Abstract
Objective: To study the relationship between anthropometric measurements and percent body fat (PBF) in students (17-19 years) and to find the percentage of males and females who are obese using percent body fat cut off values, since Obesity is a predisposing factor for many diseases like Hypertension, Type II Diabetes Mellitus and Coronary Artery Disease.
Methods: Weight, height, Waist Circumference (WC) and Hip Circumference (HC) of 93 students in AIMS (38 males and 55 females) were measured. PBF obtained by Bioelectric Impedance Analysis. Body Mass Index (BMI) and Waist-hip ratio (WHR) calculated. Correlations studied between weight, height, BMI, WC, HC, WHR and PBF.
Results: Significant positive correlations obtained between weight, BMI, WC, HC and PBF. WHR and PBF showed significant correlation only in males. There was no significant correlation between height and PBF .By multivariate linear regression analysis, BMI, HC and weight explained 83.8% variation of PBF in males and BMI, height and WHR 91.8 % variation in females. Percentage of males and females who were obese was 18.42% and 30.91% respectively.
Conclusion: No significant differences by gender for any of the correlations except WHR. More females are obese than males. Further studies including more parameters and greater sample size required for more insight in Obesity research.
Key words: anthropometric measurements, percent body fat, correlation
INTRODUCTION:
Obesity and its associated complications in adolescents is a problem of great concern especially in developing countries like India. Diseases such as Hypertension and Type II diabetes are now-a-days seen in younger individuals. In clinical practice BMI is the most...

From the present study we conclude that there were no significant differences by gender for any of the correlations except waist-hip ratio. This may be due to the differences in the pattern of distribution of fat in males and females. Including greater sample size, adolescents of other age groups and also evaluation of more parameters like dietary habits, sedentary behavior etc. will give more insight in the area of obesity research. Since adolescents who are obese often experience significant social pressure, stress and difficulties accomplishing developmental tasks in addition to the health problems, control and treatment of obesity is mandatory. So school-based interventions to promote healthful nutrition and physical activity in adolescents especially girls should be undertaken20 to help adolescents maintain optimal body weight.
Child obesity became a very serious issue that is taking on the health of the nation 's children. It is everyone responsibility to work on preventing and reducing childhood obesity, from the parents who are suppose to care about their children’s health, to the public health representatives, who should care about a future healthy nation, and everyone in between. Every part of society should create a set of lifestyle changes in order to save our kids from obesity. There are many aspects, which have to be changed or improved, including parent’s nutrition education, children’s physical activity and kid’s nutrition in a school and home, food industry and etc.
As for the gender that is most likely to suffer from morbid obesity is the female gender. As a treatment for now the first step is surgery to try and reduce the obesity also some medical surgeries also involve is minimizing the size of ones stomach. Also according to the panel, FDA guidelines for approval of obesity drugs might well be altered to give less importance to metabolic biomarkers (blood pressure, triglycerides, cholesterol) and more to the loss of adipose tissue itself or particular deposits of adipose tissue that have deleterious effects on many physiological functions (Allison, 2008).
Nearly two-thirds of the United States population is overweight. There are several ways to determine if a person is obese or overweight. Experts say that a person’s body mass index is the best way to determine an adults weight in relation to their height. A BMI from 18.5 to 24.9 kg/m2 is considered normal, adults with a BMI of 25 to 29.9 kg/m2 are considered overweight. There are exceptions with peoples BMI, an athlete can have a high BMI and not be overweight or obese. Adults with a BMI of 30 kg/m2 or higher are considered obese. A person with a high BMI can have a normal amount of body fat if they have more muscle tissue. However, the risk of death and disease is increased for adults who are overweight and obese (Kolata 1)
Obesity is a global problem (Tremolieres 1973; WHO 2000) (6). It increases numerous health risks including coronary heart disease, hypertension, stroke (WHO 2000) (7) and is a major risk factor for musculoskeletal pain (Nantel, Mathieu and Prince, 2011) (8) and osteoarthritis of weight bearing joints (WHO 2000; Felson et al, 2000) (9). Obesity rates are growing high every year and in the last 15 years twofold increase is recorded (10). Obesity is categorised on body mass index (BMI). Body mass index is used to measure obesity and is calculated by dividing a person’s weight (in kilograms) by the square of their height (in metres). Overweight is taken as BMI of 25 to 29.9kg/m2 and BMI...

Obesity in the United States continues growing alarmingly. Approximately 66 % of adults and 33 % of children and teenagers in the US are overweight. Obesity is the result of fat accumulated over time due to the lack of a balanced diet and exercise. An adult with a BMI (body mass index) higher than thirty percent is considered obese (Whitney & Rolfes, 2011, pg. 271).
The first component of the MUST involves measuring the patient’s height and weight to establish their Body Mass Index (BMI). BMI is the’ relationship b...
According to the U.S. Centers for Disease Control and Prevention (CDC,) there were 90.6 million obese individuals in 2010 (Ogden, Carroll, and et al). This represents approximately 36% of the total population. In 2010, it was determined that out of the 36% of obese person...
Although many individuals are uncertain about the increasing statistics associated with obesity, more than seventy percent of men and virtually sixty-two percent of women within the United States adult population are overweight or obese (Wilmore, Costill, & Kenney). Obesity refers to the condition of having an excessive amount of body fat. If an individual’s amount of body fat becomes too excessive, he/she is at a much greater risk of developing life-altering diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, etc. (Wilmore, et al., 2008).
According to the 1999-2000 National Health and Nutrition Examination survey says that, 16 percent of children around the ages of 6-19 years old are at risk of being obese. Obesity has increased in the last twenty years now. Obesity is like other disease, it impairs the normal body functioning. Children who are overweight have excess fat tissue that caus...

There are different ways to determine your body composition and the risks that they involve. In this lab, body measurements are taken to find the body percent fat, waist-to-hip ratio, body mass index (BMI), and basal metabolic rate (BMR). Skin folds for the chest, abdomen, and thigh were taken for males, and triceps, iliac crest, and thigh for females. Age, height, and weight for each person were recorded as well as the waist and hip circumference.
The statistics showed that around 31% of women are obese compared to around 18% men.7 Women are more affected by obesity due to lifestyles. The inaccessibility of safe side walks, cultural and social factors, taking care of kids are some of the reasons that play a vital part...
Obesity occurs in all countries and it is one of the gravest problems in modern society. Obesity problems have become one matter of concern for individuals all around the world. What is more is that Obesity rates continue to rise all around the world. One of the chief causes is unhealthy diets. Obesity is also due to lack of exercise and lack of education and awareness. Therefore obesity has various effects including the risk of suffering from a range of health conditions, increased expenditure on health care and lack of self-esteem.
