Meta-analysis of the prevalence of anxiety disorders in mainland China from 2000 to 2015

Alterations in neural circuit dynamics between the limbic network and prefrontal/default mode network in patients with generalized anxiety disorder

BACKGROUND

Widespread functional alterations have been implicated in patients with generalized anxiety disorder (GAD). However, most studies have primarily focused on static brain network features in patients with GAD. The current research focused on exploring the dynamics within functional brain networks among individuals diagnosed with GAD.

METHODS

Seventy-five participants were divided into patients with GAD and healthy controls (HCs), and resting-state functional magnetic resonance imaging data were collected. The severity of symptoms was measured using the Hamilton Anxiety Scale and the Patient Health Questionnaire. Co-activation pattern (CAP) analysis, centered on the bed nucleus of the stria terminalis, was applied to explore network dynamics. The capability of these dynamic characteristics to distinguish between patients with GAD and HCs was evaluated using a support vector machine.

RESULTS

Patients with GAD exhibited disruptions in the limbic-prefrontal and limbic-default-mode network circuits. Particularly noteworthy was the marked reduction in dynamic indicators such as occurrence, EntriesFromBaseline, ExitsToBaseline, in-degree, out-degree, and resilience. Moreover, these decreased dynamic features effectively distinguished the GAD group from the HC in this study.

CONCLUSIONS

The current findings revealed the underlying brain networks associated with compromised emotion regulation in individuals with GAD. The dynamic reduction in connectivity between the limbic-default mode network and limbic-prefrontal networks could potentially act as a biomarker and therapeutic target for GAD in the future.

Curative care expenditure of outpatient anxiety disorder in Liaoning Province, 2015-2020-based on "System of Health Accounts 2011"

Introduction

Anxiety disorders are the most common mental disorder, experienced by more than a quarter of the population. This study examines total outpatient curative care expenditures (CCE) for anxiety disorders and changes in their composition based on the System of Health Accounts 2011 (SHA 2011).

Methods

This study used multi-stage stratified random from a total of 9,318,513 outpatient sample data by 920 healthcare organizations, a total of 109,703 cases of anxiety disorders from 53 sample organizations (5.76%) from 2015 to 2020. Univariate analysis, multifactor analysis and structural equation modeling (SEM) were used to explore the influential factors affecting outpatient CCE for anxiety disorders.

Results

Anxiety disorder outpatient CCE from 2015 to 2020 continued to increase from CNY 99.39million in 2015 to CNY 233.84 million in 2020, mainly concentrated in western medicine costs, 15-64 years, general hospital, generalized anxiety disorder and public financing. The results of univariate analysis showed statistically significant differences in all subgroups, and the results of multivariate analysis and SEM showed that the choice to purchase western drugs, purchase prepared Chinese drugs, choice to have a checkup, urban employees' basic medical insurance, and 0-14 years old were associated with high anxiety disorder outpatient CCE.

Conclusion

Initiatives to improve the essential drug system, reduce the out-of-pocket (OOP) ratio, and strengthen primary health care to effectively reduce the medical burden on patients.

Prevalence of the generalized anxiety disorder in Tunisia: A study of 707 primary care outpatients

OBJECTIVE

This study examined the prevalence and correlates of generalized anxiety disorder (GAD) among primary care outpatients.

METHOD

A multicenter, cross-sectional study was conducted that included 707 primary care outpatients being seen at 20 primary healthcare centers in Tunis and Sfax, Tunisia. The Mini International Neuropsychiatric Interview was used to identify a diagnosis of GAD. The Beck Depression Inventory was used to assess depressive symptom severity, and the Sheehan Disability Scale (SDS) was used to measure functional impairment.

RESULTS

The prevalence of GAD was 11%. GAD was positively correlated with female gender (P = .005), family history of psychiatric disorder (P < .001), personal history of suicide attempt (P = .019), and depressive symptoms (P < .001). Based on the SDS, severe to very severe functional limitations were reported at work, in social life, and family life (56.4%, 60.2%, and 73.1%, respectively) among GAD patients.

CONCLUSION

This study indicated a relatively high prevalence of GAD among primary care patients in Tunisia. Risk factors were also determined that may help to identify these patients. This information may help primary care physicians recognize this diagnosis and provide timely referrals to mental health professionals to prevent complications and preserve quality of life.

Integrating EEG and Ensemble Learning for Accurate Grading and Quantification of Generalized Anxiety Disorder: A Novel Diagnostic Approach

Current assessments for generalized anxiety disorder (GAD) are often subjective and do not rely on a standardized measure to evaluate the GAD across its severity levels. The lack of objective and multi-level quantitative diagnostic criteria poses as a significant challenge for individualized treatment strategies. To address this need, this study aims to establish a GAD grading and quantification diagnostic model by integrating an electroencephalogram (EEG) and ensemble learning. In this context, a total of 39 normal subjects and 80 GAD patients were recruited and divided into four groups: normal control, mild GAD, moderate GAD, and severe GAD. Ten minutes resting state EEG data were collected for every subject. Functional connectivity features were extracted from each EEG segment with different time windows. Then, ensemble learning was employed for GAD classification studies and brain mechanism analysis. Hence, the results showed that the Catboost model with a 10 s time window achieved an impressive 98.1% accuracy for four-level classification. Particularly, it was found that those functional connections situated between the frontal and temporal lobes were significantly more abundant than in other regions, with the beta rhythm being the most prominent. The analysis framework and findings of this study provide substantial evidence for the applications of artificial intelligence in the clinical diagnosis of GAD.

Decomposition and comparative analysis of depressive symptoms between older adults living alone and with others in China

Objective

This research dealt with investigating and measuring the contribution of the factors that impact depression in older adults living alone vs. those living with others (hereafter referred to as "not alone") in China.

Design

This investigation adopts a cross-sectional research design. The dataset employed for this study comprises data from 2018 the Chinese Longitudinal Health Longevity Survey (CLHLS).

Setting

The research involved data sourced from China, specifically from 23 of its provinces. From the 8th CLHLS, 12,197 older adults were selected who met the study requirements.

Measures

Binary logistic regression models were established to delve into the primary factors impacting the depressive symptoms of the individuals. Furthermore, Fairlie models were employed to assess these factors between older adults living alone and those not living alone. This approach facilitated an in-depth analysis of their respective contributions.

Results

It was observed that the demographic of Chinese older adults exhibited depressive symptoms at a rate of 11.92%. Older adults who resided alone (15.76%) exhibited a higher prevalence of depressive symptoms in comparison to their counterparts living in not-alone settings (11.15%). Employing Fairlie decomposition analysis, it was determined that this observed disparity in depressive symptoms, amounting to 55.33% of the overall difference, could be primarily attributed to distinct factors. This encompassed variance in marital status (20.55%), years of school (4.63%), self-reported local income status (7.25%), self-reported sleep status (17.56%), and self-reported health status (4.24%).

Conclusion

The resulting data indicated that depressive symptoms exhibited an elevated prevalence in older adults living alone than in those living not alone. This discrepancy was predominantly attributed to variance in socioeconomic marital status, years of school, self-reported local income status, self-reported sleep status, and self-reported health status by living alone vs. not alone. Mitigating these influential factors could help develop targeted and meticulous intervention strategies, precisely tailored to improve the mental well-being of older adults at high risk.

Serum BDNF levels and state anxiety are associated with somatic symptoms in patients with panic disorder

Background

We aimed to explore the predictive role of serum BDNF and anxiety-related variables in changes in somatic symptoms post-escitalopram treatment in panic disorder (PD) patients.

Methods

Ninety PD patients and 99 healthy controls (HCs) were enrolled. PD patients received an 8-week escitalopram treatment. All patients were administered the Panic Disorder Severity Scale-Chinese Version (PDSS-CV) and State-Trait Anxiety Inventory (STAI) to assess panic and anxiety-related symptoms, respectively. Patient Health Questionnaire 15-item scale (PHQ-15) was performed to measure somatic symptoms, and the blood sample was collected to detect serum BDNF levels in all participants. We performed partial correlation analysis and multiple linear regression to explore correlates of PHQ-15 and predictors of PHQ-15 changes post-escitalopram treatment after controlling for age, gender, education levels (set as a dummy variable), the current duration, comorbid AP, and/or GAD.

Results

Compared to HCs, PD patients had lower serum BDNF levels and higher PHQ-15 scores that could be improved post-escitalopram treatment. Lower baseline STAI state (b = -0.07, p = 0.004), and PDSS-CV scores (b = -0.25, p = 0.007), but higher baseline serum BDNF levels (b = 0.35, p = 0.007) contributed to the prediction of PHQ-15 changes post-escitalopram treatment.

Conclusion

State anxiety, serum BDNF levels, and panic severity could predict changes in somatic symptoms post-escitalopram treatment, our results highlighted that serum BDNF could serve as a biological indicator for improving somatic symptoms in PD patients.

Prevalence and severity of anxiety and depression in Chinese patients with breast cancer: a systematic review and meta-analysis

Context

Anxiety/depression in breast cancer (BC) is common around the world, and Chinese BC patients should not be ignored. The prevalence of anxiety and depression among BC patients are various in different regions of China, but no clear summarization has been made.

Purpose

This meta-analysis aimed to evaluate the prevalence and severity of anxiety and depression among breast cancer (BC) patients in China.

