The aim of the study was to analyze sleep duration and behaviors in relation to psychological parameters in children and adolescents with obesity seeking inpatient weight-loss treatment in comparison to normal-weight children, and whether or not these variables would improve during the time course of treatment. Sixty children or adolescents with overweight and obesity (OBE) and 27 normal-weight (NW) peers (age: 9–17) were assessed for subjective sleep measures through self-reported and parent-reported questionnaires, as well as body weight, body composition, and psychological questionnaires. The OBE participants were assessed upon admission and before discharge of an inpatient multidisciplinary weight-loss program. NW participants' data were collected for cross-sectional comparison. In comparison to NW, children and adolescents with OBE had a shorter self-reported sleep duration and had poorer sleep behaviors and more sleep-disordered breathing as reported by their parents. No change in sleep measures occurred during the inpatient treatment. Psychological factors including higher anxiety, depression, and destructive-anger-related emotion regulation were moderate predictors for unfavorable sleep outcomes, independent of weight status. Children with obesity had less favorable sleep patterns, and psychological factors influenced sleep in children, independent of weight. More research is needed on the relationship and direction of influence between sleep, psychological factors, and obesity, and whether they can be integrated in the prevention and management of childhood obesity and possibly also other pediatric diseases.

Skeletal Robusticity

Background Over the last 20 years, a decreasing trend in external skeletal robusticity and an increasing trend in overweight and obesity was observed worldwide in adults and children as modern lifestyles in nutritional and activity behavior have changed. However, body mass index (BMI) as a measure for overweight is not an ideal predictor of % body fat (%BF) either in children and adolescents or in adults. On the contrary, it disguises a phenomenon called “hidden obesity”. Objectives We aim to approximate %BF by combining skeletal robusticity and BMI and develop an estimation-based tool to identify normal weight obese children and adolescents. Sample and Methods We analyzed cross-sectional data on height, weight, elbow breadth, and skinfold thickness (triceps and subscapular) of German children aged 6 to 18 years (N=15,034). We used modified Hattori charts and multiple linear regression to develop a tool, the “%BF estimator”, to estimate %BF by using BMI and skeletal robusticity measured as Frame Index. Results Independent of sex and age an increase in BMI is associated with an increase in %BF, an increase in Frame Index is associated with a decrease in %BF. The developed tool “%BF estimator” allows the estimation of %BF per sex and age group after calculation of BMI and Frame Index. Conclusion The “%BF estimator” is an easily applicable tool for the estimation of %BF in respect of body composition for clinical practice, screening, and public health research. It is non-invasive and has high accuracy. Further, it allows the identification of normal weight obese children and adolescents.

AbstractObjectiveA variety of methods are available for defining undernutrition (thinness/underweight/under-fat) and overnutrition (overweight/obesity/over-fat). The extent to which these definitions agree is unclear. The present cross-sectional study aimed to assess agreement between widely used methods of assessing nutritional status in children and adolescents, and to examine the benefit of body composition estimates.DesignThe main objective of the cross-sectional study was to assess underweight, overweight and obesity using four methods: (i) BMI-for-age using WHO (2007) reference data; (ii) BMI-for-age using Cole et al. and International Obesity Taskforce cut-offs; (iii) weight-for-age using the National Centre for Health Statistics/WHO growth reference 1977; and (iv) body fat percentage estimated by bio-impedance (body fat reference curves for children of McCarthy et al., 2006). Comparisons were made between methods using weighted kappa analyses.SettingRural South Africa.SubjectsIndividuals (n 1519) in three age groups (school grade 1, mean age 7 years; grade 5, mean age 11 years; grade 9, mean age 15 years).ResultsIn boys, prevalence of unhealthy weight status (both under- and overnutrition) was much higher at all ages with body fatness measures than with simple anthropometric proxies for body fatness; agreement between fatness and weight-based measures was fair or slight using Landis and Koch categories. In girls, prevalence of unhealthy weight status was also higher with body fatness than with proxies, although agreement between measures ranged from fair to substantial.ConclusionsMethods for defining under- and overnutrition should not be considered equivalent. Weight-based measures provide highly conservative estimates of unhealthy weight status, possibly more conservative in boys. Simple body composition measures may be more informative than anthropometry for nutritional surveillance of children and adolescents.

