The criterion validity of the Geriatric Depression Scale: a systematic review

Physiological stress in safer cycling in older age (SiFAr-stress): effect of a multicomponent exercise intervention-a study protocol for a randomized controlled trial

BACKGROUND

SiFAr-Stress investigates the impact of cycling on stress levels in older adults. Uncertainty due to change to motorized bicycle or fear of falling can be perceived as stressors for cyclists. Stress activates different physiological signal cascades and stimulates the hypothalamic-pituitary-adrenal (HPA) axis, which leads to the release of the stress hormone cortisol and further effects such as the development of low-grade inflammation. Both can-in the long term-be associated with negative health outcomes. The aim of the study SiFAr-Stress is to analyze inflammatory processes as well as the activity of stress systems before and after a cycling intervention for older adults.

METHODS

In this study, community-dwelling older adults aged 65 years and older will be randomly assigned to either a cycling or a control intervention in a parallel-group design. Objective HPA axis-related measures (saliva cortisol and hair cortisol) will be assessed before, after, and 6-9 months after the cycling and control intervention (T0, T1, and T2). Furthermore, changes in cortisol reactivity in response to the cycling intervention will be investigated at the second and seventh training lessons. Furthermore, secondary outcomes (fear of falling, perceived stress, salivary alpha amylase, and C-reactive protein) will be assessed at T0, T1, and T2.

DISCUSSION

The study will be the first, in which stress- and health-related bio-physiological outcomes will be assessed in the context of a multicomponent exercise intervention, addressing cycling in older adults. It will enable us to better understand the underlying patho-physiological and psychological mechanisms and will help to improve interventions for this target group.

Correlates of institutionalization among the oldest old-Evidence from the multicenter AgeCoDe-AgeQualiDe study

OBJECTIVES

There is a lack of studies identifying the correlates of institutionalization specifically among the oldest old. Therefore, our aim was to fill this gap in knowledge.

METHODS

Cross-sectional data (Follow up wave 9; n = 633 observations in the analytical sample) were used from the multicenter prospective cohort study "Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" Correlates of institutionalization among the oldest old-Evidence from a multicenter cohort study. The sample consists of primary care patients aged 86 years and over (mean 90.5 years, SD: 2.9 years). Sociodemographic and health-related independent variables were included in our regression model. Institutionalization was defined as living in a nursing home or an old-age home (not including assisted living facilities).

RESULTS

Out of the 633 participants, 502 individuals (79.3%) did not live in an institutionalized setting, whereas 73 individuals (20.7%) lived in an institutionalized setting. Multiple logistic regressions showed that the likelihood of institutionalization increased with being divorced/widowed/single (compared to being married; OR: 5.35 [95% CI: 1.75-16.36]), the presence of social isolation (OR: 2.07 [1.20-3.59]), more depressive symptoms (OR: 1.11 [1.01-1.23]), increased cognitive impairment (OR: 1.67 [1.31-2.15]) and higher levels of frailty (OR: 1.48 [1.07-2.06]).

CONCLUSION

The study findings identified various sociodemographic and health-related factors associated with institutionalization among the oldest old. Longitudinal studies are required to gain further insights into these associations.

Effect of Group Cognitive Behavioural Therapy on Loneliness in a Community Sample of Older Adults: A Secondary Analysis of a Randomized Controlled Trial

OBJECTIVES

Research suggests a link between loneliness, depression, and anxiety. Multiple studies have examined treatment programs for loneliness; however, none have examined the efficacy of Cognitive Behavioral Therapy (CBT) for depression and anxiety in reducing loneliness.

METHODS

Change in loneliness in sixty-two older adults (≥60 yrs; 65% female) who took part in a previously reported randomized controlled trial for the treatment of comorbid depression and anxiety was examined. Older adults were randomized to a 12-week group CBT or waitlist control condition. Participants who took part in CBT were followed-up three months later.

RESULTS

Linear Mixed Model analyses indicated that after controlling for baseline cognition, depression, and anxiety, participants who completed CBT experienced a significant decrease in loneliness while the control group did not. This reduction was maintained at follow-up.

CONCLUSIONS

CBT programs for depression and anxiety are likely to be effective at reducing loneliness. This may be due to shared underlying cognitive and behavioral mechanisms between loneliness, depression, and anxiety such as sensitivity to perceived threat and social withdrawal. Further research is needed to understand if specific loneliness interventions are more effective.

CLINICAL IMPLICATIONS

CBT may be effective at reducing loneliness among older adults with depression and anxiety.

Long-term relapse rates after cognitive behaviour therapy for anxiety and depressive disorders among older adults: A follow-up study during COVID-19

OBJECTIVE

This study assessed the long-term symptom relapse rates among older adults previously treated with cognitive behaviour therapy (CBT) for anxiety and/or depression during COVID-19.

METHODS

Participants were 37 older adults (M = 75 years, SD = 5; 65% female) previously treated with CBT for anxiety and/or unipolar depression who were re-assessed an average of 5.6 years later, during the first Australian COVID-19 lockdown.

RESULTS

On average, there was no significant group-level change in anxiety, depression or quality of life. When assessing change in symptoms based on clinical cut-off points on self-report measures, results suggest only 17%-22% showed a relapse of symptoms by the COVID-19 pandemic.

CONCLUSIONS

Findings suggest that CBT may be protective in coping with life stressors many years after treatment ends. However, results warrant replication to attribute continued symptom improvement to CBT given the lack of control group.

Collagenase Clostridium histolyticum Injection Therapy Improves Health-related Quality of Life in Patients with Dupuytren's Disease

Objectives:

This study was conducted to investigate the changes in clinical and psychosocial outcomes in patients with Dupuytren’s disease after initial treatment with collagenase Clostridium histolyticum (CCH) injection.

Methods:

This study involved 14 patients with Dupuytren’s disease who underwent treatment with CCH injection. The range of motion of each phalangeal joint was measured before treatment and at 6 months posttreatment. The following assessments were also carried out pre- and posttreatment: the Geriatric Depression Scale Short – Japanese version (GDS-J) to evaluate depressive status, Hand 10 to assess hand health status, and EuroQol-5-dimension-3-level Japanese version to evaluate health-related quality of life

Results:

Significant improvements were found in metacarpophalangeal joint extension and proximal interphalangeal joint extension. Significant differences were also found between values before the initiation of CCH injection and those at 6 months posttreatment for the EuroQol index score and the EuroQol Visual Analog Scale (VAS). Significant positive correlations were found between the pre- to posttreatment change in GDS-J scores and for the change in Hand 10 scores. Moreover, a significant negative correlation was found between the change in GDS-J scores and change in EuroQol index scores/EuroQol VAS scores before and at 6 months after CCH injection.

Conclusions:

For patients with Dupuytren’s disease, CCH therapy directly improved the health-related quality of life. The degree of improvement of depressive status was associated with the degree of improvement of hand health status and health-related quality of life.

Is geriatric depression scale a valid instrument to screen depression in Chinese community-dwelling elderly?

BACKGROUND

The geriatric depression scale (GDS) is used widely as a screening instrument for depression worldwide. The present study aims to examine the reliability and validity of the GDS with 30 items (GDS-30) in Chinese cognitively normal elderly, and to preliminarily investigate the appropriateness of the GDS-30 among screened mild cognitive impairment (MCI) elderly and among the large-scale community-dwelling Chinese elderly.

METHODS

A total of 12,610 Chinese elderly completed GDS-30 in the project of Community-based Cohort Study on Nervous System Diseases. Of these, 5503 individuals with the ability to perform basic daily living activities were randomly sampled to further complete the Montreal Cognitive Assessment to screen for MCI. The cutoff value of screened depression was 11, and the cutoff values of MCI were education-dependent. Internal consistency was used to evaluate the reliability. Exploratory factor analysis (EFA) was used to determine the factor structure. Confirmatory factor analysis (CFA) was conducted to assess the construct validity in the elderly screened normal cognition, screened MCI, and the whole population, respectively.

RESULTS

The Kuder-Richardson coefficient (KR20) was 0.834, 0.821 and 0.840 for the cognitively normal elderly, screened MCI and the whole population, respectively. EFA showed that GDS-30 can be either a four-factor model (named positive mood, dysphoria, worry, and social withdrawal-cognitive impairment) or a two-factor model (named depression and positive mood). The latter was easier to interpret. CFA showed that the two-factor model fitted well in the elderly with normal cognition, with screened MCI, and the whole sample. The factors loaded from 0.900 to 0.588, 0.882 to 0.529, and 0.888 to 0.556 in these three populations respectively.

CONCLUSIONS

The GDS-30 has good reliability and validity and can be appropriately applied to screen depression in the large-scale community-dwelling Chinese elderly regardless of the presence of mild cognitive impairment.

Sex-Specific Associations Between Depressive Symptoms and Risk for Subsequent Dementia

BACKGROUND

An association between depression and an increased risk for subsequent dementia is well-established. Sexspecific associations are understudied yet.

OBJECTIVE

We aimed to investigate sex-specific associations between depressive symptoms and dementia risk.

METHODS

Longitudinal analyses were conducted in a pooled data set (n = 4,255, mean age = 80 years) of two prospective cohort studies (LEILA 75+, AgeCoDe). Depressive symptoms were harmonized by dichotomized scores of two different depression screening scales using established cutoffs. Transition to dementia was used as outcome in Cox proportional hazards models.

