目的探讨湖北省咸宁市小儿支原体肺炎(MPP)的流行病学特征,为防治提供一定的流行病学支持。方法回顾性分析咸宁市中心医院和咸安人民医院2007年1月～2009年12月三年以来肺炎患儿的临床资料。结果2007～2009年咸宁市小儿肺炎支原体的发病情况具有以下特点:①性别发病率比较:男21.09%,女22.04%,两组发病率差异无统计学意义(P>0.05);②小儿肺炎支原体肺炎发病率有逐年增高趋势,分别为2007年18.71%、2008年22.71%和2009年26.05%;③不同季节的发病率分别为春季17.36%、夏季12.41%、秋季29.59%、冬季25.09%,发病率比较差异有统计学意义(P<0.05);④各年龄段发病率比较:3岁以内13.96%,4～6岁24.10%,7～9岁32.79%,10岁以上20.25%。结论咸宁市小儿肺炎支原体肺炎的发病有逐年增高趋势,冬秋季是本地区儿童支原体肺炎的高发季节;小儿支原体肺炎在3岁以上儿童中发病率较3岁内高。
Objective To investigate the epidemiological characteristics of children with Mycoplasma pneumonia (MPP) in Xianning City, Hubei Province, and to provide some epidemiological support for prevention and treatment. Methods The clinical data of children with pneumonia in Xianning Central Hospital and Xiangan People’s Hospital from January 2007 to December 2009 were retrospectively analyzed.

The incidence rates in different seasons were 17.36% in spring, 12.41% in summer, 29.59% in autumn and 25.09% in winter, respectively The difference was statistically significant (P <0.05). (4) The morbidity of each age group was 13.96% within 3 years old, 24.10% from 4 to 6 years old, 32.79% from 7 to 9 years old and 20.25% over 10 years old. Conclusion The incidence of Mycoplasma pneumoniae pneumonia in children with Xiangying increased year by year.
