Body Mass Index (BMI) and Weight Loss Tips

Body mass index (BMI) is a measure of association between mass and size of an individual devised by the Belgian statistician Adolphe Quetelet, so it is also known as the Quetelet index.

It notes that you can not apply the same values of BMI in children and adolescents because of their constant natural growth and body development so that a BMI is obtained regarding their age and sex.

So first you must first have the date of birth and measurement for the calculated age and be more accurate to categorize this age group.

After BMI is calculated with the same formula as for adults, after calculated BMI for this age group, the BMI value is compared in growth charts CDC BMI-for-age for both boys and girls respectively for percentile category. These percentiles are a measure of dispersal that is used most often to assess the size and growth patterns of each child in the United States because they are less likely to present extreme values and therefore errors in the ranges of values . The percentile indicates the relative position of the child’s BMI number among children of the same sex and age. Growth charts show the level of weight categories used with children and adolescents (underweight, healthy weight, overweight and obese).