RESULTS

Depressive symptoms at baseline were associated with an increased risk for subsequent dementia, and this association was more pronounced in males (interaction of depressive symptoms × sex: HR = 1.64, 95% CI: 1.02-2.64, p = 0.042) in a model adjusted for study, age, and education. After additional adjustment for subjective and objective cognition, depressive symptoms and their interaction with sex (HR = 1.38, 95% CI: 0.85-2.23, p = 0.188) were no longer significantly associated with the risk for subsequent dementia. Sex-stratified analyses showed stronger and significant associations between depressive symptoms and subsequent dementia in men (e.g., HR= 2.10, 95% CI: 1.36-3.23, p = 0.001, compared to HR= 1.28, 95% CI: 1.04-1.58, p = 0.020, in women).

CONCLUSIONS

Overall, we provide evidence for a stronger association between depression and dementia in men compared to women. Depressive symptoms should be diagnosed, monitored, and treated, not only due to depression, but also with respect to the risk for subsequent dementia, especially in elderly men.

Validation of the Parkinson's Disease Caregiver Burden Questionnaire in Progressive Supranuclear Palsy

Progressive supranuclear palsy (PSP) is an atypical Parkinson syndrome with axial akinetic-rigid symptoms, early postural instability, and ocular motor impairments. Patients experience a rapid loss of autonomy and care dependency; thus, caregivers must assist in the activities of daily living early in the course of the disease. Caregiver burden is an extremely important factor in disease management. However, there are no specific questionnaires for assessment of caregiver burden in PSP. This study aims to validate the Parkinson's disease caregiver burden questionnaire (PDCB) as a specific measure of caregiver burden in PSP. PSP patients were assessed by the PSP rating scale, PSP quality-of-life questionnaire (PSP-QoL), Montreal cognitive assessment test (MoCA), and geriatric depression scale (GDS-15). Caregivers filled out the short form 36-health survey, GDS-15, PDCB, and the caregiver burden inventory (CBI). 22 patient caregiver pairs completed the study. PDCB showed a highly significant correlation with the CBI (r 0.911; p < 0.001). Internal reliability of the PDCB measured by Cronbach's alpha was favourable at 0.803. These data support the specificity of the PDCB in PSP caregivers. Future studies with larger sample sizes of PSP patients and caregivers and a multicentric longitudinal design should be performed to gain further insight of caregiver burden in PSP.

Associations Between Fear of COVID-19, Affective Symptoms and Risk Perception Among Community-Dwelling Older Adults During a COVID-19 Lockdown

Fear is a common and potentially distressful psychological response to the current COVID-19 pandemic. The factors associated with such fear remains relatively unstudied among older adults. We investigated if fear of COVID-19 could be associated with a combination of psychological factors such as anxiety and depressive symptoms, and risk perception of COVID-19, and demographic factors in a community sample of older adults. Older adults (N = 413, M age = 69.09 years, SD = 5.45) completed measures of fear of COVID-19, anxiety and depressive symptoms, and risk perception of COVID-19, during a COVID-19 lockdown. These variables, together with demographics, were fitted to a structural equation model. Anxiety and depressive symptoms were highly correlated with each other and were combined into the higher order latent variable of affective symptoms for analyses. The final model revealed that fear of COVID-19 was positively associated with psychological factors of affective symptoms and risk perception. Older age was associated with greater fear of COVID-19. Our findings showed that fear of COVID-19 can be a projection of pre-existing affective symptoms and inflated risk perceptions and highlighted the need to address the incorrect risk perceptions of COVID-19 and socio-affective issues among older adults in the community.

Reliability and validation of the Positive Aspects of Caregiving scale among Japanese caregivers of people with dementia

Objectives

This study aimed to validate the Positive Aspects of Caregiving(PAC) scale's psychometric properties among Japanese informal caregivers of people with dementia.

Methods

A cross-sectional research design was used. Data were collected from the Kinki region of Japan during January 2019 and July 2019. Translation and back-translation were performed to acquire the optimal translation of the PAC scale. In total, 194 participants responded to questionnaires that included the Japanese version of the PAC scale and the Geriatric Depression Scale (GDS). Reliability was evaluated by examining the internal consistency and test-retest reliability. Exploratory factor analysis with maximum likelihood estimation and oblique rotation was performed to assess the PAC scale structure. Concurrent validity was determined using Pearson's correlation coefficient.

Results

The final version of the Japanese version of the PAC scale contained nine items. Exploratory factor analysis revealed two factors (Living an enriched life and Self-usefulness). The Cronbach's ⍺ coefficient of the total scale was 0.895, the subscales Cronbach's ⍺ coefficient were 0.896 and 0 .823. The intraclass correlation coefficient for test-retest reliability was 0.721, indicating acceptable reliability. PAC was significantly correlated to GDS (r = -0.548, P < 0.01).

Conclusions

This study found that the Japanese version of the PAC scale was a suitable scale to measure PAC among Japanese caregivers of people with dementia. However, the construct differed from the original model. This scale could help health-care professionals understand the degree of caregivers' recognition about dementia care and support those with a low degree of positive aspects of caregiving.

Frailty and Autonomy among the Oldest Old: Evidence from the Multicenter Prospective AgeCoDe-AgeQualiDe Study

INTRODUCTION

There is a lack of studies examining the link between perceived autonomy and frailty among the oldest old. Therefore, our objective was to fill this gap.

METHODS

Data were used from the multicenter prospective cohort study "Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" (AgeQualiDe; follow-up [FU] wave 9; n = 510 observations in the analytical sample). The average age was 90.3 years (SD: 2.7 years). The Canadian Study of Health and Aging (CSHA) Clinical Frailty Scale (CFS) was used to assess frailty. Socioeconomic and health-related covariates were included in our regression model. The autonomy scale developed by Schwarzer was used to assess perceived autonomy in old age.

RESULTS

Adjusting for various confounders, multiple linear regressions showed that lower perceived autonomy was associated with increased levels of frailty (total sample: β = -0.13, p < 0.001; women: β = -0.14, p < 0.001; and men: β = -0.12, p < 0.001). Furthermore, lower perceived autonomy was associated with more depressive symptoms, higher cognitive impairment, and being institutionalized (except for men) in the total sample and in both sexes, but it was not significantly associated with age, sex, marital status, educational level, and social support.

CONCLUSION

Findings indicate that frailty is associated with lower autonomy among the oldest old. More generally, while health-related factors were consistently associated with autonomy, sociodemographic factors (except for being institutionalized) were not associated with autonomy among the oldest old. We should be aware of the strong association between autonomy and physical as well as mental health in very old age.

Association of quality of life with structural, functional and molecular brain imaging in community-dwelling older adults

BACKGROUND

As the population ages, maintaining mental health and well-being of older adults is a public health priority. Beyond objective measures of health, self-perceived quality of life (QoL) is a good indicator of successful aging. In older adults, it has been shown that QoL is related to structural brain changes. However, QoL is a multi-faceted concept and little is known about the specific relationship of each QoL domain to brain structure, nor about the links with other aspects of brain integrity, including white matter microstructure, brain perfusion and amyloid deposition, which are particularly relevant in aging. Therefore, we aimed to better characterize the brain biomarkers associated with each QoL domain using a comprehensive multimodal neuroimaging approach in older adults.

METHODS

One hundred and thirty-five cognitively unimpaired older adults (mean age ± SD: 69.4 ± 3.8 y) underwent structural and diffusion magnetic resonance imaging, together with early and late florbetapir positron emission tomography scans. QoL was assessed using the brief version of the World Health Organization's QoL instrument, which allows measuring four distinct domains of QoL: self-perceived physical health, psychological health, social relationships and environment. Multiple regression analyses were carried out to identify the independent global neuroimaging predictor(s) of each QoL domain, and voxel-wise analyses were then conducted with the significant predictor(s) to highlight the brain regions involved. Age, sex, education and the other QoL domains were entered as covariates in these analyses. Finally, forward stepwise multiple regressions were conducted to determine the specific items of the relevant QoL domain(s) that contributed the most to these brain associations.

RESULTS

Only physical health QoL was associated with global neuroimaging values, specifically gray matter volume and white matter mean kurtosis, with higher physical health QoL being associated with greater brain integrity. These relationships were still significant after correction for objective physical health and physical activity measures. No association was found with global brain perfusion or global amyloid deposition. Voxel-wise analyses revealed that the relationships with physical health QoL concerned the anterior insula and ventrolateral prefrontal cortex, and the corpus callosum, corona radiata, inferior frontal white matter and cingulum. Self-perceived daily living activities and self-perceived pain and discomfort were the items that contributed the most to these associations with gray matter volume and white matter mean kurtosis, respectively.

CONCLUSIONS

Better self-perceived physical health, encompassing daily living activities and pain and discomfort, was the only QoL domain related to brain structural integrity including higher global gray matter volume and global white matter microstructural integrity in cognitively unimpaired older adults. The relationships involved brain structures belonging to the salience network, the pain pathway and the empathy network. While previous studies showed a link between objective measures of physical health, our findings specifically highlight the relevance of monitoring and promoting self-perceived physical health in the older population. Longitudinal studies are needed to assess the direction and causality of the relationships between QoL and brain integrity.

Engaging in pleasant events explains the relation between physical disability and mental health outcomes in older adults

OBJECTIVES

This study expands the body of research examining mediators of the association between physical disability and mental health outcomes. Based on the behavioral model of depression, frequency of pleasant events were examined as a mediator between physical disability and mental health outcomes including depressive symptoms, meaning in life, and positive affect. We predicted that physical disability would have a significant indirect effect on mental health outcomes through the lower frequency of pleasant events.

