The coronavirus disease 2019 (COVID-19) pandemic is a major threat to the public. However, the comprehensive profile of suicidal ideation among the general population has not been systematically investigated in a large sample in the age of COVID-19.
A national online cross-sectional survey was conducted between February 28, 2020 and March 11, 2020 in a representative sample of Chinese adults aged 18 years and older. Suicidal ideation was assessed using item 9 of the Patient Health Questionnaire-9. The prevalence of suicidal ideation and its risk factors was evaluated.
A total of 56,679 participants (27,149 males and 29,530 females) were included. The overall prevalence of suicidal ideation was 16.4%, including 10.9% seldom, 4.1% often, and 1.4% always suicidal ideation. The prevalence of suicidal ideation was higher in males (19.1%) and individuals aged 18-24 years (24.7%) than in females (14.0%) and those aged 45 years and older (11.9%). Suicidal ideation was more prevalent in individuals with suspected or confirmed infection (63.0%), frontline workers (19.2%), and people with pre-existing mental disorders (41.6%). Experience of quarantine, unemployed, and increased psychological stress during the pandemic were associated with an increased risk of suicidal ideation and its severity. However, paying more attention to and gaining a better understanding of COVID-19-related knowledge, especially information about psychological interventions, could reduce the risk.
The estimated prevalence of suicidal ideation among the general population in China during COVID-19 was significant. The findings will be important for improving suicide prevention strategies during COVID-19.
2019 年冠状病毒病（COVID-19）大流行是对公众的重大威胁。然而，在 COVID-19 时代，尚未在大样本中系统研究一般人群中自杀意念的综合特征。
2020 年 2 月 28 日至 2020 年 3 月 11 日，在中国成年人代表性样本中进行了一项全国性在线横断面调查，年龄在 18 岁及以上。使用患者健康问卷-9 的第 9 项评估自杀意念。评估自杀意念的流行率及其危险因素。
共纳入 56679 名参与者（男性 27149 名，女性 29530 名）。自杀意念的总患病率为 16.4%，其中 10.9%为偶尔，4.1%为经常，1.4%为总是有自杀意念。男性（19.1%）和 18-24 岁的个体（24.7%）自杀意念的患病率高于女性（14.0%）和 45 岁及以上的个体（11.9%）。疑似或确诊感染（63.0%）、一线工作人员（19.2%）和有先前精神障碍的个体（41.6%）自杀意念更为普遍。在大流行期间经历检疫、失业和心理压力增加与自杀意念及其严重程度的风险增加相关。然而，更多地关注和更好地了解与 COVID-19 相关的知识，特别是有关心理干预的信息，可以降低风险。
在中国 COVID-19 期间，一般人群中自杀意念的估计患病率很高。这些发现对于改善 COVID-19 期间的自杀预防策略非常重要。
