Dietary habits vary widely among regions and cultural groups, and FFQ need to be designed for specific populations. The objectives of the present study were to develop and test the repeatability and relative validity of a medium-length semi-quantitative FFQ for measuring the energy and macronutrient intakes of a specific population and to contribute a methodological framework for this procedure.
Palestinian families in the Hebron area.
After a preliminary survey of a subgroup of homemakers using 3 d diet recall, stepwise multiple regression analysis was used for selected nutrients to choose foods for inclusion in the FFQ.
The FFQ was administered to a study population of 169 women representing the same number of families.
The Wilcoxon test and Bland–Altman plots were used to compare the FFQ results with the mean 3 d diet recall results. A high level of concordance was found, validating the FFQ. In this population, the mean consumption of SFA was above recommendations and the intakes of vitamin D, folic acid, Ca, Fe and K were deficient.
The availability of diet assessment instruments designed for specific populations and cultures is of immense value to researchers and policy makers. The study describes a simple and effective method to develop and validate an FFQ for a given population of interest.