Introduction/Aim: 41 million children under the age of 5 and 340 million children and adolescents aged 5 to 19 are overweight or obese. Obesity in children and adolescents is the most important predictor of high blood pressure. The aim of the study was to examine the incidence of overweight and obesity in primary school children aged 6 to 15 years, as well as to examine the incidence of prehypertension and hypertension in children who were overweight and obese. Method: The study included 85 of 86 children from the Primary School "Krupa na Uni". Data were collected with the help of a questionnaire, while body weight and blood pressure were measured. The chi-square test and t-test were used for the statistical analysis of data Results: The cross-sectional study included 85 children, 45 (52.9%) boys and 40 (47.1%) girls with an average age of 10.87 ± 2.70 years. Normal weight was found in 54 (63.5%) subjects, underweight in 12 (14.1%), overweight in 5 (5.9%), and obesity in 14 (16.5%). 76 (89.4%) subjects had normal blood pressure values, 5 (5.9%) prehypertensive state, and 4 (4.7%) arterial hypertension. There was no significant difference between younger and older children regarding their nutritional status (p=0.477) and blood pressure levels (p=0.453). Children who were overweight and obese had prehypertension and hypertension significantly more often (p˂0.001). Conclusion: Every fifth child was overweight or obese, while prehypertension or hypertension were found in every tenth child. The timely change of diet and physical activity could contribute to the regulation of body weight and the regulation of blood pressure, as well.

Abstract Background In order to study the high blood pressure of children and adolescents and its influencing factors, it provides evidence-based evidence for the high blood pressure prevention of primary and secondary school students. Methods This study is a cross-sectional survey, which uses stratified cluster sampling method to select students from 7 schools to participate in questionnaire survey and physical examination. The correlation between single factor and high blood pressure was analyzed by chi-square test, and multivariate logistic regression analysis was used for multivariate analysis. Results A total of 1,814 subjects, including 512 primary school students (28.22%), 499 junior high school students (27.51%), 563 senior high school (31.04%), and 240 vocational high school (13.23%). There were 1000 males (55.13%) and 814 females (44.70%). The average age was 13.64±2.65 years. The detection rate of high blood pressure was 9.76%. Multivariate logistic regression analysis showed that the age groups were 10~ and 14~ (OR=20.870, 95%CI=2.372-183.666; OR=10.049, 95%CI=1.306-77.353) , sleep duration < 7h (OR=4.136, 95%CI=4.136), and physical education class times ≤2 times per week (OR=5.073, 95%CI=2.497-10.306), which were risk factors for high blood pressure in children and adolescents. Normal weight and overweight group were protective factors compared to the obesity group (OR=0.094, 95%CI=0.061-0.146; OR=0.225, 95%CI=0.134-0.378). Conclusion The age groups of 14~ and 16~ years old, physical education classes ≤ 2 times per week, and sleep duration <7h were risk factors for primary and secondary school students, and BMI of Normal weight and overweight group were protective factors compared to the obesity group students.

AbstractObjectiveThe purpose was to examine the associations among body weight status, blood pressure and daily Na intake among grade 7 students from south-western Ontario, Canada.DesignCross-sectional. Data were collected using the Food Behaviour Questionnaire, including a 24 h diet recall. Measured height and weight were used to determine BMI. Blood pressure was taken manually using mercury sphygmomanometers.SettingTwenty-six schools in south-western Ontario, Canada.SubjectsGrade 7 students (n1068).ResultsBody weight status indicated 1 % were underweight, 56 % normal weight, 23 % overweight and 20 % were obese. Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 108·3 (sd10·3) mmHg and 66·0 (sd7·5) mmHg, respectively, and mean Na intake was 2799 (sd1539) mg/d. Bivariate analyses suggested that SBP (P< 0·001) and DBP (P< 0·001) were significantly different by body weight status, yet no associations were observed for Na. Adjusted for gender, ethnicity and under-reporting, participants were more likely to be overweight/obese if they had higher SBP (v.lower: OR = 1·06, 95 % CI 1·05, 1·08,P< 0·001), higher DBP (v.lower: OR = 1·02, 95 % CI 1·00, 1·04,P= 0·043) and higher intakes of Na (3rdv.1st quartile: OR = 1·72, 95 % CI 1·14, 2·59,P= 0·009; 4thv.1st quartile: OR = 2·88, 95 % CI, 1·76, 4·73,P< 0·001).ConclusionsHigh intakes of Na, coupled with high SBP and DBP, were associated with overweight and obesity status among the grade 7 sample from south-western Ontario, Canada.

