PURPOSE: To evaluate the accuracy of the body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR) in detecting excess body fat among schoolchildren in Florianópolis, Santa Catarina. METHODS: Cross-sectional study with 2,772 schoolchildren aged seven to ten years. Receiver Operating Characteristic (ROC) curves were used to compare the diagnostic accuracy of the BMI, the WC and the WHtR in identifying children with excess body fat (defined as values that were equal to or higher than the 90th percentile of the standardized residuals obtained from the sum of the four skinfolds thickness). Likelihood ratio estimates were used to select, for each anthropometric index, the cut-off points that presented the highest association with excess body fat. RESULTS: The BMI, WC and WHtR performed well in detecting excess body fat, indicated by areas under the ROC curve (AUC) close to 1.0, with slightly higher AUC for the BMI in comparison to the WC and the WHtR concerning both sexes. Highly sensitive and specific cut-off points were derived for the three anthropometric indices. Sensitivity ranged from 85.7 to 92.9% for the BMI, from 78.6 to 89.7% for the WC, and from 78.6 to 89.2% for the WHtR. Specificity ranged from 83.2 to 91.4%, from 75.0 to 90.7%, and from 77.4 to 88.3% for the BMI, the WC and the WHtR, respectively. CONCLUSION: BMI, WC and WHtR can be used as diagnostic tests to identify excess body fat in children from seven to ten years of age.

AbstractPhysical fitness is the ability of a person body to do a day work without feeling significant fatigue, that the body has a reserve of energy to overcome the excessive workload. The purpose of this study was to determine the relationship between hydration knowledge, hydration status, body composition, hemoglobin level with physical fitness in gymnastics athletes. This study was design a cross sectional study at GOR Raden Inten East Jakarta. Independent variables were hydration knowledge, hydration status, body composition (percent of body fat) and hemoglobin level, while the dependent variable was physical fitness. The statistical test used in this study was the spearman correlation test, because the dependent variable in this study was abnormally distributed. The results of this study were that there was no significant relationship between hydration knowledge and physical fitness (r = 0.181; p > 0.05), there was no significant relationship between hydration status and physical fitness (r = -0,440; p = 0,052), there was no relationship significant between body composition (percent of body fat) and physical fitness (r = 0,351; p > 0.05), and there was a significant relationship between hemoglobin level and physical fitness (r = 0,600; p < 0.05). The conclusion in this study, there was a significant relationship between hemoglobin level and physical fitness.Kebugaran jasmani merupakan kemampuan tubuh seseorang untuk melakukan suatu pekerjaan sehari-hari tanpa merasakan kelelahan yang cukup berarti, sehingga tubuh itu sendiri memiliki cadangan energi untuk mengatasi beban kerja yang berlebih.

AbstractObjective:To propose a new anthropometric index that can be employed to better predict percent body fat (PBF) among young adults and to compare with current anthropometric indices.Design:Cross-sectional.Setting:All measurements were taken in a controlled laboratory setting in Seoul (South Korea), between 1 December 2015 and 30 June 2016.Participants:Eighty-seven young adults (18–35 years) who underwent dual-energy x-ray absorptiometry (DXA) were used for analysis. Multiple regression analyses were conducted to develop a body fat index (BFI) using simple demographic and anthropometric information. Correlations of DXA measured PBF (DXA_PBF) with previously developed anthropometric indices and the BFI were analysed. Receiver operating characteristic curve analyses were conducted to compare the ability of anthropometric indices to identify obese individuals.Results:BFI showed a strong correlation with DXA_PBF (r = 0·84), which was higher than the correlations of DXA_PBF with the traditional (waist circumference, r = 0·49; waist to height ratio, r = 0·68; BMI, r = 0·36) and alternate anthropometric indices (a body shape index, r = 0·47; body roundness index, r = 0·68; body adiposity index, r = 0·70). Moreover, the BFI showed higher accuracy at identifying obese individuals (area under the curve (AUC) = 0·91), compared with the other anthropometric indices (AUC = 0·71–0·86).Conclusions:The BFI can accurately predict DXA_PBF in young adults, using simple demographic and anthropometric information that are commonly available in research and clinical settings. However, larger representative studies are required to build on our findings.

