Characteristics of interpersonal conflicts preceding youth suicide: analysis of data from the 2017 National Violent Death Reporting System

Gambling as a precipitating factor in deaths by suicide in the National Violent Death Reporting System

OBJECTIVES

The public health burden of gambling remains difficult to estimate, given the lack of relevant, available data. Death by suicide, represents a substantial and quantifiable public health cost. The current study reviews data from the National Violent Death Reporting System to detect cases where gambling was identified as a meaningful contextual factor to a death by suicide.

STUDY DESIGN

This study is an exploratory content analysis.

METHODS

We analysed narrative data from cases of death by suicide, collected from 2003 to 2020 recorded in the Restricted Access Data of the National Violent Death Reporting System. Gambling-related cases identified in our analysis were compared against all other cases on demographic characteristics, case characteristics, US state, and incident year. Chi-square tests of independence and the Wilcoxon ranked sum tests were used in bivariate comparisons.

RESULTS

Overall, 1306 of 296 317 cases were classified as gambling-related. This represented 0.44% of total cases. Gambling-related classification was over-represented among those identified as Asian (7.0% vs 2.2%) and under-represented among those identified as Black or African American (4.0% vs 6.4%) compared with all other deaths by suicide. Gambling-related cases were also over-represented in cases where alcohol use was suspected (28.0% vs 21.2%), where there were significant financial problems (50.3% vs 8.6%), where there were intimate partner problems (31.5% vs 25.6%), and under-represented in cases where there was a previous mental health diagnosis (35.1% vs 38.8%). The rate of gambling-related cases in Nevada was approximately nine times greater than the rate in the overall sample (4.0% vs 0.44%).

CONCLUSIONS

Administrative data can be used to study the impacts of gambling on public health in the absence of quality representative survey data. However, these sources are still likely to underestimate the public health burden of gambling with current structures and procedures. Requiring intentional collection of gambling-related information in cases of suicide would be a significant step towards better quantifying the public health burden of gambling in the United States.

Age, period and cohort analysis of suicide trends in Australia, 1907-2020

Background

Suicide rates have been increasing in Australia since the mid-2000s, especially for women aged ≤25 years. We conducted an age-period-cohort study to investigate these recent trends in the context of historical Australian suicide rates.

Methods

Data on annual suicides in Australia from 1907 to 2020 were extracted from the General Record of Incidence of Mortality. We modelled age-specific effects for a reference cohort, after adjustment for period effects.

Findings

We found evidence of age, cohort and period effects. For males, compared to the cohort born in 1946-1950, rates were higher for all cohorts born after this year. The period effect showed peaks in the risk of male suicide in the mid 1960s and the early 1990s, followed by a decline in risk until early 2010, after which the risk began to rise again. For females, compared to the cohort born in 1946-1950, the risk of suicide was higher for all cohorts born after this, with the highest risk for those born in 2006-2010. The period effect for females showed an elevated risk of suicide in the mid 1960s followed by a sharp decline, and an increase in risk after 2009.

Interpretation

Suicide rates in Australia have fluctuated substantially over time and appear to be related to age trends as well as period and cohort trends. Advocacy and policy making tends to focus on contemporaneous changes in suicide rates. However, this study shows that focusing only on year-on-year changes in suicide rates ignores underlying trends for specific population birth-cohorts.

Intergenerational conflicts and its impact on young people's suicidal behaviour: a scoping review

Familial factors have been studied to be an important risk factor for suicidal behaviour among young people. Within families, conflicts across generations have been found to have a significant impact on young people's mental health and wellbeing. This scoping review aimed to identify existing literature examining intergenerational conflicts and its association with suicidal behaviour among young people aged 10-24 years. English articles related to intergenerational conflicts, suicide, suicidal ideation, and suicidal behaviour in a familial context experienced by young people have been included. OVID, PubMed, and Scopus databases were searched using relevant search terms and articles were selected based on the inclusion and exclusion criteria. On database search, four articles met the inclusion criteria and four more were included based on cross-referencing. Overall, eight studies were including in the synthesis of results. Significant positive association between intergenerational conflicts and suicidal ideation and behaviour among adolescents and young adults has been elucidated from the scoping review. Age-specific differences have been noted in the experience of conflicts, with adolescents primarily facing conflicts related to academic performance and cell phone usage and older youth facing conflicts about financial independence and interpersonal relationships. Females have been found to experience more intergenerational conflict and higher associated distress than males.

