Lu L, Dong M, Lok GKI, Feng Y, Wang G, Ng CH, Ungvari GS, Xiang YT. Worldwide prevalence of sexual harassment towards nurses: A comprehensive meta-analysis of observational studies. J Adv Nurs 2020; 76:980-990. [PMID: 31960498 DOI: 10.1111/jan.14296] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Revised: 12/02/2019] [Accepted: 12/10/2019] [Indexed: 12/29/2022]
Abstract
AIMS Sexual harassment towards nurses is a major concern universally, but no meta-analysis on the worldwide prevalence of sexual harassment towards nurses has yet been published. This study examined the worldwide prevalence of sexual harassment against nurses and explored its moderating factors. DESIGN Meta-analysis of observational studies. DATA SOURCES The PubMed, PsycINFO, EMBASE, and Web of Science databases from their commencement date to February 2018 were systematically and independently searched by two investigators. REVIEW METHODS Data on the prevalence of sexual harassment experienced by nurses were extracted and pooled using the random-effects model. RESULTS A total of 43 studies covering 52,345 nurses were included in the analyses. Female nurses accounted for 83.87% of the 32,970 subjects in 25 studies with available data on gender ratio. The prevalence of sexual harassment towards nurses in the past 12 months and during nursing career were 12.6% (95% CI: 10.9-14.4%) and 53.4% (95% CI: 23.1-83.7%), respectively. Gender, use of the WHO questionnaires, lower middle-income and high-income countries, sample size, survey year, and mean age of subjects were significantly associated with the prevalence of sexual harassment. CONCLUSION The high prevalence of sexual harassment against nurses found in this meta-analysis represents the ongoing sexism and deleterious effects (e.g., poor work quality and efficiency, increased stress and job dissatisfaction) in the profession. Appropriate preventive measures, training, and empowerment of nurses are needed to ensure workplace safety and equality in this profession. IMPACT The study addressed the worldwide prevalence of sexual harassment against nurses and its moderating factors. Health authorities and hospital administrators should develop organizational policy and preventive strategies to ensure nurses' workplace safety and equality.

Abstract
OBJECTIVE This meta-analysis examined the prevalence of poor sleep quality and its associated factors in patients with hypertension in China. METHODS Both English (PubMed, PsycINFO, EMBASE) and Chinese (Wan Fang Database and Chinese National Knowledge Infrastructure) databases were systematically and independently searched. The random-effects model was used to estimate the prevalence of poor sleep quality in Chinese patients with hypertension. The funnel plot and Egger's tests were used to assess publication bias. RESULTS The prevalence of poor sleep quality in 24 studies with 13,920 hypertensive patients was 52.5% (95% confidence interval [CI]: 46.1-58.9%). In contrast, the prevalence of poor sleep quality in six studies with 5,610 healthy control subjects was 32.5% (95% CI: 19.0-49.7%). In these studies, compared to healthy controls, the pooled odds ratio (OR) of poor sleep quality was 2.66 (95% CI: 1.80-3.93) for hypertensive patients. Subgroup and meta-regression analyses revealed that patients in hospitals were more likely to have poor sleep quality than patients in the community. Studies with smaller sample size, studies using convenience or consecutive sampling and those published in Chinese reported higher prevalence of poor sleep quality. Furthermore, poor sleep quality was more common in older and male hypertensive patients, while the proportion of poor sleep quality was negatively associated with survey year. CONCLUSION Appropriate strategies for screening, prevention, and treatment of poor sleep quality in this population should be developed.

Abstract
OBJECTIVE Aggression is common in patients with schizophrenia and is clinically significant, but its prevalence is inconsistent across studies. This is a meta-analysis of the prevalence of aggression and its associated factors in patients with schizophrenia. METHODS PubMed, EMBASE, PsycINFO, the Cochrane Library, Medline and Web of Science databases were systematically searched. Studies that reported the prevalence of aggression in patients with schizophrenia using the Modified Overt Aggression Scale (MOAS) were included and analyzed using the random-effects model. RESULTS Fifteen studies with 4855 patients were initially included; of these, 13 studies with 3929 patients were pooled in the final meta-analysis. The pooled prevalence of aggression was 33.3% (95%CI: 21.5%-47.7%); specifically, the estimated prevalence of verbal, property-oriented, auto and physical aggression were 42.6% (95%CI: 17.0%-72.9%), 23.8% (95%CI: 10.1%-46.4%), 23.5% (95%CI: 6.5%-57.7%), and 23.7% (95%CI: 10.4%-45.3%), respectively. Subgroup analyses revealed that different MOAS cut-off values (P < 0.001) and source of patients (inpatients vs. community-dwelling patients) significantly moderated the results (P < 0.001). Meta-regression analyses found that studies published recently reported higher aggression rate, while higher quality assessment score was associated with lower aggression rate (both P < 0.01). CONCLUSIONS This meta-analysis confirmed that aggression is common in schizophrenia patients. Considering the significant clinical risk issues, appropriate treatments and effective management of aggression in this population need to be developed.

Abstract
BACKGROUND Smoking is common among nursing students worldwide, but the reported prevalence is inconsistent across epidemiological studies. This is a meta-analysis of the prevalence of smoking in nursing students worldwide. DESIGN Meta-analysis of observational studies. SAMPLE A total of 46 studies were included in this meta-analysis. METHOD Electronic databases (PubMed, Medline, PsycINFO, EMBASE and Web of science) were independently and systematically searched by two investigators from their commencement date up to 12 May 2018. Studies that reported the smoking rate of nursing students were included and analyzed using random-effects model. RESULTS The pooled prevalence of current smoking was 26.6% (95% CI: 22.9-30.4%), while pooled prevalence of previous smoking was 15.5% (95% CI: 11.8-19.3%). Subgroup analyses showed that smoking rate was higher in male compared with female students (39% vs 25.2%, P < .001), while survey time, sample size, age, study design and academic year did not moderate the smoking rate (all P > .05). CONCLUSION This meta-analysis confirmed that smoking is common in nursing students. Considering the negative impact of smoking on health, appropriate smoking cessation measures for nursing students should be developed.

Abstract
Major depressive disorder (MDD) is a common psychiatric disorder in China, but its reported treatment rate varies largely across different studies. The objective of this meta-analysis was to determine the pooled treatment rate for people with MDD in China and its associated factors. Both English (PubMed, Cochrane Library, PsycINFO, Web of Science) and Chinese (Chinese National Knowledge Infrastructure, WanFang and SinoMed) databases were searched from their commencement date to November 13, 2018. Epidemiological studies that reported the treatment rate of MDD were included and synthesized using a random effects model. Fifteen studies covering 609,054 participants were included. The pooled treatment rate for MDD in China was 19.5% (95% CI: 10.7%-28.4%). Among the 15 studies, 9 reported the number of patients who received treatments in psychiatric hospitals with a pooled treatment rate of 5.2% (95% CI: 2.8%-7.5%). Meta-regression found that study quality (β = 0.131, P = 0.028) and male gender (β = 0.006, P = 0.039) were significantly associated with a higher treatment rate for MDD. In China, the treatment rate for MDD, particularly in psychiatric hospitals, was low. Effective public education and increasing access to mental health services will probably increase the number of people seeking and receiving treatment.

Abstract
AIMS Bipolar disorder (BD) is a severe psychiatric disorder associated with a high risk of suicide. This meta-analysis examined the prevalence of suicide attempts (SA) in patients with BD and its associated factors. METHODS A systematic literature search was conducted in the PubMed, PsycINFO, EMBASE and Web of Science databases from their inception to 11 June 2018. The prevalence of SA in BD was synthesised using the random-effects model. RESULTS The search identified 3451 articles of which 79 studies with 33 719 subjects met the study entry criteria. The lifetime prevalence of SA was 33.9% (95% CI 31.3-36.6%; I2 = 96.4%). Subgroup and meta-regression analyses revealed that the lifetime prevalence of SA was positively associated with female gender, BD-I, BD Not Otherwise Specified and rapid cycling BD subtypes, income level and geographic region. CONCLUSION This meta-analysis confirmed that SA is common in BD and identified a number of factors related to SA. Further efforts are necessary to facilitate the identification and prevention of SA in BD. Long-term use of mood stabilisers coupled with psycho-social interventions should be available to BD patients to reduce the risk of suicidal behaviour.

