Proposal of suicide prevention strategy and implementation of an epidemiological study based on case reports of all suicides in Okayama prefecture

通过对冈山县所有自杀案例的分析，我们发现，窒息自杀(柔术自杀)往往发生在30多岁至40多岁的男性中的某个季节。通过从卫生、劳工和福利部汇编的《生命统计》中建立一个数据集，我们设法确定易受经济收缩影响的人口，以便在他们中间实施预防性干预措施，以减少自杀。此外，通过分析先进地区(秋田县、岩手县和高知区)的自杀预防策略，我们还论证了在城市地区实施其健康促进方法的意义。

By analyzing all the suicide cases in Okayama prefecture, we showed that suffocation suicides(rentan jisatsu) tend to occur during a certain season among men in their 30s to 40s. By creating a data set from the Vital Statistics, which has been compiled by the Ministry of Health, Labour and Welfare, we sought to identify vulnerable population to economic contraction in order to implement preventive interventions among them to reduce suicide. In addition, by analyzing suicide prevention strategies in advanced regions(e. g., Akita prefecture, Iwate prefecture, and Adachi-ku), we also demonstrated a significance of implementing their health promotion approaches in urban areas.
