Important Differences in Accelerometer Cut Points for Quantifying Physical Activity in a Nested Occupational Cohort

Abstract

Background: Accurate physical activity assessment is becoming increasingly important in epidemiologic research. There is an increasing body of evidence suggesting that physical activity can prevent or reduce severity of disease. Utilizing accelerometers as an objective quantification of physical activity is a cost effective way to assess physical activity, yet there is little research on the agreement between different proposed cut points in a free-living, healthy adult population.
