Exploring the association between depression and shenjing shuairuo in a population representative epidemiological study of Chinese adults in Guangzhou, China

Are neurasthenia and depression the same disease entity? An electroencephalography study

BACKGROUND

The neurasthenia-depression controversy has lasted for several decades. It is challenging to solve the argument by symptoms alone for syndrome-based disease classification. Our aim was to identify objective electroencephalography (EEG) measures that can differentiate neurasthenia from major depressive disorder (MDD).

METHODS

Both electronic medical information records and EEG records from patients with neurasthenia and MDD were gathered. The demographic and clinical characteristics, EEG power spectral density, and functional connectivity were compared between the neurasthenia and MDD groups. Machine Learning methods such as random forest, logistic regression, support vector machines, and k nearest neighbors were also used for classification between groups to extend the identification that there is a significant different pattern between neurasthenia and MDD.

RESULTS

We analyzed 305 patients with neurasthenia and 45 patients with MDD. Compared with the MDD group, patients with neurasthenia reported more somatic symptoms and less emotional symptoms (p < 0.05). Moreover, lower theta connectivity was observed in patients with neurasthenia compared to those with MDD (p < 0.01). Among the classification models, random forest performed best with an accuracy of 0.93, area under the receiver operating characteristic curve of 0.97, and area under the precision-recall curve of 0.96. The essential feature contributing to the model was the theta connectivity.

LIMITATIONS

This is a retrospective study, and medical records may not include all the details of a patient's syndrome. The sample size of the MDD group was smaller than that of the neurasthenia group.

CONCLUSION

Neurasthenia and MDD are different not only in symptoms but also in brain activities.

A WHO digital intervention to address depression among young Chinese adults: a type 1 effectiveness-implementation randomized controlled trial

Common mental disorders among young people are rising globally. Current university-based interventions are inadequate to address the need for evidence-based interventions. We investigated the effectiveness and implementation of Step-by-Step (SbS), a WHO digital intervention to address depression, among Chinese university students with depressive symptoms. In this paper, we report a type 1 hybrid effectiveness-implementation randomized controlled trial conducted between September 2021 and September 2022. The control condition was enhanced treatment as usual (ETAU, psychoeducation). The primary outcome was improvement in depression symptoms. Secondary outcomes were improvements in psychological well-being, anxiety symptoms, and self-identified psychosocial problems. Effectiveness of the intervention was evaluated using generalized linear mixed models. Implementation outcomes were evaluated by thematic analysis of participant interviews. A total of 371 participants were enrolled to two treatment conditions in a 1:1 ratio. SbS resulted in a greater reduction in depressive symptoms at posttreatment (p = 0.004, Hedges' g = 0.35), but no significant difference between SbS and ETAU was observed at three-month follow-up (p = 0.179, Hedges' g = 0.16). The treatment effect was larger among those who adhered to the treatment (Hedges' gs = 0.59 and 0.30). Subjective well-being also improved for SbS at both time points (Hedges' gs = 0.31 and 0.30). In addition, SbS resulted in more improvement in anxiety symptoms at posttreatment (p = 0.029, Hedges' g = 0.26), but not at three-month follow-up (p = 0.265, Hedges' g = 0.13). The qualitative results demonstrated that the intervention was well-implemented as a self-help mental health service, with minimal support from peer supporters. In conclusion, Step-by-Step, a digital intervention developed by WHO, was effective in reducing depressive symptoms in the short term and improving psychological well-being in a longer term. The sustained effect on depression needs further investigation. Improving uptake and engagement in the program is needed for its scale-up implementation as a university-based mental health service for Chinese young adults. Trial registration: ChiCTR2100050214.

Associations between depression, oxidative stress, and semen quality among 1,000 healthy men screened as potential sperm donors

OBJECTIVE

To explore the association between depression and semen quality and the mediating role of oxidative stress.

DESIGN

Cross-sectional study with repeated measures of semen quality.

SETTING

Human Sperm Bank of Hubei Province, People's Republic of China.

PATIENT(S)

From April 2017 to July 2018, we recruited 1,000 potential sperm donors who completed the Beck Depression Inventory questionnaire and had measures of oxidative stress biomarkers.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Severity of depression was evaluated by the Beck Depression Inventory scores (0-4, no depression; 5-13, mild depression; 14-20, moderate depression; and 21 or greater, severe depression). The urinary concentrations of 8-hydroxy-2-deoxyguanosine, 4-hydroxy-2-nonenal-mercapturic acid, and 8-iso-prostaglandin F_2α (8-isoPGF_2α) were measured to reflect oxidative stress status. Repeated semen quality parameters (n = 5,880) were examined by trained professional technicians according to the World Health Organization laboratory manual. Associations between depression, oxidative stress, and repeated measures of semen quality parameters were evaluated using linear or mixed-effects models with adjustment for potential confounders. Mediation analysis was performed to test the potential mediating role of oxidative stress.

