Abstract
BACKGROUND People with poor health or mental conditions are generally unwilling to participate in the health examinations, and no studies have directly examined the relationship of psychological distress among disaster survivors with participation status to date. The present study thus examined psychosocial differences according to the respondent status in a 5-year follow-up survey among participants in the prospective health surveys on survivors of the Great East Japan Earthquake and Tsunami Disaster study in Iwate Prefecture, Japan. METHODS We analyzed data from 10,203 Japanese survivors aged ≥18 years (mean age, 65.6 years; 38.0% men) and who underwent health examinations at baseline in 2011. Participants were classified into responders and nonresponders according to their 2015 health examination participation status. Psychological distress was evaluated using the Kessler 6 scale and categorized as none, mild, and severe. Multinominal logistic regression was used to examine the risk of psychological distress in relation to participation status. RESULTS In the 2015 survey, 6,334 of 6,492 responders and 1,686 of 3,356 nonresponders were analyzed. The most common reasons for nonparticipation in the survey were participated in other health examinations, examined at a hospital, and did not have time to participate. Nonresponse in males was associated only with mild psychological stress, whereas nonresponse in females was associated with mild and severe psychological distress. CONCLUSION Nonresponders in the follow-up survey had a higher risk of psychological distress than responders. Continuous monitoring of the health of nonresponders and responders may help to prevent future health deterioration.

Timing is everything: Circadian rhythms and their role in the control of sleep. Front Neuroendocrinol 2022; 66:100978. [PMID: 35033557 DOI: 10.1016/j.yfrne.2022.100978] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 12/12/2021] [Accepted: 01/08/2022] [Indexed: 01/16/2023]
Abstract
Sleep and the circadian clock are intertwined and have persisted throughout history. The suprachiasmatic nucleus (SCN) orchestrates sleep by controlling circadian (Process C) and homeostatic (Process S) activities. As a "hand" on the endogenous circadian clock, melatonin is critical for sleep regulation. Light serves as a cue for sleep/wake control by activating retino-recipient cells in the SCN and subsequently suppressing melatonin. Clock genes are the molecular timekeepers that keep the 24 h cycle in place. Two main sleep and behavioural disorder diagnostic manuals have now officially recognised the importance of these processes for human health and well-being. The body's ability to respond to daily demands with the least amount of effort is maximised by carefully timing and integrating all components of sleep and waking. In the brain, the organization of timing is essential for optimal brain physiology.

Abstract
Insomnia is very prevalent in psychiatry and is considered a transdiagnostic symptom of mental disorders. Yet, it is not only a consequence of a mental condition but may also exert detrimental effects on psychiatric symptom severity and therapeutic response; thus, adequate insomnia treatment is particularly important in psychiatric populations. The first choice of intervention is cognitive behavioral therapy for insomnia (CBT-I) as it is rather effective, also in the long run without side effects. It is offered in various forms, ranging from in-person therapy to internet-delivered applications. CBT-I protocols are typically developed for individuals with insomnia disorder without co-occurring conditions. For an optimal therapeutic outcome of CBT-I in individuals with comorbid mental disorders, adaptations of the protocol to tailor the treatment might be beneficial. Based on a literature search using major search engines (Embase; Medline; APA Psych Info; and Cochrane Reviews), this paper provides an overview of the effectiveness of the different CBT-I applications in individuals with diverse comorbid mental conditions and older adults and describes the functionality of CBT-I protocols that have been personalized to specific psychiatric populations, such as depression, substance abuse, and schizophrenia spectrum disorder. Finally, we discuss urgent needs for insomnia therapy targeted to improve both sleep and psychopathologies.