Abstract
To investigate the effectiveness of the Clubhouse Model of Psychosocial Rehabilitation on psychosocial functions and recovery of native Chinese individuals with schizophrenia in a community sample. A randomized controlled design was used. A total of 56 participants were recruited from a community sample for a study lasting 6 months, but five participants dropped out. Twenty-eight participants attended the Clubhouse program, and twenty-three participants served as controls. Standardized assessments were performed on three areas at the baseline and the 6-month follow-up: 1. symptom reduction; 2. social function, self-determination, and quality of life; and 3. rehospitalization rate. Compared to the controls, the Clubhouse participants showed reductions in psychiatric symptoms and better social function, self-determination, and quality of life (p < .05), but with no difference in the rehospitalization rate between Clubhouse members and the controls. The Clubhouse Model demonstrates its effectiveness and shows its viability as a service delivery model in psychosocial rehabilitation for individuals with schizophrenia in mainland China.

Abstract
AIMS To examine the average point prevalence of major depressive disorder in people with Type 2 diabetes and its associated factors in a comprehensive meta-analysis. METHODS Two researchers independently conducted a systematic literature search of PubMed, EMBASE, PsycINFO and Cochrane databases. Studies reporting the prevalence of major depressive disorder in people with Type 2 diabetes were identified and analysed using a random-effects model. RESULTS A total of 26 studies meeting the inclusion criteria were included in the study. The point prevalence of major depressive disorder was 14.5% (95% CI 7.9-25.3; I²=99.65). People with Type 2 diabetes were more likely to have major depressive disorder compared with the general population (odds ratio 1.73, 95% CI 1.38-2.16). Subgroup and meta-regression analyses showed that study site, study type, diagnostic criteria and age significantly moderated the prevalence of major depressive disorder. CONCLUSIONS In this meta-analysis, the average point prevalence of major depressive disorder in people with Type 2 diabetes was high. Routine screening and more effective interventions should be implemented for this population.

Abstract
BACKGROUND Suicide attempt (SA), which is one of the strongest predictors of completed suicide, is common in major depressive disorder (MDD) but its prevalence across epidemiological studies has been mixed. The aim of this comprehensive meta-analysis was to examine the pooled prevalence of SA in individuals with MDD. METHODS A systematic literature search was conducted in PubMed, Embase, PsycINFO, Web of Science and Cochrane Library from their commencement date until 27 December 2017. Original studies containing data on prevalence of SA in individuals with MDD were analyzed. RESULTS In all, 65 studies with a total of 27 340 individuals with MDD were included. Using the random effects model, the pooled lifetime prevalence of SA was 31% [95% confidence interval (CI) 27-34%], 1-year prevalence was 8% (95% CI 3-14%) and 1-month prevalence was 24% (95% CI 15-34%). Subgroup analyses revealed that the lifetime prevalence of SA was significantly associated with the patient setting, study region and income level, while the 1-month prevalence of SA was associated with only the patient setting. CONCLUSION This meta-analysis confirmed that SA was common in individuals with MDD across the world. Careful screening and appropriate interventions should be implemented for SA in the MDD population.

Examining the association between apparent temperature and admissions for schizophrenia in Hefei, China, 2005-2014: A time-series analysis. THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 672:1-6. [PMID: 30954808 DOI: 10.1016/j.scitotenv.2019.03.436] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/25/2018] [Revised: 03/26/2019] [Accepted: 03/27/2019] [Indexed: 05/21/2023]
Abstract
BACKGROUND Many studies have investigated the association between schizophrenia and daily mean temperature, but the conclusions were not consistent. Apparent temperature (AT), a comprehensive indicator of temperature and humidity, reflected human thermal sensation more objectively than temperature. We aimed to investigate the relationship between high/low AT and schizophrenia hospitalizations in Hefei, China, and further to identify vulnerable subpopulations. METHODS Poisson generalized linear regression model combined with distributed lag non-linear model (DLNM) was applied to quantify the relationship between AT and schizophrenia hospitalizations, compared with the AT of minimum admissions (3.3 °C). Stratified analysis was conducted by sex, marital status and age. Separate models for AT and temperature were compared as well. RESULTS The high AT (90th, 28.3 °C) exerted the greatest effect at lag0, with RR = 1.062 (95%CI, 1.019-1.106). The effect of the low AT (10th, -4.7 °C) was first observed at lag3 (RR = 1.007, 95%CI: 1.000-1.015), and increased to the maximum at lag7 (RR = 1.018, 95%CI: 1.009-1.027). The male patients, the married patients and patients aged 41-60 years appeared to be more vulnerable to both high and low ATs. The values of Akaike Information Criterion and mean squared error (MSE) in model with AT were smaller than that with temperature. CONCLUSIONS Both high and low ATs were associated with increase in schizophrenia hospitalizations. More protective measures should be taken to avoid adverse AT exposure in susceptible groups.

Song M, Wang L, Zhao XC, Li N, Wang R, Gao YY, Yu LL, An CX, Wang XY. The prevalence and risk of DSM-IV axis I disorder in adults with early-life earthquake stress: A cross-sectional study. Int J Dev Neurosci 2019; 76:65-71. [PMID: 31229525 DOI: 10.1016/j.ijdevneu.2019.06.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2019] [Revised: 05/22/2019] [Accepted: 06/18/2019] [Indexed: 11/30/2022] Open
Abstract
OBJECTIVES Tangshan earthquake which had a magnitude of 7.8 killed approximately 250,000 people in China in 1976. In the present study, we sought to determine the prevalence and risks of mental disorders in adults who experienced earthquake as an infant or in the prenatal period. METHODS This cross-sectional cohort study recruited participants based on the urban resident registry of Tangshan, Hebei province, 2013 using a multistage stratified cluster sampling method with selection probabilities proportional to size. We recruited subjects who were born between July 29, 1975 and April 28, 1978 that was one year before and 1.9 years after the occurrence of Tangshan Earthquake, respectively. Current psychiatric diagnoses and lifetime psychiatric diagnoses were obtained through the Structured Clinical Interview for DSM-IV Axis I Disorders Patient Research Version. Unconditional logistic regression analysis was performed to analyze risk factors of mental disorders. RESULTS Totally1380 subjects were included with 392 subjects exposed to the earthquake in the fetal period, 399 subjects who experienced the earthquake during their infancy, and 589 subjects who had no exposure to the earthquake. Twenty-one (2.7%; current 1.9%) subjects exposed to earthquake were diagnosed with major depressive disorderversus 2.3% (current 1.5%) in the non-exposure group. Five (0.6%; current 0.6%) subjects with exposure to earthquake had bipolar disorder versus 0.9% in the non-exposure group.Thirteen (1.6%; current 1.6%) subjects with exposure to earthquake had schizophreniaversus 0.2% in the non-exposure group (P=0.006). Furthermore, 5.2% (current 3.7%) subjects with exposure to earthquake had anxiety disorders versus 5.7% (current 3.9%) in the non-exposure group. Moreover, 8.1% (current 7.0%)subjects with exposure to earthquake had alcohol use disorders versus 7.1% (current 5.3%) in the non-exposure group. Furthermore, the prevalence of schizophrenia of the prenatal exposure group (2.3%) was significantly higher than the other two groups (χ2 = 10.273, P = 0.006); however, no statistically significant difference was found in the current and lifetime prevalence of other DSM-IV axis I disorders among the three groups (P > 0.05). Our multivariate regression analysis showed that prenatal earthquake stress exposure was not a significant risk of any of the lifetime or current DSD-IV axis I disorders. CONCLUSION Adults who were exposed to earthquake in the prenatal period had a significantly higher rate of schizophrenia than those who were not exposed or who experienced earthquake in their infancy. No statistically significant difference was found in the current and lifetime prevalence of other DSM-IV axis I disorders between those exposed and those not exposed to earthquake. Furthermore, prenatal earthquake stress exposure was not a significant risk of any of the lifetime or current DSD-IV axis I disorders.

