Analysis of Acute Mycoplasma Pneumoniae Infection in Jinniu District of Chengdu From 2017 to 2018

目的分析2017-2018年成都市金牛区急性肺炎支原体感染情况,为制订防控策略提供依据。方法采集2017-07-01/2018-07-01成都市金牛区急性呼吸道感染患者血清,以被动凝集法检测血清肺炎支原体IgM抗体情况,计数资料以n(%)表示,组间比较行χ~2检验,检验水准为α=0.05。结果共检测16 720例急性呼吸道感染患者血清,男性10 147例,女性6 573例,肺炎支原体IgM抗体阳性4 018例(24.03%),其中肺炎支原体IgM抗体阳性男性2 295例,女性1 723例,女性肺炎支原体IgM抗体阳性率(18.74%)高于男性(13.62%),差异具有统计学意义(χ~2=28.251,P<0.01)。7个年龄段(<1、1～、4～、14～、20～、40～、≥60岁)阳性率分别为12.12%(181/1 493)、20.38%(929/4 558)、28.97%(2 456/8 477)、28.54%(151/529)、22.40%(123/549)、16.01%(57/356)和15.96%(121/758),差异有统计学意义(χ~2=308.860,P<0.01)。春季、夏季、秋季、冬季阳性率分别为23.89%(1 056/4 421)、19.51%(783/4 014)、22.79%(904/3 967)和29.53%(1 275/4 318),差异有统计学意义(χ~2=119.872,P<0.01)。结论成都市金牛区急性呼吸道肺炎支原体感染患者女性多于男性,儿童和青少年较为多见,发病存在季节性差异,冬季发病率最高。

Objective To analyze the situation of acute mycoplasma pneumoniae infection in Jinniu district of Chengdu from 2017 to 2018, and to provide a basis to formulate the prevention and control strategies. Methods The serums of patients with acute respiratory infections in Jinniu district of Chengdu from July 1 st, 2017 to July 1 st, 2018 were collected. The serum mycoplasma pneumoniae IgM antibody was detected by passive agglutination method and statistical analysis was performed with SPSS 20.0 software, the inspection level was that α=0.05. Results About 16 720 patients with acute respiratory infections were tested for serum. There were 10 147 males and 6 573 females,4 018(24.03%) of positive antibody for mycoplasma pneumoniae IgM,there were 2 295 males with positive mycoplasma pneumoniae IgM antibody and 1 723 females of that, the positive rate of IgM antibody in women with mycoplasma pneumoniae(18.74%) was higher than that of men(13.62%)(χ^2=28.251,P<0.001). The positive rates were 12.12%(181/1 493),20.38%(929/4 558),28.97%(2 456/8 477),28.54%(151/529),22.40%(123/549),16.01%(57/356), 15.96%(121/758) respectively from 7 groups of age(less than 1 year old, 1 to 3 years old,4 to 13 years old,14 to 19 years old,20 to 39 years old,40 to 59 years old,greater than or equal to 60 years old),the difference was statistically significant(χ^2=308.860,P<0.01). The positive rates were 23.89%(1056/4 421), 19.51%(783/4 014), 22.79%(904/3 967) and29.53%(1 275/4 318), respectively in the spring, summer, autumn and winter, the difference was statistically significant(χ^2=119.872, P<0.01). Conclusion There are more in women than males infected with the mycoplasma pneumoniate in Jinniu district of Chengdu. Children and adolescents are infected more. There are seasonal differences in the incidence, winter had the highest incidence.
