Summary
The USDA five-step multiple-pass method accurately assesses dietary intake in men across weight categories. This dietary recall method shows no bias related to body mass index, validating its use in diverse populations.
Area of Science:
- Nutritional Science
- Dietary Assessment Methods
- Human Nutrition Research
Background:
- Accurate dietary assessment is crucial for nutritional research and clinical practice.
- The USDA five-step multiple-pass method is a widely used 24-hour dietary recall technique.
- Understanding the accuracy of dietary recall across different body mass index (BMI) categories is important.
Purpose of the Study:
- To validate the accuracy of the USDA five-step multiple-pass method for dietary recall.
- To assess if body mass index influences the accuracy of dietary recall.
- To evaluate the recall of energy, protein, carbohydrate, and fat intake in men.
Main Methods:
- Observational validation study with a cross-sectional design.
- Forty-two men (BMI 21-39 kg/m²) participated in a controlled feeding study.
- Actual food intake was directly observed; recalled intake was assessed via telephone using the USDA method the following day.
Main Results:
- No significant differences were found between actual and recalled intakes of energy, protein, carbohydrate, and fat.
- Dietary recall accuracy was not significantly related to body mass index; obese men recalled as accurately as non-obese men.
- Energy intake was significantly correlated with estimated energy requirements, with notable interindividual variation in recall accuracy.
Conclusions:
- The USDA five-step multiple-pass method accurately assesses macronutrient and energy intake in men, irrespective of BMI, under controlled conditions.
- The method demonstrates reliability across normal weight, overweight, and obese individuals.
- Further research is needed to identify factors contributing to under- and overreporting in dietary recall.