Abstract
AIMS Suicide attempt is an important indicator of suicide and potential future mortality. However, the prevalence of suicide attempts has been inconsistent across studies. This meta-analysis aimed to examine the prevalence of suicide attempts in individuals with schizophrenia and associated correlates. METHODS Relevant publications in Embase, PsycINFO, PubMed, Web of science and Cochrane were systematically searched. Data on the prevalence of suicide attempts in individuals with schizophrenia were pooled using a random-effects model. RESULTS Thirty-five studies with 16 747 individuals with schizophrenia were included. The pooled lifetime prevalence of suicide attempts was 26.8% (95% CI 22.1-31.9%; I2 = 97.0%), while the 1-year prevalence, 1-month prevalence and the prevalence of suicide attempts from illness onset were 3.0% (95% CI 2.3-3.7%; I2 = 95.6%), 2.7% (95% CI 2.1-3.4%; I2 = 78.5%) and 45.9% (95% CI 42.1-49.9%; I2 = 0), respectively. Earlier age of onset (Q = 4.38, p = 0.04), high-income countries (Q = 53.29, p < 0.001), North America and Europe and Central Asia (Q = 32.83, p < 0.001) were significantly associated with a higher prevalence of suicide attempts. CONCLUSIONS Suicide attempts are common in individuals with schizophrenia, especially those with an early age of onset and living in high-income countries and regions. Regular screening and effective preventive measures should be implemented as part of the clinical care.

Abstract
AIMS Suicide-related behaviours are common in schizophrenia and are significantly associated with premature death. The objective of this meta-analysis study was to estimate the pooled prevalence of suicide-related behaviours in schizophrenia patients in China. METHODS The relevant literature was searched systematically via the relevant electronic databases (PubMed, Embase, PsycINFO, Chinese National Knowledge Infrastructure, Wanfang Databases and Chinese Biological Medical Literature Database) from their inception until 14 September 2016. Only original studies that reported the prevalence of suicide-related behaviours including suicidal ideation (SI), suicide plan, suicide attempt (SA) and completed suicide were selected. RESULTS Nineteen articles met the inclusion criteria and were analysed. The pooled lifetime prevalence of SI and SA were 25.8% (95% CI 14.7-41.1%) and 14.6% (95% CI 9.1-22.8%), respectively. The 1-month prevalence of SI was 22.0% (95% CI 18.2-26.4%). Subgroup analyses of lifetime SI and SA showed that gender, sample size, survey year, study location and source of patients have no significant mediating effects on the results. CONCLUSIONS Suicide-related behaviours are common in Chinese schizophrenia patients. Due to the high mortality risk, regular screening and effective suicide prevention programmes are warranted.

Abstract
Cognitive Behavioral Therapy (CBT) is frequently used to attenuate the severity of positive schizophrenia symptoms; however, few studies have focused on attenuating negative symptoms. Recently, researchers have become interested in the effects of mindfulness-based intervention (MBI) on schizophrenia, but the lack of evidence-based results from random clinical trials (RCTs) has limited their effectiveness. Moreover, longitudinal data must be examined using appropriate study designs. We recruited 60 schizophrenia patients and randomly assigned them to an MBI or to a treatment-as-usual group. Negative symptoms, positive symptoms, mindfulness, and depression were assessed at baseline, post-course, and at a 3-month follow-up. Descriptive analysis and generalized estimating equations (GEEs) were used to examine the effects of MBI. We found that MBI mitigated the severity of negative symptoms and of general schizophrenic psychopathology except for the positive symptoms and for those of depression. Unexpectedly, we did not find long-term effect of mindfulness on negative symptoms. Larger sample sizes, long-term practical course, more rigorous study procedures, and a double-blind design should be considered in future studies.

Abstract
Falls are common in older adults with psychiatric disorders, but the epidemiological findings have been inconsistent. This meta-analysis examined the prevalence of falls in older psychiatric patients and its moderating factors. PubMed, EMBASE, Web of Science and PsycINFO databases were independently searched by three investigators from their inception date to Nov 31, 2017. The random effects meta-analysis was used to synthesize the prevalence of falls, while meta-regression and subgroup analyses were conducted to explore the moderating factors. Sixteen of the 2061 potentially relevant papers met the entry criteria for the meta-analysis. The pooled lifetime prevalence of falls was 17.25% (95% confidence interval: 13.14%-21.35%). Neither univariate and nor multivariate meta-regression analyses revealed any moderating effects of the study region, duration, sample size, and quality on the prevalence of falls (P values > 0.05). Falls in older adults with psychiatric disorders are common.

Abstract
BACKGROUND Family caregivers play crucial roles in taking care of people experiencing schizophrenia in the community. The burdens on and needs of caregivers of these patients should be emphasized. This study aimed to explore the perspective of family caregivers of people experiencing schizophrenia in the communities of Beijing in terms of the burdens of care and the acquisition and further need for support in order to provide guidance to health care providers regarding how to target therapeutic interventions for families of individuals experiencing schizophrenia and to provide recommendations for policy makers to tailor countermeasures and services. METHODS A total of 20 family caregivers of schizophrenia patients were enrolled in our study. A face-to-face and semi-structured in-depth qualitative interview study was conducted to explore the caregivers' perspective on the burden on caregivers, support and further needs. This study was conducted in the community health service centres where the family caregivers regularly visit. The study was carried out according to good ethical practices, data analysis and reporting guidelines. RESULTS Most participants reported that they were suffering from heavy life burdens and had negative experiences with respect to obtaining social support, and they emphasized that they would require more support. Economic and daily housework burdens, limited social communication, and psychological stresses were the principal burdens. Support including financial, medical and information and educational support did not satisfy the needs of the caregivers and their patients. More financial support, respect, and rehabilitation institutions were reported to be needs of the caregivers. CONCLUSIONS Family caregivers of people experiencing schizophrenia suffer from heavy physical and psychological burdens; however, the current support provided is insufficient. More services and better public attitudes should be considered for people experiencing schizophrenia and their caregivers.

Abstract
BACKGROUND Depressive symptoms are common in 'left-behind children (LBC)' in China, but their prevalence estimates have been inconsistent. This comprehensive meta-analysis examined the pooled prevalence of depressive symptoms in LBC in China and its associated factors. METHODS Two investigators systematically and independently searched both English (PubMed, PsycINFO, and EMBASE) and Chinese (WanFang Database, CNKI, and SinoMed) databases. Comparative and epidemiological studies reporting the prevalence of depressive symptoms and associated relevant information were included. The prevalence of depressive symptoms was pooled using the random-effects model. RESULTS A total of 39 studies covering 31,663 LBC and 20,049 non-LBC controls were included in the meta-analysis. The figures of pooled prevalence of depressive symptoms in LBC and non-LBC were 30.7% and 22.8%, respectively. Subgroup analyses revealed that the use of different scales was significantly associated with the prevalence of depressive symptoms. Compared with non-LBC, LBC were more likely to suffer from depressive symptoms (OR = 1.7, 95% CI: 1.4-1.9). CONCLUSIONS This meta-analysis confirmed that the prevalence of depressive symptoms in LBC is common in China. In order to reduce the risk of depressive symptoms in this vulnerable segment of the population, the development of screening and therapeutic interventions is urgently needed.

Abstract
Schizophrenia (SCZ) is a devastating mental disorder with poorly defined underlying molecular mechanisms. The gut microbiome can modulate brain function and behaviors through the microbiota-gut-brain axis. Here, we found that unmedicated and medicated patients with SCZ had a decreased microbiome α-diversity index and marked disturbances of gut microbial composition versus healthy controls (HCs). Several unique bacterial taxa (e.g., Veillonellaceae and Lachnospiraceae) were associated with SCZ severity. A specific microbial panel (Aerococcaceae, Bifidobacteriaceae, Brucellaceae, Pasteurellaceae, and Rikenellaceae) enabled discriminating patients with SCZ from HCs with 0.769 area under the curve. Compared to HCs, germ-free mice receiving SCZ microbiome fecal transplants had lower glutamate and higher glutamine and GABA in the hippocampus and displayed SCZ-relevant behaviors similar to other mouse models of SCZ involving glutamatergic hypofunction. Together, our findings suggest that the SCZ microbiome itself can alter neurochemistry and neurologic function in ways that may be relevant to SCZ pathology.

