A Systematic Review of Factors Impacting Suicide Risk Among Rural Adults in the United States

Examining the impact of the veterans affairs community care program on mental healthcare in rural veterans: A qualitative study

OBJECTIVE

To investigate provider and administrators' perspectives about the impact of the Department of Veterans Affairs' (VA) Community Care program on acute and residential mental health treatment of rural Veterans.

DATA SOURCES AND STUDY SETTING

Primary data were collected from participants via interviews. Participants were employees of VA Healthcare Systems located in Northern New England, or employees of non-VA mental health treatment settings affiliated with VA in Northern New England.

STUDY DESIGN

This study was informed by the Consolidated Framework for Implementation Research (CFIR), with Community Care as the implemented program. Individual, semi-structured interviews were conducted.

DATA COLLECTION/EXTRACTION METHODS

Individual interviews were transcribed, coded deductively using the CFIR, and inductively coded by locating themes.

PRINCIPAL FINDINGS

Twenty-one people completed interviews. Commonly reported challenges included community programs not focused on Veterans' needs, poor coordination of care, communication challenges, and problems tracking Veteran care. Facilitators included increased access to care and strengthening coordination of care.

CONCLUSIONS

The VA's Community Care program can address the acute or residential mental health needs of Veterans in rural settings in some circumstances, however there are challenges to successful implementation.

County Characteristics and Veteran Suicide in the United States, 2011-2018

INTRODUCTION

Few studies have examined county-level hotspots of veteran suicide and associated place-based contributors, limiting development of targeted community-level prevention strategies. The objectives of this national spatial analysis of all veteran suicides were to identify areas of the United States with higher-than-expected veteran suicide rates and determine county-level social and economic characteristics associated with areas of higher risk.

METHODS

Using Bayesian hierarchical modeling, county-level standardized mortality ratios for veteran suicide deaths were estimated for time periods 2011-2018, 2011-2014, and 2015-2018. Adjusted relative risk, accounting for community characteristics, for each county was then estimated and associations between community characteristics and veteran suicide risk were examined. Analyses were conducted in 2023-2024.

RESULTS

Risk of veteran suicide is predominantly concentrated in the Mountain West and West. Significant predictors of risk across all time periods were per capita number of firearm retailers (2011-2018 relative risk [RR]=1.065 [95% credible interval [CI] 1.030-1.102]), the proportion of residents who moved in the past year (2011-2018 RR=1.060 [95% CI 1.039-1.081]), the proportion of residents who live alone (2011-2018 RR=1.067 [95% CI 1.046-1.089]), the proportion of residents in rental housing (2011-2018 RR=1.041 [95% CI 1.018-1.065]), and the proportion of married residents (2011-2018 RR=0.915 [95% CI 0.890-0.941]).

CONCLUSIONS

This study contributes to a comprehensive public health approach to veteran suicide prevention by identifying where resources are needed most, and which place-based intervention targets have the largest potential for impact. Findings suggest that public health efforts to address suicide among veterans should address community-level firearm access and identify ways to alleviate deleterious effects of social fragmentation.

Spatially clustered patterns of suicide mortality rates in South Korea: a geographically weighted regression analysis

BACKGROUND

Suicide mortality remains a global health concern, and community characteristics affect regional variations in suicide. This study investigated spatially clustered patterns of suicide mortality rates in South Korea and evaluated the impact of community factors on suicide.

METHODS

Suicide mortality rates were estimated by sex, age group, and district, using the 2021 Cause of Death Statistics in South Korea from the MicroData Integrated Service. Community-determinant data for 2021 or the nearest year were collected from the Korean Statistical Information Service. The spatial autocorrelation of suicide by sex and age was examined based on Global Moran's I index. Geographically weighted regression (GWR) was used to discern the influence of community determinants on suicide.

