Skinfold Body Fat Assessment

Body density evaluation techniques -

This method, also known as underwater weighing or hydrodensitometry, estimates your body composition based on its density 9. This technique weighs you while submerged under water after exhaling as much air as possible from your lungs.

You are also weighed while you are on dry land, and the amount of air left in your lungs after you exhale is estimated or measured. All of this information is entered into equations to determine the density of your body. Hydrostatic weighing is an accurate way to assess your body fat.

Similar to hydrostatic weighing, air displacement plethysmography ADP estimates your body fat percentage based on the density of your body 9. However, ADP uses air instead of water. The relationship between the volume and pressure of air allows this device to predict the density of your body You sit inside an egg-shaped chamber for several minutes while the pressure of the air inside the chamber is altered.

To obtain accurate measurements, you need to wear skin-tight clothing or a bathing suit during testing. The Bod Pod is the main ADP device currently used. It predicts your body fat with air rather than water. BIA devices detect how your body responds to small electrical currents. This is done by placing electrodes on your skin.

Some electrodes send currents into your body, while others receive the signal after it has passed through your body tissues. Electrical currents move through muscle easier than fat due to the higher water content of muscle BIA devices work by sending small electrical currents through your body to see how easily they travel through your tissues.

Many different devices are available, although advanced devices produce more accurate results. BIS and BIA devices look similar but use different technology.

BIS uses a much larger number of electrical currents than BIA, in addition to high and low frequencies, to mathematically predict your amount of body fluid BIS also analyzes the information differently, and some researchers believe that BIS is more accurate than BIA 14 , However, similar to BIA, BIS uses the body fluid information it gathers to predict your body composition based on equations The accuracy of both of these methods depends on how similar you are to the people for whom these equations were developed However, BIS uses more electrical currents and processes the information differently.

However, while BIA and BIS send currents through your whole body, EIM sends currents through smaller regions of your body These devices are placed on different parts of the body to estimate the body fat of those specific areas Because this device is placed directly on specific body regions, it has some similarities to skinfold calipers, although the technologies are very different.

EIM injects electrical currents into small body regions. Portable devices are placed directly on different body parts to estimate the body fat percentage at those locations. More research is needed to establish the accuracy of this method.

For some devices, you stand on a rotating platform for several minutes while the sensors detect your body shape. Other devices use sensors that rotate around your body. In this way, 3-D body scanners are similar to circumference measurements.

However, a greater amount of information is provided by a 3-D scanner The method uses information about your body shape to predict your body fat percentage. More information is needed about the accuracy of these methods. Multi-compartment models are considered to be the most accurate method of body composition assessment 3 , These models split the body into three or more parts.

The most common assessments are called 3-compartment and 4-compartment models. These models require multiple tests to get estimates of body mass, body volume, body water and bone content For example, hydrostatic weighing or ADP can provide body volume, BIS or BIA can provide body water and DXA can measure bone content.

We highlight that body composition analysis and the accuracy of methods should be stratified by gender especially in older adults. Durnin and Womersly SF equation adopted in this study is one of the most used and accurate method to evaluate body fat [ 10 , 11 , 12 , 31 ].

Age, sex and obesity are important factors in terms of SFs and body density measures, since the same SF level at different ages may be associated with changes in the fat distribution pattern [ 31 ].

Hence, it is likely that the individuals with higher body fat percentage have high amount of internal fat that were not detected by SF measurements, which could have led to the underestimation by SF equation [ 31 ].

The Bland and Altman approach [ 28 ] used in our analyses to estimate the average difference and concordance limits between two BF methods has also been used in previous studies [ 37 ], wherein it was stated that the use of correlation coefficients may not be appropriate, as a high correlation may not reflect a high level of concordance [ 28 , 37 ].

One possible limitation that could also be stated relates to the generalizability of the findings, due to our sample not being nationally representative. Another potential limitation of our study could be attributed to the fact that the SF assessment is very difficult especially in older adults.

However, in order to minimize such errors, we adopted the following strategies: use of good quality skinfold caliper, all anthropometrics were extensively trained in volunteer older adults, measures were taken three times and we provided previous orientation about hydration status.

BIA and SF equation showed a strong level of concordance to estimate body fat percentage in all participants and among women when compared to our standard reference i. A strong level of concordance was observed between DXA and the anthropometric equation developed by Durnin and Womersley in men, while BIA had a moderate concordance in this group.

