Dietary recall method comparison for hospitalized elderly subjects

Area of Science:

• Gerontology
• Nutritional Science
• Public Health

Background:

• Accurate dietary assessment is crucial for elderly health.
• Traditional methods like oral recall may have limitations in this population.
• Evaluating alternative methods is essential for improving nutritional monitoring.

Purpose of the Study:

• To compare the accuracy of three 24-hour dietary recall methods in elderly individuals.
• To assess recall of both food item quantity and consumption amounts.
• To identify the most effective method for this demographic.

Main Methods:

• A comparative study involving 60 hospitalized elderly patients (aged 65-94).
• Three recall methods were tested: unaided oral recall, printed questionnaire, and interview with visual aids (color pictures).
• Data analyzed for accuracy in number of items and food amounts recalled, considering demographic factors.

Main Results:

• No significant overall difference in accuracy was found between the three methods.
• However, participants older than 76 (above the median age) showed higher accuracy with the printed questionnaire.
• Demographic factors like sex, education, obesity, residence, and food preparer did not significantly impact recall scores.

Conclusions:

• The printed questionnaire may offer a slight advantage for older elderly individuals in dietary recall accuracy.
• Further research could explore tailored dietary assessment tools for specific elderly subgroups.
• Standard dietary recall methods appear generally comparable across diverse elderly populations.
