What Is The Standard Error Of Estimate For Skinfold Measurement


For assessment of whole body lean mass, both skinfold measurements and BIA have limitations. They develop several formulas based upon a quadratic relation and the function of age. (Jackson and Pollock, 1978) The following formula is one of Jackson and Pollock's that has been used A second problem is that FM discerned by MRI is only that present in adipose tissue.

Predictive error in individuals is high, even when using population specific equations. Thus all techniques suffer from two types of error: methodological error when collecting raw data, and error in the assumptions by which raw data are converted to final values. Brook C G D. However, although widely used, particularly in the USA, problems with accuracy have received insufficient attention.

If each test is performed correctly according to the recommended guidelines, there is a +/- 3% error. Standard error of estimate ... Arch Dis Child 197550142–145.145 [PMC free article] [PubMed]3. Because bone and muscle are more dense than water, a person with a larger percentage of fat free mass will weigh more in the water and have a lower percent body

No significant difference was found between the seven site skin fold method and the abdominal circumference method. Air Displacement Plethysmography By measuring the resistance to the current, the machine estimates the percent body fat. To determine body composition measurements using a newly developed skinfold ...

The abdominal circumference method, on the other hand, underestimates BF when the subject is above average BF according to the seven site method. Human Kinetics Books: Champaign, IL ISBN O-87322-121-4. 1998. The technique has better precision than hydrodensitometry in children,31,32 and is acceptable in children as young as 4 years.

Estimating body composition from skinfold thicknesses and bioelectrical impedance ... This variability is partly explained by the process of chemical maturation that occurs before adulthood,30 but interindividual variability is also significant, even in healthy children.23Traditionally, body volume was measured by hydrodensitometry; They also noted that pulling the tape too tight would compress the underlining soft tissue making the measurement inaccurately smaller. (Katch and McArdle, 1983) A simple formula using an abdominal circumference A double pinch technique (demonstrated below) can be used to aid in performing the assessment properly.

Such assumptions may largely hold true for healthy subjects but are more problematic in patients who may have deranged body composition or hydration. The tester pinches the skin at the appropriate site to raise a double layer of skin and the underlying adipose tissue, but not the muscle. calculated by standard error of measurement, ... The ongoing epidemic of obesity in children and adults has highlighted the importance of body fat for short term and long term health.1 However, other components of body composition also influence

at a body composition as a precise measurement, but as an estimate within a ... According to Aristizábal et al (2007), skinfold thickness equations showed poor validity for body fat assessment as the equations showed significant differences and lower correlation coefficients with hydrodensitometry. For this reason it is suggested that skinfold be used for those of healthy weight ranges rather than the overweight and obese populations. When circumference and bone breadth were added to skinfold measures the accuracy improved based on the validity of dual x-ray absorptiometry.
