Application of tests for contagion in point processes to measles, Chlamydia, Lyme disease, and suicide

A recently proposed likelihood-ratio test for identifying causal triggering in point process data is applied to a variety of case counts of diseases of varying infectiousness. The test, suggested by McGovern et al. (2023), involves comparing the likelihood of a fitted Hawkes model to that of a fitted Poisson cluster model, and was shown using simulations to be powerful at discriminating between a process with causal triggering and a process where the clustering is merely due to spatial-temporal inhomogeneity. Here, the test is applied to data on measles, Chlamydia, and Lyme disease in the United States, to see if the test can discern between diseases that are highly contagious, moderately contagious, and not directly contagious from human to human. Measles is a highly contagious disease that spreads rapidly through populations, so it can potentially be modeled accurately using a Hawkes model. Chlamydia is a sexually transmitted disease that is not as highly contagious as measles since the level of contact needed for exposure is much higher than for measles. Lyme disease is non-contagious from human to human but cases tend to be highly clustered, as the disease is primarily spread through ticks, and this exposure is much more likely to happen during warmer weather. Further, the test is applied to data on adolescent suicides in the United States, in order to investigate the hypothesis that such suicides are an epidemic spread by social contagion. The results show that the test is able to measure the degree of contagion of a disease, and the results suggest that there is indeed a small but statistically significant element of contagion to youth suicides.

Personal Circumstances Preceding Firearm Suicide Death Among Black Adults in the United States.

Despite an alarming rise in firearm suicide rates within Black communities, there has been little research on the contributors that precede firearm suicide deaths among Black adults. To fill this knowledge gap, this study was guided by an overarching research question: What are the recurring and salient personal circumstances experienced by Black adults prior to dying by firearm suicide in the US? This basic, interpretive qualitative study analyzed narrative text data for 843 Black adult firearm suicide decedents from the National Violent Death Reporting System. The analysis began with an initial cycle of open coding, followed by a second coding cycle, organizing the circumstances into major categories using a focused coding process. The analysis then moved back and forth between description and interpretation, and major themes were developed. Five themes emerged from this analysis: (1) Decedents often experienced poor health prior to death - but not always poor mental health. (2) Romantic relationships were often deteriorating, leading to frequent interpersonal arguments. (3) Alcohol and substance use were common before a suicide attempt. (4) Decedents frequently experienced financial and legal difficulties prior to death. (5) Decedents had many pathways to accessing firearms, and limiting firearmavailability before death was challenging. Additional research on potential intervention pathways will be critical, given recent evidence indicating dramatic increases in firearm ownership among Black adults over the past 5years.

Adolescent Firearm Suicides in the United States: Exploring Racial and Ethnic Differences, 2004 to 2020

Firearm suicides among adolescents have increased in the US and rates vary across racial and ethnic groups. In this study, we examined contextual information around adolescent firearm suicides and analyzed how incident characteristics vary across racial and ethnic groups. We analyzed firearm suicides among adolescents (ages 10–18 years) from 2004 to 2020 using data from the National Fatality Review-Case Reporting System (NFR-CRS). There were 4,153 firearm suicides during that period. Suicides often involved males, older adolescents (15–18 years), and handguns. Most firearms belonged to the primary caregiver and incidents frequently occurred at home. However, we found that characteristics varied substantially across racial and ethnic groups. Overall, we provide new information on firearm suicides among adolescents in the US using a larger dataset than previous studies and found significant differences in characteristics and demographics across racial and ethnic groups. This finding suggests the need for tailored prevention strategies.

Examining the Impact of Minimum Handgun Purchase Age and Background Check Legislation on Young Adult Suicide in the United States, 1991-2020.

Objectives. To examine the independent and joint effects of state legislation on minimum age for purchasing handguns and background checks on the suicide of young adults aged 18 to 20 years. Methods. We used negative binomial regressions with fixed effects for year and generalized estimating equations for state to estimate the effects of state legislation on annual counts of firearm, nonfirearm, and total young adult suicides in all 50 US states from 1991 to 2020. Results. Minimum age laws decreased the incidence rate of firearm suicide among young adults, an effect that was amplified in states with permit to purchase laws; there was no effect on the nonfirearm or total suicide rate. Permit to purchase laws significantly decreased the young adult firearm suicide incidence rate by 39% (incidence rate ratio [IRR] = 0.61; 95% confidence interval [CI] = 0.51, 0.74) and the overall suicide incidence rate by 14% (IRR = 0.86; 95% CI = 0.75, 0.99), with no effect on the nonfirearm suicide rate. Conclusions. Permit to purchase laws are a more promising avenue for reducing young adult suicides than are age-based restrictions.

