The role of spousal loss in the development of depressive symptoms in the elderly - implications for diagnostic systems

Factors Contributing to Well-Being in Japanese Community-Dwelling Older Adults Who Experienced Spousal Bereavement

PURPOSE

Providing support for older adults after spousal bereavement is crucial for psychological recovery through the grieving process and for promoting a healthy and happy remainder of life. The current study aimed to understand factors influencing well-being among Japanese community-dwelling older adults who experienced spousal bereavement by evaluating how their roles and activities affected their psychological well-being following the loss.

METHOD

We conducted a cross-sectional, anonymous, self-administered questionnaire survey of 332 older adults who had experienced death of a spouse in later adulthood.

RESULTS

Identified factors that affected well-being after spousal loss were sex, ability to go out without assistance from others, long duration since spousal loss, having a hobby, and adopting a life-oriented approach to cope with bereavement. Well-being following spousal loss was influenced by participants' activities and roles.

CONCLUSION

Findings of the current study provide potentially valuable suggestions for surviving spouses and their supporters when coping with grief following spousal loss. [Research in Gerontological Nursing, 17(3), 121-130.].

Types of bereavement and depressive symptoms among older adults: Does race/ethnicity matter?

AIM

To explore racial/ethnic differences in relation between types of bereavement and depressive symptoms among older adults in the USA.

METHODS

The sample limited to racially/ethnically diverse adults aged ≥55 (n = 879) was drawn from the third wave of the National Social Life, Health, and Aging Project (NSHAP). The NSHAP provides self-identified racial/ethnic categories (non-Hispanic Whites, Blacks, and Hispanics) of respondents who were categorized into three groups by experience of bereavement: non-loss, spousal loss, and parental loss. Using the weights, a two-way analysis of covariance with Bonferroni post-test was conducted to explore the main effect of types of loss and race/ethnicity and their interaction effects on depressive symptoms.

RESULTS

Spousal loss reported higher levels of depressive symptoms than non-loss or parental loss. Based on the interaction between types of loss and race/ethnicity; however, distinctive patterns were observed. Blacks and Hispanics who lose a parent reported significantly higher levels of depressive symptoms than non-Hispanic Whites did.

CONCLUSIONS

An increase in depressive symptoms after bereavement manifested distinctively based on racial/ethnic background and the relationship with the deceased. This implies that it is necessary to develop coping strategies concerning race/ethnicity and whom they lose. Geriatr Gerontol Int 2024; 24: 266-272.

Disclosure of Spousal Death to Patients with Dementia: Attitude and Actual Behavior of Care Managers

As the number of dementia patients increases, there is a need to protect patients' right to know. However, in reality, there are cases in Japan where spouses' deaths are concealed from patients. We conducted a questionnaire survey of care managers (CMs) to obtain their attitude and actual behavior regarding the disclosure of a spouse's death to patients with dementia. A self-administered, anonymous questionnaire survey was implemented at academic meetings attended by CMs from March to December 2019, inquiring about experiences with spousal deaths of patients with dementia, disclosure rates, behavioral and psychological symptoms of dementia, and depression. Over 80% had experienced the spousal death of a patient with dementia; the percentage of CMs who had implemented the disclosures varied widely. About 18% had experienced worsening behavioral and psychological symptoms of dementia (BPSD), and 26% had worsening depression as a result of the disclosure. About 83% of respondents were positive about disclosure, but about 44% did so less than 50% of the time. This study is the first to reveal the current state of CMs' policies and behaviors regarding the disclosure of spousal death to patients with dementia in Japan. Family members' wishes and the possibility of BPSD put a relatively large number of caregivers in a dilemma regarding disclosure.