Socio-Ecological Context of Sleep: Gender Differences and Couples' Relationships as Exemplars. Curr Psychiatry Rep 2022; 24:831-840. [PMID: 36401678 PMCID: PMC9676909 DOI: 10.1007/s11920-022-01393-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/28/2022] [Indexed: 11/21/2022]
Abstract
PURPOSE OF REVIEW We summarized recent findings on insufficient sleep and insomnia, two prominent sleep issues that impact public health. We demonstrate the socio-ecologial impact of sleep health with findings on gender and couples' relationships as exemplars. RECENT FINDINGS Robust gender differences in sleep duration and insomnia are due to biological and socio-ecological factors. Gender differences in insufficient sleep vary by country of origin and age whereas gender differences in insomnia reflect minoritized identities (e.g., sexual, gender). Co-sleeping with a partner is associated with longer sleep and more awakenings. Gender differences and couples' sleep were affected by intersecting social and societal influences, which supports a socio-ecological approach to sleep. Recent and seminal contributions to sleep health highlight the importance of observing individual sleep outcomes in a socio-ecological context. Novel methodology, such as global measures of sleep health, can inform efforts to improve sleep and, ultimately, public health.

Relationship between insomnia with alcohol drinking before sleep (Ne-Zake) or in the morning (Mukae-Zake) among Japanese farmers. Alcohol 2021; 93:57-62. [PMID: 33745986 DOI: 10.1016/j.alcohol.2020.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 11/10/2020] [Accepted: 11/27/2020] [Indexed: 10/21/2022]
Abstract
BACKGROUND Ne-Zake is the drinking of alcohol before sleeping for helping to fall asleep and sleep well, and Mukae-Zake is the drinking of alcohol in the morning for "calming down" or "curing hangovers". OBJECTIVE We sought to examine the relationship of insomnia with Ne-Zake and Mukae-Zake among healthy middle-aged Japanese farmers. METHODS In a cross-sectional study of 746 participants (mean age, 59.5 years; women, 25.9%), Ne-Zake and Mukae-Zake were defined based on a self-administered questionnaire. Insomnia was defined as the Athens Insomnia Scale Japanese version ≥6 or usage of sleeping pills in the previous year. Logistic regression was used to calculate odds ratio (OR) of insomnia related to Ne-Zake and Mukae-Zake adjusting for sex, age, presence of sleep-related disorders, frequency of alcohol consumption, and quantity of alcohol consumed per one occasion. RESULTS We observed insomnia, Ne-Zake, and Mukae-Zake in 174 (23.3%), 140 (18.8%), and 37 (5.0%) participants, respectively. After adjustment for demographic and confounding factors, participants with Ne-Zake had a significantly higher prevalence of insomnia (OR 2.00 [95% confidence interval, 1.27-3.16]), compared to those without Ne-Zake. Mukae-Zake was also independently associated with a higher prevalence of insomnia among men (OR 3.26 [1.55-6.87]). Participants with both Ne-Zake and Mukae-Zake had a highly significant association with insomnia (OR 4.77 [2.01-11.3]) than those with neither Ne-Zake nor Mukae-Zake. Additionally, for insomnia, the association of Mukae-Zake was more pronounced than that of Ne-Zake (OR 4.09, 95% CI 1.14-14.7, p = 0.031; and OR 1.81, 95% CI 1.08-3.06, p = 0.026, respectively). CONCLUSION Ne-Zake and Mukae-Zake were associated with insomnia independent of the quantity and frequency of alcohol consumption among Japanese farmers. This finding can be used for stratifying individuals with insomnia not only to improve sleep hygiene but also to prevent alcohol dependence by informing the general population that alcohol has a negative effect on sleep, contrary to popular beliefs.

