气象因素对高血压性脑出血发病的影响

背景临床工作中发现脑出血与气象、气候关系较密切.目的探讨气象对高血压性脑出血的影响,为脑出血的预防提供理论依据和预防措施.设计以诊断为依据的横断面研究.地点、对象和方法收集1998-01/2000-12海军杭州疗养院和浙江大学医学院附属二院62例高血压性脑出血患者发病时间与同期杭州地区气象因素的关系进行调查并作比较分析.主要观察指标杭州地区1998/2000各月平均气温、气压及相对湿度的分析及其与脑出血发病的关系.结果在全年气温低、气压高的1,2,12月份高血压性脑出血发病率最高(37/62),气温高、气压低的7,8,9月份发病率最低(6/62),差异有显著性意义(P＜0.001).而气湿高的1,3,6月脑出血发病率(17/62)与气湿低的2,4,5月(18/62)比较,差异无明显意义(P＞0.05).结论气象因素与高血压脑出血有关,低气温、高气压可能是诱发高血压性脑出血的原因之一.

Effects of weatherfactors on the morbidity of hypertensive cerebral hemorrhage

BACKGROUND: A comparatively close relationship of cerebral hemorrhage to weather and climate is found in clinic research.OBJECTIVE: To discuss the effects of weather on hypertensive cerebral hemorrhage for providing a theoretical gist and interventions in cerebral hemorrhage protections.DESIGN: A cross-sectional research on the basis of diagnosis.SETTINGS, PARTICIPANTS AND INTERVENTIONS: Sixty-two cases of hypertensive cerebral hemorrhage were collected from Naval Hangzhou Sanatoriums and the Second Affiliated Hospital of Zhejiang University from January 1998 to December 2000. The regional weather factors of the same time period were investigated. And the relationship between morbidity and weather was analyzed.MAIN OUTCOME MEASURES: Average temperature, air pressure and relative humidity of each month from 1998 to 2000 in Hangzhou region and the relationship between these factors and the morbidity of cerebral hemorrhage were analyzed.RESULTS: The morbidity of hypertensive cerebral was highest(37/62) in the months with the lowest temperature and highest air pressure within the whole year, i. e. January, February and December, whereas, the lowest morbidity(6/62) was in the months with the highest temperature and lowest air pressure, i. e. July, August and September, which had significant difference ( P ＜ 0. 001 ) . However, there was no significance between the morbidity (17/62) in January, March and June with higher humidity and the morbidity (18/62 cases) in February, April and May with lower humidity( P ＞ 0.05).CONCLUSION: There is a relationship between weather and hypertensive cerebral hemorrhage. Low temperature and high air pressure might be one of the inducements to hypertensive cerebral hemorrhage.Wang HL, Xu YL, Hu SG.

Low temperature and high air pressure may be one of the inducements to hypertensive cerebral hemorrhage.
