The relationship between food insecurity and dietary outcomes. An analysis conducted with nationally representative data from Kenya, Mexico, Samoa and the Sudan

02/08/2021

Little research has been conducted on the association of food insecurity, particularly at the moderate level, and dietary consumption in low- and middle-income countries. This study expands on previous works by considering cross-country comparable measures of food insecurity that are calibrated against the global Food Insecurity Experience Scale (FIES). The FAO Statistics Division has been publishing estimates of the prevalence of food insecurity, based on the FIES, since 2017.

Producing, reporting, and interpreting vitamin A statistics present multiple challenges largely attributable to the systems of equivalence used to convert pro-vitamin A carotenoids into retinol equivalents, and to the criteria used by institutions to set recommendations.

In many countries, statistics from household consumption and expenditure surveys are increasingly being used to inform policies and programs. In household surveys, foods are typically reported as they are acquired (the majority are raw).

Surveys focused on food acquisition collect higher food quantities compared to those that target food consumption. Surveys based on recall interviews collect higher food quantities compared to those based on diaries, but the difference decreases with long reference periods.

National food security assessment through the analysis of food consumption data from Household Consumption and Expenditure Surveys: The case of Brazil’s Pesquisa de Orçamento Familiares 2008/09, Food Policy, Volume 72, 2017

This article focuses on the use of Household Consumption and Expenditure Surveys (HCES) as a source of data to inform food security assessments. We argue that the quality and characteristics of food consumption data collected in HCES may limit the reliability of food security assessments, as parameters estimated from survey data may be biased due to systematic flaws in the collection of food data.