AbstractObjectiveNutritional status during childhood plays an important role in the human life cycle. The present study examined the prevalence trends in different grades of nutritional status (thinness, normal weight, overweight and obesity) among children and adolescents in Shandong, China.DesignData for the study were obtained from six cross-sectional surveys of schoolchildren carried out in 1985, 1995, 2000, 2005, 2010 and 2014. Height and weight of all children were measured; BMI was calculated from their height and weight. International BMI cut-offs were used to define thinness, overweight and obesity.SettingShandong Province, China.SubjectsA total of 56 045 students aged 7–18 years were included in the current analysis.ResultsIn the past 29 years, the prevalence of thinness decreased from 18·22 % and 23·45 % in 1985 to 7·18 % and 9·49 % in 2014 for boys and girls, respectively. Conversely, the prevalence of combined overweight and obesity increased from 1·79 % and 1·66 % in 1985 to 31·12 % and 20·11 % in 2014 for boys and girls, respectively.ConclusionsThe nutritional profile of Shandong children and adolescents had an obvious change over the past 29 years. Special attention should be paid to controlling the rapid rise of childhood overweight and obesity.

Introduction: Childhood obesity is now rising as a significant health problem. In India, some studies showed a rising trend in the prevalence of overweight and obesity in children. This shocking rise in childhood obesity often accounts for increased intake of high calorie foods and decreased physical activity. In addition, non communicable diseases like diabetes mellitus, cardiovascular diseases and cancer are more common in obesity. Aim: To assess the relationship between cardiopulmonary fitness and Body Mass Index (BMI) in school going adolescents between 12 to 16 years. Materials and Methods: This study was a cross-sectional observational study conducted from March 2018 to March 2019. The study included 60 healthy students (between 12 to 16 years) full sample size divided into two groups and four subgroups. After the general physical examination and history taking, participants’ selection made in line with pre-defined inclusion and exclusion criteria. Anthropometric and body composition parameters were recorded. Using the modified Harvard’s Step test, cardiopulmonary fitness parameters like Physical Fitness Index (PFI) and Maximal oxygen consumption (VO2max) of each subject were calculated by applying the concerned formulae. All statistical analysis has been done by using Statistical Package for the Social Sciences (SPSS) software version 16.0. Results: Total 60 apparently healthy students included 30 males and 30 females. Mean age was 14.93±0.96 years in Group I (normal weight boys, n=15) and 14.47±1.41 years in Group II (overweight/obese boys, n=15). Also mean age was 14.93±0.59 years in Group III (normal weight girls, n=15) and 15.27±0.59 years in Group IV (overweight/obese girls, n=15). Pearson correlation showed a significant negative correlation between BMI and PFI (r=-0.504, p-value <0.001) also between BMI and VO2max (r=-0.459, p-value <0.001). Conclusion: Appropriate measures should be taken to enhance cardiopulmonary fitness among school children who are the wealth of the country at the school and community levels.

