Construcción de un cuestionario de frecuencia de consumo de alimentos para adultos ecuatorianos, estudio transversal

Abstract

Introduction: Dietary surveys include food consumption frequency questionnaire (CFCA) is an inexpensive method, relatively easy to apply, and necessary for the evaluation of the diet of individuals and populations. The objective of this study was to develop an FFQ for the Ecuadorian adult population. Material and Methods: Cross-sectional study, in 255 adult individuals of both sexes between 18 and 68 years old residing in 10 provinces of Ecuador. A 24-hour reminder (R24h) was applied to obtain information on the dietary consumption of the population and the construction of the instrument. The preparation of the list of foods that make up the CFCA was made from the percentage contribution of each food for the total estimate of energy and nutrients of interest, using the Block method. Results: An instrument composed of 91 items distributed in 7 categories were obtained. The instrument was reviewed by experts from 4 universities belonging to the region, coast, highlands, and Amazon of Ecuador. Conclusions: This instrument makes an approximation of the dietary consumption of the three regions of continental Ecuador.
