Abstract
Introduction After 2000, there are more obese than underweight people in the world. We face a rapid increase in average global warming of 1.5°C, reported as a syndemic problem of three interconnected epidemics: obesity, global warming, and undernutrition. We aimed to analyze the impact and association between global warming and obesity in children and differences by gender across Europe after 2000. Methods We searched PubMed, MEDLINE, Google Scholar, ScienceDirect, and Embase databases. The considered population were children aged 6-14. Only cross-sectional studies that defined obesity by the IOTF cutoffs and the subjects' place of residence, used to determine precise climate zones, were included. We assessed the prevalence of obesity and overweight using a random-effects and the Mantel-Haenszel fixed-effect method when heterogeneity was greater/lower than 50%. We did a subgroup analysis for prevalence across gender, obesity, and overweight, two decades, regions, countries, and the Köppen-Geiger climate zones. Random effects of the meta-regression were used to study the global warming impact and differences in trends across European countries by gender for both conditions separately. Results We identified 114 studies that included 985,971 children from 39 European countries. A significant difference between genders was in favor of obese girls 4.78 (95% CI: 3.85-5.93) versus boys 5.76% (95% CI: 5.11-6.48, p = 0.03), respectively, but not for overweight children. Most of the obese girls were in South Europe 7.51% (95% CI: 6.61-8.51) versus East Europe 2.86% (95% CI: 23-3.12), versus boys in South Europe 8.66% (95% CI: 7.68-9.74) and North Europe 3.49% (95% CI: 2.90-4.19), respectively. The "cold" Köppen-Geiger climate zone, with lowest temperatures, has the largest trend rise between two decades of 2.8% and 1.53% for obese girls and boys, and 5.31% and 1.81% for overweight girls and boys, respectively, followed by the smallest number of obese girls 3.28% (95% CI: 2.17-4.92) and boys 3.58% (95% CI: 2.39-5.33), versus the zone with the highest temperatures "hot" for girls 7.02% (95% CI: 6.30-7.82) and for boys 8.23% (95% CI: 7.55-8.96), respectively. The meta-regression proved global warming has a significant impact on the distribution of obesity and overweight across climate zones, R2 = 0.52 and R2 = 0.22. No significant gender differences, or significant interaction, was noted. Conclusion Our meta-analysis provides a comprehensive overview of the association between and impact of global warming on obesity. This impact increases obesity among children in Europe throughout all climate zones, and emphasizes an urgent call for further preventive methods in schools, since obesity differences continue their trend of disappearing into the future.Systematic review registration: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021282127, identifier: CRD42021282127.

Abstract
PURPOSE Pituitary adenomas (PAs) rarely occur in childhood and adolescence. Management of PAs in this critical age can be particularly challenging considering the auxological sequelae and potential long-term cardiometabolic consequences. We aimed to describe the clinical characteristics of patients with PA aged < 18years at diagnosis and during long-term follow-up, focusing on the prevalence of cardio-metabolic comorbidities and the impact of different therapeutic strategies. METHODS Clinical data at diagnosis and at last follow-up visit (mean 10.3 ± 9.2 years) of 101 patients aged < 18 years with PA, referred to our University Hospital from 1990 to 2017, were retrospectively evaluated. RESULTS At diagnosis, 11.9% of patients presented with pituitary hormone deficiencies, whose number was positively correlated with pituitary tumor diameter (p < 0.001). At diagnosis, 26.7% of patients were overweight and 15.8% were obese. In patients with hypercortisolism or GH excess the prevalence of obesity was more than 2-fold greater than in general population. No correlation was found between pituitary tumor size and BMI. At baseline, the greater the number of pituitary hormone deficits, the higher BMI (p = 0.039). In prolactinoma patients still on medical therapy at last visit, BMI was higher than at baseline. CONCLUSION We found an increased prevalence of overweight/obesity only in pediatric and adolescent patients with GH- or ACTH-secreting PA. Regarding cardio-metabolic comorbidities other than obesity/overweight, we have not found anything worth of mention. The remission of hypercortisolism positively impacted on BMI, while medical therapy in patients with prolactinoma seemed unable to avoid weight gain, suggesting a careful metabolic management of these patients.

