A consensus method for estimating physical activity levels in adults using accelerometry
Clevenger, 2022
Description
Demonstrates use of a "consensus method" whereby 10 methods for estimating time spent in moderate-to-vigorous physical activity are averaged. In this sample of adults wearing a hip-worn ActiGraph, mean absolute error was 4.2 min, compared to 4.9-12.3 min for individual classification methods.
Development/Validation
Sample: 30 (15 males) healthy adults, 18-79 years of age
Setting: Laboratory
Activities: Activities of daily living, cycling, walking and running, resistance exercise, stairs, stationary behaviors
Criterion: Activity type
Accelerometer(s): ActiGraph GT9X on right hip
Validation approach: Comparison to criterion
Instructions
Ten individual classification methods (below) are used to calculate time spent in moderate-to-vigorous physical activity, then averaged together as the "consensus estimate."
