CDC recommends that nutrition survey reports on acute malnutrition should, for the immediate future, use both the WHO/CDC/NCHS reference and the WHO standards. Considering the programmatic importance of comparing year-to-year data, if prevalences based only on the WHO growth standards were reported, they could not be compared easily with levels reported from previous years based on WHO/CDC/NCHS reference. For example, reporting a SAM level of 4.4% using the WHO standard, without explaining that it corresponds to a SAM level of 1.8% based on the WHO/CDC/NCHS reference, might be somewhat misleading. The guidelines that designate levels of GAM and SAM at which large-scale nutritional interventions are indicated should be updated to reflect expected changes in magnitude of acute malnutrition observed with the new standards. Finally, more research might be needed to determine what Z-score cutoffs are appropriate for classifying individual children as having moderate or severe acute malnutrition. The focus should be on determining cutoffs that are most sensitive and specific for malnutrition-related morbidity and mortality. If the currently recommended WHO Z-score cutoffs for admission into feeding programs are applied, both the funding and the size of the feeding programs (accounting for the number of trained staff required, infrastructure, and feeding commodities) will have to increase several-fold. If the agencies are not prepared to immediately substantially increase their feeding program funding and operations in parallel with a substantial increase in the number of children eligible for admission into feeding programs, the quality of care might be compromised and resources diluted.