METHODS

Cross-sectional study of 82 community-dwelling adults, M_age = 77.6, SD = 8.0, 64.6% female, was conducted. Self-report instruments measured frequency of pleasant events, physical disability, and mental health outcomes (depression symptoms, positive affect, and meaning in life).

RESULTS

Simple mediation analyses demonstrated a significant indirect effect of physical disability on depressive symptoms (unstandardized coefficient = 0.16, 95% bias-corrected CI 0.03, 0.41), positive affect (unstandardized coefficient = -2.65, 95% bias-corrected CI -5.38, -0.88), and meaning in life (unstandardized coefficient = -1.58, 95% bias-corrected CI -3.19, -0.47) through engagement in pleasant events.

CONCLUSION

Physical disability was associated with greater depressive symptoms and lower positive affect and meaning in life through reduced frequency of pleasant events. These findings are consistent with the behavioral model of depression and support several applied recommendations for reducing the burden of physical disability on mental health outcomes.

The association between home ownership and the health of older men: Cross-sectional analysis of the Australian Concord Health and Ageing in Men Project

OBJECTIVE

To investigate the association between home ownership and health in older men.

METHODS

Cross-sectional analysis of 909 community-dwelling Australian men (mean age: 81.3 ± 4.6) from the Concord Health and Ageing in Men Project (CHAMP, 2012-2013). We considered self-rated health, frailty status, multimorbidity, and anxiety and depressive symptoms which identify different dimensions of health.

RESULTS

Most participants were owner-occupiers (89.7%). In age- and country of birth-adjusted analyses, not being an owner-occupier was associated with an increased likelihood of depressive symptoms [prevalence ratio: 1.82, 95% confidence intervals 1.17 to 2.84]. There were no associations between home ownership and other health conditions.

CONCLUSION

Lack of home ownership was associated with a higher prevalence of depressive symptoms, largely explained by poorer social support. Thus, targeting mental health programs at older divorced or separated men who do not own their own home could be an appropriate community-based intervention.

Different dimensions of social support differentially predict psychological well-being in late life: opposite effects of perceived emotional support and marital status on symptoms of anxiety and of depression in older outpatients in Italy

BACKGROUND

Social support is important to psychological well-being in late life. However, findings in the literature regarding its effects are mixed, less information is available for anxiety than for depressive symptoms, and few studies have been carried out in Italy. Therefore, the aim of this study was to investigate the influence of social support on symptoms of anxiety and of depression in a sample of geriatric outpatients in Italy.

METHODS

This cross-sectional study consecutively enrolled 299 outpatients without dementia (age ≥ 65, all neuropsychologically tested). Social support was assessed with the ENRICHD Social Support Instrument and by interview. Symptoms of anxiety and of depression were evaluated with short versions of the State-Trait Personality Inventory Trait Anxiety and Geriatric Depression scales. The relationship between social support and psychological well-being was examined by multiple linear regression models with socio-demographic and clinical variables, including cognitive performance, as potential confounders.

RESULTS

Perceived emotional support was a negative predictor of symptoms of anxiety (standardised beta coefficient (β) -0.288, standard error (SE) 0.074, P < 0.001) and symptoms of depression (β -0.196, SE 0.040, P < 0.001). On the contrary, marital status (i.e. being married) was a positive predictor of symptoms of anxiety (β 0.199, SE 0.728, P = 0.003) and symptoms of depression (β 0.142, SE 0.384, P = 0.035).

CONCLUSIONS

Different dimensions of social support differentially affect psychological well-being. The protective effect of perceived emotional support is consistent with social cognitive models of health. The harmful effect of being married may be capturing the distress of the pre-bereavement period. Alternatively, it may reflect oppression by gender roles within marriage in a predominantly female sample in a traditional society. Our findings provide insight into the relationship between social support and psychological well-being, and identify potential targets for psychosocial interventions promoting mental health in late life.

An Initial Empirical Operationalization of the Earliest Stages of the Alzheimer's Continuum

PURPOSE

The Alzheimer's Continuum (AC) includes 2 preclinical stages defined by subjective cognitive complaints, transitional cognitive declines, and neurobehavioral symptoms. Operationalization of these stages is necessary for them to be applied in research.

METHODS

Cognitively normal individuals with known amyloid biomarker status were selected from the National Alzheimer's Coordinating Center Uniform Data Set. Participants and their caregivers provided information on subjective cognitive complaints, neurobehavioral features, and objective cognitive functioning.

PATIENTS

The sample included 101 amyloid positive (A+) and 447 amyloid negative (A-) individuals.

RESULTS

Rates of subjective cognitive complaints (A+: 34.90%, A-: 29.90%) and neurobehavioral symptoms (A+: 22.40%, A-: 22.40%) did not significantly differ between A+/- individuals. However, the frequency of transitional cognitive decline was significantly higher among A+ (38.00%) than A- participants (24.90%). We explored various empirical definitions for defining the early stages of the AC among A+ participants. Rates of classification into AC stage 1 versus AC stage 2 varied depending on the number of symptoms required: 57.40% versus 42.60% (1 symptom), 28.70% versus 71.30% (2 symptoms), and 6.90% versus 93.10% (all 3 symptoms).

CONCLUSION

The presence of 2 of the proposed symptom classes to separate AC stage 2 from stage 1 seems to provide a good empirical balance.

Association Between Upper-Extremity Health Condition and Depressive Status in an Elderly General Population

Background: This study was designed to investigate whether psychological status is associated with upper-extremity health status in an elderly general population. Methods: Using Quick Disabilities of the Arm, Shoulder, and Hand of the Japanese Society for Surgery of the Hand (QuickDASH-JSSH), we evaluated 200 Japanese elderly people (76 men, 124 women; mean age, 71.6 years, 60-98 years) to assess their upper-extremity-specific health status. Each had completed a self-administered questionnaire including gender and dominant hand items. As an indicator of hand muscle function, we measured their bilateral hand grip. Study participants were assessed for depressive symptoms using the Geriatric Depression Scale Short-Japanese Version (GDS-S-J). Statistical analyses were applied to clarify associations between self-assessed upper-extremity dysfunction and screening results for depressive symptoms in an elderly general population. Results: Those reporting no complaint of an upper extremity were 72 (36 men and 36 women) (36.0%). The GDS-J score was found to have significant positive correlation with age (r = 0.20, P= 0.0045) and the QuickDASH score (r = 0.25, P = 0.0004). The GDS-J score was found to have significant negative correlation with dominant grip (r = −0.15, P = 0.04) and non-dominant grip strength (r = −0.21, P = 0.004). For all participants, multiple regression analysis revealed the QuickDASH score as associated with the GDS-J score. Conclusion: Self-administered upper-extremity health condition as assessed using QuickDASH is correlated with depressive symptoms in elderly people. Objective pathophysiology and subjective illness behavior must be identified in daily clinical practice. A biopsychosocial approach must be used when advising and treating patients.

Frailty and depression predict instrumental activities of daily living in older adults: A population-based longitudinal study using the CARE75+ cohort

Objectives

To evaluate if depression contributes, independently and/or in interaction with frailty, to loss of independence in instrumental activities of daily living (ADL) in older adults with frailty.

Methods

Longitudinal cohort study of people aged ≥75 years living in the community. We used multi-level linear regression model to quantify the relationship between depression (≥5 Geriatric Depression Scale) and frailty (electronic frailty index), and instrumental activities of daily living (Nottingham Extended Activities of Daily Living scale; range: 0–66; higher score implies greater independence). The model was adjusted for known confounders (age; gender; ethnicity; education; living situation; medical comorbidity).

Results

553 participants were included at baseline; 53% were female with a mean age of 81 (5.0 SD) years. Depression and frailty (moderate and severe levels) were independently associated with reduced instrumental activities of daily living scores. In the adjusted analysis, the regression coefficient was -6.4 (95% CI: -8.3 to -4.5, p<0.05) for depression, -1.5 (95% CI: -3.8 to 0.9, p = 0.22) for mild frailty, -6.1 (95% CI: -8.6 to -3.6, p<0.05) for moderate frailty, and -10.1 (95% CI: -13.5 to -6.8, p<0.05) for severe frailty. Moreover, depression interacted with frailty to further reduce instrumental activities of daily living score in individuals with mild or moderate frailty. These relationships remained significant after adjusting for confounders.

Conclusion

Frailty and depression are independently associated with reduced independence in instrumental activities of daily living. Also, depression interacts with frailty to further reduce independence for mild to moderately frail individuals, suggesting that clinical management of frailty should integrate physical and mental health care.

A New Social Network Scale for Detecting Depressive Symptoms in Older Japanese Adults

Social engagement and networking deter depression among older adults. During the COVID-19 pandemic, older adults are especially at risk of isolation from face-to-face and non-face-to-face interactions. We developed the National Center for Geriatrics and Gerontology Social Network Scale (NCGG-SNS) to assess frequency of, and satisfaction with, social interactions. The NCGG-SNS consists of four domains: face-to-face/non-face-to-face interactions with family/friends. Each domain score is obtained by multiplying frequency ratings by satisfaction ratings for each item; all scores were summed to obtain a total NCGG-SNS score (range: 0–64). Additionally, face-to-face and non-face-to-face subscores were calculated. Higher scores indicated satisfactory social networking. A cohort of 2445 older Japanese adults completed the NCGG-SNS and the Geriatrics Depression Scale-Short form. Receiver Operating Characteristic (ROC) analysis and logistic regression determined predictive validity for depressive symptoms. Depressive symptoms were reported by 284 participants (11.6%). The optimal NCGG-SNS cut-off value to identify depressive symptoms was 26.5 points. In logistic regression analysis adjusted for potential confounders, lower NCGG-SNS values were significantly associated with greater prevalence of depressive symptoms. Face-to-face and non-face-to-face subscores were associated with depressive symptoms. The NCGG-SNS is a valid and useful indicator of multidimensional social networking enabling identification of depressive symptoms in older adults.