Future research in older adults should consider various methods, different ethnic groups and the development of new SF equations. NCD Risk Factor Collaboration NCD-RisC L, Abdeen ZA, Hamid ZA, Abu-Rmeileh NM, Acosta-Cazares B, Acuin C, et al.

Adapted from 1. Like the waist circumference, the waist-to-hip ratio WHR is also used to measure abdominal obesity. Equations are used to predict body fat percentage based on these measurements.

BIA equipment sends a small, imperceptible, safe electric current through the body, measuring the resistance. The current faces more resistance passing through body fat than it does passing through lean body mass and water. Equations are used to estimate body fat percentage and fat-free mass.

Individuals are weighed in air and while submerged in a tank. Fat is more buoyant less dense than water, so someone with high body fat will have a lower body density than someone with low body fat.

This method is typically only used in a research setting. This method uses a similar principle to underwater weighing but can be done in the air instead of in water.

Muscle tissue contains a high dvaluation content which densitj the electrical current to pass through quickly, however the electrical current experiences resistance when passing through fat tissue.

Single frequency BIA scales are typically used allowing only TBW to be measured, however if multiple frequency scales are used, this can be further differentiated into extracellular water and intracellular water.

ISAK stands for the International Society for the Advancement of Kinanthropometry who train practitioners to perform skinfold measurements in dennsity standardised way. The skinfold technique measures a double fold of skin, which reflects the subcutaneous fat thickness at various sites across the body.

Skinfold thickness is measured in mm, and various population-specific equations have been created to attempt to convert these measures into body fat percentage. Skinfolds are best used as a monitoring tool over time, with the same person taking the measurements each time. The thickness of a skinfold also depends on hydration status.

So although this method is relatively easy there are also quite a few limitations. Air displacement plethysmography measures vensity composition through a person sitting within an enclosed chamber i.

Bodpod whereby body volume is indirectly measured through measuring the volume of air the body displaces within the chamber.

In other words, the amount of air that you displace when stepping in the chamber is equivalent to your body volume. Volume, in addition to body weight, can then be used to calculate body density, which then allows FM and FFM to be estimated.

This technique involves being fully submerged in a tank of water and expelling all air in the lungs whilst underwater weight is measured.

Both bone and muscle have a greater density than water, whereas fat mass has a lower density than water.

Therefore, someone with a larger amount of FFM will weigh more in water. Body density is calculated using underwater weight, body weight outside of the water, density of the water and residual volume of the lungs. The residual volume in the lungs is measured by inhaling helium and measuring the dilution.

Estimations of FM and FFM can then be made. This technique is perhaps the most direct and accurate technique to measure body fat, but there evluation few places that have this facility and it is not a very practical method.

There are a number of techniques that can be used to measure body composition. The technique we should use depends on the goal of the measurement. For example, if we want to know more about bone density, we should use DXA. If we need an accurate measure of body fat, we cannot use skinfold measurements and we should use underwater weighing or DXA.

On the other hand, if we need a practical way to track changes over time, we should consider skinfolds. The different techniques vary in their accuracy and their reliability how reproducible the results are if you do several measurements. This will be discussed in the next blog.

Measuring Obesity

Most DEXA systems have adjusted for this process see Heymsfield Different conversion factors also exist for the derivation of total body water mass from labelled water dilution volumes. Each equation takes a different strategy to derive soft non-osseous mineral mass.

Non-osseous minerals, glycogen and other residual mass components are taken into account. Considerations relating to the use multi-component models in specific populations are described in Table 4.

Multi-component models. What is assessed? How is the measurement conducted? When is this method used? How are estimates of body composition derived?

Strengths and limitations Populations Further considerations Resources required Instrument library References Instrument library. This model requires the following data: Body mass Body volume from densitometry e. under water weighing or air displacement plethysmography Total body water stable isotope dilution analysis or bioelectrical impedance analysis The 4-component 4C model further divides fat-free dry mass into protein and bone mineral content BMC.

Table 1 Summary of differences between 2-, 3-, and 4-component models. Model Components Measurements needed Assumptions relating to composition 2-component model 1. Fat mass 2. Water 3. Protein 4. weight, height, skinfolds, circumference measurements and their combination in prediction models.

