Anxiety Symptoms in Older Adults with Depression Are Associated with Suicidality

Anger and anxiety in older adults: a cross-lagged examination

OBJECTIVES

Both anger and anxiety are common in older adulthood, with aversive consequences for individuals' physical and mental health. Theory suggests that anger can be an emotional response to the experience of anxiety. Similarly, anger can induce anxiety symptoms. Despite studies documenting the co-occurrence of anger and anxiety and their strong theoretical links, little is known about their temporal relationship. The primary aim of this study was to investigate the longitudinal cross-lagged relationship between anger expression, anger suppression, and anxiety.

METHODS

A large and representative sample of older adults (N=6,852) was utilized, with data collected in two waves at an interval of four years. All variables were measured using validated self-report scales.Data were analyzed using Structural Equation Modeling.

RESULTS

Results indicate that both anger suppression and anger expression are significant predictors of anxiety symptoms. Similarly, anxiety is a significant predictor of both anger suppression and anger expression.

CONCLUSIONS

The effects did not differ in magnitude, suggesting a balanced reciprocity between anger and anxiety. An understanding of this reciprocal association can inform interventions and strategies aimed at promoting emotional well-being in older individuals. By addressing both anger and anxiety concurrently, interventions may have a more comprehensive impact on improving mental health outcomes in this population.

Sleep and Happiness in Urban-Dwelling Older Adults in Ghana: A Serial Multiple Mediation Model of Generalized Anxiety and Depressive Symptoms

OBJECTIVE

Sleep problems (SP) are highly prevalent and seriously affect health and well-being in old age. The aim of this study was to examine the association between SP and happiness in an urban-dwelling older sample. The authors further explore the effects of generalized anxiety and depressive symptoms in the SP-happiness link using serial mediating modeling.

METHODS

Data came from the 2016 to 2018 Aging, Health, Psychological Well-being, and Health-seeking Behavior Study in Ghana (n = 661). The authors measured happiness with the cross-culturally validated item on a five-point scale. The GAD-7 and the CESD-8, respectively, assessed generalized anxiety and depressive symptoms. Participants reported nighttime and daytime SP in the last 30 days. The SPSS-based Hayes' PROCESS macro program (Model 6) was constructed to quantify the hypothesized mediation effect.

RESULTS

The analysis included 661 adults aged greater than or equal to 50 years (mean age = 65.53 [SD] = 11.89 years; 65.20% women). After full adjustment, path models showed that SP was negatively associated with happiness (β = -0.1277, 95%CI = -0.15950 to -0.096). Bootstrapping estimates revealed that the SP-happiness link was serially mediated via generalized anxiety representing 8.77%, depressive symptoms yielding 18.95%, and anxiety symptoms→depressive symptoms accounting for 26.70% of the total effect.

CONCLUSION

Generalized anxiety and depressive symptoms may explain the negative association between SP and happiness in urban-dwelling older adults in the sub-Saharan African (SSA) context. Interventions, social and clinical, to improve happiness through sleep quality should include ways to improve mental health. Longitudinal and cross-cultural data are warranted to assess the bi-directionality of this relationship.

The association between frailty and anxiety: A systematic review

OBJECTIVES

Previous systematic reviews show a clear relationship between frailty and depression, however the association with anxiety is much less frequently explored. Previous single studies indicate evidence is mixed. We completed a systematic review and meta-analysis to identify the relationship between frailty and anxiety.

METHODS

We searched five electronic databases for observational studies in older people in community, care home and outpatient settings with any/no health conditions that measured the association between anxiety and frailty using validated measures. Studies were screened by one reviewer with 10% checked by a second reviewer. The Mixed Methods Appraisal Tool was used to assess study quality. We used meta-analysis to aggregate study findings, with subgroup analyses to explore heterogeneity.

RESULTS

Out of 1272 references, a total of 20 cross-sectional and 1 longitudinal studies were eligible. Older adults with frailty were substantially more likely to display anxiety symptoms than robust populations, across both dichotomous and continuous data sets (n = 10, OR = 3.48, 95% CI: 2.08, 5.81, p < 0.0001, I²  = 94%; N = 5, SMD = 3.13, 95% CI: 1.06, 5.21, I²  = 98%). Similarly, pre-frail older adults were more likely to have anxiety symptoms than robust older adults but to a lesser extent (N = 6, OR = 1.95, 95% CI: 1.41, 2.71, I²  = 63%; N = 3, SMD = 1.70, 95% CI: 0.01, 3.38, I²  = 98%).

