Relationship Between Environmental Meteorological Factors and the Incidence of Epistaxis in Different Age Groups in Yangzhou

<b>Objective:</b> To investigate the relationship between environmental and meteorological factors and the incidence of epistaxis in different age groups in Yangzhou, as well as to provide a reference and theoretical basis for epistaxis prevention and treatment. <b>Methods:</b> The patients with epistaxis who were treated in Northern Jiangsu People's Hospital of Jiangsu Province from January 2016 to December 2020 were reviewed, and the relationship between the local environmental meteorological factors at the time of onset and the incidence of epistaxis in different age groups was analyzed, and the potential environmental meteorological risk factors of epistaxis in each age group were determined by Stepwise logistic regression. <b>Results:</b> From 2016 to 2020, there were 24,407 cases of epistaxis, mostly males and children. The effects of O₃ concentration, average humidity, average temperature, NO₂ concentration, sunshine duration, average wind speed, CO concentration, and temperature difference on the study population were statistically significant (<i>P</i> < .05). Analysis by age group showed that there were differences in environmental and meteorological factors related to epistaxis in different age groups. <b>Conclusions:</b> In Yangzhou, epistaxis is more prevalent among males and children. The environmental meteorological factors are related to the incidence of epistaxis in Yangzhou, among which the average humidity and temperature difference are negatively correlated with the incidence of epistaxis. In contrast O₃ concentration, average temperature, NO₂ concentration, sunshine duration, average wind speed, and CO concentration are positively correlated with epistaxis occurrence. However, the impact of these environmental and meteorological factors varies in different age groups.
