Nutritional assessment is the process of estimating the nutritional status of an individual or group at a given point in time by using different assessment method. Its purpose is to determine the nutritional status of an individual or a community and helps to monitor trends in the change of nutritional status over time. It also helps to monitor the effectiveness of nutritional intervention so as to consider options accordingly. There are four different methods to collect nutritional information:

a. Anthropometric measurement
b. Clinical assessment
c. Biochemical assessment
d. Dietary assessment


Anthropometric measurement

This is the measurement of the various physical dimensions and the gross compositions of the individual body at different age levels and status of nutrition. Anthropometric assessment is done for two purposes, i.e. measurements of growth, and body composition.

Length

Length is measured by using a wooden measuring board (also called sliding board). It is used for measuring the length of children less than two years old to the nearest millimetre. Measuring the child lying down always gives readings greater than the child‘s actual height by 1-2 cm.

Procedure:

Figure 3.1: - Measuring length, (source UNICEF1986, how to weigh and measure children: assessing the nutritional status of young children).

Height

This measurement is taken in a standing position for children who are 2 or more years old and for adults. The position of the client should be Frankfurt (where the line passing through the external ear hole to the lower eyelid and parallel to the floor) during measurement, the client's shoulders, buttocks and the heels should touch the vertical stand. Either a stadiometer or a portable anthropometry can be used for measuring. Measurements are recorded to the nearest millimetre.

Weight

The weight of children under two years old is measured by spring balance or Salter Scale, for adults and children over two years old a beam balance is used. The measurement is also to the nearest 0.1 kg for both measurements.
