The Probability Distribution Framework for estimating the Prevalence of Undernourishment
Food security working paper

2007

In his pioneering study carried in the early 1960’s, Sukhatme had formulated the estimate of the prevalence of undernourishment in a population within a bivariate distribution framework where dietary energy consumption (DEC) and dietary energy requirement (DER) are considered as random variables.  

The effect of sampling design on the reliability of estimates of the variance of distributions derived from household survey data: a simulation study
Statistics working paper series

2007

On a regular basis, FAO produces estimates of the prevalence of undernourishment and related measures that require estimates of the frequency distribution of household per capita food consumption, expressed in terms of dietary energy (kilocalories).

A non-parametric approach suggested by researchers from the International Food Policy Research Institute (IFPRI) for measuring food deprivation (undernourishment) is not an improvement to the current FAO parametric approach.

A non-parametric approach suggested by researchers from the International Food Policy Research Institute (IFPRI) for measuring food deprivation (undernourishment) is not an improvement to the current FAO parametric approach.    

Estimating household and institutional food wastage and losses in the context of measuring food deprivation and food excess in the total population
Food security working paper

2006

The FAO’s measure of food deprivation, the prevalence of undernourishment, is conceptually based on a comparison of dietary energy intake (DEI) with a normed minimum energy requirement which is compatible with a healthy life while performing light physical activity, taking into account the inequality in access to food.
