Anthropometrics (Body size and composition)



Height

Sitting and standing height is measured with the shoes off using an electronic stadiometer Length is measured in children too young to stand, or in individuals who can not stand, while the person is lying on their back.


Weight

Weight is measured with an electronic scale


Circumference

Circumference measures of any body segment are available. All circumference measures are completed using a cloth tape measure with a built-in tension gauge to standardize compression of skin and underlying tissue. Measures are performed in duplicate to improve accuracy. Waist, hip, and head circumference measures are routine. The waist circumference is measured by taking the narrowest point between the xiphoid process and the umbilicus. The hip circumference is measured at the maximal circumference just below the gluteal fold. The head circumference is measured above the eyebrows and ears and around the back of the head. Waist to hip ratio is found by dividing waist circumference by hip circumference. Waist circumference can be interpreted as a standalone measurement.


Circumference

Circumferential measurements of multiple body segments are available. They are completed using a cloth tape measure with a built-in tension gauge to standardize compression of skin and underlying tissue. Measures are performed in duplicate to improve accuracy. Waist, hip, and head circumference measures are routine.


Body Composition

Body fat measurements are taken using skin fold calipers.


Arm Span

Arm span is the distance between the tips of the fingers when the arms are stretched all the way out to the sides.


Chest wall excursion

Chest wall excursion evaluates the amount of available movement in the chest wall. Circumferential measurements are taken at the bottom of the chest and under the arms during a maximal inspiration (big breath) and during a maximal expiration (after exhaling the big breath).
