Association of air temperature with pediatric intussusception in northeastern China: A 10-year retrospective study

The aim of this study was to determine whether an association existed between intussusception and air temperature. A retrospective study was performed between March 2006 and February 2016 to determine the relationship between pediatric primary intussusception (PPI) and air temperature. Information from hospital records of 5922 cases of PPI and Mean daily temperatures of Shenyang were obtained. Pearson correlation analysis was used to examine the association between monthly PPI cases and monthly mean temperature. Factorial analysis-of-variance was used to examine differences in the numbers of seasonal PPI cases during different seasons. Monthly PPI cases fluctuated throughout the year, with a peak in June, and a trough in February. Pearson correlation analysis showed that monthly PPI cases was associated with the monthly mean temperature (p