CONCLUSIONS

There is a clear association between pre-frailty/frailty and anxiety in older adults. However, data are heterogeneous and primarily from cross-sectional studies so causality cannot be determined. Future research should evaluate the effectiveness of anxiety screening and treatments in frail older adults.

The role of anxiety and depressive symptoms in mediating the relationship between subjective sleep quality and cognitive function among older adults in China

BACKGROUND

Deterioration of cognitive function has a significant impact on the unavoidable burden on individuals, families, and society. This study aimed to examine the serial multiple mediating effects of anxiety and depressive symptoms on the relationship between subjective sleep quality and cognitive function among older adults in China.

METHODS

We selected 6442 Chinese older adults aged 65 years and older from the 2018 Chinese Longitudinal Healthy Longevity Survey. The SPSS PROCESS macro was employed to perform simple and serial multiple mediation analyses.

RESULTS

Subjective sleep quality, depressive symptoms, anxiety symptoms, and cognitive function were significantly related (P < 0.01). Poor sleep quality can have a direct negative influence on cognitive function among older adults (effect = -0.110; 95 % CI = [-0.166, -0.053]), but it can also have an indirect negative impact via three pathways: the independent mediation of anxiety symptoms (effect = -0.028; 95 % CI = [-0.048, -0.011]), the independent mediation of depressive symptoms (effect = -0.014; 95 % CI = [-0.026, -0.002]), and the serial mediation of anxiety and depressive symptoms (effect = -0.009; 95 % CI = [-0.017, -0.001]).

LIMITATIONS

This study used a cross-sectional design, which restricts the ability to infer causal relationships.

CONCLUSIONS

The effect of subjective sleep quality on cognitive function was serially mediated by anxiety and depressive symptoms among older adults. Diverse therapies targeted at improving sleep quality in older adults may improve mood and cognitive functioning.

Associations between anxiety, depression, and risk of suicidal behaviors in Chinese medical college students

Background

Previous studies have established a strong association between depression and suicidal behaviors, yet the relationship between anxiety and suicidal behaviors remains unclear. This study examines whether anxiety and depression are independent risk factors for suicidal behaviors in medical college students, and further, whether anxiety may increase the greater risk of suicidal behaviors (SB) in participants with depression.

Methods

This cross-sectional study was conducted among 4,882 medical students. Demographic information, anxiety, and depression data were collected using online questionnaires or through a widely used social media app named WeChat.

Results

Anxiety and depression were independent risk factors for suicidal behaviors, and levels of risk correlated positively with the severity of both anxiety and depressive symptoms. A dose-response relationship was identified between the severity of anxiety and the risk of SB, as well as the severity of depression and SB. Furthermore, anxiety increased the risk of suicidal behaviors in participants with depression, with a dose-response relationship between the severity of anxiety symptoms and the risk of SB.

Conclusion

The findings highlight the importance of screening for anxiety and depressive symptoms in medical college students, as well as reducing anxiety in addition to depressive symptoms in treatment. This study provides valuable data as a reference for clinicians for suicide risk assessments.

Systematic metabolic characterization of mental disorders reveals age-related metabolic disturbances as potential risk factors for depression in older adults

Mental disorders are associated with dysregulated metabolism, but comprehensive investigations of their metabolic similarities and differences and their clinical relevance are few. Here, based on the plasma metabolome and lipidome of subcohort1, comprising 100 healthy participants, 55 cases with anxiety, 52 persons with depression, and 41 individuals with comorbidity, which are from WCHAT, a perspective cohort study of community-dwelling older adults aged over 50, multiple metabolites as potential risk factors of mental disorders were identified. Furthermore, participants with mental illnesses were classified into three subtypes (S1, S2, and S3) by unsupervised classification with lipidomic data. Among them, S1 showed higher triacylglycerol and lower sphingomyelin, while S2 displayed opposite features. The metabolic profile of S3 was like that of the normal group. Compared with S3, individuals in S1 and S2 had worse quality of life, and suffered more from sleep and cognitive disorders. Notably, an assessment of 6,467 individuals from the WCHAT showed an age-related increase in the incidence of depression. Seventeen depression-related metabolites were significantly correlated with age, which were validated in an independent subcohort2. Collectively, this work highlights the clinical relevance of metabolic perturbation in mental disorders, and age-related metabolic disturbances may be a bridge-linking aging and depressive.

Risk factors for suicidal behaviour in late-life depression: A systematic review

BACKGROUND

Suicide is a leading cause of preventable death worldwide, with its peak of maximum incidence in later life. Depression often puts an individual at higher risk for suicidal behaviour. In turn, depression deserves particular interest in old age due to its high prevalence and dramatic impact on health and wellbeing.

