Prevalence of Mental Disorders among Older Chinese People in Tianjin City

The association between satisfaction with life and anxiety symptoms among Chinese elderly: a moderated mediation analysis

BACKGROUND

Previous studies have suggested that certain personal psychological variables (e.g., life satisfaction and cognitive function) and physical variables (e.g., body mass index [BMI]) are significantly associated with individuals' anxiety symptoms. However, relevant research on elderly is lagging and no studies have yet investigated the combined impact of these variables on anxiety. Thus, we conducted the present study to investigate the potential moderator role of BMI and the potential mediator role of cognitive function underlying the relationship between life satisfaction and anxiety symptoms in Chinese elderly based in Hong Kong.

METHODS

Sixty-seven elderly aged 65 years old and above were recruited from the local elderly community centres in this pilot study. Each participant underwent a systematic evaluation using the Satisfaction with Life Scale (SWLS), Hong Kong Version of the Montreal Cognitive Assessment (HK-MoCA), and the Hamilton Anxiety Rating Scale (HAM-A) and were measured for their body weight and height. Regression analysis using the bootstrapping method was employed to test the hypothesized moderated mediation model.

RESULTS

Our findings demonstrated the overall model accounted for 23.05% of the variance in scores of HAM-A (F (8, 57) = 2.134, p = 0.047) in Chinese elderly. There was a significant association between life satisfaction and anxiety symptoms (p = 0.031), indicating that individuals with higher life satisfaction were associated with less anxiety symptoms. Moreover, this relationship was positively moderated by BMI (b = 0.066, 95% CI [0.004, 0.128]), especially in Chinese elderly with BMI at a lower level (b = -0.571, 95% CI [-0.919, -0.224]) and an average level (b = -0.242, 95% CI [-0.460, -0.023]). No significant mediator role was detected for cognitive function (b = -0.006, 95% CI [-0.047, 0.044]) in our model.

CONCLUSIONS

Our findings suggest that increased life satisfaction can reduce anxiety symptoms among Chinese elderly as their BMI decreases (when BMI ranged between "mean - 1SD" and "mean" of the population). The significant interaction between psychological and physical factors underlying anxiety symptoms found in this study, presents a promising opportunity for translation into multi-level psychological and physical interventions for the management of anxiety in ageing patients during clinical practice.

Prevalence of depression and anxiety in older people in low- and middle- income countries in Africa, Asia and South America: A systematic review and meta-analysis

BACKGROUND

There is rapid growth of older people in Low- and Middle- Income Countries (LMICs). The aim of this review was to assess the literature on prevalence of anxiety and depression in this demographic, which to our knowledge, has not yet been conducted.

METHODS

Databases including Medline, PsychInfo, Embase, Scielo and African Journals Online were searched for terms including "mental disorders", "neurotic disorders", "mood disorders" and "anxiety disorders". Studies published between 1990 and 2020 providing data on older people (≥50 years) in LMICs (defined by World Bank Criteria) were included and quality-assessed. Meta-analysis was conducted on a subset of higher-quality studies to derive pooled prevalence estimates of depression.

RESULTS

One hundred and forty relevant studies were identified, of which thirty-two were included in meta-analysis. One hundred and fifteen studies reported depression prevalence only, 19 reported both depression and anxiety, and six reported anxiety only. In all studies identified, depression prevalence ranged from 0.5 % to 62.7 %, and Generalised Anxiety Disorder prevalence ranged from 0.2 % to 32.2 %. The pooled prevalence of depression on meta-analysis was 10.5 % (95 % CI, 8.9 % - 11.2 %). Reported prevalence rates of depression were significantly different in studies using ICD-10 compared with DSM criteria, and between community and clinical settings.

LIMITATIONS

The search strategy contained bias towards English language papers and high income country (HIC) publications. There is significant heterogeneity within the meta-analysis.

DISCUSSION

A wide range of methodologies and clinical criteria are used in prevalence studies of depression and anxiety in older people. Studies using screening tools found higher prevalence rates; clinicians and researchers should ensure diagnosis is made with gold-standard clinical criteria. Meta-analysis data suggest that rates of depression are similar in older people in LMICs compared to HICs but mental healthcare resources are limited, suggesting a large potential treatment gap.

