[Study on the correlation between meteorological factors and allergic rhinitis in outpatients in Yangzhou].

Objective:To investigate the characteristics of allergic rhinitis in Yangzhou area and its correlation with meteorological factors. Method:The characteristics of 17 491 cases of AR were analyzed in Yangzhou from 2015 to 2017. Meteorological environmental parameters, including mean temperature, air pressure, wind speed, humidity and AQI index, were monitored at the same period. The relationship between the onset characteristics of AR patients and meteorological factors was also analyzed. Result:The number of patients with allergic rhinitis in 2015, 2016 and 2017 were 6 167, 5 620 and 5 704. The total difference of the number of patients in 3 years was not statistically significant (P＞0.05). Each year the number of patients reached the peak in October, April, the lowest in February, and less than the other seasons in the summer (P<0.05). The number of visits per year reached peak in October, the lowest in February, and significantly less in summer than in other seasons (P<0.05). The number of children under the age of 12 is relatively small, and the number of patients aged 20 to 40 is the largest. In different age groups, the number of male patients was higher than that of women. There was a positive correlation between the average temperature and AQI index of the average allergic rhinitis patients(r=0.635, P=0.027; r=0.587, P=0.045), and the average temperature and average humidity of the patients with average allergic rhinitis were negatively correlated with regional average humidity and average wind speed(r=-0.193, P=0.045; r=-0.862, P=0.000). Conclusion:The incidence of allergic rhinitis in Yangzhou area has obvious age regularity and seasonality, and there may be some correlation between meteorological factors(especially AQI index) and the incidence of allergic rhinitis in patients.目的：探讨扬州地区变应性鼻炎（AR）患者的发病特点及其与气象因素的相关性。方法：分析2015-2017年扬州地区17 491例AR患者的发病特征，同期监测该地区气象环境参数，包括平均气温、平均气压、平均风速、平均湿度、平均空气质量指数（AQI），并分析AR患者发病特点与气象因素之间的关系。结果：2015、2016及2017年AR患者就诊例数分别为6 167、5 620、5 704例，3年总体比较差异无统计学意义（P＞0.05）；3年中每年患者就诊数量均在10月份达到高峰，4月份次之，2月份就诊量最少，夏季明显少于其他季节（P<0.05）。≤12岁儿童就诊数量较少，＞18~50岁患者就诊数量最多，之后随着年龄增大就诊数量逐渐减少。在不同年龄段，男性患者就诊量均高于女性。平均AR患者就诊例数与平均温度、AQI呈正相关（r=0.635，P=0.027；r=0.587，P=0.045）；平均AR患者就诊例数与地区平均湿度、平均风速呈负相关（r=-0.193，P=0.045；r=-0.862，P=0.000）。结论：扬州地区AR患者发病有明显年龄规律及季节性，气象因素（尤其是AQI指数）同患者AR发病率之间可能存在一定的相关性。.
