Social factors relating to depression among older people in Japan: analysis of longitudinal panel data from the AGES project

Incidence of depression among community-dwelling older adults: A systematic review

We aimed to synthesise information related to the incidence of depression and depressive symptoms (DDS) in a community-dwelling older adult population at a global level. In this systematic review, we included articles with a cohort study design that evaluated the incidence of depression or depressive symptoms in older adults aged 60 years or more in a community-dwelling environment. Six databases were used: Web of Science, PubMed, Scopus, LILACS, SciELO, and Cochrane, and the entire selection process was independently performed by peers. We divided the included articles into subgroups according to the DDS assessment instrument: (i) Geriatric Depression Scale; (ii) Center for Epidemiologic Studies Depression Scale; (iii) miscellaneous scales; and (iv) diagnostic interviews. Each cumulative incidence value obtained per item was adjusted for a 1-year follow-up period, which generated an annual cumulative incidence (AcI). From 46 articles, 42 used scales to evaluate the depressive variable, with an AcI estimate of around 4.5%. The articles that assessed depression categorically observed a variation in AcI between 0.2% and 7.0%. Among all the materials included, the group that used the Geriatric Depression Scale observed the lowest and the highest AcI, 1.3% and 26.6% respectively. Most of the productions were from countries in the Asian continent (52.2%), followed by Europe (30.4%), the Americas (13%), and Oceania (4.4%). Despite the variation of AcI, we found a frequent occurrence of DDS in older adults in the community-dwelling environment, which highlights the need for preventive actions and better-targeted early care, especially in terms of primary health care.

Analysis of depression status and influencing factors in middle-aged and elderly patients with chronic diseases

Objectives

To explore prevalence of depression and its influencing factors in middle-aged and elderly patients with chronic diseases.

Method

Data were extracted from the 2018 China Health and Retirement Tracking Survey (CHARLS) for 6,704 middle-aged and elderly patients ≥45 years with chronic diseases. The influencing variables were selected based on LASSO-logistic regression model, and a nomogram was further drawn to visualize regression results.

Results

Comorbidity between chronic diseases and depression symptoms were detected in 3058 individuals (45.6%). Female, rural, lower education, poor, insomnia, multiple chronic disease, and functional impairment were associated with a higher proportion of depression. Meanwhile, family interaction, intergenerational financial support, social activity intensity, and satisfaction with life can protect against depression.

Conclusion

Depressive symptoms are common in Chinese older adults with chronic diseases. They need regular assessment and intervention, especially those with multiple diseases, female, rural, alone, impaired, poor sleep, or poor economy. These high-risk elders also need family, medical, and social support and care.

Socioeconomic status and incident depressive symptoms among older adults: A 3-year longitudinal study from the Japan Gerontological Evaluation Study

OBJECTIVES

The association between socioeconomic status (SES) and the onset of depressive symptoms has attracted considerable attention. However, few studies have simultaneously examined the association of multiple SES indicators, including "assets," with the onset of depressive symptoms. Therefore, this study examined the association of four SES indicators in old age ('years of education' 'equivalent income,' 'equivalent assets,' and 'the longest-held job') with new-onset depressive symptoms in a large Japanese dataset.

METHODS

This longitudinal study used panel data of cognitively and physically independent older adults from the Japan Gerontological Evaluation Study (JAGES) conducted in 2013 and 2016. Multivariate logistic regression analysis was conducted to examine the association of each SES indicator with new-onset depressive symptoms, and odds ratios and 95% confidence intervals (CIs) were calculated.

RESULTS

We analyzed the data of 40,257 older adults, with a mean age (± standard deviation) of 72.9 (±5.5) years. In the follow-up survey, 4292 older adults had new-onset depression symptoms (10.7%). 39.3% had 10-12 years of education. 36.9% had an equivalent income of up to JPY 1.99 million. 24.4% had equivalent assets of JPY 4-17.99 million. Most had a clerical job for the long time. Furthermore, fewer years of education (males: OR = 1.42, 95% CI = 1.22-1.64, p-value <0.001/females: 1.26, [1.09-1.47], p = 0.002), lower income (males: 1.64, [1.34-2.01], p < 0.001/females: 1.82, [1.49-2.22], p < 0.001), and fewer assets (males: 1.40, [1.16-1.68], p < 0.001/females: 1.21, [1.02-1.42], p = 0.025) resulted in higher odds of having new-onset depressive symptoms, even when other SES indicators were entered simultaneously.

