Assessing the relative validity of a new, web-based, self-administered 24 h dietary recall in a French-Canadian population.

ABSTRACT:

Objective

To assess the relative validity of a new, web-based, self-administered 24 h dietary recall, the R24W, for assessment of energy and nutrient intakes among French Canadians.

Design

Each participant completed a 3d food record (FR) and the R24W on three occasions over a 4-week period. Intakes of energy and of twenty-four selected nutrients assessed by both methods were compared.

Setting

Québec City metropolitan area.

Subjects

Fifty-seven women and fifty men (mean (sd) age: 47·2 (13·3) years).

Results

Equivalent proportions of under-reporters were found with the R24W (15·0%) and the FR (23·4%). Mean (sd) energy intake from the R24W was 7·2% higher than that from the FR (10 857 (3184) kJ/d (2595 (761) kcal/d) v. 10 075 (2971) kJ/d (2408 (710) kcal/d)
