||Guidelines for measuring household and individual dietary diversity
||Obtaining detailed data on household food access or individual dietary intake can
be time consuming and expensive, and requires a high level of technical skill both
in data collection and analysis. Dietary diversity is a qualitative measure of food
consumption that reflects household access to a variety of foods, and is also a proxy
for nutrient adequacy of the diet of individuals. The dietary diversity questionnaire
represents a rapid, user-friendly and easily administered low-cost assessment tool.
Scoring and analysis of the information collected with the questionnaire is
straightforward. The dietary diversity scores described in these guidelines consist
of a simple count of food groups that a household or an individual has consumed
over the preceding 24 hours. The guidelines describe the use of the dietary diversity
questionnaire at both the household and individual level, for which calculation of
the score is slightly different in each case. The data collected can also be analyzed to
provide information on specific food groups of interest.
The household dietary diversity score (HDDS) is meant to reflect, in a snapshot
form, the economic ability of a household to access a variety of foods. Studies
have shown that an increase in dietary diversity is associated with socio-economic
status and household food security (household energy availability) (Hoddinot and
Yohannes, 2002; Hatloy et al., 2000).
