目的探讨随州市气象因素与发热伴血小板减少综合征(SFTS)发病之间的关系。方法收集2010-2013年随州市每月SFTS发病资料和气象资料(月平均气温、气压、降水量、日照小时数),使用SPSS17.0对SFTS和气象因素资料进行相关和回归分析。结果 SFTS发病与月平均气温、月降水量和日照小时数呈正相关(P<0.01),与月平均气压呈负相关(P<0.01)。逐步回归法筛选出回归方程为:Y(月发病数)=688.81-0.68X2(月平均气压),决定系数R2=0.708。结论气象因素对发热伴血小板减少综合征发病有重要影响。
Objective To investigate the relationship between meteorological factors and the incidence of fever with thrombocytopenia syndrome (SFTS) in Suizhou. Methods The monthly incidence of SFTS and meteorological data (monthly average temperature, barometric pressure, precipitation and sunshine hours) in Suizhou from 2010 to 2013 were collected. Correlation and regression analysis of SFTS and meteorological factors were carried out using SPSS17.0. Results The incidence of SFTS was positively correlated with monthly average temperature, monthly precipitation and sunshine hours (P <0.01), and negatively correlated with monthly mean air pressure (P <0.01). The regression equation was screened by stepwise regression: Y (monthly incidence) = 688.81-0.68X2 (monthly mean pressure), the coefficient of determination R2 = 0.708. Conclusion Meteorological factors have an important impact on the incidence of fever with thrombocytopenia syndrome.