CONCLUSIONS

All four SES indicators have an independent association with the development of new-onset depressive symptoms among older adults, reflecting different aspects of SES. The association between the "longest-held job" and new-onset depressive symptoms can be largely explained by other SES indicators. A multifaceted and lifetime approach is required to prevent the onset of depressive symptoms in old age.

Depression in Older Adults: Do Current DSM Diagnostic Criteria Really Fit?

OBJECTIVES

The great heterogeneity in symptoms and clinical signs of depression in older adults makes the current diagnostic criteria difficult to apply. This scoping review aims to provide an update on the relevance of each of the diagnostic criteria as defined in the DSM-5.

METHODS

In order to limit the risk of bias inherent in the study selection process, a priori inclusion and exclusion criteria were defined. Articles meeting these criteria were identified using a combination of search terms entered into PubMed, PsycINFO, PsycARTICLES and SocINDEX.

RESULTS

Of the 894 articles identified, 33 articles were selected. This review highlights a different presentation of depression in older adults. Beyond the first two DSM core criteria, some symptoms are more common in older adults: appetite change, sleep disturbance, psychomotor slowing, difficulty concentrating, indecisiveness, and fatigue.

CONCLUSIONS

This review provides an updated description of the clinical expression of depressive symptoms in the older population while highlighting current pending issues.

CLINICAL IMPLICATIONS

Somatic symptoms should be systematically considered in order to improve the diagnosis of depression in older adults, even if, in some cases, they may reflect symptoms of age-related illnesses.

The trajectory of non-depressed suicidal ideation in community-dwelling older people in a rural area in Japan: a prospective longitudinal study with a 3-year follow-up

BACKGROUND

Suicidal ideation is closely related to severe suicidal behaviour and is an important predictor of suicide attempt and completion, including in older people. Older people tend to have many opportunities to be conscious of death, and may have vague suicidal ideation because of various loss experiences, even if they are not depressed. We hypothesised that suicidal ideation among older people might be a risk factor for later transition to depression. The present study aimed to clarify risk factors that predict the incidence of depression in older people 3 years post-baseline in a rural area of Japan, and to examine the subsequent course of depression among non-depressed older people with suicidal ideation.

METHODS

In 2015 and 2018, survey questionnaires were mailed to residents aged 65 years and over living in a rural area in Japan. Participants were divided into a depression group and a non-depression group using 15-item Geriatric Depression Scale scores 3 years post-baseline. Logistic regression analysis was used to identify predictive factors of late-life depression 3 years post-baseline.

RESULTS

We received 597 valid responses, with a 3-year follow-up rate of 78.8%. Regarding suicidal ideation, 6.7% of non-depressed older people exhibited suicidal ideation at baseline. Of these, 9.8% exhibited depression after 3 years post-baseline. Logistic regression analysis indicated that development of late-life depression is significantly associated with suicidal ideation, being female, and poor health-related quality of life (HRQOL).

CONCLUSIONS

The results revealed that suicidal ideation, being female, and poor HRQOL were predictive factors of the development of late-life depression 3 years post-baseline in a rural area of Japan. These findings provide novel information regarding the transition to depression among community-dwelling older people who are not depressed but have suicidal ideation. Whereas suicidal ideation is considered to be a symptom of depression, the current results suggest that suicidal ideation may precede depression in some older people.

Video call and depression among older adults during the COVID-19 pandemic in Japan: The JAGES one-year longitudinal study

