Prevalence and risk factors for depression in older people in Xi'an China: a community-based study

Ninjinyoeito Prevents Onset of Depression-Like Behavior and Reduces Hippocampal iNOS Expression in Senescence-Accelerated Mouse Prone 8 Mice

Late-life depression is a globally prevalent disorder. Ninjinyoeito (NYT), a traditional Japanese herbal medicine, attenuates depressive symptoms in older patients. However, the mechanisms underlying the antidepressive effect of NYT are unknown. In this study, we investigated the mechanism of the action of NYT using senescence-accelerated mouse prone 8 (SAMP8) mice, which exhibit accelerated aging. SAMP8 mice were treated with NYT starting at 12 weeks of age. Twelve-week-old SAMP8 mice did not show prolonged immobility time in the tail suspension test compared with age-matched SAMR1 mice (normal aging control). At 34 weeks of age, vehicle-treated SAMP8 mice displayed prolonged immobility time compared with SAMR1 mice. NYT-treated SAMP8 mice showed a shorter immobility time than that of vehicle-treated SAMP8 mice. Notably, NYT decreased hippocampal inducible nitric oxide synthase (iNOS) expression in SAMP8 mice. There was no difference in iNOS expression between SAMR1 and vehicle-treated SAMP8 mice. Subchronic (5 days) administration of an iNOS inhibitor, 1400 W, shortened the immobility time in SAMP8 mice. These results suggest that NYT prevents an increase in immobility time of SAMP8 mice by decreasing iNOS levels in the hippocampus. Therefore, the antidepressive effect of NYT in older patients might be mediated, at least in part, by the downregulation of iNOS in the brain. Our data suggest that NYT is useful to prevent the onset of depression with aging.

Association between chronic diseases and depression in the middle-aged and older adult Chinese population-a seven-year follow-up study based on CHARLS

Background

With the aging of the Chinese population, the prevalence of depression and chronic diseases is continually growing among middle-aged and older adult people. This study aimed to investigate the association between chronic diseases and depression in this population.

Methods

Data from the China Health and Retirement Longitudinal Study (CHARLS) 2011-2018 longitudinal survey, a 7-years follow-up of 7,163 participants over 45 years old, with no depression at baseline (2011). The chronic disease status in our study was based on the self-report of the participants, and depression was defined by the 10-item Center for Epidemiologic Studies Depression Scale (CES-D-10). The relationship between baseline chronic disease and depression was assessed by the Kaplan-Meier method and Cox proportional hazards regression models.

Results

After 7-years follow-up, 41.2% (2,951/7163, 95% CI:40.1, 42.3%) of the participants reported depression. The analysis showed that participants with chronic diseases at baseline had a higher risk of depression and that such risk increased significantly with the number of chronic diseases suffered (1 chronic disease: HR = 1.197; 2 chronic diseases: HR = 1.310; 3 and more chronic diseases: HR = 1.397). Diabetes or high blood sugar (HR = 1.185), kidney disease (HR = 1.252), stomach or other digestive diseases (HR = 1.128), and arthritis or rheumatism (HR = 1.221) all significantly increased the risk of depression in middle-aged and older adult Chinese.

Conclusion

The present study found that suffering from different degrees of chronic diseases increased the risk of depression in middle-aged and older adult people, and these findings may benefit preventing depression and improving the quality of mental health in this group.

Differential Associations Between Depressive Symptom-Domains With Anxiety, Loneliness, and Cognition in a Sample of Community Older Chinese Adults: A Multiple Indicators Multiple Causes Approach

Background and Objectives

Depressive symptoms are common in older adults, and often co-occur with other mental health problems. However, knowledge about depressive symptom-domains and their associations with other conditions is limited. This study examined depressive symptom-domains and associations with anxiety, cognition, and loneliness.

Research Design and Methods

A sample of 3,795 participants aged 60 years and older were recruited from the community in Hong Kong. They were assessed for depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]), anxiety (Generalized Anxiety Disorder 7-item), loneliness (UCLA 3-item), and cognition (Montreal Cognitive Assessment 5-Minute Protocol). Summary descriptive statistics were calculated, followed by confirmatory factor analysis of PHQ-9. Multiple Indicators Multiple Causes analysis was used to examine the associations between mental health conditions in the general sample and subgroups based on depressive symptom severity.

Results

A 4-factor model based on the Research Domain Criteria showed the best model fit of PHQ-9 (χ2/df = 10.63, Root-Mean-Square Error of Approximation = 0.05, Comparative Fit Index = 0.96, Tucker-Lewis Index = 0.93). After adjusting for demographics, 4 depressive symptom-domains were differentially associated with anxiety, loneliness, and cognition across different depression severity groups. The Negative Valance Systems and Internalizing domain (NVS-I; guilt and self-harm) were consistently associated with anxiety (β = 0.45, 0.44) and loneliness (β = 0.11, 0.27) regardless of depression severity (at risk/mild vs moderate and more severe, respectively, all p < .001).

Discussion and Implications

The consistent associations between the NVS-I domain of depression with anxiety and loneliness warrant attention. Simultaneous considerations of depressive symptom-domains and symptom severity are needed for designing more personalized care.

Estimating causal effects of physical disability and number of comorbid chronic diseases on risk of depressive symptoms in an elderly Chinese population: a machine learning analysis of cross-sectional baseline data from the China longitudinal ageing social survey

OBJECTIVE

This study aimed to explore the causal effects of physical disability and number of comorbid chronic diseases on depressive symptoms in an elderly Chinese population.

DESIGN, SETTING AND ANALYSIS

Cross-sectional, baseline data were obtained from the China Longitudinal Ageing Social Survey, a stratified, multistage, probabilistic sampling survey conducted in 2014 that covers 28 of 31 provincial areas in China. The causal effects of physical disability and number of comorbid chronic diseases on depressive symptoms were analysed using the conditional average treatment effect method of machine learning. The causal effects model's adjustment was made for age, gender, residence, marital status, educational level, ethnicity, wealth quantile and other factors.

OUTCOME

Assessment of the causal effects of physical disability and number of comorbid chronic diseases on depressive symptoms.

PARTICIPANTS

7496 subjects who were 60 years of age or older and who answered the questions on depressive symptoms and other independent variables of interest in a survey conducted in 2014 were included in this study.

RESULTS

Physical disability and number of comorbid chronic diseases had causal effects on depressive symptoms. Among the subjects who had one or more functional limitations, the probability of depressive symptoms increased by 22% (95% CI 19% to 24%). For the subjects who had one chronic disease and those who had two or more chronic diseases, the possibility of depressive symptoms increased by 13% (95% CI 10% to 15%) and 20% (95% CI 18% to 22%), respectively.

CONCLUSION

This study provides evidence that the presence of one or more functional limitations affects the occurrence of depressive symptoms among elderly people. The findings of our study are of value in developing programmes that are designed to identify elderly individuals who have physical disabilities or comorbid chronic diseases to provide early intervention.

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.

Decomposition and comparative analysis of differences in depressive symptoms between urban and rural older adults: Evidence from a national survey

OBJECTIVES

The aim of this study was to investigate the factors influencing urban-rural differences in depressive symptoms among old people in China and to measure the contribution of relevant influencing factors.

DESIGN

A cross-sectional research. The 2018 data from The Chinese Longitudinal Health Longevity Survey (CLHLS).

SETTING

Twenty-three provinces in China.

PARTICIPANTS

From the 8th CLHLS, 11,245 elderly participants were selected who met the requirements of the study.

MEASUREMENTS

We established binary logistic regression models to explore the main influencing factors of their depressive symptoms and used Fairlie models to analyze the influencing factors of the differences in depressive symptoms between the urban and rural elderly and their contribution.

RESULTS

The percentage of depressive symptoms among Chinese older adults was 11.72%, and the results showed that rural older adults (12.41%) had higher rates of depressive symptoms than urban (10.13%). The Fairlie decomposition analysis revealed that 73.96% of the difference in depressive symptoms could be explained, which was primarily associated with differences in annual income (31.51%), education level (28.05%), sleep time ( - 25.67%), self-reported health (24.18%), instrumental activities of daily living dysfunction (20.73%), exercise (17.72%), living status ( - 8.31%), age ( - 3.84%), activities of daily living dysfunction ( - 3.29%), and social activity (2.44%).

CONCLUSIONS

The prevalence of depressive symptoms was higher in rural than in urban older adults, which was primarily associated with differences in socioeconomic status, personal lifestyle, and health status factors between the urban and rural residents. If these factors were addressed, we could make targeted and precise intervention strategies to improve the mental health of high-risk elderly.

Global prevalence of depression in older adults: A systematic review and meta-analysis of epidemiological surveys

BACKGROUND

The reported prevalence of depressive symptoms (depression hereafter) among older adults varied widely across different studies. This was a meta-analysis to systematically examine the global prevalence of depression among older populations and its associated factors.

