Background: Although the 2000s observed enormous changes in China, little is known about the variation in the prevalence of mental disorders. The study compared the prevalence in a Chinese population between 2004 and 2015.Methods: Multistage stratified random sampling methods were used to identify primary sampling sites for cross-sectional surveys in 2004 and 2015 in Shandong, China. In 2004 and 2015, 22,718 and 28,194 adults, respectively, completed an expanded version of the General Health Questionnaire, then 5,402 and 9,420 adults, respectively, were administered a Chinese version of the Structured Clinical Interview for Diagnostic and Statistical Manual-IV axis I disorders.Results: The adjusted 1-month prevalence of any mental disorders was 18•7% (95% CI: 16•7-20•8) and 17•1% (95% CI:15•9-18•4) in 2004 and 2015, respectively. However, the prevalence of major depressive disorders increased from 1•5% (95% CI: 1•2 -1•8) in 2004 to 2•3% (95% CI: 1•9-2•8) in 2015; meanwhile the prevalence of alcohol abuse disorders were becoming more common among men and urban residents. Although mood and anxiety disorders were more prevalent in women, a much more prevalent alcohol abuse disorders for men contributed to a higher overall prevalence among men than among women. Compared to that in urban residents, the overall prevalence in rural residents declined more, and it was lower in 2015 than in 2004.Limitations: The results may not apply to the population from other regions.Conclusions: Despite of the stable overall prevalence, mental disorders beyond psychotic disorders should be focused on, especially alcohol abuse and major depressive disorders.

Backgrounds: Little is known about the variation in sleep quality and its association with coping style and mental health in 21st century China, despite of enormous socioeconomic changes. This study aims to document the variation in sleep quality and its contribution to the association between coping style and mental health in China.Methods: Pooled cross-sectional data of 46,561 adults was obtained from the 2004 and 2015 mental health surveys conducted in Shandong Province, China. A Simplified Coping Style Questionnaire and the Pittsburgh Sleep Quality Index were assessed, with mental health measured by the General Health Questionnaire (GHQ). A mediation regression model was run to test the mediating effect of sleep quality.Results: Above 10% reported poor sleep quality or median-to-high risk of mental disorders according to GHQ results in year 2015, and a significant but small improvement for sleep quality and mental health came during the studied decade, with the exception of poor sleep quality increasing among males. In 2015, a one-point increase in sleep quality score was associated with an increase of 0.17 (95% CI, 0.16-0.18) and 0.16 (95% CI, 0.14-0.17) points on the GHQ for males and females, respectively. Sleep quality mediated the relationship between negative tendency of coping style and elevated GHQ scores, and the mediating effects grew stronger in 2015 than those in 2004.Limitation: The study is a cross-sectional study, and the sample is not nationally representative.Conclusion: An integrative intervention of mental health promotion is recommended to account for sleep quality and coping strategies..

Growing epidemiological evidence has shown that exposure to ambient air pollution contributes to poor sleep quality. However, whether variability in air pollution exposure affects sleep quality remains unclear. Based on a large sample in China, this study linked individual air pollutant exposure levels and temporal variability with subjective sleep quality. Town-level data on daily air pollution concentration for 30 days prior to the survey date were collected, and the monthly mean value, standard deviations, number of heavily polluted days, and trajectory for six common pollutants were calculated to measure air pollution exposure and its variations. Sleep quality was subjectively assessed using the Pittsburgh Sleep Quality Index (PSQI), and a PSQI score above 5 indicated overall poor sleep quality. Multilevel and negative control models were used. Both air pollution exposure and variability contributed to poor sleep quality. A one-point increase in the one-month mean concentration of particulate matter with aerodynamic diameters of ≤2.5 μm (PM 2.5) and ≤10 μm (PM 10) led to 0.4% (95% confidence interval (CI): 1.002–1.006) and 0.3% (95% CI: 1.001–1.004) increases in the likelihoods of overall poor sleep quality (PSQI score >5), respectively; the odds ratios of a heavy pollution day with PM 2.5 and PM 10 were 2.2% (95% CI: 1.012–1.032) and 2.2% (95% CI: 1.012–1.032), respectively. Although the mean concentrations of nitrogen dioxide, sulfur dioxide, and carbon monoxide met the national standard, they contributed to the likelihood of overall poor sleep quality (PSQI score >5). A trajectory of air pollution exposure with maximum variability was associated with a higher likelihood of overall poor sleep quality (PSQI score >5). Subjective measures of sleep latency, duration, and efficiency (derived from PSQI) were affected in most cases. Thus, sleep health improvements should account for air pollution exposure and its variations in China under relatively high air pollution levels. [Display omitted] • Ambient air pollution exposure contributed to multiple sleep quality problems. • Variability in air pollution exposure was negatively associated with sleep quality. • Common air pollutants had differential impacts on sleep quality. • Low level CO, SO 2 , and NO 2 exposure impaired sleep quality. • Sleep latency, duration, and efficiency were affected by air pollution exposure.

