant impairment of body composition. Body composition analysis may be a useful tool in distinguishing between its severe and moderate form of GHD. PMID:27656208

    Childhood obesity remains an important public health concern and prevention programmes should be the priority in order to decrease the prevalence of obesity. The aim of this review is to summarize the most effective types of intervention for treating obesity in children and adolescents. A number of identified strategies used to treat childhood obesity range from lifestyle approaches, pharmacotherapy to surgical intervention. Dietary treatment of obese children and adolescents should aim to ensure adequate growth and development by reducing excessive fat mass accumulation, avoiding loss of lean body mass, improving well-being and self-esteem, and preventing cyclical weight regain. Management protocols involve behaviour modifications, family support, and lifestyle changes which are difficult to put into practice and may require multidisciplinary professional teams. The cornerstone of weight loss programmes is to achieve a negative energy balance. There is evidence that dietary interventions are more effective in achieving weight loss when combined with other strategies, such as increasing physical activity levels and/or psychological interventions to promote behavioural changes. Psychological interventions have been employed in an effort to achieve long-term maintenance of behavioural change. Childhood obesity treatments should involve a combination of lifestyle changes including strategies to reduce energy intake, increase physical activity, reduce sedentary activities, facilitate family involvement and change behaviours associated with eating and physical activity. However, drug therapy in obese children must not be used as isolated treatment but as complementary to the traditional treatments of diet, physical activity and lifestyle changes. Besides, surgical procedures have been used to treat severe morbid obesity in children and adolescents when more conservative treatments have proven to be inadequate.

    To evaluate the metabolic effects of long-term treatment with recombinant human (rh) GH in short children with chronic renal failure (CRF), annual oral glucose tolerance tests (oGTT) during rhGH therapy for up to 5 y in 53 prepubertal children with CRF on conservative treatment, dialysis, and after renal transplantation were compared with that of 12 age-matched children treated with rhGH for idiopathic short stature. At the start of rhGH treatment, fasting values of glucose, insulin, glycosylated Hb A (HbA1C), triglycerides, cholesterol, glucose, and insulin responses during oGTT were significantly elevated in all patient groups compared with control subjects (p < 0.001). In the total population, fasting and 2-h postprandial glucose concentrations were inversely correlated with GFR and positively with age and methylprednisolone dosage in transplanted patients. Fasting insulin levels were positively correlated with body mass index and inversely with GFR. RhGH treatment was not associated with a change in fasting or stimulated glucose concentrations in any treatment group throughout the observation period. In contrast, serum insulin levels increased during the first treatment year in all groups, resulting in a more marked elevation of integrated insulin levels in transplant (1402 +/- 179 pM) and dialysis (1025 +/- 114 pM) patients compared with conservatively treated patients (829 +/- 94 pM), and control subjects (719 +/- 89 pM) (p < 0.01). Hyperinsulinemia persisted in all treatment groups for up to 5 y of follow-up. In conclusion, age, renal function, and obesity are the major independent predictors of glucose tolerance in children with CRF. Long-term rhGH treatment does not affect glucose tolerance, but aggravates the preexisting hyperinsulinemia in children with end-stage renal disease. In concert with the dyslipidemia of uremia, the rhGH-promoted hyperinsulinemia may contribute to the long-term risk for premature atherosclerosis in patients with childhood onset

    We investigated the mechanism of topiramate-related appetite loss and exposed its relationship to body weight, body mass index, body fat index, and serum insulin, lipid, leptin, neuropeptide-Y, cortisol, ghrelin, and adiponectin levels. Twenty children with epilepsy were evaluated at baseline and months 3 and 6 of treatment. Their body fat index, leptin, and neuropeptide-Y levels significantly decreased at month 3, whereas significant decreases occurred in body weight, body mass index, body fat index, neuropeptide-Y, cholesterol, and cortisol levels of patients at month 6 compared with baseline. Weight loss during topiramate treatment was attributed to loss of appetite and reduced food intake caused by reductions in neuropeptide-Y. To the best of our knowledge, this study is the first to describe reductions in neuropeptide-Y with topiramate use in humans.

    The prevention of obesity in children with DD is a pressing public health issue, with implications for health status, independent living, and quality of life. Substantial evidence suggests that children with developmental disabilities (DD), including those with intellectual disabilities (ID) and autism spectrum disorder (ASD), have a prevalence of obesity at least as high if not higher than their typically developing peers. The paper reviews what is known about the classic and unique risk factors for childhood obesity in these groups of children, including dietary, physical activity, sedentary behavior, and family factors, as well as medication use. We use evidence from the literature to make the case that primary prevention at the individual/family, school and community levels will require tailoring of strategies and adapting existing intervention approaches.

    The aim of the study was to analyze cardiometabolic risk factors andcarotid intima-media thickness (IMT) in obese children. We studied 122 obese children fulfilling the criteria of the International Obesity Task Force and 58 non-obese children. Anthropometric parameters, blood pressure, lipid profile, C-reactive protein, and adiponectin were assessed in all children. Glucose and insulin during the oral glucose tolerance test were assessed in obese children. The IMT was determined using ultrasound B-mode imaging in 81 obese and 32 non-obese children. We found that obese children had significantly higher levels of lipid andother non-lipid atherogenic indicators, but lower levels of adiponectin compared with non-obese children. The difference in the mean carotid IMT was insignificant in the two groups. Taking the combined groups, the level of adiponectin correlated negatively with body mass index and lipid atherogenic indicators. The IMT strongly correlated with systolic blood pressure in obese children. In the children fulfilling the criteria of metabolic syndrome, 17 out of the 84 obese children older than 10 years of age, IMT was greater than in those who did not fulfil these criteria. We conclude that the coexistence of abdominal obesity with abnormal lipid profile and hypertension leads to the early development of atherosclerosis accompanied by increased carotid intima-media thickness. Obesity initiates the atherosclerotic processes in early childhood.

    Research suggests that the prevalence of obesity in children with autism spectrum disorder (ASD) is at least as high as that seen in typically developing children. Many of the risk factors for children with ASD are likely the same as for typically developing children, especially within the context of today's obesogenic environment. The particular needs and challenges that this population faces, however, may render them more susceptible to the adverse effects of typical risk factors, and they may also be vulnerable to additional risk factors not shared by children in the general population, including psychopharmacological treatment, genetics, disordered sleep, atypical eating patterns, and challenges for engaging in sufficient physical activity. For individuals with ASD, obesity and its sequelae potentially represent a significant threat to independent living, self-care, quality of life, and overall health.

    PubMed Central

    2011-01-01

    Background There have been increases in the obesity and overweight rates in Australian children over the past 25 years and it has been suggested that sugar sweetened beverages (SSB) have played a role in this increase. Objective The objectives of this study were to: (1) examine SSB intakes in the 2007 Australian Children's Nutrition and Physical Activity Survey (2) relate SSB intake to rates of overweight and obesity, socio-economic status (SES), TV viewing time, and activity levels and (3) compare 2007 SSB intakes with data from the 1995 National Nutrition Survey. Design A computer assisted 24 h dietary recall in 4,400 children aged 2-16 years was performed. Results In the 2007 survey 47% of all children reported drinking SSBs with 25% consuming sugar sweetened soft drinks on the day of the survey. The mean consumption of soft drink was 436 g/d/consumer. Activity levels were unrelated to SSB consumption. Television viewing was positively related to soft drink consumption with a difference of 55 g/day from bottom to top tertile of time spent TV viewing (p = 0.015) in children aged 9-16 years. 55% of SSB consumption occurred at home and 10% occurred at school. Lower SES status was associated with a greater prevalence of SSB consumption- 30% for the lowest SES quartile vs 19% in the highest quartile. The proportion of overweight who consumed SSBs (which excludes 100% fruit) was not different from the non-overweight children although the proportion of SSB consumers in the 6% of children who were obese was significant compared with the non-overweight children (59% vs 47%, p < 0.05). In the 2007 survey 23% of children were overweight (17%) or obese (6%) while in the 1995 survey this figure was 21%. The proportion of children consuming SSBs in 1995 and 2007 for selected age groups were: 2-3 years - 25.8% and 12.8% respectively and 4-7 years - 33.6% and 20.5% respectively (p < 0.001 for both).

    2017-01-01

    Approximately 31.8% of U.S. children ages 2 to 19 years are considered overweight or obese. This creates significant challenges to dosing medications that are primarily weight based (mg/kg) and in predicting pharmacokinetics parameters in pediatric patients. Obese individuals generally have a larger volume of distribution for lipophilic medications. Conversely, the Vd of hydrophilic medications may be increased or decreased due to increased lean body mass, blood volume, and decrease percentage of total body water. They may also experience decreased hepatic clearance secondary to fatty infiltrates of the liver. Hence, obesity may affect loading dose, dosage interval, plasma half-life, and time to reach steady-state concentration for various medications. Weight-based dosing is also a cause for potential medication errors. This position statement of the Pediatric Pharmacy Advocacy Group recommends that weight-based dosing should be used in patients ages < 18 years who are < 40 kg; weight-based dosing should be used in patients ≥ 40 kg, unless, unless the recommended adult dose for the specific indication is exceeded; clinicians should use pharmacokinetic analysis for adjusting medications in overweight/obese children; and research efforts continue to evaluate dosing of medications in obese/overweight children.

    2016-01-01

    Childhood obesity is a global epidemic with long term implications. The main cause of obesity is an increase in calorie intake and a decrease in physical activity, but also there is clear evidence suggesting a link between the duration and quality of sleep and obesity risk. Good sleep habits are involved in increased ability to concentrate at school, improvement of general state, immune system development, increased quality of life. On the other hand, there are several mechanisms by which chronic sleep deprivation induces weight gain: disturbance of hormones that control hunger center, increased time for meals, reduced physical activity, metabolic changes. Recently, nighttime sleep duration has declined, in contrast with the increasing prevalence of obesity. Childhood sleep habits have a long term effect on weight, with repercussions even into adulthood. This is the reason why there is increasing interest to include sleep quality on the list for childhood obesity prevention. Sleep represents an important and independent risk factor of obesity in children and adolescents and it should be taken into consideration in the management of obesity.

    2011-07-01

    Obesity has become a worldwide public health problem. Considerable research has shown that the media contribute to the development of child and adolescent obesity, although the exact mechanism remains unclear. Screen time may displace more active pursuits, advertising of junk food and fast food increases children's requests for those particular foods and products, snacking increases while watching TV or movies, and late-night screen time may interfere with getting adequate amounts of sleep, which is a known risk factor for obesity. Sufficient evidence exists to warrant a ban on junk-food or fast-food advertising in children's TV programming. Pediatricians need to ask 2 questions about media use at every well-child or well-adolescent visit: (1) How much screen time is being spent per day? and (2) Is there a TV set or Internet connection in the child's bedroom?

    Objective Hispanic boys are one of the most at-risk groups for the development of obesity, yet few effective interventions have been reported. The objective of this study was to assess Hispanic boys' perceptions of health and obesity to inform future, targeted interventions. Methods This is a qualitative and quantitative study of Hispanic boys aged 8 to 12 years in Forsyth County, North Carolina (n = 25). Three focus groups were conducted combined with anthropometrics and measures of body image. Interview guides were developed to elicit children's perceptions of obesity, nutrition, physical activity, and family influences over health behaviors. Focus group comments were recorded and transcribed. Transcripts were coded using a multistage inductive approach, and grounded theory was used to analyze responses. Results The following 6 themes emerged: boys had a limited and superficial understanding of health, nutrition, and activity; perceptions of health were based on muscular appearance, frequency of exercise, and media messages; boys had negative perceptions of overweight children and physical performance; family meals were infrequent and unstructured; boys prefer restaurants with fast food, buffets, and entertainment; and neighborhood safety influences activity participation. Boys did not mention parents as influencers of health and habits. Conclusions From their findings, the authors have outlined several key areas that will inform clinicians and researchers in the prevention and treatment of obesity in this highly vulnerable population.

    2011-10-01

    Associations between appetite and adiposity have not been examined in clinical samples of obese children. The Children's Eating Behaviour Questionnaire (CEBQ) was used to compare appetite in community (n=406) and clinical (n=66) samples. Clear graded patterns were seen for food responsiveness and emotional overeating; levels increased with increasing BMI SDS and the clinical sample scored highest. The reverse was seen for satiety responsiveness/slowness in eating. Differences were not solely explained by weight differences, suggesting that the clinical sample had more pronounced 'obesogenic' appetitive traits. This could make adherence to dietary guidance difficult.

    Based on their clinical impression, the authors hypothesized that children with obesity may more commonly present with perforated appendicitis. Therefore, the authors reviewed their experience from 2008 to 2010 to determine whether obesity affected the clinical presentation of appendicitis. Variables studied were height, weight, use of diagnostic imaging, and clinical findings of appendicitis at presentation. Outcomes assessed were length of stay and complication rate. The study identified 319 patients with appendicitis. Children with obesity were more likely (P = .026) to present with perforation (28/62, 45%) than nonobese patients (78/257, 30%). Neither length of stay nor complication rate was affected by the presence of obesity. The data suggest that children with obesity are more likely to present with perforated appendicitis. This finding suggests that the diagnosis of appendicitis may be more difficult in obese patients or their presentation may be delayed. Practitioners should have heightened awareness in children with obesity and symptoms of abdominal pain.

    Childhood obesity is a major concern in today's society. Research suggests the inclusion of the views and understandings of a target group facilitates strategies that have better efficacy. The objective of this study was to explore the concepts and themes that make up children's understandings of the causes and consequences of obesity. Participants were selected from Reception (4–5 years old) and Year 6 (10–11 years old), and attended a school in an area of Sunderland, in North East England. Participants were separated according to age and gender, resulting in four focus groups, run across two sessions. A thematic analysis (Braun & Clarke, 2006) identified overarching themes evident across all groups, suggesting the key concepts that contribute to children's understandings of obesity are “Knowledge through Education,” “Role Models,” “Fat is Bad,” and “Mixed Messages.” The implications of these findings and considerations of the methodology are discussed in full.

    Childhood obesity has been identified as one of the most important risk factors of developing cardiovascular diseases. The global prevalence of overweight and obesity among children shows an increasing tendency. Many of overweight or obese children will become obese adults with enhanced risk for cardiovascular diseases. Childhood obesity is often accompanied by serious consequences such as dyslipidemia, hypertension, diabetes, pro-inflammatory state and non-alcoholic fatty liver disease. Hypertension, high LDL-cholesterol and triglyceride concentrations, insulin resistance, inflammation and disturbances in adipocytokines secretion are associated with endothelial dysfunction which precedes the development of atherosclerosis. Obese children and adolescents with a clinically-proven non-alcoholic fatty liver disease, which is currently recognized as the hepatic component of metabolic syndrome, are at more severe cardiovascular risk compared with normal-weight. Obesity-related insulin resistance is highly prevalent in children and adolescents, and is associated with the increased lifetime risk of type 2 diabetes and cardiovascular disease. Adipokines contribute to obesity-atherosclerosis relationships yet among several recently discovered adipokines only few (adiponectin, resistin, chemerin, fibroblast growth factor 21, apelin) have been partly studied in obese pediatric population. The aim of this review was to describe the spectrum of cardiovascular abnormalities observed in children with overweight and obesity and the role of laboratory in the assessment of cardiometabolic risk in order to differentiate between healthy obese and those at risk to most effectively prevent progression of cardiovascular disease in childhood.

    The objective of this study was to estimate the prevalence of obesity among schoolchildren in Khartoum state, Sudan. Multistage stratified random sampling methodology was used. Sampling included different residential areas within the state. A total of 1138 children between the ages of 10 and 18 years were involved in the study. More than 9% of the children were obese, 10.8% were overweight whereas combined overweight/obesity scored 20.5%. The prevalence of combined overweight/obesity among higher, middle and lower socioeconomic class children was 56.8, 27.3 and 3.1%, respectively. These figures, being higher than those reported among Nigerian and South African children, living in similar conditions, may refer to an emerging problem of overweight and obesity especially among children of the higher and middle class families. Adoption of national programs of promoting healthy food habits and physical activity among children is recommended.

    The obesity epidemic has become a common concern among pediatricians, with an estimated 32 % of US children and adolescents classified as overweight and 18 % as obese. Along with the increase in obesity, a growing body of evidence demonstrates that chronic diseases, such as Type 2 diabetes, primary hypertension, and hyperlipidemia, once thought to be confined solely to adulthood, are commonly seen among the obese in childhood. Following a brief summary of the diagnosis and evaluation of hypertension in obese children and adolescents, this review will highlight recent research on the treatment of obesity-related hypertension. Pharmacologic and non-pharmacologic treatment will be discussed. Additionally, current and emerging therapies for the primary treatment of obesity in children and adolescents, which have been gaining in popularity, will be reviewed.

    The present study investigates the behavioral performance and event-related potentials (ERPs) in children with obesity and healthy weight children when performing a visuospatial attention task. Twenty-six children with obesity (obese group) and 26 healthy weight children (control group) were recruited. Their behavioral performance during a variant of the Posner paradigm was measured, and brain ERPs were recorded concurrently. The behavioral data revealed that the obese group responded more slowly, especially in the invalid condition, and exhibited a deficit in attentional inhibition capacity as compared to the control group. In terms of cognitive electrophysiological performance, although the obese group did not show significant differences on P3 latency elicited by the target stimuli when compared to the control group, they exhibited smaller P3 amplitudes when performing the visuospatial attention task. These results broaden previous findings, and indicate that childhood obesity is associated with a reduced ability to modulate the executive function network which supports visuospatial attention.

    Children with developmental or physical disabilities, many of whom face serious health-related conditions, also are affected by the current obesity crisis. Although evidence indicates that children with disabilities have a higher prevalence of obesity than do children without disabilities, little is known of the actual magnitude of the problem in this population. To address this concern, the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) held a conference on obesity in children with intellectual, developmental, or physical disabilities, bringing together scientists and practitioners in the fields of obesity and disability to foster collaboration, identify barriers to healthy weight status in populations with disabilities, propose avenues to solutions through research and practice, and develop a research agenda to address the problem. This article describes current knowledge about prevalence of obesity in this population, discusses factors influencing obesity risk, and summarizes recommendations for research presented at the conference.

    Hypertension is increasingly common in overweight and obese children. The mechanisms behind the development of hypertension in obesity are complex, and evidence is limited. In order to effectively treat obese children for hypertension, it is important to have a deeper understanding of the pathophysiology of hypertension in obese children. The present review summarizes the main factors associated with hypertension in obese children and discusses their potential role in its pathophysiology. Systematic searches were conducted in PubMed and EMBASE for articles published up to October 2014. In total, 60 relevant studies were included. The methodological quality of the included studies ranged from weak to strong. Several factors important in the development of hypertension in obese children have been suggested, including endocrine determinants, such as corticosteroids and adipokines, sympathetic nervous system activity, disturbed sodium homeostasis, as well as oxidative stress, inflammation and endothelial dysfunction. Understanding the pathophysiology of hypertension in overweight and obese children is important and could have implications for its screening and treatment. Based on solely cross-sectional observational studies, it is impossible to infer causality. Longitudinal studies of high methodological quality are needed to gain more insight into the complex mechanisms behind the development of hypertension in obese children.

    Prejudice against obese people has been widely confirmed in scientific papers. Therefore, recent studies have increasingly focused on investigating the individual and cultural factors related to attitudes towards obesity. Since there have been no comparative studies involving Gypsy people, our present research aimed at exploring the possible discrepancies in children's attitudes towards obese children between Gypsy and Hungarian cultures. Our survey included 247 children aged 9-16 (108 boys and 139 girls), of which 136 considered themselves Hungarian (55.1 %), while 111 children (44.9 %) claimed themselves as Gypsy. The subjects were asked to rank six male and six female figure drawings according to their preference. Each sequence of figure drawings included a healthy child, an obese child, and four drawings depicted children with disabilities. According to our results, the drawings portraying the healthy child figure were rated most preferable and those portraying the obese child figure the least preferable amongst the subjects regardless of gender and origin. However, the obese girl figures and boy figures were rated significantly more positively by Gypsy children than Hungarian children. Our results suggest that there is a difference in attitude towards obesity among Gypsy and Hungarian children. Therefore, it is worthwhile to further explore this phenomenon.

  15. Proteomic analysis allows for early detection of potential markers of metabolic impairment in very young obese children

    2014-01-01

    Background Early diagnosis of initial metabolic derangements in young obese children could influence their management; however, this impairment is frequently not overt, but subtle and undetectable by routinely used clinical assays. Our aim was to evaluate the ability of serum proteomic analysis to detect these incipient metabolic alterations in comparison to standard clinical methods and to identify new candidate biomarkers. Methods A cross-sectional study of fasting serum samples from twenty-two prepubertal, Caucasian obese (OB; 9.22 ± 1.93 years; 3.43 ± 1.08 BMI-SDS) and twenty-one lean controls (C; 8.50 ± 1.98 years; -0.48 ± 0.81 BMI-SDS) and a prospective study of fasting serum samples from twenty prepubertal, Caucasian obese children (11 insulin resistant [IR]) before (4.77 ± 1.30 BMI-SDS) and after weight reduction (2.57 ± 1.29 BMI-SDS) by conservative treatment in a reference hospital (Pros-OB) was performed. Proteomic analysis (two-dimension-eletrophoresis + mass spectrometry analysis) of serum and comparative evaluation of the sensitivity of routinely used assays in the clinics to detect the observed differences in protein expression level, as well as their relationship with anthropometric features, insulin resistance indexes, lipid profile and adipokine levels were carried out. Results Study of the intensity data from proteomic analysis showed a decrease of several isoforms of apolipoprotein-A1, apo-J/clusterin, vitamin D binding protein, transthyretin in OBvs. C, with some changes in these proteins being enhanced by IR and partially reversed after weight loss. Expression of low molecular weight isoforms of haptoglobin was increased in OB, enhanced in IR and again decreased after weight loss, being positively correlated with serum interleukin-6 and NAMPT/visfatin levels. After statistical correction for multiple comparisons, significance remained for a single isoform of low MW haptoglobin (OB vs. C and IR vs. non-IR) and

    Objective: Limited information is available about the use of neck circumference (NC) to assess obesity in preschool children. This study aims to provide NC percentiles and determine the cut-off levels of NC as a measure to assess obesity in preschool children. Methods: The data were obtained from the Anthropometry of Turkish Children aged 0-6 years (ATCA-06) study database. A total of 21 family health centers were chosen and children aged 2-6 years old from all socioeconomic levels were randomly selected from the lists of district midwives; 1766 children (874 male and 892 female; 88.3% of sample size) were included in the study. The smoothed centile curves of NC were constructed by the LMS method. Receiver operating characteristic (ROC) analysis was performed to calculate cut-off points for NC using body mass index ≥95th percentile. Results: Mean NC was greater in males than females. Cut-off values for obesity were found to be statistically significant in both genders other than 3 years old boys. The NC percentiles of Turkish preschool children were slightly greater than those of other European preschool children in both genders. This difference disappeared around the adiposity rebound period. The 97th percentile values for Turkish preschool children continue to be greater in both genders. Conclusion: NC may be useful to define obesity in preschool children. Since ethnic and various other factors may have a role in incidence of obesity, local reference data are important in assessment of obesity. PMID:27660068

    There are widespread differences in overweight/obesity prevalence in children, and understanding the reasons for this is very important. The present study aims: (I) to conduct a meta-analysis on overweight/obesity prevalence in Portuguese children; (II) to identify differences in biological and behavioural characteristics between normal-weight and overweight/obese children; and (III) to investigate the importance of individual- and school-level correlates of variation in children's BMI using multilevel modelling. A search was done for all published papers including Portuguese children during the last decade; further, 686 Portuguese children (9-11 years old) were sampled and their BMI, family income, maturity offset, nutritional habits, physical activity, sedentariness, sleep time, and school environment information were collected. Results showed a stabilization of overweight/obesity during the last decade, 30.6% (95%CI: 0.287-0.34) for boys, 28.4% (95%CI: 0.23-0.35) for girls, and 30.3% (95%CI: 0.27-0.34) for boys and girls together. Differences between weight groups were only found in individual-level biological traits. The multilevel analysis did not identify significant contributions of school-level variables to children's BMI variation. In conclusion, no increase was found in the prevalence of overweight/obesity among Portuguese children since 2000. Normal-weight and overweight/obese children only differ in individual-level characteristics, and school context variables were not related to variation in BMI.

    The perception of obesity among people has not changed significantly regardless numerous public educational programs. Reasons for obesity pandemics are numerous and complex, but can be mostly resumed to life-style changes. The aim of this research was to determine connection between socioeconomic factors and obesity with children of our region. Study included pupils aged 7-8 from 19 first grades in 8 primary schools in Osijek-Baranya County. Body height and weight were measured and socioeconomic data status were collected. Socioeconomic status included data on marital status, educational level, employment, number of children in the family, kindergarten attendance and urban/rural location and also smoking habits of parents. BMI was calculated as a parameter for obesity assessment according to Croatian reference values. Total of 372 children were measured. There were 6.5% of overweight children (BMI between 90th and 97th percentile) and 2.4% of obese children (BMI above 97th percentile). The prevalence of obese children in our research was 8.9%. Obesity is not influenced by rural/urban residence, marital status of parents, number of children in the family, mother's education, or by parents' smoking habits. Positive correlation between obesity and father's education and parents' unemployment was found. Available literature data, same as our study, did not show consistent association between socioeconomic factors and obesity with children. Contradictory results of different studies can be a result of a small sample, difference in study design and different criteria for defining categories within investigated socioeconomic factor.

    Objectives The purpose of this study was to identify the perception of childhood obesity in mothers of preschool children using Q methodology. Methods A total of 38 Q statements about childhood obesity were obtained from 41 participants. The QUANL PC program was used to analyze the results. Results There were three types of perception toward obesity in mothers of preschool children: the “authoritative discipline type,” the “generous home meal focused type,” and the “home meal based on household financial situation type.” Conclusion The perception of mothers toward childhood obesity can affect the extent of maternal interaction with children or meal preparation for the family. Based on these results, it is necessary to plan specific programs according to the types of maternal perception toward childhood obesity. PMID:25938022

    Objective: Thyroid abnormalities are common in obese children. The aim of the present study was to examine the prevalence of subclinical hypothyroidism (SH) and to determine how circulating thyroid hormone concentrations correlate with anthropometrics in Danish lean and obese children and adolescents. Methods: In this cross-sectional study, we included 3006 children and adolescents, aged 6-18 years, from the Registry of the Danish Childhood Obesity Biobank. The overweight/obese group (n=1796) consisted of study participants with a body mass index (BMI) standard deviation score (SDS) ≥1.28. The control group (n=1210) comprised lean children with a BMI SDS <1.28. All participants were characterized by anthropometrics (weight, height, and waist circumference) and fasting serum concentrations of thyroid-stimulating hormone (TSH), free triiodothyronine, and free thyroxine (fT4) at baseline. Results: The prevalence of SH was higher among overweight/obese compared to lean study participants (10.4% vs. 6.4%, p=0.0001). In the overweight/obese group, fasting serum TSH concentrations were associated positively with BMI SDS (p<0.0001) and waist-height ratio (WHtR) (p<0.0001) independent of age, sex, and pubertal developmental stage, whereas fasting serum fT4 concentrations were associated positively only with WHtR. The odds ratio of exhibiting SH was 1.8 when being overweight/obese compared with lean (p=0.0007) and 1.8 when presenting with a WHtR >0.5 (p=0.0003). Conclusion: The prevalence of SH was higher among overweight/obese study participants. The positive correlations of circulating TSH and fT4 with WHtR suggest that central obesity, independent of the overall degree of obesity, augments the risk of concurrent thyroid abnormalities in children and adolescents with obesity.

    2011-01-01

    Background Inadequate eating behavior and physical inactivity contribute to the current epidemic of childhood obesity. The aim of this study was to assess the association between eating behavior scores and childhood obesity in Chilean children. Design and methods We recruited 126 obese, 44 overweight and 124 normal-weight Chilean children (6-12 years-old; both genders) according to the International Obesity Task Force (IOTF) criteria. Eating behavior scores were calculated using the Child Eating Behavior Questionnaire (CEBQ). Factorial analysis in the culturally-adapted questionnaire for Chilean population was used to confirm the original eight-factor structure of CEBQ. The Cronbach's alpha statistic (>0.7 in most subscales) was used to assess internal consistency. Non-parametric methods were used to assess case-control associations. Results Eating behavior scores were strongly associated with childhood obesity in Chilean children. Childhood obesity was directly associated with high scores in the subscales "enjoyment of food" (P < 0.0001), "emotional overeating" (P < 0.001) and "food responsiveness" (P < 0.0001). Food-avoidant subscales "satiety responsiveness" and "slowness in eating" were inversely associated with childhood obesity (P < 0.001). There was a graded relation between the magnitude of these eating behavior scores across groups of normal-weight, overweight and obesity groups. Conclusion Our study shows a strong and graded association between specific eating behavior scores and childhood obesity in Chile. PMID:21985269

    2006-11-01

    Facing the undesirable health consequences of being obese, an important question is why some people are not able to resist eating to excess. It is theorized that increased impulsivity at least partly underlies the inability to control eating behaviour; being more impulsive is supposed to make it more difficult to resist food intake. Thirty-three obese children in a residential setting and 31 lean control children are tested. Impulsivity is measured with two behavioural measures (inhibitory control and sensitivity to reward) and questionnaires. Results show that the obese children in treatment were more sensitive to reward and showed less inhibitory control than normal weight children. In addition, the obese children with eating binges were more impulsive than the obese children without eating binges. Most interesting finding was that the children that were the least effective in inhibiting responses, lost less weight in the residential treatment program. To conclude: impulsivity is a personality characteristic that potentially has crucial consequences for the development and maintenance, as well as treatment of obesity.

    The aim of this study was to investigate the correlation between each parent's Body Mass Index (BMI) and maternal age with weight status of children. This was an analytic cross-sectional study which was conducted on 12-year-old students from different areas in Rasht, north part of Iran. The checklist included demographic characteristics such as age, maternal age during childbirth, student and maternal height and weight, child rank. Data were analyzed by Pearson correlation analysis, paired t-test and ANOVA test and chi-square in SPSS software 19.0. A P-value less than 0.05 were considered statistically significant. A total of 200 adolescents participated in this study consisted of 106 (53%) boys. Results showed a significant correlation between students' BMI and parental BMI and father's weight. Also, there was a significant correlation between students' weight with parental BMI and father's weight, and birth rankIn conclusion, the role of the family in changing nutritional habits of children must be considered because through parental education and changing their perceptions we can prevent obesity.

    The present study examined objectively measured physical activity in Malaysian children and compared the differences in physical levels between obese and healthy weight children. Eighty-six obese children were matched for age and sex with 86 healthy weight children with median age 9.5 years. Habitual physical activity and sedentary behaviour were measured over 5 days using Actigraph accelerometers. Time spent sedentary was significantly higher in the obese group (90% vs. 86% of daytime; p = 0.001). Moderate-to-vigorous-intensity physical activity was significantly higher in the healthy weight group (1.2 vs. 0.7% of daytime, p < 0.001). In both healthy weight and obese children, physical activity levels were exceptionally low, although moderate-to-vigorous-intensity physical activity was significantly lower in the obese group than the healthy weight group. Efforts to prevent and treat obesity in Malaysian children will need a substantial focus on the promotion of reductions in sedentary behaviour and increases in physical activity.

    Reports on sudden cardiac death (SCD) of children and adolescents treated with stimulant agents have raised concerns regarding the need for cardiovascular monitoring and risk stratification schedules. Cardiac ventricular late potentials (LPs) represent delayed ventricular activation that might predispose to fatal ventricular arrhythmias and SCD in cardiac patients. LPs have not previously been measured in children with attention deficit/hyperactivity disorder (ADHD). LPs were measured in 18 physically healthy ADHD children (5 girls and 13 boys, age 11.9 ± 2.5 years, treatment duration 2.6 ± 1.9 years) before and 2 h after oral methylphenidate administration. No significant changes were detected and LPs were found to be within normal ranges. In conclusion, this preliminary small-scale study suggests that methylphenidate in physically healthy children with ADHD was not associated with cardiac ventricular LPs, suggesting the safety of the agent in this age group.

    Obesity is becoming an increasingly prevalent problem among American children. Screening for obesity associated comorbid conditions has been shown to be inconsistent. The current study was undertaken to explore patterns of ordering screening tests among obese pediatric patients. We analyzed electronic medical records (EMR) from 69,901 patients ages 2-18 years between June 1999 and December 2008. Obese children who had documented diagnoses of obesity were identified based on International Classification of Diseases, Ninth Revision codes. Screening rates for glucose, liver, and lipid abnormalities were assessed. Regression analysis was used to examine impact of patient characteristics and temporal trends were analyzed. Of the 9,251 obese diagnosed patients identified, 22% were screened for all three included obesity-related conditions: diabetes, liver, and lipid abnormalities; 52% were screened for glucose abnormalities; 30% for liver abnormalities; and 41% for lipid abnormalities. Increasing BMI and age were associated with increased rates of screening. Females and Hispanic patients were more likely to be screened. The majority of screening was ordered under "basic metabolic panel," "hepatic function panel," and "full lipid profile" for each respective condition. The percentages of patients screened generally increased over time, although the percentages screened for diabetes and lipid abnormalities seemed to plateau or decrease after 2004. Even after diagnosis, many obese patients are not receiving recommended laboratory screening tests. Screening increased during the study period, but remains less than ideal. Providers could improve care by more complete laboratory screening in patients diagnosed with obesity.

    Oxidative stress and nitric oxide (NO) appear to represent important links between obesity and cardiovascular, metabolic and/or renal disease. We investigated whether oxidative stress and NO production/metabolism are increased in overweight and obese prepubertal children and correlate with cardiometabolic risk and renal function. We performed a cross-sectional evaluation of 313 children aged 8-9 years. Anthropometrics, 24-h ambulatory blood pressure, pulse wave velocity (PWV), insulin resistance (homoeostasis model assessment index (HOMA-IR)), inflammatory/metabolic biomarkers, estimated glomerular filtration rate (eGFR), plasma total antioxidant status (TAS), plasma and urinary isoprostanes (P-Isop, U-Isop), urinary hydrogen peroxide (U-H2O2), and plasma and urinary nitrates and nitrites (P-NOx, U-NOx) were compared among normal weight, overweight and obese groups, according to WHO BMI z-score reference. U-Isop were increased in the obese group, whereas U-NOx were increased in both overweight and obese children. U-Isop were positively correlated with U-H2O2, myeloperoxidase (MPO), high-sensitivity C-reactive protein, HOMA-IR and TAG. TAS correlated negatively with U-Isop and MPO and positively with PWV. HOMA-IR and U-H2O2 were associated with higher U-Isop, independently of BMI and eGFR, and total cholesterol and U-H2O2 were associated with U-NOx, independently of BMI, eGFR values and P-NOx concentration. In overweight and obese children, eGFR decreased across P-NOx tertiles (median: 139·3 (25th, 75th percentile 128·0, 146·5), 128·0 (25th, 75th percentile 121·5, 140·4), 129·5 (25th, 75th percentile 119·4, 138·3), P for linear trend=0·003). We conclude that oxidant status and NO are increased in relation to fat accumulation and, even in young children, they translate into higher values of cardiometabolic risk markers and affect renal function.

    Background Regular body mass index (BMI) screenings in schools is important to ensure that 3- to 6-year-old children are not negatively affected by obesity in terms of their current and future health. Objectives The aim of this study was to determine the overweight and obesity results of 3- to 6-year-old children and to guide children and their family in making healthier dietary choices by informing them. Methods This analytical-descriptive study was conducted in Corum, Turkey, in the year 2011. The study’s sample consisted of all available 3- to 6-year-old children entering nursery school (specifically, the Buharaevler, Karsıyaka, Nasrettin Hoca, Ulukavak, Mimar Sinan, and Sevgi nursery schools). Findings from the study were statistically analyzed using the SPSS 15.0 program. The Chi-square test and analysis of variance (ANOVA) program were used in the comparison of study data. A p-value of less than 0.05 was considered significant. Results It was determined that 9.5% of the participating female children and 5.2% of the male children were underweight and that the boys were more obese than the girls in general. The correlation between the child’s gender and their BMI was not found to be statistically significant (P-value > 0.05). The overweight frequency of the children was 12.1%, and the obesity frequency was 14.3%. Furthermore, it was determined that the obesity rates of the children increased with their age. Accordingly, the correlation between the child’s age and BMI was found to be statistically significant (P-value < 0.05). Conclusions An approach to preventing obesity must not be enacted only in health centers. Schools should also offer information and resources for families in order to prevent obesity in children.

    AIM: The purpose of this study was to report obesity status and identify any dietary substances that may be related to obesity in healthy school children from Northern Greece. METHODS: Four hundred and twenty-five (n = 425) children were randomly selected to participate in the study. A 24-h recall of three days (two weekdays and one weekend day) was used to analyze the dietary data of the subjects. RESULTS: Out of 425 subjects, 146 (34.3%) of them were found to be overweight and obese. Energy, protein, carbohydrate and thiamin intake was statistically positively correlated with obesity while dietary iron intake was statistically negatively correlated with obesity. Multivariate logistic regression analysis showed that the children with dietary iron deficiency were 1.128 (95% CI: 0.002, 0.161 P < 0.031) times more likely of being obese compared to the normal group after adjustment for energy intake. CONCLUSIONS: Although most of the dietary intakes of our subjects were adequate, special consideration should be given to energy, carbohydrate, protein, and sugar and iron intake especially and its relation to obesity. Furthermore, additional studies are required to investigate any possible relation of low dietary iron consumption and obesity. PMID:27335587

  17. Obesity and asthma in children: current and future therapeutic options.

    PubMed

    2014-06-01

    With the childhood prevalence of obesity and asthma increasing, it is important for pediatric professionals to appreciate that obesity modifies the diagnosis and management of asthma. These disease modifications present challenges to clinical management, including decreased responsiveness to controller therapy and decreased quality of life compared with normal-weight asthmatic children. While consensus guidelines do not currently suggest specific changes in asthma management for obese patients, management of some patients may be improved with consideration of the latest evidence. This article briefly summarizes what is known regarding the complex relationship between obesity and asthma in children, and discusses practical issues associated with the diagnosis and effective clinical management of asthma in obese children. On average, obese patients with asthma do not respond as well to inhaled corticosteroid therapy. Management approaches including weight loss and routine exercise are safe, and may improve important asthma outcomes. Asthma providers should learn to facilitate weight loss for their obese patients. In addition, pharmacologic interventions for weight loss in obese asthma, though not currently recommended, may soon be considered.

    This article examines obesity among minority parents and children in the context of culture, socioeconomic status, and the parent-child dyad. Knowing parental attitudes about eating habits, food preparation, and dietary guidelines is crucial to addressing childhood obesity. Parents of African American, Caribbean, and Hispanic descent participated in focus groups to explore their attitudes and practices regarding the food choices they make for themselves and their 6- to 12-year-old children. Cultural identification and time constraints were identified as key themes that influence food choice decisions. Several recommendations are made for health care practitioners working with families to reduce the incidence of obesity.

    Objective To determine the association between the metabolic syndrome in children (MS) and the pre-pregnancy nutritional status of the mother. Design and methods A total number of 180 children aged between 6–19 years were examined. Self reported data about parents and their children were collected. The children underwent physical examination; weight, height, waist circumference, blood pressure (BP) were measured. The nutritional status of the children was assessed by body mass index (BMI) and laboratory tests needed to diagnose MS were performed. IDF criteria for MS were used in children 10 years and older, and age and gender specific cut-off points in children younger than 10 years. The mothers were classified in the normal weight, overweight and obese categories according to the pre-pregnancy BMI. The statistical analysis of the data was descriptive and inferential analysis. In the bivariate analysis of the association between qualitative variables, we used the Chi-Square test and the exact Fisher test. The statistical analysis was performed with SPSS v 13.0. Results 73 (40.55%) children were normal weight, 54 (30%) were overweight and 53 (29.44%) were obese. None of the normal weight children, 16 (29.60%) of the overweight and 23 (43.40%) of the obese ones had MS; 125 (69.44%) of the mothers were normal weight, 44 (24.44%) were overweight and 11 (6.11%) were obese. Pre-pregnancy maternal BMI was significantly associated with offspring MS in both genders, obese children and in the 10–16 age group. Conclusions Pre-pregnancy maternal overweight/obesity represents a risk factor for offspring MS. The results are very difficult to compare between studies because of different cut-off values and definition of MS in children. If prevention is the goal rather than treatment, the perinatal period may be an important focus for future research. PMID:26527958

    The most common etiology of non-syndromic monogenic obesity are mutations in gene for the Melanocortin-4 receptor (MC485) with variable prevalence in different countries (1.2-6.3 % of obese children). The aim of our study was 1) to search for MC4R mutations in obese children in Slovakia and compare their prevalence with other European countries, and 2) to describe the phenotype of the mutation carriers. DNA analysis by direct Sanger sequencing of the coding exons and intron/exon boundaries of the MC4R gene was performed in 268 unrelated Slovak children and adolescents with body mass index above the 97(th) percentile for age and sex and obesity onset up to 11 years (mean 4.3+/-2.8 years). Two different previously described heterozygous loss of function MC4R variants (i.e. p.Ser19Alafs*34, p.Ser127Leu) were identified in two obese probands, and one obese (p.Ser19Alafs*34), and one lean (p.Ser127Leu) adult family relatives. No loss of function variants were found in lean controls. The prevalence of loss-of-function MC4R variants in obese Slovak children was 0.7 %, what is one of the lowest frequencies in Europe.