RESULTS

Suicide mortality rates were significantly higher among men (40.64 per 100,000) and adults over the age of 65 years (43.18 per 100,000). The male suicide mortality rates exhibited strong spatial dependence, as indicated by a high global Moran's I with p < 0.001, highlighting the importance of conducting spatial analysis. In the GWR model calibration, a subset of the community's age structure, single-person household composition, access to mental healthcare centers, and unmet medical needs were selected to explain male suicide mortality. These determinants disproportionately increased the risk of male suicide, varying by region. The GWR coefficients of each variable vary widely across 249 districts: aging index (Q1:0.06-Q3:0.46), single-person households (Q1:0.22-Q3:0.35), psychiatric clinics (Q1:-0.20-Q3:-0.01), and unmet medical needs (Q1:0.09-Q3:0.14).

CONCLUSIONS

Community cultural and structural factors exacerbate regional disparities in suicide among men. The influencing factors exhibit differential effects and significance depending on the community, highlighting the need for efficient resource allocation for suicide. A regionally tailored approach is crucial for the effective control of the community's mental health management system.

An introduction to bayesian spatial smoothing methods for disease mapping: modeling county firearm suicide mortality rates

This article introduces bayesian spatial smoothing models for disease mapping-a specific application of small area estimation where the full universe of data is known-to a wider audience of public health professionals using firearm suicide as a motivating example. Besag, York, and Mollié (BYM) Poisson spatial and space-time smoothing models were fitted to firearm suicide counts for the years 2014-2018. County raw death rates in 2018 ranged from 0 to 24.81 deaths per 10 000 people. However, the highest mortality rate was highly unstable, based on only 2 deaths in a population of approximately 800, and 80.5% of contiguous US counties experienced fewer than 10 firearm suicide deaths and were thus suppressed. Spatially smoothed county firearm suicide mortality estimates ranged from 0.06 to 4.05 deaths per 10 000 people and could be reported for all counties. The space-time smoothing model produced similar estimates with narrower credible intervals as it allowed counties to gain precision from adjacent neighbors and their own counts in adjacent years. bayesian spatial smoothing methods are a useful tool for evaluating spatial health disparities in small geographies where small numbers can result in highly variable rate estimates, and new estimation techniques in R software have made fitting these models more accessible to researchers.

A PRISMA Scoping Review to Explore Interventions to Prevent Firearm-Related Injury and Suicide in Older Adults

OBJECTIVES

This scoping review aims to examine existing research into firearm safety interventions designed to prevent firearm injury and suicide in older adults.

METHODS

Select databases were searched in 5/2023. Included articles involved an/a 1. aim to develop or investigate firearm safety interventions, 2. focus on adults 50 years and older, and 3. primary analysis.

RESULTS

The search yielded 10 articles which primarily focused on firearm safety counseling with older adults with suicide risk or emerging impairment. The review found that older adults may be open to receiving firearm safety counseling but that providers feel ill-equipped to have these conversations and to reliably identify suicide risk. Two studies presented promising data on the impact and acceptability of training providers in a firearm safety intervention. The review also identified the importance of building trust between older patients and providers to have helpful discussions regarding firearms, and highlighted specific approaches that facilitate openness to participate in these exchanges.

CONCLUSIONS

Further research into adapting interventions to meet the clinical needs of older adults and treatment efficacy trials is necessary.

CLINICAL IMPLICATIONS

Training healthcare providers to conduct firearm safety interventions with older adults may be an acceptable and impactful avenue to prevent suicide.

Costs of Fatal and Nonfatal Firearm Injuries in the U.S., 2019 and 2020

INTRODUCTION

Firearm-related injuries are among the five leading causes of death for people aged 1-44 years in the U.S. The immediate and long-term harms of firearm injuries pose an economic burden on society. Fatal and nonfatal firearm injury costs in the U.S. were estimated providing up-to-date economic burden estimates.

METHODS

Counts of nonfatal firearm injuries were obtained from the 2019-2020 Healthcare Cost and Utilization Project Nationwide Emergency Department Sample. Data on nonfatal injury intent were obtained from the National Electronic Injury Surveillance System - Firearm Injury Surveillance System. Counts of deaths (firearm as underlying cause) were obtained from the 2019-2020 multiple cause-of-death mortality data from the National Vital Statistics System. Analyses were conducted in 2023.

