Insights
Higher temperatures and increased air visibility correlate with more frequent pediatric epistaxis (nosebleeds). Humidity showed no significant link. This study analyzed 6805 cases to understand environmental impacts on children's nosebleeds.
Area of Science:
- Environmental Health
- Pediatric Medicine
- Epidemiology
Background:
- Epistaxis, or nosebleeds, is common in children.
- Environmental factors are suspected to influence epistaxis frequency.
- Understanding these correlations can aid in prevention and management.
Purpose of the Study:
- To investigate the relationship between meteorological variables and pediatric epistaxis incidence.
- To identify specific weather patterns associated with increased nosebleed occurrences in children.
Main Methods:
- Retrospective analysis of 6805 pediatric epistaxis cases from 2016-2017.
- Correlation analysis between monthly epistaxis cases and meteorological factors (temperature, humidity, air visibility).
- Development of a Poisson regression model for prediction.
Main Results:
- A strong positive correlation was observed between ambient temperature and pediatric epistaxis (r=0.801, p<0.001).
- A very strong positive correlation was found between high air visibility and epistaxis (r=0.909, p<0.001).
- Humidity showed a weak, non-significant negative correlation (r=-0.225, p=0.29).
Conclusions:
- Pediatric epistaxis frequency is positively correlated with both temperature and air visibility.
- Humidity does not appear to be a significant factor in pediatric epistaxis rates.
- The findings challenge previous assumptions about temperature's inverse relationship with epistaxis.
Objective:
To investigate the correlations between multiple meteorological variables and the frequency of epistaxis in the pediatric population.
Methods:
Children diagnosed with epistaxis in 2016 and 2017 were selected from the Outpatient Department of the Children's Hospital of Zhejiang University School of Medicine. The correlations between multiple meteorological factors and the incidence of pediatric epistaxis each month, were analyzed. A Poisson regression model was generated to predict the cases of pediatric epistaxis using both the 2-year study data and the 4-month new data.
Results:
There were 6805 cases of pediatric epistaxis (mean age 4.99 years). Contrary to previously reported inverse associations between ambient temperature and presentation rates for patients with epistaxis, a significant strong positive correlation was found between temperature and pediatric epistaxis rates (Pearson's r = 0.801 p < 0.001). A weak negative correlation between humidity and pediatric epistaxis was found, but it was not significant (Pearson's r = -0.225 p = 0.29). A very strong positive correlation between high air visibility and pediatric epistaxis was identified (Pearson's r = 0.909 p < 0.001). The predictions from the Poisson regression model have a mean error rate of 5.70% ± 22.71%.
Conclusion:
A positive correlation between the frequency of pediatric epistaxis existed for both temperature and air visibility. No significant correlation was found for humidity.
