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.
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).
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.
This study has demonstrated that sleep problems have individual significance with regard to perceived physical or mental health status.
[Show abstract][Hide abstract] ABSTRACT: The authors assessed the subjective symptoms of temporomandibular disorders (TMDs) in 167 young patients using self-reported forms, with five ratings for pain intensity and six ratings for difficulty in activities of daily living (ADL), to compare TMD symptoms according to gender and three age groups: group 1: 6- to 12-year-olds (juvenile); group 2: 13- to 15-year-olds (early adolescent); group 3: 16- to 18-year-olds (late adolescent). No significant gender differences were found in the symptoms among the groups, except for headache and neck pain in group 3. Pain intensity and tightness in the jaw/face, headache, and neck pain, as well as the ADL-related difficulty in prolonged jaw opening, eating soft/hard foods, and sleeping significantly differed among the groups (p < 0.01, Kruskal-Wallis test). Therefore, late adolescent patients with TMDs have higher pain intensity in the orofacial region and greater difficulty in ADL than do early adolescent and juvenile patients with TMDs.

[Show abstract][Hide abstract] ABSTRACT: Previous studies have demonstrated that sleep-related problems are common in the aging process. Such problems are greater in nursing home residents than other elderly people. This study had the following objectives: (1) establish the clinical profile of nursing home residents according to their quality of sleep and intake of hypnotic medication, (2) assess participants' functionality in relation with their quality of sleep and (3) correlate participants' functional status with their quality of sleep. The study sample was composed of 334 nursing home residents. Results showed a high percentage (72.1%) of poor sleepers in nursing homes. We found significant differences (p<0.05) in functionality according to quality of sleep and a significant correlation (p<0.05) between the subscales of the Pittsburgh Sleep Quality Index (PSQI) and most subareas of the Functional Status Questionnaire (FSQ). The study showed the existence of a relationship between sleep quality and functional status in elderly people living in nursing homes. These results suggest that additional precautions should be taken when managing nursing home residents with sleep disturbances.

[Show abstract][Hide abstract] ABSTRACT: Schlafstörungen sind mit einer Vielzahl von körperlichen und psychischen Gesundheitsstörungen verbunden und verursachen hohe gesundheitsökonomische und volkswirtschaftliche Folgekosten. Ziel der hier vorliegenden Studie war es, die Häufigkeit und Verteilung von Ein- und Durchschlafstörungen, der Schlafqualität, der Schlafdauer, des Schlafmittelkonsums sowie des Insomniesyndroms in der deutschen Erwachsenenbevölkerung zu berichten. Etwa ein Drittel der Befragten hatte während der letzten 4 Wochen potenziell klinisch relevante Ein- oder Durchschlafstörungen, etwa ein Fünftel berichtete zusätzlich über eine schlechte Schlafqualität. Unter zusätzlicher Berücksichtigung von Tagesbeeinträchtigungen wie Müdigkeit und/oder Erschöpfung ergab sich eine Prävalenz von 5,7 % für ein Insomniesyndrom. Frauen waren doppelt so häufig von Insomnie betroffen wie Männer, signifikante Altersunterschiede gab es nicht. Personen mit niedrigem Sozialstatus (OR: 3,44) und Personen mit Wohnsitz in Westdeutschland (OR: 1,53) hatten ein erhöhtes Risiko für Insomnie, wobei Frauen mit niedrigem Sozialstatus (OR: 4,12) und westdeutsche Männer (OR: 1,79) stärker betroffen waren. Die Ergebnisse verdeutlichen die hohe Public-Health-Relevanz von Insomnie-bezogenen Schlafstörungen.
