Validation of the dietary risk assessment food frequency questionnaire against the Keys score for saturated fat and cholesterol

J Nutr Educ Behav. 2005 May-Jun;37(3):152-3. doi: 10.1016/s1499-4046(06)60270-4.


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.