Elevated Procalcitonin as a Risk Factor for Postoperative Delirium in the Elderly after Cardiac Surgery-A Prospective Observational Study

One of the most common complications after cardiac surgery with cardiopulmonary bypass (CBP) is delirium. The purpose of this study was to prospectively investigate the risk of developing postoperative delirium in a group of elderly patients using a multivariate assessment of preoperative and intraoperative risk factors. A total of 149 elderly patients were included. Thirty patients (20%) developed post-operative delirium. Preoperative procalcitonin (PCT) above the reference range (>0.05 ng/mL) was recorded more often in patients who postoperatively developed delirium than in the non-delirium group (50% vs. 27%, p = 0.019). After surgery, PCT was significantly higher in the delirium than the non-delirium group: ICU admission after surgery: 0.08 ng/mL vs. 0.05 ng/mL p = 0.011), and for consecutive days (day 1: 0.59 ng/mL vs. 0.25 ng/mL, p = 0.003; day 2: 1.21 ng/mL vs. 0.36 ng/mL, p = 0.006; day 3: 0.76 ng/mL vs. 0.34 ng/mL, p = 0.001). Patients with delirium were older (74 vs. 69 years, p = 0.038), more often had impaired daily functioning (47% vs. 28%, p = 0.041), depressive symptoms (40% vs. 17%, p = 0.005), and anemia (43% vs. 19%, p = 0.006). In a multivariable logistic regression model, preoperative procalcitonin (odds ratio (OR) = 3.05), depressive symptoms (OR = 5.02), age (OR = 1.14), impaired daily functioning (OR = 0.76) along with CPB time (OR = 1.04) were significant predictors of postoperative delirium.

Dietary patterns and depression risk in older adults: systematic review and meta-analysis

CONTEXT

Diet may be one of the modifiable environmental factors that could reduce depressive symptoms or abate the development of depression without side effects. However, previous reviews mainly focused on general adult populations.

OBJECTIVE

The aim of this systematic review and meta-analysis was to explore the association between healthy dietary patterns and depression risk in older adults.

DATA SOURCES

Eight databases were searched up to September 2019. The inclusion criteria were older adults aged ≥ 65 years, healthy dietary patterns, depression assessed by a physician or by validated screening tools, and quantitative study design.

DATA EXTRACTION

Data were extracted independently by 2 researchers, and the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline was followed.

DATA ANALYSIS

Meta-analysis was conducted by calculating the pooled odds ratio (OR) and 95% CIs. A total of 18 eligible studies were meta-analyzed. Results showed that a healthy dietary pattern is associated with a reduced risk of depression in older adults (OR, 0.85; 95%CI, 0.78-0.92; P < 0.001). There was high heterogeneity (I2 = 64.9%; P < 0.001) among the studies. Subgroup analyses indicated that sample size and depression screening tools were the main sources of study heterogeneity.

CONCLUSIONS

An inverse association between healthy dietary patterns and depression risk in older adults was found. However, the high heterogeneity among the studies should be considered.

Depressive Symptoms and Frailty Among the Oldest Old: Evidence from a Multicenter Prospective Study

OBJECTIVE

There is a lack of studies disentangling whether changes in frailty are associated with subsequent changes in depressive symptoms or vice versa among the oldest old. Consequently, we aimed to disentangle this link.

DESIGN

Three waves [follow-up (FU) wave 7 to FU wave 9; n = 423 individuals in the analytical sample] were used from the multicenter prospective cohort study "Needs, Health Service Use, Costs and Health-Related Quality of Life in a Large Sample of Oldest-Old Primary Care Patients (85+)" (AgeQualiDe).

SETTING AND PARTICIPANTS

Primary care patients aged 85 years and older.

METHODS

The Canadian Study of Health and Aging (CSHA) Clinical Frailty Scale (CFS) was used to quantify frailty, and the Geriatric Depression Scale was used to measure depressive symptoms. It was adjusted for several covariates (sociodemographic and health-related factors) in regression analysis.

RESULTS

Multiple linear regressions with first differences showed that initial increases in depressive symptoms (from FU wave 7 to FU wave 8) were associated with subsequent increases in frailty (from FU wave 8 to FU wave 9; β = 0.06, P < .05), whereas initial increases in frailty (from FU wave 7 to FU wave 8) were not associated with subsequent increases in depressive symptoms (from FU wave 8 to FU wave 9).

CONCLUSIONS AND IMPLICATIONS

The study findings suggest the relevance of increases in depressive symptoms for subsequent increases in frailty. Treatment of depressive symptoms may also be beneficial to postpone frailty.

A cross-national study of depression in preclinical dementia: A COSMIC collaboration study

INTRODUCTION

Depression commonly accompanies Alzheimer's disease, but the nature of this association remains uncertain.

METHODS

Longitudinal data from the COSMIC consortium were harmonized for eight population-based cohorts from four continents. Incident dementia was diagnosed in 646 participants, with a median follow-up time of 5.6 years to diagnosis. The association between years to dementia diagnosis and successive depressive states was assessed using a mixed effect logistic regression model. A generic inverse variance method was used to group study results, construct forest plots, and generate heterogeneity statistics.

RESULTS

A common trajectory was observed showing an increase in the incidence of depression as the time to dementia diagnosis decreased despite cross-national variability in depression rates.

DISCUSSION

The results support the hypothesis that depression occurring in the preclinical phases of dementia is more likely to be attributable to dementia-related brain changes than environment or reverse causality.

Contribution of psychosocial factors to socioeconomic inequalities in mortality among older Australian men: a population-based cohort study

BACKGROUND

Among older people, the extent to which psychosocial factors explain socioeconomic inequalities in mortality is debated. We aimed to investigate the potential mediating effect of psychosocial factors on socioeconomic inequalities in mortality.

METHODS

We used data from a prospective population-based cohort (the Concord Health and Ageing in Men Project; baseline recruitment in 2005-2007), in Sydney, Australia. The main outcomes were all-cause and cause-specific mortality. Socioeconomic status (SES; educational attainment, occupational position, source of income, housing tenure, and a cumulative SES score) was assessed at baseline. Measures of structural and functional social support, as well as depressive and anxiety symptoms were assessed three times during follow-ups. Associations were quantified using Cox regression. Mediation was calculated using "change-in-estimate method".

RESULTS

1522 men (mean age at baseline: 77·4 ± 5·5 years) were included in the analyses with a mean (SD) follow-up time of 9·0 (3·6) years for all-cause and 8·0 (2·8) years for cause-specific mortality. At baseline, psychosocial measures displayed marked social patterning. Being unmarried, living alone, low social interactions, and elevated depressive symptoms were associated with higher risk of all-cause and cardiovascular disease (CVD) mortality. Psychosocial factors explained 35% of SES inequalities in all-cause mortality, 29% in CVD mortality, 12% in cancer mortality, and 39% in non-CVD, non-cancer mortality.

CONCLUSION

Psychosocial factors may account for up to one-third of SES inequalities in deaths from all and specific causes (except cancer mortality). Our findings suggest that interventional studies targeting social relationships and/or psychological distress in older men aiming to reduce socioeconomic inequalities in mortality are warranted.

Is kidney function associated with cognition and mood in late life? : The Screening for CKD among Older People across Europe (SCOPE) study

Background

Chronic kidney disease (CKD), cognitive impairment and depression share common risk factors. Previous studies did not investigate the possible association between kidney function and cognitive and mood disorders in older persons in a broad range of kidney function. The present study explored associations between kidney function, cognition and mood in outpatients of 75 years and over.

Methods

Baseline data of 2252 participants of the SCOPE study, an international multicenter cohort observational study,were used in which community-dwelling persons of 75 years and over were enrolled to screen for CKD Kidney function was estimated with the BIS1-eGFR equation, cognition was assessed with the Mini-Mental State Examination (MMSE) and mood with the Geriatric Depression Scale 15 items (GDS-15). Characteristics were compared across stages of CKD. Mean eGFR values were also compared across categories of MMSE (< 24, 24–26, ≥27) and between groups with high and low score on the GDS-15 (> 5/≤5).

Results

In total, 63% of the population had an eGFR < 60 mL/min. In advanced stages of CKD, participants were older and more often men than in earlier stages (p < 0.001). Cardiovascular diseases and diabetes mellitus were more often found in those in advanced stages of CKD (p < 0.001), and also cumulative comorbidity scores were higher than in those in earlier stages (p < 0.001). Median MMSE was 29 in CKD stage 1–2 and 3, and 30 in CKD stage 4, whereas median GDS-15 score was 2 in all stages of CKD. Mean values of eGFR did not differ across categories of MMSE or between groups with high and low score on the GDS-15. Stratification for albuminuria did not change these results.

Conclusions

Older persons in more advanced stages of CKD did not have lower cognitive scores or higher rates of depressive symptoms than older persons in earlier stages. Future longitudinal studies might give information on the possible effect of kidney function on cognition and mood in late life.

