目的探讨雅安市采血量与气象因素之间的关系。方法对雅安市2007～2011年连续5年的采血量与白天降雨量、日照时间、平均气压、平均气温4个气象要素进行回归及相关分析。结果雅安市的采血量与白天降雨量有负相关关系(r=-0.102,p=0.000),与日照时间有正相关关系(r=0.080,p=0.002)。结论气象因素是影响人群献血的一个重要原因,本研究对血站在采血工作中调整工作安排有指导意义。
Objective To explore the relationship between the amount of blood collected and the weather in Ya’an. Methods The regression and correlation analysis of four meteorological factors including blood volume in daytime, daytime sunshine time, mean air pressure and mean air temperature from 2007 to 2011 in Yaan City were conducted. Results There was a negative correlation between blood volume and daytime rainfall (r = -0.102, p = 0.000) in Ya’an City and a positive correlation with sunshine time (r = 0.080, p = 0.002). Conclusion The meteorological factors are one of the important reasons that affect blood donation in the population. This study is instructive in adjusting the work schedule of blood collection in blood collection.
