The aim of this study was to analyze whether individuals reporting exposure to workplace bullying had a higher risk of suicidal behavior, including both suicide attempt and death by suicide, than those not reporting such exposure.
Using a prospective cohort study design, we linked data from nine Danish questionnaire-based surveys (2004-2014) to national registers up to 31 December 2016. Exposure to workplace bullying was measured by a single item. Suicide attempts were identified in hospital registers and death by suicide in the Cause of Death Register. Among participants with no previous suicide attempts, we estimated hazard ratios (HR) and 95% confidence intervals (CI), adjusting for sex, age, marital status, socioeconomic status, and history of psychiatric morbidity.
The sample consisted of 98 330 participants (713 798 person-years), 63.6% were women, and the mean age was 44.5 years. Of these participants, 10 259 (10.4%) reported workplace bullying. During a mean follow-up of 7.3 years, we observed 184 cases of suicidal behavior, including 145 suicide attempts, 35 deaths by suicide and 4 cases that died by suicide after surviving a suicide attempt. The fully-adjusted HR for the association between workplace bullying and suicidal behavior was 1.65 (95% CI 1.06-2.58). The HR for suicide attempts and death by suicide were 1.65 (1.09-2.50) and 2.08 (0.82-5.27), respectively. Analyses stratified by sex showed a statistically significant association between workplace bullying and suicidal behavior among men but not women.
The results suggest that exposure to workplace bullying is associated with an elevated risk of suicidal behavior among men.
本研究旨在分析报告曾遭受职场欺凌的个体发生自杀行为（包括自杀未遂和自杀死亡）的风险是否高于未报告此类经历的个体。
我们采用前瞻性队列研究设计，将来自丹麦 9 项基于问卷调查的研究（2004-2014 年）的数据与截至 2016 年 12 月 31 日的全国登记数据相链接。通过单项问题来测量职场欺凌暴露情况。医院登记处记录自杀未遂，死因登记处记录自杀死亡。在无既往自杀未遂史的参与者中，我们调整了性别、年龄、婚姻状况、社会经济地位和精神病史后，估计了危害比（HR）和 95%置信区间（CI）。
样本包括 98330 名参与者（713798 人年），其中 63.6%为女性，平均年龄为 44.5 岁。在这些参与者中，10259 人（10.4%）报告曾遭受职场欺凌。在平均 7.3 年的随访期间，我们观察到 184 例自杀行为，包括 145 例自杀未遂、35 例自杀死亡和 4 例自杀未遂后死亡。职场欺凌与自杀行为之间的完全调整 HR 为 1.65（95%CI 1.06-2.58）。自杀未遂和自杀死亡的 HR 分别为 1.65（1.09-2.50）和 2.08（0.82-5.27）。按性别分层的分析显示，职场欺凌与男性自杀行为之间存在统计学显著关联，但与女性无关。
研究结果表明，男性暴露于职场欺凌与自杀行为风险升高相关。
