Objective:To investigate anxiety symptoms and associated factors in relocated elderly residents of new townships,and to provide evidence for prevention interventions.Methods:A cross-sectional study was conduc-ted in relocated elderly residents in new townships of three urban areas in Shandong Province from 2021 to 2023.The study instruments included Ascertain Dementia-8,Generalized Anxiety Disorder-7,self-administered de-mographic characteristics information questionnaire.Multivariate analysis of factors associated with anxiety symp-toms in elderly residents was performed using multivariate logistic regression.Results:The prevalence rate of mild anxiety symptoms was 5.8％,and the rate of moderate-to-severe anxiety symptoms was 1.3％in 3 313 resi-dents.Multivariate analysis found that self-assessed general psychological condition(OR=0.52),good family envi-ronment(OR=0.34),no self-perceived cognitive impairment(OR=0.31),no chronic diseases(OR=0.42),and only one chronic disease(OR=0.61)were protective factors for mild anxiety symptoms,and very good dietary structure(OR=2.15)and fair dietary structure(OR=2.39)were risk factors for those.Very good family environ-ment(OR=0.11)and average family environment(OR=0.16),and no self-perceived cognitive impairment(OR=0.14)were protective factors for moderate-to-severe anxiety symptoms,and 0-3 years(OR=3.24)and 4-6 years(OR=3.28)of relocation were risk factors for those.Conclusion:Family environment,dietary structure,and duration since relocation are key factors associated with anxiety symptoms among relocated elderly residents in new townships.Targeted interventions should be implemented to address their mental health needs.

Objective:To explore the association between perceived social support,TMEM161B gene rs768705 polymorphism,and their interaction with incidence of depressive symptoms in the freshmen.Methods:A total of 9928 freshmen from two medical universities were investigated at baseline and follow-up two years later during 2018-2020 by cluster sampling.A self-report demographic characteristics questionnaire was used to collect information of general demographic characteristics.Perceived Social Support Scale,Beck Depression Inventory,Beck Anxiety Inventory and Adolescent Self-Rating Life Events Check List were used to measure the level of perceived social support,depressive symptoms,anxiety symptoms and the number of negative life events of individuals.Blood sam-ples were collected and typed for DNA by professionals.Results:Family support and other support were all nega-tively associated with depressive symptoms in the freshmen(OR=0.96,95％CI:0.93-0.99;OR=0.94,95％CI:0.91-0.98).There was no correlation between friend support and depressive symptoms in the freshmen(OR=0.99,95％CI:0.95-1.02).TMEM161B gene rs768705 polymorphism(AG)was positively associated with de-pressive symptoms in the freshmen(OR=1.58,95％CI:1.12-2.23).The interactions of friend support with TMEM161B gene rs768705 polymorphism(AG)(OR=1.13,95％CI:1.02-1.26)and other support with TMEM161B gene rs768705 polymorphism(AG)(OR=1.13,95％CI:1.02-1.25)had significant effects on the incidence of depressive symptoms in the females and no significant effect in the males.Conclusion:The perceived social support,TMEM161B gene rs768705 polymorphism and their interaction are associated with influence of de-pressive symptoms,and have sex difference in the freshmen.

Objective:To investigate the impact of traumatic experiences on panic attack,depression and anxi-ety symptoms among community residents.Methods:Totally 11 280 community residents were recruited.The Com-posite International Diagnostic Interview-3.0,Patient Health Questionnaire,7-item Generalized Anxiety Disorder Scale and general information questionnaire were used for face-to-face interview to collect information.Propensity Score Matching was conducted to match 5 184 community residents for analysis.Logistic regression was employed to analyze the impact of traumatic events on panic attack,depressive symptoms,and anxiety symptoms among the study sample.Results:Traumatic events were associated with a higher likelihood of experiencing panic attack(OR=3.26,95％CI:2.26-4.70),depression symptoms(OR=1.92,95％CI:1.56-2.37)and anxiety symptoms(OR=1.57,95％CI:1.24-1.99).Conclusion:Traumatic events extensively impact the mental health of commu-nity residents.Timely psychological support and early intervention are essential to prevent mental health issues in community residents affected by trauma.

