摘要
目的探讨脑血管病发病与气象因素间的关系.方法收集青岛市1998～2002年6186例脑血管病患者[脑出血(CH)1179例、脑梗死(CI)4821例、蛛网膜下腔出血(SAH)186例]的发病时间及同期的月平均气温、气压、相对湿度、风速等气象资料.圆分布分析脑血管病发病的季节规律;直线相关、多元逐步回归分析气象因素与脑血管病发病之间的关系.结果 CH冬季高发,平均角在1月份(P<0.05);CI及SAH均于秋季高发,平均角在10月份(均P<0.05).CH多发于低气温、高气压的气象条件(r= -0.370、0.349, 均P<0.05),CI多发于高温、高气压、低湿度的气象条件(r=0.308、0.264、-0.370,均P<0.05).影响月发病人数的气象因素,CH是月平均气压、相对湿度和风速,CI是月平均气压和气温.结论气象因素是脑血管病发病的影响因素,在脑血管病的预防工作中应充分考虑其发病的季节特点.气象因素为自变量的多元逐步回归方程不宜用来进行预测发病人数.
Objective To study the relationship between cerebral vascular disease （CVD） and meteorological factors. Methods From 1998 to 2002, 6186 patients with CVD in Qingdao urban were studied. There were 1179 cases of intracerebral hemorrhage （CH）, 4821cases of cerebral infarction （CI） and 186 cases of subarachnoid hemorrage （SAH）. The relationship between the onset of CVD and meteorological factors including temperature, air pressure, relative humidity, wind velocity was analyzed by circular distribution analysis, Pearson correlation and multiple stepwise regression. Results High incidence of CH was found in winter and the mean angle was in January （P 〈 0. 05 ）, however CI and SAH had mean angles in October （all P 〈 0. 05 ）. Pearson correlation analysis suggested that higher incidence of CH was related with lower temperature and higher barometric pressure situation （r = - 0. 370, 0. 349, all P 〈 0. 05 ） , and higher incidence of CI was related with higher temperature, higher barometric.pressure and lower relative humidity situation （ r = 0. 308, 0. 264, - 0. 370, all P 〈 0. 05 ）. Multiple stepwise regression found that the meteorological factors which influenced the incidence of CH per month were monthly average barometric pressure, relatively humidity and wind speed, and the incidence of CI was affected by monthly average barometric pressure and temperature. Conclusions The incidence of CVD presents seasonal rhythm in Qingdao urban and it is influenced by meteorological factors. Enough consideration of meteorological factors should be paid on preventive works for stroke. But meteorological factors may not be regarded as anticipating indexes of the incidence of CVD.