RESULTS

The total cost of firearm related injuries and deaths in the U.S. for 2020 was $493.2 billion, a 16 percent increase compared with 2019. There are significant disparities in the cost of firearm deaths in 2019-2020, with non-Hispanic Black people, males, and young and middle-aged groups being the most affected.

CONCLUSIONS

Most of the nonfatal firearm injury-related costs are attributed to hospitalization. These findings highlight the racial/ethnic differences in fatal firearm injuries and the disproportionate cost burden to urban areas. Addressing this important public health problem can help ameliorate the costs to our society from the rising rates of firearm injuries.

Pre-implementation adaptation of suicide safety planning intervention using peer support in rural areas

Introduction

Currently, seventeen veterans die by suicide daily in the United States (U.S.). There are disparities in suicide behavior and access to preventative treatment. One disparity is the suicide rate in rural areas, including the state of Arkansas-suicide deaths among rural veterans increased 48% in the last 2 decades, double that of urban veterans. One major challenge for veterans in rural areas is the lack of healthcare providers to provide Safety Planning Intervention, which is an effective intervention to reduce suicide attempts in the general adult population and among veterans. One solution is more broadly implementing Safety Planning Intervention, by using peers to deliver the intervention in rural communities. Before implementation, the intervention needs to be adapted for peer-to-peer delivery, and barriers and facilitators identified.

Methods

Since January 2021, using community-based participatory research, we collaboratively developed and executed a 1 year study to adapt Safety Planning Intervention for peer-to-peer delivery in rural communities and identified implementation barriers and facilitators prior to spread. From July 2022 to February 2023, we conducted group interviews with 12 participants: rural veterans with prior suicidal thoughts or attempts in one U.S. state, their support persons, and healthcare professionals with expertise in veteran suicide prevention, Safety Planning Intervention, and/or peer delivery. We collected qualitative data through interviews during nine, 2 h meetings, and quantitative data from one anonymous survey and real-time anonymous voting-all on the topic of core and adaptable components of Safety Planning Intervention and implementation barriers and facilitators for peer delivery in rural communities. Questions about adaptation were designed according to processes in the ENGAGED for CHANGE community-engaged intervention framework and questions about facilitators and barriers were designed according to the Health Equity Implementation Framework. Participants categorized which Safety Planning Intervention components were core or adaptable, and how freely they could be adapted, using the metaphor of a traffic light in red (do not change), yellow (change with caution), and green (change freely) categories.

Results

Participants made few actual adaptations (categorized according to the FRAME modification system), but strongly recommended robust training for peers. Participants identified 27 implementation facilitators and 47 barriers, organized using the Health Equity Implementation Framework. Two example facilitators were (1) peer-to-peer safety planning intervention was highly acceptable to rural veterans; and (2) some state counties already had veteran crisis programs that could embed this intervention for spread. Two example barriers were (1) some community organizations that might spread the intervention have been motivated initially, wanting to help right away, yet not able to sustain interventions; and (2) uncertainty about how to reach veterans at moderate suicide risk, as many crisis programs identified them when suicide risk was higher.

Discussion

Our results provide one of the more comprehensive pre-implementation assessments to date for Safety Planning Intervention in any setting, especially for peer delivery (also referred to as task shifting) outside healthcare or clinical settings. One important next step will be mapping these barriers and facilitators to implementation strategies for peer-to-peer delivery. One finding surprised our research team-despite worse societal context in rural communities leading to disproportionate suicide deaths-participants identified several positive facilitators specifically about rural communities that can be leveraged during implementation.

Self-reported suicidal behaviours and associated factors in the general population of Latvia (2010-2018)

BACKGROUND

Latvia has the second highest suicide rate in the European Union - with a total population age-standardized suicide rate of 16.1 per 100,000 inhabitants.

AIMS

We aimed to assess the prevalence of different types of self-reported suicidal behaviours in Latvia and determine the associated sociodemographic and health-related factors.