Abstract
With the widespread implementation of antiretroviral therapy in many countries, the HIV/AIDS epidemic has declined. However, little is known about the prevalence of adherence rate to Highly Active Antiretroviral Therapy (HAART) in patients with HIV infection in China. This is the first meta-analysis of cross-sectional studies of treatment adherence (≥ 95%) to HAART in Chinese patients. Both English (PubMed, PsycINFO, EMBASE, and Web of Science) and Chinese (WanFang, CNKI, and SinoMed) databases were systematically and independently searched by three investigators. Studies with adherence rate estimates of HAART were included. Adherence rate estimates of each eligible study were extracted and pooled using the random-effects model. A total of 40 studies conducted in China were eligible and analyzed. The mean rate of ≥ 95% adherence to HAART was 81.1% (95%CI: 75.1%-88.0%, I2 = 97.3%) at one week, 80.9% (95%CI: 74.7%-85.9%, I2 = 96.6%) at one month, and 68.3% (95%CI: 46.1%-84.4%, I2 = 97.1%) at 3 months or longer. Subgroup analyses revealed that samples with no gender predominance, low education level, middle economic region, rural area, older age (42.3 years), and recent publication (2013 or later) were correlated to higher HAART adherence. The average rate of HAART adherence was relatively high in China, which indicates effective HIV/AIDS policy, prevention and control measures. However, the HAART adherence rate decreased over the study time period.

Rs7219 Regulates the Expression of GRB2 by Affecting miR-1288-Mediated Inhibition and Contributes to the Risk of Schizophrenia in the Chinese Han Population. Cell Mol Neurobiol 2018; 39:137-147. [PMID: 30474799 DOI: 10.1007/s10571-018-0639-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2018] [Accepted: 11/16/2018] [Indexed: 01/04/2023]
Abstract
In the present study, we examined a potential genetic association between the variant rs7219 within the 3'-UTR of GRB2 and the susceptibility to schizophrenia (SCZ) and bipolar disorder (BD) in the Chinese Han population. A genetic association study, including 548 SCZ patients, 512 BD patients, and 598 normal controls, was conducted in the Chinese Han population. Genotyping was performed through the Sequenom MassARRAY technology platform. The expression of GRB2 was detected using quantitative real-time polymerase chain reaction (qRT-PCR). A dual-luciferase reporter assay was performed to determine whether miR-1288 could bind to the 3'-UTR region of GRB2 containing rs7219. We found that rs7219 was significantly associated with the susceptibility to SCZ under different genetic models, including additive [OR (95% CI) = 1.24 (1.02-1.49), P = 0.027], dominant [OR (95% CI) = 1.31 (1.04-1.66), P = 0.025], and allelic models[OR (95% CI) = 1.24 (1.03-1.49), P = 0.027]. However, no significant associations were found between rs7219 and the risk for BD (all P > 0.05). Moreover, we observed that the expression of GRB2 significantly decreased in SCZ patients compared with the controls (P = 0.004). The dual-luciferase reporter assay showed that the minor allele C of rs7219 significantly decreased the luciferase activity by binding miR-1288 (P < 0.001). In summary, we are the first to reveal that rs7219 is significantly associated with the susceptibility to SCZ in the Chinese Han population. Moreover, the minor allele C of rs7219 is identified as a risk allele for SCZ because it generates a binding site for miR-1288, thereby resulting in decreased expression of GRB2 and ultimately increasing the risk of SCZ.

Abstract
BACKGROUND More than half of the global population currently lives in cities, with an increasing trend for further urbanization. Living in cities is associated with increased population density, traffic noise and pollution, but also with better access to health care and other commodities. METHODS This review is based on a selective literature search, providing an overview of the risk factors for mental illness in urban centers. RESULTS Studies have shown that the risk for serious mental illness is generally higher in cities compared to rural areas. Epidemiological studies have associated growing up and living in cities with a considerably higher risk for schizophrenia. However, correlation is not causation and living in poverty can both contribute to and result from impairments associated with poor mental health. Social isolation and discrimination as well as poverty in the neighborhood contribute to the mental health burden while little is known about specific interactions between such factors and the built environment. CONCLUSION Further insights on the interaction between spatial heterogeneity of neighborhood resources and socio-ecological factors is warranted and requires interdisciplinary research.

Influence of CTNNB1 rs2953 polymorphism on schizophrenia susceptibility in Chinese Han population through modifying miR-485 binding to CTNNB1. GENES BRAIN AND BEHAVIOR 2018; 18:e12524. [PMID: 30280518 DOI: 10.1111/gbb.12524] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2018] [Accepted: 09/28/2018] [Indexed: 12/21/2022]
Abstract
Schizophrenia (SCZ) and bipolar disorder (BD) are two major neuropsychiatric diseases that are the most substantial causes of disability and mortality worldwide. CTNNB1 encodes beta-catenin, an important protein in canonical Wnt signaling. We aimed to investigate the association between the rs2953 of CTNNB1 and the risk of SCZ and BD and to further explore the function of rs2953. A total of 1658 samples (548 SCZ cases, 512 BD cases, and 598 controls) were examined in terms of the genotype of CTNNB1 rs2953. The mRNA expression level of CTNNB1 significantly increased in the SCZ and BD groups compared with that in the control group. Significant association remained between CTNNB1 3'-untranslated region (UTR) variant rs2953 and SCZ susceptibility (additive and dominant model) after gender and age were adjusted. rs2953 disrupted the binding of CTNNB1 and miR-485. miR-485 significantly suppressed the luciferase activity of CTNNB1-T vector by binding to the CTNNB1 3'-UTR containing the T allele of rs2953. The mRNA expression of CTNNB1 can be used as a biomarker for the diagnosis of SCZ and BD. The 3'-UTR variant rs2953 in CTNNB1 influences the risk of SCZ in the Han Chinese population and modifies the binding of miR-485 to CTNNB1.

Abstract
The impact of schizophrenia on quality of life (QOL) is significantly influenced by sociocultural factors. This meta-analysis systematically compared QOL between patients with schizophrenia and healthy controls in China. PubMed, PsycINFO, Embase, Chinese National Knowledge Infrastructure (CNKI), SinoMed and WanFang databases were searched to identify case-control studies. Standardized mean differences (SMDs) and 95% confidence interval (CI) were calculated using random effect models. Eighteen case-control studies comparing QOL between schizophrenia patients (n = 2,425) and healthy controls (n = 2,072) were included in the analyses. Compared with healthy controls, schizophrenia patients had significantly poorer overall QOL [11 studies; SMD:-1.07 (95%CI:-1.44, -0.70), P < 0.001] as well as in the physical, psychological, social and environmental QOL domains. Subgroup analyses revealed that poorer QOL was significantly associated with diagnostic criteria, study location, female gender, older age and inpatient status. Older schizophrenia patients had lower physical and psychological QOL, while inpatients had lower psychological QOL. In conclusion, compared with healthy controls, schizophrenia patients in China have significantly lower QOL.

Comparative efficacy and safety between amisulpride and olanzapine in schizophrenia treatment and a cost analysis in China: a systematic review, meta-analysis, and cost-minimization analysis. BMC Psychiatry 2018; 18:286. [PMID: 30185173 PMCID: PMC6125952 DOI: 10.1186/s12888-018-1867-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Accepted: 08/28/2018] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Amisulpride was introduced into China in 2010 as a second-generation atypical antipsychotic, while olanzapine has been on the market since 1999 as one of the leading treatments for schizophrenia in China. Since more Chinese patients are gaining access to amisulpride, the study aims to compare the efficacy, safety, and costs between amisulpride and olanzapine for schizophrenia treatment in China. METHODS PubMed, Embase, the Cochrane library, China National Knowledge Infrastructure (CNKI) and WanFang database were systematically searched for randomized controlled trials (RCTs) up to July 2018. The Cochrane Risk of Bias tool was utilized to assess the quality of included studies. A meta-analysis was performed to compare the efficacy and safety of amisulpride and olanzapine, followed by a cost-minimization analysis using local drug and medical costs reported in China. RESULTS Twenty RCTs with 2000 patients were included in the systematic review. There were no significant differences between amisulpride and olanzapine on efficacy measures based on scores from the Positive and Negative Syndrome Scale, the Scale for the Assessment of Negative Symptoms, the Brief Psychiatric Rating Scale and the Clinical Global Impressions-Severity or Improvement. For safety outcomes, amisulpride was associated with lower fasting blood glucose and less abnormal liver functions as well as significantly lower risks of weight gain, constipation, and somnolence; olanzapine was associated with significantly lower risks of insomnia and lactation/amenorrhea/sexual hormone disorder. No significant differences were found in risks of extrapyramidal symptoms (EPS), tremor, akathisia, abnormal corrected QT interval. Cost-minimization analysis showed that amisulpride was likely to be a cost-saving alternative in China, with potential savings of 1358 Chinese Yuan (CNY) per patient for a three-month schizophrenia treatment compared with olanzapine. CONCLUSION As the first meta-analysis and cost-minimization analysis comparing the efficacy, safety and cost of amisulpride and olanzapine within a Chinese setting, the study suggests that amisulpride may be an effective, well-tolerated, and cost-saving antipsychotic drug alternative in China.