Evidence of video call on preventing late-life depression during the COVID-19 pandemic is limited. We examined the associations of social contact (in-person, voice call, and video call) with incidence of depressive symptoms and evaluated whether specific factors (particularly, age and change in the frequency of in-person contact) affect these associations. We used longitudinal data from the 2019 and 2020 waves of the Japan Gerontological Evaluation Study, including 10,523 participants aged ≥65 years in 10 municipalities. Depressive symptoms were measured by the 15-item Geriatric Depression Scale (GDS-15) score ≥5 in main analysis, and GDS-15 score ≥4, 10, or continuous variable in sensitivity analyses. Social contact represented frequency changes before and during the pandemic: non-contact (reference), decreased-contact, maintained-contact, and increased-contact. We employed modified Poisson regression analysis. Compared to non-contact of video call, the association of increased-contact of video call with depressive symptoms was insignificant in main analysis (GDS-15 ≥ 5: risk ratio (RR) = 0.89, 95% confidence interval (CI): 0.79-1.01), whereas significant in sensitivity analyses (GDS-15 ≥ 4: RR = 0.89, 95% CI: 0.82-0.98; GDS-15 ≥ 10: RR = 0.71, 95% CI: 0.53-0.97; GDS-15 = continuous variable: Β = -0.17, 95% CI: -0.33 to -0.002). In-person contact was significantly associated with lower incidence of depressive symptoms (non-contact: reference; maintained-contact: RR = 0.92, 95% CI: 0.85-0.99; increased-contact: RR = 0.84, 95% CI: 0.77-0.91), whereas voice call was not. Age and change in the frequency of in-person contact did not show significant effect modifications on the associations of video call with incidence of depressive symptoms after Bonferroni correction for multiple testing. In conclusion, this study suggests that the evidence supporting video call as a way to protect against depressive symptoms among older adults during the pandemic appears weak compared to the evidence for in-person contact.

Impact of migration status on incidence of depression in the middle-aged and elderly population in China: Exploring healthy migrant and salmon bias hypotheses from a mental health perspective

BACKGROUND

The healthy migrant and salmon bias hypotheses stipulate that those who are healthier are more likely to migrate (a selection effect) and unhealthy migrants have a greater tendency to return to their origin communities than healthier migrants. It remains unclear whether the hypotheses are relevant for mental health, although they have robust evidence for physical health. The current study expands the theoretical foundation underlying these hypotheses by exploring the impact of migration status on depression among the middle-aged and older population in China.

METHOD

Longitudinal data from the China Health and Retirement Longitudinal Study (CHARLS) in 2011, 2013, 2015 and 2018 were used. Participants were divided into three groups, non-migrants, permanent migrants, and return-migrants according to their migration status. The Chinese version of 10-item Center for Epidemiologic Studies Depression Scale was used to assess clinically relevant depressive symptoms. Incidence were estimated by each migration status and compared across strata using log-rank tests. Cox regression models were fit to assess the relationship between migration status and depression incidence.

RESULTS

A total of 9264 middle-aged and elderly participants were included, of whom 7047 (76.1 %) were non-migrants, 1065 (11.5 %) were permanent migrants, and 1152 (12.4 %) were return-migrants, respectively. Incidence rates of depression by different migration statuses were 76.6/10³ person-years (73.7/10³-79.7/10³) in non-migrants, 62.9/10³ person-years (55.9/10³-70.6/10³) in permanent migrants, and 67.3/10³ person-years (60.7/10³-74.5/10³) in return-migrants. After controlling for covariates, only permanent migrants had significantly lower incidence of depression than non-migrants (HR: 0.85 (0.75, 0.96)). After stratifying by current place of residence, urban-permanent-migrants had a lower risk of depression than both rural and urban non-migrants, and the HRs and 95%CIs were 0.62 (0.52-0.74) and 0.81 (0.68-0.97).

LIMITATIONS

Migration statuses of participants may have changed over time, but due to the lack of raw data on migration status in 2013 and 2015, we used migration status at baseline. We were also not able to contextualize the migration experiences among those who migrated, and these trajectories may be heterogeneous.

CONCLUSION

Using depression as an indicator of mental health, the healthy migrant hypothesis was supported among middle-aged and elderly permanent migrants living in urban areas while the salmon bias hypothesis was not. Significant urban-rural inequities in mental health existed among different types of migrants. Especially among permanent migrants who have migrated and converted Hukou from their original registration place to their current residence.

