Investigation of Underlying Association between Anthropometric and Cardiorespiratory Fitness Markers among Overweight and Obese Adolescents in Canada. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:408. [PMID: 38673321 PMCID: PMC11049930 DOI: 10.3390/ijerph21040408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 03/21/2024] [Accepted: 03/25/2024] [Indexed: 04/28/2024]
Abstract
BACKGROUND Adolescents who experience overweight or obesity commonly persist in these conditions into adulthood, thereby elevating their vulnerability to health issues. The focus of this study is on health risk markers such as body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), body surface area (BSA), and cardiorespiratory fitness (CRF). The objectives include updating normative values for BMI, WC, WHtR, and BSA in Canadian adolescents, establishing cardiometabolic risk zones, and developing a composite score considering both anthropometric and CRF markers. METHODS Involving 1864 adolescents, the study used the LMS method to generate percentile norms, stratified by age and sex. Cardiometabolic risk zones were established for each marker based on Z-scores, and a composite score was created. RESULTS An increase in WC of 5.8 and 7.4 cm for boys and girls, respectively, was observed since 1981. Forward multiple regression analyses were conducted to assess the robustness and validity of the proposed model. The results indicated that the model explained nearly 90% (R2 = 0.890) of the common variance between the composite score and the retained independent variables. Moreover, the model demonstrated a mean absolute error (MAE) of approximately 6 percentiles, confirming its high precision. Furthermore, these analyses yielded key thresholds for identifying adolescents at risk: the 70th percentile for high cardiometabolic risk and the 85th percentile for very-high risk. CONCLUSIONS Individually, WC or WHtR seem to be better markers for evaluating cardiometabolic risk than BMI during adolescence. However, CRF showed comparable importance to anthropometric markers in determining cardiometabolic risk. The simultaneous inclusion of anthropometric and CRF markers provides a better picture of the global cardiometabolic risk in adolescents.

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.

Evaluation of catch-up growth in severe pediatric Hashimoto's hypothyroidism. Arch Pediatr 2023; 30:142-148.

Abstract
BACKGROUND We aimed to evaluate catch-up growth in children with severe Hashimoto's hypothyroidism (HH) after thyroid hormone replacement therapy (HRT). METHODS A multicenter retrospective study was conducted including children referred for growth slowdown that led to the diagnosis of HH between 1998 and 2017. RESULTS A total of 29 patients were included, with a median age of 9.7 years (13-172 months). Median height at diagnosis was -2.7 [-4.6; -0.1] standard deviation score (SDS), with a height loss of 2.5 [0.7; 5.4] SDS compared to height before growth deflection (p<0.0001). At diagnosis, the median TSH level was 819.5 mIU/L [100; 1844], the median FT4 level was 0 pmol/L [undetectable; 5.4], and the median anti-thyroperoxidase antibody level was 1601 UI/L [47; 25,500]. In the 20 patients treated only with HRT, there were significant differences between height at diagnosis and height at 1 year (n = 19, p<0.0001), 2 years (n = 13, p = 0.0005), 3 years (n = 9, p = 0.0039), 4 years (n = 10, p = 0.0078), and 5 years (n = 10, p = 0.0018) of treatment but not in the case of final height (n = 6, p = 0.0625). Median final height was -1.4 [-2.7; 1,5] SDS (n = 6), with a significant difference between height loss at diagnosis and total catch-up growth (p = 0.003). The other nine patients were also given growth hormone (GH). They were smaller at diagnosis (p = 0.01); however, there was no difference in final height between those two groups (p = 0.68). CONCLUSION Severe HH can lead to a major height deficit, and catch-up growth seems to be insufficient after treatment with HRT alone. In the most severe cases, administration of GH may enhance this catch-up.

Abstract
INTRODUCTION/OBJECTIVE The lack of international consensus on the definition of Metabolic Syndrome (MS) in the pediatric population makes it difficult to estimate its prevalence. In this study, we intend to identify MS prevalence and a cutoff point based on a continuous score in children aged four to seven years. METHODS A cross-sectional study of 402 children (4-7 years) monitored by the Lactation Support Program (PROLAC). A continuous MS risk score was assessed using Principal Component Analysis (PCA). In order to calculate the score, the following MS risk factors were considered: Waist circumference (WC), High Density Lipoprotein (HDL), Triglycerides (TG), Blood Pressure (BP) and Blood sugar. Using a Receiver Operating Characteristics (ROC) curve, the cutoff point for predicting MS risk based on continuous score was evaluated. RESULTS A progressive increase in MS scores was observed according to increase in the number of risk factors. This increase was also observed when comparing boys and girls (p < 0.001). In the absence of MS, the median score among the children was -0.0486 (-0.2929-0.2151). For children with MS, the median score was 0.5237 (0.2286-0.7104) (p < 0.001). The best cutoff score for predicting MS in children aged four to five years was >0.09 (100% sensitivity and specificity 72.67%). For children aged six to seven years, this value was >0.14 (100% sensitivity and 64.65% specificity). CONCLUSION The calculated continuous risk score can predict MS with good accuracy and high sensitivity and reasonable specificity.

The association between sleeping behavior, obesity, psychological depression, and eating habits among adolescents in the emirate of Abu Dhabi–United Arab Emirates. PLoS One 2022; 17:e0269837. [PMID: 36040982 PMCID: PMC9426872 DOI: 10.1371/journal.pone.0269837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Accepted: 05/28/2022] [Indexed: 11/21/2022] Open
Abstract
Objective The study aimed to investigate the association between sleeping behavior (specifically sleep duration), body mass index (BMI), eating habits, and psychological mood depression among adolescents in the Emirate of Abu Dhabi- UAE. Methods and materials A subsample of three hundred and ninety-five participants (209 females and 186 males) from middle and high schools (aged 12–18 years) in the emirate of Abu Dhabi completed the surveys in the presence of their parents and two research assistants. Measures of daytime sleepiness and other sleep parameters (sleep duration on weekdays and weekends), eating habits, and mood depression questionnaires were reported. Results Differences in BMI between males and females were statistically significant (26.12 ± 4.5 vs. 24.4 ± 4.3; p < 0.01). There was a negative linear association (p < 0.01) between the students’ BMI and the weekday/ weekend sleep duration. The average weekday and weekend sleep duration ranged from 5.7 hours (weekdays) to 9.3 hours(weekend). The study showed that an increase in BMI was correlated to mood depression (r = 0.396, p<0.01). In terms of eating habits, there was a significant association between eating unhealthy food and sleep duration; 72.6% of students who slept less than 6 hours reported unhealthy eating habits (p <0.05). Conclusion The study showed a clear association between short sleep duration and obesity among adolescents in the UAE. This relationship between sleep duration and obesity is less studied and less understandable. Future research about exploring how sleeping behaviors can affect obesity during adolescence can support understanding this association and create an effective intervention.