Abstract
BACKGROUND AND AIMS Internet addiction disorder (IAD) is common in university students. A number of studies have examined the prevalence of IAD in Chinese university students, but the results have been inconsistent. This is a meta-analysis of the prevalence of IAD and its associated factors in Chinese university students. METHODS Both English (PubMed, PsycINFO, and Embase) and Chinese (Wan Fang Database and Chinese National Knowledge Infrastructure) databases were systematically and independently searched from their inception until January 16, 2017. RESULTS Altogether 70 studies covering 122,454 university students were included in the meta-analysis. Using the random-effects model, the pooled overall prevalence of IAD was 11.3% (95% CI: 10.1%-12.5%). When using the 8-item Young Diagnostic Questionnaire, the 10-item modified Young Diagnostic Questionnaire, the 20-item Internet Addiction Test, and the 26-item Chen Internet Addiction Scale, the pooled prevalence of IAD was 8.4% (95% CI: 6.7%-10.4%), 9.3% (95% CI: 7.6%-11.4%), 11.2% (95% CI: 8.8%-14.3%), and 14.0% (95% CI: 10.6%-18.4%), respectively. Subgroup analyses revealed that the pooled prevalence of IAD was significantly associated with the measurement instrument (Q = 9.41, p = .024). Male gender, higher grade, and urban abode were also significantly associated with IAD. The prevalence of IAD was also higher in eastern and central of China than in its northern and western regions (10.7% vs. 8.1%, Q = 4.90, p = .027). CONCLUSIONS IAD is common among Chinese university students. Appropriate strategies for the prevention and treatment of IAD in this population need greater attention.

Abstract
Falls have significant health consequences and are common in psychiatric patients. Findings on the prevalence of falls in Chinese adult and older adult psychiatric inpatients have been inconsistent. This meta-analysis examined the pooled prevalence of falls in adult and older adult psychiatric inpatients in China. Both English (PubMed, EMBASE, Web of Science, PsycINFO, Cochrane Library) and Chinese (China National Knowledge Interne, WanFang Data and SinoMed) databases were searched independently by three reviewers. The pooled prevalence of falls and its 95% confidence intervals (CIs) using the random effects model were calculated. A total of 39 studies covering 204,234 inpatients were analyzed. The pooled prevalence of falls in adult and older adult (≥60 years) patients was 3% (95% CI: 1.8%-5%) and 7.3% (95%CI: 5.0%-10.6%), respectively. Subgroup analyses revealed that the prevalence of falls was significantly associated with the psychiatric diagnostic criteria and study sample size. This meta-analysis found that the prevalence of falls among adult and older adult psychiatric patients in China was significantly high, although less than that was reported from Western psychiatric inpatient settings.

Abstract
BACKGROUND Urban birth and urban living are associated with increased risk of schizophrenia but less is known about effects on more common psychotic experiences (PEs). China has undergone the most rapid urbanization of any country which may have affected the population-level expression of psychosis. We therefore investigated effects of urbanicity, work migrancy, and residential stability on prevalence and severity of PEs. METHODS Population-based, 2-wave household survey of psychiatric morbidity and health-related behavior among 4132 men, 18-34 years of age living in urban and rural Greater Chengdu, Sichuan Province, China. PEs were measured using the Psychosis Screening Questionnaire. RESULTS 1261 (31%) of young men experienced at least 1 PE. Lower levels of PEs were not associated with urbanicity, work migrancy or residential stability. Urban birth was associated with reporting 3 or more PEs (OR: 1.63; 95% CI: 1.25-2.11), after multivariable adjustment, with further evidence (P = .01) this effect was restricted to those currently living in urban environments (OR: 1.78; 95% CI: 1.16-2.72). Men experiencing a maximum of 5 PEs were over 8 times more likely to have been born in an urban area (adjusted odds ratio [AOR] 8.81; 95% CI 1.50-51.79). CONCLUSIONS Men in Chengdu, China, experience a high prevalence of PEs. This may be explained by rapid urbanization and residential instability. Urban birth was specifically associated with high, but not lower, severity levels of PEs, particularly amongst those currently living in urban environments. This suggests that early and sustained environmental exposures may be associated with more severe phenotypes.

Risk behavior in patients with severe mental disorders: a prospective study of 121,830 patients managed in rural households of western China. BMC Psychiatry 2018; 18:134. [PMID: 29776345 PMCID: PMC5960100 DOI: 10.1186/s12888-018-1709-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2017] [Accepted: 04/30/2018] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND The management of severe mental disorder (SMD) patients in communities is an important initiative of healthcare reform in China. Yet the effects in terms of risk behavior of patients are unclear, particularly in rural areas. This study aims to examine high risk behaviors, changing trends, and possible associated factors among SMD patients in the rural areas of western China. METHODS This analysis examined incidence rate (IR) of high risk behavior of 121,830 managed SMD patients in rural area of Sichuan province, based on data from the national system from 2006 to 2013. Register rate, high risk behavior IR, and time distribution and area distribution of high risk behavior were described. Two-level Poisson regression model was used to analyze associates of high risk behavior of patients, which include demographic characteristics at individual level, socio-economic condition and health system indicators at region level. RESULTS It was revealed that 6804 (5.58%) of managed patients were involved in 17,220 high risk behavior events, which gave an overall IR of 0.0998 (per person year) on the basis of 172,564 person years of follow-up. The IR varied widely across municipalities, in the range of 0.0305-0.3397. The IR of high risk behavior in the cohort had increased since 2006, and peaked by 2011, at 0.2392. At the individual level, males aged 25 to 44, who were unmarried and in poverty, illiterate or semiliterate, had a family history of mental disorders and antipsychotic treatments, longer duration illnesses, were associated with an increased IR risk. At the regional level, higher psychiatric practitioner visits and the lower annual net income of rural residents per capita, were associated with an increased IR risk. CONCLUSIONS This is the first large prospective study that revealed the current situation of the register rate, high risk behavior incidence rate in SMD patients in rural area of western China, and examined associates and the differences of high risk behavior of patients among municipalities. The findings may provide evidences that lead to guide prevention and control for risk behavior in SMD patients in rural areas of China, as well as to improve mental health services for this population. It could provide some reference for other developing countries too.

Front Psychiatry 2018; 9:657. [PMID: 30618856 PMCID: PMC6297372 DOI: 10.3389/fpsyt.2018.00657] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2018] [Accepted: 11/19/2018] [Indexed: 11/23/2022] Open
Abstract
Background: Aquaporin 4 (AQP4) polymorphism may influence the required dosage of antipsychotic drugs. However, the roles of AQP4 polymorphisms in the blood-brain barrier (BBB) and different neuroprotective effects need further exploration. This study aims to investigate whether the gene polymorphisms and haplotype of AQP4 are associated with serum S100 calcium-binding protein B (S100B) level and clinical symptoms in patients with schizophrenia (SCZ). Methods: We recruited 190 patients with SCZ. They provided demographic data, completed relevant questionnaires, and submitted samples to test for four AQP4 tag single nucleotide polymorphisms (SNPs) and eight haplotypes. The rating scales of Positive and Negative Syndrome Scale (PANSS), Personal and Social Performance (PSP), the Global Assessment of Functioning (GAF), Clinical Global Impression (CGI) were assessed and serum S100B level were measured repeatedly during antipsychotic treatment at weeks 0 (baseline), 3, 6, and 9. Using generalized estimating equation (GEE) analyses, log-transformed S100B (logS100B) level was tested for associations with haplotype and other dependent variables. Results: Discretization via the median split procedure showed that logS100B level >1.78 or ≤ 1.78 had the best discriminant validity to stratify the patients into two groups. After 9 weeks of treatment, the serum S100B level was decreased. The TAA haplotype of AQP4 SNPs was associated with increased serum S100B level (p = 0.006). The PANSS negative subscale (PANSS-N) (p = 0.001) and Clinical Global Impression-Improvement (CGI-I) (p = 0.003) scores had a positive association with S100B level. Conclusion: Patients with the TAA haplotype of the AQP4 polymorphism are likely to have increased serum S100B level, negative symptoms and poor control of neuroinflammation. A logS100B level >1.78 may be sufficiently specific to predict a higher severity of negative symptoms. Further study including healthy controls and patients with first and recurrent episodes under selective AQP4 modulators will be necessary to explore the profound effects on the treatment of patients with SCZ and may positively influence their overall outcome.

