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

Depression is associated with worse health-related quality of life, lower physical activity levels, and inadequate sleep quality in a Greek elderly population

The present study is a cross-sectional study that aimed to investigate the potential associations between depression status, health-related quality of life, physical activity levels and sleep quality in a representative Greek elderly population. Three thousand four hundred five (3405) men and women over 65 years old from 14 different Greek regions were enrolled. Geriatric Depression Scale (GDS) was used to assess depression status, Health-Related Quality of Life (HRQOL) was evaluated using Short Form Health Survey, physical activity levels were assessed via the International Physical Activity Questionnaire (IPAQ) and sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). A high prevalence of depression and an increased incidence of poor quality of life, low physical activity levels and inadequate sleep quality among the elderly population were recorded. Depression status was independently associated with worse quality of life, poor physical activity, inadequate sleep quality, female gender, BMI and living alone after adjustment for potential confounding factors. Elderly age, low muscle mass, educational and financial status were also identified as indicators of depression; however, their impact on depression status was considerably attenuated after adjusting for confounding factors. In conclusion, depression was associated with worse health-related quality of life, poor physical activity and inadequate sleep quality in a Greek elderly population. Future randomized control trials should be performed to confirm the findings of this cross-sectional study.

Assessment of validity and comparison of two Spanish versions of the Geriatric Depression Scale

Introduction

The Geriatric Depression Scale is an instrument used to identify depression in people of an older age. The original English version of this scale has been translated into Spanish (GDS-VE); two shorter versions of 5- (GDS-5) and 15-items (GDS-15) have been developed.

Aim of the study

To assess the validity and compare the 5- and 15-item Spanish versions of the GDS among the Spanish population.

Materials and methods

573 Galicia residents aged >50 years participated in this study. The following instruments were applied: the 19-item Control, Autonomy, Self-Realization and Pleasure scale, the Subjective Memory Complaints Questionnaire, the Mini-Mental State Examination test, the GDS-5, and the GDS-15.

Results

We found differences in total score between GDS-5 and GDS-15 regarding the variable sex. Internal reliability for GDS-5 and GDS-15 was 0.495 and 0.715, respectively. Sensitivity and specificity for GDS-5 - with a cut-off value of 1 - was 0.517 and 0.650, respectively; for GDS-15 - with a cut-off value of 3 points - sensitivity was 0.755 and specificity 0.668. GDS-5 has a ROC curve of 0.617 and GDS-15 of 0.764.

Conclusion

GDS-15, and to a greater extent GDS-5, should be revised or even reformulated to improve their diagnostic usefulness by choosing higher discriminative ability items or even include new items with greater sensitivity that consider currently prevailing psychosocial factors.

Psychosocial needs of older patients with metastatic breast cancer treated at community centers

INTRODUCTION

Psychosocial status contributes to overall quality of life (QOL) for patients with cancer as psychosocial distress is commonly seen in this population. We sought to describe the psychosocial needs of older adults with metastatic breast cancer (MBC) treated in the community. We evaluated the correlation between the patient's psychosocial status and the presence of other geriatric abnormalities in this patient population.

MATERIALS AND METHODS

This is a secondary analysis of a completed study evaluating older adults (≥65 years) with MBC treated at community practices who received a geriatric assessment (GA). This analysis evaluated psychosocial factors collected during GA, including depression assessed by Geriatric Depression Scale (GDS), perceived social support (SS) assessed by Medical Outcomes Study Social Support Survey (MOS), and objective social supportassessed by demographic variables (living situation and marital status). Perceived SS was further subdivided into tangible social support (TSS) and emotional social support (ESS). Kruskal-Wallis tests, Wilcoxon tests, and Spearman's correlations were used to assess the relationship between psychosocial factors, patient characteristics, and geriatric abnormalities.

RESULTS

One hundred older patients with MBC were enrolled and completed GA with a median age of 73 years (65-90). Almost half of the participants (47%) were either single, divorced, or widowed and 38% lived alone, demonstrating a significant number of patients with objective social support deficits. Patients with HER2+ or triple negative MBC had lower overall SS scores compared to patients with ER/PR+ or HER2- MBC (p = 0.033). Patients on fourth line of therapy were more likely to screen positive for depression compared to patients on earlier lines of therapy (p = 0.047). About half (51%) of the patients indicated at least one SS deficit on the MOS. A higher GDS and lower MOS score correlated with greater total GA abnormalities (p = 0.016). Evidence of depression correlated with poor functional status, decreased cognition, and a high number of co-morbidities (p < 0.005). Abnormalities in functional status, cognition, and high GDS are associated with lower ESS (p = 0.025,0.031,0.006 respectively).

DISCUSSION

Psychosocial deficits are common among older adults with MBC treated in the community and are associated with the presence of other geriatric abnormalities. These deficits require a thorough evaluation and management to optimize treatment outcomes.

Increasing Identification and Follow-Up of Older Adult Depression in Primary Care

INTRODUCTION

Depression is a common mental health disorder faced by older adults that can go undetected and untreated. It was determined that the project site was not screening for depression among their older patient population. Aims: The purpose of this quality improvement project was to determine if the implementation of the Geriatric Depression Scale-15 (GDS-15) would impact the identification of risk factors for depression and follow-up among adults 65 and older.

METHODS

Implementation started in June 2021 in a primary care office in Southern California. Data was collected for this project over a total of 8 weeks. This project was a quality improvement project designed to implement routine depression screening among older adult patients using the GDS-15. Depressive symptoms were identified, and follow-up and treatment for depression in primary care was initiated if indicated by GDS-15 scores. Data were obtained from the project site's electronic medical record on a total sample size of 443 patients (n = 252 in the comparison group and n = 191 in the implementation group).

RESULTS

A chi-square test indicated a clinical and statistically significant improvement in the identification rate of depression, X2 (1, N = 443) = 49.76, P < .0001; and follow-up rate X2 (1, N = 70) = 23.94, P < .0001. Clinical significance was found with an increase in the identification of depression and follow-up of older adults in primary care. Demographic variables were also compared for the QI intervention group patients according to those who scored <5 (n = 134) and patients who scored 5 or greater on the GDS-15 (n = 57) again using chi-square tests. The results showed significant differences between gender (P = .016) and primary diagnosis (P = .006).

CONCLUSIONS

Findings of this project suggest all older adults should receive a depression screening routinely in primary care to increase the recognition of depression as well as follow-up and treatment.

Genetic and environmental influences on fruit and vegetable consumption and depression in older adults

BACKGROUND

Prior work suggests that higher fruit and vegetable consumption may protect against depression in older adults. Better understanding of the influence of genetic and environmental factors on fruit and vegetable intakes may lead to the design of more effective dietary strategies to increase intakes. In turn this may reduce the occurrence of depression in older adults.

OBJECTIVES

The primary aim of this study is to estimate the genetic and environmental influences on the consumption of fruit and vegetables in older adults. The secondary aim is an exploratory analysis into possible shared genetic influences on fruit and vegetable intakes and depression.

