Anthropometry
Growth increments,the difference
between initial and follow-up
measurements,reflect recent
growth rate(growth velocity) and
are sensitive indicators of health
and development,
The trends revealed through serial
anthropometric data can be used
to track the growth of an
individual child,detect growth
abnormalities,monitor nutritional
status,and evaluate the effect of
nutritional intervention or the
treatment of disease.
Measurement of growth may
also be used as an index of the
general health and nutrition of
a population or subpopulation
of children.

a fixed measuring tape marked in millimeters with
its zero end at the edge of the headboard
Measuring board

Techniques
Recumbent length is measured for
children younger than 36 months of age
who cannot stand unassisted,
Tow people are required to measure an
infant’s length,
One person stands at the head of the table and
holds the infant’s head so the infant is looking
vertically upward,with the crown of the head
placed firmly against the headboard,
< 3 years of age
Key points,hold
firmly against the headboard
The another person straighten the infant’s
legs,holds the feet with toe pointed directly
up,move the footboard firmly against the feet,
then reads the measurement indicated by the
position of the footboard(the nearest 0.1cm).

Measurement of
Head circumference
H.C measurement is an
important screening procedure
to detect abnormalities of
heard growth,which usually
are due to nonnutritional
factors,
Head circumference should be
measured routinely in infants
and children until they are 36
months of age,
Instruments
Flexible,nonstretchable measuring
paper or plastic tape
Techniques
The circumference of the child’s
head at its largest area
The measurer positions the lower edge
of the tape just above the eye-brows,
above the ears,and around the
occipital prominence at the back of the
head, The tape should be pulled snug
to compress the hair.
Measurement of Chest circumference
Represents the development of lungs and chest
At birth,chest circumference is
slightly smaller than head
circumference,about 1-2 cm,less.
By the end of first year,chest
circumference is nearly equal to
head circumference,gradually the
chest development is quicker than
the head growth.
Instruments
Paper or plastic tape
The circumference from the nipple
to the shoulders angle.
