The problem of time distribution of suicide has aroused the interest of various investigators in the past. A population-based study on the association of the birthday in relation to the time of suicide taking into account sex and the chosen suicide method was conducted.
The study included all residents of Bavaria who died between 1998 and 2003 and whose death was classified as suicide by the death certificate. In sum, 11378 deaths from suicide were included. The suicide ratios in various time frames around the individuals' birthdays were compared with expected suicide ratios.
The occurrence of suicide did not vary around the birthday. Different time frames (3, 7, 14, 30, and 90 days) before as well as after the individuals' birthdays were taken into account. Even after dichotomization regarding the chosen method as well as sex differences, no significant association between birthdays and dates of suicide could be found.
There is no evidence for a "birthday blues" effect on suicide.
自杀时间分布问题在过去引起了众多研究者的兴趣。开展了一项基于人群的研究，探讨生日与自杀时间之间的关联，并考虑了性别和所选自杀方式。
该研究纳入了1998年至2003年间在巴伐利亚死亡且死亡证明将其死亡归类为自杀的所有居民。总计纳入了11378例自杀死亡病例。将个体生日前后不同时间段内的自杀率与预期自杀率进行比较。
生日前后自杀发生率并无差异。考虑了个体生日前以及后的不同时间段（3天、7天、14天、30天和90天）。即使在根据所选方式以及性别差异进行二分法分析后，也未发现生日与自杀日期之间存在显著关联。
没有证据表明存在“生日忧郁症”对自杀的影响。