The emotional impact of disrupted environmental contexts: Enrichment loss and coping profiles influence stress response recovery in Long-Evans rats

With increasing rates of anxiety and mood disorders across the world, there is an unprecedented need for preclinical animal models to generate translational results for humans experiencing disruptive emotional symptoms. Considering that life events resulting in a perception of loss are correlated with depressive symptoms, the enrichment-loss rodent model offers promise as a translational model for stress-initiated psychiatric disorders. Additionally, predisposed temperament characteristics such as coping styles have been found to influence an individual's stress response. Accordingly, male rats were profiled as either consistent or flexible copers and assigned to one of three environments: standard laboratory housing, enriched environment, or enriched environment exposure followed by downsizing to standard laboratory cages (i.e., enrichment-loss group). Throughout the study, several behaviors were assessed to determine stress, social, and reward-processing responses. To assess recovery of the stress response, fecal samples were collected following the swim stress in 3-h increments to determine the recovery trajectory of corticosterone (CORT) and dehydroepiandrosterone (DHEA) metabolite levels. Upon death, neural markers of neuroplasticity including doublecortin, glial fibrillary acidic factor, and brain-derived neurotrophic factor were assessed via immunohistochemistry. Results indicated the flexible coping animals in the continuous enriched group had higher DHEA/CORT ratios (consistent with adaptive responses in past research); furthermore, the enrichment-loss animals exhibited a blunted CORT response throughout the assessments and enriched flexible copers had faster CORT recovery rates than consistent copers. Standard housed animals exhibited less exploratory behavior in the open field task and continuous enriched, flexible rats consumed more food rewards than the other groups. No differences in neuroplasticity neural markers were observed. In sum, the results of the present study support past research indicating the disruptive consequences of enrichment-loss, providing evidence that the model represents a valuable approach for the investigation of neurobiological mechanisms contributing to interindividual variability in responses to changing experiential landscapes.

Religious Coping Styles and Depressive Symptoms in Geriatric Patients: Understanding the Relationship through Experiences of Integrity and Despair

Older persons are often confronted with challenging events in their lives. Religion can offer them a way to deal with these challenges. The study of religious coping styles helps us to understand how people find support in their religion or wrestle with aspects of their religion when they are confronted with difficulties. Especially when older adults face illness and hospitalization, religious coping styles might be triggered. Despite the fact that the public role of religion, especially Christianity, is diminishing in West European societies, a large group of Belgian geriatric patients call themselves religious. Previous studies have shown that there is a link between positive/negative religious coping styles and the depressive symptoms that often occur in older adults. More recently, some scholars have emphasized that this relationship is more complex. Therefore, this paper investigates the role of one possible underlying mechanism between positive/negative religious coping styles and depressive symptoms in geriatric patients, namely the developmental process of integrity and despair as two factors within this mechanism. One hundred thirty-nine geriatric inpatients from three hospitals in Belgium who reported to feel religiously affiliated were involved in this study. Our results indicate that experiences of integrity and despair function as an explanatory pathway in the relationship between negative religious coping styles and depressive symptoms. Further, a direct link was found between both when accounting for experiences of integrity and despair. For positive religious coping styles, no direct or indirect relationship with depressive symptoms was found. In healthcare, geriatric caregivers need to be aware of the interaction between positive and negative religious coping styles, the developmental process of integrity and despair, and depressive symptoms.

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.

Loss and bereavement in late life (60+): Study protocol for a randomized controlled trial regarding an internet-based self-help intervention

BACKGROUND

The death of a close person is a highly stressful, yet common life event in later life. While most individuals seem to cope well with bereavement, a substantial proportion of older individuals suffer from prolonged grief symptoms. E-mental health interventions have been shown to be efficient for a variety of psychological illnesses. Yet, there is a large research gap of studies with a special focus on older adults. This study protocol describes a randomized controlled trial for an internet-based self-help intervention addressing bereavement and loss in adults aged 60 years and over. The self-management intervention is based on techniques of cognitive behavioral therapy and consists of 8 modules. The objective of the AgE-health study is to evaluate the effectiveness and acceptability of this intervention in comparison to a bibliotherapy control group.

METHODS

The AgE-health study aims at implementing a randomized controlled trial. Eligible participants aged 60+ years will be randomly allocated to an intervention group (access to the intervention) or to an active control group (access to bibliotherapy). Primary outcome is the reduction in grief symptoms (13-item Prolonged Grief Inventory); secondary outcomes are depression, social activity and network, quality of life, self-efficacy, satisfaction with the intervention/bibliotherapy, loneliness, acceptability, up-take and adherence. Assessments will take place before the intervention (baseline) as well as 4 months (follow-up 1) after the intervention.