METHODS

Analysis of observational data from 374 twins (67.1% female; 208 monozygotic (MZ); 166 dizygotic (DZ)) aged ≥ 65 years drawn from the Older Australian Twins Study. Dietary data were obtained using a validated food frequency questionnaire and depressive symptoms were measured using the 15-item short form Geriatric Depression Scale. The contribution of genetic and environmental influences on fruit and vegetable intake were estimated by comparing MZ and DZ twin intakes using structural equation modelling. A tri-variate twin model was used to estimate the genetic and environmental correlation between total fruit and vegetable intakes and depression.

RESULTS

In this study, vegetable intake was moderately influenced by genetics (0.39 95%CI 0.22, 0.54). Heritability was highest for brassica vegetables (0.40 95%CI 0.24, 0.54). Overall fruit intake was not significantly heritable. No significant genetic correlations were detected between fruit and vegetable intake and depressive symptoms.

CONCLUSIONS

Vegetable consumption, particularly bitter tasting brassica vegetables, was significantly influenced by genetics, although environmental influences were also apparent. Consumption of fruit was only influenced by the environment, with no genetic influence detected, suggesting strategies targeting the food environment may be particularly effective for encouraging fruit consumption.

How much time of sedentary behavior is associated with depressive symptoms in community-dwelling older adults in southern Brazil?

AIMS

Identify sedentary behavior (SB) cut-off points to screen for depressive symptoms in older adults and verify the association between these conditions.

METHODS

A cross-sectional survey of 308 community-dwelling older adults was conducted. The outcome was the presence of depressive symptoms (≥6 points on the Geriatric Depression Scale-15). The exposure was SB using the self-reported time on a weekday and weekend (International Physical Activity Questionnaire). The cut-off points for SB categorization were determined by the receiver operating characteristic curve and multivariate logistic regression to verify the association.

RESULTS

Older adults who spent ≥4.5 hours/day in SB (sensitivity = 48.8%; specificity = 67.8%) were 1.81 times more likely (95%CI: 1.03;3.15) to have depressive symptoms compared to those who stayed for shorter periods.

CONCLUSIONS

There was an association between SB and depressive symptoms; therefore, older adults must have SB <4.5 hours/day to reduce the chances of developing depressive symptoms.

Prevalence study of mental disorders in an Italian region. Preliminary report

BACKGROUND

Mental disorders are a major public health problem. However, over the last few years, there have been few studies aimed at evaluating their diffusion. Therefore, this study aimed at evaluating: the prevalence of the most frequent psychiatric disorders in the general population residing in Tuscany using a clinical scale administered by trainee in psychiatry.

METHODS

The study was carried out on a representative sample of the general population aged > 18 years, randomly extracted from the register of patients in the Tuscany region, adopting a proportional sampling method stratified by gender, age group and Local Health Units (LHU). Each person was contacted by letter followed by a phone call from an operator who makes an appointment with the trainee in psychiatry. The diagnostic interview conducted was the Mini-International Neuropsychiatric Interview (MINI). Point and lifetime prevalence by gender and age group were calculated. Differences and associations were considered statistically significant if their p-values were less than 0.05.

RESULTS

Of the 408 people involved, 390 people were enrolled (of which 52.6% female). The 28.5% of the sample had been affected by a psychiatric disorder during their lifetime. In their lifetime, the most represented psychiatric disorders were major depressive episode (20.4%), major depressive disorder (17.0%) and panic disorder (10.3%), more frequent in the female than the male group. Current conditions were predominantly major depressive episode (3.1%) and agoraphobia (2.8%). A 5.9% rate of current suicidal ideation was also found.

CONCLUSIONS

In the general population, 28.5% of people reported a psychiatric disorder during their lifetime. This prevalence is considerably higher than that reported in a previous study carried out in central Italy.

Prevalence and Family Determinants of Geriatric Depression Among Elderly People in Elderly Support Groups in Rwanda

Background

The 1994 Tutsi genocide in Rwanda significantly impacted family structure, with many people growing old alone and lacking social bonds and connections with family members. However, little is known about the contribution of the family environment to geriatric depression which was highlighted by WHO as a psychological problem with a 10% to 20% prevalence rate among the elderly worldwide. This study aims to investigate geriatric depression and associated family determinants among the elderly in Rwanda.

Methods

With a community-based cross-sectional study design, we assessed geriatric depression (GD), quality-of-life enjoyment and satisfaction (QLES), family support (FS), loneliness, neglect, and attitude toward grief in a convenience sample of 107 participants (M=72.32, SD=8.79) aged between 60 and 95 years who were recruited from three groups of elderly people supported by the NSINDAGIZA organization in Rwanda. SPSS (version 24) was used for statistical data analysis; differences across various sociodemographic variables were tested for significance by an independent t-test; the relationship between study variables was tested by Pearson correlation analysis; and multiple regression analysis was performed to model the contribution of independent variables to dependent variables.

Results

A total of 64.5% of the elderly scored above the threshold of the normal range of geriatric depression (SDS>49), with higher symptoms in women than in men. Multiple regression analysis indicated that family support and quality-of-life enjoyment and satisfaction were contributors to geriatric depression in the participants.

Conclusion

Geriatric depression was relatively common in our participants. It is associated with the quality of life and family support received. Hence, adequate family-based interventions are needed to improve the well-being of geriatric people in their respective families.

Health Behaviors, Financial Difficulties, and Depressive Symptoms Among Older Adults Across Gender and Race During the COVID-19 Pandemic

Background: COVID-19 deeply affected the health and well-being of older adults. This study examines health behavior change and the interrelationships between health behaviors, financial difficulties, and depressive symptoms among older adults across gender and race during the pandemic. Methods: Using Rounds 1, 5, and 10 of the National Health and Aging Trends Study (NHATS) linked with the NHATS COVID-19 dataset, our sample included Medicare beneficiaries aged 65 or older in the U.S. (N = 3,118). We modeled the interrelationships between health behaviors, financial difficulties, and depressive symptoms using a structural equation model. Results: Female participants reported less walking, more changes in eating habits, less sleeping, and less alcohol consumption during the pandemic than before the pandemic compared to male participants. Compared to White, Non-White participants showed higher proportions of experiencing financial difficulties, less walking, less vigorous activity, and changes in time spent eating and sleeping during than before the pandemic. Financial difficulties was positively associated with depressive symptoms and sedentary behavior. Active behavior was negatively associated with depressive symptoms, while sedentary behavior was positively associated with more depressive symptoms. Discussion: Health professionals should consider health behaviors and financial difficulties when intervening on depressive symptoms experienced by older adults since the pandemic.

Questionnaire-free machine-learning method to predict depressive symptoms among community-dwelling older adults

The 15-item Geriatric Depression Scale (GDS-15) is widely used to screen for depressive symptoms among older populations. This study aimed to develop and validate a questionnaire-free, machine-learning model as an alternative triage test for the GDS-15 among community-dwelling older adults. The best models were the random forest (RF) and deep-insight visible neural network by internal validation, but both performances were undifferentiated by external validation. The AUROC of the RF model was 0.619 (95% CI 0.610 to 0.627) for the external validation set with a non-local ethnic group. Our triage test can allow healthcare professionals to preliminarily screen for depressive symptoms in older adults without using a questionnaire. If the model shows positive results, then the GDS-15 can be used for follow-up measures. This preliminary screening will save a lot of time and energy for healthcare providers and older adults, especially those persons who are illiterate.