Age and gender differences in objective sleep properties using large-scale body acceleration data in a Japanese population. Sci Rep 2021; 11:9970. [PMID: 33976280 PMCID: PMC8113448 DOI: 10.1038/s41598-021-89341-x] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 04/26/2021] [Indexed: 11/11/2022] Open
Abstract
Using large-scale objective sleep data derived from body acceleration signals of 68,604 Japanese residents ranging from adolescents to the elderly (10–89 years old), we found significant age- and gender-related differences in sleep properties (timing, duration, and quality) in real-life settings. Time-in-bed and total sleep time (TST) showed a U-shaped association with age, indicating their decrease in adulthood following their increase in the elderly. There was a remarkable shift in sleep phase toward earlier bedtime and earlier wake time with increasing age (> 20 years), together with worsening of sleep quality, which is estimated by sleep efficiency (SE) and wake time after sleep onset. Gender comparisons showed that TST was shorter in women than in similarly aged men, which is much evident after the age of 30 years. This was associated with later bedtimes and greater age-related deterioration of sleep quality in women. Compared to men in the same age group, women over age 50 demonstrated a greater reduction in SE with aging, due mainly to increasing durations of nighttime awakening. These differences can be attributed to several intricately intertwined causes, including biological aging as well as socio-cultural and socio-familial factors in Japan. In conclusion, our findings provide valuable insights on the characteristics of Japanese sleep habits.

Gender differences in the prevalence and clinical correlates of sleep disturbance in general hospital outpatients. Psychiatry Res 2018; 269:134-139. [PMID: 30145295 DOI: 10.1016/j.psychres.2018.08.043] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2017] [Revised: 06/24/2018] [Accepted: 08/13/2018] [Indexed: 11/26/2022]
Abstract
This study investigated gender differences in the prevalence of sleep disturbance and related demographic and clinical characteristics, including quality of life (QOL), in Chinese outpatients. Up to 4399 adult outpatients (2896 females, 1503 males) who visited the neurological, cardiovascular, gastrointestinal, and gynaecological outpatient clinics in four general hospitals were recruited. Demographic and clinical data including QOL were collected by using self-report questionnaires. The prevalence of sleep disturbance in female outpatients (671/2896, 23.2%) was significantly higher than in male outpatients (302/1503, 20.1%) and remained significant after adjusting for significant confounders in the regression analysis. In the regression analysis, divorced/widowed and unemployed status were independently associated with a higher frequency of sleep disturbance in females, while educational level was independently associated with males only. Among these factors, depressive symptoms and older age were the most common risk factors for sleep disturbance in both genders. Sleep disturbance was not associated with the mental domains of the QOL assessments in both genders. This study suggests that sleep disturbance is more frequent in female outpatients and is associated with multiple factors in both genders. A longitudinal study is warranted to confirm the current findings.

Abstract
BACKGROUND Data on the prevalence of insomnia symptoms in medical outpatient clinics in China are lacking. This study examined the prevalence of insomnia symptoms and their socio-demographic correlates in patients treated at medical outpatient clinics affiliated with four general hospitals in Guangzhou, a large metropolis in southern China. METHOD A total of 4399 patients were consecutively invited to participate in the study. Data on insomnia and its socio-demographic correlates were collected with standardized questionnaires. RESULTS The prevalence of any type of insomnia symptoms was 22.1% (95% confidence interval (CI): 20.9-23.3%); the prevalence of difficulty initiating sleep was 14.3%, difficulty maintaining sleep was 16.2%, and early morning awakening was 12.4%. Only 17.5% of the patients suffering from insomnia received sleeping pills. Multiple logistic regression analysis revealed that male gender, education level, rural residence, and being unemployed or retired were negatively associated with insomnia symptoms, while lacking health insurance, older age and more severe depressive symptoms were positively associated with insomnia symptoms. CONCLUSIONS Insomnia symptoms are common in patients attending medical outpatient clinics in Guangzhou. Increasing awareness of sleep hygiene measures, regular screening and psychosocial and pharmacological interventions for insomnia are needed in China. TRIAL REGISTRATION ChiCTR-INR-16008066 .