Trial registration

This study was registered prospectively on 25th February 2016 at clinicaltrials.gov (NCT02691546).

Cluster Analysis of the Associations among Physical Frailty, Cognitive Impairment and Mental Disorders

Background

Physical frailty, cognitive impairment, and symptoms of anxiety and depression frequently co-occur in later life, but, to date, each has been assessed separately. The present study assessed their patterns in primary care patients aged ≥60 years.

Material/Methods

This cross-sectional study evaluated 263 primary care patients aged ≥60 years in eastern Croatia in 2018. Physical frailty, cognitive impairment, anxiety and depression, were assessed using the Fried phenotypic model, the Mini-Mental State Examination (MMSE), the Geriatric Anxiety Scale (GAS), and the Geriatric Depression Scale (GDS), respectively. Patterns were identified by latent class analysis (LCA), Subjects were assorted by age, level of education, and domains of psychological and cognitive tests to determine clusters.

Results

Subjects were assorted into four clusters: one cluster of relatively healthy individuals (61.22%), and three pathological clusters, consisting of subjects with mild cognitive impairment (23.95%), cognitive frailty (7.98%), and physical frailty (6.85%). A multivariate, multinomial logistic regression model found that the main determinants of the pathological clusters were increasing age and lower mnestic functions. Lower performance on mnestic tasks was found to significantly determine inclusion in the three pathological clusters. The non-mnestic function, attention, was specifically associated with cognitive impairment, whereas psychological symptoms of anxiety and dysphoria were associated with physical frailty.

Conclusions

Clustering of physical and cognitive performances, based on combinations of their grades of severity, may be superior to modelling of their respective entities, including the continuity and non-linearity of age-related accumulation of pathologic conditions.

Determinants of Cross-Sectional and Longitudinal Health-Related Quality of Life in Memory Clinic Patients Without Dementia

OBJECTIVE

To identify determinants within 3 different domains (ie, somatic comorbidities, cognitive functioning, and neuropsychiatric symptoms [NPS]) of health-related quality of life (HRQoL) over time in memory clinic patients without dementia.

METHODS

This longitudinal multicenter cohort study with a 3-year observation period recruited 315 individuals (age: 69.8 ± 8.6, 64.4% males, Mini-Mental State Examination score 26.9 ± 2.6). A multivariable explanatory model was built using linear mixed effects models (forward selection per domain) to select determinants for self-perceived HRQoL over time, as measured by the EuroQoL-5D visual analogue scale (EQ VAS).

RESULTS

Mean HRQoL at study entry was 69.4 ± 15.6. The presence of agitation, appetite and eating abnormalities, and eyes/ears/nose (ie, sensory impairment) comorbidities were associated with a change in HRQoL over time. Agitation was most strongly associated with HRQoL over time.

CONCLUSIONS

The association of somatic comorbidities and NPS in memory clinic patients with course of HRQoL shows that these should receive more awareness, detection, and monitoring by clinicians.

Assessment of Geriatric Depression Scale's Applicability in Longevous Persons based on Classical Test and Item Response Theory

BACKGROUND

The 15-item short form Geriatric Depression Scale (GDS-15) has been widely used for depression screening in multiple settings. However, few studies have specifically investigated the applicability of GDS-15 in longevous population. The aim of this study is to evaluate the psychometric property and item characteristic of the scale in Chinese community-dwelling longevous persons.

MATERIALS AND METHODS

A total of 838 longevous people participated in this study. The reliability and validity of GDS-15 were analyzed with classical test theory, and the characteristics of each item were analyzed with item response theory using a three-parameters logistic model.

RESULTS

The Cronbach's α coefficient of the scale was 0.776. Spearman correlation coefficients between the GDS-15 score and each item were between 0.274 and 0.667 (P<0.01); the summed GDS-15 score was negatively associated with physical function, self-report health status and subjective well-being. Factors extracted using exploratory factor analysis accounted for 52.63% of the variance and the item loadings were between 0.513 and 0.828. The discrimination of each item ranged from 1.045 to 3.777; the difficulty ranged from -0.972 to 2.006, and the guessing parameter ranged from 0.000 to 0.499. The total information of GDS-15 was 13.645 when the subject's latent trait located at 1.131.

LIMITATION

The sample used is representative of the longevous in rural communities, thus extrapolation to other populations requires further validation.

CONCLUSION

The GDS-15 has good applicability in depression detecting among Chinese longevous persons, especially for the individuals with moderate symptoms. Suggestions were provided on further improving its measurement precision.

Estimating the potential for dementia prevention through modifiable risk factors elimination in the real-world setting: a population-based study

BACKGROUND

Preventing dementia onset is one of the global public health priorities: around 35% of dementia cases could be attributable to modifiable risk factors. These estimates relied on secondary data and did not consider the concurrent effect of non-modifiable factors and death. Here, we aimed to estimate the potential reduction of dementia incidence due to modifiable risk factors elimination, controlling for non-modifiable risk factors and for the competing risk of death.

METHODS

Participants from the InveCe.Ab population-based prospective cohort (Abbiategrasso, Italy) without a baseline dementia diagnosis and attending at least one follow-up visit were included (N = 1100). Participants underwent multidimensional assessment at baseline and after 2, 4, and 8 years, from November 2009 to January 2019. Modifiable risk factors were low education, obesity, hypertension, diabetes, depression, smoking, physical inactivity, hearing loss, loneliness, heart disease, stroke, head injury, and delirium. Non-modifiable risk factors were age, sex, and APOE ε4 genotype. The primary endpoint was dementia diagnosis within the follow-up period (DSM-IV criteria). We performed competing risk regression models to obtain sub-hazard ratio (SHR) for each exposure, with death as competing risk. The exposures associated with dementia were included in a multivariable model to estimate their independent influence on dementia and the corresponding population attributable fraction (PAF).

RESULTS

Within the study period (mean follow-up, 82.3 months), 111 participants developed dementia (10.1%). In the multivariable model, APOE ε4 (SHR = 1.89, 95% CI 1.22-2.92, p = 0.005), diabetes (SHR = 1.56, 95% CI 1.00-2.39, p = 0.043), heart disease (SHR = 1.56, 95% CI 1.03-2.36, p = 0.037), stroke (SHR = 2.31, 95% CI 1.35-3.95, p = 0.002), and delirium (SHR = 8.70, 95% CI 3.26-23.24, p <  0.001) were independently associated with increased dementia risk. In the present cohort, around 40% of dementia cases could be attributable to preventable comorbid diseases.

CONCLUSIONS

APOE ε4, diabetes, heart disease, stroke, and delirium independently increased the risk of late-life dementia, controlling for the competing risk of death. Preventive intervention addressed to these clinical populations could be an effective approach to reduce dementia incidence. Further studies on different population-based cohort are needed to obtain more generalizable findings of the potential of dementia prevention in the real-world setting.

Test-retest reliability and minimal detectable change of the Contextual Memory Test in older adults with and without mild cognitive impairment

BACKGROUND

The ability to detect one's own memory capacity and develop strategies based on daily contexts is important for daily activities. The Contextual Memory Test (CMT) assesses self-awareness, self-efficacy, self-perception/evaluation of performance, recall, and strategy use that are associated with daily contexts, and could be a potentially suitable measurement for assessing memory and meta-memory in older adults with and without cognitive impairment. Nevertheless, the test-retest reliability and minimal detectable change (MDC) remain unknown in these individuals.

OBJECTIVE

The purpose of this study was to examine test-retest reliability and calculate MDC of the CMT in healthy older adults and those with mild cognitive impairment (MCI).

METHODS

Eighty-three participants completed the CMT twice with a one-month interval. Test-retest reliability was examined using intraclass correlation coefficient (ICC) in all seven domains of the CMT and the recognition subtest. The standard error of measurement (SEM) and MDC were calculated. The Bland-Altman analysis was performed to evaluate the degree of agreement between measurements.

RESULTS

The ICC of five domains (self-awareness, self-perception/evaluation of performance, immediate/delayed/total recall) and the recognition subtest were good to excellent (ICC = 0.63-0.94) in healthy and MCI participants and the MDC% were less than 30% The ICC of the other two domains (self-efficacy and total strategy use, TSS) were low (ICC = 0.07-0.59) and the MDC% exceeded 30%. The Bland-Altman analysis showed generally better performance in the 2nd than the 1st measurement in most CMT domains.

CONCLUSIONS

Our results revealed sufficient test-retest reliability and acceptable MDC in most CMT domains in healthy and MCI participants. Only the self-efficacy and TSS domains demonstrated low ICC and large MDC. Possible practice effects were found between repeated measurements. Clinicians should be cautious when evaluating self-efficacy and strategy use using the CMT in older adults. Further improvements are needed for these two domains.

The longitudinal association between depressive symptoms and functional abilities in older patients

OBJECTIVES

To investigate the course of depressive symptoms, and basic and instrumental activities of daily living (collectively described as, (I)ADL functioning) from acute admission until one year post-discharge, the longitudinal association between depressive symptoms and (I)ADL functioning, and to disaggregate between- and within-person effects to examine whether changes in depressive symptoms are associated with changes in (I)ADL functioning.

METHODS

Prospective multicenter cohort of acutely hospitalized patients aged ≥70. Data gathered over a one-year period were assessed using validated measures of depressive symptoms (GDS-15) and physical functioning (Katz-ADL index). A Poisson mixed model analysis was used to examine the association between the courses and a hybrid model was used to disentangle between- and within-subject effects.

