Abstract
English (OpenAlex)
Background: The detection of hepatitis B surface antigen positivity in pregnant women before delivery is crucial to preventing mother-to-child transmission of hepatitis B virus. Aims: This study aimed to evaluate the status and rate of testing for hepatitis B surface antigen, rate of hepatitis B surface antigen positivity, hepatitis B surface antigen positivity distribution rate by age, and changes in hepatitis B surface antigen positivity rate in pregnant women over the study period. Methods: We conducted a multicentre, cross-sectional, descriptive study covering the period January 2005 to June 2019 for 2 145 668 pregnant women from 27 provinces in all 7 regions of Turkey, collected using Microsoft Excel before statistical analysis. Results: We found that 1 012 593 (47.1%) pregnant women were tested for hepatitis B surface antigen over the 15-year period, out of which 11 471 (1.1%) were hepatitis B surface antigen-positive. Overall, 97% of the hepatitis B surface antigen positive women were born before 1998, the year that national HBV vaccination was launched in Turkey. The rate of hepatitis B surface antigen positivity in that group was 1.1%, compared with 0.3% among women born after 1998. Conclusion: There was a downward trend in the hepatitis B surface antigen positivity rate among pregnant women in the younger age groups, especially among those born after universal hepatitis B vaccination was inaugurated, and low rate of HBsAg testing during pregnancy.