Substitution of Methods in Suicide Deaths - Firearm Injury and Hanging.

Background: Prevention strategies for suicide emphasize restrictions on firearm access. These restrictions may lose efficacy if individuals substitute other lethal suicide methods. Aims: The objective of this study is to determine the extent to which individuals who die by suicide in the United States substitute hanging for firearm injury. Methods: This study is a repeated cross-sectional analysis of suicide deaths in the United States from 2003 to 2021. Multiple regression was used to estimate the effect of firearm access proxies on individual suicide methods (hanging vs. firearm injury). Results: The probability of death by hanging was significantly and negatively associated with proxies of firearm access. Limitations: This study does not compare crude rates of suicide by state, which rise on average with rates of firearm ownership. The National Violent Death Reporting System expanded over the sample period, so early years have incomplete ascertainment. Rates of gun ownership and gun safety law scales are measured as proxies. Conclusions: Although means restriction around firearm access is a critical tool for suicide prevention, complementary strategies for prevention around hanging merit further study.

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

IntroductionFew 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 (U.S.) with higher-than-expected veteran suicide rates and determine county-level social and economic characteristics associated with areas of higher risk. MethodsUsing 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. ResultsRisk 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 RR=1.065 [95%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]). ConclusionsThis 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.

Examining the Etiology of Asian American Suicide in the United States.

Research highlights racial and ethnic disparities in suicide, but Asian American suicide receives very little attention in the literature. This is the first comprehensive, large-scale, nationally representative study of completed suicide among Asian Americans in the United States. Descriptive and multilevel regression techniques compared the risk factors for completed suicide across 227,786 Asian American, White, African American, Hispanic, and American Indian suicide decedents from 2003 to 2019. Results indicated that Asian American suicide decedents were significantly less likely than their counterparts to have several risk factors for suicide. Asian Americans were less likely to be male, uneducated, and unmarried. Asian Americans were less likely to use alcohol and drugs, to have mental health problems, and to die by firearm, relative to other suicide methods. Asian Americans were less likely to have a history of prior suicide attempts, to have intimate partner problems, and to have criminal legal problems. Conversely, Asian Americans were more likely to reside in places with higher levels of concentrated disadvantage, residential instability, racial and ethnic heterogeneity, and population density. The results underscore the need for race-specific suicide prevention strategies that, for Asian Americans in particular, take into account cultural values and barriers to help-seeking behavior.

Trends in cancer-related suicide in the United States: a population-based epidemiology study spanning 40 years of data

Large cohort studies examining trends in cancer-related suicide are lacking. We analyzed data from the Surveillance, Epidemiology, and End Results (SEER) database, encompassing a total of 4,870,410 patients diagnosed with cancer from 1975 to 2017 in the United States. Joinpoint regression was used to estimate the annual percent change (APC) and average annual percentage change (AAPC) of age-adjusted rates of suicide. In the past 40 years, we revealed a gradual increase in cancer-related suicide rates from 1975 to 1989, followed by a gradual decrease from 1989 to 2013, and a marked decrease from 2013 to 2017. These trends suggested the potential impact of advancements in psychosocial care for patients with cancer in contributing to the observed decrease in suicide rates.

Why did peri-pandemic suicide death rates decrease among non-Hispanic white people while increasing among most people of color?

While suicides in the United States decreased during the COVID-19 pandemic, statistically significant decreases have been limited to White people throughout a large portion of 2020. This paper outlines possible explanations for racial/ethnic differences in suicidality in the early pandemic phases. We propose both distal (i.e., tele-mental health usage, internet and technology access, employment protections, and economic security) and proximal (cultural beliefs, coping strategies, clustering, pulling together, and embracing life) factors that may have helped build and foster community and mental wellness. However, this paper argues these factors did not extend, or did not extend as much, to many communities of color. We argue that these disparities are due to the myriad effects of discrimination and systemic racism, encapsulated broadly by the minority stress theory, and provide suggestions for relief and research.

