Question

The measure of number of different food groups consumed over a specific reference period (24 hr/ 8hr/ 7 days) is known as ..............

• A. Household food insecurity scale
• B. Household dietary diversity scale
• C. Household hunger scale
• D. Coping strategies index

Hint:

Nutritional Scale Keywords:
- Count of food groups consumed $\rightarrow$ Household Dietary Diversity Scale (HDDS).
- Severe deprivation/starvation experiences $\rightarrow$ Household Hunger Scale (HHS).
- Behavioral responses to crisis $\rightarrow$ Coping Strategies Index (CSI).

Answer 1

The Correct Option is B

Concept:
Dietary assessment indices are qualitative recall metrics designed by international nutritional agencies to evaluate food access, nutrient adequacy, and household-level food security.
Nutritional quality correlates directly with dietary variety across essential food categories.

Step 1: Defining Dietary Diversity Metrics:
The Household Dietary Diversity Scale (HDDS), standardized by the Food and Agriculture Organization (FAO) and USAID, is a qualitative count metric.
It calculates the total number of distinct nutritional food groups consumed by household members over a specified recall reference window, typically the previous 24 hours, 8 hours, or 7 days.
Standard standardized food groups include cereals, root tubers, vegetables, fruits, meat, eggs, fish, legumes, dairy products, oils/fats, and sugars.

Step 2: Analysis of Alternative Nutritional Indices:
1. Household Food Insecurity Access Scale (HFIAS): Measures the degree of anxiety, perceived insufficiency, and behavioral alterations caused by food deprivation.
2. Household Hunger Scale (HHS): A specialized subset of food insecurity metrics focusing solely on severe deprivation (e.g., going entire days without eating).
3. Coping Strategies Index (CSI): Measures adaptive household behaviors (such as borrowing food, rationing meals, or consuming seed stock) during acute economic stress.

Step 3: Verification of the Indicator:
Because the definition provided in the question specifically refers to counting the variety of food groups consumed across a designated reference recall period, it directly matches HDDS.
Final Answer:
The measure of different food groups consumed is the Household dietary diversity scale, corresponding to option (B).