Abstract
BACKGROUND Insomnia disorder is a subjective condition of unsatisfactory sleep (e.g. sleep onset, maintenance, early waking, impairment of daytime functioning). Insomnia disorder impairs quality of life and is associated with an increased risk of physical and mental health problems including anxiety, depression, drug and alcohol abuse, and increased health service use. hypnotic medications (e.g. benzodiazepines and 'Z' drugs) are licensed for sleep promotion, but can induce tolerance and dependence, although many people remain on long-term treatment. Antidepressant use for insomnia is widespread, but none is licensed for insomnia and the evidence for their efficacy is unclear. This use of unlicensed medications may be driven by concern over longer-term use of hypnotics and the limited availability of psychological treatments. OBJECTIVES To assess the effectiveness, safety and tolerability of antidepressants for insomnia in adults. SEARCH METHODS This review incorporated the results of searches to July 2015 conducted on electronic bibliographic databases: the Cochrane Central Register of Controlled Trials (CENTRAL, 2015, Issue 6), MEDLINE (1950 to 2015), Embase (1980 to 2015) and PsycINFO (1806 to 2015). We updated the searches to December 2017, but these results have not yet been incorporated into the review. SELECTION CRITERIA Randomised controlled trials (RCTs) of adults (aged 18 years or older) with a primary diagnosis of insomnia and all participant types including people with comorbidities. Any antidepressant as monotherapy at any dose whether compared with placebo, other medications for insomnia (e.g. benzodiazepines and 'Z' drugs), a different antidepressant, waiting list control or treatment as usual. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for eligibility and extracted data using a data extraction form. A third review author resolved disagreements on inclusion or data extraction. MAIN RESULTS The search identified 23 RCTs (2806 participants).Selective serotonin reuptake inhibitors (SSRIs) compared with placebo: three studies (135 participants) compared SSRIs with placebo. Combining results was not possible. Two paroxetine studies showed significant improvements in subjective sleep measures at six (60 participants, P = 0.03) and 12 weeks (27 participants, P < 0.001). There was no difference in the fluoxetine study (low quality evidence).There were either no adverse events or they were not reported (very low quality evidence).Tricyclic antidepressants (TCA) compared with placebo: six studies (812 participants) compared TCA with placebo; five used doxepin and one used trimipramine. We found no studies of amitriptyline. Four studies (518 participants) could be pooled, showing a moderate improvement in subjective sleep quality over placebo (standardised mean difference (SMD) -0.39, 95% confidence interval (CI) -0.56 to -0.21) (moderate quality evidence). Moderate quality evidence suggested that TCAs possibly improved sleep efficiency (mean difference (MD) 6.29 percentage points, 95% CI 3.17 to 9.41; 4 studies; 510 participants) and increased sleep time (MD 22.88 minutes, 95% CI 13.17 to 32.59; 4 studies; 510 participants). There may have been little or no impact on sleep latency (MD -4.27 minutes, 95% CI -9.01 to 0.48; 4 studies; 510 participants).There may have been little or no difference in adverse events between TCAs and placebo (risk ratio (RR) 1.02, 95% CI 0.86 to 1.21; 6 studies; 812 participants) (low quality evidence).'Other' antidepressants with placebo: eight studies compared other antidepressants with placebo (one used mianserin and seven used trazodone). Three studies (370 participants) of trazodone could be pooled, indicating a moderate improvement in subjective sleep outcomes over placebo (SMD -0.34, 95% CI -0.66 to -0.02). Two studies of trazodone measured polysomnography and found little or no difference in sleep efficiency (MD 1.38 percentage points, 95% CI -2.87 to 5.63; 169 participants) (low quality evidence).There was low quality evidence from two studies of more adverse effects with trazodone than placebo (i.e. morning grogginess, increased dry mouth and thirst). AUTHORS' CONCLUSIONS We identified relatively few, mostly small studies with short-term follow-up and design limitations. The effects of SSRIs compared with placebo are uncertain with too few studies to draw clear conclusions. There may be a small improvement in sleep quality with short-term use of low-dose doxepin and trazodone compared with placebo. The tolerability and safety of antidepressants for insomnia is uncertain due to limited reporting of adverse events. There was no evidence for amitriptyline (despite common use in clinical practice) or for long-term antidepressant use for insomnia. High-quality trials of antidepressants for insomnia are needed.