Correlations between Physical Fitness and Body Composition among Boys Aged 14–18—Conclusions of a Case Study to Reverse the Worsening Secular Trend in Fitness among Urban Youth Due to Sedentary Lifestyles. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148765. [PMID: 35886622 PMCID: PMC9323754 DOI: 10.3390/ijerph19148765] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 07/13/2022] [Accepted: 07/14/2022] [Indexed: 11/16/2022]
Abstract
A secular trend can be observed throughout the world with an increase in childhood obesity and a decrease in fitness. The research aimed to examine the results of tests measuring the conditional abilities of young boys aged 14–18 in fitness tests and their correlations with body composition indicators. That was supported by research that has been prepared in Hungary so far. This research focuses on the results of fitness tests conducted on 14- to 18-year-old boys, presented along with body composition data. The authors sought to describe the development of the fitness profiles of males at a Budapest secondary school participating in the research, based on the results of the Hungarian National Student Fitness Test (NETFIT®), and also how their physical characteristics affect the results of NETFIT® tests in the sample measured. A total of 735 male high school students at a Budapest secondary school (14–18 years old) (mean ± SD, 16.05 ± 1.18 years) participated in the survey. The data were collected in the 2018/2019 academic year, and it was compared with the national data. The correlation between the performance indicators of the NETFIT® tests and the physical characteristic indicators was analyzed using the two-block Partial Least Squares method. In the resulting groups, Kruskal–Wallis variance analysis was performed to investigate the differences in performance. In contrast, pairs of group differences were tested with the Mann–Whitney test. Boys with a short physique were at some advantage in trunk-lifts and push-ups, compared to taller boys. It was also obvious that being overweight is a hindrance regarding the PACER test or the standing broad jump. The handgrip in the left and right hand was mostly of similar strength or weakness. Tall-heavy children performed better in this test. The grip strength of tall-thin students was also strong, but not as strong as in the tall-heavy group. Reducing the percentage of body fat (PBF) and creating the optimal BMI index is important for the younger age group, as our results have clearly demonstrated that overweight is a hindrance in the PACER, VO2 max, standing broad jump, back-saver sit-and-reach, and push-up tests.

Abstract
Over the last four decades, the escalation in diabetes and obesity rates has become epidemic all over the world. Diabesity describes the strong link between T2D and obesity. It correlates deeper with the elevated risks of developing cardiovascular disease hypertension, stroke, and several malignancies. Therapeutic usage of medicinal plants and natural products in the treatment of diabetes and obesity has long been known to physicians of Greco-Arab and Islamic medicine. Improved versions of their abundant medicinal plant-based formulations are at present some of the most popular herbal treatments used. Preclinical and clinical data about medicinal plants along with their bioactive constituents are now available, justifying the traditionally known therapeutic uses of products derived from them for the prevention and cure of obesity-related T2D and other health problems. The aim of this review is to systematize published scientific data dealing with the efficiency of active ingredients or extracts from Middle Eastern medicinal plants and diet in the management of diabesity and its complications. Google Scholar, MEDLINE, and PubMed were searched for publications describing the medicinal plants and diet used in the management of T2D, obesity, and their complications. The used keywords were “medicinal plants” or “herbals” in combination with “obesity,” “diabetes,” “diabetes,” or nephropathy. More than 130 medicinal plants were identified to target diabesity and its complications. The antidiabetic and anti-obesity effects and action mechanisms of these plants are discussed here. These include the regulation of appetite, thermogenesis, lipid absorption, and lipolysis; pancreatic lipase activity and adipogenesis; glucose absorption in the intestine, insulin secretion, glucose transporters, gluconeogenesis, and epigenetic mechanisms.

Abstract
Public health policies aimed at obesity reduction are more often directed toward adults than children. This is alarming given that rates of childhood obesity have been steadily increasing, and, if not treated early, adolescents with obesity may develop comorbidities into adulthood. Lifestyle-based interventions are the cornerstone of childhood obesity treatment. Recently, extended-reality (XR)-based interventions have been incorporated into the treatment of obesity, and parents and adolescents perceive virtual reality (VR) interventions as a promising approach to increasing physical activity levels and improving eating habits. VR is a tool that fits perfectly with contemporary adolescent culture, which is radically different from that of just two generations ago. It is plausible that an XR-based intervention for treating adolescents with obesity could have a profound influence on obesity management over the long-term. An understanding of adolescents’ preferences, wants, and needs must be considered in the development of new interventions. We suggest that VR interventions can provide a new approach to weight management for children and adolescents and provide recommendations to assess adolescents’, caregivers’, and primary care providers’ needs. These needs could then be used for the development of an XR-based intervention aimed at inducing sustained lifestyle changes in adolescents with obesity.

