Allergy:中国北方草原高度花粉接触情况下的花粉诱导的过敏性鼻炎流行度分析

2018-01-22 AlexYang MedSci原创

最近,有研究人员调查了流行病学和医生诊断的花粉诱导的AR(PiAR)在中国北部草原中的流行度情况,并且研究了密度和花粉接触时间对PiAR流行度的影响。研究总共包括了6043名受试者,并且完成了研究,其中32.4%的受试者为流行病学AR,18.5%的受试者为PiAR。流行度在男性中要比女性更高(19.6% vs 17.4%, P=0.024),但是在2个主要居住和种族之间没有差异(汉族和蒙古族)。来

最近,有研究人员调查了流行病学和医生诊断的花粉诱导的AR(PiAR)在中国北部草原中的流行度情况,并且研究了密度和花粉接触时间对PiAR流行度的影响。

研究总共包括了6043名受试者,并且完成了研究,其中32.4%的受试者为流行病学AR,18.5%的受试者为PiAR。流行度在男性中要比女性更高(19.6% vs 17.4%, P=0.024),但是在2个主要居住和种族之间没有差异(汉族和蒙古族)。来自城市的受试者比来自乡村的受试者表现出了PiAR更高的流行度(23.1% vs 14.0%, P<0.001)。大多数的PiAR病人对2中或者更多的花粉敏感(79.4%),主要包括了蒿属、藜属和葎草,并且这三种是通过SPT检测出的最流行的3中花粉过敏原。另外,在调查的6个区域中,流行病学AR(从18.6%到52.9%)和PiAR(从10.5%到31.4%)的流行度存在显著的区域差异。PiAR症状与花粉数目、温度和降水呈现正相关关系(P<0.05),但是与风速和压力负相关(P<0.05)。

最后,研究人员指出,PiAR在调查的区域中的由于高度的季节花粉接触,流行度是非常高的,并且还会受到局部环境和气候条件的影响。