RESULTS

The analytic sample included 398 patients (mean age = 79.6 years, SD = 6.6). Results showed an improvement in depressive symptoms and physical functions over time, whereby changes in depressive symptoms were significantly associated with the course of ADL function (rate ratio (RR) = 0.91, p < .001) and IADL function (RR = 0.94, p < .001), even after adjustment for confounding variables. Finally, both between- and within-person effects of depressive symptoms were significantly associated with the course of ADL function (between-person: RR = 0.85, p < .001; within-person: RR = 0.94, p < .001) and IADL function (between-person: RR = 0.87, p < .001; within-person: RR = 0.97, p < .001).

CONCLUSION

The course of depressive symptoms and physical functions improved over time, whereby changes in depressive symptoms were significantly associated with changes in physical functions, both at group and individual level. These changes in (I)ADL functioning lie mostly above the estimated minimally important change for both scales, implying clinically relevant changes.

Comparing patient and informant ratings of depressive symptoms in various stages of Alzheimer's disease

OBJECTIVE

Using a multimethod approach, this study assessed the relationship between patient and informant ratings of depression in Alzheimer's disease (AD) in a manner that better represents the progressive course of AD, and allows for elucidation of specific cognitive domains that may explain changes in respondent agreement.

METHOD

Case data (N = 16,297) were provided by the National Alzheimer's Coordinating Center (NACC). A series of contingency analyses were performed to assess the relationship between patient and informant agreement across levels of impairment in individuals with AD. Patients and informants were placed into groups (i.e., not impaired, mild impairment, moderate impairment, severe impairment) based on patients' performance on multiple indicators of global cognitive functioning, as well as measures of attention, working memory, processing speed, executive functioning, language, and episodic learning and memory.

RESULTS

Across measures, greater impairment was significantly (p < .001) associated with decreases in patient-informant congruence and increases in rates of patients denying depression when informants endorsed observing features of the same. These inconsistencies were most pronounced in the mildest stages of impairment. For a subset of the sample, rates of patients reporting depressive symptoms when informants denied observing the same also increased alongside worsening impairment. Incremental impairment in episodic learning (χ² = 805.25) and memory (χ² = 856.94) performance were most closely associated with decreases in respondent agreement. Patient-informant relationship type did not appear to mediate the response patterns observed.

CONCLUSIONS

Mild impairment in AD patients, particularly in episodic learning and memory functioning, is significantly associated with decreases in patient-informant agreement regarding the presence of depressive symptoms. These results suggest that even at the earliest stages of AD informant reports should be used to corroborate patients' reporting. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Longitudinal relationships among depressive symptoms and three types of memory self-report in cognitively intact older adults

OBJECTIVES

The current study examined whether self-reported memory problems among cognitively intact older adults changed concurrently with, preceded, or followed depressive symptoms over time.

DESIGN

Data were collected annually via in-person comprehensive medical and neuropsychological examinations as part of the Einstein Aging Study.

SETTING

Community-dwelling older adults in an urban, multi-ethnic area of New York City were interviewed.

PARTICIPANTS

The current study included a total of 1,162 older adults (Mage = 77.65, SD = 5.03, 63.39% female; 74.12% White). Data were utilized from up to 11 annual waves per participant.

MEASUREMENTS

Multilevel modeling tested concurrent and lagged associations between three types of memory self-report (frequency of memory problems, perceived one-year decline, and perceived ten-year decline) and depressive symptoms.

RESULTS

Results showed that self-reported frequency of memory problems covaried with depressive symptoms only in participants who were older at baseline. Changes in perceived one-year and ten-year memory decline were related to changes in depressive symptoms across all ages. Depressive symptoms increased the likelihood of perceived ten-year memory decline the next year; however, perceived ten-year memory decline did not predict future depressive symptoms. Additionally, no significant temporal relationship was observed between depressive symptoms and self-reported frequency of memory problems or perceived one-year memory decline.

CONCLUSION

Our findings highlight the importance of testing the unique associations of different types of self-reported memory problems with depressive symptoms.

Association of serum adiponectin levels and body mass index with worsening depressive symptoms in elderly individuals: a 10-year longitudinal study

Objectives: Data regarding the association between adiponectin levels and body mass index (BMI) and long-term changes in depressive symptoms are limited and inconsistent. Thus, we investigated whether circulating adiponectin levels and BMI were independently and combinedly correlated to longitudinal changes in depressive symptoms.Methods: This prospective cohort study evaluated 269 elderly Japanese individuals aged ≥70 years who participated in the Tsurugaya Project conducted between 2002 and 2012. A short form of the Geriatric Depression Scale (GDS) was used to assess depressive status. Serum adiponectin levels were measured using an enzyme-linked immunosorbent assay or a latex particle-enhanced turbidimetric immunoassay. BMI was calculated as body weight (kg)/height (m²).Results: Multiple linear regression analysis revealed that baseline serum adiponectin levels were positively associated with changes in GDS scores (β = 0.14, P = 0.035). However, no association was observed after adjusting for BMI (β = 0.09, P = 0.185). Low BMI was associated with increased GDS scores at the 10-year follow-up (β = -0.14, P = 0.033). Participants with a combination of high adiponectin levels and low BMI had a 3.3-fold higher risk of worsening depressive symptoms than those with low adiponectin levels and high BMI (odds ratio: 3.35, 95% confidence interval: 1.60-7.00; P = 0.001).Conclusions: This longitudinal study indicated that high serum adiponectin levels and low BMI were both associated with worsening depressive symptoms among older Japanese individuals. Furthermore, the combination of high adiponectin levels and low BMI was associated with worsening depressive symptoms.

Latent structure of the Centre for Epidemiologic Studies Depression Scale (CES-D) in older adult populations: a systematic review

Objective: The Center for Epidemiologic Studies Depression Scale (CES-D) is a 20-item, self-report metric intended to measure depression. Despite being one of the most popular depression scales, the psychometric properties, specifically the underlying factor structure of the scale, have come under scrutiny. The latent structure of a scale is a key indicator of its construct validity, i.e. the degree to which the intended variable is captured. To date, a comprehensive review of the latent structure of the CES-D in older adult populations (≥65 years old) has not been conducted. We aimed to examine the latent structure of the CES-D in samples of older adults to assess its ability to capture depressive symptoms.Methods: A systematic review across Scopus, Web of Science, and PsycINFO databases was conducted. Original studies conducting latent variable analysis of the 20-item CES-D in samples aged ≥65 years old were included.Results: Included studies (n = 6) were primarily conducted with community-dwelling older adults in the United States. Studies that conducted exploratory and confirmatory factor analysis (n = 2) revealed two latent factors, whereas those conducting confirmatory factor analysis of previously identified structures (n = 4) revealed four-factor structures in line with the original four-factor structure.Conclusions: A general alignment with the original four-factor structure of the CES-D provides tentative support for continued use amongst older adults; however, further research is required to provide conclusive evidence for these psychometric properties.

Social media usage, social support, intergenerational relationships, and depressive symptoms among older adults

Many older adults are unable to use social media, which may affect their social support and intergenerational relationships and cause depression. To examine this impact on older Taiwanese adults, we used purposive sampling, a cross-sectional, correlational study design, and a structured questionnaire to collect data on participants' characteristics, social media usage, social support, intergenerational relationships, and depressive symptoms. We studied 153 older adults (aged 60 years and above) and found higher levels of depressive symptoms among participants who took medication, did not exercise regularly or participate in leisure activities, experienced poor health and sleep quality, and had poorer functional ability compared to their counterparts. Depressive symptoms were significantly associated with social media usage, social support, and intergenerational relationships. We recommend considering risk factors and offsetting depressive symptoms by promoting the use of social media and regular exercise to increase social interactions, social support, and intergenerational relationships among older adults.

Effectiveness of peer counseling, social engagement, and combination interventions in improving depressive symptoms of community-dwelling Filipino senior citizens

INTRODUCTION

Little is known about community-based interventions for geriatric depression in low-resource settings. This study assessed the effectiveness of 3-month-duration interventions with peer counseling, social engagement, and combination vs. control in improving depressive symptoms of community-dwelling Filipino senior citizens.

METHODS

We conducted an open (non-blinded), non-randomized trial of senior citizens at risk for depression. Three different 3-month interventions included peer counseling (n = 65), social engagement (n = 66), and combination (n = 65) were compared with the control group (n = 68). We assessed geriatric depression, psychological resilience, perceived social support, loneliness, and working alliance scores at baseline and three months after the intervention. This trial was registered with ClinicalTrials.gov, identifier: NCT03989284.

RESULTS

Geriatric depression score over three months significantly improved in all intervention groups (control as reference). Significant improvements were also seen in psychological resilience and social support. Not all interventions, however, significantly improved the loneliness score. The combination group showed the largest effect of improving depressive symptoms (d = -1.33) whereas the social engagement group showed the largest effect of improving psychological resilience (d = 1.40), perceived social support (d = 1.07), and loneliness (d = -0.36) among senior citizens.

CONCLUSION

At the community level, peer counseling, social engagement, and combination interventions were effective in improving depressive symptoms, psychological resilience, and social support among Filipino senior citizens. This study shows that it is feasible to identify senior citizens at risk for depression in the community and intervene effectively to improve their mental health. Further studies are required to target loneliness and investigate the long-term benefits of the interventions.