METHODS

A systematic literature search was performed in PubMed, EMBASE, PsycINFO, and Web of Science. Due to the differences in demographic and clinical characteristics between studies, random-effects model was used to calculate the pooled prevalence of depression and its 95% confidence interval (95% CI).

RESULTS

In total, 55 studies with 59,851 individuals met the study criteria and were included in the analyses. The overall prevalence of depression was 35.1% (95%CI: 30.2-40.4%). Subgroup analyses revealed that different sampling methods (Q=10592.49, p = 0.037), Geriatric Depression Scale versions (Q=13712.55, p < 0.001) and income levels (Q=14.028, P < 0.001) were significantly associated with the pooled prevalence of depression in older adults. In the meta-regression analyses, time of survey (B=0.012, z = 2.30, p = 0.029) was positively associated, and mean age (B=-0.018, z = 2.10, p = 0.044) was negatively associated with the prevalence of depression in older populations. The funnel plot and Egger's test did not reveal any significant publication bias (Egger's test: t = 1.93, p = 0.059).

CONCLUSION

This meta-analysis found that over a third of older populations globally had depression. Effective preventive measures, regular screening and timely interventions are needed to address this highly prevalent public health problem among older adults.

Prevalence and factors associated with depression among older adults in the case of a low-income country, Ethiopia: a systematic review and meta-analysis

BACKGROUND

Depression is among the common mental health problems in late-life and an important public health problem. Studies from both middle- and high-income countries have shown that depression is more common among older people than in adolescents. Many older people with depression are overlooked, and fewer efforts are made to mitigate their suffering. Despite depression being a major public health problem among older adults, its overall magnitude, and its main predictors were not determined for the development of appropriate measures. Hence, the objective of this study was, therefore, to estimate the overall prevalence of depression and identify its predictors among older adults in Ethiopia.

METHODS

Available articles were searched by means of different databases using the PRISMA guideline. The quality of the included studies was assessed using a JBI quality appraisal tool. STATA version 14.0 (STATA Corporation, College Station, Texas, USA) statistical software was used to analyze the eligible studies. Subgroup and sensitivity analyses were performed. Cochran's Q and the I2 test were used to assess heterogeneity. The presence of publication bias was evaluated by using Egger's test and visual inspection of the symmetry in funnel plots.

RESULT

In this meta-analysis, we included 11 articles that assessed 6521 older adults. The overall prevalence of depression among older adults in Ethiopia was 41.85 (33.52, 50.18). The finding was higher in the Oromia region with a prevalence of 48.07% (95% CI: 35.62, 60.51). The finding also demonstrated that being female (AOR = 1.76, 95% CI: 1.17, 2.63), no formal education (AOR = 1.82, 95% CI: 1.03, 3.19), with chronic diseases (AOR = 2.46, 95% CI: 1.00-6.06), and no social support (AOR = 2.01, 95% CI: 1.06, 3.83) were found to be independent predictors of depression in older Ethiopian adults.

CONCLUSION

Our systematic review and meta-analysis showed that almost two out of five older adults had depression. Female sex, no formal education, having chronic diseases, and no social support were the independent predictors of depression among older adults in Ethiopia. The study emphasizes that depression among older adults in Ethiopia calls for appropriate screening and interventions to reduce the occurrence and its overwhelming consequences.

Behavioral alterations, brain oxidative stress, and elevated levels of corticosterone associated with a pressure injury model in male mice

OBJECTIVES

Sustained stress can cause physiological disruption in crucial systems like the endocrine, autonomic, and central nervous system. In general, skin damages are physical stress present in hospitalized patients. Also, these pressure injuries lead to pathophysiological mechanisms involved in the neurobiology of mood disorders. Here, we aimed to investigate the behavioral alterations, oxidative stress, and corticosterone levels in the brain areas of mice submitted to the model of pressure injury (PI).

METHODS

The male mice behaviors were assessed in the open field test (OFT), elevated plus maze test (EPM), tail suspension test (TST), and sucrose preference test (SPT). Then, we isolated the prefrontal cortex (PFC), hippocampus (HP), and striatum (ST) by brain dissection. The nonprotein sulfhydryl groups (NP-SH) and malondialdehyde (MDA) were measured in the brain, and also the plasma corticosterone levels were verified.

RESULTS

PI model decreased the locomotor activity of animals (p<0.05). Considering the EPM test, the PI group showed a decrease in the open arm activity (p<0.01), and an increase in the closed arm activity (p<0.05). PI group showed an increment in the immobility time (p<0.001), and reduced sucrose consumption (p<0.0001) compared to the control groups. Regarding the oxidative/nitrosative profile, all brain areas from the PI group exhibited a reduction in the NP-SH levels (p<0.0001-p<0.01), and an increase in the MDA level (p<0.001-p<0.01). Moreover, the PI male mice presented increased levels of plasma corticosterone (p<0.05).

CONCLUSIONS

Our findings suggest that the PI model induces depressive and anxiety-like behaviors. Furthermore, it induces pathophysiological mechanisms like the neurobiology of depression.

An association between multi-morbidity and depressive symptoms among Indian adults based on propensity score matching

Keeping in view the cascade of disturbances caused by the co-existence of multi-morbidity and depression among aged population, this study aims to ascertain the independent impact of multi-morbidity as a risk factor for the development of depressive symptoms among adults living in India. The present study utilizes data from the nationally representative survey “Longitudinal Ageing Study in India” (LASI, Wave-1, 2017–2018). The eligible sample size was 62,244 adults aged 45 years and above. Descriptive statistics along with bivariate analysis was used to understand the prevalence of depressive symptoms. Further, binary logistic regression and Propensity Score Matching (PSM) methods were applied to examine the independent effect of multi-morbidity on depressive symptoms while controlling the selected background characteristics. Overall, around one-third respondents had at least one chronic disease and one-fifth had multi-morbidity. The most prevalent chronic disease reported in the sampled population was hypertension followed by diabetes and joint disease. It is observed that older adults with multiple chronic diseases had 77% higher odds of having depressive symptoms as compared to those without a history of chronic disease in the multivariable logistic regression model. Results obtained from PSM indicate that the risk of having depressive symptoms was 3.7% higher for adults with multi- morbidity. Depressive symptom was identified to be associated with a wider range of multiple physical health problems and people with multi-morbidity are at a higher risk of having depressive symptoms. It is imperative that multi-morbidity can be used as a screener for identifying people with depressive symptoms.

Hearing impairment, family financial support, and depressive symptoms among Chinese middle-aged and older adults

AIMS

Hearing impairment (HI) is prevalent among middle-aged and older adults, but few studies have examined its mental health consequences in China. This study investigated the association of HI with depressive symptoms and whether family financial support moderated the association among adults aged 45 in China.

METHODS

Data were obtained from three waves of the China Health and Retirement Longitudinal Study (2011, 2013 and 2015). Hearing impairment was defined as a self-reported hearing problem in one or both ears. Depressive symptoms were measured with CESD-10. Associations between HI and depressive symptoms were modeled using fixed-effect models.

RESULTS

People with self-reported hearing loss were more likely than those without hearing loss to have depressive symptoms, with an odds ratio of 1.25 [1.07-1.47]. The association remained significant after adjusting for socio-demographic characteristics, lifestyle behaviors, and health conditions. Family financial support moderated this association. Among those with HI, adults with a higher level of family financial support tend to have better performance on symptoms of depression.

CONCLUSIONS

HI was positively associated with depressive symptoms among adults aged ≥45 in China, and family financial support played a buffering role in the relationship between HI and depressive symptoms.

Task sharing and stepped referral model for community mental health promotion in low- and middle-income countries (LMIC): insights from a feasibility study in India

BACKGROUND

This study is a low-cost community mental health task-sharing model driven by university students to strengthen the mental health workforce in poor resource settings. This article presents the feasibility of a stepped referral model using the community health workforce and university students. The primary feasibility objective is to detect and refer people with mental illness from the community using a task-sharing approach.

METHODS

We tested the model using a cross-sectional, one-phase door-knock survey in three geographically defined locations in Kerala, India, between May and July 2019. Students surveyed 549 residents above 18 years of age who consented to participate in the study to detect depressive symptoms and suicidality. The feasibility of the current model was evaluated based on four criteria: (a) identification and deployment of untapped human resources, (b) coordination of community health resources, (c) the acceptability of stepped referral pathways, and (d) identification of implementation challenges.

RESULTS

The mean age of the participants was 38.8, and more than 62% of the respondents were women. The results showed that 11.29%, 8.38%, and 4.91% of people reported mild, moderate, and severe levels of depression, respectively, and suicidal thoughts were found in 6.9% and suicidal ideation in 1.8%. The odds of depression were higher among females compared to males (OR: 1.64 (0.75-2.52), poor people (OR: 2.01 (1.14-2.88), and people with chronic illnesses (OR: 2.03 (1.24-2.81). The agreement of the findings with professional-administered research validated the strategy's efficiency. Twenty-seven patients with severe/extreme degrees of depression were sent for high-intensity interventions led by the mental health team, whereas 135 individuals with mild and above depression were referred for low-intensity interventions.