Abstract
Excess sugary drink (SD) consumption is associated with childhood obesity and development of cardiometabolic disease. In addition to having high added sugar content, many SDs also contain caffeine, which may further encourage excess SD consumption among children. The objective of this study was to develop a conceptual framework of children's caffeinated SD consumption using group concept mapping, an applied social research multimethodology that collectively harnesses qualitative and quantitative data from participants to generate a visual representation of their ideas and input. Children, 8–14 years old, who reported consuming ≥12 ounces of caffeinated SDs (e.g., sodas, sweet teas) per day were recruited throughout Washington, D.C. and invited to participate. Concept mapping included three participant-driven activities: (1) brainstorming (n = 51), during which children reported reasons for their SD consumption, from which 58 unique reasons were identified; (2) sorting (n = 70), during which children sorted each of the reported reasons into categories and named each category; and (3) rating (n = 74), during which children rated the influence of each reason on their own caffeinated SD consumption. Similarity matrices, multidimensional scaling, and hierarchical cluster analysis were used to generate concept maps (hereafter “SODA MAPS”), which display the 58 reasons organized within eight overarching clusters. Among these eight clusters, Taste and Feel, Something to Do, and Energy were rated as particularly influential. Children's caffeinated SD consumption is encouraged not only by the palatable taste and reported preferences for these beverages (e.g., Taste and Feel), but also by psychological (e.g., Mood and Focus), biological (e.g., Energy), social (e.g., Something to Do) and environmental reasons (e.g., Nothing Better Available). Thus, the SODA MAPS can inform the development of tailored, multi-level SD reduction interventions that incorporate strategies to address important and currently overlooked reasons for caffeinated SD consumption among children.

Abstract
CONTEXT Family-based lifestyle interventions are recommended for adolescent obesity treatment, yet the optimal role of parents in treatment is unclear. OBJECTIVE To examine systematically the evidence from prospective randomized controlled and/or clinical trials (RCTs) to identify how parents have been involved in adolescent obesity treatment and to identify the optimal type of parental involvement to improve adolescent weight outcomes. DATA SOURCES Data sources included PubMed, PsychINFO, and Medline (inception to July 2019). STUDY SELECTION RCTs evaluating adolescent (12-18 years of age) obesity treatment interventions that included parents were reviewed. Studies had to include a weight-related primary outcome (BMI and BMI z score). DATA EXTRACTION Eligible studies were identified and reviewed, following the Preferred Reporting for Systematic Review and Meta-Analyses guidelines. Study quality and risk of bias were evaluated by using the Cochrane Collaboration risk of bias tool. RESULTS This search identified 32 studies, of which 23 were unique RCTs. Only 5 trials experimentally manipulated the role of parents. There was diversity in the treatment target (parent, adolescent, or both) and format (group sessions, separate sessions, or mixed) of the behavioral weight loss interventions. Many studies lacked detail and/or assessments of parent-related behavioral strategies. In ∼40% of unique trials, no parent-related outcomes were reported, whereas parent weight was reported in 26% and associations between parent and adolescent weight change were examined in 17%. LIMITATIONS Only RCTs published in English in peer-reviewed journals were eligible for inclusion. CONCLUSIONS Further research, with detailed reporting, is needed to inform clinical guidelines related to optimizing the role of parents in adolescent obesity treatment.

Abstract
PURPOSE We aimed to examine the prevalence of obesity among adolescents living in a refugee camp in Jordan and analyze the factors influencing their weight perceptions. DESIGN Cross-sectional survey. METHODS We examined the body weight perception, and the influence of psychological, cultural, and social factors, among Palestinian refugee adolescents living in Jordan using a cross-sectional survey. Univariate, bivariate, and multiple logistic regression analyses were used to investigate the relationships between body weight status, weight perception, satisfaction with weight, screen time, and depression status of these adolescents. RESULTS A total of 620 adolescents participated in the study, of which 24% were either overweight or obese. Overweight or obese adolescents were more likely to underestimate their weight (p < .001), while those with depressive symptoms (Patient Health Questionnaire for Adolescents score > 14), were more likely to overestimate their body weight (p = .021). Having symptoms indicative of depression (adjusted odds ratio [AOR] = 1.70; 95% confidence interval [CI] = 1.16-2.50) and having a body mass index in the overweight/obese range (AOR = 4.16; 95% CI = 2.73-6.35) were predictors of discordant weight perception. CONCLUSIONS This study showed that excess body weight is a significant issue among Palestinian refugee adolescents living in a refugee camp in Jordan. Underlying depression is an important factor in excess weight and distorted weight perceptions especially among this vulnerable group. CLINICAL RELEVANCE The study highlights the importance of addressing discordant body weight perception and depression in weight management in nursing interventions for vulnerable adolescent groups.

Abstract
Background/aim To determine risk factors of overweightness/obesity in children aged 0-5 years in the Turkish population. Materials and methods We made advanced analysis using the Turkey Demographic Health Survey (TDHS) 2013 female database, in which data from children aged under five years and their mothers are included. Analyses were performed using weight for height index data. The children were divided into two groups by age as 0–23 months and 24–59 months. Results The analysis comprised 2196 children aged under 5 years. Several factors were associated with an increase in overweightness/obesity of children aged under 5 years. Overweight/obesity in children aged 0-23 months was associated with several factors such as age (12–23 months) (OR: 2.89 CI: 1.62-5.13), high birth weight (OR: 2.36 CI: 1.26-4.44), maternal obesity (OR: 2.09 CI: 1.33-3.27), and maternal smoking (OR: 2.07, CI: 1.28-3.33). Overweightness/obesity in children aged 24–59 months was associated with several factors such as education level of the mother (OR: 2.27, CI: 1.08-4.75), consanguineous marriage (OR: 2.86, CI: 1.83-4.47), and which region of Turkey the family lives in (OR: 2.79, CI: 1.53-5.08). Conclusion Our results from the TDHS 2013 showed several risk factors of children overweight/obesity. Determining obesity risk factors, monitoring obese children/adults, and providing a multidisciplinary approach to the treatment and prevention of obesity will be useful for the future.

Abstract
Participation in physical activities benefits individuals with disabilities in terms of addressing their social and psychological needs in order for the purposes of quality living. This study reports the findings from a case study conducted with a boy who has Duchenne muscular dystrophy (DMD) in a swimming pool located in the campus of a private university in North Cyprus. The current study reports the adjustments made in the swimming pool in accordance with the needs of the participant, how service quality was increased to cater for these needs and in what ways the participant benefited from the aquatic program. This qualitative investigation aims to shed light onto how aquatic therapy has affected the boy with DMD physically, psychologically, and socially from the parents’ perspectives. The results revealed that aquatic therapy had beneficial effects on the participant with DMD in terms of socialization, relaxation, quality of life and self-perception.

