<P>PROBLEM TO BE SOLVED: To provide a sleep system and a sleep assessment apparatus for accurately assessing the quality of sleep. <P>SOLUTION: Sleep evaluation scores are obtained by main component analyses on a plurality of kinds of predetermined attributes including at least an attribute related to depth of sleep, an attribute related to rhythm of sleep, and an attribute related to middle awakening, extracted based on PSG measuring data. Main component coefficients on respective predetermined attributes of the sleep assessment scores are multiplied by sleep determining data corresponding to the predetermined attributes calculated from the living body signals of an object to be tested, to calculate sleep assessment scores. A logistic regression analysis is performed on the sleep assessment scores to calculate and obtain a sleep disorder discrimination probability. Based on the sleep disorder discrimination probability, the sleep assessment system and the sleep assessment apparatus calculate the sleep coefficient of the object to be tested. <P>COPYRIGHT: (C)2013,JPO&INPIT |