    The aim of this study was to investigate the expression and clinical significance of the obesity-associated gene STEAP4 in obese children. Fifty-three obese children and 33 children with a standard body weight (control) from our hospital were recruited to this study. The expression of STEAP4 mRNA and protein in the adipose tissue were detected by reverse transcriptase polymerase chain reaction and enzyme-linked immunosorbent assay, respectively, in order to analyze the relationship between STEAP4 mRNA and protein levels and blood pressure, blood lipid profile, blood glucose levels, and inflammation in obese children. Obese children showed significantly lower levels of STEAP4 mRNA and protein in the adipose tissue compared to the control subjects (P < 0.05). The obese subjects exhibited significantly higher diastolic blood pressure (DBP), systolic blood pressure (SBP), total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), fasting plasma glucose (FPG), interleukin (IL)-6, and tumor necrosis factor (TNF)-α levels, and a significantly lower high-density lipoprotein (HDL) level, compared to the control subjects (P < 0.05). Correlation analysis revealed that STEAP4 expression was negatively correlated with the DBP, SBP, TC, TG, LDL, FPG, IL-6, and TNF-α levels, and was positively correlated with the HDL level (P < 0.05). In conclusion, the expression of STEAP4 was significantly downregulated in the adipose tissue of obese children and was closely related to the blood pressure, blood lipid, blood glucose, and inflammation in these patients; therefore, these results could provide a theoretical basis for the treatment of childhood obesity.

    Context Patients with pseudohypoparathyroidism type 1a (PHP-1a) develop early-onset obesity. The abnormality in energy expenditure and/or energy intake responsible for this weight gain is unknown. Objective The aim of this study was to evaluate energy expenditure in children with PHP-1a compared with obese controls. Patients We studied 6 obese females with PHP-1a and 17 obese female controls. Patients were recruited from a single academic center. Measurements Resting energy expenditure and thermogenic effect of a high fat meal were measured using whole room indirect calorimetry. Body composition was assessed using whole body dual energy x-ray absorptiometry. Fasting glucose, insulin and hemoglobin A1C were measured. Results Children with PHP-1a had decreased resting energy expenditure compared with obese controls (P <0.01). After adjustment for fat free mass, the PHP-1a group’s resting energy expenditure was 346.4 kcals/day less than obese controls (95% CI [−585.5 to −106.9], P <0.01). The thermogenic effect of food, expressed as percent increase in postprandial energy expenditure over resting energy expenditure, was lower in PHP-1a patients than obese controls but did not reach statistical significance (absolute reduction of 5.9%, 95% CI [−12.2% to 0.3%], P = 0.06). Conclusions Our data indicate that children with PHP-1a have decreased resting energy expenditure compared with obese controls and that may contribute to the development of obesity in these children. These patients may also have abnormal diet-induced thermogenesis in response to a high fat meal. Understanding the causes of obesity in PHP-1a may allow for targeted nutritional or pharmacologic treatments in the future. PMID:23229731

  3. Similarities between obesity in pets and children: the addiction model.

    PubMed

    Pretlow, Robert A; Corbee, Ronald J

    2016-09-01

    Obesity in pets is a frustrating, major health problem. Obesity in human children is similar. Prevailing theories accounting for the rising obesity rates - for example, poor nutrition and sedentary activity - are being challenged. Obesity interventions in both pets and children have produced modest short-term but poor long-term results. New strategies are needed. A novel theory posits that obesity in pets and children is due to 'treats' and excessive meal amounts given by the 'pet-parent' and child-parent to obtain affection from the pet/child, which enables 'eating addiction' in the pet/child and results in parental 'co-dependence'. Pet-parents and child-parents may even become hostage to the treats/food to avoid the ire of the pet/child. Eating addiction in the pet/child also may be brought about by emotional factors such as stress, independent of parental co-dependence. An applicable treatment for child obesity has been trialled using classic addiction withdrawal/abstinence techniques, as well as behavioural addiction methods, with significant results. Both the child and the parent progress through withdrawal from specific 'problem foods', next from snacking (non-specific foods) and finally from excessive portions at meals (gradual reductions). This approach should adapt well for pets and pet-parents. Pet obesity is more 'pure' than child obesity, in that contributing factors and treatment points are essentially under the control of the pet-parent. Pet obesity might thus serve as an ideal test bed for the treatment and prevention of child obesity, with focus primarily on parental behaviours. Sharing information between the fields of pet and child obesity would be mutually beneficial.

    Objective: To evaluate the relationship between periaortic fat thickness (PAFT) and parameters involved in the development of metabolic complications of the cardiovascular system in obese children and to assess the usefulness of echocardiographic measurements of PAFT in correlation with cardiovascular risk factors. Methods: The study was conducted with 263 obese and 100 healthy children and adolescents. PAFT was measured with echocardiography method which was recently performed in obese children and adolescents. Results: PAFT was significantly higher in the obese group (0.258±0.031 mm) than in the control group (0.137±0.032 mm) (p<0.001). In multivariable regression analysis, body mass index-standard deviation score and total body fat were predictors of PAFT. The area under the receiver operating characteristic curve was 0.989 and was quite significant at p<0.001. PAFT above 0.179 mm was determined as the cut-off value in obese children and adolescents (sensitivity=1, specificity=0.97). Conclusion: The measurement of PAFT in obese children and adolescents may be a good method to reveal the presence of early cardiovascular risk. PMID:26758313

    Mothers' work hours are likely to affect their time allocation towards activities related to children's diet, activity and well-being. For example, mothers who work more may be more reliant on processed foods, foods prepared away from home and school meal programs for their children's meals. A greater number of work hours may also lead to more unsupervised time for children that may, in turn, allow for an increase in unhealthy behaviors among their children such as snacking and sedentary activities such as TV watching. Using data on a national cohort of children, we examine the relationship between mothers' average weekly work hours during their children's school years on children's dietary and activity behaviors, BMI and obesity in 5th and 8th grade. Our results are consistent with findings from the literature that maternal work hours are positively associated with children's BMI and obesity especially among children with higher socioeconomic status. Unlike previous papers, our detailed data on children's behaviors allow us to speak directly to affected behaviors that may contribute to the increased BMI. We show that children whose mothers work more consume more unhealthy foods (e.g. soda, fast food) and less healthy foods (e.g. fruits, vegetables, milk) and watch more television. Although they report being slightly more physically active, likely due to organized physical activities, the BMI and obesity results suggest that the deterioration in diet and increase in sedentary behaviors dominate.

    2006-01-01

    Information on reproducibility of dual-energy X-ray absorptiometry (DXA) measurements is essential because DXA is frequently used by clinicians and researchers to assess body composition changes. We estimated measurement error and absolute and relative smallest detectable differences (SDDs) for fat, lean, and bone mass in children. The SDD is the change necessary to be confident that the change is not a consequence of measurement error. Duplicate whole body DXA (Hologic QDR 4500A, Hologic Inc., Waltham, MA) scans were obtained on 32 obese and 34 non-obese children ages 6-19 yr. Absolute (kg) and relative (coefficient of variation) measurement error and SDD were calculated. Absolute SDDs for fat and lean were higher for obese (1.39 and 1.30 kg, respectively) than for non-obese children (0.42 and 0.47 kg, respectively). The %SDD for fat was lower for obese (3.58%) than non-obese children (5.24%), but for lean the %SDD was higher for obese (2.60%) than non-obese children (1.32%). The SDDs for bone mass were similar for obese and non-obese children. An obese child must lose or gain more absolute fat and lean mass than a non-obese child to be confident that the change is not a reflection of measurement error. Overall, SDD values for fat, lean, and bone mass are low.

    Sex differences and maturation-associated variation in fitness and motor coordination were examined in children aged 8-9 years (n = 128, 67 girls). Assessments included stature and body mass, two-component body composition, percentage of predicted adult stature (as an index of biological maturation), and motor performance and coordination (Körperkoordinationstest für Kinder). Compared to girls, boys were less advanced in maturation status, possessed larger fat mass, demonstrated superior performances in six tests of fitness, and obtained one superior score on the Körperkoordinationstest für Kinder. After controlling for somatic maturation, sex differences persisted in the two multivariate domains: motor performance and motor coordination.

    Objective: Obesity increases cardiac diseases by increasing tendency to atherosclerosis. Our aim was to define epicardial adipose tissue thickness, and its related factors in obese children. Methods: Total of 94 patients were divided into obesity with metabolic syndrome (MS) (n=30), obesity without MS (n=33), and control (n=31) groups. Auxological values with fasting glucose, fasting insulin, alanine transaminase, serum lipid levels, and high sensitive C-reactive protein levels were evaluated. Epicardial adipose tissue thickness, interventricular septum thickness and left ventricular mass were measured by echocardiography. Findings: Weight, body mass index, waist circumference, insulin, alanine transaminase, and high sensitive C-reactive protein values were markedly higher in obesity group when compared with controls (P<0.001). Epicardial adipose tissue thickness was 0.64±0.23 cm in obesity with MS; 0.60±0.20 cm in obesity without MS, and 0.27±0.12 cm in control group (P<0.001). Interventricular septum thickness and left ventricular mass values were markedly high in obesity without MS group (P<0.001 and P=0.002). Conclusion: Our study has indicated that obesity has unfavorable effects on heart starting in the adolescence. PMID:25755863

    This retrospective study evaluated the clinical features and findings in bacterial cultures and in microscopic examination of vaginal secretions in 80 prepubertal girls, aged 2–12 years, with vulvovaginitis. Vaginal secretions were obtained directly from the vagina with a sterile catheter carefully inserted into the vagina. Pathogenic bacteria were isolated in 36% of cases. In 59% of these cases the isolated pathogen was group A ß-haemolytic streptococcus. Candida was not found in any of the patients. The finding of leucocytes in vaginal secretions as an indicator for growth of pathogenic bacteria had a sensitivity of 83% and a specificity of 59%. Antimicrobial treatment should therefore be based on bacteriological findings of vaginal secretions and not on the presence of leucocytes alone. PMID:12651758

    2015-11-01

    The aim of this study is to describe the experience of a group of mothers with obese children, regarding how early bond affects the relationship that both have with food and this, in turn, impacts on childhood obesity. The present study has a qualitative, exploratory and descriptive design. The sample consists of five chilean women between 22 and 39 years old, with obese children between 2 and 4 years old. In-depth interviews were carried out and open coding strategy was used as method of analysis. Results show a tendency of mothers to establish insecure attachment relations, difficulties of tuning and expression of affection, and a predominance of a permissive parenting style around food. This has important implications for prevention and treatment of obesity, focusing on the attachment bond between mother and child.

    There are widespread differences in overweight/obesity prevalence in children, and understanding the reasons for this is very important. The present study aims: (I) to conduct a meta-analysis on overweight/obesity prevalence in Portuguese children; (II) to identify differences in biological and behavioural characteristics between normal-weight and overweight/obese children; and (III) to investigate the importance of individual- and school-level correlates of variation in children’s BMI using multilevel modelling. A search was done for all published papers including Portuguese children during the last decade; further, 686 Portuguese children (9–11 years old) were sampled and their BMI, family income, maturity offset, nutritional habits, physical activity, sedentariness, sleep time, and school environment information were collected. Results showed a stabilization of overweight/obesity during the last decade, 30.6% (95%CI: 0.287–0.34) for boys, 28.4% (95%CI: 0.23–0.35) for girls, and 30.3% (95%CI: 0.27–0.34) for boys and girls together. Differences between weight groups were only found in individual-level biological traits. The multilevel analysis did not identify significant contributions of school-level variables to children’s BMI variation. In conclusion, no increase was found in the prevalence of overweight/obesity among Portuguese children since 2000. Normal-weight and overweight/obese children only differ in individual-level characteristics, and school context variables were not related to variation in BMI. PMID:25372884

    The purpose of the study was to identify the economic differences in familial, physiological, psychological, and lifestyle characteristics associated with overweight and obese children in South Korea. A total of 407 overweight and obese children participated in the study. The obesity rate was 69.0% and the prevalence of metabolic syndrome (MS) was 33.3% in the low-income bracket, and the prevalence of MS was 27.2% for the population. The children in the low-income group were more prone to have poor eating behavior and more likely to spend more than 2 hr viewing television. They also were more likely to have lower self-esteem and more depressive symptoms. School nurses should understand that risk factors for childhood obesity are more prevalent in low-income groups, which will eventually aggravate health disparities between socioeconomic status groups. Therefore, prevention programs for childhood obesity, which target high-risk groups of such children need to be developed and prioritized.

    Childhood obesity when associated with serum lipoprotein changes triggers atherosclerosis. Evidences suggest that the atherosclerotic process begins in childhood and that the extent of early atherosclerosis of the aorta and coronary arteries can be associated with lipoprotein levels and obesity. Furthermore, many studies in childhood demonstrate an important relationship between parameters of insulin sensitivity, body fat distribution, and the development of lipid abnormalities. This review focuses on the most recent findings on the relationship between obesity, dyslipidemia, and cardiovascular risk in children. PMID:25663838

    Obesity is a complex public health issue. Recent data indicate the increasing prevalence and severity of obesity in children. Severe obesity is a real chronic condition for the difficulties of long-term clinical treatment, the high drop-out rate, the large burden of health and psychological problems and the high probability of persistence in adulthood. A staged approach for weight management is recommended. The establishment of permanent healthy lifestyle habits aimed at healthy eating, increasing physical activity and reducing sedentary behavior is the first outcome, because of the long-term health benefits of these behaviors. Improvement in medical conditions is also an important sign of long-term health benefits. Rapid weight loss is not pursued, for the implications on growth ad pubertal development and the risk of inducing eating disorders. Children and adolescents with severe obesity should be referred to a pediatric weight management center that has access to a multidisciplinary team with expertise in childhood obesity. This article provides pediatricians a comprehensive and evidence based update on treatment recommendations of severe obesity in children and adolescents.

  18. Childhood obesity: bringing children's rights discourse to public health policy.

    Childhood obesity is widely understood as a public health issue, but is not commonly understood from a legal perspective. Children's rights discourse can add significant empowerment to public health-based policy, which alone lacks effectiveness in the face of commercial and other counteracting influences. The United Nations Convention on the Rights of the Child has the potential to be used by advocates for children's health to facilitate child health policies pertaining to the issue of childhood obesity. This is because children's rights, as defined in the articles of the convention, establish the essential conditions required by children to achieve optimal health and wellbeing. A rights-based approach may improve children's welfare by encouraging a less fragmented approach to the issue of childhood obesity. The articles of the convention can be used as a template for interdisciplinary collaboration, with a more coherent outcome possible. By articulating childhood obesity as a children's rights issue--not just a public health issue--a more effective strategy for addressing the problem can be developed and implemented.

    Obesity, elevated blood pressure (BP) and arterial stiffness are risk factors for cardiovascular disease. A strong relationship exists between obesity and elevated BP in both children and adults. Obesity and elevated BP in childhood track into adult life increasing the risk of cardiovascular disease in adulthood. Ambulatory BP is the most precise measure to evaluate the BP burden, whereas carotid-femoral pulse wave velocity (cfPWV) is regarded as the gold standard for evaluating arterial (i.e. aortic) stiffness. These measures might contribute to a better understanding of obesity's adverse impact on the cardiovascular system, and ultimately a better prevention and treatment of childhood obesity. The overall aim of the present PhD thesis is to investigate arterial stiffness and 24-hour BP in obese children and adolescents, and evaluate whether these measures are influenced by weight reduction. The present PhD thesis is based on four scientific papers.  In a cross-sectional design, 104 severe obese children and adolescents with an age of 10-18 years were recruited when newly referred to the Children's Obesity Clinic, Holbæk University Hospital, and compared to 50 normal weighted age and gender matched control individuals. Ambulatory BP was measured, and cfPWV was investigated in two ways in respect to the distance measure of aorta; the previously recommended length - the so called subtracted distance, and the currently recommended length - the direct distance. In a longitudinal design, the obese patients were re-investigated after one-year of lifestyle intervention at the Children's Obesity Clinic in purpose of reducing the degree of obesity. In the cross-sectional design, the obese group had higher measures of obesity, while matched for age, gender and height, when compared to the control group. In the longitudinal design, 74% of the 72 followed up obese patients experienced a significant weight reduction. CfPWV was dependent on the method used to measure the

    To evaluate the growth-stimulating effects of short- and long-term treatment with recombinant human growth hormone (rhGH) in growth-retarded children with chronic renal failure (CRF), 103 prepubertal children with CRF on conservative treatment (n = 74) or dialysis (n = 29) were treated with rhGH for up to 5 yr. rhGH treatment persistently increased standardized height (+ 1.6 SD scores) and predicted adult height (+7.7 cm, Tanner method) during the first 3 treatment years (P < 0.001 versus baseline), followed by percentile parallel growth during continued treatment. Both standardized height and predicted adult height were significantly more increased in conservatively treated than in dialyzed children (P < 0.001). Age, GFR, target height, and prestudy growth rate were identified as independent predictors of the response to rhGH treatment during the first and second treatment year. GFR and target height were positively correlated with the change in height SD score and the change in absolute or age-standardized height velocity. Age affected the growth response depending on which outcome measure was used: Although the first-year change in height SD score was inversely correlated with age, the change in absolute height velocity was independent of age, and the change in standardized height velocity was positively correlated with age. The growth response during the first treatment year positively predicted the long-term response. In conclusion, the short- and long-term growth response to rhGH treatment in prepubertal growth-retarded children with CRF is significantly affected by age, GFR, target height, and the pretreatment growth rate. Therefore, rhGH should be preferably started at a young age, and early in the course of CRF.

    To prevent obesity in middle age, early precautions and interventions are required during childhood. Therefore, it is very important to accurately evaluate the degree of overweight in children. Body mass index (BMI) is widely used worldwide in adults, but not in children. Because standard BMI, which is calculated using the average height and weight for age, changes widely during growth, a constant cut-off point cannot be set for children. An international unified method defining childhood obesity has not been established. In many countries, BMI-for-age percentile (BMI%) value or Z (standard deviation) score is used, whereas in Japan, the percentage of overweight (POW), which is the modified weight-for-height method, is used. We compared BMI% values with POW values obtained using the anthropometric data of elementary and junior high school students based on the Japanese school survey conducted in 2000 and found that the values for the degree of overweight were significantly different between the two methods. It became clear that tall students were easily defined as being overweight, whereas short students tended to be evaluated as being underweight when using BMI%. POW method seemed to be more appropriate than BMI% for school-age children. Abdominal obesity, excess visceral adipose tissue (VAT), is highly associated with obesity-related complications. Waist circumference (WC) is now accepted as an appropriate guide to VAT accumulation. The cut-off value of WC defining excess VAT is 80 cm at the umbilical level in Japanese school-age children. It is not easy to decide the obesity criteria and optimum WC in school-age children. Childhood obesity should be discussed more internationally.

    The secreted hepatokine fetuin-A emerges as an independent predictor of type 2 diabetes in adulthood. The overall aims of this study were: (1) to investigate the associations of fetuin-A with adiposity and insulin resistance, as well as its relationship with adipokines, in prepubertal children, and, (2) to evaluate whether, in prepubertal obesity, serum fetuin-A levels may either change or predict the responsiveness to an educational-based weight excess reduction program. We studied 200 prepubertal children (boys/girls: 89/111; Tanner stage 1; age: 5-13 years), included in a cohort of 44,231 adolescents who participated in an extensive Italian school-based survey. According to Cole's criteria, 100 individuals were lean (boys/girls: 57/43) and 100 obese (boys/girls: 54/46). A subset of 53 obese individuals (boys/girls: 28/25; age: 6-12 years) were also evaluated after a weight excess reduction program. Serum fetuin-A, leptin, total and high molecular weight adiponectin levels, as well as homeostasis model assessment of insulin resistance were assessed. When compared with lean, obese children exhibited higher ( p < 0.0001) fetuin-A concentrations, without differences between sex. Fetuin-A was positively associated with adiposity, homeostasis model assessment of insulin resistance, and leptin levels. In multivariate analysis, the associations between fetuin-A and leptin or homeostasis model assessment of insulin resistance lost the significance after adjustment for BMI Z-score, which, in turn, represented an independent determinant of fetuin-A (R (2)adj 0.327; p < 0.0001). Notably, after weight excess reduction program, fetuin-A levels dropped ( p < 0.0001 vs. basal). Interestingly, no significant differences of fetuin-A concentrations between responders and no responders were found. In prepubertal children, fetuin-A represents an early marker of adiposity, and its reduction after lifestyle intervention may partly contribute to the beneficial effects

    Background There is emerging evidence linking diabetes with periodontal disease. Diabetes is a well-recognized risk factor for periodontal disease. Conversely, pro-inflammatory molecules released by periodontally-diseased tissues may enter the circulation to induce insulin resistance. While this association has been demonstrated in adults, there is little information regarding periodontal status in obese children with and without type 2 diabetes (T2D). We hypothesized that children with T2D have higher rates of gingivitis, elevated salivary inflammatory markers, and an altered salivary microbiome compared to children without T2D. Methods Three pediatric cohorts ages 10–19 years were studied: lean (normal weight—C), obese (Ob), and obese with T2D (T2D). Each subject completed an oral health survey, received a clinical oral examination, and provided unstimulated saliva for measurement of inflammatory markers and microbiome analysis. Results The diabetes group was less likely to have had a dental visit within the last six months. Body mass index (BMI) Z-scores and waist circumference/height ratios were similar between Ob and T2D cohorts. The number of carious lesions and fillings were similar for all three groups. The gingival index was greater in the T2D group compared to the Ob and C groups. Although salivary microbial diversity was minimal between groups, a few differences in bacterial genus composition were noted. Conclusions Obese children with T2D show a trend toward poorer oral health compared to normal weight and obese children without T2D. This study characterizes the salivary microbiome of children with and without obesity and T2D. This study supports a modest link between T2D and periodontal inflammation in the pediatric population.

    Cytokines are considered to be involved in obesity-related metabolic diseases. Study objectives are to determine the heritability of circulating cytokine levels, to investigate pleiotropy between cytokines and obesity traits, and to present genome scan results for cytokines in 1030 Hispanic children enrolled in VIVA LA FAMILIA Study. Cytokine phenotypes included monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor-alpha (TNF-alpha), leptin, adiponectin, soluble intercellular adhesion molecule-1 (sICAM-1), transforming growth factor beta 1 (TGF-beta1), C-reactive protein (CRP), regulated upon activation, normal T-cell expressed and secreted (RANTES) and eotaxin. Obesity-related phenotypes included body mass index (BMI), fat mass (FM), truncal FM and fasting serum insulin. Heritabilities ranged from 0.33 to 0.97. Pleiotropy was observed between cytokines and obesity traits. Positive genetic correlations were seen between CRP, leptin, MCP-1 and obesity traits, and negative genetic correlations with adiponectin, ICAM-1 and TGF-beta1. Genome-wide scan of sICAM-1 mapped to chromosome 3 (LOD=3.74) between markers D3S1580 and D3S1601, which flanks the adiponectin gene (ADIPOQ). Suggestive linkage signals were found in other chromosomal regions for other cytokines. In summary, significant heritabilities for circulating cytokines, pleiotropy between cytokines and obesity traits, and linkage for sICAM-1 on chromosome 3q substantiate a genetic contribution to circulating cytokine levels in Hispanic children.

    Childhood obesity rates have risen dramatically over the past few decades. Although obesity has been linked to poorer neurocognitive functioning in adults, much less is known about this relationship in children and adolescents. Therefore, we conducted a systematic review to examine the relationship between obesity and obesity-related behaviors with neurocognitive functioning in youth. We reviewed articles from 1976 to 2013 using PsycInfo, PubMed, Medline and Google Scholar. Search terms included cognitive function, neurocognitive function/performance, executive function, impulsivity, self-regulation, effortful control, cognitive control, inhibition, delayed gratification, memory, attention, language, motor, visuo-spatial, academic achievement, obesity, overweight, body mass index, waist-hip ratio, adiposity and body fat. Articles were excluded if participants had health problems known to affect cognitive functioning, the study used imaging as the only outcome measure, they were non-peer-reviewed dissertations, theses, review papers, commentaries, or they were non-English articles. Sixty-seven studies met inclusion criteria for this review. Overall, we found data that support a negative relationship between obesity and various aspects of neurocognitive functioning, such as executive functioning, attention, visuo-spatial performance, and motor skill. The existing literature is mixed on the effects among obesity, general cognitive functioning, language, learning, memory, and academic achievement. Executive dysfunction is associated with obesity-related behaviors, such as increased intake, disinhibited eating, and less physical activity. Physical activity is positively linked with motor skill. More longitudinal research is needed to determine the directionality of such relationships, to point towards crucial intervention time periods in the development of children, and to inform effective treatment programs.

    Purpose To analyze the associations among the degrees of nonalcoholic fatty liver disease (NAFLD) by ultrasonography and metabolic syndrome, degrees of obesity in children, and degrees of parental obesity. Methods A total of 198 children with obesity who visited a pediatric obesity clinic were prospectively enrolled in this study. The severity of NAFLD based on ultrasonography was classified into no, mild, moderate, or severe NAFLD group. The degree of obesity based on the percentage over standard weight for height per sex was classified into mild, moderate, or severe. Results Of 132 patients evaluated for the degree of NAFLD and metabolic syndrome, the p-value of correlation between the two factors was 0.009. Therefore, metabolic syndrome might significantly affect the degree of NAFLD. Of 158 patients evaluated for the degree of NAFLD and the degree of obesity, the p-value of correlation between the two factors was 0.122. Of 154 patients evaluated for the degree of obesity and father's obesity, the p-value was 0.076. Of 159 patients evaluated for the degree of obesity and mother's obesity, the p-value was 0.000, indicating that mother's obesity could significantly affect the degree of obesity in children. Of 142 patients evaluated for the degree of obesity and metabolic syndrome, the p-value was 0.288. Conclusion Metabolic syndrome might significantly affect the degree of nonalcoholic fatty liver in children. In addition, mother's obesity might be a significant factor that affects the degree of obesity in children. PMID:27738602

    Obesity is a multifactorial disease due to the influence of both genetic and environmental factors. Parents of 886 obese patients (427 boys and 459 girls, aged 1-18 years) were investigated by means of a questionnaire in order to study the factors associated with the onset of obesity in children and the relationship to genetic background. At presentation obese patients had a very high mean ideal body weight percent (IBW%) (154 +/- 19%, median 152%, range 120-246). A significantly higher mean IBW% was found in children of obese parents (one obese parent: 158 +/- 21%, median 156%, range 120-246; two obese parents 160 +/- 18%, median 158%, range 123-226) in comparison to children of normal weight parents (150 +/- 18%; median 147%, range 120-235; p = 0.0001 for children of one or two obese parents versus children of normal weight parents). Parents of 414 subjects (46.7%) (Group A) answered that obesity had always been present. The remaining 472 parents (53.3%) (Group B) stated that obesity had had a beginning at a mean age of 5.3 +/- 2.6 years (median 5.0 years, range 1.0-17.0). No difference was found in age at presentation, sex distribution, birth weight and number of obese parents between the two groups. Parents in Group B recalled an event associated with obesity onset in 197 cases (health event: 119 answers, psycho-social event: 78 answers). Genetic background did not influence this pattern of feedback. In conclusion, parents of obese subjects seek medical advice when obesity is severe. Pediatricians should exert strict surveillance on weight from a very young age. The recall in 22% patients of health or psychosocial events at the onset of obesity emphasizes that medical counselling is important when the occurrence of particular events in life may cause erroneous eating habits.

    Background Nutrients, hormones and growth factors in dairy foods may stimulate growth hormone (GH), insulin-like growth factor I (IGF-I), and raise the ratio of IGF-I to its binding protein, IGFBP-3. We conducted pilot studies in Mongolia and Massachusetts to test the extent to which milk intake raised somatotropic hormone concentrations in prepubertal children. Methods In Ulaanbaatar, we compared plasma levels before and after introducing 710 ml daily whole milk for a month among 46 10–11 year old schoolchildren. In a randomized cross-over study in Boston, we compared plasma hormone levels of 28 6–8 year old girls after one week of drinking 710 ml lowfat (2%) milk with their hormone levels after one week of consuming a macronutrient substitute for milk. Results After a month of drinking whole milk, Mongolian children had higher mean plasma levels of IGF-I (p < 0.0001), IGF-I/IGFBP-3 (p < 0.0001), and 75th percentile of GH levels (p = 0.005). After a week of drinking lowfat milk, Boston girls had small and non-significant increases in IGF-1, IGF-1/IGFBP-3 and GH. Conclusion Milk drinking may cause increases in somatotropic hormone levels of prepubertal girls and boys. The finding that milk intake may raise GH levels is novel, and suggests that nutrients or bioactive factors in milk may stimulate endogenous GH production. PMID:17900364

    Evidence suggests variability in adult obesity risk at a small-scale geographic area is associated with differences in neighborhood socioeconomic status (SES). However, the extent to which geographic variability in child obesity is associated with neighborhood SES is unknown. The objective of this paper was to estimate risk of child obesity associated with multiple census tract SES measures and race within a large urban U.S. county. Height, weight, age, sex, medical insurance type and census tract residence were obtained for 6-18 year old children (n=8616) who received medical care at a health plan in King County, Washington, in 2006. Spatial analyses examined the individual risk of obesity (BMI > or = 95th percentile) with 2000 US census tract measures of median household income, home ownership, adult female education level, single parent households, and race as predictors. Conditional autoregressive regression models that incorporated adjacent census tracts (spatial autocorrelation) were applied to each census tract variable, adjusting for individual variables. We found that in adjusted spatial models, child obesity risk was significantly associated with each census tract variable in the expected direction: lower household income, lower home ownership, and for each 10% increase in less educated women, and single parent households, as well as non-white residents. In a spatial model including all variables, the SES/race variables explained approximately 24% of geographic variability in child obesity. Results indicated that living in census tracts with social disadvantage defined by multiple different measures was associated with child obesity among insured children in a large U.S. urban county. These results contribute new information on relationships between broader social and economic context and child obesity risk using robust spatial analyses.

    Obesity is a cardiovascular risk factor in adults. Poorly is known about effect of obesity on cardiovascular system in children. Mechanical properties of a great elastic trunk, the common carotid artery (CCA) and endothelium function of the brachial artery were studied in 130 obese children (age: 12 +/- 3 years, body mass index (BMI): 29 +/- 5.5 kg/m2, without hypertension (115 +/- 19/58 +/- 8 mmHg). These patients had a vascular high resolution echographical analysis. Cross sectional compliance (CSC), cross sectional distensibility (CSD) and incremental elastic modulus (Einc) were analysed at the CCA site. The brachial artery dilation was measured after hyperthemia (flow mediated dilation, FMD), an endothelium dependent function and after sublingually glyceryl trinitrate (GTNMD), an independent endothelium function. Fat mass composition and distribution were assessed by dual-energy X-ray absorptiometry in 70 patients. In 50 obese patients an oral glucose tolerance test was done to determine insulin resistance. The obese children had significantly lower CSC and CSD than the healthy controls (respectively 0.12 +/- 0.04 vs 0.14 +/- 0.05 mm2.mmHg-1; p < 0.05 and 0.5 +/- 0.2 vs 0.8 +/- 0.4 mmHg(-1).10(-2); p < 0.001). Obese children had higher value than the controls for Einc (2.4 +/- 0.4 vs 1 +/- 0.24 mmHg.10(3); p < 0.001) that correlated poorly with fasting insulin concentrations (r = 0.34; p < 0.06) and BMI (r = 0.34; p < 0.01). FMD was significantly lower in obese children than in controls (6 +/- 3 vs 8 +/- 4%, p < 0.01) without modification of GTNMD (17 +/- 6 vs 18 +/- 7%, NS). These two parameters were respectively correlated with the android fat distribution (r = 0.36; p < 0.01; r = 0.49; p < 0.001). The CCA stiffness of obese children is linked to the amount of the overweight and to insulin resistance. The android fat distribution is related to endothelium dysfunction.

    Purpose This study was performed to evaluate the quality of sleep in snoring obese children without obstructive sleep apnea (OSA); and to study the possible relationship between sleep interruption and gastroesophageal reflux (GER) in snoring obese children. Methods Study subjects included 13 snoring obese children who were referred to our sleep lab for possible sleep-disordered breathing. Patients underwent multichannel intraluminal impedance and esophageal pH monitoring with simultaneous polysomnography. Exclusion criteria included history of fundoplication, cystic fibrosis, and infants under the age of 2 years. Significant association between arousals and awakenings with previous reflux were defined by symptom-association probability using 2-minute intervals. Results Sleep efficiency ranged from 67-97% (median 81%). A total of 111 reflux episodes (90% acidic) were detected during sleep, but there were more episodes per hour during awake periods after sleep onset than during sleep (median 2.3 vs. 0.6, p=0.04). There were 279 total awakenings during the sleep study; 56 (20.1%) of them in 9 patients (69.2%) were preceded by reflux episodes (55 acid, 1 non-acid). In 5 patients (38.5%), awakenings were significantly associated with reflux. Conclusion The data suggest that acid GER causes sleep interruptions in obese children who have symptoms of snoring or restless sleep and without evidence of OSA. PMID:27066445

    OBJECTIVE: To test the hypothesis that obese normotensive children and adolescents present impaired cardiac autonomic control compared to non-obese normotensive ones. METHODS: For this cross-sectional study, 66 children and adolescents were divided into the following groups: Obese (n=31, 12±3 years old) and Non-Obese (n=35, 13±3 years old). Obesity was defined as body mass index greater than the 95th percentile for age and gender. Blood pressure was measured by oscillometric method after 15 minutes of rest in supine position. The heart rate was continuously registered during ten minutes in the supine position with spontaneous breathing. The cardiac autonomic control was assessed by heart rate variability, which was calculated from the five-minute minor variance of the signal. The derivations were the index that indicates the proportion of the number of times in which normal adjacent R-R intervals present differences >50 miliseconds (pNN50), for the time domain, and, for the spectral analysis, low (LF) and high frequency (HF) bands, besides the low and high frequencies ratio (LF/HF). The results were expressed as mean±standard deviation and compared by Student's t-test or Mann-Whitney's U-test. RESULTS: Systolic blood pressure (116±14 versus 114±13mmHg, p=0.693) and diastolic blood pressure (59±8 versus 60±11mmHg, p=0.458) were similar between the Obese and Non-Obese groups. The pNN50 index (29±21 versus 43±23, p=0.015) and HF band (54±20 versus 64±14 normalized units - n.u., p=0.023) were lower in the Obese Group. The LF band (46±20 versus 36±14 n.u., p=0.023) and LF/HF ratio (1.3±1.6 versus 0.7±0.4, p=0.044) were higher in Obese Group. CONCLUSIONS: Obese normotensive children and adolescents present impairment of cardiac autonomic control. PMID:25119757

    Objective. To evaluate the effectiveness of a 12-month multicomponent obesity prevention intervention. Setting. 9 elementary schools in Santiago, Chile. Subjects. 6–8 y old low-income children (N = 1474). Design. Randomized controlled study; 5 intervention/4 control schools. We trained teachers to deliver nutrition contents and improve the quality of PE classes. We determined % healthy snacks brought from home, children's nutrition knowledge, nutritional status, duration of PE classes, and % time in moderate/vigorous activity (MVA). Effectiveness was determined by comparing Δ BMI Z between intervention and control children using PROCMIXED. Results. % obesity increased in boys from both types of schools and in girls from control schools, while decreasing in girls from intervention schools (all nonsignificant). % class time in MVA declined (24.5–16.2) while remaining unchanged (24.8–23.7%) in classes conducted by untrained and trained teachers, respectively. In boys, BMI Z declined (1.33–1.24) and increased (1.22–1.35) in intervention and control schools, respectively. In girls, BMI Z remained unchanged in intervention schools, while increasing significantly in control schools (0.91–1.06, P = 0.024). Interaction group ∗ time was significant for boys (P < 0.0001) and girls (P = 0.004). Conclusions. This intervention was effective in controlling obesity, but not preventing it. Even though impact was small, results showed that when no intervention is implemented, obesity increases. PMID:24872892

    There is a worldwide increase of overweight and obesity not only in adults, but also in children. Data used to estimate prevalence are, however, collected in differing age groups using nonstandardized measurements and instruments and refer to differing time periods. Moreover, various reference systems to classify overweight and obesity exist, thus, adding to the difficulty in comparing countries. In this paper, these problems are discussed in detail. The most common reference systems are introduced, and their impact on the estimation of the prevalence of overweight and obesity is demonstrated. Based on available data of the global situation, maps that depict the worldwide distribution of the prevalence of overweight and obesity in children and adolescents are presented. Finally, these maps will be discussed critically. Although it may be assumed that these data are collected according to the best quality standards available, the lack of a unified protocol to conduct studies on childhood obesity hampers the comparability of data between countries. Obvious limitations in that respect are the use of different reference systems, differing sampling schemes, and differing age groups. More subtle limitations result from, e.g., different measurement methods, including self-reported weight and height.

    The aim of this prospective case control study is to determine CD4(+), CD25(+), and FoxP3(+) T regulatory cells (Tregs) and T helper cells (Ths) in obese, asthmatic, asthmatic obese, and healthy children. Obese (n = 40), asthmatic (n = 40), asthmatic obese (n = 40), and healthy children (n = 40) were included in this study. Blood samples collected from children were marked with CD4, CD25, ve Foxp3 in order to detect Tregs and Ths by flow cytometric method. Statistical analyses were performed. p ≤ 0.05 was chosen as meaningful threshold. Tregs exhibiting anti-inflammatory nature were significantly lower in obese (0.16 %; p ≤ 0.001), asthmatic (0.25 %; p ≤ 0.01), and asthmatic obese (0.29 %; p ≤ 0.05) groups than control group (0.38 %). Ths were counted higher in asthma group than control (p ≤ 0.01) and obese (p ≤ 0.001) groups. T cell immunity plays important roles in chronic inflammatory diseases such as obesity and asthma pathogeneses. Decreased numbers of Tregs found in obese, asthmatic, and asthmatic obese children might represent a challenge of these cells.

    Objective To evaluate sonographic measurements of visceral and subcutaneous fat in children, and to investigate the usefulness of preperitoneal fat (PF) and the abdominal wall fat index (AFI) as parameters to determine visceral fat and presence of nonalcoholic fatty liver disease (NAFLD) in obese children. Materials and Methods A case-control study of a sample including 44 children (22 cases and 22 controls) matched by sex and age. The Student t test and the Fisher exact test were utilized in the descriptive and bivariate analysis. Results The sonographic parameters evaluated - subcutaneous cell tissue, PF and intraperitoneal fat, and NAFLD - presented high statistical association with body mass index. NAFLD was observed in eight obese patients (36.36%), and PF and AFI were the variables with highest statistical significance, with p < 0.0001. Conclusion Ultrasonography is useful tool in the differentiation and quantification of visceral and subcutaneous fat in children. The measures of PF and AFI are useful in the assessment of visceral fat and NAFLD in obese children. PMID:25741071

  2. Antibiotic administration and the development of obesity in children.

    PubMed

    Antibiotics are the most common prescription drugs administered at the paediatric age, however their administration can cause unwanted problems. Among these issues, antibiotic-induced gut microbiota dysbiosis has appeared as an emerging issue and has been associated with obesity. This problem is particularly relevant in children because they are frequently treated with antibiotics. Early development of obesity increases the risk of adult obesity, which is associated with the emergence of very severe clinical problems. Dysbiosis induced in the first periods of life can have the most relevant practical consequences because a decrease in the number of microbes and their substitution with other microbes dramatically modifies the development of the immune system as well as glucose and lipid metabolism. Unfortunately, not all of the mechanisms that could explain the relationship between gut microbiota modification and the development of obesity have been defined. Consequently, no definitive therapeutic approach has been elucidated. Probiotics and prebiotics could play a role in treating microbial dysbiosis because the addition of specific bacterial strains has been associated with normal weight and has been demonstrated to be useful in clinical conditions other than obesity that are caused by microbiota disruption. Considering that antibiotics are commonly prescribed and that obesity is increasing in paediatric patients, further studies specifically designed to evaluate how to disrupt the relationship between antibiotics and dysbiosis are urgently needed. Presently, paediatricians have to consider dysbiosis to be a new and serious reason for the judicious use of antibiotics in clinical practice.