Abstract
BACKGROUND Overweight and low levels of physical activity (PA) in preschoolers are major public health concerns. However, to date only few studies have investigated subjective and objective correlates of PA across different socioecological domains in preschoolers. We therefore simultaneously investigate associations between preschoolers' objectively measured leisure-time PA and a comprehensive set of subjective and objective potential PA correlates across the behavioral, social and physical environmental domains on both family- and community-level. METHODS In this cross-sectional study time spent in moderate-to-vigorous PA (MVPA) and total PA (TPA) were measured by combined accelerometry and heart rate monitoring in 735 3-6 year-old children from 52 preschools in Southern Germany. Family- and community-level potential correlates of PA from different domains (behavioral, social and physical environmental) were subjectively (i.e. by parent proxy-report) and objectively assessed. Their associations with PA on weekend days and weekday afternoons were tested by covariate-adjusted multilevel regression models. RESULTS While none of the objective social and physical environmental factors showed associations with PA, subjective parental traffic safety perceptions were positively associated with MVPA and TPA on weekends. Also, preschoolers' participation in organized sports was positively correlated with MVPA (on weekends) and TPA (both on weekends and weekday afternoons). CONCLUSION Subjective traffic safety perceptions and participation in organized sports, an indicator and a result of parental support towards PA - i.e. subjective parental perceptions of environmental factors and family-level correlates which are more proximal to preschoolers - might be more central to PA in preschool age than objectively assessed community-level environmental features which tend to be more distal correlates. If replicable, targeting parental perceptions of environmental factors and parental support for PA in preschool age might be powerful leverages for public health policy.

Abstract
Objectives This study assessed fruit and vegetable (F&V) waste during school meals in two public elementary schools, and investigated the impact of a tasting intervention implemented in one of these schools. Methods F&V waste was evaluated before (baseline), immediately after (post-testing), and six weeks following (follow-up), the tasting intervention. Results The modal outcome at each assessment was that children ate all of the served F&Vs. During tastings, most children attempted and liked the offered F&Vs. No differences between schools in F&V waste were evident at post-testing; at follow-up, the intervention school had significantly less F&V waste than the control school. Conclusions Generally, students were consuming the F&Vs served. Policy impact might be enhanced via a low-intensity tasting intervention.

Abstract
Many cross-sectional analyses and longitudinal studies have examined the association between adiposity and pubertal development. In addition, the impact of an increased fat mass on reproduction and fertility in human obese men and in male animal models of obesity has been studied. A trend toward earlier pubertal development and maturation in both sexes has been shown, and the notion that obese boys might progress to puberty at a slower pace than their nonobese peers can no longer be substantiated. Impaired fertility markers and reduced reproductive functions have been observed in obesity. Obesity affects both pubertal development and fertility in men.

Abstract
INTRODUÇÃO: A impedância bioelétrica (BIA) tem sido bastante utilizada para o monitoramento da composição corporal em indivíduos de diferentes idades e estados nutricionais. Entretanto, não se sabe qual das equações propostas para crianças e adolescentes é a mais recomendada para utilização em adolescentes com excesso de peso. Objetivo: Verificar a concordância dos métodos de BIA usando três equações diferentes com a absorciometria de raio-X de dupla energia (DXA), para análise da composição corporal de adolescentes com sobrepeso e obesidade.MÉTODOS: Participaram do estudo 27 adolescentes do sexo feminino, com sobrepeso e obesidade. Foram avaliados o percentual de gordura corporal (%GC), a massa gorda (MG) e a massa livre de gordura (MLG) por DXA e por BIA utilizando as equações propostas por Houtkooper, Schaefer e Deurenberg. ANOVA oneway, gráficos de Bland-Altman e o coeficiente de correlação intraclasse foram utilizados para comparação e verificação da concordância entre os métodos.RESULTADOS: A BIA utilizando a equação proposta por Houtkooper foi a única que não apresentou diferença estatística significativa na estimativa de %GC, MG e MLG em comparação ao DXA e apresentou boa concordância com o DXA na estimativa de %GC (-1,9 ± 3,29%), MG (1,5 ± 2,59 kg) e MLG (1,4 ± 2,60 kg), bem como boa reprodutibilidade para %GC (CCI = 0,81), MG (0,96) e MLG (0,89). As equações de Schaefer e de Deurenberg apresentaram menor concordância com o DXA, superestimando a MG e subestimando a MLG e apresentaram reprodutibilidade de moderada a baixa na maioria das medidas da composição corporal.CONCLUSÃO: Quando comparamos as três equações propostas para BIA com o DXA, verificamos que a equação proposta por Houtkooper foi a que melhor concordou com DXA e apresentou boa reprodutibilidade para estimar %GC, MG e MLG em adolescentes com sobrepeso e obesidade.

Abstract
BACKGROUND Body mass index (BMI) is the most widespread and the simplest method for the evaluation of body mass; it is often used as a sole technique in the diagnosis of obesity in children. The objective of the study was to evaluate the relationship between anthropometric and biochemical parameters and the incidence of the metabolic syndrome in obese children. METHODOLOGY A total of 110 children, aged 2-17 years, participated in the study. No overweight children (BMI 85-95 percentiles) were included. BMI was interpreted using the 2000 Centers for Disease Control and Prevention Growth Charts. The skinfold measurements were performed using an John Bull British Indicators Ltd. calipers, and interpreted using an the reference table values. RESULTS In addition to lower sensitivity (mentioned in several earlier studies), BMI also shows a lower specificity in the diagnosis of obesity in children: BMI showed at least 10% of non-concomitance with skinfold thickness and waist circumferences and 8% with waist-to-height ratio. In addition, subscapular skinfold thickness, waist circumference, and waist/height ratio showed stronger correlations with serum insulin levels, low-density lipoprotein cholesterol, and family history than BMI itself. CONCLUSION The unreliability of BMI as the sole parameter for diagnosing obesity in children was found in our study. Even when overweight children were excluded from the study, the lack of specificity of BMI was demonstrated. We propose utilization of waist circumference and waist/height ratio along with the BMI for definitive diagnosis instead of relying on BMI only. In addition, waist circumference and subscapular fold thickness may be even better in estimation of metabolic risk than BMI.