Abstract
PURPOSE To clarify the prevalence and symptomatic characteristics of sleep disturbance/insomnia among type-2 diabetes mellitus (DM) Japanese patients. METHODS A cross-sectional survey of Japanese patients with the disorder was conducted. Participants consisted of 622 type-2 DM patients (mean 56.1±9.56 years) and 622 sex- and age-matched controls. Participants' scores in the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J), the Japanese version of the 12-item Center for Epidemiologic Studies Depression Scale (CES-D), the Medical Outcomes Study 8-item Short Form Health Survey (SF-8), and the glycated hemoglobin A1c (HbA1c) of type-2 DM patients were analyzed. RESULTS There were 253 poor sleepers (43.9%) in the type-2 DM group as a result of dichotomization with the PSQI-J cutoff total score of 5.5. The type-2 DM group recorded a higher mean PSQI-J total score (P<0.01) and manifested poorer sleep maintenance. Poor sleepers in both groups had lower mental component summary from SF-8 (MCS), physical component summary from SF-8 (PCS), and CES-D than good sleepers, and good sleepers in both groups had higher MCS, PCS, and CES-D than poor sleepers. Higher body mass index, presence of smoking habit, and living alone were significantly associated with sleep disturbance/insomnia symptoms, but HbA1c was not associated with sleep disturbance/insomnia in the type-2 DM group. CONCLUSION Individuals affected with type-2 DM are likely to experience sleep problems, characterized by disturbance in sleep maintenance. Sleep disturbance/insomnia symptoms in DM patients might considerably reduce health-related quality of life.

Abstract
Introduction Sleep disorders are the cause of morbidity and mortality and can decrease functional capacity and quality of life. Nurses, especially those working irregular or night shifts, are at risk for developing sleep disorders. The present study aims to determine the relationship between sleep quality and health-related quality of life (HRQOL) as well as quantitative and subjective aspects of sleep quality in nurses. Methods This cross-sectional study was conducted on 1456 nurses working in 11 hospitals in Shiraz and Tehran (Iran) in 2014. Structured questionnaires (Pittsburg Sleep Quality Index [PSQI] and Medical Outcomes Study Short Form-36 Survey [SF-36]) were used to collect data on participants’ demographic characteristics, sleep quality, and health-related quality of life. Chi-square and independent samples t-test were employed for statistical analysis. Results Mean age of participants was 30.81 ± 7.8, and most of them were female (89.04%) and poor sleepers. Long-duration sleepers slept for more than 9.8 h/night, and they obtained higher scores than short-duration sleepers (<4.5 h/night) in all SF-36 domains. The study results showed that increased quality of life was significantly related to health-related quality of life. Conclusions This study showed strong evidence that sleep disorders, such as poor quality and short duration of sleep, are negatively associated with HRQOL. Therefore, developing systemic strategies to cope with the problem seems to be necessary.

Abstract
Primary sleep disorders include those not attributable to another medical or psychiatric condition: insomnia disorder, hypersomnolence disorder, narcolepsy, obstructive sleep apnea hypopnea syndrome, central sleep apnea syndrome, and the parasomnias. They are commonly encountered and are comorbid with many psychiatric disorders. It is important to recognize these disorders and be comfortable treating them or to know when to refer to a sleep disorders center and sleep specialist. Treatment of a comorbid sleep disorder can improve the overall quality of life, symptoms in mood disorders, and symptoms of excessive daytime sleepiness, and decrease cardiovascular morbidity and mortality.

