The household selection for anthropometry across DHS surveys is quite standardized. In most of the cases, the households selected for anthropometry is a sub-sample consisting of one half or one third of the households selected for the women survey, depending on the sample size and fertility level. In a few countries with low fertility rate, or in some special cases for the purpose of a specific indicator related to children under five, anthropometry is conducted in all households selected for the women survey. In case of sub-sample selection of households for anthropometry, the selection procedure is systematic. In all cases, DHS never select children within household for anthropometry; it is always applied to all children under five found in the selected household. This is for survey efficiency considerations. All Uganda DHS surveys followed the standard procedure for anthropometry. Hope this is helpful.
