Usual Dietary Intakes: NHANES Food Frequency Questionnaire (FFQ)

NCI developed a new instrument called the NHANES Food Frequency Questionnaire (formerly called Food Propensity Questionnaire) and supported its application in the National Health and Nutrition Examination Survey (NHANES). This instrument collects much of the same information as a food frequency questionnaire (FFQ), but without asking about portion size. The resulting data can be employed in the NCI usual dietary intakes model as covariates. By not asking about portion size, the NHANES FFQ requires less respondent burden than other FFQs.
