Hi Frank,
In the context of an emergency, an anthropometric survey only includes the basic measurements (including age, weight, length/height, gender, oedema) needed to calculate nutritional indices which are then used to derive estimates of malnutrition prevalence. MUAC is also often measured during anthropometric surveys. The target population is most often children 6-59 months of age.
In contrast, a nutritional survey includes additional data used to assess the nutritional and health status of the target population. Examples of such data may include hemoglobin concentration, vitamin A supplementation coverage, measles vaccination coverage, diarrheal diseases, and infant and young child feeding practices, among others.
