    Objective: To track the level of serum antibodies in Fuzhou residents and analyze the possible influencing factors of serum antibodies, so as to provide a scientific basis for the adjustment of population immunity and prevention and control strategies. Methods: Residents in the Fuzhou community who had symptoms of covid-19 infection or who had tested positive for nucleic acid or antigen since December 2022 were selected for the questionnaire survey and their sera were collected to analyze the trend of antibody changes, the antibody level was divided into high antibody group and low antibody group according to the literature data. The possible influencing factors of serum antibody level was analyzed by multivariate logistic regression model.Results: A total of 2,521 Fuzhou residents were adopted in the study, including 223 in the high antibody group and 194 in the low antibody group. A univariate analysis showed that, there were significant differences in age (Z=-4.028, P<0.00) , occupation ( 2 =18.591, P=0.005) , typical symptoms after the first infection ( 2 =9.784, P=0.002), history of surgery ( 2 =29.542, P<0.001), symptoms lasting more than 2 weeks after the first infection ( 2 =4.887, P=0.027), smoking ( 2 =18.524, P<0.001) and drinking ( 2 =19.578, P<0.001) between the high antibody group and the low antibody group.
