The participants were classified as normoestimators (estimation of TST <±60 minutes), underestimators (underestimation of TST ≥60 minutes), or overestimators (overestimation of TST ≥60 minutes). The standardized SF-36 QOL scores were compared among the three groups. An adjusted partial correlation analysis was conducted between SOD and QOL.<h4>Results</h4>Of the 2540 paPsychosomatic medicineAssociation Between Subjective-Objective Discrepancy of Sleeping Time and Health-Related Quality of Life: A Community-Based Polysomnographic Study.PMC9064942U01 HL063463U01 HL053931U01 HL053941U01 HL053934U01 HL053938U01 HL053916R24 HL114473U01 HL053937U01 HL064360Kang JMKo KPKang SGCho SELim WJRedline SWinkelman JWfalseAssociation Between Subjective-Objective Discrepancy of Sleeping Time and Health-Related Quality of Life: A Community-Based Polysomnographic Study.<h4>Objective</h4>This study aimed to investigate the existence of a difference in quality of life (QOL) between individuals with and without significant subjective-objective discrepancy (SOD) in total sleep time (TST).<h4>Methods</h4>From the Sleep Heart Health Study 2, 2540 individuals who had completed polysomnography, a morning sleep survey, and the 36-item Short-Form Health Survey (SF-36) were included in the analyses.
