The objective of this study was to compare nutrient intake of two 24-hour recalls collected using the Automated Self-Administered 24-Hour Dietary Recall to a 4-day food record. A convenience sample of university-affiliated adults was chosen because of the diverse population at this university. Ninety-three participants completed the 4-day record and were then prompted to complete two 24-hour recalls within 2 weeks after. Pearson correlation coefficients were calculated for nutrient intake and Healthy Eating Index 2005 (HEI-2005), a summary measure of diet quality. Nutrients and HEI-2005 were also divided into quartiles and percent agreement and kappa values were calculated. Results' indicated that mean nutrient intakes were similar across the recall and record. Pearson correlations comparing the record and recall ranged from 0.16 to 0.78; with most correlations being between 0.4 and 0.6. For quartiles of dietary intake, percent agreement was moderately high (62.6% to 79.8%), with low to moderate kappa values (kappa=0.11 to 0.52). The 24-hour recall provided a good overall ranking of intake compared to a 4-day food record. Overall correlations and percent agreement were moderate across the nutrients and HEI-2005, suggesting that the 24-recalls may have been capturing different information than the food record in our population. Individual researchers will need to weigh the benefits of a more automated system, such as efficiency, against the potential loss of food item detail and potential need for larger sample sizes, for their particular study populations.