DISCUSSION

This study addresses an under-recognized and understudied mental health burden in later life and may add valuable insight into our knowledge about the effectiveness of eHealth interventions for loss and bereavement in late life. To our knowledge, the AgE-health study will be the first randomized controlled trial to evaluate the effectiveness of an internet-based intervention targeting prolonged grief in adults aged 60 years and over.

TRIAL REGISTRATION

The study has been registered at the German Clinical Trials Register (Identifier: DRKS00020595, Registered 30th July 2020, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00020595).

Do self-reported hearing and visual impairments predict longitudinal dementia in older adults?

BACKGROUND

Sensory impairments have been associated with dementia in older adults. However, the contribution of different impairments and how they interact in the development of dementia is not clear. We examined the independent and interaction effects of hearing impairment (HI) and visual impairment (VI) on incident dementia.

DESIGN

Multi-centric population-based prospective cohort study.

SETTING

Data were taken from the AgeDifferent.de platform, pooling participants aged 75 and older from the German LEILA75+ and AgeCoDe/AgeQualiDe cohorts.

PARTICIPANTS

Older adults (N = 3497) with mean age 79.8 years, 67.2% female.

MEASUREMENTS

Standardized interviews and questionnaires were used to assess self-reported HI and VI at baseline and all-cause dementia in 9 follow-ups, spanning over 20 years.

METHODS

Competing risk regression models were conducted to test the main and interaction effects of HI and VI on dementia incidence, adjusting for established risk factors of dementia and accumulated mortality.

RESULTS

HI and VI at baseline were reported by 30.3% and 16.6% of individuals, respectively. Adjusting for baseline information on sociodemographics, substance use, cognitive functioning and morbidity, and controlling for accumulated mortality risk, HI (sHR 1.16, 95% CI 1.04-1.30, p = 0.011) but not VI (sHR 1.07, 95% CI 0.90-1.28, p = 0.462) was significantly associated with incident dementia. There was no interaction between HI and VI (sHR 1.09, 95% CI 0.81-1.46, p = 0.567).

CONCLUSIONS

Hearing impairment is associated with an increased incidence of all-cause dementia in older adults. There is no excess risk or risk compensation through the additional presence or absence of visual impairment. Early prevention measures for hearing impairment might help to reduce the long-term risk of dementia.

Grief and loss in old age: Exploration of the association between grief and depression

BACKGROUND

The proportion of older adults is increasing due to demographic changes. Depression belongs to the most common mental disorders in late life. The loss of an emotionally significant person is a risk factor for the development of depression. The aim of this study is to analyze the association between depression and grief burden resulting from loss. Based on prior evidence, we examined loneliness as a possible mediator and social support as possible moderator of this association.

METHODS

The cross-sectional analyses are based on a sample (N = 863) of study participants aged 75+ (M = 81.4 years, SD = 4.4, 62.2% female) with loss experience deriving from the multicenter prospective German cohort study AgeMooDe. Regression analyses (moderated mediation) were performed.

RESULTS

With increasing age (β = 0.10, p = .005) and grief burden (β = 0.33, p <. 001) depression severity increased. There was an indirect mediating effect of loneliness on the correlation of grief burden and depression (b = 0.04, CI [0.03, 0.05]), but no moderating effect of social support on the correlation of grief burden and loneliness. People living alone had a significantly higher risk of depression, increased loneliness and lack of social support.

LIMITATIONS

Assessments were based on self-reporting and recorded dimensionally. The cross-sectional design limits conclusions about directions and causality of associations. Sampling bias cannot be completely excluded.

CONCLUSION

The study provides empirical evidence and a better understanding of the association between grief and depression among the very old and the mediating role of loneliness.

Predicting depression among the elderly by stressful life events and coping strategies

Background and Aim:

Aging is a stage during which stressful events occur frequently. The method of coping with this stress can play an important role in an elderly's mental health. The present study aimed at investigating the role of coping strategies in stressful life events associated with depression.