Impact of unhealthy childhood and unfavorable parents' characteristics on adiposity in schoolchildren. Diabetes Metab Res Rev 2019; 35:e3199. [PMID: 31257680 DOI: 10.1002/dmrr.3199] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Revised: 06/06/2019] [Accepted: 06/20/2019] [Indexed: 11/06/2022]
Abstract
BACKGROUND Childhood obesity is encouraged by low physical activity (PA), time spent using screens (screen time, ST), and by sugar-sweetened beverage consumption (SSBc). It is also influenced by unfavorable parents' characteristics, such as a high body mass index (BMI) and low education level (EL). Our aim was to evaluate the overall and specific influence of these factors on childhood adiposity. MATERIAL AND METHODS Anthropometric parameters including BMI z-score, waist circumference (WC), waist to height ratio (WtHR), and fat mass were measured in a cohort of 1702 schoolchildren (6.0-14.5 years, mean 10.7 ± 1.8) and questionnaires concerning children's PA, ST, and SSBc, and parent's BMI and EL were administered to parents. RESULTS Overweight/obesity prevalence was higher (P < .0001) in males (57%) than in females (43%). Less physically active children (28.9%) had a higher prevalence of overweight/obesity and higher BMI z-score, WC, WtHR, and fat mass relative to more physically active children (P < .05). PA was negatively associated with the BMI z-score (r = 0.18, P < .0001) and fat mass percentage (r = 0.18, P < .0001). Children with more ST had higher WC and WtHR than non-ST viewers (P < .05) but not BMI. Moreover, SSBc did not influence the anthropometric parameters. At multivariate analysis, male gender, less PA, and parental risk factors (parent's overweight/obesity and low/medium EL) were independently associated with overweight and obesity among childhood with a progressively increasing odds ratio (1.65, 1.40, and 1.80, respectively). CONCLUSIONS Male gender, behavioral risk factors (particularly low PA), and parent's characteristics are important correlates of obesity in children.

Abstract
PURPOSE We recently reported that a high BMI and high waist circumference prevalence is present in Sicilian children and that the male gender is associated with a significant risk of obesity. Early-life and parent-related risk factors were investigated 1521 Sicilian children (752 females and 769 males, aged 9.0-14.0 years) to identify biological and environmental factors that can contribute to obesity onset. METHODS Anthropometric measurements of children, their urban vs rural area provenience, birth weight and neonatal feeding were collected. In addition, the BMI and educational level of their parents and the perception of their child weight status were investigated. RESULTS In the study cohort, the prevalence of overweight and obesity was 27.2 and 14.1 %, respectively, significantly (p < 0.05) higher in males than in females. Breastfeeding emerged as a protective factor (OR 0.64; p < 0.0005), while risk factors for developing childhood obesity were a birth weight ≥4.0 kg (OR 1.83; p < 0.05), an overweight or obese mother (OR 2.33; p < 0.0001) or father (OR 1.68; p < 0.0001) and a mother with a low/medium education level (OR 1.72; p < 0.005). CONCLUSION Understanding risk factors for pediatric obesity is a prerequisite to identify children at highly risk of being obese and to predispose early intervention strategies.

Abstract
Objective. To review the extant literature on the prevalence of overweight and obesity in adolescents (10-19 years old) of both sexes. Design. The search was carried out using Medline and Scopus considering articles published from the establishment of the databanks until June 7, 2012. Data on the prevalence of children being overweight and obese from the International Obesity Task Force (IOTF) website was also reviewed. Only original articles and one National Health Report were considered. Forty studies met the inclusion criteria. Results. Twenty-five of these studies were nationally representative, and ten countries were represented only by regional data. Conclusions. The prevalence of overweight and obesity among adolescents worldwide is high, and obesity is higher among boys. The IOTF criterion is the most frequently used method to classify adolescents as overweighed or obese in public health research.

Abstract
OBJECTIVE The objective of the present study was to investigate the prevalences of overweight and obesity and their association with physical activity pattern among adolescents in northern Iran. DESIGN A cross-sectional study. SETTING Babol, northern Iran. SUBJECTS A representative sample of 1200 adolescents aged 12-17 years was recruited. All selected adolescents were interviewed, their leisure-time and sport physical activities were collected by a standard Baecke questionnaire and their height and weight were measured by standard methods. The diagnosis of overweight and obesity was determined by comparing BMI values with the BMI index for age and sex percentiles set by the US Centers for Disease Control and Prevention in 2000. RESULTS The prevalences of overweight and obesity were 15.1 % and 8.3 %, respectively. The proportion of obesity was significantly higher in boys than in girls (10.2 % v. 6.5 %, P = 0.028). Overall, the levels of high, moderate and low leisure-time physical activity were 2.9 %, 79.4 % and 17.7 %, respectively. The corresponding levels of high, moderate and low sport physical activity were 17.4 %, 75.2 % and 7.4 %. The levels of leisure-time and sport physical activities were significantly higher among the boys than the girls (P < 0.001). There was also a significant association of studying in private schools and playing computer games with overweight/obesity (P < 0.001). Moderate leisure-time physical activity was unexpectedly associated with a greater risk of overweight/obesity compared with the low level (P = 0.002). CONCLUSIONS The findings indicate a high prevalence of overweight/obesity in these Iranian adolescents, particularly the boys. The influence of physical activity and diet on overweight/obesity requires further prospective studies.