CONCLUSIONS

The newly recruited mental health workforce-driven screenings were acceptable and effective in detecting mental illness in the community population. We tested the care coordination systems and processes in creating referral pathways for the detected patients. Further, task-sharing stepped referral model will be tested in five panchayats (the lowest tier of local self-government) before replicating the model across India through Unnat Bharat Abhiyan (UBA) scheme.

Relation between Noise Pollution and Life Satisfaction Based on the 2019 Chinese Social Survey

Noise pollution is a leading cause of decreasing well-being of residents in both developed and developing countries. Improving residents’ well-being measured by life satisfaction is a key goal of government policy. Individuals with high life satisfaction usually have positive emotions, life orientation, and codes of conduct, which are positive and beneficial for individuals, families, and society as a whole. In order to supplement relevant research and provide policy suggestions for individuals, government, and societies, this study explores the relationship between noise pollution and the life satisfaction of Chinese residents. Based on data from 4869 observations from the Chinese Social Survey in 2019, the effect of noise pollution on life satisfaction is estimated by using ordinary least squares and propensity score matching methods. The results show that noise pollution has a significant negative effect on Chinese life satisfaction. Moreover, the effect is heterogeneous depending on individuals’ education levels and ages. Finally, residents’ living environment satisfaction is shown to be the potential mechanism by which noise pollution affects life satisfaction.

Socioeconomic and health-related inequalities in major depressive symptoms among older adults: a Wagstaff's decomposition analysis of data from the LASI baseline survey, 2017-2018

OBJECTIVES

To find out the association between socioeconomic and health status and depression among older adults and explore the contributing factors in the socioeconomic and health-related inequalities in late-life depression.

DESIGN

A cross-sectional study was conducted using large representative survey data.

SETTING AND PARTICIPANTS

Data for this study were derived from the baseline wave of the Longitudinal Ageing Study in India conducted during 2017-2018. The effective sample size was 30 888 older adults aged 60 years and above.

PRIMARY AND SECONDARY OUTCOME MEASURES

The outcome variable in this study was depression among older adults. Descriptive statistics along with bivariate analysis was conducted to report the preliminary results. Multivariable binary logistic regression analysis and Wagstaff's decomposition were used to fulfil the objectives of the study.

RESULTS

There was a significant difference for the prevalence of depression (4.3%; p<0.05) among older adults from poor (11.2%) and non-poor categories (6.8%). The value of the Concentration Index was -0.179 which also confirms that the major depression was more concentrated among poor older adults. About 38.4% of the socioeconomic and health-related inequality was explained by the wealth quintile for major depression among older adults. Moreover, about 26.6% of the inequality in major depression was explained by psychological distress. Self-rated health (SRH), difficulty in activities of daily living (ADL) and instrumental ADL (IADL) contributed 8.7%, 3.3% and 4.8% to the inequality, respectively. Additionally, region explained about 23.1% of inequality followed by life satisfaction (11.2) and working status (9.8%) for major depression among older adults.

CONCLUSIONS

Findings revealed large socioeconomic and health-related inequalities in depression in older adults which were especially pronounced by poor household economy, widowhood, poor SRH, ADL and IADL difficulty, and psychological distress. In designing prevention programmes, detection and management of older adults with depression should be a high priority, especially for those who are more vulnerable.

Social support moderates the association of functional difficulty with major depression among community-dwelling older adults: evidence from LASI, 2017-18

BACKGROUND

This study aimed to examine the potential independent association of functional disability with major depression and moderating effects of social support variables including marital status, living arrangement and social participation in such associations.

METHODS

Data for the study were drawn from the Longitudinal Ageing Study in India (LASI) wave 1 that was collected during 2017-18 including a sample of 31,464 individuals aged 60 years and above. Descriptive statistics and results from bivariate analysis have been reported. Further, moderated multivariable logistic regression models were used to fulfil the study objective. Major depressive disorder was assessed using the scale of the Short Form Composite International Diagnostic Interview (CIDI-SF).

RESULTS

It was found that 8.67% of older participants were depressed in this study. Older adults who had difficulty in basic activities of daily living (BADL) (15.34%), difficulty in instrumental activities of daily living (IADL) (12.06%), unmarried (10.13%), separate living (9.67%) and socially inactive (10.09) were having higher prevalence of major depression compared to their respective counterparts. The adjusted model-1 revealed that older adults who had difficulty in BADL and IADL were 2.53 times [AOR: 2.53, CI: 2.17-2.95] and 2.27 times [AOR: 2.27, CI: 1.97-2.64] more likely to have major depression than those with no difficulty in BADL and IADL respectively. Further, interaction analyses found that currently unmarried status, separate living and being socially inactive have moderation effects in the observed associations and exacerbate the likelihood of major depression among older adults who are functionally impaired.

CONCLUSIONS

The findings highlight the importance of integrating social participation in the daily life of older adults and developing initiatives that promote a healthy surrounding such as social connectedness, co-residential living and special care for those who are physically disabled to protect against late-life depression.

Depressive Symptoms and ADL/IADL Disabilities Among Older Adults from Low-Income Families in Dalian, Liaoning

Purpose

This study aimed to assess the prevalence of depressive symptoms and ADL/IADL disabilities and explore their correlation and associated factors for depressive symptoms among community-dwelling older adults from low-income families in Dalian, Liaoning Province, China.

Methods

This cross-sectional study included 522 participants aged 60 years and older from low-income families in Dalian. The 30-Item Geriatric Depression Scale was employed to measure depressive symptoms. The Katz ADL Scale and IADL Scale were used to evaluate the performance of activities necessary for independent life. SPSS 22.0 was employed to analyze the data. Logistic regression was used to estimate the relationship between depressive symptoms and ADL/IADL disabilities in five models.

Results

The prevalence of depressive symptoms among older people from low-income families in Dalian was 57.3%. A total of 19.0% had difficulties performing ADLs, and 40.2% had difficulties performing IADLs. Logistic regression analysis revealed that ADL/IADL disabilities were associated with depressive symptoms even after controlling for people’s sociodemographic characteristics, welfare, health conditions and informal care. The following factors were associated with depressive symptoms: education, self-reported health, number of chronic diseases, and emotional support from families.

Conclusion

Given that older people from low-income families in Dalian have a notable prevalence rate of depressive symptoms, and ADL/IADL disabilities were independently associated with these symptoms, it is crucial to give priority to this particular group in geriatric health services due to economic and health disparities.

Stressful Life Events and Chinese Older People Depression: Moderating Role of Social Support

Aim: This study analyzes the effects of retrospective stressful life events on current depression among Chinese older people and how these effects are moderated by social support. Stressful life events comprise bereavement, divorce, health adversities, accidents, and financial losses due to fraud.

Data and Method: Data were drawn from the China Health and Retirement Longitudinal Study (CHARLS) of the 2015 panel, and responses from 9,619 older people aged over 60 years were used. The least-squares regression method was applied to measure the linear effects. Propensity score matching minimized selection bias and enabled the measurement of the net effects of stressful life events. The bias-corrected matching estimator was also used to correct the inexact matching bias from propensity score matching.

Result: Experienced stressful life events and exposure to cumulative stressful life events were found to lead to depression in older people. When older people experienced stressful life events but with more social activities, and higher satisfaction and frequent contact with children, their depressive levels were lower. The results of the propensity score matching showed that stressful life events resulted in depression in older people. Furthermore, individuals with family support were able to moderate stressful life events effects; however, the moderating effects of social activity separately were negligible. In sum, with the moderating role of family support and social activity, the average differences in older people depression caused by stressful life events decreased.

Conclusion: Experiencing stressful life events is detrimental to the psychological health of the older people. Social support, including family support and social activity, has buffered detrimental effects on depression caused by stressful life events.

Interpretations: The study underscores the need to supply effective interventions for the older people who experienced stressful life events. First, society should improve the capability of community care centers to supply mental health services. Second, family members should pay attention to mental condition of older people, and specific support should concord with the needs of Chinese older people. In addition, support suppliers can move from being confined to kinship relationships to close relationships, such as the community partners and neighbors.

Effects of Social Participation and Its Diversity, Frequency, and Type on Depression in Middle-Aged and Older Persons: Evidence From China

Background

Depression is one of the greatest public health problems worldwide. The potential benefit of social participation (SP) on mental health has been widely acknowledged. Nevertheless, a few studies have used propensity score matching (PSM) to reduce the influence of data bias and confounding variables. This study explored the effect of social participation on depression among middle-aged and older Chinese persons through a PSM method, considering the frequency, type, and quantity of SP. Effects were compared among different age groups, genders, and places of residence.

Methods

The datasets were obtained from the 2018 wave of the China Health and Retirement Longitudinal Study. A total of 9,404 respondents aged 45 and above were included in the study. PSM and ordinary least squares methods were used to estimate the effect of social participation on depression.