Comparative effectiveness of three exercise types to treat clinical depression in older adults: A systematic review and network meta-analysis of randomised controlled trials

BACKGROUND

Few studies have directly compared the effects of different exercise therapies on clinical depression in older adults. Thus, we conducted a systematic review and network meta-analysis of current evidence from randomised controlled trials (RCTs) to compare the effectiveness of three major exercise types (aerobic, resistance, and mind-body exercise) in clinically depressed older adults.

METHODS

We followed PRISMA-NMA guidelines and searched databases for eligible RCTs (inception - September 12^th, 2019). RCTs were eligible if they included clinically depressed adults aged >65 years, implemented one or more exercise therapy arms using aerobic, resistance, or mind-body exercise, and assessed depressive symptoms at baseline and follow-up using a validated clinical questionnaire.

RESULTS

A network meta-analysis was performed on 15 eligible RCTs comprising 596 participants (321 treatment and 275 controls), including aerobic (n = 6), resistance (n = 5), and mind-body (n = 4) exercise trials. Compared with controls, mind-body exercise showed the largest improvement on depressive symptoms (g = -0.87 to -1.38), followed by aerobic exercise (g = -0.51 to -1.02), and resistance exercise (g = -0.41 to -0.92). Notably, there were no statistically significant differences between exercise types: aerobic versus resistance (g = -0.10, PrI = -2.23, 2.03), mind-body versus aerobic (g = -0.36, PrI = -2.69, 1.97), or mind-body versus resistance (g = -0.46, PrI = -2.75, 1.83).

CONCLUSIONS

These findings should guide optimal exercise prescription for allied health professionals and stakeholders in clinical geriatrics. Notably, clinically depressed older adults may be encouraged to self-select their preferred exercise type in order to achieve therapeutic benefit on symptoms of depression. In coalition with high levels of compliance, these data provide encouraging evidence for the antidepressant effect of either aerobic, resistance, or mind-body exercise as effective treatment adjucts for older adults presenting with clinical depression.

Diagnostic accuracy of various forms of geriatric depression scale for screening of depression among older adults: Systematic review and meta-analysis

OBJECTIVES

Depression is under-reported and under-identified by the healthcare professionals. Geriatric depression scale (GDS) is one of the most commonly used instruments for screening the older adults for depression. The current review was done to determine the diagnostic accuracy of various forms of GDS for screening of depression among older adults.

METHODS

We conducted systematic search in various databases like Medline, Cochrane library, Sciencedirect and Google Scholar from inception till May 2019. Quality of trials was assessed by Quality Assessment of Diagnostic Accuracy Studies-2 tool. We performed bivariate meta-analysis to obtain the pooled sensitivity, specificity, positive, negative likelihood ratio and diagnostic odds ratio for each of the GDS forms.

RESULTS

Totally 53 studies with 17,018 participants were included in the review. We found the pooled sensitivity and specificity of GDS 30 to be 82 % and 76 % with near higher diagnostic accuracy (AUC = 0.85). GDS 15 had pooled sensitivity and specificity of 86 % and 79 % with higher diagnostic accuracy (AUC = 0.90). GDS 10 had pooled sensitivity and specificity of 87 % and 75 % with AUC = 0.83. Our study found GDS 4 to have sensitivity of 74 % with specificity of 71 %. All the four forms of GDS belonged to right lower quadrant of LR scatter-gram indicating neither confirmation nor exclusion.

CONCLUSION

Current study found that all the forms of GDS are highly useful for detecting depression among elderly with higher sensitivity and specificity. The diagnostic performance was much better for shorter forms of GDS such as GDS 15 and GDS 10 when compared to GDS 30.

Sedentary behavior as a potential risk factor for depression among 70-year-olds

BACKGROUND

Sedentary behavior has previously been associated with the risk of depression. In addition, older adults have been proven to be more sedentary and more depressed than other age groups. However, studies using objective measures of sedentary behavior and taking physical activity into account are lacking. Thus, the purpose of this population-based study was to examine how total sedentary time and length of sedentary bouts were associated with the risk of depression among 70-year-olds.

METHODS

The present study used data from the Healthy Ageing Initiative (n = 3,633), an ongoing cross-sectional research project in Umeå, Sweden. Sedentary behavior was measured objectively with the ActiGraph GT3X+ accelerometer, and depression was measured with the Geriatric Depression Scale. Several covariates, including physical activity, were included in logistic regression analyses.

RESULTS

Results from two hierarchical logistic regression models showed that a greater percentage of the day spent sedentary [odds ratio (OR) = 1.031, p = 0.010] and longer average length of sedentary bouts (OR = 1.116, p = 0.045) increased the risk of depression.

LIMITATIONS

Limitations include of possible underrepresentation of severely depressed participants, and possible observer effects.

CONCLUSIONS

The present study verified the relationship between sedentary behavior and depression and provides new information about the risks associated with increased length of sedentary bouts.  These findings may be important to consider in the development of future recommendations for the prevention of depression among older adults.

Evaluating depression in cognitively healthy elderly people by using Mini-Mental State Examination

AIM

We examined a method for evaluating depression with the Mini-Mental State Examination in cognitively healthy elderly people and employed the projective perspective.

METHODS

In MMSE three groups-normal, depressed tendency, and depressed-completed the Mini-Mental State Examination (MMSE) and a Japanese version of the 15-item Geriatric Depression Scale. The Mini-Mental State Examination evaluated individuals' writing based on a sentence, the number of written words, and sentence content; it also assessed their copying of drawn figures.

RESULTS

In the depressed group, the proportion corresponding to the characteristics of (i) to (iii) was higher than in the other two groups: (i) the calculation score was 0 or 1; (ii) subjects scored above the median in sentence writing relative to similar subjects with the same language and clinical setting; and (iii) subjects expressed feelings in their writing. One point was given for each characteristic, and we calculated the sum. Depressed subjects had a score ≥2.

CONCLUSIONS

This evaluation method can differentiate depressed subjects with high accuracy (sensitivity: 77.8%, specificity: 76.4%) without placing an extra burden on the subjects.

A multicomponent exercise intervention to improve physical functioning, cognition and psychosocial well-being in elderly nursing home residents: a study protocol of a randomized controlled trial in the PROCARE (prevention and occupational health in long-term care) project

BACKGROUND

Older adults, who are living in nursing homes that provide a high level of long-term nursing care, are characterized by multimorbidity and a high prevalence of dependency in activities of daily living. Results of recent studies indicate positive effects of structured exercise programs during long-term care for physical functioning, cognition, and psychosocial well-being. However, for frail elderly the evidence remains inconsistent. There are no evidence-based guidelines for exercises for nursing home residents that consider their individual deficits and capacities. Therefore, high-quality studies are required to examine the efficacy of exercise interventions for this multimorbid target group. The purpose of this study is to determine the feasibility and efficacy of a multicomponent exercise intervention for nursing home residents that aims to improve physical and cognitive functioning as well as quality of life.

METHODS

A two-arm single-blinded multicenter randomized controlled trial will be conducted, including 48 nursing homes in eight regions of Germany with an estimated sample size of 1120 individuals. Participants will be randomly assigned to either a training or a waiting time control group. For a period of 16 weeks the training group will meet twice a week for group-based sessions (45-60 min each), which will contain exercises to improve physical functioning (strength, endurance, balance, flexibility) and cognitive-motor skills (dual-task). The intervention is organized as a progressive challenge which is successively adapted to the residents' capacities. Physical functioning, cognitive performance, and quality of life will be assessed in both study groups at baseline (pre-test), after 16-weeks (post-treatment), and after 32-weeks (retention test, intervention group only).

DISCUSSION

This study will provide information about the efficacy of a multicomponent exercise program in nursing homes (performance, recruitment). Results from this trial will contribute to the evidence of multicomponent exercises, which specifically focus on cognitive-motor approaches in the maintenance of mental and physical functioning. In addition, it will help to encourage older adults to actively engage in social life. Furthermore, the findings will lead to recommendations for health promotion interventions for frail nursing home residents.

TRIAL REGISTRATION

The trial was prospectively registered at DRKS.de with the registration number DRKS00014957 on October 9, 2018.

Caregiver burden: An increasing problem related to an aging cancer population

This prospective cohort study identified risk factors for the development of caregiver burden and included older cancer survivors, middle-aged cancer survivors, older patients without cancer and their caregivers. Overall, more than 16 per cent of caregivers experienced high-to-severe burden at baseline. This proportion remained stable after 1 and 3 years. Caregivers who experienced increased caregiver burden at baseline were at higher risk maintaining their caregiver burden over the following years. Caregiver burden was not related to the cancer diagnosis but rather to the baseline psychosocial well-being of both the caregiver and patient and the physical condition of the patient.

Leadership and Peer Counseling Program: Evaluation of Training and Its Impact on Filipino Senior Peer Counselors

Senior volunteers represented a significant, mostly untapped lay resource of informal social care. In this study, we evaluated the effectiveness of the training program on improving senior volunteers' competency toward peer counseling, and explored its impact on their well-being after three months of the program implementation. We conducted a pre- and post-intervention analysis among 60 senior volunteers aged 60-82 years. They participated in 40 h of training and performed weekly peer counseling home visits for three months. We evaluated the program using survey questionnaires, trainer observation and debriefing, and focus group discussions. After the training, peer counselors showed a significant improvement (p < 0.001) in knowledge (17.1 versus 22.3) and skills (17.0 versus 17.9). All of them met the minimum required passing level of 70% for the knowledge test, and their overall performance was satisfactory as rated by two independent trainers. After three months, peer counselors showed a significant improvement (p < 0.001) in their subjective well-being (d = 0.69) and depressive symptoms (d = -0.67). Filipino senior volunteers could be trained to serve as peer counselors in their communities. This program improved their competency and well-being. Future research is warranted to determine whether the provision of counseling by them will affect the health outcomes of the target population.