AIM

To gather integrated evidence on the potential risk factors for suicide behaviour development in depressive older adults, and to examine the effects of depression treatment to tackle suicide behaviour in this population.

METHODS

A systematic review of empirical studies, published from 2000 onwards, was conducted. Suicidal behaviour was addressed considering its varying forms (i.e., wish to die, ideation, attempt, and completed suicide).

RESULTS

Thirty-five papers were selected for review, comprising both clinical and epidemiological studies. Most of studies focused on suicidal ideation (60%). The studies consistently pointed out that the risk was related to depressive episode severity, psychiatric comorbidity (anxiety or substance use disorders), poorer health status, and loss of functionality. Reduced social support and loneliness were also associated with suicide behaviour in depressive older adults. Finally, the intervention studies showed that suicidal behaviour was a robust predictor of depression treatment response. Reductions in suicidal ideation were moderated by reductions in risk factors for suicide symptoms.

CONCLUSION

To sum up, common and age-specific risk factors seem to be involved in suicide development in depressive older adults. A major effort should be made to tackle this serious public health concern so as to promote older people to age healthily and well.

Determinants of Suicidal Ideation among Older Adults

Abstract. This study examined the relationship of depression and life satisfaction with suicidal ideation among older Iranian adults. In this cross-sectional study, a total of 159 older adults in Tehran (73% community-residing, 60 years or older) participated. The data were gathered using the Beck Scale for Suicidal Ideation (BSSI), the Geriatric Depression Scale (GDS), and the Life Satisfaction Index-Z (LSIZ). According to the results, depression and life satisfaction are significantly related to suicidal ideation; the two variables predict 0.39% of the variance of suicidal ideation in older adults ( p < .01). The interaction between depression and life satisfaction is a stronger predictor of suicidal ideation in older adults than each of the variables alone.

Mental Disorders, Cognitive Impairment and the Risk of Suicide in Older Adults

More than 600 million people are aged 60 years and over are living in the world. The World Health Organization estimates that this number will double by 2025 to 2 billion older people. Suicide among people over the age of 60 is one of the most acute problems. The factors strongly associated with suicide are mentioned: physical illnesses, such as cancer, neurologic disorder, pain, liver disease, genital disorders, or rheumatoid disorders. Moreover, neurologic conditions, especially stroke, may affect decision-making processes, cognitive capacity, and language deficit. In addition to dementia, the most common mental disorders are mood and anxiety disorders. A common symptom of these disorders in the elderly is cognitive impairment. This study aimed to present the relationship between cognitive impairment due to dementia, mood disorders and anxiety, and an increased risk of suicide among older people. Dementia is a disease where the risk of suicide is significant. Many studies demonstrated that older adults with dementia had an increased risk of suicide death than those without dementia. Similar conclusions apply to prodromal dementia Depression is also a disease with a high risk of suicide. Many researchers found that a higher level of depression was associated with suicide attempts and suicide ideation. Bipolar disorder is the second entity in mood disorders with an increased risk of suicide among the elderly. Apart from suicidal thoughts, bipolar disorder is characterized by high mortality. In the group of anxiety disorders, the most significant risk of suicide occurs when depression is present. In turn, suicide thoughts are more common in social phobia than in other anxiety disorders. Suicide among the elderly is a serious public health problem. There is a positive correlation between mental disorders such as dementia, depression, bipolar disorder, or anxiety and the prevalence of suicide in the elderly. Therefore, the elderly should be comprehensively provided with psychiatric and psychological support.

Comorbid depressive and anxiety symptoms and frailty among older adults: Findings from the West China health and aging trend study

BACKGROUND

Depression and anxiety are two common mental disorders in older people. Studies have reported that depression is strongly associate with frailty, but few studies focus on anxiety disorder and comorbid two mental disorders. In this study, we aimed to identify associations between comorbid depressive and anxiety symptoms with frailty in older adults.

METHODS

4,103 community-dwellings adults aged 60 and older from the baseline of the West China Health and Aging Trend (WCHAT) study were included. Frailty was measured by the Fried frailty phenotype criteria. The 15-item Geriatric Depression Scale (GDS-15) and 7-item Generalized Anxiety Disorder Scale (GAD-7) assessed for depressive and anxiety symptoms with a cut-off value of 5. Multinomial logistic regression was used to explore the association between different depressive and anxiety status and frailty.

RESULTS

8.7% of old adults suffered comorbid depressive and anxiety symptoms in the present study. The prevalence of pre-frailty and frailty was 47.0% and 6.7%, respectively. After adjusting for covariates, individuals with comorbid depressive and anxiety symptoms had higher odds of being pre-frail (OR=1.86, 95% CI=1.41, 2.45) and frail (OR=7.03, 95% CI=4.48, 11.05) compared to those without depressive and anxiety symptoms. In the comorbidity group, those with severe comorbid symptoms also had higher prevalence of pre-frailty and frailty.

