Many Canadians report decreased mental health during the COVID-19 pandemic, and concerns have been raised about possible increases in suicide. This study investigates the pandemic's potential impact on adults' suicide ideation.
We compared self-reported suicide ideation in 2020 versus 2019 by analyzing data from the Survey on COVID-19 and Mental Health (11 September to 4 December 2020) and the 2019 Canadian Community Health Survey. Logistic regression was conducted to determine which populations were at higher risk of suicide ideation during the pandemic.
The percentage of adults reporting suicide ideation since the pandemic began (2.44%) was not significantly different from the percentage reporting suicide ideation in the past 12 months in 2019 (2.73%). Significant differences in the prevalence of recent suicide ideation in 2020 versus 2019 also tended to be absent in the numerous sociodemographic groups we examined. Risk factors of reporting suicide ideation during the pandemic included being under 65 years, Canadian-born or a frontline worker; reporting pandemic-related income/job loss or loneliness/isolation; experiencing a lifetime highly stressful/traumatic event; and having lower household income and educational attainment.
Evidence of changes in suicide ideation due to the pandemic were generally not observed in this research. Continued surveillance of suicide and risk/protective factors is needed to inform suicide prevention efforts.
许多加拿大人在 COVID-19 大流行期间报告心理健康状况下降,人们对自杀率可能上升表示担忧。本研究调查了大流行对成年人自杀意念的潜在影响。
我们通过分析 2020 年 9 月 11 日至 12 月 4 日期间的 COVID-19 和心理健康调查(Survey on COVID-19 and Mental Health)和 2019 年加拿大社区健康调查的数据,比较了 2020 年和 2019 年自我报告的自杀意念。我们采用逻辑回归来确定在大流行期间哪些人群自杀意念的风险更高。
自大流行开始以来报告有自杀意念的成年人比例(2.44%)与 2019 年过去 12 个月报告有自杀意念的比例(2.73%)没有显著差异。我们在众多社会人口群体中也没有发现 2020 年与 2019 年相比,近期自杀意念的流行率存在显著差异。在大流行期间报告有自杀意念的风险因素包括年龄在 65 岁以下、在加拿大出生或从事一线工作;报告与大流行相关的收入/失业或孤独/隔离;经历过一生中高度紧张/创伤性事件;以及家庭收入和教育程度较低。
本研究中一般没有观察到因大流行而导致自杀意念变化的证据。需要继续监测自杀和风险/保护因素,以为自杀预防工作提供信息。