Age, period and cohort effects in depression prevalence among Canadians 65+, 1994 to 2018: A multi-level analysis

BACKGROUND

The nature of the Canadian population 65+ has changed considerably over the past several decades. They comprise a larger proportion of the population, are better educated, and are wealthier than previous generations. We estimate the contributions of chronological aging, temporal periods, and birth cohort effects on the trends in the major depressive episode (MDE) prevalence among Canadian seniors from 1994/1995 to 2017/2018.

METHODS

Using data from two sets of national health surveys, the National Population Health Survey (NPHS) and the Canadian Community Health Survey (CCHS). Pooled data on 150,246 survey respondents aged 65+ from 16 repeated cross-sectional surveys are included. Hierarchical regression age-period-cohort models were used to visualize the linear and non-linear effects of age, period, and cohort trends in late-life depression.

RESULTS

We found that: the prevalence of MDE in later life fluctuated non-significantly during the study time period; the probability of developing MDE declined with increasing age from 65 to 80+ (β = -.32, p = .027). The significant quadratic birth cohort predictor showed a non-linear increasing association with the prevalence of MDE from the earlier to later-born cohorts (β = .01, p = .049). We also found that females 65+ were consistently more likely to be depressed than males 65+ (β = .47, p = .007). The significantly negative "age × female" interaction shows that age exerts a greater effect on females' probability of developing MDE than males (β = -.09, p = .011). There were no consistent significant period effects but there were peaks in prevalence around 2001, 2008, and 2012 which corresponded to some recent historical events. Our moderation analysis documents that lower levels of education significantly contributed to the higher rates of depression among cohorts born earlier in the 20th century.

CONCLUSIONS

Our findings show the presence of strong chronological age and cohort effects and weaker period effects on the prevalence of late-life depression in Canadian seniors.

Deep Reinforcement Learning-Based iTrain Serious Game for Caregivers Dealing with Post-Stroke Patients

This paper describes a serious game based on a knowledge transfer model using deep reinforcement learning, with an aim to improve the caretakers’ knowledge and abilities in post-stroke care. The iTrain game was designed to improve caregiver knowledge and abilities by providing non-traditional training to formal and informal caregivers who deal with stroke survivors. The methodologies utilized professional medical experiences and real-life evidence data gathered during the duration of the iTrain project to create the scenarios for the game’s deep reinforcement caregiver behavior improvement model, as well as the design of game mechanics, game images and game characters, and gameplay implementation. Furthermore, the results of the game’s direct impact on caregivers (n = 25) and stroke survivors (n = 21) in Lithuania using the Geriatric Depression Scale (GDS) and user experience questionnaire (UEQ) are presented. Both surveys had favorable outcomes, showing the effectiveness of the approach. The GDS scale (score 10) revealed a low number of 28% of individuals depressed, and the UEQ received a very favorable grade of +0.8.

Validation and Comparison of Three Short Depression Screening Tools Among Chinese Community-Dwelling Older Adults

The current study validated and compared three short Geriatric Depression Scales (GDS), including the GDS-5, D'Ath GDS-4, and van Marwijk GDS-4, among 917 Chinese community-dwelling older adults. The GDS-5, D'Ath GDS-4, and van Marwijk GDS-4 presented satisfactory accuracy against the GDS-15 (area under the curve [AUC] = 0.872 to 0.952), and the GDS-5 and D'Ath GDS-4 had better accuracy than the van Marwijk GDS-4. Satisfactory accuracy (AUC = 0.842 to 0.979) for the three scales was also observed across subgroups by age, sex, education, cognitive function, and multimorbidity. The GDS-5 but not D'Ath GDS-4 and van Marwijk GDS-4 retained a 2-point optimal cutoff for depressive symptoms across subgroups. The GDS-5 (average inter-item correlation coefficient [AIIC] = 0.233) and the D'Ath GDS-4 (AIIC = 0.171) but not van Marwijk GDS-4 (AIIC = 0.128) had acceptable internal consistency. Three scales had stable test-retest reliability within a 1- to 2-week interval (intraclass correlation coefficient = 0.670 to 0.885). The GDS-5 is an accurate and reliable depression screening tool with an invariable optimal cutoff among Chinese community-dwelling older adults. The variable optimal cutoffs for the D'Ath GDS-4 and van Marwijk GDS-4 across subgroups may limit their applicability in this population. [Research in Gerontological Nursing, xx(x), xx-xx.].

Is the analogue cognitive test from the ISPOCD equivalent to the digital cognitive test Mindmore? A protocol for a randomised cross-over study including qualitative interviews with self-reported healthy seniors

INTRODUCTION

Postoperative cognitive decline affects cognitive domains such as executive functions, memory, concentration and information processing. The analogue neuropsychological test developed by the International Study Group of Postoperative Cognitive Dysfunction (ISPOCD) is a well-established test for assessing cognitive performance. However, analogue tests are time-consuming, rarely cost-effective and can be at risk of administration bias. Digital solutions are comparable to analogue ones, have higher degrees of compliance and enable more standardised execution than analogue tests. Currently, there is a lack of recommendations for clinical evaluation of the patient's cognition in the perioperative setting, standard care usually means no cognitive assessments prior or after the surgery. There is a need to find an equivalent neuropsychological test to the ISPOCD to make it accessible and easier to implement in a clinical context for perioperative patients. This study aims to examine how healthy seniors perform on two neuropsychological tests, analogue versus digital and measure equivalency between tests with correlation analysis.

METHODS AND ANALYSIS

This study will use a randomised cross-over design, including qualitative interviews regarding test experiences. Healthy participants ≥60 years of age will be eligible to participate in the study. Cognitive function will be measured by using the ISPOCD test and the Mindmore digital test. The participants will self-report depressive symptoms with the Geriatric Depression Scale-15, user experience of the digital test using a modified version of the System Usability Scale and answer questionnaires targeting their experiences after the tests. Furthermore, according to the Swedish Quality of Recovery Scale, self-reported concentration difficulties will also be measured.

ETHICS AND DISSEMINATION

The study has been approved by the Swedish Ethical Review Authority (Dnr 2021-05486-01) and will follow the principles outlined in the 1964 Helsinki Declaration and its later amendments. Results from this study will be disseminated in peer-reviewed journals, at scientific conferences, and in social media.

Intrinsic Capacity Declines with Elevated Homocysteine in Community-Dwelling Chinese Older Adults

Purpose

Intrinsic capacity (IC) reflects the overall health status of older adults and has great public health significance. But few studies described the related biomarkers for IC. The aim of this study was to investigate the association between homocysteine (Hcy) and IC in older adults.

