4. 2. Human body composition. Reference data and anthropometric equations. The metabolic syndrome and risk

   Author : Ingrid Larsson; Göteborgs universitet; []
   Keywords : adults; anthropometry; atherosclerotic morbidity; body composition; body fat; cardiovascular disease; DEXA; dual energy x-ray absorptiometry; fat-free mass; FFM; humans; metabolic syndrome; morbidity; mortality; prediction equations; randomly selected sample; reference data; sagittal trunk diameter; TBK; total body potassium; waist circumference;

   Abstract : The determination of body composition is a key to the understanding of the relation between obesity and disease. In order to evaluate body composition data, reference values are needed. Since methods with high validity and reproducibility are expensive and often time consuming, simpler techniques based on anthropometry are needed. READ MORE