METHODS

This study was based on secondary data obtained from the Health Behaviour Among Latvian Adult Population survey. A representative sample of the general population was used, aged 15 to 64 years in 2010, 2012, 2014; and 15 to 74 years in 2016 and 2018 (n = 16,084). Respondents were asked to report the occurrence of life weariness, death wishes, suicidal ideation, suicidal plans and suicide attempts during the previous year. We assessed socio-demographics and health-related factors associated with suicidality. We performed univariate analysis and constructed stepwise multivariate logistic regression models.

RESULTS

In 2010 to 2018, 15.6% of responders reported some type of suicidal behaviour (95% CI [15.1, 16.2]). Sociodemographic factors - including non-cohabitation status and Latvian nationality - were associated with mild (life-weariness and death wishes) and serious (suicidal ideation, plans to commit suicide, suicide attempts) types of behaviour. Older age was associated with mild suicidal behaviours, whereas lower educational levels were associated with serious suicidal behaviours. Diagnosed depression, self-reported depression, self-reported anxiety, stress, low mood, alcohol intake habits with heavy drinking episodes (less than monthly, monthly and weekly), perceived health as average or below average, disuse of primary health services were associated with mild and serious types of suicidal behaviour. Current smoking status and absenteeism were associated with mild suicidal behaviour types. Self-reported insomnia, having at least two somatic diagnoses, occasional smoking status, absenteeism with 11 or more days in the last year, receiving disability pension were associated with serious suicidal behaviour types. Musculoskeletal diseases exhibited preventive effects.

CONCLUSIONS

Our findings indicate that certain groups of individuals might exhibit greater vulnerability to suicidality.

Let's Talk About Firearms: Perspectives of Older Veterans and VA Clinicians on Universal and Dementia-Specific Firearm Safety Discussions

OBJECTIVES

Veterans experience high rates of fatal and non-fatal firearm injuries. This risk may be compounded among Veterans who are rural-residing, aging, and/or experiencing cognitive decline or dementia. Firearm safety discussions are not broadly implemented across Department of Veterans Affairs (VA) healthcare settings due, in part, to concerns of causing Veterans to disengage from care. This study examines perceptions about firearm safety discussions to inform healthcare-based harm-reduction efforts.

METHODS

We conducted interviews with 34 Veterans (median age 70) and 22 clinicians from four VA facilities that treat high rates of rural patients with firearm-related injuries.

RESULTS

Most Veterans accepted the idea of universal firearm safety discussions at the VA. Some reported they might not be forthright in such discussions, but raising the topic would not stop them from engaging with VA care. Veterans and clinicians unanimously endorsed firearm safety discussions for older patients experiencing cognitive decline or dementia.

CONCLUSIONS

VA patients and clinicians are amenable to firearm safety discussions during healthcare visits and especially endorse the need for such discussions among high-risk populations.

CLINICAL IMPLICATIONS

Universal firearm safety discussions could be incorporated into standard VA practice, particularly for Veterans experiencing cognitive decline or dementia, without risking Veteran disengagement from care.

The charm of country life? Impact of rural childhood residence on physical and mental health in later life

BACKGROUND

Most studies of geographic health disparities are focused on adult rural residence. However, previous studies have shown that the residential area in which one grows up during childhood has lasting impacts on adult health. In one of the only studies to date to examine the impact of rural childhood residence on mental health in middle-aged and older adults, Murchland and colleagues (2019) evaluated inequalities by childhood residence and noted elevated depressive symptoms were more common among those living in rural areas compared to those living in non-rural areas.

AIMS

The current study expands the model proposed by Murchland and colleagues to include further antecedents related to rural childhood residence, and to include multiple outcomes of physical and mental health among middle-aged and older adults.

METHOD

Participants included 4614 individuals aged 40 or older recruited as part of the Midlife in the United States (MIDUS) study.

RESULTS

Consistent with Murchland's model, childhood rurality played an important part in middle-aged and older adult's health, despite not having a direct influence. Rurality status was impacted by parental education level and SES during childhood, and was associated with the level of education obtained by the participants (and thus their occupation), which played a direct role in their current health status. Mental and physical health had differential predictors.