Research utility and limitations of textual data in the National Violent Death Reporting System: a scoping review and recommendations

BACKGROUND

Many studies of injury deaths rely on mortality data that contain limited contextual information about decedents. The National Violent Death Reporting System (NVDRS) is unique among such data systems in that each observation includes both quantitative variables and qualitative texts (called "narratives") abstracted from original source documents. These narratives provide rich data regarding salient circumstances that can be used to inform prevention efforts. This review provides a comprehensive summary of peer-reviewed research using NVDRS narratives over the past 20 years, including the limitations of these texts and provides recommendations on utilizing and improving narrative quality for researchers and practitioners.

MAIN BODY

Studies that used narratives to examine deaths related to suicide, homicide, undetermined intent, accidental firearm, or legal intervention were identified by a title/abstract screening, followed by a full-text review. The search was conducted on English-language, peer-reviewed literature and government reports published from 2002 to 2022 in PubMed, PsycInfo, Scopus, and Google Scholar. Abstracted elements focused on the methodologies used to analyze the narratives, including approaches to explore potential biases in these texts. Articles were abstracted independently by two reviewers, with disagreements resolved through consensus discussion. During the 20-year period, 111 articles used narratives. Two-thirds studied suicide (n = 48, 43%) and homicides (n = 25, 23%). Most studies analyzed the narratives using manual review (n = 81, 73%) and keyword searches (n = 9, 8%), with only 6 (5%) using machine learning tools. Narratives were mainly used for case finding (n = 49, 44%) and characterization of circumstances around deaths (n = 38, 34%). Common challenges included variability in the narratives and lack of relevant circumstantial details for case characterization.

CONCLUSION

Although the use of narratives has increased over time, these efforts would be enhanced by detailed abstraction of circumstances with greater salience to injury research and prevention. Moreover, researchers and practitioners would benefit from guidance on integrating narratives with quantitative variables and standardized approaches to address variability in the completeness and length of narratives. Such efforts will increase the reliability of findings and set the stage for more widespread applications of data science methods to these texts.

Prevalence of and risk factors for depressive and anxiety symptoms in a large sample of Chinese adolescents in the post-COVID-19 era

BACKGROUND

Depressive and anxiety symptoms are widespread among adolescents today, creating a large social problem. However, few previous studies have addressed depression and anxiety among adolescents in Chinese cohorts. The aim of this study was to evaluate the prevalence of and risk factors for depressive and anxiety symptoms among Chinese middle school adolescent students in the post-COVID-19 era.

METHODS

A total of 22,380 middle school students from Jiangsu Province were surveyed online, and their general demographic data were collected. The Patient Health Questionnaire-9 (PHQ-9) was used to assess depressive symptoms, and the seven-item Generalized Anxiety Disorder (GAD-7) scale was used to measure anxiety symptoms.

RESULTS

Of these participants (aged 12-17 years), 25.6% had depressive symptoms, 26.9% had anxiety symptoms, and 20.6% had a combination of depression and anxiety symptoms. The prevalence of depressive symptoms was higher in female adolescents (27.6%) than in male adolescents (23.7%; χ² = 45.479, P = 0.000), and the proportion with anxiety symptoms was higher among female adolescents (28.6%) than among male adolescents (25.4%; χ² = 29.390, P = 0.000). Furthermore, binary logistic regression analysis showed that gender, region, and parental relationship were significantly associated with depressive symptoms among adolescents, while age, gender, region, and parental relationship were significantly associated with anxiety symptoms.

CONCLUSIONS

Our findings demonstrated that the prevalence of reported depressive and anxiety symptoms in Chinese adolescents are high. Female gender, urban region, and poor parental relationship may be risk factors for depressive and anxiety symptoms. Furthermore, policy makers, schools, and families need to pay more attention to the psychological health of adolescents, develop response plans and take early intervention measures to reduce the prevalence of adolescent depression and anxiety.
