A systematic review of physical illness, functional disability, and suicidal behaviour among older adults

Risk of Suicide Across Medical Conditions and the Role of Prior Mental Disorder

Importance

According to the World Health Organization, more than 700 000 individuals worldwide die by suicide each year. Medical conditions likely increase the risk of suicide.

Objective

To (1) provide age- and sex-specific pairwise estimates of the risk of suicide across a comprehensive range of medical conditions, (2) investigate whether there is a dose-response-like relationship at play (ie, the higher the disability burden due to medical morbidity, the higher the risk of suicide), and (3) determine if the risk of suicide with medical conditions is particularly pronounced among those who had mental disorder preceding the medical conditions.

Design, Setting, and Participants

This cohort study was an observational study of population-based data for all individuals living in Denmark at some point between 2000 and 2020. The data analysis took place from September 2023 to May 2024.

Exposures

Thirty-one specific medical conditions as well as prior mental disorder.

Main Outcomes and Measures

The main outcome was suicide. Associations between the 31 specific medical conditions, nested within 9 categories, and suicide were examined via Poisson regression, yielding incidence rate ratios (IRRs). Subsequent analyses included an interaction term to assess whether a previous hospital-treated mental disorder modified the associations. Finally, the association between the disability burden of medical conditions and suicide was examined for those with and without prior mental disorder, respectively.

Results

A total of 6 635 857 individuals (3 337 613 females and 3 298 244 males) were included in the analyses of the associations between medical conditions and suicide. Except for endocrine disorders, all categories of medical conditions were associated with a statistically significant increased risk of suicide (which was most pronounced for gastrointestinal conditions [IRR, 1.7; 95% CI,1.5-1.8], cancer [IRR, 1.5; 95% CI, 1.4-1.6], and hematological conditions [IRR, 1.5; 95% CI, 1.3-1.6]). Interaction between mental disorder and individual medical conditions did not seem to play a major role for suicide risk. For those without but not for those with mental disorder, there was a dose-response-like relationship between the disability burden of medical conditions and suicide.

Conclusions and Relevance

Medical conditions are generally associated with increased risk of suicide in a dose-response-like manner. Individuals with hospital-treated mental disorder appear to be at such elevated risk of suicide that additional disability associated with medical conditions has little impact in this regard.

Risk and protective factors of a wish to die and suicidal ideation in community-dwelling, older, Flemish adults: results of the Belgian ageing studies

OBJECTIVES

This study aims to increase the understanding of suicidality in older adults by investigating the prevalence, characteristics, risk and protective factors of suicidal phenomena in community-dwelling older adults (60+) in Flanders, specifically of a current wish to die (WTD) and lifetime suicidal ideation and behaviour (LSIB).

METHOD

Cross-sectional data from the Belgian Ageing Studies (BAS) is used (N = 3050). The BAS aims to monitor the needs and quality of life of community-dwelling older adults through a standardised survey. Statistical methods used are bivariate analyses and binary logistic regression.

RESULTS

Prevalence rates of 4.8% for WTD and 8.2% for LSIB are found. LSIB is the biggest predictor of a current WTD, followed by requiring support on three domains, elder abuse, depression and subjective cognitive complaints, and elder abuse were significant risk factors for both WTD and LSIB. Limited effects of protective factors were found.

CONCLUSION

Previous research regarding risk factors to be confirmed in this study, and new insights on the effect of elder abuse, subjective indicators of cognitive complaints and requiring support are added. Further research into protective factors and underlying mechanisms is required.

Population-attributable fraction of psychiatric and physical disorders for suicide among older adults in Taiwan

BACKGROUND

This study aimed to estimate the population-attributable fraction (PAF) of psychiatric and physical disorders for suicide among older adults, focusing on sex- and age-specific factors.

METHODS

Data from Taiwan's National Health Insurance Research Data and National Death Registry included 9136 cases of suicide in individuals aged 65+, with 89,439 matched controls. Physical and psychiatric disorders were identified through diagnostic records. Conditional logistic regression assessed risk factors, and PAF was calculated using disorder prevalence and adjusted odds ratios.

RESULTS

Major suicide risk factors among older adults were depressive disorders, anxiety disorders, and sleep disorders. Physical disorders like hypertension, peptic ulcers, and cancer also showed significant PAF values. The combined PAF of physical disorders equaled that of psychiatric disorders. Psychiatric disorders had a greater impact on women and the youngest-old adults, while physical disorders had a higher contribution among men, middle-old adults, and oldest-old adults.

LIMITATIONS

Relying solely on claim data to identify psychiatric and physical disorders may underestimate their prevalence and associations with suicide due to unrecorded cases of individuals not seeking help and the absence of key risk factors like social isolation and family support.

CONCLUSIONS

This study identifies preventable or treatable risk factors for older adult suicide, emphasizing the need to target specific psychiatric and physical disorders in suicide prevention efforts while taking into account sex- and age-specific considerations. It also underscores the importance of establishing social welfare support systems to address the unique challenges older adults face.

Age-stratified risk of suicide in patients with schizophrenia

OBJECTIVES

Schizophrenia is associated with an increased risk of suicide. Few studies have investigated the risk of suicide across different ages, likely due to limitations around sample size.

METHODS

From the National Health Insurance Research Database in Taiwan, this study identified 195,787 patients with schizophrenia from January 1, 2000, to December 31, 2019. During the study period, 3848 patients died from suicide. We calculated the standardized mortality ratio (SMR) for suicide stratified by age. In this age-stratified, nested case-control study, risk set sampling was used to match each case with 4 living controls by age, sex, and the year of the first diagnosis with schizophrenia. Conditional logistic regression was used for estimating age-stratified risk profiles.

RESULTS

The SMR was the highest in the <25 years age group (52.8) and inversely correlated with age. Unemployment was associated with an increased risk of suicide in the 25 to 34, 35 to 44, 45 to 54, and 55 to 64 years age groups. Depressive and sleep disorders before suicide were more common among suicide cases with schizophrenia than among controls across all age groups. Drug-induced and alcohol-induced mental disorders were significantly associated with suicide but were observed only in the age group younger than 54. Heart disease, pneumonia, and moderate or severe renal disease were risk factors for suicide in the age groups less than 65.

CONCLUSIONS

The risk factors for suicide differ by age. This study's findings can be used to optimize health-care interventions for preventing suicide in patients with schizophrenia.

Diligent for better or worse: Conscientiousness is associated with higher likelihood of suicidal behavior and more severe suicidal intent in later life

BACKGROUND

Contradictory findings link trait conscientiousness in mid- and late life to increased healthspan and lifespan, as well as to death by suicide. It remains unclear whether conscientiousness is associated with higher odds of attempting suicide or with more severe suicidal behavior among attempters, and whether its relationship to suicide risk varies with aging-related stressors, such as declining health.

METHODS

In this cross-sectional study comprising 313 depressed adults aged ≥40 years and participating in the Longitudinal Research Program in Late-Life Suicide (Pittsburgh, USA), we employed logistic and linear regression to test whether conscientiousness was associated with the presence of recent suicidal behavior (≤2 years) and with intent severity in recent attempters (n = 84). We further tested whether the above relationships varied based on mental, cognitive, and physical health status, measured as depression severity, cognitive functioning, and the presence/absence of severe physical illness.

RESULTS

Participants were 62.1 years old on average (SD = 7.6), 85% White, and 53% female. Recent attempters had a mean age of 61.8 years at their most recent attempt (SD = 8.5), had lower cognitive functioning and were more likely severely physically ill than comparisons. Conscientiousness was positively associated with a higher likelihood of recent suicidal behavior overall (adjusted OR = 1.44, 95% CI = 1.09, 1.90, p = .010), but not in case of co-occurring severe physical illness (interaction OR = 0.54, 95% CI = 0.30, 0.97, p = .039). Conscientiousness was also positively associated with suicidal intent at the most recent attempt (adjusted β = 1.60, SE = 0.62, p = .012), explaining 7% of its variance, although this association lost significance after adjusting for other personality dimensions.

CONCLUSIONS

Highly conscientious middle-aged and older adults may be at increased risk of resolute suicidal behavior, although conscientiousness may not confer additional suicide risk among those severely physically ill.

Obstructive respiratory disease in U.S. veterans: Prevalence, characteristics, and health burden

OBJECTIVE

To examine the psychiatric and physical health burden of obstructive respiratory disease in a nationally representative sample of U.S. Veterans.

METHODS

Secondary data analyses were conducted using data from the 2019-2020 National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of U.S. Veterans. Participants self-reported health professional-diagnosed obstructive respiratory disease (i.e., asthma, chronic bronchitis or chronic obstructive pulmonary disease). Veterans who reported obstructive respiratory disease (n = 502) were compared to veterans without this disease but with at least one or more other medical conditions-controls (n = 3169) on measures of sociodemographic, trauma, psychiatric, and physical health characteristics. Multivariable regression analyses examined independent associations between obstructive respiratory disease and psychiatric conditions and physical characteristics.

