The main objective of the present study was to determine the association between completed suicides and season of the year in Iran during 2006-2010.
Data on completed suicides were collected by questionnaires field out by the family members of the victims in Legal Medicine Centers throughout the country over the period from 2006 to 2010. The maximum number of completed suicides (380) was observed in August, while the minimum number (231) was reported in February.
Season-wise, completed suicides were most prevalent in summer (1040), whereas least prevalent in winter (726). Mean (SD) age of individuals having committed suicide was 31.5 (14.6) years. This value did not change significantly in different seasons (P=0.051); nor, was a statistically significant difference observed in the educational level and the reason for suicide across different seasons of the year. Self-immolation and toxic poisoning were found to be significantly less common in autumn and winter (P<0.05), respectively. The number of completed suicides was higher in warm seasons.
Season of the year had significant relationships with gender as well the method of suicide, while no significant association was observed for age, level of education, and reason for suicide.
本研究的主要目的是确定2006 - 2010年伊朗自杀死亡与一年中季节之间的关联。
2006年至2010年期间，通过全国各地法医中心受害者家属填写的问卷收集自杀死亡数据。8月观察到的自杀死亡人数最多（380例），而2月报告的自杀死亡人数最少（231例）。
按季节划分，自杀死亡在夏季最为普遍（1040例），而在冬季最为少见（726例）。自杀者的平均（标准差）年龄为31.5（14.6）岁。该数值在不同季节没有显著变化（P = 0.051）；一年中不同季节的教育水平和自杀原因也未观察到统计学上的显著差异。自焚和中毒分别在秋季和冬季明显较少见（P < 0.05）。温暖季节的自杀死亡人数较多。
一年中的季节与性别以及自杀方式有显著关系，而在年龄、教育水平和自杀原因方面未观察到显著关联。