Results

PSM estimation results showed that SP had a significantly positive effect on decreasing depression scores (p < 0.001) by 0.875-0.898 compared with persons without SP. All types of SP had a significantly positive effect (p < 0.001), and participating in community activities had the largest effect (β = -1.549 to -1.788, p < 0.001). Higher frequency of participation and more types of SP promoted lower depression scores; subgroup analyses revealed that the promotion effect was significantly greater among women, those aged ≥75 years, and those living in urban areas.

Conclusion

PSM indicated that SP could alleviate the depression of middle-aged and older Chinese persons. Targeted measures should be adopted to promote SP and thereby improve mental health and promote healthy and active aging.

Factors associated with depression across age groups of older adults: The Singapore Chinese health study

OBJECTIVES

We studied sociodemographic and health factors associated with depression across three age groups of community-dwelling older adults.

METHODS/DESIGN

We used data from 16,785 participants from the third follow-up of the Singapore Chinese Health Study (mean age: 73, range: 61-96 years). We defined depression as having a score of ≥5 using the 15-item Geriatric Depression Scale. We used regression splines to examine the pattern of depression risk with age and applied multivariable logistic regression to study factors associated with depression.

RESULTS

Increasing age was associated with depression in an inverted J-shape relationship with the highest odds ratio (OR) at age 75. Compared to the youngest-old (<70 years), the middle-old (70-80 years) had higher odds of depression [OR = 1.20, 95% confidence interval (CI) = 1.09-1.31], while the oldest-old (>80 years) had no increased risk (OR = 1.01, 95% CI = 0.89-1.15). We also found demographic (men, lower education, unemployment), social (living alone, poor social support, no social activity) and health factors (instrumental limitations, poor physical function, function-limiting pain, chronic diseases, cognitive impairment, poor sleep quality, poor self-rated health) associated with depression. In stratified analysis by age groups, the OR estimates for lower education level, instrumental limitations and cognitive impairment decreased with age, whereas the risk of depression for men increased with age (all p-values for interaction<0.03).

CONCLUSIONS

Compared to the youngest-old, the likelihood of depression was highest among middle-old adults and decreased to null in the oldest-old. The associations between some factors and depression were attenuated with age, suggesting a coping mechanism among oldest-old survivors.

Migration of adult male children and associated depression among community-dwelling older parents: A cross-sectional gender analysis from Longitudinal Ageing Study in India, 2017-2018

OBJECTIVES

This study empirically examines the association of migration of an adult male child (ren) on the mental health of the older parents left behind. It also examines the interaction effects of sex of older parents and male child migration on major depression to explore whether there is a gender differential in the possible association.

METHODS

The data for this study were obtained from the first wave of the Longitudinal Ageing Study in India (LASI, 2017-2018). The total sample size for the present study was 27,248 older adults aged 60 years and above (male-12,624; female-14,624). Descriptive statistics along with cross-tabulation were presented. Proportion test was used to evaluate the significance level of differences in depression by sex. Additionally, binary logistic regression analysis was used to find out the associations. Major depression with symptoms of dysphoria, was calculated using the Short-Form Composite International Diagnostic Interview (CIDI-SF).

RESULTS

About 10.5% and 9.0% of older males and females had migrant sons. It was found that there was significant gender differential in depression in older age (male: 7.5% and female: 9.7%; p < 0.001). It was further found that the prevalence of depression was found among older men (9.3% vs. 7.3%) and women (12.5% vs. 9.4%) with migrant son. Older adults with migrant son had 26% significantly higher likelihood to be depressed in reference to older adults with non-migrant son (AOR: 1.26; CI: 1.02-1.56). Further, older women with a migrant son had 76% significantly higher likelihood to be depressed in reference to older men with migrant son (AOR: 1.76; CI: 1.32-2.39).

CONCLUSIONS

This study invites policymakers' attention towards migration of adult children and its potential effects on mental health of left-behind older parents in community-settings and in women in particular. Policies should focus on spreading awareness to migrant children of older adults on maintaining frequent contacts and visits to their ageing parents.

Exploring the relationship between depression and different multimorbidity patterns among older people covered by long-term care insurance in Shanghai, China

BACKGROUND

Depression is common in patients with multimorbidity, but little is known about the relationship between depression and multimorbidity. The purpose of our research was to investigate multimorbidity patterns and their association with depression in a sample of older people covered by long-term care insurance in Shanghai, China.

METHOD

This was a population-based cross-sectional study, with 1871 participants aged ≥60 years old who are covered by Shanghai long-term care insurance. Multimorbidity was defined as the presence of two or more chronic diseases at the same time. We collected information on chronic conditions using a self-reported medical history, and we used the 30-item Geriatric Depression Scale (GDS-30) to evaluate depressive symptoms. Patterns of multimorbidity were identified with exploratory factor analysis, using oblimin rotation. Logistic regression was used to estimate the relationship between multimorbidity patterns and depressive symptoms.

RESULTS

Among the participants, the prevalence of multimorbidity was 64.7%, and the prevalence of depression was 64.6%. Hypertension, cardiovascular disease, cerebrovascular disease (CVD), and cataracts showed strong associations with depression when co-occurring with other conditions. Three patterns of multimorbidity were identified: a musculoskeletal pattern, cardiometabolic pattern, and degenerative disease pattern. Among these, the cardiometabolic (adjusted odds ratio (AOR) 1.223; 95% confidence interval (CI) 1.102, 1.357) and degenerative disease (AOR 1.185; 95% CI 1.071, 1.311) patterns were associated with a higher risk of depressive symptoms.

CONCLUSION

Two of three multimorbidity patterns were found to be associated with depression. Physical and psychological dimensions require greater attention in the care of older adults who are covered by long-term care insurance.

The effects of leisure time physical activity on depression among older women depend on intensity and frequency

BACKGROUND

Leisure time physical activity (LTPA) is beneficial for late-life depression (LLD). The main purpose of this study was to estimate the associations between LTPA parameters (intensity, duration, frequency) and LLD.

METHODS

Through the 2018 Women Health Needs Survey, data on 1,892 women aged 55-70 in Hunan, China, were studied. Depression was measured by the 9-item Patient Health Questionnaire (PHQ-9). Self-reported LTPA parameters were collected. Binary logistic regression models were used to compute odds ratios (OR) for LTPA for predicting depression. Sensitivity analyses were conducted to examine the effect of missing values.

RESULTS

Moderate LTPA volume (OR = 0.582, p = 0.027, 95% CI [0.360-0.941] for 150-299 min/week and OR = 0.392, p = 0.002, 95% CI [0.215-0.714] for ≥300 min/week) was associated with reduced depression, while vigorous LTPA could increase the risk (OR = 2.414, p = 0.029, 95% CI [1.095-5.325] for <75 min/week and OR = 3.824, p = 0.007, 95% CI [1.439-10.158] for ≥75 min/week). Frequent (6-7 days/week), moderate LTPA had a lower risk (OR = 0.570, p = 0.021, 95% CI [0.353-0.918]), while frequent (≥3 days/week), vigorous LTPA increased the risk (OR = 5.103, p = 0.001, 95% CI [1.977-13.172]). The adjusted relationship between the duration and depression was not observed. The results were supported by the sensitivity analysis based on missing value replacement.

LIMITATIONS

In this cross-sectional study, LTPA data were self-reported and no data on light LTPA were collected.

CONCLUSIONS

Moderate LTPA, associated with mental health benefits, should be recommended for older women instead of vigorous LTPA.

Association between functional limitations and depression among community-dwelling older adults in Malaysia

AIM

This study aimed to assess the relationship between functional limitations and depression among community-dwelling older adults in Malaysia.

METHODS

Data from a nation-wide community-based cross-sectional study were analyzed. This study was conducted using a two-stage stratified random sampling design. In total, 3772 older adults aged ≥60 years responded to the survey. Depression was identified using a validated Malay version of the Geriatric Depression Scale (M-GDS-14), with those scored ≥6 categorized as having depression. Functional limitations were assessed using both Barthel's Activities of Daily Living (ADL) and Lawton's Instrumental Activities of Daily Living (IADL). The relationship was determined by multivariate logistic regression, adjusted for other variables.

RESULTS

The prevalence of depression was 11.5% (95% confidence interval [CI] 9.4, 13.4). Multiple logistic regression analysis found that older adults with limitations in ADL were 2.6 times more likely of having depression (adjusted odds ratio [aOR] 2.58, 95% CI 2.01, 3.32), while those with limitations in IADL the risk of having depression was almost doubled (aOR 1.68, 95% CI: 1.32, 2.14). Other significant factors were incontinence (aOR 3.33, 95% CI: 2.33, 4.74), chronic medical illness (aOR 1.44, 95% CI: 1.15, 1.81), current smoker (aOR 4.19, 95% CI: 1.69, 10.39), poor social support (aOR 4.30, 95% CI: 2.98, 6.20), do not have partner, ethnic minorities and low individual monthly income.

