The Nutrition and Physical Activity Assessment Study (NPAAS) focuses on the use of objective biomarkers of dietary intake and physical activity and their use in regression calibration models to understand better the relationship between diet, physical activity and chronic disease risk in postmenopausal women. Our work in this area has been expansive and supports that there is systematic measurement error of self-reported diet and physical activity. The biomarker calibrated measures that correct for this systematic error are providing robust associations of risk for many cancers, cardiovascular disease and diabetes that are typically not apparent with uncorrected self-report.