LIMITATIONS

Depressive and anxiety symptom assessments were based on screening tools.

CONCLUSIONS

This study suggested comorbid depressive and anxiety symptoms were associated with frailty among Chinese older adults. Further efforts to screen and target depression and anxiety comorbidity may be warranted.

The question of preoperative anxiety and depression in older patients and family protectors

Background

Higher levels of anxiety increase the risks of surgery, including morbidity and mortality. The objectives of this study were to measure anxiety and depression during the preoperative period and to identify the degree of knowledge and concerns of older patients and their family protectors regarding anesthesia, and the causes of these concerns.

Methods

We administered a questionnaire to older patients scheduled to undergo surgery and their family protectors one day prior to the surgery. The questionnaire included tools for quantifying anxiety and depression (Anxiety-Visual Analogue Scale, the Amsterdam Preoperative Anxiety and Information Scale, State-Trait Anxiety Inventory Korean YZ Form, and Short Form Geriatric Depression Scale). We also asked about the concrete causes of anxiety using pre-created forms.

Results

There were 140 older patients and family protectors who participated in the study. The majority of older patients (n = 114, 81.4%) undergoing surgery and their family protectors (n = 114, 81.4%) indicated that they were anxious. Most of the older patients and their family protectors responded that they had insufficient knowledge about anesthesia, and they were mostly worried about failure to awaken following surgery, and postoperative pain. Older patients with higher anxiety scores showed higher depression scores. There were significant differences in depression scores depending on the presence of cohabitating family members.

Conclusions

It is important to remember that older patients with higher depression scores have higher anxiety during the preoperative period.

The effect of anxiety on cognition in older adult inpatients with depression: results from a multicenter observational study

Late-life depression is associated with reduced cognitive function beyond normal age-related cognitive deficits. As comorbid anxiety frequently occur in late-life depression, this study aimed to examine the association between anxiety symptoms and cognitive function among older inpatients treated for depression. We hypothesized that there would be an overall additive effect of comorbid anxiety symptoms on dysfunction across cognitive domains. The study included 142 patients treated for late-life depression in hospital, enrolled in the Prognosis of Depression in the Elderly study. Anxiety symptoms were measured at admission using the anxiety subscale of the Hospital Anxiety and Depression Scale. Patients completed cognitive tasks at admission and discharge. Linear mixed and generalized linear mixed models were estimated to investigate the effect of anxiety, on continuous and categorical cognitive scores, respectively, while controlling for depression. Anxiety severity at admission was not associated with performance in any of the cognitive domains. Patients with more symptoms of anxiety at admission demonstrated a significant improvement in immediate recall during the hospital stay. Patients with a score above cutoff indicating clinically significant symptoms on the anxiety subscale performed better on general cognitive function, as measured by the Mini Mental Status Examination at admission, than those below cutoff for anxiety. In conclusion, comorbid anxiety symptoms had no additive effect on cognitive dysfunction in late-life depression in our sample of inpatients.

Anxiety symptom levels are persistent in older adults with a mental disorder: A 33-month follow-up study

OBJECTIVE

Anxiety symptoms are common in old age and have been suggested as risk factors for development of cognitive impairment and mortality. The objective of the present study was to investigate whether anxiety symptoms among older adults with a mental health diagnosis are persistent, and severity of anxiety predicts cognitive decline and mortality.

METHODS

We collected data from 201 patients referred to specialist mental health service in a department of geriatric psychiatry. Of these, 150 were reexamined after 33 months, while 51 patients died before follow-up. Mean age (SD) at baseline among the patients that were reexamined was 73.4 (7.3) years, and 67% were women. The Geriatric Anxiety Inventory (GAI) was used to measure anxiety symptoms at baseline and follow-up. We investigated whether higher GAI scores at baseline were associated with persistence of anxiety. Associations with cognitive decline or mortality were also explored. The associations were estimated by use of trajectory analysis and regression models.

RESULTS

Seventy-four percentages had the same level of anxiety symptoms, and 29% had a high level of anxiety at baseline and follow-up. GAI score at baseline was not associated with cognitive decline or mortality at 33-month follow-up.

CONCLUSION

In a longitudinal study of anxiety symptoms among older adults in specialist mental health services, we demonstrate persistent high or low levels of anxiety symptoms. Anxiety trajectories over time were not predicted by patient characteristics. Also the level of anxiety cannot be used as predictor for future cognitive decline or mortality in a clinical population.