Methods

A literature search on PubMed, Web of Science, Embase, CINAHL, Scopus, PsycINFO, Cochrane database library, CNKI, Wanfang, and SinoMed was conducted up to 29 December 2021. The effect size (ES) or standard mean difference (SMD) and the corresponding 95% confidence intervals (CIs) for the prevalence and severity of anxiety/depression were calculated using the STATA 12.0 software.

Results

A total of 63 identified studies were included, containing a total of 53,513 Chinese women confirmed breast cancer. The results showed a high pooled prevalence of anxiety (38%, 95% CI, 27-50%, I² = 99.4%, p < 0.001) and depression (38%, 95% CI, 33-44%, I² = 99.2%, p < 0.001) among Chinese BC patients. Moreover, both anxiety (SMD = 0.30, 95% CI, 0.08-0.53, I² = 91.6%, p < 0.001) and depression (SMD = 0.25, 95% CI, -0.05-0.55, I² = 95.3%, p < 0.001) in BC patients were more serious than those in healthy controls, but not significantly different from patients with other diseases. Specifically, among the six regions included, the prevalence of anxiety and depression were both the highest in Northeast China, obviously superior than the second-highest region.

Conclusion

The study showed high levels of anxiety and depression among BC patients in China, especially those in the northeast. Clinicians and researchers should pay attention to the psychological problems of patients with breast cancer and regard it as one of the important prognostic outcomes of patients.

Problem Solving and Emotion Coping Styles for Social Anxiety: A Meta-analysis of Chinese Mainland Students

Studies of how positive and negative coping styles affect social anxiety show mixed results. Hence, our two meta-analyses determined the overall effect sizes of problem solving-focused coping (PSC) styles and emotion-focused coping (EFC) styles on social anxiety in mainland China (PSC: k = 49 studies, N = 34,669; EFC: k = 52, N = 36,531). PSC was negatively linked to social anxiety (- .198), and EFC was positively linked to social anxiety (.223). In years with more national income, PSC's and EFC's effect sizes were larger. PSC's effect sizes were smaller among rural students (vs. urban students), larger among older students (university, high school, middle school), and larger in cross-sectional (vs. longitudinal) studies. When using SAD (vs. others) social anxiety measures, PSC effect sizes were larger, but EFC effect sizes were smaller. EFC effect sizes were larger in studies with convenience (vs. representative) samples. Gender, single child status, and coping style measurement showed no moderation effects. These findings suggest that using problem solving-focused coping styles rather than emotion-focused may reduce social anxiety, so future experimental studies can test this idea more rigorously.

Perceived Risk of COVID-19 and Anxiety in Syrian Refugees in Turkey

Pandemics are amongst the most destructive disasters to have afflicted humankind through history. These disasters entail a disproportionate effect on refugee populations, who are already in a state of high vulnerability. This study aims to assess the perception of risk of COVID-19 in the refugee populations in Turkey, in addition to evaluating anxiety levels during the pandemic. The participants of this study were refugees enrolled in a local nonprofit organization in Istanbul. They were asked to complete questionnaires which asked about COVID-19 and any self-protection measures. The questionnaire also incorporated the General Anxiety Disorder-7 screening test. In this young, male and mostly unemployed population, knowing someone who experienced COVID-19 was associated with a greater likelihood of compliance with hygiene and physical distancing measures. Anxiety levels were above 29%, and the highest scores were in the age group between 25 and 55 years. We argue that comprehensive public health measures against COVID-19 should include focused interventions for refugee populations that take the extra vulnerability (health, financial, and other) into account.

Peer attachment and self-esteem mediate the relationship between family function and social anxiety in migrant children in China

BACKGROUND

Social anxiety is a frequently reported symptom in children and adolescents. The literature suggests that family function is related to symptoms of social anxiety in children. However, relatively little is known about the potential mechanisms underlying the relationship between family function and social anxiety. Thus, the purpose of the present study is to examine the roles of peer attachment and self-esteem in the relationship between family function and social anxiety in a sample of migrant children in China.

METHODS

A total of 437 participants (54.9% male; meanage  = 10.87 years) were selected from two public schools of migrant children in two areas of Hangzhou and Jiaxing, the major labor-importing cities in China, in May 2016. All participants completed four questionnaires assessing family function, peer attachment, self-esteem, and social anxiety.

RESULTS

The results showed that family function was bivariately and significantly related to symptoms of social anxiety. Additionally, self-esteem fully mediated the relationship between family function and social anxiety peer attachment. Moreover, the relationship between family function and social anxiety was fully mediated by peer attachment and self-esteem (in that order).

CONCLUSIONS

Peer attachment and self-esteem serve as critical pathways linking family function and social anxiety. Thus, tailored interventions should consider the roles of peer attachment and self-esteem to alleviate symptoms of social anxiety in migrant children.

The Relationship Between Psychological Flexibility and Depression, Anxiety and Stress: A Latent Profile Analysis

Purpose

To explore the potential classification of psychological flexibility (PF) among Chinese college students, analyze whether there is group heterogeneity in PF, and discuss the differences in the latent profile of PF in the negative emotions of depression, anxiety, and stress.

Methods

A total of 1769 college students were investigated using the Psychological Flexibility Questionnaire and Depression-Anxiety-Stress Self-rating Scale, and heterogeneity was tested by latent profile analysis.

Results

The PF of college students can be divided into three latent profiles: self-contradiction group (19.2%), high PF group (34.1%), and low PF group (46.7%). The scores of depression, anxiety, and stress are significantly different among the groups.

Conclusion

There is obvious group heterogeneity in the PF of college students, and they can be divided into the self-contradiction group, the high PF group, and the low PF group. The self-contradiction and low PF groups score significantly higher on the negative emotions of depression, anxiety, and stress than the high PF group.

Effect of resistance training on heart rate variability of anxious female college students

Introduction

Female college students are a group with high incidence of anxiety, and anxiety will lead to the disorder of autonomic nervous system (ANS), which will adversely affect their study and life. Resistance training plays a positive role in improving anxiety, but there is little evidence on whether resistance training can improve ANS of anxious female college students. Heart rate variability (HRV) has gained widespread acceptance in assessing ANS modulation. Therefore, the objective of this study aimed to investigate the effects of resistance training on heart rate variability (HRV) in anxious female college student.

Methods

A randomized controlled study of resistance training intervention was conducted in 27 anxious female college students that assigned randomly into an intervention group (n = 14) and a control group (n = 13). The intervention group was intervened by cluster training for 8 weeks. Self-rating anxiety scale (SAS) was used. ANS is evaluated by short-term HRV. Muscle strength was assessed by 1 RM indirect method. Independent-sample t-test was used to test post-test-pre-test scores between the intervention and control groups.

Results

After the intervention, SAS score of the intervention group was significantly decreased (P < 0.05), SDNN of the intervention group was significantly increased (P < 0.05) and LF/HF was significantly decreased (P < 0.05).

Conclusion

The resistance training intervention adopted in this study significantly increased the HRV of anxious female college students and improved their autonomic nervous disorder.

Gender differences in association of urbanization with psychological stress in Chinese adults: A population-based study

Objective

To investigate the gender-specific associations between exposure to urbanization and psychological stress in China experiencing rapid urbanization.

Methods

Data were obtained from the 2015 China Health and Nutrition Survey. A total of 4,388 men and 5,098 women aged at least 18 years were obtained from 288 communities across 12 provinces and municipalities. Tertiles of the urbanization index, summarizing 12 urbanization dimensions at the community level, were used to define low, medium, and high levels of urbanization. The psychological stress was measured based on the 10-item Perceived Stress Scale. The gender-stratified multilevel analysis (Level-1: Individuals, Level-2: Communities, and Level-3: provinces/municipalities) was used to estimate the association between exposure to urbanization and psychological stress.

Results

After controlling for age, education status, marital status, work status, household income per capita, current smoking, alcohol drinking, sleep duration, BMI, and chronic conditions, the urbanization index was negatively associated with psychological stress in women (P _trend = 0.017) but not men (P _trend = 0.476). More specifically, a one-standard deviation increase in the score of community population density (β = -0.329, P = 0.329), modern markets (β = -0.247, P = 0.044), education (β = -0.448, P = 0.002), and housing (β = -0.380, P = 0.005) was negatively associated with psychological stress only in women, separately.

Conclusion

Our data revealed that living in the most urbanized communities is associated with lower levels of psychological stress for women but not men. Thus, this study can help empower decision-makers to accurately target vulnerable communities and plan effective strategies to address psychological outcomes.

Clinical efficacy and safety of low-dose doxepin in Chinese patients with generalized anxiety disorder: A before-after study

Clinical and animal studies have reported that low-dose doxepin may have positive effects on generalized anxiety disorder (GAD); however, its effectiveness and clinical safety are less well understood. This study is a before-after study and aims to investigate the effectiveness and side effects of low-dose doxepin by evaluating Hamilton Anxiety Scale (HAMA) scores, hormones, blood glucose, serum lipids, body weight, and body mass index (BMI) in patients with GAD. Forty-nine patients (20 males and 29 females) with GAD were randomly assigned to receive low-dose doxepin (6.25 mg-12.5 mg per day) for 12 weeks between February 2015 and March 2016. HAMA scores, fasting blood glucose (FBG) body weight, BMI, and some serum biochemical indexes, such as adrenocorticotropic hormone (ACTH), free triiodothyronine (FT3), total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDLC), and FBG, were assessed during pretreatment and post-treatment. Mean scores of HAMA decreased from 19.50 ± 1.22 to 8.50 ± 3.61 after low-dose doxepin treatment (P < .01). The serum levels of ACTH (4.33 ± 2.14 vs 6.12 ± 3.02 pmol/L), FT3 (4.78 ± 0.51 vs 5.15 ± 0.52 pg/mL), TC (4.55 ± 1.01 vs 5.93 ± 1.66 mmol/L), TG (1.69 ± 1.51 vs 3.39 ± 2.86 mmol/L), and LDLC (2.43 ± 0.88 vs 3.76 ± 1.25 mmol/L), and FBG (5.06 ± 0.43 vs 5.78 ± 0.81 mmol/L) were higher than that pretreatment with a significant difference (P < .01). Bodyweight (62.00 ± 7.45 vs 64.00 ± 6.44 kg, P = .23) and BMI (23.70 ± 2.35 vs 24.48 ± 2.11 kg/m2, P = .14) had no difference after treatment. These results suggest that low-dose doxepin has beneficial clinical efficacy and safety. Low-dose doxepin can ameliorate anxiety in GAD patients and has some effects on neuroendocrine systems and the metabolic activity of serum glucose and lipid.

