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.

    ABSTRACT: The present study examined the effects of regularizing sleep–wake schedules on sleep, autonomic function and mood/emotional and personality states in 14 habitually irregular sleepers. During the experiment, sleep monitoring and regularized sleep–wake schedules were conducted at home. First, the subjects' habitual sleep–wake patterns were strictly monitored for 6 days (Session 1); second, subjects' irregular sleep–wake patterns were regularized for 6 days (Session 2); and finally, subjects reverted from their regularized sleep–wake schedules to their original, habitual sleep–wake schedules and were monitored for 6 days (Session 3). Assessments in the laboratory, which were conducted in the daytime, were repeated four times. The first three assessments were carried out on the days following Sessions 1, 2, and 3. The fourth measurement (Session 4), which was conducted under the original irregular sleep–wake pattern condition, was performed approximately 6 months after initiation of the second irregular sleep–wake schedule. In results, significant reductions in daytime parasympathetic activity and negative mood, i.e. tension–anxiety, anger–hostility, and fatigue, were observed after the 6‐day regularized sleep–wake schedule and extending through Session 3. However, the parasympathetic activity, as well as negative mood manifestations, returned to their initial levels when measured 6 months later. On the other hand, sleep and personality states did not change in response to alternations in sleep–wake regularity. However, the reduction of daytime fatigue level suggests a possibility that further sleep improvements might be difficult to detect under the regularized sleep–wake schedule because the subjects were healthy university students without sleep disorders.

    ABSTRACT: The association between sleep and work-related injuries among Chinese farmers has not been well studied. This study examined the impact of lack of sleep on agricultural work-related injuries among farmers in China. Data were from a cross-sectional survey of farm-workers in northeastern China. Information was obtained on injuries that occurred in 12 months prior to the survey, on eight sleep-related variables, and on socio-demographic variables. Logistic regression analyses were conducted to test the hypothesis that lack of sleep significantly increased the risk of work-related injuries after controlling for other injury-related risk- factors. Farmers who slept less than six hours per night were 59% more likely to be injured than those who slept more than eight hours per night (OR = 1.59; 95% CI = 1.04, 2.41). The odds of a work-related injury was 2.46 (1.56-3.89) for farmers who reported going to sleep after midnight at least once a week compared with farmers who reported going to sleep after midnight once a month. Farmers who reported having difficulty falling asleep or waking frequently during the night, who often having nightmares, or who experienced daytime sleepiness were at higher injury risk compared with the reference group after controlling for age, gender and alcohol consumption. Reduced sleep hours and poor sleep quality significantly increased the risk of work-related injuries in Chinese farmers. Sleep hours and sleep quality should be considered when assessing occupational safety among farmers.
