Methods: the patients with epistaxis in emergency department and outpatient department of a hospital in Shenyang from 2018 to 2020 were selected as the research objects. Pearson correlation and linear regression were used to statistically analyze the relationship between nosebleeds and meteorological conditions, and the influencing factors of nosebleeds were determined. Results: in 2018, air humidity and air temperature were negatively correlated with nosebleeds (P<0.05), while PM2.5, PM10 and CO were positively correlated with nosebleeds (P < 0.05);In 2019, there was a negative correlation between dampness and nosebleeds (P<0.05), while AQI and PM10 were positively correlated with nosebleeds (P < 0.05);In 2020, AQI was negatively correlated with epistaxis (P<0.05). Linear regression analysis was performed on the data with statistically significant correlation analysis results. Results: in 2018, PM2.5 concentration was the influencing factor of nosebleeds (P < 0.05);In 2019, PM10 concentration was the influencing factor of nosebleeds (P < 0.05);In 2020, AQI was the influencing factor of nosebleeds (P<0.05). Conclusion: PM2.5 concentration, PM10 concentration and AQI may be the influencing factors of epistaxis, but further research is needed to determine the exact influencing factors of epistaxis.展开更多
