Tag: Ffq validation

Food frequency questionnaires (FFQs) are a widely used, yet imperfect, tool in nutritional epidemiology, and studies show they can sometimes overestimate or underestimate certain intakes. Understanding how do you validate an FFQ is crucial for researchers to ensure their dietary data is accurate, reliable, and applicable to their specific study population.

According to the National Cancer Institute, food frequency questionnaires (FFQs) are one of the most common dietary assessment methods in large-scale epidemiological studies. The most significant advantage of using food frequency questionnaires to assess nutritional status is their ability to capture long-term, habitual dietary patterns, which is critical for studying chronic diseases that develop over many years.

Food frequency questionnaires (FFQs) are among the most common tools in nutritional epidemiology because of their low cost and capacity to capture long-term dietary patterns. However, a non-validated FFQ can introduce serious errors into a study, highlighting the need to properly validate a food frequency questionnaire to ensure its accuracy.
