| Outline of Final Research Achievements |
Associations between nuclear disasters and suicide have been examined to a limited extent. The aim is to clarify suicide rates in evacuation areas after the nuclear disaster in Fukushima. This descriptive study used monthly data from vital statistics between March 2009 and December 2015. Suicide rates in the evacuation areas were compared with the national average. Male suicide rates in evacuation areas increased significantly immediately after the disaster, and then began to increase again after 4-year in post-disaster. Female rates declined slightly during the first year and then increased significantly over the subsequent 3-year. Suicide rate in both gender exceeded the rates in non-evacuation areas at 4.5 years post-disaster, and showed an increasing trend thereafter. Our findings suggest the need to keep in mind that, when providing post-disaster mental health services, suicide rates can eventually increase even if they initially decrease.
