Abstract:
Background: Childhood obesity is a precursor for later disease risk and it is important to obtain a better understanding of the body composition and body mass index (BMI) in children. Objective: To determine the body composition and its relation with BMI of adolescents. Materials and Methods: A cross sectional study of 3356 school children in age group 12 to 19 years residing in Imphal-West District, Manipur was conducted during May 2005 to May 2008. BMI and Body composition were determined using the TANITA Body Composition Analyzer (TBF-300, JAPAN). Results: The mean (Standard Deviation) BMI among boys and girls were 18.7 (2.6) and 19.2 (2.8) respectively and the difference was statistically significant (P = 0.000). Multiple linear regression analysis shows that BMI was significantly associated with waist circumference, weight, fat%, total body water (P = 0.000) and fat free mass (P = 0.041) among the boys and inversely associated with height, hip circumference and waist-hip ratio (WHR) (P = 0.000). Among girls, BMI was positively associated with hip circumference (P = 0.035), weight (P = 0.000), fat% (P = 0.000) and total body water (P = 0.000) and inversely associated with height (P = 0.04). Conclusion: Though fat percentage was found to be significantly correlated with BMI, it could explain little of the variation in BMI.Keywords:

A study of relationship between body ingredient and body mass index(BMI) and waist-hip ratio(WHR) is taken based on an investigation of 54 middleaged,well-educated ladies,and measures their height,body weight,BMI,WHR and body ingredient.The experiment reveals that ladies in frequent physical training has weak positive correlations between BMI and body fat percentage,WHR and fat-reduced body weight,strong correlation between WHR and body fat percentage,and weak correlation for the rest(|r|0.4).Conclusions: 1) There's big difference of body fat percentage for the population of the same weight and height,and BMI is not an exact definition of the body fat amount;2) The strong correlation of WHR and body fat percentage reveals the relationship between WHR and body fat amount of middle-aged ladies and their fat distribution character;3) Body fat percentage should be the main index of body fat amount.

The body mass index (BMI) has been the most commonly applied clinical measure to characterise body composition in individuals. However, the BMI has been criticised as being an inaccurate measure of body fatness. Recently, a new index reflecting body composition, the Body Adiposity Index (BAI) was proposed. The BAI was calculated using the equation BAI=((hip circumference)/ ((height)1.5) - 18).The aim of this study was to compare estimates of body fat content, i.e., body adiposity index (BAI), BMI, waist-hip ratio (WHR) and waist and hip circumferences, with respect to their ability to predict the percentage of body fat (PBF).To select an optimal surrogate for adiposity, we examined the correlation between body adiposity percentage as measured by BIA and several variables, including BAI, BMI and WHR. Correlations ranged from a high of 0.78 for BMI, 0.67 for BAI and 0.66 for waist circumference to a low value of 0.39 for the WHR index. The correlation between PBF and BAI (R=0.67, R2=0.45, p<0.001) and the correlation between PBF and BMI (R=0.78, R2=0.60, p<0.001) were of similar magnitude.Based on our results and those of other studies, we can say that the BAI index is not a universally valid index that could be used in the place of the BMI index in a Caucasian population; indeed, it would not accurately reflect body fat mass and thus could lead to an increased risk of obesity. Further, WHR index is not a suitable for an estimation of body fat.

Purpose: -The purpose of the study was to find out relationship of body mass index with fat percentage and waist hip ratio of university boys. Methodology: - The subjects for this study were selected from G.G.V, Bilaspur, Chhattisgarh. A total of 100 university boys were selected. Age of the subjects ranged between 20 to 25 years. Selected Variables were body mass index (BMI), fat percentage (Fat %) and waist hip ratio (WHR). BMI was calculated from body weight and body height (kg/m2), Fat Percentage was measured by OMRON body fat analyzer and WHR was calculated as WC divided by HC. To find out relationship of body mass index with fat percentage and waist hip ratio, descriptive statistics and the Pearson’s Product Moment Correlation was used. Findings: - There exists a significant relationship of BMI with Fat % (r = .903, p > .05) and WHR (r = .611, p > .05).

