Abstract
Obesity has become a serious medical condition where many factors can contribute to excess weight gain. The most common type of childhood obesity is simple obesity, which is due to gene-obesogenic environment interaction. Only a minority are due to pathological causes. Secondary causes of obesity, while less common, include these: genetic syndromes, drug-related obesity, as well as endocrine disorders (hypothyroidism, Cushing's syndrome, growth hormone deficiency, hypogonadism, pseudohypoparathyroidism type Ia, insulinoma, hypothalamic obesity and polycystic ovary syndrome). Given that some conditions may be treatable, physicians must be aware of obesity due to endocrinopathies and distinguish them from simple obesity, and treat them properly. Although rare among children, early detection of the endocrine cause of obesity leads to reduced morbidity and, in some cases, reduced mortality in these individuals. The aim of this review is to summarize the current findings on obesity-related endocrinopathies in children (illustrated by clinical examples), highlighting aspects of pathogenetic mechanisms, genetics, the clinical diagnosis, growth, body mass index and possible therapeutic approaches. Early detection and correction of endocrine obesity is of paramount importance for obese children who could benefit from timely diagnosis and an improved management of obesity as many disturbances related to obesity can be reversed at the early stage, if weight loss is achieved.

Abstract
Glioblastoma multiforme (GBM) is a malignant primary tumor type of the central nervous system (CNS). This type of brain tumor is rare and is responsible for 12-15% of all brain tumors. The typical survival rate of GBM is only 12 to 14 months. GBM has a poor and unsatisfactory prognosis despite advances in research and therapeutic interventions via neurosurgery, radiation, and chemotherapy. The molecular heterogeneity, aggressive nature, and occurrence of drug-resistant cancer stem cells in GB restricts the therapeutic efficacy. Interestingly, the CNS tumors in children are the second most usual and persistent type of solid tumor. Since numerous research studies has shown the association between obesity and cancer, childhood obesity is one of the potential reasons behind the development of CNS tumors, including GBM. Obesity in children has almost reached epidemic rates in both developed and developing countries, harming children's physical and mental health. Obese children are more likely to face obesity as adults and develop non-communicable diseases such as diabetes and cardiovascular disease as compared to adults with normal weight. However, the actual origin and cause of obesity are difficult to be pointed out, as it is assumed to be a disorder with numerous causes such as environmental factors, lifestyle, and cultural background. In this narrative review article, we discuss the various molecular and genetic drivers of obesity that can be targeted as potential contributing factors to fight the development of GBM in children.

Transcriptional modulation of inflammation, and aging in Indian obese adults following a 12-week yoga-based lifestyle intervention: A randomized controlled trial. Front Med (Lausanne) 2022; 9:898293. [PMID: 36004368 PMCID: PMC9393383 DOI: 10.3389/fmed.2022.898293] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 07/19/2022] [Indexed: 11/29/2022] Open
Abstract
Introduction Obesity is one of the major global problems in today's world, both in children, and the adult age group. Current evidence suggests obesity alters the expression of various genes related to oxidative stress, inflammation, and aging. In recent times complementary therapy like yoga-based lifestyle intervention (YBLI) is used as an adjunct therapy to modern medicine. This study examines the efficacy of 12 weeks of yoga-based lifestyle intervention with standard care (SC) on the expression of genes related to oxidative stress, inflammation, and aging in obese adults. Methods This was a two-arm parallel randomized control trial implemented at Integral Health Clinic (IHC), an outpatient facility that regularly conducted YBLI programs for the prevention of lifestyle diseases like obesity and diabetes in the Department of Physiology, All India Institute of Medical Sciences (AIIMS), New Delhi. Blood samples at baseline and weeks 2,4, and 12 were collected from 72 adults (male n = 21; female n = 51) of age 20–45 years with a body–mass index (BMI) of 25–35 kg/m2 who were randomized to receive either a 12-week SC (n = 36) or YBLI (n = 36). SC included recommendations for the management of obesity as per Indian guidelines including a low-calorie individualized diet and physical activity. Asana (physical postures), pranayama (breathing exercises), and meditation were all part of the YBLI. Primary outcomes were relative fold change in the expression of genes associated with oxidative stress [Nuclear factor-kappa B (NF-Kappa B)], inflammation [Tumor necrosis factor-α (TNFα), interleukin-6 (IL-6)], and aging [human telomerase reverse transcriptase (TERT)] in peripheral blood mononuclear cells between the two groups at week-12. Results There were no significant changes in fold change of TERT, IL-6, and NF-kappa B between the groups at week 12. The relative fold change of TERT was significantly greater in the YBLI group (p = <0.0001) vs the SC group at 2 weeks. The relative fold change of TNF α was significantly lower at week 12 in YBLI though the change was not continuous and reliable. Within both groups, TERT expression was significantly increased at week 2 though the change was greater in the YBLI group (p < 0.0001). TNF α gene expression was significantly lower at weeks 2 and 4, compared to baseline level, in the SC group but it increased at week 12. Conclusion The results while did not confirm our hypothesis, are important to share with the scientific society, to be able to improve prospective study designs and find optimal time/intervention/biological marker settings for this highly important scientific field. The results are suggestive of a positive impact of YBLI and SC on the fold change of aging-related TERT gene in obesity, though the benefit was not evident till week 12. However, the results should be evaluated with caution and in light of other published studies. To better understand the positive effects of YBLI on oxidative stress, inflammation, and aging-related gene expression in obesity, larger studies are recommended.