CONCLUSIONS

Older adults with functional limitation in both basic ADL and complex IADL are independently at higher risk of having depression. Geriatr Gerontol Int 2020; 20: 21-25.

Built form and depression among the Chinese rural elderly: a cross-sectional study

OBJECTIVES

Few data on the association between housing structure and depression among rural elders in China are available. We examined the impact of built forms on depression.

DESIGN

This is a cross-sectional study.

SETTING

A representative sample of rural residents aged 60 years or older in China.

PARTICIPANTS

A total of 5090 older adults in 2019 in rural Suzhou, China.

OUTCOME MEASURES

Associations of built form with odds of probable and possible depression.

RESULTS

There was significant difference among elders living in varied sizes of house. Older age (vs 60-64 years: 75-79 years AdjOR, 1.737; 95% CI, 1.309 to 2.305; ≥80 years AdjOR, 2.072; 95% CI, 1.439 to 2.981), male sex (AdjOR, 0.719; 95% CI, 0.593 to 0.871), single (AdjOR, 1.303; 95% CI, 1.032 to 1.646), self-care disability (AdjOR, 4.761; 95% CI, 3.960 to 5.724), three or more chronic diseases (AdjOR, 2.200; 95% CI, 1.657 to 2.920), living alone (AdjOR, 1.443; 95% CI, 1.059 to 1.966), living in cottage (AdjOR, 1.426; 95% CI, 1.033 to 1.967), living space (vs <50 m2: 201-250 m2 AdjOR, 0.566; 95% CI, 0.359 to 0.893; >250 m2 AdjOR, 0.337; 95% CI, 0.223 to 0.511) and space per person (vs <30 m2: 30- m2 AdjOR, 0.502; 95% CI, 0.362 to 0.697; 40- m2 AdjOR, 0.473; 95% CI, 0.347 to 0.646; 50- m2 AdjOR, 0.418; 95% CI, 0.339 to 0.515) were associated with risk of depression among Chinese rural elders.

CONCLUSION

The built form was significantly and meaningfully associated with depression among Chinese rural elders. More attention should be paid to preventing mental illness among the rural elderly living in the small housing area and cottages in China.

Impacts of heart disease, depression and their combination on all-cause mortality in older people: a rural community-based cohort study in China

OBJECTIVE

To assess the impact of heart disease (HD) combined with depression on all-cause mortality in older people living in the community.

DESIGN

A population-based cohort study.

PARTICIPANTS

We examined the data of 1429 participants aged ≥60 years recruited in rural areas in Anhui province, China. Using a standard method of interview, we documented all types of HD diagnosed by doctors and used the validated Geriatric Mental Status-Automated Geriatric Examination for Computer Assisted Taxonomy algorithm to diagnose any depression for each participant at baseline in 2003. The participants were followed up for 8 years to identify vital status.

MEASUREMENTS

We sought to examine all-cause mortality rates among participants with HD only, depression only and then their combination compared with those without these diseases using multivariate adjusted Cox regression models.

RESULTS

385 deaths occurred in the cohort follow-up. Participants with baseline HD (n=91) had a significantly higher mortality (64.9 per 1000 person-years) than those without HD (42.9). In comparison to those without HD and depression, multivariate adjusted HRs for mortality in the groups of participants who had HD only, depression only and both HD and depression were 1.46 (95% CI 0.98 to 2.17), 1.79 (95% CI 1.28 to 2.48) and 2.59 (95% CI 1.12 to 5.98), respectively.

CONCLUSION

Older people with both HD and depression in China had significantly increased all-cause mortality compared with those with HD or depression only, and without either condition. Psychological interventions should be taken into consideration for older people and those with HD living in the community to improve surviving outcome.

Risk factors for depressive symptoms among older Chinese adults: A meta-analysis

BACKGROUND

The study aims to explore the risk factors for depressive symptoms among older Chinese adults.

METHODS

PubMed, PsycINFO, Cochrane Library, EMbase, Google Scholar, Chinese National Knowledge Infrastructure (CNKI), Chinese BioMedical Literature Database, and Wanfang data were searched for potentially relevant articles published before September 1^st, 2019. Stata/IC 15 was used to perform a meta-analysis and subgroup analysis to compute the pooled odds ratio.

RESULTS

The retrieve strategy yielded 11 studies that met the inclusion criteria. The total sample size was 31528 across seven districts, including Mainland China, Hong Kong, and Taiwan. Patients with depression were included in the sample size. Fourteen risk factors were extracted for at least having two or more relative studies. The combined odds ratio ranged from 0.70 to 4.75. Female, poor self-perceived financial condition, single, average and poor self-perceived health status, diabetes, adverse life events, poor social support, two or more numbers of cardiovascular diseases, and functional disability are risk factors of depressive symptoms among older Chinese adults. Fair or good social support is a protective factor.

LIMITATIONS

These findings may be somewhat limited by (i) quality of studies included, (ii) a finite number of studies met inclusion criteria.

CONCLUSIONS

Despite the methodological limitations of the studies and this meta-analysis, average or poor self-perceived health status, functional disability, poor social support, poor self-perceived financial condition, negative life events, and diabetes appear to be significant risk factors for depressive symptoms among the aged population in China. Social support can mitigate depressive symptoms.

Life negative events and depressive symptoms: the China longitudinal ageing social survey

Background

Although some studies have reported the association between life negative events and depressive disorders, very limited studies have examined the association between life negative events exposure and depressive symptoms risk among Chinese older adults.

Methods

Data were obtained from the China Longitudinal Ageing Social Survey (CLASS), which was a stratified, multi-stage, probabilistic sampling survey, conducted in 2014. General linear regression and logistic regression were used to examine the association between life negative events exposure and depressive symptoms among Chinese older adults.

Results

Life negative events showed statistical dose-response association with depressive symptoms risk after adjustment for the confounding factors (P_trend < 0.001). Under consideration of life negative events exposure, participants who lived in rural areas, without a spouse or live alone were vulnerable to depressive symptoms.

Conclusions

Life negative events played a risk role of depressive symptoms among Chinese older adults, especially among those in rural areas, females or without a spouse. Our current study is valuable for the development of special prevention depressive symptoms programs among elderly individuals, especially those who have experienced negative events.

Depressive symptoms and use of health services among older adults in Israel

Objectives

Depressive symptoms are often undetected, particularly among older adults. The purpose of this study is to provide information on the prevalence, characteristics, and patterns of depressive symptoms among older adults residing in the community in Israel, and their health-care utilization.

Methods

A cross-sectional survey was conducted among a random sample of 2502 members of one HMO in Israel, aged 65+. They were interviewed by telephone with the GDS-15 scale, which serves as the gold standard for depressive symptoms. Data from the computerized medical records of the HMO were added to the interview file, including the diagnosis of depression, purchase of antidepressant medication and use of services.

Results

The average age of respondents was 73; 54% were women. They tended to be older, living alone, suffering from falls and from sleep disorders, and to have poor subjective health status. 24% scored 6+ on the GDS scale. A significant association was found between a GDS score of 6+ and increased hospitalizations, visits to the emergency room and/or to family physicians and specialists.

Conclusion

We found a high prevalence of depression. Its negative effects on the individual and increased costs to the health system, supports the screening and treatment of the disease in the older population. This problem should be a national priority, with screening and treatment becoming part of the national quality of care indicators which would then be implemented by the HMOs as part of an integrated disease management program for the elderly.

Associations Between Somatic Multimorbidity Patterns and Depression in a Longitudinal Cohort of Middle-Aged and Older Chinese

OBJECTIVES

Depressive symptoms are commonly seen among patients with multiple chronic somatic conditions, or somatic multimorbidity (SMM); however, little is known about the relationships between depressive symptoms and different SMM combinations. Our study aimed to delineate the patterns of SMM and their longitudinal associations with depressive symptoms among a nationally representative sample of middle-aged and older Chinese adults.

DESIGN

We employed a longitudinal design.

SETTING AND PARTICIPANTS

Older adults (N = 10,084) aged ≥45 years from the China Health and Retirement Longitudinal Study 2011-2015 participated (mean age = 57.7 years at baseline; 53.3% men).

METHODS

Sixteen chronic somatic conditions were ascertained at baseline via questionnaires. Depression was assessed with the Center for Epidemiological Studies Depression Scale at baseline and during follow-up. Patterns of SMM were identified via exploratory factor analyses. Generalized estimating equations were used to evaluate the longitudinal associations between patterns of SMM and the presence of depressive symptoms at follow-up.

RESULTS

Compared with participants with no somatic condition, those with 1, 2, and 3 or more somatic conditions had a 21%, 66%, and 111% greater risk, respectively, for the presence of depressive symptoms. Increased factor scores for 4 patterns identified, cardio-metabolic pattern [adjusted odds ratio (AOR) 1.12, 95% confidence interval (CI) 1.06, 1.20], respiratory pattern (AOR 1.25, 95% CI 1.17, 1.33), arthritic-digestive-visual pattern (AOR 1.29, 95% CI 1.22, 1.37), and hepatic-renal-skeletal pattern (AOR 1.09, 95% CI 1.02, 1.16), were all associated with a higher risk of having depressive symptoms.