Psychiatric Morbidity Among Older Hospitalized Patients

Background

Globally, life expectancy is increasing, leading to an equal proportion of elderly and young individuals, which carries extensive implications. In Bosnia and Herzegovina (BiH), the average age at death in 2021 was 77 years, positioning BiH in the middle of the global list of average life expectancy. Current studiesinvestigate whether the prevalence of psychiatric disorders increases or decreases with age, but results are inconsistent regarding the role of age.There is no prior research on mental disorders in the elderly population in BiH. The experience of the previous war in BiH and the post-war complex "transitional period" have been associated with specific challenges to the mental health of this population, inspiring our research topic.

Objective

The aim of this study was to investigate the psychiatric morbidity in hospitalized individuals aged≥55 years.

Methods

The sample consisted of all patients over age 55 treated at the Department of Psychiatry in Tuzla between January 2018 and December 2020 (N=637), divided into four age categories. Data were obtained from medical records, and for research purposes, a specific questionnaire was constructed.

Results

The predominant psychiatric morbidity stemmed from the category of affective disorders, most common within the "55-64 years" age group, while organic mental disorders were more prevalent in other age groups.Substance use disorders were present in patients aged "55-64 years", with a sharp decline in their prevalence in older age. Female participants had a significantly higher prevalence of affective, psychotic, neurotic, and stress-related disorders, whereas male participants exhibited an increased prevalence of organic mental and substance use disorders.

Conclusion

In total sample, the most prevalent diagnoses belong to the category of affective disorders. Female were most frequently diagnosed with affective disorders, whereas organic mental disorders and substance use disorders prevail in male.

Prevalence of mental disorders in the elderly population 5 years after the Lushan earthquake in Ya'an, China

PURPOSE

This study aimed to explore the prevalence and distribution of mental disorders in the elderly population 5 years after the Lushan earthquake in Ya'an, China.

METHODS

A multi-stage, group-matching random sampling method was adopted with 2579 elderly participants (≥ 60 years old) who were interviewed from January to May 2019. Preliminary screening was conducted using the scale by trained psychiatric nurses, followed by a diagnostic interview during the second stage using Chinese Version of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorder by trained psychiatrists.

RESULTS

A total of 2561 participants were included in this study with complete data. The weighted lifetime prevalence of all mental disorders in the elderly was 16.2% (95% CI 15.3-17.1), and the weighted 12-month prevalence was 15.2% (95% CI 13.4-17.0). Depressive disorders, anxiety disorders, substance-related and addictive disorders were the most common mental disorders. The 12-month prevalence of all mental disorders were significantly higher in the elderly living alone, with chronic somatic disease, and being poor (P < 0.05). The 12-month prevalence of posttraumatic stress disorder (PTSD) was significantly higher in the elderly in extremely severely earthquake-affected areas (P < 0.001).

CONCLUSION

The results of this study show that mental health status of the elderly in Ya'an area differ by socio-economic development, geographical location, and natural disasters. The social and economic development characteristics, the impact of major natural disasters (e.g., earthquakes), and population characteristics should be combined to formulate strategies and interventions to promote the mental health of the elderly.

Association between quality of life, sleep quality and mental disorders in Iranian older adults

Aging as a major challenge can affect the development and growth of countries all around the world. This study aimed to identify the subgroups of the elderly based on the quality of life (Qol), sleep quality, and common mental disorders and assess the role of demographic characteristics on the membership of participants in each latent class. This cross-sectional study was conducted on 1064 people over the age of 60 years. The sample was selected through cluster sampling in northern Iran. All participants completed six sets of checklists and questionnaires. Data analysis was performed using latent class analysis. Three latent classes were identified; namely, (1) healthy (66.8%), (2) anxious and with poor sleep quality (28.6%), and unhealthy (4.6%). Being Female significantly increased the odds of membership in classes 2 and 3 compared to class 1. Furthermore, living in urban areas increased the odds of belonging to class 2 and class 3 compared to class 1. Illiteracy was also shown to increase the odds of being in class 3 in comparison to class 1. Results from the present indicate that the co-occurrence of health problems in 33.2% of the elderly was observed in various forms. The results of this study can be used in prioritizing health programs for the elderly and emphasizing high-risk groups.

