“…Furthermore, Molag et al 48 observed that correlation coefficients of studies that used a time interval of between eight and 14 days were significantly higher than in studies that used a time interval of between one to seven days. Pereira et al 49 , in an analysis of dietary intake in adults, observed a high degree of within and between-subject variance, with values of up to 15.6 for cholesterol in men. These authors showed that the number of replications needed to estimate usual energy and nutrient intake depends on the nutrient being analyzed and on the expected correlation coefficient: for example, to achieve an expected correlation coefficient of 0.7 requires an average of eight replications within a range of one (for carbohydrates) to 15 (for cholesterol).…”

“…Molag et al 34 , em estudo de meta-análise com 40 artigos de validação de QFA, verificaram que os coeficientes de correlação eram mais elevados quando o méto-do de referência foi aplicado por 8 a 14 dias em comparação a replicações que variavam de um a sete dias. Mais ainda, Pereira et al 35 relataram que para adolescentes do Rio de Janeiro a estimativa de consumo usual com erro máximo de 10% pode requerer até 15 replicações de recordatórios de 24 horas ou registros alimentares. Embora tenham sido empregados procedimentos para minimizar a subestimação no método de referencia, como o uso de imagens de utensílios e a sondagem para alimentos usualmente omitidos, é possível que tenha ocorrido algum grau de subestimação do consumo com o R24h, o que incorreria na minimização dos estimadores da validade do QFA com suporte de fotografias.…”

“…3 , 9 Properly designed nutritional research that includes dietary assessment should thus consider the number of subjects required in 1 group (group size) and the number of days required to implement the assessment efficiently. 3 , 10 These variables can be estimated using within- and between-individual variation of nutrient intake.…”

BackgroundInformation on within- and between-individual variation in energy and nutrient intake is critical for precisely estimating usual dietary intake; however, data from Japanese populations are limited.MethodsWe used dietary records to examine within- and between-individual variation by age and sex in the intake of energy and 31 selected nutrients among Japanese adults. We also calculated the group size required to estimate mean intake for a group and number of days required both to rank individuals within a group and to assess an individual’s usual intake, all with appropriate arbitrary precision. A group of Japanese women (younger: 30–49 years, n = 58; older: 50–69 years, n = 63) and men (younger: 30–49 years, n = 54; older: 50–76 years, n = 67) completed dietary records for 4 nonconsecutive days in each season (16 days in total).ResultsCoefficients of within-individual variation and between-individual variation were generally larger in the younger group than in the older group and in men as compared with women. The group size required to estimate a group’s mean intake, and number of days required to assess an individual’s usual intake, were generally larger for the younger group and for men. In general, a longer period was required to rank women and older adults.ConclusionsIn a group of Japanese adults, coefficients of within-individual variation and between-individual variation, which were used to estimate the group size and number of records required for adequate dietary assessment, differed by age, sex, and nutrient.