Participants and Methods

This cross-sectional study included 1927 community-dwelling Chinese older adults aged 60–98 years from May 2020 to December 2020. Data were collected through interviews, physical examinations, and laboratory tests. IC involved five domains of cognition, locomotion, sensory, vitality, and psychology evaluated by the Mini-cog scale, 4-m walk test, self-reported visual and hearing conditions, MNA-SF scale, and GDS-4 scale, respectively. The score of each domain dichotomized as 0 (normal) and 1 (impaired) was added together to an IC total score. Low IC was defined as a score of 3–5, and high IC as 0–2. Hcy was measured by a two-reagent enzymatic assay. A restricted cubic spline regression model was used to explore the non-linear relationship between Hcy and low IC.

Results

Hcy was higher in the low IC group than in the high IC group. Restricted cubic spline analysis revealed a J-shaped nonlinear association between Hcy and low IC. The risk of IC decline was slowly decreased until 8.53 µmol/L of Hcy (OR=0.753, 95% CI=0.520–1.091, P=0.132), and increased with elevations of per 5 µmol/L Hcy afterwards (OR=1.176, 95% CI=1.059–1.327, P=0.005). Among the five domains of IC, Hcy had ORs of 1.116 (1.009–1.247) for cognition impairment, 1.167 (1.055–1.305) for vitality, and 1.160 (1.034–1.303) for psychology per 5 µmol/L increase in Hcy above the change point. Additional sensitivity analysis also demonstrated the nonlinear association between Hcy and low IC.

Conclusion

Hcy had a J-shaped association with low IC. Higher Hcy (Hcy ≥8.53µmol/L) might provide clinical implications for early identifying the risk of low IC.

Validation and comparison of fall screening tools for predicting future falls among older adults

BACKGROUND

Falls are the leading cause of injuries among older adults in the United States (US). Falls are preventable and clinicians are advised to screen for fall risk yearly. There are many falls screening tools and not all have been validated for their ability to predict future falls.

METHODS

We enrolled 1905 community-dwelling older adults into a 13-month study using a probability-based representative panel of the US population recruited from NORC at the University of Chicago's National Frame. Respondents completed a baseline survey, 11 monthly fall calendars, and a final survey. The baseline survey included six falls screening tools (the Stay Independent, Three Key Questions (3KQ), a modified American Geriatric/British Geriatric tool, the short Falls Efficacy-1[FES-I]) and two single screening questions ("I have fallen in the past year" and "How many times did you fall in the past 12 months?"). The baseline and final survey collected demographic and health information, including falls. Sensitivity, specificity, positive and negative likelihood ratios, and corresponding 95% confidence intervals were calculated in SAS using weighted proportions.

RESULTS

There were 1563 respondents who completed the final survey (completion rate 82%). Sensitivity estimates ranged from 22.5% for the short FES-I to 68.7% for the 3KQ. Specificity estimates ranged from 57.9% for the 3KQ to 89.4% for the short FES-I.

CONCLUSIONS

Falls screening tools have varying sensitivity and specificity for predicting the occurrence of a fall in the following 12 months.

Defining and assessing intrinsic capacity in older people: A systematic review and a proposed scoring system

INTRODUCTION

The World Health Organization has introduced the term 'intrinsic capacity' (IC) as a marker of healthy ageing. However, controversy exists on the definition and assessment of IC. We aimed to review the definitions and methods used for the assessment of IC in older adults. In addition, we proposed a new IC scoring method.

METHODS

A systematic search was performed in PubMed, Web of Science, Cochrane Library, Scopus and SPORTDiscus (up to February 10th, 2022) for studies assesing IC in older adults (>60 years).

RESULTS

Thirty-three studies were included. There is overall consensus on the definition of IC as well as on its different dimensions, that is: locomotion, vitality, sensory, cognition and psychological. However, the methods for assessing each of these five dimensions differ substantially across studies and there is no consensus on the best method to compute an eventual global compound score to evaluate IC taking into account all its different dimensions.

CONCLUSIONS

The IC represents a highly relevant clinical concept that has been unfortunately underutilized. We propose a standardization for the assessment of each dimension of IC, with a global 0 (worst) to 10 (highest) score.

The P300, loneliness, and depression in older adults

Depression is associated with high levels of cognitive impairment and increased loneliness among older adults. The current study examines associations between a reliable and robust neural marker of cognitive impairment (i.e., the P300 event-related brain potential [ERP]), loneliness, and depression and assesses the role of loneliness in the P300─depression relationship. In a community sample of 70 older adults between 61 and 75 years, we evaluated cross-sectional associations between depressive symptoms (Geriatric Depression Scale), loneliness (NIH Toolbox), and P300 amplitude measured from the electroencephalogram during a go/no-go task. Results indicated that reduced go and no-go P300 amplitudes were associated with increased depressive symptom severity, with the most unique variance accounted for by a reduced no-go P300 amplitude. Notably, loneliness significantly moderated the no-go P300-depressive symptom severity relationship, such that there was no relationship between the no-go P300 and depressive symptom severity among older adults reporting low levels of loneliness. This finding provides insight into the possibility that social support may offer protection against the depressogenic effects of poor inhibitory control in older adults. Taken together, this study provides a novel examination of the relationships between depression, loneliness, and the P300 ERP in older adults, with important implications for understanding the role of neural inhibition and loneliness in relation to depressive symptomatology.

Prevalence of depression in older adults: A systematic review and meta-analysis

Depression is a prevalent mental disorder in older adults, but the prevalence in older adults varies largely across studies due to differences in regional cultures and screening tools. The objective of this review is to systematically evaluate the global prevalence of depression in older adults. PubMed, Embase, Web of Science and Cochran Library databases were searched independently from 2000 to 2021. Subgroups, sensitivity, and meta-regression analyses were performed to address heterogeneity. Publication bias was evaluated using Egger's test. Forty-eight eligible studies were included in this review. The global prevalence of depression in older adults was 28.4%, with high between-study heterogeneity. The meta-analysis showed that the prevalence of depression in older adults is high although it varied with geographic regions, screening tools, sample sizes and representativeness, and study quality. Therefore, it is necessary to carefully consider appropriate screening tools to estimate the prevalence in different regions of a population.

Effectiveness of the Biography and Life Storybook for Nursing Home Residents: A Quasi-Experimental Study

There are currently limited studies that have examined the use of the biography and life storybook (BLSB) among the Asian older adult populations in the long-term care setting. This quasi-experimental study aimed to examine its impact on life satisfaction scores, depression, and quality of life among nursing home residents in Singapore. Two wards were assigned to either the intervention or control group. The intervention group was assigned to the BLSB intervention, which comprised eight nurse-facilitated structured sessions over three months and their usual daily activities, whereas the control group was assigned to the routine activities. A total of 74 nursing home residents completed the study, with 37 in each group. The BLSB intervention improved depression, quality of life, and life satisfaction for nursing home residents in Singapore, with significant results observed across all three outcomes over the 3-month period. The study findings support the use of BLSB as an effective reminiscence-based intervention for older adults in an Asian nursing home setting.