Depression and Quality of Life in Patients with Gliomas: A Narrative Review

In patients with gliomas, depression is a common complication that may cause severe psychological barriers and deteriorate the patient’s quality of life (QoL). Currently, the Hospital Anxiety and Depression Scale (HADS) is the most commonly used tool to diagnose depression in patients with gliomas. Female sex, unmarried status, low education level, high tumor grade, and a history of mental illness may increase the risks of depression and depressive symptoms in patients with gliomas. The QoL of patients with gliomas can be directly reduced by depression. Therefore, the evaluation and intervention of mood disorders could improve the overall QoL of patients with gliomas. Antidepressant use has become a treatment strategy for patients with gliomas and comorbid depression. This narrative review summarizes the current issues related to depression in patients with gliomas, including the prevalence, risk factors, and diagnostic criteria of depression as well as changes in QoL caused by comorbid depression and antidepressant use. The purpose of this review is to guide clinicians to assess the psychological status of patients with gliomas and to provide clinicians and oncologists with a new treatment strategy to improve the prognosis of such patients.

Prevalence, Structure, and Risk Factors for Mental Disorders in Older People

This review focuses on assessing the prevalence and risk factors of mental disorders in older people in the modern era, including the COVID-19 pandemic. A systematic review of the literature was conducted in PubMed, Elsevier, and Google using keywords over the past 10 years. Substantial discrepancy of data on the prevalence of psychiatric disorders has been shown in the elderly population. The significant incidence of mental disorders among nursing home residents is highlighted. The relevance of nonpsychotic depressive and anxiety disorders is demonstrated for the elderly, along with the difficulty of diagnosing mental disorders associated with physical pathology and cognitive impairments. The risk factors for mental disorders in older adults are socio-demographic but also economic, psychological, and physical. The problem of mental health of the elderly is characterized for the conditions of the COVID-19 pandemic associated with specific risk factors for psychiatric disorders. The shortage of evidence-based research in the treatment of mental disorders in the elderly and the urgency to improve the organization of psychiatric care for such patients are noted. Understanding the structure and prevalence of mental disorders among the elderly will allow optimizing the functioning of healthcare systems.

Lifetime and 1-Month Prevalence of Mental Disorders in Hebei Province, China: A Community-Based Cross-Sectional Study

Background: The prevalence of mental disorders is an important topic, which has been reported in different countries in the world. In China, some studies were also conducted to get the prevalence of mental disorders at the national level and in some metropolitan cities. However, the prevalence of mental disorders in Chinese underdeveloped provinces has not been reported internationally in recent decades. Due to the discrepancy in the social-economic development of different Chinese provinces, we also have reasons to believe the different prevalence of mental disorders between underdeveloped provinces and other provinces. Method: A community-based cross-sectional study was conducted among community residents aged 18 years and older in Hebei province, China. We screened 20,884 community residents in this study, and a Structured Clinical Interview for Diagnostic and Statistical Manual (DSM-IV) Axis I disorders was used to make the diagnoses of mental disorders. Results: The weighted lifetime prevalence of mental disorders was 15.87% (95% CI 15.38-16.38%), and the 1-month prevalence was 10.79% (95% CI 10.37-11.22%). Anxiety disorder ranked first in the classification of mental disorders for both lifetime (6.56%) and 1-month prevalence (6.25%). The weighted lifetime and 1-month region-gender-age-specific prevalence of mental disorders was also analyzed in this study. Conclusions: Mental disorders have been an important issue in Chinese economically underdeveloped regions, and the prevalence was at a high level compared with the results in the 2000s. There are several serious challenges in the work of Chinese mental disorders, which should be paid more attention to.

