“…In the present study, the percentage of individuals who had suicidal ideation was higher among stroke survivors who slept <5 h, but lower among stroke survivors who slept ≥9 h. Such results point to the importance of stroke survivors receiving adequate sleep duration. Even after adjusting for significant covariates, the final model confirmed that stroke survivors who slept ≤5 h were 2.71‐fold more at risk of suicidal ideation than those who slept ≥9 h. This result is consistent with previous studies of the general adult population, adolescents and college students . Because suicidal ideation is more common among stroke survivors than the general adult population, our analysis of sleep duration and suicidal ideation among stroke survivors is highly meaningful.…”

Aim Many stroke survivors experience sleep disorders, and are at risk of severe depression and stress. This study examined the association between mental health and sleep duration among Korean stroke survivors. Methods This cross‐sectional study analyzed data from the Korea National Health and Nutrition Examination Surveys V (2010–2012) and VI (2013). The nationally representative sample included 504 adults aged ≥19 years. Results The odds ratio for suicidal ideation was 2.71 (95% confidence interval 1.11–6.60) for stroke survivors who slept <5 h as compared with stroke survivors who slept between 6 and 8 h. Although stress and depression did not differ according to sleep duration, suicidal ideation did. Conclusions Sleep duration should be considered as a possible leverage point for preventing suicidal ideation among stroke survivors, and health promotion programs that promote and educate survivors about the importance of appropriate sleep duration are required.

“…The average working time of adult Korean women is 217 min per day, whereas American women work an average of 179 min per day, and German women work an average of 124 min per day. 31 These findings indicate that Korean adults work longer hours than adults in comparable nations and are therefore more likely to be sleep deprived.…”

Study Objectives: Sleep can affect quality of life (QOL). We examined the association between self-reported sleep time and QOL independent of perceived health status and depressive disorder using the EuroQol-5 Dimension (EQ-5D) and a visual analog scale (VAS). Methods: We used the nationwide cross-sectional survey data of 28,178 subjects from the Korea National Health and Nutrition Examination Survey (KNHANES) IV-V. Self-reported sleep time was assessed by average hours of sleep per day. QOL was measured using the EQ-5D and VAS. A generalized additive model and multiple linear regression analysis were used to estimate the effect of sleep time on the QOL while adjusting for potential confounding variables. Results: We found a signifi cant inverted U-shaped relationship between sleep time and QOL using both the EQ-5D and VAS indices. Compared with subjects who slept 7 h/day, Korean men whose sleep time was very short (≤ 4 h/ day) or very long (≥ 10 h/day) had substantially worse QOL (−3.125 in EQ-5D, p < 0.001 and −4.387 on the VAS, p = 0.000 for ≤ 4 h/day; −1.763 in EQ-5D, p = 0.001 and −1.944 on the VAS for ≥ 10 h/day, all p = 0.038). A similar inverted U-shape was observed between sleep time and QOL in Korean women. Conclusions: Inappropriate sleep time (either short or long) in both men and women was signifi cantly associated with lower QOL. In particular, such an association was more apparent among persons whose perceived health status was poor.

Association between Total Sleep Duration and Suicidal Ideation among the Korean General Adult Population

Abstract: The sleep duration/suicidal ideation relationship is U-shaped in the Korean adult population. Self-reported habitual sleep duration may be a useful behavioral indicator for both individual and societal suicidal ideation risk.