Abstract
AIM Obesity is known to be associated with many diseases in the long and short terms. Elevated oxidative stress contributes to the development of such obesity-related diseases as dyslipidemia, diabetes mellitus and hypertension. Levels of the endogenous antioxidants paraoxonase and arylesterase have been shown to decrease in such diseases. The purpose of this study was to investigate whether or not changes in lifestyle and metformin therapy would affect serum paraoxonase and arylesterase levels. MATERIALS AND METHODS The study was performed with 25 overweight, 26 obese and 25 morbidly obese patients aged 6-15 years as well as 27 healthy children. Serum paraoxonase (PON1) and arylesterase (ARE) activity levels and total cholesterol, triglyceride, low-density protein, high-density protein, very low-density protein, glucose, aspartate amino transferase and alanine amino transferase levels were measured. Enrolled patients were assessed at initial presentation and again at 6 months. No procedure was performed in the control group, while the overweight, obese and morbidly obese groups were recommended diet and exercise and given metformin therapy (insulin-resistant subjects only). RESULTS Serum PON1 activity levels in patients with metabolic syndrome were significantly lower than those in individuals without metabolic syndrome (p<0.05), while lipid concentrations were significantly higher (p<0.05). Metabolic syndrome patients had higher serum glucose, total cholesterol, low-density protein, very low-density protein and triglyceride values compared to those of the control group but significantly lower high-density protein values (p<0.05). No difference was determined between the groups in terms of PON1 and ARE levels following diet and exercise and metformin therapy. CONCLUSION Measurement of PON1 and ARE enzyme levels may be useful in monitoring the effectiveness of treatment aimed at reducing oxidative stress in obese children.

Abstract
OBJECTIVE To assess the prevalence of low body weight/thinness, overweight and obesity in a representative sample of children and adolescents from a Brazilian region with low economic development. METHODS A total of 982 girls and 986 boys, aged seven to 17 years old and assisted by Segundo Tempo Program, from Montes Claros, Minas Gerais, Brazil, were included in the study. Low body weight/thinness, overweight and obesity were defined based on body mass cut-off indexes recommended by the International Obesity Task Force. The prevalence of the nutritional status according to sex and age was compared by chi-square test. RESULTS In girls, the frequency of low body weight/thinness, overweight and obesity was 4.1, 18.4 and 3.8%, respectively; in boys, these percentages were 6.3, 13.2 and 2.9%, respectively. The low body weight/thinness for girls raised from 2.7% (7-10 years old) to 5.5% (15-17 years old); the body weight excess (overweight and obesity) decreased from 30.1 to 16.2% for the same age groups. In boys, the corresponding trends were from 3.2 to 9.4% for low body weight/thinness, and from 23.4 to 9.2%, for body weight excess. CONCLUSIONS The data indicate that, even in a region with low economic status, the body weight excess was the main problem associated with nutritional health. The high overweight and obesity prevalence rates indicate the need of public policies for promoting healthy feeding behaviors and physical activity.

Abstract
Background Well documented diversity in risk of developing overweight and obesity between children of immigrant and of native mothers, might be explained by different body mass index (BMI) development trajectories in relation to maternal and perinatal characteristics of offspring. Objectives To assess BMI development trajectories among children born to immigrant and to Swedish mothers from birth to adolescence in relation to perinatal characteristics. Methods A cohort of 2517 children born in Stockholm during 1994 to 1996 was followed with repeated measurement of height and weight at eleven time points until age 12 years. We estimated changes over time for BMI in relation to maternal and perinatal characteristics of offspring using mixed linear model analysis for repeated measure data. Results We observed a significant BMI change over time in children and time interaction with maternal migration status (P<0.0001). Estimated BMI over time adjusted for maternal and perinatal characteristics of offspring, showed slower BMI growth before age of 5, followed by an earlier plateau and steeper BMI growth after 5 years among children of immigrant mothers compared with children of Swedish mothers. These differences in BMI growth were more prominent among children with mothers from outside Europe. Conclusion Beside reinforcing early childhood as a crucial period in development of overweight, the observed slower BMI development at early childhood among children of immigrants followed by a steeper increase in BMI compared with children of Swedish mothers is important for further studies and for planning of preventive public health programs.

Abstract
PURPOSE Comprehensive multidisciplinary weight management programs encompassing various conservative measures have shown only modest weight loss results in obese children and adolescents; therefore, bariatric surgery for this population has become a matter of discussion. This study aimed to present our experience with and outcomes for laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in morbidly obese Korean adolescents. MATERIALS AND METHODS The prospectively established database of all patients undergoing bariatric surgery at Soonchunhyang University Seoul Hospital, Korea between January 2011 and January 2013 was retrospectively reviewed. Adolescents aged 14 to 20 years were included in the present analyses. RESULTS Twenty-two adolescents underwent bariatric surgery during the study period; 14 underwent LSG and 8, LRYGB. Of these, 17 were female and 5 were male. The mean age was 19 years. Their mean body weight and body mass index (BMI) before surgery were 115 kg and 40.1 kg/m². The only postoperative complication was intraluminal bleeding in 1 patient, which was managed conservatively. The mean BMI decreased to 29.1 kg/m² after a mean follow-up of 10 months. The percent excess weight loss (%EWL) at 1, 3, 6, and 12 months postoperatively were 19.6, 39.9, 52.6, and 74.2%, respectively. Only 1 patient showed %EWL less than 30% at 12 months after surgery. All patients with diabetes and sleep apnea were cured of their disease, and other comorbidities also improved or resolved after surgery. CONCLUSION Bariatric surgery leads to significant short-term weight loss along with resolution of obesity-related comorbidities in obese children and adolescents.

Abstract
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.

