Suicide patterns and characteristics in Akita, Japan.

Akita Prefecture currently has the highest rate of suicide in Japan. Given this alarming statistic, investigation of the underlying causes of suicide and identification of strategies for suicide prevention are imperative. Members of the Akita Prefectural Medical Association (APMA) see most of the individuals who commit suicides in Akita Prefecture, so data from the APMA would prove advantageous in any investigation of suicides. In this study, members of the APMA who had attended to individuals who had committed suicide were asked to complete a questionnaire about the case to determine the factors underlying suicide in Akita Prefecture. From 1 July 2001 to 30 June 2002, a total of 138 cases (102 males, 36 females) of suicide were reported. Most suicide cases were of 50-69 year olds. Many cases involved relatively lethal methods (such as hanging). Most suicides were performed at home and at a time when the rest of the family was asleep or absent. The most common complaint appeared to be economic-related problems. Depressive disorder was the most common psychiatric disorder, and many cases displayed high depressive trait scores. The present results do not exclude the possibility that economic-related problems are playing a major role in recent increases in suicide numbers. However, strategies for dealing with depression as well as economic-related problems are considered important.
