  1. Validity of individual portion size estimates in a food frequency questionnaire.

    Article - En anglais


    Dietary surveys often rely upon subjects'ability to estimate their portion sizes instead of weighing them, but information on the validity of such estimates is lacking.

    This study investigated the validity of estimated portion sizes from a self-administered food frequency questionnaire including photos.


    Validity was evaluated by comparison with portion sizes from 14-day weighed food records.

    Eight sets of photos were included in the study (three meat dishes, one fish dish, three vegetables, potatoes), each set with four options.
