[Bioimpedance analysis in determining body composition. Testing of a new simple apparatus]

In the assessment of human body composition, only expensive and time consuming methods have hitherto been available. Recently, the new bioimpedance method has been introduced. It offers an easy, quick, inexpensive and noninvasive measurement with an accuracy comparable to that of the classical methods. A new inexpensive Danish apparatus was tested against the most used and validated equipment. Fifteen normal subjects underwent measurements with both apparatuses. The two methods gave identical results with a coefficient of correlation of 0.99 and a coefficient of variation of 5.6%. The apparatus can be recommended for clinical and scientific purposes.
