NUTRITIONAL ANTHROPOMETRY (PART 1)

Nutritional anthropometry

it is the measurement of variation of any dimensions and gross composition of human body at different age levels and degree

Man

anthro means

Measurement

metry means

Head circumference, recumbent length, height, knee height, weight and elbow breadth

Growth measurement

Fat skin fold thicken and Fat free mass

Body composition measurement

growth measurement and body composition measurement

Types of anthropometeric measurement

Procedure

simple, safe, non indusive techniques applicable to large sozes

Procedure

assist the identification of mild, moderate and severe state of mali

Equipment

inexpensive, portable and durable and can be made or purchased locally

Personnel

relatively unskilled personnel can perform measurement procedures

Methods

precise and accurate, provide the standard techniques are used

Secular trend

used to evaluate changes in nutritional status overtime and from one generation to the next, a phenomenon known as

Information

is generated on past long term nutritional history, which can't obtained with equal confident using other technique

Screening test

to identify individual at high risk to malnutrition can be devised

Recording, reading, restless child, inadequate instruments

all measurements

Length

used only when subject is <2 years old

Height

same with length, is use >2 years old

Weight

• room cold no privacy

• scale not calibrated zero

• remove or make allowance for clothing

Knee height

use to estimate height in persons with severe spinal curvature and who are unable to stand

90° angle

measured on the left leg which is bent at the knee at a

Supine position

the subject to measure the knee height is in the

Weight

assess body mass, summation of fat, body water and lean cell mass

Suspended scale

equipment use to measure the weight of a children

Salter Weighing

equipment use to measure the weight of a years old

Beam balance

equipment use to measure the weight of an adult

Birthweight

assess nutritional status of neonate

Birthweight

is related to maternal nutrition and socio economics status

2500 grams

cut off low birth weight babies is

Head circumference

used with other measurement to detect pathological conditions associated with macrocephalic head

Head circumference

to identy developmentally related and neurogically impaired individuals especially in the younger age

Head circumference

use to determine if child is growing normally

Head circumference

narrow, flexible and non flexible tape made of fiberglass 0.6cm wide or a fiber glass insertion

Frankfurt plane

imaginary line to measure the head properly

Gorpa orbital ridges

above eyebrow and ears

Recumbent length

wooden measuring board or infantometers or portable infant length measuring board

Recumbent length

measured in infants amd and children less than 2 years old

Height

measured in older children and adults

Height

assess linear dimensions of legs, pelvis, spine and the skull

Height

stadiometer or portable anthropometer

Microtoise (statur meter)

L shape device (head-bar) to which is attached a spring loaded called tape measure

Statue=2.02 x knee height (cm) - 0.04 x A + 64.19

estimate height from knee height in male (monogram)

Statue=1.83 x knee height - 0.24 x age in years + 84.88

estimate height from knee height in female (monogram)

% usual weight=actual weight/usual weight x 100%

weight changes formula

Elbow breadth

measure frame size which is independent of adiposity of age

Elbow breadth

flat based sliding caliper