    Sleep is an important modulator of neuroendocrine function and glucose metabolism in children as well as in adults. In recent years, sleep curtailment has become a hallmark of modern society with both children and adults having shorter bedtimes than a few decades ago. This trend for shorter sleep duration has developed over the same time period as the dramatic increase in the prevalence of obesity. There is rapidly accumulating evidence from both laboratory and epidemiological studies to indicate that chronic partial sleep loss may increase the risk of obesity and weight gain. The present article reviews laboratory evidence indicating that sleep curtailment in young adults results in a constellation of metabolic and endocrine alterations, including decreased glucose tolerance, decreased insulin sensitivity, elevated sympathovagal balance, increased evening concentrations of cortisol, increased levels of ghrelin, decreased levels of leptin, and increased hunger and appetite. We also review cross-sectional epidemiological studies associating short sleep with increased body mass index and prospective epidemiological studies that have shown an increased risk of weight gain and obesity in children and young adults who are short sleepers. Altogether, the evidence points to a possible role of decreased sleep duration in the current epidemic of obesity.

    Obesity in childhood is associated with the presence of complications that can undermine health immediately or in the long term. Several conditions, such as pulmonary or orthopedic complications are strictly associated with the severity of overweight, since they are directly associated to the mechanic stress of fat tissue on the airways or on the bones. Other conditions, such as metabolic or liver complications, although increasing with the extent of overweight, are associated with insulin resistance, which can be modulated by different other factors (ethnicity, genetics, fat distribution) and can occur in overweight children as well. No less important are psychological correlates, such as depression and stigma, which can seriously affect the health related quality of life. Pediatric services for the care of childhood obesity need to be able to screen overweight and obese children for the presence of physical and psychological complications, which can be still reversed by weight loss. This article provides pediatricians a comprehensive update on the main complications in obese children and adolescents and their treatment.

  6. Ecological Risk Model of Childhood Obesity in Chinese Immigrant Children

    2015-01-01

    Chinese Americans are the largest and fastest growing Asian American subgroup, increasing about one-third during the 2000s. Despite the slender Asian stereotype, nearly one-third of 6-to-11 years old Chinese American children were found to be overweight (above the 85th percentile in BMI). Importantly, unique and severe health risks are associated with being overweight/obese in Chinese. Unfortunately, Chinese immigrant children have been neglected in the literature on obesity. This review aimed to identify factors at various levels of the ecological model that may place Chinese immigrant children at risk for being overweight/obese in the U.S. Key contextual factors at the micro-, meso-, exo-, macro- and chronosystem were identified guided by Bronfenbrenner’s ecological systems theory. The corresponding mediating and moderating processes among the factors were also reviewed and proposed. By presenting a conceptual framework and relevant research, this review can provide a basic framework for directing future interdisciplinary research in seeking solutions to childhood obesity within this understudied population.

    Objective To evaluate the association between obesity indices and blood pressure (BP) at 4 years of age, in each sex, and to quantify to which extent this association is mediated by inflammation and insulin resistance (IR). Materials and Methods We studied 1250 4-year-old children selected from the population-based birth cohort Generation XXI. Associations between body mass index (BMI) z-score and waist-to-height ratio (WHtR), office BP, inflammation (high sensitivity C-reactive protein) and IR (HOMA-IR index) were assessed. Path Analysis, a modified multivariate regression approach, was applied to test causal models and quantify direct and indirect effects of predictors of systolic (SBP) and diastolic BP (DBP). Results SBP and DBP increased significantly with BMI and WHtR in both sexes. There was a strong direct association (explaining 74.1-93.2% of the total association) of both measures of adiposity with SBP, in both sexes. This association was additionally indirectly mediated by IR, particularly regarding WHtR (20.5% in girls and 9.4% in boys). Mediation by inflammation did not reach statistical significance in either sex. Regarding DBP, the direct effect of adiposity was strong (>95% for BMI and WHtR in boys) and the mediation by IR was much smaller in boys than in girls. Discussion The direct association between adiposity and BP in healthy 4-year-old children is strong and IR plays an important mediating role. The strength of effects of IR and inflammation suggests sex differences in the complex interplay between BP, adiposity and inflammation. PMID:26125190

    Objectives To investigate the prevalence of obesity among elementary school children and to examine the association between obesity and caries activity in the mixed dentition stage. Methods This cross-sectional study was conducted in King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia between September 2014 and June 2015 using a multi-stage stratified sample of 915 elementary school children (482 boys, 433 girls) in Jeddah, Saudi Arabia. Anthropometric measurements, consisting of height, weight, body mass index (BMI), and waist circumference (WC), were obtained. Children were classified as underweight/healthy, overweight, or obese and as non-obese or obese according to their BMI and WC, respectively. Each child’s caries experience was assessed using the decay score in the primary and permanent teeth. Results Based on BMI, 18% of children were obese, 18% were overweight, and 64% were underweight/normal. Based on WC, 16% of children were obese, and 84% were non-obese. Girls had a significantly higher prevalence of obesity based on WC measurements (p<0.001), but not BMI. Children enrolled in private schools had a significantly higher prevalence of obesity (p<0.05) than those in public schools. For primary and permanent teeth combined, children with higher BMI and WC had a lower prevalence of caries (p<0.05). Conclusion The prevalence of obesity was high among male and female elementary school children. Overall caries activity was inversely proportional to BMI and WC. PMID:27874156

    Severe obesity in childhood is increasing in prevalence and is associated with considerable morbidity. Studies into pediatric obesity have focused largely on interventions that do not necessarily target the unique biologic or psychological underpinnings for the weight gain in the individual child or adolescent. Outcomes show modest improvement and are of questionable benefit for patients with severe obesity. Although weight is a commonly used outcome, other psychological and metabolic parameters including normalization of physical activity and eating behaviors should be primary outcome goals. The durability of weight loss is often limited by physiologic systems that are evolutionarily designed to promote weight gain. Drug therapies for children are limited, as is their effect on weight and metabolism. Existing drugs that are incidentally found to cause weight loss through off-target effects are being actively investigated for obesity indications. Bariatric surgery results in the most significant weight reduction, but it is associated with potential morbidity and long term data are not available for adolescents undergoing this procedure. As understanding of the biologic and psychosocial contributors to eating behaviors and body weight regulation increases, multifaceted and targeted behavioral, pharmacological, and surgical treatment algorithms should be developed and applied to target the underlying pathways involved for the individual child or adolescent with severe obesity.

    The link between sleep duration and obesity has been well established in adults, but several epidemiological studies revealed inconsistent findings in adolescents and younger children. This study aimed to investigate the relationship between sleep length and obesity in Saudi students. A total of 5,877 Saudi students, boys (55.2%) and girls (44.8%), aged between 10 and 19 years were randomly selected from elementary, intermediate, and secondary schools in different regions of Riyadh. A questionnaire on sleep behaviors was given. Anthropometry included BMI and waist and hip circumferences. Sleeping obesity in both boys and girls (all age categories) (odds ratio = 1.25-1.38, 95% confidence intervals = 1.02-1.89). Overall prevalence of overweight and obese were higher among those sleeping intermittently (18.68%) than those sleeping continuously (14.5%) (P = 0.024). Short sleep duration and poor sleep quality are significantly associated with obesity among Arab youth. Further studies need to employ more objective measures of sleep, such as actigraphy, and examine the mechanism of these associations.

    Children with Down syndrome have a higher risk for developing obesity. The primary care provider can assist the family in preventing or managing obesity by recognizing the physiological and behavioral factors that place children and adolescents with Down syndrome at increased risk to become obese, and establishing a screening and management plan early to prevent or treat excess weight gain. By using adapted strategies, the negative physiological and psychological outcomes associated with obesity may be lessened or avoided in this specific population.

    A questionnaire-based investigation was performed on 325 Japanese school children with Down syndrome ages 6 to 18. Data on height and body weight, eating habits, physical activity for these children were obtained through their parents. Proportion of obese children was higher among these subjects than the average for Japanese children (34.3% and 7.47% respectively, for the ages from 6 to 14). We examined characteristics of eating habits and physical activities between the obese group (obesity index greater than 20% above the average of Japanese school children) and the non-obese group. Obesity started to increase in the obese group around age 7. The obese group tended to have had a greater intake of sweets, juice and total foods in their preschool days, but unexpectedly had been physically more active in their primary school days.

    Objective: In this study, our aim was to determine cardiovascular risk and cardiac function in prediabetic obese children and adolescents. Methods: The study was conducted on 198 obese children and adolescents 6-18 years of age. Anthropometric measurements, blood pressure measurements, oral glucose tolerance test, lipid profile, and HbA1c levels of patients were assessed. Prediabetes was defined according to American Diabetes Association criteria. Left ventricular mass index (LVMi), carotid intima-media thickness (c-IMT), and tissue Doppler measurements records were used. Results: LVMi was found to be significantly higher in the prediabetes group (p=0.03). There were no statistically significant differences in right ventricular tissue Doppler measurements between the prediabetic and non-prediabetic groups. Left ventricular tissue Doppler measurements were significantly higher in the prediabetes group: LVEEM (left ventricular E/e ratio) (p=0.04); LVEM (left ventricular myocardial velocity cm/s) (p=0.035). LVMi was found to positively correlate with triglyceride level, diastolic blood pressure, waist circumference, body weight standard deviation score and to negatively correlate with high-density lipoprotein cholesterol (p=0.043, r=0.15; p=0.039, r=0.15; p=0.025, r=0.17; p=0.009, r=0.19; p=0.038, r=-0.15, respectively). LVEM was correlated with glucose (p=0.046, r=0.15) and LVEEM was correlated with systolic blood pressure (p=0.035, r=0.15). In linear regression analysis for clinical cardiovascular risk factors, fasting glucose level was the best predictor of LVEM. Conclusion: In this study, deterioration of cardiac function in prediabetic obese children and adolescents was shown. We recommend determining cardiovascular risk and cardiac dysfunction at early stages in prediabetic obese children and adolescents. PMID:26759114

    2008-03-01

    Sedentary lifestyle patterns in children and adolescents, i.e. playing digital games, using computers and especially watching television, have been associated with obesity. However, not all sedentary behaviour has shown the same relevance to, and relationship with, obesity. Therefore, we conducted a review including published studies found in PubMed and other medical journals, dated between January 1990 and April 2007. The ages of the children and adolescents who were the object of the study ranged between 2 and 18 years. For the purpose of this paper, we selected cross-sectional, longitudinal and intervention studies. Sufficient evidence exists to recommend setting a limit to the time spent watching TV, especially for younger children. However, video games and computers do not represent such a high risk compared to watching TV, when they do not replace physical activity too much. In fact, there is no evidence to suggest that sedentary behaviour displaces physical activity levels. Mechanisms that explain the link between sedentariness and obesity are also discussed. Finally, future studies should take into account important mediators such as socioeconomic status and family structure.

    The dramatic world-wide trend towards increasing body weight seems to be less obvious in the Japanese population. The aim of this study is to extract potentially useful information regarding childhood and adolescence obesity in Japan from series of mean height and mean body mass index between 1948 and 2003. Mean values for height and weight of Japanese boys and girls aged 5+ to 17+ years were obtained from the "Reports on School Health Survey", Ministry of Education, Culture, Sports, Science and Technology, comprising approximately 4.5% of all children and adolescents in Japan between 1948 and 2003. The data were fitted by the Preece and Baines model (Preece & Baines 1978) in order to obtain estimates of the age of peak height velocity (APHV) and final height. Isochrones for height and BMI were calculated based upon measurements that were obtained at the same chronological ages at different historic epochs. The APHV as estimated by Preece & Baines (1978) has decreased from 14.07 to 12.03 years in Japanese boys, and from 11.80 to 9.92 years in Japanese girls, indicating that the tempo of child and adolescent maturation (maturational tempo) has accelerated. Body height increased by 10.1 cm in near adult 17+ year old Japanese males and by 5.7 cm in 17+ year old Japanese females since 1948. Due to the acceleration and the earlier attainment of adult stature, isochrones for height tend to diverge for prepubertal ages and to converge for postpubertal ages. The same is true for weight. Body weight has increased by 11.8 kg in near adult males, and by 4.4 kg in near adult females. Also BMI has increased since 1948. But in contrast to height and weight, the rise in BMI only reflects the acceleration of the maturational tempo. Tempo-conditioned isochrones for BMI are almost horizontal, and even tended to temporarily decrease during the 60ies and the 70's. The BMI of Japanese children and adolescents dramatically contrasts the recent and historic BMI changes in the Western

    Obesity potentially arising from viral infection is known as 'infectobesity'. The latest reports suggest that adenovirus-36 (Adv36) is related to obesity in adults and children. Our aim was not only to determine the Adv36 seropositivity in both obese and non-obese children and adults, but also to investigate correlations between antibody positivity and serum lipid profiles. Both Adv36 positivity and tumour-necrosis-factor-alpha, leptin and interleukin-6 levels were detected in blood samples collected from 146 children and 130 adults by ELISA. Fasting plasma triglycerides, total cholesterol and low-density lipoprotein levels were also measured. Adv36 positivity was determined to be 27·1% and 6% in obese and non-obese children and 17·5% and 4% in obese and non-obese adults, respectively. There was no difference with regard to total cholesterol, low-density lipoprotein, triglyceride, tumour-necrosis-factor-alpha and interleukin-6 levels (P > 0·05). However, there was a significant difference between groups in terms of leptin levels (P < 0·05). We determined the prevalence of Adv36 positivity in obese children and adults. Our results showed that Adv36 may be an obesity agent for both adults and children, parallel with current literature data. However, the available data on a possible relationship between Adv36 infection and obesity both in children and adults do not completely solve the problem.

    This study analyzes peer effects on childhood obesity using data from the first two waves of the IDEFICS study, which applies several anthropometric and other measures of fatness to approximately 14,000 children aged two to nine participating in both waves in 16 regions of eight European countries. Peers are defined as same-sex children in the same school and age group. The results show that peer effects do exist in this European sample but that they differ among both regions and different fatness measures. Peer effects are larger in Spain, Italy, and Cyprus--the more collectivist regions in our sample--while waist circumference generally gives rise to larger peer effects than BMI. We also provide evidence that parental misperceptions of their own children's weight goes hand in hand with fatter peer groups, supporting the notion that in making such assessments, parents compare their children's weight with that of friends and schoolmates.

    Background and Objectives: Although the prevalence of childhood obesity has increased significantly in Saudi Arabia, parents are unable to appreciate obesity in their child. The objective of the study was to identify the percentage of parents who misclassify the status of child's weight, and determine whether there is a difference between those parents whose children are overweight and obese and those with children of normal weight. Materials and Methods: This cross-sectional study included 601 children aged 6-10 years. The children were recruited from the primary schools located in Al-Qassim, Saudi Arabia. The body mass index of the children was assessed in the school, and their parents responded to a self-administered questionnaire which contained questions on parental perception of the children's weight/obesity status. Data were entered and analyzed using SPSS. Results: Parents with overweight/obese children had significantly more misclassification than those with normal weight children. Ninety percent of parents of the 81 overweight children misclassified and reported that their child had normal weight, while 65% of parents of the 61 obese children, misclassified the child's weight status. Conclusions: The level of misclassification of children's weight status by parents is high. Saudi parents with overweight and obese children do not recognize their child's weight status. Parents’ awareness of childhood obesity and its negative health impact needs to be improved. PMID:27625586

    While mounting evidence suggests that sleep plays an important role in the etiology of obesity, the underlying pathogenic pathways are complex and unresolved. Experimental sleep deprivation studies demonstrate sympathovagal imbalance, indicative of diminished parasympathetic activity and/or heightened sympathetic activity, is consequent to poor sleep. Further, obese children exhibit sympathovagal imbalance, particularly during the night, compared to non-obese children. The question remains whether sympathovagal imbalance is one potential pathophysiological pathway underlying the association between sleep and obesity. The aim of the present study was to examine whether sympathovagal imbalance contributed to the association between sleep and obesity in children. Participants included 564 children aged 10 to 12 years (M = 11.67, SD = 0.95; 43.5% girls) from the QUALITY Cohort, a longitudinal study of children at-risk for the development of obesity. While children were at-risk due to confirmed parental obesity status, 57.7% of children were of normal body mass index (5-85th percentile). Sleep duration, sleep timing, and sleep disturbances were based on child- and parent-report. Anthropometrics were measured for central adiposity (waist circumference) and body composition (body mass index, fat mass index). Sympathovagal imbalance was derived from heart rate variability spectral analyses. Estimated path coefficients revealed that sympathovagal imbalance partially contributed to the association between poor sleep (later bedtimes, sleep-disordered breathing) and obesity. These findings highlight the importance of better understanding sympathovagal imbalance and its role in the etiology and maintenance of obesity. Future research should consider investigating nocturnal sympathovagal balance in youth.

  4. Assessment of obese children and adolescents: a survey of pediatric obesity-management programs.

    This article provides descriptive information on the assessments conducted in stage 3 or 4 pediatric obesity-management programs associated with National Association of Children's Hospital and Related Institutions hospitals enrolled in FOCUS on a Fitter Future. Eighteen institutions completed a survey that considered the following assessments: patient/family medical history; physical examination; blood pressure; body size and composition; blood chemistry; aerobic fitness; resting metabolic rate; muscle strength and flexibility; gross motor function; spirometry; sedentary behavior and physical activity; dietary behavior and nutrition; and psychological assessments. Frequency distributions were determined for each question. Overall, the results indicate that most programs that participated in this survey were following 2007 Expert Committee assessment recommendations; however, a variety of measurement tools were used. The variation in assessment tools, protocols, etc is partially caused by the program diversity dictated by personnel, both in terms of number and duties. It also shows the challenges in standardizing methodologies across clinics if we hope to establish a national registry for pediatric obesity clinics. In addition to providing a better understanding of the current assessment practices in pediatric obesity-management programs, the results provided herein should assist other clinics/hospitals that are developing pediatric obesity programs.

    In the last decades, obesity and chronic kidney disease (CKD) have increased worldwide, in parallel. This article focuses on the current issues of obesity on renal damage, with special emphasis on what happens at pediatric ages. While obesity has been linked closely with type 2 diabetes mellitus and hypertension, reduced insulin sensitivity is a direct mechanism for renal damage. The pathophysiologic mechanisms on renal damage include glomerular hyperfiltration and hypertrophy, hypercellularity and broadening of the mesangial regions, while the lack of sensitivity to insulin increases the effects of angiotensin II, exacerbates proteinuria and induces the production of inflammatory cytokines. Many epidemiological studies have documented the relationship of increased BMI with the development of ERC, but most of these studies have been conducted in adults. In children, the information is scarce, but is consistent with findings in adults. In contrast, there are studies which show that interventions aimed to improve weight loss and limit renal damage and proteinuria is reduced, the blood pressure and glomerular filtration rate. Allthe above make us think on the need to improve efforts to reduce the prevalence of obesity from the early stages of life, which could reduce the number of patients with CKD in the future.

    Background The Government of Guam passed Public Law 28-87, which established the collection of child Body Mass Index (BMI) measurements in the Guam Department of Education (GDOE). This paper aimed to analyze the BMI data and report the childhood obesity prevalence on Guam. Methods Secondary analysis was performed on a repeated cross-section of 106,827 children in the GDOE from 2010 to 2014. Age- and sex-specific prevalence estimates and 95% Confidence Intervals (CI) by weight status were calculated for each year. Test for trends in the high weight status were performed. Results The childhood obesity prevalence was 23.1% (95% CI, 22.9%–23.4%). It declined from 23.6% (95% CI, 23.1%–24.1%) in 2010–2011 to 22.6% (95% CI, 22.1%–23.0%) in 2013–2014 (p=.007). Conclusion Childhood obesity on Guam has declined, though it remains higher than the U.S. Mainland. Continued BMI data collection is needed to monitor childhood obesity and measure the impact of Public Law 28-87. PMID:25981088

    The prevalence of obesity among Mexicans is alarming in both the child and adult populations. The objective of this study was to determine the levels of overweight, obesity and abdominal obesity in pre-school (PS), elementary (ES), and middle high (MHS) public school children from Tijuana. From February to April of 2011, a bietapic random sample was selected by cluster method of 30 PS, 30 ES, and 30 MHS children. And a sample of 30 groups for each level was chosen. Twenty elementary teachers and eight graduate students were trained at one central location on how to take anthropometric measurements using a portable scale, a stadiometer, and a measuring tape to determine weight, height, and waist circumference. Body Mass Index values were computed and compared to age/gender BMI percentiles according to WHO criteria. Waist circumference for-age at the 90th percentile from NHANES III (Mexican-American) was used to define abdominal obesity. The sample was composed of 646 PS children, 961 ES children, and 1,095 MHS children. Their ages ranged from 4- 16 years. Results showed an overall prevalence of overweight and obesity in younger than 5y preschool children (> 2 SD) of 23.1%, in ≥ 5 y PS (> 1 SD) of 33.8%, in ES children of 46.3%, and in MHS children of 41.9%. Abdominal obesity in PS children was 18%, in ES children was 16.7%, and in MHS children was 15.2%. These results warrant immediate and comprehensive actions to prevent a critical public health problem in Mexico.

    Summary Methods The incidence of obesity is increasing worldwide, especially in countries with accelerated economic growth. We determined the prevalence of and associations between overweight/ obesity and cardiovascular risk factors in pre-pubertal (seven- to 11-year-old) schoolchildren (both genders, n = 198) in Luanda, Angola. Biochemical (fasting blood) and clinical examinations were obtained in a single visit. Data are reported as prevalence (95% confidence intervals) and association (r, Pearson). Results Prevalence of overweight/obesity was 17.7% (12.4–23.0%), high blood pressure (BP < 90% percentile) was 14.6% (9.7–19.5%), elevated glucose level was 16.7% (11.5–21.9%) and total cholesterol level < 170 mg/dl (4.4 mmol/l) was 69.2% (62.8–75.6%). Significant associations between body mass index (BMI) and systolic and diastolic BP (r = 0.46 and 0.40, respectively; p < 0.05) were found. No association between BMI and elevated glucose or cholesterol levels was found. Conclusion The prevalence of cardiovascular risk factors was high in pre-pubertal schoolchildren in Angola and fat accumulation was directly associated with blood pressure increase but not with other cardiovascular risk factors.

    The present study was aimed to find out the prevalence of overweight and obesity and its associated factors among Bengalee children and adolescents in the Kolkata, India. A total of 1061 Bengalee school children and adolescents (610 boys and 451 girls) participated and were divided into three age groups: Group I = 8-11 years; Group II = 12-15 years and Group III = 16-18 years. Overweight and obesity were defined as: Overweight (between ≥85 th and <95 th percentile) and obesity (≥95 th percentile). Multivariate regression analyses (adjusted for age and sex) of body mass index (BMI) revealed that about 18% (R2 = 0.185) of total variance of BMI could be explained by monthly family income, participants think obese, consumption of too much junk foodstuffs, breakfast skip, extra consumption of salt, and computer hours. Sedentary lifestyles, including increasing fast food preferences may be responsible for increasing occurrence of pediatric and adolescent obesity in this population.

  10. Raising healthy children: Moral and political responsibility for childhood obesity.

    PubMed

    Purcell, Megan

    2010-12-01

    Childhood obesity and chronic disease rates continue to climb, but policy and programme responses are mainly limited to education and awareness activities. These encourage individuals to make responsible lifestyle choices. Regulation and environmental change have a minor role, as they involve more intrusive roles for government, invading traditionally private domains of nutrition and physical activity. But to address children's health needs, today's emphasis on self-management is inappropriate. Children, especially the very young, are dependent and vulnerable. I describe why the current public health strategies, with their political and moral foundations, remain ineffective. The foundations are based primarily upon the traditional liberal understanding of the public/private divide, while neglecting to recognize the legal obligations and implications of the United Nations Convention on the Rights of the Child and theories of justice and citizenship as they apply to children.

    Introduction To determine the metabolic profile in a group of obese children in Morocco. Methods The BMI, the waist circumference, the blood pressure and metabolic parameters in 73 children (37 obese and 36 normal) were compared. Results 80% of obese children had abdominal obesity (p <0.0001). For systolic blood pressure among children who have a higher value than the 95th percentile, 85.7% were obese and 14.3% children are normal children. For diastolic blood pressure, 83.34% of obese children had higher diastolic blood pressure values in the 95th percentile and 16.6% of normal children have a higher value than the 95th percentile (p=0.013). No obese child had hyperglycemia. The prevalence of metabolic syndrome was 21.6%. Conclusion Obesity is number one risk of cardiovascular disease for children. Early detection can help for an appropriate care. PMID:25977740

    OBJECTIVE: In individuals with asthma, obesity induces the production of leptin and is associated with disease severity. Our objective was to evaluate the levels of serum leptin and their effect on Th1/Th2 balance in obese and non-obese children with asthma, as well as to investigate the association between serum leptin levels and clinical outcomes. METHODS: We evaluated 50 atopic children with physician-diagnosed moderate-to-severe persistent asthma and 20 controls. The children with asthma were divided into two groups, by body mass index percentile: obese (n = 25) and non-obese (n = 25). From all subjects, we collected peripheral blood samples in order to determine the levels of leptin, IFN-γ, and IL-4. Asthma severity was assessed by an asthma symptom score, and the results were correlated with the parameters studied. RESULTS: Serum leptin levels were significantly higher in the obese asthma group than in the non-obese asthma group, as well as being significantly higher in the children with asthma than in the controls, whereas IFN-γ levels were significantly higher and IL-4 levels were significantly lower in the obese asthma group than in the non-obese asthma group. In addition, the obese asthma group showed higher asthma symptom scores and significantly lower FEV1 (% of predicted) than did the non-obese asthma group. There was a significant positive correlation between leptin and IFN-γ levels only in the obese asthma group. CONCLUSIONS: Although leptin is involved in the pathogenesis of asthma in obese and non-obese children, its effect is more pronounced in the former. In the presence of high leptin levels, only obese children with asthma exhibited Th1 polarization, with higher IFN-γ levels and greater asthma severity. PMID:24310629

    Researchers and health practitioners are becoming increasingly concerned with the problems associated with obesity among children and adolescents. Obesity tends to persist into adulthood and to be associated with a variety of physical and psychological problems. Treatment approaches used to date are generally impotent, but some promising short-term results have been achieved with some forms of dietary counseling, exercise programs, total environmental management, and behavior therapy. But even with these strategies, clinically significant weight loss is rare and advances during treatment are rarely maintained. Radical departures from current treatment strategies are needed in the form of more structured and intensive treatments, family involvement, and training in problem solving. Closer adherence to sound scientific methodology might at least provide a foundation from which more effective treatments might be developed. PMID:626257

    IMPORTANCE Obesity affects nearly one sixth of U.S. children and results in alterations to body composition and physiology that can affect drug disposition, possibly leading to therapeutic failure or toxicity. The depth of available literature regarding obesity’s effect on drug safety, pharmacokinetics (PK) and dosing in obese children is unknown. OBJECTIVE To perform a systematic literature review describing the current evidence of the effect of obesity on drug disposition in children. EVIDENCE REVIEW We searched the Medline, Cochrane, and Embase databases (January 1970–December 2012) and included studies if they contained clearance, volume of distribution, or drug concentration data in obese children (age ≤18 years). We compared exposure and weight-normalized volume of distribution and clearance between obese and non-obese children. We explored the relationship between drug physicochemical properties and clearance and volume of distribution. FINDINGS Twenty studies met inclusion criteria and contained pharmacokinetic data for 21 drugs. The median number of obese children studied per drug was 10 (range 1–112), ages ranged from 0–29 years. Dosing schema varied and were based on a fixed dose (n=6, 29%), body weight (n=10, 48%), and body surface area (n=4, 19%). Clinically significant pharmacokinetic alterations were observed in obese children for 65% (11/17) of studied drugs. Pharmacokinetic alterations resulted in substantial differences in exposure between obese and non-obese children for 38% (5/13) of drugs. We found no association between drug lipophilicity or Biopharmaceutical Drug Disposition Classification System class and changes in volume of distribution or clearance due to obesity. CONCLUSIONS AND RELEVANCE Consensus is lacking on the most appropriate weight-based dosing strategy. Prospective pharmacokinetic trials in obese children are needed to ensure therapeutic efficacy and enhance drug safety. PMID:25961828

    Background Insulin resistance may be assessed as whole body or hepatic. Objective To study factors associated with both types of insulin resistance. Methods Cross-sectional study of 182 obese children. Somatometric measurements were registered, and the following three adiposity indexes were compared: BMI, waist-to-height ratio and visceral adiposity. Whole-body insulin resistance was evaluated using HOMA-IR, with 2.5 as the cut-off point. Hepatic insulin resistance was considered for IGFBP-1 level quartiles 1 to 3 (<6.67 ng/ml). We determined metabolite and hormone levels and performed a liver ultrasound. Results The majority, 73.1%, of obese children had whole-body insulin resistance and hepatic insulin resistance, while 7% did not have either type. HOMA-IR was negatively associated with IGFBP-1 and positively associated with BMI, triglycerides, leptin and mother's BMI. Girls had increased HOMA-IR. IGFBP-1 was negatively associated with waist-to-height ratio, age, leptin, HOMA-IR and IGF-I. We did not find HOMA-IR or IGFBP-1 associated with fatty liver. Conclusion In school-aged children, BMI is the best metric to predict whole-body insulin resistance, and waist-to-height ratio is the best predictor of hepatic insulin resistance, indicating that central obesity is important for hepatic insulin resistance. The reciprocal negative association of IGFBP-1 and HOMA-IR may represent a strong interaction of the physiological processes of both whole-body and hepatic insulin resistance. PMID:25411786

    As obesity has become more prevalent, the incidence of type 2 diabetes mellitus in children and adolescents has also increased. Obesity during adolescence leads to an increased risk for disease and premature death during adulthood, independent of obesity during adulthood. Obesity is the major risk factor impacting insulin sensitivity. Subjects with insulin resistance are at risk for progression to diabetes. Type 2 diabetes mellitus in obese children and adolescents is frequently asymptomatic. It is essential to identify children at high risk who need aggressive lifestyle modification focused on weight reduction and increased physical activity. Early detection and therapy of obese children and adolescents with type 2 diabetes may reduce the risk of cardiometabolic consequences and other long-term complications in adulthood.

    Background Obesity is a significant public health threat to children in the United States. Aims 1) Determine the prevalence of obesity in a multi-center cohort of children with IBD; 2) Evaluate whether overweight and obese status is associated with patient demographics or disease characteristics. Methods We used data from the ImproveCareNow Collaborative for pediatric IBD, a multi-center registry of children with IBD, collected between April 2007 and December 2009. Children ages 2-18 years were classified into BMI percentiles. Bivariate analyses and multivariate logistic regression were used to compare demographic and disease characteristics by overweight (BMI>85%) and obese (BMI>95%) status. Results The population consisted of 1598 children with IBD. The prevalence of overweight/obese status in pediatric IBD is 23.6%, (20.0% for Crohn's disease (CD) and 30.1% for ulcerative colitis (UC) and indeterminate colitis (IC)). African American race (OR 1.64, 95% CI 1.10-2.48) and Medicaid insurance (OR 1.67, 95% CI 1.19-2.34) were positively associated with overweight/obese status. Prior IBD related surgery (OR 1.73, 95% CI 1.07-2.82) was also associated with overweight and obese status in children with CD. Other disease characteristics were not associated with overweight and obesity in children with IBD. Conclusions Approximately 1/5 of children with CD and 1/3 with UC are overweight or obese. Rates of obesity in UC are comparable to the general population. Obese IBD patients may have a more severe disease course, as indicated by increased need for surgery. Sociodemographic risk factors for obesity in the IBD population are similar to those in the general population. PMID:21910178

    This retrospective medical chart review examined the prevalence of overweight/obesity (≥85th percentile) and obesity (≥95th percentile) in Hispanic foster children aged 2-18 years in Los Angeles, California. Logistic regression was used for boys and girls separately to analyze polyvictimization (i.e., one vs. two or more types of maltreatment), type of maltreatment (abuse vs. neglect), and age-group as risk factors for overweight and obesity. Almost 40% of participants were overweight/obese, with the highest prevalence (47.7%) observed among children aged 12-18. Children aged 6-18 were at an increased risk of overweight/obesity and obesity compared with children aged 2-5. Although polyvictimization has been shown to have adverse health effects, in this study, it was related to slightly lower odds of obesity for boys but was unrelated to high weight for girls. Addressing the obesity epidemic among Hispanic foster children is vital to preventing continued obesity and the development of obesity-related health problems, especially by focusing on important community and family influences.

  15. Is sleep deprivation a contributor to obesity in children?

    PubMed

    Chaput, Jean-Philippe

    2016-03-01

    Chronic lack of sleep (called "sleep deprivation") is common in modern societies with 24/7 availability of commodities. Accumulating evidence supports the role of reduced sleep as contributing to the current obesity epidemic in children and youth. Longitudinal studies have consistently shown that short sleep duration is associated with weight gain and the development of obesity. Recent experimental studies have reported that sleep restriction leads to weight gain in humans. Increased food intake appears to be the main mechanism by which insufficient sleep results in weight gain. Voluntary sleep restriction has been shown to increase snacking, the number of meals eaten per day, and the preference for energy-dense foods. Although the causes of sleep loss in the pediatric population are numerous, more research looking at screen exposure before bedtime and its effects on sleep is needed given the pervasiveness of electronic media devices in today's environment. Health professionals should routinely ask questions about sleep and promote a good night's sleep because insufficient sleep impacts activity and eating behaviors. Future research should examine the clinical benefits of increasing sleep duration on eating behaviors and body weight control and determine the importance of adequate sleep to improve the treatment of obesity.

  16. Mediterranean-style diet reduces metabolic syndrome components in obese children and adolescents with obesity

    2014-01-01

    Background The beneficial effects of the Mediterranean diet have been amply proven in adults with cardiovascular risk factors. The effects of this diet have not been extensively assessed in pediatric populations with obesity, insulin resistance (IR) and metabolic syndrome (MetS). The aim of this study was to assess the efficacy of the Mediterranean style diet (MSD) to decrease cardiovascular risk factors in children and adolescents with obesity. Methods Participants were randomly assigned to a MSD rich in polyunsaturated fatty acids, fiber, flavonoids and antioxidants (60% of energy from carbohydrate, 25% from fat, and 15% from protein, (n = 24); or a standard diet (55% of carbohydrate, 30% from fat and 15% from protein, (n = 25), the caloric ingest was individualized. At baseline and 16-week of intervention, the glucose, triglycerides (TG), total cholesterol (TC), HDL-C, LDL-C were measured as well as the body composition and anthropometric data. The diet compliance was determined by the 24-hour recalls. Paired Student’s t and Macnemar’s test were used to compare effects in biochemical, body composition, anthropometric, and dietary variables. Results The MSD group had a significantly decrease in BMI, lean mass, fat mass, glucose, TC, TG, HDL-C and LDL-C. (p < 0.05); the diet compliance increased consumption of omega 9 fatty acids, zinc, vitamin E, selenium, and decreased consumption of saturated fatty acids (p < 0.05). The standard diet group decrease in glucose levels and frequency of glucose >100 mg/dL (p < 0.05). Conclusion The MSD improves the BMI, glucose and lipid profile in children and adolescents with obesity and any MetS component. PMID:24997634

  17. Appropriate care for children with eating disorders and obesity.

    PubMed

    El-Radhi, A Sahib

    Eating disorders are essentially psychological diseases that are characterised by abnormal eating habits. Anorexia nervosa and bulimia are the most common forms of eating disorders. There is an increased recognition of eating disorders among both men and women, and growing numbers of children and teenagers seeking help for eating disorders. Fear of body-weight gain is central to both anorexia nervosa and bulimia. Before the diagnosis of an eating disorder is made, it is essential to exclude organic diseases that may present with similar symptoms to eating disorders. Management initially should focus on correcting the nutritional deficiencies and dehydration at a paediatric or paediatric gastroenterology department, followed by a multidisciplinary approach. At the other extreme, the prevalence of obesity in children is increasing at an alarming rate, and presents a serious public health challenge.

    The aim of the study was to define the most common causes, symptoms and clinical features of vulvovaginitis in prepubertal girls, and to evaluate treatment success depending on the causative agent involved. The study included 115 girls aged 2-8 (mean 4.8) years, presenting with vulvovaginitis to the Outpatient Clinic for Pediatric and Adolescent Gynecology, Zagreb Children's Hospital, between September 2006 and July 2007. Medical history data were obtained from parents. Vaginal samples were collected for microbiological culture by using cotton-tipped swabs moistened with saline. All samples were referred to microbiology laboratory, where standard microbiological diagnostic procedures were performed. Selective and non-selective media were used. Of 115 study patients, 43 (37.4%) had received antibiotic therapy more than one month prior to their visit to the Clinic, mainly for upper respiratory tract infection. The most common presenting symptom was increased vaginal discharge usually noticed on the pants or diaper, found in 26 of 115 (22.6%) patients, followed by vulvar redness in 16 (13.9%), burning in seven (6.1%), itching in the vulvovaginal area in seven (6.1%), soreness in six (5.2%), odor in three (2.6%) patients, and two or more of these symptoms in another 50 (43.5%) patients. Fifty-nine of 115 children had normal clinical finding on gynecologic examination. Among the remaining 56 children, the most common finding was erythema observed in 19, vaginal discharge in ten, and a combination of discharge and erythema in 13 patients. Of 115 study patients, causative agents were isolated from vaginal culture in 38 (33%) cases. Of these, 21 grew group A beta hemolytic streptococcus, five patients Haemophilus influenzae, three Escherichia coli, two Enterococcus spp., and one each Staphylococcus aureus, Proteus mirabilis, and Streptococcus pneumoniae.

    Epidemiologic and qualitative studies have found that most mothers with overweight preschool children do not think their children are overweight. This might present a challenge for clinicians who wish to address obesity in young children. To understand mothers' perceptions of their overweight children's weight, we conducted semistructured interviews with 21 mothers of overweight preschool children enrolled in Kentucky's Special Supplemental Nutrition Program for Women, Infants, and Children. Although these mothers did not label their children as overweight, they were worried about children's weight, particularly as it related to their emotional well-being. These worries about obesity were reflected in three central tensions that shaped the way mothers perceived their children's weight and informed maternal feeding strategies: (a) nature vs. nurture, (b) medical authority vs. lived experience, and (c) relieving immediate stress vs. preventing long-term consequences. Acknowledging mothers' concerns and tensions might help clinicians communicate more effectively with them about obesity.

    Background Several studies have identified multiple obesity-associated loci mainly in European populations. However, their contribution to obesity in other ethnicities such as Mexicans is largely unknown. The aim of this study was to examine 26 obesity-associated single-nucleotide polymorphisms (SNP) in a sample of Mexican mestizos. Methods 9 SNPs in biological candidate genes showing replications (PPARG, ADRB3, ADRB2, LEPR, GNB3, UCP3, ADIPOQ, UCP2, and NR3C1), and 17 SNPs in or near genes associated with obesity in first, second and third wave GWAS (INSIG2, FTO, MC4R, TMEM18, FAIM2/BCDIN3, BDNF, SH2B1, GNPDA2, NEGR1, KCTD15, SEC16B/RASAL2, NPC1, SFRF10/ETV5, MAF, PRL, MTCH2, and PTER) were genotyped in 1,156 unrelated Mexican-Mestizos including 683 cases (441 obese class I/II and 242 obese class III) and 473 normal-weight controls. In a second stage we selected 12 of the SNPs showing nominal associations with obesity, to seek associations with quantitative obesity-related traits in 3 cohorts including 1,218 Mexican Mestizo children, 945 Mexican Mestizo adults, and 543 Indigenous Mexican adults. Results After adjusting for age, sex and admixture, significant associations with obesity were found for 6 genes in the case-control study (ADIPOQ, FTO, TMEM18, INSIG2, FAIM2/BCDIN3 and BDNF). In addition, SH2B1 was associated only with class I/II obesity and MC4R only with class III obesity. SNPs located at or near FAIM2/BCDIN3, TMEM18, INSIG2, GNPDA2 and SEC16B/RASAL2 were significantly associated with BMI and/or WC in the combined analysis of Mexican-mestizo children and adults, and FTO locus was significantly associated with increased BMI in Indigenous Mexican populations. Conclusions Our findings replicate the association of 8 obesity-related SNPs with obesity risk in Mexican adults, and confirm the role of some of these SNPs in BMI in Mexican adults and children.

