What is Body mass index (BMI)

What is BMI ??

Body mass index (BMI) is a measure of body fat based on your weight in relation to your height, and applies to most adult men and women aged 20 and over. For children aged 2 and over, BMI percentile is the best assessment of body fat.

•  Body mass index (BMI) is a measure of relative size based on the mass and height of an individual.

•  The Quetelet Index was devised by Adolphe Quetelet, a Belgian mathematician, astronomer and statistician, in 1832. It was later termed "body mass index" in 1972 by Ancel Keys.

•  BMI is a simple, inexpensive and noninvasive surrogate measure of body fat.

•  Factors such as age, sex, ethnicity and muscle mass are not accounted for in BMI.

•  For adults 20 years and older, BMI is interpreted by using standard weight status categories that are the same for all ages, and for both men and women.

•  For children and adolescents between 2-20 years old, BMI is interpreted relative to a child's age and sex.

•  BMI is a reasonable indicator of body fat for both adults and children.

•  Because BMI does not measure body fat directly, it should not be used as a diagnostic tool.

•  BMI should be used as a measure to track weight status in populations and as a screening tool to identify potential weight problems in individuals.

•  Other measures of body fat, such as skin-fold thicknesses, bio-electrical impedance, underwater weighing and dual energy X-ray absorption, maybe more accurate than BMI.
