KINS 2295 Lecture Notes - Body Water, Sarcopenia, Ct Scan
Document Summary
The criticisms of height-weight tables: tables do not consider body composition, most data come from white, middle class us adults age 25-29. American population: no accepted method has been devised to determine frame size. Density of nonfat compartments varies as function of age sex and racial groups. Conclusion- densitometry should not be used as a universal criterion for prediction of percent fat. Equations on four component models are preferred over equations based on a two component model. Criticism: bmi does not take body composition into account. Waist circumference to hip ratio is a better predictor of obesity related health risk than bmi. The relationship exists between fat located in the depots directly under the skin and internal body fat and body density. Use sum of number of skinfolds as an indication of relative fatness among indivuals. Use fatfolds in conjuction with equations or tables to predict percent body fat. Proper identification of measurement site and proper measurement technique.
