Statistical methods for estimating relative intensity physical activity and its association with cardiometabolic disease

Using data from the CARDIA study, we will develop and validate statistical methods for objectively measuring relative intensity physical activity (PA) using accelerometry. Our specific aims are to: 1) Develop statistical methodology for calculating relative-intensity PA accelerometer cut-points and apply these methods to data from the CARDIA exercise treadmill test; and 2) Determine the relationship between relative-intensity PA and the development of cardiometabolic disease as compared to absolute-intensity PA.
