To understand the influencing factors on the death of infants born to HIV infected mothers in areas with high prevalence of HIV/AIDS in China.


Based on the follow-up cohort study targeting at HIV/AIDS infected pregnant women and their babies initiated in 2004, a survey on the death status and influencing factors on the infants born to HIV/AIDS infected mothers enrolled in this cohort from Jan.2004 to Nov.2007 was carried out during Nov.2008 in seven counties of four provinces in China. A total of 498 pairs of HIV-infected mothers and their infants were enrolled and their related information was collected. Single factor and multiple factors Cox model methods were adopted for data analysis.


The total observed person-years of 498 infants was 406.22, among which, 45 infants died, and the mortality density was 110.78 per 1000 child-year. A single factor Cox model showed, the pregnancy in pre-period of HIV/AIDS and HIV/AIDS period (RR = 1.971, 95%CI: 1.143 - 3.396), living status of the pregnancy (RR = 3.062, 95%CI: 1.097 - 8.550), multipara women (RR = 0.517, 95%CI: 0.278 - 0.961), natural childbirth (RR = 0.561, 95%CI: 0.345 - 0.910), premature labor (RR = 5.302, 95%CI: 2.944 - 9.547), low birth weight (RR = 4.920, 95%CI: 2.691 - 8.994), mother-child pairs taking antiretroviral drugs (RR = 0.227, 95%CI: 0.121 - 0.428) and infants infected HIV (RR = 5.870, 95%CI: 3.232 - 10.660) could affect the infants death. The death of HIV-exposed infants was influenced by various factors. The death risk of infants born to HIV infected mothers who were in the danger of pre-period of HIV/AIDS and HIV/AIDS period was greater than the infants delivered by HIV infected mothers who were in preclinical period of HIV/AIDS (RR = 6.99, 95%CI: 1.92 - 25.64). The death risks were greater in the group that the women whose CD4(+)TLC count number lower than 200 cells/microl (RR = 2.05, 95%CI: 1.01 - 4.15). The infants whose mothers had no ARV treatment had higher possibility to die than the others (RR = 6.17, 95%CI: 1.62 - 23.26). The death risk of premature delivered infants was 2.87 times of mature delivered infants (95%CI: 1.12 - 7.35). The death risk of HIV/AIDS infected infants was 9.87 times of the HIV/AIDS uninfected infants (95%CI: 3.81 - 25.62).


Some measurements including improving HIV-infected pregnant women's immunity, reducing mother to child transmission of HIV and premature birth, low birth weight are beneficial to reducing infant mortality.
