Cumulative incidence of suicidal ideation and associated factors among adults living in temporary housing during the three years after the Great East Japan Earthquake

摘要

Background: The effect of disasters on suicidality is not known. We aimed to retrospectively determine the cumulative incidence of suicidal ideation during the 3 years after the Great East Japan Earthquake among residents in temporary housing without prior suicidal ideation, as compared to the general population. Moreover, we aimed to identify the risk factors for the onset of suicidal ideation.