    Objective To explore outcomes and measures of success that matter most to 'positive outlier' children who improved their body mass index (BMI) despite living in obesogenic neighborhoods. Methods We collected residential address and longitudinal height/weight data from electronic health records of 22,657 children ages 6–12 years in Massachusetts. We defined obesity “hotspots” as zip codes where >15% of children had a BMI ≥95th percentile. Using linear mixed effects models, we generated a BMI z-score slope for each child with a history of obesity. We recruited 10–12 year-olds with negative slopes living in hotspots for focus groups. We analyzed group transcripts and discussed emerging themes in iterative meetings using an immersion/crystallization approach. Results We reached thematic saturation after 4 focus groups with 21 children. Children identified bullying and negative peer comparisons related to physical appearance, clothing size, and athletic ability as motivating them to achieve a healthier weight, and they measured success as improvement in these domains. Positive relationships with friends and family facilitated both behavior change initiation and maintenance. Conclusions The perspectives of positive outlier children can provide insight into children’s motivations leading to successful obesity management. Practice implications: Child/family engagement should guide the development of patient-centered obesity interventions. PMID:26166630

    Prepubertal unilateral gynecomastia is an extremely rare condition. At present, its etiology and management strategy are not well known. Two unrelated prepubertal boys of ages 8 and 9 who presented with complaints of unilateral enlargement of breast tissue are reported. Physical examination, biochemical, hormonal and oncologic work-up findings were normal. Both patients were treated with peripheral liposuction successfully. Histopathological and immunohistochemical examinations showed benign fibroglandular gynecomastia and intensive (3+) estrogen receptor expression in 100% of periductal epithelial cells. Although an extremely rare and generally benign condition, patients with prepubertal unilateral gynecomastia should have a full endocrine and oncologic work-up. PMID:25541897

    Evidence-based profiling of obesity and overweight in Indigenous Australian children has been poor. This study systematically reviewed evidence of the prevalence and patterns of obesity/overweight, with respect to gender, age, remoteness, and birth weight, in Indigenous Australian children, 0-18 years (PROSPERO CRD42014007626). Study quality and risk of bias were assessed. Twenty-five publications (21 studies) met inclusion criteria, with large variations in prevalence for obesity or overweight (11 to 54%) reported. A high degree of heterogeneity in study design was observed, few studies (6/21) were representative of the target population, and few appropriately recruited Indigenous children (8/21). Variability in study design, conduct, and small sample sizes mean that it is not possible to derive a single estimate for prevalence although two high-quality studies indicate at least one in four Indigenous Australian children are overweight or obese. Four of six studies reporting on gender, found overweight/obesity higher in girls and eight studies reporting on overweight/obesity by age suggest prevalence increases with age with one high quality large national study reporting total overweight/obesity as 22.4% of children aged 2-4 years, 27.5% of those aged 5-9, 38.5% aged 10-14, and 36.3% aged 15-17. Three of four studies, reporting obesity/overweight by region, found lower rates for children living in more remote areas than urban areas.

    This study describes the prevalence of fundamental movement skill (FMS) mastery and advanced skill proficiency among treatment-seeking 6-10-year old children with overweight/obesity. A total of 132 participants (8.4 ± 1.0 years, BMI 24.2 ± 3.1 kg/m(2), 55% female, 76.5% obese) were assessed on 12 FMS and compared with a normative sample. The prevalence of FMS mastery was significantly lower among children categorized as overweight/obese for all skills across all age groups (all p < 0.05). Excluding the leap for 6-7-year olds, differences between the two samples remained when the prevalence of advance skill proficiency was examined for children categorized as overweight/obese. Physical activity programs designed for children with overweight/obesity need to address deficiencies in FMS proficiency as part of an overall strategy to promote physical activity participation.

    In recent years, obesity has become an increasingly important epidemic health problem in children and adolescents. The prevalence of the overweight status in children grew from 5% to 11% from 1960s to 1990s. The epidemic of obesity has been paralleled by an increase in the incidence of chronic kidney disease (CKD) and hypertension. Results of several studies have demonstrated that obesity and metabolic syndrome were independent predictors of renal injury. The pathophysiology of obesity related hypertension is complex, including activation of sympathetic nervous system, renin angiotensin aldosterone system, hyperinsulinemia and inflammation. These same mechanisms likely contribute to the development of increased blood pressure in children. This review summarizes the recent epidemiologic data linking obesity with CKD and hypertension in children, as well as the potential mechanisms. PMID:25949935

    2015-01-01

    Purpose Approximately 1 out of 6 children in the United States is obese. This has important implications for drug dosing and safety, as pharmacokinetic (PK) changes are known to occur in obesity due to altered body composition and physiology. Inappropriate drug dosing can limit therapeutic efficacy and increase drug-related toxicity for obese children. Few systematic reviews examining PK and drug dosing in obese children have been performed. Methods We identified 25 acute care drugs from the Strategic National Stockpile and Acute Care Supportive Drugs List and performed a systematic review for each drug in 3 study populations: obese children (2–18 years of age), normal weight children, and obese adults. For each study population, we first reviewed a drug’s Food and Drug Administration (FDA) label, followed by a systematic literature review. From the literature, we extracted drug PK data, biochemical properties, and dosing information. We then reviewed data in 3 age subpopulations (2–7 years, 8–12 years, and 13–18 years) for obese and normal weight children and by route of drug administration (intramuscular, intravenous, by mouth, and inhaled). If sufficient PK data were not available by age/route of administration, a data gap was identified. Findings Only 2/25 acute care drugs (8%) contained dosing information on the FDA label for each obese children and adults compared with 22/25 (88%) for normal weight children. We found no sufficient PK data in the literature for any of the acute care drugs in obese children. Sufficient PK data were found for 7/25 acute care drugs (28%) in normal weight children and 3/25 (12%) in obese adults. Implications Insufficient information exists to guide dosing in obese children for any of the acute care drugs reviewed. This knowledge gap is alarming, given the known PK changes that occur in the setting of obesity. Future clinical trials examining the PK of acute care medications in obese children should be prioritized. PMID

    This study tested whether children's eating behavior and parental feeding prompts during a laboratory test meal differ among children born at high risk (HR) or low risk (LR) for obesity and are associated with excess child weight gain. At 4 years of age, 32 HR children (mean maternal prepregnancy BMI = 30.4 kg/m(2)) and 29 LR children (maternal BMI = 19.6 kg/m(2)) consumed a test meal in which their eating behavior was assessed, including rate of caloric consumption, mouthfuls/min, and requests for food. Parental prompts for the child to eat also were measured at year 4, and child body composition was measured at ages 4 and 6 years. T-tests, and logistic and multiple regression analyses tested study aims. Results indicated that HR and LR children did not differ in eating rate or parental feeding prompts. Greater maternal BMI, child mouthfuls of food/min, and total caloric intake/min during the test meal predicted an increased risk of being overweight or obese at age 6, whereas greater active mealtime was associated with a reduced risk of being overweight or obese. Regression analyses indicated that only mouthfuls of food/min predicted changes in BMI from 4 to 6 years, and mouthfuls of food/min and gender predicted 2-year changes in sum of skinfolds and total body fat. Thus, a rapid eating style, characterized by increased mouthfuls of food/min, may be a behavioral marker for the development of childhood obesity.

    The purpose of this study was to compare the prevalence of overweight and obesity in typically developing (TD) children, children with developmental coordination disorder (DCD) and balance problems (DCD-BP), and children with DCD without balance problems (DCD-NBP). Two thousand and fifty-seven children (1095 boys, 962 girls) ages 9-12 years were recruited from 18 elementary schools in Taiwan. The Movement Assessment Battery for Children was used to assess motor coordination ability. International cut-off points for body mass index were used to classify participants into the following groups: normal-weight, overweight or obese. Compared with TD children, children in the DCD-BP group were more than twice as likely to be obese (OR=2.28; 95% CI=1.41-3.68). DCD-BP children were also more likely to be obese compared to DCD-NBP children (OR=1.79; 95% CI=1.02-3.16). Boys in the DCD-BP group were more likely to be obese when compared to DCD-BP girls (OR=3.12; 95% CI=1.28-7.57). Similarly, DCD-NBP boys were more likely to be obese when compared to DCD-NBP girls (OR=2.67; 95% CI=1.21-5.89). Children with both DCD and BP were significantly more likely to be obese when compared to TD and DCD-NBP children. From an intervention perspective, the inclusion of regular physical activity, including activities that encourage development of both balance and energy expenditure, may be required to prevent obesity in this population.

    Obesity and the metabolic syndrome are closely related to the cases of cardiovascular disease; they are usually regarded as belonging to the adult population but are seen with increasing frequency in children and adolescents. There is evidence that atherosclerotic lesions occur most often in young people with obesity. The factors involved in this pandemic are manifold and range from genetic-biological to cultural changes. The family and the environment in which the child develops play a key role in the adoption of habits related to diet and physical activity. This problem does not respect borders and cultures but all countries are being affected, even more those of middle-income. State and Society as a whole can play a role oriented to modify this environment. The restriction on sales of unhealthy food and the fight against the sedentary lifestyle are urgently needed to be applied. The impact that these disorders will have in terms of cardiovascular disease, has not yet reached its true dimension.

    2012-09-01

    In this study, we tested the hypothesis that diet composition reported by children before the beginning of an obesity treatment program could be a predicting factor of the clinical outcome. A sample of 138 obese 6-16-year-old children and adolescents were recruited. Anthropometry and dietary habits were recorded. Each patient participated in a multidimensional treatment program in an outpatient obesity public service clinic. Therapy was based on a 6-month educational program on nutrition, lifestyle and physical activity. Children with a lipid intake above 34.7% of total energy had a 2.5 times higher chance of reducing at least 1.5 units of BMI with treatment than children with lower lipid intake. These results suggest that the assessment of habitual diet, in particular diet composition before starting treatment, may help to identify obese children who are more sensitive to intervention and those who need more specific nutritional assistance.

    The increasing trends of blood pressure (BP) in children and adolescents pose great concern for the burden of hypertension-related cardiovascular disease. Although primary hypertension in childhood is commonly associated with obesity, it seems that other factors, such as dietary sodium and exercise, also influence BP levels in children and adolescents. Several studies support that sympathetic nervous system imbalance, impairment of the physiological mechanism of pressure natriuresis, hyperinsulinemia and early vascular changes are involved in the mechanisms causing elevated BP in obese children and adolescents. Under the current evidence on the association of salt intake and BP, dietary sodium restriction appears to be a rational step in the prevention of hypertension in genetically predisposed children and adolescents. Finally, interventional studies show that regular aerobic exercise can significantly reduce BP and restore vascular changes in obese with hypertensive pediatric patients. This article aims to summarize previous studies on the role of obesity, salt intake and exercise on BP in children and adolescents.

    Although obesity presents a serious health problem in children, parents often underestimate their children's overweight and obesity status. Therefore, scientific literature was systematically screened through PubMed and PsycINFO to demonstrate the psychological, social, and cultural processes that underlie this evaluation bias. A total of 37 papers that focused on research conducted in different geopolitical contexts were taken into account. Furthermore, a lexicometric analysis of the papers' conclusions was performed. The findings showed that education plays a key role in promoting parents' awareness and their realistic recognition of their children's weight. Accordingly, adequate educational support for parents should be implemented in all healthcare policies addressing childhood obesity.

    The current literature on obesity in typically developing children shows that the family context, and specifically the way parents parent their children are major determinants of childhood obesity. The influence of these factors on obesity in children with disability, however, remains unclear. A systematic review of the literature was undertaken to identify the parental and parenting risk factors associated with obesity in children and adolescents with disability. Articles were identified through Medline, Academic Search Complete, PsycINFO, ProQuest, ISI, CINAHL, Cochrane and Scopus databases. There was no restriction on publication dates. The inclusion criteria were empirical papers that tested associations between parental and parenting risk factors and obesity in children and adolescents with intellectual and other developmental disabilities. Only 11 studies met the selection criteria and subsequently included in this review. Results suggest that obesity in children and adolescents with disability may be associated with socioeconomic status; parents' body mass index, perception and attitude towards their children's weight and physical activity; and levels of activity in both parents and children. Firm conclusions about these associations cannot be reached, however, due to mixed findings and methodological limitations of the studies. Recommendations for future research are provided.

    Childhood obesity has been a growing concern in recent years. The extent of obesity in various ethnic pediatric populations including Chinese Americans has not been fully explored. In this study, the prevalence of overweight and obesity in a Chinese American pediatric population (6-19 years) was determined through a chart review of 4,695 patients from a large community health center in New York City. Demographic characteristics including sex, age and immigrant status were used in a logistic regression to determine risk factors for obesity in this community. Overall, 24.6% of the children studied were overweight or obese (defined as BMI > or = 85th percentile for age and sex). Among US born boys aged 6-12 years, the combined prevalence of overweight and obesity was found to be as high as 40%. Further studies are needed to understand the complex interplay of factors that contribute to obesity in pediatric immigrant groups.

    Childhood obesity has become a new challenge for healthcare providers. The issue is not limited to certain parts of the world; its prevalence is increasing worldwide. The causes of obesity are poorly understood and continue to be debated and studied. It is a multifactorial disorder which involves dietary, behavioral, environmental as well as genetic factors. The increased consumption of more energy-dense, nutrient-poor foods with high levels of sugar and saturated fats, combined with reduced physical activity, have led to high obesity rates among children. The aim of this study was to assess the effect of dietary intake on the occurrence of childhood obesity, and study other associated factors including the education, occupation and income of parents and the living status. Normal healthy school girls (n =196) and school boys (n = 85) between the age of 6- 15 were recruited for the study. We found that obesity among children in Riyadh City was significantly associated with fast food intake (p = 0.0280). It was also observed that 72.5% of the overweight or obese students consumed fast food at least 4 times/week, and the other 15.9% were taking fast food 1- 3 times/week, while only 11.6% of the same overweight or obese group did not consume any fast food/ week. Father's and mother's occupations were not significantly correlated to their children's body weight. The prevalence of childhood obesity is changing and increasing yearly and is attributed to the nutritional risk factors for the Saudi school-age children. It is interesting to know that most of overweight or obese school students belonged to the families of highincome. Parents must take necessary precautions for the diet of their children and should adopt healthy life style in order to prevent or manage obesity of their children.

    Obesity is a heterogeneous disease with many different subtypes. Epigenetics could contribute to these differences. The aim of this study was to investigate genome-wide DNA methylation searching for methylation marks associated with obesity in children and adolescents. We studied DNA methylation profiles in whole blood cells from 40 obese children and controls using Illumina Infinium HumanMethylation450 BeadChips. After correction for cell heterogeneity and multiple tests, we found that compared to lean controls, 31 CpGs are differentially methylated in obese patients. A greatest proportion of these CpGs is hypermethylated in obesity and located in CpG shores regions. We next focused on severely obese children and identified 151 differentially methylated CpGs among which 10 with a difference in methylation greater than 10%. The top pathways enriched among the identified CpGs included the “IRS1 target genes” and several pathways in cancer diseases. This study represents the first effort to search for differences in methylation in obesity and severe obesity, which may help understanding these different forms of obesity and their complications.

    Adiponectin (Acrp30), its high molecular weight (HMW) oligomers, and Irisin are molecules involved in several metabolic processes. To investigate if these cytokines could represent new metabolic markers, we evaluated the expression of Acrp30 and Irisin in serum of obese children from South Italy affected by different degrees of insulin resistance (IR). The anthropometric and metabolic features were evaluated in 27 obese children versus 13 age-matched controls. The expression of Acrp30, its pattern and Irisin were investigated by ELISA, western blotting and fast protein liquid chromatography. The HOMA index was significantly higher in obese children versus controls, and metabolic syndrome was more prevalent in obese children with elevated IR versus those with normal HOMA (38% vs 16%). Total Acrp30 and HMW oligomers were significantly lower in obese than in control children, and the difference was more pronounced in children with HOMA >3.4. In control and obese children, total Acrp30 and HMW oligomers were inversely related to HOMA (r-0.38, p 0.02; r-0.35, p 0.03). Irisin was significantly higher in obese than in control children, and was inversely correlated with Acrp30 and HMW (r-0.32, p 0.04; r-0.39, p 0.01). The inverse correlation of Acpr30 and HMW oligomers with HOMA indicates that Acpr30 is directly involved in IR status. Moreover, the inverse correlation between Irisin and Acrp30 and, more significantly, between Irisin and HMW oligomers suggests that the two cytokines are closely connected. The use of Acrp30, HMW oligomers and Irisin as predictive factors of IR in obese children remains to be further elucidated.

    Objectives. We estimated racial/ethnic differences in overweight and obesity in a national sample of 3-year-olds from urban, low-income families and assessed possible determinants of differences. Methods. Survey, in-home observation, and interview data were collected at birth, 1 year, and 3 years. We used logistic regression analyses and adjusted for a range of covariates in examining overweight and obesity differentials according to race/ethnicity. Results. Thirty-five percent of the study children were overweight or obese. Hispanic children were twice as likely as either Black or White children to be overweight or obese. Although we controlled for a wide variety of characteristics, we were unable to explain either White–Hispanic or Black–Hispanic differences in overweight and obesity. However, birthweight, taking a bottle to bed, and mother’s weight status were important predictors of children’s overweight or obesity at age 3 years. Conclusions. Children’s problems with overweight and obesity begin as early as age 3, and Hispanic children and those with obese mothers are especially at risk. PMID:17194857

    The consumption of high-fructose corn syrup (HFCS) beverages has increased since the 1970s. At the same time, childhood obesity is on the rise, causing children to be at risk of heart disease, diabetes and other diseases. Healthcare providers have attributed childhood obesity to the consumption of HFCS in the form of beverages. This article will look at the available research and determine if there is scientific evidence underlying the idea that sweetened soft drinks, especially those containing HFCS, could cause or contribute to childhood obesity. A thorough literature search was performed using the ISI Web of Sciences, PubMed and Scopus databases within the years 2006-2012. The search generated 19 results. The articles were screened, and six were deemed eligible: four systematic reviews and two meta-analyses. Two systematic reviews found that there is no relationship between consumption of HFCS beverages and obesity in children. The other two systematic reviews found possible links between HFCS and childhood obesity. The meta-analysis articles found that consumption of HFCS beverages can contribute to childhood obesity, and limitation of sweetened beverages may help decrease obesity in children. Available research studies demonstrate inconclusive scientific evidence definitively linking HFCS to obesity in children.

    The human adenovirus 36 (Ad-36) is causally and correlatively associated in animals and humans, respectively, with increased adiposity and altered metabolic profile. In previous studies, the relationship between Ad-36 seropositivity with obesity was established in adults and children. We evaluated the association of positive antibodies to Ad-36 with obesity and metabolic profile in Mexican children. Seventy-five children with normal-weight and 82 with obesity were studied in this research. All children had a clinic assessment which included weight, height, body circumferences, and skinfold thickness. Laboratory analyzes included triglycerides, total cholesterol, high-density lipoprotein, low-density lipoprotein, and glucose and insulin levels. An enzyme-linked immunosorbent assay (ELISA) was used to determine the antibodies to Ad-36 in the serum samples. The overall Ad-36 seroprevalence was 73.9%. Ad-36 seropositivity had a higher prevalence in obese children than in normal weight group (58.6 versus 41.4%, P = 0.007). Ad-36 seropositivity was associated with obesity (OR = 2.66, P = 0.01) and high-density lipoprotein <40 mg/dL (OR = 2.85, P = 0.03). The Ad-36 seropositive group had greater risk of 4 metabolic abnormalities compared with those children without none alteration. In summary, Ad-36 seropositivity was associated with obesity and low HDL-c levels in the sample of children studied. PMID:24324491

    Background Breast feeding appears to play a role in determining obesity and abdominal obesity during childhood, specifically in children with a history of low birth weight. Objective The purpose of this study is to investigate the relation of breast-feeding with either of abdominal obesity and obesity among Iranian school children. Materials and Methods A total of 1184 students (625 girls and 559 boys), aged 10 to 13 years old, were selected from 112 governmental elementary schools in Iran. Height, weight, waist circumference and blood pressure were measured using standard instruments and a pretested standardized questionnaire was performed for compiling information about family economics and educational level, first–degree family history of obesity, history of breast feeding, food pattern and birth weight, as well. Results 13.68% (n = 160) of students had a history of low birth weight, and 26.41% of them had abdominal obesity. Of all participants, 22.04% were overweight and 5.32% were obese which was more prevalent in girls than in boys (P = 0.03). First-degree family history of obesity (P = 0.001), excessive gestational weight gain (P = 0.001) and birth weight (P = 0.01) were significantly correlated with the prevalence of obesity and abdominal obesity during childhood. Moreover the prevalence of abdominal obesity in children with low birth weight was significantly correlated with breast feeding (P = 0.04); But this relation was not significantly about obesity in our participants (P = 0.9). Furthermore duration of breast feeding was significantly and inversely correlated with obesity and abdominal obesity in schoolchildren with low birth weight (P = 0.01). Conclusions The results suggest that Breast feeding and its long-term consequences were important factors for preventing metabolic syndrome criteria in childhood and later years of life span. With regard to the increasing prevalence of obesity in children, more research is urgently needed to clarify whether

    Introduction Racial/ethnic differences in recent obesity trends have not been reported among young low-income children. The purpose of this study is to examine trends in obesity prevalence from 1998 through 2011 by race/ethnicity among low-income children aged 2–4 years. Methods The study was based on measured weight and height records of 29,040,851 participants of federally funded health and nutrition programs from 30 states and the District of Columbia, which provided data each year from 1998 through 2011. More than 80% of data were collected through the Special Supplemental Nutrition Program for Women, Infants, and Children, and about 50% of eligible children were included. In 2014, joinpoint regression was used to identify the inflection years when significant changes in obesity trends occurred and piecewise logistic regression was used to examine annual changes in obesity prevalence before and after the inflection years controlling for age, sex, and race/ethnicity. Results The overall obesity prevalence increased from 13.05% in 1998 to 15.21% in 2003, and decreased slightly to 14.74% in 2011. The increasing trends among non-Hispanic white, non-Hispanic black, and Hispanic children began decreasing in 2003. Asian/Pacific Islander was the only racial/ethnic group with a continual decreasing trend in obesity prevalence from 1998 (14.34%) through 2011 (11.66%). Among American Indian/Alaska Native children, obesity prevalence consistently increased from 16.32% in 1998 to 21.11% in 2011, although the annual increases slowed since 2001. Conclusions The study findings indicate modest recent declines in obesity prevalence for most racial/ethnic groups of low-income children aged 2–4 years. However, obesity prevalence remains high.

    The purpose of this study was to identify the prevalence of overweight and obesity among 5,158 school-age children and to evaluate the effectiveness of a walking program to encourage physical activity among children in Western Pennsylvania. According to the National Health and Nutrition Examination Survey (NHANES), obesity in school-age children affects approximately 19% of children 6-11 years old in the United States (Centers for Disease Control and Prevention 2010c ). Data were collected over six years. The results of the study revealed the prevalence of obesity and overweight was higher than the national averages: 36% versus 20%. The results also revealed the walking program to be beneficial in reducing students' prevalence of obesity and overweight and keeping them moving.

    Historically, the anthropometric assessment of nutritional welfare programs has been targeted to assess nutritional deficiencies based on weight-to-age and height-to-age indicators. Recently, given the increase on childhood obesity, it has been also recommended the measurement of indicators of obesity (i.e., weight-to-height) and central obesity (i.e., waist circumference). However, the agreement of these indicators in preschool children is unclear. The aims of this study were: (1) assess the nutritional status of children attending the Chilean National Nursery Schools Council Program (JUNJI); (2) assess the agreement between general and central obesity anthropometric measurements in these children. In 574 girls and 580 boys, 3.0 to 5.9 years old, we measured: weight, height, waist and hip circumference, and five skinfolds. We used the WHO 2006 growth standards to estimate Z-scores. We defined general obesity as WHZ or BAZ= 2, and central obesity as waist circumference > or =90 percentile of NHANES III. The participants were on average slightly shorter but considerably heavier and obese than the reference populations. Prevalence of general obesity was close to 16% with both indicators while prevalence of central obesity reached 15%. There was good agreement among general obesity indicators and central obesity indicators (Kappa = 0.6-0.7). In summary, we found a high prevalence of obesity and central obesity among Chilean preschool children beneficiaries of a welfare program. At this age, there was a good agreement among general obesity indicators and central obesity indicators. These results suggest that waist circumferences measurements should not be incorporated to the program.

    Childhood obesity is reaching epidemic proportions throughout the world; however, little is known on the nutritional status of children with disabilities. To address this issue, medical records of 748 children aged 18 years or younger receiving physical therapy during 2004-2005 at a privately sponsored free rehabilitation clinic in Punta Arenas, Patagonia, Chile were abstracted. Data included demographic, clinical, and anthropometric information recorded at the first visit. As a comparison, height and weight were also collected in 215 children attending local schools. Nutritional status was calculated as body mass index (above 6 years of age) or evaluated by growth curves (6 years of age or below) as undernourished, normal, overweight, obese, or morbidly obese. Logistic regression was used to determine risk factors for obesity in these children. Overall, a significant difference in nutritional status between disabled and non-disabled children was found (P<0.001). Children with disabilities had a higher prevalence of both below and above normal weight than non-disabled children. Risk factors for obesity included increasing age and living with a grandparent independent of other socioeconomic factors. Compared with normal children, risk of obesity was doubled for those with developmental delays [odds ratio (OR): 1.96; 95% confidence interval (CI): 1.16-3.34] and neurological disorders (OR: 2.58, 95% CI: 1.26-5.29), whereas individuals with cerebral palsy were less than half as likely to be obese than non-disabled children (OR: 0.46, 95% CI: 0.20-1.03). We conclude that overnutrition continues to be a problem for both disabled and non-disabled children in Patagonia. Programs to increase physical activity and improve nutrition are needed in this isolated part of the world.

    Objective Being overweight or obese is one of the most common reasons that children and adolescents are teased at school. We carried out a study in order to investigate: i) the relation between weight status and school bullying and ii) the relation between weight status categories and types of victimization and bullying in an outpatient sample of Italian children and adolescents with different degrees of overweight from minimal overweight up to severe obesity. Participants/Methods Nine-hundred-forty-seven outpatient children and adolescents (age range 6.0–14.0 years) were recruited in 14 hospitals distributed over the country of Italy. The participants were classified as normal-weight (N = 129), overweight (N = 126), moderately obese (N = 568), and severely obese (N = 124). The nature and extent of verbal, physical and relational bullying and victimization were assessed with an adapted version of the revised Olweus bully-victim questionnaire. Each participant was coded as bully, victim, bully-victim, or not involved. Results Normal-weight and overweight participants were less involved in bullying than obese participants; severely obese males were more involved in the double role of bully and victim. Severely obese children and adolescents suffered not only from verbal victimization but also from physical victimization and exclusion from group activities. Weight status categories were not directly related to bullying behaviour; however severely obese males perpetrated more bullying behaviour compared to severely obese females. Conclusions Obesity and bullying among children and adolescents are of ongoing concern worldwide and may be closely related. Common strategies of intervention are needed to cope with these two social health challenges. PMID:26606393

    Today, the most pathogenic therapy of GH deficiency is hGH replacement therapy. Replacement hGH therapy a highly effective method of growth correction in children with GH deficiency, but further investigations are necessary for timely detection of disturbances of other organs and systems. The authors reported that hGH therapy supressed thyroid and adrenal functions. Besides, most patients with GH deficiency have multiple defficiency of pituitary hormones (both TSH and ACTH), so hGH therapy can enhances hypothyroidism and hypoadrenalism. In the Department of Pediatric Endocrinology of the Institute of Endocrinology and Metabolism a great experience was accumulated in the treatment of GH deficiency children and in the study of the efficacy and safety of this treatment.

    Spain has become the country in the European Union with the fourth highest number of overweight and obese children. This condition directly affects physical health as well as mental health. The objective of this research study was to evaluate motivational aspects in one group of obese or overweight adolescents and another group of normal-weight adolescents. For this purpose a descriptive observational study was carried out in an educational institution in Guadix (Granada). The universe was composed of 200 children of ages 10 to 14. A sample of 24 children was selected by means of proportional random sampling with an error of 0.19, and was divided into the following groups (i) 12 normal-weight children; (ii) 12 obese children. Motivation was measured by means of the School Motivation Analysis Test (SMAT), a multidimensional measuring instrument based on Cattell's dynamic model of motivation and emotions. Our study evaluated five motivational parameters: TAO (total autism-optimism), TGI (total general information), TIN (total integration), TPI (total personal interest), and TCO (total conflict). Our results showed that for each of the SMAT variables, the overweight and obese children obtained an average value of 4.5 in contrast to the normal-weight children, who obtained an average value of 5.9. This indicates that overweight and obese children have low motivational states and a higher level of frustration. They also tend to distort reality by alleging the existence of obstacles that prevent them from achieving their goals.

    Background: Childhood obesity is a world-wide health problem and development of interventions to prevent or control it is a priority. Obesity is prevalent and on the increase among school-students in Iran, too. As the first step for development of an intervention, the current study was designed to complete our understanding of ideas, attitudes, beliefs, and preferences of primary school children in Tehran, Iran. Methods: Twenty-seven primary school-students (11 boys, 16 girls) in grade-five, most of whom were overweight or obese, participated in four focus-group discussions (FGDs). All FGD notes were analyzed to find the main themes. Results: Nine themes in three main categories emerged after analysis. The themes in the category of barriers of losing weight included environmental, psychological and physiological barriers. Category of intervention components included nutrition improvement, physical activity promotion, social support and education. Setting and deliverer of the intervention were included in the intervention conditions category. The children proposed a multi-component approach for development of an intervention. They mentioned nutrition and physical activity improvement, social support and education as the main elements of an effective intervention. Conclusions: The findings indicate that obese children need to be supported against different barriers of losing weight, mainly social barriers, especially humiliation by the community.

    The incidence of childhood obesity is rising in the United Kingdom and this has far-reaching and serious consequences both for the physical and psychological well-being of the child, as well as significant financial implications for the health service. General practitioners (GPs) play a central role in identifying and assessing such children and directing them to the best services. While most cases of obesity are simply due to an imbalance in calorie intake and expenditure, children do need to be formally assessed to ensure that red flags are not missed, which might signify an important underlying aetiology, co-morbidity or complication. To date, there have not been tools available to guide a GP through this assessment. In this paper, we present and explain the thinking behind a tool, which was developed for use by GPs from Bristolas part of a trial to assess the transferability of a childhood obesity clinic into primary care. We look at the evidence base behind the guidelines and then assess the appropriateness and safety of the 152 referrals made using this tool. We believe that this screening tool would enable over 85% of obese children to seek their initial weight management in primary care. Additional evaluation is needed in different regions to ensure effectiveness, sensitivity and specificity of this new tool.

This study examined whether children with autism spectrum disorder and disruptive behavior are more likely to be overweight or obese than matched controls. Baseline data from medication-free children with autism spectrum disorder who participated in trials conducted by the Research Units on Pediatric Psychopharmacology Autism Network (N = 276) were compared to 544 control children from the National Health and Nutrition Examination Survey database matched on age, sex, race, parent education, and era of data collection. The mean age of the children with autism spectrum disorder was 7.9 ± 2.6 years; 84.4% were males. In the autism spectrum disorder group, the prevalence was 42.4% for overweight and 21.4% for obesity compared to 26.1% for overweight and 12.0% for obesity among controls (p < 0.001 for each contrast). Within the autism spectrum disorder sample, obesity was associated with minority status and lower daily living skills. These findings suggest that children with autism spectrum disorder and disruptive behavior are at increased risk for obesity and underscore the need for weight management interventions in this population.

    In is important to determine the factors that affect obesity in childhood, in order to raise generations of healthy children. This study aims to determine the effect of primary school students' eating behaviors and parental feeding styles on obesity in childhood. This descriptive cross-sectional study was conducted with 1201 children and their parents between September 2014 and March 2015. The data were collected using the socio-demographic data collection form for children and parents, the Children's Eating Behavior Questionnaire and the Parental Feeding Style Questionnaire. The data were analyzed using percentage calculators, mean, Spearman's correlation analysis, Pearson's correlation analysis and multiple regression analysis. Of the children, 16.9% were found to be obese. Three models were created considering the relationships between the variables in this study and the occurrence of obesity. In the first model, the factors that affect childhood obesity were found to be enjoyment of food, emotional overeating, food responsiveness, satiety responsiveness and food fussiness. In the second model, the factors were prompting/encouragement and control over eating. Enjoyment of food, emotional overeating, food responsiveness, satiety responsiveness, emotional feeding and food fussiness were also found to be the factors in the third model (p<0.05). This study showed that children's eating behaviors and parental feeding style affect the occurrence of obesity in childhood.

    Objective: Increasing evidence suggests that T helper (Th) cells play a significant role in the pathogenesis of hypertension. The aim of this study was to evaluate the effect of obesity and anti-hypertensive treatment on urinary Th1 chemokines. Methods: The study groups consisted of three types of patients: hypertensive obese, healthy, and non-hypertensive obese. Pre-treatment and post-treatment samples of the hypertensive obese group and one sample from the other two groups were evaluated for urinary chemokine: regulated on activation, normal T cell expressed and secreted (RANTES), interferon-gamma-inducible protein 10 (IP10), and monokine induced by interferon-gamma (MIG). In the hypertensive obese group, urine microalbumin: creatinine ratio was examined before and after treatment. We recommended lifestyle changes to all patients. Captopril was started in those who could not be controlled with lifestyle changes and those who had stage 2 hypertension. Results: Twenty-four hypertensive obese (mean age 13.1), 27 healthy (mean age 11.2) and 22 non-hypertensive obese (mean age 11.5) children were investigated. The pre-treatment urine albumin: creatinine ratio was positively correlated with pre-treatment MIG levels (r=0.41, p<0.05). RANTES was significantly higher in the pre-treatment hypertensive and non-hypertensive obese group than in the controls. The urinary IP10 and MIG levels were higher in the pre-treatment hypertensive obese group than in the non-hypertensive obese. Comparison of the pre- and post-treatment values indicated significant decreases in RANTES, IP10, and MIG levels in the hypertensive obese group (p<0.05). Conclusion: Th1 cells could be activated in obese hypertensive children before the onset of clinical indicators of target organ damage. Urinary RANTES seemed to be affected by both hypertension and obesity, and urinary IP10 and MIG seemed to be affected predominantly by hypertension. PMID:26831550

    A review of the literature on the health hazards of obesity and weight control in children indicates: 1) methodological flaws tend to invalidate the assumption that obesity is a risk factor for this age group; 2) weight control by children and adolescents may cause a variety of health problems including retardation of growth, development, mental functioning, and reproductive capacity; and 3) preoccupation with weight control in this society makes it likely that weight control-related-health problems are common phenomena. Further research into the short and long-term consequences of obesity and weight control is necessary before enlightened clinical practice in this area is possible. PMID:6336638

    Although an increasing number of children and adolescents are becoming obese, the psychological morbidities associated with obesity are not well established. Existing reviews report modest associations between obesity and global self-esteem. However, none have examined how this affects multi-component assessments of self-esteem and quality of life in young people with defined obesity. A literature search identified 17 self-esteem and 25 quality of life studies of cross-sectional, longitudinal or intervention design published since 1994. Child-completed and parent-proxy assessments were consistent in showing significant reductions in global self-esteem and quality of life in obese youth. Competences particularly affected were physical competence, appearance and social functioning. There were no clear differences in effects between children and adolescents, and evidence on gender and ethnicity was lacking. Competency improvements occurred in the presence and absence of weight loss, suggesting their value as intervention outcomes and the need for further investigation.

    Overweight and obesity is a growing problem for children in foster care. This study describes the prevalence of overweight and obesity in an urban, ethnic minority population of children ages 2-19 in long-term foster care (N = 312) in Los Angeles, California. It also investigates whether demographics or placement settings are related to high body mass index. The estimates of prevalence of overweight/obesity (≥85th percentile) and obesity (≥95th percentile) were presented for gender, age, ethnicity, and placement type. Multiple logistic regression was used to examine potential associations between demographic and placement variables and weight status. The prevalence of overweight/obesity was almost 40 % and obesity was 23 % for the study population. Children placed in a group home had the highest prevalence of overweight/obesity (60 %) and obesity (43 %) compared to other types of placement. Within this study, older children (ages 12-19) were more likely to be overweight/obese than normal weight compared to children between 2 and 5 years old when controlling for gender, ethnicity and placement (OR = 2.10, CI = 1.14-3.87). These findings suggest that older age and long-term foster care in general may be risk factors for obesity. Child welfare agencies and health care providers need to work together to train caregivers with children in long-term foster care in obesity treatment interventions and obesity prevention strategies.

    The proportion of overweight and obese children and adolescents in Germany and Europe has increased dramatically since the 1990s. About a third of obese preschool children and half of obese school children will become obese adults; the economic, medical, and psychosocial consequences are substantial. This article presents an overview of psychological risk factors and causes of obesity in children and adolescents, including comorbidity with psychological disorders, stigmatization, and relationships with peers, family, and other environment factors, as well as interactions between genes and behavior. Understanding risk factors and causes for obesity is the basis for adequate psychological interventions. We provide an overview of psychological aspects of obesity, such as motivation and impulsivity, and present components of cognitive behavioral therapy and modalities of intervention. A better understanding of psychological factors is necessary to achieve more effective interventions and long-term success of behavior change. This also holds true for changes in the social, media, and physical environment structures with the goal of promoting healthy eating and physical activity.

    Childhood overweight and obesity have an estimated prevalence of 10 % globally. High body mass index (BMI) is a known major predictor of body dissatisfaction, problem eating, low self-esteem, bullying and poor social and health outcomes for children. Childhood is also a time when lifelong habits are established, and as such is a time where prevention efforts have a high chance of success if implemented appropriately. Obesity prevention in children also has the potential to create weight, shape and food concerns in children and as such programs should focus on the principle first, do no harm. This paper canvasses existing literature and intervention program data to make the following recommendations for effective childhood obesity prevention: Programs should be educative for both children and their parents, programs should be inclusive of the whole family, there should be a focus on health and growth, not weight, and parents, schools and children should all be involved.

    Background: Epidemiologic evidences suggest a strong association between low birth weight and some diseases in adult life ( hypertension, diabetes, cardiovascular diseases).Aim of this study was to evaluate the obesity/overweight prevalence in a population of children born small for gestation age, SGA children 400, 208 males and 192 females compared to a population of children born appropriate for gestational age 6818 AGA children, 3502 males and 3316 females, during childhood. Our intention was also to build the natural history of weight gain during prepubertal age in children born SGA and AGA. Design and Methods: Observational prospective longitudinal study. We followed our patients from January2001 up to December 2010; weight, height and body mass index (BMI) were evaluated in all the SGA and AGA children. BMI z-score range for defining overweight and obesity was, respectively, 1.13 to 1.7 and >1.7 according to CDC growth charts. Results: In transversal evaluation, we prove that 10-year-old SGA females are twice obese and more overweight compared to equal age AGA females. In longitudinal evaluation, we highlight different observations: SGA children obese at 2 years are still obese at 10 years; the number of obese SGA children increases gradually until the age of 10; AGA children, appear to be less obese than SGA children at 10 years. Conclusion: SGA males and females are more obese at 5 and 10 years compared to the AGA population. Primary care pediatricians, through early detection of the children at risk, can carry out an effective obesity prevention project in SGA children. PMID:27583297

    Background Obesity ignites numerous health and psychosocial problems and is associated with various comorbidities. Body mass index (BMI) is also independently associated with improved risk for numerous kidney disorders. As renal length is considered a vital parameter in the clinical assessment of renal patients, normal renal length has to be defined in accordance to BMI. Objectives The aim of this study was to define normal kidney length in obese children, comparing ultrasound measurements of the kidney length in obese and non-obese children and adolescents, in order to reduce unnecessary evaluations for nephromegaly. Patients and Methods Fifty obese children and adolescents and 50 non-obese children and adolescents, aged 1-19 years, were selected from patients of pediatric clinics in two hospitals (Rasoul-e-Akram and Shahid Fahmideh) in Tehran between June 2010 and 2012. After the nephrologist’s and endocrinologist’s approval, the largest longitudinal renal dimension was measured in deep inspiration position by abdomino-pelvic ultrasonography in both groups. Results It was revealed that both kidneys in obese group were significantly larger than in control group (P = 0.044 and 0.040, respectively). Obesity status, height and age were proven to be significant and independent predictors of length of both kidneys. In both groups length of left kidney was significantly larger than that of right kidney (P < 0.001). Conclusions A specific standard cut-point limit or norm gram has to be formulated for obese children and adolescents in order to facilitate the diagnosis of kidney diseases, including organomegaly, in these patients.

    Fat accumulation leads to dysfunction of hypothalamic-pituitary-thyroid axis and to changes in thyroid function. A higher serum level of thyroid stimulating hormone (TSH), with normal levels of thyroid hormones, suggesting subclinical hypothyroidism, is often found in obese individuals. The influence on lipid and glucose metabolism of thyroid dysfunction in obese patients remains unclear. This retrospective study encompassed 110 obese children and 38 healthy non-obese children aged 5-18. Anthropometric measurements, including bioelectrical impedance, were taken in all children. Fasting TSH, fT4, glucose, lipid profile, and a glucose tolerance test in case of the obese individuals, were evaluated. The obese children demonstrated a significantly higher mean concentration of TSH compared with their peers with proper body weight: 2.1 ± 1.0 μIU/ml vs. 1.5 ± 0.6 μIU/ml, p = 0.001. The fT4 was not different between the two groups. In the obese children, TSH correlated with body mass index (BMI) and waist circumference after controlling for age and gender. A multivariate regression analysis showed a relationship of TSH with total cholesterol, LDL cholesterol, triglycerides, and non-HDL after adjusting for BMI. None of these relationships were revealed for fT4. The level of TSH correlated with the degree of abdominal obesity. We conclude that the serum TSH concentration, even remaining within the norm, could adversely affect the lipid profile, irrespective of obesity.

