Lack Of Agreement Between Polysomnography And Accelerometry Devices For Measuring Sleep Efficiency And Movement In University Students
MEASUREMENT IN PHYSICAL EDUCATION AND EXERCISE SCIENCE(2020)
摘要
The aim of the study was to determine the convergent validity of a portable polysomnograph and an accelerometer for measuring sleep efficiency and movement in college students. Volunteers were 29 healthy students (males = 15, females = 14) who simultaneously wore the Nox T3 portable polysomnograph and the ActiGraph wGT3X-BT accelerometer. Both devices recordedx, y, andzcoordinates at 10 Hz starting at 20:00:00 until the following morning. Repeated measures, concordance correlation coefficient, graphical, mixed-model, and Bayesian approaches were used to determine convergent validity. The sleep efficiency recorded by the Nox T3 was lower than the recorded by the ActiGraph wGT3X-BT (73.9 +/- 24.3% vs. 86.1 +/- 9.8%,p= .024; 95%CI = 1.8, 22.7), and both devices showed a poor concordance correlation coefficient (-0.09, 95%CI = -0.29, 0.13). The sleep monitor devices should not be used interchangeably to determine sleep efficiency and movement in college students.
