Body mass index, waist circumference and waist-to-hip-ratio in the prediction of obesity in Turkish teenagers

Publisher Copyright: © 2014, Croatian Anthropological Society. All rights reserved.The aim of this study was to identify the usefulness of body mass index (BMI), waist circumference (WC) and waist- -to-hip ratio (WHR) in screening for obesity in teenagers by using the receiver operating characteristic (ROC). To select the sample set in this cross-sectional study, a stratified random sampling approach was utilized.Weight, height, WC, hip circumference and body fat percentage (BFP) were measured in 1118 children of both genders (597 boys and 521 girls), aged from 10 to 15 years old. Percentiles of BMI and Centers for Disease Control and Prevention-United States (CDCUS)- growth chart for boys and girls aged from 10 to 15 years old were presented. ROC analyses were then used to evaluate the performances of three anthropometric indices; BMI, WC and WHR had strong positive correlations with BFP (r=0.49–0.77) in both girls and boys within indicated age group. The area under the curves (AUCs) were high in both girls and boys for BMI, 0.795 and 0.893, respectively, and WC, 0.767 and 0.853, respectively, and were a little lower, 0.747 and 0.783, respectively, for WHR. In conclusion, this study demonstrates that the prevalence of being overweight and obese among teenagers of both sexes in our data set does not differ from CDC-US-growth chart. In addition, BMI and WC are two important predictors for teenagers to become overweight and obese, while WHR is less useful for this purpose.publishersversionPeer reviewe

The Effects of Sport on the Body Measure from Students of Different Disciplines

Problems arising from excessive body weight may be overcome. Sport emerges to take a great part in this respect. This paper shows how human body is affected by sport.The individuals were selected from the students of two different disciplines. The body measure of students totaling to 200,, was then compared to those of the same number of students, who did not perform a regular physical activity. The values pertaining to the weight variable, implied a significant difference for both males and females. The BMI values obtained for the all students were in “no risk” group, while the average BMI values for the all female students, emerged to exhibit differences from those of the all male students.The results and the findings of this investigation implied that physical activities practiced regularly, have an influence on the body measure index of individuals

Anthropometric evaluation of mandibular characteristics in the medieval Kurdish population of Girê Kortikê: Sex-based variations and comparative analysis

Introduction: This research seeks to develop population-specific standards for skeletal sex determination, focusing on the medieval Kurdish population of Girê Kortikê and the mandible, a skull component presenting the highest degree of sexual dimorphism. This is the first study of its kind for this population. The research's primary objectives were to conduct anthropometric evaluations of several mandibular characteristics within this population, assess sex-based variations, determine relationships between various mandibular sizes, and contrast these findings with other existing studies. Materials and methods: A total of 121 mandibles (55 women, 66 men) were measured using 14 distinct anthropometric techniques, applying Pearson correlation coefficients, student's t-test, and principal component analysis (PCA) for comparison. Results: The study examined and discussed disparities between some chosen mandibular measurements and data from other populations. Statistically significant sex differences (p < 0.05) and correlations were identified in 12 of the anthropological measurements. The research found that the greater the height of the symphysis (GNI), the higher the foramen mentale height (FBB). Average measurements significantly deviated from the medieval Kurdish population when compared to populations in Santa Maria Xigui, Mexico (XIG), and Mexico City (MEX). Conclusion: No correlation was found between the height of the mandibular body (HML) and the mandible length (MLT). The study suggested distinct mandibular angle (MAN) sizes between sexes, indicating unique characteristics within the Girê Kortikê population, warranting further research for a more comprehensive evaluation. In conclusion, these findings emphasize the mandible's anatomical, historical, and cultural relevance in sex determination within the Girê Kortikê population

Compare of Structural and Functional Changes in Athletes, Hypertensive Patients and Healthy Sedentary Control Subjects

To asses cardiac structure and function in athletes, hypertensive patients and healthy sedentary control subjects by Doppler-echocardiographyOne hundred athletes, 45 hypertensive patients and 45 healthy sedentary control subjects volunteered to take part in the study, cardiac dimensions and function were determined by 2-D Doppler –echocardiography and were compared by One Way Anova test.There was not any significant relation in interventriculer septal thickness (IVST) between athletes and hypertensive patients (0,89±0.11-0,87±0.15). But there was a significant increase in athletes compared with sedentary subjects (0,89±0.11-0,77±0.14).there was a significant relation in deceleration time (DT) and in ratio of peak mitral velocity to mitral flow velocity at the time of atrial contraction (mEv/mAv) which is important for diastolic function compared three group (patients group has in favour of diastolic dysfunction, the other groups has normal limits of DT and mEv/mAv. Values of DT respectively athletes, patients, sedentary group (154±24, 240±54, 210±39). Values of mEv/mAv respectively athletes, patients, sedentary group (1.5±0.2, 1.1±0.2, 1.0±01).Although sedentary subject’s IVST was normal, athletes and hypertensive patients had increased IVST; but these increases did not impair diastolic function of heart also diastolic parameters in sedentary subjects was bigger than athletes
