Adverse childhood experiences, economic challenges and suicide risk under COVID-19 pandemic: results from U-CORONA study

Abstract

Purpose

The purpose of this study is to examine the synergistic effect of adverse childhood experiences (ACEs) and economic challenges on suicide risk, under the coronavirus disease 2019 (COVID-19) pandemic, using a prospective population-based cohort study.

Design/methodology/approach

Participants included 435 adults (aged from 18 to 92 years, mean = 53.8) from the Utsunomiya COVID-19 seROprevalence Neighborhood Association (U-CORONA) study, a population-based longitudinal study in Utsunomiya city, Japan. The baseline survey was conducted in June 2020, between the first and the second wave of the COVID-19 pandemic in Japan. ACEs were assessed using 13 items, and economic challenges due to the COVID-19 were assessed using one item. In the follow-up study, conducted in October 2020 between the second and the third wave of the COVID-19 pandemic in Japan, suicide risk was assessed using six items from the Mini-International Neuropsychiatric Interview via a self-reported questionnaire.

Findings

This study found positive independent association between ACEs and economic challenges due to COVID-19 and suicide risk. Synergistic effects were also found: the participants with one ACE and economic challenges and those with 2+ ACEs and economic challenges were more likely to be at higher risk of suicide compared to those without ACEs and economic challenges.

Originality/value

The findings suggest that adults with a higher number of ACEs, in addition to severe economic challenges, were more likely to be at risk for suicide during the COVID-19 pandemic.