Social connectedness as a determinant of mental health: A scoping review

Public health and epidemiologic research have established that social connectedness promotes overall health. Yet there have been no recent reviews of findings from research examining social connectedness as a determinant of mental health. The goal of this review was to evaluate recent longitudinal research probing the effects of social connectedness on depression and anxiety symptoms and diagnoses in the general population. A scoping review was performed of PubMed and PsychInfo databases from January 2015 to December 2021 following PRISMA-ScR guidelines using a defined search strategy. The search yielded 66 unique studies. In research with other than pregnant women, 83% (19 of 23) studies reported that social support benefited symptoms of depression with the remaining 17% (5 of 23) reporting minimal or no evidence that lower levels of social support predict depression at follow-up. In research with pregnant women, 83% (24 of 29 studies) found that low social support increased postpartum depressive symptoms. Among 8 of 9 studies that focused on loneliness, feeling lonely at baseline was related to adverse outcomes at follow-up including higher risks of major depressive disorder, depressive symptom severity, generalized anxiety disorder, and lower levels of physical activity. In 5 of 8 reports, smaller social network size predicted depressive symptoms or disorder at follow-up. In summary, most recent relevant longitudinal studies have demonstrated that social connectedness protects adults in the general population from depressive symptoms and disorders. The results, which were largely consistent across settings, exposure measures, and populations, support efforts to improve clinical detection of high-risk patients, including adults with low social support and elevated loneliness.

The Association between New-Onset Depressive Symptoms and Participating in Medical Check-Ups among Elderly Individuals

The association between adherence to medical check-ups and new-onset depressive symptoms, after adjusting for comprehensive risk factors such as social characteristics, remains unclear. This study aimed to assess the association between mental health and participating in medical check-ups. The survey data of participants aged 60 to 89 were recruited from the seventh Korean Longitudinal Study on Aging. The primary outcome was new-onset depressive symptoms within 2 years measured using the Center for Epidemiologic Studies Depression Scale. Participating in medical check-ups was defined as undergoing biennial medical check-ups. Multivariable logistic regression was performed to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) with consideration of a 2-year time lag. Among 4255 participants, the prevalence of new-onset depressive symptoms was 7.36% (n = 313). The prevalence of non-participation in medical check-ups was 11.96% (n = 509). The adjusted OR of new-onset depressive symptoms by non-participation in medical check-ups was 1.65 [95% CI 1.22-2.24; p = 0.001] after adjusting for various demographic, behavioral, occupational, and social participation characteristics. Our findings demonstrated a significant inverse relationship between participation in medical check-ups and new-onset depressive symptoms. It is necessary to monitor and manage depressive symptoms in vulnerable elderly individuals who do not participate in medical check-ups.

The association between street connectivity and depression among older Japanese adults: the JAGES longitudinal study

Mental health is important in older age; neighborhood environment is considered a protective factor of depression. Research has established that a critical indicator of neighborhood environment, street connectivity, is related to older people's health. However, little is known about the relationship between street connectivity and depression. We examined the relationship between street connectivity and depression among older people. Using Japan Gerontological Evaluation Study 2013-2016, the target population comprised 24,141 independent older people without depression (Geriatric Depression Scale scores below 5) in 2013. The outcome variable was depression in 2016; the explanatory variable was street connectivity calculated by intersection density and space syntax within 800 m around the subject's neighborhood in 2013. We used logistic regression analysis to calculate the odds ratio and 95% confidence interval for the new occurrence of depression among participants in 2016. This analysis demonstrated incidence of new depression after 3 years that is 17% and 14% lower among participations living in high-intersection density and high-street-connectivity areas, respectively, than those living in low-intersection density and low-street-connectivity areas. The association held after adjusting for physical activities and social interaction. Given the established connection between street connectivity and mental health, the findings can contribute to healthy urban planning.

Effects of a nurse-led peer support intervention for stroke survivors: protocol for a randomised controlled trial

INTRODUCTION

Many stroke survivors have unmet psychosocial needs during the recovery phase following a stroke. There is emerging evidence that peer support interventions may play a valuable role in managing stroke. However, evidence regarding the effectiveness of peer support interventions on the psychosocial outcomes of stroke survivors is uncertain. This study aims to develop a nurse-led peer support intervention for stroke survivors based on the Person-Environment-Occupation-Performance Model and evaluate its effects on the psychosocial outcomes of stroke survivors.

