Obesity can be measured by a calculation of BMI, namely Body Mass Index, which equals a person's weight in kilograms divided by their height in meters squared. Obesity in children and adolescents is defined as a BMI greater than the 95th percentile. Last week, a brand-new survey was carried out around the city via questionnaires accompanied with telephone interviews. The obesity questionnaire can help people find out whether they are on the threshold to obesity or are already obese and how to overcome this disorder which can have far reaching consequences on their health.
