Study on effects of social gradient on suicide

社会梯度对自杀的影响包括：(1)失业和自杀的统计分析；(2)社区预防自杀财政资金对县自杀率的影响研究；(3)社区居民社会资本和心理困扰的研究；(4)东日本灾区社区居民的社会纽带和心理困扰的研究。失业人员的自杀率高于就业人员。在采取了密集自杀预防政策的东北北部地区，自杀率有所下降。社会资本水平与社区居民心理困扰显著相关，提示加强社会纽带的重要性。

The effects of social gradient on suicide were investigated as follows: 1) statistical analysis of unemployed people and suicide, 2) study on effects of financial funds of community suicide prevention on prefectural suicide rates, 3) study on social capital and psychological distress of community residents, 4) study on social tie and psychological distress of community residents suffered from Higashi-nihon Disaster. Suicide rate of unemployment people was greater than that of employed people. Decreases in suicide rates were observed in Northern-Tohoku District where intensive suicide prevention policies were employed. The level of social capital was significantly associated with psychological distress in community residents, suggesting the importance of strengthening social tie.