RESULT(S)

A total of 391 (39.1%) men were classified as mild depression, 67 (6.7%) as moderate depression, and 19 (1.9%) as severe depression. Inverse dose-response relationships between severity of depression and semen quality parameters were found. Compared with men without depression (n = 523), those with severe depression had a 25.26% (95% confidence interval, -38.65%, -8.93%) lower semen volume, 37.04% (-55.37%, -11.20%) lower total sperm count, 13.57% (-23.17%, -2.78%) lower total motility, and 15.08% (-25.09%, -3.72%) lower progressive motility; men with moderate depression also had a 12.28% (-21.16%, -2.40%) lower semen volume and 23.56% (-36.50%, -7.97%) lower total sperm count. We found a positive dose-response relationship between severity of depression and urinary 8-isoPGF_2α concentrations. However, we found no evidence that the associations between depression status and semen quality were mediated by oxidative stress markers.

CONCLUSION(S)

In the study of Chinese male sperm donors, men with depression had worse semen quality parameters, including semen volume, sperm concentration, total sperm count, total motility, and progressive motility. Although depression was positively associated with urinary 8-isoPGF_2α concentrations, depression-semen quality associations were not mediated by oxidative stress.

Mental health on the move: An observational study to characterize post-migration depression symptoms among migrants from Sub-Saharan Africa in China

OBJECTIVE

Migrants from Sub-Saharan Africa to China faced challenges in accessing healthcare. Less is known about their depression prevalence. We aim to address this gap by providing an initial estimation on symptoms indicative of depression.

METHODS

A cross-sectional survey was conducted from August to October in 2019. Eligibility was defined as being originally from a Sub-Saharan African country and cumulative residence in China for at least one month. A convenience sample was drawn from snowball sampling online and venue-based sampling by community outreach. The primary outcome, symptoms indicative of depression, were measured by the Centre for Epidemiologic Studies Depression Scale using 16 as the cutoff. Multivariable logistic regressions were employed to examine the association between depression symptoms and their migration-related correlates. Data were analyzed using SAS 9.4.

RESULTS

The prevalence of symptoms indicative of depression assessed by CES-D was high at 44% among 928 participants when using 16 as a cutoff. Depression symptoms were associated with unsatisfactory housing conditions (aOR: 1.7, 95%CI: 0.8 to 3.3) and perception of very unfriendly attitudes from the local people (aOR: 4.5, 95%CI: 1.2 to 16.1) after adjusting for covariates.

CONCLUSIONS

Depression symptoms were prevalent among SSA migrants in China and warrants attention and intervention. Support should be provided during the post-migration period in China to mitigate depression risks. Future studies are needed to build more evidence on SSA migrants' mental health and to inform global health policies and programming.

Health service utilisation among African migrants in China: a nationwide cross-sectional study

OBJECTIVES

To assess the health utilisation status and associated factors among African migrants in China.

DESIGN

A national cross-sectional study was conducted among African migrants in China in 2019.

SETTING

Participants were recruited online and offline to participate in a self-report survey. Online participants were recruited through WeChat across China, and offline participants were recruited in Guangzhou.

PARTICIPANTS

We recruited participants who were from an African country; had spent at least 1 month cumulatively in China; were at least 18 years old; were willing to provide informed consent. A total of 1025 participants were recruited online and offline, 19 of them were excluded due to invalid response and 1006 people were finally included in the analysis.

OUTCOME MEASURES

The primary outcome was health service utilisation and associated factors among African migrants during their stay in China in the past 12 months. The potential factors include the predisposing factors (demographic characteristics and social structure variables), enabling factors (annual income, health insurance in China) and need factors (non-communicable chronic and infectious diseases, depression) which determined by Anderson framework were measured.

