小儿肺炎支原体感染与年龄、性别的关系探讨

The Relationship of Age and Gender to Mycoplasma pneumonia Infection in Children

目的通过对呼吸道感染患儿血清中肺炎支原体抗体的检测,调查小儿肺炎支原体抗体感染的状况及与患儿性别、年龄的关系。方法采集患儿静脉血、血清做倍比稀释,用日本富士肺炎支原体诊断试剂盒SERODIA-MYCOⅡ做颗粒凝集实验。结果在5155例呼吸道感染患儿中共检出肺炎支原体抗体阳性病例2831例,阳性率为54.9%,男、女患儿阳性率分别为49.6%和63.3%,男女差别具有统计学意义。1岁以内患儿阳性率明显低于其他年龄段,其他年龄段之间阳性率无明显差异;门诊与住院患儿阳性率分别为65.5%和43.2%。结论肺炎支原体感染好发于1岁以上儿童,女童感染机会高于男童,门诊患儿阳性率高于住院患儿。肺炎支原体抗体检测可作为小儿呼吸道感染的常规检测项目。

Objective To investigate the relationship of age and gender to Mycoplasma pneumonia infection in children. Method Serum samples were collected from children for the detection of antibody against Mycoplasma pneumon/a by particle agglutination test using SERODIA-MYCO Ⅱ kit （FUJI, Japan）. Result The positive cases of antibody of Mycoplasma pneumonia are 2831 out of 5155 were seropositive, with a overall positive rate of 54.9%. The positive rate of male （49.6%） was significantly lower than that of female （63.3%）. The positive rate of below 1 year old was obviously lower than those of any other age groups while the positive rates of these age groups showed no significant difference. The positive rates of outpatients and hospitalized patients were 65.5% and 43.2%, respectively. Conclusion The infection of Mycoplasma pneumonia was more common among the children over 1 year old. The infective rate of girls was higher than that of boys in children. Outpatients had higher positive rate than those in hospital.
