Abstract
The spread of suicidal behavior among individuals is often described as a contagion; however, rigorous modeling of suicide as a dynamic, contagious process is minimal. Here, we develop and validate a model-inference system depicting suicide ideation and death and use it to quantify the contagion processes in the US associated with two prominent celebrity suicide events: Robin Williams during 2014 and Kate Spade and Anthony Bourdain, which occurred 3 days apart during 2018. We show that both events produced large transient increases of suicide contagion contact rates, i.e., the spread of suicidal thought and behavior, and a period of elevated suicidal ideation in the general population. Our modeling approach provides a framework for quantifying suicidal contagion and better understanding, preventing, and containing its spread.

Healthcare (Basel) 2024; 12:1315. [PMID: 38998849 PMCID: PMC11241211 DOI: 10.3390/healthcare12131315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 06/08/2024] [Accepted: 06/21/2024] [Indexed: 07/14/2024] Open
Abstract
Objectives: This study aimed to analyze the association between alcohol use disorder (AUD) and suicidal ideation (SI) in the general Korean population. Methods: The 2022 Mental Health Awareness Survey was collected from the Chungcheongnam-do Mental Health Welfare Center (CHMHC). Before Propensity Score Matching (PSM), 823 participants were included in this study. After 1:4 PSM, the 255 participants were analyzed using the chi-square test and matched conditional logistic regression. Results: The AUD group had higher odds of experiencing SI than the non-AUD (adjusted odds ratio [AOR]: 2.40, 95% confidence intervals [CI]: 1.10-5.22). Stratified matched conditional logistic regression showed that, among the female, <40 years and single group, the AUD group was more likely to experience SI compared with the non-AUD, respectively (AOR:3.53, 95% CI: 1.20-10.44/AOR:3.45, 95% CI: 1.03-11.55/AOR:4.83, 95% CI: 1.18-19.69). However, among the male, ≥40 years and married group, we discovered no association between AUD and SI. Conclusions: Through this study, we found a strong association between the AUD group and SI. This association was particularly strong among female, <40 years, and single groups. This study elucidates the relationship between AUD and SI in the Chungnam region, which had not been previously identified in Korea, and it is expected to serve as foundational data for reducing the high suicide rate in this region. However, due to the limitation of being a cross-sectional study, future longitudinal research is required.

Abstract
OBJECTIVE Suicide ideation is the first stage of suicide behavior, and the long-term course of suicide ideation is highly variable. The aim of this study is to identify trajectories of suicide ideation over an 8-year period and explore the association of socioeconomic status (SES) with suicide ideation trajectories. METHODS We included 10,017 participants from Waves 7-15 of the Korea Welfare Panel Study; these have data on suicidal ideation (2012-2020). Trajectories analysis was conducted to identify distinct trajectories of suicidal ideation. Multinomial logistic regression was used to examine associations of SES with suicidal ideation trajectories. The interaction effects between current SES and prospective economic condition on trajectories were examined using a synergy index (SI). RESULTS We identified three suicide ideation trajectory groups: low-stable, moderate-decreasing, and high-persistent. Individuals in both moderate-decreasing and high-persistent trajectories had poorer current SES and prospective economic conditions than low-stable trajectories. Interestingly, those reporting poorer prospective economic conditions had a greater risk of being in a high-persistent trajectory than being in a moderate-decreasing trajectory. Further, individuals with poorer current SES and prospective economic conditions were more likely to be in the high-persistent trajectory. CONCLUSIONS Our findings demonstrated three distinct trajectories of suicide ideation which provide useful information for specific preventive interventions that could be developed. Moreover, poor prospective economic condition is a significant predictor of the high-persistent suicide ideation trajectory. Supporting economic difficulties and helping make goals and plans to strengthen positive thinking would help attenuate suicidal ideation and prevent suicidal behavior.

Abstract
This study aimed to investigate the association between suicide ideation and health-related behaviors and preventive health service use behaviors. We used data from the 2017 Korea National Health and Nutrition Examination Survey (KNHANES), a nationally representative survey. The final sample included 4486 participants aged 40 years or older. Preventive health behaviors were assessed for smoking, high-risk drinking, physical activities, regular meal intake, influenza vaccination, general health examination, and cancer screening. Logistic regression was used to examine the association between suicide ideation and preventive health behaviors with a series of adjustments for covariates. In general, suicide ideation was associated with unfavorable outcomes of preventive health behaviors, except for flu vaccination. For example, the adjusted prevalence of suicide ideation and non-suicide ideation groups were 54.3% vs. 43.7% for flu vaccination, 23.1% vs. 41.6% for physical activity, and 24.8% vs. 18.6% for high-risk alcohol drinking. After adjustment for covariates, the associations of suicide ideation with behaviors remained significant for physical activity (OR 0.52, 95% CI 0.34-0.81) and high-risk alcohol drinking (OR 2.22, 95% CI 1.34-3.69). Suicide ideation leads to the disruption of self-management of health behaviours, especially for physical activity and high-risk alcohol drinking, independently of depressive feelings.

Abstract
This study aims to identify the risk factors of suicidal ideation (SI) in a large sample of Chinese adults in the labour force. A total of 4136 eligible participants in the labour force were recruited from the routine health check-up cohort. Univariate and multivariate logistic regression were used to identify the factors associated with 12-month and lifetime SI. 175 (4.2%) subjects reported SI in the past twelve months, and 223 (5.4%) reported SI during their lifetime. The results showed that being divorced or widowed, religious belief, personal history of chronic disease and mental illness, family history of mental illness and suicide, and self-assessed childhood happiness were associated with both 12-month and lifetime SI. Additional associations were found between 12-month SI and the following factors: working overtime frequently, low monthly income, and having bachelor's degree. Moreover, being single is a risk factor of lifetime SI while not significant for 12-month SI. The present study identified several risk factors of 12-month and lifetime SI, which could potentially help develop targeted interventions for high-risk suicidal Chinese adults in the labour force.

J Affect Disord 2017; 207:291-299.

Abstract
BACKGROUND College students are a worldwide increasing group of young people at risk for suicidal thoughts and behaviours (STB). However, no previous studies have prospectively investigated the first onset of STB during the college period. METHODS Using longitudinal data from the Leuven College Surveys, 2337 (response rate [RR]=66.6%) incoming freshmen provided baseline data on STB, parental psychopathology, childhood-adolescent traumatic experiences, 12-month risk for mental disorders, and 12-month stressful experiences. A total of 1253 baseline respondents provided data on 12-month STB in a two-year annual follow-up survey (conditional RR=53.6%; college dropout adjusted conditional RR=70.2%). RESULTS One-year incidence of first-onset STB was 4.8-6.4%. Effect sizes of the included risk factors varied considerably whether viewed from individual-level (ORs=1.91-17.58) or population-level perspective (PARPs=3.4-34.3%). Dating violence prior to the age of 17, physical abuse prior to the age of 17, and 12-month betrayal by someone else than the partner were most strong predictors for first-onset suicidal ideation (ORs=4.23-12.25; PARPs=8.7-27.1%) and plans (ORs=6.57-17.58; PARPs=15.2-34.3%). Multivariate prediction (AUC=0.84-0.91) revealed that 50.7-65.7% of first-onset STB cases were concentrated in the 10% at highest predicted risk. LIMITATIONS As this is a first investigation of STB onset in college, future studies should use validation samples to test the accuracy of our multivariate prediction model. CONCLUSIONS The first onset of STB in college appears to be higher than in the general population. Screening at college entrance is a promising strategy to identify those students at highest prospective risk, enabling the cost-efficient clinical assessment of young adults in college.
