“…More in detail, the prevalence rates of students dissatisfied with their sleep quality and those suffering from insomnia symptoms were 20.3% (95% CI 13.0-30.3) and 23.6% (95% CI 18.9-29.0), respectively. Subgroup analyses revealed that among the diverse student groups, the category of medical students was particularly prone to sleep-related disorders [50]. This is in line with our findings, showing higher rates among medical and nursing students and lower ones among paramedical students.…”

Medicine and healthcare professions are prestigious and valued careers and, at the same time, demanding, challenging, and arduous jobs. Medical and allied health professions students, experiencing a stressful academic and clinical workload, may suffer from sleep disturbances. In Iran, several studies have been conducted to explore the prevalence rate among medical and healthcare professions students. The aim of this systematic review and meta-analysis was to quantitatively and rigorously summarize the existing scholarly literature, providing the decision- and policy-makers and educators with an updated, evidence-based synthesis. Only studies utilizing a reliable psychometric instrument, such as the Pittsburgh sleep quality index (PSQI), were included, in order to have comparable measurements and estimates. Seventeen investigations were retained in the present systematic review and meta-analysis, totaling a sample of 3586 students. Studies were conducted between 2008 and 2018 and reported an overall rate of sleep disturbances of 58% (95% confidence interval or CI 45–70). No evidence of publication bias could be found, but formal analyses on determinants of sleep disturbances could not be run due to the dearth of information that could be extracted from studies. Poor sleep is highly prevalent among Iranian medical and healthcare professions students. Based on the limitations of the present study, high-quality investigations are urgently needed to better capture the determinants of poor sleep quality among medical and healthcare professions students, given the importance and the implications of such a topic.

“…Whether this discrepancy reflects the increase in DIMS we observed in Norwegian youth over this period is unclear. The rate is in addition higher than that (18.5%) reported in a systematic review of university students (Jiang et al., ), and also higher than the estimated prevalence rate of insomnia symptoms (23.6%) found in a meta‐analysis of Chinese university students (Li et al., ). The present study is restricted to assessing prevalence rates and does not inform on the causal factors accounting for the high rate of insomnia.…”

Summary The aim of this study was to describe sleep patterns and rate of insomnia according to diagnostic criteria in college and university students, as well as to examine potential changes in sleep problems from 2010 to 2018. Data stemmed from a national student health survey from 2018 for higher education in Norway (the SHoT study), which invited all 162,512 fulltime students in Norway. A total of 50,054 students (69.1% women) aged 18–35 years were included, yielding a response rate of 30.8%. Sleep parameters, reported separately for weekdays and weekends, included calculations of bedtime, rise time, sleep duration, sleep‐onset latency, wake after sleep onset, sleep need and sleep deficit. Insomnia was defined according to the Diagnostic and Statistical Manual of Mental Disorders (5th edn) criteria. For the trend analysis, we used one item measuring difficulties initiating and/or maintaining sleep, over three time points (2010, 2014 and 2018). The results from 2018 showed large weekday–weekend differences across most sleep parameters. Both male and female students obtained a mean sleep duration in the lower end of the normal range on weekdays (7:24 hr), but met their own sleep need and sleep recommendations at weekends (8:25 hr). The overall prevalence of insomnia was 34.2% in women and 22.2% in men. There was a substantial increase in sleep problems from 2010 (22.6%) to 2018 (30.5%), which was especially pronounced in women. We conclude that sleep problems are both prevalent and increasing among students. This warrants attention as a public health problem in this population.

“…However, the prevalence of insomnia and its associated factors are rarely known in steel workers, especially in China. Several socio-demographic, psychological, lifestyle-and be havior-related, as well as occupational factors are associated with insomnia, including anxiety, physical health, religious beliefs [5], sex [6], alcohol consumption [20], a lack of steady income, less frequent social contacts, reduced social capital, living alone [7], shift work [21], occupational stress [8], etc. However, little is known about whether the prevalence of insomnia and its associated factors are different across job categories of steel workers.…”

“…In previous studies [1][2][3][4], the prevalence of insomnia ranged 7.1-79.8% in general populations in the world, e.g., 7.1% in Norway [2], 22.1% in the USA [1], 11.9% in Hong Kong of China [3], and 79.8% in Brazil [4]. In China, studies have shown that the prevalence of insomnia ranges 12.7-55.7% in different populations [5][6][7][8]. Although the prevalence of insomnia varies considerably in terms of criteria and symp-toms, the prevalence above 30% for the global general population is commonly accepted.…”

This study aimed to investigate the prevalence of insomnia and risk factors among different job categories of steel workers in China, in order to improve their quality of occupational life. Material and Methods: A cross-sectional face-to-face survey was conducted which involved 5834 steel workers from a large enterprise located in northern China, including front-line, maintenance and inspection, and other auxiliary workers. The Athens Insomnia Scale and the Job Content Questionnaire were used to assess the status of insomnia and job stress/social support, respectively. Multivariable logistic regression was used to identify factors influencing insomnia. Results: The overall prevalence of insomnia was determined at 42.0% (95% confidence interval: 40.7%-43.2%). For front-line, maintenance and inspection, and other auxiliary workers, the prevalence was 42.3%, 39.8%, and 47.9% (p = 0.001), respectively. The participants with high stress and low support, and those who had experienced ≥2 major life events in the past 12 months, compared to those with low stress and high support, and those without major events, displayed an increased risk of insomnia among all 3 job categories (the adjusted odds ratio ranged 1.56-2.38 and 1.30-1.75, respectively). The educational level, shift work, alcohol consumption, and present illness were identified as influencing factors of insomnia for 1 or 2 job categories. Conclusions: The prevalence of insomnia was the highest in the group of other auxiliary steel workers among the 3 job categories of steel workers under consideration. While the influencing factors of insomnia differed among the groups, job stress and major life events were common risk factors of insomnia among the 3 categories of steel workers.
