Food Frequency Questionnaire (FFQ)

Food Frequency Questionnaire (FFQ) methods are the mainstay of work in observational epidemiology. The Center has extensive experience in designing and testing instruments to capture specific nutrients and is able to modify them to conform to the specific needs and requirements of study populations. Methods are utilized to improve precision and accuracy in epidemiologic studies by identifying relevant biases and developing methods of control when performing statistical analyses. Theoretically, a single administration of an FFQ provides an estimate of usual, habitual intake. Administration takes about 30-45 minutes to complete and can be either a self-administered or interviewer-administered instrument.
