“…It is also noteworthy the strong correlation found between VAI, BF% and FFBI, in the MUH group, and the highest means of these variables, observed in adolescents with inadequate phenotype. These data corroborate with results demonstrated by Oliveira et al [47] who, when analyzing factors related to cardiometabolic risk in adolescents, identified that the overweight group had a higher FFBI when compared to subjects with adequate BMI and WC. This characteristic can be justified by behavioral changes, such as decreased level of physical activity and poor eating habits, in addition to changes in glucose and lipid metabolism, which are common during adolescence [48,42].…”

Background The metabolically healthy (MH) and metabolically unhealthy (MUH) phenotypes have been discussed in the literature but the factors related to the development of these phenotypes, in adolescents with adwuate and high body mass index (BMI), are not yet fully understood. Objective To evaluate the relationship between age during the menarche, serum leptin concentrations, body composition and MH and MUH phenotypes, in adolescents with adequate and high BMI. Methods Observational and cross-sectional study made up of female adolescents attended at Centro de Referência do Adolescente, in Macaé, Rio de Janeiro. The stage of sexual maturation and the age at menarche were analyzed based on the self-declaration of the participants. The menarche was considered early (EM) when the first menstruation occurred up to 11 years of age; normal (NM) between 12 and 14 years old; and late after 15 years of age. Body mass and height were measured to calculate BMI, and the following body variables were analyzed: waist circumference (WC), waist/height ratio (WHR), body fat (BF%), fat body mass index (FBMI) and fat-free mass index (FFMI), visceral adiposity index (VAI). In addition, cardiometabolic components and serum leptin concentrations were measured.Results 82% (n=114) of the adolescents were classified as MH and 18% (n=25) as MU. The mean age at menarche was 11.79 ± 1.39 years. 60% (n=15) of EM and 84% (n=21) of inadequacy of serum leptin were identified in the MUH group. Among eutrophic women, there was 85.7% (n=6) of inadequate WC among MUH adolescents and 2.5% (n=2) among MH ones ( p <0.01), while among adolescents with high BMI, 88.9% (n=16) and 28.6 (n=10) of the MUH and MH groups, respectively, showed inadequacy of this variable ( p <0.01). Among MUH adolescents, there was a strong correlation between the age at menarche and BF% (r= - 0.63 p <0.01); VAI and TG (r=0.87 p <0.01), BF% (r=0.63 p <0.01) and FFM (r=0.61 p <0.01). Conclusion Age at menarche, serum leptin and WC are related to the MUH phenotype in adolescents and should be investigated, during clinical practice, to help prevent cardiometabolic diseases in adulthood.

“…However, these authors considered body fat indexes above 25% for boys and 30% for girls 7 as a parameter for obesity 7 , whereas in this study, it was considered Above the Ideal at 20% and 25%, respectively. On the other hand, the results found in the present study are similar to those of a study carried out in southeastern Brazil that evaluated 403 adolescents between 10 and 14 years of age that detected overweight in 30.1% of those evaluated in both sex 19 .…”

Introduction:Motor coordination is a result of interactions between many body systems, producing accurate and balanced kinetic actions. The evaluation of motor performance levels in children and teenagers may conserve and improve health and life qualities. Body composition may interfere considerably in motor coordination, particularly in overweight and obese conditions. Objective: To analyse the relationships between motor performance and body composition in children. Methods:Motor coordination was evaluated through the Körperkoordinations test für Kinder (KTK test), considering the motor quotient (MQ) and body composition using the body fat percentage (BF%) and body mass index (BMI).Results: BMI (38% and 36%) and BF% (28% and 22%), from boys and girls respectively, demonstrated that body composition is above the recommended. Girls presented MQ values lower than those observed in boys (p < 0.001). The groups with BFPs below the recommended value showed higher values of MQ than the normal group (p<0.05) and than children above the recommended ideal (p < 0.05). A reverse correlation was observed between MQ with BF% (r = -0.432) or BMI (r = -0.254). Conclusion:There are relationships between body composition and motor coordination in teenagers between 11 and 14 years old, related or not to gender and age. Why was this study done?This study was part of the master's dissertation of Prof. Giliard Mores in the Graduate Program in Physical Education at UFMT (Federal University of Mato Grosso). The theme was the result of the author's observation, as an active teacher of the State Basic Education Network, of disinterest in the practice of physical activities, increase of obesity and decrease in the motor capacity of students in the last decade. What did the researchers do and find?Using KTK (Körperkoordinationstest für Kinder), the evaluation of body mass index and body fat percentage, in 105 students, the aim was to investigate the relationship between motor performance and body composition in schoolchildren. Through this study, according to the tests applied, there was a high incidence of students with performance deficits to perform motor tasks, elevated rates of overweight and obesity, and a strong relationship between the increase in adiposity levels and a decrease in motor performance in the study population. What do these findings mean?They mean the need for greater care with the factors that trigger obesity, especially sedentary lifestyle, in children and adolescents, since they are related to the level of motor performance, which may reflect in the practice of physical activity and the health of these individuals at the moment current and adult life.

“…However, researchers mostly agree on the high level of precision that the FMI must diagnose adipose hypertrophy with. High FMI has been correlated in teens with hypertriglyceridemia, high risk of cardiac disease, and elevated waist circumference [17].…”

Predictive formulas to estimate body composition in children have been explored for some time, to this date, the most accurate obesity diagnostic tool is to determine fat mass. The aim of this study is to establish cutoff points that allow for a precise interpretation of nutritional status using the Fat Mass Index (FMI) in a Mexican pediatric population. A literature review using PubMed and Cochrane databases was made, searching for research articles on childhood obesity that compared BMI, FM percentage, and FMI, as well as those proposing diagnostic cutoff points. Mathematic formulas and linear regressions were then used to make a proposal on accurate cutoff points for this population. Our findings show that FM percentage is less precise than BMI and FMI in diagnosing obesity, and FMI seems to be a more complete tool for assessment as it differentiates fat and muscle mass of the total body weight. Both BMI and FMI should be considered when clinical evaluations regarding weight, with BMI complementing FMI by establishing fat-free mass. Our proposed cutoff points need to be validated in this population.
