Printed in US4 A Short Dietary Method for Epidemiologic Studies II. Variability of Measured Nutrient Intakes1’2’3

mating individual usual intakes were available for field studies, dietary hypothe-ses could be tested with ease and accuracy in epidemiologic investigations. Our ob-jective was to develop a standard question-naire containing a limited number of food items that 1) could be completed by each study participant in a short time pe-nod and 2) could estimate individual nu-trient intakes with accuracy and reproduci-bility. Although individual day-to-day variations could limit the accuracy of a short dietary method, knowledge of these variations should increase the potential of developing a reproducible method. There-fore, we investigated the variability of nutrient intakes of a sample of Japanese-American men before deriving a short From the School of Public Health and Depart
