Body Mass Index Categories
Classification of weight for adults over 18 years on the basis of Body Mass Index
according to WHO, 2000 EK IV and WHO 2004 (WHO - World Health Organization).
6 Weighing with BSA
- Values for Body Surface Area (BSA) is the measured or calculated surface area of a
human body. For many clinical purposes, BSA is a better indicator of metabolic mass
than body weight because it is less affected by abnormal adipose mass. BSA is
commonly used in medicine, particularly to calculate doses of chemotherapeutic
agents and index cardiac output.
Average BSA for children of various ages, for men, and for women, are taken to
be:
Age BSA
Neonate (newborn) 0.25 m²
Child of 2 years 0.5 m²
9 years 1.07 m²
10 years 1.14 m²
12-13 years 1.33 m²
Women 1.6 m²
Men 1.9 m²
There was an average BSA of 1.73 m² for 3,000 cancer patients from 1990 to 1998 in a European
Organization for Research and Treatment of Cancer (EORTC) database.
During 2005, there was an average BSA of 1.79 m² for 3,613 adult cancer patients in the UK. Among
them, the average BSA for men was 1.91 m² and for women was 1.71 m².
However, there is some evidence that BSA values are less accurate at extremes of height and weight,
where Body Mass Index may be a better estimate.

1. Starting with BMI process
2. When BMI, weight and height is playing rotationally.
