【摘要】：目的:研究重慶地區(qū)小兒急性腸套疊發(fā)病的時間特征及其與氣象因素的相關性。方法:對重慶醫(yī)科大學附屬兒童醫(yī)院收治的急性腸套疊患兒進行大數(shù)據(jù)病例基礎的回顧性分析,并按患兒年齡進行年齡段分組,結合重慶地區(qū)同期的氣溫、氣壓、濕度、風速、日照時數(shù)、降水量等氣象資料,運用相關分析和逐步回歸方法探討腸套疊發(fā)病與各氣象因素的關系。結果:1.重慶地區(qū)小兒急性腸套疊總體及嬰、幼兒期兒童以春夏季發(fā)病為主(P=0.000,P=0.000,P=0.000),學齡前期兒童的發(fā)病高峰季節(jié)是春冬季(P=0.000),學齡期兒童的發(fā)病數(shù)量沒有顯著的季節(jié)差異(P=0.607)。2.總體上小兒急性腸套疊月發(fā)病數(shù)量與月平均溫度、月平均風速、月日照總時數(shù)、月總降水量正相關(r=0.405,P=0.000;r=0.214,P=0.036;r=0.336,P=0.001;r=0.312,P=0.002),與月平均氣壓、月平均相對濕度負相關(r=-0.490,P=0.000;r=-0.377,P=0.000),僅月平均氣壓對進入回歸模型(R2=0.240,P=0.000)。3.在嬰兒期兒童中,小兒急性腸套疊月發(fā)病數(shù)量與月平均溫度、月平均風速、月日照總時數(shù)、月總降水量正相關(r=0.745,P=0.000;r=0.464,P=0.000;r=0.570,P=0.000;r=0.466,P=0.000),與月平均氣壓、月平均相對濕度負相關(r=-0.784,P=0.000;r=-0.396,P=0.000),月平均氣壓對進入回歸模型(R2=0.614,P=0.000)。4.在幼兒期兒童中,小兒急性腸套疊月發(fā)病數(shù)量與月平均相對濕度負相關(r=-0.226,P=0.027),月平均相對濕度、月平均風速、月總降水量進入回歸模型(R2=0.164,P=0.001)。5.在學齡前兒童中,小兒急性腸套疊月發(fā)病數(shù)量與月平均風速呈負相關(r=-0.213,P=0.037),月平均相對濕度、月平均風速進入回歸模型(R2=0.224,P=0.000)。6.在學齡期兒童中,小兒急性腸套疊月發(fā)病數(shù)量與六種氣象因素都沒有顯著的相關性,無氣象因子進入回歸模型。結論:重慶地區(qū)小兒急性腸套疊發(fā)病情況具有一定的時間周期性,發(fā)病情況與氣象因素間普遍存在相關性,但不同年齡段兒童其腸套疊發(fā)病時間周期性及與氣象因素的相關性存在差異。
[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.
