Objective To investigate the infection situation of AIDS， syphilis and hepatitis B among pregnant women in Yueyang City， to provide formulated treatment and intervention measures to reduce mother-to-child transmission， and to improve the quality of birth population.
Methods A total of 24 546 pregnant women who agreed to take the tests of AIDS， syphilis and hepatitis B from January 2018 to December 2021 in our hospital were retrospectively analyzed.
Results The positive rate of human immunodeficiency virus antibody （anti-HIV） was 0.045%； positive rates of syphilis antibody （anti-TP） and HBsAg were 4.64% and 0.64%， respectively. The positive rates of anti-HIV， anti-TP and HBsAg varied from 2018 to 2021， but the differences were not statistically significant （P>0.05）. The positive rate of HBsAg increased gradually with the increase of maternal age， and the difference was statistically significant （P<0.01）. There were 16 mixed infections among 1 309 positive cases， 15 of which were hepatitis B and syphilis mixed infections.
Conclusion The infection of AIDS， syphilis and hepatitis B in pregnant women in Yueyang City is relatively high. The screening of AIDS， syphilis and hepatitis B before pregnancy is helpful to prevent and reduce the risk of mother-to-child transmission of infectious diseases in time， which is of great significance to eugenic and eugenic education.
