The aim of this study was to determine whether climate factors correlate with variations in the rate of pediatric intussusception cases presenting to the Children's Hospital in Suzhou, China.
The hospital records of 5,994 pediatric cases of intussusception who had presented between Aug 2006 and Dec 2011 were retrospectively analyzed. Demographic data and air enema reduction data were collected for each case.
The monthly rate of new intussusception cases fluctuated throughout the year generally rising from April to September with a peak from May to July. This annual cycling of intussusception incidence was highly significant over the 5 year observation period. Poisson regression analysis showed that the monthly number of intussusception cases was associated with an increase in mean temperature per month (P = 0.0001), sum of sunshine per month (P<0.0001), precipitation per month (P<0.0001), and was marginally associated with increased mean wind speed per month (P = 0.0709).
The incidence of intussusception in Suzhou was seasonally variable with a peak in cases presenting during hotter, sunnier, and wetter months demonstrating a positive association with certain climatic factors.
本研究旨在确定气候因素是否与中国苏州儿童医院小儿肠套叠病例就诊率的变化相关。
回顾性分析2006年8月至2011年12月期间5994例小儿肠套叠病例的医院记录。收集每例病例的人口统计学数据和气钡灌肠复位数据。
新肠套叠病例的月发病率全年波动，一般从4月到9月上升，5月到7月达到高峰。在5年观察期内，肠套叠发病率的这种年度周期性变化非常显著。泊松回归分析表明，每月肠套叠病例数与每月平均温度升高（P = 0.0001）、每月日照总时数（P<0.0001）、每月降水量（P<0.0001）相关，与每月平均风速增加也有微弱关联（P = 0.0709）。
苏州肠套叠的发病率存在季节性变化，在较热、日照较多和较湿润的月份病例数达到高峰，表明与某些气候因素呈正相关。
