<b><i>Introduction:</i></b> Body composition assessment is superior to the use of body mass index (BMI) to characterize the nutritional status in pediatric populations. For data interpretation, suitable reference data are needed; hence, we aimed to generate age-dependent and sex-specific body composition reference data in a larger population of children and adolescents in Germany. <b><i>Methods:</i></b> This is a cross-sectional study on a representative group of 15,392 5- to 17-year-old children and adolescents. Body composition was assessed by bioelectrical impedance analysis using a population-specific algorithm validated against air displacement plethysmography. Age- and sex-specific percentiles for BMI, fat mass index (FMI), fat-free mass index (FFMI), and a “load-capacity model” (characterized by the ratios of fat mass [FM]/ fatt-free mass [FFM] and FM/FFM<sup>2</sup>) were modeled using the LMS method. <b><i>Results:</i></b> BMI, FMI, FFMI, FM/FFM, and FM/FFM<sup>2</sup> curves showed similar shapes between boys and girls with steady increases in BMI, FMI, and FFMI, while FM/FFM<sup>2</sup>-centiles decreased during early childhood and adolescence. Sex differences were observed in FMI and FM/FFM percentiles with increases in FMI up to age 9 years followed by a steady decrease in FM/FFM during and after puberty with a fast-growing FFMI up to age 17 in boys. The prevalence of low FFM relative to FM reached more than 60% in overweight children and adolescents. <b><i>Conclusion:</i></b> These pediatric body composition reference data enable physicians and public health scientists to monitor body composition during growth and development and to interpret individual data. The data point out to an early risk of sarcopenia in overweight children and adolescents.

Background: Now a days unhealthy lifestyle primarily responsible for the dramatic increase obesity among children and adolescents. Objective: The purpose of the study is to see the effects of a multidisciplinary lifestyle intervention to reduce obese children and adolescents. The main outcome was cardiometabolic risk based on the waist-to-height ratio (WHTR) measurement. Secondary outcomes were (1) changes in body composition; (2) adherence to a Mediterranean diet; and (3) physical performance. Methods: The study involved 64 overweight/obese children or adolescents conducted at Dhaka Shishu Hospital from October 2017 to September 2018. The intervention was multidisciplinary including nutrition, exercise, and psychological aspects based on a family-based approach; it was delivered for six months for children and three months for adolescents. Before and after the intervention, several anthropometric measures height, body weight, body mass index (BMI), waist circumference, and body composition, cardiometabolic risk index waist-to-height ratio (WHTR), and dietary habits of the participants and their families were evaluated. In addition, a set of functional motor fitness tests was performed to evaluate physical performance measures. Results: After the intervention both children and adolescents showed a significant reduction in body weight, BMI, waist circumference, fat mass, and WHTR index and an improvement of fat-free mass, adherence to the Mediterranean diet, and physical fitness performance. Conclusion: A short term family-based multidisciplinary approach is effective in ameliorating the health status, dietary habits, and physical performance in children and adolescents.

