What do we mean by a BMI? (Body Mass Index)
- BMI is a (ratio of weight/height) proxy measure of medical risk in anorexia
- But they are inadequate as a standalone markers
- BMI is not critical with regards to risks associated with fluids and electrolytes
- The recommendations are that a BMI calculation should be combined with an examination of:- Muscle strength, blood pressure, pulse rate, peripheral circulations and core temperature
BMI must not be a stand alone assessment.
- A BMI does not take into account whether a person is a male or female.
- Neither does it account for a person's age criteria.
- Whilst BMI is an indication to what level an adult may be at in their illness (mild, moderate, severe, critical or life threatening) it would perhaps better to use a child centile growth chart as a more accurate assessment in the case of a younger person.