METHODS AND ANALYSIS

This is an assessor-blinded two-arm randomised controlled trial. A convenience sample of 120 stroke survivors will be recruited from two community centres and one rehabilitation unit in Yangzhou, a medium-sized city in eastern China, with 60 participants each in the intervention and control groups. The participants allocated to the intervention group will receive the nurse-led peer support intervention, which includes 6 weekly peer support sessions facilitated by a nurse and at least one peer facilitator. Participants randomised to the control group will receive the same dose of interpersonal interaction as intervention participants, including weekly individual face-to-face session for 6 weeks. The primary outcomes are social participation and participation self-efficacy. The secondary outcomes are psychosocial distress, social support, stigma towards disease, self-efficacy in managing chronic conditions and quality of life. Data will be collected at baseline, immediately after the intervention and 3 months after the intervention. A process evaluation will be conducted qualitatively and quantitively to examine the mechanism by which the intervention impacts the psychosocial outcomes of stroke survivors. All outcomes will be analysed following the intention to treat principle. Generalised Estimation Equation models will be used to assess the intervention effect.

ETHICS AND DISSEMINATION

This protocol was approved by the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (CREC Ref. No.: 2021.196-T). All participants will be required to provide written informed consent. Results of the study will be disseminated through publication in peer-reviewed journals and presentation at local or international conferences.

Association of frailty with fall events in older adults: A 12-year longitudinal study in Korea

BACKGROUND

Evidence has shown that frailty is associated with the risk of falls in older people. However, the components of frailty that have the highest association with fall events are largely unknown.

METHODS

This study analyzed panel data from the Korean Longitudinal Study of Aging. We used the Korean Frailty Instrument, which includes domains for social isolation, exhaustion and weakness estimated by grip strength, to assess frailty. Fall event data were collected during follow-up visits.

RESULTS

A total of 3122 community-dwelling adults aged 65 years or older were included at baseline in 2006 and were followed up every 2 years until 2018. The participants with frailty had a higher risk of falls than those without frailty (OR=1.31, 95% CI=1.11-1.54, P = 0.001; fully adjusted model). We found that three components of frailty, namely, social isolation, exhaustion, and weakness, were independently and significantly related to fall events in the unadjusted model. In the fully adjusted model, social isolation and exhaustion were significantly associated with fall events (OR=1.38, 95% CI=1.18-1.61, P < 0.001 and OR=1.28, 95% CI=1.10-1.51, P = 0.006, respectively), and there was no significant association between weakness and the risk of falls (OR=1.11, 95% CI=0.91-1.34, P = 0.307).

CONCLUSIONS AND IMPLICATIONS

Frailty was associated with more fall events in Korean older adults. Social isolation and exhaustion but not weakness were significantly associated with fall events. Our study suggests that interventions should be tailored to older adults with social and psychological frailty.

Factors Associated with Handgrip Strength Among Older Adults in Malaysia

Purpose

Handgrip strength (HGS) is indicative of overall physical health among older adults. A decrease in HGS may be associated with an increased risk of disease. The aim of this study is to determine the factors associated with HGS among older adults in Malaysia.

Patients and Methods

One thousand two hundred four (1204) participants from urban and rural areas in Selangor state, Malaysia, were recruited. Sociodemographic and health-related conditions were gathered through a comprehensive face-to-face interview, followed by HGS assessments by a handgrip dynamometer. Subsequently, multiple linear regression was used to test the main association with the HGS.

Results

A total of 691 participants (57.4%) were male, and 513 (42.6%) were female. Males had a mean HGS of 30.0 (SD 7.53) kg, and females had a mean HGS of 19.4 (SD 5.28) kg. Males’ handgrip strength was significantly reduced with increasing age, physically inactive, and diabetes (all at the level p<0.001) after adjusting for social-demographic characteristics and health-related variables. Meanwhile, for females, the HGS was significantly decreased with age (p<0.001), physically inactive (p<0.001) and hypertension (p=0.03). However, female HGS was positively related to BMI (p<0.001).

Conclusion

The study contributed to a better understanding of factors associated with HGS, and thus, the HGS is recommended as a section in the health evaluation among high-risk older adults as the strategy of disease control and prevention.

Community welfare resources and late-life depression among older adults in Seoul: A multi-level analysis

OBJECTIVES

This study aimed to examine whether community welfare resources in neighborhoods (recreational facilities, healthcare access, and public welfare expenditure) are associated with late-life depression among older adults in Seoul, South Korea.

METHODS

Data for this study were obtained by merging two different data sources: the 2018 Seoul Elderly Survey for individual-level variables and publicly available administrative data for neighborhood-level variables. The sample included 3036 older adults (unweighted n = 3034) living in 25 neighborhoods (Gu) in Seoul. Multilevel regression models examined the effects of neighborhood-level variables on late-life depression while controlling for individual-level variables. We also explored the extent to which individual characteristics moderate the main effects of neighborhood characteristics on late-life depression.

