Body weight ( Berat Badan ) & Ideal body weight (Berat badan ideal)

Posted by chikmie  |  No comments

From Wikipedia, the free encyclopedia
The term body weight is used colloquially and in the biological and medical sciences to refer to a person's mass or weight. Body weight is measured in kilograms, a measure of mass, throughout the world, although in some countries such as the United States it is measured in pounds, or as in the United Kingdom, stones and pounds. Most hospitals, even in the United States, now use kilograms for calculations, but use kilograms and pounds together for other purposes. Strictly speaking, the body weight is the weight of the person without any items on, but practically body weight is taken with clothes on but often without the shoes and heavy accessories like mobile phones and wallets. Body weight is one way of determining a person's health.

While the terms mass and weight are often used interchangeably in the context of body weight, they actually refer to separate but related concepts in physics. Mass is a measure of an object's inertia and is independent of the effects of gravity, while weight is a measure of the force due to gravity. Thus, if a person were to travel from Earth to the Moon, where there is less gravity, their mass would remain unchanged but their weight would decrease.

Ideal body weight

Ideal body weight (IBW) was initially introduced by Devine in 1974 to allow estimation of drug clearances in obese patients; researchers have since shown that the metabolism of certain drugs relate more to IBW than total body weight.[1] The term was based on the use of insurance data that demonstrated the relative mortality for males and females according to different height–weight combinations. The most common estimation of IBW is by the Devine formula; other models exist and have been noted to give similar results.[1] Another method of estimating ideal body weight is using the body mass index.
