OBJECTIVES
This study investigated the change in suicidal ideation and its risk factors among employees. A longitudinal cohort study was conducted, starting with the baseline online survey in March 2020 (T1), followed by May (T2), and August (T3). The change in suicidal ideation from T2 to T3 and relevant factors associated with suicidal ideation at T3 were examined. Suicidal ideation significantly increased between May and August 2020 among females, younger (under 39 years old), highly educated population, and those without pre-existing mental health conditions. Factors significantly associated with suicidal ideation were younger age, suicidal ideation at T2, and with pre-existing mental health conditions. Loneliness at T2 showed a significant association with suicidal ideation, if adjusting those without pre-existing mental health conditions. National and community support is needed to target people who are likely to be left behind, such as young people and those with pre-existing mental health conditions, in the pandemic.
METHOD
A longitudinal study was conducted with a cohort of full-time employees, starting with the baseline online survey in March 2020 (time point 1), followed by May (time point 2) and August (time point 3). The change in suicidal ideation from time point 2 to 3, and relevant factors associated with suicidal ideation at time point 3, were examined.
RESULTS
Suicidal ideation significantly increased between time points 2 and 3 among women, younger people (aged <39 years), those who were highly educated and those without pre-existing mental health conditions. Factors significantly associated with suicidal ideation were younger age, suicidal ideation at time point 2 and pre-existing mental health conditions. Loneliness at time point 2 showed a significant association with suicidal ideation when adjusting for those without pre-existing mental health conditions.
CONCLUSIONS
National and community support is needed to target people who are likely to be left behind, such as young people, those with pre-existing mental health conditions and those experiencing loneliness, in the COVID-19 pandemic.
目的
本研究调查了员工自杀意念的变化及其风险因素。开展了一项纵向队列研究，始于2020年3月的基线在线调查（T1），随后是5月（T2）和8月（T3）。研究了从T2到T3自杀意念的变化以及与T3时自杀意念相关的因素。2020年5月至8月期间，女性、年轻人（39岁以下）、高学历人群以及那些没有既往心理健康问题的人群的自杀意念显著增加。与自杀意念显著相关的因素是年龄较小、T2时的自杀意念以及既往有心理健康问题。如果对那些没有既往心理健康问题的人进行调整，T2时的孤独感与自杀意念存在显著关联。在疫情期间，需要国家和社区的支持，以关注那些可能被忽视的人群，如年轻人和那些有既往心理健康问题的人。
方法
对一组全职员工进行了纵向研究，始于2020年3月的基线在线调查（时间点1），随后是5月（时间点2）和8月（时间点3）。研究了从时间点2到3自杀意念的变化以及与时间点3时自杀意念相关的因素。
结果
在女性、年轻人（年龄<39岁）、高学历人群以及那些没有既往心理健康问题的人群中，时间点2和3之间自杀意念显著增加。与自杀意念显著相关的因素是年龄较小、时间点2时的自杀意念以及既往有心理健康问题。如果对那些没有既往心理健康问题的人进行调整，时间点2时的孤独感与自杀意念存在显著关联。
结论
在新冠疫情期间，需要国家和社区的支持，以关注那些可能被忽视的人群，如年轻人、有既往心理健康问题的人以及经历孤独的人。
