Kristin Casas, M.A. 2012
According to Kristin Casas’s research, over 400,000 children worldwide
in 2007 acquired HIV from their mothers during the pregnancy process or
through breastfeeding. Casas’s thesis explored the complex issues
involved in determining whether an HIV-infected mother should breastfeed
or use formula. In resource-rich countries where formula is safe and
readily available it is an easy choice. However, in resource-poor areas,
the choice is complicated by the high infant mortality rates for those
who do not breastfeed. Casas also found that the highest transmission of
HIV occurred in infants who received both breast milk and formula. (The
intermittent use of formula inflames the baby’s gut, increasing the
likelihood of contracting HIV.) For mothers who choose to breastfeed,
there is highly active antiretroviral therapy (HAART) to reduce the
chances of the mother transmitting HIV to her nursing baby. By
preserving breastfeeding in low-income contexts with the aid of HAART
treatment, infants may be able to live longer, healthier, HIV-free lives
compared to their formula-fed counterparts. The choice of an
HIV-infected mother of whether to breastfeed or bottle-feed a baby is
very convoluted. Casas explains, “Although I set out to discover what
the safest feeding method would be for an infant born to an HIV-infected
mother, the results from studies revealed that it differs for each
individual.”
