Objective: The objective of this pilot study was to validate the Dietary Risk Assessment (DRA) food frequency questionnaire against the Keys score obtained from 2 2-day dietary recalls in a sample of subjects.
Design: Cross-sectional study design.
Setting: Urban university-based family practice.
Participants: The 105 subjects included outpatients, medical students, and staff.
Main outcome measure: Correlation between the DRA and Keys score.
Analysis: Pearson correlation analysis.
Results: We found that the correlation between the DRA and Keys score derived from the dietary recalls was .62 (P < .001).
Conclusions and implications: The simplicity of the DRA and its correlation with dietary recall may make this a useful dietary analysis and nutrition education tool for both patients and physicians.
