All children will be weighed using infant weighing scales or hanging scales that are usually used for weighing children during child welfare clinics for children unable to stand alone and a mechanical stand-on scale for older children who can stand alone. Supine length of children will be recorded using a measuring board whilst a height measure will be used to take the standing height of all children 2 years and above. The mid upper arm circumference (MUAC) of each child will be measured with a MUAC tape (TALC Institute of Child Health).
