“…This study presents good reproducibility and validity of some nutrients, which will help us better understand the ELSA-Brasil population's food compartment. The nutrients evaluated in this study show good reproducibility, finding ICC values (0.51-0.70); these values were similar and comparable to other FFQs [18][19][20][21][22] . In Moroccan adults with an average age of 23.7 years, the reproducibility of a FFQ was evaluated, finding an agreement for macro (between 0.69-0.75 for fat and protein, respectively) and micronutrients (above 0,7 for majority micronutrients) 23 .…”

Background: To investigate the association between diet and health effects in population surveys, it is necessary to have precise tools that allow estimating the habitual consumption of the population. Introduction: To investigate the association between diet and health effects in population surveys, it is necessary to have precise tools that allow estimating the habitual consumption of the population. Aim: To evaluate the reproducibility and validity of the ELSA-Brasil food frequency questionnaire (FFQ) to assess macro and micronutrients intake. Material and methods: We collected dietary information of 281 participants which completed two ELSA-Brasil food frequency questionnaires (FFQ) over a year period and three records. To assess the reproducibility of the FFQ, we compared the macro and micronutrients intake from the two FFQ while to assess the validity, we compared the intakes of FFQ with the mean of three records. The intraclass correlation test (ICC) and agreement percentages of nutrient intake were calculated after categorization by tertiles. Results: ICC coefficients for reproducibility ranged from 0.51 (polyunsaturated fat) to 0.70 (magnesium) while the ICC coefficients for validity ranged from 0.14 to 0.61 for omega 3 and magnesium, respectively. The exact concordances between methods ranged from 37% for omega 3 to 50.2% for magnesium (mean = 44.6%). An average disagreement of 13.4% was found. Conclusions: This study suggests that the ELSA-Brasil FFQ is suitable tool to assess dietary intake with a satisfactory reproducibility and relative validity.

“…Sabe-se que essa variabilidade, quando não corrigida, pode atenuar os coeficientes de correlação 32 . No entanto, mesmo não corrigidos, os coeficientes obtidos foram, em geral, mais altos do que aqueles vistos nos estudos de validação por nutrientes 7,14 .…”

OBJETIVO: Testar reprodutibilidade e validade por grupos de alimentos de um questionário de frequência alimentar, desenvolvido para indivíduos adultos residentes no Sul do Brasil. MÉTODOS: Dois questionários de frequência alimentar e três inquéritos recordatórios de 24 horas foram aplicados a 128 participantes, com idade entre 20 e 69 anos. Os alimentos foram agrupados em 19 grupos previamente definidos. As análises foram realizadas com dados brutos e corrigidos pela energia. RESULTADOS: Apenas nas estimativas de ingestão dos grupos de folhosos e de leguminosas observaram-se diferenças estatisticamente significantes entre os dois questionários de frequência alimentar. Os coeficientes de correlação, corrigidos pela energia, entre os questionários variaram de 0,53 (embutidos e presuntos) a 0,85 (bebidas alcoólicas e leite e derivados light). Quanto à validade, ambos os questionários produziram tanto estimativas de ingestão mais altas como mais baixas do que a média dos inquéritos recordatórios de 24 horas. O coeficiente de correlação médio entre cada questionário e os inquéritos recordatórios de 24 horas foi de 0,39 para o questionário de frequência alimentar 1, e de 0,40 para o questionário de frequência alimentar 2. Os coeficientes de correlação foram iguais ou maiores que 0,40 para 9 grupos alimentares no questionário de frequência alimentar 1, e para 11 grupos no questionário de frequência alimentar 2. Os percentuais médios de classificação no mesmo terço, pelos dois métodos, foram 49% para o questionário de frequência alimentar 1, e 48% para o questionário de frequência alimentar 2. Os valores de Kappa ponderado variaram de -0,04 (bebidas não-alcoólicas) a 0,69 (leite e derivados light), considerando ambos os questionários. CONCLUSÃO: O questionário de frequência alimentar baseado em grupos de alimentos representa uma boa alternativa para avaliar o hábito alimentar, com a vantagem de ter uma lista reduzida de itens alimentares.

“…It is important to note that, likewise, when used in validation and reproducibility studies of food survey instruments, participants' classification according to the quartile distribution can both group individuals with different levels of meal quality into the same category, as well as put into different categories those with similar levels, if they are very close to the cut-off point [29]. Since the sample size used was within the range recommended for validation studies, there is a relative reduction of this bias [30].…”

Objective To assess agreement between two meal quality indexes adapted for elderly people, evidencing their similarities and differences Methods Agreement study with 322 institutionalized elderly individuals. Food consumption data were collected by the method of weighted food record, in two nonconsecutive days. The Meal Quality Index and the Main Meal Quality Index of each older adult were calculated for the lunch meal. Agreement between methods was tested by cross-classification in quartiles and weighted kappa (Kw), and the difference between medians by the Wilcoxon test. Results The Meal Quality Index median was 54.67 points and the Main Meal Quality Index 53.51 points (p=0.723). When the components of each index were assessed, those associated to the consumption of carbohydrates, total fat and saturated fat were similar. The consumption of fruits separated from vegetables in the Main MealQuality Index evidenced low consumption of vegetables by the elderly. Cross-classification by quartiles showed good agreement; the exact one being 48.8% and the disagreement 3.4% (Kw=0,447). The proportion of elderlyindividuals in the same exact or adjacent quartile was greater than 85.0%. Agreement was higher in males (89.4%, Kw=0.475); in the age range of 70 to 79 years (91.1%; Kw=0.562) and in non-profit nursing homes(96.7%; Kw=0.622). Conclusion The two indexes reviewed show a good agreement between them and common characteristics. The number of components is higher in the MMQI and may represent a more detailed assessment of meal quality.