    Obesity and headaches are common in children and adults. Adult studies suggest obesity is a risk factor for chronic daily headache and increased migraine frequency and severity. Pediatric studies have suggested a relationship between obesity, increasing headache frequency, and disability. The authors retrospectively evaluated 925 children from their Pediatric Headache Clinic between July 2004 and July 2008, assessing headache frequency, medication overuse, and body mass index compared to population-based norms. The pediatric headache group as a whole had a greater percentage of overweight than the general population. This was also true with the subgroup of patients with chronic tension-type headache, although the numbers were small. Data did not show increased incidence of overweight in children with medication overuse or chronic migraine. This contrasts with adult data, which have suggested a closer link between chronic migraine and obesity and have not supported a link with chronic tension-type headache.

    Background The mechanisms and consequences of the observed association between obesity and childhood asthma are unclear. Objectives To determine the effect of obesity on treatment responses to inhaled corticosteroids in asthmatic children. Methods We performed a post hoc analysis to evaluate the interaction between body mass index (BMI) and treatment with inhaled budesonide on lung function in the Childhood Asthma Management Program (CAMP) trial. Participants were then stratified into overweight/obese and non-overweight, and their response to inhaled budesonide was analyzed longitudinally over the 4 years of the trial. Results There was a significant interaction between BMI and budesonide for pre-BD FEV1/FVC (P=0.0007) and bronchodilator response (BDR) (P=0.049), and a non-significant trend for an interaction between BMI and budesonide on pre-BD FEV1 (P=0.15). Non-overweight children showed significant improvement with inhaled budesonide in lung function (FEV1, FEV1/FVC, and BDR) during the early (years 1–2) and late stages (years 3–4) of the trial. Overweight/obese children had improved FEV1 and BDR during the early but not the late stage of the trial, and showed no improvement in FEV1/FVC. When comparing time points where both groups showed significant response, the degree of improvement among non-overweight children was significantly greater than in overweight/obese children at most visits. Non-overweight children had a 44% reduction in the risk of ER visits or hospitalizations throughout the trial (P=0.001); there was no reduction in risk among overweight/obese (P=0.97). Conclusions Compared to children of normal weight, overweight/obese children in CAMP showed a decreased response to inhaled budesonide on measures of lung function and ER visits/hospitalizations for asthma.

    Background Obesity affects lung function and respiratory muscle strength. The aim of the present study was to assess lung function and respiratory muscle strength in children with obesity and determine the influence of body composition on these variables. Methods A cross-sectional study was conducted involving 75 children (40 with obesity and 35 within the ideal weight range) aged 6 - 10 years. Body mass index, z score, waist circumference, body composition (tetrapolar bioimpedance), respiratory muscle strength and lung function (spirometry) were evaluated. Results Children with obesity exhibited larger quantities of both lean and fat mass in comparison to those in the ideal weight range. No significant differences were found between groups regarding the respective reference values for respiratory muscle strength. Male children with obesity demonstrated significantly lower lung function values (forced expiratory volume in the first second % (FEV1%) and FEV1/forced vital capacity % (FVC%) : 93.76 ± 9.78 and 92.29 ± 3.8, respectively) in comparison to males in the ideal weight range (99.87 ± 9.72 and 96.31 ± 4.82, respectively). The regression models demonstrated that the spirometric variables were influenced by all body composition variables. Conclusion Children with obesity demonstrated a reduction in lung volume and capacity. Thus, anthropometric and body composition characteristics may be predictive factors for altered lung function.

    The present study was conducted to examine whether prepubertal-onset exercise might help adults maintain long-term body weight (BW) reduction and increased energy metabolism after the cessation of exercise. Furthermore, the effects of the exercise regimen were compared with those of food restriction. Twenty-three male obese-diabetic [Otsuka Long-Evans Tokushima Fatty (OLETF)] rats were randomly assigned to prepubertal-onset exercise (Childhood-Ex), food restriction (Childhood-Diet), and sedentary control (OLETF-Sed) groups. Childhood-Ex rats exercised voluntarily every day using a rotating wheel, while the food volume of the Childhood-Diet group was restricted to achieve a BW similar to that recorded in the Childhood-Ex group. Both treatments were conducted at 5-19 wk of age; after this period, the rats were kept sedentary and allowed ad libitum food intake until 45 wk of age. BW was significantly lower, and percent lean body mass was significantly higher, in the Childhood-Ex group compared with those in the Childhood-Diet and OLETF-Sed groups throughout maturation and middle age after cessation of the interventions. The Childhood-Ex group also demonstrated higher citrate synthase, succinate dehydrogenase, and phosphofructokinase activity levels, as well as uncoupling protein-3 mRNA expression in skeletal muscle. This study revealed that inhibited BW gain in an animal model of human obese diabetes by prepubertal-onset exercise lasted for a long period after the completion of the exercise intervention. This effect may be facilitated by increased energy metabolism. However, these benefits were not found by prepubertal food restriction treatment. Importantly, to allow translation of our work, these novel insights need to be assessed in obese human individuals.

    Evidence from our previous study suggested that the incidence of germ cell neoplasms in children and adolescents is increasing. The objectives of this analysis were to quantify this trend in patients aged 0-9 and 10-19 years (pre-pubertal and adolescent groups, respectively) and compare rates in Taiwan according to geographic distribution. Germ cell neoplasm frequencies among 1267 patients aged 0-19 years spanning 1995-2009 were obtained from the population-based Taiwan Cancer Registry. The incidence patterns according to sex, age, disease subgroup, and geographic distribution were analyzed. The incidence rates in the pre-pubertal and adolescent groups were 10.58 and 16.06 per million person-years, respectively. The overall rates increased significantly by 3.2% annually in the adolescent group during the 15-year study period, and increased only among the males. In contrast, no change in trend was observed in the pre-pubertal group. Subgroup analysis showed significant upward trends in the incidence rates of intracranial/intraspinal and testicular germ cell tumors (GCTs) in the adolescent males and extracranial/extragonadal GCTs in the pre-pubertal boys. The most striking differences between the study population and white Americans were that the rates of testicular GCTs were 5-fold higher and 4-fold lower in the Taiwanese pre-pubertal and adolescent groups, respectively. Significantly higher rates were found in Hualien and Chiayi Counties compared with the other areas of Taiwan. The upward trend of testicular GCTs in the adolescent males is consistent with findings from Western countries. The underlying causes that led to the high rate of testicular GCTs in the pre-pubertal boys and significantly higher rates in specific counties warrant further investigation.

    SUMMARY BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in children. Liver disease can be a cause of low bone mineral density. Whether NAFLD influences bone health is unknown. AIM To evaluate bone mineral density in obese children with and without NAFLD. METHODS Thirty-eight children with biopsy-proven NAFLD were matched for age, sex, race, ethnicity, height, and weight to children without evidence of liver disease from the National Health and Nutrition Examination Survey. Bone mineral density was measured by dual energy x-ray absorptiometry. Age and sex-specific bone mineral density Z-scores were calculated and compared between children with and without NAFLD. After controlling for age, sex, race, ethnicity, and total percent body fat, the relationship between bone mineral density and the severity of histology was analyzed in children with NAFLD. RESULTS Obese children with NAFLD had significantly (p<0.0001) lower bone mineral density Z-scores (−1.98) than obese children without NAFLD (0.48). Forty-five percent of children with NAFLD had low bone mineral density for age, compared to none of the children without NAFLD (p < 0.0001). Among those children with NAFLD, children with NASH had a significantly (p< 0.05) lower bone mineral density Z-score (−2.37) than children with NAFLD who did not have NASH (−1.58). CONCLUSIONS NAFLD was associated with poor bone health in obese children. More severe disease was associated with lower bone mineralization. Further studies are needed to evaluate the underlying mechanisms and consequences of poor bone mineralization in children with NAFLD. PMID:22111971

    Ob­jec­ti­ve: We aimed to determine the association of thyroid functions with the components of metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD) in pediatric obese patients. Methods: The study included 109 obese children (aged 9-15 years) and a control group of 44 healthy age and gender-matched children of normal weight. NAFLD was diagnosed by conventional ultrasound examination. We assessed the anthropometric data and serum biochemical parameters including lipid profile, alanine aminotransferase (ALT), fasting glucose and insulin levels and thyroid stimulating hormone (TSH), free thyroxine (fT4) and free triiodothyronine (fT3) levels. The homeostasis model assessment of insulin resistance (HOMA-IR) was calculated as a measure of IR. Results: The mean age and gender distributions in the groups were similar (p=0.23). The mean body mass index (BMI) z-scores of obese children with grade 2-3 NAFLD were significantly higher than those of the obese children without hepatic steatosis (p<0.001). Mean ALT, triglyceride (TG) and LDL cholesterol increased and HDL-cholesterol significantly decreased as the hepatic steatosis increased (p<0.05). HOMA-IR levels in obese subjects with grade 2-3 NAFLD were significantly higher than those in both obese children without NAFLD and grade 1 NADFL (p=0.05 and 0.001, respectively). In the obese subjects, TSH levels were increased significantly as the degree of steatosis increased (p=0.04) but fT3 and fT4 levels were not different. In correlation analysis, TSH was significantly correlated with ALT, BMI SDS and the degree of steatosis. Conclusions: Obese children demonstrate an increase in TSH levels as the degree of steatosis increased. PMID:24637308

    Obese adult patients have many dermatoses, such as skin tags, candida infection, cellulite, and intertrigo, but only limited data have been published on obese children and the barrier function of their skin. Sixty-five overweight and obese children (n = 40, BMI 85th-95th percentile; n = 25, BMI > 95th percentile) (aged 8-15; mean age 11.6) and 30 normal-weight controls (aged 7-15; mean age 11.1) underwent a clinical evaluation and calculation of transepidermal water loss (TEWL). Higher weight percentile was associated with a higher incidence of some dermatoses. Skin tags were found in 40% of subjects in the 95th percentile and 2.5% of those in the 85th percentile. Striae distensae were observed in 32% of patients in the 95th percentile and 22.5% of those in the 85th percentile. Plantar hyperkeratosis was observed only in 20% of the 95th percentile subjects and was not observed in the other groups. TEWL values at the forearm site were significantly higher (p < 0.05) in obese children than in the control group, but no significant differences in TEWL values according to BMI level were found between the two groups of obese children. Degree of obesity influences the incidence of some associated dermatoses; skin tags, striae distensae, and plantar hyperkeratosis were more frequent in children in the 95th percentile of BMI. Obesity increases the TEWL rate, suggesting that obese children might become more easily overheated as weight increases, with more profuse sweating because of the thick layers of subcutaneous fat.

    Background: Obesity has become a serious problem for Chinese Han nationality. This research aimed to evaluate the prevalence of and trends in obesity among Chinese Korean nationality children and adolescents (1991–2010). Methods: We used data from Chinese National Surveys on Students’ Constitution and Health (CNSSCH). CNSSCH was utilized to monitor Chinese students’ health condition and released its data every 5 yr (1991, 1995, 2000, 2005 and 2010). The standard weight-for-height was the 80th percentile for sex- and age-specific growth charts based on the 1985 CNSSCH data. Obesity was defined as ≧120% of standard weight-for-height. Results: The total age-adjusted prevalence of obesity was 15.9% (95% confidence interval (CI), 14.9–16.9%) among Chinese Korean children and adolescents aged 7 to 18 yr. Children or adolescents who were boys (Rate ratios (RR), 1.35; 95% CI, 1.19–1.53) or aged 10–12 (RR, 1.38; 95% CI, 1.17–1.63) were more likely to be obese. The trend analysis of the 19-yr period implied a serious annual increasing trend during 1991–2000 (RR, 1.05; 95% CI, 1.02–1.07) and during 2000–2010 (RR,, 1.12; 95% CI, 1.11–1.13). Chinese Korean children may also be more likely to become obese than Han nationality children during 1991–2010. Conclusion: A serious and continuous increasing trend was in the prevalence of obesity among Chinese Korean children and adolescents during 1991–2010. Childhood obesity had become a serious problem. This prognosis is worrisome. PMID:27648414

    The present study was performed to determine the prevalence of metabolic syndrome (MS) and its risk factors in obese children and adolescents. The study included 352 obese children and adolescents (body mass index [BMI] > or = 95th percentile) aged between 2 and 19 years. The diagnosis of MS was made according to the criteria adapted from the World Health Organization (WHO) and the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines. BMI z-scores were calculated to assess the degree of obesity. The prevalence of MS and risk factors were determined. Determinants of MS were examined using regression analysis. The prevalence of MS was 41.8%. The age at onset of obesity, sedentary life-span, fasting blood levels of glucose, insulin, triglyceride, very-low-density lipoprotein (VLDL) cholesterol, and alanine aminotransferase (ALT) were higher, while levels of high-density lipoprotein (HDL) cholesterol and the number of actively spent hours were lower in cases with MS (p < 0.05). The most important determinant of MS was BMI z-score (r = 0.31, p < 0.0001). A one-point increase in BMI z-score yielded a 2-fold increase in the prevalence of MS. The prevalence of MS increased from 27.6% to 60.7% when the BMI z-score increased from 2.3 to 3.3. The risk of developing MS was 2.6-fold higher in cases with BMI z-score > 3 when compared to those with z-scores between 2 and 3. The results from this study indicate that, although the correlation between MS and the BMI z-score was weak, the BMI z-score may be an effective parameter in identifying obese children and adolescents at risk for MS. Screening the cases with BMI z-scores > or = 2 for MS is important for establishing an early diagnosis.

    Previous research has suggested that perceptual-motor difficulties may account for obese children's lower motor competence; however, specific evidence is currently lacking. Therefore, this study examined the effect of altered visual conditions on spatiotemporal and kinematic gait parameters in obese versus normal-weight children. Thirty-two obese and normal-weight children (11.2±1.5 years) walked barefoot on an instrumented walkway at constant self-selected speed during LIGHT and DARK conditions. Three-dimensional motion analysis was performed to calculate spatiotemporal parameters, as well as sagittal trunk segment and lower extremity joint angles at heel-strike and toe-off. Self-selected speed did not significantly differ between groups. In the DARK condition, all participants walked at a significantly slower speed, decreased stride length, and increased stride width. Without normal vision, obese children had a more pronounced increase in relative double support time compared to the normal-weight group, resulting in a significantly greater percentage of the gait cycle spent in stance. Walking in the DARK, both groups showed greater forward tilt of the trunk and restricted hip movement. All participants had increased knee flexion at heel-strike, as well as decreased knee extension and ankle plantarflexion at toe-off in the DARK condition. The removal of normal vision affected obese children's temporal gait pattern to a larger extent than that of normal-weight peers. Results suggest an increased dependency on vision in obese children to control locomotion. Next to the mechanical problem of moving excess mass, a different coupling between perception and action appears to be governing obese children's motor coordination and control.

    Objectives. Modifiable behaviors during the first 1000 days (conception age 24 months) mediate Hispanic children's obesity disparities. We aimed to examine underlying reasons for early life obesity risk factors and identify potential early life intervention strategies. Methods. We conducted 7 focus groups with 49 Hispanic women who were pregnant or had children < age 24 months. Domains included influences on childhood obesity risk factors and future intervention ideas. We analyzed data with immersion-crystallization methods until no new themes emerged. Results. Themes included coping with pregnancy may trump healthy eating and physical activity; early life weight gain is unrelated to later life obesity; fear of infant hunger drives bottle and early solids introduction; beliefs about infant taste promote early solids and sugary beverage introduction; and belief that screen time promotes infant development. Mothers identified physicians, nutritionists, and relatives as important health information sources and expressed interest in mobile technology and group or home visits for interventions. Conclusion. Opportunities exist in the first 1000 days to improve Hispanic mothers' understanding of the role of early life weight gain in childhood obesity and other obesity risk factors. Interventions that link health care and public health systems and include extended family may prevent obesity among Hispanic children. PMID:25874127

    Objective: Urinary netrin-1 is a new marker to demonstrate early tubular damage. The aim of this study was to determine whether urinary netrin-1 is increased in obese children. Methods: A total of 68 normoalbuminuric and normotensive obese patients and 65 controls were included in the study. Urine samples were collected for assessment of urinary phosphorus, sodium, potassium, creatinine, albumin, and netrin-1. Blood samples were collected for measurements of fasting glucose, insulin, lipid, phosphorus, sodium, potassium, and creatinine levels. Homeostatic model assessment insulin resistance index was calculated. Results: Gender and age were similar between obese and control groups (12.01±3.03 vs. 11.7±3.2 years, p=0.568 and 33 vs. 35 girls, p=0.543, respectively). Obese patients had significantly higher netrin-1 excretion than the controls (841.68±673.17 vs. 228.94±137.25 pg/mg creatinine, p=0.000). Urinary netrin-1 level was significantly higher in obese subjects with insulin resistance compared to those without insulin resistance (1142±1181 vs. 604.9±589.91 pg/mg creatinine, p=0.001). Conclusion: In normotensive and normoalbuminuric obese children, urinary netrin-1 level can increase before onset of albuminuria. Urinary netrin-1 excretion appears to be affected predominantly by insulin resistance and hyperinsulinemia. Urinary netrin-1 may be a new biomarker for determining early tubular injury in obese children. PMID:27087488

    Obesity disproportionately affects U.S. ethnic minority preschool children, placing them at risk for obesity related co-morbidities and premature death. Effective culturally appropriate interventions are needed to improve health behaviors and reduce obesity in young high-risk minority children, while their behaviors are still developing. All known obesity intervention studies (e.g., diet and physical activity) since 2000 targeting U.S. ethnic minority preschool children were reviewed. Five electronic databases and eight published literature reviews were used to identify the studies. Intervention studies without identified ethnic minority participants were excluded. Ten obesity interventions studies met the review criteria. Published cultural adaptation guidelines were used to develop a mechanism to analyze, score, and rank the intervention adaptations. Cultural adaptations varied widely in rigor, depth, and breadth. Results indicated a relative absence of appropriately adapted obesity interventions for ethnic minority groups, suggesting a need for more rigorous cultural adaptation guidelines when designing obesity interventions for diverse ethnicities. Culturally appropriate adaptations appeared to enhance intervention relevance, effectiveness, and feasibility. The purpose of this literature review was to evaluate 1) the type and extent of cultural adaptations strategies applied to the interventions, and 2) how these adaptations related to the study outcomes.

    Objective: To investigate the association between serum uric acid levels and insulin resistance in children and adolescents with obesity. Methods: Cross-sectional study with 245 children and adolescents (134 obese and 111 controls), aged 8-18 years. The anthropometric variables (weight, height and waist circumference), blood pressure and biochemical parameters were collected. The clinical characteristics of the groups were analyzed by t-test or chi-square test. To evaluate the association between uric acid levels and insulin resistance the Pearson's test and logistic regression were applied. Results: The prevalence of insulin resistance was 26.9%. The anthropometric variables, systolic and diastolic blood pressure and biochemical variables were significantly higher in the obese group (p<0.001), except for the high-density-lipoprotein cholesterol. There was a positive and significant correlation between anthropometric variables and uric acid with HOMA-IR in the obese and in the control groups, which was higher in the obese group and in the total sample. The logistic regression model that included age, gender and obesity, showed an odds ratio of uric acid as a variable associated with insulin resistance of 1.91 (95%CI 1.40-2.62; p<−0.001). Conclusions: The increase in serum uric acid showed a positive statistical correlation with insulin resistance and it is associated with and increased risk of insulin resistance in obese children and adolescents.

    Background Mexico is a developing country with one of the highest youth obesity rates worldwide; >34% of children and adolescents between 5 and 19 years of age are overweight or obese. Objectives The current review seeks to compile, describe, and analyze dietary conditions, physical activity, socioeconomic status, and cultural factors that create and exacerbate an obesogenic environment among Mexican youth. Design A narrative review was performed using PubMed and the Cochrane Library databases, as well as grey literature data from the Mexican government, academics, and statistical reports from nongovernmental organizations, included in electronic formats. Results The recent socioeconomic and nutritional transition has resulted in reduced healthy meal options at public schools, high rates of sedentary lifestyles among adolescents, lack of open spaces and playgrounds, socioeconomic deprivation, false or misunderstood sociocultural traditional beliefs, misconceptions about health, a high percentage of overweight or obese adults, and low rates of maternal breastfeeding. Some of the factors identified are exacerbating the obesity problem in this population. Current evidence also shows that more policies and health programs are needed for prevention of childhood and adolescent obesity. Mexico presents alarming obesity levels, which need to be curtailed and urgently reversed. Conclusions The present narrative review presents an overview of dietary, physical activity, societal and cultural preconceptions that are potentially modifiable obesity-promoting factors in Mexican youth. Measures to control these factors need to be implemented in all similar developing countries by governments, policy makers, stakeholders, and health care professionals to tackle obesity in children and young people.

    2016-10-01

    Obesity is a growing public health concern and is more prevalent among low-income and minority populations. Food insecurity may increase the odds of obesity in children. We investigated the association between food insecurity and obesity among low-income, Hispanic, mother-child dyads (n = 74). The United States Department of Agriculture 18-item Household Food Security Survey was used to determine food security status. The majority of households were food insecure (74 %) and one-third (30 %) of children were obese. Food insecurity increased the odds of childhood obesity (OR 10.2; 95 % CI 1.2, 85.5) with stronger associations found within households where mothers were also overweight/obese compared to normal weight (p-for interaction < 0.05). Rates of household food insecurity and childhood obesity were high among this low-income Hispanic sample. Future studies should elucidate the mechanisms through which food insecurity impacts childhood obesity.

    BACKGROUND: Obesity is associated with poor asthma control, increased asthma morbidity, and decreased response to inhaled corticosteroids. We hypothesized that obesity would be associated with decreased bronchodilator responsiveness in children and adolescents with asthma. In addition, we hypothesized that subjects who were obese and unresponsive to bronchodilator would have worse asthma control and would require more asthma controller medications. METHODS: In the Study of African Americans, Asthma, Genes, and Environments (SAGE II) and the Genes-environments and Admixture in Latino Americans (GALA II) study, two identical, parallel, case-control studies of asthma, we examined the association between obesity and bronchodilator response in 2,963 black and Latino subjects enrolled from 2008 to 2013 using multivariable logistic regression. Using bronchodilator responsiveness, we compared asthma symptoms, controller medication usage, and asthma exacerbations between nonobese (< 95th% BMI) and obese (≥ 95th% BMI) subjects. RESULTS: The odds of being bronchodilator unresponsive were 24% (OR, 1.24; 95% CI, 1.03-1.49) higher among obese children and adolescents compared with their not obese counterparts after adjustment for age, race/ethnicity, sex, recruitment site, baseline lung function (FEV1/FVC), and controller medication. Bronchodilator-unresponsive obese subjects were more likely to report wheezing (OR, 1.38; 95% CI, 1.13-1.70), being awakened at night (OR, 1.34; 95% CI, 1.09-1.65), using leukotriene receptor inhibitors (OR, 1.33; 95% CI, 1.05-1.70), and using inhaled corticosteroid with long-acting β2-agonist (OR, 1.37; 95% CI, 1.05-1.78) than were their nonobese counterpart. These associations were not seen in the bronchodilator-responsive group. CONCLUSIONS: Obesity is associated with bronchodilator unresponsiveness among black and Latino children and adolescents with asthma. The findings on obesity and bronchodilator unresponsiveness represent a unique

    Obesity, dental caries and periodontal diseases are among major public health concerns which may affect children's growth and development. This study seeks any clustering between obesity, oral health and life-style factors among school children in Istanbul, Turkey. A cross-sectional study of children, 10- to 12-year-olds, from a public and a private school was undertaken with questionnaires for children and their mothers and child oral health data, in Istanbul (n = 611). DMFS (number of decayed, missing and filled surfaces of permanent teeth), CPI (Community Periodontal Index), body mass index (BMI) and life-style factors (tooth-brushing frequency, milk consumption at breakfast and bedtimes on school nights) of children were examined. Data analysis included factor analysis, Student's t test and Chi-square tests by cross-tabulation. Public school children were more dentally diseased but less obese than were those in private school (P < 0.001). They more frequently had calculus (62%) and reported non-recommended tooth-brushing (68%) than did those in private school (37%, 56%; P < 0.05). Principal component analysis revealed that DMFS, CPI and BMI shared the same cluster among all children. A need exists for addressing obesity, oral health and nutrition jointly in health promotion strategies to improve children's well-being and empower good life-style factors.

    Obesity may be a risk factor for increased hospitalization and deaths from infections due to respiratory pathogens. Additionally, obese patients appear to have impaired immunity after some vaccinations. To evaluate the immunogenicity, safety and tolerability of an inactivated trivalent influenza vaccine (TIV) in overweight and obese children, 28 overweight/obese pediatric patients and 23 healthy normal weight controls aged 3-14 years received a dose of TIV. Four weeks after vaccine administration, significantly higher seroprotection rates against the A/H1N1 strain were observed among overweight/obese children compared with normal weight controls (p<0.05). Four months after vaccination, similar or slightly higher seroconversion and seroprotection rates against the A/H1N1 and A/H3N2 strains were detected in overweight/obese than in normal weight children, whereas significantly higher rates of seroconversion and seroprotection against the B strain were found in overweight/obese patients than in normal weight controls (p<0.05 for seroconversion and seroprotection). Geometric mean titers (GMTs) and fold increase against B strains were significantly higher in overweight/obese patients than in normal weight controls 4 months after vaccine administration (p<0.01 for GMT values and p<0.05 for fold increase). The frequency of local and systemic reactions was similar between the groups, and there were no serious adverse events. The results of this study indicate that in overweight and obese children, antibody response to TIV administration is similar or slightly higher than that evidenced in normal weight subjects of similar age and this situation persists for at least 4 months after vaccine administration in the presence of a favorable safety profile.

    This study tested whether children’s eating behavior and parental feeding prompts during a laboratory test meal differ among children born at high risk (HR) or low risk (LR) for obesity and are associated with excess child weight gain. At 4 years of age, 32 HR children (mean maternal prepregnancy BMI = 30.4 kg/m2) and 29 LR children (maternal BMI = 19.6 kg/m2) consumed a test meal in which their eating behavior was assessed, including rate of caloric consumption, mouthfuls/min, and requests for food. Parental prompts for the child to eat also were measured at year 4, and child body composition was measured at ages 4 and 6 years. T-tests, and logistic and multiple regression analyses tested study aims. Results indicated that HR and LR children did not differ in eating rate or parental feeding prompts. Greater maternal BMI, child mouthfuls of food/min, and total caloric intake/min during the test meal predicted an increased risk of being overweight or obese at age 6, whereas greater active mealtime was associated with a reduced risk of being overweight or obese. Regression analyses indicated that only mouthfuls of food/min predicted changes in BMI from 4 to 6 years, and mouthfuls of food/min and gender predicted 2-year changes in sum of skinfolds and total body fat. Thus, a rapid eating style, characterized by increased mouthfuls of food/min, may be a behavioral marker for the development of childhood obesity. PMID:19779474

  7. Clustering of attitudes towards obesity: a mixed methods study of Australian parents and children

    PubMed Central

    2013-01-01

    Background Current population-based anti-obesity campaigns often target individuals based on either weight or socio-demographic characteristics, and give a ‘mass’ message about personal responsibility. There is a recognition that attempts to influence attitudes and opinions may be more effective if they resonate with the beliefs that different groups have about the causes of, and solutions for, obesity. Limited research has explored how attitudinal factors may inform the development of both upstream and downstream social marketing initiatives. Methods Computer-assisted face-to-face interviews were conducted with 159 parents and 184 of their children (aged 9–18 years old) in two Australian states. A mixed methods approach was used to assess attitudes towards obesity, and elucidate why different groups held various attitudes towards obesity. Participants were quantitatively assessed on eight dimensions relating to the severity and extent, causes and responsibility, possible remedies, and messaging strategies. Cluster analysis was used to determine attitudinal clusters. Participants were also able to qualify each answer. Qualitative responses were analysed both within and across attitudinal clusters using a constant comparative method. Results Three clusters were identified. Concerned Internalisers (27% of the sample) judged that obesity was a serious health problem, that Australia had among the highest levels of obesity in the world and that prevalence was rapidly increasing. They situated the causes and remedies for the obesity crisis in individual choices. Concerned Externalisers (38% of the sample) held similar views about the severity and extent of the obesity crisis. However, they saw responsibility and remedies as a societal rather than an individual issue. The final cluster, the Moderates, which contained significantly more children and males, believed that obesity was not such an important public health issue, and judged the extent of obesity to be

    2009-02-01

    Fragile Families and Wellbeing Study (FFS) data were analyzed to examine the relationships between obesity, household instability, and area poverty in urban mothers and their children (N=1,449). The FFS was conducted in 20 U.S. cities between 2001 and 2004. Household instability was defined as a tenuous home environment where certain psychosocial and economic constraints are present. Area poverty was determined according to the 2000 U.S. Census. Relative weight increased with level of household instability in mothers but not in children. Mothers with the highest level of household instability within areas of low poverty (i.e., relatively little poverty) were more likely than others to be obese (Odds Ratio=1.8, 95% CI 1.2-2.6). Household instability was not associated with overweight in children. These results suggest that home stability should be considered as a possible risk factor for obesity in mothers with infant children, particularly those residing in low poverty areas.

    2012-01-01

    Objectives: The aim of the study was to compare the prevalence of vitamin D deficiency in obese and non-overweight children in North Texas, to examine relationships between dietary habits and 25-hydroxyvitamin D [25(OH)D] level in obese children, and to examine the relationship between 25(OH)D level and markers of abnormal glucose metabolism and blood pressure. Patients and Methods: Using a cross-sectional design, systolic and diastolic blood pressure, dietary information, serum 25(OH)D, fasting glucose and insulin, 2-h glucose from oral glucose tolerance test, hemoglobin A1c, and homeostasis model assessment of insulin resistance were recorded for 411 obese subjects (6–16 yr old) at an obesity referral clinic. 25(OH)D was also obtained from 87 control non-overweight subjects (6–16 yr old). Results: Ninety-two percent of obese subjects had a 25(OH)D level below 75 nmol/liter, and 50% were below 50 nmol/liter. Among non-overweight subjects, these frequencies were 68 and 22%, respectively (both P < 0.01 compared with obese subjects). 25(OH)D was negatively associated with soda intake (P < 0.001), juice intake (P = 0.009), and skipping breakfast (P < 0.001). 25(OH)D was negatively correlated with homeostasis model assessment of insulin resistance (r = −0.19; P = 0.001) and 2-h glucose (r = −0.12; P = 0.04) after adjustment for body mass index and age but was not correlated with hemoglobin A1c, systolic blood pressure Z score, or diastolic blood pressure Z score. Conclusions: Vitamin D deficiency is common in children in this southern United States location and is significantly more prevalent in obese children.

    Abstract Background No studies have been reported on children obesity prevalence of Guangzhou, one of the most urbanized areas in China. This study tracks the secular trends of obesity prevalence of children. Methods The data were derived from the surveys on students’ constitution and health carried out by government. Randomly, 3832 students in 2007, 13141 in 2008, 14052 in 2009, 13750 in 2010, and 15225 in 2011, aged 7-12 years, from urban primary school were examined. Anthropometric parameters were measured in all students. Results The mean of body mass index increased significantly from 16.6 in 2008 to 16.8 in 2011 in the total group of children, and the total prevalence of overweight and obesity increased from 9.4 and 6.2 to 10.5 and 7.5 from 2007 to 2011, respectively. The minimum value of the mean body mass index and the overweight and obesity prevalence in the total age group all appeared in 2008. The prevalence of overweight and obesity in males was significantly higher than that in females in each year among the 5 years. Conclusion Although the prevalence of children obesity in Guangzhou in 2011 is still lower than the average values of Chinese large coastal cities, a significant increase was found in their prevalence from 2007 to 2011 and the total obesity prevalence of children is even higher than that of adolescent. Furthermore, we found that the minimum value of overweight and obesity prevalence of the total group and almost all gender-specific age groups appeared in 2008. PMID:26060774

    Background: Physical activity is important for prevention of overweight and obesity in growing children. Objective: The present study aims to explore the association of overweight and obesity in school children of the district of Dehradun with physical activity, sports, and recreation at home and school. Materials and Methods: A cross-sectional survey of 1266 schoolchildren of select private and government schools in urban and rural areas was done. Results: Overall 15.6% of children were overweight, of which 5.4% were obese. Overweight and obesity were significantly associated with physical inactivity related to passive transport to school, missed opportunities for play during lunch breaks, lack of participation in household work, and excessive viewing of television. Conclusion: We found a significant association between the lack of physical activity and overweight and obesity. There is a need to enhance physical activity, sports, and recreational opportunities at school as well as home to prevent overweight and obesity in children. Family physicians should include counseling for this important and cheap modifiable risk factor in their family care practice. PMID:28217584

    Obesity is undoubtedly one of the biggest medical problems of the 21st century. Regrettably, the problem affects more and more children and adolescents. 10% of world's school-aged children have an excess body weight and a quarter of these children are obese. In Europe every fifth school-aged child suffers from an excess body weight. The prevalence of overweight and obesity among Polish adolescents is about 14%. An excess body weight can be the consequence of genetic factors, endocrine disorders or certain drugs. However, "simple obesity" is the most common, consequence of providing too much energy from food products in comparison to energy expenditure (caloric excess). Today's lifestyle promotes the development of obesity. The lack of physical activity, sedentary lifestyle and energy-rich diet are the main causes of an excess body fat accumulation. Because of improper eating behaviours children consume an excess amount of energy; and their diet is deficient in elements necessary for proper development. The examples of such bad eating habits are: snacking highly processed and calorie-rich foods between meals eating in front of the TV screen, skipping breakfasts, drinking sugar-sweetened beverages, "eating out" frequently and "emotional eating". Bad eating behaviours are crucial factors for the development of obesity. Eating habits are usually formed in early childhood and parents play a very important role in their development.

    Obstructive sleep apnoea (OSA) has been inconsistently associated with insulin resistance and adverse metabolic states. We aimed to assess independent contributions of OSA to insulin resistance and dyslipidaemia in a large paediatric cohort.Habitually snoring children underwent overnight polysomnography, anthropometric measurements and fasting laboratory evaluations. Primary outcome measures included insulin, glucose, homeostasis model of insulin resistance, lipoproteins and sleep disturbance measures.Among 459 children aged 5-12 years, obesity was the primary driver of most associations between OSA and metabolic measures, but sleep duration was inversely associated with glucose levels, with N3 and rapid eye movement (REM) sleep being negatively associated and sleep fragmentation positively associated with insulin resistance measures. In children with mild OSA, the presence of obesity increased the odds for insulin resistance, while higher apnoea/hypopnoea index values emerged among obese children who were more insulin-resistant.The exclusive presence of interactions between OSA and obesity in the degree of insulin resistance is coupled with synergistic contributions by sleep fragmentation to insulin resistance in the context of obesity. Insufficient N3 or REM sleep may also contribute to higher glycaemia independently of obesity. Studies are needed to better delineate the roles of puberty and sleep fragmentation in insulin resistance and the metabolic syndrome.

    Background: Elevated aminotransferases serve as surrogate markers of non-alcoholic fatty liver disease, a feature commonly associated with the metabolic syndrome. Studies on the prevalence of fatty liver disease in obese children comprise small patient samples or focus on those patients with liver enzyme elevation. Objectives: We have prospectively analyzed liver enzymes in all overweight and obese children coming to our tertiary care centre. Patients and Methods: In a prospective study 224 healthy, overweight or obese children aged 1 - 12 years were examined. Body Mass Index-Standard Deviation Score, alanine aminotransferase, aspartate aminotransferase and gamma-glutamyl-transpeptidase were measured. Results: Elevated alanine aminotransferase was observed in 29% of children. 26 % of obese and 30 % of overweight children had liver enzyme elevations. Obese children had significantly higher alanine aminotransferase levels than overweight children (0.9 vs. 0.7 times the Upper Limit of Normal; P = 0.04). Conclusions: Elevation of liver enzymes appears in 29 % obese children in a tertiary care centre. Absolute alanine aminotransferase levels are significantly higher in obese than in overweight children. Even obese children with normal liver enzymes show signs of fatty liver disease as demonstrated by liver enzymes at the upper limit of normal. PMID:24748893

    Identification of modifiable behaviors is important for pediatric weight management and obesity prevention programs. This study examined obesogenic behaviors in children with obesity in a Northern California obesity intervention program using data from a parent/teen-completed intake questionnaire covering dietary and lifestyle behaviors (frequency of breakfast, family meals, unhealthy snacking and beverages, fruit/vegetable intake, sleep, screen time, and exercise). Among 7956 children with BMI ≥ 95th percentile, 45.5% were females and 14.2% were 3–5, 44.2% were 6–11, and 41.6% were 12–17 years old. One-quarter (24.9%) were non-Hispanic white, 11.3% were black, 43.5% were Hispanic, and 12.0% were Asian/Pacific Islander. Severe obesity was prevalent (37.4%), especially among blacks, Hispanics, and older children, and was associated with less frequent breakfast and exercise and excess screen time, and in young children it was associated with consumption of sweetened beverages or juice. Unhealthy dietary behaviors, screen time, limited exercise, and sleep were more prevalent in older children and in selected black, Hispanic, and Asian subgroups, where consumption of sweetened beverages or juice was especially high. Overall, obesity severity and obesogenic behaviors increased with age and varied by gender and race/ethnicity. We identified several key prevalent modifiable behaviors that can be targeted by healthcare professionals to reduce obesity when counseling children with obesity and their parents. PMID:26885385

    The prevalence of childhood overweight and obesity in China has increased in recent decades. However, studies reported from China use several different definitions and growth references, making it difficult to compare the rates of obesity from different regions. It also makes it difficult to establish the extent of secular trends in obesity and to make international comparisons. This article reviews the definitions of childhood obesity used in Chinese studies published over the past 10 years. The majority (79%) of the Chinese studies used a definition of >120% of the mean value of the National Center for Health Statistics reference population to diagnose childhood obesity. Only 7 studies (9%) conducted in China measured childhood obesity using age-specific and sex-specific body mass index (BMI) cutoffs, including International Obesity Task Force cutoffs, Centers for Disease Control 2000 and World Health Organization 2006 BMI curves, and Chinese BMI curves. It is important that a consistent and applicable definition is used and all studies accurately define the obesity with growth reference, cutoff criteria, sample selection, and age distribution. The use of sex-specific and age-specific BMI cutoffs should be considered when undertaking future studies of obesity in Chinese children.

  20. Epidemiological Paradox or Immigrant Vulnerability? Obesity Among Young Children of Immigrants.

    2015-08-01

    According to the "immigrant epidemiological paradox," immigrants and their children enjoy health advantages over their U.S.-born peers--advantages that diminish with greater acculturation. We investigated child obesity as a potentially significant deviation from this paradox for second-generation immigrant children. We evaluated two alternate measures of mother's acculturation: age at arrival in the United States and English language proficiency. To obtain sufficient numbers of second-generation immigrant children, we pooled samples across two related, nationally representative surveys. Each included measured (not parent-reported) height and weight of kindergartners. We also estimated models that alternately included and excluded mother's pre-pregnancy weight status as a predictor. Our findings are opposite to those predicted by the immigrant epidemiological paradox: children of U.S.-born mothers were less likely to be obese than otherwise similar children of foreign-born mothers; and the children of the least-acculturated immigrant mothers, as measured by low English language proficiency, were the most likely to be obese. Foreign-born mothers had lower (healthier) pre-pregnancy weight than U.S.-born mothers, and this was protective against their second-generation children's obesity. This protection, however, was not sufficiently strong to outweigh factors associated or correlated with the mothers' linguistic isolation and marginal status as immigrants.

    The increased prevalence of obesity in children and its complications have led to a greater interest in studying baroreflex sensitivity (BRS) in children. This review of BRS in children and adolescents includes subtopics on: 1. Resting values of BRS and their reproducibility, 2. Genetics of BRS, 3. The role of a primarily low BRS and obesity in the development of hypertension, and 4. Association of diabetes mellitus, BRS, and obesity. The conclusions specific to this age follow from this review: 1. The mean heart rate (HR) influences the measurement of BRS. Since the mean HR decreases during adolescence, HR should be taken into account. 2. A genetic dependency of BRS was found. 3. Low BRS values may precede pathological blood-pressure elevation in children with white-coat hypertension. We hypothesize that low BRS plays an active role in the emergence of hypertension in youth. A contribution of obesity to the development of hypertension was also found. We hypothesize that both factors, a primarily low BRS and obesity, are partially independent risk factors for hypertension in youths. 4. In diabetics, a low BRS compared to healthy children can be associated with insulin resistance. A reversibility of the BRS values could be possible after weight loss.

