Pattern of BMI among adolescents involved in sports activities

Abstract

World Health Organization's latest projections indicate that globally in 2005, approximately 1.6 billion adults were overweight and at least 400 million adults were obese. World Health Organization further projects that by 2015, approximately 2.3 billion adults will be overweight and more than 700 million will be obese. Body mass index is calculated based on physical measurements such as height and weight. BMI = weight (kg)/height (m)2 National Centre For Health Statistics/CDC -2000 growth charts for children and adolescents aged 2-20 years i.e. BMI for age and sex percentile growth curves are used to classify the subjects as overweight and obesity. The combined prevalence of overweight and obesity is 19.2%. The prevalence of overweight alone is 12.4% and whereas obesity is 6.8%.
