Consultant Pediatrician, Endocrinology and Diabetes at King Abdulaziz University in Jeddah, Professor Abdul Moeen Eid Al-Agha, revealed that females and adult males share 4 names and ranks during the obesity stage. As for children and adolescents, there are no names in the Arabic language dictionaries for their different levels of obesity, and the BMI scale is the most acceptable method for defining and classifying obesity, as it is calculated by dividing the weight (in kilograms) by the square of the height in metres.