RESULTS

A total 12.5% of the sample reported a diagnosis of obstructive respiratory disease. Compared to controls, veterans with obstructive respiratory disease were more likely to be female, unmarried/partnered, lower income, residing in the Midwest, receiving VA healthcare, and had greater lifetime and childhood trauma burden. In adjusted analyses, veterans with respiratory disease had 47-91% greater odds of screening positive for current posttraumatic stress, major depressive, and generalized anxiety disorders, and had 48% greater odds of current suicide ideation. They were also more likely to have lifetime nicotine use disorder and had more medical comorbidities and more severe somatic symptoms.

CONCLUSIONS

Obstructive respiratory disease is prevalent among U.S. veterans and associated with significant mental and physical health burden. Results highlight the need for timely screening and treatment for psychiatric and medical conditions that are highly comorbid with obstructive respiratory disease in this population.

Sociodemographic and Clinical Characteristics of Older Adults With Suicide-Related Emergency Department Presentations

OBJECTIVES

To identify characteristics of older adult emergency department (ED) patients aged ≥65 with suicidal ideation and/or behavior.

METHODS

A single center retrospective chart review analyzed 392 patients (≥65) with suicidal ideation and/or behavior (2013-2019). Comprehensive full-text searches were used. Subgroup analyses for age and gender were conducted.

RESULTS

Depressive disorder was documented in 50% of cases. Notably, 54% of all women were prescribed antidepressants, compared to only 31% of men. Most patients had general medical conditions (74.5%) and chronic multimorbidity (71.2%). Social stress affected 40.1%; 35.7% were intoxicated upon presentation. Alcohol abuse was more common in the 65-74 age group, while dementia impacted 20% of those ≥75. Men had a six-fold higher 30-day post-discharge mortality.

DISCUSSION

Older ED patients with suicidal ideation and/or behavior exhibit typical characteristics. The dementia prevalence suggests tailored care for those ≥75, and the heightened post-discharge mortality rate in older men requires further research.

Last general practitioner consultation during the final month of life: a national medical record review of suicides in Sweden

OBJECTIVES

Individuals who die by suicide often consult their general practitioners (GPs) in their final weeks of life. The aim of this study was to gain a deeper knowledge of the clinical characteristics and GP assessments and treatments among individuals who consulted their GPs during the month preceding suicide. Further, we compared these features in those with and without contact with psychiatric services (PC and NPC, respectively) during the two years that preceded the suicide.

DESIGN

A nationwide retrospective explorative study investigating medical records.

SETTING

Primary care in Sweden.

PARTICIPANTS

Individuals who died by suicide in Sweden in 2015 with a GP visit within 30 days of death.

RESULTS

The study cohort corresponds to one fifth (n = 238) of all suicides that occurred in Sweden in 2015 (n = 1179), representing all those with available primary care records showing contact with a GP during the final 30 days of life (NPC: n = 125; PC: n = 113). The mean age was 58 years ± 19. Patients in the NPC group were older (NPC: 63 years ± 19 vs. PC: 53 years ± 18, p < 0.0001) and presented psychiatric symptoms less often (NPC: 50% vs. PC: 67%, p < 0.006). Somatic symptoms were as common as psychiatric symptoms for the whole sample, being present in more than half of individuals. Suicide risk was noted in only 6% of all individuals. Referral to psychiatric services occurred in 14%, less commonly for the NPC group (NPC: 6% vs. PC: 22%, p < 0.001). Cardiovascular or respiratory symptoms were noted in 19%, more often in the NPC group (NPC: 30% vs. PC: 6%, p < 0.001), as were diagnoses involving the circulatory system (all 10%, NPC:14% vs. PC: 5%, p < 0.020).

CONCLUSION

A high level of somatic symptoms was observed in primary care patients both with and without psychiatric contact, and this might have influenced GPs' management decisions. Psychiatric symptoms were noted in two thirds of those with psychiatric contact but only half of those without. While GPs noted psychiatric symptoms in over half of all individuals included in the study, they seldom noted suicide risk. These findings highlight the need for increased attention to psychiatric symptoms and suicide risk assessment, particularly among middle-aged and older individuals presenting with somatic symptoms.

STRENGTHS AND LIMITATIONS OF THIS STUDY

The National Cause of Death Register has excellent coverage of suicide deaths and access to medical records was very good. The medical record review provided detailed information regarding primary care utilization before death by suicide. Because of the lack of statistical power, due to the limited number of persons with GP contact during the last month of life, we chose not to correct for multiple comparisons. Our study approach did not capture the reasons behind GPs' documentation of elevated suicide risk. No systematic inter-rater reliability (IRR) testing was made, however, reviewers received training and continuous support from the research group.

Childhood adversity and suicidal ideation in older Korean adults: unraveling the mediating mechanisms of mental health, physical health, and social relationships

BACKGROUND

Suicide rates in older adults are much higher than those in younger age groups. Given the rapid increase in the proportion of older adults in Korea and the high suicide rate of this age group, it is worth investigating the mechanism of suicidal ideation for older adults. Generally, adverse childhood experiences are positively associated with suicidal ideation; however, it is not fully understood what mediating relationships are linked to the association between these experiences and current suicidal ideation.

METHODS

The data from 685 older Korean adults were analyzed utilizing logistic regression, path analyses, and structural equation modeling. Based on our theoretical background and the empirical findings of previous research, we examined three separate models with mental health, physical health, and social relationship mediators. After that, we tested a combined model including all mediators. We also tested another combined model with mediation via mental health moderated by physical health and social relationships.

RESULTS

The univariate logistic regression results indicated that childhood adversity was positively associated with suicidal ideation in older adults. However, multivariate logistic regression results demonstrated that the direct effect of childhood adversity became nonsignificant after accounting all variables. Three path models presented significant mediation by depression and social support in the association between childhood adversity and suicidal ideation. However, combined structural equation models demonstrated that only mediation by a latent variable of mental health problems was statistically significant. Social relationships moderated the path from mental health problems to suicidal ideation.

CONCLUSIONS

Despite several limitations, this study has clinical implications for the development of effective strategies to mitigate suicidal ideation. In particular, effectively screening the exposure to adverse childhood experiences, early identification and treatment of depressive symptoms can play a crucial role in weakening the association between childhood adversity and suicidal ideation in older adults.

A scientometric analysis and visualisation of elderly suicide research from 1951 to 2022

BACKGROUND

There are still many gaps in both national and international literature on elderly suicide. This study aimed to identify the most influential journals in elderly suicide, the countries and authors that contribute the most to the field, and the trends in the field.

MATERIAL AND METHODS

Studies published on elderly suicide between 1951 and 2022 were retrieved utilising the Web of Science Core Collection. Co-authorship analysis of countries and authors, as well as co-occurrence analysis of keywords, were conducted using VOSviewer 1.6.18.

RESULTS

There were 2864 articles retrieved, including 95 countries, 889 academic journals, 9162 authors and 4160 keywords. The number of publications in this field has significantly increased after the 2000s, and the United States is the most productive country (996). The most prolific author is Yeates Conwell, while the journal with the highest number of publications in this field is the International Journal of Geriatric Psychiatry. Other than 'suicide' and 'elderly', the most trending keywords are 'depression', 'primary care', 'treatment', 'antidepressant', 'loneliness', 'quality of life' and 'COVID-19'.

CONCLUSION

There has been an increase in both the thematic diversity and quantity of studies on elderly suicide over time. However, these publications predominantly originate from socioeconomically affluent countries with relatively low suicide rates. While the increasing numbers of publications from developing countries in recent years are promising, there is a greater need for publications from countries with lower socioeconomic status for the prevention or intervention of elderly suicides.

Provider Perspectives on Addressing Firearm Safety with Older Adults in Primary Care

OBJECTIVES

Chronic conditions, including mild cognitive impairment and depression, place older adults at high risk of firearm suicide. Approximately 40% of older adults have access to a firearm, and many do not store their firearms safely. However, firearm counseling occurs infrequently in clinical settings. Using by the Ottawa Decision Support Framework (ODSF) to conceptualize the decisional support needed by patients and their providers to facilitate firearm counseling, we explore provider perspectives on desired resources for addressing firearm safety with older adult patients.

METHODS

From March - August 2022, we conducted 21 semi-structured interviews with primary care providers caring for older adults. We report deductive concepts as well as emergent themes.

RESULTS

Major themes were identified from the three components of the ODSF; decisional needs, decision support and decisional outcomes. Themes included: provider self-efficacy to conduct firearm counseling, clinical workflow considerations, stories for change, patient diagnosis implications, and caregiver involvement.

CONCLUSIONS

There is a need for decision aids in the clinical setting that facilitate firearm counseling and promotes shared decision-making about firearm storage.

CLINICAL IMPLICATIONS

Implementing a decision aid in the clinical setting can improve provider self-efficacy to conduct firearm counseling and help reduce risk factors associated with firearm-related harm among older adults.

Psychological Factors Protecting Against Suicidality in Older Adults: A Systematic Review

OBJECTIVE

Suicide rates in older adults are often the highest of any age group, particularly among high income countries. However, there is a limited understanding of the factors that could protect against suicidality in older age. This systematic review aimed to identify and evaluate the psychological factors that protect against suicidality in older age.

