苏州地区气候因素对儿童特应性皮炎就诊量的影响

目的:评估苏州地区气候因素对儿童特应性皮炎(AD)患者就诊数量的影响。方法:收集2019年1～12月苏州大学附属儿童医院皮肤科确诊AD患者资料及同时期苏州地区气候数据，包括气温、相对湿度、风速、降水量。采用统计学软件SPSS 22.0分析，Spearman秩相关分析探索气温、相对湿度、风速、降水量与AD患者就诊例数的相关性。结果:15395例儿童AD患者中男童54.3%,女童45.7%,1～2岁儿童就诊例数最多，就诊高峰在当年3～4月。同时期苏州地区的日平均气温，日平均相对湿度，日平均风速，日平均降水量分别为18.01℃,73.34%,9.16 m/s, 2.48 mm。AD就诊例数与相对湿度显著相关，其相关系数为-0.825,差异有统计学意义(P<0.01),与气温、风速、降水量的相关系数分别为0.084,0.231,-0.245,均无统计学意义(P>0.05)。结论:AD就诊例数与空气相对湿度呈显著负相关，与气温、风速及降水量无明显相关。

Effects of climatic factors on the outpatient visits of children's atopic dermatitis in Suzhou

Objective: To evaluate the influence of climatic factors on the number of visits of children with atopic dermatitis (AD) in Suzhou. Methods: The data of AD patients diagnosed in the department of dermatology, children's Hospital of Soochow University from January 2019 to December 2019, and the climatic data in Suzhou during the same period were collected, including temperature, relative humidity, wind speed, and precipitation. Statistical software Statistical Product and Service Solutions (SPSS) analysis and Spearman correlation analysis were employed to study the relationship between climatic factors including temperature, relative humidity, wind speed, precipitation and the number of AD visits. Results: 15395 children patients, 54.3% were boys and 45.7% were girls. One to two years old children account for the most cases of patients and the visit peaks occurred in March to April of that year. The daily mean level of temperature, relative humidity, wind speed, precipitation were 18.01℃, 73.34%, 9.16 m/s and 2.48 mm. Correlation analysis showed that the number of AD visits were positively correlated with relative humidity and the effect coefficient was -0.825, which was statistically significant (P＜0.01). The correlation coefficients between the number of AD visits and air temperature, wind speed, and precipitation were 0.084, 0.231, and -0.245, respectively, all of which were not statistically significant (P>0.05). Conclusion: The number of AD visits has significant negative correlation with relative humidity, but has no significant correlation with temperature, wind speed and precipitation.