Abstract
The present study evaluates trends in the prevalence of overweight and obesity in relation to gender and area of residence between two cohorts of students aged 11–13 years in Sicily. The analysis was performed on 1,839 schoolchildren, with 924 and 915 children being studied in 1999–2001 and 2009–2010, respectively. The children who were enrolled during 2009–2010 had significantly higher body mass indexes (BMI), BMI z-scores, and waist circumferences than the children who were studied during 1999–2001 (p<0.0001 for all); these differences was also observed when the cohort was subdivided according to gender or residence area The prevalence of obesity increased significantly from 7.9% in 1999–2001 to 13.7% in 2009–2010 (p<0.0001), whereas thinness decreased significantly from 10.1% to 2.3% (p<0.0001) in the same periods. The increase of trends in the prevalence of obesity was significantly higher in males (9.7% vs. 17.6%, p = 0.0006) than in females (6.3% vs. 9.8%, p = 0.04) and was slightly higher in urban areas (8.8% vs. 14.3%, p = 0.002) than in rural areas (7.8% vs. 13.0%, p = 0.012). The male gender was associated with a higher risk of being overweight or obese (odds ratio: 1.63; 95% confidence intervals: 1.24–2.15; p = 0.0005) in 2009–2010 than in 1999–2001, after adjusting for age and the residence area. In conclusion, this study showed an increasing trend in the prevalence of overweight and obesity in Sicilian schoolchildren during the last decade and that this trend was related to gender, age and the area of residence. More specifically, our data indicated that the prevalence of obesity increased by 5.8%, the prevalence of thinness decreased by 7.8% and the prevalence of normal-weight children did not change over the course of a decade. These results suggest a shift in the body weights of Sicilian children toward the upper percentiles.

Abstract
OBJECTIVE To analyze the prevalence of the metabolic syndrome (MetS) defined by three sets of Adult Treatment Panel III (ATPIII)-derived criteria, and the ability of each definition to identify insulin-resistance (IR) in a wide cohort of outpatient children. SUBJECTS AND METHODS Seven hundred and twenty-four children consecutively observed in the Outpatient Pediatric Clinic of Pozzuoli Hospital during the period 2004-2009 were included in the study. Diagnosis of the MetS was made using three definitions: Cook, Jolliffe (which adopt age- and gender-specific cut-points) and de Ferranti. Insulin sensitivity was evaluated by homeostasis model assessment of insulin resistance (HOMA-IR). IR was defined by the 90th percentile of HOMA-IR in healthy non-obese Italian children grouped by gender and Tanner stage. The ability of each definition to identify IR was evaluated in terms of sensitivity and specificity. RESULTS The prevalence of the MetS in the overall cohort was 11, 12 and 24% using Cook, Jolliffe and de Ferranti criteria, respectively. Sensitivity and specificity in relation to IR were 19 and 94% with Cook criteria, 21 and 92% with Jolliffe criteria, and 39 and 84% with de Ferranti criteria. CONCLUSIONS The prevalence of the MetS in children increases with increasing body weight. Among the three definitions analyzed, de Ferranti identifies a larger number of children with the MetS. The prediction of IR is weak with all definitions; on the contrary, the absence of MetS identifies fairly well children with low degree of IR.

Abstract
OBJECTIVES Obesity and exposure to cardiovascular risk factors during adolescence may be associated with the development of atherosclerosis and cardiovascular diseases later in life. The objective of the study was to investigate whether any excess body weight, including moderate overweight, is associated with a more severe cardiovascular risk profile and signs of early atherosclerosis in a pediatric population. PATIENTS AND METHODS A cross-sectional study was conducted among 646 adolescents ages 11 to 13 years from several primary schools of Reggio Calabria, Italy. Body mass index, waist circumference, blood pressure, glucose, insulin, homeostatic model assessment of insulin resistance, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and C-reactive protein (CRP) were determined. All of the subjects underwent carotid ultrasonography for the measurement of intima-media thickness. Complete clinical data were available from 575 subjects. RESULTS Overweight was similarly frequent in boys and girls (31.2% vs 31.0%), whereas prevalence of obesity was higher in boys (18.4% vs 10.1%). Subjects with lower levels of HDL and higher levels of triglycerides, insulin, and CRP plasma were observed more frequently among overweight and obese subjects than nonoverweight. At multivariate analysis, HDL cholesterol, insulin, and CRP were associated (P < 0.05) with overweight and obesity in girls, whereas in boys, insulin and CRP were associated (P < 0.05) with overweight and obesity, and LDL cholesterol with obesity. The association between overweight or obesity and increased intima-media thickness, a sign of early atherosclerosis, was present in girls (P < 0.05) and was close to statistical significance in obese boys (P = 0.07). CONCLUSIONS Overweight and obese adolescents have a higher prevalence of cardiovascular risk factors and show signs of early atherosclerosis. In girls, in particular, overweight is sufficient to determine a more severe cardiovascular risk profile.

