摘要目的:本研究旨在系统分析中国健康人群腮腺炎病毒（MuV）IgG抗体水平，并结合中国的免疫策略和腮腺炎发病情况进行免疫效果评价。方法:采用计算机检索万方数据知识服务平台、中国知网、中国生物医学文献服务系统、PubMed和Web of Science数据库有关中国健康人群MuV IgG抗体水平的研究，检索时限为2000年1月1日至2022年3月31日。采用乔安娜·布里斯研究所横断面研究评价工具对纳入的研究进行质量评价，使用R 4.1.2和Stata 16.0软件进行数据分析，并对不同年代、地区、性别、免疫状况、年龄人群抗体水平进行分层分析。结果:共纳入69篇文献（中文66篇、英文3篇），涉及全国26个行政区的97 034名健康者。结果显示，中国健康人群MuV IgG抗体阳性率为74.87%（95% CI：71.41%~78.17%），抗体几何平均浓度为177.83 U/ml。累积Meta结果显示，随着时间推移，MuV IgG抗体阳性率有所增加。亚组分析显示，中国人群MuV IgG抗体阳性率随着年龄和疫苗接种剂次的增加而升高，0~17月儿童抗体阳性率仅为32.42%（95% CI：25.96%~38.88%）；华北地区报告阳性率最高，为81.45%（95% CI：75.76%~87.14%）。此外，城市人群MuV IgG抗体阳性率高于乡村人群（ P<0.01）；女性MuV IgG抗体阳性率高于男性（ P<0.01）。 结论:疫苗纳入扩大免疫规划以来，中国腮腺炎抗体阳性率有所升高，不同地区和人群的抗体水平存在差异，未来仍需进一步提高中国健康人群的MuV抗体水平，以更好地预防和控制腮腺炎的流行。

abstractsObjective:To systematically analyze the IgG seroprevalence of mumps virus (MuV) in Chinese healthy population, and evaluate the immune effect based on the immunization strategy and the incidence of mumps in China.Methods:The databases of Wanfang data knowledge service platform, China National Knowledge Infrastructure, SinoMed, PubMed, and Web of Science were searched to retrieve literature about the level of MuV IgG antibody in Chinese healthy population from January 1, 2000, to March 31, 2022. The quality of eligible papers was appraised by using the cross-sectional study evaluation tool from Joanna Briggs Institute. Data analysis, including the stratified analysis of the IgG seroprevalence in different generations, regions, gender, immunization status, and age groups, was performed using R 4.1.2 and Stata 16.0.Results:A total of 69 papers (66 in Chinese and 3 in English) were included, involving 97 034 people in 26 administrative regions across China. The results showed that the MuV IgG seroprevalence in Chinese healthy population was 74.87% (95% CI: 71.41%-78.17%) and increased over time according to the cumulative Meta-analysis. The geometric mean concentration of antibody was 177.83 U/ml. The subgroup analysis showed that the positive rate of MuV IgG antibody increased with the age and vaccination doses. The positive rate of antibody in children aged from 0 to 17 months was only 32.42% (95% CI: 25.96%-38.88%). The highest positive rate was reported in North China, about 81.45% (95% CI: 75.76%-87.14%). In addition, the positive rate of MuV IgG antibody in urban population was higher than that in rural population ( P<0.01) and the positive rate of MuV IgG antibody in women was higher than that in men ( P<0.01). Conclusion:Since the vaccine was included in the expanded immunization program, the positive rate of mumps antibody in China has increased, and the antibody level varies in different regions and populations. It is still necessary to improve the MuV antibody level in Chinese healthy population, so as to better prevent and control the mumps epidemic in the future.
