Understanding 24 Hour Dietary Recall Steps

The process of conducting a 24-hour dietary recall involves several sequential steps to accurately assess an individual's food intake and nutritional status. The correct sequence ensures reliability and validity of the data collected.

Correct Sequence for 24 Hour Dietary Recall

The steps involved in conducting a 24-hour dietary recall are sequenced as follows:

1. Preparation and validation of questionnaire (III): This initial step involves designing or selecting an appropriate questionnaire and ensuring it is validated for use in data collection.
2. Collecting information on the intake of food by respondent in previous 24 hours using standardized equipment (I): This is the core data collection phase where the respondent recalls their food and beverage consumption over the past 24 hours, often aided by tools like food models or pictures.
3. Converting cooked food into weights and measures of raw food (V): To accurately quantify nutrient intake, reported amounts of cooked foods are converted back to their raw equivalents using standard conversion factors.
4. Calculating the energy and nutrients using food composition tables (II): Once the food intake is quantified, standard food composition databases are used to calculate the total energy and nutrient content.
5. Comparing the energy and nutrient intake with RDA (IV): The final step involves comparing the calculated energy and nutrient intake against the Recommended Dietary Allowances (RDA) to evaluate nutritional adequacy.

Therefore, the correct sequence is III, I, V, II, IV.