Abstract
The poor sleep quality is one of the major risk factors of somatic, psychiatric and social disorders and conditions as well as the major predictors of quality of employees' performance. The previous studies in Iran had neglected the impacts of social factors including social networks and ties on adults sleep quality. Thus, the aim of the current research was to determine the relationship between social networks and adult employees' sleep quality. This study was conducted with a correlational and descriptive design. Data were collected from 360 participants (183 males and 177 females) who were employed in Yazd public organizations in June and July of 2014. These samples were selected based on random sampling method. In addition, the measuring tools were the Pittsburgh Sleep Quality Index (PSQI) and Social Relations Inventory (SRI). Based on the results, the prevalence rate of sleep disorder among Iranian adult employees was 63.1% (total PSQI>5). And, after controlling for socio-demographic variables, there was significant difference between individuals with strong and poor social network and ties in terms of overall sleep quality (p<.01), subjective sleep quality (p<.01), habitual sleep efficiency (p<.05), and daytime dysfunction (p<.01). The results also revealed that the employees with strong social network and ties had better overall sleep quality, had the most habitual sleep efficiency, and less daytime dysfunction than employees with poor social network and ties. It can be implied that the weak social network and ties serve as a risk factor for sleep disorders or poor sleep quality for adult employees. Therefore, the social and behavioral interventions seem essential to improve the adult's quality sleep.

Abstract
STUDY OBJECTIVES Despite several polysomnographic normative studies and multiple surveys of sleep disorders in the general population, few data have been collected on healthy sleepers. We aimed to survey the characteristics of healthy sleep. METHODS We prospectively investigated the sleep history of 100 subjects of a representative population sample who reported undisturbed sleep and in whom relevant sleep disorders were ruled out by a two-step screening procedure. Approximately four subjects had to be contacted for identifying 1 eligible subject who participated. RESULTS The median reported time in bed was from 23:00 (21:30-02:00) to 07:00 (05:30-11:00). The total sleep duration was 7.3 h (5-10 h), varying from 7.5 h in the age group ≤ 30 years to 7 h in subjects aged 40-60 years and to 8 h in subjects > 60 years (p = 0.002). The median sleep efficiency was high (93.3%, range: 55.6% to 100%). Fifty-one subjects reported occasional snoring. Forty-five subjects reported sporadic non-bothersome sleep-related movement disorders (25 sleep-related leg cramps, 22 lifetime bruxism, 5 restless legs syndrome), and 36 had a history of sporadic non-bothersome parasomnias (27 nightmares, 12 sleepwalking, 1 sleep paralysis). CONCLUSION In this population of healthy sleepers, snoring is the most common finding. Moreover, non-bothersome forms of recognizable sleep-related movement disorders and parasomnias are surprisingly common. These findings may suggest that diagnostic criteria of sleep disorders should not only be based on the presence of symptoms but also account for a minimum frequency or discomfort.

Abstract
STUDY OBJECTIVES GABA is increasingly recognized as an important neurotransmitter for the initiation and maintenance of sleep. We sought to measure cortical GABA content through proton magnetic resonance spectroscopy (MRS) in persons with and without primary insomnia, and relate brain GABA levels to polysomnographic sleep measures. DESIGN Two-group comparison study. SETTING Outpatient study at a university research clinic. PARTICIPANTS Non-medicated persons with primary insomnia (N = 16) and no sleep complaints (N = 17). INTERVENTIONS Participants kept sleep diaries and a regular time-in-bed schedule for 9 days, culminating in 2 consecutive nights of ambulatory polysomnography and a single proton MRS session. The main outcome measure was occipital GABA/creatine ratios; secondary measures included sleep measurements and relationship between polysomnographically measured time awake after sleep onset and occipital GABA content. MEASUREMENTS AND RESULTS The primary insomnia group was distinguished from persons with no sleep complaints on self-reported and polysomnographically measured sleep. The two groups did not differ in age, sex, body mass index, habitual bed- and wake-times, napping, use of caffeine, or use of cigarettes. Mean occipital GABA level was 12% higher in persons with insomnia than in persons without sleep complaints (P < 0.05). In both groups, GABA levels correlated negatively with polysomnographically measured time awake after sleep onset (P < 0.05). CONCLUSIONS Increased GABA levels in persons with insomnia may reflect an allostatic response to chronic hyperarousal. The preserved, negative relationship between GABA and time awake after sleep onset supports this notion, indicating that the possible allostatic response is adaptive.