(1) Background: Many professional Australian Football (AF) players do not meet recommended sports nutrition guidelines despite having access to nutrition advice. There are a range of factors that can influence players′ ability to meet their nutrition goals and awareness of the barriers players face is essential to ensure that dietary advice translates into practice. Therefore, this qualitative research study aimed to explore the factors influencing AF players’ dietary intakes and food choice. (2) Methods: Semi-structured interviews were conducted with twelve professional male AF players. (3) Results: Less experienced players restricted their carbohydrate intake to meet body composition goals, particularly during preseason and surrounding body composition assessment. During the competition season players had a greater focus on performance and placed more emphasis on carbohydrate intake in the lead up to matches. Players felt nutrition goals were easier to achieve when dietary choices were supported by their families and peers. One-on-one consultations provided by a sports dietitian were players′ preferred mode of nutrition intervention. Individualized nutrition advice is required for less experienced AF players who may be vulnerable to unsustainable dietary habits. Experienced AF players can support junior teammates by promoting positive team culture related to body composition, nutrition and performance.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction  Cardiovascular disease (CVD) is recognized as a major public health issue and remains the leading cause of mortality worldwide. There is a clear association between adiposity, blood lipid profile, and adherence to the Mediterranean diet (MD) with the risk of CVD. However, the assessment of body composition parameters, dietary patterns and nutritional intervention in CVD patients undergoing a cardiovascular rehabilitation (CR) program remains insufficient.  Purpose  to characterize body composition, lipid profile and MD adherence in patients with CVD who were attending an exercise-based CR program during COVID-19 era.  Methods  The study was developed between October 2020 and January 2021 in a phase III centre-based CR program. Body composition was assessed by dual energy x-ray absorptiometry Hologic Explorer-W. Adherence to the MD was assessed by the 14-item MD questionnaire. Fasting blood sample was taken for measurement of lipid profile.  Results  A sample of 41 patients (mean age 64.4 ± 7.9 years, 87.8% male) was evaluated. The most prevalent CVD were coronary artery disease (89.5%) and heart failure (21.1%). The main CVD risk factors at admission in the CR program were dyslipidaemia (71.1%), hypertension (68.4%), physical inactivity (26.3%) and diabetes mellitus (21.0%). In our sample the mean body mass index was 28 ± 3.8 kg/m2, being most patients overweight (75.6%), and having a substantially increased risk of metabolic complications (85.3%) accordingly to waist-hip ratio. Body composition assessment showed that 14.6% of the patients had a body fat mass index above 90th percentile. Although only 9.8% of the patients had reduced fat free mass, 17.1% showed appendicular lean mass below the reference value. In addition, less than one third of the patients (31.7%) revealed a high adherence to the MD pattern. A sub-analysis on blood lipids (n = 26) showed that most patients had levels of LDL cholesterol (76.9%) and non-HDL cholesterol (65.4%) above the therapeutic target and 15.4% had triglycerides higher than 150 mg/dl.  Conclusion  Body composition, lipid profile and dietary patterns, play a major role in CVD secondary prevention. Our findings showed that a substantial number of CVD patients, in COVID-19 era, did not have optimal body composition, were above lipid profile targets, and had a low/medium adherence to the MD. Thus, this study highlights the relevance of nutrition on cardiometabolic status and demonstrates the crucial role of nutritional intervention as an integrated part of a long-term phase III CR program. Moreover, further research about nutritional intervention in patients undergoing CR is warranted.

Fat Mass Ratio

Decreased muscle-to-fat mass ratio (MFR) is associated with pediatric nonalcoholic fatty liver disease (NAFLD) and may reduce muscular fitness. Regular exercise in sports clubs has not led to reductions in obesity in children and adolescents; they may have decreased MFR. Decreased MFR could cause reduced muscular fitness, which may put them at risk for NAFLD development. We investigated whether MFR is related to muscular fitness and serum alanine aminotransferase (ALT), to determine whether MFR could be used to screen for NAFLD in children and adolescent boys belonging to sports clubs. Altogether, 113 participants (aged 7–17 years) who underwent body composition, laboratory, and muscular fitness measurements during a medical checkup were divided into tertiles according to their MFR. Lower extremity muscular fitness values were significantly decreased in the lowest MFR tertile (p < 0.001); conversely, serum ALT levels were significantly increased (p < 0.01). Decreased MFR significantly increased the risk of elevated ALT, which requires screening for NAFLD, after adjusting for age, obesity, muscular fitness parameters, and metabolic risk factors (odds ratio = 8.53, 95% confidence interval = 1.60–45.6, p = 0.012). Physical fitness and body composition assessments, focusing on MFR, can be useful in improving performance and screening for NAFLD in children and adolescents exercising in sports clubs.

Abstract Background Current adult studies suggest that uric acid (UA) is associated with body fat, but the relationship in obese children is unclear. Thus, we aim to evaluate the association between uric acid and body composition of obese children. Methods A total of 79 obese children were included in this study, and 52 children (34 boys and 18 girls) underwent a 6-week weight loss camp, including 34 boys and 18 girls. Six-week weight-loss interventions were performed on all participants through aerobic exercise and appropriate dietary control. Laboratory tests and body composition were collected before and after the intervention. Results Before the intervention, correlation analysis demonstrated that uric acid was positively correlated with height, weight, body mass index (BMI), waist circumference, hip circumference, fat mass (FM), and free fat mass (FFM) with adjusting for age and gender (P < 0.05). After 6 weeks of intervention, the participants gained 3.12 ± 0.85 cm in height, body fat percentage decreased by 7.23 ± 1.97%, and lost 10.30 ± 2.83 kg in weight. Univariate and multivariate analysis indicated that uric acid at baseline was associated with FM reduction during weight loss (P < 0.05). Conclusions This study is the first report that uric acid is associated with BMI and FM, and may play an important role in the reduction of FM during weight loss in obese children and adolescents. The interaction between UA and adiposity factors and its underlying mechanisms need to be further explored. Trial registration This study was registered in Clinical Trials.gov (NCT03490448) and approved by the Ethics Committee of Xinhua Hospital, Shanghai Jiao Tong University School of Medicine.
