Abstract: Measuring physical activity reliably and accurately is challenging. The gold standard is limited because it is resource intensive. Accelerometer data has been used as a more accessible option but other less explored data such as time diary data could be a good alternative. Understanding how estimates differ by measurement strategy, including time diary data and accelerometer data, is thus an important contribution to the limited research base about physical activity measurement. Using nationally representative data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) and the 2006-2008 American Time Use Survey (ATUS), we investigate the following questions. First, how do recall estimates of time spent in physical activity in the ATUS compare to NHANES estimates based on accelerometer data? And, to what extent do these estimates vary by demographic characteristics?
