Validation of a self-administered web-based 24-hour dietary recall among pregnant women.


ABSTRACT: BACKGROUND:The use of valid dietary assessment methods is crucial to analyse adherence to dietary recommendations among pregnant women. This study aims to assess the relative validity of a self-administered Web-based 24-h dietary recall, the R24W, against a pen-paper 3-day food record (FR) among pregnant women. METHODS:Sixty (60) pregnant women recruited at 9.3?±?0.7 weeks of pregnancy in Quebec City completed, at each trimester, 3 R24W and a 3-day FR. Mean energy and nutrient intakes reported by both tools were compared using paired Student T-Tests. Pearson correlations were used to analyze the association between both methods. Agreement between the two methods was evaluated using cross-classification analyses, weighted kappa coefficients and Bland-Altman analyses. RESULTS:Pearson correlation coefficients were all significant, except for vitamin B12 (r?=?0.03; p?=?0.83) and ranged from 0.27 to 0.76 (p?