The objective of this study was to determine, in an adolescent population, the prevalence of nonalcoholic fatty liver disease (NAFLD) and the association of NAFLD and cardiovascular risk factors with carotid artery intima-media thickness (IMT), a marker of subclinical atherosclerosis. The authors conducted a population-based study among 642 randomly selected adolescents aged 11-13 years in Reggio Calabria, southern Italy, between November 2007 and October 2008. Prevalences of overweight and obesity were 30.5% and 13.5%, respectively. The overall prevalence of NAFLD was 12.5%, increasing to 23.0% in overweight/obese adolescents. In univariate analysis, increased IMT was positively associated with the presence of NAFLD, body mass index (BMI), waist circumference, systolic blood pressure (all P's < 0.001), diastolic blood pressure (P = 0.006), gamma-glutamyl transpeptidase (P = 0.006), alanine aminotransferase (P = 0.007), and C-reactive protein (P = 0.008) and was inversely associated with high density lipoprotein cholesterol (P < 0.001). In multivariate analysis, NAFLD (P = 0.002), BMI (P = 0.004), waist circumference (P = 0.003), and systolic blood pressure (P = 0.005) retained significant associations. The authors conclude that NAFLD, BMI, waist circumference, and systolic blood pressure are independent markers of increased IMT in a random sample of adolescents.

Abstract
Background This survey determined the practices about television (video inclusive), videogames, and computer use in children and adolescents in Italy. Methods A self-administered anonymous questionnaire covered socio-demographics; behaviour about television, videogames, computer, and sports; parental control over television, videogames, and computer. Results Overall, 54.1% and 61% always ate lunch or dinner in front of the television, 89.5% had a television in the bedroom while 52.5% of them always watched television there, and 49% indicated that parents controlled the content of what was watched on television. The overall mean length of time daily spent on television viewing (2.8 hours) and the frequency of watching for at least two hours per day (74.9%) were significantly associated with older age, always ate lunch or dinner while watching television, spent more time playing videogames and using computer. Those with parents from a lower socio-economic level were also more likely to spend more minutes viewing television. Two-thirds played videogames for 1.6 daily hours and more time was spent by those younger, males, with parents that do not control them, who watched more television, and who spent more time at the computer. The computer was used by 85% of the sample for 1.6 daily hours and those older, with a computer in the bedroom, with a higher number of computers in home, who view more television and play videogames were more likely to use the computer. Conclusion Immediate and comprehensive actions are needed in order to diminish time spent at the television, videogames, and computer.

Abstract
OBJECTIVES The aim of the present study was to identify the prevalence and non-nutritional correlates of childhood obesity in primary school children and adolescents living in a representative sample of an urban area in western Anatolia. METHODS The study was designed as a cross-sectional, population-based study. A representative sample of primary school children in Aydin was randomly selected according to age, gender and socio-economic status. Body mass index (BMI) was calculated after weight and height measurement. Centres for Disease Control 2000 growth charts for children and adolescents were used to identify BMI percentiles. Weight and height percentiles were obtained from charts of growth curves for Turkish children. RESULTS The age range of children was 6-16 years. A total of 924 children and 424 adolescents were screened for obesity. Overweight and obesity prevalence in primary school children living in Aydin was 12.2% and 3.7%, respectively. High socio-economic status was found to be associated with childhood obesity. There was no association between obesity and gender, adolescence, educational status of parents and occupation of father. CONCLUSION In the present study, we focused on some of the non-nutritional correlates of obesity in a representative population of an urban area in a developing country. Obesity prevalence rate in Turkish children living in Aydin was higher in children from a higher socio-economic group in contrast to reports from many developed countries.

