Exposure to childhood adversities (CAs) is known to be associated with the onset of suicidal ideation and plans. However, little is known regarding the contribution of CAs to their persistence.
The study aims to examine the type, number and frequency of CA exposure on the persistence of suicidal ideation and plans at one-year.
Data were drawn from the French portion of the World Mental Health International College Student survey. At baseline (n = 2661, response rate = 7,58 %), exposure to 12 types of CAs prior to age 18, lifetime mental disorders, lifetime and 12-month suicidal ideation and plans were assessed. At one-year follow-up (n = 1221), 12-month mental disorders, suicidal ideation and plans were assessed. Among those with a prior history of suicidal ideation, logistic regressions were performed to examine the role of CAs on the persistence of ideation and plans at one-year.
At baseline, frequency and number of CAs were associated with 12-month suicidal ideation and plans. Among lifetime ideators, 49.6 % reported 12-month suicidal ideation at follow-up. Physical abuse was associated with an increased risk of suicidal ideation and plan persistence at one year in univariate analyses. However, CAs were not associated with the persistence of suicidal ideation and plans at one-year in multivariate analyses.
Retrospective report of CA exposure, and low baseline response rate.
Using a fine-grained operationalization of CA exposure, CAs were not involved in the persistence of suicidal ideation or plans, their deleterious effect more likely to occur early in the course of psychopathology.

Objectives: We want to test the association between carbon monoxide poisoning (CMP) experiencing and lifetime suicidal ideation/suicide plan among community residents. Methods: This is a population-based cross-sectional study conducted among community residents in Hebei province, China. We analyzed a total of 21,376 valid questionnaires. CMP experience and lifetime suicidal ideation/suicide plan were assessed in this study. Logistic regression and false discovery rate correction were conducted to analyze the associations and correct the p values. Results: We found that CMP (OR = 2.56, p < 0.001, corrected-p = 0.001) was associated with lifetime suicidal ideation, and the other risk factors were female (OR = 0.53, p < 0.001, corrected-p = 0.001). The association between CMP and suicide plan was not supported after false discovery rate correction (OR = 2.15, p = 0.035, corrected-p = 0.385). For the CMP patients, experiencing ≥2 times CMP (OR = 2.76, p = 0.001, corrected-p = 0.011) was also in higher risk of lifetime suicidal ideation. The association between CMP times and lifetime suicidal plan was not supported after false discovery rate correction (OR = 4.95, p = 0.021, corrected-p = 0.231). Conclusion: CMP patients are in higher risk of lifetime suicidal ideation. For CMP patients, some strategies are needed to control their suicidal ideation.

BACKGROUND: Although the association between sleep problems and suicidal behaviors were found in many studies, their associations are not built until now. One of the reasons may be the identified differences among different suicide behaviors, which also implied that sleep quality may play different roles on these suicidal behaviors. However, absent study explores the possible distinguishing associations between sleep quality and different suicidal behaviors.
METHODS: This is a population-based study conducted in Hebei province, China. Totally, 21,376 valid questionnaires were analyzed in this study. Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality. Suicidal behaviors, living alone, and social-demographic variables were assessed for all the participants.
RESULTS: The prevalence of suicidal ideation, plan, and attempt were 1.4%, 0.3%, and 0.2%, respectively. The PSQI scores were separately associated with suicidal ideation (OR=1.25, p<0.001), plan (OR=1.19, p<0.001), and attempt (OR=1.18, p<0.001). The similar results were also supported when we compared conditional suicidal behaviors with general population without any suicidal behaviors. However, when we compared suicide attempters with suicidal ideators (with or without suicide plan), the associations between PSQI scores and suicide attempt were not supported (OR=1.93, P>0.05 or OR=1.02, p>0.05).
CONCLUSIONS: The cross-sectional design made us cannot get any causal relationships. The self-reported sleep quality may also produce some influence on the results.
CONCLUSIONS: The results imply us that improving sleep quality may be not effective to control further suicidal behaviors, when people have considered or planned to suicide. The findings also can be translated into the clinical and preventive practice for suicide control.

Adverse childhood experiences (ACEs) are associated with increased suicidal behaviors in adolescents and most research has been restricted to certain types of or cumulative exposure to ACEs. Few studies have examined the association between patterns of ACEs and suicidal behaviors.
To identify the contributions of type and pattern of exposure to ACEs to suicidal behaviors and their gender differences among middle school students in China.
A school-based health survey was conducted in four provinces in China between 2017 and 2018. 14 500 students aged 10-20 years completed standard questionnaires, to record details of ACEs, suicide ideation, suicide plan, and suicide attempt.
Latent class analysis indicated four distinct patterns of ACEs exposure: high ACEs (6.3%), high abuse and neglect (21.4%), high neglect (45.5%), and low ACEs (26.8%). Logistic analyses showed that, compared with low ACEs, the high ACEs were more likely to report suicidal behaviors. No gender differences were found in the independent effects of ACEs type or pattern on suicidal behaviors, except for the emotional neglect associated with suicidal behaviors in girls than boys.
The study was cross-sectional and used self-reported questionnaires. Thus, it is difficult to establish a causal relationship between patterns of ACEs and suicidal behaviors.
Our findings addressed the need for a comprehensive consideration of ACEs in preventive healthcare work to identify children exposed to the most problematic ACE patterns. The study provided the evidence of targeted intervention to preempt the emergence of suicide behavior in at-risk students in adolescents.

Past suicide attempts are a significant risk factor for future suicidality. Therefore, the present military-based study examined the past suicidal behavior of soldiers who recently made a severe suicide attempt. Our sample consisted of 65 active-duty soldiers (61.5% males), between the ages of 18 and 28 years old (M = 20.4, SD ± 1.3). The inclusion criterion was a recent severe suicide attempt, requiring at least a 24 h hospitalization. This sample was divided into two groups, according to previous suicidal behavior, namely whether their first suicide attempt was before or after enlistment (n = 25; 38.5% and n = 40; 61.5%, respectively). We then examined the lethality and intent of the recent event in regard to this division. Four measures were used to assess the subjects\' suicidal characteristics: the Columbia Suicide Severity Rating Scale, the Self-Harm Behavior Questionnaire, the Suicidal Behaviors Questionnaire-Revised, and the Beck Scale for Suicide Ideation. No significant difference in the severity of the suicide attempts (either actual or potential severity) were found between those who had suicide attempts before enlistment and those who had their first attempt in the service. As a matter of fact, most of the suicide attempts that occurred for the first time during military service had used a violent method (58.3%, n = 21). Finally, using multivariate analyses, we found that current thoughts and behavior, rather than past suicidality, was the strongest predictor for the lethality of suicide attempts.
