Objective To explore hepatitis B virus(HBV)infection status and its influencing factors among people in Xia-men City,and provide guidance for the formulation of prevention and control measures.Methods A multi-stage stratified sampling method was applied to select 489 participants in 15 age groups from 6 neighborhood committees(villages)in 2 districts of Xiamen City in 2021.A questionnaire survey was conducted and blood samples were collected to test for 5 indi-cators of HBV infection.The HBV infection rate and other indicators were calculated,and logistic regression analysis was used to identify the influencing factors of HBV infection.Results A total of 489 participants were investigated,and 265 of them were female,accounting for 54.19％;age range was mainly 0-5,with 190 participants,accounting for 38.85％;the ma-rital status was mainly unmarried,with 365 participants,accounting for 74.64％;the main occupation was students,with 147 participants,accounting for 30.06％;388 participants(79.35％)received≥3 doses of hepatitis B vaccine.Among 489 survey subjects,115 were HBV infected,with an HBV infection rate of 23.52％and a standardized rate of 40.37％.The lo-gistic regression analysis results showed that farmers(OR=7.301,95％CI:1.018-52.342),6-10 years old(OR=10.859,95％CI:1.012-116.578),11-20 years old(OR=9.583,95％CI:1.138-80.682),21-50 years old(OR=7.214,95％CI:1.016-51.213),and≥51 years old(OR=11.752,95％CI:2.342-58.973)were risk factors for HBV infection;≥ 3 do-ses hepatitis B vaccine(OR=0.137,95％CI:0.021-0.892)was the protective factor of HBV infection.Conclusions The hepatitis B prevention and control efforts in Xiamen City have shown certain effectiveness,but there is still room for im-provement.