Anxiety symptoms in older Chinese adults in primary care settings: Prevalence and correlates

Background

Integrating mental health services into primary care is a potentially cost-effective way to decrease the treatment gap for anxiety in older adults but data on the epidemiology of anxiety symptoms in older Chinese adults in primary care settings have been very limited. This study investigated the prevalence and correlates of anxiety symptoms in Chinese older primary care patients.

Methods

A total of 753 older primary care patients (≥65 years) were consecutively recruited from 13 primary care clinics in Wuhan, China, and interviewed with the validated Chinese version of the short form of the Geriatric Anxiety Inventory (GAI-SF).

Results

The prevalence of anxiety symptoms (GAI-SF ≥ 3) in older primary care patients was 21.1%. Statistically significant correlates of anxiety symptoms were female sex (vs. male, OR = 1.85, P = 0.002), poor economic status (vs. good, OR = 2.31, P = 0.013), fair and poor family relationship (vs. good, OR = 1.85, P = 0.006), hypertension (OR = 2.01, P < 0.001), chronic gastric ulcer (OR = 6.82, P < 0.001), and Parkinson's disease (OR = 7.83, P = 0.031).

Conclusions

Anxiety symptoms are prevalent among older adults attending primary care clinics. Efforts for preventing or reducing anxiety symptoms in older primary care patients may be more useful to target those who are women, have poor financial status, don't have a good family relationship, suffer from hypertension, have chronic gastric ulcer, and suffer from Parkinson's disease.

The Moderation Role of Neuroticism for Anxiety among Burdened Dementia Caregivers: A Study on Care Giver-Recipient Dyads

Caregiving burden proves to be a risk factor of anxiety disorders and anxiety affection. The current study investigates how an endogenous personality dimension - neuroticism - moderates the association between caregiving burden and anxiety affection. Between 2015 and 2017, the study deployed a cross-sectional survey of 674 (response rate = 89%) older adults who were hospitalized for dementia at two hospitals. From all primary caregivers of these patients, 661 agreed to participate in the survey which yielded 661 matched dyads as the final sample. Caregiving burden, neuroticism, and anxiety affection were each measured by established assessment instruments. We employed multivariate OLS regression to test the moderator and regressor effects. We found that care burden is a significant risk factor of higher levels of anxiety affection (β = .17, p < .001), and accounts for 4.6% of the variance in anxiety. Neurotic personality is also significantly associated with a greater level of anxiety (β = .26, p < .001). Neurotic personality moderates the association between anxiety and care burden (β = .24, p < .001). Our findings suggest that social and healthcare workers should assess caregiver personality and burden as well as provide support, resources, and coping strategies to those with neurotic personality traits or high care burden in an effort to reduce anxiety among caregivers.

The Relationship between Social Support and Anxiety among Rural Older People in Elderly Caring Social Organizations: A Cross-Sectional Study

BACKGROUND

Social support and anxiety have a major impact on later life quality in rural, older people in elderly caring social organizations (SOs). This study aimed to explore the relationship between social support and anxiety and their relevant influential factors among rural older people in elderly caring SOs in Anhui Province, China.

METHODS

This cross-sectional study was conducted through a multi-stage stratified cluster random sampling method. Independent t-tests, one-way ANOVA, Mann-Whitney U test, Kruskal-Wallis H test, and a generalized linear model were employed.

RESULTS

A significantly negative association between friends' support and anxiety were found among rural older people in elderly caring SOs. Statistically significant relationships were found between social support and gender, marital status, education level, whether visited by relatives, and institutional satisfaction. Similarly, anxiety was associated with gender, institutional satisfaction, comorbid chronic diseases, and friends' support.

CONCLUSIONS

Social support from friends plays an important role in preventing and regulating anxiety among rural older people, especially those from elderly caring SOs. To reduce the occurrence and level of anxiety among rural elderly in elderly caring SOs, an effort should be given to strengthening social support, improving institutional satisfaction, and emphasizing comorbid chronic diseases.

Relationships of Illness Perceptions with Depression and Anxiety in People Who Live with HIV/AIDS in a High-prevalence Ethnic Autonomous Region of Sichuan, China

Poor mental health challenges outcomes and treatment of people living with HIV/AIDS (PLWHA) and may be related to illness perceptions. To investigate if depression and anxiety were associated with illness perceptions, we drew a random sample of 729 PLWHA from 13 administrative units in Liangshan Prefecture, Sichuan, China. Among the PLWHA surveyed, 222 and 175 had probable anxiety or depression. In mixed-effects logistic regression, negative illness perceptions were associated with increased odds of anxiety/depression. In linear mixed-effects quantile regression, the relationship of more negative illness perceptions with more severe and frequent symptoms of anxiety/depression grew stronger in the upper quantiles of the GAD-7 and PHQ-9 distributions, well beyond scale cut-offs for probable clinical relevance. We hypothesize that negative illness perceptions of HIV/AIDS and severity of depression and anxiety symptoms may mutually reinforce each other. Illness perceptions are a promising intervention target for improving the mental health of PLWHA.

Interactive effects of cold spell and air pollution on outpatient visits for anxiety in three subtropical Chinese cities

BACKGROUND

Although low temperature and air pollution exposures have been associated with the risk of anxiety, their combined effects remain unclear.

OBJECTIVE

To investigate the independent and interactive effects of low temperature and air pollution exposures on anxiety.

METHOD

Using a case-crossover study design, the authors collected data from 101,636 outpatient visits due to anxiety in three subtropical Chinese cities during the cold season (November to April in 2013 through 2018), and then built conditional logistic regression models based on individual exposure assessments [temperature, relative humidity, particulate matter (PM_2.5, PM₁₀), sulfur dioxide (SO₂), and nitrogen dioxide (NO₂)] and twelve cold spell definitions. Additive-scale interactions were assessed using the relative excess risk due to interaction (RERI).

RESULTS

Both cold spell and air pollution were significantly associated with outpatients for anxiety. The effects of cold spell increased with its intensity, ranging from 8.98% (95% CI: 2.02%, 16.41%) to 15.24% (95% CI: 6.75%, 24.39%) in Huizhou. Additionally, each 10 μg/m³ increase of PM_2.5, PM₁₀, NO₂ and SO₂ was associated with a 1.51% (95% CI: 0.61%, 2.43%), 1.58% (95% CI: 0.89%, 2.28%), 13.95% (9.98%, 18.05%) and 11.84% (95% CI: 8.25%, 15.55%) increase in outpatient visits for anxiety. Synergistic interactions (RERI >0) of cold spell with all four air pollutants on anxiety were observed, especially for more intense cold spells. For particulate matters, these interactions were found even under mild cold spell definitions [RERI: 0.11 (95% CI: 0.02, 0.21) for PM_2.5, and 0.24 (95% CI: 0.14, 0.33) for PM₁₀]. Stratified analyses yielded a pronounced results in people aged 18-65 years.

CONCLUSIONS

These findings indicate that both cold spell and air pollution are important drivers of the occurrence of anxiety, and simultaneous exposure to these two factors might have synergistic effects on anxiety. These findings highlight the importance of controlling air pollution and improving cold-warning systems.

Influencing Factors of International Students’ Anxiety Under Online Learning During the COVID-19 Pandemic: A Cross-Sectional Study of 1,090 Chinese International Students

Objective

We conducted the following cross-sectional study to comprehensively assess the anxiety among Chinese international students who studied online during the COVID-19 pandemic and its influencing factors.

Methods

Questionnaires were distributed through “Sojump,” and a total of 1,090 valid questionnaires were collected. The questionnaire was divided into two parts: general situation and anxiety assessment of students. The former used a self-made questionnaire, and the international general GAD-7 scale was used to measure anxiety. Chi-square test was used to analyze the differences between groups, and logistic regression analysis was performed for the factors with differences.

