The HBsAg positive rate among pregnant women decreased from 5.23% in 2015 to 3.47% in 2022, thus showing a decreasing trend over time ( χ 2 trend = 84.588, P < 0.01) (see Table 2 ; Fig. 2 A).

We found that different HBsAg and HBeAg carrier statuses were highly correlated with ICP (aOR = 3.401, 95%CI (2.974–3.890) and 1.155, 95%CI (0.855–1.561), and showed an increasing trend with higher HBV infectious intensities.
