Skinfold Body Fat Assessment

Skinfold measurement sites -

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.

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.

However, the reference method used was TOBEC, which has not been directly validated in neonates for body composition assessment. Aris et al. 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.

Table 6 Use of skinfold thickness methods in different populations. 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.

Soinfold measurement is a test measkrement estimates your measuremenr of body fat, measureent is converted into percentage of total body weight. To do it a caliper is used to pinch body fat and measure its thickness on multiple sites of the body. You need to have experience and skill to perform the test correctly. The thickness of these folds is a measure of the fat under the skin, also called subcutaneous adipose tissue. Skinfold thickness results rely on formulas that convert these numbers into an estimate of a person's percentage of body fat according to a person's age and gender.