Abstract
BACKGROUND Suicidal behaviors are common in major depressive disorder (MDD) and contribute significantly to premature death. The objective of this meta-analysis is to estimate the pooled prevalence of suicidal behaviors in patients with MDD in China. METHODS The relevant databases in English (PubMed, Embase, PsycINFO and Cochrane Library) and Chinese (Chinese National Knowledge Infrastructure, Wanfang and Chinese Biological Medical Literature) were systematically and independently searched from their inceptions until January 23, 2017. Original studies that reported the prevalence of suicidal behaviors including suicidal ideation (SI), suicide plan (SP), suicide attempt (SA) and completed suicide (CS) were included. RESULTS Thirty three articles that met the inclusion criteria were analyzed. The pooled lifetime prevalence of SI, SP and SA were 53.1% (95% CI: 42.4-63.4%), 17.5% (95% CI: 5.8-42.3%) and 23.7% (95% CI: 19.9-28.0%), respectively. One-month prevalence of SI and SA were 27.7% (95% CI: 15.4-44.5%) and 20.3% (95% CI: 12.1-32.2%), respectively. The pooled prevalence of SA during hospitalization and after onset of MDD were 17.3% (95% CI: 12.4-23.7%) and 42.1% (95% CI: 26.1-60.0%), respectively. Subgroup analyses revealed significant differences in both lifetime prevalence of SI and SA between genders, and between outpatients and inpatients with MDD. CONCLUSION Suicidal behaviors are common in MDD patients in China. Regular screening and effective intervention for suicidal behavior in MDD patients are warranted.

BMC Psychiatry 2017; 17:399.

Abstract
BACKGROUND Schizophrenia is a serious mental disorder largely manageable with atypical antipsychotics; however, these drugs have been associated with glucose/lipid metabolism issues such as diabetes and hyperlipidaemia. Apolipoprotein E (APOE) is the most abundant apolipoprotein, and APOE genotypes have been correlated with lipid metabolism phenotypes in an age-dependent manner. Studies examining the relationship between the APOE genotype and lipid abnormalities in patients with schizophrenia have been inconclusive, but primarily focused on adult patient populations. Therefore, we explored the correlations between the APOE genotype and glucose/lipid metabolism indicators and abnormalities in hospitalized patients 60 years or older with schizophrenia with a history of long-term antipsychotics use. METHODS We assessed APOE genotype, age, weight, height, blood glucose, triglycerides, cholesterol, high-density lipoprotein, and low-density lipoprotein in a total of 294 patients. APOE genotypes were divided into three groups: APOE ε2 (ε2/ε2 and ε2/ε3), APOE ε3 (ε3/ε3), and APOE ε4 (ε3/ε4 and ε4/ε4), and comparisons were conducted among these groups or according to ε2 carrier status. RESULTS APOE ε3/ε3 was the most common genotype (68.3%) and at least one ε3 allele was present in 81.8% of patients. There were no differences in antipsychotics type or dose according to the APOE genotype, but serum cholesterol values varied near significantly (P = 0.052) and low-density lipoprotein values varied significantly according to genotype (P < 0.05, lowest in the APOE ε2 genotype). Men had lower cholesterol and low-density lipoprotein levels (P < 0.05) than women. Compared to patients administered typical antipsychotics, those administered atypical antipsychotics had higher triglyceride, cholesterol, and low-density lipoprotein levels (P < 0.05). Stepwise linear regressions showed that cholesterol and low-density lipoprotein levels were influenced by sex, the APOE ε2 genotype, and atypical antipsychotics use. CONCLUSIONS In the context of atypical antipsychotics use, carriers of the APOE ε2-genotype and male patients with schizophrenia 60 years or older may be less likely to develop a lipid metabolism abnormality.

Abstract
STUDY OBJECTIVES This meta-analysis aimed to determine duration and patterns of sleep in Chinese university students. METHODS English (PubMed, PsycINFO, Embase) and Chinese (SinoMed, Wan Fang Database, and Chinese National Knowledge Infrastructure) databases were systematically and independently searched from their inception until August 16, 2016. Data on sleep duration and sleep patterns of tertiary student population in eligible studies were extracted and pooled using random-effects models. RESULTS A total of 57 studies with 82,055 university students were included in the meta-analysis. Pooled mean sleep duration was 7.08 h/d (95% confidence interval [CI]: 6.84 to 7.32 h/d). The percentage of students with sleep duration shorter than 6 h/d and 7 h/d (short sleep) was 8.4% (95% CI: 5.7% to 12.3%) and 43.9% (95% CI: 36.9% to 51.1%), respectively. In contrast, the percentage of students with sleep duration longer than 8 hours and 9 hours (long sleep) was 18.3% and 5.7%, respectively. The pooled mean bedtime was at 12:51 am. The percentage of university students who fall asleep after midnight was 23.8%. The percentage of students with sleep latency more than 30 minutes was 25.5%. The pooled mean wake-up time was at 8:04 am on weekdays and on weekends. CONCLUSIONS Short sleep duration and unhealthy sleep patterns were found to be common among Chinese university students.

Abstract
Lifetime prevalence of psychotic disorders varies widely across studies. Epidemiological surveys have rarely examined prevalences of specific psychotic disorders other than schizophrenia, and the majority used a single-phase design without employing clinical reappraisal interview for diagnostic verification. The current study investigated lifetime prevalence, correlates and service utilization of schizophrenia-spectrum, affective, and other non-affective psychotic disorders in a representative sample of community-dwelling Chinese adult population aged 16-75 years (N = 5719) based on a territory-wide, population-based household survey for mental disorders in Hong Kong. The survey adopted a 2-phase design comprising first-phase psychosis screening and second-phase diagnostic verification incorporating clinical information from psychiatrist-administered semi-structured interview and medical record review to ascertain DSM-IV lifetime diagnosis for psychotic disorders. Data on sociodemographics, psychosocial characteristics and service utilization were collected. Our results showed that lifetime prevalence was 2.47% for psychotic disorder overall, 1.25% for schizophrenia, 0.15% for delusional disorder, 0.38% for psychotic disorder not otherwise specified, 0.31% for bipolar disorder with psychosis, and 0.33% for depressive disorder with psychosis. Schizophrenia-spectrum disorder was associated with family history of psychosis, cigarette smoking and variables indicating socioeconomic disadvantage. Victimization experiences were significantly related to affective psychoses and other non-affective psychoses. Around 80% of participants with any psychotic disorder sought some kind of professional help for mental health problems in the past year. Using comprehensive diagnostic assessment involving interview and record data, our results indicate that approximately 2.5% of Chinese adult population had lifetime psychotic disorder which represents a major public health concern.

Abstract
This meta-analysis examined the mean sleep duration and patterns in Chinese older adult population. A literature search was systematically conducted covering major English (PubMed, Embase and PsycINFO) and Chinese (Chinese National Knowledge Infrastructure (CNKI), WanFang and SinoMed) databases. Data in studies with the mean and standard deviation of sleep duration and/or the proportion of short and long sleep durations in Chinese older adults were extracted and pooled using random-effects models. Subgroup analyses were conducted according to gender, region, area, survey time and sample size. A total of 36 studies with 150,616 subjects were included for analyses. The pooled mean sleep duration of 21 studies with available data was 6.82 hours/day (95% CI: 6.59-7.05 hours/day). The estimated proportions of sleep duration <5 hours/day, <6 hours/day, <7 hours/day were 18.8% (95% CI: 1.7%-35.9%), 26.7% (95% CI: 19.7%-33.7%) and 42.3% (95% CI: 34.8%-49.8%), respectively. The pooled proportions for long sleepers were 22.6% (95% CI: 13.9%-31.4%) (>8 hours/day) and 17.6% (95% CI: 12.4%-22.9%) (>9 hours/day). Given the adverse effects of unhealthy sleep patterns, health professionals should pay more attention to sleep patterns in this population in China.

