摘　　要：目的调查小儿肺炎支原体（MP）感染发病率与性别、年龄以及季节的关系。方法采用被动凝集法进行血清肺炎支原体IgM（MP-IgM）抗体检测。结果1701例肺炎患儿的样本，其中阳性样本数共569例，阳性率为33．5％。男性、女性肺炎患儿MP-IgM阳性率分别为30．1％、37．8％，两者差异有统计学意义（P〈0．01）。0～1岁组婴儿MP-IgM阳性率为5．8％；2～3岁组幼儿MP-IgM阳性率为35．3％；4～6岁学龄前期儿童MP-IgM阳性率为43．3％；7～14岁学龄期儿童MP-IgM阳性率为52．9％。各组患儿MP-]gM阳性率差异均有统计学意义（P〈0．01，P〈0．01，P〈0．05）。2008年与2009年MP-IgM阳性率差异无统计学意义（P〉0．05），而与2007年差异有统计学意义（P〈0．01）。发病季节分布上，2007年流行年四季MP感染率无明显差异；其他两年春季MP感染率较低，另外三季无明显差异。结论MP感染好发年龄仍为学龄前和学龄期儿童；女性儿童感染机会高于男性儿童；流行季节为春季。Objective To investigate relationship between infection rate of Mycoplasma pneumoniae（MP） in children with corresponding gender, age and season. Methods Mycoplasma pneumoniae IgM （MP-IgM） antibody level in serum was measured utilizing method of passive particle agglutination. Results From 2007 to 2009, MP-IgM antibodies among total 1 701 children with pneumoniae were detected in the study, of which 569 cases showed MP-IgM antibodies positive （569/1701,33.5%）. The MP-IgM positive rate in male and female patients were 30. 1% and 37. 8% respectively and the difference was statistically significant （ P 〈 0.01 ）. The MP-IgM positive rates in 0 - 1 year-old group,2 - 3 year-old group ,4 - 6 year-old group and 7 - 14 year-old group were 5.8% ,35.3% ,43.3% and 52.9%, respectively. The disparities of MP-IgM positive rate between the groups was statistically significant （ P 〈 0.01, P 〈 0.01 and P 〈 0.05, respectively）. The differences of MP-IgM positive rates during the peroid of 2007,2008 and 2009 were statistically significant（ P 〈 0.01 ）, but no difference was significantly exhibited during the peroid of 2008 verse 2009 （P 〉 0.05 ）. As for onset distribution of season, in year 2007, MP infection rates between the individ- ual seasons were not statistically different. Conclusion MP infection was mainly prevailed in those whose ages were over three years old. MP infection was inclined to occur in female children than in male and the prevalent season was the Spring.
