Mathematica Policy Research Reports from Mathematica Policy Research

Abstract: This working paper used measurements of accelerometer-based and self-reported physical activity from the National Health and Nutrition Examination Survey 2003–2006 to develop and validate a set of models for predicting objective moderate to vigorous physical activity from self-report variables and other demographic characteristics.
