Description

Three sets of cut-points for classifying physical activity intensity from Euclidean Norm Minus One (ENMO) were generated using receiver operating characteristics (ROC) analysis for children wearing an ActiGraph on the right hip and each wrist. Sensitivity and specificity ranged from 27.4 to 82.6% and 50.1 to 96.1%, respectively.

Development/Validation

Sample: 32 children, 5-7 y of age

Setting: Inside and outside of school

Activities: Playground free-play, overground walking/running, sports/exercise, stationary

Criterion: Direct observation and compendium

Accelerometer(s): ActiGraph GT9X on right hip, each wrist

Validation approach: Holdout of 10 participants

Phase Designation

(What's this?)

This model is in Phase 2.