Objective:To describe the prevalence of anxiety disorders and its distribution in Inner Mongolia Autonomous Region,and to explore the relevant factors of anxiety disorders.Methods:From June 2019 to Decem-ber 2019,representative multi-stage disproportionate stratified sampling procedure was used to sample in residents aged 18 and over in the Inner Mongolia Autonomous Region.All respondents were face-to-face interviewed by trained interviewers.Composite International Diagnostic Interview-3.0(CIDI-3.0)was used to diagnose anxiety disorders according to the criteria and definition of the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ).Chi-square test and multivariate logistic regression analysis were used for statistical anal-ysis.Results:Totally 12 315 people were interviewed in the survey.The weighted 12-mouth prevalence rate of any anxiety disorder was 4.64％,and the lifetime prevalence rate was 6.25％.The weighted 12-month prevalence rate of anxiety disorders was higher in female than that in male(5.38％vs.3.92％).The rate was higher in rural resi-dents than that in urban residents(5.67％vs.3.95％).The rate was higher in people with chronic diseases than that in people without chronic diseases(6.81％vs.2.29％).Logistic regression analysis showed that unmarried(OR=2.32,95％CI:1.31-4.10),separated/divorced(OR=2.49,95％CI:1.33-4.67),in debt(OR=1.55,95％CI:1.04-2.32),chronic disease(OR=2.22,95％CI:1.39-3.53),family history of anxiety disorders(OR=12.05,95％CI:8.78-16.53),poor sleep(OR=2.64,95％CI:1.97-3.54)were risk factors of occurrence of anxiety disorders,while junior high school(OR=0.65,95％CI:0.44-0.96)was protective factor of anxiety disor-ders.Conclusion:Adults with chronic diseases,poor sleep,unmarried or separated/divorced,family history of anxi-ety disorders,and financial debt are at higher risk groups of anxiety disorder in Inner Mongolia Autonomous Re-gion.

Objective:To explore relationships and differences of perceived social support and depression-anx-iety symptoms between rural-to-urban migrated residents and rural residents.Methods:A total of 5 958 rural-to-ur-ban migrated residents and 4 720 rural residents were recruited.The Patient Health Questionnaire-9,Generalized Anxiety Disorder-7,and Perceived Social Support Scale were used to assess symptoms of depression,anxiety,and social support,respectively.Network estimation,centrality and predictability measurement,accuracy and stability verification,and network comparison were conducted based on R 4.2.0 to compare the network structure differ-ences between the two groups of residents.Results:In rural-to-urban migrated residents,"lack of energy"in depres-sive symptoms and"inability to control worry"in anxiety symptoms were the nodes with the highest expected influ-ence(EI).In rural residents,"low self-evaluation"in depressive symptoms and"difficulty relaxing"in anxiety symptoms were the nodes with the highest EI.The highest node of perceived social support EI for both groups was"support from relatives/leaders."The bridge nodes were the same for rural-to-urban migrated residents and rural residents,with"be down in spirits"being the nodes with the highest bridge expected influence.The results of net-work comparison test showed that the overall network structure of rural-to-urban migrated residents and rural resi-dents was statistically different(P＜0.05).Conclusion:There are correlation and difference among depressive symptoms,anxiety symptoms,and perceived social support in rural-to-urban migrated and rural residents.

Objective:To explore associated factors of post-discharge depressive symptom severity in patients with bipolar disorder.Methods:A longitudinal follow-up was conducted to investigate the demographic,behavioral,and clinical characteristics,and social function among discharged patients with bipolar disorder who met the DSM-5 diagnostic criteria.Clinical characteristics were assessed with the Hamilton Depression Scale(HAMD)and Brief Psychiatric Rating Scale(BPRS).Single factor and multivariate regression were carried out to explore the associat-ed factors of depressive symptom severity in patients with bipolar disorder.Results:A total of 298 discharged pa-tients with bipolar disorder were face-to-face interviewed to complete the follow-up survey.At follow-up time,psy-chotic symptoms(standardized(β)=0.18),housework((β)=0.23),social interaction((β)=0.17)and BPRS total score((β)=0.46)were positively associated with HAMD total score.Productive labor and work((β)=-0.27)and person-al life management((β)=-0.15)were negatively associated with HAMD total scores.Conclusion:Post-discharge depressive symptom severity in bipolar disorder patients is influenced by multiple factors.Effective management of psychotic symptoms,combined with enhanced community-based social rehabilitation and functional recovery,may help reduce the persistence or worsening of depressive symptoms and improve prognosis.

