ABSTRACT OBJECTIVE: To measure the prevalence of sleep problems in a working population and examine their association with health problems, health-related
quality-of-life measures, work-related problems, and medical expenditures. Also, to explore the usefulness of a sleep-problems
screen for mental health conditions and underlying sleep disorders.

DESIGN: Cross-sectional survey administered via voice mail and telephone interview.

SETTING: A San Francisco Bay Area telecommunications firm.

PARTICIPANTS: Volunteer sample of 588 employees who worked for a minimum of six months at the company and were enrolled in its fee-for-service
health plan.

MEASUREMENTS AND MAIN RESULTS: Thirty percent of respondents reported currently experiencing sleep problems and were found to have worse functioning and
well-being (general health, cognitive functioning, energy), more work-related problems (decreased job performance and lower
satisfaction, increased absenteeism), and a greater likelihood of comorbid physical and mental health conditions than were
the respondents who did not have sleep problems. They also demonstrated a trend toward higher medical expenditures.

CONCLUSIONS: Self-perceived sleep problems were common among the respondents and were associated with poorer health and health-related
quality of life. A single question about sleep problems may serve as an effective screen for identifying primary care patients
with mental health problems, as well as underlying sleep disorders.

    • "As a central part of recovery, sleep quality is said to be important in preventing long-term negative effects of stress on health. Poor sleep quality, including fragmented sleep (increased amount of awakenings), inefficient sleep (reduced percentage of time spent sleeping) and increased sleep onset latency (increased time needed to fall asleep), has been associated with a variety of negative consequences, including health impairments such as elevated risk of myocardial infarction, coronary heart disease, muscle pain, headaches and gastrointestinal problems (Kuppermann et al., 1995; Schwartz et al., 1999). The causes of low sleep quality are various; however, evidence is increasing that work stress may play an important role in the development of disturbed sleep quality. "

    ABSTRACT: The present study investigated short-term effects of daily social exclusion at work on various indicators of sleep quality and tested the mediating role of work-related worries using a time-based diary study with ambulatory assessments of sleep quality. Ninety full-time employees participated in a 2-week data collection. Multilevel analyses revealed that daily workplace social exclusion and work-related worries were positively related to sleep fragmentation in the following night. Daily social exclusion, however, was unrelated to sleep onset latency, sleep efficiency and self-reported sleep quality. Moreover, worries did not mediate the effect of social exclusion at work on sleep fragmentation. Theoretical and practical implications of the results are discussed.

    • "Insomnia definitions ranged from too vague to too narrow. Several studies provided no symptom severity, frequency, or duration criteria (Kapur et al., 2002; Kuppermann et al., 1995), only symptom severity criteria (Hatoum, Kania, Kong, Wong, & Mendelson, 1998), or only symptom duration criteria (Weyerer & Dilling, 1991). Other studies used an operational definition of insomnia that was too restrictive (Leger et al., 2002; Novak et al., 2004; Simon & VonKorff, 1997). "

    ABSTRACT: Chronic insomnia is prevalent, contributes a significant economic burden, and people with insomnia have increased health care utilization (HCU). The purpose of this study was to investigate the relationship between chronic insomnia and HCU in a population with fewer medical/mental health problems, using current operational definitions of chronic insomnia and multiple measures of HCU. Participants with chronic insomnia had greater HCU than normal sleepers. Participants with chronic insomnia plus a comorbid condition had greater HCU than normal sleepers with a medical/mental health problem and participants with only chronic insomnia. The relationship between chronic insomnia and HCU was moderated by comorbid medical/mental health problems. Early identification and intervention of chronic insomnia may help reduce HCU and costs associated with chronic insomnia.

    • "In Korea, the prevalence of sleep problems ranges between 5.0 and 32.9 % (Cho et al. 2009; Kim et al. 2011; Nomura et al. 2010; Ohayon and Hong 2002), depending on the characteristics of the population sampled and the definition/case assessment. Sleep problems including insomnia, daytime sleepiness, and sleep apnea have been linked to a variety of occupational health issues; those employees with sleep problems reported an elevated risk of depression and anxiety disorders (Motohashi and Takano 1995; Nakata 2011b), alcohol abuse (Weissman et al. 1997), suicide (Goldstein et al. 2008) and chronic pain (Kuppermann et al. 1995) and are considered to be at high risk for hypertension (Murata et al. 2007; Yang et al. 2006) and coronary heart disease (Mallon et al. 2002).

    ABSTRACT: Purpose The purpose of this study was to assess the association of organizational factors with work-related sleep problems (WRSP) among Korean workers. Methods The data were derived from the First Korean Working Conditions Survey conducted in 2006 with a representative sample of the Korean working population (n = 10,039). Results The overall prevalence of WRSP was 5.1 % (95 % confidence interval (CI) 4.7–5.5). Those who experienced sexual harassment at work (adjusted odds ratio (aOR) 3.47: 95 % CI 1.77–6.81), discrimination due to sex (aOR 2.44: 95 % CI 1.36–4.36) or age (aOR 2.22: 95 % CI 1.52–3.23), violence at work (aOR 1.98: 95 % CI 1.06–3.68), threat of violence (aOR 1.96: 95 % CI 1.05–3.66), poor work-life balance (aOR 1.78: 95 % CI 1.44–2.20), low job satisfaction (aOR 1.69: 95 % CI 1.37–2.09), high cognitive (OR 1.64: 95 % CI 1.32–2.03) and emotional (aOR 1.53: 95 % CI 1.22–1.91) demands, job insecurity (aOR 1.32: 95 % CI 1.07–1.63), and high work intensity (aOR 1.55: 95 % CI: 95 % CI 1.25–1.92) had an increased risk of WRSP compared to their respective counterparts (p < 0.01). Low social support was not significantly associated with WRSP (aOR 0.88: 95 % CI 0.67–1.15). Conclusion The results revealed that poor psychosocial working conditions may be related to a high prevalence of WRSP among representative Korean workers.
