New Research on Older Adult Suicide: A Reason for Hope

A scoping review exploring the ‘grey area’ of suicide-related expression in later life: Developing a conceptual framework for professional engagement

As the body of research on suicide in later life has developed, so has its vocabulary. This has generated a high level of overlap in concepts and terminology used to articulate suicide and how it might present, as well as ‘grey area’ behavioural terms that are both specific to older adults and less well-defined (e.g. ‘hastening of death’ or ‘completed life’). A better understanding of individual experiences and pathways to suicide can help to inform assessment and interventions, and increase the potential to relate any theoretical concepts to the implementation of such. Here, we adopted a scoping review to search systematically literature on specific presentation, features, circumstances and outcomes of these grey areas of suicide in later life. Fifty-three articles (quantitative, qualitative and theoretical) were reviewed. A narrative approach was used to merge and translate this body of knowledge into a new conceptual framework based on four key themes: (a) a sense of completed life or existential loneliness; (b) death thoughts, wishes and ideation; (c) death-hastening behaviour and advanced directives; and (d) self-destructive or self-injurious behaviour. We discuss the importance of integrating this understanding into current knowledge and suicide prevention strategies for older adults. Recommendations are made for unifying research with policy themes on healthy ageing, person-centredness within service provision and citizen participation.

Empirically Evaluated Suicide Prevention Program Approaches for Older Adults: A Review of the Literature from 2009-2021

Mental health in later life and suicide risk among older adults are important topics for social work. There is evidence-based research to support the use selective and indicated strategies for suicide prevention, yet, universal prevention approaches are also needed. However, the extent to which the broader contexts of suicide have been examined remains largely absent from the literature. This article presents findings from a systematic review of articles published between 2009 and 2021, focusing what types of empirically evaluated suicide prevention programs effectively prevent and reduce suicidality in older adults. Using the PICO and PRISMA guidelines, a final sample of 8 articles were reviewed in this systematic review. The articles were categorized into three types of programs: 1) primary and home health care, 2) community-based outreach, and 3) counseling. The articles also examined the involvement of social workers in these programs. Following a description of the articles, the authors assess each study using the GRADE rating system. Lastly, the authors discuss the role of the social worker in mental health promotion and prevention strategies.

Suicide Distribution and Trends Among Male Older Adults in the U.S., 1999-2018

INTRODUCTION

This study examines the distribution and trends in suicide death rates among male adults aged ≥65 years in the U.S. from 1999 to 2018.

METHODS

Suicide mortality data were derived from Multiple Cause of Death from the Center for Disease Control and Prevention's Wide-ranging Online Data for Epidemiologic Research database. Suicides were identified from the underlying causes of death. Joinpoint regression examined the distribution and shift in suicide age-adjusted death rates overall and by age groups, race/ethnicity, method of suicide, and urbanicity. Analyses were conducted in 2020.

RESULTS

Between 1999 and 2018, a total of 106,861 male adults aged ≥65 years died of suicide (age-adjusted rate=31.4 per 100,000 population, 95% CI=31.2, 31.6). Suicide rates showed a V-shaped trend. They were declining annually by 1.8% (95% CI= -2.4, -1.2); however, starting in 2007, there was a shift upward, increasing significantly by 1.7% per year for the next decade (95% CI=1.0, 1.6). Suicide rates were highest among those aged ≥85 years (48.8 per 100,000 population with an upward shift in 2008), Whites (35.3 per 100,000 population with an upward shift in trend in 2007), and the most rural communities (39.0 per 100,000 population). Most suicides were due to firearms (78.3% at a rate of 24.7 per 100,000 population), especially in rural areas, and shifted upward after 2007.

CONCLUSIONS

Increases in suicide rates among male older adults in the U.S., particularly after the 2007-2008 economic recession, are concerning. Tailored suicide prevention intervention strategies are needed to address suicide-related risk factors.