Method:

The present study was a correlational one conducted by structural equation analysis. As many as 841 elderly people were selected from the general population by adopting a cluster sampling method. Beck's Depression Inventory as well as strategies of coping with stress and stressful events were applied.

Results:

The model test, analyzed by AMOS by using path analysis, indicated that age is positively associated with stressful life events and depression. The “stressful life events” variable is directly and indirectly associated with depression. The emotion-focused coping strategies were positively associated with depression, and problem-focused coping strategies were negatively associated with depression.

Conclusion:

As an individual grows older and experiences stressful life events, his/her depression increases. Elderly people with problem-focused coping strategies are likely to experience less depression.

Internet Use in Old Age: Results of a German Population-Representative Survey

Background

The internet has the potential to foster healthy lifestyles and to support chronic disease management. Older adults could benefit from using the internet and other information and communication technology to access health-related information and interventions available online.

Objective

The aim of this study was to investigate factors influencing internet use in older and oldest age groups and to determine the frequency of internet use for health-related purposes.

Methods

Using data from a nationally representative telephone survey of older adults aged 75 years and over, a sample of 999 people was assessed using structured clinical interviews. Descriptive and binary logistic regression analyses were performed.

Results

Overall, 42.6% (418/999) of participants used the internet. Among those, 55.7% (233/417) searched the internet for health-related information. Regression analyses revealed that internet use was significantly associated with younger age (odds ratio [OR] 0.89, 95% CI 0.85-0.92; P<.001), male gender (OR 2.84, 95% CI 2.02-4.00; P<.001), higher education levels (OR 6.69, 95% CI 4.48-9.99; P<.001), a wider social network (OR 1.04, 95% CI 1.01-1.07; P=.01), higher health-related quality of life (OR 1.02, 95% CI 1.00-1.03; P=.006), lower levels of depressive symptoms (OR 0.89, 95% CI 0.80-0.99; P=.04), and higher rates of chronic illness (OR 1.12, 95% CI 1.04-1.21; P<.004).

Conclusions

This study provides population-representative data on internet use in old age in Germany. People in the older and oldest age groups participate in online activities. Understanding the factors that are associated with older adults internet use can contribute to developing tailored interventions and eHealth (electronic health) services to improve well-being in older adults.

Unmet care needs in the oldest old with social loss experiences: results of a representative survey

Background

Loss experiences such as the loss of a spouse, a close relative or significant others become more likely in old age and may be strongly related to specific unmet health care needs. These unmet needs may often remain undetected and undertreated followed by a negative impact on well-being and social role functioning. The present study aims at exploring the relationship between loss experiences and specific unmet care needs in old age.

Methods

As part of the study „Need assessment in the oldest old: application, psychometric examination and establishment of the German version of the Camberwell Assessment of Need for the Elderly (CANE)”, the adapted German version of the CANE was used in a population-representative telephone survey in a sample of 988 individuals aged 75+ years. Loss experiences within the last 12 months were assessed within the structured telephone survey. Descriptive and interferential statistical analyses were run in order to examine the association between loss experiences and occurring unmet care needs.

Results

Overall, 29.7% of the oldest old reported at least one social loss with other relatives losses being the most frequent (12.5%), followed by non-family losses (10.7%). A significant relationship between loss experiences and a higher number of unmet care needs was observed, especially for close family losses. Other risk factors for unmet care needs were age, marital status, depression, social support and morbidity.

Conclusions

This study provides, for the first time in Germany, data on the association between loss experiences and unmet needs. These findings may substantially contribute to the development of loss-specific interventions, effective treatment and health care planning for the bereaved elderly.

Are older men more vulnerable to depression than women after losing their spouse? Evidence from three German old-age cohorts (AgeDifferent.de platform)

BACKGROUND

Old age is accompanied by a higher risk of losing a spouse. This study aims to longitudinally investigate the effect of widowhood on depression severity with a special focus on sex differences. We examine depression before and after widowhood in men and women separately to investigate which sex is at greater risk after losing a spouse.

METHODS

Data came from the AgeDifferent.de platform, which includes three pooled old age cohort studies. In order to examine factors associated with depression over time, we applied a linear hybrid mixed-effects regression model for the overall sample and analysed additional separate models for men and women.