Art Therapy: A Complementary Treatment for Mental Disorders

Art therapy, as a non-pharmacological medical complementary and alternative therapy, has been used as one of medical interventions with good clinical effects on mental disorders. However, systematically reviewed in detail in clinical situations is lacking. Here, we searched on PubMed for art therapy in an attempt to explore its theoretical basis, clinical applications, and future perspectives to summary its global pictures. Since drawings and paintings have been historically recognized as a useful part of therapeutic processes in art therapy, we focused on studies of art therapy which mainly includes painting and drawing as media. As a result, a total of 413 literature were identified. After carefully reading full articles, we found that art therapy has been gradually and successfully used for patients with mental disorders with positive outcomes, mainly reducing suffering from mental symptoms. These disorders mainly include depression disorders and anxiety, cognitive impairment and dementias, Alzheimer's disease, schizophrenia, and autism. These findings suggest that art therapy can not only be served as an useful therapeutic method to assist patients to open up and share their feelings, views, and experiences, but also as an auxiliary treatment for diagnosing diseases to help medical specialists obtain complementary information different from conventional tests. We humbly believe that art therapy has great potential in clinical applications on mental disorders to be further explored.

Childhood familial environment and adulthood depression: evidence from a Chinese population-based study

BACKGROUND

Mental disorders have become an important public health issue and evidence is lacking on the impact of childhood experience on adulthood mental health in regions of low and middle income. Using national representative data from the China Health and Retirement Longitudinal Study, we aimed to explore the impact of childhood familial environment on adulthood depression.

METHODS

A total of 19 485 subjects were interviewed. The survey collected information on demographic variables, variables of childhood familial environment and potential pathway variables, including childhood health status, adulthood physical health status, adulthood social support and adulthood socio-economic status (SES). Depressive symptoms were measured by the 10-item version of the Center for Epidemiological Studies Depression Scale.

RESULTS

Parents' physical and mental health during the subjects' childhood were significantly associated with adulthood mental health. Mothers' smoking, unfair treatment and low family SES were associated with higher depressive symptoms in adulthood. Childhood physical and mental health status, adulthood physical health and adulthood SES might be important mediators in the pathways of childhood familial environment affecting adulthood depressive symptoms.

CONCLUSIONS

This study is the first to explore the relationship of childhood familial environment and adulthood depression in China. The results indicate that parents' physical and mental health, health behaviour and treatment equity among children a important predictors for adult depression.

Brain features of nearly drug-naïve female monozygotic twins with first-episode schizophrenia and the classification accuracy of brain feature patterns: A pilot study

BACKGROUND

Data on differences in brain features between monozygotic (MZ) twins with and without schizophrenia are scarce.

METHODS

We compared brain features of female MZ twins with and without first-episode schizophrenia and healthy controls (n = 20 each). Voxel-based morphometry and tract-based spatial statistics were used to analyze differences in brain structure. Whole-brain effective connectivity (EC) and functional connectivity (FC) networks were constructed using resting-state functional magnetic resonance imaging (rs-fMRI) data.

RESULTS

Female twins with schizophrenia exhibited abnormal gray matter volume (GMV) in the basal ganglia and prefrontal and parietal cortices, impairments in the arcuate fasciculus, and significant disruptions (primarily decreases) in nine EC networks. They exhibited rs-EC alterations involving the limbic areas and subcortex. Combined rs-EC and rs-FC data distinguished twins with first-episode schizophrenia with high accuracy. Combined consideration of structural and functional features enabled the distinction of female MZ twins with schizophrenia from those without schizophrenia and healthy controls with 100% accuracy.

CONCLUSIONS

Female MZ twins with schizophrenia exhibited increased GMV, white matter impairment, and disruptions in EC and FC networks. The combination of rs-EC + rs-FC data could distinguish female twins with schizophrenia from twins without schizophrenia and healthy controls with 97.4% accuracy, and the addition of structural brain features yielded a 100% accuracy rate. These findings may provide pivotal insight for further study of the mechanisms underlying schizophrenia.