Abstract
The aim of this narrative review is to provide readers with a summary of the recent literature on women and schizophrenia and to address commonly asked questions about the role of gender in this illness. Important gender distinctions were found in the knowledge base around schizophrenia, particularly in the areas of symptom onset, hormonal and immune effects, and antipsychotic drug kinetics and their consequences. We also discuss and address commonly asked questions about gender and schizophrenia. This review concludes that gender differences influence the effectiveness of various treatments and need to be taken into account when planning comprehensive care services for individuals with schizophrenia.

Abstract
A novel molecular imprinting polymer (MIP) was prepared by bulk polymerization using sulpiride as the template molecule, itaconic acid (ITA) as the functional monomer and ethylene glycol dimethacrylate (EGDMA) as the crosslinker. The formation of the MIP was determined as the molar ratio of sulpiride-ITA-EGDMA of 1:4:15 by single-factor experiments. The MIP showed good adsorption property with imprinting factor α of 5.36 and maximum adsorption capacity of 61.13 μmol/g, and was characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and surface area analysis. With the structural analogs (amisulpride, tiapride, lidocaine and cisapride) and small molecules containing a mono-functional group (p-toluenesulfonamide, formamide and 1-methylpyrrolidine) as substrates, static adsorption, kinetic adsorption, and rebinding experiments were also performed to investigate the selective adsorption ability, kinetic characteristic, and recognition mechanism of the MIP. A serial study suggested that the highly selective recognition ability of the MIP mainly depended on binding sites provided by N-functional groups of amide and amine. Moreover, the MIP as solid-phase extractant was successfully applied to extraction of sulpiride from the mixed solution (consisted of p-toluenesulfonamide, sulfamethoxazole, sulfanilamide, p-nitroaniline, acetanilide and trimethoprim) and serum sample, and extraction recoveries ranged from 81.57% to 86.63%. The tentative tests of drug release in stimulated intestinal fluid (pH 6.8) demonstrated that the tablet with the MIP-sulpiride could obviously inhibit sulpiride release rate. Thus, ITA-based MIP is an efficient and promising alternative to solid-phase adsorbent for extraction of sulpiride and removal of interferences in biosample analysis, and could be used as a potential carrier for controlled drug release.

Abstract
This is the first meta-analysis of the pooled prevalence of insomnia in the general population of China. A systematic literature search was conducted via the following databases: PubMed, PsycINFO, EMBASE and Chinese databases (China National Knowledge Interne (CNKI), WanFang Data and SinoMed). Statistical analyses were performed using the Comprehensive Meta-Analysis program. A total of 17 studies with 115,988 participants met the inclusion criteria for the analysis. The pooled prevalence of insomnia in China was 15.0% (95% Confidence interval [CI]: 12.1%-18.5%). No significant difference was found in the prevalence between genders or across time period. The pooled prevalence of insomnia in population with a mean age of 43.7 years and older (11.6%; 95% CI: 7.5%-17.6%) was significantly lower than in those with a mean age younger than 43.7 years (20.4%; 95% CI: 14.2%-28.2%). The prevalence of insomnia was significantly affected by the type of assessment tools (Q = 14.1, P = 0.001). The general population prevalence of insomnia in China is lower than those reported in Western countries but similar to those in Asian countries. Younger Chinese adults appear to suffer from more insomnia than older adults. Trial Registration: CRD 42016043620

Abstract
The present study aimed to investigate the association of two polymorphisms (rs2844337 and rs11237200) in the P21 protein (cell division control protein 42/Rac)-activated kinase 1 gene with susceptibility to schizophrenia (SCZ) in Chinese Zhuang and Chinese Han populations. A total of 700 patients with SCZ and 700 healthy controls were recruited. Rs2844337 and rs11237200 polymorphisms were genotyped using Sequenom technology. A total of 591 patients completed the Positive and Negative Syndrome Scale (PANSS) assessment. Data were statistically analyzed using PLINK version 1.07 and SPSS version 17.0. In the Chinese Han population, the genotypic (P=0.038) and allelic (P=0.033) frequencies of the 3'-untranslated region (UTR) genetic variation of rs2844337 in patients were significantly decreased compared to that in controls; these frequencies were significantly associated with SCZ susceptibility in the additive model (Padj=0.032) and in the recessive model (Padj=0.031). Moreover, the TG haplotype constructed by rs2844337 and rs11237200 polymorphisms remained significantly associated with SCZ risk following adjustment for gender and age and applying a Bonferroni correction in the Chinese Han population (Padj=0.003, PBC=0.009). The adjacent 5'-UTR genetic variation of rs11237200 was significantly associated with the total score (Padj=0.006), positive scale score (Padj=0.014) and general psychopathology scale scores (Padj=0.009) in the recessive model of the Chinese Han population. However, these polymorphisms were not significantly associated with SCZ susceptibility or the PANSS scores in the Chinese Zhuang population. In conclusion, variations in the PAK1 gene influenced the susceptibility and severity of the clinical symptoms of SCZ in the Chinese Han population investigated in the present study.

Abstract
INTRODUCTION Second-generation antipsychotics show significant interpatient variability in treatment response and side-effect profiles, and the majority of patients with schizophrenia require multiple treatment changes. This subgroup analysis of the ESCAPE study evaluated the efficacy and safety of amisulpride in Chinese patients with schizophrenia who switched from risperidone or olanzapine. METHODS ESCAPE was a prospective, open-label, multicenter, single-arm Phase IV study in which Chinese patients with an ICD-10 diagnosis of schizophrenia received amisulpride for 8 weeks. This analysis included 109 patients who switched to amisulpride from risperidone (n=68) or olanzapine (n=41) and 59 treatment-naïve patients for reference. The primary effectiveness outcome was a ≥50% decrease in Positive and Negative Syndrome Scale (PANSS) Total score from Baseline to Week 8. The study was registered at ClinicalTrials.gov (NCT01795183). RESULTS Of the patients who switched from risperidone and olanzapine, 77.9% and 56.1% achieved ≥50% reduction in PANSS Total score from Baseline to Week 8 and 57.4% and 46.3% achieved ≥20% reduction in PANSS score from Baseline to Week 2, respectively; these end points were achieved by 66.1% and 61.0% of treatment-naïve patients, respectively. No unexpected adverse events (AEs) were reported. Of the most common AEs, extrapyramidal side effects occurred in 32.4% and 14.6%, blood prolactin increase in 32.4% and 39.0%, and ≥7% increase in body weight in 4.4% and 12% of patients switching from risperidone and olanzapine, respectively. CONCLUSION The results of this subgroup analysis suggest that switching to amisulpride from risperidone and olanzapine is effective and generally well tolerated in Chinese patients with schizophrenia.

Abstract
Schizophrenia is a common polygenetic disease affecting 0.5-1% of individuals across distinct ethnic populations. PGC-II, the largest genome-wide association study investigating genetic risk factors for schizophrenia, previously identified 128 independent schizophrenia-associated genetic variants (GVs). The current study examined the genetic variability of GVs across ethnic populations. To assess the genetic variability across populations, the 'variability indices' (VIs) of the 128 schizophrenia-associated GVs were calculated. We used 2504 genomes from the 1000 Genomes Project taken from 26 worldwide healthy samples comprising five major ethnicities: East Asian (EAS: n=504), European (EUR: n=503), African (AFR: n=661), American (AMR: n=347) and South Asian (SAS: n=489). The GV with the lowest variability was rs36068923 (VI=1.07). The minor allele frequencies (MAFs) were 0.189, 0.192, 0.256, 0.183 and 0.194 for EAS, EUR, AFR, AMR and SAS, respectively. The GV with the highest variability was rs7432375 (VI=9.46). The MAFs were 0.791, 0.435, 0.041, 0.594 and 0.508 for EAS, EUR, AFR, AMR and SAS, respectively. When we focused on the EAS and EUR population, the allele frequencies of 86 GVs significantly differed between the EAS and EUR (P<3.91 × 10-4). The GV with the highest variability was rs4330281 (P=1.55 × 10-138). The MAFs were 0.023 and 0.519 for the EAS and EUR, respectively. The GV with the lowest variability was rs2332700 (P=9.80 × 10-1). The MAFs were similar between these populations (that is, 0.246 and 0.247 for the EAS and EUR, respectively). Interestingly, the mean allele frequencies of the GVs did not significantly differ between these populations (P>0.05). Although genetic heterogeneities were observed in the schizophrenia-associated GVs across ethnic groups, the combination of these GVs might increase the risk of schizophrenia.

