Resumen
REYES SUAREZ, Óscar Adrián; GARCIA PEREA, María Dolores y BEJAR PRADO, Luis María. Evaluation of dietary intake using the e-EPIDEMIOLOGY app: comparison with a food frequency questionnaire in a sample of workers. Rev Asoc Esp Espec Med Trab [online]. 2017, vol.26, n.4, pp.228-237. Epub 12-Feb-2024. ISSN 3020-1160.
Background:
New technologies open up new possibilities for improving conventional methods for determining dietary intake.
Objectives:
To compare the usual intake data obtained with a mobile phone application (e-EPIDEMIOLOGY) with those collected using a previously validated Food Consumption Frequency Questionnaire (CFCA).
Material and methods:
Andalusian workers aged 26-68 used e-EPIDEMIOLOGY for 28 days and filled out a CFCA (paper) at the end of the study period. The degree of agreement between the categories of habitual consumption for the foods/drinks studied was evaluated using Spearman’s correlation coefficient (SCC), cross-classification analysis and weighted kappa index (K).
Results:
68 participants completed the study. SCC showed high association (0.63). Cross-classification analysis showed that 87.8% of the subjects were correctly classified (same category or adjacent category). K indicated an acceptable concordance (0.46).
Discussion: The results indicate that e-EPIDEMIOLOGY has a good agreement with the CFCA.