Abstract
Objective: Telomere length (TL) is a robust marker of biological aging, and increased telomere attrition is noted in adults with obesity. The primary objective of this systematic review was to summarize current knowledge on the effects of childhood obesity in TL. The secondary objective was to assess the effect of weight management interventions in TL. Methods: The following databases were searched: PubMed, Scopus, Web of Science and Heal-link.gr from inception to September 2021. The search was performed using the following combinations of terms: “telomer*” [All Fields] AND (“length” [All Fields] OR “lengths” [All Fields]) AND “obes*” [All Fields] AND (“child*” [All Fields] OR “adolescen*” [All Fields]). Results: A total of 16 original articles were included in this systematic review. Eleven of them were cross-sectional and five were lifestyle interventions. Conclusions: There was a tendency towards a negative association between childhood obesity and TL. Life-style interventions in children have been associated with increased TL peripherally, indicating a possible association of the redistribution of younger cells in the periphery with the favorable effect of these interventions. Further prospective studies with larger sample sizes that employ other markers of cell aging would potentially elucidate this important mechanistic relation.

Abstract
Background: Telomeres and telomerase are considered cardinal biomarkers of cellular aging. Shorter telomeres and low telomerase activity have been associated with obesity and accelerated aging. Objective: To compare the effects of a yoga-based lifestyle intervention (YBLI) with the standard of care (SOC) on cellular aging by estimating telomere length (TL) and telomerase activity in obesity. Design and setting: A parallel, two-arm, randomized-controlled trial was conducted at the Integral Health Clinic, Department of Physiology, All India Institute of Medical Sciences, New Delhi, from March 2017 to October 2019. Participants: Obese (n = 72), body mass index (BMI), 25-35 kg/m2, aged 20-45 years, male (21), and female (51). Intervention: Seventy-two obese participants were randomized to receive either a 12-week SOC (n = 36) or YBLI (n = 36). SOC included management of obesity as per Indian guidelines including a hypocaloric individualized diet and physical activity. The pretested YBLI included asana (physical postures), pranayama (breathing exercises), and meditation. Methods: Blood samples were collected from both the groups at baseline, 2, 4, and 12 weeks. DNA was extracted from peripheral blood mononuclear cells. TL was measured by quantitative PCR, and serum telomerase levels by immunoassay. Outcome measures: Primary outcome measures were the changes in the TL and telomerase levels between the two groups at week 12. Secondary outcome measures were the changes in TL and telomerase, and anthropometric parameters (body weight, BMI, waist-to-hip ratio) at 2, 4, and 12 weeks of intervention in both SOC and YBLI groups. Results: There were no significant changes in TL and telomerase levels between the groups at week 12. The TL was significantly greater in the YBLI group versus the SOC group (p < 0.0001) at 2 weeks. The anthropometric and physiological parameters were influenced positively by both SOC and YBLI. Conclusion: The study did not meet the primary objective, although the results are suggestive of a positive impact of YBLI on aging in obesity as noted within the YBLI group. However, the results should be interpreted carefully, and in the light of other published data. Larger studies to better understand the possible positive benefits of YBLI on cellular aging are recommended. Clinical Trail Registration No. CTRI/2016/08/007136.

Abstract
INTRODUCTION One of the current criteria for bariatric surgery is to be of an age between 18 and 65 years. In all the available literature, there is a lack of studies focusing on the results of bariatric surgery in younger patient. This could be of great interest because the weight loss response can be altered by differences in metabolism or compliance rate. In recent years, a high amount of patients between 18 and 25 years of age have undergone bariatric surgery in our center, and it is our aim to evaluate the weight loss results in this youngest patient group. METHODS All preoperative and perioperative data from patients aged 18-25 and 35-55 years (control group) were collected retrospectively. Bariatric procedures took place between 2011 and 2014. Follow-up data were gathered prospectively by collecting (laboratory) measurements and questionnaires. RESULTS In total, 103 young adults (mean age 22.5) were matched to 103 adult control patients (mean age 42.6) on BMI and date of surgery. Of the young adults' group, 75 patients underwent a Roux-en-Y gastric bypass (RYGB) compared with 80 patients in the control group. Three years after RYGB, mean %total body weight loss (%TBWL) was 34 (± 9) and 30.3 (± 9) (p = 0.03), respectively. CONCLUSION Bariatric surgery is effective in young adults, and results after RYGB are even better compared with age groups in which bariatric surgery is most often performed. The high remission rate of comorbidities shows the importance of effective treatment options at a young age and preventing damaging effects in the long term.