Introduction: The purpose of this study is to assess the validity of Bioelectrical Impedance Analysis (BIA) to characterize the body fat percentage and its correlation with anthropometric indices. Materials and Methods: The following indices were carried out: weight, height, body mass index (BMI), waist-hip ratio (WHR) taken random samples of 100 subject. The body fat percentages were assessed by bioelectrical impedance analysis. Results: Positive Correlation between body anthropometric indices with body fat. Conclusion: That study concluded that body fat was strong positive correlated with BMI and fair positive correlated with WHR means body fat increased that leads to waist hip ratio and body mass index.

Background : The prevalence of overweight and obesity is on an increasing trend these days. Adverse effect of obesity can be seen in different physiological functions. This study aimed to see the fat distribution among students using different markers of obesity. Methods : A cross sectional observational study was carried out in the Department of Physiology, National Medical College, which included 250 students. Body fat percentage was measured using Omron body composition monitor and waist circumference was measured using non-stretchable tape. Body Mass Index, Body Adiposity Index, Fat Mass and Waist Hip Ratio were calculated. Results : Among 127 male subjects 8.7% were overweight and 18.1%, 47.2%, and 33.1% had high and 7.9%, 15%, 10.2% had very high fat percentage which was obtained from Body Fat Percentage, Body Adiposity Index, and Fat Mass respectively. Similarly, 4.7% and 48.8% had high Waist Circumference and Waist Hip Ratio respectively. Among 123 female subjects 9.8% were overweight and 1.6% were obese. 21.1%, 5.7% and 28.5% had high and 4.1%, and 0.8% had very high fat percentage which was obtained from Body Fat Percentage, and Body Adiposity Index respectively. Also 5.7% and 38.2% had high Waist Circumference and Waist hip Ratio respectively. Conclusion : The study showed high prevalence of overweight and obesity when measured by other adiposity indices than by body mass index.

The purpose of this study was to compare a reliability for obesity between body mass index (BMI) and percent body fat, and to compare a difference of body fat distribution between waist-hip ratio (WHR) and waist circumference (WC) for the discrimination of central obesity and peripheral obesity in adult women. The study included 213 women subjects (aged 37.9±8.3 yrs) who are living in Daegu and Gumi city. Percent body fat, BMI, WHR and WC were demonstrated the useful predictors for the skinfold thickness, body circumferences and obesity in this study. However, the differences of skinfold thickness and body circumference were higher in the comparison between obese and non-obese based upon percent body fat than the comparison between obese and non-obese based upon BMI. Percent body fat showed a higher correlation coefficient with skinfold thickness and body circumference than BMI. Therefore, the reliability for obesity measurement has higher in percent body fat than BMI. In the comparison between WHR and WC for useful measurement of body fat distribution, both WHR and WC were accepted for appropriate indicator of body fat distribution.

This study was carried out to evaluate the associations between lifestyles and Body Mass Index in a group of 349 male and 65 female medical students, ages 17 to 31 years. 20.0% of male students and 3.1% of female students showed the over weight in the classification of obesity by Japan Society for Study of Obesity. There was no statistically significance in the comparison of the height, body weight, body mass index, obesity index and body fat(%) according to grade in both sexes. But male students showed increasing tendency of waist-hip ratio with grade. According to obesity category, there was significant difference in the comparison of body weight, body mass index, obesity index, waist-hip ratio and body fat(%), but height. Body mass index was positively related with waist-hip ratio(r=0.6150, p=0.0001) and fat(%)(r=0.5101, p=0.0001) in males and waist-hip ratio (r=0.4734, p=0.001) and fat(%)(r=0.4522, p=0.002) in females. This study provides an opportunity to further examine the relationship of sociddemographic factors and health behaviors to obesity, and suggest the basic concept to match the obesity study to general epidemiological cohort studies for controlling of chronic adult diseases.
