“…These differences between physical and mental QOL in their relationship to sleep duration are similar to those found in studies of the general population in the United Kingdom and United States [ 4 ]. Although the findings of this study suggest that the relationship between sleep duration and mental QOL is modest, considering the well-documented importance of sleep duration with respect to lower QOL [ 4 , 5 , 6 , 7 , 8 , 9 , 46 ], the health risks of habitual short sleep duration should still be emphasized.…”

“…The questionnaire in this study included demographic information regarding age, sex, height, weight, occupation, smoking status, habitual alcohol ingestion, and the presence/absence of currently treated diseases [ 8 , 25 ]. Because body mass index was not normally distributed as a continuous variable, we divided it into five groups: less than 18.5 kg/m 2 , 18.5 to less than 25 kg/m 2 , 25 to less than 30 kg/m 2 , 30 to less than 35 kg/m 2 , and 35 kg/m 2 or greater [ 26 ].…”

“…Both quantitative and qualitative aspects of subjective sleep evaluation are reported to affect QOL. Several cross-sectional reports have indicated that short sleep duration is associated with lower QOL in the general population [ 4 , 5 , 6 , 7 , 8 , 9 ]. Simultaneously, a number of cross-sectional studies in the general population have reported that poor sleep quality is also associated with lower QOL [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ].…”

This study aimed to determine whether both subjective sleep quality and sleep duration are directly associated with quality of life (QOL), as well as indirectly associated with QOL through insomnia symptoms. Individuals aged 20–69 years without mental illness (n = 9305) were enrolled in this web-based cross-sectional survey. The Short Form-8 was used to assess physical and mental QOL. We used the Pittsburgh Sleep Quality Index (PSQI) and extracted items related to subjective sleep quality and sleep duration. Insomnia symptoms were also extracted from the PSQI. The hypothesized models were tested using structural equation modeling. Worse sleep quality, but not shorter sleep duration, was related to worse physical QOL. Both worse sleep quality and shorter sleep duration were related to worse mental QOL. Insomnia symptoms mediated these relationships. Subgroup analyses revealed a U-shaped relationship between sleep duration and physical/mental QOL. However, the relationship between sleep quality and physical/mental QOL was consistent regardless of sleep duration. The results suggest that subjective sleep quality has a more coherent association with QOL than subjective sleep duration. Because of its high feasibility, a questionnaire on overall sleep quality could be a useful indicator in future epidemiological studies of strategies for improving QOL.

“…A U-shaped association was also observed between sleep duration and depressive score [9] and between sleep duration and the risk of type II diabetes [16]. For example, Kaneita et al [9] revealed that not only participants whose sleep duration was <6 h, but also those whose sleep duration was ≥8 h, tended to be more depressed than those whose sleep duration was 6-8 h. In addition, Matsui et al [17] showed that sleep disturbances, physical and mental quality of life (QOL), and depression scores were worse in both the shorter and longer sleep groups compared with the group with 7-8 h of sleep. However, previous reports have not distinguished people who slept for a short/long duration due to individual life schedules from genetically determined short/long sleepers or insomniacs.…”

Although sleep debt and social jetlag (SJL) influence daytime dysfunctions, the effects of both sleep debt and SJL on them have not been analyzed. The aim of this study was to examine the mutual relationship between sleep debt and SJL on daytime sleepiness, mood, and work performance. This study was a cross-sectional study on sleep health conducted on the Japanese general population. A total of 4505 general workers (30% female, aged 43.57 ± 11.63 years) were selected and analyzed. Sleep debt was defined by sleep debt index (SDI), which is the discrepancy between desired and real sleep duration. SJL and SDI scores exhibited a positive but weak coefficient (r = 0.19). In a 4 (SJL) × 3 (SDI) two-way ANOVA, the interaction effects were notable for sleepiness and depression scores, while the group effects were notable for the work performance score. For sleepiness and depression scores, SDI >2 h was not significantly different from SJL. In addition, the impact of SDI was higher than that of SJL on sleepiness (β = 0.17), depression (β = 0.16), and work performance (β = −0.10). The impact of sleep debt was more pronounced than SJL on daytime dysfunctions, although both sleep debt and SJL have negative impacts on them.