The health effect of perceived built environment on depression of elderly people in rural China: Moderation by income

This study explored the health effect of perceived built environment on depression of the Chinese elderly people in rural areas. A multifaceted approach in examining perceived built environment was used. A sample of 670 older residents in rural area of China were interviewed, and data were collected mainly for exploratory factor analysis, confirmatory factor analysis and moderation analysis. Results showed a reliable construct of perceived built environment which was developed by this study. A significant moderating role of personal income per month in the significantly negative relationship between perceived built environment and depression was confirmed. That is, the health effect of perceived built environment on depression became weakened among people of higher income levels. This study added evidence for the health effect of perceived built environment on depression among Chinese elderly people. Additionally, individual income was identified as an important influencing factor in such effect. Discussion on the negative relationship between perceived built environment and depression, as well as the moderating effect of personal income in such relationship were presented.

Prevalence of cognitive dysfunction, psychological morbidity and abuse in the community-based elderly population in India

BACKGROUND

The elderly population in India is expected to grow enormously by 2050 owing to an increase in life expectancy. Community-based data on the prevalence of psychological morbidity, abuse and cognitive dysfunction are scarce.

AIMS

To determine the prevalence of cognitive dysfunction, psychological morbidity and abuse in the elderly population in a resettlement colony from East Delhi, India.

METHODS

A cross-sectional study was conducted on the elderly population of a resettlement colony, in East Delhi, comprising 5 blocks and 12 subblocks with a total population of 65 000. The study was carried out within 2 months from April to August 2017. The self-reported questionnaires were administered to detect cognitive dysfunction, psychological morbidity, social support and pattern of abuse.

RESULTS

The mean age of the study subjects was 70.29 years (53.8% were males, 78.8% were married, 86.9% were Hindus and 75% were living with children). A total of 106 subjects (66.6%) belonged to the lower socioeconomic strata with 120 (75%) living with children. Most of the subjects (70.6%) studied below the primary level of education. As detected on Goldberg General Health Questionnaire-12, 56.9% of the subjects had psychological morbidity. On Dementia Assessment by Rapid Test, 33.1% of subjects were screened positive. The pattern of abuse reported was as follows: emotional abuse (16.9%), physical abuse (7.5%), sexual abuse (1.9%) and social neglect (18.1%). The social support score was found to be 46.22 (12.22).

CONCLUSION

The results of this community-based study signify that appropriate steps at the policy level need to be undertaken so that abuse as well as neglect can be prevented. In addition, screening the elderly population helps to detect early cognitive dysfunction, psychological morbidity, abuse victims and individuals with poor support.

Validation of Global Self-Rated Health and Happiness Measures Among Older People in the Yilan Study, Taiwan

Background: Single-item measures of physical and mental health are feasible for older adults, but their validity for that age group is unclear. This study tested validity of a global self-rated health and a global self-rated happiness measure in a large sample of community-dwelling older adults in Taiwan.

Methods: A cross-sectional sample of 3,982 men and women aged 65 or older in Yilan, Taiwan, provided data on global self-rated health and happiness using 100-point numerical scales. The Physical Component Summary of the 12-Item Short Form Health Survey (version 2) and the Groningen Activity Restriction Scale were used to test the validity of the self-rated health item. The Mental Component of that 12-item scale and the Hospital Anxiety and Depression Scale were validators regarding the self-rated happiness item. Criterion validity was tested using the 12-Item Short Form Health Survey (version 2).

Results: The correlations between the self-rated health and happiness measures and the 12-Item Short Form Health Survey (version 2) validators were positive and statistically significant, supporting convergent validity. Sufficient divergent validity was demonstrated through the negative and significant relationship between the self-rated health item and the Groningen Activity Restriction Scale scores and the negative and significant relationship between the self-rated happiness item and the Hospital Anxiety and Depression Scale. Optimal cut-off scores for physical and mental health states depended on age and gender.

Conclusion: The global self-rated health and happiness measures were validated. Cut-off scores for evaluating older adults' physical and mental health should be age- and gender-specific.