Trends in Adolescent Suicide by Method in the US, 1999-2020

Adolescent suicide in the US is a major public health problem, yet temporal trends in suicide methods by demographics are understudied. To examine national trends in suicide mortality by method (firearm, poisoning, hanging and asphyxiation, and all other means) from 1999 to 2020 by demographic characteristics. This serial cross-sectional study used national death certificate data of adolescent (aged 10-19 years) suicide decedents compiled by the National Center for Health Statistics from January 1, 1999, to December 31, 2020. Data analysis was performed from April 1, 2023, to July 9, 2023. Age, sex, and race and ethnicity. Trends in age-standardized mortality rates and average annual percent change (AAPC) in rates were estimated by age, sex, and race and ethnicity for each suicide method. This study assessed data from 47 217 adolescent suicide decedents. From 1999 to 2020, suicide by firearm (AAPC, 1.0; 95% CI, 0.1-1.9), poisoning (AAPC, 2.7; 95% CI, 1.0-4.4), hanging and asphyxiation (AAPC, 2.4; 95% CI, 0.2-4.6), and other means (AAPC, 2.9; 95% CI, 1.2-4.6) increased. Rapidly increasing rates were observed among female adolescents for poisoning (AAPC, 4.5; 95% CI, 2.3-6.7) and hanging and asphyxiation (AAPC, 5.9; 95% CI, 5.0-6.8) suicides. From 2007 to 2020, firearm suicides sharply increased among female (annual percent change [APC], 7.8; 95% CI, 6.0-9.5) and male (APC, 5.3; 95% CI, 4.3-6.3) adolescents. Firearm suicide rates increased among Black adolescents from 2012 to 2020 (APC, 14.5; 95% CI, 9.7-19.5), Asian and Pacific Islander adolescents from 2008 to 2020 (APC, 12.0; 95% CI, 9.7-14.5), American Indian and Alaska Native adolescents from 2014 to 2020 (APC, 10.6; 95% CI, 2.6-19.3), and Hispanic or Latino adolescents from 2011 to 2020 (APC, 10.2; 95% CI, 6.3-13.8). During the study period, Black adolescents had the highest average increase in hanging and asphyxiation suicides (AAPC, 4.2; 95% CI, 3.2-5.2). From 2011 to 2020, poisoning suicide deaths increased (APC, 12.6; 95% CI, 8.5-16.7) among female adolescents. Suicide rates increased across all methods from 1999 to 2020. Differences were noted by sex, age, and race and ethnicity. Increasing suicide rates among racial and ethnic minoritized youth are especially concerning, and effective prevention strategies are urgently needed.

Pediatric suicide: Review of a preventable tragedy

Concepts of suicide are explored in this issue with a focus on suicide in children and adolescents. The epidemiology of pediatric suicide in the United States is reviewed; also, risk and protective factors, as well as prevention strategies, are discussed. Suicide in the pediatric athlete and the potential protective effect of exercise are examined. In addition, this analysis addresses the beneficial role of psychological management as well as current research on pharmacologic treatment and brain stimulation procedures as part of comprehensive pediatric suicide prevention. Though death by suicide in pediatric persons has been and remains a tragic phenomenon, there is much that clinicians, other healthcare professionals, and society itself can accomplish in the prevention of pediatric suicide as well as the management of suicidality in our children and adolescents.

APA moves to promote safe firearm storage, suicide prevention

Recognizing the urgent need to address the high prevalence of firearm‐related suicides in the United States, the American Psychological Association's (APA) governing Council of Representatives approved on Feb. 24, by a vote of 157–6, a resolution aimed at promoting secure firearms storage practices. This resolution underscores the critical role that psychologists and health care providers can have in preventing suicides by advocating for secure firearm storage and safety strategies, APA officials stated.

Disparities Among Pediatric Firearm Suicides in the United States: An Analysis of the National Violent Death Reporting System, 2014 to 2018.

Suicide is a leading cause of death in the United States (U.S.), with firearms being the predominant method. This study examines the racial disparity and disproportionality of pediatric firearm suicide from 2014 to 2018 in 17 U.S. states. We used the National Violent Death Reporting System to quantify the burden of pediatric firearm suicide by race/ethnicity and gender and assessed themes among decedents aged 10 to 17 years. Racial disparity and disproportionality were measured using the Disparity Index and Disproportionality Representation Index, respectively. Decedents were primarily non-Hispanic White (NHW, 77.5%) and male (84.0%). NHW children died at a rate that was 1.3 times greater than expected based on their proportion in the general population and were 2.6 times more likely to die by firearm suicide than non-Hispanic Black (NHB) children. NHB children were less likely to disclose suicide intention, suggesting that this group may require more active screening intervention. Qualitative analysis revealed unsafe firearm storage as a common theme among these deaths. Differences in age with respect to social media use and precipitating factors such as bullying and arguments with parents were also identified as contributing factors. Results of this study support the expansion of interventions such as lethal means restriction counseling and implementation of safer firearm storage laws.