Abstract
In the last few years, a significant increase of childhood obesity incidence unequally distributed within countries and population groups has been observed, thus representing an important public health problem associated with several health and social consequences. Obese children have more than a 50% probability of becoming obese adults, and to develop pathologies typical of obese adults, that include type 2-diabetes, dyslipidemia and hypertension. Also environmental factors, such as reduced physical activity and increased sedentary activities, may also result in increased caloric intake and/or decreased caloric expenditure. In the present review, we aimed to identify and describe a specific panel of parameters in order to evaluate and characterize the childhood obesity status useful in setting up a preventive diagnostic approach directed at improving health-related behaviors and identifying predisposing risk factors. An early identification of risk factors for childhood obesity could definitely help in setting up adequate and specific clinical treatments.

Abstract
BACKGROUND Childhood obesity-related metabolic derangements are increasing among South Asian populations. Dietary and physical activity plans have limited effect. This study aims to assess the effectiveness of metformin in the management of obesity among 8- to 16-year-old children in Gampaha District of Sri Lanka. MATERIALS AND METHODS A triple-blinded controlled trial was conducted on 150 obese school children. After 12-hour overnight fast, blood was drawn for fasting blood glucose (FBG) and lipid profile. Anthropometry, fat mass (FM), and blood pressure were measured. BMI and insulin resistance were calculated. Children randomly received either metformin (8-10 years-500 mg 12 hourly; 11-16 years-1 g 12 hourly) or placebo. Anthropometry and blood investigations were repeated at 6 and 12 months. Mean difference in outcome measures, adjusted for baseline values, was compared using ANCOVA. RESULTS There were 84/150 boys. Metabolic syndrome was present in 25 (16.7%). A statistically significant adjusted mean reduction was observed in the metformin group compared with placebo, in weight (-0.991 vs. 1.394, p = 0.000), BMI/Age-standard deviation score (SDS; -0.287 vs. -0.116, p = 0.000), %FM/Age-SDS (-0.092 vs. 0.016, p = 0.04), systolic blood pressure (SBP; -0.415 vs. 0.015, p = 0.015), total cholesterol (-0.95 vs. -0.7, p = 0.001), low-density lipoprotein (-0.67 vs. -0.45, p = 0.001), and highly sensitive C-reactive protein (-1.36 vs. 0.08, p = 0.013) at 6 months, and in BMI/Age-SDS (-370 vs. -0.222, p = 0.001), WC/Age-SDS (-0.473 vs. -0.337, p = 0.018), SBP (-0.834 vs. -0.477, p = 0.023), and triglycerides (-0.33 vs. -0.14, p = 0.019) at 12 months. CONCLUSIONS Metformin compared with placebo has beneficial effects on anthropometric and metabolic indicators in the management of childhood obesity.

Abstract
BACKGROUND Body mass compartments may have different directions of influence on bone accrual. Studies of children are limited by relatively small sample sizes and typically make strong assumptions of linear regression. OBJECTIVE To evaluate associations of overall body mass, components of overall body mass (fat-free and total fat), and components of total fat mass (truncal and non-truncal fat), measured via dual-energy X-ray absorptiometry (DXA) and anthropometry, with total body less head areal bone mineral density (aBMD) Z-score in mid-childhood. METHODS We performed a cross-sectional study among 876 Boston-area children who had DXA measures. We evaluated linearity of associations using generalized additive models. RESULTS Children were median 7.7 (range 6-10) years of age, and 61% were white. After adjustment for sociodemographics and other compartments of body mass, overall body mass, particularly the fat-free mass component, appeared to have a positive relationship with aBMD Z-score [e.g., 0.25 (95% CI: 0.23, 0.28) per 1-kg fat-free mass]. The relationship between truncal fat and aBMD Z-score appeared non-linear, with a negative association only in children with levels of fat mass in the upper 15th percentile [-0.17 (95% CI: -0.26, -0.07) aBMD Z-score per 1-kg truncal fat mass], while non-truncal fat mass was not associated with aBMD Z-score. CONCLUSIONS Our analyses suggest that central adiposity is associated with lower aBMD Z-score only in children with the highest levels of abdominal fat. This finding raises the possibility of a threshold above which central adipose tissue becomes more metabolically active and thereby adversely impacts bone.