BACKGROUND: Maximum oxygen consumption (VO2 max) is an important measure of cardiovascular capacity to deliver oxygen to the working muscle at maximal exercise. Anthropometrics is one of the factors that contribute to the maximum oxygen consumption. OBJECTIVE: This study aimed to predict the maximum oxygen consumption based on anthropometrics in the emergency medicine students. METHODS: This cross-sectional study was conducted on the emergency medicine students (n = 56) at Qazvin University of Medical Sciences. Before the data collection, participants completed the consent form and Physical Activity Readiness Questionnaire (PAR-Q). Then, the maximum oxygen consumption and anthropometrics (dimensions and compositions) were measured using Gerkin treadmill test and using tape, anthropometer device and digital caliper respectively. Data were analyzed using Pearson correlation, one-way analysis of variance and multivariate linear regression. RESULTS: The mean of maximum oxygen consumption was 4.11 lit/min in the emergency medicine students. There was a significant relationship between maximum oxygen consumption and anthropometrics (body dimensions and compositions including body fat, waist to hip circumference, and BMI) (p <  0.05). Also, the leg length, the body fat, and the BMI predicted 72% of oxygen consumption. The leg length and BMI had an important role in predicting the maximum oxygen consumption. CONCLUSIONS: The body dimensions and compositions should be taken into consideration to select students and match their capabilities with required energy for the job.

BACKGROUND With the availability of more sophisticated methods, the utility of body mass index (BMI) as a measure of obesity and body fat estimation is being questioned. The current study aims to compare the estimation of body fat derived from BMI to that of directly measured bio impedance analysis (BIA). METHODS This is a cross sectional study conducted among IT employees of Bangalore City. Body fat % estimated from BMI using formula (adult BF = (1.20 x BMI) + (0.23 x age) - (10.8 x sex) - 5.4 where value for male = 1 & female = 0) and bioimpedance analysis (BIA) was compared using Bland-Altman analysis. RESULTS A total of 6901 participants were included and out of 6901 participants, 67.63 % were women. The mean age was 29.6 ± 6.68 years. The mean of the difference in body fat % calculated from BMI and estimated by BIA was 3.29, (- 9.99 to + 16.58 %). The mean difference was 3.43, (- 9.58 to + 16.45 %) and 2.89, (- 10.90 to + 16.68 %) among men and women respectively. CONCLUSIONS The results showed that the body fat estimated by BMI varies significantly from body fat estimated from BIA.

Objective. To identify the degree of association between anthropometric indices and components of metabolic syndrome (MS) and to determine optimal cut-off points of these indices for predicting MS in obese adolescents.Methods. A cross-sectional study with a sample of (n=110) Mexican obese adolescents grouped by sex and the presence/absence of MS. BMI percentile, waist circumference (WC), and waist-to-height ratio (WHtR) were tested. ROC curves of the anthropometric indices were created to identify whether an index was a significant predictor of MS.Results. BMI percentile, WC, and WHtR were significantly correlated with systolic and diastolic blood pressure. As predictors of MS overall patients, the BMI percentile generated an area under curve (AUC) of 0.651 (P=0.008), cut-off point above the 99th percentile. WC generated an AUC of 0.704 (P<0.001), cut-off point of ≥90 cm. WHtR demonstrated an AUC of 0.652 (P=0.008), cut-off point of 0.60. WHtR ≥0.62 and WHtR ≥0.61 generate AUC of 0.737 (P=0.006) and AUC of 0.717 (P=0.014) for predicting hypertension and insulin resistance, respectively, in females.Conclusion. WHtR is a better tool than WC and BMI for identifying cardiometabolic risk. The overall criterion (WHtR ≥ 0.6) could be appropriate for predicting MS in obese Mexican adolescents.

