“…A 24-h recall instrument asking about fruit and vegetable intake similar to the one validated in the present study was validated against precoded food diaries, among 12-year old Norwegian children (Andersen et al, 2004). The 24-h recall overestimated the intake of fruit and fruit juice compared to the reference method, while there was no significant difference observed for vegetable intake.…”

Objective: To validate a method for assessing fruit and vegetable intake among adults in a population of low intake. The method assesses mean intake and ranks individuals by their usual intake. Design: A precoded fruit and vegetable Questionnaire included a 24-h recall and a food frequency. The participants filled in the Questionnaire, a week later they started a 7-day food record, 1-day weighed record and 6 days using household measures. Subjects: Following advertisements 40 participants were recruited, 36 returned food records(mean age ¼ 37 years). Results: No difference was observed between the average intake yielded by the 24-h recall and that from the 1-day weighed food record of fruits or vegetables. Correlation coefficients between results from the food frequency questionnaire and the 7-day food records were 0.45 (P ¼ 0.007) for vegetables, 0.63 (Po0.001) for fruits and 0.73 (Po0.001) for fruits and vegetables combined. Cross-classification into quartiles showed that the proportion of participants in the same or the adjacent quartile of the intake distribution were 94% for fruit intake and 80% for vegetable intake. Registered intake of fruits and vegetables was higher the first 4 days of the record than the last 3 days (P ¼ 0.002). The 4-day food record correlated with the food frequency questionnaire in similar manner as the 7-day record. Conclusion: The present study indicates that the precoded 24-h recall may be valuable tool for measuring average intake of fruits and vegetables among adults in a population of low intake. Moreover, the food frequency questionnaire was valid for ranking individuals according to their usual intake. A 4-day food record might be sufficient when validating food frequency questionnaires for fruits and vegetables.

“…Structure of the questionnaire A Questionnaire was developed from validated tools used to measure the effects of fruit and vegetable subscription in schools in Denmark and Norway (Eriksen et al, 2003;Andersen et al, 2004). The optically scannable Questionnaire was composed of a 24-h recall part and a food frequency part.…”

“…No entanto, análises do padrão do consumo por refeição têm merecido menos atenção 25 . O terceiro ponto positivo refere-se ao fato de o QUADA-3 ser resultado de sucessivos estudos de validação, que serviram para aprimorar o seu design e aperfeiçoar os respectivos protocolos, premissas também reforçadas em outros estudos 1,5,22 . Deve-se ressaltar, ainda, que o QUADA foi desenvolvido considerando o estágio cognitivo das crianças de 7 a 10 anos de idade.…”

“…Outros estudos de validação de questionários estruturados do dia anterior também reportaram menor precisão de informação para as categorias alimentares que incluíam vários tipos de alimentos ao invés de alimentos específicos (por exemplo, "verduras" em vez de "cenoura" ou "alface"; "doces" em vez de "sorvetes" ou "balas") 5,22 .…”

Validação da terceira versão do Questionário Alimentar do Dia Anterior (QUADA-3) para escolares de 6 a 11 anos

et al. 2009

O estudo objetivou conferir validade à terceira versão do Questionário Alimentar do Dia Anterior (QUADA-3) para escolares. O QUADA-3 é um instrumento estruturado com seis refeições e 21 alimentos. Participaram 164 escolares de 6 a 11 anos de idade, de uma escola pública de período integral, em 2007. A validade foi testada pela comparação entre os itens alimentares selecionados no questionário e a observação direta de alimentos consumidos em três refeições escolares do dia anterior (lanche da manhã, almoço, lanche da tarde). Análise de regressão logística multivariada foi conduzida para avaliar a discordância entre as respostas do questionário e o registro das observações. Os resultados indicaram alta sensibilidade e especificidade para a maioria dos itens alimentares. Em média, os valores de sensibilidade e especificidade foram de 70,2% e de 96,2%, respectivamente, para os 12 itens alimentares nas três refeições combinadas. Os escolares de 6 a 8 anos, quando comparados aos de 9 a 11 anos, apresentam maiores taxas de discordância de respostas entre o QUADA-3 e as observações. Os resultados indicaram que o QUADA-3 pode gerar dados válidos para avaliar o consumo alimentar do dia anterior em nível de grupo de escolares.