CONCLUSIONS AND IMPLICATIONS

All SMM patterns were independently associated with depression among middle-aged and older Chinese adults, with greater odds for people with comorbid arthritic-digestive-visual conditions and respiratory conditions. Clinical practitioners should treat the middle-aged and older population under a multiple-condition framework combining SMM and mental disorders.

Association Between Multimorbidity and Depressive Symptom Among Community-Dwelling Elders in Eastern China

Purpose

This study aimed to investigate the prevalence of depressive symptoms and the association between multimorbidity and depressive symptoms among the elderly in eastern China.

Patients and methods

A multicenter cross-sectional study was conducted in four cities (Jianggan, Yiwu and Anji in Zhejiang Province and Taixing in Jiangsu Province) in eastern China. We collected the information on 27 chronic conditions through the self-reported medical history and used the Geriatric Depression Scale (GDS) short form to evaluate depressive symptoms. Multivariate Logistic regression was used to evaluate the relationship between multimorbidity and depressive symptoms.

Results

Five thousand two hundred and ninety-six participants were included into the current study, among which 2687 (50.74%) were female, with the mean ± SD age 72.0 ± 8.1 years old. The overall prevalence of depressive symptoms in eastern China was 23.5%. And the percentage of multimorbidity in depressed participants was higher compared with non-depressed participants (50.8% vs 38.8%, P<0.001). The univariate model and adjusted model suggested that participants with multiple chronic diseases were more likely to have a depressive symptom (adjusted OR=1.42; 95% CIs 1.19–1.70).

Conclusion

Depressive symptom was significantly associated with multimorbidity among the community-dwelling elderly population in eastern China.

Correlation Between Depressive Symptoms And Quality Of Life, And Associated Factors For Depressive Symptoms Among Rural Elderly In Anhui, China

Purpose

We aimed to assess the current status of depressive symptoms and quality of life (QoL) among rural elderly in central China (Anhui Province) and explore their correlation and associated factors for depressive symptoms.

Methods

A multi-stage random sampling method was used to obtain 3349 participants (aged ≥60): 1206 poor and 2143 non-poor. The 30-item Geriatric Depression Scale (GDS-30) and five-dimensional European quality of health scale (EQ-5D) were employed to evaluate depressive symptoms and QoL, respectively.

Results

The prevalence of depressive symptoms was 52.9%, and that in the poor group (62.3%) was significantly higher than the non-poor group (47.6%). The GDS-30 score was 12.40 ± 7.089, and the poor group scored significantly higher (14.045 ± 6.929) than the non-poor group (11.472 ± 7.011). The EQ-5D score was 0.713 ± 0.186, and the poor group (0.668 ± 0.192) scored significantly lower than the non-poor group (0.738 ± 0.178). There was a significant negative correlation between depressive symptoms and QoL (r = −0.400, P-value <0.05). The following factors were associated with depressive symptoms: poverty, low EQ-5D score, female gender, older age, illiteracy, unemployed, chronic diseases, and hospitalization in previous year.

Conclusion

Rural elderly in central China have a high prevalence of depressive symptoms and low QoL. Poverty was associated with a higher prevalence of depressive symptoms and lower QoL.

Socio-demographic characteristics and co-occurrence of depressive symptoms with chronic diseases among older adults in China: the China longitudinal ageing social survey

BACKGROUND

The aim of the current study is to assess the cross-sectional association of chronic non-communicable diseases (hypertension, diabetes mellitus, arthritis, and cerebrovascular) with depressive symptoms among older adults in China.

METHODS

Data was obtained from the China Longitudinal Ageing Social Survey (CLASS) conducted in 2014. A total of 7505 participants were included. Depressive symptoms status was assessed by 9-item Center for Epidemiological Studies Depression Scale (CES-D) Associations between depressive symptoms and chronic diseases, adjusting for so, demographics and chronic diseases risk factors were assessed by using logistic regression model.

RESULTS

We found negative associations between depressive symptoms and several socioeconomic factors, including education attainment and economic level. Widowed/divorced/ unmarried individuals are more likely to suffer from depressive symptoms. Hypertension (Odds ratio:1.29 [95%CI:1.16, 1.42]), diabetes (1.41 [95%CI:1.19,1.67]), arthritis (1.72 [1.52, 1.96]), and cerebrovascular disease (1.69 [1.41, 2.02]) were found to be associated with depressive symptoms.

CONCLUSIONS

Most depressive symptoms cases were found to be significantly associated with chronic diseases. Our findings have provided evidence for understanding co-morbid depressive symptoms with chronic diseases, which could help clinicians to evaluate, diagnose and manage depression promptly.

Moderating effect of social support on depression and health promoting lifestyle for Chinese empty nesters: A cross-sectional study

BACKGROUND

Health promoting lifestyle (HPL) may be a facilitator for empty nesters' active aging against depression. Social support (SS) may improve their HPL. This study aimed to examine moderating effect of SS and its three sources of SS on relationship between depression and HPL among empty nesters. The compensating role of socioeconomic status (SES) for lack of SS was examined, too.

METHODS

A cross-sectional survey of empty nesters (n = 1593) was conducted in six districts of Taiyuan, China, using a stratified random cluster sampling method. Hierarchical multiple linear regression analyses were performed to assess moderation models by SS and its three sources.

RESULTS

The findings indicated that low depression (p < 0.001) and sufficient perceived SS (p < 0.001) could directly predict better HPL among empty nesters. The effect of SS on HPL declined with the raise of educational level (p < 0.001). Family support (β = 0.083, p < 0.001), friends support (β = 0.085, p < 0.001) and others support (β = 0.098, p < 0.001) expressed significant negative buffer effects on depression and HPL individually.

LIMITATIONS

There was a cross-sectional study that limited the moderating effect of SS on depression and HPL just for empty nesters in Taiyuan, China. The results cannot explain the causal relationships among the study variables.

CONCLUSIONS

SS might be a protective factor of empty nesters' health in China. Three sources of SS all showed moderating effect on the relationship between depression and HPL among empty nesters, and should be integrated to achieve maximum utility. Friends support/ others support could play complement role for lack of family support. SES expressed partial compensatory for lack of SS.

Melancholy or mahjong? Diversity, frequency, type, and rural-urban divide of social participation and depression in middle- and old-aged Chinese: A fixed-effects analysis

The potential benefit of social participation (SP) to one's mental health has been widely acknowledged. Nevertheless, the specific type and amount of SP that is associated with improved depressive symptoms in middle- and old-aged Chinese awaits further investigation. This study aimed to understand the patterns of depression and SP by comparing urban vs rural China, and according to which, measure the associations between changes in SP and that in depressive symptoms. A total of 10,988 community residents aged 45 years and above were selected from wave 1 (2011), wave 2 (2013), and wave 4 (2015) of the China Health and Retirement Longitudinal Study (CHARLS), a nationally representative survey. The fixed-effects analysis was used to explore the association between the changes in diversity, frequency, and type of SP and the changes in depressive symptoms. The results indicated that rural respondents suffered from a significantly higher risk of depression and took less SP than their urban counterparts. Transitioning from no SP to 1 or more types of SP or to a once a week or higher frequency was associated with a decline in depressive symptoms. For urban respondents, playing mah-jong or cards and joining sports or social clubs predicted a decline in depressive symptoms. For rural residents, interacting with friends regularly was associated with fewer depressive symptoms. In conclusion, more diverse and higher frequency of SP was associated with better mental health, while the social significance of SP varied across different types of SP and between rural and urban areas.

Intensity, frequency, duration, and volume of physical activity and its association with risk of depression in middle- and older-aged Chinese: Evidence from the China Health and Retirement Longitudinal Study, 2015

Background

The general benefit of physical activity (PA) to one’s mental health has been widely acknowledged. Nevertheless, the specific type and amount of PA that associates with lower risk of depression in China awaits further investigation. The present study was conducted on middle- and older-aged Chinese population with two objectives: 1) to understand the patterns of PA; 2) to measure the associations between depression and PA at different levels from various aspects.

Methods

Using data from the China Health and Retirement Longitudinal Study (CHARLS, 2015), we selected 9118 community residents aged 45 years and older. Depressive symptoms were measured by 10-item Center for Epidemiologic Studies (CES-D 10). Multivariate logistic regression model was performed to examine the association between risk of depression and PA from four aspects including intensity, frequency, duration, and volume.