Abstract
Childhood obesity is an important public health issue worldwide. Urbanization, sedentary lifestyle and change in food habits are the chief reasons behind this pandemic. In a small proportion of children, obesity is the result of endocrine, syndromic or monogenic causes. The present paper summarizes the methods, definitions and cut-offs for identification of obesity in children. We have briefly reviewed the various techniques used for estimation of body fat in children and the cut-offs for defining obesity based on body fat percentage, and the reference curves based on body mass index and waist circumference. The etiology of obesity in children, including individual behaviors, macro- and micro-environmental influences, and endocrine causes have been discussed, and an approach to etiological assessment of obese children has been presented. Special emphasis has been laid on clinical pointers that suggest the presence of syndromic, endocrine or monogenic forms of obesity, such as, short stature, dysmorphism, neurocognitive impairment and early age at onset.

A Prototype Exercise-Empowerment Mobile Video Game for Children With Cancer, and Its Usability Assessment: Developing Digital Empowerment Interventions for Pediatric Diseases. Front Pediatr 2018; 6:69. [PMID: 29686977 PMCID: PMC5900044 DOI: 10.3389/fped.2018.00069] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2018] [Accepted: 03/08/2018] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Medical advances continue to improve morbidity and mortality of serious pediatric diseases, including cancer, driving research addressing diminished physical and psychological quality of life in children with these chronic conditions. Empowerment enhances resilience and positively influences health, disease, and therapy understanding. We describe the development and usability assessment of a prototype Empower Stars! mobile video game grounded in behavioral and exercise theories with the purpose of coupling physical exercise with empowerment over disease in children with cancer. METHODS Academic faculty, health-care providers, and community video game developers collaborated in this project. The iPadAir was selected as a delivery platform for its accelerometer and gyroscope features facilitating exercise design. Unity multiplatform technology provided animation and audiovisual features for immediate player feedback. Javascript, C#, Photoshop, Flash, and SketchUp were used for coding, creating graphical assets, Sprite sheets, and printing files, respectively. 3D-printed handles and case backing were used to adapt the iPad for physical exercise. Game usability, engagement, and enjoyment were assessed via a multilevel study of children undergoing cancer chemotherapy, their parents, and pediatric cancer health-care providers. Feedback crucial for ongoing game development was analyzed. RESULTS A prototype Empower Stars! mobile video game was developed for children 7-14 years old with cancer. Active, sedentary, educational, and empowerment-centered elements intermix for 20 min of exercise within a 30 min "one-day treatment" gameplay session involving superheroes, space exploration, metaphorical cancer challenges, life restoration on a barren planet, and innumerable star rewards. No player "dies." Usability assessment data analyses showed widespread enthusiasm for integrating exercise with empowerment over cancer and the game itself. Favorite elements included collecting star rewards and planet terraforming. Traveling in space and the Healthy Food Choice game were least liked. The need for improved gameplay instructions was expressed by all groups. The usability study provided essential feedback for converting the prototype into alpha version of Empower Stars! CONCLUSION Adapting exercise empowerment-promoting video game technology to mobile platforms facilitates usability and widespread dissemination for children with cancer. We discuss broader therapeutic applicability in diverse chronic pediatric diseases, including obesity, asthma, cystic fibrosis, diabetes, and juvenile idiopathic arthritis.

Abstract
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.

Abstract
Obesity in adolescence is a public health priority because it usually tracks into adulthood, resulting in enormous medical and social costs. This underscores the importance of early identification and intervention. Acanthosis nigricans (AN) was once considered a rare paraneoplastic dermatosis, but is now frequently observed in obese adolescents. Current understanding suggests that it is associated with insulin resistance and has a unique role in secondary prevention. The purpose of this narrative review is to provide a comprehensive overview of AN in obese adolescents, covering its history, current knowledge on the condition, its clinical significance, management challenges, and the direction of future research.

Abstract
BACKGROUND/OBJECTIVES The current literature suggests there is a possible connection between paediatric psoriasis and obesity. However, there is a paucity of research on the influence of increased adiposity on the severity of paediatric psoriasis and disease progression. We aimed to compare the prevalence of being overweight or obese in paediatric psoriasis patients and controls and assess the potential impact of being overweight/obese on disease severity and progression of disease. METHODS This multicentre prospective case-control study included 289 psoriasis patients (aged < 18 years) treated and followed up by one of the four university hospitals in Turkey. The control group consisted of 151 consecutive age-matched and sex-matched children who lacked a personal or family history of psoriasis. The participants' characteristics, psoriasis-related parametres (e.g., initial subtype, psoriasis area and severity index, presence of psoriatic arthritis) and body mass index were determined. RESULTS The difference between the prevalence of being overweight/obese among psoriatics (28%) and the control group (19%) was significant (P = 0.024). Being overweight/obese had no significant impact on disease severity and unresponsiveness to topical treatment. Within a median follow-up time of 12 months, 23% of our patients with localised disease at disease onset progressed to generalised disease. The impact of being overweight/obese on disease progression was found to be non-significant; however, disease duration was found to have a significant impact on disease progression (P = 0.026). CONCLUSIONS Although it is not associated with disease severity and course, increased bodyweight may be a health problem for psoriatic children.