Aim Background Methods Results Conclusions Implications for nursing and health policy This study aimed to assess the potential mediating roles of nurses' job satisfaction and burnout in the association between decent work and turnover intention.There is a global challenge of nursing shortages in healthcare systems worldwide. Decent work is crucial for safeguarding the rights and professional development outcomes of nurses. However, there is currently limited research on decent work among nurses, and there is a lack of studies exploring the relationships between nurses' decent work, job satisfaction, burnout, and turnover intention.A cross‐sectional survey design was employed with a sample of 460 nurses from three hospitals: The Affiliated Hospital of Hangzhou Normal University, Hangzhou Third People's Hospital, and Hangzhou Red Cross Hospital. The STROBE checklist was used. Mediation analysis using the PROCESS Macro was used to examine the relationships between decent work, job satisfaction, burnout, and turnover intention.The results showed that nurses' perception of decent work directly influences their turnover intention. Additionally, these findings strongly support the role of job satisfaction and burnout as mediating factors in the relationship between decent work and turnover intention.Decent work reduces nurse burnout and turnover intention of enhancing their job satisfaction.This study's findings have important implications for healthcare organizations and policymakers. Recognizing the pivotal role of decent work in nurses' job satisfaction and well‐being can guide the development of strategies to improve working conditions and reduce turnover rates. It is imperative for healthcare institutions to prioritize creating safe, supportive, and equitable work conditions for nurses, as this can contribute to higher job satisfaction and, subsequently, lower turnover rates.

Background: This study integrates data from high-quality mental health surveys in five provinces in China to examine the prevalence, demographic correlates, age of onset, and comorbidity of alcohol use disorder (AUD).Methods: The five cross-sectional surveys initially screened a representative sample of 74,752 community-living adults (94% response rate) from a sampling population including over 12% of China's adult population. Psychiatrists then administered a detailed diagnostic exam to an enriched sample of 21,015 respondents (95% response rate). The prevalence of AUD in females in China is below 0.5%, so we limited our analysis to 9619 males who completed the diagnostic interview.Results: Using meta-analyses to summarize estimates across the five locations, the current (30-day) prevalence of AUD among adult Chinese males was 9.8% (95% CI=5.7-16.9%), but there was wide cross-province variation. After adjusting for age and other demographic variables, the prevalence of AUD was significantly lower in single men than in married men (OR=0.4, CI=0.2-0.7), lower in men who were not currently working than in men who were currently working (OR=0.7, CI=0.5-0.96), and lower in men with comorbid mental disorders than in men without comorbid mental disorders (OR=0.4, CI=0.2-0.8). The risk of developing AUD peaked at 30 years of age.Conclusions: Substantial differences in the demographic correlates and age of onset of AUD in men in China compared to those reported in other countries highlight the importance of understanding the country-specific and region-specific profile of AUD before developing intervention and prevention strategies.

As natural experiments, famines provide a unique opportunity to test the health consequences of nutritional deprivation during the critical period of early life. Using data on 4972 Chinese born between 1956 and 1963 who participated in a large mental health epidemiology survey conducted between 2001 and 2005, we investigated the potential impact of exposure to the 1959–1961 Chinese Famine in utero and during the early postnatal life on adult mental illness. The risk of mental illness was assessed with the 12-item General Health Questionnaire (GHQ-12) and eight other risk factors, and the famine impact on adult mental illness was estimated by difference-in-difference models. Results show that compared with unexposed women born in 1963, women born during the famine years (1959–1961) had higher GHQ scores (increased by 0.95 points; CI: 0.26, 1.65) and increased risk of mental illness (OR = 2.80; CI: 1.23, 6.39); those born in 1959 were the most affected and had GHQ scores 1.52 points higher (CI: 0.42, 2.63) and an OR for mental illness of 4.99 (CI: 1.68, 14.84). Compared to men in the 1963 birth cohort, men born during the famine had lower GHQ scores (decreased by 0.89 points; CI: −1.59, −0.20) and a nonsignificant decrease in the risk of mental illness (OR = 0.60; CI: 0.26, 1.40). We speculate that the long-term consequences of early-life famine exposure include both the selection of the hardiest and the enduring deleterious effects of famine on those who survive. The greater biological vulnerability and stronger natural selection in utero of male versus female fetuses during severe famine may result in a stronger selection effect among men than women, obscuring the deleterious impact of famine exposure on the risk of mental illness in men later in life.