METHOD

An a priori protocol was established and registered on PROSPERO (CRD42022343694). EMBASE, MEDLINE, PsycINFO, Web of Science and Scopus were searched. Papers were quality assessed using the Quality Assessment with Diverse Studies (QuADSs) tool. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Seventeen papers were included and narratively synthesised.

RESULTS

The initial searches identified 10,673 records, resulting in the screening of 5441 records after the removal of duplicates. The protective factors identified were (1) meaning/purpose in life, (2) reasons for living, (3) coping styles, (4) psychological wellbeing, (5) life satisfaction, (6) personality factors, (7) cognitive functioning, and (8) sense of belonging. The factors with the most empirical support were meaning in life, followed by psychological wellbeing and coping responses, such as primary control strategies, and personality traits, such as positive affect and agency. There was also evidence to suggest that the influence of some protective factors, for example meaning in life, may depend upon stage in older life and gender.

CONCLUSION

This review identified several psychological factors that have been found to protect against suicidal ideation in older adults, representing potential treatment targets for reducing suicide in older adults. Recommendations for future research includes greater use of longitudinal and case-control designs, measuring outcomes across the continuum of suicidality and using samples that allow comparison between younger and older adults and within the spectrum of old age.

Anxiety symptoms preceding suicide: A Swedish nationwide record review

BACKGROUND

The literature on the relationship between anxiety and suicidal behaviors is limited and findings are mixed. This study sought to determine whether physicians noted anxiety symptoms and suicidality in their patients in the weeks and months before suicide.

METHODS

Data were derived from a nationwide medical record review of confirmed suicides in Sweden in 2015. Individuals with at least one documented physician consultation in any health care setting during 12 months before suicide (N = 956) were included. Clinical characteristics were compared between decedents with and without a notation of anxiety symptoms. Odds ratios were calculated to estimate associations between anxiety symptoms and suicidality in relation to suicide proximity.

RESULTS

Anxiety symptoms were noted in half of individuals 1 week before suicide. Patients with anxiety were characterized by high rates of depressive symptoms, ongoing substance use issues, sleeping difficulties, and fatigue. After adjustment for mood disorders, the odds of having a notation of elevated suicide risk 1 week before death were doubled in persons with anxiety symptoms. Associations were similar across time periods (12 months - 1 week). Two-thirds had been prescribed antidepressants at time of death.

LIMITATIONS

Data were based on physicians' notations which likely resulted in underreporting of anxiety depending on medical specialty. Records were not available for all decedents.

CONCLUSIONS

Anxiety symptoms were common in the final week before suicide and were accompanied by increases in documented elevated suicide risk. Our findings can inform psychiatrists, non-psychiatric specialists, and GPs who meet and assess persons with anxiety symptoms.

Chinese older adults' prior-to-death disability profiles and their correlates

BACKGROUND

Disability prior to death complicates end-of-life care. The present study aimed to explore the prior-to-death disability profiles of Chinese older adults, the profiles' links to end-of-life care arrangements and place of death, and predictors of the profiles.

METHODS

In total, data were extracted from the records of 10,529 deceased individuals from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Latent profile analyses, bivariate analysis, and multivariate logistic regression were applied to identify prior-to-death disability profiles, explore the profiles' links to end-of-life care arrangements and place of death, and examine predictors in the profiles, respectively.

RESULTS

Three prior-to-death disability profiles, namely, Disabled-Incontinent (37.6%), Disabled-Continent (34.6%), and Independent (27.8%), were identified. Those with the Independent profile were more likely to live alone or with a spouse and receive no care or care only from the spouse before death. Disabled-Continent older adults had a higher chance of dying at home. Being female, not "married and living with a spouse", suffering from hypertension, diabetes, stroke or cerebrovascular disease (CVD), bronchitis/emphysema/pneumonia, cancer, or dementia, and dying in a later year were associated with more severe prior-to-death disability patterns. Not having public old-age insurance predicted lower chances of having a Disabled-Incontinent profile, and advanced age increased the chance of having a Disabled-Continent profile.

CONCLUSIONS

Three prior-to-death disability patterns were identified for Chinese adults aged 65 years and older. These profiles were significantly linked with the end-of-life caregiving arrangements and place of death among older adults. Both demographic information and health status predicted prior-to-death disability profiles.

Depressive Symptoms in Caregivers of Hospice Cancer Patients

Objectives: Family members and close friends provide countless hours of care for patients enrolled in hospice care. They do so without pay, often sacrificing their own financial well-being and health in the process. This study asks 4 research questions: (1) What is the prevalence and severity of depressive symptoms among caregivers of hospice cancer patients? (2) What demographic and contextual factors (such as relationship with patient) are related to the severity of depressive symptoms among caregivers of hospice cancer patients? (3) Are caregiver quality of life and caregiver burden associated with depressive symptoms? and (4) Is baseline depression associated with change in depression over time? Methods: This was a secondary analysis of data collected in a cluster randomized controlled trial. Results: Thirty-five percent of caregivers reported depressive symptoms of moderate or greater severity. These depressive symptoms were found to increase depending on the relationship of the caregiver to the patient. Caregivers with higher reported burden and lower reported quality of life were also found to have higher depressive symptoms. Significance of Results: Hospice agencies are encouraged to assess caregiver depressive symptoms and have protocols in place to assist caregivers with high depressive symptoms.

Analysis of health services use and clinical profiles in the year prior to suicide between 2010 and 2018: An opportunity to improve its prevention

INTRODUCTION

Suicide is the first cause of external death in Spain. International studies show frequent and varied health contacts in the months prior to suicide. There are hardly any studies on that phenomenon in this country.

OBJECTIVE

To analyze health care use in the year prior to suicide between 2010 and 2018 in the Basque Country, as well as pharmacological prescriptions and psychiatric diagnoses received.

METHODS

Retrospective descriptive study with all suicides registered by the Basque Institute of Legal Medicine (BILM) between 2010 and 2018. The records of the BILM and the Basque Health Service (Osakidetza) were cross-checked.

RESULTS

1526 suicides were analyzed. 74% had health contacts in the previous year. The use was higher in women (p<0.05) and in older ages (p<0001). Primary care was the most used specialty (58.8% the previous year and 7.1% the previous week), followed by Hospital Emergencies (50.3% and 10.2%) and Outpatient Medical Specialties (49% and 11.6%), especially Radiology. Outpatient psychiatry only contacted 29.6% that year, although it had the highest average number of visits (15.1 SD22.6). The most frequent diagnostic category among psychiatric patients was F30-39 (26.7%), with differences between sexes and ages. 49.7% received psychotropic drugs.

CONCLUSIONS

The results are aligned with international evidence, which they also extend, and reinforce the need to extend prevention beyond psychiatric services. It seems advisable to increase proactivity in the search for risk by sensitizing and training different professional profiles, but also to work from non-health settings to improve assistance to highly vulnerable profiles (young men) with low health links.

A narrative review: suicide and suicidal behaviour in older adults

Globally, suicide is a public health concern that claims the lives of many each year. The complex etiology and factors contributing to the risk of suicide make it hard to predict the likelihood of death by suicide. Suicide rates have been increasing over the past 25 years in patients aged 65 years and older, and with the expected increases in the size of the older adult population and the under-detection of suicide risk, these rates may continue to increase. To mitigate and attempt to limit this expected increase, it is important to understand the risk and protective factors of suicide in older adults. This narrative review focuses on individuals above the age of 65 and encompasses relevant peer-reviewed publications from the past 25 years to cover fatal and non-fatal suicidal behaviour. It summarizes several important risk factors for suicide and suicidal behaviors while considering how risk can be detected, assessed, prevented, and mitigated. Screening methods to detect suicide and depression in older adults were examined based on their effectiveness and suitability for use in this population. Lastly, the impacts of the COVID-19 pandemic on suicide rates in older adults were described.

Older adults coping with critical life events - results of the revised demoralization scale in a representative sample of older adulthood

Background

High suicide rates in older adults are a relevant public health concern. Social isolation or widowhood as well as physical decline play a crucial role for suicidality in older adulthood. Previous evidence suggested that demoralization is an important risk factor for suicide. Whether demoralization is a relevant phenomenon in older adulthood which possibly could account for high suicide rates remains unclear.

Methods

Demoralization Scale II (DS-II) scores assessed in a survey of the German general population were investigated with respect to older adults (aged ≥ 65 years). DS-II scores were compared between older (≥ 65 years) and younger (< 65 years) adulthood and between young-old (65-74y), middle-old (75-84y), and old-old (85+y) individuals. We tested the impact of sociodemographic factors on DS-II scores within older adults.

Results

The sample comprised N = 545 adults ≥ 65 years and N = 1922 adults < 65 years. DS-II scores increased in older compared to younger adults (F(1,2465) = 6.1; p = 0.013; d = 0.09) and further from young-old to old-old (Mdiff = 2.7; 95% CI 0.45, 5.46; p = 0.034). One-fourth of individuals ≥ 65 years and almost half of old-old individuals reported DS-II scores above the cut-off > 5. Living with a partner protected from demoralization in old-old individuals.