As different body composition measurement techniques are required to calculate multi-component models, their use is restricted in large-scale population studies, in clinical practice and in field settings.

Taking into account the various assumptions underlying the densities and constant ratios protein-to-mineral ratio in the 3C model; and the bone mineral content to non-osseous mineral ratio in the 4C model , fat mass can be estimated from the combined measurements of: Body mass Body volume from densitometry hydrostatic underwater weighing or air displacement plethysmography Total body water isotope dilution or bioelectrical impedance The above measures are combined using the formulae in Table 2.

The body mass residual described in approach 1 is assumed to be a single combined residual mass e. protein, non-osseous minerals and other constituents like glycogen of known density.

Table 2 Selection of multi-component models to estimate overall body fat mass. Strengths and limitations. An overview of multi-component models is outlined in Table 3. Strengths Multi-component models address variability in fat-free mass by providing information on hydration, density and mineralization of fat-free mass, this is especially important in those populations who deviate from the fixed constants assumed in 2C models e.

Limitations Each component of the models incurs a separate cost for collection and data processing; the more components measured, the higher the final cost. Lack of accessibility of the different equipment used to assess the various components.

The techniques require a multitude of expertise in collection and analysis and therefore may be suitable for a research setting but not within the practicalities of a clinical setting.

Significant differences found in bone mineral content estimates between DEXA systems resulting in differences within the prediction models. For instance when comparing GE Lunar iDXA to Hologic Discovery A. The two estimates of bone mineral mass are highly correlated R 2 , 0.

The between-manufacturer mean difference in bone mineral estimates has been found to lead to a 0. A whole body composition method only; it is not able to provide information on regional distribution of tissue or depots.

The assessment of bone mineral content by DEXA uses ionising radiation and is therefore not appropriate for measurements during pregnancy. Table 3 Characteristics of multi-component models.

Additionally, it is important to follow standardized guidelines and testing procedures when using the SKF technique. The personal trainer is referred to the Anthropometric Standardization Reference Manual Harrison et al. However, with the popularly used generalized equations by Jackson and Pollock and Jackson, Pollock and Ward , follow the guidelines presented in Table 2.

For consistency with your clients‘ measurements, make sure you monitor your their changes using the same calipers.

Most SKF measurements use two to three SKFs to predict body density Db , from which body fat can be derived using the appropriate equation. However, for higher precision, SKF prediction equations that take into account a client’s age, gender, ethnicity, and physical activity level are recommended.

Heyward and Stolarczyk provide specific SKF equations based on the factors cited above. Your clients will have variation in skin thickness, compressibility of adipose tissue, and hydration level, which will affect the SKF measurement. Keep a record of these observations for follow-up assessements.

Exercise also increases the extracellular water accumulation in the subcutaneous tissue and thus will increase skinfold thickness. Therefore, SKFs should not be measured immediately after exercise, especially in warmer environments.

Skinfold Measurement Procedures. The following procedures will increase your reliability and precision when doing SKF measurements Harrison et al. Take all SKF measurements on the right side of the body. Carefully identify, measure and mark the SKF site. Grasp the SKF firmly between the thumb and index finger of your hand.

The fold is lifted 1 cm above the site to be measured. Lift the fold by placing the thumb and index finger 8 cm ~3 inches apart on a line that is perpendicular to the long axis of the skinfold. The long axis is parallel to the natural cleavage lines of the skin.

For individuals with extremely large skinfolds, the thumb and finger will need to be separated more than 8 cm in order to lift the fold. Keep the fold elevated while the measurement is taken.

Place the jaws of the caliper perpendicular to the fold, approximately 1 cm below the thumb and index finger, and release the jaw pressure slowly.

Take the SKF measurement 4 seconds after the pressure is released. Open the jaws of the caliper to remove it from the site. Close the jaws slowly to prevent damage or loss of calibration. Take a minimum of two measurements at each site.

Take SKF measurements in a rotational order rather than consecutive readings at each site. If you want a more accurate assessment and are willing to pay for it, you could pursue a method with good accuracy like hydrostatic weighing, ADP or DXA.

Ideally, you should do the test before you have anything to drink, especially for methods that rely on electrical signals like BIA, BIS and EIM. Assessing yourself the same way each time will reduce error rates and make it easier to tell if you are making progress.

However, you should always interpret your results from any method with caution. Even the best methods are not perfect and only give you an estimate of your true body fat.
