We investigated suicide timing over different time periods by age, sex and race/ethnicity. A total of 122,107 suicide deaths were identified from the population-based U.S. National Violent Death Reporting System in 18 U.S. states from 2003 through 2014. Suicides significantly increased (p < .05) from March to peak in September before falling, the first week of the month, and early in the week. Suicides also significantly increased (p < .05) in the morning, mainly peaking during the afternoon, although suicides in adolescents peaked in the evening and in those 65-years and older peaked in the morning. Comprehensive prevention efforts should focus on those at overall increased suicide risk and at peaks of high suicide frequency, especially among those vulnerable subgroups.
我们研究了不同年龄、性别和种族/族裔群体在不同时间段的自杀时间。在 2003 年至 2014 年期间，从美国 18 个州的基于人群的美国国家暴力死亡报告系统中确定了总共 122107 例自杀死亡。自杀事件显著增加（p <.05），从 3 月到 9 月达到峰值，然后下降，在月初和月初的一周。自杀事件也显著增加（p <.05）在早上，主要在下午达到高峰，尽管青少年的自杀事件在晚上达到高峰，而 65 岁及以上的自杀事件在早上达到高峰。综合预防工作应重点关注整体自杀风险增加和自杀频率较高的人群，特别是那些弱势群体。