Concordance of self- and informant-rated depressive symptoms in nursing home residents with Dementia: cross-sectional findings

BACKGROUND

Depression is highly prevalent in nursing home residents living with moderate to severe dementia. However, assessing depressive symptoms in residents with dementia can be challenging and may vary by rater perspective. We aimed to investigate the concordance of, and factors associated with self- and informant-rated depressive symptoms in nursing home residents with dementia.

METHODS

Cross-sectional data was collected from N = 162 nursing home residents with dementia (age: 53-100; 74% women). Self-ratings were assessed with the Geriatric Depression Scale, while the depression and anxiety items of the Neuropsychiatric Inventory were used for informant-ratings. Cohen's Kappa was calculated to determine the concordance of both measures and of each with antidepressant medication. Multivariate associations with sociodemographic variables, self- and informant-rated quality of life, dementia stage, neuropsychiatric symptoms, functional status and antidepressant medication were analysed with linear mixed models and generalized estimating equations.

RESULTS

Concordance between self- and single item informant-rated depressive symptoms was minimal (Cohen's Kappa = .22, p = .02). No concordance was found for self-reported depressive symptoms and the combined informant-rated depression-anxiety score. Self-reported depression was negatively associated with self-rated quality of life (β = -.32; 95%CI: -.45 to -.19, p < .001), informant-rated quality of life (β = -.25; 95%CI: -.43 to -.07, p = .005) and functional status (β = -.16; 95%CI: -.32 to -.01, p = .04), whilst single item informant-rated depression revealed negative associations with informant-rated quality of life (β = -.32; 95%CI: -.52 to -.13, p = .001) and dementia stage (β = -.31; 95%CI: -.52 to -.10, p = .004). The combined informant-rated depression-anxiety score showed negative associations with self-rated quality of life (β = -.12; 95%CI: -.22 to -.03, p = .01) and dementia stage (β = -.37; 95%CI: -.67 to -.07, p = .02) and a positive association with neuropsychiatric symptoms (β = .30; 95%CI: .10 to .51, p = .004). No concordance was found with antidepressant medication.

CONCLUSIONS

In line with our expectations, low agreement and unique association patterns were found for both measures. These findings indicate that both instruments address different aspects of depression und underline the need for comprehensive approaches when it comes to detecting signs of clinically relevant depressive symptoms in dementia.

TRIAL REGISTRATION

The trial was registered with the ISRCTN registry (Trial registration number: ISRCTN98947160 ).

How to Improve the Drafting of Health Profiles

Delineating patients' health profiles is essential to allow for a proper comparison between medical care and its results in patients with comorbidities. The aim of this work was to evaluate the concordance of health profiles outlined by ward doctors and by epidemiologists and the effectiveness of training interventions in improving the concordance. Between 2018 and 2021, we analyzed the concordance between the health profiles outlined by ward doctors in a private hospital and those outlined by epidemiologists on the same patients' medical records. The checks were repeated after training interventions. The agreement test (Cohen's kappa) was used for comparisons through STATA. The initial concordance was poor for most categories. After our project, the concordance improved for all categories of CIRS. Subsequently, we noted a decline in concordance between ward doctors and epidemiologists for CIRS, so a new training intervention was needed to improve the CIRS profile again. Initially, we found a low concordance, which increased significantly after the training interventions, proving its effectiveness.

Frailty as an Independent Risk Factor for Depression in Patients With End-Stage Renal Disease: A Cross-Sectional Study

Background

Depression confers substantial disease burden globally, especially among those with chronic kidney disease (CKD). The presence of depression significantly impairs one's quality of life. Risk factors for depression in patients with CKD remain under-appreciated, and whether frailty, a geriatric phenotype, constitutes a risk factor for depression in this population is unknown.

Methods

We prospectively enrolled patients with end-stage renal disease (ESRD) undergoing hemodialysis for >3 months from National Taiwan University Hospital Yunlin Branch between 2019 and 2021. Clinical, physical, functional, and performance parameters were recorded, followed by frailty/sarcopenia assessment. Depression was screened for using the Geriatric Depression Scale. We analyzed the independent relationship between frailty and depression in these patients, using multiple regression analyses.

Results

Totally 151 patients with ESRD were enrolled (mean 61.1 years, 66.9% male), among whom 16.6% had screening-identified depression. ESRD participants with depression did not differ from those without regarding most parameters except serum creatinine, functional indices, and sarcopenia/frailty status. We found that having greater frail severities was independently associated with a higher probability of depression; having FRAIL- (odds ratio [OR] 5.418) and SOF-based (OR 2.858) frailty independently correlated with a higher depression probability. A linear relation exists between a greater frail severity and the probability of depression. Using a more relaxed criterion for detecting depression, higher SOF scores remained significantly associated with an increased depression risk.

Conclusions

In patients with CKD, frailty independently correlated with a higher probability of having depression. Strategies aiming to attenuate frailty may be able to benefit those with depression simultaneously in this population.

Remote care management for older adult populations with elevated prevalence of depression or anxiety and comorbid chronic medical illness: A systematic review

BACKGROUND

Comorbidity of psychiatric and medical illnesses among older adult populations is highly prevalent and associated with adverse outcomes. Care management is a common form of outpatient support for both psychiatric and medical conditions in which assessment, care planning, and care coordination are provided. Although care management is often remote and delivered by telephone, the evidence supporting this model of care is uncertain.

OBJECTIVE

To perform a systematic review of the literature on remote care management programs for older adult populations with elevated prevalence of depression or anxiety and comorbid chronic medical illness.

METHODS

A systematic review was performed in accordance with PRISMA guidelines. A multi-database search was performed. Articles were included for review if they studied fully remote care management for older adult populations with elevated prevalence of depression or anxiety and chronic medical illness or poor physical health. A narrative synthesis was performed.

RESULTS

A total of 6 articles representing 6 unique studies met inclusion criteria. The 6 studies included 4 randomized controlled trials, 1 case-matched retrospective cohort study, and 1 pre-post analysis. Two studies focused on specific medical conditions. All interventions were entirely telephonic. Five of 6 studies involved an intervention that was 3 to 6 months in duration. Across the 6 studies, care management demonstrated mixed results in terms of impact on psychiatric outcomes and limited impact on medical outcomes. No studies demonstrated a statistically significant impact on health care utilization or cost.

CONCLUSION

Among older adult populations with elevated prevalence of depression or anxiety and comorbid chronic medical illness, remote care management may have favorable impact on psychiatric symptoms, but impact on physical health and health care utilization is uncertain. Future research should focus on identifying effective models and elements of remote care management for this population, with a particular focus on optimizing medical outcomes.

Prevalence of depression in patients with sarcopenia and correlation between the two diseases: systematic review and meta-analysis

BACKGROUND

Depression may be the most common cause of emotional distress later in life and can significantly reduce the quality of life in elderly individuals. Sarcopenia is a syndrome characterized by the continuous loss of skeletal muscle mass and decreased strength and function. In recent years, many studies have shown a correlation between sarcopenia and depression. The present study aimed to investigate the prevalence of depression among individuals with sarcopenia and to ascertain whether sarcopenia is independently associated with depression.