Results

Spending 1–2 days/week (OR = 0.58, 95% CI: 0.36, 0.91), less than 30 minutes each time (OR = 0.66, 95% CI: 0.42, 1.03) or 150–299 min/week (OR = 0.49, 95% CI: 0.28, 0.87) on Moderate Physical Activity (MPA) was associated with lower odds of depression in women. Spending 3–5 days/week (OR = 1.98, 95% CI: 1.29, 3.05) or 6–7 days/week (OR = 1.50, 95% CI: 1.07, 2.11), 4 hours and longer each time (OR = 1.65, 95% CI: 1.18, 2.32), 300 min/week or longer (OR = 1.65, 95% CI: 1.22, 2.24) on Vigorous Physical Activity (VPA) in total, or 2250 Metabolic Equivalent of Task (OR = 1.73, 95% CI: 1.26, 2.38) on Moderate-to-Vigorous PA was associated with higher risk of depression in men.

Conclusions

The association between depression and PA depended largely on intensity and gender. Lower frequency, shorter duration, and moderate amount of MPA was associated with lower risk of depression in women. Risk of depression was higher in men who spent higher frequency, longer duration, and overlong time on VPA.

A Cross Sectional Examination of the Relation Between Depression and Frequency of Leisure Time Physical Exercise among the Elderly in Jinan, China

Depression has become a major global public health problem. Many studies have shown the positive effects of physical exercise on depression. However, few studies have examined the relationship between frequency of leisure time physical exercise and depression without considering the time and intensity of exercise among middle-aged and elderly people of urban communities in northern China. We conducted a cross-sectional survey that included 1604 participants among urban residents aged 50 years or older in China to evaluate how the frequency of physical exercise was related to depression. Our study showed that the prevalence of depression in the urban community of Jinan is 16.52%. For physical exercise, the odds ratios (ORs) and 95% confidence intervals (CIs) for 1~2 times per week, 3~4 times per week and ≥5 times per week were 1.137 (0.661, 1.953), 0.516 (0.304, 0.875) and 0.548 (0.392, 0.768) respectively, with adjustment for age, gender, marital status, BMI, hypertension, previously diagnosed type 2 diabetes, triglyceride, total cholesterol, soy food intake, milk food intake, vegetable and fruit intake and meat intake. We concluded that physically exercising three times a week is associated with a low prevalence of depression.

Health-promoting behaviors and quality of life in older adults with hypertension as compared to a community control group

Hypertension (HTN) related to health-promoting behaviors (HPB) and quality of life (QOL) in older Chinese has not been clearly identified. We sought to compare the HPB and QOL of elderly adults (aged ≥60) living with HTN in China to a community normotensive control group. Using multistage stratified cluster sampling, a sample of 543 elderly people with HTN and 550 with normotension were randomly selected and asked to complete questionnaires. The Chinese version of the Health Promoting Lifestyle Profile (HPLP-IICR) and The World Health Organization Quality of life-BREF instrument (WHOQOL-BREF) were used to evaluate the HPB and QOL of elderly adults. As compared to the normotensive elderly, the hypertensive elderly showed significantly lower scores in their spiritual growth and health management (both P < 0.05), but not in the other three domains. Also, the participants with HTN showed significantly lower scores in the QOL overall and physical health (both P < 0.05), but not in other factors, as compared to the participants without HTN. Each HPLP-IICR domain score among the elderly with or without HTN were significantly correlated with their QOL scores (all P < 0.01). It is suggested that more attention should be paid to improving the spiritual growth and health management of HBP, and thus the overall quality of life among hypertensive patients.

Intergenerational relationships and the trajectory of depressive symptoms among older Chinese adults in rural migrant families

OBJECTIVES

This study examined the trajectory patterns of depressive symptoms of older rural Chinese adults in migrant families and the role of intergenerational relationships in predicting trajectory class memberships.

METHOD

Data were derived from the 2001, 2003, 2006, and 2009 waves of a longitudinal survey titled The Well-being of Older People in Anhui Province. The sample featured 486 respondents who had at least one migrant adult children at all four waves. Growth mixture modeling was used to investigate the trajectory classifications of depressive symptoms from 2001 to 2009 and antecedents in differentiating among class memberships.

RESULTS

The findings suggested a two-class model to interpret depressive symptom trajectory patterns: persistently high symptoms and low but increasing symptoms. Older adults who had better intergenerational relationships at baseline were more likely to have low but increasing depressive symptoms after controlling for other covariates.

DISCUSSION

The findings suggest that intergenerational relationships have long-term impacts on depressive symptom trajectory classes. Policy and intervention implications are discussed.

Depressive symptoms and their association with social determinants and chronic diseases in middle-aged and elderly Chinese people

Depression is one of the most prevalent mental disorders worldwide. Little information is available regarding association of depressive symptoms (DS) with cancer and chronic diseases among middle-aged and elderly Chinese in a population-based setting. In this study we evaluated the prevalence and examined correlates of DS in two population-based cohort studies. Included in the analyses were 103,595 people with a mean age of 61.8 years at the DS assessment. The prevalence of DS was 2.4% in men and 5.6% in women. We found elderly participants, those with lower BMI, or chronic diseases were more likely to experience DS. Having a history of stroke (odds ratio (OR) = 2.2 in men and 1.8 in women), cancer (OR = 3.3 in men and 1.9 in women), or Parkinson's disease (OR = 3.1 in men and 2.7 in women) was associated with high DS. In women, high income and high education levels were inversely related to DS. Being a single woman, long-term or heavy female smoker was associated with high prevalence of DS. High BMI was correlated with low prevalence of depression in men. Our data suggests a low prevalence of DS among middle-aged and elderly people in Shanghai, China. Age, education, income, marital status, smoking, BMI, and certain health conditions were associated with DS.

Prevalence of Mental Disorders among Older Chinese People in Tianjin City

OBJECTIVE

Population aging is accelerating across the world, and older people have a higher risk of mental disorders. Most studies focus on one mental disorder, and only report the current prevalence. Besides, these studies use screening scales for symptoms of mental disorders, which may induce biased results. In this study, we used data for diagnoses based on SCID that had been administered by trained psychiatrists to explore the 1-month and lifetime prevalence of mental disorders among a Chinese aged cohort.

METHODS

Data for this study was derived from the Tianjin Mental Health Survey. Participants were first screened using a General Health Questionnaire and 9 additional items on other risk factors for mental disorders, and then diagnosed with the Chinese version of Structured Clinical Interview for Diagnostic and Statistical Manual (DSM-IV) Axis I disorders. A total of 3,325 people aged 60 and above had valid information, and 1,486 completed the SCID interview.

RESULTS

The weighted 1-month prevalence of mental disorders was 14.27%, whereas the lifetime prevalence of mental disorders was 24.20%. Most of these participants were female, older, currently not married, of lower education level, and with poor family economic status. Organic mental disorders had the highest 1-month prevalence (4.45%), whereas mood disorder was highest for the lifetime prevalence (9.75%).

CONCLUSION

Older Chinese people had a high prevalence of mental disorders. Further research and health services innovations are needed to address the high prevalence in these subgroups among older people.

Multimorbidity and depression: A systematic review and meta-analysis

BACKGROUND

Multimorbidity, the presence of two or more chronic conditions, is increasingly common and complicates the assessment and management of depression. The aim was to investigate the relationship between multimorbidity and depression.

METHOD

A systematic literature search was conducted using the databases; PsychINFO, Medline, Embase, CINAHL and Cochrane Central. Results were meta-analysed to determine risk for a depressive disorder or depressive symptoms in people with multimorbidity.

RESULTS

Forty articles were identified as eligible (n = 381527). The risk for depressive disorder was twice as great for people with multimorbidity compared to those without multimorbidity [RR: 2.13 (95% CI 1.62-2.80) p<0.001] and three times greater for people with multimorbidity compared to those without any chronic physical condition [RR: 2.97 (95% CI 2.06-4.27) p<0.001]. There was a 45% greater odds of having a depressive disorder with each additional chronic condition compared to the odds of having a depressive disorder with no chronic physical condition [OR: 1.45 (95% CI 1.28-1.64) p<0.001]. A significant but weak association was found between the number of chronic conditions and depressive symptoms [r = 0.26 (95% CI 0.18-0.33) p <0.001].

LIMITATIONS

Although valid measures of depression were used in these studies, the majority assessed the presence or absence of multimorbidity by self-report measures.

CONCLUSIONS

Depression is two to three times more likely in people with multimorbidity compared to people without multimorbidity or those who have no chronic physical condition. Greater knowledge of this risk supports identification and management of depression.

