Cross-sectional investigation on HBV infection among pregnant women

Objective To explore the infection state,infection modes and influencing factors of HBV in pregnant women.Methods Hepatitis B virus markers(HBVM) in serum of pregnant women were detected by ELISA.Results The total of HBV infection and positive of HBsAg in pregnant women were 8.63%(264/3 060) and 8.19%(251/3 060).Twelve modes were confirmed and 35.98%(95/264) in the mode of positive of HBsAg,anti-HBe,anti-HBc.No significant difference was confirmed in the positive rate of HBsAg in different occupation groups and age groups(P0.05).The infection of HBV in pregnant women with vaccine was lower(6.72%,78/1 161) than those without vaccine(11.79%,110/933),(P0.01).Conclusion Infection of HBV is present in some pregnant women and the mode of HBsAg(+),anti-HBe(+),anti-HBc(+) is more common.The injection of HBV vaccine is identified as one of the valid methods to prevent HBV infection in pregnant women.