METHODS

We systematically searched the PubMed, Embase, and Google Scholar databases for papers on sarcopenia published up to 31 August 2021. We reviewed the literature on the number of individuals with sarcopenia, the number of individuals with both sarcopenia and depression, and the odds ratio (OR) of sarcopenia to depression. Statistical analyses were performed using Meta-DiSc 1.4 software and Stata version 12.0.

RESULTS

Nineteen articles met the inclusion criteria for review: nine reported both prevalence and ORs, four described prevalence only, and six detailed the ORs only. Regarding prevalence, there were 1476 cases of sarcopenia and 364 of depression in the selected studies; the mean age of the patients was 75.5 years, and the overall prevalence of depression was 0.28 [95% confidence interval (CI): 0.21-0.36]. Significant heterogeneity was noted (P < 0.001; I²  = 92.2%). In the case of ORs, there were 16 869 subjects with a mean age of 73 years; the overall adjusted OR between sarcopenia and depression was 1.57 (95% CI: 1.32-1.86). Significant heterogeneity was noted in the adjusted ORs (P < 0.001; I²  = 75.1%).

CONCLUSIONS

The prevalence of depression in patients with sarcopenia was high relatively, and there was a correlation between sarcopenia and depression.

The diagnostic accuracy of late-life depression is influenced by subjective memory complaints and educational level in an older population in Southern Italy

The prevalence of late-life depression (LLD) depends on the study sample, measurements, and diagnostic approaches. We estimated the 30 item-Geriatric Depression Scale (GDS-30) accuracy against the gold standard LLD diagnosis made with the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR Axis I Disorders, focusing on the prevalence of a late-life major depressive disorder (MDD), in a population-based sample of 843 subjects aged>65 years, subdivided into three groups: normal cognition, subjective memory complaints, and mild cognitive impairment. At the optimal cut-off score (≥4), the GDS-30 showed 65.1% sensitivity and 68.4% specificity for LLD (63% and 66% for late-life MDD, respectively). Using the standard cut-off score (≥10), the GDS-30 specificity reached 91.2%, while sensitivity dropped to 37.7%, indicating a lower screening accuracy [area under the curve(AUC):0.728, 95% confidence interval(CI):0.67-0-78]. The GDS-30 performance was associated with educational level, but not with age, gender, cognition, apathy, and somatic/psychiatric multimorbidity. For subjective memory complaints subjects, at the optimal cut-off score (≥7), the GDS-30 showed better discrimination performances (AUC=0.792,95%CI:0.60-0.98), but again the educational level affected the diagnostic performance. In subjective memory complaints subjects, symptom-based scales like the GDS-30 may feature a better performance for diagnosing depression in older age, but the GDS-30 seems to require adjustment to the patient's educational level.

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

OBJECTIVES

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

METHODS/DESIGN

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

RESULTS

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

CONCLUSIONS

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

Widowhood Impairs Emotional Cognition Among Elderly

Background

The negative impacts of spousal bereavement on the emotional health of the elderly (e.g., depression and anxiety) have been revealed. However, whether widowhood impairs emotional cognition among the elderly is less known. The purpose of this study is to reveal the emotional cognitive deficits among the widowed elderly.

Methods

In this study, we recruited 44 widowed elderly (WE) and 44 elder couples (non-widowed elderly, NWE) and examined their emotional cognition including attention and visual working memory, which were measured by the visual search task and delayed-match-to-sample task, respectively. Three kinds of emotional faces (i.e., sad, angry, and happy) were adopted as the attentional or mnemonic targets.

Results

It revealed that WE had a general deficit in search efficiency across emotional types, while they showed mnemonic deficits in negative faces but not positive faces. Furthermore, the modeling analysis revealed that the level of depression or state anxiety of the elderly moderated the effects of widowhood on the deficits of mnemonic processing, i.e., the deficits were only evident among WE with the high level of depression or state anxiety.

Conclusion

These findings reveal the attentional deficits in sad, angry, and happy faces and the mnemonic deficits in sad and angry faces among elderly who suffer from widowhood and point out the important role of emotional problems such as depression and state anxiety in modulating these emotional cognitive deficits.

Association between the consumption of omega-3-rich fish and depressive symptoms in older adults living in a middle-income country: EpiFloripa Aging cohort study

This study aimed to verify the association between the consumption of omega-3-rich (n-3) fish and depressive symptoms in older adults living in Southern Brazil. This is a cross-sectional analysis with data from the second wave of the EpiFloripa Aging cohort study (2013/2014) including 1,130 individuals aged 60 years or older. The presence of depressive symptoms was measured by the 15-items Geriatric Depression Scale (GDS-15), and the consumption of n-3-rich fish by a question of weekly frequency. The minimum set of variables for adjustment was defined using directed acyclic graph (DAG). Poisson regression with robust error variance was applied (adjusted by Model 1: demographic and socioeconomic variables, Model 2: added behavioral variables, Model 3: added health variables). We identified the prevalence of depressive symptoms in 19% of older adults and 51.8% reported eating n-3-rich fish once a week. Models 1 and 3 showed an inverse association between n-3-rich fish and depressive symptoms. However, the association was reduced when behavioral factors (leisure-time physical activity) were included in Model 2. These findings suggest that n-3-rich fish intake tends to be associated with depressive symptoms in older adults. However, other factors, such as physical exercise, are as pivotal as n-3 fatty acids in preventing the development of depressive symptoms.

Prevalence and Association of Basal Ganglia Calcifications and Depressive Symptoms in Patients With Mild Cognitive Impairment or Dementia

AIM

The aim of this study is to investigate the association between basal ganglia calcification (BGC) and depressive symptoms within older adults with mild cognitive impairment (MCI) or dementia.

METHODS

For this cross-sectional study, we included patients with MCI or dementia who visited the memory clinic between April 2009 and April 2015. All patients underwent a standard diagnostic workup, including assessment of depressive symptoms with the Geriatric Depression Scale and computed tomography imaging of the brain. Computed tomography scans were assessed for presence and severity of BGC. To analyse the association between BGC and depressive symptoms, binary logistic regression models were performed with adjustment for age, sex, cardiovascular risk factors, and cardiovascular diseases.

RESULTS

In total, 1054 patients were included (median age: 81.0 y; 39% male). BGC was present in 44% of the patients, of which 20% was classified as mild, 20% as moderate, and 4% as severe. There were 223 patients (21%) who had a Geriatric Depression Scale score indicative of depressive symptoms. No association was found between the presence or severity of BGC and depressive symptoms.

CONCLUSIONS

Although both BGC and depressive symptoms were common in patients with MCI or dementia, no association was demonstrated between the presence or severity of BGC and depressive symptoms.