Results

Anxiety was found in 707 (64.9%) of 1,090 international students. Chi-square test and multivariate Logistic regression analysis showed that the incidence of anxiety was higher in the group under 22 years of age than in the group over 22 years of age (68% vs. 61%, p = 0.015; OR = 1.186, 95% CI 1.045–1.347, p = 0.008); International students living in big cities had a higher incidence of anxiety than those living in rural areas (67% vs. 60%, p = 0.022; OR = 1.419, 95%CI 1.038–1.859, p = 0.011); international students who socialized 3 times or less monthly had a higher incidence of anxiety than those who socialized more than 3 times per month (68% vs. 58%, p = 0.003; OR = 1.52, 95%CI 1.160–1.992, p = 0.002); international students who expected purely online teaching had a higher incidence of anxiety than those who expected purely offline teaching or dual-track teaching (72% vs. 64%, p = 0.037; OR = 1.525, 95%CI 1.069–2.177, p = 0.02); international students with a subjective score of online learning experience of 6 or less had a higher incidence of anxiety than those with subjective scores of more than 6 (70% vs. 60%, p = 0.001, OR = 1.25, 95%CI 1.099–1.422, p = 0.001). However, gender, emotional status, BMI, major of study, vaccination status, and degree type had no significant difference in the incidence of anxiety among international students who studied online during the COVID-19 pandemic.

Conclusion

During COVID-19, international students who were younger, came from big cities, had low social frequency, expected purely online teaching, and had poor experience of online classes were risk factors for anxiety during online classes.

Anxiety Status and Associated Factors of Health Personnel Working in a Tertiary Hospital in Turkey in the COVID-19 Pandemic

Aim: This research was conducted to evaluate the anxiety status and related factors of tertiary hospital personnel working in a densely populated area of ​​Turkey during the COVID-19 pandemic. Methods: A total of 555 participants were included in this cross-sectional, prospective study. A socio-demographic data form was created and the Beck Anxiety Scale was applied to participants for evaluating anxiety status. Results: The rate of men 64.86% (n=360) and women 35.14% (n=195). The distribution of anxiety scores was in the range of 8.39±9.16. 58.2% of them (n=323) had low, 41.8% (n=232) had high anxiety scores. Factors like age, gender, marital status, working status in areas where treatment/care is provided to suspected/positive patients with COVID-19, and fear of carrying infection from work to home are found to be statistically significantly related to anxiety. Conclusion: High anxiety scores were measured in almost half of the participants. Taking measures to improve risk factors can reduce the damaging effects of the challenging working conditions due to the ongoing COVID-19 pandemic on hospital personnel. Keywords: anxiety, COVID-19, health, health personnel, pandemics

Prevalence of Moderate to Severe Anxiety Symptoms among Patients with Myocardial Infarction: a Meta-Analysis

This study attempted to synthesize the evidence on the prevalence of moderate to severe anxiety symptoms among myocardial infarction (MI) patients to offer a reliable and accurate estimate on the number of MI patients suffering from moderate to severe anxiety symptoms. Comprehensive electronic searches (PubMed, Embase and Web of Science) were performed from their inception to February 2021. Between-study heterogeneity was analyzed using the Cochran's Q test and [Formula: see text] statistic, and if it was high across the eligible studies, meta-regression and subgroup analyses were conducted to examine the source of heterogeneity. Publication bias and the robustness of the pooled results were also examined. A total of 18 eligible studies covering 8,532 MI patients were included, of which 3,443 were identified with moderate to severe anxiety symptoms. Between-study heterogeneity was high ([Formula: see text]=98.8%) with the reported prevalence ranging from 9.6% to 69.17%, and the pooled prevalence was 38.08% (95% confidence interval: 28.82-47.81%) by a random-effects model. Meta-regression analyses indicated that publication year (β = -0.014) was significant moderators contributing 16.11% to the heterogeneity. Subgroup analyses indicated that studies using the anxiety subscale of Brief Symptom Inventory to assess anxiety were homogenous ([Formula: see text]=0.0). Furthermore, the pooled prevalence of moderate to severe anxiety symptoms varied significantly by geographic region, instrument used to assess anxiety, methodological quality, sex, education level, a history of previous MI and hypercholesterolemia. Additionally, the results of Egger's linear test (t = -0.630) and Begg's rank test (z = -0.190) indicated no evidence of publication bias, and the sensitivity of the pooled results was low. Nearly two fifth of MI patients suffered from moderate to severe anxiety symptoms, which emphasizes the importance of early identification of anxiety symptoms after MI, as well as the need of implementing psychological interventions for those with elevated anxiety symptoms.

Affective Representation of Early Relationships with Parents and Current Anxiety and Depression

Research on the role of early relationships with parents on youth's anxiety and depression, especially in collectivist societies such as China, is limited. To fill this gap, we investigated the unique role of early relationship with mothers and fathers, respectively, in Chinese youth's anxiety and depression outcomes. The participants were 347 Chinese college students from 20 provinces. They first separately rated the frequency of experiencing 13 emotions (e.g., anger) from recalling early relationships with their mothers and fathers, then completed the Zung Self-Rating Anxiety Scale and the Zung Self-Rating Depression Scale. Logistic regression was performed to determine the unique contribution of early relationships with mothers and fathers, respectively, to the participants' clinical-level anxiety and depression. Based on the final model of our logistical regression, we found that an increase in negative affective representation of early relationship with the mother was associated with a higher likelihood of clinical level anxiety (OR = 3.58; 95% CI = 1.32-9.70), while an increase in positive affective representation of early relationship with the mother was associated with a lower likelihood of clinical-level depression (OR = 0.47; 95% CI = 0.25-0.87). Furthermore, an increase in negative affective representation of early relationship with the father was associated with a higher likelihood of clinical-level anxiety (OR = 3.36; 95% CI = 1.37-8.26) and depression (OR = 3.68; 95% CI = 1.59-8.52), above and beyond their affective representation of early relationship with the mother.

Knowledge, Attitudes, and Practices Toward Coronavirus and Associated Anxiety Symptoms Among University Students: A Cross-Sectional Study During the Early Stages of the COVID-19 Pandemic in Bangladesh

BACKGROUND

University students' knowledge, attitude, and practice (KAP) toward COVID-19 are vital to prevent the spread of the virus, especially in the context of developing countries. Consequently, the present study aimed to determine the KAP levels of university students and associated anxiety during the earlier stage of the pandemic in Bangladesh.

METHODS

A cross-sectional, online study with 544 university students was conducted during April 17-May 1, 2020. The questionnaire incorporated several KAP-related test items aligned with the World Health Organization (WHO) guidelines. Anxiety was measured with the 2-item Generalized Anxiety Disorder scale (GAD-2). Multivariable logistic regression analysis was performed to determine the association between KAP levels and anxiety adjusting for sociodemographic variables. Subgroup analyses included rerunning models stratified by gender and quarantine status.

RESULTS

Approximately 50% of students showed high levels of knowledge about COVID-19 guidelines, 59% reported behavioral practices that aligned with COVID-19 guidelines, and 39% had negative attitudes toward COVID-19 guidelines. Attitudes differed by anxiety (χ² = 23.55, p < 0.001); specifically, negative attitudes were associated with higher anxiety (OR: 2.40, 95% CI = 1.66-3.46, p < 0.001). Associations were significant for male (OR = 2.36; 95% CI = 1.45-3.84, p < 0.001) and female (OR = 2.45; 95% CI = 1.3-4.34; p < 0.001) students. Stratified analyses found non-quarantined students with negative attitudes had three times the chance of experiencing anxiety (OR = 3.14, 95% CI: 1.98-4.98, p < 0.001). Non-quarantined students with low levels of knowledge had half the chance of developing anxiety (OR = 0.49, 95% CI: 0.31-0.78, p < 0.01).

CONCLUSION

Based on these findings, it is recommended that university authorities continue to prioritize proactive and effective measures to develop higher levels of knowledge, more positive attitudes and better behavioral practices regarding COVID-19 for the mental health of their students.

Anxiety and Food Addiction in Men and Women: Results From the Longitudinal LIFE-Adult-Study

BACKGROUND

Anxiety is a widespread phenomenon, and it is connected to disordered eating and obesity. We want to analyze the connection between anxiety and food addiction (FA) over two points in time to better understand the directionality of the association. Since there are gender differences with regard to anxiety and eating, we are also interested in differences between men and women.

METHODS

We used data from the population-based LIFE-Adult-Study (N = 1,474) at time 1 (baseline) and time 2 (first follow-up) to analyze the connections between anxiety (GAD-7) and FA (YFAS) using a multiple group latent cross-lagged panel model with female and male participants as groups. We controlled for age, marital status, socioeconomic status and social support.

RESULTS

Anxiety (women: β = 0.50, p ≤ 0.001; men: β = 0.59, p ≤ 0.001) as well as FA (women: β = 0.37, p ≤ 0.001; men: β = 0.58, p ≤ 0.001) exhibited stability over time for both genders. We found a significant association between anxiety at time 1 and FA at time 2 for women (β = 0.25, p ≤ 0.001) but not for men (β = 0.04, p = 0.10), and significant associations between FA at time 1 and anxiety at time 2 for women (β = 0.23, p ≤ 0.001) as well as men (β = 0.21, p ≤ 0.001).

CONCLUSION

Food addiction longitudinally affects anxiety, independent of gender and other sociodemographic variables. In addition, anxiety affects subsequent FA as well, but only in women. Interventions that address FA could reduce anxiety in men and women, while interventions that mitigate anxiety could help prevent FA in women.

