Abstract

There is a need to examine the difference in the relationship between oxygen uptake (VO2) and output from hip- and wrist-worn accelerometers in adults with Down syndrome (DS). The purpose of this study is to identify if that relationship is different between adults with and without DS. Hip- and wrist-worn accelerometer accuracy was also assessed. The sample included 16 adults with DS (10 men; age 31±15 years) and 19 adults without DS (10 men; age 24±6 years). We measured VO2 with a portable spirometer and accelerometer output (Vector Magnitude [VM]) with a hip- and a wrist-worn accelerometer. VM and group were significant predictors of VO2 (p?0.021). BMI became a significant predictor in the second model and DS was no longer significant for both accelerometer models. The Bland-Altman plots indicated nearly zero mean error for both groups. Hip-worn accelerometers showed greater accuracy, and showed less error based on 95% confidence intervals.
