“…If the symptom of difficulty maintaining sleep was the defining factor, 11.5% of the sample was affected. However, using the more stringent criteria from DSM-IV, 5% of the sample qualified for the diagnosis (Ohayon & Hong, 2002). Similar disparities were shown in a prevalence study from France (Leger et al, 2000).…”

“…1 In recent years, a number of studies have indicated that sleep duration may be an important indicator of one's perceived health status. [2][3][4][5][6][7][8][9][10][11][12][13] Several studies also indicate that disorders of sleep duration hamper both perceived physical and mental health 4,5,9,[14][15][16] and report that perceived health risks in individuals with sleep durations are somewhat greater than those in individuals with chronic physical illness. 8,10 Moreover, both short and long sleep duration are associated with elevated risk of diabetes mellitus, hypertension, and cardiovascular disease (CVD).…”

Study Objectives: Sleep duration is recognized as one of the most common issues in modern society. Self-rated health is a commonly used subjective health measure based on a single question asking individuals to rate their general health on a four-or fi ve-point scale. However, few studies have examined the relationship between sleep duration and self-rated health. Here, we examined the association between sleep duration and poor self-rated health, using a large representative sample of the general Korean adult population. Design: We conducted a cross-sectional study of 15,252 participants in the Korea National Health and Nutrition Examination Survey IV (2007)(2008)(2009)) who were aged 19 years and older. Sleep duration was categorized as ≤ 5, 6, 7, 8, or ≥ 9 hours. The main outcome of interest was poor self-rated health (n = 3,705, 19.7%). Multiple logistic regression analysis was performed to examine the association between sleep duration and self-rated health. Results: We found both short (≤ 5 h) and long (≥ 9 h) sleep duration to be associated with poor self-rated health independent of sociodemographic, health risk, and health status variables. Compared with 7-h sleep duration, the multivariate odds of poor self-rated health were 1.358 times higher (95% CI 1.167-1.580) with short sleep duration and 1.322 times higher (95% CI 1.091-1.601) with long sleep duration. This association persisted in subgroup analyses of gender, body mass index, and age by gender. Conclusions:In a large representative sample of the Korean general adult population, compared with sleep duration of 7 hours, we found a positive association between short and long sleep duration and poor self-rated health in Korean adults. Furthermore, the association between sleep duration and poor self-rated health was consistently present in subgroups divided by gender, age, and BMI.

“…A consistent finding in literature is the higher prevalence of insomnia among women than in men (Breslau et al, 1996;Léger et al, 2000;Sutton et al, 2002;Ohayon, 2002;Ohayon & Partinen, 2002;Ohayon & Hong, 2002), there being few studies that observed higher prevalence in men (Kim et al, 2000).…”

“…Insomniacs tend to be unhappier in interpersonal relationships and have a relatively low self-esteem, having inadequate coping mechanisms to deal with stress (Ohayon & Hong, 2002;Basta et al, 2007). However, in the majority of cases, primary insomnia (aetiology that is not related to another mental disorder, medical condition or substance dependence) may be induced by a stress situation, such as: withdrawal of a family member, sadness, loss or stress at work, economic difficulty, surgical intervention, etc, that would occupy the individual's mind while trying to sleep (LeBlanc et al, 2009;Kim et al, 2011).…”
