To investigate the effects of shift work schedules on sleep quality and mental health in female nurses in south Taiwan.
This study recruited 1,360 female registered nurses in the Kaohsiung area for the first survey, and among them, 769 nurses had a rotation shift schedule. Among the 769 rotation shift work nurses, 407 completed another second survey 6-10 months later. Data collection included demographic variables, work status, shift work schedule, sleep quality (Pittsburgh Sleep Quality Index), and mental health (Chinese Health Questionnaire-12).
Nurses on rotation shift had the poor sleep quality and mental health compared to nurses on day shift. The nurses on rotation shift had a relatively higher OR of reporting poor sleep quality and poor mental health (OR, 2.26; 95% CI, 1.57-3.28; and OR, 1.91; 95% CI, 1.39-2.63, respectively). Additionally, rotation shift nurses who had ≥2 days off after their most recent night shifts showed significantly improved sleep quality and mental health (PSQI decreased of 1.23 and CHQ-12 decreased of 0.86, respectively). Comparison of sleep quality between the first and second surveys showed aggravated sleep quality only in nurses who had an increased frequency of night shifts.
Female nurses who have a rotation shift work schedule tend to experience poor sleep quality and mental health, but their sleep quality and mental health improve if they have ≥2 days off after their most recent night shifts. This empirical information is useful for optimizing work schedules for nurses.

    ABSTRACT: Workers who meet the criteria for shift work disorder (SWD) have elevated levels of risk for various health and behavioral problems. However, the impact of having SWD on shiftworkers engaged in rapid-rotation schedules is unknown. Moreover, the risk factors for the occurrence of SWD remain unclear. To clarify these issues, we conducted a questionnaire-based, cross-sectional survey on a sample of shiftworking nurses. Responses were obtained from 1202 nurses working at university hospitals in Tokyo, Japan, including 727 two-shift workers and 315 three-shift workers. The questionnaire included items relevant to age, gender, family structure, work environment, health-related quality of life (QOL), diurnal type, depressive symptoms, and SWD. Participants who reported insomnia and/or excessive sleepiness for at least 1 mo that was subjectively relevant to their shiftwork schedules were categorized as having SWD. The prevalence of SWD in the sampled shiftworking nurses was 24.4%; shiftworking nurses with SWD showed lower health-related QOL and more severe depressive symptoms, with greater rates of both actual accidents/errors and near misses, than those without SWD. The results of logistic regression analyses showed that more time spent working at night, frequent missing of nap opportunities during night work, and having an eveningness-oriented chronotype were significantly associated with SWD. The present study indicated that SWD might be associated with reduced health-related QOL and decreased work performance in shiftworking nurses on rapid-rotation schedules. The results also suggested that missing napping opportunities during night work, long nighttime working hours, and the delay of circadian rhythms are associated with the occurrence of SWD among shiftworking nurses on rapid-rotation schedules.

    ABSTRACT: Purpose of the study: The stigma of being dangerous, socially incompetent and useless has been carried by the mentally ill for centuries. The issue seems even more serious when the fact that psychiatric disorders are estimated to account for 12% of the global burden of disease is taken into account. Today stigma may affect more than one in every ten of people on the planet. The aim of the study was to analyze the attitudes of young people towards the mentally disordered and to find what factors are determining these attitudes. Methods used: A specially designed questionnaire was posted on one of the websites particularly popular amongst young users. The questionnaire was composed of 12 questions and consisted of two parts, one of which was concerned with demographic data (re- spondents’ age, gender and place of residence), while the other − with the respondents’ knowledge of different mental disorders and their views regarding the mentally ill. It contained mainly yes/no questions. The factual knowledge of mental disorders was checked using a list of 8 exemplary illnesses. The respondents were asked to tell if each of these 8 illnesses was or was not a mental disorder. A specially designed survey engine had a built-in cookie-based mechanism to avoid re-participation of the respondent. None of information such as IP addresses or browser type was gathered to make the survey highly anonymous. Results: 11,900 people were questioned, including 71% women. 30% of the interviewees were under the age of 19, while 34% of them were between 19 and 24 years old and 36% were over 24. 39% of the interviewees stated they closely knew at least one mentally ill person. 44% of the questioned believed a lot of criminal offenders were mentally ill. 66% of interviewees would not mind sharing a flat with a mentally disordered person, 64% would agree to work with one. Those who personally knew a mentally disordered person were more inclined to share a flat or start a relationship with such an individual, than the rest of the interviewed (51% vs. 37% for flat sharing and 38% vs. 26% for starting a relationship, p < 0.001). More questioned under the age of 19 believed that significant number of criminal offenders were mentally ill, than those over the age of 24 (50% vs. 37%, p < 0.001). Conclusions: Our study shows that many young Poles believe the mentally disordered are inclined to break the law and behave aggressively. These opinions seem to be related amongst others to age and gender, and they result in unwillingness to have relations with the mentally disordered. The better the knowledge of mental disorders and the mentally ill however, the more positive the attitude towards them, which shows that there is a great need for educational anti-stigma interventions. Appropriate programs should address the lack of factual information on the subject and popularize therapeutics advances in psychiatry in order to fight the regard of mental illnesses as incurable and permanently disabling.
