Abstract

MARTIN-CESPEDES, Mónica et al. Comparison of three short methods against a standard method to analyze the nutritional composition of food consumption surveys of Costa Rican adults. PSM [online]. 2020, vol.17, n.2, pp.20-42. ISSN 1659-0201.  http://dx.doi.org/10.15517/psm.v17i2.39974.

Objective: comparison of three short methods for analysis of food consumption data from a group of Costa Rican adults. Methodology: 100 questionnaires from 24-hour recalls were obtained from the Latin American Study of Nutrition and Health. Three short methods for dietary analysis based on two different exchange lists and a new food group system proposed by the researchers) were compared to a standard method based on food composition tables. The values ​​obtained were compared using the Wilcoxon signed-rank test, Spearman´s rank correlation coefficient and the Bland-Altman plot. Results: the food group system is the short method of diet whose results are more similar to the standard method in terms of energy, macro and micronutrients. In the ADA exchange lists, carbohydrates are underestimated (-19.2%) and fats are overestimated (53.8%). The Colombian exchange lists resulted in significant differences and lower correlation coefficients for sodium (0.692) and fatty acids (0.758). Conclusion: the food group system is the method that presents results which are more similar to the standard method for dietary analysis and is considered easier to use in clinical practice.