LIMITATIONS

The study was limited by its non-diverse sample and self-reported measures.

CONCLUSION

Further research into the impact of childhood rurality on health is needed, utilizing comprehensive self-reported and observed outcome measures.

Veteran suicide and associated community characteristics in Oregon

Developing a public health approach to suicide prevention among United States (US) military veterans requires additional data and guidance on where, when, for whom, and what prevention resources should be deployed. This study examines veteran suicide mortality across one US state (Oregon) to identify county-level "hotspots" for veteran suicide, identify community characteristics associated with increased suicide among veterans, and examine excess spatial risk after accounting for space, time, and community characteristics. We linked Oregon mortality data with VA databases to identify veterans who had resided in Oregon and died by suicide between January 1, 2009 and December 31, 2018 (n = 1727). Community characteristic data were gathered at the county level from publicly available datasets on social determinants of health known to be associated with poor health outcomes, including suicide risk. We estimated spatial generalized linear mixed models for the full 10-year period and for each 5-year period using integrated nested Laplace approximation with county as the higher hierarchy. Smoothed standardized mortality ratios were used to identify counties with higher risk of veteran suicide. We found a small clustering of counties in the southwestern corner of Oregon that held the highest risk for veteran suicide across the ten years studied. In multivariable models, higher prevalence of unmarried persons was the only community measure significantly associated with increased veteran suicide risk. However, social contextual factors as a group, along with geographic space, explained most risk for suicide among veterans at the population level.

Challenges, Successes, and the Future of Firearm Injury Prevention

Policy Points Firearm injury is a leading cause of death in the United States, with fatality rates increasing 34.9% over the past decade (2010-2020). Firearm injury is preventable through multifaceted evidence-based approaches. Reviewing past challenges and successes in the field of firearm injury prevention can highlight the future directions needed in the field. Adequate funding, rigorous and comprehensive data availability and access, larger pools of diverse and scientifically trained researchers and practitioners, robust evidence-based programming and policy implementation, and a reduction in stigma, polarization, and politicization of the science are all needed to move the field forward.

Identification of Risk Factors for Suicide and Insights for Developing Suicide Prevention Technologies: A Systematic Review and Meta-Analysis

Suicide is a termite that engulfs close to seven hundred thousand people worldwide each year. Existing work on risk factors that predict suicide lacks statistical associations, does not consider most countries, and has a wide range of risk factor domains. The goal of this systematic review and meta-analysis is to enhance our current understanding of suicidality by identifying risk factors that are most strongly associated with suicide and their impact on developing technological interventions for suicide prevention. A search strategy was carried out on four databases: (1) PsycINFO, (2) IEEE Xplore, (3) the ACM Digital Library, and (4) PubMed, and twenty-five studies were included based on the inclusion criteria. Factors statistically associated with suicide are any diagnosed mental disorder, adverse life events, past suicide attempts, low education level, loneliness or high levels of isolation, bipolar disorder, depression, multiple chronic health conditions, family history of suicide, sexual trauma, and being female. Domain-wise, comorbid disorders, and behavior-related risk factors are most strongly associated with suicide. We present a new hierarchical model of risk factors for suicide that advances our understanding of suicide and its causes. Finally, we present open research directions and considerations for developing suicide prevention technologies.

School-based obesity prevention programs in rural communities: a scoping review

OBJECTIVE

The objective of this review was to examine existing literature and conceptually map the evidence for school-based obesity prevention programs implemented in rural communities, as well as identify current gaps in the literature.

INTRODUCTION

Pediatric obesity is a significant public health condition worldwide. Rural residency places children at increased risk of obesity. Schools have been identified as an avenue for obesity prevention in rural communities.

INCLUSION CRITERIA

We considered citations focused on children (5 to 18 years of age) enrolled in a rural educational setting. We included obesity prevention programs delivered in rural schools that focused on nutrition or dietary changes, physical activity or exercise, decreasing screen time, or combined nutrition and physical activity that aimed to prevent childhood obesity. We included all quantitative, qualitative, and mixed methods research designs, as well as text and opinion data.

