Background: In the context of rapid aging, "empty nest syndrome" is becoming a major public health concern. The causal effects of empty nest on depressive symptoms have been studied in developed countries, but the mediating mechanism of depressive symptoms in the association between empty nest and cognitive impairments has not been studied. This study estimated the causal association of empty nest with depressive symptoms and cognitive impairments in China, and then estimated how depression mediates the association between empty nest and cognitive impairments.Methods: Using data of 23,614 urban older adults (65+) obtained from the Shandong Province Aging and Mental Health Survey in 2020, a weighted linear regression model combined with instrumental variable was applied to explore the causal effects of empty nest, and a four-step mediation model was run to test the mediator of depressive symptoms. The Ascertain Dementia 8-item Questionnaire and Patient Health Questionnaire-9 were used to measure cognitive impairments and depressive symptoms.Results: Empty nest was associated with 0.13 (95%CI: 0.04-0.23) and 0.23 (95%CI: 0.14-0.33) increases in the Ascertain Dementia 8-item Questionnaire and the Patient Health Questionnaire-9 scores, respectively. The association between empty nest and the Ascertain Dementia 8-item Questionnaire scores was mediated by the Patient Health Questionnaire-9 scores.Conclusions: Empty nest affected depression in adulthood with cognitive impairments. A focus on integrative intervention for empty nesters is recommended, taking depression and cognition into account.Limitations: It is a cross-sectional study and the data is not nationally representative.

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..
