9. Evaluating the results

Body mass index
The Body Mass Index (BMI) is a figure that is commonly used to evaluate body weight. The figure is calcu-
lated from body weight and height. The formula is:
Body mass index = body weight ÷ height
weight is classified for adults (20 years and over) using the following values:
Category
Underweight
Normal weight
Overweight
Obese (overweight)
Source: WHO, 1999 (World Health Organization)
Body fat percentage
The subsequent body fat percentages serve as a guideline (for further information ask your doctor).
Male
Age Low Normal
10-14 <11% 11-16%
15-19 <12 % 12-17%
20 – 29 <13% 13-18 %
30 – 39 <14% 14-19 %
40 – 49 <15% 15 – 20% 20.1 – 25% >25%
50 – 59 <16% 16 – 21% 21.1 – 26% >26%
60 – 69 <17% 17 – 22% 22.1 – 27% >27%
70-100 <18 % 18 – 23% 23.1 – 28% >28%
A lower value will often be determined in the case of athletes. Depending on the sporting activities per-
formed, the training intensity and the physical constitution, the results may still be below the stated stand-
ard values. Please note, however, that there may be a risk to health in the case of extremely low values.
Body water content
The body water content in % is normally within the following ranges:
Male
Age Poor
10-100 <50 %
Body fat contains relatively little water, therefore body water content may be below the standard values in
persons with a high body fat percentage. On the other hand, endurance athletes may exceed the standard
values due to having low levels of fat and a high muscle percentage.
The body water calculation performed using this scale is not suitable for drawing medical conclusions,
for example in the case of age-related water retention. Consult your doctor where necessary. A high body
water content is generally desirable.
