RESUMO
This study aimed to investigate the association between insomnia symptoms and non-restorative sleep (NRS) in individuals with Typus melancholicus, a personality trait linked to depression, in the general population. We analyzed data from a Japanese cross-sectional survey of 2519 randomly sampled adults. Typus melancholicus was evaluated using a modified version of Kasahara's Typus melancholicus inventory (modified-KTM). Logistic regression analysis was used to examine the associations of insomnia symptoms and NRS with modified-KTM scores. We demonstrated that insomnia symptoms and NRS were both positively associated with modified-KTM scores. Our results provide evidence for an association between Typus melancholicus and insomnia.

BACKGROUND: The following question remains open: what has the strongest impact on symptoms of depression, experiencing multiple stressful events, being exposed to a specific stressful event, or having a maladaptive coping style? METHOD: We conducted a cross-sectional survey with face-to-face interviews. Data from 2559 randomly-sampled adults living in Japan were analyzed. The participants were asked about stressful events (12 items) experienced in the previous month and their stress-coping strategies (16 items). Presence of symptoms of depression was defined using the Center for Epidemiologic Studies Depression scale. Logistic regression analysis was used to assess the associations of stressful events and stress-coping strategies with symptoms of depression. RESULTS: The prevalence of symptoms of depression increased with the number of stressful events. Eight stressful events and five stress-coping strategies were positively associated with symptoms of depression. In the multiple logistic regression analysis for the items that showed a significant association with symptoms of depression, two stressful events ("Health/illness of self" and "Trouble with family members") and two stress-coping strategies ("Smoking" and "Bearing without action") remained significantly associated with symptoms of depression; however, the "dose effect" of the number of stressful events disappeared, suggesting that these stressful events and stress-coping strategies have a stronger association with symptoms of depression compared with experiencing multiple stressful events. LIMITATIONS: Since this study was cross-sectional in design, causal relationships could not be determined. CONCLUSION: Our findings may indicate the importance of focusing on types of stressful events and coping styles in developing preventive strategies for major depression.

OBJECTIVE: To investigate the relationship between unhealthy lifestyles factors and depressive symptoms among the general adult population in Japan. METHOD: Participants were randomly selected from the Japanese general adult population. Data from 2334 people aged 20 years or older were analyzed. This cross-sectional survey was conducted in August and September 2009. Participants completed a face-to-face interview about unhealthy lifestyle factors, including lack of exercise, skipping breakfast, a poorly balanced diet, snacking between meals, insufficient sleep, current smoking, alcohol drinking, and obesity. Presence of depressive symptoms was defined as a score of ≥â¯16 on the Japanese version of the Center for Epidemiologic Studies Depression Scale (CES-D). Relationships between unhealthy lifestyle factors and depressive symptoms were evaluated by multivariate logistic regression analysis adjusting for sociodemographic variables and other unhealthy lifestyle factors. RESULTS: Multivariate logistic regression analysis revealed that insufficient sleep, a poorly balanced diet, snacking between meals and lack of exercise were significantly associated with the prevalence of depressive symptoms, with odds ratios ranging from 1.56 for lack of exercise to 3.98 for insufficient sleep. LIMITATIONS: Since this study was a cross-sectional study, causal relationships could not be determined. CONCLUSION: These results suggest that promoting a healthy lifestyle focused on sleep, food intake and exercise may be important for individuals with depressive symptoms.

OBJECTIVE: Sleep problems in humans have been reported to impact seriously on daily function and to have a close association with well-being. To examine the effects of individual sleep problems on physical and mental health, we conducted a nationwide epidemiological survey and examined the associations between sleep problems and perceived health status. METHODS: Cross-sectional surveys with a face-to-face interview were conducted in August and September, 2009, as part of the Nihon University Sleep and Mental Health Epidemiology Project (NUSMEP). Data from 2559 people aged 20 years or older were analyzed (response rate 54.0%). Participants completed a questionnaire on perceived physical and mental health statuses, and sleep problems including the presence or absence of insomnia symptoms (i.e., difficulty initiating sleep [DIS], difficulty maintaining sleep [DMS], and early morning awakening [EMA]), excessive daytime sleepiness (EDS), poor sleep quality (PSQ), short sleep duration (SSD), and long sleep duration (LSD). RESULTS: The prevalence of DIS, DMS, and EMA was 14.9%, 26.6%, and 11.7%, respectively, and 32.7% of the sample reported at least one of them. At the complaint level, the prevalence of EDS, PSQ, SSD, and LSD was 1.4%, 21.7%, 4.0%, and 3.2%, respectively. Multiple logistic regression analyses revealed that DMS, PSQ, SSD, and LSD were independently associated with poor perceived physical health status; DIS, EDS, and PSQ were independently associated with poor perceived mental health status. CONCLUSIONS: This study has demonstrated that sleep problems have individual significance with regard to perceived physical or mental health status.

OBJECTIVE: The aim of this study was to examine the relationship between self-help behaviors for sleep (SHBS) and depression among the general adult population in Japan. METHODS: The survey was conducted in June 2000 using self-administered questionnaires for subjects living in 300 communities randomly selected throughout Japan. A total of 24,686 responses were analyzed from individuals aged 20 years or older. The Center for Epidemiologic Studies Depression Scale was used to assess the prevalence of depression with two cut-off points: 16 and 25. Details of 6 types of SHBS were asked, based on given examples of actual behavior and frequency. RESULTS: After adjusting for sociodemographic variables, sleep problems and other SHBS, multiple logistic regression analyses revealed that "snacking on food and/or beverages" was independently associated with an increased odds ratio for depression, whereas "maintaining lifestyle regularity" was independently associated with a decreased odds ratio for depression. "Drinking alcoholic beverages," "having a bath," and "reading books or listening to music" were associated with an increased odds ratio for depression in crude analyses, but the significance of the association disappeared after adjusting for sociodemographic variables, sleep problems and other SHBS. LIMITATION: Complex constructs are being correlated. CONCLUSIONS: These results suggest that individual SHBS are differentially associated with depression, thus providing important clues for establishing sleep hygiene for treatment and prevention of depression.

Most psychiatric disorders, such as schizophrenia, mood disorders, or neurotic disorders are associated with sleep disorders of various kinds, among which insomnia is most prevalent and important in psychiatric practice. Almost all patients suffering from major depression complain of insomnia. Pharmacological treatment of insomnia associated with major depression shortens the duration to achieve remission of depression. Insomnia has been recently reported to be a risk factor for depression. Hypersomnia is also a major sleep problem in patient suffering from depression. There have been no clinical guide to treat the symptoms of hypersomnia in depression, but some clinical trials treating them with NDRI or adjunctive administration of psychostimulants. In patients with schizophrenia, insomnia is often an early indicator of the aggravation of psychotic symptoms. Electroencephalographic sleep studies have also revealed sleep abnormalities characteristic to mood disorders, schizophrenia and anxiety disorders. A shortened REM sleep latency has been regarded as a biological marker of depression. Reduced amount of deep Non-REM sleep has been reported to be correlated with negative symptoms of schizophrenia. Recently, REM sleep abnormalities were found in teenagers having post-traumatic stress disorder after a boat accident. Although these facts indicate that insomnia plays an important role in the development of psychiatric disorders, there are few hypotheses explaining the cause and effect of insomnia in these disorders. Here, we reviewed recent articles on insomnia and hypersomnia associated with psychiatric disorders together with their clinical managements.
