Using multiple 24-hr recalls (24HR) we tested the Seven Day Dietary Recall (7DDR) developed to assess nutrient exposures, especially lipids, in dietary interventions and other clinical trials requiring measurement of effect over moderate time periods.
A total of 261 individuals in three studies completed a 7DDR at the end of a 3-to 5-week period during which 3 to 7 24HR were telephone-administered on randomly selected days.
One of these studies and data from one additional study (total n=678) allowed us to test the ability of the 7DDR to predict serum lipid changes in an intervention setting.
In correlation and linear regression analyses, high levels of agreement between 7DDR and 24HR were obtained.
For total energy : r=0.67 and b=0.69, and for total fat intake (g/day) : r=0.67 and b=0.80.
When 7 days of 24HR were available agreement tended to he higher.
For total energy : r=0.69 and b=0.95, and for total fat (g/day) : r=0.71 and b=1.04.
Data derived from the 7DDR and fit to the Keys and Hegsted equations closely predicted actual changes in total serum cholesterol (within 15% and 10%, respectively).
The 7DDR is a relatively easily administered, sensitive method to assess short-term changes in dietary fat consumption in individuals.
