Anthropometry
The measurement of body size, weight, & proportions.
Frankfort horizontal plane
Represented by a line between the lowest point on the margin of the orbit & the tragion.
Recumbent length
Generally used for children 0 to 24 months, child is supine. Head must be in Frankfort horizontal plane.
Stature
Standing height
stadiometer
Subject should be barefoot, facing forward, feet against wall, heels together, head in Frankfort plane, body in contact with stadiometer.
parallax
A difference in the apparent reading of a measurement scale when viewed from various points not in a straight line with the eye.
Head circumference
The lower edge of the tape should be positioned just above the eyebrows, above the ears, and around back of head over the occiput.
Infant weight is recorded to the nearest ?
10g, children and adults to nearest 100g
Growth Reference
A chart based on anthropometric measures performed on a large group of infants & children in a particular place & time. Describes what is, or exists, not what is ideal.
Growth Standard
Chart created using anthropometric data collected from a large group of infants & children who are growing under optimal conditions. Describes what should be.
Overweight
A body weight greater than some reference point that is usually defined in relation to height.
Obesity
An excess amount of body fat in relation to lean body mass.
Hamwi equations
Men: 106lb. for first 5ft + 6lb. for each in over 5ft ± 10%. Women: 100lb. for first 5ft. + 5lb. for each in. over 5ft ± 10%.
Measuring elbow breadth
Subject stands erectly, right upper arm extended forward perpendicular to the body. Forearm is flexed to 90º angle, palm facing subject.
Formula for determining frame size
r=H/C. Where r is the ratio of ht to wrist circumference. H & C in cm
relative weight
A person’s actual weight / some reference weight x 100
Quetelet’s indes
W/H^2. aka. body mass index
nomogram
A graphic device with several vertical scales allowing calculation of certain values when a straightedge is connected between two scales and the desired value is read from a 3rd scale.
Waist-to-Hip ratio
(WHR). Calculated by dividing the waist circumference by the hip (or gluteal) circumference. <0.8 for females.
How to measure waist circumference
Locate top of right iliac crest, place measuring tape in horizontal plane around abdomen at the level of the iliac crest.
“high risk” waist circumference
> 40 in (102cm) in males. >35 in (88cm) in females. Also useful in evaluating success of weight loss, not applicable to those <60 in.
Two-compartment model
Body is divided into 2 compartments. Fat mass & fat free mass.
Four compartment model
Body is composed of 4 chemical groups: water, protein, mineral, fat.
