International conference on dietary assessment methods : assessing diets to improve world health. Saint Paul MN (USA), 1992/09/20.
Semiquantitative food-frequency (SQFF) questionnaires have been used by many epidemiological studies to collect dietary data.
These methods are especially attractive for use in large-scale studies because they are often self-administered and/or completed with minimal time or effort.
This paper discusses several statistical issues related to the use of dietary data collected by frequency methods.
In particular, the paper addresses 1) whether SQFF methods are well-validated dietary methods as suggested by many investigators and 2) whether data based on SQFF methods can be used to compare mean dietary intakes among different populations and to estimate the distribution of usual nutrient intakes in a national probability population.