Analysis of Factors Associated With Depression in Community-Dwelling Older Adults in Wuhan, China

Objectives: This study aimed to identify the independent factors associated with depression in community-dwelling older adults in Wuhan, China. Methods: Four hundred and seventy older adults (aged ≥65 years) from four communities dwelling on Junshan Street in Wuhan, China were included in this study. Participants completed a questionnaire that asked questions pertaining to age, gender, educational level, income, living situation, care situation, social support, and social engagement. The 30-item Geriatric Depression Scale (GDS-30), the Fried frailty phenotype scale, the activities of daily living (ADL) scale, the mini nutritional assessment scale-short form (MNA-SF), and the Mini-cog scale were used to assess depression, frailty, self-care ability, malnutritional risk, and cognitive dysfunction, respectively. Differences in age, gender, educational level, income, living situation, care situation, social support, social engagement, ADL score, risk of malnutrition, frailty, and cognitive dysfunction between the non-depression (GDS-30 score <10 points) and depression groups (GDS-30 score ≥10 points) were compared using a chi-square test. Moreover, correlations between factors and depression were analyzed using Pearson's correlation. Then, significant variables (p < 0.05) from the chi-square test were included in a multivariable logistic regression model to identify the independent factors associated with depression. Results: The incidence of depression among the participants was 14.04%. Age (p < 0.001), educational level (p < 0.001), living situation (p < 0.001), social support (p = 0.001), ADL score (p = 0.023), frailty (p < 0.001), and cognitive dysfunction (p < 0.001) were all significantly associated with depression, in which age, poor social support, frailty, and cognitive dysfunction were identified as independent factors. Conclusion: Improving social support and effective interventions for frailty and cognitive dysfunction may help relieve depression in community-dwelling older adults.

Exploring the Impact of Flavonoids on Symptoms of Depression: A Systematic Review and Meta-Analysis

Recent evidence suggests that diet modifies key biological factors associated with the development of depression. It has been suggested that this could be due to the high flavonoid content commonly found in many plant foods, beverages and dietary supplements. Our aim was to conduct a systematic review to evaluate the effects of dietary flavonoids on the symptoms of depression. A total of 46 studies met the eligibility criteria. Of these, 36 were intervention trials and 10 were observational studies. A meta-analysis of 36 clinical trials involving a total of 2788 participants was performed. The results showed a statistically significant effect of flavonoids on depressive symptoms (mean difference = −1.65; 95% C.I., −2.54, −0.77; p < 0.01). Five of the 10 observational studies included in the systematic review reported significant results, suggesting that a higher flavonoid intake may improve symptoms of depression. Further studies are urgently required to elucidate whether causal and mechanistic links exist, along with substantiation of functional brain changes associated with flavonoid consumption.

Is the center for epidemiologic studies depression scale as useful as the geriatric depression scale in screening for late-life depression? A systematic review

BACKGROUND

This study analyzed the predictive validity of the Center for Epidemiologic Studies Depression (CES-D) scale for late-life depression (LLD) over the age of 50 years and identified the usefulness of the CES-D compared with the Geriatric Depression Scale (GDS).

METHODS

Electronic searches were performed on the MEDLINE, EMBASE, CINAHL, and PsycINFO databases using the following keywords: depression, depressive disorder, major, and the CES-D scale. The Quality Assessment of Diagnostic Accuracy Studies-2 was applied to assess the risk of bias.

RESULTS

We reviewed 22 studies, including 27,742 older adults aged 50+ years that met the selection criteria. In the meta-analysis, the pooled sensitivity was 0.81 in the CES-D long version and 0.76 in the short version. The sROC AUC was 0.89 (SE=0.01) for the long version and 0.88 (SE=0.04) for the short version. The GDS was only compared to the CES-D long version. The pooled sensitivity was as follows: the CES-D, 0.82; the GDS long version, 0.86; and the GDS short version, 0.87. Further, there was no heterogeneity of 0.0% between studies. The pooled specificity was 0.78 and 0.77, respectively, and the sROC AUC was 0.88 for the CES-D (SE=0.02), 0.89 for the GDS long version (SE=0.04), and 0.91 for the GDS short version (SE=0.03).

LIMITATIONS

We could not consider cognitive function of older adults.

CONCLUSIONS

The CES-D showed similar predictive validity compared to the GDS developed in older adults. The CES-D is a useful tool that can be used for LLD screening in older adults over 50 years old.

Plasma 25-hydroxyvitamin D levels, quality of life, inflammation and depression in older adults: Are they related?

BACKGROUND AND OBJECTIVES

This study aimed to determine whether there is an association between inflammation and depression taking into account the effect of several confounders, but specially plasma 25-hydroxyvitamin D (25[OH]D) levels.

MATERIAL AND METHODS

A cross-sectional study was conducted on adults (n = 346) aged 60 years or older recruited from primary healthcare centres. Depression was assessed by the Geriatric Depression Scale (GDS), while plasma 25(OH)D and inflammatory cytokines were measured following routine biochemical laboratory protocols.

RESULTS

Subjects were divided into two subgroups according to their depression status, and matched in their baseline conditions using random forest-based propensity scores. Both groups were rather similar in regard to most variables, apart from quality of life (p < 0.001) and plasma levels of IL-6 (p = 0.03). The overall prevalence of vitamin D deficiency was 36.3% (95% Confidence Interval [95% CI], 30.2%-42.5%), without a significant difference between depression groups (p = 0.2). A significant association was observed between GDS score and plasma IL-6 levels only among those with SF-6D score between 0.26 and 0.50 (p = 0.001).

CONCLUSIONS

The association between inflammation and depression is more likely to be due to a moderation influence of quality of life rather than plasma 25(OH)D levels. However, further studies are needed to ascertain the effect of a poor quality of life leading to chronic inflammation and poor health upon longer periods of follow-up.

Factors associated with fear of falling among frail older adults

Some factors increase the fear of falling in frail older adults. Our aim is to quantify the influence of these factors. This cross-sectional study involved 229 community-dwelling prefrail and frail older adults aged 70 years and older. Fear of falling was moderate in 38.9% of our sample and high in 12.2%. Higher values were observed in women, those living alone, and those meeting criteria for slowness and feelings of exhaustion. A linear regression showed that being a woman, a history of falls, and depressive symptoms were related to higher fear of falling, while high levels of independence in basic and instrumental activities of daily living, along with good gait and balance, were associated with lower fear of falling. Screening for depressive symptoms and fear of falling in the comprehensive geriatric assessment of frail community-dwelling older adults could help to support preventive strategies.

Accuracy of the Geriatric Depression Scale (GDS)-4 and GDS-5 for the screening of depression among older adults: A systematic review and meta-analysis

BACKGROUND

The Geriatric Depression Scale (GDS) is a widely used instrument to assess depression in older adults. The short GDS versions that have four (GDS-4) and five items (GDS-5) represent alternatives for depression screening in limited-resource settings. However, their accuracy remains uncertain.

OBJECTIVE

To assess the accuracy of the GDS-4 and GDS-5 versions for depression screening in older adults.

