  1. Fulltext. Dietary assessment in epidemiology : Comparison of a food frequency and a diet history questionnaire with a 7-day food record.

    Article - En anglais

    Fulltext.

    The validity of two types of diet assessment methods, a self-administered food frequency questionnaire and an interviewer-administered detailed diet history, was assessed relative to a 7-day food record on a population-based sample of 95 men and 108 women in Toronto, Canada, between May 1989 and July 1990.

    Each study subject completed both questionnaire methods, a food frequency questionnaire and an interviewer-administered diet history, as well as a 7-day food record in a crossover design.

    Data were analyzed for both unadjusted and energy-adjusted nutrients to estimate Pearson's and intraclass correlations and agreement within categories.

    Mean values for the intake of most nutrients assessed by the two questionnaire methods were similar.

    Average, energy-adjusted Pearson's correlation coefficients for men between a food frequency questionnaire and a 7-day food record were 0.55 for macronutrients and 0.48 for micronutrients compared with 0.47 for macro-and 0.48 for micronutrients between an interviewer-administered diet history and a 7-day food record.

    For women, they were 0.48 for macro-and 0.54 for micronutrients between a food frequency questionnaire and a 7-day food record and 0.46 and 0.49, respectively, between an interviewer-administered diet history and a 7-day food record.

    The energy-adjusted Pearson correlations were generally higher than were the energy-unadjusted Pearson correlations and the intraclass correlations.

    The present study suggests th...