Association Between Early Parental Death and Loneliness in Adulthood: A Community-Based Study in Southwest China

Loneliness is a growing public health problem that threatens physical and mental health to a large extent. Compelling evidence has shown that premature parental death is strongly associated with many mental health disorders in adulthood, but whether it increases the risk of loneliness remains unclear. In this large community-based study, we included 32,682 adult participants (20-93 years old) from Southwest China and used the three-item short version of University of California, Los Angeles, Loneliness Scale to identify participants with loneliness. A total of 1,975 participants reported loneliness, which resulted in a loneliness prevalence of 6.0% in Southwest China. Logistic regression was used to evaluate the association between early parental death and loneliness after adjusting for age, gender, education level, marital status, smoking and drinking status, living status, and chronic diseases. We found that early parental death was significantly associated with loneliness [odds ratio (OR) = 1.21, 95% confidence interval (CI), 1.03-1.42]. A Sensitivity analysis excluding those with mental health disorders (796 participants) yielded similar results (OR = 1.26, 95% CI = 1.06-1.49). We also found that being younger, single, divorced, or widowed, and more educated; living alone; and having chronic disorders were associated with loneliness. We conclude that childhood parental death is associated with loneliness in adulthood, suggesting the need for early intervention in affected children to prevent long-term adverse neuropsychiatric effects.

Evolution in French University Students' Mental Health One Month After the First COVID-19 Related Quarantine: Results From the COSAMe Survey

INTRODUCTION

The COVID-19 related quarantine had negative psychological effects among University students. Evidence from previous epidemics suggests that negative psychological effects of quarantine measures can last or even worsen after the quarantine lift. The objective of this study was to assess the evolution of students' mental health and to identify factors associated with mental health outcomes 1 month after the lift of the lockdown.

MATERIALS AND METHODS

This repeated cross-sectional study collected data during the first quarantine in France (T1, N = 68,891) and 1 month after its lift (T2, N = 22,540), through an online questionnaire sent to all French University students. Using cross-sectional data, we estimated prevalence rates of suicidal thoughts, severe anxiety (State-Trait Anxiety Inventory, State subscale), depression (Beck Depression Inventory), and stress (Perceived Stress Scale) at T1 and T2. Using longitudinal data (N = 6,346), we identified risk factors of poor mental health outcomes among sociodemographic characteristics, precariousness indicators, health-related data, information on the social environment, and media consumption, adjusting for baseline mental health status.

RESULTS

We found lower prevalence rates of severe stress (21.7%), anxiety (22.1%), and depression (13·9%) one month after the quarantine compared to the quarantine period (24.8%, 27.5%, and 16.1%, respectively). The prevalence rate of suicidal thoughts increased from 11.4 to 13.2%. Regardless of the existence of symptoms during quarantine, four factors were systematically associated with poor mental health outcomes 1 month after the quarantine was lifted: female gender, a low feeling of integration before the quarantine period, a low quality of social ties during the quarantine, and a history of psychiatric follow-up.

CONCLUSIONS

The prevalence rates of severe stress, anxiety, and depression, although being lower than during the first lockdown, remained high after its lift. The prevalence rate of suicidal ideation increased. This stresses the need to consider the enduring psychological impact of the pandemic on students as a critical public health issue.

Relative Safety and Efficacy of Two Doses of Tandospirone Citrate for Generalized Anxiety Disorder: A Multicenter Randomized Controlled Trial

PURPOSE

To determine the relative safety and efficacy of different doses of tandospirone in treating generalized anxiety disorder (GAD).

PATIENTS AND METHODS

This parallel randomized controlled trial enrolled patients with GAD from eight centers in China. The patients were randomly assigned to 60 mg/day or 30 mg/day tandospirone groups. The primary endpoint was the overall response rate after receiving 6-week treatment. The secondary endpoints included significant response rate, clinical recovery rate, change in the Hamilton Anxiety Scale (HAMA) total score, HAMA subscale score, Hamilton Depression Scale-17 (HAMD-17), Clinical Global Impression-Severity Scale (CGI-S) score, and Impression-Improvement scale (CGI-I) score.

RESULTS

No significant difference was found in the overall response rate between the two groups (65.7% vs 58.4%, p = 0.213). A higher significant response rate and change in the HAMA total score were found in the 60 mg/day group. The reduction in the CGI-S score and percentage of patients with a CGI-I score of ≤2 were higher in 60 mg/day group. The reduction in HAMA somatic anxiety factor, cardiovascular symptom factor, gastrointestinal symptom factor, and HAMD-17 score were more significant in the 60 mg/day group. The incidence of total adverse events was higher in the 60 mg/day group than in the 30 mg/day group. No significant difference was found in the proportion of withdrawal due to adverse events.

CONCLUSION

Both 60 mg/day and 30 mg/day tandospirone show good efficacy in treating patients with GAD. High doses of tandospirone may have advantages in relieving the somatic symptoms but also present disadvantages due to their high level.

TRIAL REGISTRATION

The trial registration no. was NCT01614041.

Psychological distress among cancer survivors during implementation of a nationwide Movement Control Order over the COVID-19 pandemic

OBJECTIVES

This study aimed to investigate the psychological distress and its associated factors among cancer survivors in Malaysia during the COVID-19 pandemic.

METHODS

An anonymous Internet-based study was conducted between 23 April and 26 June 2020. During the study period, the country underwent phase 3 and phase 4 of the Movement Control Order (MCO), Conditional Movement Control Order (CMCO), and Recovery Movement Control Order (RMCO). Psychological distress was measured using the Hospital Anxiety and Depression Scale (HADS), which is a 14-item self-assessment scale for measuring distress (total HADS score; HADS-T) with two subscales, namely, anxiety (HADS-A) and depression (HADS-D). Perceived threat of infection was measured based on the health belief model.

RESULTS

From a total of 631 responses received, the proportion of participants with anxiety and depression symptoms (above threshold score of 8 on HADS-A and HADS-D) was 29.0 and 20.9%, respectively. Psychological distress (HADS-T > 16) was reported in 22.3% of the respondents. A total of 16.5% had combined anxiety and depression symptoms. The highest HADS-A (6.10; 95% CI 5.64-6.56), HADS-D (5.61; 95% CI 5.14-6.08), and HADS-T (11.71; 95% CI 10.84-12.58) scores were reported among respondents during phase 4 of the MCO. Partial least square-based structural equation modelling (PLS-SEM) revealed that self-perceived health status, perceived susceptibility, and severity of COVID-19 have the greatest effect, leading to higher HADS-A, HADS-D, and HADS-T scores.

CONCLUSION

Heightened psychological distress was evident in cancer survivors particularly during the enforcement of the MCO over COVID-19. Providing support to address cancer survivors' psychological and emotional needs during the COVID-19 pandemic is essential.

Predictors of Persistence of Anxiety, Hyperarousal Stress, and Resilience During the COVID-19 Epidemic: A National Study in Iran

Background: The coronavirus pandemic can cause unprecedented global anxiety, and, in contrast, resilience can help the mental health of people in stressful situations. This study aimed to assess anxiety, hyperarousal stress, the resilience of the Iranian population, and their related factors during the coronavirus disease 2019 (COVID-19) epidemic. Methods: A cross-sectional study was conducted in 31 provinces in Iran between March 18 and 25, 2020. A four-part questionnaire, including the demographic information, the State-Trait Anxiety Inventory (STAI-y1-a 20-item standard questionnaire for obvious anxiety), the Connor-Davidson Resilience Scale (CD-RISC-a 25 item standard questionnaire), and the stress hyperarousal subscale from the Impact of Event Scale-Revised (IES-R), was used to collect data. The ordinal multivariable generalized estimating equation (GEE) model was used to identify correlates of the psychological factors mentioned above. The Fisher exact test was used to investigate the relationship between anxiety, stress, resilience, and the COVID-19 outbreak. All analyses were conducted with SPSS 26 and GIS 10.71. Results: The findings show that most people had moderate-to-severe anxiety (80.17%) and a high level of resilience (96.4%) during the COVID-19 epidemic. The majority of participants had a moderate level of stress (58.9%). The lowest and highest prevalences of psychiatric disorders were in Sistan and Baluchestan (3.14 cases per 100,000 people) and Semnan (75.9 cases per 100,000 people) provinces, respectively. Men and unmarried people were the only variables significantly associated with anxiety and resilience. Age, gender, and education were significantly associated with hyperarousal stress. Conclusion: The high and moderate levels of anxiety and stress in Iranians can have negative effects on the well-being and performance of the people and can lead to serious problems. Also, high resilience during negative life events (such as the COVID-19 pandemic) is associated with the well-being in the lives of people. The results of this study can be used in interventions and other psychological studies.

Relationship between the Severity of Anxiety Symptoms, Aggression and Alcohol Consumption during the COVID-19 Pandemic Period

Background and objectives: There have been many reports of mental health in the pandemic period. The research conducted so far has indicated an increase in the severity of anxiety and aggression and an escalation of alcohol consumption during the COVID-19 pandemic. The aim of this study was to determine the relationship between the severity of anxiety, the amount of alcohol consumed and the severity of aggression. Materials and Methods: A total of 538 Polish residents—413 women (76.77%) and 125 men (23.23%)—participated in the study via an online survey. It included socio-demographic parameters and psychological scales: AUDIT—to determine the model of alcohol consumption, GAD-7—to measure the severity of anxiety and the Buss–Perry Aggression Questionnaire. Results: There was a correlation between the severity of anxiety and generalized aggression, and its two components—anger and hostility—in the entire study group. Moreover, relations were found between the intensity of alcohol consumption and generalized aggression and its components—anger and verbal and physical aggression. Those relationships turned out to be gender specific. The increased anxiety intensity affected the pattern of alcohol consumption and the severity of aggression. Conclusions: Psychotherapeutic and psychoeducational interactions and some elements of psychiatric treatment should aim at reducing the severity of anxiety in society, and thus minimizing the health and social consequences—aggressive behaviour and excessive alcohol consumption.