Abstract
UNLABELLED This study aimed to analyze the associations between sedentary behavior, physical activity (PA), and cardiorespiratory fitness (CRF), with carotid intima-media thickness (cIMT), a marker of atherosclerosis already present at an early stage among obese adolescents. The associations between anthropometric measures, sedentary time, PA, CRF, and cIMT of 54 Caucasian obese adolescents were analyzed using partial correlations (controlling for age and sex) and multiple linear regressions. Differences between participants with and without a healthy CRF were also analyzed using independent sample t test. Sedentary time did not correlate with any of the variables. Light physical activity correlated positively with mean cIMT (r(38) = 0.36, p = 0.024). Moderate physical activity (MPA) correlated positively with both mean (r(38) = 0.37, p = 0.018) and maximum (r(38) = 0.33, p = 0.039) cIMT. CRF was inversely associated with mean cIMT (r(40) = -0.36, p = 0.019), even when controlling for sedentary time (r(37) = -0.35, p = 0.030). The best predictors of cIMT were MPA and weight. No significant differences in cIMT were found between participants with healthy and unhealthy CRF. CONCLUSION Although we need to be cautious due to the limitations of the study, the results suggest that despite the importance of decreasing sedentary time, increasing PA intensity may be more effective in improving endothelial structural health among obese adolescents.

Abstract
BACKGROUND Deficiency of vitamin B-6, vitamin B-12, folate, folic acid, or methionine may lead to dysregulation of DNA methylation, which might lead to disturbed energy and lipid metabolism. OBJECTIVE We aimed to explore whether intakes of vitamin B-6, vitamin B-12, folate, folic acid, and methionine at 1 y are associated with measures of growth and body composition at the age of 6 y. METHODS This study was performed in 2922 children participating in The Generation R Study, a population-based prospective cohort study. Dietary intakes of vitamins B-6 and B-12, folate, folic acid, and methionine were assessed at a median age of 12.9 mo by using a validated food-frequency questionnaire. At the age of 6 y, height and weight were measured, and body mass index (BMI; in kg/m(2)) was calculated. Body fat was measured with dual-energy X-ray absorptiometry, and body fat percentage and the ratio of android fat mass to gynoid fat mass (android:gynoid) were calculated. RESULTS In models adjusted for maternal and child characteristics, children with folic acid intakes in the highest tertile had a 0.16 SD score (SDS) lower weight (95% CI: -0.31, -0.02 SDS) and a 0.14 SDS lower BMI (95% CI: -0.26, -0.01 SDS) than children in the lowest tertile. Children with vitamin B-12 intakes in the highest tertile had a 0.13 SDS higher android:gynoid (95% CI: 0.00, 0.25 SDS) than children in the lowest tertile. In addition, children with intakes in the highest tertile of methionine had a 0.09 SDS higher BMI (95% CI: 0.01, 0.17) and a 0.12 SDS higher android:gynoid (95% CI: 0.02, 0.22) than children in the lowest tertile. Vitamin B-6 and folate intakes were not associated with any of the body composition outcomes measured. CONCLUSIONS In this population of children, early high folic acid intakes were associated with a lower body weight and BMI at the age of 6 y. In contrast, early higher methionine intakes were associated with unfavorable body composition at the age of 6 y. Future studies should investigate long-term consequences of these outcomes on health.

Abstract
Morbid obesity is strongly associated with nonalcoholic fatty liver disease (NAFLD), which is one of the most common causes of chronic liver disease worldwide. The present best treatment for NAFLD and nonalcoholic steatohepatitis (NASH) is weight reduction through lifestyle modification. Because of frustrating inefficiency of such a therapeutic approach, bariatric surgery is increasingly performed in adolescents as an alternative option for weight reduction. Standards of care and consensus for indications are, however, scarce. We explore the indications and limitations of bariatric surgery in children with severe obesity with and without NASH and aim to provide guidance for the exceptional indications for adolescents with extreme obesity with major comorbidity that may benefit from these controversial interventions. Present evidence suggests that bariatric surgery can decrease the grade of steatosis, hepatic inflammation, and fibrosis in NASH. Uncomplicated NAFLD is not an indication for bariatric surgery. Roux-en-Y gastric bypass is considered a safe and effective option for adolescents with extreme obesity, as long as an appropriate long-term follow-up is provided. Laparoscopic adjustable gastric banding has not been approved by the Food and Drug Administration for use in adolescents and therefore should be considered investigational. Finally, sleeve gastrectomy and other types of weight loss surgery that have grown increasingly common in adults, still need to be considered investigational. Temporary devices may be increasingly being used in pediatrics; however, future studies, including a long-term risk analysis of patients who undergo surgery, are much needed to clarify the exact indications for bariatric surgery in adolescents.

