What do we really know? Metrics for food insecurity and undernutrition
چکیده انگلیسی

In this article, we critically review the three most common approaches of assessing chronic food insecurity and undernutrition: (i) the FAO indicator of undernourishment, (ii) household food consumption surveys, and (iii) childhood anthropometrics. There is a striking and worrying degree of inconsistency when one compares available estimates, which is due to methodological and empirical problems associated with all three approaches. Hence, the true extent of food insecurity and undernutrition is unknown. We discuss strengths and weaknesses of each approach and make concrete suggestions for improvement, which also requires additional research. A key component will be the planning and implementation of more comprehensive, standardized, and timely household surveys that cover food consumption and anthropometry, in addition to other socioeconomic and health variables. Such combined survey data will allow much better assessment of the problems' magnitude, as well as of trends, driving forces, and appropriate policy responses.

► Common metrics of food insecurity and undernutrition are critically reviewed. ► Particular focus on FAO approach, food consumption surveys, and anthropometrics. ► All have methodological/empirical problems; true extent of undernutrition is unknown. ► Concrete suggestions for improvement and further research are made. ► Key component is more household surveys linking food consumption and anthropometry.