Discussion

This study provides first evidence for an increased rate of demoralization in very old adults, in particular women, which is partly related to partnership status. We suggest that demoralization is considered as a crucial entity in older adulthood which can be missed by standard psychological screenings.

Depression in older women who died by suicide: associations with other suicide contributors and suicide methods

Suicides among older women have received little research attention. In this study based on the 2017-2019 National Violent Death Reporting System data, we examined the prevalence of depression in older female suicide decedents (N = 3,061), associations between depression and other suicide precipitants, and the associations between suicide methods and depression. Descriptive statistics and generalized linear models (GLM) for a Poisson distribution with a log link were used to examine the research questions. Of the decedents, 15.0% had depressed mood without a reported diagnosis and 41.8% had a depression diagnosis. Nearly one-half of the decedents with reported depression were receiving mental health/substance use treatment at the time of injury. The likelihood of depression was lower among those who were age 85 and older compared to those were age 65-74, but higher among those who had anxiety disorder (IRR = 1.50, 95% CI = 1.33-1.69), history of suicidal ideation (IRR = 1.22, 95% CI = 1.10-1.35), history of suicide attempt (IRR = 1.27, 95% CI = 1.14-1.41), and bereavement problems (IRR = 1.45, 95% CI = 1.27-1.65). Those who had depression were less likely to have used firearms (IRR = 0.85, 95% CI = 0.75-0.97) but more likely to have used hanging/suffocation (IRR = 1.37, 95% CI = 1.13-1.67). The findings show that gun ownership was likely an important factor for firearm use. The high prevalence of depressed mood and/or depression diagnosis among older female suicide decedents at the time of their fatal injury underscores the importance of assessing depression and providing evidence-based depression treatment as an essential suicide prevention approach.

A systematic review of psychosocial protective factors against suicide and suicidality among older adults

BACKGROUND

Research on suicide rarely focuses on protective factors. The goal of this systematic review was to assess the evidence of the associations between protective factors and reduced suicidality among older adults.

METHOD

First, a scoping review was conducted to identify pertinent terms that refer to various protective factors against suicidality. A systematic review, following the PRISMA guidelines, was then conducted on a selection of 15 protective factors (e.g., perceived control, well-being and quality of life, life satisfaction, purpose-in-life, resilience, coping, religiosity, hope, self-regulation, sense of belonging, mattering, positive relationship, social support, social connectedness, and social participation), with separate searches performed on each factor in five databases. Empirical studies were eligible if participants were adults aged 60 years and over, and if the studies reported predictive statistical analysis.

RESULTS

A total of 70 studies were retained for the review. Suicidal ideation was the main outcome measure (91%). Significant associations were consistently observed between all protective factors and reduced suicidal ideations or behaviors, particularly for purpose-in-life, resilience, and positive relationships, indicating that these are solid components for suicide prevention. Using scales, instead of a single item, to measure protective factors (e.g. life satisfaction) was more efficient to capture the associations. On the other hand, results were similar whether studies used subjective (e.g., sense of belonging) or objective (e.g., social connectedness) measures.

CONCLUSION

Protective factors were inversely associated with suicidal ideation. Improving protective factors is essential for the development of late-life suicide prevention and interventions, instead of merely focusing on risk factors.

Exploring community mental health service use following hospital-treated intentional self-harm among older Australians: a survival analysis

OBJECTIVES

This study aimed to examine the impact of community mental health (CMH) care following index hospital-treated intentional self-harm (ISH) on all-cause mortality. A secondary aim was to describe patterns of CMH care surrounding index hospital-treated ISH.

DESIGN

A longitudinal whole-of-population record linkage study was conducted (2014-2019), with index ISH hospitalization (Emergency Department and/or hospital admissions) linked to all available hospital, deaths/cause of death, and CMH data.

SETTING

Australia's most populous state, New South Wales (NSW) comprised approximately 7.7 million people during the study period. CMH services are provided statewide, to assess and treat non-admitted patients, including post-discharge review.

PARTICIPANTS

Individuals with an index hospital presentation in NSW of ISH during the study period, aged 45 years or older.

INTERVENTION

CMH care within 14 days from index, versus not.

MEASUREMENTS

Cox-proportionate hazards regression analysis evaluated all-cause mortality risk, adjusted for relevant covariates.

RESULTS

Totally, 24,544 persons aged 45 years or older experienced a nonfatal hospital-treated ISH diagnosis between 2014 and 2019. CMH care was received by 56% within 14 days from index. Survival analysis demonstrated this was associated with 34% lower risk of death, adjusted for age, sex, marital status, index diagnosis, and 14-day hospital readmission (HR 0.66, 95% CI 0.58, 0.74, p < 0.001). Older males and chronic injury conveyed significantly greater risk of death overall.

CONCLUSIONS

CMH care within 14 days of index presentation for self-harm may reduce the risk of all-cause mortality. Greater effort is needed to engage older males presenting for self-harm in ongoing community mental health care.

Suicidal Ideation in Canadian Family Caregivers for a Person with Dementia: A Portrait of the Situation

This study aimed to explore the prevalence of suicidal thoughts and potential associations (i.e., strength and direction) with caregiver characteristics or factors. A targeted survey was distributed to dementia caregivers aged 55+ years. Questions concerning psychological distress, suicidal thoughts while caregiving and antecedents of suicidal behaviours were administered. A sample of 71 French-speaking Canadian caregivers completed the survey between May and October 2019. Among them, 52.1 per cent (n = 37) reported suicidal ideation while providing care to a relative or a friend living with dementia. Caregivers who presented suicidal ideation reported more abusive behaviour toward the care recipient. Caregivers who reported suicidal thoughts were significantly more distressed than caregivers without them on measures of burden, depression, and anxiety. Suicidal thoughts in caregivers are important evaluation targets, primarily for the prevention of suicide, but also because caregivers who report suicidal thoughts also present a heightened risk for abusing the care recipient.

The characteristics of elderly suicidal attempters in the emergency department in Korea: a retrospective study

BACKGROUND

Although Korea ranks first in the suicide rate of elderly individuals, there is limited research on those who attempt suicide, with preventive measures largely based on population-based studies. We compared the demographic and clinical characteristics of elderly individuals who attempted suicide with those of younger adults who visited the emergency department after suicide attempts and identified the factors associated with lethality in the former group.

METHODS

Individuals who visited the emergency department after a suicide attempt from April 1, 2017, to January 31, 2020, were included. Participants were classified into two groups according to age (elderly, ≥65 years; adult, 18-64 years). Among the 779 adult patients, 123 were elderly. We conducted a chi-square test to compare the demographic and clinical features between these groups and a logistic regression analysis to identify the risk factors for lethality in the elderly group.

RESULTS

Most elderly participants were men, with no prior psychiatric history or suicide attempts, and had a higher prevalence of underlying medical conditions and attributed their attempts to physical illnesses. Being sober and planning suicide occurred more frequently in this group. In the elderly group, factors that increased the mortality rate were biological male sex (p<0.05), being accompanied by family members (p<0.05), and poisoning as a suicide method (p<0.01).

CONCLUSION

Suicide attempts in elderly individuals have different characteristics from those in younger adults and are associated with physical illness. Suicides in the former group are unpredictable, deliberate, and fatal. Therefore, tailored prevention and intervention strategies addressing the characteristics of those who are elderly and attempt suicide are required.

Late life anxiety and depression symptoms, and suicidal behaviors in racial/ethnic minority older adults in community-based organizations and community clinics in the U.S

OBJECTIVE

Late life anxiety and depression represent a significant source of disability, with racial/ethnic minority older adults in the U.S. showing marked disparities in healthy aging. Community-based organizations (CBOs) and community clinics serve these populations for preventive care, yet few identify their mental health service needs. We examine the association between race/ethnicity and risk of mild-to-severe symptoms of anxiety and depression, and suicidal behaviors in minority older adults.

METHOD

Data come from the multisite randomized controlled trial Building Community Capacity for Disability Prevention for Minority Elders, which screened 1,057 adults (45.5% Asian, 26.8% Latinx, 15.0% non-Latinx Black, 8.5% non-Latinx White, and 4.2% American Indian) aged 60 + years at CBOs and clinics in Massachusetts, New York, Florida, and Puerto Rico. Screened participants completed the Generalized Anxiety Disorder-7 (GAD-7) for anxiety symptoms, the Geriatric Depression Scale-15 (GDS-15) for depression symptoms, and the Paykel Suicide Risk Questionnaire for suicidal behaviors.

RESULTS

28.1% of older adults reported mild-to-severe anxiety symptoms, 30.1% reported mild-to-severe depression symptoms, and 4.3% reported at least one suicidal behavior. Compared to non-Latinx Whites, Latinxs had higher odds of mild-to-severe anxiety and depression symptoms and one or more suicidal behaviors, and Asians had higher odds of mild-to-severe depression symptoms only.

CONCLUSIONS

There is an urgent need to improve outreach for screening and preventive mental health care for minority older adults. Expanding outreach and community-based capacity to identify and treat minority older adults with mental health conditions represents an opportunity to prevent disability.