METHODS

Until May 2020, we systematically searched PubMed, PsycINFO, Scopus, and Google Scholar; for studies that have assessed the sensitivity and specificity of GDS-4 and GDS-5 for depression screening in older adults. We conducted meta-analyses of the sensitivity and specificity of those studies that used the Diagnostic and Statistical Manual of Mental Disorders (DSM) or the International Classification of Diseases-10 (ICD-10) as reference standard. Study quality was assessed with the QUADAS-2 tool. We performed bivariate random-effects meta-analyses to calculate the pooled sensitivity and specificity with their 95% confidence intervals (95% CI) at each reported common cut-off. For the overall meta-analyses, we evaluated each GDS-4 version or GDS-5 version separately by each cut-off, and for investigations of heterogeneity, we assessed altogether across similar GDS versions by each cut-off. Also, we assessed the certainty of evidence using the GRADE methodology.

RESULTS

Twenty-three studies were included and meta-analyzed, assessing eleven different GDS versions. The number of participants included was 5048. When including all versions together, at a cut-off 2, GDS-4 had a pooled sensitivity of 0.77 (95% CI: 0.70-0.82) and a pooled specificity of 0.75 (0.68-0.81); while GDS-5 had a pooled sensitivity of 0.85 (0.80-0.90) and a pooled specificity of 0.75 (0.69-0.81). We found results for more than one GDS-4 version at cut-off points 1, 2, and 3; and for more than one GDS-5 version at cut-off points 1, 2, 3, and 4. Mostly, significant subgroup differences at different test thresholds across versions were found. The accuracy of the different GDS-4 and GDS-5 versions showed a high heterogeneity. There was high risk of bias in the index test domain. Also, the certainty of the evidence was low or very low for most of the GDS versions.

CONCLUSIONS

We found several GDS-4 and GDS-5 versions that showed great heterogeneity in estimates of sensitivity and specificity, mostly with a low or very low certainty of the evidence. Altogether, our results indicate the need for more well-designed studies that compare different GDS versions.

Unmet need for mental health services in indolent lymphoma: age differences over one-year post-diagnosis

This study examined distress and mental health service use in patients with newly diagnosed indolent lymphoma over the first-year post-diagnosis, as well as differences by age. Patients with indolent lymphoma completed online self-report measure of distress and whether they accessed mental health services (Yes/No) every four months for a total of four surveys. The baseline sample consisted of 74 patients; 41.9% were age 65 years and older, 24.3% endorsed elevated distress, and 16.2% accessed mental health services. Across time, less than half (36.4-46.7%) of distressed patients accessed mental health services. In patients younger than 65 years, a greater proportion of distressed than non-distressed patients accessed mental health services. However, distress was not associated with mental health service use in older adults. Future research should evaluate issues driving distress and access to mental health care in patients with indolent lymphomas, including age-based approaches.

Depression and Severity of Glaucoma Among Older Adults in Urban and Suburban Areas

PRCIS

Depression increases with severity of visual field defect in older adults with primary open-angle glaucoma (POAG).

PURPOSE

This study aimed to determine the prevalence of depression among patients with POAG and examine the relationship between depression and the severity of POAG in older adults.

MATERIALS AND METHODS

Three hundred and sixty patients with POAG aged 60 years or above were recruited from 2 tertiary centers located in an urban and suburban area. The participants were stratified according to the severity of their glaucoma based on the scores from the modified Advanced Glaucoma Intervention Study (AGIS) to mild, moderate, severe, and end stage. Face-to-face interviews were performed using the Malay Version Geriatric Depression Scale 14 (mGDS-14) questionnaire. Depression is diagnosed when the score is ≥8. One-way analysis of variance was used to compare the subscores between the groups. Multifactorial analysis of variance was also applied with relevant confounding factors.

RESULTS

Depression was detected in 16% of older adults with POAG; a higher percentage of depression was seen in those with end stage disease. There was a significant increase in the mean score of mGDS-14 according to the severity of POAG. There was evidence of an association between depression and severity of visual field defect (P<0.001). There was a significant difference in mGDS-14 score between the pairing of severity of POAG [mild-severe (P=0.003), mild-end stage (P<0.001), moderate-severe (P<0.001), and moderate-end stage (P<0.001)] after adjustment to living conditions, systemic disease, and visual acuity.

CONCLUSION

Ophthalmologists should be aware that older adults with advanced visual field defects in POAG may have depression. The detection of depression is important to ensure adherence and persistence to the treatment of glaucoma.

Performance of the Geriatric Depression Scale-15 with Older Adults Aged over 65 Years: An Updated Review 2000-2019

OBJECTIVES

This up-to-date systematic review and meta-analysis aimed to examine the predictive validity of the Geriatric Depression Scale-15 (GDS-15) for screening depression in older adults aged over 65 years.

METHODS

Electronic searches were performed on the MEDLINE, EMBASE, CINAHL, and PsycINFO database using the following keywords: depression, depressive disorder, major, geriatric depression scale, and geriatric depression scale short. The Quality Assessment of Diagnostic Accuracy Studies-2 was applied to assess the risk of bias in diagnostic studies.

RESULTS

Thirty-one studies that included 8,897 older adults were analyzed. The pooled sensitivity of the GDS-15 was 0.80 (95% CI:0.78 to 0.82), its pooled specificity was 0.79 (95% CI:0.78 to 0.80), the area under the curve (AUC) was 0.89 (SE = 0.01) and the Q* value was 0.82 (SE = 0.01). The subgroup analysis revealed that the pooled sensitivity and specificity of the GDS-15 were higher in older adults with normal cognitive function than in those with cognitive impairment.

CONCLUSIONS

These finding suggest that the GDS-15 may be more accurate for screening depression in older adults with normal cognitive function.

CLINICAL IMPLICATIONS

The utility the GDS-15 may be restricted because its diagnostic accuracy is slightly lower among older adults with cognitive impairment.

Screening for perinatal depression with the Patient Health Questionnaire depression scale (PHQ-9): A systematic review and meta-analysis

OBJECTIVES

Perinatal depression (PND) is a prevalent and disabling problem both during pregnancy and the postpartum period. The legacy screening measure has been the Edinburgh Postnatal Depression Scale (EPDS). This systematic review examines the validity of the PHQ-9 as a screener for PND.

METHODS

The following databases were searched from January 2001 (when the PHQ-9 was first published) through June 2020: MEDLINE, Embase, and PsychInfo. Studies that compared the PHQ-9 to a criterion standard psychiatric interview were used to determine the operating characteristics of sensitivity, specificity and area under the curve (AUC). Studies comparing the PHQ-9 to the EPDS and other depression scales evaluated convergent validity.

RESULTS

A total of 35 articles were eligible for criterion (n = 10) or convergent (n = 25) validity. Meta-analysis of the 7 criterion validity studies using the standard PHQ-9 cut point ≥10 showed a pooled sensitivity, specificity and AUC of 0.84, 0.81 and 0.89, respectively. Operating characteristics of the PHQ-9 and EPDS were nearly identical in head-to-head comparison studies. The median correlation between the PHQ-9 and EPDS was 0.59, and categorical agreement was moderate.

CONCLUSIONS

The PHQ-9 appears to be a viable option for perinatal depression screening with operating characteristics similar to the legacy EPDS.

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.

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.
