Identifying Non Diet Survey Methods
Diet surveys aim to collect data about an individual's or group's food consumption patterns.
Analysis of Options
- Food frequency questionnaire: Asks how often specific foods are consumed over a period. This is a common diet survey method.
- 24 hrs recall method: Involves asking individuals to list all foods and drinks consumed in the preceding 24 hours. This is a direct method for assessing dietary intake.
- Food weighment: Involves precisely measuring the weight of foods consumed. This is a detailed and accurate diet survey method.
- BMI: Body Mass Index is calculated using height and weight (BMI = weight (kg) / height (m)^2). It is an indicator of body fatness and nutritional status, but it does not directly measure or survey food intake.
Conclusion
While BMI is related to nutritional status, which is influenced by diet, it is not a technique used to survey or measure dietary intake itself. Therefore, BMI is not a method of diet survey.
