“…[23], and 13 of 30 achieved a correlation greater than or equal to the “desirable” .5 proposed by Masson et al [42]. The average unadjusted correlation coefficient of .47 compared favorably with the range reported by similar validation studies comparing FFQ with food records: .34-.46 [31-32,34,41]. SCC for food group intakes were highly variable, ranging from .11 (soups, sauces and miscellaneous foods) to .73 (yogurts), with a mean value of .2.…”

BackgroundAdvances in nutritional assessment are continuing to embrace developments in computer technology. The online Food4Me food frequency questionnaire (FFQ) was created as an electronic system for the collection of nutrient intake data. To ensure its accuracy in assessing both nutrient and food group intake, further validation against data obtained using a reliable, but independent, instrument and assessment of its reproducibility are required.ObjectiveThe aim was to assess the reproducibility and validity of the Food4Me FFQ against a 4-day weighed food record (WFR).MethodsReproducibility of the Food4Me FFQ was assessed using test-retest methodology by asking participants to complete the FFQ on 2 occasions 4 weeks apart. To assess the validity of the Food4Me FFQ against the 4-day WFR, half the participants were also asked to complete a 4-day WFR 1 week after the first administration of the Food4Me FFQ. Level of agreement between nutrient and food group intakes estimated by the repeated Food4Me FFQ and the Food4Me FFQ and 4-day WFR were evaluated using Bland-Altman methodology and classification into quartiles of daily intake. Crude unadjusted correlation coefficients were also calculated for nutrient and food group intakes.ResultsIn total, 100 people participated in the assessment of reproducibility (mean age 32, SD 12 years), and 49 of these (mean age 27, SD 8 years) also took part in the assessment of validity. Crude unadjusted correlations for repeated Food4Me FFQ ranged from .65 (vitamin D) to .90 (alcohol). The mean cross-classification into “exact agreement plus adjacent” was 92% for both nutrient and food group intakes, and Bland-Altman plots showed good agreement for energy-adjusted macronutrient intakes. Agreement between the Food4Me FFQ and 4-day WFR varied, with crude unadjusted correlations ranging from .23 (vitamin D) to .65 (protein, % total energy) for nutrient intakes and .11 (soups, sauces and miscellaneous foods) to .73 (yogurts) for food group intake. The mean cross-classification into “exact agreement plus adjacent” was 80% and 78% for nutrient and food group intake, respectively. There were no significant differences between energy intakes estimated using the Food4Me FFQ and 4-day WFR, and Bland-Altman plots showed good agreement for both energy and energy-controlled nutrient intakes.ConclusionsThe results demonstrate that the online Food4Me FFQ is reproducible for assessing nutrient and food group intake and has moderate agreement with the 4-day WFR for assessing energy and energy-adjusted nutrient intakes. The Food4Me FFQ is a suitable online tool for assessing dietary intake in healthy adults.

Este estudo testou reprodutibilidade e validade relativa, e estimou fatores de calibração de um QFA (questionário de frequência alimentar) com 120 itens alimentares, em 128 adultos. Aplicou-se um QFA e três inquéritos recordatórios de 24hs (IR24h). A validade foi testada pelo método de Bland-Altman, correlação intraclasse (CCI), classificação em quartos de ingestão e kappa ponderado. Os fatores de calibração foram estimados por meio de regressão linear, com os valores de ingestão alimentar do IR24h como variável dependente e os valores do QFA como variável independente. O QFA subestimou a ingestão da maioria dos nutrientes em relação ao IR24h. O CCI corrigido para energia e deatenuado variou de 0,19 (zinco) a 0,82 (cálcio). Trinta e sete por cento dos indivíduos foram classificados no mesmo quarto, com valor médio de kappa de 0,28 (zinco: 0,08; cálcio: 0,49). Os maiores fatores de calibração foram 0,48 (cálcio), 0,47 (potássio) e 0,44 (carboidratos), e o menor fator foi 0,10 (retinol). Esse QFA demonstrou validade relativa satisfatória e valores de ingestão de energia e nutrientes calibrados semelhantes ao IR24h.