National Trends in Suicides and Male Twin Live Births in the US, 2003 to 2019: An Updated Test of Collective Optimism and Selection in Utero.

Prior research based on Swedish data suggests that collective optimism, as measured by monthly incidence of suicides, correlates inversely with selection in utero against male twins in a population. We test this finding in the US, which reports the highest suicide rate of all high-income countries, and examine whether monthly changes in overall suicides precede changes in the ratio of male twin to male singleton live births. Consistent with prior work, we also examine as a key independent variable, suicides among women aged 15-49 years. We retrieved monthly data on suicides and the ratio of male twin to singleton live births from CDC WONDER, 2003 to 2019, and applied Box-Jenkins iterative time-series routines to detect and remove autocorrelation from both series. Results indicate that a 1% increase in monthly change in overall suicides precedes a 0.005 unit decline in male twin live births ratio 6 months later (coefficient = -.005, p value = .004). Results remain robust to use of suicides among reproductive-aged women as the independent variable (coefficient = -.0012, p value = .014). Our study lends external validity to prior research and supports the notion that a decline in collective optimism corresponds with greater selection in utero.

The lifeline and advanced practice nursing/intervention prevention perspective

The 988 Suicide and Crisis Lifeline (hereinafter referred to as The Lifeline) is a national effort to provide mental health crisis support for individuals or 3rd parties (requesting help for others) via a three-digit phone number. Since July 2022, the Lifeline is part of a national effort to assist individuals who are suicidal, homicidal, or distressed. Over half of suicides in the United States are completed with a gun, hence the need for an effort to focus on prevention related to a growing tragic loss of life. Psychiatric mental health nurses can be part of the prevention focus by promoting and discussing The Lifeline resource with patients, families, and colleagues. The majority of individuals requiring psychiatric-mental health services are living in the community and not institutionalized; therefore, The Lifeline is an invaluable resource to support wellness and well-being.

Suicide among Cancer Patients: Current Knowledge and Directions for Observational Research.

Cancer is a major public health concern associated with an increased risk of psychosocial distress and suicide. The reasons for this increased risk are still being characterized. The purpose of this study is to highlight existing observational studies on cancer-related suicides in the United States and identify gaps for future research. This work helps inform clinical and policy decision-making on suicide prevention interventions and ongoing research on the detection and quantification of suicide risk among cancer patients. We identified 73 peer-reviewed studies (2010-2022) that examined the intersection of cancer and suicide using searches of PubMed and Embase. Overall, the reviewed studies showed that cancer patients have an elevated risk of suicide when compared to the general population. In general, the risk was higher among White, male, and older cancer patients, as well as among patients living in rural areas and with lower socioeconomic status. Future studies should further investigate the psychosocial aspects of receiving a diagnosis of cancer on patients' mental health as well as the impact of new treatments and their availability on suicide risk and disparities among cancer patients to better inform policies.

Geographic Variation, Economic Activity, and Labor Market Characteristics in Trajectories of Suicide in the United States, 2008-2020.

Suicide rates in the United States have increased over the past 15 years, with substantial geographic variation in these increases; yet there have been few attempts to cluster counties by the magnitude of suicide rate changes according to intercept and slope or to identify the economic precursors of increases. We used vital statistics data and growth mixture models to identify clusters of counties by their magnitude of suicide growth from 2008 to 2020 and examined associations with county economic and labor indices. Our models identified 5 clusters, each differentiated by intercept and slope magnitude, with the highest-rate cluster (4% of counties) being observed mainly in sparsely populated areas in the West and Alaska, starting the time series at 25.4 suicides per 100,000 population, and exhibiting the steepest increase in slope (0.69/100,000/year). There was no cluster for which the suicide rate was stable or declining. Counties in the highest-rate cluster were more likely to have agricultural and service economies and less likely to have urban professional economies. Given the increased burden of suicide, with no clusters of counties improving over time, additional policy and prevention efforts are needed, particularly targeted at rural areas in the West.
