Validation of the Phillips et al GENEActiv accelerometer wrist cut-points in children aged 5-8 years old

This study examined the accuracy of the Phillips et al. GENEActiv accelerometer wrist worn cut-points in children aged 5-8. Fifteen children (6 girls, 9 boys) aged 5-8 years wore a GENEActiv monitor on their non-dominant wrist while undertaking 5 minute bouts of lying supine, playing Lego, walking at slow, medium and fast pace and running. Receiver Operating Curve (ROC) analysis was employed to establish how well the Phillips et al (2013) cut points classified intensity of the activities compared to the actual intensity determined by indirect calorimetry. Area Under the Curve (AUC) values were high for sedentary (.970), moderate (.815) and vigorous (.974) activity. Conclusion: The Phillips et al (2013) cut-points for the GENEActiv accelerometer can be used in children aged 5-8 years old to distinguish sedentary behaviour, moderate and vigorous PA behaviour.
