To meassurement raw skinfold thickness values into a Diabetes and foot ulcers of body mesaurement, population-specific or generalised meashrement are used. These equations measrement derived from empirical relationships between skinfold thickness and body density.
Many equations firstly calculate body density and require an additional calculation to estimate percent body fat. The Brozek et al and the Siri equations can be used for this step:. Body fat values should be generated from published equations which closely match the study population.
It is critical that the equation selected for estimating body fat is appropriate to the demographics of the cohort under investigation e. race, age, and gender. Durnin Womersley developed general equations from a heterogeneous group of varying ages.
Table 1 Durnin Womersley equations for the estimation of body density using 4 skinfold sites. Source [14]. Estimates derived using these equations have been compared to those from the criterion 4-component model see Figures 5 and 6.
Both equations tend to underestimate body fat especially in larger individuals. Similar results have also been observed in men Peterson et al. Source: Peterson et al. However, Slaughter et al. Table 2 lists equations used to determine body composition values in children and adolescents using skinfold measurement.
Table 2 Published equations used to estimate body fat in children and adolescents from skinfolds. Source: Rodriguez et al. Some equations for children and adolescents have been compared with the criterion 4-component modelsee Table 3.
Significant bias for percentage body fat and fat free mass was observed for the equations by Slaughter et al.
No significant mean bias was shown by the equation by Deurenberg et al. This may affect the evaluation of body composition changes within individuals overtime. Correlations were calculated as the correlation between the difference and mean.
FFM values were log transformed to express the difference as a percentage of the mean. Values for percentage body fat are expressed as a percentage of body weight. Adapted from: Wells et al. first 10 days of life and based on different skinfold thickness measuring sites.
The Deierlein et al. A non-significant correlation suggests no bias in the technique across the range of fatness. Source: Clauble et al. However, the relationship between total body density and skinfold thickness varies with age and those equations may not be applicable in younger groups.
Estimates derived using the Slaughter et al. Agreement analysis showed significant bias at 6 weeks, underestimating percentage body fat by 2. The agreement analysis between Slaughter et al. Estimates derived from the Deurenberg et al.
When analysing data in infancy, often the raw thickness data are used. The sum of the thicknesses is determined and internal standard deviation score Z-score are derived. Internal Z-scores can be generated by regressing skinfolds on age and using the saved residualsand then adjusting for sex in the analyses.
The skinfold indices, triceps skinfold-for-age and subscapular skinfold-for-age are useful additions to the battery of growth standards for assessing childhood obesity in infants between 3 months to 5 years. These indices are expressed in percentiles percentage of median and can be assessed by the percentile point achieved by a child relative to the healthy children of that age and gender in the same population.
Median is regarded as a reference value, and 3 rd and 97 th percentiles as thresholds to indicate abnormally low or abnormally high values. The WHO growth standard for triceps skinfold-for-age and subscapular skinfold-for-age are used for interpretation.
Considerations relating to the use of skinfold thickness methods in specific populations are described in Table 6. To obtain reliable data from this method it is essential to standardize the procedure, train the participating staff and assess inter and intra observer reliability to monitor measurement error.

Population specific equations are used to derive estimates of percent body fat. Equipment Caliper The cost of calipers ranges from £9 to approximately £ php Measuring tape Typically a non-stretch fibreglass or plastic measuring tape such as those used in circumference measurements is used to locate the anatomical midpoints on the body where the skinfold measurement is taken.
Protocol Skinfold measurement can be obtained from 2 to 9 different standard anatomical sites around the body using a caliper, as shown in Figure 2. The following are the nine anatomical sites as illustrated in Figure 2 that are most commonly used in the assessment of skinfold thickness: Chest or pectoral skinfold: For men, get a diagonal fold half way between the armpit and the nipple.
Mid-Axillary: A vertical fold on the mid-axillary line which runs directly down from the centre of the armpit. Supra-iliac or flank: A diagonal fold just above the front forward protrusion of the hip bone just above the iliac crest at the midaxillary line.
Quadriceps or mid-thigh: A vertical fold midway between the knee and the top of the thigh between the inguinal crease and the proximal border of the patella.
Abdominal: A horizontal fold about 3 cm to the side of the midpoint of the umbilicus and 1 cm below it. Triceps: A vertical fold midway between the acromion process and the olecranon process elbow. Biceps: A vertical pinch mid-biceps at the same level the triceps skinfold was taken.
Subscapular: A diagonal fold just below the inferior angle of the scapula. Medial calf: The foot is placed flat on an elevated surface with the knee flexed at a 90° angle. A vertical fold taken at the widest point of the calf at the medial inner aspect of the calf.

