上海某综合性医院急诊2007～2010年蓄意自伤就诊情况与气象因素的关系

Meteorological impact on deliberate self-harm patients visiting emergency room of a general hospital in Shanghai from 2007 to 2010

目的调查上海一家综合性医院急诊近4年蓄意自伤(DSH)就诊者的特征,同时分析气象因素的影响。方法选择2007～2010年就诊的DSH患者,与同期气象资料进行比较,分析气象因素的影响。结果 4年中急诊有1 495例DSH患者就诊,经logistic回归模型采用前进法发现,日最高温度越高、最低湿度越低,DSH发生的可能性越大。夏季DSH高发,至8月达最高峰,冬季较少发,尤其2月最少;傍晚19:00～22:59及11:00～14:59急诊DSH就诊人次最多。温度和湿度的影响无性别差异。结论急诊是DSH研究和干预的重要阵地。春夏季是DSH预防的关键时期。完善急诊伤害登记系统以识别综合性医院急诊DSH是相关研究和预防的前提。

Objective To describe the characteristics of deliberate self-harm （DSH） patients treated in the emergency room （ER） of a general hospital in Shanghai and to identify potential meteorological risk factors for DSH. Methods Logistic regression analysis found that the higher daily maximum temperatue and the lower The characteristics of 1495 patients with DSH treated in ER from 2007 to 2010 were analyzed with the homochronous meteorological factors. Results Logistic regression analysis found that the higher daily maximum temperatue and the lower daily minimum humidity,the higher the possibility of DSH was. The epidemical season of DSH was summer, especially in August. And the slack season was winter, especially in February. Patients with DSH visited E R mainly during 19：00 -23：00 o＇clock and 11：00- 13：00 o＇clock. There was no significant sex difference in the effect of temperature and humidity on DSH. Conclusion ER in general hospital is the main position for the intervention and study on DSH, and the key period for prevention of DSH is in spring and in summer. A perfect ER registration system of DSH is essential to the identification, prevention and related studies of DSH.