RESULTS

The results indicated that recreational facilities, health care centers, and public welfare expenditure in the neighborhoods were associated with late-life depression among older adults beyond individuals' predisposing conditions. Also, the effects of recreational facilities and public welfare expenditure on depressive symptoms were larger for those with higher education level.

CONCLUSIONS

Older adults living in neighborhoods with more recreational facilities, more health care centers, and high public welfare expenditure were less likely to experience late-life depression. Of note is that the effects of neighborhoods' recreational facilities and public welfare expenditure varied by certain individual characteristics. Hence, local governments should introduce neighborhood-based health promotion policies to prevent depression among older adults. In doing so, local governments should also consider ways to improve access to community welfare resources for underprivileged older adults.

Effects of peer support interventions on physical and psychosocial outcomes among stroke survivors: A systematic review and meta-analysis

BACKGROUND

High level of unmet needs were reported by stroke survivors after hospital discharge. Peer support interventions may play a valuable role in the management of stroke, but the evidence is unclear.

OBJECTIVES

To determine the effects of peer support interventions on physical and psychosocial outcomes of stroke survivors; and to identify the key characteristics of peer support interventions for stroke survivors.cv DESIGN: A systematic review and meta-analysis.

REVIEW METHODS

Seven English databases and four Chinese databases were searched to identify eligible articles. Two reviewers screened the eligible studies, appraised the risk of bias, and extracted the data independently. Version 2 of the Cochrane risk-of-bias tool was used to evaluate the risk of bias for randomized controlled trials, while the Risk of Bias in Non-randomized Studies of Interventions tool was used for the quasi-experimental studies. The Grading of Recommendations Assessment, Development and Evaluation profiler Guideline Development Tool was used to assess the quality of evidence. Meta-analyses were conducted using Review Manager 5.3, and narrative analyses were performed when meta-analysis was inappropriate.

RESULTS

Eleven studies were included. Peer support interventions could improve the activities of daily living (MD = 15.53, 95% CI: 1.39 to 29.68; P = 0.03, I2 = 99%; very low quality of evidence), limb function, depression (SMD = -1.27, 95% CI: -2.18 to -0.36; P = 0.006, I2 = 91%; very low quality of evidence) and anxiety. Although pooled analysis showed that social participation (SMD= 0.74, 95% CI: 0.09 to 1.39; P = 0.03, I2 = 69%; low quality of evidence) and quality of life (SMD = 0.41, 95% CI: 0.09 to 0.73; P = 0.01, I2 = 0%; low quality of evidence) improved after peer support interventions, the studies which were not pooled due to insufficient data drew inconsistent results.

CONCLUSIONS

Stroke survivors may benefit from peer support interventions to improve their physical and psychological outcomes. The evidence about the impact of peer support interventions on social participation and quality of life is very uncertain. It should be noted that the quality of evidence ranged from very low to low, thus highlighting the need for more research of higher quality to substantiate these findings.

Risk factors and protective factors of depression in older people 65+. A systematic review

OBJECTIVES

Identifying risk factors of depression can provide a better understanding of the disorder in older people. However, to minimize bias due to the influence of confounders and to detect reverse influence, a focus on longitudinal studies using multivariate analysis is required.

DESIGN

A systematic literature search was conducted by searching the databases MEDLINE, Cochrane, PsycINFO and Web of Science for all relevant articles published from January 2000 to the end of March 2020. The following inclusion criteria were used: prospective design, nationally or regionally representative sample, published in English or German, analyzed risk factors for depression of individuals 65+ identified by multivariate analysis, and provided validity of diagnostic instrument. All results of multivariate analysis were reported and summarized.

RESULTS

Thirty articles were identified. Heterogeneous results were found for education, female gender, self-rated health, cognitive impairment and older age, although significant in several studies. Findings hinted at a protective quality of physical activity. In terms of physical health, chronic disease and difficulty initiating sleep homogeneously increased risk of depression. Mobility impairment resulted as a risk factor in three studies. IADL impairment and vision impairment were mostly identified as significant risk factors. Alcohol consumption and smoking behavior yielded heterogenous results. Psychosocial factors were assessed similarly in multiple studies and yielded heterogenous results.