METHODS

A search was conducted of published and unpublished studies in English from 1990 through April 2020 using PubMed, CINAHL Complete, ERIC, Embase, Scopus, Academic Search Premier, Cochrane Register of Controlled Trials, and ClinicalTrials.gov. Gray literature was also searched. After title and abstract review, potentially relevant citations were retrieved in full text. The full texts were assessed in detail against the inclusion criteria by 2 independent reviewers. Included citations were reviewed and data extracted by 2 independent reviewers and captured on a spreadsheet targeting the review objectives.

RESULTS

Of the 105 studies selected for full-text review, 72 (68.6%) were included in the final study. Most of the studies (n = 50) were published between 2010 and 2019 and were conducted in the United States (n = 57). Most studies included children in rural elementary or middle schools (n = 57) and targeted obesity prevention (n = 67). Teachers implemented the programs in half of the studies (n = 36). Most studies included a combination of physical activity and nutrition components (n = 43). Other studies focused solely on nutrition (n = 9) or physical activity (n = 9), targeted obesity prevention policies (n = 9), or other components (n = 8). Programs ranged in length from weeks to years. Overall, weight-related, physical activity-specific, and nutrition-specific outcomes were most commonly examined in the included citations.

CONCLUSIONS

Obesity prevention programs that focused on a combination of physical activity and nutrition were the most common. Multiple outcomes were examined, but most programs included weight-specific and health behavior-specific outcomes. The length and intensity of rural school-based obesity prevention programs varied. More research examining scientific rigor and specific outcomes of rural school-based obesity prevention programs is needed.

Associations between Suicidal Ideation and Relatives' Physical and Mental Health among Community Residents: Differences between Family Members and Lineal Consanguinity

(1) Background: Despite the verified relationship between relatives’ characteristics and individual suicidal ideation, few studies have discussed the role of family members and lineal consanguinity independently according to whether they live together with the individuals or not. (2) Methods: The data in this study were collected in November 2019 and identified rural adults over 18 years old in Shandong as the survey objects, with a total of 879 valid cases included in this survey. Logistic regression analysis was employed to examine the risk factors affecting adults’ suicidal ideation and differentiate the effects of a family member and lineal consanguinity’s physical and mental health. Relatives’ physical and mental health were estimated by three aspects: whether they were suffering from chronic diseases, mental illness, or alcoholism. (3) Results: The study showed that a family member’s physical (OR = 2.303, p < 0.01) and mental health (OR = 5.877, p < 0.05) was related to suicidal ideation, but the association between lineal consanguinities’ physical and mental health and suicidal ideation were not supported. People over 40 years old (OR = 6.528, p < 0.05), from only-child families (OR = 4.335, p < 0.01), with household indebtedness (OR = 2.992, p < 0.001), or difficulty falling asleep (OR = 3.165, p < 0.001) had risk factors of suicidal ideation. (4) Conclusions: The physical and mental health of individuals’ family members are related to their suicidal ideation, and their lineal consanguinities’ physical and mental health are not related to suicidal ideation. These findings imply the different associations between family environment, genetic factors, and suicidal ideation. Family members’ health should be considered as a factor to prevent and control suicidal behaviors, including suicidal ideation.

Rural-Urban Comparisons in the Rates of Self-Harm, U.S., 2018

INTRODUCTION

This study compares rural and urban differences in the rates of nonfatal self-harm in the U.S. in 2018.

METHODS

Nationwide Emergency Department Sample and Census data were analyzed to calculate the RR of emergency department visits for self-harm between rural and urban residents. The analyses were conducted in 2021.

