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


METHODS
Cross-sectional study design.


METHODS
Urban university-based family practice.


METHODS
The 105 subjects included outpatients, medical students, and staff.


METHODS
Correlation between the DRA and Keys score.


METHODS
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
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.