    The present survey aims at determining the prevalence of extreme obesity (defined as a body mass index (BMI) ≥ 99.5th percentile) for the first time in Austria and at investigating the relationship between weight status and mother tongue in a representative Viennese sample of 24,989 children and adolescents (2-16 years) with a percentage of approximately 46 % of migration background.Directly measured anthropometric data on body weight and height were collected and BMI was calculated. Prevalence of overweight, obesity and extreme obesity was determined for every subgroup according to mother tongue using the German national reference criteria by Kromeyer-Hauschild et al.In this sample, 2.1 % of all children and adolescents had to be classified as being extremely obese. More boys (2.3 %) than girls (1.9 %) suffered from extreme obesity (p = 0.048). Total 1.7 % of children and adolescents with German as their native language, 2.5 % of Turkish native speakers and 2.9 % of children and adolescents with another mother tongue were extremely obese (p ≤ 0.001). The highest prevalence of overweight or obesity was found in Turkish-native-speaking children and adolescents (p ≤ 0.001), whereas the lowest one was found in German-native-speaking children and adolescents (p ≤ 0.001).This large study clearly shows that extreme obesity is a common disease and largely neglected. Apparently, another native language than German, as an indicator for a migration background, may be associated with a substantially higher probability for the development of extreme obesity in Vienna, Austria. Thus, effective preventive measures to overcome obesity are urgently needed.

    Paediatric overweight continues to be a public health problem, and the etiology of obesity is multifactorial and complex. Dietary patterns, physical activity (PA) and sedentary behaviors are acknowledged as major behavioural determinants of obesity. New technologies and electronic based activities have produced a decrease in PA levels, and an increase in sedentary activities in children and adolescents. Potential mechanisms that explain the association between TV viewing and childhood obesity are: displacement of PA, unhealthy food preferences produced by food advertisements, a higher energy intake by automatic eating and overconsumption caused by distraction. Interventions aimed to reduce time in sedentary behaviours are in children generally positive. However, their benefits on adiposity markers are small. Thus, if global and macro-level obesogenic factors are not changed substantially, the interventions oriented to prevent obesity will produce small benefits.

    Overweight and obesity affects 1 in 3 US children and adolescents. Clinical recommendations have largely focused on screening guidelines and counseling strategies. However, the physical examination of the child or adolescent with obesity can provide the clinician with additional information to guide management decisions. This expert-based review focuses on physical examination findings specific to children and adolescents with obesity. For each physical examination element, the authors define the finding and its prevalence among pediatric patients with obesity, discuss the importance and relevance of the finding, describe known techniques to assess severity, and review evidence regarding the need for additional evaluation. The recommendations presented represent a comprehensive review of current evidence as well as expert opinion. The goal of this review is to highlight the importance of conducting a targeted physical examination during pediatric weight management visits.

    There are relatively low rates of screening for overweight and obesity among children and adolescents in primary care. A simplified method for such screening is needed. The study objective was to examine if weight-for-age percentiles are sufficiently sensitive in identifying overweight and obesity in children and adolescents. We used data from two distinct sources: four consecutive cycles of the National Health and Nutrition Examination Surveys (NHANES) from the years 2005 to 2012, using participants aged 2-17.9 years for whom data on age, sex, weight, and height were available (n=12,884), and primary care clinic measurements (n=15,152). Primary outcomes were the threshold values of weight-for-age percentiles which best discriminated between normal weight, overweight, and obesity status. Receiver operating characteristic analyses demonstrated that weight-for-age percentiles well discriminated between normal weight and overweight and between non-obese and obese individuals (area under curve=0.956 and 0.977, respectively, both p<0.001). Following Classification and Regression Trees analysis, the 90th and 75th weight-for-age percentiles were chosen as appropriate cutoffs for obesity and overweight, respectively. These cutoffs had high sensitivity and negative predictive value in identifying obese participants (94.3% and 98.6%, respectively, for the 90th percentile) and in identifying overweight participants (93.2% and 95.9%, respectively, for the 75th percentile). The sensitivities and specificities were nearly identical across race and sex, and in the validation data from NHANES 2011 to 2012 and primary care. We conclude that weight-for-age percentiles can discriminate between normal weight, overweight and obese children, and adolescents. The 75th and 90th weight-for-age percentiles correspond well with the BMI cutoffs for pediatric overweight and obesity, respectively.

    Aims: To test for the coexistence of social inequalities in undernutrition and obesity in preschool children. Methods: Retrospective, cross sectional, study of routinely collected data from 74 500 children aged 39–42 months in 1998/99. Main outcome measures were weight, height, sex, and age routinely recorded by health visitors. Body mass index (BMI) standardised for age and sex, relative to UK 1990 reference data, was used to define undernutrition (BMI <2nd centile) and obesity (BMI >95th centile; BMI >98th centile). Social deprivation was assessed as Carstairs deprivation category (1 = most affluent to 7 = most deprived). Results: Both undernutrition (3.3%) and obesity (8.5% above 95th centile; 4.3% above 98th centile) significantly exceeded expected frequencies from UK 1990 reference data. Undernutrition and obesity were significantly more common in the more deprived families. Odds ratios in deprivation category 7 relative to category 1 were 1.51 (95% CI 1.22 to 1.87) for undernutrition (BMI <2nd centile) and 1.30 (95% CI 1.05 to 1.60) for obesity (BMI >98th centile). The cumulative prevalence of under and overnutrition (malnutrition) in the most deprived group was 9.5% compared to 6.9% in the least deprived group. Conclusions: Undernutrition and obesity are significantly more common than expected in young children and strongly associated with social deprivation. Both undernutrition and obesity have adverse short and long term health effects. Public health strategies need to tackle malnutrition (both undernutrition and obesity) in children and take into consideration the association with social deprivation. PMID:12876159

    Fat mass content, fat distribution, and fat-mass and obesity associated (FTO) gene have been reported among a broad spectrum of genetic variation connected with body weight. The aim of our study was to investigate whether the T/A rs9939609 polymorphism of the FTO gene may influence obesity and metabolic indices in children. A 160 children were examined (136 obese and 24 non-obese). The anthropometric measurements and calculations included: height, weight, waist and hip circumference, sum of the thickness of 3 and 10 skin folds, % of fat content, % FAT- BIA , % LBM-BIA. BMI, SDS of BMI, WHR, and WHtR. Fasting plasma total cholesterol (TC), HDL and LDL-cholesterol, triglycerides (TG), oral glucose tolerance test (OGTT), and HOMA-IR were analyzed and the blood pressure were measured. The rs9939609 polymorphism of FTO gene was genotyped by allele-specific real-time polymerase chain- reaction (RT-PCR). We found that the mean concentrations of TC, TG, LDLC, and HOMA-IR were significantly higher, and HDL was lower in the obese than in non-obese children. The presence of TT, but not AA alleles, related to the percentage of fat content, BMI, and z-score of BMI. None of the other anthropometric indices did differ between the children with gene polymorphism and wild homozygous. In conclusion, rs9939609 polymorphism in the fat-mass and obesity-associated gene is associated with BMI and the percent of fat content in children.

    Background: The association of obesity and lean mass (LM) has not been examined well in children and adolescents, and it remains controversial. Objective: The objective of this study was to evaluate the relationship of body mass index (BMI) categories and regional obesity with total and regional LM in children and adolescents. Methods: A total of 1408 children and adolescents (boys 58.9%; girls 41.1%) divided according to BMI (normal weight 79.5%, overweight 16.0%, and obese 4.5%) were included in this cross-sectional study. Total and regional LM and fat mass were measured by DXA. Leg and arm fat-to-total fat ratio (LATR) indicative of subcutaneous fat and trunk fat-to-total fat ratio (TTR), an indicator of visceral fat, were calculated. Results: Mean age of the study population was 13.2 ± 2.7 years (boys - 13.0 ± 2.7; girls - 13.4 ± 2.8 years). Total LM (TLM) and its regional distribution were higher in overweight and obese groups when compared with those with normal BMI in both genders. TLM was comparable between overweight and obese in both genders. TLM per unit of fat progressively decreased from normal to obese categories. The difference in LM per unit fat between BMI categories persisted after adjustment for age, height, and sexual maturity score. TLM increased across the quartiles of TTR, but decreased with an increment in subcutaneous fat (quartiles of LATR). Conclusions: Obese children and adolescents apparently have higher LM than normal BMI children, but have lower LM per unit of fat. Subcutaneous fat had a negative impact and visceral fat had a positive impact on TLM. PMID:27867879

    Background Recent studies suggest that adolescent adiposity is established already in preadolescence. Earlier studies have confirmed a strong tracking of obesity from adolescence to adulthood. Our aim was to examine the diagnostic accuracy of a population-derived protocol for identification of preschool children at risk for obesity in preadolescence. Methodology/Principal Findings We analysed data obtained for child health surveillance up to age 5 from 5778 children born in a Swedish county in 1991. The basic data set included age, sex, and weight and height measurements from the regular checkups between ages 1.5 and 5. Data not routinely collected in the child health centre setting were disregarded. The children were at age 10 randomly assigned to protocol derivation and validation cohorts and assessed for obesity according to IOTF criteria. The accuracy of predicting obesity in the validation cohort was measured using decision precision, specificity, and sensitivity. The decision protocol selected 1.4% of preschool children as being at obesity risk. The precision of the protocol at age 10 was 82% for girls and 80% for boys, and the specificity was 100% for both boys and girls. The sensitivity was higher for girls (41%) than for boys (21%). The relative risk for obesity at age 10 estimated by the odds ratio for individuals selected by the protocol compared to non-selected peers was 212.6 (95% confidence interval 56.6 to 798.4) for girls and 120.3 (95% CI 24.5 to 589.9) for boys. Conclusion/Significance A simple and inexpensive decision protocol based on BMI values proved to have high precision and specificity for identification of preschool children at risk for obesity persisting into adolescence, while the sensitivity was low especially for boys. Implementation and further evaluations of the protocol in child health centre settings are warranted. PMID:17579709

    Obesity is known to lead to complications involving several systems. The basic mechanism in obesity-related complications is chronic inflammation and increased oxidative stress. Trace element levels in obese children may vary due to poor nutritional habits. The purpose of this study was to investigate the relation between serum paraoxonase (PON1) and arylesterase (ARE) levels, markers of the oxidant-antioxidant balance in the body, and serum zinc (Zn), copper (Cu), manganese (Mn), and selenium (Se) concentrations in obese children. Fifty-seven overweight patients aged 6-17 and 48 age- and sex-matched healthy children were included in the study. Serum PON1 and ARE activity levels were measured, together with Cu, Zn, Mn, Se, total cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein, very low-density lipoprotein, glucose, aspartate amino transferase, and alanine amino transferase levels. PON1 and ARE activity levels were significantly lower in obese patients compared to those in healthy individuals (P < 0.05). Various changes were determined in Cu, Zn, Mn, and Se levels between the study and control groups (P < 0.05). In terms of the relation between trace elements and PON1 and ARE levels, a significant positive correlation was determined between serum Se and PON1 levels in the study group (P < 0.05, r = 0.31). No significant correlation was determined between other trace element levels and PON1 and ARE levels (P > 0.05). In conclusion, the detection in our study of a positive correlation between Se and PON1 levels in obese children may be significant in terms of showing a relation between Se and antioxidant systems in obese children.

    American Indian (AI) children have the highest rates of obesity among ethnic groups in the United States, and rates continue to increase. This study was designed to examine the effects of prenatal and early postnatal factors on AI children's body mass index (BMI) trajectories, adiposity, and cardiovascular risk markers during early childhood. We screened 471 AI children (ages 5-8) from three Wisconsin tribes. Screenings included anthropometric and body fat measures and non-fasting lipid and glucose via fingerstick blood samples. Tribal records from Women Infants and Children (WIC) programs and clinic charts provided data on children's BMI trajectories, maternal prenatal factors, and the early postnatal feeding environment. Forty-seven percent of children were overweight or obese. Analysis of growth trajectories showed that children's BMI category was largely determined within the 1 year of life. Significant predictors of children's BMI category at age 1 included macrosomia (OR 4.38), excess gestational weight gain (OR 1.64) and early termination of breastfeeding (OR 1.66). Children who were overweight/obese at age 1 had greater odds of being overweight (OR 3.42) or obese (OR 3.36), and having unhealthy levels of body fat (OR 2.95) and LDL cholesterol (OR 1.64) at ages 5-8. Children's BMI category is determined in the early post-natal environment, within the 1 year of life, by factors including excess gestational weight gain and early termination of breastfeeding. In turn, children's BMI category at age 1 predicts the emergence of cardiovascular risk markers in early childhood.

    In obese children, hyperinsulinaemia induces adverse metabolic consequences related to the risk of cardiovascular and other disorders. Branched-chain amino acids (BCAA) and acylcarnitines (Carn), involved in amino acid (AA) degradation, were linked to obesity-associated insulin resistance, but these associations yet have not been studied longitudinally in obese children. We studied 80 obese children before and after a one-year lifestyle intervention programme inducing substantial weight loss >0.5 BMI standard deviation scores in 40 children and no weight loss in another 40 children. At baseline and after the 1-year intervention, we assessed insulin resistance (HOMA index), fasting glucose, HbA1c, 2 h glucose in an oral glucose tolerance test, AA, and Carn. BMI adjusted metabolite levels were associated with clinical markers at baseline and after intervention, and changes with the intervention period were evaluated. Only tyrosine was significantly associated with HOMA (p < 0.05) at baseline and end and with change during the intervention (p < 0.05). In contrast, ratios depicting BCAA metabolism were negatively associated with HOMA at baseline (p < 0.05), but not in the longitudinal profiling. Stratified analysis revealed that the children with substantial weight loss drove this association. We conclude that tyrosine alterations in association with insulin resistance precede alteration in BCAA metabolism. This trial is registered with ClinicalTrials.gov Identifier NCT00435734.

    Objectives Obesity is associated with functional disability in adults with chronic pain, but less is known about obesity among youth with chronic pain. The purpose of this study was to 1) identify the prevalence of overweight and obesity in children and adolescents receiving treatment for chronic pain, and 2) examine associations between Body Mass Index (BMI), pain intensity, and activity limitations in this population. Methods Data was obtained from records of 118 patients, ages 8 to 18, seen in a multidisciplinary pediatric pain clinic. Information about age, gender, pain problem, duration and severity, medical diagnoses, medications, height and weight were collected from medical records and intake questionnaires. The CDC’s pediatric BMI calculator was used to obtain percentile and category (underweight, healthy weight, overweight, obese). Children and parents completed the Child Activity Limitations Interview-21 (CALI-21), a self-report measure of activity limitations. Results A significantly higher rate of overweight and obesity was observed among youth with chronic pain compared to a normative sample. BMI percentile was predictive of concurrent limitations in vigorous activities, according to parent report. Discussion BMI percentile and weight status may contribute to activity limitations among children and adolescents with chronic pain. Weight status is an important factor to consider in the context of treatment of chronic pain and disability in children and adolescents. PMID:20664337

    Obesity has been recognized as a major global public health concern. In particular, childhood obesity is a major risk factor for other health issues, such as type 2 diabetes, in later stages of life. A few earlier studies have associated exposure to endocrine-disrupting chemicals (EDCs) with childhood obesity. There is limited information, however, on exposure to EDCs and childhood obesity in India. In this study, urinary levels of 26 EDCs were determined in 49 obese and 27 non-obese Indian children. Eleven EDCs, including 2,2-bis(4-hydroxyphenyl)propane (BPA), 4,4'-sulfonyldiphenol (BPS), methyl paraben (MeP), ethyl paraben (EtP), propyl paraben (PrP), 4-hydroxybenzoic acid (4-HB), 3,4-dihydroxybenzoic acid (3,4-DHB), triclosan (TCS), benzophenone-3 (BP3), bisphenol A diglycidyl ether (BADGE), and bisphenol A bis(2,3-dihydroxypropyl) glycidyl ether (BADGE·2H2O) were found in >70% of urine samples. No significant associations were found between childhood obesity and most target chemicals studied, except for 3,4-DHB, which showed a significant positive association. Urinary concentrations of 3,4-DHB were higher in obese children than in non-obese children, independent of age, sex, family income, parent education, physical activity, and urinary creatinine. Urinary concentrations of several EDCs were higher in Indian children than the concentrations reported for children in the USA and China. To our knowledge, this is the first study to report urinary concentrations of several EDCs in Indian children.

    2015-01-01

    Abstract Background: The prevalence of overweight and obesity among children and adolescents has increased worldwide and has reached alarming proportions. Currently, sugar-sweetened beverages (SSBs) are the primary source of added sugar in the diet of children and adolescents. Contradictive findings from studies and reviews have fueled an endless debate on the role of SSBs in the development of childhood obesity. Methods: The primary aim of the present review of reviews was to assess how review- and study-level methodological factors explain conflicting results across reviews and meta-analyses by providing an up-to-date synthesis of recent evidence regarding the association between SSB consumption and weight gain, overweight, and obesity in a population of 6-month-old to 19-year-old children and adolescents. The secondary aim was to assess the quality of included reviews using the Assessment of Multiple SysTemAtic Reviews (AMSTAR) measurement tool. Systematic literature reviews and meta-analyses were included. The literature search was performed through the platforms Pubmed/Medline, Cinahl, and Web of Knowledge. Results: Thirteen reviews and meta-analyses were included. Nine reviews concluded that there was a direct association between SSBs and obesity in children and adolescents and four others did not. The quality of the included reviews was low to moderate, and the two reviews with the highest quality scores showed discrepant results. Conclusions: The majority of reviews concluded that there was a direct association between SSB consumption and weight gain, overweight, and obesity in children and adolescents. However, recent evidence from well-conducted meta-analyses shows discrepant results regarding the association between SSB and weight gain, overweight, and obesity among children and adolescents. Improving methodological quality of studies and reviews as well as ensuring responsible conduct of research and scientific integrity is essential for the provision

    Introduction Childhood obesity and overweight is a global epidemics and has been increasing in the developing countries. Childhood obesity is linked with increased mortality and morbidity independent of adult obesity. Declining physical activity, access to junk food and parenting style are the major determinants of overweight in children. Thus, there is a need for increasing the physical activity of children, educating the parents as well as the children on lifestyle modification. This can be achieved through implementation of multicomponent intervention. Aim To evaluate the effectiveness of multicomponent intervention on improving the lifestyle practices, reducing the body fat and improving the self esteem of obese children from selected schools of Udupi District, South India. Materials and Methods A sample of 120 obese children were enrolled for multicomponent intervention. The components of multicomponent intervention were: education provided to the obese children on lifestyle modification, education of the parents and increasing the physical education activity of these children in the form of aerobics under the supervision of physical education teacher. There was an attrition of 25% in the intervention group. Thus the final sample in the intervention group was 90. Total sample of 131 overweight/ obese children enrolled as controls. There was an attrition of 20.61% in the control group. Thus, the final sample in the control group was 104. Intervention group received the multicomponent intervention for six month. Results Mixed Method Repeated measures Ananlysis of Variance (ANOVA) was applied for analysis of data. Results indicated that the intervention was effective in reducing the Body Mass Index (BMI), triceps, biceps, subscapular skin fold thickness of obese children. The intervention was also effective in improving the lifestyle practices and self-esteem of obese children. Conclusion Overweight/obese children need to control diet and perform vigorous

    Obese individuals are blamed for their excess weight based on causal attribution to the individual. It is unclear whether obese individuals of different age groups and gender are faced with the same amount of stigmatization. This information is important in order to identify groups of individuals at risk for higher stigmatization and discrimination. A telephone interview was conducted in a representative sample of 3,003 participants. Experimental manipulation was realized by vignettes describing obese and normal-weight children, adults and senior citizens. Stigmatizing attitudes were measured by semantic differential. Causal attribution was assessed. Internal factors were rated with highest agreement rates as a cause for the vignette's obesity. Lack of activity behavior and eating too much are the most supported causes. Importance of causes differed for the different vignettes. For the child, external causes were considered more important. The overweight vignette was rated consistently more negatively. Higher educational attainment and personal obesity were associated with lower stigmatizing attitudes. The vignette of the obese child was rated more negatively compared to that of an adult or senior citizen. Obesity is seen as a controllable condition, but for children external factors are seen as well. Despite this finding, they are faced with higher stigmatizing attitudes in the general public, contradicting attribution theory assumptions. Internal and external attribution were found to be inter-correlated. Obese children are the population most at risk for being confronted with stigmatization, making them a target point in stigma-reduction campaigns.

    Obesity exhibits a wide variety of electrocardiogram (ECG) abnormalities in adults, which often lead to cardiovascular events. However, there is currently no evidence of an association between obesity and ECG variables in children and adolescents. The present study aimed to explore the associations between obesity and ECG intervals and axes in children and adolescents. A cross-sectional observational study of 5,556 students aged 5–18 years was performed. Anthropometric data, blood pressure and standard 12-lead ECGs were collected for each participant. ECG variables were measured manually based on the temporal alignment of simultaneous 12 leads using a CV200 ECG Work Station. Overweight and obese groups demonstrated significantly longer PR intervals, wider QRS durations and leftward shifts of frontal P-wave, QRS and T-wave axes, while the obese group also demonstrated significantly higher heart rates, compared with normal weight groups within normotensive or hypertensive subjects (P<0.05). Abdominal obesity was also associated with longer PR intervals, wider QRS duration and a leftward shift of frontal ECG axes compared with normal waist circumference (WC) within normotensive or hypertensive subjects (P<0.05). Gender was a possible factor affecting the ECG variables. Furthermore, the ECG variables, including PR interval, QRS duration and frontal P-wave, QRS and T-wave axes, were significantly linearly correlated with body mass index, WC and waist-to-height ratio adjusted for age, gender, ethnicity and blood pressure. However, there was no significant association between obesity and the corrected QT interval (P>0.05). The results of the current study indicate that in children and adolescents, general and abdominal obesity is associated with longer PR intervals, wider QRS duration and a leftward shift of frontal P-wave, QRS and T-wave axes, independent of age, gender, ethnicity and blood pressure.

    Introduction Obesity is a chronic, complex, and multifactorial disease, characterized by excess body fat. Diverse studies of the human genome have led to the identification of susceptibility genes that contribute to obesity. However, relatively few studies have addressed specifically the association between the level of expression of these genes and obesity. Material and methods We studied 160 healthy and obese unrelated Mexican children aged 6 to 14 years. We measured the transcriptional expression of 20 genes associated with obesity, in addition to the biochemical parameters, in peripheral white blood cells. The detection of mRNA levels was performed using the OpenArray Real-Time PCR System (Applied Biosystems). Results Obese children exhibited higher values of fasting glucose (p = 0.034), fasting insulin (p = 0.004), low-density lipoprotein (p = 0.006), triglycerides (p < 0.001), systolic blood pressure and diastolic blood pressure (p < 0.001), and lower values of high-density lipoprotein (p < 0.001) compared to lean children. Analysis of transcriptional expression data showed a difference for ADRB1 (p = 0.0297), ADIPOR1 (p = 0.0317), GHRL (p = 0.0060) and FTO (p = 0.0348) genes. Conclusions Our results suggest that changes in the expression level of the studied genes are involved in biological processes implicated in the development of childhood obesity. Our study contributes new perspectives for a better understanding of biological processes involved in obesity. The protocol was approved by the National Committee and Ethical Committee Board from the Mexican Social Security Institute (IMSS) (IMSS FIS/IMSS/PRIO/10/011). PMID:27695486

    Obesity in children is a major public health concern in the United States. The objectives of the current study were to determine the prevalence of various groups of cutaneous disorders in obese children and adolescents and to compare the use of dermatology services in obese subjects with that those with a normal body mass index (BMI). This was a retrospective, population-based study at the Kaiser Permanente Northern California Managed Healthcare System. The main outcome measures were the relative risk of cutaneous disorders associated with insulin resistance, androgen excess, bacterial infection, fungal infection, viral infection, inflammation, mechanical changes, and other skin conditions (hidradenitis, hyperhidrosis) in three weight groups (normal, overweight, obese) and the number of dermatology visits. A total of 248,775 subjects were included. Bivariate analyses showed a higher proportion of insulin resistance disorders, bacterial infection, fungal infection, inflammatory disorders, mechanical changes, and other skin conditions in obese subjects than in subjects with a normal BMI (p < 0.001). Disorders of androgen excess and viral infection were significantly less common in obese subjects (p < 0.001). Obese subjects had significantly lower odds of having at least one dermatology encounter than subjects with a normal BMI (odds ratio = 0.92, 95% confidence interval 0.88, 0.96, p = 0.003). Early onset obesity is associated with cutaneous disorders characterized by hyperproliferation, inflammation, bacterial and fungal infection, and mechanical changes but lower rates of disorders of androgen excess and viral infection. The use of dermatology services was not greater in obese patients. Heightened recognition and further analysis of adipose tissue as an endocrine organ that is capable of affecting the skin is warranted.

    The childhood obesity epidemic is expected to increase cardiovascular disease risk, but the impact of obesity on vascular function in children is not fully understood. The purpose of this study was to determine the effect of obesity and maturation on vascular function in normal weight (BMI: 25-75 percentile) and obese (BMI: ≥95 percentile) children ages 8-18 years old. Large and small artery elasticity (LAEI and SAEI, respectively), measured by diastolic radial pulsewave contour analysis, and reactive hyperemia index (RHI), measured by peripheral arterial tonometry, were obtained, along with anthropometric and biochemical outcomes, in 61 normal weight and 62 obese children. SAEI and LAEI increased with age and were 30% and 18% higher, respectively, in obese children (P < 0.01). In contrast, reactive hyperemia increased with age in the normal weight group but did not differ between groups. Multivariate modeling was used to select variables that explained differences in vascular outcomes. The best model for LAEI in normal weight children was height alone (r(2) = 0.49), whereas for obese children the best model included height + fat mass (r(2) = 0.40). For SAEI, there were no significant models for normal weight children, but for obese children the best model included lean mass + fat mass (r(2) = 0.36). Obese children had greater lean and fat mass, and more advanced Tanner stages than their normal weight peers. The increased elasticity observed in obese children appears to reflect accelerated growth and maturation without affecting vascular reactivity measured by reactive hyperemia. Longitudinal follow up will be essential in determining effects on future vascular disease risk.

    Anthropometric characteristics, particularly body mass, are important factors in the development and progression of varus/valgus angular deformities of the knee and have long-term implications including increased risk of osteoarthritis. However, information on how excessive body weight affects the biomechanics of dynamic activities in children is limited. The purpose of this study was to test the hypothesis that during stair-walking lower extremity joint moments normalized to body mass in obese children are greater than those in normal-weight children. Eighteen obese children (10.5±1.5 years, 148±10cm, 56.6±8.4kg) and 17 normal-weight children (10.4±1.3 years, 143±9cm, 36.7±7.5kg) were recruited. A Vicon system and two AMTI force plates were used to record and analyze the kinematics and kinetics of ascending and descending stairs. Significant differences in spatio-temporal, kinematic and kinetic parameters during ascending and descending stairs between obese and normal-weight children were detected. For stair ascent, greater hip abduction moments (+23%; p=0.001) and greater knee extension moments (+20%; p=0.008) were observed. For stair descent, smaller hip extension moment (-52%; p=0.031), and greater hip flexion moments (+25%; p=0.016) and knee extension moments (+15%, p=0.008) were observed for obese subjects. To date, it is unclear if and how the body may adapt to greater joint moments in obese children. Nevertheless, these differences in joint moments may contribute to a cumulative overloading of the joint through adolescence into adulthood, and potentially result in a greater risk of developing knee and hip osteoarthritis.

    Objectives. We investigated the association between physical and social neighborhood environments and fifth-grade students’ physical activity and obesity. Methods. We collected data on 650 children and their primary caregivers during phase 1 of Healthy Passages, a multisite, community-based, cross-sectional study of health risk behaviors and health outcomes in children. We conducted independent systematic neighborhood observations to measure neighborhood physical characteristics, and we analyzed survey data on social processes. We modeled children's physical activity and obesity status with structural equation models that included latent variables for the physical and social environments. Results. After we controlled for children's sociodemographic factors, we found that a favorable social environment was positively associated with several measures of physical activity and that physical activity was negatively associated with obesity in these children. Physical environment was not significantly associated with physical activity. Conclusions. Our findings suggest that neighborhood social factors as well as the physical environment should be considered in the development of health policy and interventions to reduce childhood obesity.

    Objective. The objective of this study was to evaluate whether duration of breastfeeding is associated with a lower prevalence of metabolic syndrome in obese children. Methods. A retrospective analysis of obese children aged 3 to 18 years followed at a pediatric outpatient clinic at a single center between the years 2008 and 2012. The children were divided according to their breastfeeding duration: no breastfeeding, a short period of breastfeeding, and a long term breastfeeding. Also, they were divided into metabolic and nonmetabolic syndrome groups, based on physical examination and laboratory tests. Results. Out of 4642 children who visited the clinic, 123 were obese and were included in the study. About half of them matched the metabolic syndrome criteria. There was no correlation between the prevalence of metabolic syndrome and the duration of breastfeeding. Hypertension, abnormal low levels of HDL, high levels of HbA1c, and high fasting triglyceride levels were very common in our study population, yet no statistical significance was noted among the different breastfeeding groups. Conclusion. In this study, breastfeeding was not associated with a reduced risk for metabolic syndrome, compared with formula feeding, in children who are obese. PMID:26295060

    Background Overweight and obesity are increasing health problems that are not restricted to adults only. Childhood obesity is associated with metabolic, psychological and musculoskeletal comorbidities. However, knowledge about the effect of obesity on the foot function across maturation is lacking. Decreased foot function with disproportional loading characteristics is expected for obese children. The aim of this study was to examine foot loading characteristics during gait of normal-weight, overweight and obese children aged 1–12 years. Methods A total of 10382 children aged one to twelve years were enrolled in the study. Finally, 7575 children (m/f: n = 3630/3945; 7.0±2.9yr; 1.23±0.19m; 26.6±10.6kg; BMI: 17.1±2.4kg/m2) were included for (complete case) data analysis. Children were categorized to normal-weight (≥3rd and <90th percentile; n = 6458), overweight (≥90rd and <97th percentile; n = 746) or obese (>97th percentile; n = 371) according to the German reference system that is based on age and gender-specific body mass indices (BMI). Plantar pressure measurements were assessed during gait on an instrumented walkway. Contact area, arch index (AI), peak pressure (PP) and force time integral (FTI) were calculated for the total, fore-, mid- and hindfoot. Data was analyzed descriptively (mean ± SD) followed by ANOVA/Welch-test (according to homogeneity of variances: yes/no) for group differences according to BMI categorization (normal-weight, overweight, obesity) and for each age group 1 to 12yrs (post-hoc Tukey Kramer/Dunnett’s C; α = 0.05). Results Mean walking velocity was 0.95 ± 0.25 m/s with no differences between normal-weight, overweight or obese children (p = 0.0841). Results show higher foot contact area, arch index, peak pressure and force time integral in overweight and obese children (p<0.001). Obese children showed the 1.48-fold (1 year-old) to 3.49-fold (10 year-old) midfoot loading (FTI) compared to normal-weight. Conclusion Additional

    Obesity is associated with health consequences, and thyroid dysfunction may be an adaption to the increased energy expenditure in obesity. With the rising prevalence of obesity in childhood, the prevalence of metabolic syndrome may also increase. In the current study, we have shown gender differences in the association of thyroid hormones with obesity, and attempted to elucidate the relationship between thyroid hormones and anthropometric parameters and biochemical data in obese Japanese children. We analyzed anthropometric measurements, blood pressure, body composition, thyroid hormones, and lipid profiles in 283 obese children. The association between thyroid hormones and several parameters differed by gender. The free T3 to free T4 ratio (fT3/fT4) in boys was negatively associated with the quantitative insulin sensitivity check index, whereas in girls, thyroid-stimulating hormone levels were positively correlated with levels of glucose, diastolic blood pressure, and non-high density lipoprotein-cholesterol, and fT3/fT4 was positively correlated with uric acid levels. FT3/fT4 in boys with metabolic syndrome was relatively higher than in those without metabolic syndrome. The cause of gender differences is unknown. Therefore, further studies with larger sample sizes and a long-term follow-up period are needed to address the influence of thyroid hormones on various parameters.

    Background. Childhood obesity is becoming a global epidemic which may result in increased morbidity and mortality during young adulthood. Objectives. To identify factors associated with overweight and that of obesity among Kuwaiti elementary male school children aged 6-10 years. Methods. Weights and heights of 662 students at a randomly selected school were collected to obtain body mass index (BMI). Results. The prevalence of overweight and obesity among the students were 20.2% and 16.8%, respectively. There were a variety of factors associated with overweight and obesity; however, having one or more obese brother, an unemployed father, or a high (>11) number of persons living at home was significantly associated with higher risk of overweight and obesity. Increased age and school level as well as having a chronic disease were associated with the risk of overweight. Conclusion. Health education programs for families should be implemented to help control overweight and obesity in Kuwaiti children.

    Although the histologic appearance of pure testicular teratomas (PTTs) is similar in children and adults, the prognosis is dramatically different. Prepubertal PTTs are rare, with a benign clinical course, whereas the adult cases typically have malignant outcomes. Chromosome 12p abnormalities are seen in most adult testicular germ cell tumors but have not been found in prepubertal PTTs. IMP3 is an oncofetal protein that is highly expressed in many malignancies. Recently, we demonstrated IMP3 is expressed in adult mature testicular teratomas but not in mature ovarian teratomas. The aim of this study was to evaluate prepubertal PTTs for chromosome 12p abnormalities and expression of IMP3. A total of 11 cases (excision, n=1; orchiectomy, n=10) were obtained from the surgical pathology archives of 2 large medical centers (1957-2013). All 11 cases were investigated for isochromosome 12p and 12p copy number gain using interphase fluorescence in situ hybridization analysis and were examined by immunohistochemistry for IMP3 expression. Patients ranged in age from 0.9 to 7.0 (mean, 2.4) years. A positive immunohistochemical stain for IMP3 (cytoplasmic staining) was identified in 5 (46%) of 11 cases. Isochromosome 12p was detected in 2 cases (18%) that also expressed IMP3. Somatic copy number alterations of 12p were not observed (0%). We are the first to describe 12p abnormalities and IMP3 expression in prepubertal PTTs. Our data demonstrate a small subset of PTTs harbor typical molecular alterations observed in adult testicular germ cell tumors. Although prepubertal PTTs are considered to be benign neoplasms, it may be a heterogeneous group.

    OBJECTIVE: To evaluate the association between calcium intake and serum vitamin D levels and childhood obesity by an integrative review. DATA SOURCE: The research was conducted in the databases PubMed/medLine, Science Direct and SciELO with 2001 to 2014 publications. We used the combined terms in English: ''children'' and ''calcium'' or ''children'' and ''vitamin D'' associated with the descriptors: ''obesity'', ''adiposity'' or ''body fat'' for all bases. Cross-sectional and cohort studies, as well as clinical trials, were included. Review articles or those that that have not addressed the association of interest were excluded. DATA SYNTHESIS: Eight articles were part of this review, five of which were related to calcium and three to vitamin D. Most studies had a longitudinal design. The analyzed studies found an association between calcium intake and obesity, especially when age and sex were considered. Inverse relationship between serum vitamin D and measures of adiposity in children has been observed and this association was influenced by the sex of the patient and by the seasons of the year. CONCLUSIONS: The studies reviewed showed an association between calcium and vitamin D with childhood obesity. Considering the possible protective effect of these micronutrients in relation to childhood obesity, preventive public health actions should be designed, with emphasis on nutritional education.

    Background Obesity the epidemic of our times appears to be a problem that is easy to resolve: just eat less and move more. However, this very common condition has turned out to be extremely troublesome, and in some cases even irreversible. Methods The interplay between less muscle and more fat tissue is discussed from physiological perspectives with an emphasis on the early years of childhood. Results It is suggested that the coordinated muscle-fat interactions lead to a fluctuating exchange economy rate. This bodily economic decision, slides between thrift (more fat) and prodigal (more muscle) strategies. The thrift strategy results not only in obesity and less physical activity but also in other maladies which the body is unable to manage. What leads to obesity (less muscle, more fat) might be very difficult to reverse at adulthood, prevention at childhood is thus recommended. Conclusion Early recognition of the ailment (low muscle mass) is crucial. Based on studies demonstrating a 'rivalry' between muscle build-up and height growth at childhood, it is postulated that among the both taller and more obese children the percentage of children with lower muscle mass will be higher. A special, body/muscle-building gymnastics program for children is suggested as a potential early intervention to prevent the ill progress of obesity. PMID:17166286

    Abstract Objective: To assess the effects of obesity on lung volume and capacity in children and adolescents. Data source: This is a systematic review, carried out in Pubmed, Lilacs, Scielo and PEDro databases, using the following Keywords: Plethysmography; Whole Body OR Lung Volume Measurements OR Total Lung Capacity OR Functional Residual Capacity OR Residual Volume AND Obesity. Observational studies or clinical trials that assessed the effects of obesity on lung volume and capacity in children and adolescents (0-18 years) without any other associated disease; in English; Portuguese and Spanish languages were selected. Methodological quality was assessed by the Agency for Healthcare Research and Quality. Data synthesis: Of the 1,030 articles, only four were included in the review. The studies amounted to 548 participants, predominantly males, with sample size ranging from 45 to 327 individuals. 100% of the studies evaluated nutritional status through BMI (z-score) and 50.0% reported the data on abdominal circumference. All demonstrated that obesity causes negative effects on lung volume and capacity, causing a reduction mainly in functional residual capacity in 75.0% of the studies; in the expiratory reserve volume in 50.0% and in the residual volume in 25.0%. The methodological quality ranged from moderate to high, with 75.0% of the studies classified as having high methodological quality. Conclusions: Obesity causes deleterious effects on lung volume and capacity in children and adolescents, mainly by reducing functional residual capacity, expiratory reserve volume and residual volume.

    Childhood obesity is on the rise worldwide and its increasing prevalence in low and middle income countries is well-known. Obesity interventions have the potential to prevent adverse health outcomes; however, large gaps in research and knowledge about the efficacy and sustainability of such interventions remain. The objectives of this article were to review the evidence for interventions to prevent and control obesity among children and adolescents, evaluate their applicability in India, and discuss the challenges to sustain such interventions. The authors reviewed published research focusing on childhood obesity interventions, especially in India and other lower-resource countries. Nine observational and 10 interventional studies were reviewed. Most studies identified were from developed countries and took place at day-care settings, schools, and after school programs. Nineteen reported studies were grouped into categories: diet (2), physical activity (4), childcare programs (2), media-based programs (2), parental involvement (2), multi-component studies (1), and screen time (6). Most interventions were effective in reducing BMI, decreasing sedentary behaviors, and increasing physical activity. Sustainability of these interventions was not evaluated. While there is no one method or simple intervention to address obesity, multi-component approaches involving home and school environments are promising and warrant evaluation in India. Literature on obesity prevention and control in India and in lower-resource countries, however, is sparse. Existing gaps in knowledge about obesity should be addressed by conducting research in India and carrying out interventions to determine what strategies will be successful and sustainable locally.

    The prevalence of childhood overweight and obesity in the United States has resulted in a number of school-based health interventions. This article provides a review of research that addressed childhood overweight and obesity in minority, U.S. elementary schools. All studies reported some benefits in health behaviors and/or anthropometric measures. Effectiveness was greater when program objectives were specific, implemented across the school environments, extended into the community, and were culturally relevant. Because minority school children are disproportionately affected by overweight and obesity and poor health behaviors, and since schools may be the primary setting to address childhood overweight and obesity in communities, school nurses can be an advocate for school-based programs and facilitate success.