The influence of illness perception, anxiety and depression disorders on students mental health during COVID-19 outbreak in Pakistan: a Web-based cross-sectional survey

Purpose

Since the emergence of a coronavirus disease (2019-nCoV) in December 2019, the whole world is in a state of chaos. Isolation strategy with quarantine is a useful model in controlling transmission and rapid spread. As a result, people remained at home and disrupted their outside daily activities. It led to the closure of educational institutes, which is a source of many students to cope with numerous personal and familial issues. This study aims to focus on exploring the relationships and potential mediational pathways between mental health problems, illness perception, anxiety and depression disorders.

Design/methodology/approach

The study incorporated snowball sampling techniques through a cross-sectional, Web-based survey and recruited 500 students from different universities of twin cities, Rawalpindi and Islamabad from March 23 to April 15, 2020, during the coronavirus outbreak lockdown. The study used four instruments, Beck Depression Scale, Beck Anxiety Inventory, Revised Illness Perception Questionnaire and The Warwick-Edinburgh Mental Well-being Scale for assessing depression, anxiety, illness perception and mental health disorders.

Findings

The findings indicated normal (43.2%), mild (20.5%), moderate (13.6%) and severe (22.7%) levels of anxiety prevalence in students. Results specified a normal (65.9%), mild (9.10%), moderate (9.12%) and severe (15.90%) depression prevalence and findings stipulated that anxiety disorder prevalence was higher than depression disorder. The correlational results specified a negative and significant relationship between mental health, illness perception, anxiety and depression symptoms. The multiple regression analysis stated that anxiety and depression disorders mediated the relationship between mental health and present illness perception. The perception of illness exhibited a relation to depression and anxiety disorders.

Originality/value

The study proposed a model to address mental health problems during the lockdown. The (2019-nCoV) illness perception developed mental disorders, including anxiety and depression, which has declined individuals’ mental health. There is an urgent need for ongoing clinical examination and management to address psychological disorders and findings suggest assessing mental health to combatting the pandemic worldwide. Findings recommend developing strategies to promote mental health-care facilities during COVID-19 wide-ranging disasters. These results highlight the impending importance of devising strategies to treat mental health problems.

Generalized Anxiety Disorder During the COVID-19 Outbreak in Iran: The Role of Social Dysfunction

ABSTRACT

The COVID-19 epidemic has both physical and psychosocial consequences for the general population. The present study aimed to investigate the relationship between the prevalence of generalized anxiety disorder (GAD) and social dysfunction during the COVID-19 epidemic in Iran. This cross-sectional web-based study was conducted on 1000 Rafsanjani citizens in southeastern Iran. Data were collected by using the Generalized Anxiety Disorder-7 and the General Health Questionnaire from March 15 to March 30, 2020. The prevalence of GAD was 27.8%. The mean score of social functioning was 9.71 ± 2.66, and all participants had social dysfunction. Multivariate logistic regression test showed a significant correlation between anxiety and social functioning (confidence interval [CI], 1.16-1.30; p < 0.001), sex (CI, 1.49-3.04; p < 0.001), and concern about COVID-19 (CI, 1.38-2.73; p < 0.001). The COVID-19 epidemic had negative psychosocial consequences in the general population in Iran.

Anxiety and associated factors among Ethiopian health professionals at early stage of COVID-19 pandemic in Ethiopia

Introduction

In late 2019, a new coronavirus disease known as COVID-19 (novel coronavirus disease 2019) was identified. As there is no any drug to treat this pandemic, the healthcare professionals are disproportionately at higher risk. The mental health outcome is expected to be high. Anxiety is expected to have a significant impact on health professionals, especially among those who work without adequate resources for self-protection.

Objectives

The objectives of this research was to assess self-reported anxiety symptoms and associated factors among Ethiopian healthcare professionals in the early stages of the pandemic.

Methods

We have conducted an online cross-sectional study to collect information from healthcare professionals in Ethiopia during the early stage of the outbreak from April 7, 2020 to May 19, 2020. GAD-7 was used for measurement of anxiety. We have used a cut of point of 10 and above to report anxiety symptoms. We have used Google Forms for online data collection and SPSS-22 for analysis. To determine associated factors for anxiety, a binary logistic regression model was used. Variables with p-value < 0.2 during the bivariable binary logistic regression were exported for further analysis in the multivariable binary logistic regression. Finally, variables with p-value <0.05 were considered as significantly associated with the outcomes.

Results

Three hundred and eighty-eight healthcare professionals filled the online questionnaire; Majority (71.1%) were males. Significant number of respondents (78.9%) reported lack of adequate personal protective equipment (PPE) at the work place. The prevalence of anxiety was 26.8%.

Being female (AOR: 1.88; 95% C.I:1.11, 3.19), visiting/treating 30–150 patients per day (AOR: 3.44; 95% C.I:1.51, 7.84), those employed at private healthcare institutions (AOR: 2.40; 95% C.I:1.17, 4.90), who do not believe that COVID-19 is preventable (AOR: 2.04; 95% C.I:1.04, 4.03) and those who reported lack of PPE (AOR: 1.98; 95% C.I:1.04, 3.79) were more likely to be anxious.

Conclusions

The anxiety prevalence among healthcare professionals in Ethiopia during early stage of COVID-19 pandemic was high. This study shows that lack of preventive equipment, being female, contact with many patients, low self-efficacy and working in private health facilities were risk factors for anxiety. Anxiety prevention among health professionals during COVID-19 pandemic requires a holistic approach including provision of sufficient PPE, improving self-efficacy and addressing problems both at public and private institutions and focusing more on female health professionals.

Depression, anxiety, stress and their associated factors among Ethiopian University students during an early stage of COVID-19 pandemic: An online-based cross-sectional survey

BACKGROUND

The occurrence of the Coronavirus Disease 2019 (COVID-19) affects the mental health situation of almost everyone, including University students who spent most of their time at home due to the closure of the Universities. Therefore, this study aimed at assessing depression, anxiety, stress and identifying their associated factors among university students in Ethiopia during the early stage of the COVID-19 pandemic.

METHODS

We invited students to complete an online survey using Google forms comprising consent, socio-demographic characteristics, and the standard validated depression, anxiety, and stress scale (DASS-21) questionnaire. After completion of the survey from June 30 to July 30, 2020, we exported the data into SPSS 22. Both descriptive and analytical statistics were computed. Associated factors were identified using binary logistic regression and variables with a p-value <0.05 were declared as statistically significant factors with the outcome variables.

RESULTS

A total of 423 students completed the online survey. The prevalence of depression, anxiety, and stress in this study was 46.3%, 52%, and 28.6%, respectively. In the multivariable model, female sex, poor self-efficacy to prevent COVID-19, those who do not read any material about COVID-19 prevention, lack of access to reading materials about their profession, and lack of access to uninterrupted internet access were significantly associated with depression. Female sex, lower ages, students with non-health-related departments, those who do not think that COVID-19 is preventable, and those who do not read any materials about COVID-19 prevention were significantly associated with anxiety. Whereas, being female, students attending 1st and 2nd years, those who do not think that COVID-19 is preventable, presence of confirmed COVID-19 patient at the town they are living in, and lack of access to reading materials about their profession were significantly associated with stress.

CONCLUSIONS

Depression, anxiety, and stress level among University students calls for addressing these problems by controlling the modifiable factors identified and promoting psychological wellbeing of students.

Prevalence and changes in boredom, anxiety and well-being among Ghanaians during the COVID-19 pandemic: a population-based study

BACKGROUND

The outbreak of the COVID-19 pandemic has been associated with several adverse health outcomes. However, few studies in sub-Saharan Africa have examined its deleterious consequences on mental health. Therefore, we investigated the prevalence and changes in boredom, anxiety and psychological well-being before and during the COVID-19 pandemic in Ghana.

METHODS

Data for this study were drawn from an online survey of 811 participants that collected retrospective information on mental health measures including symptoms of generalized anxiety disorder, boredom, and well-being. Additional data were collected on COVID-19 related measures, biosocial (e.g. age and sex) and sociocultural factors (e.g., education, occupation, marital status). Following descriptive and psychometric evaluation of measures used, multiple linear regression was used to assess the relationships between predictor variables and boredom, anxiety and psychological well-being scores during the pandemic. Second, we assessed the effect of anxiety on psychological well-being. Next, we assessed predictors of the changes in boredom, anxiety, and well-being.

RESULTS

Before the COVID-19 pandemic, 63.5% reported better well-being, 11.6% symptoms of anxiety, and 29.6% symptoms of boredom. Comparing experiences before and during the pandemic, there was an increase in boredom and anxiety symptomatology, and a decrease in well-being mean scores. The adjusted model shows participants with existing medical conditions had higher scores on boredom (ß = 1.76, p < .001) and anxiety (ß = 1.83, p < .01). In a separate model, anxiety scores before the pandemic (ß = -0.25, p < .01) and having prior medical conditions (ß = -1.53, p < .001) were associated with decreased psychological well-being scores during the pandemic. In the change model, having a prior medical condition was associated with an increasing change in boredom, anxiety, and well-being. Older age was associated with decreasing changes in boredom and well-being scores.

CONCLUSIONS

This study is the first in Ghana to provide evidence of the changes in boredom, anxiety and psychological well-being during the COVID-19 pandemic. The findings underscore the need for the inclusion of mental health interventions as part of the current pandemic control protocol and public health preparedness towards infectious disease outbreaks.

