Low accuracy and low consistency of fourth-graders' school breakfast and school lunch recalls

Area of Science:

• Nutritional Sciences
• Pediatric Nutrition
• Dietary Assessment

Background:

• Accurate dietary intake assessment is crucial for understanding children's nutritional status and the effectiveness of school meal programs.
• Existing methods like 24-hour dietary recalls have limitations in accurately capturing children's food consumption.
• The accuracy and consistency of dietary recalls in young children remain a significant concern for researchers and public health professionals.

Purpose of the Study:

• To evaluate the accuracy and consistency of fourth-graders' self-reported school breakfast and school lunch intake.
• To compare children's recalled food consumption with directly observed intake.
• To identify potential biases and inaccuracies in children's dietary recall methods.

Main Methods:

• A multiple-pass recall protocol was used to interview 104 fourth-grade children stratified by ethnicity and gender.
• Children were interviewed at school shortly after their school meals were observed.
• Dietary recalls were administered up to three times per child over a 4- to 14-week period to assess consistency.

Main Results:

• High omission rates (51%) and intrusion rates (39%) were observed, indicating significant inaccuracies in reporting.
• Total inaccuracy in reporting food items and amounts decreased significantly from the first to the third recall.
• Intraclass correlation coefficients (ICC) for total inaccuracy (0.29) and omission rate (0.15) indicated low consistency in reporting.

Conclusions:

• The study findings raise concerns about the reliability of current 24-hour dietary recall methods for assessing children's food intake.
• Low accuracy and consistency in children's dietary recalls highlight the need for improved data collection techniques.
• Further validation studies are essential to develop and refine methods for obtaining more accurate dietary information from children.
