  1. Inter- and intra-individual variability in food intake of elderly people in Perugia (Italy).

    Article - En anglais

    It has been shown that each individual has a considerable day-to-day variation (intra-individual variation) in his or her level of food consumption.

    A large intra-individual variation has adverse effects on the reliability of research studies.

    The erect of the intra-individual variation can be minimized by taking food intake records over several days.

    An increase in the number of days entails higher costs, and this could limit the practicability of the study.

    In the recent literature on the methodology of dietary surveys, there is a growing interest in the estimation of the number of days required to conduct a reliable dietary survey.
