2018年天津市儿童肺炎支原体感染流行病学分析

Epidemiological analysis of children with Mycoplasma pneumoniae infection of Tianjin in 2018

目的了解天津市儿童肺炎支原体(MP)感染情况及流行特征,为肺炎支原体的预防、诊断和治疗提供可靠的依据。方法收集2018年在天津市第三中心医院治疗的1468例急性呼吸道感染(ARI)患儿的临床资料,采用SPSS 20.0统计软件进行统计分析。结果1468例患儿中,肺炎支原体感染患儿占急性呼吸道感染的30.9%,其中女童MP感染率(35.9%)高于男童(27.1%)。MP感染率随着年龄的增长而呈现明显的上升趋势。春、夏、秋、冬季MP感染率分别是26.0%、31.1%、35.0%、30.9%,季节差异无统计学意义(P>0.05)。上呼吸道感染的患儿MP感染率是24.1%,下呼吸道感染的患儿MP感染率是32.1%,两者差异具有统计学意义(P<0.05)。结论MP感染在儿童急性呼吸道感染中所占比例较大,临床上应加强对肺炎支原体的检测及防治。

Objective To understand the infection and epidemiological characteristics of Mycoplasma pneumoniae(MP)for children in Tianjin.And to provide a reliable basis for the prevention,diagnosis and treatment of Mycoplasma pneumoniae.Methods The clinical data of 1468 children with acute respiratory infection(ARI)who were treated in Tianjin Third Center Hospital were collected in 2018.SPSS 20.0 statistical software was used for analysis.Results Among 1468 children,children with Mycoplasma pneumoniae accounted for 30.9%of acute respiratory infections.And the MP infection rate in girls(35.9%)than in boys(27.1%).The MP infection rate shows a clear rising trend with age.The MP infection rates from spring to winter were 26.0%,31.1%,35.0%,and 30.9%,respectively.There was no significant difference in the season(P>0.05).The MP infection rate was 24.1%in children with upper respiratory tract infection and 32.1%in children with lower respiratory tract infection.The difference was statistically significant(P<0.05).Conclusions MP infection accounts for a large proportion of children with acute respiratory infections.The detection and prevention of Mycoplasma pneumoniae should be strengthened in the clinical aspect.
