Resumo: OBJECTIVE: To explore the impact of being informed of HIV infection before or after pregnancy on the prevention of mother-to-child transmission (PMTCT) HIV interventions uptake. METHODS: From 2005 to 2009, a tatal of 5552 HIV-infected pregnant women and their 5894 pregnancies in Henan, Guangxi, Yunnan and Xinjiang province were investigated using the method of a cohort study. The social-demographic characters (the objects were divided three age groups 15-, 25-, 35-49), the period identified to be HIV positive, the outcome of pregnancy and the PMTCT interventions including uptake of antiretroviral drugs (ARVs) were investigated. Through single-factor and non-conditional logistic regression model, the factors influencing the utilization of PMTCT services were analyzed. RESULTS: Of HIV-infected pregnant women, 84.5% (4979/5894) were under 35 year-old, and 56.0% (3108/5552) of them were Han group and the percentage of peasant or unemployment was 85.1% (4727/5552). 86.8% (4815/5552) of these women had junior high school education or less, and the proportion of women knowing HIV infection before the pregnancy was 31.2% (1836/5894). Of HIV positive pregnant women, 31.7% (1869/5894) chose to terminate the pregnancy artificially, and the percentage was 43.8% (805/1836) among those knowing HIV infection before pregnancy. The proportion of the ARVs uptake among HIV positive maternities who delivered was 80.0% (3046/3808), while the percentage among those knowing HIV positive before pregnancy was 92.3% (883/957), which was much higher than it (75.9% (2163/2851)) among the pregnant women knowing HIV infection just during the pregnancy (χ(2) = 120.39, P < 0.05). The results of multivariate analysis showed that the proportion of ARVs' uptake was high among those HIV positive pregnant women knowing to be HIV-infected before pregnancy (versus knowing to be HIV-infected after the pregnancy, OR = 3.91 (95%CI: 3.03 - 5.05)) and age of 15 to 24 year-old (versus age of 35 - 49 year-old, OR = 0.75 (95%CI: 0.57 - 0.98)). CONCLUSION: It will promote the HIV-infected pregnant women to receive the PMTCT intervention services if they know their HIV sero-status before pregnancy.