LIMITATIONS

Research was limited to articles published in English or German. Length of follow up was not considered for the presentation of results. Adjustments for and inclusion of different variables in the studies may distort results.

CONCLUSION

Our findings demonstrate the necessity of refined, more comparable assessment tools for evaluating potential risk factors.

Association between Proximity of the Elementary School and Depression in Japanese Older Adults: A Cross-Sectional Study from the JAGES 2016 Survey

Depression among older adults is one of the most critical public health issues. The proximity of elementary schools has been positively associated with neighborhood social cohesion and quality of life. However, no studies have identified an association between the proximity of elementary school and older adults' mental health. Therefore, this study aimed to examine the association between the proximity of elementary schools, one of the core facilities of neighborhood communities in Japan, and depression in older adults. A total of 131,871 participants (63,430 men 73.7 ± 6.1 years, 68,441 women 73.8 ± 6.2 years) were analyzed from the Japan Gerontological Evaluation Study (JAGES) 2016 survey. Logistic regression analysis showed that there was no association between distance to elementary school and depression among males. However, among females, compared with the participants living within 400 m from the nearest elementary school, the odds ratio of depression for those living between 400 and 799 m and more than 800 m away were 1.06 (95% confidence interval (CI) 1.00-1.12) and 1.07 (95% CI 1.00-1.15), respectively. The findings may be useful when considering the design of communities around elementary schools and the planning of facilities as a population-based approach to promote mental health of older women.

Mediating effect of social support on the association between life events and depression: A cross-sectional study of adolescents in Chongqing China

Depression is one of the most common mental health problems in adolescents. The link between negative life events and depression has been well established. However, our understanding about the role of social support in the link, which is likely culture-dependent, is quite limited. This study aimed to determine the mediating effect of social support on the association between life events and depression in adolescents in Chongqing China.A total of 1512 adolescents aged 12 to 17 years old in Chongqing of China were selected using a stratified cluster sampling strategy. Depression symptoms, negative life events, and perceived social support of the participants were measured using the Children's Depression Inventory, Adolescent Life Event Scale, and Child and Adolescent Social Support Scale, respectively. Pearson correlation analyses were performed to detect their associations. A multivariate linear regression model was established to determine the association between life events and depression after adjustment for variations in socio-demographic variables. The mediating effect of social support on the association between negative life events and depression was tested using the structural equation model.About 16.8% of the participants were detected with depression. Depression was associated with negative life events and low levels of social support (P < .05). Both frequency and perceived importance of social support showed a mediating effect on the association between life events and depression.Social support has a mediating effect on the association between life events and depression. Strengthening social support may be considered as an effective interventional strategy on depression in adolescents.

The Sense of Coherence, Self-Perception of Aging and the Occurrence of Depression Among the Participants of the University of the Third Age Depending on Socio-Demographic Factors

Purpose

The aim of the study was to assess the relationship between the sense of coherence and self-perception of aging and the risk of depression among attendees of the University of the Third Age (U3A). The influence of socio-demographic factors was studied.

Participants and Methods

The study involved 315 attendees of the U3A aged on average 68.4 years, age range 60–82 years old. The overwhelming majority were women (91.7%). Cross-sectional research was conducted using standardized questionnaires – the SOC-29 scale, the Geriatric Depression Scale (GDS – brief version) and the author’s own questionnaire regarding self-perception of aging.

Results

The study participants showed an average level of sense of coherence (130.7± 23.2). The highest number of people obtained average results of sense of coherence, both in terms of global SOC (75.2%) and its components. The highest scores on the SOC-29 scale were found for the sense of comprehensibility (41.3%). The mean value of the self-perception of aging was 69.0±16.0 and indicates the lower range of results for positive attitude. Nearly ¾ (72.1%) of the respondents had a positive self-perception of aging. The values of the scale of self-perception of aging showed a statistically significant relation to the global level of sense of coherence and its components (p<0.001). In people without depression, positive self-perception of aging was significantly more frequent than among participants with depression of increasing intensity. Education was significantly correlated with the results of the SOC-29 scale, the self-perception of aging scale and the GDS scale.

Conclusion

From the U3A research group, better educated elderly people have a higher sense of coherence and show a more positive self-perception of aging. Moreover, these people are less likely to show signs of senile depression.

