Introduction The food frequency questionnaire is widely regarded as more appropriate for ranking and grouping individuals according to levels of nutrient intake than for estimating absolute nutrient amounts. Aims To develop a method for estimation of amount of nutrient intake from food frequency questionnaires by reference to an independent weighed dietary survey. Method Six stages of the method are described and illustrated in the estimation of total dietary fat from the 1984–85 Health and Lifestyle Survey using the 1986–87 Dietary and Nutritional Survey of British Adults as the reference standard. Results Several points support the validity of the approach although limitations are identified. [ABSTRACT FROM AUTHOR] |