RESULTS

Eight hundred and seven online and 218 offline participants completed the survey, including 624 males and 382 females, with an average age of 26.4±8.9 years. Around 28.5% reported health utilization in the past 12 months. Results showed that longer duration in China, migration to China for business (aOR=2.23, 95% CI:1.13-4.40) and study (aOR=5.00, 95% CI:2.74-9.11), living in apartment (aOR=2.59, 95% CI:1.62-4.14) or dormitory (aOR=3.22, 95% CI:2.17-4.80) in China, suffering from chronic diseases, communicable diseases, and greater depressive symptoms (aOR=1.91, 95% CI:1.42-2.56) facilitated health service utilization.

CONCLUSIONS

The healthcare service that African migrants received in China is low. The existing public health policies and intervention measures need to be improved to make health utilisation more accessible and feasible for African migrants.

Beyond the DSM-5 Diagnoses: A Cross-Cultural Approach to Assessing Trauma Reactions

Although trauma exposure is a global phenomenon, trauma reactions vary considerably across cultures. Western psychiatric diagnoses, such as posttraumatic stress disorder (PTSD), may be limited in capturing the breadth of trauma reactions in cross-cultural contexts. Instead, cross-cultural instruments should examine locally relevant reactions, such as idioms of distress and explanatory models of illness, and account for ongoing stress and adversity. This article explains the need for complementing traditional trauma assessment approaches, how to create culturally sensitive instruments, the style and stance of practicing cultural humility when administering instruments, how to account for ongoing trauma and adversity, and ways to incorporate findings into treatment. These steps can improve culturally sensitive and comprehensive trauma assessment to capture universal and culturally relevant trauma reactions.

Sleep Conditions Associate with Anxiety and Depression Symptoms among Pregnant Women during the Epidemic of COVID-19 in Shenzhen

BACKGROUND

Pregnant women often encounter psychiatric symptoms and declined sleep quality as pregnancy proceeds. The associations between sleep conditions and anxious and depressive symptoms among pregnant women remained to be investigated, particularly during the epidemic of COVID-19.

METHODS

An online cross-sectional survey on pregnant women was conducted at the time period of fast increasing cases of COVID-19 in Shenzhen. The Self-Rating Anxiety Scale (SAS) and the Patient Health Questionnaire (PHQ-9) were applied to detect anxious and depressive symptoms. Multivariable logistic regressions models were established to explore the associations of sleep conditions with psychological symptoms.

RESULTS

In total, 751 pregnant women were enrolled, with a mean age of 30.51 years (Standard deviation: 4.28). Overall, 82.7% of the respondents considered low risk of being infected by COVID-19. The prevalence of anxiety and depression symptoms during the epidemic of COVID-19 among pregnant women were 13.4% and 35.4%, respectively, but most of which were mild. Variables referred to poor sleep conditions were strongly associated with anxious and depressive symptoms, including random or late time of going to bed, difficulty in falling sleep, short sleep duration, and ordinary or poor subjective sleep quality.

LIMITATIONS

Non-random sample restricted generalization of our findings to the whole population of pregnant women.

CONCLUSIONS

Our research revealed a notable proportion of the pregnant women who exhibited mild anxiety and depression symptoms during the epidemic of COVID-19 in Shenzhen. Targeted interventions in improving sleep conditions might help alleviate gestational anxious and depressive symptoms.

The relationship between perceived stress and emotional distress during the COVID-19 outbreak: Effects of boredom proneness and coping style

The outbreak of a novel coronavirus (COVID-19) pandemic was a great threat to the physical and mental health of the general population. Our research aimed to investigate the relationship between perceived stress and emotional distress during the initial outbreak. Furthermore, potential risks and protective factors, i.e., coping and boredom proneness, of stress-related emotional distress were also explored. Data from 3233 participants in China were collected through an online survey platform during the initial outbreak of the COVID-19 from January 31 to February 9 in 2020. Results showed that higher perceived stress was associated with more emotional distress including depression, fear, compulsion-anxiety, neurasthenia, and hypochondria. Boredom proneness significantly and positively mediated the relationship between perceived stress and emotional distress. Moreover, coping style moderated the stress-emotional distress relationship, i.e., individuals who mainly adopted positive coping strategies suffered fewer symptoms of depression, compulsion-anxiety, and neurasthenia under stress, while negative coping strategies aggravated emotional distress. These results from the present study provide practical value for mental health intervention during the emergent public health events.

