As part of ongoing growth studies, 20 duplicate sets of eight . It is well known that the measurement error of skinfolds is relatively high compared with that of other anthropometric traits, and largely depends on the experience of the observer.
The intra-observer technical error of measurement (TEM) was between 0.12 and 0.47 mm for skinfold thickness and between 0.09 and 1.24 cm for circumference measurements.

Womersley J , Durnin JV Hum Biol , 45(2):281-292, 01 May 1973 Developing a tool for obtaining maternal skinfold thickness measurements and assessing inter-observer variability among pregnant women who are overweight and obese Lavern M Kannieappan , 1, 2 Andrea R Deussen , 1, 2 Rosalie M Grivell , 1, 2 Lisa Yelland , 1, 2 and Jodie M Dodd 1, 2 Both intra- and inter-observer variability of skinfold thickness (triceps, subscapular, biceps, suprailiac) and circumference (neck, arm, waist, hip) measurements were investigated in five . Therefore the purpose of this study was to establish a standardised tool for the assessment of skinfold thickness measurements for the purpose of determining body fat percentage, and to evaluate the inter-observer variability in assessing body composition in this group of women.

Developing a tool for obtaining maternal skinfold thickness measurements and assessing inter-observer variability among pregnant women who are overweight and obese BMC Pregnancy Childbirth . 2013 Feb 19:13:42. doi: 10.1186/1471-2393-13-42.Skinfold thickness are typically recorded in mm. Some calipers record in both mm and cm. The skinfold thickness values should be quality checked during data processing in the same manner as other health related variables, for example by checking for outliers and data entry errors.. Raw skinfold thickness values are often used and they act as reliable indicators of regional fatness.
You can measure your skinfolds using a caliper, a device utilized to measure an object's thickness or diameter. To take skinfold measurements with a body fat caliper, follow the listed steps: Pinch the skin at the location of your choice using your thumb and index finger of your one hand.; Gently pull the skin away from the muscle; the fold should be around 1 .
To elucidate the impact of the observer's level of technical knowledge, training and experience with measuring height and triceps skinfold thickness on the reliability of these measurements in .The National Center for Health Statistics pooled skinfold thickness measurements of some 20,000 children age 1 to 17 yr in the United States and developed smoothed percentiles to serve as reference data to describe the skin fold thicknesses of American children and adolescents. The National Center for Health Statistics pooled skinfold thickness measurements of some . The mean skinfold thickness values in both sexes according to the birth weight group is shown in Table 7. The mean skinfold thickness increased progressively from the smallest birth weight group to the highest in both sexes. (<2500 g) to the largest (≥4000 g) – p-value from ANOVA was consistently <0.001. The mean birth weights of males and .
The measurement of the skinfold thickness at various sites with the calipers has remained the traditional method for estimation of body fat percentage (%BF) in clinical practice. Although this technique is relatively inexpensive and easy to learn, there are more chances of errors while measuring the skinfold thickness by this method.Variation in pinch size is an important source of TEM that can affect the reproducibility of skinfold thickness measurements and interfere in the estimation and classification of the molecular and tissue component of body adiposity. Skinfold thickness measurements have been advocated as an important supplementary criterion of change in behavior therapy of the obese. This paper describes technical procedures for obtaining reliable data from four body sites and provides a summary of validated and extrapolated norms for converting skinfold data to percentage body fat in males .
TEM is the standard deviation between repeated measurements taken independently by one observer (intra-observer) or between measurements performed by multiple anthropometrists (inter-observer) . It uses the same units as the variable under consideration and can be employed in the calculations of confidence intervals [ 22 ].The Measurement of Human Growth. Noël Cameron, in Human Growth and Development (Second Edition), 2012. 19.5.6 Skinfolds (Harpenden 20, Holtain or Lange Calipers 22,23). The technique of picking up the fold of subcutaneous tissue measured by the skinfold caliper is often referred to as a “pinch”, but the action to obtain the fold is to sweep the index or middle finger . Measuring skinfold thickness is an inexpensive, simple and non-invasive method. . The intra-observer error, calculated from the difference between 116 duplicate measurements over all observers . The aim of this study was to verify the effect of pinch size on skinfold thickness measurement and the consequent interference in the estimation and classification of body adiposity components.

Calculating Percent Body Fat Using Skinfold Measurements. You can measure body fat percentage using a variety of different approaches. One of the most common methods involves determining the thickness of subcutaneous fat. The approach recommended by Jackson, A.S., Pollock, M.L., and Siri et al. can be used to accurately calculate percent body fat.