La obesidad infantil ha incrementado su prevalencia en España, y aunque se considera un problema multifactorial, es atribuible principalmente al aumento de la ingesta y la disminución de la actividad física por un ocio sedentario mayor. El objetivo de este estudio fue conocer la prevalencia de sobrepeso y obesidad infantil en la Zona Básica de Salud (ZBS) de Menasalbas (Toledo, España), y la influencia de los hábitos alimentarios, de actividad física y deporte, y de ocio sedentario. Se realizó un estudio transversal en la población escolarizada de 3 a 12 años de la ZBS de Menasalbas, tomando medidas de peso y talla a 725 menores, calculando su IMC y clasificando su estado ponderal según las tablas de Cole. También se recogieron datos referentes a sus hábitos alimentarios y cuestionario Kidmed de adherencia a la dieta mediterránea, y hábitos de actividad física y ocio sedentario, para estudiar su relación con el estado ponderal de los menores. La prevalencia de sobrecarga ponderal (suma de prevalencias de sobrepeso y obesidad) fue del 24,9%, con un 18,8% de sobrepeso y un 6,1% de obesidad, sin diferencias por edad y sexo. No se observaron diferencias respecto a los hábitos alimentarios, pero si una menor actividad física y un mayor ocio sedentario en aquellos con sobrecarga ponderal. La prevalencia de sobrepeso y obesidad en nuestra población es elevada, aunque menor a las de otros trabajos. La alimentación, la actividad física y el ocio sedentario influenciaron el sobrepeso y la obesidad infantil en este estudio. Childhood obesity has increased its prevalence in Spain, and although it´s considered a multifactorial problem, it is mainly attributable to increased intake and decreased physical activity due to increased sedentary leisure. The objective of this study was to know the prevalence of overweight and childhood obesity in the Basic Health Zone (ZBS) of Menasalbas (Toledo, Spain), and the influence of eating habits, physical activity and sport, and sedentary entertainment. A cross-sectional study was conducted in the school children of 3 to 12 years of age in the ZBS of Menasalbas, taking weight and height measurements for 725 minors, calculating their BMI and classifying their weight status according to Cole´s tables. Data regarding their eating habits and Kidmed questionnaire of adherence to the mediterranean diet, physical activity habits and sedentary leisure habits were also collected, to study its relationship with the weigh status of minors. The prevalence of weight overload (understood as the sum of the prevalence of overweight and obesity) was 24.9% , with 18.8% overweight and 6.1% of obesity, with no differences by age and sex. No differences were observed regarding eating habits, but less physical activity and a more sedentary leisure in those with weight overload was observed. The prevalence of overweight and obesity in our population is high, although lower than reported in other works. Diet, physical activity and sedentary leisure are confirmed as fundamental aspects in childhood overweight and obesity.

Obesity is caused by fat accumulation. BMI Z-score is used to classify the different degrees of weight status in children and adolescents. However, this parameter does not always express the true percentage of body fat. Our objective was to determine the degree of agreement between the fat mass percentage measured by DXA and the stratification of weight according to BMI Z-score in the pediatric age group. We designed a descriptive cross-sectional study. The patients were classified as underweight/normal weight with Z-scores between −2 and +0.99, overweight from 1 to 1.99, obese from 2 to 2.99, and very obese ≥3. We included 551 patients (47% girls), with a mean age of 11.5 ± 2.8 years (3.7–18 years). Higher BMI Z-scores were associated with a higher percentage of total fat (p < 0.001). However, there were important overlaps between both parameters, such that the BMI Z-score classified patients with the same percentage of total fat mass as having a different nutritional status classification. In conclusion, the stratification of weight status according to BMI Z-score revealed that 46.7% of patients had a fat percentage that did not correspond to their classification. For a more accurate weight assessment in clinical practice, we recommend combining anthropometric indices with diagnostic tools that better correlate with DXA, such as electrical bioimpedance.

AbstractObjectivePrevious studies in China showed large sex differences in childhood overweight and obesity (OW/OB) rates. However, limited research has examined the cause of these sex differences. The present study aimed to examine individual and parental/familial factors associated with sex differences in childhood OW/OB rates in China.DesignVariables associated with child weight status, beliefs and behaviours, and obesity-related parenting practices were selected to examine their sex differences and association with a sex difference in child OW/OB outcomes using logistic regression analysis.SettingCross-sectional data analysis using the 2011 China Health and Nutrition Survey.SubjectsChildren aged 6–17 years (n 1544) and their parents.ResultsOverall child OW/OB prevalence was 16·8 %. Adolescent boys (AB; 12–17 years) were about twice as likely to be overweight/obese as adolescent girls (AG; 15·5 v. 8·4 %, P<0·05). AB more likely had energy intake exceeding recommendations, self-perceived underweight, underestimated their body weight and were satisfied with their physical activity level than AG. AG more likely practised weight-loss management through diet and self-perceived overweight than AB. Mothers more likely identified AG’s weight accurately but underestimated AB’s weight. Stronger associations with risk of childhood OW/OB were found in boys than girls in dieting to lose weight (OR=6·7 in boys v. 2·6 in girls) and combined maternal and child perception of the child’s overweight (OR=35·4 in boys v. 14·2 in girls).ConclusionsLarge sex differences in childhood obesity may be related to the sex disparities in weight-related beliefs and behaviours among children and their parents in China.