Structural validation of The Patient Health Questionnaire-9 (PHQ-9) among Filipina and Indonesian female migrant domestic workers in Macao: STRUCTURAL VALIDATION OF PHQ-9

Within diverse global populations, validated tools are needed to assess common mental disorders. The Patient Health Questionnaire-9 (PHQ-9) is one of the most commonly used depression screeners. However, the PHQ-9 has not been structurally validated among female migrant domestic workers (MDWs). Female MDWs constitute a population numbering 11.5 million, and commonly report depression. This study aimed to structurally validate the PHQ-9 among Filipina and Indonesian female MDWs in Macao Special Administrative Region of China. Participants were recruited using respondent driven sampling. Participants were adult female MDWs from The Philippines (N=1375) or Indonesia (N=367) and legally working in Macao. We used confirmatory factor analysis (CFA) to test five structural models of depression using all PHQ-9 items with the Filipina and Indonesian samples. We applied multi-group CFA to test measurement invariance across samples. A two-factor (cognitive/affective, somatic) model yielded the best fit within both samples, and the multi-group CFA demonstrated invariance across samples. The two-factor model best represents the factor structure of the PHQ-9 among Filipina and Indonesian female MDWs.

Prevalence and Socio-Demographic Correlates of Poor Mental Health Among Older Adults in Agricultural Areas of China

Objective: Poor mental health is associated with impaired social functioning, lower quality of life, and increased risk of suicide and mortality. This study examined the prevalence of poor general mental health among older adults (aged 65 years and above) and its sociodemographic correlates in Hebei province, which is a predominantly agricultural area of China. Methods: This epidemiological survey was conducted from April to August 2016. General mental health status was assessed using the 12-item General Health Questionnaire (GHQ-12). Results: A total of 3,911 participants were included. The prevalence of poor mental health (defined as GHQ-12 total score ≥ 4) was 9.31% [95% confidence interval (CI): 8.4-10.2%]. Multivariable logistic regression analyses found that female gender [P < 0.001, odds ratio (OR) = 1.63, 95% CI: 1.29-2.07], lower education level (P = 0.048, OR = 1.33, 95% CI: 1.00-1.75), lower annual household income (P = 0.005, OR = 1.72, 95% CI: 1.17-2.51), presence of major medical conditions (P < 0.001, OR = 2.95, 95% CI: 2.19-3.96) and family history of psychiatric disorders (P < 0.001, OR = 3.53, 95% CI: 2.02-6.17) were significantly associated with poor mental health. Conclusion: The prevalence of poor mental health among older adults in a predominantly agricultural area was lower than findings from many other countries and areas in China. However, continued surveillance of mental health status among older adults in China is still needed.

Traditional Chinese Medicine Jiuwei Zhenxin Granules in Treating Depression: An Overview

Depression is known as "Yu Zheng" in traditional Chinese medicine (TCM). Jiuwei Zhenxin granules (JZG) is a type of TCM. According to TCM theory, it nourishes the heart and spleen, tonifies Qi, and tranquilizes the spirit, and may also has effects in the treatment of depression. Here, we systematically reviewed recent basic and clinical experimental studies of JZG and depression, including studies of the pharmacological mechanisms, active ingredients, and clinical applications of JZG in depression treatment. This review will deepen our understanding of the pharmacological mechanisms, drug interactions, and clinical applications of TCM prescriptions and provide a basis for the development of new drugs in the treatment of depression.

Neurasthenia: tracing the journey of a protean malady

Neuresthenia has had its popularity waxing and waning over the years. This review article traces the path and trajectory of the concept of this disorder, how it changed and varied over time, to the current times, when it has been almost forgotten and the concept is heading towards oblivion. Although its place in the diagnostic systems is currently in question, neurasthenia is still part of professional conversations and practice. The concept of neurasthenia emerged at the intersections of clinical, cultural and sociological dimensions of society. A deeper examination of how neurasthenia was situated at the intersections of race, class and gender exemplifies how psychiatric diagnoses may reflect and shape societal biases. The neurasthenia label has all but disappeared from contemporary nosological frameworks, however, there is a proliferation of other disorders, e.g. chronic fatigue syndrome, fibromyalgia, that try to capture the experience of fatigue, pain, weakness, and distress even in the absence of clear-cut medical aetiologies. Only time will tell, if this concept has indeed been buried, or will rise as a phoenix in the years to come. Newer nervous fatigue syndromes are expected to emerge from the use of technology, screen time and the virtual world.

Prevalence and socio-demographic correlates of major depressive disorder in older adults in Hebei province, China

BACKGROUND

Major depressive disorder (MDD) is common among older adults. The epidemiology of MDD is greatly influenced by sociocultural and economic factors. This study examined the 1-month and lifetime prevalence of MDD and its socio-demographic correlates in older adults living in Hebei province, an agricultural area of China.

