Suicides have increased in the United States, but trends among sociodemographic and clinical groups have not been characterized. Using nationally representative survey data, Olfson and colleagues found that the percentage of adults making a recent suicide attempt increased from 0.62% in 2004/2005 to 0.79% in 2012/2013. The increase in risk was significantly larger among younger adults and among adults with no more than a high school education. In an Editorial, Caine discusses implications for suicide research.

在美国，自杀人数有所增加，但是社会人口学和临床人群之间的趋势尚未得到表征。使用全国代表性的调查数据，Olfson及其同事发现，最近一次自杀未遂的成年人比例从2004/2005年的0.62％增加到2012/2013年的0.79％。年轻人和受过高等教育的成年人中，风险的增加明显更大。凯恩（Caine）在社论中讨论了自杀研究的意义。
