The HFIAS has nine questions that measure problems related to household food access including anxiety about procuring food, diet quality and diet quantity. Its classification system identifies a household's food access status by capturing the severity and frequency of experiences over the previous 30 days. Households are then classified as having:
a) adequate food access
b) a mild food access deficit
c) a moderate food access deficit
d) a severe food access deficit
The questionnaire on dietary diversity is designed to collect information on food groups consumed over the previous day and night at the level of the individual or household. The percentage of households or individuals consuming specific types of foods, such as Vitamin A-rich fruits or vegetables, can also be obtained.
