RESUMO
This study aimed to validate a semiquantitative electronic food frequency questionnaire (eFFQ) in estimating the intake of a comprehensive list of nutrients and bioactive compounds among adults from six regions of Argentina using multiple 24 h dietary recall (24HR) as a reference. A total of 163 adults completed two administrations of the eFFQ and four 24HRs. The paired t-test/Wilcoxon signed-rank test, Spearman/Pearson correlations, cross-classification, weighted kappa statistics, and Bland-Altman plots were employed to determine relative validity. To determine reproducibility, intraclass correlations (ICC), cross-classification, and weighted kappa statistics were calculated. For relative validity, crude correlations ranged from 0.15 to 0.57; energy adjustment and de-attenuation slightly improved most of these correlations. In cross-classification analysis, agreements within one quintile adjacent to exact agreement (EA ± 1) ranged from 52.2% to ~74%; extreme misclassifications were < 7%. For reproducibility, the crude ICC ranged from 0.29 to 0.85, showing moderate to good correlations for most nutrients. Cross-classification analysis showed agreement levels for the EA ± 1 quintile of 70.6% to 87.7%. Weighted kappa values ranged from 0.21 to 0.62. The results show that this eFFQ is relatively valid in ranking adults according to their nutrient intake and has an acceptable reproducibility, yet it slightly overestimates the intake of most nutrients.

Background: Latin American countries show a fast-growing rate of non-communicable diseases (NCDs) and diet is a critical risk factor that must be properly assessed. Automated dietary assessment tools to collect 24-h dietary recalls (24HR) are lacking in Argentina. Objective: This study aimed to develop an open-access automated tool (MAR24) for collecting 24HR using a multiple pass method and a database containing foods and recipes commonly consumed in Argentina. Methods: MAR24 was developed based on data from 1,285 24HR provided by male and female participants aged 18 to 68 years from the six Argentinian geographical regions. The main structure and interface of the tool were designed using Visual Basic for Applications programming language in Excel Microsoft Office 365, integrating the five steps of the United States Department of Agriculture (USDA) Automated Multiple-Pass Method (AMPM) for the application of 24HR in Spanish. The tool underwent alpha testing and expert assessment to address structural and usability issues. Critical feedback and face validation from researchers and experienced dietitians, and repeated testing to collect 24HR were used to adjust and improve the tool. Results: A total of 968 food items and 100 standard Argentinian recipes were added to its database. MAR24 allows the estimation of the nutrient profile of dietary intake. The analytic food composition includes energy and 50 nutrients including water, macronutrients, total dietary fiber, total sugar, 10 minerals, 19 vitamins, eight fatty acids, cholesterol, ethyl alcohol, caffeine, and theobromine. MAR24 includes a user manual and technical manual to guide users to apply changes (e.g., add foods or recipes, or change food designation according to local terms) to fit different research and clinical applications. Conclusions: MAR24 is the first tool that uses the AMPM methodology for 24HR applications in Argentina. The tool may be used in clinical practice and clinical trials for monitoring purposes, and in validation of food frequency questionnaires (FFQ) for nutritional epidemiology studies addressing dietary-associated risk factors for NCDs.
RESUMO
Although current research has contributed to the promotion of whole-food plant-based diets, few studies have examined healthy vegan dietary and lifestyle factors, especially in South America. Therefore, we aimed at investigating the adherence to healthy vegan lifestyle habits among Argentinian vegetarians and omnivorous, using a recently developed vegetarian lifestyle index adapted to the vegan dietary pattern. Also, accessibility of vegetarian foods, and the proportion of household income spent on food were assessed in a cross-sectional approach with 1454 participants. The population was comprised of females (84.9%), singles (55.0%), young-adults (mean age 32.1, standard deviation (SD) = 13.6), employed (50.8%), with high educational levels (50.4%), and low prevalence of both tobacco smoking (7.0%) and frequent alcohol consumption (7.6%). The mean score of adherence to healthy vegan lifestyle habits was 6.64 (SD = 1.72), with higher scores indicating better adherence. Non-vegetarians (5.75; 95% confidence interval (CI), 5.61â»5.89) had a significantly lower adjusted mean score compared to semi-(6.32; 95% CI, 6.17â»6.47), pesco-(6.99; 95% CI, 6.59â»7.39), lacto-ovo-vegetarians (7.10; 95% CI, 6.96â»7.24), as well as vegans (8.59; 95% CI, 8.35â»8.83). The mean proportion of household income spent on food was significantly lower among vegans compared with other dietary patterns. The whole studied population showed a low consumption of whole grains, legumes, vegetables, nuts, and seeds. Although vegans showed a better diet and lifestyle pattern there is a need to improve eating and lifestyle habits to address risk factors for non-communicable diseases in Argentina.

Objetivos: Esta investigación desarrollada durante los meses de agosto, septiembre y octubre de 2013- tuvo como objetivo identicar el riesgo de padecer trastornos de la conducta alimentaria en estudiantes cursantes de 1º a 5º año de la carrera de Licenciatura en Nutrición en cinco universidades de Argentina. Materiales y métodos: el diseño del estudio es descriptivo y de corte transversal. El instrumento que se utilizó para recolectar los datos es el Test de Actitudes Alimenticias-26. Resultados y conclusiones: la investigación muestra que los estudiantes presentaron un 13,3% de riesgo de padecer trastornos de la conducta alimentaria, encontrándose que, según la universidad a la que asisten, existe mayor o menor riesgo de presentar trastornos de la conducta alimentaria (TCA). En relación al estado nutricional de los alumnos se observó que aquellos que mostraron sobrepeso y obesidad presentaron mayor riesgo de padecer TCA. El estudio reflejó la gran preocupación de los estudiantes en relación con los alimentos que ingieren y la posibilidad de aumentar su peso corporal. Al detectarse que pueden existir casos de alumnos de la Carrera de Nutrición con algún tipo de TCA, se recomiendan medidas preventivas en relación a este tema y al correcto tratamiento y/o derivación en los casos diagnosticados.
Objetives: The purpose of this study is to identify the risk of developing eating disorders in students from 1st to 5th year of the degree in Nutrition from ¬ve universities in Argentina. It was developed during the months of August, September and October 2013. Materials and methods: the study design is descriptive and cross-sectional, and the measure used to collect the data is the Eating Attitudes Test-26 (EAT-26). Results and conclusions: this research shows that students have 13,3% risk of developing eating disorders. It was found that depending on the University attended by students, there is a greater or lesser risk of eating disorders. It was observed that those who are overweight and obese are at increased risk for these diseases regarding nutritional status of students. It is notorious the concern among students about food and weight gain. This shows that there might be cases of Nutrition students with some sort of eating disorders. That is why we recommend taking preventive measures in relation to this issue and the correct treatment or referral in diagnosed cases.