Risk Factors for Suicide in Men

Suicide and the risk factors associated with it have been researched with increasing interest over the last 5 decades with respect to socioeconomic status, age, geographic location, and ethnic background. There has been less focus related to the risk factors specific to gender and how to incorporate clinical screening and interventions to reduce the mortality of suicide in males. With men accounting for a disproportionate number of deaths from suicide in the United States and worldwide, how gender could impact suicidal behavior and ideations remains a topic understudied and with great potential for significant improvement in clinical recognition and treatment.

Factors associated with depression and suicidal ideation among oldest-old adults aged 85 years or older based on gender, using the survey data of South Korea

BACKGROUND

South Korea is predicted to become a superaged society around 2025. Depression in older adults is a major factor influencing suicide. South Korea exhibits the highest suicide rate among the Organization for Economic Co-operation and Development countries.

METHODS

This study aimed to examine the factors associated with depression and suicidal ideation among individuals aged 85 years or older based on gender. Data were obtained from the Korea Institute for Health and Social Affairs, 2017. Overall, 768 individuals aged ≥85 years were included in the final analysis. The participants' general, health-related, and social characteristics were analyzed as factors influencing depression and suicidal ideation.

RESULTS

Among male oldest-old adults, living arrangements and the number of chronic diseases were factors affecting depression, while activities of daily living restrictions and the number of chronic diseases were factors affecting suicidal ideation. Among female oldest-old adults, only the number of chronic diseases affected depression, while financial status and the number of chronic diseases were the factors affecting suicidal ideation.

CONCLUSIONS

The healthcare and welfare services for older adults must be expanded to cater to oldest-old adults who live alone, have activities of daily living restrictions, and have lower financial status. Additionally, the oldest age group's psychological health must be monitored regularly for depression and suicidal ideation to implement active interventions for this high-risk group.

Social reward processing in depressed and healthy individuals across the lifespan: A systematic review and a preliminary coordinate-based meta-analysis of fMRI studies

BACKGROUND

Social rewards (e.g., social feedback, praise, and social interactions) are fundamental to social learning and relationships across the life span. Exposure to social rewards is linked to activation in key brain regions, that are impaired in major depression. This is the first summary of neuroimaging literature on social reward processing in depressed and healthy individuals.

METHOD

We screened 409 studies and identified 25 investigating task-based fMRI activation during exposure to social stimuli in depressed and healthy populations across the lifespan. We conducted a systematic review followed by an Activation Likelihood Estimation (ALE) analysis of three main contrasts: a) positive social feedback vs. neutral stimuli; b) negative social feedback vs. neutral stimuli; c) positive vs. negative social feedback. We also compared activation patterns in depressed versus healthy controls.

RESULTS

Systematic review revealed that social rewards elicit increased activation in subcortical reward regions (NAcc, amygdala, ventral striatum, thalamus) in healthy and depressed individuals; and decreased activation in prefrontal reward regions (medial prefrontal cortex, orbitofrontal cortex) among depressed persons. Our meta-analysis showed, in both depressed and healthy individuals, increased cluster activation of the putamen and caudate in response to negative social stimuli vs. positive stimuli. We also found increased cluster activation in the inferior frontal gyrus (IFG) and the medial frontal gyrus (MFG) in healthy controls vs. depressed individuals, in response to negative social stimuli.

CONCLUSIONS

Processing of social stimuli elicits activation of key brain regions involved in affective and social information processing. Interventions for depression can increase social reward responsivity to improve outcomes.

Understanding the Factors Contributing to Suicide Among the Geriatric Population: A Narrative Review

A critical health concern for older adults is suicide, particularly for those above the age of 60 years. Despite this, research on suicide in this age group is relatively scarce compared to studies on younger populations. This article is intended to summarize the existing literature on etiological/risk factors, including problems with one's physical and mental health, social isolation, money, and life changes like retirement and the death of a spouse and methods for preventing suicide specific to the geriatric population. We conducted a comprehensive literature search to identify the original reports and reviewed publications through various databases, including Google Scholar, PubMed, and the CDC. We gathered information on Google from reputable sources such as the WHO and the National Crime Records Bureau (NCRB). Our review found that the risk factor of suicide in the geriatric population includes physical illness, familial issues, financial issues, and hopelessness. The suicide rate for older adults declined, dropping from 16.17 per 100,000 individuals to 14.25 per 100,000 individuals aged 50 to 69 years and from 27.45 per 100,000 individuals to 24.53 per 100,000 individuals for those over 70 years. A more significant proportion of elderly suicide attempters come from rural than urban locations. Young individuals have better professional opportunities in urban areas, but older people are dispersed to underdeveloped or rural areas, where they are more likely to experience social isolation. By systematically identifying these risk factors, we can develop prevention and intervention strategies to decrease the suicide rates among the geriatric population.

Use of Psychoactive Medications and Risk of Suicide in Late Life (75+): A Total Population Study

BACKGROUND

Psychoactive medications play an important role for the mental health and risk of suicidal behaviour in the oldest segment of the population (75+). A better understanding of psychoactive medication use is advocated to prevent suicide in this age group.

PURPOSE

We investigated the risk of suicide associated with the use of psychoactive medications in the total population aged ≥ 75 years, with and without exposure to antidepressants.

METHOD

A national population-based register study, including all Swedish residents aged ≥ 75 years between 2006 and 2014 (N = 1,413,806). A nested case-control design was used to investigate psychoactive medications associated with suicide among users and non-users of antidepressants. Risk estimates were calculated in adjusted conditional logistic regression models for the entire cohort and by gender.

RESULTS

Suicide occurred in 1305 persons (907 men and 398 women). Among them, 555 (42.5%) were on an antidepressant at the time of suicide. Adjusted incidence rate ratio (aIRR) for suicide was increased in those who were on hypnotics in the total cohort (aIRR 2.05, 95% confidence interval 1.74 to 2.41), in both users and non-users of antidepressants and for both genders. Elevated suicide risk was observed in those who concomitantly used anxiolytics with antidepressants (1.51, 1.25 to 1.83). Decreased risk of suicide was observed among those who were on anti-dementia drugs, in the total cohort (0.33, 0.21 to 0.52) and in both users and non-users of antidepressants. Use of antipsychotics and mood stabilisers showed no effect on suicide risk.

CONCLUSION

Use of hypnotics and concomitant use of anxiolytics with antidepressants was associated with increased risk of late-life suicide. Our findings suggest the need for careful evaluation of the benefit-risk balance of psychoactive medications as well as their availability as a possible suicide means. Future research should consider the indication of use of the psychoactive medications and the severity of psychiatric and medical illnesses of the patients.

Healthcare visits for mental disorders and use of psychotropic medications before and after self-harm in a cohort aged 75

OBJECTIVES

Non-fatal self-harm (SH) is a major risk factor for late-life suicide. A better knowledge of the clinical management of older adults who self-harm is needed to establish where improvements could be made for the implementation of effective suicide prevention interventions. We therefore assessed contacts with primary and specialised care for mental disorders and psychotropic drug use during the year before and after a late-life non-fatal SH episode.

METHOD

Longitudinal population-based study in adults aged ≥75 years with SH episode between 2007 and 2015 retrieved from the regional database VEGA. Healthcare contacts for mental disorders and psychotropic use were assessed during the year before and after the index SH episode.

RESULTS

There were 659 older adults who self-harmed. During the year before SH, 33.7% had primary care contacts with a mental disorder, 27.8% had such contacts in specialised care. Use of specialised care increased sharply after the SH, reaching a maximum of 68.9%, but this figure dropped to 19.5% by the end of the year. Use of antidepressants increased from 41% before to 60% after the SH episode. Use of hypnotics was extensive before and after SH (60%). Psychotherapy was rare in both primary and specialised care.

CONCLUSION

The use of specialised care for mental disorders and antidepressant prescribing increased after SH. The drop in long-term healthcare visits should be further explored to align primary and specialised healthcare to the needs of older adults who self-harmed. The psychosocial support of older adults with common mental disorders needs to be strengthened.

Chronic traumatic encephalopathy neuropathologic change is uncommon in men who played amateur American football

Introduction

We examined postmortem brain tissue from men, over the age of 50, for chronic traumatic encephalopathy neuropathologic change (CTE-NC). We hypothesized that (i) a small percentage would have CTE-NC, (ii) those who played American football during their youth would be more likely to have CTE-NC than those who did not play contact or collision sports, and (iii) there would be no association between CTE-NC and suicide as a manner of death.

Methods

Brain tissue from 186 men and accompanying clinical information were obtained from the Lieber Institute for Brain Development. Manner of death was determined by a board-certified forensic pathologist. Information was obtained from next of kin telephone interviews, including medical, social, demographic, family, and psychiatric history. The 2016 and 2021 consensus definitions were used for CTE-NC. Two authors screened all cases, using liberal criteria for identifying "possible" CTE-NC, and five authors examined the 15 selected cases.