Abstract
Objectives: To assess the effectiveness of school-based interventions program in reducing the prevalence of overweight or obesity among schoolchildren. Data source: Ovid Medline (1950-December 2012), Embase (1980-2012), CINAHL (1982-2012), secondary references, review articles, and expert in the field. Study selection: All published clinical trials were eligible for study if were randomized, methodologically strong-based on a validity assessment, aimed to evaluate a school-based intervention for childhood overweight or obesity, and measured outcome in term of prevalence/incidence difference in overweight and obesity among both groups. Studies involved in cost-effective analysis of school-based intervention have been excluded. Data from eligible studies abstracted and pooled for relative risk. Results: Five trials with 3,904 schoolchildren were included. Mean age of the students (boys and girls) ranges 8.6-12.6 years. Meta-analysis showed a statistical significance beneficial effect of school-based intervention programs on obesity status of schoolchildren (risk ratio (RR) 0.58, 95% confidence interval (CI) 0.43-0.78) and suggested 42% reduction in prevalence of obesity among schoolchildren through school-based intervention programs. Individual studies also showed effectiveness of these school-based interventions. Conclusion: School-based intervention programs are effective in prevention of childhood overweight and obesity problem and our results quantitatively supported this argument.

Abstract
There is an urgent need for innovative approaches to pediatric obesity treatment. There is also a demand for targeted strategies that reduce attrition and improve treatment adherence. Intervening exclusively with parents of overweight children is a novel approach with demonstrated efficacy in reducing child body mass index (BMI) percentile. Motivational interviewing (MI), a brief communication style for exploring and resolving ambivalence about behavior change, might enhance treatment engagement when implemented as part of obesity interventions. The aim of this report is to provide the rationale and methods for a novel study of MI with parents in the treatment of their children's overweight. We designed and are currently implementing NOURISH+MI, a randomized controlled trial examining the feasibility and efficacy of an adjunct values-based MI intervention, implemented within a culturally-tailored parent intervention for overweight children ages 5-11 years, NOURISH(+) (Nourishing Our Understanding of Role modeling to Improve Support and Health). Specifically, we are randomly assigning 60 parents to this adjunctive treatment, and investigating if adding two MI sessions prior to the NOURISH(+) group intervention will enhance treatment effects. We will be able to compare NOURISH+MI participants with those from the two NOURISH(+) treatment conditions (NOURISH(+) and control). We hypothesize that children whose parents participate in NOURISH+MI will demonstrate lower attrition and greater adherence with NOURISH(+), ultimately leading to greater treatment effects, compared with children whose parents are randomized to NOURISH(+) or a control group. Findings will contribute to the emerging literature examining the efficacy of MI within pediatric obesity interventions.

Abstract
The process of pubertal development is only partly understood and is influenced by many different factors. During the twentieth century there was a general trend toward earlier pubertal development. Fat mass is thought to be a major inducer of puberty. Owing to the rising epidemic of childhood obesity, the relationship between body composition in children and the rate and timing of puberty needs to be investigated. Some studies suggest that central obesity is associated with an earlier onset of pubertal development. Rapid weight gain in early life is linked to advanced puberty in both sexes. A clear correlation exists between increasing body mass index (BMI) and earlier pubertal development in girls. In boys the data are controversial: The majority of studies propose that there is an earlier puberty and voice break in obese boys, but some studies show the opposite. There are several factors and mechanisms that seem to link obesity and puberty, for example, leptin, adipocytokines, and gut peptides. Important players include genetic variation and environmental factors (e.g., endocrine-disrupting chemicals). This article presents the latest studies and evidence on this topic, underlining the inconsistencies in the data and, therefore, the need for further research in this area.

Abstract
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.

Abstract
This study investigates parents' ability to correctly classify their child's weight status. The influence of parent and child socio-demographic and lifestyle factors on parental misclassification of their child's weight status is explored. A representative sample of Irish children (aged 5-12 (n = 596) years, aged 13-17 years (n = 441)) and their parents (n = 1885) were recruited to participate in a national dietary survey. Parental perceptions of their child's weight and their own weight were measured. Anthropometric measurements (weight and height) were objectively measured for parents and children. Body Mass Index (BMI) scores were derived and categorised as normal, overweight or obese using standard references. Over 80% of parents of overweight boys and 79.3% of parents of overweight girls reported their child's weight was fine for his/her height and age. Furthermore, 44.4% of parents of obese boys and 45.3% of parents of obese girls felt their child's weight was fine for their height and age. Parents were significantly less likely to be correct about their sons' weight status and more likely to be correct the older the child. Parents were over 86% less likely to be correct about their child's weight if their child was overweight and approximately 59% less likely to be correct if the child was obese, compared to parents of normal weight children. This research suggests that parents are failing to recognise overweight and obesity in their children with factors such as parental weight status, child's age and gender influencing this.

Abstract
A relationship between blood pressure (BP) and obesity has been found in young adults, but no data are available for adolescents in Kuwait. 257 adolescent (11-19 years) participants were categorized into two groups according to their BMI; 48 nonobese (21 males: 43.7% and 27 females: 56.3%) with mean age of 15.61 ± 2.40 years and 209 obese (128 males: 61.25% and 81 females: 38.75%) with mean age of 15.02 ± 2.82 years. The mean BMI was 21.7 ± 2.23 kg/m(2) for the nonobese group and 34.47 ± 4.70 kg/m(3) for the obese group. Most BP measures based on a single screening were significantly higher in the obese group. The prevalence of elevated BP was significantly higher in the obese subjects (nonobese: 13%; obese: 63%; P < 0.0001). In the obese group, there was a significant positive correlation between total sample BMI and all BP measures except the pulse pressure. There was a similar rate of elevated blood pressure between males and females (64% versus 60%; P = 0.66). For both isolated systolic elevated BP and isolated diastolic elevated BP, the prevalences were comparable between the males (systolic: 42%; diastolic: 5%) and females (systolic: 34%; diastolic: 14%). Only systolic BP was positively correlated with BMI in obese adolescent males (Spearman r = 0.18; P < 0.05), with a significant correlation between BMI with diastolic (Spearman r = 0.22; P < 0.05) and mean BP (Spearman r = 0.21; P < 0.05) in females.

Abstract
PURPOSE To describe the demographics, medical diagnoses, and initial aerobic fitness levels of children participating in Fitkids: an exercise therapy program for children with chronic conditions or disabilities in the Netherlands. METHODS We reviewed data of children who were in the program on September 2010. RESULTS In total, 2482 children from 105 Fitkids centers were included. Results showed the large heterogeneity of the population regarding demographic characteristics and medical diagnoses. Significantly reduced scores on the 6-minute walk test and half Bruce treadmill test were observed. CONCLUSION The Fitkids population has great heterogeneity. In addition, a plethora of fitness tests were used, and registration of data in the Fitkids database was suboptimal. Moreover, this study showed the impaired aerobic fitness of children participating in Fitkids. Future research should investigate the effectiveness of the Fitkids program.

