Predictors of the accuracy of telephoned dietary recall data in a group of free-living elderly subjects.
As part of a study evaluating the accuracy of dietary intake data from telephoned 24-hour dietary recalls, an attempt was made to predict, on the basis of their health, social, demographic and dietary characteristics, which subjects would provide data containing the greatest error. Unexpectedly, the statistical model for the overall error score was predictive of smaller rather than larger errors. All variables it contained were reasons why an individual might have a heightened awareness of their food consumption. Work should be undertaken to determine whether this model also has predictive ability in face-to-face dietary interview settings and with non-elderly subjects.
