Assessment Of Physical Activity And Sedentary Behavior Using Wearable Sensors: Measurement Considerations And Clinical Applications, Amanda Hickey

Doctoral Dissertations

The aims of study one of this dissertation were two-fold: 1) To understand the variability of sedentary behavior (SB) throughout a seven-day measurement period and 2) To determine the number of days of SB measurement required to reliably estimate seven-days of measurement. To address these aims, we utilized activPAL (AP) data from two existing data sets from the Physical Activity (PA) and Health Laboratory. Data were from 62 adults and 34 adolescents who had seven consecutive days of valid monitor wear. We found that adults were more sedentary on weekdays compared to weekend days, but there were no differences by …
