    Background

    A pilot study was carried out to evaluate the relative validity and reproducibility of a dietary history questionnaire (DH) designed to be used in Spain as part of a prospective European research project on diet and cancer.

    Twelve 24-hour diet recalls, administered monthly between the two administrations of the DH, were used as a reference method.

    Natural units, geometric figures and a set of photographs were used to quantify portion size.

    Results

    Of a total of 17 food groups, the Pearson correlation coefficients between the daily intake of food groups, based on the mean of 12 24-hour diet recalls, and the second DH showed values between 0.65 and 0.90 in 14 groups (potatoes, vegetables, fruits, cheese, other dairy products, bread, other cereals, meat and poultry, fish and shellfish, butter, margarine and oils, sugar and sweets, other desserts, alcohol and coffee and tea) in males and in 11 groups (potatoes, other vegetables, fruits, cheese, other dairy products, bread, meat and poultry, fish and shellfish, sugar and sweets, alcohol and coffee and tea) in females.
