What is anthropometry?

Branch of anthropology

Involves the quantitative measurement of the human body.

Single most portable, universally applicable, inexpensive and non-invasive technique for assessing the size, proportions and composition of the human body.

MUAC related techniques

• Quac stick (Quaker arm circumference measuring stick)

• Measures both MUAC and height

• Detection of acute malnutrition

17

Skin fold thickness

• Over the triceps or subscapular region• Harpenden’s calipers

Indices• Rao and Singh weight-height index

Normally more than 0.15

• Kanawati and McLaren MUAC-HC index

Normally more than 0.31

• Ponderal index

less than 2 = asymmetrical IUGRmore than 2 = symmetrical IUGR, normal babies

Assessment of normal growthWeight Height

Birth 3kg Birth 50 cm

Doubles 5 m 3 m 60 cm (3cm/m)

Triples 1 yr 1 yr 75 cm (1.7cm/m)

Four times 2 yr 2 yr 87.5 cm (1cm/m)

Five times 3 yr 3 yr 95 cm (7.5cm)

Six times 5 yr 4 yr 100 cm

Seven times 7 yr 5 yr 106 cm

Birth 34 cm Birth 31 cm

3 m 40 cm (2cm/m) 9 m - 1 yr 46 cm

6 m 43 cm (1cm/m)

1 yr 46 cm (0.5cm/m)

2 yr 48 cm

3 yr 49 cm

4 yr 50 cm18-10-2013

Things to remember

• Anthropometric assessment should always be done in children less than 5 years

• Assessment should be done 6 monthly till the age of 5 years, and then yearly in children between 6-18 years

• Weight, height and head circumference are important anthropometric measurements in under-5 children
