Abstract


Objective
This study was conducted to investigate the association between meteorological factors and the number of patients who visited an emergency department after suicide attempts daily.
Methods
We conducted a retrospective analysis study of 359 patients who visited an emergency department after suicide attempts from January 1, 2016, to December 31, 2016. We used the Poisson regression model to analyze the association.
Results
Three hundred and fifty-nine patients were enrolled in this study. According to the Poisson regression analysis, the average temperature on the day of visit (adjusted odds ratio [aOR], 1.038; 95% confidence interval [CI], 1.018-1.058), relative humidity (aOR, 0.987; 95% CI, 0.976-0.997), and solar radiation (aOR, 0.965; 95% CI, 0.939-0.993) were meteorological factors associated with the daily number of patients in the non-violent suicidal attempt group.
Conclusion
This study showed that meteorological factors are associated with the number of patients who visited an emergency department after suicide attempts daily.