RESULTS

Of 2470 respondents (mean age at baseline 79.2 (SD 3.64) years), 1256 were men. In total, 209 men and 332 women experienced spousal bereavement after baseline. In general, both sexes showed higher depression severity after widowhood. However, there were significant sex differences. Widowed men were more prone to subsequent depression than widowed women. In terms of depression severity, widowed men differed significantly compared to non-widowed men; however, this was not the case for women.

LIMITATION

We harmonized three cohort studies which used different measurement scales for depression and different recruitment procedures.

CONCLUSION

Our study showed that although both genders suffer from losing a spouse, men are more prone to subsequently develop depressive symptoms. Raising the awareness among practitioners for sex-specific differences as well as developing tailored interventions for both widowed men and women should be considered.

AgeWell.de - study protocol of a pragmatic multi-center cluster-randomized controlled prevention trial against cognitive decline in older primary care patients

BACKGROUND

In the absence of treatment options, the WHO emphasizes the identification of effective prevention strategies as a key element to counteract the dementia epidemic. Regarding the complex nature of dementia, trials simultaneously targeting multiple risk factors should be particularly effective for prevention. So far, however, only few such multi-component trials have been launched, but yielding promising results. In Germany, comparable initiatives are lacking, and translation of these complex interventions into routine care was not yet done. Therefore, AgeWell.de will be conducted as the first multi-component prevention trial in Germany which is closely linked to the primary care setting.

METHODS

AgeWell.de will be designed as a multi-centric, cluster-randomized controlled multi-component prevention trial. Participants will be older community-dwelling general practitioner (GP) patients (60-77 years; n = 1,152) with increased dementia risk according to CAIDE (Cardiovascular Risk Factors, Aging, and Incidence of Dementia) Dementia Risk Score. Recruitment will take place at 5 study sites across Germany. GP practices will be randomized to either intervention A (advanced) or B (basic). GPs will be blinded to their respective group assignment, as will be the statistician conducting the randomization. The multi-component intervention (A) includes nutritional counseling, physical activity, cognitive training, optimization of medication, management of vascular risk factors, social activity, and, if necessary, further specific interventions targeting grief and depression. Intervention B includes general health advice on the intervention components and GP treatment as usual. We hypothesize that over the 2-year follow-up period the intervention group A will benefit significantly from the intervention program in terms of preserved cognitive function/delayed cognitive decline (primary outcome), and other relevant (secondary) outcomes (e.g. quality of life, social activities, depressive symptomatology, cost-effectiveness).

DISCUSSION

AgeWell.de will be the first multi-component trial targeting risk of cognitive decline in older adults in Germany. Compared to previous trials, AgeWell.de covers an even broader set of interventions suggested to be beneficial for the intended outcomes. The findings will add substantial knowledge on modifiable lifestyle factors to prevent or delay cognitive decline.

Loss of Environmental Enrichment Elicits Behavioral and Physiological Dysregulation in Female Rats

Chronic stress drives behavioral and physiological changes associated with numerous psychiatric disease states. In rodents, the vast majority of chronic stress models involve imposition of external stressors, whereas in humans stress is often driven by internal cues, commonly associated with a sense of loss. We previously exposed groups of rats to environmental enrichment (EE) for a protracted period (1 month), followed by removal of enrichment (ER), to induce an experience of loss in male rats. ER enhanced immobility in the forced swim test (FST), led to hypothalamic pituitary adrenal (HPA) axis hypoactivity, and caused hyperphagia relative to continuously enriched (EE), single-housed (Scon) and pair-housed (Pcon) groups, most of which were reversible by antidepressant treatment (Smith et al., 2017). Here, we have applied the same approach to study enrichment loss in female rats. Similar to the males, enrichment removal in females led to an increase in the time spent immobile in the FST and increased daytime food intake compared to the single and pair-housed controls. Unlike males, ER females showed decreased sucrose preference, and showed estrus cycle-dependent HPA axis hyperactivity to an acute restraint stress. The increase in passive coping (immobility), anhedonia-like behavior in the sucrose preference test and HPA axis dysregulation suggest that enrichment removal produces a loss phenotype in females that differs from that seen in males, which may be more pronounced in nature.

