Question

Which of the following is a qualitative dietary assessment method used at family or individual level?

• A. Food record
• B. 24 hour recall
• C. Diet history
• D. Food frequency questionnaire

Hint:

FFQs do not measure exact portion weights, which makes them qualitative.
In contrast, 24-hour recalls and food records track precise portion sizes, making them quantitative.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Dietary assessment methods are used to evaluate food and nutrient intake.
These methods are classified as quantitative (measuring exact amounts of foods consumed) or qualitative (assessing food habits and frequency of consumption).

Step 2: Detailed Explanation:
- Quantitative methods (such as the 24-hour recall, food records, and weighted food diaries) collect detailed data on portion sizes to calculate exact nutrient intakes.
- Qualitative methods focus on the patterns, habits, and frequency of food consumption rather than precise portion weights.
- The Food Frequency Questionnaire (FFQ) is a qualitative or semi-quantitative tool.
It uses a structured list of foods and asks respondents how often they consume them (e.g., daily, weekly, monthly, or never).
While some versions include portion estimates (semi-quantitative), the primary purpose of an FFQ is to qualitatively assess long-term dietary habits and patterns.
This makes it highly valuable for epidemiological studies linking diet to chronic disease.
Therefore, the Food Frequency Questionnaire is categorized as a qualitative dietary assessment method.

Step 3: Final Answer:
The Food Frequency Questionnaire is a qualitative dietary assessment method used to evaluate long-term dietary patterns.
