Suicide is one of the most important public health problems. There was an association between suicide and several factors such as psychiatric diseases and psychological characteristics, somatic illness, cultural, socioeconomic, familial, occupational and individual risk factors. Also, high altitude and climatic factors including high temperature, cloudiness, more sunshine and low rainfalls were defined as some of these risk factors in the literature. In this study, we aimed to investigate correlation between suicide rates and altitudes of all cities in Turkey and between suicide rates and climatic factors including Rainfall Activity Index, Winter Mean Temperatures, Summer Mean Temperatures and Temperature Difference between January and July previously defined by several authors in the broad series in Turkey. In Turkey, 29865 suicidal deaths occurred in 10 years period between 2006 and 2015. Of them, 21020 (70.4%) were males and 8845 (29.6%) were females. In this study, we found that high altitude above 1500 m, winter median temperature lower than -10 °C and hard temperature changes above 25 °C between winter and summer of settlements were important factors that affected on female suicide rates appropriate to knowledge which defined in previous studies. In conclusion, we suggested that the associations among suicide rates with altitudes and climate should be studied in wider series obtained from different countries for reaching more reliable results.
自杀是最重要的公共卫生问题之一。自杀与多种因素相关，如精神疾病和心理特征、躯体疾病、文化、社会经济、家庭、职业及个人风险因素。此外，高海拔以及包括高温、多云、日照多和降雨少在内的气候因素在文献中被确定为这些风险因素的一部分。在本研究中，我们旨在调查土耳其所有城市的自杀率与海拔之间的相关性，以及自杀率与降雨活动指数、冬季平均气温、夏季平均气温和此前土耳其多位作者在广泛系列研究中定义的1月至7月温差等气候因素之间的相关性。在土耳其，2006年至2015年的10年间发生了29865例自杀死亡事件。其中，男性21020例（70.4%），女性8845例（29.6%）。在本研究中，我们发现海拔1500米以上、冬季中位数温度低于-10°C以及居住地冬夏间25°C以上的剧烈温度变化是影响女性自杀率（与先前研究中定义的知识相符）的重要因素。总之，我们建议应从不同国家获取更广泛的系列数据来研究自杀率与海拔和气候之间的关联，以获得更可靠的结果。