Physical Function, Frailty, Cognition, Depression, and Quality of Life in Hospitalized Adults ≥60 Years With Acute Decompensated Heart Failure With Preserved Versus Reduced Ejection Fraction

BACKGROUND

Older hospitalized acute decompensated heart failure (HF) patients have persistently poor outcomes and delayed recovery regardless of ejection fraction (EF). We hypothesized that impairments in physical function, frailty, cognition, mood, and quality of life (QoL) potentially contributing to poor clinical outcomes would be similarly severe in acute decompensated HF patients ≥60 years of age with preserved versus reduced EF (HFpEF and HFrEF).

METHODS AND RESULTS

In 202 consecutive older (≥60 years) hospitalized acute decompensated HF patients in a multicenter trial, we prospectively performed at baseline: short physical performance battery, 6-minute walk distance, frailty assessment, Geriatric Depression Scale, Montreal Cognitive Assessment, and QoL assessments. Older acute decompensated HFpEF (EF ≥45%, n=96) and HFrEF (EF <45%, n=106) patients had similar impairments in all physical function measures (short physical performance battery [5.9±0.3 versus 6.2±0.2]; 6-minute walk distance [184±10 versus 186±9 m]; and gait speed [0.60±0.02 versus 0.61±0.02 m/s]) and rates of frailty (55% versus 52%; P=0.70) and cognitive impairment (77% versus 81%; P=0.56) when adjusted for differences in sex, body mass index, and comorbidities. However, depression and QoL were consistently worse in HFpEF versus HFrEF. Depression was usually unrecognized clinically with 38% having Geriatric Depression Scale ≥5 and no documented history of depression.

CONCLUSIONS

Patients ≥60 years hospitalized with acute decompensated HF patients have broad, marked impairments in physical function and high rates of frailty and impaired cognition: these impairments are similar in HFpEF versus HFrEF. Further, depression was common and QoL was reduced, and both were worse in HFpEF than HFrEF. Depression was usually unrecognized clinically. These findings suggest opportunities for novel interventions to improve these important patient-centered outcomes.

A Mixed-Methods Evaluation of a Nurse-Led Community-Based Health Home for Ethnically Diverse Older Adults With Multimorbidity in the Adult Day Health Setting

Multimorbidity affects 75% of older adults (aged 65 years and older) in the United States and increases risk of poor medical outcomes, especially among the poor and underserved. The creation of a Medicaid option allowing states to establish health homes under the Affordable Care Act was intended to enhance coordinated care for Medicaid beneficiaries with multimorbidity. The Community-Based Health Home (CBHH) model uses the infrastructure of the Adult Day Health Center (ADHC) to serve as a health home to improve outcomes for medically complex vulnerable adults. Between 2017 and 2018, we used a sequential explanatory mixed-methods approach to (a) quantitatively examine changes in depression, fall risk, loneliness, cognitive function, nutritional risk, pain classification, and health care utilization over the course of 12 months in the program and (b) qualitatively explore the perspectives of key stakeholders (registered nurse navigators, participants, ADHC administrators, and caregivers) to identify the most effective components of CBHH. Using data integration techniques, we identified components of CBHH that were most likely driving outcomes. After 12 months in CBHH, our racially diverse sample (N = 126), experienced statistically significant (p < .05) reductions in loneliness, depression, nutritional risk, poorly controlled pain, and emergency department utilization. Stakeholders who were interviewed (n = 40) attributed positive changes to early clinical intervention by the registered nurse navigators, communication with providers across settings, and a focus on social determinants of health, in conjunction with social stimulation and engagement provided by the ADHC. CBHH positions the ADHC as the locus of an effective health home site and is associated with favorable results. CBHH also demonstrates the unique capacity and skill of registered nurses in integrating health and social services across community settings. Continued exploration of CBHH among diverse populations with multimorbidity is warranted.

Effects of the falls and fractures clinic as an integrated multidisciplinary model of care in Australia: a pre-post study

OBJECTIVES

Traditionally, the approach to fracture prevention has focused on increasing bone mineral density while typically lacking a combined clinical approach to falls prevention and vice versa. To resolve this gap, we implemented and evaluated a novel combined model of care to the assessment and prevention of osteoporosis and falls in the outpatients setting.

SETTING

Falls and Fractures Clinic (FFC) at Nepean Hospital (Penrith, NSW, Australia).

PARTICIPANTS

Pre-effects and posteffects assessment of 106 community-dwelling older patients referred from the community.

PRIMARY AND SECONDARY OUTCOME MEASURES

Previous falls and fractures were recorded. Clinical, functional and paraclinical evaluations were performed. A comprehensive multidisciplinary care plan was then tailored based on the presence of risk factors. Six-month follow-ups were performed assessing the incidence of falls and fractures, change in risk factors for falls and level of risk, with the recommended plan.

RESULTS

We report that 97% of patients had a fall in the preceding 6 months, 47.6% of whom experienced a fracture from the fall. Furthermore, 64% of patients had a marked risk for falling by Physiological Profile Assessment (PPA), 90% had intermediate-high 10-year probability of fracture according to FRAX and 78% had sarcopenia. At 6-month follow-up, we observed more than an 80% reduction in falls and recurrent falls, and 50% reduction in fractures. In addition, 65% of patients had reduced PPA and a 57% reduction in 10-year fracture probability.

CONCLUSIONS

In conclusion, we suggest that a multidisciplinary FFC can provide substantial reductions in falls and fractures for high-risk older people, even over a relatively short 6-month time period. The current model of service provision via traditional falls clinics could be significantly improved by encompassing fracture prevention within the multifactorial approach to interventions.

The brief Dimensional Apathy Scale: A short clinical assessment of apathy

Objective: Apathy is a prominent syndrome across neurodegenerative diseases. The Dimensional Apathy Scale (DAS) assesses three apathy subtypes-executive, emotional, and initiation-and is sensitive and valid in amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD), and Parkinson's disease. This study describes the development of the brief DAS (b-DAS), which will enable apathy to be swiftly detected in the clinic.Method: 102 ALS and 102 AD patients' previously collected data were used. Mokken analyses were performed on item-level data of each informant/carer-rated DAS subscale (executive, emotional, and initiation) for the initial scale reduction. Item-total correlational analyses against standard apathy (convergent validity criteria) and depression (divergent validity criteria) measures and qualitative examination of items aided final item selection. Receiver operating curve analysis determined optimal cutoffs for the reduced subscales.Results: Mokken analyses suggested unidimensionality of each DAS subscale. Three items were removed that failed to satisfy monotone homogeneity model requirements, three items were removed due to validity criteria not being met, and six items were removed due to a combination of lower item scalability and item-total correlations. Item-theme examination further reduced the b-DAS to nine items, three per subscale, with a supplemental awareness deficit assessment being added. Sensitivity- and specificity-based optimal cutoffs were calculated for each b-DAS subscale.Conclusions: This study presents the b-DAS, an informant/carer-based robust yet short multidimensional apathy instrument with good convergent and divergent validity, with recommended clinical cutoffs. The b-DAS is appropriate for use in the clinic and for research to quickly and comprehensively screen for apathy subtype impairments.

Hopelessness and Other Depressive Symptoms in Adults 70 Years and Older as Predictors of All-Cause Mortality Within 3 Months After Acute Hospitalization: The Hospital-ADL Study

OBJECTIVE

Depression among older adults predicts mortality after acute hospitalization. Depression is highly heterogeneous in its presentation of symptoms, whereas individual symptoms may differ in predictive value. This study aimed to investigate the prevalence of individual cognitive-affective depressive symptoms during acute hospitalization and investigate the predictive value of both overall and individual cognitive-affective depressive symptoms for mortality between admission up to 3-month postdischarge among older patients.

METHODS

A prospective multicenter cohort study enrolled 401 acutely hospitalized patients 70 years and older (Hospitalization-Associated Disability and impact on daily Life Study). The predictive value of depressive symptoms, assessed using the Geriatric Depression Scale 15, during acute hospitalization on mortality was analyzed with multiple logistic regression.

RESULTS

The analytic sample included 398 patients (M (SD) = 79.6 (6.6) years; 51% men). Results showed that 9.3% of participants died within 3 months, with symptoms of apathy being most frequently reported. The depression total score during hospitalization was associated with increased mortality risk (admission: odds ratio [OR] = 1.2, 95% confidence interval [CI] = 1.2-1.3; discharge: OR = 1.2, 95% CI = 1.2-1.4). Stepwise multiple logistic regression analyses yielded the finding that feelings of hopelessness during acute hospitalization were a strong unique predictor of mortality (admission: OR = 3.6, 95% CI = 1.8-7.4; discharge: OR = 5.7, 95% CI = 2.5-13.1). These associations were robust to adjustment for demographic factors, somatic symptoms, and medical comorbidities.

CONCLUSIONS

Symptoms of apathy were most frequently reported in response to acute hospitalization. However, feelings of hopelessness about their situation were the strongest cognitive-affective predictor of mortality. These results imply that this item is important in identifying patients who are in the last phase of their lives and for whom palliative care may be important.
