In January 2011, Statistics Canada published two papers from the Canadian Health Measures Survey (CHMS) which profiled the physical activity levels of Canadian adults and children, measured by accelerometer. These publications were preceded by publications relating to quality control, data reduction and analytical procedures for these data.

Despite detailed methodology in the physical activity papers, a background paper on data reduction and analytical procedures, several methodological papers on physical activity intensity cut-points, and a data user guide, there is still a gap in the information available to researchers who want to analyze their own Actical data in a way that is harmonized with the CHMS. The purpose of Accel+ is to provide the annotated SAS code required to convert raw count and step data from the Actical accelerometer into physical activity and sedentary behaviour derived variables. Intermediate knowledge of SAS is recommended.
