Risk Factor Assessment
The Risk Factor Assessment Branch in NCI’s Epidemiology and Genomics Research Program supports research into areas including:
- diet and physical activity metrics
- methods, tools, technologies, and resources for risk factor assessment
- obesity policy research
Learn more about RFAB’s interests in the following areas, relevant funding opportunity announcements, related EGRP events, and staff contacts.
EGRP partners with others at NIH, NIH, and other organizations to increase the precision of dietary intake estimates by improving self-report of dietary intake and the analytic procedures for processing reported information. This research will facilitate dietary monitoring and nutritional epidemiology efforts and to advance our understanding of the relationship of diet to cancer outcomes.
Physical Activity Assessment
EGRP partners with others at NIH, NIH, and other organizations to support the collection of physical activity data in existing and planned surveys. Doing so will develop more complete assessments of individuals' physical activity based on information derived from multiple contexts, including transportation, occupation, and recreation.
Obesity Policy Research
EGRP partners with others at NIH, NIH, and other organizations to support various initiatives in obesity policy research, including research on diet and physical activity that may inform policymaking at local, state, or federal levels and measurement of the food and physical activity environments.
Automated Self-Administered 24-Hour Diet Assessment Tool (ASA24)
ASA24 is a freely available web-based tool for epidemiologic, interventional, behavioral, or clinical research from NCI that enables multiple automatically coded self-administered 24-hour recalls and food records.
Diet History Questionnaire (DHQ)
A free food frequency questionnaire (FFQ) developed by NCI staff for use by researchers, clinicians, or teachers.
Healthy Eating Index (HEI)
The HEI is a measure of diet quality, independent of quantity, that can be used to assess compliance with the US Dietary Guidelines for Americans and monitor changes in dietary patterns.
Metabolic Equivalent of Task (MET) Values
This webpage provides the MET values for activities in the American Time Use Survey (ATUS) and the 2002 Census Occupational Classification System (OCS).
Keep up to date about the current Risk Factor Assessment projects and initiatives ongoing at EGRP.
Dietary Patterns Methods Project
This Project compared key diet quality indices and their associations with cancer and cardiovascular disease mortality. It was initiated to strengthen the scientific evidence base on dietary patterns and inform the 2015 Dietary Guidelines for Americans.

Interactive Diet and Activity Tracking in AARP (IDATA)
The purpose of the Interactive Diet and Activity Tracking in AARP (IDATA) study was to evaluate and compare the measurement error structure of diet and physical activity assessment tools against reference biomarkers. IDATA data and/or biospecimens are available as public use data, but researchers must submit a project proposal, which are reviewed by NCI.
Observing Protein and Energy Nutrition (OPEN) Study
The OPEN Study was an NCI-sponsored study 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. The study was conducted from July 1999 to March 2000 and included 484 men and women, aged 40-69 years old, living in Montgomery County, Maryland.
