A decrease in suicide rates in Japanese rural towns after community-based intervention by the health promotion approach.

A community-based intervention study for suicide prevention was conducted in six towns (total population 43,964) in Akita Prefecture of Japan according to a quasi-experimental design to reduce suicide rates in rural towns. Public awareness raising activities using a health promotion approach emphasizing the empowerment of residents and civic participation were conducted. The welfare measures of promoting a sense of purpose among senior citizens and creating a community network were also taken. As a result, the suicide rate per 100,000 in the intervention towns decreased from 70.8 before intervention (1999) to 34.1 after intervention (2004). The suicide rate per 100,000 in the control towns was 47.8 before intervention and 49.1 after intervention.
