Abstract:
Objective: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.
