Table 3. Logistic regression analyses for the prevalence of HBsAg or anti-HBc in the children*.
HBsAg+ | anti-HBc+/HBsAg− | |||||
aOR | 95%CI | P value | aOR | 95%CI | P value | |
Breastfeeding | 0.99 | 0.28–3.58 | 0.995 | 0.57 | 0.20–1.65 | 0.301 |
Maternal HBeAg carriage | 1.69E8 | 0.00–∞ | 0.992 | 8.93 | 2.76–28.88 | <0.001 |
Child's age | 1.01 | 0.68–1.51 | 0.968 | 1.44 | 0.97–2.13 | 0.068 |
HBV, hepatitis B virus; HBsAg, hepatitis B surface antigen; anti-HBc, antibody against hepatitis B core antigen; aOR, adjusted odds ratio; CI, confidence interval.
Including all the factors different (with a P<0.20) between the breastfed and formula-fed children except the mother's age, as which is not associated with the mother-to-child transmission of HBV [16].
