Eur J Clin Invest 2012; 42 (9): 961–966 Abstract Background The contours of a human body are determined by the volumes of the underlying tissues [adipose tissue (AT), muscle, bone and viscera]. Conceptually, they are assumed to be used as a concentric set of cylinders. Determination of these clinically applied circumferences in terms of relative tissue proportions has led to conflicting results. As it remains unclear what a circumference really measures or represents and how it relates to body composition (BC), the aim of this study was to determine the content of the circumferences and whether these perimeters can be used to assess segmental or whole body tissue components. Design Subsequent to an anthropometric protocol, the five white Caucasian cadavers were fractionated into slices of 3 cm and segmental and whole BC was determined at the anatomical tissue‐system level by direct dissection. Results Only two circumferences correlated significantly with their dominating component [upper arm circumference ( r = 0·98; P < 0·01) and waist circumference (WC) ( r = 0·90; P < 0·05) with AT]. Two circumferences were related to a segmental tissue component [WC ( r = 1·00; P < 0·001) with muscle mass of the trunk and wrist circumference (WrC) ( r = 0·90; P < 0·05) with bone mass of the upper limb]. Two circumferences were related to a whole body tissue component [chest circumference ( r = 0·90; P < 0·05) with whole body AT mass and WrC ( r = 0·90; P < 0·05) with whole body bone mass]. Conclusion The clinically applied circumferences do not measure what they pretend to measure. Of all the studied circumferences, only 2 circumferences (WC and WrC) can be used to assess segmental or whole body tissue components.
