Dietary Assessment


Diet, in all its complexity, is considered one of the major risk factors for cancer. The Epidemiology and Genomics Research Program's (EGRP) goals in this area are to increase the precision of dietary intake estimates by improving self-report of dietary intake and the analytic procedures for processing reported information. This work is designed to facilitate dietary monitoring and nutritional epidemiology efforts and to advance our understanding of the relationship of diet to cancer outcomes.

Selected Projects

Examples of current and past collaborative projects related to dietary assessment in which EGRP staff are involved:

Significant past initiatives EGRP has been involved with include:

  • Eating at America's Table Study (EATS)
    Study, completed in 1999, that was designed to validate the Diet History Questionnaire (DHQ), an improved food frequency questionnaire (FFQ) developed by NCI staff. The study examined not only the DHQ, but also two other widely used FFQs. In addition, within the overall study, investigators evaluated the validity of two new short dietary assessment instruments developed by NCI staff.
  • Genes, Environment and Health Initiative (GEI)
    The GEI was established in 2006 to lay a foundation for investigating the interaction between environmental and genetic underpinnings of human disease. The trans-NIH Initiative consisted of two major components: identifying genetic susceptibility factors for diseases that have a high public health impact and developing new technologies for accurate measurement of environmental exposures and lifestyle factors. This link provides more information about selected publications and studies associated with the exposure biology portion of GEI.
  • Observing Protein and Energy Nutrition Study
    NCI-sponsored study, completed in 2000, designed to assess dietary measurement error by comparing results from self-reported dietary intake data with four dietary biomarkers: doubly labeled water and urinary nitrogen, sodium, and potassium.