    Context In the past, nutritional deficiencies were common among homeless families. Because obesity is currently a major public health issue in the United States, it is possible that obesity has supplanted nutritional deficiencies as the “new malnutrition” of the homeless. Objective To perform a pilot study to determine the nutritional status of homeless caregivers and their children in the Baltimore City, Maryland. Design Determination of weight, height, and body mass index (BMI) (weight in kg/height in m2) of all subjects and correlation with demographic variables. Setting Six homeless shelters and transitional houses in Baltimore City. Patients Thirty-one caregivers and 60 children. Main Outcome Measures Relationship between caregiver BMI and child BMI and comparison of our data to National Health and Nutrition Examination Survey (NHANES) norms. Results Forty-two percent of the children (25 of 60) had a BMI-for-age classifying them as at risk for overweight (18%) or overweight (23%). None were underweight. One hundred percent of girls and 88% of boys under age 7 years were in the normal range for BMI. There were no caregivers in the underweight range for BMI. Seventy-seven percent were either overweight (26%) or obese (51%). When the weight categories of the largely African-American homeless Baltimore caregivers and their children were compared with national data from NHANES 1999–2002 for both African-American poor and nonpoor adult females and children, the Baltimore subjects had the lowest proportion in the healthy range and the highest proportion in the obese (adults) and overweight (children) categories. Caregiver BMI correlated with child BMI: r = 0.43, P = .0002. Conclusion Our data suggest that overweight and obesity are the major forms of malnutrition in homeless families. PMID:17435649

    Background Schools represent a key potential venue for addressing childhood obesity. Objective To assess the feasibility of Power-Up, an after-school program to decrease obesity risk among African American children, using community-based participatory research (CBPR) principles. Methods Teachers led 14 weekly nutrition and physical activity sessions during after-school care at the Woodlawn Community School on Chicago’s South Side. Forty African American children ages 5 to 12 participated; their 28 parents discussed similar topics weekly at pickup time, and families practiced relevant skills at home. Pre- and post-intervention anthropometrics, blood pressure, dietary measures, and health knowledge and beliefs for children and parents were compared in univariate analysis. Results At baseline, 26% of children were overweight; 28% were obese. Post-intervention, mean body mass index (BMI) z scores decreased from 1.05 to 0.81 (p < .0001). Changes were more pronounced for overweight (−0.206 z-score units) than for obese children (−0.062 z-score units; p = .01). Girls decreased their combined prevalence of overweight/obesity from 52% to 46%; prevalence across these categories did not change for boys. The prevalence of healthful attitudes rose, including plans to “eat more foods that are good for you” (77% to 90%; p = .027) and “planning to try some new sports” (80% to 88%; p = .007). Conclusion Children in the Power-Up program reduced mean BMI z scores significantly. The after-school venue proved feasible. The use of CBPR principles helped to integrate Power-Up into school activities and contributed to likelihood of sustainability. Engaging parents effectively in the after-school time frame proved challenging; additional strate gies to engage parents are under development. Plans are underway to evaluate this intervention through a randomized study. PMID:22616204

    2016-01-01

    Background: There is limited evidence on which risk factors attenuate income inequalities in child overweight and obesity; whether and why these inequalities widen as children age. Method: Eleven thousand nine hundred and sixty five singletons had complete data at age 5 and 9384 at age 11 from the Millennium Cohort Study (UK). Overweight (age 5 : 15%; age 11 : 20%) and obesity (age 5 : 5%; age 11 : 6%) were defined using the International Obesity Taskforce body mass index cut-points. To measure socioeconomic inequalities, we used quintiles of family income and as risk factors, we considered markers of maternal health behaviours and of children’s physical activity, sedentary behaviours and diet. Binary and multinomial logistic regression models were used. Results: The unadjusted analyses revealed stark income inequalities in the risk of obesity at age 5 and 11. At age 5, children in the bottom income quintile had 2.0 (95% CI: 1.4–2.8) increased relative risk of being obese whilst at age 11 they had 3.0 (95% CI: 2.0–4.5) increased risk compared to children in the top income quintile. Similar income inequalities in the risk of overweight emerged by age 11. Physical activity and diet were particularly important in explaining inequalities. Income inequalities in obesity and overweight widened significantly between age 5 and 11 and a similar set of risk factors protected against upward and promoted downward movements across weight categories. Conclusions: To reduce income inequalities in overweight and obesity and their widening across childhood the results support the need of early interventions which take account of multiple risk factors.

    Introduction Obesity-related comorbidities are present in young obese children, providing a platform for early adult cardiovascular disorders. Objectives To compare and correlate markers of adiposity to metabolic disturbances, vascular and cardiac morphology in a European pediatric obese cohort. Methods We carried out an observational and transversal analysis in a cohort consisting of 121 obese children of both sexes, between the ages of 6 and 17 years. The control group consisted of 40 children with normal body mass index within the same age range. Markers of adiposity, plasma lipids and lipoproteins, homeostasis model assessment-insulin resistance, common carotid artery intima-media thickness and left ventricular diameters were analyzed. Results There were statistically significant differences between the control and obese groups for the variables analyzed, all higher in the obese group, except for age, high-density lipoprotein cholesterol and adiponectin, higher in the control group. In the obese group, body mass index was directly correlated to left ventricular mass (r=0.542; p=0.001), the homeostasis model assessment-insulin resistance (r=0.378; p=<0.001) and mean common carotid artery intima-media thickness (r=0.378; p=<0.001). In that same group, insulin resistance was present in 38.1%, 12.5% had a combined dyslipidemic pattern, and eccentric hypertrophy was the most common left ventricular geometric pattern. Conclusions These results suggest that these markers may be used in clinical practice to stratify cardiovascular risk, as well as to assess the impact of weight control programs. PMID:25993589

    Both obesity and asthma are highly prevalent, complex diseases modified by multiple factors. Genetic, developmental, lung mechanical, immunological and behavioural factors have all been suggested as playing a causal role between the two entities; however, their complex mechanistic interactions are still poorly understood and evidence of causality in children remains scant. Equally lacking is evidence of effective treatment strategies, despite the fact that imbalances at vulnerable phases in childhood can impact long-term health. This review is targeted at both clinicians frequently faced with the dilemma of how to investigate and treat the obese asthmatic child and researchers interested in the topic. Highlighting the breadth of the spectrum of factors involved, this review collates evidence regarding the investigation and treatment of asthma in obese children, particularly in comparison with current approaches in 'difficult-to-treat' childhood asthma. Finally, the authors propose hypotheses for future research from a systems-based perspective.

    2010-07-01

    Diet is of major interest in research on the etiology of obesity. Research in this field comprises investigation of the role of individual nutrients and foods, nutrient composition, as well as dietary patterns and habits. Longitudinal data on the association between dietary factors and the development of obesity in childhood and adolescence are sparse; therefore, conclusions on the impact of energy density, consumption of carbohydrates and proteins, snack foods and fast food, meal patterns and speed of eating cannot be drawn. More data exist with respect to the role of energy intake and consumption of fat and sugar-sweetened beverages; however, findings are inconsistent. This could be due to methodological shortcomings that mark dietary assessment in children and adolescents. However, as a direct modulator of energy balance, diet still needs to be part of a comprehensive strategy to combat overweight and obesity in children and adolescents.

    Objective The objective of this study was to identify associations in the prevalence of overweight, obesity and high blood pressure between children and their parents, as well as their eating and physical patterns. Methods In this cross-sectional study, we obtained data on 83 pairs of school-aged children and one of their parents relating to dietary habits and various physical parameters, including the body mass index (BMI) and blood pressure of the children, which were adjusted by age and gender. Both the children and the parents were asked to complete a questionnaire aimed at providing measures of eating behavior. The questions focused on the consumption of fruit and vegetables and soda drinks as well as on physical activity patterns. Parent BMI was calculated from self-reported height and weight values. Results Obesity was diagnosed in 10.8% of the children, and the prevalence of overweight was 28.9%. There was a relationship between a child’s weight status and that of his/her parent according to the BMI; 45% of overweight/obese children had overweight/obese parents. In addition, a parent’s fruit and vegetable consumption was associated with his/her child’s fruit and vegetable consumption (r = 0.47, p < 0.001), and both were associated with soda drink consumption in both parents and children (r = 0.30, p < 0.001). Conclusion Our results confirmed that there is a relationship between the weight status, fruit and vegetable consumption and soda drink intake of children and those of their parents. PMID:21432567

    Diet and physical activity (PA) are essential components of nutritional status. Adequate nutrition and an active lifestyle are key factors during childhood, because food habits track into adulthood. Children spend more time in school than in any other environment away from home. Studying the diet factors and patterns of PA that affect obesity risk in children during school hours and the complete school day can help identify opportunities to lower this risk. We directly measured the time children spent performing moderate to vigorous PA (MVPA) at school, compared the amount and intensity of PA during school hours with after-school hours, and tried to determine if diet behaviors and PA or inactivity were associated with excess weight and body fat. This cross-sectional study included 143 normal-weight (NLW) and 48 obese children aged 8–10 y. Diet data were obtained from two 24-h recalls. Body composition was measured by bioimpedance. Screen time and sports participation data were self-reported. NLW children drank/ate more dairy servings than the obese children, who consumed more fruit-flavored water than the NLW group. Consumption of soft drinks, sugar-added juices, and fresh juices was low in both groups. Children were less active during school hours than after school. MVPA was lower during school hours in the obese group than in the NLW group. Schools, parents, and authorities should be more involved in promoting strategies to improve the dietary habits and PA levels of school-aged children, because this group is not achieving the recommended level of daily MVPA.

    The rise in the rate of obesity in school-aged children, adolescents, and young adults in the last 30 years is a clear healthcare crisis that needs to be addressed. Despite recent national reports in the United States highlighting positive downward trends in the rate of obesity in younger children, we are still faced with approximately 12.7 million children struggling with obesity. Given the immediate and long-term health consequences of obesity, much time and effort has been expended to address this epidemic. Yet, despite these efforts, we still only see limited, short-term success from most interventions. Without changes to how we address childhood obesity, we will continue to see inadequate improvements in the health of our children. Clinicians and researchers need to be lobbying for evidence-based policy changes, such as those identified by systems science, in order to improve the nation's health.

    In this study, we evaluated the risk factors associated with overweight and obesity in 2,640 preschool children in Italy taking into account the ethnic background of the parents. Height and weight were measured and BMI was calculated. Personal and lifestyle data for the children (birth weight, type of breastfeeding, sleep duration, skipping breakfast, snacking, physical activity) and parents (ethnicity, educational level, occupation, weight, height) were collected by means of a questionnaire. Italian and Other European children generally showed the highest percentage of normal weight, while the other ethnic groups presented a greater imbalance. Overweight and obesity were high in African males, who also presented high birth weight. Breastfeeding was most common, although formula feeding was significantly higher in Italians than in immigrants. Immigrants, particularly males, tended to skip breakfast more than Italians. Physical activity was significantly higher in Italians than in immigrants. In the parents, underweight was particularly high in Italian and Other mothers. African parents had high rates of overweight and obesity and a low educational level. The most common profession was worker for the fathers and housewife for the mothers, with the exception of Italians in which clerical work prevailed. Multiple linear regression analysis showed that the BMI of children was closely related to the BMI of the parents and the birth weight. Hence, these are the most informative parameters in preventing obesity.

    Thyroid stimulating hormone (TSH) concentrations in the high normal range are common in children with overweight and obesity, and associated with increased cardiovascular disease risk. Prior studies aiming at unravelling the mechanisms underlying these high TSH concentrations mainly focused on factors promoting thyrotropin releasing hormone (TRH) production as a cause for high TSH concentrations. However, it is unknown whether TSH release of the pituitary in response to TRH is affected in children with overweight and obesity. Here we describe TSH release of the pituitary in response to exogenous TRH in 73 euthyroid children (39% males) with overweight or (morbid) obesity. Baseline TSH concentrations (0.9–5.5 mU/L) were not associated with BMI z score, whereas these concentrations were positively associated with TSH concentrations 20 minutes after TRH administration (r2 = 0.484, p < 0.001) and the TSH incremental area under the curve during the TRH stimulation test (r2 = 0.307, p < 0.001). These results suggest that pituitary TSH release in response to TRH stimulation might be an important factor contributing to high normal serum TSH concentrations, which is a regular finding in children with overweight and obesity. The clinical significance and the intermediate factors contributing to pituitary TSH release need to be elucidated in future studies. PMID:27485208

    This article studies two pathways in which selection into different types of child care settings may affect likelihood of childhood obesity. Frequency of intake of high energy-dense and low energy-dense food items may vary across care settings, affecting weight outcomes. We find that increased use of paid and regulated care settings, such as center care and Head Start, is associated with higher consumption of fruits and vegetables. Among children from single-mother households, the probability of obesity increases by 15 percentage point with an increase in intake of soft drinks from four to six times a week to daily consumption and by 25 percentage point with an increase in intake of fast food from one to three times a week to four to six times a week. Among children from two-parent households, eating vegetables one additional time a day is associated with 10 percentage point decreased probability of obesity, while one additional drink of juice a day is associated with 10 percentage point increased probability of obesity. Second, variation across care types could be manifested through differences in the structure of the physical environment not captured by differences in food intake alone. This type of effect is found to be marginal and is statistically significant among children from two-parent households only. Data are used from the Early Childhood Longitudinal Study - Birth Cohort surveys (N=10,700; years=2001-2008). Children's age ranged from four to six years in the sample.

    Obstructive sleep apnoea (OSA), common in children with obesity, is associated with cardiovascular morbidity. Autonomic dysfunction has been suggested to be a key player in the development of these complications. We investigated the relationship between obesity, OSA and sympathetic activity in children. 191 children with obesity were included and distributed into two groups: 131 controls and 60 with OSA. Beat-to-beat RR interval data were extracted from polysomnography for heart rate variability analysis. Urinary free cortisol levels were determined. Urinary free cortisol did not differ between groups and was not associated with OSA, independent of the level of obesity. Differences in heart rate variability measures were found: mean RR interval decreased with OSA, while low/high-frequency band ratio and mean heart rate increased with OSA. Heart rate variability measures correlated with OSA, independent of obesity parameters and age: oxygen desaturation index correlated with mean heart rate (r=0.19, p=0.009) and mean RR interval (r= −0.18, p=0.02), while high-frequency bands and low/high-frequency band ratio correlated with arterial oxygen saturation measured by pulse oximetry (SpO2) (r= −0.20, p=0.008 and r= −0.16, p=0.04) and SpO2 nadir (r=0.23, p=0.003 and r= −0.19, p=0.02). These results suggest that sympathetic heart activity is increased in children with obesity and OSA. Measures of hypoxia were related to increased sympathetic tone, suggesting that intermittent hypoxia is involved in autonomic dysfunction. PMID:27999786

    Obesity is a strong cardiometabolic (CM) risk factor in children. We tested potential CM risk in obese/overweight children and the effect of an intensive lifestyle intervention using newer CM markers: atherogenic index of plasma AIP [Log(TG/HDL-C)], apoB/apoAI ratio and a marker of insulin resistance HOMA-IR. The participants (194 girls, 115 boys, average age 13) were enrolled in an intensive, one-month, inpatient weight reduction program. The program consisted of individualised dietary changes and the exercise program comprised aerobic and resistance training. Anthropometrical and biochemical parameters in plasma and CM risk biomarkers - (AIP, apoB/apoAI ratio and HOMA-IR) were examined before and after the intervention. AIP and HOMA-IR significantly correlated with BMI while apoB/apoAI ratio did not. Only AIP and HOMA-IR showed systematic increases according to the level of obesity by BMI quartiles. Lifestyle intervention significantly improved anthropometrical and biochemical values and the biomarkers too. The response of lipid parameters to the intervention was considerably higher in boys than in girls. The children were stratified into three risk categories according to AIP, where 13.8 % of boys and 5.3 % of girls fell into high risk category. The monitored biomarkers may complement each other in the prognosis of CM risk. AIP was strongly related to obesity and to lipid and glycid metabolism, while the relationship of the apoB/apoAI ratio to obesity and glycid metabolism was not significant. The obese children benefited from the intensive lifestyle intervention which improved the anthropometrical and biochemical parameters and CM risk biomarkers.

    Abstract Rationale: Urethral hemangiomas commonly occur in men or elderly women. We presented a rare case of urethral hemangioma in a prepubertal female patient. Patients concerns: An 8-year-old girl had the complaints of bloody staining of clothing, a foul perineal odor, and urethral pain. She was brought to our genitourinary outpatient department for survey and a single, 1-cm compressible reddish nodule at the 10-2 o’clock position in the distal urethra was found. Diagnoses: Urethral hemangioma in a prepubertal girl was diagnosed after excision of the urethral nodule. Interventions: Excision with 8 “stay” sutures in the protruding urethral mucosa was performed. Outcomes: Normal micturition without symptom recurrence was noted at the 3-month follow-up. Lessons: Urethral hemangioma is also found in prepubertal female patient. Increased physician awareness and early recognition of a urethral hemangioma can avoid unnecessary examinations and patient anxiety. The procedure of excision with 8 “stay” sutures in the protruding urethral mucosa facilitates mobilization from the distal urethra and provides a good surgical view of abnormal proliferative blood vessels. Therefore, the lesion can be removed as clean as possible. PMID:28353601

    2016-01-01

    Objective Short sleep duration is recognized as a significant risk factor in childhood obesity; however, the question as to how sleep contributes to the development of obesity remains largely unknown. The majority of pediatric studies have relied on sleep duration as the exclusive measure of sleep; this insular approach may be misleading given that sleep is a dynamic multidimensional construct beyond sleep duration, including sleep disturbances and patterns. While these sleep dimensions partly overlap, it is necessary to determine their independent relation with obesity, which in turn, may inform a more comprehensive understanding of putative pathophysiological mechanisms linking sleep and obesity. The aim of the present study was to investigate whether sleep dimensions including sleep duration, disturbances, and patterns were individually associated with obesity, independent of multiple covariates. The second objective was to examine whether sleep disturbances and patterns were independently associated with obesity, after adjusting for sleep duration. Method Participants included 240 healthy children and adolescents (Mage=12.60, SD=1.98; 45.8% females). Anthropometric measures included measured waist and hip circumference, body mass index Z-score and percent body fat. Subjective sleep measures included sleep duration, sleep disturbances, sleep quality, and sleep patterns from youth- and parental-report. Results Youth with larger adiposity and body composition measures reported poorer sleep quality (βavg=−0.14, p<.01), more sleep disturbances (βavg=0.13, p<.05), and showed a delayed sleep phase pattern (βavg=0.15, p<.05), independent of age, sex, pubertal status, physical activity, screen time, socioeconomic status, and sleep duration. Shorter sleep duration was significantly associated with obesity; however, this link was attenuated after adjustment of covariates. Conclusions Results suggest sleep measures beyond duration may more precisely capture influences

    Background Studies that evaluate both body composition and metabolic syndrome (MeS) risk in prepubertal children with premature adrenarche (PA) are limited. Methods Fifty-eight prepubertal children (5-9 years, 33F and 25M), with PA(n=30) and controls (n=28) were evaluated for the presence of MeS as defined by age-modified NCEP ATP III criteria. A subset had dual-energy x-ray absorptiometry and bone markers (n=23/58) to evaluate the effect of hyperandrogenism on metabolic abnormalities and body composition. Results There was no difference in prevalence of MeS between PA and controls(p=0.138). Children with MeS were obese with increased WC and decreased HDL levels. Androgens were not associated with having more than one criteria for MeS (p=0.08), but were associated with triglycerides and WC (p=0.029, p=0.041). Lean mass was greater in PA (p=0.039) and androgens correlated with BMD(p=0.029) and total body fat(p=0.008). Subjects with higher percent body fat were more likely to have more than one MeS risk factor(p=0.005). Conclusions MeS was seen only in obese subjects whether or not they had PA. Thus, it appears that obesity drives metabolic risk in the prepubertal population, rather than PA. Our findings are important in determining how the prepubertal patient with PA should be evaluated for metabolic risk. PMID:26513727

    Abstract Objective: To analyze the associations between socioeconomic status (SES) indicators and physical activity and overweight/obesity in children. Methods: 485 children wore accelerometers for 7 days. Variables included time in sedentary behavior and moderate-to-vigorous physical activity (MVPA), and steps/day. Children were further categorized as meeting or not meeting guidelines of ≥60min/day MVPA and ≥12,000 steps/day. Body mass index (BMI) and body fat percentage (BF%) were measured using bioelectrical impedance. Overweight/obesity was defined as BMI >+1 SD and BF% ≥85th percentile. Parents answered questionnaires that questioned total annual household income, parental education level, parental employment status and automobile ownership. Results: Children averaged 59.5min/day in MVPA (44.1% met MVPA guidelines), and 9639 steps/day (18.4% met steps/day guidelines). 45.4% and 33% were overweight/obese classified by BMI and BF% respectively. Higher relative total annual household income level (Odds Ratio 0.31; 95% confidence interval=0.15-0.65), and relatively higher maternal (OR=0.38; 95%CI=0.20-0.72) and paternal (OR=0.36; 95%CI=0.17-0.75) education levels were associated with lower odds of children meeting MVPA guidelines. Household automobile ownership was associated with lower odds of children meeting MVPA (OR=0.48; 95%CI=0.31-0.75) and steps/day guidelines (OR=0.44; 95%CI=0.26-0.74). Conclusions: SES indicators were not associated with overweight/obesity, but higher SES was associated with lower odds of children meeting MVPA guidelines. PMID:26975562

    Vitamin D insufficiency/deficiency is common among non-white children; however, little is known about the prevalence of vitamin D insufficiency/deficiency in non-white obese children living in the Netherlands. Therefore, a retrospective analysis was performed on data from multi-ethnic Dutch children and adolescents 6–18 years who visited the obesity outpatient clinic in 2012–2013. We performed anthropometric measurements, oral glucose tolerance test, and measured 25(OH)D and lipid levels. Vitamin D insufficiency was defined as 25(OH)D levels 37.5- <50 nmol/L and vitamin D deficiency as 25(OH)D <37.5 nmol/L. In total, data from 387 children were obtained (mean age 11.6 years, 41.1 % boys, 10.3 % Dutch native, 25.6 % Turkish, 24.5 % Moroccan, 7.5 % African Surinamese, and 7.0 % West African). The median 25(OH)D level was 34 (range 12–105) nmol/L. In total, 17.8 % were vitamin D sufficient, 24.5 % with vitamin D insufficiency, and 57.6 % with vitamin D deficiency. Obese ethnic children showed the highest (87.5 %) and normal weight white children showed the lowest (20.0 %) prevalence of vitamin D insufficiency/deficiency . Conclusion: Vitamin D insufficiency and deficiency is extremely prevalent in treatment-seeking obese ethnic children. However, there was no evidence of an effect of vitamin D status on various components of the metabolic syndrome in our cohort.

    High blood pressure (BP) and overweight/obesity are increasingly prevalent in children. We examined the associations of excess weight indicators including neck circumference (NC) and body mass index (BMI) with high BP in children. We hypothesized that high NC is associated with elevated BP. We utilized cross-sectional anthropometric and BP data on 1058 children aged 6-18 years. Patients were classified into weight and NC categories according to published guidelines. Prehypertension was defined as systolic or diastolic BP levels between 90th and 95th percentile for gender, age and height. Hypertension signifies systolic and/or diastolic BP levels ≥ 95th percentile for age, gender and height. The prevalence of elevated BP was 29.2% (prehypertension=10.1%, hypertension=19.1%). The prevalence of overweight and obesity was 19.0 and 18.7%, respectively. Rates of wide NC increased progressively with BMI categories by 8.8, 29.4 and 68.7% among normal weight, overweight and obese children, respectively. Within each BMI category, the unadjusted odds ratio for elevated BP was significantly higher in children with wide NC than those with normal NC (normal weight OR=1.78 (1.0-3.1), P=0.04); overweight OR=2.74 (1.5-5.2), P=0.001); obese OR=2.44 (1.3-4.6), P=0.006)). Increasing NC and BMI are associated with elevated BP in children. Joint presence of wide NC and high BMI is associated with significantly high rates of elevated BP. NC measurement may be a helpful tool to detect the presence of elevated BP in children.

    Whether nonalcoholic fatty liver disease (NAFLD) is related to vitamin D and bone health in obese children is unknown. The aim of this study was to evaluate vitamin D status and bone mineral density (BMD) in obese children according to their condition within the NAFLD spectrum. Anthropometric data, laboratory tests, and abdominal ultrasonography were obtained from 94 obese children. The subjects were divided into three groups according to NAFLD spectrum: normal liver, simple steatosis, and nonalcoholic steatohepatitis (NASH). Although there were no differences in vitamin D levels between the three groups, these groups showed significant differences in highly sensitive C-reactive protein (P=0.044), homeostasis model assessment of insulin resistance (HOMA-IR) (P=0.02), hepatic fibrosis scores (P<0.05), and trunk fat percentage (P=0.025). Although there were significant differences in BMDs, the age-matched BMD z-scores were not significantly different between the three groups. Serum vitamin D levels were negatively correlated with age (r=-0.368, P=0.023), serum uric acid levels (r=-0.371, P=0.022), fibrosis 4 (FIB4) (r=-0.406, P=0.011), and HOMA-IR (r=-0.530, P=0.001) in obese children with NASH. Multiple regression analysis for vitamin D in the NASH group revealed age and HOMA-IR as significant factors. In conclusion, inflammatory markers, hepatic fibrosis scores, trunk fat, and insulin resistance may reflect the spectrum of NAFLD in obese children, whereas vitamin D levels and BMD may not. In patients with NASH, however, low serum vitamin D is associated with hepatic fibrosis and insulin resistance, but not with bone health status. PMID:26713058

    Background: Obesity is a global epidemic and its morbidities such as metabolic syndrome, insulin resistance, and fatty liver leads to a spectrum of psycho-social and medical consequences. Objectives: The objective of this study was to investigate the prevalence of fatty liver in obese Iranian children and its' association with metabolic syndrome and insulin resistance. Patients and Methods: 102 obese Iranian children, referred to pediatric clinics from March 2011 to March 2012, were enrolled in this cross-sectional study. All the patients were visited by a pediatric endocrinologist, a pediatric gastroenterologist and an expert radiologist in the evaluation of fatty liver grading. Results: The grade of fatty liver was higher in older children (P = 0.001). It was also more in taller and heavier children (P = 0.000). The more the BMI was, the more the fatty liver grade was (P = 0.002). Severity of fatty liver according to liver sonography in patient had a positive relationship with waist circumference, hip circumference, serum TG, serum FBS, serum fasting insulin, serum ALT, systolic blood pressure and HOMA index and had a negative correlation with the level of alkaline phosphatase. Severity of fatty liver also had a close relationship with the presence of acanthosis nigricans and HOMA index. Conclusions: Prevalence of fatty liver is high in our obese children. It was associated with criteria of metabolic syndrome and insulin resistance, so visceral fat may participate in the pathogenesis of the metabolic syndrome or merely serve as a marker of increased risk for the metabolic complications of obesity.

    Obesity in Chilean children has increased markedly over the past decades. School-based obesity prevention interventions have been launched by the Ministry of Health and academic groups to tackle this condition. We summarize the main characteristics of the interventions that we have conducted and reflect on the lessons learned. Since 2002, we conducted 1 pilot study, a 2-y controlled intervention including 6- to 12–y-old children (Casablanca), another pilot study, and a 2-y controlled intervention including teachers and their 4- to 9–y-old students (Macul). Both interventions consisted of training teachers to deliver contents on healthy eating, increasing physical education classes, and, additionally in Macul, teachers participated in a wellness program. BMI Z-score and obesity prevalence were compared among children in intervention and control schools by year and among students of intervention and control teachers. In the Casablanca study, the impact was greatest on the younger children during the first school year when the study received the full funding that was required. In Macul, although intervention teachers exhibited improvements in anthropometry and blood measures, the impact on the children was not related to their results. The main lessons learned from these experiences are random allocation of schools, although methodologically desirable, is not always possible; participation of parents is very limited; obesity is not recognized as a problem; and increasing physical activity and implementing training programs for teachers is difficult due to an inflexible curriculum and lack of teachers’ time. Unless these barriers are overcome, obesity prevention programs will not produce positive and lasting outcomes. PMID:22798002

    Introduction: Obesity in children is assumed to serve as a major risk factor in pediatric obstructive sleep apnea syndrome (OSAS). However, the prevalence of OSAS in otherwise healthy obese children from the community is unknown. Aim: To determine the prevalence of OSAS in obese children identified and recruited from primary care centers. Methods: A cross-sectional, prospective, multicenter study. Spanish children ages 3–14 y with a body mass index (BMI) greater than or equal to the 95th percentile for age and sex were randomly selected, and underwent medical history, snoring, and Pediatric Sleep Questionnaire (PSQ) assessments, as well as physical examination, nasopharyngoscopy, and nocturnal polysomnography (NPSG) recordings. Results: Two hundred forty-eight children (54.4% males) with mean age of 10.8 ± 2.6 y were studied with a BMI of 28.0 ± 4.7 kg/m2 corresponding to 96.8 ± 0.6 percentile when adjusted for age and sex. The mean respiratory disturbance index (RDI), obstructive RDI (ORDI), and obstructive apnea-hypopnea index (OAHI) were 5.58 ± 9.90, 5.06 ± 9.57, and 3.39 ± 8.78/h total sleep time (TST), respectively. Using ≥ 3/h TST as the cutoff for the presence of OSAS, the prevalence of OSAS ranged from 21.5% to 39.5% depending on whether OAHI, ORDI, or RDI were used. Conclusions: The prevalence of obstructive sleep apnea syndrome (OSAS) in obese children from the general population is high. Obese children should be screened for the presence of OSAS.

Dazing on the results it is suggested to include in cardiovascular syndrome in children with obesity together with arterial hypertension syndrome of vegetative (autonomic) dysfunction, manifesting by disturbance of heart rate variability, endothelial dysfunction as well as systolic-diastolic dysfunction of the left ventricle. Degree of severity of impairment of cardiovascular system in children and adolescents with obesity depends on the level of insulin resistance.

    Children with developmental coordination disorder (DCD) find themselves less competent than typically developing children with regard to their physical abilities and often experience failure. They are therefore likely to avoid physical activity. Physical inactivity is considered an important risk factor for developing overweight and obesity. The aim of this study is to assess the association between DCD and overweight and obesity in children and whether this association is influenced by age and/or gender. Six electronic databases were systematically searched. Titles and abstracts were screened for relevance. Remaining studies were subjected to full paper review. The quality of the included articles was assessed and relevant data were extracted for comparison. The search yielded 273 results. Twenty-one studies, based on 10 cohorts, were included. Participants' ages ranged from 4 to 14 years. In all cohorts, children with DCD had higher body mass index scores, larger waist circumference and greater percentage body fat compared with controls. Seven studies assessed the effect of gender and four studies provided information on the effect of age. Children with DCD seem to be at greater risk for overweight and obesity. This risk may be higher for boys and seems to increase with age and with the severity of motor impairment.

    The frequency of overweight and obesity among North American Indian children and youth exceeds that of other ethnic groups in the United States. This observation is based on studies using body mass index as the primary measure of overweight and obesity. In the mid-20th century, there were regional differences among North American Indian groups in sub-adults' size and shape and only a few Southwestern groups were characterized by high rates of overweight and obesity. In most populations, the high prevalence of overweight and obesity developed in the last decades of the 20th century. Childhood obesity may begin early in life as many studies report higher birth weights and greater weight-for-height in the preschool years. Contributing factors include higher maternal weights, a nutritional transition from locally caught or raised foods to store bought items, psychosocial stress associated with threats to cultural identity and national sovereignty, and exposure to obesogenic pollutants, all associated to some degree with poverty. Obesity is part of the profile of poor health among Native Americans in the US and Canada, and contributes to woefully high rates of diabetes, cardiovascular disease, and early mortality. Interventions that are culturally appropriate are needed to reduce weights at all points in the lifespan.

    The prevalence of childhood obesity is increasing in many countries and confers risks for early type 2 diabetes, cardiovascular disease and metabolic syndrome. In the presence of potent 'obesogenic' environments not all children become obese, indicating the presence of susceptibility and resistance. Taking an energy balance approach, susceptibility could be mediated through a failure of appetite regulation leading to increased energy intake or via diminished energy expenditure. Evidence shows that heritability estimates for BMI and body fat are paralleled by similar coefficients for energy intake and preferences for dietary fat. Twin studies implicate weak satiety and enhanced food responsiveness as factors determining an increase in BMI. Single gene mutations, for example in the leptin receptor gene, that lead to extreme obesity appear to operate through appetite regulating mechanisms and the phenotypic response involves overconsumption and a failure to inhibit eating. Investigations of robustly characterized common gene variants of fat mass and obesity associated (FTO), peroxisome proliferator-activated receptor (PPARG) and melanocortin 4 receptor (MC4R) which contribute to variance in BMI also influence the variance in appetite factors such as measured energy intake, satiety responsiveness and the intake of palatable energy-dense food. A review of the evidence suggests that susceptibility to childhood obesity involving specific allelic variants of certain genes is mediated primarily through food consumption (appetite regulation) rather than through a decrease in activity-related energy expenditure. This conclusion has implications for early detection of susceptibility, and for prevention and management of childhood obesity.

    Obesity presents major challenges for public health and the evidence is strong. Lessons from tobacco control indicate a need for changing the policy and environments to make healthy choices easier and to create more opportunities for children to achieve healthy weights. In April 2011, the Alberta Policy Coalition for Chronic Disease Prevention convened a consensus conference on environmental determinants of obesity such as marketing of unhealthy foods and beverages to children. We examine the political environment, evidence, issues, and challenges of placing restrictions on marketing of unhealthy foods and beverages within Canada. We recommend a national regulatory system prohibiting commercial marketing of foods and beverages to children and suggest that effective regulations must set minimum standards, monitor compliance, and enact penalties for non-compliance.

    This study aimed to identify the actual and perceived features of neighborhood environments linked to health behaviors and obesity status in vulnerable children by using geographic information systems, walking surveys, and focus group interviews. The participants were 126 children registered at community child centers and 10 mothers of study participants. Increased availability of fast food outlets and convenience stores was significantly and positively associated with fast food and sugar-sweetened beverage consumption and inversely with physical activity. Reduced availability of physical activity outlets was significantly and positively associated with sedentary behaviors. Mothers' perceptions of their neighborhoods fell into three content categories: (a) changed to be unfriendly for children, (b) adapted to fast food and convenience eating, and (c) confined to physically inactive living. Based on these findings, community-level environmental strategies for reducing unhealthy behaviors linked to neighborhood environments should be prioritized to prevent childhood obesity in vulnerable populations.

    The objective of this study was to analyze thoraco-abdominal kinematics in obese children in seated and supine positions during spontaneous quiet breathing. An observational study of pulmonary function and chest wall volume assessed by optoelectronic plethysmography was conducted on 35 children aged 8-12 years that were divided into 2 groups according to weight/height ratio percentiles: there were 18 obese children with percentiles greater than 95 and 17 normal weight children with percentiles of 5-85. Pulmonary function (forced expiratory volume in 1 s (FEV1); forced vital capacity (FVC); and FEV1/FVC ratio), ventilatory pattern, total and compartment chest wall volume variations, and thoraco-abdominal asynchronies were evaluated. Tidal volume was greater in seated position. Pulmonary and abdominal rib cage tidal volume and their percentage contribution to tidal volume were smaller in supine position in both obese and control children, while abdominal tidal volume and its percentage contribution was greater in the supine position only in obese children and not in controls. No statistically significant differences were found between obese and control children and between supine and seated positions regarding thoraco-abdominal asynchronies. We conclude that in obese children thoraco-abdominal kinematics is influenced by supine posture, with an increase of the abdominal and a decreased rib cage contribution to ventilation, suggesting that in this posture areas of hypoventilation can occur in the lung.

    The present study aimed to systematically review the literature about intima-media thickness (IMT), blood pressure (BP), and lipid profile (LP) in obese and non-obese children and adolescents. The search was carried out in electronic databases (PubMed, Bireme, and Elsevier ScienceDirect) between 2000-2010. The following keywords, in English, were used: "obesity", "adolescents", "atherosclerosis" and "child", using two combinations: obesity+child+atherosclerosis and obesity+adolescents+atherosclerosis. The electronic search resulted in 3,211 manuscripts. After analysis of the inclusion criteria, 13 papers were selected. Of these, two studies showed significant correlation between IMT and the variables BP, LDL, and triglycerides. In other studies, no significant correlations were found. There is a wide methodological variability across the studies. However, obese children and adolescents had higher values of IMT, BP, and LP.

    The non alcoholic fatty liver disease (NAFLD) manifests with liver damage and it is associated with obesity. The objective of this work was to detect the risk of obese school students of developing NAFLD, through an analytical, observational study, comparing their liver function with that of a control group, and its relationship with physical activity, dietary, biochemical and anthropometric variables. One hundred and sixty school students (ages 7-11) were evaluated according to their socio-economic status; nutritional status by the body mass index (BMI) and mid-upper arm fat area (MUAC) (Project Venezuela 1994); body fat percentage by anthropometry (% BF), waist circumference (WC); and metabolism by oral glucose tolerance, basal insulin and post-load glucose, total cholesterol (TC), cLDL, cVLDL, cHDL, triglycerides (TG), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), gamma glutamil transpeptidasa (GGTP) and albumin. Their diet was analyzed by the 24-hour recall and their physical activity by a clinical trial. Mean levels of GPT (p < 0.05), greater frequencies of elevated GOT and GPT (p < 0.05) and lower albumin levels (p < 0.05) were observed in 88 obese school students when compared to controls. The GPT correlated significantly with the BMI, MUAC, % BF, WC, basal insulin and post-load glucose, HOMA, cVLDL, cHDL and TG, while the GOT correlated with MUAC and the GGTP with MUAC, basal insulin, HOMA and cLDL. Albumin was negatively correlated with BMI, MUAC, % BF and WC. TGP reflected better the hepatic compromise of obesity. To assess the risk of NAFLD, the TGO/TGP values should be standardized according to age, gender and race.

    Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in children and adolescents in industrialized countries. Recent studies have demonstrated a prevalence rate of NAFLD in overweight and obese children and adolescents in Germany of up to 30%. The spectrum of NAFLD ranges from pure fatty infiltration (simple steatosis) to inflammation (steatohepatitis, synonymous NASH) to fibrosis and cirrhosis. Age, gender, ethnicity, insulin resistance, and sex steroids are implicated in the pathogenesis of NAFLD in childhood and adolescence. Moreover, NAFLD in the pediatric age group is associated with marked cardiovascular comorbidities. This review focuses on current data regarding epidemiology, pathophysiology, comorbidities, and treatment of NAFLD in children and adolescents.

    This paper investigates one explanation for the consistent observation of a strong, negative correlation in the United States between income and obesity among women, but not men. We argue that a key factor is the gendered expectation that mothers are responsible for feeding their children. When income is limited and households face food shortages, we predict that an enactment of these gendered norms places mothers at greater risk for obesity relative to child-free women and all men. We adopt an indirect approach to study these complex dynamics using data on men and women of childrearing age and who are household heads or partners in the 1999-2003 waves of the Panel Study of Income Dynamics (PSID). We find support for our prediction: Food insecure mothers are more likely than child-free men and women and food insecure fathers to be overweight or obese and to gain more weight over four years. The risks are greater for single mothers relative to mothers in married or cohabiting relationships. Supplemental models demonstrate that this pattern cannot be attributed to post-pregnancy biological changes that predispose mothers to weight gain or an evolutionary bias toward biological children. Further, results are unchanged with the inclusion of physical activity, smoking, drinking, receipt of food stamps, or Women, Infants and Children (WIC) nutritional program participation. Obesity, thus, offers a physical expression of the vulnerabilities that arise from the intersection of gendered childcare expectations and poverty.

    The study assessed the anthropometric status of 337 sub-Saharan African children aged between 3-12 years who migrated to Australia. These children were selected using a snowball sampling method stratified by age, gender and region of origin. The prevalence rates for overweight and obesity were 18.4% (95%CI: 14 - 23%) and 8.6% (95%CI: 6% -12%) respectively. The prevalence rates for the indicators of undernutrition were: wasting 4.3% (95%CI: 1.6%-9.1%), underweight 1.2% (95%CI: 0.3%-3.0%), and stunting 0.3 (95%CI: 0.0%-1.6%). Higher prevalence of overweight/obesity was associated with lower household income level, fewer siblings, lower birth weight, western African background, and single parent households (after controlling for demographic and socio-economic factors). Higher prevalence rates for underweight and wasting were associated with lower household income and shorter lengths of stay in Australia respectively. No effect was found for child's age, gender, parental education and occupation for both obesity and undernutrition indices. In conclusion, obesity and overweight are very prevalent in SSA migrant children and undernutrition, especially wasting, was also not uncommon in this target group.

    Purpose. Genome-wide association studies have found two obesity-related single-nucleotide polymorphisms (SNPs), rs17782313 near the melanocortin-4 receptor (MC4R) gene and rs6265 near the brain-derived neurotrophic factor (BDNF) gene, but the associations of both SNPs with other obesity-related traits are not fully described, especially in children. The aim of the present study is to investigate the associations between the SNPs and adiponectin that has a regulatory role in glucose and lipid metabolism. Methods. We examined the associations of the SNPs with adiponectin in Beijing Child and Adolescent Metabolic Syndrome (BCAMS) study. A total of 3503 children participated in the study. Results. The SNP rs6265 was significantly associated with adiponectin under an additive model (P = 0.02 and 0.024, resp.) after adjustment for age, gender, and BMI or obesity statuses. The SNP rs17782313 was significantly associated with low adiponectin under a recessive model. No statistical significance was found between the two SNPs and low adiponectin after correction for multiple testing. Conclusion. We demonstrate for the first time that the SNP rs17782313 near MC4R and the SNP rs6265 near BDNF are associated with adiponectin in Chinese children. These novel findings provide important evidence that adiponectin possibly mediates MC4R and BDNF involved in obesity.

