急性上消化道出血的节律性及与气象的相关性研究

STUDY ON RHYTHM OF ACUTE UPPER GASTROINTESTINAL BLEEDING AND ITS RELATIONSHIP WITH METEOROLOGICAL FACTORS

目的：研究杭州地区上消化道出血（UGIB）发病的节律性及与气象的相关性。方法：收集杭州市第三人民医院2003～2011年UGIB病例及此期间每日气象资料，比较季节、节气间的发病差异，分析气象因素与UGIB发病的关系。结果：UGIB在季节、节气间的发病有显著差异（P〈0．05）；冬春季发病多于夏秋季；惊蛰、清明、谷雨、霜降、立冬、小雪节气高发。相关分析显示UGIB发病与平均大气压呈正相关（r=0．719，P=0．008），与平均人体舒适度指数呈负相关（r=-0．727，P=0．007）。结论：UGIB在寒冷季节及天气变化大的节气发病较多，提示对UGIB的预防重点应放在高发时段。

Objective: To study the rhythm of acute upper gastrointestinal bleeding( UGIB) and its relationship with meteorological factors. Methods: The UGIB cases who were hospitalized in Hangzhou No. 3 People's Hospital from 2003 to 2011,as well as the daily meteor- ological data in this period,were collected. The variation in incidence of UGIB in different seasons and solar terms was evaluated,and the relationship between meteorological factors and incidence of UGIB was analyzed. Results: The incidence of UGIB varied significantly in different seasons( P < 0. 01) and solar terms( P < 0. 01). The incidence of UGIB was significantly higher in winter and spring than in summer and autumn. In addition,the incidence of UGIB was high in the Waking of Insects,Pure Brightness,Grain Rain,Frost's Descent,Beginning of Winter,and Slight Snow. The correlation analysis showed that the incidence of UGIB was positively correlated with average atmospheric pressure and negatively correlated with human comfort index. Conclusion: The incidence of UGIB is high in cold seasons and the solar terms with great changes in the weather,suggesting that UGIB should be prevented mainly in peak periods.
