Dietary Survey Methods Analysis
Dietary surveys aim to assess food intake. Methods are broadly classified as prospective (measuring intake as it occurs) or retrospective (asking about past intake). This question focuses on identifying retrospective methods.
Method Classification
Let's classify the given methods:
- (i) Duplicate sample method: This is a prospective method. A duplicate portion of all food and beverages consumed by the subject is collected for analysis.
- (ii) 24-hour dietary recall: This is a retrospective method. It involves interviewing individuals about all food and beverages consumed in the preceding 24 hours.
- (iii) Food balance sheets: This is a retrospective method. It uses national statistics on food production, imports, exports, and non-food uses to estimate the food available for consumption at the household level over a specific period.
- (iv) Weighment method: This is a prospective method. Food items are weighed before consumption to determine the exact quantity eaten.
- (v) Diet history: This is a retrospective method. It involves detailed interviews about dietary patterns over a longer period (e.g., weeks or months) to assess usual intake.
Identifying Retrospective Methods
Based on the classification, the retrospective methods of dietary survey listed are:
- (ii) 24-hour dietary recall
- (iii) Food balance sheets
- (v) Diet history
Therefore, the correct option includes (ii), (iii), and (v).
