Recent studies have reported changes in the time patterns of suicide, with reduced seasonality in some European and Asian countries. Anyway conflicting data were reported on the fading of suicide seasonality, and in some countries a rising trend was reported.
Harmonic spectral analysis was used to analyze all suicides in Slovenia in the years 1971 to 2002 (14,325 among males; 4350 among females). Analyses of overall changes are based on data aggregated by intervals of 8 years.
In both sexes, seasonal variance accounts for a statistically significant proportion of total variance (36.0% among males; 13.3% among females). Anyway in both sexes the season-attributable variance in the latest interval is considerably lower than in the preceding periods.
Data could not be analyzed according to age or to mental disorder diagnosis, since this information was not available.
The seasonal effect on mortality by suicide is sensitive to change, but its causes seem not to be sex-dependant.
最近的研究报告了自杀时间模式的变化，一些欧洲和亚洲国家的季节性有所降低。然而，关于自杀季节性消退的数据存在冲突，在一些国家还报告了上升趋势。
采用谐波频谱分析方法对1971年至2002年斯洛文尼亚的所有自杀案例进行分析（男性14325例；女性4350例）。总体变化分析基于以8年为间隔汇总的数据。
在男性和女性中，季节性方差在总方差中所占比例均具有统计学意义（男性为36.0%；女性为13.3%）。然而，在男性和女性中，最近一个间隔期内可归因于季节的方差均远低于前几个时期。
由于无法获取相关信息，因此无法按年龄或精神障碍诊断对数据进行分析。
自杀死亡率的季节性效应易发生变化，但其原因似乎并非性别依赖性的。