Abstract
Objective: Recent genome-wide association studies have identified a significant relationship between the NT5C2 variant rs11191580 and schizophrenia (SCZ) in European populations. This study aimed to validate the association of rs11191580 polymorphism with SCZ risk in a South Chinese Han population. The relationship of this polymorphism with the severity of SCZ clinical symptoms was also explored. Methods: A case-control study was performed in 462 patients with SCZ and 598 healthy controls. rs11191580 was genotyped by the Sequenom MassARRAY iPLEX platform. A total of 459 SCZ patients completed the Positive and Negative Syndrome Scale (PANSS) evaluation. Data were analyzed by PLINK software. Results: We confirmed an association of the rs11191580 polymorphism with SCZ risk in South Chinese Han under a dominant genetic model (ORadj = 0.769; 95%CIadj = 0.600-0.984; padj = 0.037). PANSS scores showed a significant association between variant rs11191580 and total score (padj = 0.032), lack of response scale score (padj = 0.022), and negative scale score (additive: padj = 0.004; dominant: padj = 0.016; recessive: padj = 0.021) after data were adjusted for age and sex. Conclusion: NT5C2 variant rs11191580 conferred susceptibility to SCZ and affected the clinical symptoms of SCZ in a South Chinese Han population.

Abstract
BACKGROUND Population-representative prevalence data for mental, neurological, and substance use disorders are essential for evidence-based decision making. As a background to the China-India Mental Health Alliance Series, we aim to examine the availability of data and report prevalence for the most common mental, neurological, and substance use disorders in China and India from the Global Burden of Disease study 2013 (GBD 2013). METHODS In this systematic analysis, data sources were identified from GBD 2013 for the prevalence of mental, neurological, and substance use disorders in China and India published up to Dec 31, 2013. We calculated the proportion of the population represented by the data with the adjusted population coverage (APC) method adjusting for age, sex, and population size. We developed prevalence models with DisMod-MR 2.0, a Bayesian meta-regression instrument used to pool population-representative epidemiological data as part of GBD 2013. We report estimates and 95% uncertainly intervals (95% UI) for 15 mental, neurological, and substance use disorders for China and India in 1990 and 2013, and benchmark these against those for other BRICS countries (Brazil, Russia, and South Africa) in 2013. FINDINGS Few population-representative data were found for the disorders, with an average coverage of 15% of the population of the Chinese mainland and 1% of the population of India. For men in both China and India, major depressive disorder, anxiety disorders, and alcohol dependence were the most common mental, neurological, and substance use disorders. Prevalence of major depressive disorder was 2·2% (95% UI 1·5-2·8) in Chinese men and 3·5% (2·4-4·6) in Indian men; prevalence of anxiety disorders was 2·0% (1·1-3·2) and 1·9% (1·2-2·3), respectively. For women, anxiety disorders, major depressive disorder, and dysthymia were the most common. Prevalence of major depressive disorder was 3·3% (2·3-4·1) in Chinese women and 4·7% (95% UI 3·3-6·2) in Indian women; prevalence of anxiety disorders was 3·3% (1·6-5·3) and 4·1% (3·3-5·0), respectively. Schizophrenia was more prevalent in China (0·5%, 95% UI 0·4-0·5) than in India (0·2%; 0·2-0·2). INTERPRETATION More data for mental, neurological, and substance use disorders are needed for India and China but the large population and geographic scale of these countries present challenges to population-representative data collection.

Abstract
Understanding the epidemiological profiles of mental, neurological, and substance use disorders provides opportunities for the identification of high-risk population subgroups and for the development of effective country-specific prevention and intervention strategies. Guided by the Conceptual Framework for Action on the Social Determinants of Health by WHO we reviewed the literature to examine the association between a range of social correlates (eg, sex, age, education, income, urbanicity, marital status, and regional differences) and mental, neurological, and substance use disorders in China and India, the most populous countries in the world. We looked for papers on mental, neurological, and substance use disorders with location identifiers and socioeconomic correlates published between 1990 and 2015 and our search found 65 relevant studies from China and 29 from India. Several association patterns between social correlates and mental, neurological, and substance use disorders were not consistent with those reported in high-income countries, including a high concentration of middle-aged men with alcohol use disorders in China and to a lesser extent in India, and a positive association between being married and depression among women in India. Consistent with previous global reports, low education and poverty were associated with higher occurrence of dementia in both China and India, although there is evidence of an interaction between education and income in the risk for dementia in China. Large variations across regions and ethnic groups were consistently documented in China. These unique correlation patterns for mental, neurological, and substance use disorders identified in China and India emphasise the importance of understanding the local social context when planning targeted strategies to reduce the burden of these disorders. High-quality, up-to-date information about the constantly changing pattern of societal factors correlated with mental, neurological, and substance use disorders is urgently needed to help reduce the large and increasing negative social and economic effects that these conditions are having in China, India, and other low-income and middle-income countries.

Abstract
BACKGROUND The aim of this study was to examine the prevalence of current smoking in male patients with schizophrenia in China. METHOD A systematic literature search was conducted from database inception until June 20, 2015 without language restrictions in PubMed, EMBASE, China National Knowledge Infrastructure (CNKI) and WanFang Database. Studies fulfilling the following criteria were included: (a) data available in male schizophrenia patients and (b) data available on current smoking status. Statistical analyses were performed with the Comprehensive Meta-Analysis program. RESULTS A total of 23 studies met eligibility criteria for the meta-analysis. The pooled prevalence of current smoking was 59.1% (95% Confidence interval [CI]: 53.3-64.7%). Current smoking was significantly more frequent in inpatients than in outpatients (61.3% vs. 48.2%, Q=7.5, P=0.006), and higher in chronic compared to first-episode patients (74.5% vs. 45.1%, Q=32.3, P=0.0001). Furthermore, using a median split, patients aged 38.2 years or older smoked more often than those aged below 38.2 years (65.8% vs. 52.3%, Q=6.4, P=0.01). There were no significant associations between prevalence of current smoking and definitions of smoking, study publication year, sample size and illness duration. CONCLUSIONS The pooled prevalence of current smoking of male patients with schizophrenia in China is lower compared to Western and other Asian countries. Possible relationships between lower prevalence of current smoking and psychopathology in patients with schizophrenia require further investigation.

Abstract
OBJECTIVE The aim of the study was to explore the efficacy of structural group therapy on the self-consistency and congruence of inpatient adolescents with a diagnosis of schizophrenia. METHOD Sixty inpatient adolescents with schizophrenia were randomly assigned to an intervention group (n = 30) and a control group (n = 30). The intervention group was provided with a 12-session structural group therapy program for six weeks (1 h, two times per week), while the control group participated in a handicraft group. All patients were assessed with the Self-Consistency and Congruence Scale (SCCS) and the Positive and Negative Syndrome Scale (PANSS) at pretest, posttest, three-month and one-year follow-up. The results were analyzed using t-test and repeated measures ANOVA. FINDINGS The two groups had no significant difference at the pre-test of outcome measures (p > 0.05). Significant differences existed between the two groups in ego-dystonic, self-flexibility, SCCS scores, positive syndrome, general psychopathology and PANSS scores after the intervention (p < 0.05). At the three-month follow-up, ego-dystonic, self-flexibility and PANSS scores were also found to be significantly different between the two groups (p < 0.05). But the outcome measures were not significantly different between the two groups at the one-year follow-up. CONCLUSION Structural group therapy in a mental health setting had a positive effect on improving self-consistency and congruence, positive symptoms and general psychopathology of inpatient adolescents with a diagnosis of schizophrenia.