A randomized, double-blind clinical study to determine the effect of ANKASCIN 568 plus on blood glucose regulation

Diabetes is the fourth major cause of death in Taiwan. High blood glucose can lead to macrovascular diseases,small vessel diseases (retinopathy, kidney disease), and neuropathy. This study aimed to investigate whether Monascus-fermented products (ANKASCIN 568 plus) can regulate blood glucose and blood lipids. This study enrolled 39 patients with a fasting blood glucose level between 100 mg/dL and 180 mg/dL, and a glycated hemoglobin (HbA1c) level of <9%. All patients were randomly divided into placebo (n = 20) and experimental (n = 19) groups. Each patient received two placebo capsules (maltodextrin) or ANKASCIN 568 plus capsules daily for 12 weeks. The patients were screened during follow-up 4 weeks after the administration of sample or placebo had been discontinued. Blood and urine samples were collected at the initial, 6^th week, 12^th week, and 16^th week. The anthropometric indicators of blood pressure, fasting plasma glucose level, postprandial plasma glucose level, insulin level, insulin resistance, blood lipid changes, and liver, kidney, and thyroid function indices were measured. After 6weeks, changes in fasting blood glucose, low-density lipoprotein cholesterol (LDL-C),and total cholesterol (TC) levels showed thatANKASCIN568 plus had amore favorable effect than the placebo. Compared to baseline, a statistically significant decrease of 8.5%, 10.3%, and 7.5% was observed in fasting blood glucose, LDL-C and, TC levels, respectively (p < 0.05 for all pairs). Therefore, ANKASCIN568 plus produced by Monascus purpureus NTU 568 fermentation may be a potentially useful agent for the regulation of blood glucose and blood lipids and for treatment of coronary artery diseases.

Factors associated with and prevalence of depressive features amongst older adults in an urban city in eastern China

Background

Mental health problems have become serious for older Chinese adults who have lived through the process of urbanisation. This current research aimed to determine the prevalence of and associated factors for depressive features in a community-based sample of older adults in China.

Methods

A community-based survey of 4077 adults aged 60 or older was conducted in Suzhou, China. Information including demographic characteristics, health behaviours, social support, disease histories and physical function was collected using a pre-designed questionnaire. Depressive features were assessed using the self-rating depression scale. Multivariate logistic regression analysis was performed to identify associated factors for depression.

Results

The overall prevalence of depressive features in the surveyed population was 47.4% (45.9% in men and 48.5% in women). In a multiple logistic regression analysis, the significant variables of depressive features were no fixed occupation (odds ratio [OR] = 0.28; 95% confidence interval [CI]: 0.21–0.37), doing non-technical and service work (OR = 0.23; 95% CI: 0.19–0.28) or being a manager and technical personnel (OR = 0.25; 95% CI: 0.19–0.32), physical activities (OR = 0.71; 95% CI: 0.61–0.82), never taking dietary supplements (OR = 0.73; 95% CI: 0.58–0.91), not having hobbies (OR = 1.34; 95% CI: 1.15–1.56), never interacting with neighbours (OR = 1.79; 95% CI: 1.28–2.50), cold relationship with a spouse (OR = 3.34; 95% CI: 1.18–9.45) and limited activities of daily living (OR = 2.27; 95% CI: 1.91–2.69).

Conclusion

There is an urgent need for public policy interventions to address depression in elderly people located in Suzhou in China.

Health, Social, and Economic Variables Associated with Depression Among Older People in Low and Middle Income Countries: World Health Organization Study on Global AGEing and Adult Health

OBJECTIVE

Although depression among older people is an important public health problem worldwide, systematic studies evaluating its prevalence and determinants in low and middle income countries (LMICs) are sparse. The biopsychosocial model of depression and prevailing socioeconomic hardships for older people in LMICs have provided the impetus to determine the prevalence of geriatric depression; to study its associations with health, social, and economic variables; and to investigate socioeconomic inequalities in depression prevalence in LMICs.

METHODS

The authors accessed the World Health Organization Study on Global AGEing and Adult Health Wave 1 data that studied nationally representative samples from six large LMICs (N = 14,877). A computerized algorithm derived depression diagnoses. The authors assessed hypothesized associations using survey multivariate logistic regression models for each LMIC and pooled their risk estimates by meta-analyses and investigated related socioeconomic inequalities using concentration indices.

RESULTS

Cross-national prevalence of geriatric depression was 4.7% (95% CI: 1.9%-11.9%). Female gender, illiteracy, poverty, indebtedness, past informal-sector occupation, bereavement, angina, and stroke had significant positive associations, whereas pension support and health insurance showed significant negative associations with geriatric depression. Pro-poor inequality of geriatric depression were documented in five LMICs.

CONCLUSIONS

Socioeconomic factors and related inequalities may predispose, precipitate, or perpetuate depression amongolder people in LMICs. Relative absence of health safety net places socioeconomically disadvantaged older people in LMICs at risk. The need for population-based public health interventions and policies to prevent and to manage geriatric depression effectively in LMICs cannot be overemphasized.

Sintomas depressivos em idosos: estudo transversal de base populacional

Resumo Foi realizado um estudo transversal de base populacional na cidade de Pelotas, Rio Grande do Sul, em 2014, com o objetivo de medir a prevalência e identificar os fatores associados aos sintomas depressivos em idosos. A amostragem foi realizada por conglomerados em dois estágios. Todos os idosos (≥ 60 anos) residentes nos domicílios selecionados foram convidados a participar. A ocorrência dos sintomas depressivos foi medida utilizando-se a GDS-10 (Geriatric Depression Scale) com o ponto de corte ≥ 5. Foram obtidas informações de 1.451 idosos. A prevalência dos sintomas depressivos foi de 15,2% (IC95% 13,2-17,2). Após análise multivariável, a ocorrência de sintomas depressivos foi maior entre as mulheres, os idosos de pior situação econômica, aqueles que não trabalhavam, os fisicamente inativos, aqueles com pior autoavaliação de saúde e naqueles com incapacidade funcional. Maior atenção deve ser dada à identificação de sintomas depressivos em idosos e seus fatores associados para fundamentar políticas e planejamentos de intervenções para tratamento e manejo desta doença em nível coletivo.

Prevalence of depression and its associated factors among Chinese elderly people: A comparison study between community-based population and hospitalized population

Depression is common among elderly people, but people from various study settings were at different levels of risk for depression. However, most of the existing studies were conducted among community population, and little was known about depression among institutionalized population. In this study, using a national sample, we aimed to compare the prevalence rate of depression and its associated factors between community-dwelling elderly people (CDEP) and elderly medical inpatients (EMI). Data for this study was derived from a national survey of the 2011 Comprehensive Assessment of Elderly Health. The Geriatric Depression Scale was used to assess depression. The results indicated that the prevalence rate of depression among EMI was significantly higher than that in CDEP (18.1% vs 11.6%, P<0.001). Physical health status was found to be the most important factor associated with depression among both groups. This study revealed a high prevalence rate of depression among Chinese elderly people, especially for those medically institutionalized. It's essential to pay more efforts on the training of general practitioners for early screening and identification of depression on the admission of elderly patients and during their hospitalization, and case management of the elderly medical inpatients on assessment and treatment for depression may be beneficial.

A Community-Based Study of Quality of Life and Depression among Older Adults

The goal of the study was to assess the quality of life (QOL) and depression and provide further insights into the relationship between QOL and depression among community-dwelling elderly Chinese people. Baseline data were collected from 1168 older adults (aged ≥ 60) in a large, prospective cohort study on measurement and evaluation of health-promoting and health-protecting behaviors intervention on chronic disease in different community-dwelling age groups. QOL was assessed using the 26-item, World Health Organization Quality of Life, brief version (WHOQOL-BREF) and depression was assessed using the 30-item Geriatric Depression Scale (GDS). The mean WHOQOL-BREF score for all dimensions was approximately 60, with the highest mean value (61.92) observed for social relationships, followed by environment, physical health, and psychological health domains. In this cohort, 26.1% of elderly urban adults met GDS criteria for depression. There were negative correlations between physical health (Odds Ratio (OR) = 0.928, 95% Confidence Interval (CI): 0.910–0.946), psychological health (OR = 0.906, 95% CI: 0.879–0.934), environment (OR = 0.966, 95% CI: 0.944–0.989) and depression among elderly people. Those with depression were older, less educated, had a lower monthly income, and were more likely to report insomnia. All WHOQOL-BREF domains, with the exception of the social domain were negatively correlated with depression.

Leisure, functional disability and depression among older Chinese living in residential care homes

OBJECTIVES

Previous research has rarely examined the intervening and buffering effects of leisure on the relationship between age-related stress and health among institutionalized elders, especially in the Chinese context. This study thus examines the extent to which participation in leisure activities mediates and moderates the impact of functional disability on depression among older adults living in residential care homes in China.

METHOD

A total of 1429 participants (858 men) aged over 60 living in residential care homes, of which 46.1% experienced depression using a cut-off score ≥ 5 on the 15-item Geriatric Depression Scale, were selected from a national survey across China by using the probability proportional to size sampling method.

RESULTS

The findings showed that depression was positively predicted by functional disability and negatively predicted by participation in leisure activities. The results of the mediation analysis showed that participation in leisure activities partially mediated the relationship between functional disability and depression. Functional disability predicted depression both directly and indirectly through its negative influence on participation in leisure activities. Participation in leisure activities also significantly buffered the relationship between functional disability and depression such that the impact of functional disability was weaker for those who participated in leisure activities more frequently.

CONCLUSION

These results provide support for the mediating and moderating roles of leisure in the stress-health relationship among institutionalized elders. To enhance residents' psychological health, residential care homes are recommended to organize more leisure activities.