Abstract
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.

Abstract
OBJECTIVES The objectives of this study were to (i) compare the strength of associations between sleep duration and body mass index (BMI) in middle childhood, and early and late adolescence; (ii) determine whether sleep duration in middle childhood predicts BMI in early or late adolescence; and (iii) examine the consistency of these associations by sex. METHODS Subjects included 313 children/adolescents aged 8-19 participating in a longitudinal cohort study on sleep and health. Participants were assessed at three time points approximately 4 years apart: ages 8-11, 12-15 and 16-19. BMI z-score (BMIz) was calculated using age and sex normative data from the Centers for Disease Control. Sleep duration was reported by the parent (ages 8-15) or the adolescent (ages 16-19). RESULTS [corrected] Half of the participants were male and 79% were Caucasian. Sleep duration had a negative linear association with BMIz for boys but not girls, and the magnitude of this association decreased with age. Sleep duration at age 8-11 predicted BMIz in early and late adolescence for boys but not girls, and associations were largely attenuated after adjusting for BMIz at age 8-11. The strongest predictor of adolescent BMIz was BMIz at age 8-11 for both boys and girls. CONCLUSION We conclude that the association between sleep duration and BMIz varies by sex and age, with stronger associations in boys and in middle childhood compared with adolescence.

Abstract
Puberty is a period of physical and psychological maturation, with long-term effects on health. During the 20(th) century, a secular trend towards earlier puberty occurred in association with improvements in nutrition. The worldwide pandemic of childhood obesity has renewed interest in the relationship between body composition in childhood and the timing and tempo of puberty. Limited evidence suggests that earlier puberty is associated with a tendency towards central fat deposition; therefore, pubertal status needs to be carefully considered in the categorization of childhood and adolescent overweight and obesity. In the other direction, rapid early weight gain is associated with advanced puberty in both sexes, and a clear association exists between increasing BMI and earlier pubertal development in girls. Evidence in boys is less clear, with the majority of studies showing obesity to be associated with earlier puberty and voice break, although a subgroup of boys with obesity exhibits late puberty, perhaps as a variation of constitutional delay in growth and puberty. The possible mechanisms linking adiposity with pubertal timing are numerous, but leptin, adipocytokines and gut peptides are central players. Other possible mediators include genetic variation and environmental factors such as endocrine disrupting chemicals. This Review presents current evidence on this topic, highlighting inconsistencies and opportunities for future research.

Abstract
BACKGROUND The Communities IMPACT Diabetes Center uses partnered methods to address diabetes-related conditions among African Americans and Latinos in East Harlem, New York. OBJECTIVES To describe a novel, partnered approach that integrates simultaneous structured observation by community and academic partners with "on-the-spot" resolution of differences to collect baseline data regarding the built and food environments in a two census tract area of East Harlem and present select findings. METHODS We designed an environmental assessment to explore characteristics of the environment related to walking and eating. We paired community and academic partners to assess each block, resolve any differences, and report results. Nearly one year later, we surveyed the data collectors and analyzed responses using standard qualitative methods. RESULTS Key themes included connection to and characteristics of the community; interactions with partners; surprises and learning, and aspects of data collection. All but the first were common to academic and community partners. Relationships between partners were generally amiable. Both community-"I think it was very helpful, we made sure neither of us made mistakes, and helped each other when we could"-and academic-"I really enjoyed it . . . I learned a lot about the areas I surveyed"-partners were complimentary. Community partners' strengths included local knowledge of the community, whereas academic partners' focus on adherence to the specifications was critical. Structured observation identified many sidewalks in disrepair or obstructed, few benches, and highly variable times allocated for pedestrians to cross at cross walks. CONCLUSIONS The partnered data collection was both successful and formative, building additional relationships and further capacity for ongoing partnership. Community partners saw their community in a new way, seeing, "little things that are important but people don't pay attention to." Structured observations added to our understanding of how an environment may contribute to diabetes.

Abstract
Silhouette measures are one approach to assessing body dissatisfaction in children, although little is known about their use among racially diverse, overweight girls seeking weight-loss treatment. This study assessed racial differences in body dissatisfaction and body size perceptions of 58 girls (ages 6-11, 66% Black, 34% White) participating in a randomized trial for pediatric overweight. Body dissatisfaction did not differ between races; 99% of girls reported an ideal figure smaller than their current one. Black girls selected a larger silhouette to represent their ideal body size, and most girls in both racial groups underestimated their actual size. Outcomes strengthen the argument that, despite an overall preference for a larger body size, obesity might mitigate cultural factors that protect Black girls from body dissatisfaction. Additional research is needed to enhance understanding of children's body size perceptions and dissatisfaction to inform assessment and treatment of pediatric obesity and associated disordered eating symptoms.

A high-fat diet reduces ceramide synthesis by decreasing adiponectin levels and decreases lipid content by modulating HMG-CoA reductase and CPT-1 mRNA expression in the skin. Mol Nutr Food Res 2011; 55 Suppl 2:S186-92. [PMID: 21732532 DOI: 10.1002/mnfr.201100144] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2011] [Revised: 04/22/2011] [Accepted: 05/06/2011] [Indexed: 11/05/2022]
Abstract
SCOPE Molecules involved in skin function are greatly affected by nutritional conditions. However, the mechanism linking high-fat (HF) diets with these alterations is not well understood. This study aimed to investigate the molecular changes in skin function that result from HF diets. METHODS AND RESULTS Sprague-Dawley rats were fed HF diets for 28 days. The skin levels of ceramide, lipids and mRNAs involved in lipid metabolism were evaluated using TLC, oil red O staining and quantitative PCR, respectively. The serum adiponectin concentration was determined by ELISA. HF diets led to reduced ceramide levels and lowered skin lipid content. They also decreased mRNA levels of serine palmitoyltransferase (SPT) and 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase in the skin and those of peroxisome proliferator-activated receptor-α -PPAR-α), which upregulates SPT and HMG-CoA reductase expression. The HF diets reduced the serum concentration of adiponectin, which acts upstream of PPAR-α. Finally, these diets led to increased mRNA levels of carnitine palmitoyltransferase-1, the rate-limiting enzyme that acts in β-oxidation. CONCLUSION Our study suggests that HF diets reduce ceramide and lipid synthesis in the skin by reducing levels of SPT and HMG-CoA reductase through lowered adiponectin and PPAR-α activity. Additionally, they decrease lipid content by enhancing β-oxidation.

