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...

...ent body fat cut off values.

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.