De acuerdo a investigaciones recientes, el consumo de lácteos, además de presentar un alto valor nutritivo, se asocia a un menor peso corporal, atribuyéndole importantes beneficios para la salud. El objetivo del estudio es asociar el consumo de lácteos con la composición corporal, en hombres físicamente activos. Estudio transversal analítico, se evaluaron a 375 hombres, se aplicó encuesta de hábitos alimentarios y antropometría. De los voluntarios evaluados, la edad promedio fue de 23,8 ± 6,9 todos con escolaridad secundaria completa. Con respecto al consumo de lácteos el 35,5 % consumía al menos de 1 vez al día, 28 % 1 porción al día, 9,3% 2 porciones al día y 2,9 % 3 porciones/día. Los que consumen ≥2 porción de lácteos al día presentaban menor IMC, peso y grasa corporal, que aquellos que consumen < de 2 porciones de lácteos. Se presentan correlaciones negativas entre una mayor frecuencia de consumo de lácteos con grasa corporal, % grasa corporal y relación cintura cadera. Al asociar el consumo de ≥ 2 porciones se observó una asociación negativa con % grasa corporal. Finalmente, los sujetos que consumen ≥2 porciones/día de lácteos presentan significativamente menor IMC, peso y % grasa corporal, al realizar las asociaciones con el consumo de ≥ 2 porciones de lácteos solo se mantiene el % de grasa corporal. According to recent research, the consumption of dairy, in addition to presenting a high nutritional value, is associated with lower body weight, attributing important health benefits. The objety of the study is to associate dairy consumption with body composition in physically active men. Analytical cross-sectional study, 375 men were evaluated, in which a survey of eating habits and anthropometry was applied. Of the volunteers evaluated, the mean age was 23.8 ± 6.9 years and all had completed secondary education. Regarding dairy consumption, 35.5 % consumed at least 1 time a day, 28 % 1 portion a day, 9.3 % 2 portions a day and 2.9 % 3 portions / day. Those who consumed ≥2 servings of dairy products per day had lower BMI, weight and body fat than those who consumed <2 servings of dairy. There are negative correlations between a higher frequency of dairy consumption with body fat (k), body fat % and waist-to-hip ratio. When associating the consumption of ≥ 2 servings, a negative association with body fat% was observed. Finally, the subjects who consume ≥2 servings / day of dairy products have significantly lower BMI, weight and body fat%, when making the associations with the consumption of ≥ 2 servings of dairy only the % body fat is maintained.

The university represents a critical space for students in terms of prevalence of malnutrition. The objective of this study was to determine the body mass index (BMI), body fat percentage (% BF), waist circumference (WC), and anemia in university students. A cross-sectional study was carried out in 2,285 university students from Lima, Peru. The sample was selected by nonprobability convenience sampling. Anthropometric data and hemoglobin levels were measured. The Chi-square test was used. The analysis of the associated factors was done using binary logistic regression. A significance level of 5% was considered. There were no significant differences between men and women in BMI ( p > 0.05 ). The men presented significantly high and very high levels of % BF ( p < 0.001 ). The proportion of women who presented anemia and high and very high WC was significantly higher compared to men ( p < 0.001 ). Being older than 27 years (ORB = 2.07; 95% CI = 1.19–3.6), being male (ORB = 2.68; 95% CI = 2.02–3.55), studying at the engineering faculty (ORB = 1.39; 95% CI = 1.09–1.79), having excess body fat (ORB = 8.17; 95% CI = 6.13–10.87), and having an elevated WC (ORB = 35.51; 95% CI = 25.06–50.33) significantly predicted overweight/obesity. The findings of this study suggest that college students, especially males and those who are not enrolled in health sciences colleges, should be a priority in healthy lifestyle interventions, particularly nutritional education programs, to reduce the prevalence of overweight and obesity.

OBJECTIVE: To describe lung function findings in overweight children and adolescents without respiratory disease. METHODS: This was a cross-sectional study involving male and female overweight children and adolescents in the 8-18 year age bracket, without respiratory disease. All of the participants underwent anthropometric assessment, chest X-ray, pulse oximetry, spirometry, and lung volume measurements. Individuals with respiratory disease were excluded, as were those who were smokers, those with abnormal chest X-rays, and those with an SpO2 = 92%. Waist circumference was measured in centimeters. The body mass index-for-age Z score for boys and girls was used in order to classify the individuals as overweight, obese, or severely obese. Lung function variables were expressed in percentage of the predicted value and were correlated with the anthropometric indices. RESULTS: We included 59 individuals (30 males and 29 females). The mean age was 11.7 ± 2.7 years. Lung function was normal in 21 individuals (35.6%). Of the 38 remaining individuals, 19 (32.2%), 15 (25.4%), and 4 (6.7%) presented with obstructive, restrictive, and mixed ventilatory disorder, respectively. The bronchodilator response was positive in 15 individuals (25.4%), and TLC measurements revealed that all of the individuals with reduced VC had restrictive ventilatory disorder. There were significant negative correlations between the anthropometric indices and the Tiffeneau index in the individuals with mixed ventilatory disorder. CONCLUSIONS: Lung function was abnormal in approximately 65% of the individuals evaluated here, all of whom were overweight. Obstructive ventilatory disorder and positive bronchodilator response predominated.