Abstract
Sleep disorders are common in the general population and even more so in clinical practice, yet are relatively poorly understood by doctors and other health care practitioners. These British Association for Psychopharmacology guidelines are designed to address this problem by providing an accessible up-to-date and evidence-based outline of the major issues, especially those relating to reliable diagnosis and appropriate treatment. A consensus meeting was held in London in May 2009. Those invited to attend included BAP members, representative clinicians with a strong interest in sleep disorders and recognized experts and advocates in the field, including a representative from mainland Europe and the USA. Presenters were asked to provide a review of the literature and identification of the standard of evidence in their area, with an emphasis on meta-analyses, systematic reviews and randomized controlled trials where available, plus updates on current clinical practice. Each presentation was followed by discussion, aimed to reach consensus where the evidence and/or clinical experience was considered adequate or otherwise to flag the area as a direction for future research. A draft of the proceedings was then circulated to all participants for comment. Key subsequent publications were added by the writer and speakers at draft stage. All comments were incorporated as far as possible in the final document, which represents the views of all participants although the authors take final responsibility for the document.

Abstract
PRIMARY OBJECTIVE To investigate the impact of disorders of arousal and sleep disturbance on everyday living and participation in rehabilitation. RESEARCH DESIGN Survey of rehabilitation centres based on naturalistic observation. METHOD One hundred and thirty-five adults with acquired brain injury were reported by rehabilitation staff in seven centres across the UK for presence of arousal and/or sleep disturbance, the impact on rehabilitation and daily living and treatment strategies in use. OUTCOMES Disturbance of arousal or sleep patterns was reported in 47% of the sample, with significant adverse effect on activity evident in two-thirds of such cases. Prevalence of disordered arousal was consistent over time for up to 10 years post-injury. Concurrent psychiatric illness, but not epilepsy, was associated with arousal and sleep disorder. Non-pharmacological interventions and benzodiazepine/hypnotic drugs were in use in 34% and 20% of cases respectively. In all cases of prescribed hypnotic drugs, period of use exceeded recommended UK guidelines. CONCLUSIONS Long-term outcome from severe brain injury can be compromised by enduring disturbance of arousal, most commonly evidenced as sleep disorder. Treatment should be based on judicious use of medication (beyond hypnotic drugs) and greater emphasis on non-pharmacological management.

Abstract
Insomnia is a common complaint in breast cancer patients and has been shown to have a host of psychological and medical correlates and consequences. Typically insomnia is treated pharmacologically, however more recent findings from randomized controlled clinical trials support the use of cognitive behavioral therapies. The aim of this article is to review the empirically supported breast cancer literature on insomnia, briefly present and explain the insomnia treatment options available, and extrapolate research guidelines for future directions in this growing field. Behavioral therapeutic approaches for insomnia seem particularly suitable to use in the breast cancer populations because they have lower risk of interacting with the cancer treatment, do not burden the patients with additional pharmacological treatments, and can target the treatment towards ameliorating specific symptoms, like fatigue, that are characteristic in this population. However, there is a need for replication of efficacy studies of cognitive behavioral treatments for insomnia in breast cancer, as well as studies investigating vulnerability, risk and protective factors that might ultimately lead to insomnia prevention programs for use in this population.