Objective:To explore the risk factors of suicidal ideation in community residents in Shandong province,China,and to establish a prediction model and a nomogram for the risk of suicidal ideation.Methods:To-tally 11 087 community residents in Jining City,Zoucheng City,and Weifang City,Shandong Province,were recrui-ted as the study subjects.The general information questionnaire,Composite International Diagnostic Interview-3.0,General Anxiety Disorder-7,were used to collect demographic information,mental health status,family information,and lifestyle using a computer-assisted interview system to conduct face-to-face interview.LASSO regression and binary logistic regression analyses were used to develop a nomogram model of the risk of suicidal ideation.Results:Young people,female,smoking,non-new town residents,no physical exercise,difficulty approaching people,anxiety symptoms and depression were effective predictors of suicidal ideation.The area under the curve(AUC)of the training set(AUC)was 0.89(95％CI:0.85-0.93)and AUC of the validation set(AUC)was 0.83(95％CI:0.75-0.92).Conclusion:The nomogram prediction model constructed in this study on suicidal ideation in com-munity residents has a high degree of differentiation and accuracy.It could be used to screen people at high risk of suicide and provide intervention to suicidal ideation in community residents.

Objective:To explore the effect of different types of social activity participation on self-rated men-tal health disparity between urban and rural older adults in China.Methods:The study data was sourced from the 2018 wave of Chinese General Social Survey(CGSS).Factor analysis was applied to divide social activities into three dimensions:entertainment activities,cultural activities,family and friend gatherings.Logistic regression model was adopted to analyze the effect of social activity on self-rated mental health.Fairlie decomposition model was ap-plied to explore the effect of social activity on urban-rural disparity in self-rated mental health.Results:The self-ra-ted good mental health proportion of urban old persons(n=3 139)was 72.0％,which was higher than that of rural old persons(n=1 549)(53.7％)(P＜0.001).Recreational activities and gatherings of friends and relatives sig-nificantly improved self-rated mental health in urban and rural old persons.Fairlie decomposition result revealed that approximately 18.7％of self-rated mental health disparity could be attributed to urban-rural disparity in entertain-ment activities.Moreover,urban-rural disparity in family and friends gatherings could explain about 3.9％of the disparity.Conclusion:Urban older adults have better mental health than their rural counterparts.Furthermore,social activity is beneficial to mental health for both urban and rural older adults.Urban-rural disparity in entertainment ac-tivities make an important contribution to mental health disparity between urban and rural older adults.

Objective:To describe the prevalence and distributions of mood disorder in Inner Mongolia Au-tonomous Region,and analyze the related risk factors.Methods:The multistage stratified sampling method with un-equal probability was used to select permanent residents aged 18 years and over in Inner Mongolia Autonomous Re-gion.The Composite International Diagnostic Interview 3.0 was used as a diagnostic tool.Mood disorders were di-agnosed according to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM-Ⅳ).Single and multivariate analyses were used to investigate the related factors of mood disorders.Results:Totally,12 315 community residents were interviewed in the survey.The weighted 12-month prevalence and lifetime prevalence of mood disorder were 5.4％and 8.7％,respectively.Weighted 12-month prevalence of depressive disorder was 4.9％,and that of bipolar disorder was 0.3％.Among all subtypes of mood disorder,the 12-month prevalence rate of major depressive disorder(3.1％)was the highest.Multivariate logistic regression analysis showed that female,unmarried,separated or divorced,unemployment,family history,other mental disorders,sleep disorders and chronic diseases(OR=1.56,2.80,2.07,1.42,13.46,7.97,3.23,2.13)were risk factors of mood disorder,while aged 65 years and over(OR=0.44)was protective factor of mood disorders.The lifetime consultation rate in patients with mood disorders was 15.5％,the rate of psychiatric consultation was 3.7％,the rate of medication was 1.8％.Con-clusion:It indicates that female residents and people who are unmarried,separated and divorced,unemployed,with family history,suffering from other mental disorders,suffering from sleep disorders,and suffering from chronic dis-eases may be high risk groups of mood disorders,and the utilization rate of health services is rather low in Inner Mongolia Autonomous Region.
