Abstract：
Environmental factors are closely associated with pediatric epistaxis. Whether this association differs according to age has not been previously reported. Therefore, we tried to evaluate the differences in associations between environmental factors and epistaxis in children of different ages.
A total of 20,234 patients with epistaxis who visited the hospital between January 1, 2002, and December 31, 2015, were enrolled in this study. The patients were divided into two groups according to their ages: preschool-aged (<6 years) and school-aged children (6-18 years). Daily, monthly, and yearly data on environmental factors were collected. We performed a stepwise logistic regression to identify the potential environmental risk factors for epistaxis in each age group.
The mean number of epistaxis cases per month in both groups was highest in September. The cases were lowest in February in preschool-aged children and in November in school-aged children. Temperature, humidity, maximum wind speed, and sunshine duration were associated with epistaxis in preschool-aged children. Average wind speed, particulate matter (>10 μm diameter), temperature, humidity, sunshine duration, and sulfur dioxide concentration were associated with epistaxis in school-aged children.
This study indicates that the differences in environmental risk factors for epistaxis are associated with the patient\'s age.

摘要：
■环境因素与小儿鼻出血密切相关。以前没有报道过这种关联是否因年龄而异。因此,我们试图评估不同年龄儿童的环境因素与鼻出血之间的关联差异。
■在2002年1月1日至2015年12月31日期间就诊的20,234例鼻出血患者被纳入本研究。根据年龄将患者分为两组：学龄前儿童（<6岁）和学龄儿童（6-18岁）。每日,每月,并收集了有关环境因素的年度数据。我们进行了逐步逻辑回归，以确定每个年龄组鼻出血的潜在环境危险因素。
■两组患者每月平均鼻出血病例数在9月份最高。2月份学龄前儿童的病例最低，11月份学龄儿童的病例最低。温度,湿度,湿度最大风速,学龄前儿童的日照时间与鼻出血有关。平均风速,颗粒物（直径>10μm），温度,湿度,湿度日照时间,和二氧化硫浓度与学龄儿童鼻出血有关。
■这项研究表明，鼻出血的环境危险因素的差异与患者的年龄有关。
