The present study was conducted to clarify the prevalence of non-pharmacological self-management (nPSM) practices for obtaining good sleep and to identify favorable nPSM practices that could be applied for reducing excessive daytime sleepiness (EDS). We analyzed epidemiological data for an authentic representative sample of the Japanese population.
Data obtained from 24,686 adults via a self-administered questionnaire completed in the Active Survey of Health and Welfare 2000 were used for analyses. The prevalence of individual nPSM practices was calculated by gender. Subsequently, the associations between such practices and EDS were examined using logistic regression analyses.
"Having a bath" was the most prevalent nPSM practice for both men (59.0%) and women (64.4%), followed by "maintaining a regular schedule" (men: 49.0%, women: 58.6%), "reading or listening to music" (men: 43.4%, women: 49.4%), "snacking on food and/or beverages" (men: 36.1%, women: 27.9%), and "exercising" (men: 26.2%, women: 29.4%). The prevalence of "maintaining a regular schedule" increased with age. Multiple logistic regression analyses revealed that having a bath and maintaining a regular schedule had negative associations with EDS, whereas snacking on food and/or beverages had a positive association.
Having a bath and maintaining a regular schedule were identified as favorable nPSM practices for reducing EDS, whereas snacking on food and/or beverages was considered to be an unfavorable nPSM practice.

    ABSTRACT: To describe the different methods that older adults use to treat sleep problems and the perceived effectiveness of these methods. Cross-sectional study of treatment patterns for sleep disorders using a mailed questionnaire that gathered information concerning sleep history, demographics, and treatment choices. Community. Community-based sample of adults aged 65 and older, of whom 242 responded (67% response rate). Standardized questionnaires to assess sleep parameters (Pittsburgh Sleep Quality Index), demographic information, and sleep treatment options. Study participants engaged in a variety of treatment regimens to improve their sleep, with the average number of treatments attempted being 4.8±2.9. The most commonly used interventions were watching television or listening to the radio (66.4%) and reading (56.2%). The most commonly used pharmacotherapy was pain medication (40.1%). Prescription sleeping pills had the greatest self-reported effectiveness. Approximately half of all study participants who used alcohol or over-the-counter sleep aids had not discussed their sleep problems with their doctor. Older adults frequently choose treatments for their sleep problems that can potentially worsen their sleep symptoms. Many patients have not spoken to their healthcare provider about their treatment choices. These findings highlight the importance of discussing sleep habits and self-treatment choices, as well as treating sleep disorders, in older adults.

    ABSTRACT: The purpose of this study was to examine the correlation of sleepiness during night shift (SNS) in male shiftworkers with nonpharmacological self-management (nPSM) practices to facilitate good day sleep, and also with job stress. Sleepiness on the job and possible correlates to SNS among 157 male shiftworkers in a rotating three-shift schedule at a chemical plant were cross-sectionally investigated using a self-administered questionnaire. Multivariate analyses revealed that SNS was positively associated with drinking alcoholic beverages before day sleep, but inversely associated with subjective health status, being of the evening type, abstaining from caffeine before day sleep, having a bath before day sleep, job control, reward from work, feeling suited to the job, and support from colleagues. SNS correlated with certain nPSM practices and also with possible modifiers of job stress. These findings provide clues to developing countermeasures against SNS among shiftworkers. The effects of nPSM practices and job stress management on their day sleep and SNS should be examined in detail.

    ABSTRACT: There has been a lot of international research on morning/evening preference, but relatively little has been done in mainland China. This study investigated whether the trend for increased morning preference in older adults, which has been a consistent finding in chronotype research in many countries, is also found in Chinese. Using the Chinese translation of the Morningness–Eveningness Questionnaire (MEQ), it was found that a sample of 305 Beijing residents, aged 18–87, showed a significant correlation between MEQ score and age (r = 0.595), and that participants aged 50+ showed significantly more morning preference compared to younger participants. Additionally, a reliability assessment of the 5-question reduced MEQ (rMEQ) was undertaken. Test–retest assessment, involving a separate sample (n= 114), showed significant correlations between rMEQ and MEQ scores (r = 0.768), and between chronotype classifications (r = 0.524), supporting the reliability of the Chinese rMEQ.
