【摘要】：目的:研究重庆地区小儿急性肠套叠发病的时间特征及其与气象因素的相关性。方法:对重庆医科大学附属儿童医院收治的急性肠套叠患儿进行大数据病例基础的回顾性分析,并按患儿年龄进行年龄段分组,结合重庆地区同期的气温、气压、湿度、风速、日照时数、降水量等气象资料,运用相关分析和逐步回归方法探讨肠套叠发病与各气象因素的关系。结果:1.重庆地区小儿急性肠套叠总体及婴、幼儿期儿童以春夏季发病为主(P=0.000,P=0.000,P=0.000),学龄前期儿童的发病高峰季节是春冬季(P=0.000),学龄期儿童的发病数量没有显著的季节差异(P=0.607)。2.总体上小儿急性肠套叠月发病数量与月平均温度、月平均风速、月日照总时数、月总降水量正相关(r=0.405,P=0.000;r=0.214,P=0.036;r=0.336,P=0.001;r=0.312,P=0.002),与月平均气压、月平均相对湿度负相关(r=-0.490,P=0.000;r=-0.377,P=0.000),仅月平均气压对进入回归模型(R2=0.240,P=0.000)。3.在婴儿期儿童中,小儿急性肠套叠月发病数量与月平均温度、月平均风速、月日照总时数、月总降水量正相关(r=0.745,P=0.000;r=0.464,P=0.000;r=0.570,P=0.000;r=0.466,P=0.000),与月平均气压、月平均相对湿度负相关(r=-0.784,P=0.000;r=-0.396,P=0.000),月平均气压对进入回归模型(R2=0.614,P=0.000)。4.在幼儿期儿童中,小儿急性肠套叠月发病数量与月平均相对湿度负相关(r=-0.226,P=0.027),月平均相对湿度、月平均风速、月总降水量进入回归模型(R2=0.164,P=0.001)。5.在学龄前儿童中,小儿急性肠套叠月发病数量与月平均风速呈负相关(r=-0.213,P=0.037),月平均相对湿度、月平均风速进入回归模型(R2=0.224,P=0.000)。6.在学龄期儿童中,小儿急性肠套叠月发病数量与六种气象因素都没有显著的相关性,无气象因子进入回归模型。结论:重庆地区小儿急性肠套叠发病情况具有一定的时间周期性,发病情况与气象因素间普遍存在相关性,但不同年龄段儿童其肠套叠发病时间周期性及与气象因素的相关性存在差异。
[Abstract]:Objective: to study the temporal characteristics of acute intussusception in children in Chongqing and its correlation with meteorological factors. Methods: a retrospective analysis of big data's case base was performed on children with acute intussusception in children's hospital affiliated to Chongqing Medical University. And according to the age group of the children, combined with the temperature, air pressure, humidity, wind speed, sunshine hours, precipitation and other meteorological data of the same period in Chongqing, Correlation analysis and stepwise regression were used to study the relationship between incidence of intussusception and meteorological factors. In early childhood, the incidence of acute intussusception in children was 0.000 and 0.000 in spring and summer. The peak onset season of pre-school children was in spring and winter. There was no significant seasonal difference in the number of children with acute intussusception. 2. In general, the monthly incidence of acute intussusception in children and the average monthly temperature were not significantly different from those of children with acute intussusception, and there was no significant seasonal difference in the number of children with acute intussusception. The average monthly wind speed, the total sunshine duration, the total monthly precipitation were positively correlated with the monthly mean air pressure, the total monthly precipitation was 0.405U / r 0.0000.214m / r 0.036F / 0.336U / r 0.001 / 0.312hp ~ (0.002), which was negatively correlated with the monthly mean air pressure and the mean monthly relative humidity (R-0.490P0.000- 0.377p ~ (0.000)), and the average monthly pressure only entered the regression model R2O 0.240Pu 0.000.3The average monthly relative humidity was negatively correlated with the monthly mean air pressure and the mean monthly relative humidity. The monthly incidence of acute intussusception in children was related to the monthly mean temperature, the monthly mean wind speed, the total sunshine duration, the total monthly precipitation of 0.464kg / r 0.464m, and the mean monthly pressure of 0.466g / kg, respectively. The monthly mean relative humidity is negatively correlated with the monthly mean relative humidity of r = -0.784m, r = 0.000m ~ (-1), r = 0.396m / r ~ (0.000) ~ (-1), and the monthly mean air pressure on the regression model is R _ 2N _ (0.614) P ~ (+) 0.0000.4.The monthly incidence of acute intussusception in children is negatively correlated with the monthly mean relative humidity (r ~ (-0.226)), the monthly mean relative humidity (RH), the monthly mean wind speed, the mean wind speed, the mean wind speed, the average wind speed, the average wind speed and the average monthly relative humidity. The total monthly precipitation entered the regression model R2H 0.164 P0. 001t. 5. In preschool children, the monthly incidence of acute intussusception was negatively correlated with the monthly mean wind speed, the monthly mean relative humidity and the monthly mean wind speed entered the regression model R22224P0.0000.0000.6.In school-age children, the incidence of acute intussusception was negatively correlated with the monthly mean wind speed. There was no significant correlation between the monthly incidence of acute intussusception in children and six meteorological factors, and no meteorological factors entered the regression model. Conclusion: the incidence of acute intussusception in Chongqing area has a certain period of time periodicity. The incidence of intussusception was correlated with meteorological factors, but the periodicity of intussusception and the correlation with meteorological factors were different among children of different ages.