METHODS

Multistage, stratified, random sampling was administered between April and August 2016. The diagnosis of MDD was established with the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) Axis I Disorders.

RESULTS

A total of 3911 participants were enrolled. The 1-month and lifetime prevalence of MDD in older adults was 2.0% (95%CI: 1.6-2.4%) and 3.4% (95%CI: 2.8-4.0%), respectively. Multivariable logistic regression analyses revealed that female gender [P < 0.001, adjusted odds ratio (aOR) = 2.6, 95%CI: 1.53-4.53], presence of comorbid major medical conditions (P < 0.001, aOR = 4.8, 95%CI: 2.17-10.39) and family history of psychiatric disorders (P = 0.013, aOR = 3.4, 95%CI: 1.30-8.96) were independently and significantly associated with higher odds of MDD.

CONCLUSION

The prevalence of MDD in older adults in Hebei province, China, was lower than most findings in China and other countries. Nevertheless, continued surveillance of elderly depression in China along with the development of primary, secondary and tertiary preventative interventions for the elderly with MDD is indicated.

A Large Sample Survey of Tibetan People on the Qinghai-Tibet Plateau: Current Situation of Depression and Risk Factors

BACKGROUND

A depressive state is a negative emotional state characterized by abnormal dejection and unpleasant mood. Long-term depressive symptoms can result in psychological disorders such as depression. However, little is known about the depression status and risk factors of the Tibetan people on the Qinghai-Tibet Plateau.

OBJECTIVE

This study explores the depression status of the Tibetan people to better promote ethnic minorities' physical and mental health.

PARTICIPANTS AND SETTING

The Center for Epidemiologic Studies Depression Scale (CES-D) was administered to 24,141 Tibetan people from Yushu Prefecture; the average age was 34.33 years (SD = 9.18, range = 18-94 years).

MATERIALS AND METHODS

Participants completed questionnaires collecting demographic information and evaluating symptoms of depression.

RESULTS

The depression prevalence was higher at high altitudes, and there may be a significant positive correlation between depression rates and altitude. Significant differences were found for each demographic variable. Participants with depressive symptoms (scores ≥8) accounted for 52.3% of the total sample, and participants with depression (scores ≥14) accounted for 28.6%. The binary logistic regression results showed that alcohol drinkers, unmarried participants, participants with high self-assessed socioeconomic status, participants with a high income level, and those with a middle-school education were more likely to be depressed.

CONCLUSIONS

The results provide the first evidence that the prevalence of depression in Tibetans of the Qinghai-Tibet Plateau is higher than that in the general Chinese population and that reported in Western studies, a finding that may be related to cultural differences and chronic hypoxia caused by the high altitude. This paper offers insight into the mental health status of people living in plateau areas and provides a basis for formulating pertinent mental health policy.

The epidemiology of current depression in Macau, China: towards a plan for mental health action

PURPOSE

Macau is a Special Administrative Region in China that has experienced tremendous development in its gambling industry during its post-colonial years. To inform mental health planning, this study presents the first population estimates and correlates of the current depression in Macau.

METHODS

A population-representative sample of 1068 Macau Chinese citizens aged 18 or above responded to a household telephone survey in January, 2015. The Patient Health Questionnaire-9 measured the current depression. Logistic regression models assessed the association between depression and potential correlates.

RESULTS

Overall, 8.0% (95% CI 6.3-9.7) of persons reported the current depression. A higher but non-significant proportion of women reported depression than men (9.3 vs. 6.6%) and older women reported higher prevalence (13.4%) than other demographic groups. Persons who were unemployed (OR = 4.9, 2.3-10.5), separated or divorced (OR = 3.1, 1.1-8.9), and reported poor self-rated health (OR = 5.0, 2.8-9.0), low quality of life (OR = 6.2, 3.1-12.7), lower social standing (OR = 2.4, 1.4-4.0), lower community trust (OR = 1.9, 1.2-3.1), lower perceived fairness (OR = 2.3, 1.4-3.8), lower social cohesion (OR = 3.8, 2.3-6.2), and lower social integration (OR = 3.0, 1.9-5.0) had greater odds of depression than their comparison group.

CONCLUSIONS

The current study demonstrated the burden of depression among Macau adults disproportionately affects women during emerging adolescence and old age, and men during middle adulthood. Key strategies to improve mental health services in Macau are discussed.