Results

The median age at the time of death was 65 years (interquartile range = 57-75; range = 50-96). There were 25.8% with a history of playing American football and 36.0% who had suicide as their manner of death. No case was rated as definitively having "features" of CTE-NC by all five authors. Ten cases were rated as having features of CTE-NC by three or more authors (5.4% of the sample), including 8.3% of those with a personal history of playing American football and 3.9% of those who did not play contact or collision sports. Of those with mood disorders during life, 5.5% had features of CTE-NC compared to 6.0% of those who did not have a reported mood disorder. Of those with suicide as a manner of death, 6.0% had features of CTE-NC compared to 5.0% of those who did not have suicide as a manner of death.

Discussion

We did not identify a single definitive case of CTE-NC, from the perspective of all raters, and only 5.4% of cases were identified as having possible features of CTE-NC by some raters. CTE-NC was very uncommon in men who played amateur American football, those with mood disorders during life, and those with suicide as a manner of death.

Gone Too Soon: priorities for action to prevent premature mortality associated with mental illness and mental distress

Globally, too many people die prematurely from suicide and the physical comorbidities associated with mental illness and mental distress. The purpose of this Review is to mobilise the translation of evidence into prioritised actions that reduce this inequity. The mental health research charity, MQ Mental Health Research, convened an international panel that used roadmapping methods and review evidence to identify key factors, mechanisms, and solutions for premature mortality across the social-ecological system. We identified 12 key overarching risk factors and mechanisms, with more commonalities than differences across the suicide and physical comorbidities domains. We also identified 18 actionable solutions across three organising principles: the integration of mental and physical health care; the prioritisation of prevention while strengthening treatment; and the optimisation of intervention synergies across social-ecological levels and the intervention cycle. These solutions included accessible, integrated high-quality primary care; early life, workplace, and community-based interventions co-designed by the people they should serve; decriminalisation of suicide and restriction of access to lethal means; stigma reduction; reduction of income, gender, and racial inequality; and increased investment. The time to act is now, to rebuild health-care systems, leverage changes in funding landscapes, and address the effects of stigma, discrimination, marginalisation, gender violence, and victimisation.

Suicidality and Its Association with Stigma in Clinically Stable Patients with Schizophrenia in Rural China

Purpose

Patients with schizophrenia not only experience more stigma than those with other mental illnesses, but they also have a higher risk of committing suicide. There are, however, few research on the connection between rural individuals with clinically stable schizophrenia and suicidality when they feel stigmatized. Therefore, the purpose of this study was to look at the suicidality in clinically stable patients with schizophrenia in rural China, including the prevalence, clinical correlates, and its relationships with stigma.

Patients and Methods

From September 2022 to October 2022, we conducted a multicenter, cross-sectional study in rural Chaohu, Anhui Province, China, and A total of 821 patients with schizophrenia completed the assessment. Three standardized questions were used to assess suicidality (including suicidal ideation, suicide plan, and suicide attempt), Patient Health Questionnaire with 9 items (PHQ-9) for determining depressive state, the first two items of the World Health Organization Quality of Life Questionnaire-Brief Version (QOL), which measures quality of life, the Social Impact Scale (SIS) to assess stigma, and some other important variables (eg employment, psychiatric medication, etc.) were measured using a homemade scale.

Results

Of the 821 participants who completed the questionnaire, 19.2% of the patients were found to have suicidality, of which 19.2% (158/821) were suicidal ideation, 5.6% (46/821) were suicide plans and 4.5% (37/821) were suicide attempts. Binary logistic regression analysis showed that job status (OR=0.520, p=0.047), psychiatric medication (OR=2.353, p=0.020), number of hospitalizations (OR=1.047, p=0.042), quality of life (OR=0.829, p=0.027), PHQ-9 (OR=0.209, p<0.001) stigma (OR=1.060, p<0.001) and social isolation in stigma (OR=1.134, p=0.001) were associated independently with suicidality.

Conclusion

Among clinically stable schizophrenia patients in rural China, suicidality is frequent and associated with stigma. Since stigma and some risk factors have a negative impact on suicidality, we should conduct routine screening and take suicide prevention measures to clinically stable schizophrenia patients in rural areas of China.

Is the combination of depression symptoms and multimorbidity associated with the increase of the prevalence of functional disabilities in Brazilian older adults? A cross-sectional study

Introduction: Functional disabilities are more prevalent in older adults with multimorbidity and depression. However, few studies have investigated the combination of multimorbidity and depression with functional disability. This study aims to verify whether symptoms of depression and multimorbidity combined increase the prevalence of functional disability in Brazilian older adults. Material and methods: This is a cross-sectional study conducted with data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) baseline examination in 2015-2016 in adults aged 50 years and older. The variables included were basic (BADL) and instrumental activities of daily living (IADL), depressive symptoms, multimorbidity (≥2 chronic diseases), sociodemographic variables, and lifestyle. Logistic regression was performed to estimate crude and adjusted odds ratios. Results: A total of 7,842 participants over 50 years of age were included. Of these, 53.5% were women and 50.5% were between 50 and 59 years old, 33.5% reported ≥4 depressive symptoms, 51.4% had multimorbidity, 13.5% reported difficulty in performing at least one BADL, and 45.1% reported difficulty in performing the IADL. In the adjusted analysis, the prevalence of difficulty on BADL was 6.52 (95% CI: 5.14; 8.27) and on IADL was 2.34 (95% CI: 2.15; 2.55), higher for those with depression and multimorbidity combined when compared with those without these conditions. Conclusion: The combination of symptoms of depression and multimorbidity may increase functional impairments in the BADL and IADL of Brazilian older adults, impairing self-efficacy, independence, and autonomy. Early detection of these factors benefits the person, their family, and the healthcare system for health promotion and disease prevention.

Built Environment Accessibility and Disability as Predictors of Well-Being among Older Adults: A Norwegian Cross-Sectional Study

Knowledge about the influence environmental factors have on well-being is important to deliver policies supporting healthy ageing and sustainable health equity. An under-researched question is whether and how the built environment plays a role on well-being among older adults with disabilities. This study explores the relationship between built environment accessibility and disability on psychosocial well-being among older adults. Data were used from the Norwegian Counties Public Health Survey collected during February 2021 in Møre and Romsdal county (N = 8274; age = 60-97, mean = 68.6). General linear modelling was performed to examine the relationship and interaction between built environment accessibility (services, transportation, and nature) and disability on psychosocial well-being (quality of life, thriving, loneliness, and psychological distress). Higher levels of disability and poorer accessibility were each significantly related to lower psychosocial well-being across all variables (p < 0.001). Significant interaction effects were observed between disability and built environment accessibility on thriving (F(8, 5936) = 4.97, p < 0.001, η² = 0.006) and psychological distress (F(8, 5957) = 3.09, p = 0.002, η² = 0.004). No significant interaction effects were found for quality of life and loneliness. These findings indicate good built environment accessibility is associated with thriving and reduces psychological distress among older adults with disabilities. This study supports and extends previous findings on the importance of accessible and equipped environments for well-being and may aid policy makers when planning built environments to foster healthy ageing among this population group.

Circumstances Contributing to Installation, Maintenance, and Repair Worker Death by Suicide

OBJECTIVE

To examine risk factors related to death by suicide among installation, maintenance, and repair (IMR) workers compared with workers in other occupational groups.

METHODS

The National Violent Death Reporting System (NVDRS) data for the years 2013 to 2018 was used to identify suicide deaths. Circumstance variables were used to examine differences between IMR workers and other workers.

RESULTS

Having a physical health problem (1.13; 95% confidence interval [CI], 1.03 to 1.23) or a diagnosis of posttraumatic stress disorder (1.24; 95% CI, 1.03 to 1.50) was more likely to contribute to IMR worker suicide compared with other occupations. Installation, maintenance, and repair workers were less likely to receive treatment for a mental health diagnosis or substance use disorder (0.88; 95% CI, 0.81 to 0.94).

CONCLUSIONS

Additional support for physical health problems, posttraumatic stress disorder diagnoses, and mental health care access among IMR workers may reduce suicide deaths.

Happiness and mental health of older adults: multiple mediation analysis

Introduction

This study aims to explore the influence mechanism of older adult mental health. As the aging population grows, the mental health of older adults becomes a significant public health and social issue, with happiness serving as a key dimension of mental health.

Methods

This study utilizes public data from CGSS to investigate the relationship between happiness and mental health, with Process V4.1 used for mediating effects analysis.

Results

The findings suggest a positive predictive effect of happiness on mental health, with three mediating paths identified: independent mediating effect paths of income satisfaction and health, as well as a multiple mediating effects path through income satisfaction and health.

Discussion

The study suggests that improving the multi-subject mental health support service system for older adults and creating public values for mental health risk coping mechanisms. This helps to understand the complex relationship between aging on individual and social levels. These results provide empirical support for healthy aging among older adults and future policymaking.

Mapping the genetic architecture of suicide attempt and suicide death using polygenic risk scores for clinically-related psychiatric disorders and traits

BACKGROUND

Suicidal behavior is moderately heritable and a consequence of a combination of the diathesis traits for suicidal behavior and suicide-related major psychiatric disorders. Here, we sought to examine shared polygenic effects between various psychiatric disorders/traits and suicidal behavior and to compare the shared polygenic effects of various psychiatric disorders/traits on non-fatal suicide attempt and suicide death.

