Objectives
Provide a general overview of perinatal HIV transmission
Give a demographic description of HIV/AIDS infected women delivering in Texas
Present findings on factors influencing perinatal HIV transmission
Offer a summary of findings
Scope of Epidemic in the United States among Women-2005 Women represented 27% of persons living with
HIV/AIDS
127,150 women known to be living with HIV/AIDS 64% are African American women
5,000-7,000 HIV+ women give birth each year This figure represents between 4 to 5 percent of
women living with HIV/AIDS
Scope of Epidemic in the United States among Children-2005 9,078 children diagnosed with AIDS (through 2005)
>90% were perinatally infected
6,109 estimated children perinatally infected and living with HIV/AIDS in 2005 Perinatally infected children account for 1% of all
people living with HIV/AIDS 65% of perinatal infections are among Blacks 141 HIV/AIDS perinatal cases diagnosed in 2005

Women Infected Children
Other Factors Potentially Contributing to Perinatal HIV Infection
Alcohol/Tobacco and Substance Use for HIV+ Women Delivering in Texas, 2003-2005
Indication of alcohol and/or tobacco use (10%, 99)
Indication of substance use (11%, 109) Of the 109 women with an indication of substance use
only 69% received a toxicology screen Only 33% of those with an indication of substance use
were referred for treatment during or after pregnancy
Positive toxicology screen (7%, 69) 68% received inadequate prenatal care Only 46% received 3-Part ART 22% of infected children among women with a positive
toxicology screen
Summary of Findings
Summary of Perinatal Infection in Texas Women delivering in Texas are predominantly Black Proportion of children infected is less among those
diagnosed prior to pregnancy Proportion of children infected is higher among those
receiving Inadequate prenatal care and no antiretroviral therapy.
Proportion of children infected is higher among those that are breastfed.
Prevention measures among women delivering an infected infant For 83% of infected infants-2 or less interventions For 18% of infected infants-3 interventions