Abstract
AIM The impact of central adiposity on left ventricular (LV) mass in childhood obesity has been little explored. This study evaluates whether central obesity influences LV mass and function in obese children. METHODS AND RESULTS Biochemical, anthropometric and echocardiographic measurements were taken in obese (n=111, mean age 10.6+/-2.5 years) and non-obese children (n=30, mean age 10.8+/-3.0 years). Left ventricular function was analyzed by conventional and tissue Doppler echocardiography. LV mass was calculated according to the Penn convention and indexed for height(2.7) (LVM(i)). The obese group showed increased levels of LVM(i) as compared to the non-obese group (35.7+/-8.5 vs 23.5+/-2.8 g/h(2.7), p<0.0001). Among obese children, we observed a significant increase of LVM(i) across tertile of waist-height ratio (WHtR). The subjects identified by the highest tertile of WHtR, as compared to subjects identified by the lowest tertile, showed higher levels of BMI (29.5+/-5.4 vs 31.0+/-5.0 kg/m(2), p<0.0001) and LVM(i) (32.1+/-6.5 vs 37.1+/-8.5 g/h(2.7), p<0.01). Among obese children a positive correlation (standardized for age and gender) was found between LVM(i) and BMI (r=0.282, p<0.01) and WHtR (r=0.334, p<0.0001). To analyze the independent predictors of LVM(i), a stepwise linear regression analysis was performed using age, gender, BMI, blood pressure, heart rate, HOMA-IR and WHtR as independent variables. LVM(i) was independently associated only with WHtR (beta=0.309, t=3.238, p=0.002). CONCLUSION Obese children show an increased LVM(i) and a preserved LV function. Central adiposity is the major determinant of left ventricular mass.

Abstract
The objective of this review is to determine the distribution of obesity by geographical location, income, age and sex in the Mediterranean region during the last decade. A meta-analysis was conducted for 102 articles cited during the period (1997-2007) in Medline database (for 17 Mediterranean countries) searched during the summer of 2007 using the word 'obesity' and its related keywords. The study showed that adults were more obese than children in all Mediterranean continents and in different levels of income. The prevalence of obesity among European children was higher than among Asians. Also, European adults were more obese than European children. The total female adults were found to be more obese (median: 25.3%) than male adults (median: 20.0%). The regression model analysis indicated that male adults were more likely to be obese in the Euro-Med region. Taking different factors into consideration, it was noticed that Mediterranean adults, especially those in the European region, are at higher risk of obesity. Awareness programmes addressing the importance of adopting healthy dietary habits combined with physical activity should target the whole community in general and adults in particular. The findings could guide health planners for better management of obesity.

Abstract
Background The literature on childhood and adolescent obesity is vast. In addition to producing a general overview, this paper aims to highlight gender differences or similarities, an area which has tended not to be the principal focus of this literature. Methods Databases were searched using the terms 'obesity' and 'child', 'adolescent', 'teenager', 'youth', 'young people', 'sex', 'gender', 'masculine', 'feminine', 'male', 'female', 'boy' and 'girl' (or variations on these terms). In order to limit the potential literature, the main focus is on other reviews, both general and relating to specific aspects of obesity. Results The findings of genetic studies are similar for males and females, and differences in obesity rates as defined by body mass index are generally small and inconsistent. However, differences between males and females due to biology are evident in the patterning of body fat, the fat levels at which health risks become apparent, levels of resting energy expenditure and energy requirements, ability to engage in certain physical activities and the consequences of obesity for the female reproductive system. Differences due to society or culture include food choices and dietary concerns, overall physical activity levels, body satisfaction and the long-term psychosocial consequences of childhood and adolescent obesity. Conclusion This review suggests differences between males and females in exposure and vulnerability to obesogenic environments, the consequences of child and adolescent obesity, and responses to interventions for the condition. A clearer focus on gender differences is required among both researchers and policy makers within this field.

Abstract
Overweight and obesity are an increasing problem: worldwide, for Germany and for children and adolescents. Until now there have been no representative and age-specific assessments of the prevalence of obesity among children and adolescents in Germany. Thus, the standardised height and weight measurements gathered in the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) have, for the first time, provided national, representative data about overweight and obesity in young people. The terms 'overweight' and 'obese' are defined based on percentiles of the body mass index (BMI) of the Kromeyer-Hauschild reference system. Of children and adolescents between the ages of 3 and 17, 15% exceed the 90th BMI percentile of the reference data and are thus overweight, 6.3% exceed the 97th BMI percentile and thus suffer from obesity by this definition. The proportion of overweight rises from 9% of 3-6-year-olds to 15% of 7-10-year-olds and 17% of 14-17-year-olds. The prevalence of obesity is 2.9%, 6.4% and 8.5% for the same age groups respectively. No clear differences between boys and girls or between East and West Germany are detected. Children are at a higher risk of being overweight or obese if they have a lower socioeconomic status, have a migration background, or have mothers who are also overweight.