Abstract
BACKGROUND The objective of this study was to measure the validity and reliability of a multifactorial Risk Factor Model developed for use in predicting future caries risk in Nevada adolescents in a public health setting. METHODS This study examined retrospective data from an oral health surveillance initiative that screened over 51,000 students 13-18 years of age, attending public/private schools in Nevada across six academic years (2002/2003-2007/2008). The Risk Factor Model included ten demographic variables: exposure to fluoridation in the municipal water supply, environmental smoke exposure, race, age, locale (metropolitan vs. rural), tobacco use, Body Mass Index, insurance status, sex, and sealant application. Multiple regression was used in a previous study to establish which significantly contributed to caries risk. Follow-up logistic regression ascertained the weight of contribution and odds ratios of the ten variables. Researchers in this study computed sensitivity, specificity, positive predictive value (PVP), negative predictive value (PVN), and prevalence across all six years of screening to assess the validity of the Risk Factor Model. RESULTS Subjects' overall mean caries prevalence across all six years was 66%. Average sensitivity across all six years was 79%; average specificity was 81%; average PVP was 89% and average PVN was 67%. CONCLUSIONS Overall, the Risk Factor Model provided a relatively constant, valid measure of caries that could be used in conjunction with a comprehensive risk assessment in population-based screenings by school nurses/nurse practitioners, health educators, and physicians to guide them in assessing potential future caries risk for use in prevention and referral practices.

Abstract
The incidence of childhood obesity ranges today from approximately 8% to 17%, and is an increasing issue in developed and developing countries. This disease will become increasingly significant in paediatric anaesthesia. Obese children not only have anaesthesia-relevant co-existing diseases, that are, asthma and hypertension, but also have a higher incidence of anaesthesia-related complication. This review covers current definition and some epidemiology of childhood obesity. It summarises potential co-morbidities and provides details for preoperative evaluation, anaesthetic management and prevention of perioperative complications.

Contemp Clin Trials 2011; 32:667-74.

Abstract
To reduce pediatric obesity in clinical settings, multidisciplinary behaviorally-based treatment programs are recommended. High attrition and poor compliance are two difficulties frequently encountered in such programs. A brief, empathic and directive clinical intervention, Motivational Interviewing (MI), might help address these motivational and behavioral issues, ultimately resulting in more positive health outcomes. The efficacy of MI as an adjunct in the treatment of pediatric obesity remains relatively understudied. MI Values was developed to implement within an existing multidisciplinary treatment program for obese, ethnically diverse adolescents, the T.E.E.N.S. Program (Teaching, Encouragement, Exercise, Nutrition, Support). T.E.E.N.S. participants who consent to MI Values are randomized to either MI or an education control condition. At weeks 1 and 10 of T.E.E.N.S. participation, the subset of participants assigned to the MI condition engages in individual MI sessions and control participants view health education videos. All MI sessions are audiotaped and coded to monitor treatment fidelity, which has been satisfactory thus far. Participants complete comprehensive assessments at baseline, 3- and 6-month follow-ups. We hypothesize that MI participants will demonstrate greater reductions in Body Mass Index (BMI) percentile, improved diet and physical activity behaviors, better compliance with T.E.E.N.S., and lower attrition than participants in the control group. We present study design and methods for MI Values as well as data on feasibility of recruitment methods and treatment integrity. At study completion, findings will contribute to the emerging literature examining the efficacy of MI in the treatment of pediatric obesity.

Abstract
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 were obtained from records of 118 patients, ages 8 to 18, seen in a multidisciplinary pediatric pain clinic. Information about age, sex, 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 with 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.

Abstract
Although it is known that nutritional conditions affect the skin function, little information is available on the effect of a high-fat (HF) diet on skin. In this study, Sprague-Dawley rats were fed HF diets for 28 days, and we investigated the effect of this diet on type I tropocollagen and hyaluronan in rat skin. The HF diets reduced the levels of type I tropocollagen, COL1A1 mRNA, hyaluronan, and rat hyaluronan synthase (rhas)2 mRNA, which play a primary role in hyaluronan synthase in the dermis. However, rhas3 mRNA level in the skin was increased. The HF diets also decreased the skin mRNA expression of transforming growth factor (TGF)-beta1, which enhances the expression of COL1A1 and rhas2 mRNA and decreases rhas3 mRNA expression, and decreased the hepatic mRNA expression of insulin-like growth factor (IGF)-I, which enhances COL1A1, rhas2, and TGF-beta1 mRNA expression. The serum level of adiponectin, which promotes the syntheses of type I collagen and hyaluronan, was decreased in the HF diet groups. These findings suggest that an HF diet reduces the levels of type I tropocollagen and hyaluronan in the skin by suppressing the action of TGF-beta1, IGF-I and adiponectin, and these effects are deleterious for skin function.

Abstract
Short sleep duration and obesity are common health concerns in youth. This study of South Korean adolescents explores the association between the two conditions analyzing secondary data from the 2007 Korea Youth Risk Behavior Web-Based Survey. The sample is representative of the South Korean adolescent population ( N = 73,836). For data analysis, analysis of variance, chi-square test, and logistic regression were used. Findings indicated that (a) sleep duration is inversely associated with levels of body mass index, F(4, 72654) = 240.07, p < .0001, and risks for overweight and obesity, χ2(4, 72659) = 27.41, p < .0001; and (b) after controlling for obesity-related factors, reduced sleep is strongly associated with a greater risk for overweight and obesity, OR = 0.94, p < .0001. Given the important link between sleep and obesity, health professionals should consider sleep habits as a significant factor in obesity-related problems of youth.
