The body mass index need to calculate and have children, because obesity is rapidly "younger". However, for young patients are prepared other tables for determining BMI. Different formula for calculating the index and for boys from the age of 12, and girls from the age of 10, since they develop unequally.
Calculating your BMI is very simple, but you need to know fairly accurate indicators of the height and weight of a person at the moment. Measurement is best done in the morning after using the toilet. If you have not determined your height, do it, because this parameter also changes even in adulthood.
To determine the index you will need a calculator. Your height in meters should be squared, that is multiplied by the same number. Weight in kilograms divide by the result. The number that you see is your BMI. For example, if you weigh 65 kilograms and your height is 170 centimeters, the calculations look like this: 65:(1.7h1.7)=22.5.
The world health organization conditionally divides BMI into four main groups:
• Underweight – 18.5;
• Normal weight – 18.5-24.9;
• Overweight – 25 to 29.9;
• Obesity – from 30 and more.
Of course, it is possible to obtain BMI with an indicator of excess weight with small quantity of adipose tissue, but this happens mainly body builders and professional athletes. These people have very developed muscles and its weight is very large, so the index is quite large. The average person score greater than 25 should be cause for concern. In this case, you should immediately adjust your diet and pay more attention to physical education.
The body mass index was developed by Belgian scientist Adolphe Ketele. According to research by doctors from different countries the perfect BMI for men is the indicator 25 to 27, and for women 20-23.