Abstract
OBJECTIVES To test how different developmental pathways of health-related physical fitness and motor competence tests relate to weight status (overweight and obesity) at the end of primary school. DESIGN Longitudinal study on growth, health-related physical fitness, and motor competence of 472 primary school children assessed yearly throughout 1st to 4th grade, with an average age of 6.3±0.7 years of age at 1st grade. METHODS Children's pathways of change on each of the fitness and motor competence tests were determined along the four years of the study. Participants were divided into three groups according to their rate of change in each test over time: Low Rate of Change, Average Rate of Change, and High Rate of Change. A logistic regression was used to predict the odds ratio of becoming overweight or obese, depending on the developmental pathway of change in fitness and motor competence across childhood. RESULTS Children with a low or average rate of change in their developmental pathways of fitness and motor competence were several times more prone to become overweight or obese at the end of primary school (OR 2.0 to 6.3), independent of sex and body mass index at baseline. Specifically, a negative developmental pathway (Low Rate of Change) in cardiorespiratory fitness demonstrated over a six-fold elevated risk of being overweight or obese, compared to peers with a positive pathway. CONCLUSIONS Not all children improve their motor competence and fitness levels over time and many actually regress over time. Developing positive fitness and motor competence pathways during childhood protects from obesity and overweight.

Abstract
Psoriasis is a common, chronic inflammatory dermatosis that often has its onset during childhood. There is increasing evidence that psoriasis in adults is associated with obesity, the metabolic syndrome, and associated comorbidities, including insulin resistance/type 2 diabetes, dyslipidemia, hypertension, and cardiovascular disease. This association is postulated to arise, at least in part, as a result of a systemic proinflammatory state that is mediated by adipose tissue. Several recent observational studies suggest that children and adolescents with psoriasis may be at increased risk of being overweight and obese as well as having an increased risk for features of the metabolic syndrome. Such an association raises concern with regards to the long-term health implications for children and adolescents with psoriasis and suggests that better awareness, evaluation, and management of overweight and obese patients and associated metabolic disease are warranted in this population.

Abstract
The present study analyses the gene expression profile of peripheral blood mononuclear cells (PBMC) from obese boys. The aims of the present study were to identify baseline differences between low responders (LR) and high responders (HR) after 10 weeks of a moderate energy-restricted dietary intervention, and to compare the gene expression profile between the baseline and the endpoint of the nutritional intervention. Spanish obese boys (age 10–14 years) were advised to follow a 10-week moderate energy-restricted diet. Participants were classified into two groups based on the association between the response to the nutritional intervention and the changes in BMI standard deviation score (BMI-SDS): HR group (n 6), who had a more decreased BMI-SDS; LR group (n 6), who either maintained or had an even increased BMI-SDS. The expression of 28 869 genes was analysed in PBMC from both groups at baseline and after the nutritional intervention, using the Affymetrix Human Gene 1.1 ST 24-Array plate microarray. At baseline, the HR group showed a lower expression of inflammation and immune response-related pathways, which suggests that the LR group could have a more developed pro-inflammatory phenotype. Concomitantly, LEPR and SIRPB1 genes were highly expressed in the LR group, indicating a tendency towards an impaired immune response and leptin resistance. Moreover, the moderate energy-restricted diet was able to down-regulate the inflammatory ‘mitogen-activated protein kinase signalling pathway’ in the HR group, as well as some inflammatory genes (AREG and TNFAIP3). The present study confirms that changes in the gene expression profile of PBMC in obese boys may help to understand the weight-loss response. However, further research is required to confirm these findings.

Abstract
OBJECTIVE Childhood obesity has become epidemic and has been accompanied by an increase in prevalence of type 2 diabetes (T2DM) in youth. Addressing obesity and insulin resistance by drug treatment represents a rational strategy for the prevention of T2DM. A systematic review was performed to evaluate the effectiveness of metformin in reducing weight and ameliorating insulin resistance in obese nondiabetic children. METHODS A PubMed database search was conducted, using 'metformin', 'obesity', 'insulin resistance', 'children', 'adolescents' as search terms. RESULTS Eleven trials were included in the present review. Metformin was administered for 6-12 months at a dosage of 1,000-2,000 mg/daily, decreasing BMI by 1.1-2.7 compared with placebo or lifestyle intervention alone. Concomitantly, fasting insulin resistance improved after metformin therapy. Posttreatment follow-up was performed in one study, showing that after 1 year of discontinuation of therapy the decrease in BMI disappears. CONCLUSIONS Short-term metformin treatment appears to moderately affect weight reduction in severely obese children and adolescents, with a concomitant improvement in fasting insulin sensitivity. Further studies with longer treatment period are needed to establish how much metformin can reduce weight and its real utility in preventing T2DM development in pediatric patients.

