Weight and height percentiles are determined by growth charts and body mass index charts to compare a child's measurements with those of other children in the same age group. By doing this, doctors can track a child's growth over time and monitor how a child is growing in relation to other children.

WHO parameters for BMI-for-age parameters are defined by standard deviations and describe overweight to be greater than +1standard deviation from the mean (equivalent to BMI=25 kg/m2 at 19 years) and obese as +2 standard deviations from the mean for 5 to 19 year-olds (equivalent to BMI=30 kg/m2 at 19 years).

Compared to traditional metrics, such as the body mass index (BMI), (which uses weight and height), BRI may improve predictions of the amount of body fat and the volume of visceral adipose tissue. Despite its common use, BMI can misclassify individuals as obese because it does not distinguish between a person's lean body mass and fat mass ...
In statistics, a k-th percentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls ("exclusive" definition) or a score at or below which a given percentage falls ("inclusive" definition); i.e. a score in the k-th percentile would be above approximately k% of all scores in its set.
Obesity and BMI An obese male with a body mass index of 53 kg/m 2: weight 182 kg (400 lb), height 185 cm (6 ft 1 in). Obesity classification is a ranking of obesity, the medical condition in which excess body fat has accumulated to the extent that it has an adverse effect on health. [1]
Body mass index (BMI) is a useful quantification that can gauge level of obesity. It is defined as follows with the given clinical ranges. = / [()] Obesity: BMI > 95th percentile; Overweight: 85th < BMI < 95th percentile; Underweight: BMI < 5th percentile
Body fat can be estimated from body mass index (BMI), a person's mass in kilograms divided by the square of the height in meters; if weight is measured in pounds and height in inches, the result can be converted to BMI by multiplying by 703. [26] There are a number of proposed formulae that relate body fat to BMI.