RESULTS

Among a weighted total of 488,000 emergency department visits for self-harm in the U.S., 80.5% were urban residents, and 18.3% were rural residents. In both settings, poisoning was the most common mechanism for self-harm, followed by cutting. Firearm-related self-harm and suffocation each accounted for <2% of total self-harm cases. Overall, the age-adjusted emergency department visit rate for self-harm was 252.3 per 100,000 for rural residents, which was 1.5 (95% CI=1.4, 1.6) times greater than the rate for urban residents (170.8 per 100,000 residents). The rates of self-harm among rural residents were higher than those of urban residents for both male and female residents, for all age groups except people aged ≥65 years, and by all mechanisms.

CONCLUSIONS

Comprehensive suicide prevention strategies tailored to rural communities may mitigate the rural-urban disparity in morbidity from suicidal behavior.

Increased rates of suicide ideation and attempts in rural dwellers following the SARS-CoV-2 pandemic

PURPOSE

Those factors identified to increase the risk of suicide in rural dwellers were exacerbated by the SARS-CoV-2 pandemic, specifically economic factors, substance use, access to health care, and access to lethal weapons. Because the effects of SARS-CoV-2 on suicide ideation and attempts in rural populations have not been fully characterized in published literature, this study compares: (1) the rates of suicide ideation and attempts between the 6 months affected by SARS-CoV-2 to same months of the preceding year (3/18/2020-9/18/20; 3/18/2019-9/18/19), (2) demographics (ie, age, sex, residence, race, and ethnicity), and (3) the locations in which the encounters were billed (inpatient, outpatient, and emergency department).

METHODS

Deidentified claims data associated with patient encounters billed for Suicide Ideation and Suicide Attempt were grouped based on time period and analyzed using descriptive statistics, incidence rate ratio (IRR), 2-sample t-test, chi-square test of association, or Fisher's exact test.

FINDINGS

Suicidal ideation encounters increased in the 6 months post-SARS-CoV-2 when compared to the 6 months of the prior year (IRR = 1.19; P < .001). Males (IRR = 1.27, P < .001), those residing rural areas (IRR = 1.22, P = .01), and Black, non-Hispanic (IRR = 1.24, P = .024) were found to have increased rates of suicide ideation post-SARS-Cov-2. In adults, White, non-Hispanics (IRR = 1.16; P < .001) had increased rates of post-SARS-CoV-2. In the pediatric subset, those who were aged 14-17 (IRR = 1.50; P < .001), resided in rural areas (IRR = 1.61, P = .009), and idenitifed as Hispanic (IRR = 1.89; P = .037) or Black, non-Hispanic (IRR = 1.61, P = .009) had increased rates post-SARS-CoV-2.

CONCLUSIONS

Our study identified rural dwellers to be at increased risk for suicide ideation.

The role of race in rural-urban suicide disparities

PURPOSE

To assess the role that race-ethnicity plays in modifying the observed rural-urban disparity in suicide among Veteran Health Administration (VHA) users.

METHODS

We performed a retrospective cohort study of 10,737,864 VHA users between 2003 and 2017, using cross-linked VHA medical records and National Death Index mortality data to assess longitudinal race-stratified rural-urban differences in age- and sex-adjusted annual suicide rates. We used Poisson regression and generated incident rate ratios (IRRs) to formally assess the impact of race on the rural-urban suicide disparity. Given evidence of effect modification, we performed additional race-stratified Poisson regression models.

FINDINGS

Rurality is significantly associated with a higher risk of suicide in models which do not control for race (IRR = 1.14, 95% CI: 1.10-1.17). However, when race is added to the model, rural residence is no longer significant (0.98, CI: 0.95-1.01). Stratified models demonstrate that rural residence is significantly associated with a higher suicide risk among Hispanic VHA users (1.41, CI: 1.11-1.79), but it is not substantially associated with suicide among White (0.97, CI: 0.94-1.00) and Black (1.03, CI: 0.86-1.23) VHA users. White VHA users have considerably higher suicide rates than Black and Hispanic VHA users, though the suicide rate among Hispanic VHA users, particularly those in rural settings, increased markedly over the period of observation.

CONCLUSIONS

Race significantly modifies the relationship between rural residence and suicide risk. Studies seeking to assess suicide disparity between rural and urban VHA user populations must include adjustment or stratification by race.
