This study investigates the improvement of the prevention of mother-to-child transmission (PMTCT)
of Human Immunodeficiency Virus (HIV) in China during 2004–2011. A clinic-based prospective study
was conducted among HIV-positive pregnant women and their children in eight counties across China.
Associated factors of mother-to-child transmission were analyzed using regression analysis. A total of
1,387 HIV+ pregnant women and 1,377 HIV-exposed infants were enrolled. The proportion of pregnant
women who received HIV testing increased significantly from 45.1% to 98.9% during 2004–2011.
Among whom, the proportion that received ...

Associated factors of mother-to-child transmission were analyzed using regression analysis. A total of 1,387 HIV+ pregnant women and 1,377 HIV-exposed infants were enrolled. The proportion of pregnant women who received HIV testing increased significantly from 45.1% to 98.9% during 2004–2011. Among whom, the proportion that received antiretroviral (ARV) prophylaxis increased from 61% to 96%, and the corresponding coverage in children increased from 85% to 97% during the same period. In contrast, single-dose nevirapine treatment during delivery declined substantially from 97.9% to 12.7%. Vertical transmission of HIV declined from 11.1% (95% confidence interval [CI]: 5.7–23.3%) in 2004 to 1.2% (95% CI: 0.1–5.8%) in 2011. Women who had a vaginal delivery (compared to emergency caesarian section (odds ratio [OR] = 0.46; 0.23–0.96)) and mothers on multi-ARVs (OR = 0.11; 0.04–0.29) were less likely to transmit HIV to their newborns. Increasing HIV screening enabled timely HIV care and prophylaxis to reduce vertical transmission of HIV. Early and consistent treatment with multi-ARVs during pregnancy is vital for PMTCT.