Abstract
UNLABELLED Patients with chronic somatoform pain often complain about sleep disorders. However, sleep disorder/disturbances are not an integrated part of the somatoform disorders in the DSM-IV and the ICD-10. Sleep is important for recreation. Deprivation of deep sleep stages is experimentally linked to muscle pain. Therefore, sleep disorder may play an important part in the persistence of somatoform pain disorder. The aim of the study was to evaluate the frequency of sleep disorder in patients with somatoform pain disorder and to correlate it with comorbid depression, pain parameters and psychosocial parameters. METHOD In this study, 147 patients (mean age: 48.8 years; SD: 11.0) with the diagnosis of a somatoform pain disorder were studied with regard to affective comorbidity, pain duration (months), maximum pain within the last month, minimum pain within the last month and medium pain within the last month, psychosocial disability within the last month and the presence of a sleep disorder. RESULTS Eighty-four percent of the patients had a sleep disorder. The patients with a sleep disorder had significantly higher maximum and medium pain, a significantly higher level of psychosocial disability and a significantly lower overall subjective well-being. The medium pain and psychosocial disability in leisure and social activities are significant predictors for sleep disorder. CONCLUSIONS The presence of a sleep disorder may be a hint for higher pain intensity and a higher level of psychosocial disability. Sleep disorder may be a factor in the persistence and aggravation of pain as well as psychosocial disability. Therefore, sleep disorder should be integrated in the therapeutic targets. It is suggested that sleep disorder should be a diagnostic criterion in somatoform pain disorder.

Abstract
Sixty percent of 536 new referrals to a psychiatric clinic at a general hospital complained of insomnia. Prevalence was high in all psychiatric categories, especially in physiologic disorders, somatoform disorders and mood disorders, followed by epilepsy. Complaints of difficulty in falling asleep were high in the physiologic and somatoform disorder groups. Complaints of nocturnal awakening were high in the anxiety and physiologic disorder groups, while complaints of early morning awakening were high in the organic and mood disorder groups. Prescription rates of hypnotics was most prevalent in the mood and adjustment disorder groups, whereas a non-pharmacological approach, including psychological education and behavioral therapy, was applied mainly to the physiologic disorder group.

Abstract
The aim of this study was to evaluate the influence of somatic health, mental health and age on sleep and the use of sleep medication in a group of elderly men and women. Questionnaires were distributed to 9417 persons, and the response rate was 69%. The mean ages (s.d.) of the male and female participants were 73.9 (6.3) and 74.5 (6.8) years, respectively. Sleep disturbances were more common in women than in men at all ages and increased with age in both sexes. A stepwise regression analysis showed that in men, more severely sleep disturbances were associated with poorer somatic health (R(2)=0.089; P<0.0001), poorer mental health (R(2)=0.106; P<0.0001) and increasing age (R(2)=0.109; P<0.0001) and in the women worse somatic health (R(2)=0.087; P<0.0001), worse mental health (R(2)=0.104; P<0.0001) but no further deterioration of sleep with age. Sleep medication was more common in women than in men at all ages and increased with age in both sexes. The use of sleep medication was more strongly related to somatic health than to mental health and age in both sexes. In conclusion, both sleep complaints and sleep medication showed a stronger relation to somatic health than to mental health and age in this group of elderly men and women.

Abstract
In order to investigate the occurrence and history of sleep problems in Japan, the 11-Centre Collaborative Study on Sleep Problems (COSP) project was carried out. Complaints of snoring are examined, and its prevalence, risk factors and screening reliability are discussed. The subjects who participated in the study were 6445 new outpatients from a general hospital. They were asked to answer a sleep questionnaire that consisted of 34 items with seven demographic items; each item was composed of four grades of frequency. In order to offset possible seasonal variations in sleep habits, data were collected across four seasons. Sleep patterns, insomnia, hypersomnia, parasomnia and circadian rhythm sleep disorders were covered. Habitual snoring was seen in 16.0% of males and 6.5% of females. Male predominance was noted. From these data, the relationship between habitual snoring and sleep complaints was statistically analyzed. Habitual snorers (HS) were observed to wake up more frequently during sleep (17.8% of males, 21.5% of females) than were non-habitual snorers (NHS; 6.6% of males, 9.7% of females). Mid-sleep awakening of HS was also more frequent than it was for NHS; however, there were no differences in difficulty in falling asleep and early morning awakening. Body mass index, cigarette smoking and alcohol consumption were also correlated with habitual snoring.
