2.3.2. Anthropometry

Anthropometric measurements of every child (weight, height, MUAC and head circumference) were collected as per standard WHO protocols [17]. Children were weighed with an electronic infant scale or an electronic adult weighing scale with reading increments of 10 g. Height or length was taken using an infantometer, recorded to the nearest 1 mm, and head circumference was also measured (using non-stretchable plastic tapes, recorded to the nearest 1 mm). Mid-upper arm circumference was obtained using a standard tape measure to the nearest 1 mm. These measures were used to create a height-for-age *z*-score (HAZ), weight-for-age *z*-score (WAZ) and a weight-for-height *z*-score (WHZ) for each child.
