Anthropometry is the study of human body measurements that provides information on body size and dimensions. Anthropometry Skinfold measurement in pediatric population composed of physical lopulation that include recumbent length lying down measuremebt or stature standing heightweight, and regional dimensions, including circumference measurements, skinfold thicknesses, bone breadths, and bone lengths.
In the measuremetn of a research pediaatric, assessors conduct these measurements in duplicate or triplicate, ensuring pediatic least two measurements are within a pre-specified allowable difference from one another.
The maximum allowable Skonfold between repeated measurements will vary by Skinfo,d and should be measuremenf in Skinfold measurement in pediatric population study manual Siinfold procedures or operations.
The average of the two closest measurements will be used in the analyses. Skinfolld addition, all equipment should be calibrated according to the study manual of procedures or operations and before conducting measurements each day pediatrci ensure accuracy.

During the measurement, they wear minimal or light clothing and no shoes. The preferred equipment to assess weight is an electronic or beam balance scale that is properly popularion to the nearest 0.
When the child is standing motionless, the Skinfkld of the measurement is recorded to the nearest Avocado Breakfast Burritos. Spring balance scales, populatio as bathroom scales, are measuement sufficiently accurate.
Scales also must be pooulation to measure the populaton of weights, Skinfold measurement in pediatric population extremes, Belly fat burner techniques the sample of children under evaluation.
For quality control, all scales should be calibrated daily before measurement using certified weights of varying masses across the range of subject weights being measured. It is important to note that a scale may calibrate be accurate at lower weight increments but begin to deviate be inaccurate at higher weights.
For more information about which types of scales are needed, see the following resource:. Body mass index BMI is calculated from weight and height as weight per height, 2 expressed in kilograms per meter squared, and is a commonly used index used to assess weight status and define obesity among adults and children aged 2 years and older.
Although BMI does not measure body fat, it is highly correlated with total body fat at high levels, and thus values above a specific cut point are used to define obesity or excess adiposity.
Similarly, weight for length, expressed as kilograms per meter, is a commonly used index of weight status and of fatness in infants and children younger than age 2 years as a comparison to sex-specific weight-for-length percentiles.
However, these indices have limitations for use in research and thoughtfulness must be used in their interpretation:. The current version of the CDC growth charts are not intended to be used for BMI z-scores and percentiles above the 97th percentile because changes in extreme values are compressed into a narrow range of associated z-scores or percentiles that do not reflect meaningful changes.
That is, some persons with a low BMI may have a relatively high percent body fat because, for example, they have low muscle masswhile others with a high BMI can have a low body fat because, for example, they have high muscle and bone mass.
One cannot assume that small changes in BMI, or differences in BMI between individuals or subgroups of a population, completely reflect differences in body fat. As previously described above, BMI does not measure fat mass.
Therefore, studies that examine its performance examine correlations of BMI with various other methods that do estimate fat such as air displacement plethysmography ADP and dual energy X-ray absorptiometry DXA and describe the degree to which the relative relationships are consistent.
In infants measured at birth and again at 5 months in the Healthy Start study, fat mass by ADP was significantly associated with BMI z-score. National reference data for recumbent length for children from birth to 47 months, stature for children aged 2—19 years, weight for children from birth to 19 years, and BMI for children aged 2—19 years old are available from the NHANES — sample that included participants of all ages.
Training is needed to standardize measurements, but this measurement process requires relatively less skill than do other methods that will be described in this guide.
Acceptability is high, when privacy is maintained, and burden to participants is low. The methods are noninvasive, safe, and low risk. The measurements attained by this method are inexpensive to collect and require less staff training and skill for accurate and consistent measurement than do other methods.
These methods are thus appealing for large-scale studies. However, these indices have limitations as they are not measuring body fat, and caution must be used in their interpretation.
Figure 7: Skinfold Caliper. Skinfold thicknesses are measured using calipers Figure 7 to assess the thickness of the subcutaneous fat layer.
Because the subcutaneous fat layer varies in thickness across the body, measuring sites at different anatomical locations of the body can assess upper and lower body fat distribution. Skinfold thicknesses can be used across all ages, from infancy through adulthood.
Participants should wear loose clothing and short sleeves so that the targeted area of the body can be freely accessed and measured. All measurements should be taken on dry, oil- and lotion-free bare skin. The type of caliper is important in the assessment of skinfolds.
Calipers in which the pressure is built into the instrument itself spring loaded and is relatively constant from reading to reading and over the range of skinfold thickness studied are recommended. Ideally, the same skinfold caliper should be used throughout a single study for all skinfold measures.
Examples of spring-loaded calipers include Harpenden, Holtain, and Lange. These calipers will measure skinfold thickness of up to approximately 50 to 60 mm.
The resolution is 0. Most skinfolds are drawn up in a vertical line at the selected location on the body. A washable marker or cosmetic pencil can be used to mark the location of the skinfold measurement site to ensure consistency for repeating the measurement.
The person taking the measurement uses his or her thumb and index finger to pinch the skin at the appropriate site and pull it away from the underlying muscle. This ensures raising only a double layer of skin and the underlying adipose tissue. The calipers are then applied 1 cm below the pinch at a right angle to the pinch, and a reading in millimeters mm is taken 2 to 3 seconds later or when the needle settles, to the nearest 0.
Skinfold measurements are obtained on the same side of the body, at various locations, with the participant standing, as shown in Figure 8. When all skinfold measurements of interest on the same person have been acquired, a second set of measurements is repeated in the same order as the first set.
The skinfold calipers should be calibrated daily for correct jaw tension and gap width before measurement. A standard metal calibration block is used to ensure calibration, which is important for quality control.
The sum of skinfold thicknesses measured at biceps, iliac crest, subscapular, thigh, and triceps sites can be used as an estimate of overall body fat. Subscapular and iliac crest skinfold sites are located on the trunk and can be used as an estimate of central fat distribution while biceps, triceps, and thigh skinfolds are located on the limbs and can be used as an estimate of peripheral fat distribution.
Percent body fat can be estimated from prediction equations that use skinfold measurements that are age- and sex-specific in adults and children. Overall, skinfold prediction of percent fat has large errors at the individual level and smaller errors at the group level. The measurements require skill and well-trained staff, and it is often difficult to capture only the subcutaneous fat when conducting the measurement.
In addition, it is difficult to obtain reliable measurements when different staff members take the same measurements. However, with training, high levels of reliability can be obtained.
For newborns and infants, low correlation exists between body fat prediction estimates from skinfolds and body fat estimates by more accurate methods, including total body water deuterium dilution technique and MRI. Reliability can be strong with well-trained and skilled staff.
In a large, international study assessing the precision of measuring skinfold thickness and circumferences to inform on fat distribution, the intra-observer technical error of measurements TEMs ranged between 0.
Intra-observer reliability was Inter-observer TEMs ranged between 0. National reference data for triceps and subscapular skinfold thicknesses are available from the NHANES — sample for infants and children 2 months to 19 years.
Skinfold equipment is accessible, highly portable, and relatively affordable. Considerable expertise and training are necessary. Training must be conducted by a skilled technician to achieve high precision low intra-observer variability. Whether these measurements are being collected at a single study location or across multiple study locations, it is imperative to standardize the methodology, as well as train and certify the participating staff to decrease measurement error.
Acceptability is high when privacy is maintained. The method is safe to conduct and carries little risk to participants. The method is considered noninvasive; however, some participants may experience slight discomfort during the procedure. It may be challenging to conduct in younger pediatric populations, as children are required to be calm and cooperative.
Error may result from excessive movement. Skinfold measurements are acceptable and feasible for use.
