Reproducibility of a food frequency questionnaire used in the New York University Women's Health Study

Article Abstract:

Volunteer participants in substudies regarding reproducibility of dietary questionnaire measurements are more likely to provide accurate responses to the questionnaire. The research, conducted among enrollees to New York University Women's Study, revealed that the phenomenon is more inclined to accuracy of reporting of absolute intake levels rather than the dietary composition. Self-selection was likewise responsible for the difference in food consumption habits.