Biceps: A vertical pinch mid-biceps at the same level the triceps skinfold was taken. Subscapular: A diagonal fold just below the inferior angle of the scapula. Medial calf: The foot is placed flat on an elevated surface with the knee flexed at a 90° angle. A vertical fold taken at the widest point of the calf at the medial inner aspect of the calf. It is standard to take measurements from the right side in the US, and from the left side in Europe. When selecting the side it is important to be consistent. The site to be measured is marked once identified. A non-stretchable tape like in Figure 2 can be used to locate anatomical midpoints on the body. The skinfold should be firmly grasped by the thumb and index finger of the left hand about 1 cm proximal to the skinfold site and pulled away from the body see Figure 3. The caliper is in the right hand perpendicular to the axis of the skinfold and with dial facing up. The caliper tip should be 1 cm distal from the fingers holding the skinfold. The dial is read approx. Measurement is recorded to the nearest 0. Three measurements are recorded and if consecutive measurements differ by 1 mm, the measurement is to be repeated; separated by 15 seconds. The technician should maintain pressure with the fingers throughout each measurement. Measurements should not be taken after exercise as overheat causes a shift in body fluids to the skin and will inflate the skinfold size. As hydration level can influence measurements, it is recommended to carry out the measurements in a hydrated state. Figure 4 An example of a calibration block. It is implemented in large scale population studies or screening purposes, where more portable field methods are desirable. It is the most widely used method of indirectly estimating percent body fat, especially in infants and children. Several equations are available.

Skinfold thickness-for-age indices The skinfold indices, triceps skinfold-for-age and subscapular skinfold-for-age are useful additions to the battery of growth standards for assessing childhood obesity in infants between 3 months to 5 years. Strengths and limitations. An overview of skinfold thickness methods is outlined in Table 5. The majority of national reference data available are for skinfolds at the triceps and subscapular locations. The triceps skinfold varies considerably by sex and can reflect changes in the underlying triceps muscle rather than an actual change in body fatness. Measurement accuracy influenced by tension in the skin Hydration level can influence the measurements. Dehydration reduces the skinfold size. Exercise inflates the skinfold size as overheat causes a shift in body fluids to the skin. Oedema and dermatitis increase the skinfold size. Assumes that the thickness of subcutaneous fat is constant or predictable within and between individuals Assumes that body fat is normally distributed Unable to accurately evaluate body composition changes within individuals overtime. Highly skilled technicians are required Available published prediction equations may not always be applicable to a study population and cross validation in a sub-sample of a study population is required before application of those equations Table 5 Characteristics of skinfold thickness methods.

Population Comment Pregnancy Suitable, but estimates of body fat changes derived from skinfolds are prone to measurement error, especially during pregnancy due to hydration level. Rapid decreases in measurement occur postpartum that are likely attributable to changes in hydration following delivery rather than marked changes in subcutaneous fat Infancy and lactation Suitable Toddlers and young children Suitable Adolescents Suitable Adults Suitable Older Adults Suitable, but presence of oedema may affect estimates Ethnic groups Suitable Other obesity Suitable, but difficult to get reliable measurements, especially in those cases in which skinfold thickness approach the upper limit of the measurement range of the caliper.

The variability of the BIA method may be explained in part by factors related to gender differences in body composition and its influence on the principles of the method. In addition, the error might be strengthened by variations in hydration status that occur in patients with chronic renal disease. Indeed, Woodrow et al. In accordance with other studies [ 10 , 18 , 19 ], we also found similar results of fat content assessed by BIA and SKF when the whole population was analysed. However, the differences became evident when gender was considered. The correlation of BIA measurements with DEXA maintained high in men as well as in women. In addition, similarly to the SKF method, BIA displayed a relatively good agreement with DEXA according to the Bland and Altman plot analysis in the general population. There were no changes in differences of body fat along the measurements range; however, a systematic error in fat measurement for men and women was confirmed. Thus, our results indicate the importance of conducting the comparative analysis of body composition techniques stratifying by gender. More comparative and longitudinal studies would be of great importance for the better understanding of the theoretical and practical basis of body composition analysis. Email: lilian dis.
