- W4304758043 abstract "Information on food consumption, dietary diversity, and nutrient inadequacies are key for informing food security and nutrition programming. Household- and individual-level data together provide the most complete information, but individual dietary modules are not always feasible in humanitarian contexts due to cost and time constraints.This article asks to what extent it is possible to use food consumption data which is commonly collected at household level through food security and vulnerability surveys, to assess the household's access to vitamin A and iron.The validation analysis uses household food consumption and expenditure surveys from Guatemala, Honduras, Nepal, and Uganda and the adult male equivalent approach for calculating nutrient access.The results show a positive significant correlation between the frequency of consumption and adequacy as estimated from comprehensive household food consumption modules, with correlation in the range of 0.4 to 0.7. Frequency thresholds for distinguishing between adequate and inadequate nutrient access, based on how often foods rich in the relevant nutrient are eaten during 1 week, mostly fulfill standard sensitivity and specificity criteria.The article concludes that in humanitarian contexts, a frequency-based proxy for nutrient access based on household data commonly collected in emergency assessments and through monitoring systems can be used and can support this particular data gap. As a rule of thumb, a frequency threshold of 7 should be used for vitamin A and of 12 for iron." @default.
