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. In a similar way to body mass index BMI , they can be converted into standard deviation scores SDS for longitudinal evaluations. The triceps site is the most commonly used single-site skinfold measurement as it is easy to measure and reference data e.

WHO triceps skinfold thickness for age are available for comparison. However, no equations are available for estimating body fat from a single-site skinfold measurement. Triceps measurement is also used to derive indices of body composition using arm anthropometry.

To convert raw skinfold thickness values into a percent of body fat, population-specific or generalised equations are used. These equations are 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.

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 model , see 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 residuals , and 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.

The FFI estimates body fat and muscle mass by sending electrical currents to the body and measuring the response. Muscle and fat respond differently to electrical currents, and the scale uses these differences to determine body fat. Even though this method is one of the simplest ways to estimate body fat in a home setting, there are some drawbacks to using smart scales.

A study compared the accuracy of three smart scales in measuring body weight and composition in underweight, normal weight, and overweight adults against DEXA. The researchers found that although body weight was accurately measured by the scales, body fat was underestimated One of the issues with smart scales is that their accuracy depends on the body composition of the population used to train the smart scale during production.

Plus, accuracy can vary widely between smart scale models Smart scales use a foot-to-foot impedance meter FFI to measure body composition. They can be used as an at-home method for body fat measurement, but their accuracy varies significantly.

Measuring your waist circumference can give you an idea of your body fat levels and whether or not you have a high amount of body fat stored around your midsection Carrying high amounts of fat in your midsection can significantly increase your risk of developing a number of health conditions, including heart disease, diabetes, and more Knowing your waist circumference can help you determine if you have too much fat stored around your midsection.

All you need to do is to place a non-stretch tape measure around your midsection above your hip bones, making sure the tape measure is horizontal around your waist. Keep the tape measure snug, but make sure to avoid compressing the skin In order to reduce the risk of many health conditions, health organizations recommend that waist circumference be kept below a certain measurement For example, those of Asian descent have lower waist circumference cut off values compared to those of European descent Waist circumference measurement is an easy way to assess body fat levels in your midsection.

However, these methods are typically much less reliable compared to methods used in clinical settings like DEXA. If you have questions about your body composition, including healthy body fat levels for your age, sex, and ethnicity, reach out to a trusted healthcare professional for advice.