METHODS

We used our genotyped European ancestry sample of 260 non-fatal suicide attempters, 317 suicide decedents and 874 non-psychiatric controls to test whether polygenic risk scores (PRSs) obtained from large GWASs for 22 suicide-related psychiatric disorders/traits were associated with suicidal behavior. Results were compared between non-fatal suicide attempt and suicide death in a sensitivity analysis.

RESULTS

PRSs for major depressive disorder, bipolar disorder, schizophrenia, ADHD, alcohol dependence, sensitivity to environmental stress and adversity, educational attainment, cognitive performance, and IQ were associated with suicidal behavior (Bonferroni-corrected p < 2.5 × 10^-4). The polygenic effects of all 22 psychiatric disorders/traits had the same direction (p for binomial tests = 4.8 × 10^-7) and were correlated (Spearman's ρ = 0.85) between non-fatal suicide attempters and suicide decedents.

CONCLUSIONS

We found that polygenic effects for major psychiatric disorders and diathesis-related traits including stress responsiveness and intellect/cognitive function contributed to suicidal behavior. While we found comparable polygenic architecture between non-fatal suicide attempters and suicide decedents based on correlations with PRSs of suicide-related psychiatric disorders/traits, our analyses are limited by small sample size resulting in low statistical power to detect difference between non-fatal suicide attempt and suicide death.

Association of Frailty With Risk of Suicide Attempt in a National Cohort of US Veterans Aged 65 Years or Older

Importance

Frailty is associated with reduced physiological reserve, lack of independence, and depression and may be salient for identifying older adults at increased risk of suicide attempt.

Objectives

To examine the association between frailty and risk of suicide attempt and how risk differs based on components of frailty.

Design, Setting, and Participants

This nationwide cohort study integrated databases from the US Department of Veterans Affairs (VA) inpatient and outpatient health care services, Centers for Medicare & Medicaid Services data, and national suicide data. Participants included all US veterans aged 65 years or older who received care at VA medical centers from October 1, 2011, to September 30, 2013. Data were analyzed from April 20, 2021, to May 31, 2022.

Exposures

Frailty, defined based on a validated cumulative-deficit frailty index measured using electronic health data and categorized into 5 levels: nonfrailty, prefrailty, mild frailty, moderate frailty, and severe frailty.

Main Outcomes and Measures

The main outcome was suicide attempts through December 31, 2017, provided by the national Suicide Prevention Applications Network (nonfatal attempts) and Mortality Data Repository (fatal attempts). Frailty level and components of the frailty index (morbidity, function, sensory loss, cognition and mood, and other) were assessed as potential factors associated with suicide attempt.

Results

The study population of 2 858 876 participants included 8955 (0.3%) who attempted suicide over 6 years. Among all participants, the mean (SD) age was 75.4 (8.1) years; 97.7% were men, 2.3% were women, 0.6% were Hispanic, 9.0% were non-Hispanic Black, 87.8% were non-Hispanic White, and 2.6% had other or unknown race and ethnicity. Compared with patients without frailty, risk of suicide attempt was uniformly higher among patients with prefrailty to severe frailty, with adjusted hazard ratios (aHRs) of 1.34 (95% CI, 1.27-1.42; P < .001) for prefrailty, 1.44 (95% CI, 1.35-1.54; P < .001) for mild frailty, 1.48 (95% CI, 1.36-1.60; P < .001) for moderate frailty, and 1.42 (95% CI, 1.29-1.56; P < .001) for severe frailty. Lower levels of frailty were associated with greater risk of lethal suicide attempt (aHR, 1.20 [95% CI, 1.12-1.28] for prefrail veterans). Bipolar disorder (aHR, 2.69; 95% CI, 2.54-2.86), depression (aHR, 1.78; 95% CI, 1.67-1.87), anxiety (aHR, 1.36; 95% CI, 1.28-1.45), chronic pain (aHR, 1.22; 95% CI, 1.15-1.29), use of durable medical equipment (aHR, 1.14; 95% CI, 1.03-1.25), and lung disease (aHR, 1.11; 95% CI, 1.06-1.17) were independently associated with increased risk of suicide attempt.

Conclusions and Relevance

This cohort study found that among US veterans aged 65 years or older, frailty was associated with increased risk of suicide attempts and lower levels of frailty were associated with greater risk of suicide death. Screening and involvement of supportive services across the spectrum of frailty appear to be needed to help reduce risk of suicide attempts.

Physical and mental illness comorbidity among individuals with frequent self-harm episodes: A mixed-methods study

Background

Research has indicated an increased risk of self-harm repetition and suicide among individuals with frequent self-harm episodes. Co-occurring physical and mental illness further increases the risk of self-harm and suicide. However, the association between this co-occurrence and frequent self-harm episodes is not well understood. The objectives of the study were (a) to examine the sociodemographic and clinical profile of individuals with frequent self-harm (regardless of suicidal intent) episodes and, (b) the association between physical and mental illness comorbidity, self-harm repetition, highly lethal self-harm methods, and suicide intent.

Methods

The study included consecutive patients with five or more self-harm presentations to Emergency Departments across three general hospitals in the Republic of Ireland. The study included file reviews (n = 183) and semi-structured interviews (n = 36). Multivariate logistic regression models and independent samples t-tests were used to test the association between the sociodemographic and physical and mental disorders comorbidity on highly lethal self-harm methods and suicidal intent, respectively. Thematic analysis was applied to identify themes related to physical and mental illness comorbidity and frequent self-harm repetition.

Findings

The majority of individuals with frequent self-harm episodes were female (59.6%), single (56.1%), and unemployed (57.4%). The predominant current self-harm method was drug overdose (60%). Almost 90% of the participants had history of a mental or behavioral disorder, and 56.8% had recent physical illness. The most common psychiatric diagnoses were alcohol use disorders (51.1%), borderline personality disorder (44.0%), and major depressive disorder (37.8%). Male gender (OR = 2.89) and alcohol abuse (OR = 2.64) predicted the risk of a highly lethal self-harm method. Suicide intent was significantly higher among those with a diagnosis of major depressive disorder (t = 2.43; p = 0.020). Major qualitative themes were (a) the functional meaning of self-harm (b) self-harm comorbidity (c) family psychiatric history and (d) contacts with mental health services. Participants described experiencing an uncontrollable self-harm urge, and self-harm was referred to as a way to get relief from emotional pain or self-punishment to cope with anger and stressors.

Conclusion

Physical and mental illness comorbidity was high among individuals with frequent self-harm episodes. Male gender and alcohol abuse were associated with highly lethal self-harm methods. The mental and physical illness comorbidity of individuals with frequent self-harm episodes should be addressed via a biopsychosocial assessment and subsequent indicated treatment interventions.

The characteristics, life problems and clinical management of older adults who self-harm: Findings from the multicentre study of self-harm in England

BACKGROUND

Older adults have a high risk of suicide following self-harm. Contemporary information on self-harm in this population is needed to inform care provision.

OBJECTIVES

To examine subgroup differences in the incidence of self-harm, sociodemographic and clinical characteristics, preceding life problems and outcomes in individuals aged 60 years and over presenting to hospital following self-harm.

METHOD

Data on Emergency Department (ED) presentations for self-harm from 2003 to 2016 from three centres in the Multicentre Study of Self-Harm in England were analysed. Changes in self-harm rates were examined using Poisson regression. Univariable logistic regression was used to investigate factors associated with 12-month self-harm repetition.

RESULTS

There were 3850 presentations for self-harm by 2684 individuals aged 60 years and over. Self-harm rates increased over time for 60-74-year-old men (Incident Rate Ratio = 1.04, 95% Confidence Interval 1.02-1.06, p < 0.0001). Problems most frequently reported to have preceded self-harm were mental health (40.5%) and physical health (38.3%) concerns. Problems with alcohol, finances, employment and relationship with partner were found more frequently in 60-74-year-olds compared with those aged over 74 years. Physical health problems were common with increasing age, as were problems with alcohol for men. One in ten (10.8%) individuals presented to hospital with self-harm within 12 months of their index presentation.

CONCLUSIONS

Self-harm-related ED attendances in older men have increased, particularly for men aged 60-74 years. Prevention and clinical management should involve a comprehensive psychosocial assessment to target common precipitants for the wide range of problems preceding self-harm and may include support with physical and mental wellbeing and advice on safer alcohol use.

Suicidal ideation in the general population in China after the COVID-19 pandemic was initially controlled

BACKGROUND

The COVID-19 pandemic increases the risk of psychological problems including suicidal ideation (SI) in the general population. In this study, we investigated the risk factors of SI after the COVID-19 pandemic was initially controlled in China.

METHODS

We conducted an online questionnaire via JD Health APP in China in June 2020. Demographic data, feelings and experiences related to the COVID-19 pandemic and psychological problems were collected. The participants (n = 14,690) were divided into the non-SI and SI groups. A binary logistic regression analysis was used to examine the correlates of SI.

