Objective

College entrance may be a strategically well-placed “point of capture” for detecting late adolescents with suicidal thoughts and behaviors (STB). However, a clear epidemiological picture of STB among incoming college students is lacking. We present the first cross-national data on prevalence as well as socio-demographic and college-related correlates for STB among first-year college students.

Method

Web-based self-report surveys were obtained from 13,984 first-year students (response rate 45.5%) across 19 colleges in 8 countries (Australia, Belgium, Germany, Mexico, Northern Ireland, South Africa, Spain, and the United States).

Results

Lifetime prevalence of suicidal ideation, plans, and attempts was 32.7%, 17.5%, and 4.3%, respectively. The 12-month prevalence was 17.2%, 8.8%, and 1.0%, respectively. About three-fourths of STB cases had onset before the age of 16 years (Q3 = 15.8), with persistence figures in the range of 41% to 53%. About one-half (53.4%) of lifetime ideators transitioned to a suicide plan; 22.1% of lifetime planners transitioned to an attempt. Attempts among lifetime ideators without plan were less frequent (3.1%). Significant correlates of lifetime STB were cross-nationally consistent and generally modest in effect size (median adjusted odds ratio [aOR] = 1.7). Nonheterosexual orientation (aOR range 3.3−7.9) and heterosexual orientation with some same-sex attraction (aOR range 1.9−2.3) were the strongest correlates of STB, and of transitioning from ideation to plans and/or attempts (aOR range 1.6−6.1).

Conclusion

The distribution of STB in first-year students is widespread, and relatively independent of socio-demographic risk profile. Multivariate risk algorithms based on a high number of risk factors are indicated to efficiently link high-risk status with effective preventive interventions.

一年级大学生的自杀思想和行为：WMH-ICS项目的结果

客观的

大学入学可能是战略上合适的“捕捉点”，用于发现有自杀念头和行为的青少年（STB）。然而，缺乏对即将到来的大学生的机顶盒流行病学的清晰描述。我们提供了关于大一新生的机顶盒患病率以及社会人口统计学和大学相关指标的第一个跨国数据。

方法

基于网络的自我报告调查是从8个国家（澳大利亚，比利时，德国，墨西哥，北爱尔兰，南非，西班牙和美国）的19所大学的13984名一年级学生（答复率为45.5％）获得的。

结果

自杀意念，计划和尝试的终生患病率分别为32.7％，17.5％和4.3％。12个月患病率分别为17.2％，8.8％和1.0％。大约四分之三的STB病例在16岁之前发病（Q3 = 15.8），持续性数字在41％到53％之间。一生中有大约一半（53.4％）的思想家转变为自杀计划；22.1％的终身规划人员已过渡到尝试。一生中没有计划的思想家的尝试频率较低（3.1％）。生命周期机顶盒的重要相关性在全国范围内是一致的，并且效应大小通常适中（中位调整比值比[aOR] = 1.7）。非异性恋取向（aOR范围3.3-7.9）和具有同性吸引的异性恋取向（aOR范围1.9-2.3）是机顶盒的最强相关性，

结论

一年级学生中STB的分布广泛，并且相对独立于社会人口统计学风险状况。指出了基于大量风险因素的多元风险算法，可以有效地将高风险状态与有效的预防措施联系起来。
