“…Additionally, previous studies have indicated that people with sleeping problems were predisposed to psychological disorders such as depression, anxiety disorder, and suicide attempts [46]. In our study, sleeping time was significantly associated with anxiety symptoms, but physicians with fewer than six hours of sleep per day had a tendency to experience depressive symptoms (P = 0.08) [47].…”

BackgroundPhysicians’ poor mental health not only hinders their professional performance and affects the quality of healthcare provided but also adversely affects patients’ health outcomes. Few studies in China have evaluated the mental health of physicians. The purposes of this study are to quantify Chinese physicians’ anxiety and depressive symptoms as well as evaluate associated risk factors.MethodsIn our study, 2641 physicians working in public hospitals in Shenzhen in southern China were recruited and interviewed by using a structured questionnaire along with validated scales testing anxiety and depressive symptoms. Multivariable logistic regression models were used to identify risk factors for anxiety and depressive symptoms.ResultsAn estimated 25.67% of physicians had anxiety symptoms, 28.13% had depressive symptoms, and 19.01% had both anxiety and depressive symptoms. More than 10% of the participants often experienced workplace violence and 63.17% sometimes encountered it. Among our study population, anxiety and depressive symptoms were associated with poor self-reported physical health, frequent workplace violence, lengthy working hours (more than 60 hours a week), frequent night shifts (twice or more per week), and lack of regular physical exercise.ConclusionsOur study demonstrates that anxiety and depressive symptoms are common among physicians in China, and the doctor-patient relationship issue is particularly stressful. Interventions implemented to minimize workload, improve doctor-patient relationships, and assist physicians in developing healthier lifestyles are essential to combat anxiety and depressive symptoms among physicians, which may improve their professional performance.

“…There was no significant association between depressive symptoms and length of sleeping time, which is one factor related to working conditions. It has been reported that work that allows highly independent control of working hours is associated with better sleep and health (Takahashi et al 2012). This agrees with the result of the present study that depression in discretionary workers was not related to working hours.…”

“…The focus on control of working hours as a job stress prevention measure is a result of studies on the relationship between occurrence of job stress and illness showing a link between incidence of illness and work styles, which leads to regulations controlling long working hours and discretion over control of working hours (Fujino et al 2006). Moreover, working long hours generally reduces the duration and quality of sleep and is linked to depressive symptoms (Yamasaki and Shimada 2009;Takahashi et al 2011Takahashi et al , 2012. The national labor administration in Japan thus proposed a number of recommended work styles that should be implemented by workplaces to control working hours as a component of health management (Ministry of Health, Labour and Welfare 2002).…”

In Japan, the number of workers with depressive symptoms has increased recently, and long working hours are considered one of the main contributing factors. Currently, the number of workers engaging in discretionary work is small but is expected to increase, as a diverse method of employment is believed to contribute to workers' well-being. However, the factors related to discretionary workers' depressive symptoms are unclear. This study aimed to identify the factors associated with depressive symptoms in discretionary workers. The subjects were 240 male discretionary workers in a Japanese insurance company. A cross-sectional study was performed using a questionnaire that includes demographic characteristics, living and working conditions, work-related and non-work-related stressful events, and the Center for Epidemiologic Studies Depression Scale (CES-D). Depressive symptoms were assessed as more than 16 points on the CES-D. Multiple logistic regression models were employed to estimate odd ratios (OR) with 95% confidence intervals (95% CI) of depressive symptoms in relation to possible factors. Thirty-six subjects (15.5%) showed depressive symptoms. The depressive symptoms were significantly related to age (p = 0.04), presence of child(ren) (p = 0.02), and length of employment (p = 0.01), but unrelated to working hours. Subjects who reported "financial matters" (OR = 4.50, 95% CI = 1.89-10.72) and "own event" such as divorce or illness (OR = 2.93, 95% CI = 1.13-7.61) were more likely to show depressive symptoms. In conclusion, mental health measures for discretionary workers should focus on addressing financial difficulties and consultations and assistance in personal health and family issues.

“…Control over working times may alleviate various work demands during working hours and subsequently facilitate recovery. Workers with increased work time control had lower levels of insomnia symptoms, fatigue and depression than workers with poor control over working times (Takahashi et al 2012). Moreover, poor working time control predicts sickness absence (Ala-Mursula et al 2002) and disability pensioning (Vahtera et al 2010).…”

Association of job strain with working hours, shift-dependent perceived workload, sleepiness and recovery

et al. 2013

We explored the relationship of job strain with working hours, shift-dependent perceived workload, sleepiness and recovery. Nurses/nursing assistants (n = 95) were recruited from wards that belonged to either the top (high-strain group, HJS) or the bottom (low-strain group, LJS) job strain quartiles of a Job Content Questionnaire survey of employees in five health care districts and four cities in Finland. Three-week field measurements during naturally occurring shift schedules and a subset of pre-selected shift arrangements consisted of the Karolinska Sleepiness Scale, perceived workload and recovery. The HJS group (n = 42) had more single days off and quick returns than the LJS group (n = 53, p < 0.01), and both mental workload and physical workload were rated as higher (p < 0.01). During naturally occurring shift arrangements, severe sleepiness was more common in the HJS group only in quick returns (p = 0.04) and the HJS group recovered on average more poorly from work after all shifts (p = 0.01) and morning shifts (p = 0.02). During pre-selected shift arrangements, the differences between the groups were only minor. In conclusion, job strain-related differences in sleepiness and recovery were mostly attributable to differences in shift arrangements.