RESULTS

Nine percent of the participants (1328/14690) reported SI. The regression analysis showed that SI was positively associated with ethnic minority (OR = 1.42 [1.08-1.85]), age (e.g. 18-30 years: OR = 2.31 [1.67-3.20]), having history of mental disorders (OR = 2.75 [2.27-3.35]), daily life disturbance due to health problems (OR = 1.67 [1.38-2.01]), being around someone with the COVID-19 (OR = 1.58 [1.30-1.91]), being uncertain about effective disease control (OR = 1.23 [1.03-1.46]), and having depressive symptoms (OR = 4.40 [3.59-5.39]), insomnia symptoms (OR = 2.49 [2.13-2.90]) or psychological distress (OR = 1.87 [1.59-2.18]).

LIMITATIONS

The main limitation is that the cross-sectional design of this study could not allow us to further explore the causality of SI.

CONCLUSIONS

The prevalence of SI was relatively high in general population after the COVID-19 pandemic was initially controlled in China. SI should be monitored continually after the COVID-19 pandemic.

Hospital inpatient suicides: A retrospective comparison between psychiatric and non-psychiatric inpatients in Milan healthcare facilities

INTRODUCTION

Inpatient suicide in hospitals is a worrying phenomenon that has received little attention. This study retrospectively explored the socio-demographic, clinical, and suicide-related characteristics of hospital inpatient suicides in Milan, Italy, which were collected at the Institute of Forensic Medicine during a twenty-eight-year period (1993-2020). In particular, this study compared the features of hospital inpatient suicides in patients with and without psychiatric diagnoses.

METHODS

Data were collected through the historical archive, annual registers, and autopsy reports, in certified copies of the originals deposited with the prosecutors of the courts.

RESULTS

Considering the global sample, inpatients were mainly men (N = 128; 64.6%), with a mean age of 56.7 years (SD ± 19.8), of Italian nationality (N = 176; 88.9%), admitted to non-psychiatric wards (N = 132; 66.7%), with a single illness (N = 111; 56.1%), treated with psychotropic medications (N = 101; 51%), who used violent suicide methods (N = 177; 89.4%), died of organic injuries (N = 156; 78.8%), and outside the buildings (N = 114; 72.7%). Comparing psychiatric and non-psychiatric inpatients, suicide cases with a non-psychiatric diagnosis were predominantly men (N = 48; 76.2%), hospitalized in non-psychiatric wards (N = 62; 98.4%), assuming non-psychotropic drugs (N = 37; 58.7%), and died in outside hospital spaces (N = 54; 85.7%).

CONCLUSIONS

A fuller characterization of suicide among hospitalized inpatients requires systematic and computerized data gathering that provides for specific information. Indeed, this could be valuable for inpatient suicide prevention strategies as well as institutional policies.

Clinical Markers Associated With Risk of Suicide or Drug Overdose Among Individuals With Smoking Exposure: A Longitudinal Follow-up Study of the COPDGene Cohort

BACKGROUND

Studies have shown that COPD and smoking are associated with increased suicide risk. To date, there are no prospective studies examining suicide risk among individuals with smoking exposure along a spectrum of pulmonary diseases ranging from normal spirometry to severe COPD.

RESEARCH QUESTION

Which clinical variables predict death by suicide or overdose of indeterminate intent in a large cohort of individuals with smoking exposure within the Genetic Epidemiology of COPD (COPDGene) study?

STUDY DESIGN AND METHODS

We studied data from 9,930 participants involved in COPDGene, a multisite, prospective cohort study of individuals with smoking exposure. Primary cause of adjudicated deaths was identified by using death certificates, family reports, and medical records. Time to death by suicide/overdose was examined as the primary outcome in Cox regression models including age, sex, race, BMI, pack-years, current smoking status, airflow limitation (FEV1 % predicted), dyspnea (modified Medical Research Council scale score ≥ 2), 6-min walk distance, supplemental oxygen use, and severe exacerbations in the prior year with time-varying covariates and other causes of death as a competing risk.

RESULTS

The cohort was 47% female and 33% Black (67% White); they had a mean ± SD age of 59.6 ± 9.0 years and a mean FEV1 % predicted of 76.1 ± 25.5. Sixty-three individuals died by suicide/overdose. Factors associated with risk of suicide/overdose were current smoking (hazard ratio [HR], 6.44; 95% CI, 2.64-15.67), use of sedative/hypnotics (HR, 2.33; 95% CI, 1.24-4.38), and dyspnea (HR, 2.23; 95% CI, 1.34-3.70). Lower risk was associated with older age (per-decade HR, 0.45; 95% CI, 0.31-0.67), higher BMI (HR, 0.95; 95% CI, 0.91-0.99), and African-American race (HR, 0.41; 95% CI, 0.23-0.74). Severity of airflow limitation (FEV % predicted) was not associated with suicide risk.

INTERPRETATION

In this well-characterized cohort of individuals with smoking exposure with and without COPD, risk factors for suicide/overdose were identified that emphasize the subjective experience of illness over objective assessments of lung function.

Characteristics of suicide decedents with no federally funded mental health service contact in the 12 months before death in a population-based sample of Australians 45 years of age and over

INTRODUCTION

More than half of suicide decedents have no contact with mental health services 12 months before death. It is uncertain if they have different characteristics than decedents who use mental health services.

METHODS

A case-series design. Participants 45 years and older, who died by suicide (2006-2018). Comparisons were made between those who did and did not have contact with mental health services, using individually linked data from federal services in the Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS).

RESULTS

Of 186 cases, 71% had no contact with mental health services. Physical health services were used equally by 75%. Psychiatric medication use was uncommon, except for antidepressants, 50% with mental health service contact and 20% with no contact. Older age, lower income, involuntarily unemployed, firearms as suicide method, greater physical disability, less functional impairment due to emotional problems and lesser proportions with mental illness, were associated with no contact with mental health services.

CONCLUSIONS

For suicide prevention, middle-older aged adults may have less requirement for mental health intervention, and greater requirement for the development of complementary interventions focused on physical health and social issues, which are not necessarily best delivered by clinical mental health services.

Physical disability, low self-esteem, and suicidal ideation among Chinese nursing home residents: the moderating role of resilience

OBJECTIVES

This study aimed to investigate the mediating role of self-esteem in the relationship between physical disability and suicidal ideation, and whether the mediation effect was moderated by resilience among nursing home residents.

METHODS

Participants were 538 nursing home residents recruited from 37 nursing homes in Jinan, China (mean age = 78.13 years, SD = 8.72). The Lawton and Brody Activities of Daily Living Scale, Rosenberg Self-Esteem Scale, 10-item version of the Connor-Davidson Resilience Scale, and Beck Suicidal Ideation Inventory-Chinese Version were used. Mediation and moderated mediation analyses were performed using Models 4 and 15 of the PROCESS macro for SPSS.

RESULTS

The prevalence of suicidal ideation among the nursing home residents was 14.90%. The mediation analysis showed that self-esteem partially mediated the association between physical disability and suicidal ideation. Resilience was a protective factor for suicidal ideation and moderated the relationship between physical disability and suicidal ideation, and between self-esteem and suicidal ideation.

CONCLUSION

Both physical disability and lower self-esteem are important in understanding the development of suicidal ideation among nursing home residents. Improving resilience may be crucial for suicide prevention.

Understanding for Prevention: Qualitative and Quantitative Analyses of Suicide Notes and Forensic Reports

Suicide risk is associated with vulnerabilities and specific life events. The study's objective was to explore the relevance of data from forensic documentation on suicide deaths to the design of person-centered preventive strategies. Descriptive and thematic analyses were conducted of forensic observations of 286 deaths by suicide, including some with suicide notes. Key findings included the influence of health-and family-related adverse events, emotional states of loss and sadness, and failures of the health system to detect and act on signs of vulnerability, as confirmed by the suicide notes. Forensic documentation provides useful information to improve the targeting of preventive campaigns.

Suicide Risk Help-Seeking Among Middle- to Old-Age Adults: A Systematic Review

Background and Objectives

Suicide has become a major public health concern worldwide and in the United States. Rates of suicide increase during the life course and are highest among middle- to old-age adults. Help-seeking represents a crucial coping mechanism that can mitigate suicide risk. Yet, less is known about suicide risk help-seeking, especially among these age groups. To address this knowledge gap, a systematic review of existing literature was performed to obtain a refined understanding of help-seeking for suicide risk among middle- to old-age adults.

Research Design and Methods

Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, electronic databases and key journals with suicide and/or gerontology focuses were searched to identify peer-reviewed publications in English between 2010 and 2020. A total of 4 732 unduplicated publications were screened for relevance based on titles and abstracts, of which 52 were reviewed in full text.

Results

Twenty-four articles met inclusion criteria and were included in the qualitative synthesis. These articles discussed a range of topics, including the prevalence of service utilization, service use prior to a suicide death, and correlates of help-seeking. In general, the prevalence of service utilization was low and varied by suicidal history (eg, higher prevalence among individuals with a history of suicide attempts than those with suicide ideation only). Key facilitators (eg, current or history of suicidal thoughts, plans, or attempts) and barriers (eg, stigma) for service use and help-seeking were also identified.

Discussion and Implications

Findings highlight the need for future studies and tailored services to improve age-appropriate and culturally responsive suicide prevention and intervention strategies for middle- to old-age adults.

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.