Prevalence of Anxiety Symptoms and Their Association With Loss Experience in a Large Cohort Sample of the Oldest-Old. Results of the AgeCoDe/AgeQualiDe Study

Background: Anxiety in adults is a common mental health problem. However, studies on anxiety in the oldest-old are lacking. We sought to identify the age- and gender-specific prevalence of anxiety symptoms in a large sample of general practice patients. Furthermore, we investigated relevant associations of anxiety specifically with respect to recent experience of loss. Methods: Based on the German Study on Ageing, Cognition and Dementia in general practice patients, a sample of 897 patients aged 82 years and older was assessed. Anxiety was assessed using the short form of the Geriatric Anxiety Inventory (GAI-SF). For the assessment of loss, patients were asked whether there were cases of death in their closer social environment since the last assessment. Descriptive and logistic regression analyses were run. Results: Of the oldest-old individuals (aged 82+ years, mean age: 86.8), 14.5% (95% CI 12.4-16.8) suffered from anxiety symptoms. Highest prevalence rates were found for 82- to 85-year-old women (17.2%, 95% CI 12.6-22.1) and for 86- to 90-year-old patients (both sexes) in general (15.9%, 95% CI 12.6-19.2). Older individuals who experienced cases of death in their close social environment within the last 18 months had almost twice the odds [odds ratio (OR) 1.91, 95% confidence interval (CI) 1.15-3.17] of reporting anxiety compared to those without a recent loss. As expected, depression and impaired cognitive status were associated with the presence of anxiety symptoms. No relation was found between social network, gender, age, frailty, or physical illness and anxiety in regression analysis. Conclusions: This study provides for the first time age- and gender-specific prevalence rates of anxiety symptoms and associated risk factors among a large population-based sample of oldest-old primary care attenders. Anxiety is highly prevalent in individuals aged 82 years and older. Depression, impaired cognitive status, and recent experience of loss are associated with late-life anxiety. Our findings support the idea that recent experience of loss should be taken seriously in the context of clinical practice with respect to diagnosing and treating anxiety in old age.

Loss experiences in old age and their impact on the social network and depression- results of the Leipzig Longitudinal Study of the Aged (LEILA 75+)

BACKGROUND

Loss experiences and bereavement are common among the oldest old. This study aims to investigate the effects of loss experiences and the social network type on depression in old age.

METHODS

As part of the Leipzig Longitudinal Study of the Aged (LEILA 75+), a representative population-based cohort study, 783 persons aged 75+ years were assessed via standardized interviews including the Practitioner Assessment of Network Type Instrument (PANT) and the Center for Epidemiologic Studies-Depression Scale (CES-D). Effects of loss experiences and network type on depression were analysed cross-sectionally (baseline survey) using logistic regressions. Effects over time were analysed longitudinally (follow-up1 and follow-up2) using hybrid techniques.

RESULTS

More than half of the elderly (57%) continuously lived in a restricted network. Only 12.1% lived in an integrated network. Although 30.9% had a change in their network, no significant association with loss experiences was found. Nevertheless, loss experiences (OR 7.56 (1.60-35.72)) and a restricted social network (OR 4.08 (1.52-10.95)) appeared to be the significant predictors of depression.

LIMITATIONS

Our study captures only a selected time window of the individual life and loss experience was only assessed at the time of the baseline survey.

CONCLUSION

Our findings revealed that elderly individuals, who experienced social loss or lived in restricted social networks, were more likely to develop depression compared to individuals who lived in integrated social networks or without loss experiences. The social integration of elderly individuals is an urgent issue that should be addressed in order to reduce depression in old age.

Impact of falls on depressive symptoms among the oldest old: Results from the AgeQualiDe study

OBJECTIVE

The purpose of this study was to examine the impact of falls on depressive symptoms among the oldest old in Germany longitudinally.

METHODS

Data were used from 2 waves of the multicenter prospective cohort "Study on needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" (AgeQualiDe). This study covers primary care patients ≥85 years (at baseline: n = 547, average age of 88.9 ± 3.0 years; ranging from 85 to 100 years). General practitioner-diagnosed falls were used as explanatory variable. The Geriatric Depression Scale was used as outcome measure.

