Summary
Comparing the 24-hour dietary recall (DR) and consumption tendency interview (CTI) for food consumption and nutrient intake assessment, this study found both methods yield similar population-level results. Method suitability depends on specific research objectives.
Area of Science:
- Nutrition Science
- Dietary Assessment Methods
- Public Health Nutrition
Background:
- Accurate dietary assessment is crucial for understanding population health and nutritional status.
- The 24-hour dietary recall (DR) and consumption tendency interview (CTI) are common methods for collecting food consumption data.
- Evaluating the comparability of different dietary assessment tools is essential for reliable research.
Purpose of the Study:
- To compare food consumption and nutrient intakes derived from a 24-hour dietary recall (DR) and a consumption tendency interview (CTI).
- To assess the agreement between DR and CTI at both individual and population levels.
- To determine the suitability of DR and CTI for different research objectives in nutritional studies.
Main Methods:
- Simultaneous application of 24-hour dietary recall (DR) and consumption tendency interview (CTI) to 264 schoolchildren and 272 adults.
- Collection of demographic, anthropometric (including BMI), and dietary data.
- Statistical analysis using means, standard deviation, ANOVA, and Pearson's correlation to compare food portions and nutrient intakes.
Main Results:
- No significant differences were observed between DR and CTI for cereals, fruits, meats, and sugars consumption.
- CTI reported significantly higher consumption of dairy products and oils (p < 0.01).
- Nutrient intake comparisons showed no significant differences for beta-carotene, vitamins A, C, iron, and zinc; however, omega-3 fatty acid, cholesterol, vitamin E, and folate showed notable differences (>10% of total intake).
- Correlation coefficients between methods were generally low (< 0.4), slightly higher for adults regarding cereals, dairy, and sugar (approx. 0.5).
Conclusions:
- Both 24-hour dietary recall (DR) and consumption tendency interview (CTI) provide comparable results at the population level for many food groups and nutrients.
- Significant differences in dairy and oil consumption, along with certain nutrients, highlight potential method-specific biases.
- The choice between DR and CTI should be guided by the specific research aims and the level of detail required for individual versus population-level analysis.
