How is NCI supporting the NHANES?

We provided funds to the National Center for Health Statistics (NCHS) to support modules in the National Health and Nutrition Examination Survey (NHANES) that are critical to our risk factor monitoring mission. These modules included the Food Frequency Questionnaire (formerly called Food Propensity Questionnaire) and a wearable physical activity monitor both of which were incorporated in the NHANES from 2003 - 2006. The FFQ data can be used to help estimate usual dietary intakes, and the physical activity monitors provide a much-needed objective assessment of this important risk factor (see Physical Activity).

We also have worked with NCHS to develop a Web-based tutorial to encourage and support analyses of NHANES data.