Exercise-based interventions for post-stroke social participation: A systematic review and network meta-analysis

BACKGROUND

Resuming participation in society is an important goal of post-stroke rehabilitation. Exercise-based interventions have been shown to be effective non-pharmacological methods for improving social participation in post-stroke survivors, however it is unclear what the most effective types of exercise interventions are.

OBJECTIVE

To assess the comparative effects and ranks of all exercise-based interventions in improving social participations in patients after a stroke.

METHODS

A random-effects network meta-analysis was performed to identify evidence from relevant randomized control trials. We searched MEDLINE, CINAHL, EMBASE, PsycINFO, CINHAL, Cochrane Library, AMED, SPORTDiscus, Web of Science and Clinical Trials.gov from their earliest records to January 2020. Included trials must include at least one types of exercise for patients with stroke. The primary e was social participation. Bias will be assessed according to the revised Cochrane risk of bias tool. Data were analysed using Stata v14.0. Registration number of this study is CRD42020152523.

RESULTS

A total of 16 randomized control trials involving 1704 patients and 12 intervention arms were included in our study. We performed three subgroup analyses divided based on follow up time (1 to <6 months post-treatment, and ≥6 months post-treatment), and intervention adherence. Based on the ranking probabilities, motor relearning programme was ranked as the most effective among all exercise interventions (surface under cumulative ranking curve values [SUCRCV]: 95.6%, standardized mean difference [SMD]: 2.72, 95% confidence interval [CI]: 1.76 to 3.69) in overall and short-term treatment efficacy. In the long-term subgroup, home-based combined exercise ranked the best for the efficacy of social participation improvements among stroke survivors (SUCRCV: 71.8%, SMD: -0.23, 95% CI: -0.61 to 0.15). In the analysis of all interventions with adherence of >90%, cognitive-based exercise ranked the best (SUCRCV: 100%, SMD: 2.64, 95% CI: 1.62 to 3.66).

CONCLUSIONS

Interventions that emerged with the highest ranks in our analysis might be considered in practice when resources allow. More large, well-designed multicentre trials are needed to support the conclusion of this study.

Multi-Level Factors Associated with Social Participation among Stroke Survivors: China's Health and Retirement Longitudinal Study (2011-2015)

Background: This study aims to examine the impact of individual-level and community-based factors on popular social participation activities of Chinese middle-aged and older adults post-stroke. Methods: Sub-samples of survivors of stroke (2011: n = 413, 2013: n = 395, 2015: n = 441) recruited by the China Health and Retirement Longitudinal Study (CHARLS) were included in the analysis. Zero-inflated Poisson and multi-level logistic regression models were used to explore factors associated with social participation. Results: More than half of individuals (55.0%) had no social participation and 23.4% participated in multiple social activities. The most popular social activities that individuals participated in were interacting with friends (32.6%) and going to a community club to play table games (22.7%). Multiple individual-level factors were negatively related to social participation (e.g., depressive symptoms and multiple measures of functional limitations) while the allocation of an outdoor exercise facility in the community/village was positively associated with going to a community club to play table games. Conclusion: Stroke survivors are at high risk of limited social participation. Policymakers and other key stakeholders should consider community design among other potential solutions when identifying ways to link at-risk stroke survivors to both opportunities for rehabilitation (e.g., physical function) and social participation.

Association between social asymmetry and depression in older adults: A phone Call Detail Records analysis

Analyzing social interactions on a passive and non-invasive way through the use of phone call detail records (CDRs) is now recognized as a promising approach in health monitoring. However, deeper investigations are required to confirm its relevance in social interaction modeling. Particularly, no clear consensus exists in the use of the direction parameter characterizing the directed nature of interactions in CDRs. In the present work, we specifically investigate, in a 26-older-adults population over 12 months, whether and how this parameter could be used in CDRs analysis. We then evaluate its added-value for depression assessment regarding the Geriatric Depression Scale score assessed within our population during the study. The results show the existence of three clusters of phone call activity named (1) proactive, (2) interactive, and (3) reactive. Then, we introduce the notion of asymmetry that synthesizes these activities. We find significant correlations between asymmetry and the depressive state assessed in the older individual. Particularly, (1) reactive users are more depressed than the others, and (2) not depressed older adults tend to be proactive. Taken together, the present findings suggest the phone’s potential to be used as a social sensor containing relevant health-related insights when the direction parameter is considered.