Involvement of Chaperone Sigma1R in the Anxiolytic Effect of Fabomotizole

Sigma-1 receptor (chaperone Sigma1R) is an intracellular protein with chaperone functions, which is expressed in various organs, including the brain. Sigma1R participates in the regulation of physiological mechanisms of anxiety (Su, T. P. et al., 2016) and reactions to emotional stress (Hayashi, T., 2015). In 2006, fabomotizole (ethoxy-2-[2-(morpholino)-ethylthio]benzimidazole dihydrochloride) was registered in Russia as an anxiolytic (Seredenin S. and Voronin M., 2009). The molecular targets of fabomotizole are Sigma1R, NRH: quinone reductase 2 (NQO2), and monoamine oxidase A (MAO-A) (Seredenin S. and Voronin M., 2009). The current study aimed to clarify the dependence of fabomotizole anxiolytic action on its interaction with Sigma1R and perform a docking analysis of fabomotizole interaction with Sigma1R. An elevated plus maze (EPM) test revealed that the anxiolytic-like effect of fabomotizole (2.5 mg/kg i.p.) administered to male BALB/c mice 30 min prior EPM exposition was blocked by Sigma1R antagonists BD-1047 (1.0 mg/kg i.p.) and NE-100 (1.0 mg/kg i.p.) pretreatment. Results of initial in silico study showed that fabomotizole locates in the active center of Sigma1R, reproducing the interactions with the site's amino acids common for established Sigma1R ligands, with the ΔGbind value closer to that of agonist (+)-pentazocine in the 6DK1 binding site.

The Prevalence of Psychological Status During the COVID-19 Epidemic in China: A Systemic Review and Meta-Analysis

The COVID-19 is creating panic among people around the world and is causing a huge public mental health crisis. Large numbers of observational studies focused on the prevalence of psychological problems during the COVID-19 pandemic were published. It is essential to conduct a meta-analysis of the prevalence of different psychological statuses to insight the psychological reactions of general population during the COVID-19 epidemic in China. Sixty six observational studies about the psychological statuses of people during the COVID-19 were included, searching up to 1 December 2020. Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) was used to evaluate the quality of the included studies. OpenMeta[Analyst] was used for the data analysis. High prevalence of acute stress and fear symptoms were observed in the early period of the epidemic. Additionally, anxiety and depression symptoms continued at a high prevalence rate during the epidemic. It should alert the lasting mental health problems and the risk of post-traumatic stress disorder and other mental disorders. Systematic Review Registration: PROSPERO CRD 42020171485.

Prevalence and factors associated with depressive and anxiety symptoms in a Chinese population with and without cardiovascular diseases

BACKGROUND

Few data have reported the prevalence of depressive and anxiety symptoms in patients with cardiovascular disease (CVD) in China. Our study aimed to estimate the prevalence and related risk factors of these mental health symptoms.

METHODS

A total of 47841 participants from seven regions of China were enrolled by a two-stage, stratified, community-based, clustering sampling strategy between 2014 and 2016. Data of sociodemographic status and medical history were collected through a standard questionnaire. The Center for Epidemiologic Studies Depression Scale and Zung's self-rating anxiety scale were used to screen depressive and anxiety symptoms.

RESULTS

Among 47588 individuals who completed the self-report questionnaires, the weighted prevalence of depressive symptom was 2.9% and that of anxiety symptom was 1.5%. In females with heart failure (HF) and stroke, prevalence of either depressive and anxiety symptoms were 15.1% and 13.8%, respectively; while 9.4% and 8.4% for the male counterparts. Among patients with ≥ any 3 specific CVDs, the prevalence of having either depressive or anxiety symptoms were 13.1% and 6.8% for females and males, respectively. Younger age, female, unmarried, lower income, and disease history of atrial fibrillation, HF and stroke tend to link with higher risks of mental health symptoms.

LIMITATIONS

Cross-sectional study.

CONCLUSION

A high proportion of patients with CVD had depressive and anxiety symptoms. Screening for mental health symptoms is more important in higher-risk populations who are at younger age, being female, unmarried, with low income, and with diagnoses of atrial fibrillation, HF, and stroke.

Adverse Psychological Reactions and Psychological Aids for Medical Staff During the COVID-19 Outbreak in China

Background: The outbreak of the novel coronavirus disease COVID-19 caused panic and psychological stress throughout the World. We investigated the extent of adverse psychological reactions in two medical staff groups in China, and explored the importance of online psychological assistance for them. Methods: A cross-sectional online survey including Hospital Anxiety and Depression Scale (HADS) and Insomnia Severity Index (ISI) was utilized to assess anxiety, depression, and insomnia. Propensity score matching (PSM) was applied to match sex and age between the two groups. Differences in the prevalence of adverse psychological reactions between the two groups were compared by a Chi-square test. A multivariate logistic regression analysis was utilized to search for associated adverse psychological reaction factors of two groups. Results: A total of 2,920 medical staff took part in the survey, including 470 frontline and 2,450 non-frontline medical staff. The risk of the frontline group experiencing anxiety, depression, insomnia-early, insomnia-middle, and insomnia-late were 1.16, 1.28, 1.26, 1.22, 1.28 times those of the non-frontline group after PSM. For frontline medical staff, the spinsterhood state (OR = 1.23, 95% CI: 1.00-1.51; P = 0.05) was a risk factor for anxiety. Bachelor or college degree (OR = 2.23, 95% CI: 1.24-4.02, P = 0.01) and a contact history with COVID-19 patients (OR = 1.62, 95% CI: 1.10-2.40; P = 0.02) were risk factors for insomnia. For non-frontline medical staff, being a woman (OR = 1.49, 95% CI: 1.08-2.06, P = 0.01) was a risk factor for anxiety, whilst being in a middle age group was a protective factor for anxiety (OR = 0.70, 95% CI: 0.50-0.99, P = 0.04) and depression (OR = 0.65, 95% CI: 0.45-0.93, P = 0.02). Being a woman (OR = 1.47, 95% CI: 1.14-1.89, P = 0.003) and working in a COVID-19 unit (OR = 1.31, 95% CI: 1.11-1.54, P = 0.001) were risk factors for insomnia, whilst the spinsterhood state (OR = 0.80, 95% CI: 0.67-0.95; P = 0.01) was a protective factor for insomnia. Online forms of psychological aid were all popular with medical staff. Conclusions: The prevalence of anxiety, depression, and insomnia in frontline medical staff was significantly higher than in the non-frontline group. Appropriate intervention methods should be adopted according to the different influencing factors of the two groups. Online psychological aid was the preferred mechanism for relieving psychological problems.

Depression and anxiety in the Malaysian urban population and their association with demographic characteristics, quality of life, and the emergence of the COVID-19 pandemic

The prevalence of depression and anxiety has been shown to be higher in the urban population compared with the rural population. The present study investigated the prevalence of depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms and their associated factors in a random sample drawn from several urban communities in Malaysia. This study also determined the association between the emergence of the COVID-19 pandemic and depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms. We recruited 326 participants, who were administered a sociodemographic characteristics questionnaire; the 21-item Depression, Anxiety, and Stress Scale (DASS-21) to assess the presence or absence of depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms; and the World Health Organization Quality of Life-BREF (WHOQoL-BREF) to assess their QoL. The following prevalence values were obtained among the participants: depression symptoms, 23.9%; anxiety symptoms, 41.7%; and depression with comorbid anxiety symptoms, 19.9%. Those assessed after the declaration of COVID-19 as a global pandemic showed increased odds of depressive symptoms (adjusted OR = 2.99, 95% CI = 1.41–6.35, p = 0.006) and depressive with comorbid anxiety symptoms (adjusted OR = 3.19, 95% CI = 1.37–7.45, p = 0.005), while the presence of comorbid stress increased the odds of depressive symptoms (adjusted OR = 16.00, 95% CI = 7.84–32.63, p < 0.001), anxiety symptoms (adjusted OR = 19.72, 95% CI = 9.75–39.89, p < 0.001), and depressive with comorbid anxiety symptoms (adjusted OR = 40.44, 95% CI = 15.90–102.87, p < 0.001). Higher psychological QoL reduced the odds of depressive symptoms (adjusted OR = 0.83, 95% CI = 0.69–0.99, p = 0.032) and depressive with comorbid anxiety symptoms (adjusted OR = 0.82, 95% CI = 0.68–0.98, p = 0.041), whereas higher physical health QoL (adjusted OR = 0.85, 95% CI = 0.75–0.97, p = 0.021) and social relationship QoL (adjusted OR = 0.70, 95% CI = 0.55–0.90, p = 0.009) reduced the odds of anxiety symptoms. Based on our findings, we recommended several measures to curb psychological complications among the urban population, particularly as the battle to contain COVID-19 is ongoing.

Prevalence of psychological disorders in the COVID-19 epidemic in China: A real world cross-sectional study

OBJECTIVE

This study aimed to explore the prevalence of psychological disorders and associated factors at different stages of the COVID-19 epidemic in China.

METHODS

The mental health status of respondents was assessed via the Patient Health Questionnaire-9 (PHQ-9), Insomnia Severity Index (ISI) and the Generalized Anxiety Disorder 7 (GAD-7) scale.