Abstract
Context Telomeres are biomarkers of biological aging. Shorter telomeres have been associated with increased adiposity in adults. However, this relationship remains unclear in children and adolescents. Objective To evaluate the association between telomere length (TL) and adiposity markers in overweight/obese adolescents after an intensive program. We hypothesize that greater TL at baseline would predict a better response to a weight loss treatment. Design, Setting, Patients and Intervention The EVASYON is a multidisciplinary treatment program for adolescents with overweight and obesity that is aimed at applying the intervention to all possibly involved areas of the individual, such as dietary habits, physical activity and cognitive and psychological profiles. Seventy-four participants (36 males, 38 females, 12–16 yr) were enrolled in the intervention program: 2 months of an energy-restricted diet and a follow-up period (6 months). Main Outcome TL was measured by quantitative real-time polymerase chain reaction at baseline and after 2 months; meanwhile, anthropometric variables were also assessed after 6 months of follow-up. Results TL lengthened in participants during the intensive period (+1.9±1.0, p<0.001) being greater in overweight/obese adolescents with the shortest telomeres at baseline (r = −0.962, p<0.001). Multivariable linear regression analysis showed that higher baseline TL significantly predicted a higher decrease in body weight (B = −1.53, p = 0.005; B = −2.25, p = 0.047) and in standard deviation score for body mass index (BMI-SDS) (B = −0.22, p = 0.010; B = −0.47, p = 0.005) after the intensive and extensive period treatment respectively, in boys. Conclusion Our study shows that a weight loss intervention is accompanied by a significant increase in TL in overweight/obese adolescents. Moreover, we suggest that initial longer TL could be a potential predictor for a better weight loss response.

Abstract
PURPOSE Childhood obesity is an increasing problem in affluent societies throughout the world. We sought to identify the impact of obesity on the outcome of inflammatory bowel disease (IBD) and determine differences (if any) between ulcerative colitis (UC) and Crohn's disease (CD). METHODS The 2009 Kids' Inpatient Database was explored for all children (≤ 20 years) admitted with IBD. ICD-9 codes were used to identify obesity and complications, including hemorrhage, perforation, and complex fistulas. Logistic regression analysis accounting for demographics, underlying disease, surgical procedures, and obesity was performed to identify factors associated with complication development. Data are expressed as odds ratios (OR) and a 95% confidence interval (CI). A P value of 0.05 was regarded as significant. RESULTS From 12,465 admissions, 164 children were obese (1.3%), with no difference between CD and UC (1.3% vs. 1.4%; P=0.60). Girls had a two-fold increase in obesity (OR: 2.06, CI: 1.48-2.86; P<0.01). Obesity had no effect on elective/emergent admission rate (OR: 0.85, CI: 0.54-1.35; P=0.49), perforation (OR: 0.76, CI: 0.13-4.46; P=0.76), hemorrhage (OR: 0.64,CI: 0.34-1.21; P=0.17), complex fistula (OR: 1.19, CI: 0.45-3.17; P=0.72), or requirement for surgery (OR: 0.80, CI: 0.48-1.31; P=0.37). While the overall clinical morbidity rate was 10.7%, obesity was not associated with the development of overall complications (OR 1.20, CI: 0.75-1.93; P=0.45) or length of stay (6.36 vs. 6.10 days; P=0.61). Obesity increased the rate of central venous catheter (CVC) infections (OR: 10.98, CI: 2.50-48.20; P<0.01). CONCLUSIONS Obesity was more prevalent in girls with IBD. While obesity did not alter disease severity, rate of surgical intervention, or hospital length of stay, it was associated with higher CVC infections.

Abstract
OBJECTIVE HDL regulates endothelial function via stimulation of nitric oxide production. It is documented that endothelial function is impaired in obese adolescents, and improved by lifestyle interventions (LI). DESIGN AND METHODS HDL function in obese adolescents and the impact of LI or Roux-en-Y gastric bypass surgery (RYGB) was assessed. HDL was isolated from 14 adolescents with normal body mass index (HDLcontrol ), 10 obese (HDLobese ) before and after 6 month LI, and five severe obese adolescents before and one year after RYGB. HDL-mediated phosphorylation of endothelial nitric oxide synthase (eNOS)-Ser(1177) , eNOS-Thr(495) , and PKC-ßII was evaluated. In addition the HDL proteome was analyzed. RESULTS HDLobese -mediated eNOS-Ser(1177) phosphorylation was reduced, whereas eNOS-Thr(495) phosphorylation increased significantly when compared to HDLcontrol . No impact of obesity was observed on PKC-ßII phosphorylation. LI and RYGB had no impact on HDL-mediated phosphorylation of eNOS and PKC-ßII. A principle component plot analysis of the HDL particle separated controls and severe obese, whereas the interventions did not trigger sufficient differences to the HDL proteome to permit distinction. CONCLUSION These results demonstrated that HDL-function is impaired in obese adolescents, and that LI or RYGB did not correct this dysfunction. This might be an argument for developing earlier prevention strategies in obese adolescents to avoid HDL dysfunction.

