Relationships of sleep duration with sociodemographic and health-related factors, psychiatric disorders and sleep disturbances in a community sample of Korean adults

Abstract

Summary The aim of this study is to examine relationships of sleep duration with sociodemographic and health‐related factors, psychiatric disorders and sleep disturbances in a nationwide sample in Korea. A total of 6510 subjects aged 18–64 years participated in this study. Logistic regression was used to calculate the odd ratios and 95% confidence intervals of the covariates, psychiatric disorders and sleep disturbances across the following sleep duration categories: 5 h or less, 6, 7, 8 and 9 h or more per day. Low levels of education, unemployment and physical illness were associated with sleeping for 5 h or less and 9 h or more. Being older and widowed/divorced/separated, high levels of physical activity, pain/discomfort, obesity and high scores on the General Health Questionnaires were associated with sleeping for 5 h or less. Female, being younger and underweight were associated with sleeping for 9 h or more. Alcohol dependence, anxiety disorder and social phobia were associated significantly with sleeping for 5 h or less and 9 h or more. Other psychiatric disorders were more common in subjects who slept for 5 h or less (e.g. alcohol use disorder, mood disorder, major depressive disorder, dysthymic disorder, obsessive‐compulsive disorder and specific phobia) or 9 h or more (e.g. post‐traumatic stress disorder). In addition, subjects who slept for 5 h or less reported more sleep disturbances than did subjects who slept for 7 h. Short or long sleep is associated with psychiatric disorders and/or sleep disturbance, therefore attention to the mental health of short or long sleepers is needed.

The relationship between sleep disturbance in late pregnancy and labor outcomes

“…This is not in agreement to what was reported by This current study has shown that there was a significant difference between Apgar scores of the babies at one minute after birth and the mothers' actual night sleep duration. There is also a highly significant difference between the baby's Apgar score of five minutes after birth (Park et al, 2010). In the present study, birth weight was related to labor outcomes; there was a highly significant difference between birth weight and duration of sleep at night.…”

Academic Performance among Adolescents with Behaviorally Induced Insufficient Sleep Syndrome

“…Although short sleep duration can be voluntarily induced as in BISS, sleep duration may also be shortened despite efforts to sleep as in adolescent insomnia or depression. 4,5 A "natural" short sleeper without BISS may sleep less without voluntary effort to curtail sleep. In addition, the correlation between subjective measurement of sleepiness as ESS and objective of sleepiness as multiple sleep latency test (MSLT) has been reported not to be as high as expected.…”

“…Adolescents experiencing insomnia 4 or depression 5,6 may be unable to get suffi cient sleep despite efforts to do. Because there are large individual variations in sleep need, a typically short sleeper can sleep less without sleep debt or sleepiness than ordinary people.…”

Mental Disorders in Subjects with Diabetes: A Systematic Review

“…Chronic diseases cause more than 50% of deaths worldwide [1,2]. Furthermore, it is estimated that deaths from chronic diseases will increase by 15% in the next 10 years [1][2][3][4].…”