RESULTS

Linear fixed effects regressions showed that the occurrence of falls is associated with an increase in depressive symptoms (β = .60, P = .02), whereas changes in marital status, ageing, social support, functional decline (instrumental activity of daily living), cognitive impairment, and an increase in chronic diseases did not affect depressive symptoms. In sensitivity analysis, an increase in depressive symptoms was associated with functional impairment (basic activities of daily living; Barthel index; β = -.04, P = .005).

CONCLUSIONS

Based on a large, population-based longitudinal study, this study underlined the impact of falls on depressive symptoms and consequently extended previous knowledge about an association between falls and depressive symptoms in the oldest old. Developing strategies to prevent falls might also help to prevent depressive symptoms.

The Gender Difference in Depression: Are Elderly Women at Greater Risk for Depression Than Elderly Men?

Numerous epidemiological reports have found that adolescent, young adult, and middle-aged adult girls and women are more likely to be diagnosed with unipolar depression and report greater symptoms of depression when compared to boys and men of similar ages. What is less well-known is whether this gender difference persists into late life. This literature review examines whether the well-known gender difference in unipolar depression continues into old age, and, if it does, whether the variables that are known to contribute to the gender difference in unipolar depression from adolescence through adulthood continue to contribute to the gender difference in the elderly, and/or whether there are new variables that arise in old age and contribute to the gender difference in the elderly. In this review of 85 empirical studies from every continent except for Antarctica, we find substantial support for the gender difference in depression in individuals who are 60 and older. More research is necessary to determine which factors are the strongest predictors of the gender difference in depression in late life, and particularly whether the factors that seem to be responsible for the gender difference in depression in earlier life stages continue to predict the gender difference in the elderly, and/or whether new factors come into play in late life. Longitudinal research, meta-analyses, and model-based investigations of predictors of the gender difference in depression are needed to provide insights into how and why the gender difference in depression persists in older age.

Incidence, risk, and associated factors of depression in adults with physical and sensory disabilities: A nationwide population-based study

BACKGROUND

Physical disability has been associated with the risk of depression. We examined the incidence, risk, and associated factors of depression in Taiwanese adults with physical/sensory disabilities.

METHODS

Two national databases were used to retrospectively analyze 749,491 ≥20-year-old Taiwanese with physical/sensory disabilities in 2002-2008. The incidence of depression was analyzed by univariate Poisson regression. Risk factors of depression were followed up through 2014 and examined with a Cox proportional hazards model.

RESULTS

Among the study subjects, the incidence of depression was 6.29 per 1000 person-years, with 1.83 per 1000 person-years corresponding to major depression. The subjects' depression risk was affected by disability type, disability severity, gender, age, education, marital status, aboriginal status, monthly salary, residence urbanization level, and Charlson comorbidity index (CCI). Subjects with rare diseases, mild disability, female gender, age 35-44 years, a high school education level, divorced/widowed status, non-aboriginal status, a NT$22,801-28,800 monthly salary, a highly urbanized residence area, or a CCI≥3 were at higher risk for depression.

CONCLUSIONS AND IMPLICATIONS

Adults with physical/sensory disabilities have a 3.7-fold higher incidence of depression than the general population. Social services departments and family members should take extra measures toward preventing and treating depression in this subpopulation.

Behavioral and physiological consequences of enrichment loss in rats

Significant loss produces the highest degree of stress and compromised well-being in humans. Current rodent models of stress involve the application of physically or psychologically aversive stimuli, but do not address the concept of loss. We developed a rodent model for significant loss, involving removal of long-term access to a rewarding enriched environment. Our results indicate that removal from environmental enrichment produces a profound behavioral and physiological phenotype with depression-like qualities, including helplessness behavior, hypothalamo-pituitary-adrenocortical axis dysregulation and overeating. Importantly, this enrichment removal phenotype was prevented by antidepressant treatment. Furthermore, the effects of enrichment removal do not occur following relief from chronic stress and are not duplicated by loss of exercise or social contact.