Abstract
BACKGROUND Morbid obesity continues to be a significant problem within the United States, as overweight/obesity rates are nearing 33%. Bariatric surgery has had success in treating obesity in adults and is becoming a viable treatment option for obese adolescents. METHODS We studied 1615 inpatient admissions for children ≤20 years of age undergoing a bariatric procedure for morbid obesity in 2009 using the Kids' Inpatient Database (KID). Patients had a principal diagnosis of obesity and a bariatric procedure listed as one of their first 5 procedures. Procedures (open gastric bypass, laparoscopic gastric bypass, sleeve gastrectomy, laparoscopic gastroplasty, and laparoscopic gastric band) and complications were defined by ICD-9 codes. RESULTS There were 90 open gastric bypasses, 906 laparoscopic gastric bypasses, 150 sleeve gastrectomies, 18 laparoscopic gastroplasties, and 445 laparoscopic gastric bandings. The length of stay for each procedure was 2.44, 2.20, 2.33, 1.10, and 1.02 days, respectively (P<0.001). The complication rates were 3.3%, 3.5%, 0.7%, 0.0%, 0.2%, respectively (P=0.004). CONCLUSIONS Bariatric surgery is an increasingly utilized option for the treatment of morbid obesity among adolescents. The procedures can be performed safely as evidenced by low complication rates. Additional long-term follow-up is necessary.

Abstract
It is the position of the Academy of Nutrition and Dietetics that prevention and treatment of pediatric overweight and obesity require systems-level approaches that include the skills of registered dietitians, as well as consistent and integrated messages and environmental support across all sectors of society to achieve sustained dietary and physical-activity behavior change. This position paper provides guidance and recommendations for levels of intervention targeting overweight and obesity prevention and treatment from preschool age through adolescence. Methods included a review of the literature from 2009 to April 2012, including the Academy's 2009 evidence analysis school-based reviews. Multicomponent interventions show the greatest impact for primary prevention; thus, early childhood and school-based interventions should integrate behavioral and environmental approaches that focus on dietary intake and physical activity using a systems-level approach targeting the multilevel structure of the socioecological model as well as interactions and relationships between levels. Secondary prevention and tertiary prevention/treatment should emphasize sustained family-based, developmentally appropriate approaches that include nutrition education, dietary counseling, parenting skills, behavioral strategies, and physical-activity promotion. For obese youth with concomitant serious comorbidities, structured dietary approaches and pharmacologic agents should be considered, and weight-loss surgery can be considered for severely obese adolescents. Policy and environmental interventions are recommended as feasible and sustainable ways to support healthful lifestyles for children and families. The Academy supports commitment of resources for interventions, policies, and research that promote healthful eating and physical-activity behaviors to ensure that all youth have the opportunity to achieve and maintain a weight that is optimal for health.

Abstract
OBJECTIVE To conduct a process evaluation of the Living Green, Healthy and Thrifty (LiGHT) program, a novel virtual child obesity management program that combines health promotion with ecology and economy (Phase 1). METHODS We carried out a mixed methods process evaluation involving qualitative and quantitative data collection in 3 phases: among 3 child-parent units, (group 1) that informed program development; 9 child-parent units (group 2) that tested the draft program and further aided program refinement; and 17 child-parent units (group 3) for a 4-week pilot of the program. In the program pilot, we assessed participants' knowledge and readiness to change pre- and postintervention and explored perceptions of the program. RESULTS Participants generally felt that the online format for program delivery was convenient and accessible, the content was practical, and the integration of health-environment-economy was well received. Many parents also appreciated the involvement of the family. However, the lack of visual appeal and overabundance of text was identified as a challenge, and children/youth in particular requested assurance that their personal information (e.g. weight) was not seen by their parents. The online method of program delivery holds the unique challenge of requiring special efforts to create a sense of personal connection and community. The presence of a "Way-finder" to assist participants and discussion boards/forums are potential solutions. CONCLUSION The LiGHT online weight management program offers an accessible, convenient weight management resource that children and families appreciate for its availability, broader educational scope, and practicality. Outcome evaluation of LiGHT will be carried out in Phase 2 of the project.
