Objective Assessment of Physical Activity in Adults with Down Syndrome
Curtis, Jasmine Symone
The purpose of this study was to examine whether cut-points developed for the general population provide different estimates of physical activity (PA) levels in adults with Down syndrome (DS) compared to cut-points developed specifically in adults with DS. This study also attempted to objectively measure the PA levels of adults with DS and to determine if they meet the recommended amount of PA to obtain health benefits. Thirteen adults with DS wore an accelerometer to determine time spent in moderate, vigorous, and moderate-to-vigorous PA. Results indicated that different sets of cut-points responded differently in classifying moderate and vigorous PA levels, as well as in classifying whether participants met the recommended amount of PA for health benefits, as evidenced by the different estimates of moderate-to-vigorous PA in 10 minute bouts. Results also indicated that population specific cut-points should be used for assessment of PA levels in persons with DS.