    Often, researchers and clinicians approach the African-American community from a deficit model with African Americans viewed as having less desirable health practices and higher disease risk; however, in developing interventions for African Americans, it is important to keep in mind positive aspects of black culture as they relate to obesity. For example, the cultural acceptance of a larger body type and less negative views toward overweight individuals need not be viewed as problematic or abnormal. In fact, it could be argued that majority culture has a dysfunctional view of body image and obesity. The fact that whites are less likely to be overweight than African Americans may stem from a value system that places undue emphasis on thinness, youth, and external beauty and a culture that imbues women with shame about how they look and what they eat. Thus, rather than holding whites and majority culture as the ideal, it may be important to incorporate the positive elements of black culture regarding body image and food rather than attempting to shift their values toward those of European Americans. How best to achieve a reduction in obesity and its medical consequences, without inducing undesirable shifts in body image and attitudes toward food, is a formidable but important challenge.

    While neighborhood environments are increasingly recognized as important contributors to obesity risk, less has been reported on the socio-cultural aspects of neighborhoods that influence obesity development. This is especially true among immigrants, who may lack the necessary language skills to navigate their new living environments. In this study, we tested the hypothesis that young children of immigrants would be at lower obesity risk if they lived in neighborhoods where neighbors share the same language and culture. Using 2000 Census data and 2003-2009 data from the Special Supplemental Nutrition Program for Women, Infants and Children in Los Angeles County, we examined the relation between BMI z-scores in low-income children aged 2-5 years (N = 250,029) and the concentration of neighborhood residents who spoke the same language as the children's mothers. Using multi-level modeling and adjusting for child's gender and race/ethnicity, household education, neighborhood socioeconomic status, and year the child was examined, we found that percent of neighborhood residents who spoke the same language as the child's mother was negatively associated with BMI z-scores. This relation varied by child's race/ethnicity and mother's preferred language. The relation was linear and negative among children of English-speaking Hispanic mothers and Chinese-speaking mothers. However, for Hispanic children of Spanish-speaking mothers the relation was curvilinear, initially exhibiting a positive relation which reversed at higher neighborhood concentrations of Spanish-speaking residents. Our findings suggest that living in neighborhoods where residents share the same language may influence obesity-related behaviors (namely diet and physical activity) possibly through mechanisms involving social networks, support, and norms.

    Recent studies show an alarming increase in the rate of overweight / obesity among the infant - juvenile population. Obesity in childhood is associated with a significant number of complications, such as sleep apnea syndrome, insulin resistance and type 2 diabetes, hypertension, cardiovascular disease and some cancers. It is estimated that the prevalence of sleep apnea in children is 2-3% in the general population, while in obese adolescents, varies between 13% and 66%, according to various studies. It is associated with impairment of neurocognitive function, behavior, cardiovascular system, metabolic disorders and growth. Sleep apnea is a serious public health problem that increases when children and adolescents are overweight or obese. We hypothesize that aerobic endurance exercise can be an effective treatment for obesity and apnea at the same time. The aim of this study was to determine the influence of physical activity in children and adolescents with overweight / obesity in sleep apnea. An observational, descriptive, prospective, longitudinal study will be carried out in children with sleep apnea and obesity. The universe will be made up of 60 children and adolescents aged between 10 and 18 years, attending the endocrinology service for suffering of obesity in the Hospital Clinico San Cecilio of Granada during the period September 2012-September 2013. The smple will consist of children and adolescents that meet these characteristics and to whom their parents/tutors have authorized through the informed consent. Sleep apnea in children wil be measured by polysomnography and sleep quality questionnaire. There will also be a nutritional assessment by a food frequency questionnaire and an anthropometric assessment. Among the expected results are the lower overweight and obesity in children through the physical activity program. To reduce apnea and to improve sleep quality.

    The current article reviews several practical approaches to screening for obesity risk among children and youth, with an emphasis on the spectrum of physical activity. We encourage physicians to utilize evidence-based strategies (e.g., 5-2-1-0), implement motivational interviewing techniques, and focus on "crunch time" (i.e., the period of day after school and before bedtime) when gathering information about physical activity type and intensity. The insights gained are useful for evaluating obesity risk and establishing goals for lifestyle interventions. Characteristics of successful interventions with youth are also discussed and include goal-setting, self-monitoring, and pedometers.

    Background Prevalence of high blood pressure (BP) among American children has increased over the past two decades, due in part to increasing rates of obesity and excessive dietary salt intake. Objective We tested the hypotheses that the relationships among BP, salty taste sensitivity, and salt intake differ between normal-weight and overweight/obese children. Design In an observational study, sodium chloride (NaCl) and monosodium glutamate (MSG) taste detection thresholds were measured using the Monell two-alternative, forced-choice, paired-comparison tracking method. Weight and BP were measured, and salt intake was determined by 24-hour dietary recall. Participants/Setting Eight- to 14-year-olds (N=97; 52% overweight or obese) from the Philadelphia area completed anthropometrics and BP measurements; 97% completed one or both thresholds. Seventy-six percent provided valid dietary recall data. Testing was completed between December 2011 and August 2012. Main outcome measures NaCl and MSG detection thresholds, BP, and dietary salt intake. Statistical analyses Outcome measures were compared between normal-weight and overweight/obese children with t-tests. Relationships among outcome measures within groups were examined with Pearson correlations, and multiple regression analysis was used to examine the relationship between BP and thresholds, controlling for age, BMI-Z score, and dietary salt intake. Results Salt and MSG thresholds were positively correlated (r(71)=0.30, p=0.01) and did not differ between body-weight groups (p>0.20). Controlling for age, BMI-Z score, and salt intake, systolic BP was associated with NaCl thresholds among normal-weight children (p=0.01), but not among overweight/obese children. All children consumed excess salt (>8 g/day). Grain and meat products were the primary source of dietary sodium. Conclusions The apparent disruption in the relationship between salty taste response and BP among overweight/obese children suggests the relationship

    The first line of treatment of obstructive sleep apnoea syndrome (OSAS) in children consists of adenotonsillectomy (T&A). The aim of the present study was to evaluate treatment outcomes of OSAS among obese children recruited from the community.A cross-sectional, prospective, multicentre study of Spanish obese children aged 3-14 years, with four groups available for follow-up: group 1: non-OSAS with no treatment; group 2: dietary treatment; group 3: surgical treatment; and group 4: continuous positive airway pressure treatment.117 obese children (60 boys, 57 girls) with a mean age of 11.3±2.9 years completed the initial (T0) and follow-up (T1) assessments. Their mean body mass index (BMI) at T1 was 27.6±4.7 kg·m(-2), corresponding to a BMI Z-score of 1.34±0.59. Mean respiratory disturbance index (RDI) at follow-up was 3.3±3.9 events·h(-1). Among group 1 children, 21.2% had an RDI ≥3 events·h(-1) at T1, the latter being present in 50% of group 2, and 43.5% in group 3. In the binary logistic regression model, age emerged as a significant risk factor for residual OSAS (odds ratio 1.49, 95% confidence interval 1.01-2.23; p<0.05) in obese children surgically treated, and RDI at T0 as well as an increase in BMI emerged as significant risk factors for persistent OSAS in obese children with dietary treatment (OR 1.82, 95% CI 1.09-3.02 (p<0.03) and OR 8.71, 95% CI 1.24-61.17 (p=0.03)).Age, RDI at diagnosis and obesity are risk factors for relatively unfavourable OSAS treatment outcomes at follow-up.

    INTRODUCTION To investigate the association between abdominal obesity and metabolic syndrome (MetS) burden in a population-based sample of adolescents. METHODS We used the data from 421 adolescents who completed the follow-up examination in the Penn State Children Cohort study. Dual-energy x-ray absorptiometry (DXA) was used to assess abdominal obesity, as measured by android/gynoid fat ratio (A/G ratio), android/whole body fat proportion (A/W proportion), visceral (VAT) and subcutaneous fat (SAT) areas. Continuous metabolic syndrome score (cMetS), calculated as the sum of the age and sex-adjusted standardized residual (Z-score) of five established MetS components, was used to assess the MetS burden. Linear regression models were used to analyze the impact of DXA measures on cMetS and individual cMetS components. All models were adjusted for age, race, sex, and general obesity. RESULTS Abdominal obesity is significantly associated with increased cMetS. With 1 standard deviation (SD) increase in A/G ratio, A/W proportion, VAT area, and SAT area, cMetS increased by 1.34 (SE=0.17), 1.25 (SE=0.19), 1.67 (SE=0.17), and 1.84 (SE=0.20) units, respectively. At individual component level, strongest association was observed between abdominal obesity and insulin resistance than lipid-based or blood pressure-based components. VAT and SAT had a stronger impact on insulin resistance than android ratio-based DXA measurements. CONCLUSIONS Abdominal obesity is associated with higher MetS burden in adolescent population. The association between abdominal obesity and insulin resistance measure is the strongest, suggesting the key impact of abdominal obesity on insulin resistance in adolescents Mets burden.

    The purpose of this study was to investigate the effects of maternal gestational diabetes mellitus (GDM) and breast feeding on childhood overweight and obesity in a mainland Chinese population. The incidence of and factors associated with overweight and obesity were compared between children of mothers with (n=1068) and without (n=1756) GDM. The independent roles of the associated factors were examined by multiple logistic regression analysis. The incidence of overweight was higher (16.6 v. 12.6%, P=0.002) in the GDM group, but that of obesity was not different (10.7 v. 12.0%, P=0.315). At age 1-2 and 2-5 years, no difference in overweight (11.0 v. 12.0%, P=0.917, and 15.7 v. 14.6%, P=0.693, respectively) was found, while obesity (8.0 v. 13.6%, P=0.019, and 8.4 v. 13.4%, P=0.014, respectively) was less frequent in the GDM offspring. At age 5-10 years, increased overweight (22.2 v. 12.1%, P<0.001) and obesity (15.9 v. 9.0%, P=0.001) were found in the GDM group, which was associated with maternal obesity, being born large-for-gestational age, male gender and formula feeding. After adjusting for confounding factors, GDM remained an independent determinant of offspring overweight and obesity (aOR 2.28, 95% CI 1.61-3.22), suggesting that the effects of GDM were independent of breast feeding, as well as of maternal obesity and birth size.

    Physical activity may protect from the adverse effects of obesity. In obese children, an increased adherence and a decreased drop-out rate during exercise could be achieved with adapted activities. We studied a recreational 12-week controlled training program for sedentary obese children, including interactive video games. We enrolled 22 obese subjects (13.23±1.76 years) in an exercise program, implemented twice a week for a 12-week period. The program consisted of a combination of circuit-based aerobics, strength and resistance exercises; specifically soccer, rugby, volleyball and basketball and interactive video game exercises. Outcome measurements included body composition, metabolic profile and cardiorespiratory fitness. During the 12-week training program there was a significant decrease in body mass index (BMI) (p=0.002), SDS-BMI (p=0.003), waist circumference (p=0.004), waist circumference/height ratio (p=0.001),% fat mass (p=0.001), blood glucose (p=0.001), homeostasis model assessment for insulin resistance (HOMA-IR) (p=0.04), triglycerides (p=0.03) and systolic pressure (p=0.04) before and after exercise. Improvement in estimated maximum oxygen consumption (VO2max) (p<0.001) correlated with a decrease in fat mass (p=0.01), triglycerides (p=0.04) and insulin resistance (p=0.02). Exercise improved metabolic and cardiorespiratory fitness in obese children. Exercise training does not necessarily need to be vigorous, recreational programs are also effective and may encourage children to participate in physical activity and limit initial drop-out.

    Abstract Background: US Hispanic children experience a disproportionate burden of overweight and obesity. Comprehensive high-intensity behavioral programs have demonstrated effectiveness in improving weight status among obese children. However, there remains a need to develop more efficient interventions that are feasible in primary care and demonstrate effectiveness in Hispanic children. Methods: The pilot study used a two-group randomized design. Eligible overweight (BMI between the 85th and 94th percentile for age and gender) or obese (BMI ≥95th percentile) Hispanic children and their parents (N=118 child/parent dyads) were recruited from a rural pediatric clinic and randomized to: standard care (SC; n=61 dyads) or behavioral intervention (INT; n=57 dyads). The primary outcomes—weight, waist circumference, and zBMI—were measured at baseline, 2, 6, and 18 weeks. Multivariate logistic regression was used to examine the effect of INT on the likelihood of weight maintenance adjusting for potential confounding variables. Results: Significantly fewer INT children (68.5%) experienced weight gain, compared to SC children (89.7%; p=0.009). The same pattern was observed for waist circumference, where fewer INT children (44%) experienced an increase in waist circumference, compared to SC children (68.6%; p=0.02). Although a trend of improvement in favor of the INT was observed for zBMI, it was not significant. Conclusions: This study provides preliminary evidence for the feasibility of a primary-care–based approach to promoting weight maintenance among a high-risk population. PMID:25950140

    Objective There is a link between the symptoms of hyperactivity/inattention and overweight in children. Less is known about the factors which might influence this relationship, such as physical and sedentary activity levels or exercise self-efficacy. The aim of this study is to examine the associations between the symptoms of hyperactivity/inattention and risk factors for adult obesity in a sample of children with barriers to exercise. Design Children aged 9–11 years were recruited from 24 primary schools that participated in the Steps to Active Kids (STAK) physical activity intervention study. Study inclusion criteria were low exercise self-efficacy, teacher-rated overweight or asthma. Children with high levels of physical activity were excluded. Measures included parent and teacher-rated behavioural and emotional well-being using the Strengths and Difficulties Questionnaire, physical and sedentary activity levels, BMI (body mass index) and exercise self-efficacy. Results Of 424 participating children, 62% were girls and 39% were classified as overweight or obese. As compared with population norms, boys in this at-risk sample were more likely to receive an abnormal teacher-rated hyperactivity/inattention score (OR 1.48, 95% CI 1.01 to 2.17). Children with teacher-rated abnormal hyperactivity/inattention scores reported higher levels of sedentary activity (OR 1.13, 95% CI 1.02 to 1.17), but not physically active activity. The pattern of findings was similar for children with hyperactivity/inattention problems as rated by both parent and teacher (pervasive hyperactivity and impairment). Conclusions Although BMI was not directly related to hyperactivity/inattention, children with risk factors for adult obesity have more hyperactivity/inattention problems. In particular, hyperactivity/inattention is associated with higher levels of sedentary activity. Higher rates of pervasive hyperactivity and impairment were apparent in this at-risk group.

    Many daily routines and behaviors are related to the prevalence of obesity. This study investigated the association between routines and behaviors that act as protective factors related to lower prevalence of obesity in parents (BMI ≥ 30 kg/m(2)) and overweight in preschool children (BMI ≥ 85th percentile). Socio-demographic characteristics were assessed in relation to protective routines (PRs), and prevalence of obesity/overweight data from 337 preschool children and their parents. The two PRs assessed with parents included adequate sleep (≥7 h/night) and family mealtime routine (scoring higher than the median score). The four PRs assessed in children included adequate sleep (≥10 h/night), family mealtime routine, limiting screen-viewing time (≤2 h/day of TV, video, DVD), and not having a bedroom TV. Overall, 27.9% of parents were obese and 22.8% of children were overweight, and 39.8% of the parents had both parent PRs, and only 11.6% of children had all four child PRs. Results demonstrated that several demographic factors were significantly related to the use of PRs for parents and children. The lack of PRs was related to increased risk for overweight in children, but not for obesity in parents. However, in the adjusted models the overall cumulative benefits of using PRs was not significant in children either. In the multivariate adjusted logistic regression models, the only significant individual PR for children was adequate sleep. In a path analysis model, parent sleep was related to child sleep, which was in turn related to decreased obesity. Overall, findings suggest that parent and child PRs, especially sleep routines, within a family can be associated and may play an important role in the health outcomes of both parents and children. Understanding the mechanisms that influence how and when parents and children use these PRs may be promising for developing targeted family-based obesity-prevention efforts.

    Food addiction research in children is limited, and to date addictive-like eating behaviors within families have not been investigated. The aim of this study is to understand factors associated with addictive-like eating in children. The association between food addiction in children with obesity, parental food addiction, and parental feeding practices (i.e., restriction, pressure to eat, monitoring) was investigated. Parents/primary caregivers (aged≥18years) of children aged 5-12years, recruited and completed an online cross-sectional survey including demographics, the Yale Food Addiction Scale (YFAS), and the Child Feeding Questionnaire (CFQ). Parents, reporting on themselves and one of their children, were given a food addiction diagnosis and symptom score according to the YFAS predefined criteria. The total sample consisted of 150 parents/primary caregivers (48% male) and 150 children (51% male). Food addiction was found to be 12.0% in parents and 22.7% in children. In children, food addiction was significantly associated with higher child BMI z-scores. Children with higher food addiction symptoms had parents with higher food addiction scores. Parents of FA children reported significantly higher levels of Restriction and Pressure to eat feeding practices, but not Monitoring. Children with elevated YFAS-C scores may be at greater risk for eating-related issues.

    Few studies have examined the association between dietary sugar intake and obesity in Asian children and adolescents. We evaluated the association of dietary sugar intake and its food source with obesity in Korean children and adolescents. In this cross-sectional analysis, data were obtained from five studies conducted between 2002 and 2011. The study included 2599 children and adolescents who had completed more than three days of dietary records and had anthropometric data. Total sugar intake was higher in girls than in boys (54.3 g for girls and 46.6 g for boys, p < 0.0001). Sugar intake from milk and fruits was inversely associated with overweight or obesity in girls only (OR for overweight, 0.52; 95% CI, 0.32-0.84; p for trend = 0.0246 and OR for obesity, 0.42; 95% CI, 0.23-0.79; p for trend = 0.0113). Sugar-sweetened beverage (SSB) consumption was not associated with obesity in girls, while boys had lower odds ratios for obesity (OR for obesity, 0.52; 95% CI, 0.26-1.05; p for trend = 0.0310). These results suggest that total sugars and SSB intake in Asian children and adolescents remains relatively low and sugar intake from milk and fruits is associated with a decreased risk of overweight or obesity, especially in girls.

    Obesity during childhood is a dominant risk factor for noncommunicable diseases (NCDs), and is itself considered a disease that needs to be treated. Recently, the growth in childhood obesity in Korea has become stagnant; however, two in every ten children are still overweight. In addition, 60% or more of overweight children have at least one metabolic syndrome risk factor. Thus, childhood obesity should be controlled through lifestyle modification. This paper reviews studies of the modifiable risk factors of obesity in Korean children. According to the life-course approach, preschool-aged children (<5 years) are influenced by their parents rather than individual habits because they are under mostly parental care. Elementary school-aged children (6 to 11 years) are affected by overlapping individual and parental effects. This may mean that the establishment of individual behavior patterns begins during this period. The conditions of poor eating habits such as skipping meals, eating out, and high fat intake, along with low physical activity, facilitate increased obesity among adolescents (12 to 18 years). Notably, adolescent girls show high rates of both underweight and obesity, which may lead to the development of NCDs in their offspring. Therefore, the problem of NCDs is no longer limited to adults, but is also prevalent among children. In addition, early intervention offers cost-effective opportunities for preventing NCDs. Thus, children need primary consideration, adequate monitoring, diagnosis, and treatment to reduce the burden of NCDs later in adulthood. PMID:23946875

    2013-01-01

    Background Childhood obesity is a growing health concern known to adversely affect quality of life in children and adolescents. The Patient Reported Outcomes Measurement Information System (PROMIS) pediatric measures were developed to capture child self-reports across a variety of health conditions experienced by children and adolescents. The purpose of this study is to begin the process of validation of the PROMIS pediatric measures in children and adolescents affected by obesity. Methods The pediatric PROMIS instruments were administered to 138 children and adolescents in a cross-sectional study of patient reported outcomes in children aged 8–17 years with age-adjusted body mass index (BMI) greater than the 85th percentile in a design to establish known-group validity. The children completed the depressive symptoms, anxiety, anger, peer relationships, pain interference, fatigue, upper extremity, and mobility PROMIS domains utilizing a computer interface. PROMIS domains and individual items were administered in random order and included a total of 95 items. Patient responses were compared between patients with BMI 85 to < 99th percentile versus ≥ 99th percentile. Results 136 participants were recruited and had all necessary clinical data for analysis. Of the 136 participants, 5% ended the survey early resulting in missing domain scores at the end of survey administration. In multivariate analysis, patients with BMI ≥ 99th percentile had worse scores for depressive symptoms, anger, fatigue, and mobility (p < 0.05). Parent-reported exercise was associated with better scores for depressive symptoms, anxiety, and fatigue (p < 0.05). Conclusions Children and adolescents ranging from overweight to severely obese can complete multiple PROMIS pediatric measures using a computer interface in the outpatient setting. In the 5% with missing domain scores, the missing scores were consistently found in the domains administered last, suggesting the

    Obesity in adulthood is combined with vascular endothelial cell and platelet activation. In this study we evaluated whether or not such activation is already present in obese children. Forty obese (10.3 +/- 2.5 yr) and 40 nonobese (10.3 +/- 2.3 yr) children were studied. Circulating levels of soluble (s) intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin, as indices of vascular endothelial cell activation, were assessed in both groups. Plasma concentrations of sP-selectin and sCD40 ligand, as indices of platelet activation, were also measured. Circulating levels of highly sensitive C-reactive protein (hs-CRP) and the lipid peroxidation product 8-iso-prostaglandin (PG)F(2alpha) were evaluated because of their ability to promote vascular endothelial cell and platelet activation. Circulating levels of all of the assessed markers were higher in obese than in nonobese children (sICAM-1, +38.8 +/- 13.3%; sVCAM-1, +26.5 +/- 13.7%; sE-selectin, +31.3 +/- 17.3%; sP-selectin, +31.7 +/- 16.9%; sCD40 ligand, +36.9 +/- 22.1%; total 8-iso-PGF(2alpha), +24.0 +/- 20.2%; hs-CRP, +76.6 +/- 12.9%; P < 0.0001). Significant correlations (P < 0.004) between plasma total 8-iso-PGF(2alpha) levels and circulating sICAM-1 (r = 0.485), sVCAM-1 (r = 0.506), sP-selectin (r = 0.449), sCD40 ligand (r = 0.498), and hs-CRP (r = 0.520) concentrations were found in obese children. In conclusion, an early activation of vascular endothelial cells and platelets was present in obese children. Increased lipid peroxidation was also present in these children and likely contributed to the observed proinflammatory phenotype.

    Background: Considering the increasing trend of obesity, especially in developing countries such as Iran, and the role of inflammatory factors and insulin resistance (IR) in the occurrence of obesity-related complications as well as the safety of some agents such as folic acid and metformin, this clinical trial was designed to investigate the effect of metformin and folic acid on inflammatory factors and IR among obese children. Materials and Methods: In this randomized, double-blind, controlled clinical trial study, sixty obese children aged 6–12 years were enrolled. Selected obese children were randomly allocated in two interventional (1 mg/daily folic acid or 1000 mg metformin for 8 weeks) groups. Biochemical measurements including homeostasis model assessment of IR (HOMA-IR), homocysteine (Hcy), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8) were measured between and within the groups before and after trial. Results: In each group, thirty obese children were studied. The groups were age- and sex-matched. After folic acid and metformin administration, mean of Hcy, HOMA-IR, TNF-α, and IL-8 decreased significantly (P < 0.05). IL-6 decreased significantly after folic acid use (P < 0.05). Conclusion: The findings of this trial indicated that both metformin and folic acid could decrease IR and level of Hcy in obese children and adolescents. The effectiveness of metformin on IR was more significant than folic acid. Regarding the effectiveness of the two studied agents on inflammatory factors, it is suggested that the role of folic acid was superior to metformin. It is suggested that metformin is a proper agent for obese children with IR and folic acid is an appropriate supplement for obese children with increased inflammatory factors. PMID:27904616

    Despite the fact that past research identified childhood obesity as an antecedent of eating disorders, not all obese children further develop this pathology. With this regard, our first purpose was to isolate which characteristics differentiate overweight children who have an eating disorder from those who have not. Second, considering that there is little evidence collected in Latin American countries, we provided overweight children data from an Argentinean sample. Specifically, we investigated if weight-teasing, perfectionism, disturbed eating attitudes and behaviors, and body image dissatisfaction are related to the occurrence of an eating disorder in 100 school-aged overweight/obese children (37 girls and 63 boys; mean age 10.85, SD 0.88). Participants completed self-report instruments and were interviewed between 1 and 2 months later to confirm the presence of eating disorders. Seventeen percent participants confirmed to have an eating disorder. Further, the multivariate logistic analysis revealed that perfectionism (Exp β = 1.19) and disturbed eating attitudes and behaviors (Exp β = 4.78) were jointly associated with the presence of an eating disorder. These results were maintained even when the overall model was adjusted for covariates such as age, gender, body mass index, and school type. Weight-teasing and body image dissatisfaction did not contribute to the multivariate model. Prevalence rates of ED and model findings were discussed.

    The ToyBox intervention was developed using an evidence-based approach, using the findings of four reviews. These reviews included three critical and narrative reviews of educational strategies and psychological approaches explaining young children's acquisition and formation of energy-balance related behaviours, and the management of these behaviours, and also a systematic review of behavioural models underpinning school-based interventions in preschool and school settings for the prevention of obesity in children aged 4-6 years. This paper summarises and translates the findings from these reviews into practical evidence based recommendations for researchers and policy-makers to consider when developing and implementing interventions for the prevention of overweight and obesity in young (aged 4-6 years) children. The recommendations focus on two behaviours, physical activity and sedentary behaviour, and healthy eating, and include general recommendations, intervention approaches, interventions content, and simple messages. The review also briefly examines the role that the commercial sector plays in hindering or facilitating attempts to create healthy food environments for children. This paper also recognises that childhood obesity is not an issue for the education sector alone; it needs to be tackled at a multi sectoral level, recognizing the particularly important role of local governments, nongovernment organizations and the media.

    The prevalence of overweight and obesity is increasing in children and adolescents worldwide raising the question on the approach to this condition because of the potential morbidity, mortality, and economic tolls. Dietetic and behavioral treatments alone have only limited success; consequently, discussion on strategies for treating childhood and adolescent obesity has been promoted. Considering that our knowledge on the physiological systems regulating food intake and body weight is considerably increased, many studies have underlined the scientific and clinical relevance of potential treatments based on management of peripheral or central neuropeptides signals by drugs. In this paper, we analyze the data on the currently approved obesity pharmacological treatment suggesting the new potential drugs. PMID:21197151

    The aims were to examine the association of sleep patterns with being overweight or obese and to analyze the association of cardiorespiratory fitness (CRF) with sleep patterns in children. The study involved 395 schoolchildren (12-13 years old). Sleep patterns were assessed with the Sleep Self-Report (SSR) questionnaire, grouped into four subscales: sleep quality, sleep-related anxiety, bedtime refusal, and sleep routines. CRF was predicted by the 20-m shuttle-run test. Logistic regression models showed that sleep-related anxiety problems predicted being overweight or obese in both sexes, and sleep quality problems predicted being overweight or obese in girls. Also, girls who had better CRF levels were less susceptible to sleep-related anxiety problems. Studies are required to determine if increasing CRF could be a possible strategy for improving sleep quality.

    Objective Study the trends in Western fast food consumption (FFC) among Chinese school-age children and the association between FFC and obesity using nationwide survey data. Design Cross-sectional and longitudinal analyses were conducted to study the trends in FFC and the associations between FFC and weight status (overweight, obesity and body mass index (BMI) z-score). Setting Longitudinal data from families were collected in the 2004 and 2009 China Health and Nutrition Survey (covering nine provinces throughout China). Subjects The analysis included 2656 Chinese children aged 6 to 18 years (1542 and 1114 children in the 2004 and 2009 survey, respectively). Results FFC (reported having consumed Western fast food in the past three months) has increased between 2004 and 2009, from 18.5% to 23.9% in those aged 6–18, and increased more rapidly among those aged 13–17, from 17.9% to 26.3%. The increase was significant in almost all groups by age, sex, family income, and residence. Our cross-sectional and longitudinal analyses did not detect a significant association between FFC and obesity/overweight or BMI z-score (e.g., for BMI z-score, boys: β = 0.02, 95% CI: -0.71, 0.75; girls: β = -0.14, 95% CI: -1.03, 0.75). Conclusions FFC has increased in Chinese school-age children, especially in older children, boys, and those from low- and medium-income families, rural areas, and East China, but decreased among those from high-income families during 2004–2009. The data did not show a significant association between FFC and obesity. PMID:26974536

    We evaluated the association between anemia, overweight and obesity in a children population of a rural area in Lima.Demographic, anthropometric and hemoglobin information (from the Information System of Nutritional Status of Children, ISNSC, 2014, of schoolchildren 1-15 attending public schools under the Micro Red Pachacamac jurisdiction) were employed in a cross sectional design. Descriptive statistical and association analysis between anemia and nutritional status were carried out. Logistic regression was used to find significant variables associated to anemia.The prevalence of anemia was 10.8% (CI95% 9.5-12.0), overweight was 17.3% (CI95% 15.8-18.9) and 16.2% of children were obese (CI95% 14.7 - 17.7). No significant association between the diagnosis of anemia, overweight or obesity (chi2 = 1.68, p = 0.432) was found. However, there was an inverse significant association between the diagnosis of anemia and Body Mass Index (BMI) (z =-3.77, p = 0.000); and a higher level of hemoglobin among those over 12 y/o (ANOVA, F = 108.19, p = 0.006). In univariate analysis, only age (OR 1.14, IC95% 1.08-1.20) and IMC (OR 1.08, IC95% 1.04-1.13) were associated to anemia. There is no relationship between nutritional diagnosis of obesity, overweight and anemia in this population. However, children with older age and greater BMI were less likely to present anemia. Public policies in the last five years have focused on reducing this double nutritional problem in children.

    The aim of the study was to examine the association between sexual precocity and high-molecular weight (HMW)-adiponectin and investigate the correlation of insulin resistance and estrogen levels in obese children. In total, 60 obese children (30 boys and 30 girls) with sexual precocity were included in group A, 60 obese children (30 boys and 30 girls) without sexual precocity were included in group B, and 60 average weight children (30 boys and 30 girls) were included in group C. The levels of HMW adiponectin, fasting blood glucose, fasting insulin, luteinizing hormone (LH) peak, estradiol and testosterone were measured. The results showed that the HMW-adiponectin level of group A was the lowest and that of group C was the highest. The difference was statistically significant (P<0.05). The homeostasis model assessment of insulin resistance (HOMA-IR) and estradiol levels of group A were significantly higher than those of group B, and group B was higher than that of group C. LH peak and testosterone levels of group A were the lowest while those of group C were the highest. The differences were statistically significant (P<0.05). A subgroup analysis showed that the above results were more significant in girls. The Pearson correlation analysis revealed that the level of HMW-adiponectin was negatively correlated with HOMA-IR and estradiol (P<0.05), and positively correlated with the LH peak (P<0.05). In conclusion, sexual precocity of obese children may be associated with insulin resistance, and the link may be HMW-adiponectin. PMID:27703507

  13. Economic disruption and childhood obesity: distraction, disconnection, displacement of children's health, and a need for social change.

    PubMed

    Balog, Joseph E

    2015-04-01

    Using and adopting Simon Szreter's framework on how economic growth had a deleterious effect on children's health during the Industrial Revolution, this article presents a parallel argument that economic growth, in modern times, also has disrupted the lives of our children expressed by increasing rates of childhood obesity. A comprehensive perspective is presented that describes how economic growth in postindustrial United States has distracted our nation's attention away from a public health's concern for the health of children and social justice. The new normal of childhood obesity represents a disconnection from the harmful reality of childhood obesity and displaces the value of childhood health too far behind adult's pursuits of utility. To provide children a fair opportunity to health, and to help children secure their own future liberty and utility, children need to be able to achieve "just levels" of health that would ordinarily exist if remediable injustices that threaten health were reasonably addressed and eliminated.

    Objectives. To assess obesity risk among mothers participating in Community Kitchens and children participating in Glass of Milk (Peru food assistance programs). Methods. We analyzed prospective data from the Young Lives study. The exposure consisted in varying degrees of benefit from any of the programs (no participation in any of the programs, program participation for some months, or program participation nearly every month) at baseline (2006–2007). The outcome was overweight and obesity in mothers and children at follow-up (2009–2010). Results. Prevalence of childhood overweight and obesity was 15.5% and 5.1%, respectively; the corresponding figures for mothers were 40.5% and 14.6%. Children exposed nearly every month to the Glass of Milk program had a 65% lower risk of becoming obese compared with children not participating in the program (relative risk [RR] = 0.35; 95% confidence interval [CI] = 0.18, 0.66). Mothers participating frequently in the Community Kitchens program had almost twice the risk of becoming obese compared with those who did not participate (RR = 1.93; 95% CI = 1.18, 3.15). Conclusions. Participating in food assistance programs in Peru was associated with a lower risk of obesity in children and greater risk of obesity in mothers. PMID:27196644

    OBJECTIVE To analyze the reasons for non-adherence to follow-up at a specialized outpatient clinic for obese children and adolescents. METHODS Descriptive study of 41 patients, including information from medical records and phone recorded questionnaires which included two open questions and eight closed ones: reason for abandonment, financial and structural difficulties (distance and transport costs), relationship with professionals, obesity evolution, treatment continuity, knowledge of difficulties and obesity complications. RESULTS Among the interviewees, 29.3% reported that adherence to the program spent too much time and it was difficult to adjust consultations to patientsâ€(tm) and parentsâ€(tm) schedules. Other reasons were: childrenâ€(tm)s refusal to follow treatment (29.3%), dissatisfaction with the result (17.0%), treatment in another health service (12.2%), difficulty in schedule return (7.3%) and delay in attendance (4.9%). All denied any relationship problems with professionals. Among the respondents, 85.4% said they are still overweight. They reported hurdles to appropriate nutrition and physical activity (financial difficulty, lack of parentsâ€(tm) time, physical limitation and insecure neighborhood). Among the 33 respondents that reported difficulties with obesity, 78.8% had emotional disorders such as bullying, anxiety and irritability; 24.2% presented fatigue, 15.1% had difficulty in dressing up and 15.1% referred pain. The knowledge of the following complications prevailed: cardicac (97.6%), aesthetic (90.2%), psychological (90.2%), presence of obesity in adulthood (90.2%), diabetes (85.4%) and cancer (31.4%). CONCLUSIONS According to the results, it is possible to create weight control public programs that are easier to access, encouraging appropriate nutrition and physical activities in order to achieve obesity prevention.

    While exposure to adverse family experiences (AFEs), subset of adverse childhood experiences (ACEs), has been associated with childhood obesity, less is known about the impact of exposures to each type of AFE. Using 2011-2012 National Survey of Children's Health data, we evaluated associations between exposure to individual AFEs and overweight/obesity status in children 10years or older, adjusting for socio-demographic factors. Caregivers reported their child's height, weight, and exposure to nine AFEs; body mass index (BMI) was classified by Center for Disease Control and Prevention's (CDC) guidelines. At Mayo Clinic, we calculated frequencies and weighted estimates of socio-demographic factors and AFEs. Unadjusted and adjusted weighted multinomial logistic regression models were employed to assess the independent associations of each AFE and the different AFE composite scores with BMI category. Exposure to two or more AFEs was independently associated with increased odds of overweight (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.13, 1.56) and obese (OR, 1.45; 95% CI, 1.21, 1.73) status after adjustment for age, household income, parents' education-level, race and sex. Death of parent (OR, 1.59; 95% CI, 1.18, 2.15) and hardship due to family income (OR, 1.26; 95% CI, 1.06, 1.50) were independently associated with obesity status with adjustment for other AFEs and socio-demographic factors. Our results suggest that, in addition to cumulative exposure to AFEs, exposure to certain childhood experiences are more strongly associated with childhood obesity than others. Death of parent and hardship due to family income are individual AFEs, which are strongly predictive of obesity.

  17. Association between obesity and asthma in 4-11 year old children in the UK

    BACKGROUND—There is evidence of a positive association between asthma and obesity in adults and in children. We investigated, in a large sample of English and Scottish primary school children, whether there is a consistent association between fatness and asthma symptoms in Britain.
METHODS—A cross sectional analysis was made of 18 218 children aged 4-11 years who participated in the 1993 or 1994 surveys of the National Study of Health and Growth (NSHG). Children belonged either to English or Scottish representative samples, or an English inner city sample. Asthma attacks in the previous year, occasional wheeze, or persistent wheeze were the symptoms used in the analysis. Body mass index (BMI) and the sum of triceps and subscapular skinfolds converted to standard deviation scores (SDS) were used to assess levels of fatness.
RESULTS—A total of 14 908 children (81.8%) were included in the analysis. In the multiple logistic analysis BMI and asthma (asthma attacks or wheeze) were associated in the representative sample (OR for the comparison of the 10th and 90th centiles of BMI 1.28,95% CI 1.11 to 1.48), but sum of skinfolds was unrelated to asthma symptoms in most analyses. The association between asthma and BMI was stronger in girls than in boys in the inner city sample, but less convincingly in the representative sample.
CONCLUSIONS—Levels of obesity are associated with asthma symptoms regardless of ethnicity. The association is more consistent for BMI than for sum of skinfolds, partly because obese children are more advanced in their maturation than other children. There is some evidence that, as in adults, the association is stronger in girls than in boys, but only in the multiethnic inner city sample.

    Background Fructose intake is associated with NAFLD (Non-Alcoholic Fatty Liver Disease) development. Objective To measure fructose absorption/metabolism in pediatric NAFLD compared to obese and lean controls. Methods Children with histologically proven NAFLD, and obese and lean controls received oral fructose (1 gm/kg ideal body weight). Serum glucose, insulin, uric acid, and fructose, urine uric acid, urine fructose, and breath hydrogen levels were measured at baseline and multiple points until 360 minutes after fructose ingestion. Results Nine NAFLD (89% Hispanic, mean age 14.3 years, mean BMI 35.3 kg/m2), 6 Obese Controls (67% Hispanic, mean age 12.7 years, mean BMI 31.0 kg/m2), and 9 Lean Controls (44% Hispanic, mean age 14.3 years, mean BMI 19.4 kg/m2) were enrolled. Following fructose ingestion, NAFLD vs. Lean Controls had elevated serum glucose, insulin, and uric acid (p<0.05), higher urine uric acid (p=0.001) but lower fructose excretion (p=0.002) and lower breath hydrogen 180-min AUC (p=0.04). NAFLD vs. Obese Controls had similar post-fructose serum glucose, insulin, urine uric acid, and breath hydrogen, but elevated serum uric acid (p<0.05) and lower urine fructose excretion (p=0.02). Conclusions Children with NAFLD absorb and metabolize fructose more effectively than lean subjects, associated with an exacerbated metabolic profile following fructose ingestion. PMID:24961681

    A perturbation of zinc metabolism has been noted in subjects with obesity. The present work intends to investigate whether the zinc nutritional status is associated with hyperinsulinemia in obesity. A study was carried out in a group of obese children and adolescents (n=23) and compared to a control group (n=21), both between 7 and 14 yr of age. Software analyzed diet information from 3-d food records. Body composition was evaluated by body mass index (BMI), bioelectrical impedance, and skin-fold measurements. Zinc nutritional status was evaluated by Zn determination in plasma, erythrocyte, and 24-h urine, by atomic absorption spectrophotometry (lambda=213.9 nm). Insulin was measured by radioimmunoassay (Linco Res). Diets consumed by both groups had marginal concentrations of zinc. Zinc concentrations in plasma and erythrocytes were significantly lower in the obese group. Urinary zinc excretion and serum insulin were significantly higher in the same group, although the insulinemia and the parameters of zinc nutritional status were not significantly correlated. As a result, considering that zinc is part of the synthesis and secretion of this hormone, an assessment is necessary of the possible participation of the oligoelement in the mechanisms of insulin resistance, commonly present in obese patients.

  1. Predictors of Obesity in a Cohort of Children Enrolled in WIC as Infants and Retained to 3 Years of Age.

    This longitudinal study of children enrolled as infants in the New York State (NYS) Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) examined predictors of obesity (body mass index ≥ 95th percentile) at 3 years of age. NYS WIC administrative data which included information from parent interviews and measured heights and weights for children were used. All 50,589 children enrolled as infants in WIC between July to December 2008 and July to December 2009 and retained in WIC through age three were included. At 3 years of age, 15.1% of children were obese. Multiple logistic regression analysis showed that children of mothers who received the Full Breastfeeding Food Package when their infant was enrolled in WIC (adjusted OR = 0.52) and children with ≤2 h screen time daily at age 3 (adjusted OR = 0.88) were significantly less likely to be obese (p < 0.001) controlling for race/ethnicity, birth weight, and birthplace. In this cohort of NYS WIC participants, maternal receipt of the Full Breastfeeding Food Package (a surrogate measure of exclusive breastfeeding) is associated with lower levels of obesity in their children at age 3. The relationships between participation in WIC, exclusive breastfeeding, and obesity prevention merit further study.
