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 are

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 Organisation for Research and Treatment of Cancer (EORTC) database.
