Abstract

Purpose: To assess temporal patterns of Veteran suicide deaths from 2001 to 2021.

Methods: Data from Veterans Affairs (VA) and Department of Defense (DoD) administrative sources and the VA/DoD Mortality Data Repository identified 133,867 Veteran suicides from 2001 to 2021. Incidence Rate Ratios (IRRs) and Joinpoint regression assessed patterns of Veteran suicide across seasons, days of the week, and 14 holidays; overall and by sex and age.

Results: Incidence of Veteran suicide was highest in summers and on Mondays. Veteran suicide incidence was lower on six holidays: Martin Luther King Jr. Day (IRR = 0.82, 95% CI = 0.73-0.93), Presidents' Day (IRR = 0.88, 0.78, 0.99), Memorial Day (IRR = 0.89, CI = 0.79-0.99), Labor Day (IRR = 0.88, CI = 0.78-0.98), Thanksgiving (IRR = 0.81, CI = 0.71-0.92), and Christmas (IRR = 0.78, CI = 0.68-0.89). Suicide incidence was elevated on New Year's Day (IRR = 1.17, CI = 1.05-1.31), particularly among Veterans 25-34 years old (IRR = 1.64, CI = 1.19-2.26). An increasing trend in daily average suicides was indicated from December 30th to January 1st (β = 1.79, p < 0.05). Both seasonal and day of the week effects were present in most subpopulations. Holiday effects were most prevalent among men and varied by age.

Conclusions: Veteran suicide incidence was elevated in summer months, on Mondays, and on New Year's Day. Temporal patterns differed by sex and age. Findings can inform ongoing Veteran suicide prevention efforts.

退伍军人自杀的时间模式：季节、星期和节假日的变化。

目的：评估 2001 年至 2021 年退伍军人自杀死亡的时间模式：来自退伍军人事务局（VA）和国防部（DoD）行政来源的数据以及退伍军人事务局/国防部死亡率数据存储库（VA/DoD Mortality Data Repository）的数据确定了 2001 年至 2021 年期间 133,867 例退伍军人自杀事件。发病率比（IRR）和联结点回归评估了退伍军人在不同季节、一周中的不同天数和14个节假日的自杀模式；总体情况以及按性别和年龄分类的情况：退伍军人自杀率在夏季和周一最高。退伍军人在六个节假日的自杀率较低：马丁-路德-金纪念日（IRR = 0.82，95% CI = 0.73-0.93）、总统纪念日（IRR = 0.88、0.78、0.99）、阵亡将士纪念日（IRR = 0.89，CI = 0.79-0.99）、劳动节（IRR = 0.88，CI = 0.78-0.98）、感恩节（IRR = 0.81，CI = 0.71-0.92）和圣诞节（IRR = 0.78，CI = 0.68-0.89）。元旦当天的自杀率较高（IRR = 1.17，CI = 1.05-1.31），尤其是 25-34 岁的退伍军人（IRR = 1.64，CI = 1.19-2.26）。从 12 月 30 日到次年 1 月 1 日，日均自杀人数呈上升趋势（β = 1.79，P 结论）：退伍军人的自杀率在夏季、周一和元旦都有所上升。时间模式因性别和年龄而异。研究结果可为正在进行的退伍军人自杀预防工作提供参考。

期刊介绍： An excellent resource for researchers as well as students, Social Cognition features reports on empirical research, self-perception, self-concept, social neuroscience, person-memory integration, social schemata, the development of social cognition, and the role of affect in memory and perception. Three broad concerns define the scope of the journal: - The processes underlying the perception, memory, and judgment of social stimuli - The effects of social, cultural, and affective factors on the processing of information - The behavioral and interpersonal consequences of cognitive processes.
