Abstract

MARISCAL-ARCAS, M. et al. Comparison of methods to evaluate the quality of the Mediterranean diet in a large representative sample of young people in Southern Spain. Nutr. Hosp. [online]. 2010, vol.25, n.6, pp.1006-1013. ISSN 1699-5198.

The objective of this study was to compare the usefulness of two methods to evaluate diet quality in young people in Southern Spain: a new Mediterranean Diet Pattern (MDP) and a modification of the Diet Quality Index-International (DQI-I) for the Mediterranean area. The study population was 3190 schoolchildren aged 8-15 yrs. The questionnaires used were first validated (Bland-Altman plot and Wilcoxon tests) in a randomized sample. The DQI gives a more detailed evaluation of food components, whereas the MDS gives global information on food groups but includes foods characteristically consumed in the Mediterranean region. Highly similar results were obtained using the MDP and the adapted DQI-I, which appear to be equally useful to evaluate diet quality in a Mediterranean population. The fact that we selected the same types of food for both indices may explain the similar overall evaluations. According to these results, both methods appear to be equally appropriate for evaluating diet quality in a Mediterranean population.
