To determine the factors underlying suicide in Akita prefecture, a questionnaire survey was conducted among members of the Akita Prefectural Medical Association (APMA), regarding suicide cases they attended. During the investigation period (1 July 2001-30 June 2002), the total number of suicide cases was 243 (138 completed, 105 attempted). Significant differences were identified between completed and attempted suicide groups in terms of gender, age distribution, and suicidal methods. Specifically, in the completed suicide group, the number of male completers exceeded that of female completers, the number of middle-aged or elderly completers was high, and the majority of completed suicide cases involved hanging as the suicide method. Conversely, in the attempted suicide group, the number of female attempters exceeded that of male attempters, younger attempters were frequent, hanging was rare, and drug overdose or cutting was common. In addition, the number of cases involving a history of previous suicide attempts was significantly higher in the attempted suicide group than in the completed suicide group. The results of the present study support the concept that the completed and attempted suicide groups are essentially of a different nature. Furthermore, the number of cases involving a history of previous suicide attempts was found to be significantly lower in the completed suicide group than in the attempted suicide group. This result indicates the difficulty in decreasing the number of completed suicides by simply providing intervention and care for individuals who have attempted suicide.
为确定秋田县自杀背后的因素，对秋田县医学协会（APMA）成员就他们所处理的自杀案例进行了问卷调查。在调查期间（2001年7月1日至2002年6月30日），自杀案例总数为243例（138例自杀死亡，105例自杀未遂）。在性别、年龄分布和自杀方式方面，自杀死亡组和自杀未遂组之间存在显著差异。具体而言，在自杀死亡组中，男性自杀死亡者的数量超过女性自杀死亡者，中年或老年自杀死亡者数量较多，且大多数自杀死亡案例的自杀方式为上吊。相反，在自杀未遂组中，女性自杀未遂者的数量超过男性自杀未遂者，年轻自杀未遂者较为常见，上吊很少见，药物过量或割伤很常见。此外，有过自杀未遂史的案例数量在自杀未遂组中显著高于自杀死亡组。本研究结果支持这样一种观念，即自杀死亡组和自杀未遂组本质上具有不同的性质。此外，发现有过自杀未遂史的案例数量在自杀死亡组中显著低于自杀未遂组。这一结果表明，仅仅为有自杀未遂经历的个体提供干预和护理，难以降低自杀死亡的数量。
