“…15 The questionnaire used in our study has been validated for accuracy of recall over a 2-year period. 16 Weekly consumption of peanut protein for each family member was calculated from data on precise peanut protein content of different foods. Total weekly household peanut consumption (referred to as household peanut) for the first year of life was calculated by adding the weekly consumption of all family members resident in the household during this period.…”

“…This FFQ had been validated previously for recall but has not been validated against a gold standard. 7 Eighteen high-peanut protein containing food items were also included. To make the latter list as accurate and complete as possible, we made use of both the pediatric dietitians’ peanut avoidance diet sheets (that lists common peanut-containing foods), and the Anaphylaxis Campaign (a charitable organization that offers support to the families of children with allergies) food lists.…”

Background:Food frequency questionnaires (FFQs) are essential tools to investigate the relationship between peanut consumption and the development of peanut allergy. The aim was to validate a 50-item FFQ for use in peanut protein sensitization studies.Methods:There were 38 mother-child pairs visiting a pediatric clinic of a London hospital included. Mothers recorded their own and their child's diet, using a 7 day food diary (7DFDR), completed prospectively over week. Six months later, they tried to recall the consumption of food items for the index week on a FFQ.Results:Of these, 33 out of 38 mothers completed both the 7DFDR and the recall FFQ. Although there was considerable variation at the individual level between the 2 tools, there was extremely close agreement between the mean 7DFDR response and the FFQ when considering groups of fives with similar FFQ levels. Agreement was apparent on both peanut and other control foods consumption patterns.Conclusion:The FFQ will reliably divide the population into groups with markedly different peanut consumption levels. It accurately reflects true adults and children peanut consumption, especially at low levels of peanut consumption, as it was validated against the gold standard, the 7DFDR. It also provides a good measure of other foods consumption.

Background Research investigating the association of infant dietary factors with later health outcomes often relies on maternal recall. It is unclear what the effect of recall bias is on the accuracy of the information obtained. The present study aimed to determine the extent of recall bias on the accuracy of infant feeding and food allergen data collected 10 years later. Methods Mothers were recruited from a prospective birth cohort from the Isle of Wight. When their child was 10 years of age (2011/2012), mothers were requested to complete a retrospective infant feeding questionnaire asking the same questions as those solicited in 2001/2002. Results In total, 125 mothers participated. There was substantial agreement for recollection of any breastfeeding (κ = 0.79) and the duration of breastfeeding from 10 years earlier (r = 0.84). Some 94% of mothers recalled accurately that their child had received formula milk. The exact age at which formula milk was first given was reliably answered (r = 0.63). The brand of formula milk was poorly recalled. Recall of age of introduction of solid food was not reliable (r = 0.16). The age of introduction of peanuts was the only food allergen that was recalled accurately (86%). Conclusions The present study highlights the importance of maternal recall bias of infant feeding practices over 10 years. Recall related to breastfeeding and formula feeding were reliable, whereas recalls related to age of introduction of solid or allergenic foods, apart from peanut, were not. Caution should be applied when interpreting studies relying on dietary recall.