RESULTS

5657 individuals participated in this study. History of chronic disease was a common risk factor for severe present depression (OR 2.2, 95% confidence interval [CI], 1.82-2.66, p < 0.001), anxiety (OR 2.41, 95% CI, 1.97-2.95, p < 0.001), and insomnia (OR 2.33, 95% CI, 1.83-2.95, p < 0.001) in the survey population. Female respondents had a higher risk of depression (OR 1.61, 95% CI, 1.39-1.87, p < 0.001) and anxiety (OR 1.35, 95% CI, 1.15-1.57, p < 0.001) than males. Among the medical workers, confirmed or suspected positive COVID-19 infection as associated with higher scores for depression (confirmed, OR 1.87; suspected, OR 4.13), anxiety (confirmed, OR 3.05; suspected, OR 3.07), and insomnia (confirmed, OR 3.46; suspected, OR 4.71).

LIMITATION

The cross-sectional design of present study presents inference about causality. The present psychological assessment was based on an online survey and on self-report tools, albeit using established instruments. We cannot estimate the participation rate, since we cannot know how many potential subjects received and opened the link for the survey.

CONCLUSIONS

Females, non-medical workers and those with a history of chronic diseases have had higher risks for depression, insomnia, and anxiety. Positive COVID-19 infection status was associated with higher risk of depression, insomnia, and anxiety in medical workers.

Relations between Child and Parent Fears and Changes in Family Functioning Related to COVID-19

In adults, higher anxiety level related to COVID-19 has been associated with having a pre-existing medical or mental health condition and poor sleep quality. However, no study yet has looked at these links in children. The present study's main aim was to assess family changes associated with child and parent fears and concerns about COVID-19. We conducted a cross-sectional study among 144 families with children aged 9-12 years during the COVID-19 lockdown period. Families came from Quebec, Canada, and the survey was done in the early stages of the lockdown (April-May 2020). A phone-based survey assessed parent and child COVID-19-related fears and concerns, family-related changes and health issues. Results showed the more fears parents have about COVID-19, the more fears their child also has. Moreover, changes in family sleep habits were associated with parental and child fears and concerns about COVID-19. Reduced access to health services was associated with parental concerns about COVID-19. If another lockdown was to be put in place in the future, it would be important to inform families on the importance of sleep schedules and to maintain or increase health appointments when possible.

CREB1 and BDNF gene polymorphisms are associated with early treatment response to escitalopram in panic disorder

OBJECTIVES

Increasing evidence shows that the alternations under escitalopram treatment for Panic disorder (PD) patients are related to the cAMP response element-binding protein (CREB) and brain-derived neurotrophic factor (BDNF). We aimed to explore the single nucleotide polymorphisms (SNPs) of genes BDNF and CREB1 in the treatment response to escitalopram on PD.

METHODS

There were 80 PD patients with DSM-5 diagnosis and 78 healthy controls. All PD patients have received escitalopram treatment for consecutive 8 weeks. The Chinese version of Panic Disorder Severity Scale (PDSS-CV) and the Hamilton Anxiety Scale (HAMA-14) were used to evaluate the severity of panic and anxious symptoms for PD patients at baseline, week-2, week-4, and week-8, respectively. Four SNPs (rs11904814, rs6740584, rs2253206, and rs2551941) in CREB1 gene and rs6265 in BDNF gene were genotyped using matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS). Quantitative and binary genetic associations between SNPs and escitalopram treatment response were performed.

RESULTS

The comparisons of three genotypes in CREB1 SNPs rs11904814 and rs2551941 among the PDSS-CV responders showed significant differences at the end of week-2 (both p<0.05). The results remained significant after Bonferroni corrections. For candidate genes in our present study, the gene CREB1 SNP rs11904814 (p=0.007) was significantly associated with changes of PDSS-CV scores under escitalopram treatment for 12 weeks in PD patients. And the result was still significant after adjusting age and gender.

CONCLUSIONS

The findings provide preliminary evidence supporting the potential role of BDNF and CREB1 on a rapid response after escitalopram intervention in PD patients.

An analysis of mother stress before and during COVID-19 pandemic: The case of China

In this study, the authors aimed to examine relations between mothers' stress (PSI-SF) and their children during the COVID-19 pandemic confinement in mainland China (N  = 274; mean age = 32.95, SD = 5.59). Our analyses revealed mothers identified more stress problems during the confinement than before including Difficult Child, Parental Distress, and Parent-Child Dysfunctional Interaction, which predicted requests for clinical or parents support services. Mothers living in rural areas reported less stress. Single mothers and those in small households displayed a higher level of stress. Our research results may assist policymakers, professionals, and researchers to design support needed to promote families' psychological well-being.

Dopaminergic System Alteration in Anxiety and Compulsive Disorders: A Systematic Review of Neuroimaging Studies

Objective: The dopaminergic system is involved in many psychiatric disorders as a GABAergic, serotonergic, and glutamatergic system. A systematic review and meta-analysis was performed to elucidate the alteration of the dopaminergic system in anxiety and compulsive disorders.

Methods: The databases of Pubmed, Embase, and ScienceDirect were searched and articles reporting the involvement of the dopaminergic system in patients with anxiety disorder and obsessive compulsive disorder (OCD) were recognized. The key research data were extracted from the included articles and standardized mean differences were calculated using meta-analyses if there were more than two studies with obtainable data. Sensitivity analyses were further performed to detect the stability of results, and the qualities of all the included studies were assessed using the Newcastle Ottawa scale.

Results: Finally, we identified 8 and 11 studies associated with anxiety disorder and OCD for further analysis, respectively. Most consistently, the striatal dopamine D₂ receptor (D₂R) of OCD patients had decreased while no significant correlation was found between striatal D2R and disease severity. The striatal dopamine transporter (DAT) had not been significantly altered in both the anxiety disorder and OCD patients. The heterogeneity values from the meta-analyses were extremely high while those results remained stable after sensitivity analyses. Inconsistent data were found in the striatal D₂R of patients with anxiety disorder. Limited data had suggested that dopamine synthesis increased in most regions of the cerebral cortex and cerebellum in OCD patients.

Conclusions: The most convincing finding was that the D₂ receptor decreased in patients with obsessive compulsive disorder. The dopamine transporter may have no relationship with anxiety and compulsive disorder.

The association between anxiety and esophageal cancer: A nationwide population-based study

OBJECTIVE

Research on generalized anxiety disorder (GAD) and its association with esophageal cancer (EC) is sparse. The study aimed to explore the association between GAD and EC.

METHODS

A multicenter, population-based study in high-risk regions for EC (ECHRRs) was conducted from 2017 to 2019. All participants received free endoscopy screening. If the esophageal endoscopy results were suspicious, the pathological biopsy was performed to confirm normal, esophagitis, low-grade intraepithelial neoplasia (LGIN), high-grade intraepithelial neoplasia (HGIN), and EC. Information on participants' exposure to risk factors was collected. GAD was assessed with Generalized Anxiety Disorder Scale-7.

RESULTS

With esophageal endoscopy, 25,650 participants in ECHRRs were examined, 9586 of whom were suspicious and confirmed by esophageal pathology. The detection rate of EC and precancerous lesions was 6.83% (1751/25,650), with 1377 LGIN (5.37%), 272 HGIN (1.06%), and 102 EC (0.40%) cases. The overall mean GAD score (95% CI) and prevalence among 25,650 participants with endoscopy were 1.96 (1.93-1.99) and 16.90%, respectively. The mean GAD score and prevalence among 9586 participants with pathology were 1.96 (1.91-2.02) and 17.98%, respectively. The mean GAD scores of patients confirmed with normal, esophagitis, LGIN, HGIN, and EC were 1.73 (1.62-1.85), 1.91 (1.85-1.97), 1.94 (1.80-2.08), 3.98 (3.73-4.23). and 2.97 (2.49-3.45), respectively (p < 0.001). The corresponding prevalence of GAD were 5.21%, 18.72%, 17.72%, 43.75%, and 36.27%, respectively (p < 0.001). The age- and gender-adjusted odds ratios (ORs) between GAD and each esophageal lesion type were 1.02 (0.99-1.04), 1.01 (0.98-1.04), 1.27 (1.21-1.33), and 1.16 (1.08-1.24), respectively. The ORs (95% CIs) of the positive associations were 1.08 (1.05-1.12), 1.03 (0.99-1.07), 1.35 (1.29-1.42), and 1.19 (1.10-1.29) after further adjustment for potential confounders (all p < 0.001). Sensitivity analysis showed that the positive association persisted.

CONCLUSIONS

GAD was significantly higher in patients with EC and precancerous lesions. Focusing on and alleviating anxiety in high-risk groups (including patients with HGIN and EC) may be an effective strategy for EC prevention and control. Further prospective studies are warranted to validate the results.

Prevalence of skin picking (excoriation) disorder

Skin picking (excoriation) disorder is a mental health condition characterized by repetitive picking of one's skin leading to tissue damage as well as functional impairment and/or distress. A convenience sampling of 10,169 adults, aged 18-69 years, representative of the general US population, completed a survey to establish occurrence of skin picking disorder. 213 participants (2.1%) (55.4% female) identified as having current skin picking disorder and 318 (3.1%) (54.1% female) reported lifetime skin picking disorder (i.e. current or past). Those with current skin picking disorder were significantly more likely to be female compared to those who never had skin picking (Likelihood Ratio, LR chi-square = 31.705, p < 0.001). Mental health comorbidities were common with generalized anxiety disorder (63.4%), depression (53.1%), and panic disorder (27.7%) being the most frequently endorsed. This study suggests that skin picking disorder is relatively common in the general population and typically characterized by high rates of comorbidity.
