Racial Disparities in Spatial and Temporal Youth Suicide Clusters

Race, Rurality, and Suicidality in Children and Adolescents

INTRODUCTION

Suicide is among the leading causes of death in U.S. youth. Rural residency is a risk factor, but suicide variability by race/ethnicity is more nuanced. Early detection of suicidal ideation and intent are key components of prevention, but to the authors' knowledge, few prior studies have examined how rurality and race interact on youth suicidality. This study examined suicidality between White non-Hispanic versus non-White or Hispanic youth, as well as those who lived in rural versus non-rural areas.

METHODS

Cross-sectional analyses were conducted using data from youth age 5-17 years who had complete capture of their medical care in a Wisconsin healthcare system. Suicidality was extracted from medical records by screening for diagnoses indicative of suicidal attempt or ideation between 2017 and 2022. Race/ethnicity and rural residence were extracted from administrative records. Analyses were done in 2023.

RESULTS

The sample included 27,392 rural and 20,370 non-rural youth, with suicidality observed in 2% of participants. There was a significant interaction between rural residence and race/ethnicity (p=0.015). Non-White or Hispanic youth in rural areas had the highest risk of suicidality at 75 (CI: 57, 97) per 10,000. Non-White or Hispanic youth in non-rural areas had the lowest risk of suicidality at 38 (CI: 28, 52) per 10,000.

CONCLUSIONS

Racial/ethnic minority youth who lived in rural areas were more likely to experience suicidality as compared to their non-rural counterparts. Larger prospective studies are needed to identify causal elements of the rural environment that may hasten racial disparities in youth suicidality.

Spatial-temporal analysis of suicide clusters for suicide prevention in Hong Kong: a territory-wide study using 2014-2018 Hong Kong Coroner's Court reports

Background

This study aimed to (i) identify high-risk suicide-methods clusters, based on location of residence and suicide incidence; and (ii) compare the characteristics of cases and spatial units inside and outside clusters.

Methods

Suicide data of 4672 cases was obtained from the Coroner's Court reports in Hong Kong (2014-2018). Monthly aggregated suicide numbers based on location of residence, and suicide incidence, were obtained in small tertiary planning units (STPUs). Community-level characteristics and population of STPUs were retrieved from 2016 Census. Retrospective space-time analyses were performed to identify locations with elevated suicide rates over specific time periods, i.e., spatial-temporal clusters. Clusters were evaluated for overall suicide (any method), as well as jumping, hanging, and charcoal burning methods, in location of residence and suicide incidence. Bi-variate analysis was performed to compare the characteristics of cases, and spatial units, inside and outside the clusters.

Findings

Suicide clusters involving jumping and charcoal burning were identified, but no hanging clusters were found. The within-cluster distribution of types of housing was different from that of outside. For most of the overall suicide and suicide by jumping clusters, spatial units within the clusters were more socially disadvantaged compared to those outside.

Interpretation

Clusters varied by suicide methods, location of residence and location of incidence. The findings highlighted the need for consistent and concerted support from different stakeholders within suicide clusters, to ensure appropriate design, implementation and sustainability of effective suicide prevention programs.

Responding to Suicide in School Communities: An Examination of Postvention Guidance from Expert Recommendations and Empirical Studies

PURPOSE OF REVIEW

We review the published literature on a school's response after a student dies by suicide ("postvention"). We examine published recommendations based on expert guidance and empirical studies that have evaluated postvention measures.

RECENT FINDINGS

Experts recommend careful communication with family, staff, and students that adheres to published suicide reporting guidelines. Experts also emphasize the importance of identifying and supporting high-risk students. Few robust, controlled studies have identified effective postvention measures. Effective measures tended to occur in group settings (e.g., group therapy), focus on improving grief symptoms, and involve mental health professionals. Postvention has not been robustly studied in the school context. Expert recommendations and a few evidence-backed studies provide the frame for a coherent, school-based postvention response. Further research is needed to strengthen and expand our collective understanding of effective postvention measures in the school context as youth suicide attempts continue to rise.

Editors' Best of 2022

There is, in the content of the Journal, an embarrassment of riches, and picking a "best" seems to demand a certain qualification: is the "best" the most interesting, most surprising, most educational, most important, most provocative, most enjoyable? How to choose? We are hardly unbiased and can admit to a special affection for the ones that we and the authors worked hardest on, hammering version after version into shape. Acknowledging these biases, here are the 2022 articles that we think deserve your attention or at least a second read.

Perceived racial discrimination and suicidal behaviors among racial and ethnic minority adolescents in the United States: Findings from the 2021 adolescent behaviors and experiences survey

The objectives of this study were to investigate: (1) the prevalence of perceived racial discrimination (PRD) in school, among racial/ethnic minority adolescents, and (2) the association between PRD and suicidal behaviors among racial/ethnic minority adolescents in the United States. Data from a sample of 3241 racial/ethnic minority adolescents (53.7% female) from the 2021 Adolescent Behaviors and Experiences Survey were analyzed using binary logistic regression. Controlling for other factors, racial/ethnic minority adolescents who experienced PRD had 1.57 times higher odds of experiencing suicidal ideation (adjusted odds ratio (AOR) = 1.57, 95% Confidence Intervals (CI) = 1.09-2.25), 1.64 times higher odds of making a suicide plan (AOR = 1.64, 95% CI = 1.09-2.49), and 1.67 times higher odds of attempting suicide (AOR = 1.67, 95% CI = 1.04-2.68) during the past year. Other factors associated with suicidal behaviors included self-identifying as lesbian/gay, bisexual, or other/questioning; experiencing cyberbullying; feeling sad or hopeless; and poor mental health during the pandemic. The findings of this study extend past research and demonstrate that racial/ethnic minority adolescents who experienced PRD were more likely to report suicidal behaviors over and above other well-established risk factors for suicidal behaviors. Future studies that employ longitudinal designs are needed to elucidate mechanisms underlying these associations.
