Bristol Palin Admits Mistake In Blog Post On Abortion

Bristol Palin apologized and corrected earlier statements she made about fetuses that are aborted because they have been diagnosed with Down Syndrome in a blog post on Friday.

"I’m sorry to say I think I unknowingly passed on incorrect information," Palin wrote.

Palin's initial blog post claimed "ninety-two percent of babies diagnosed with Down syndrome are aborted before they get a chance to take a breath." In her newest post, Palin cites author Amy Julia Becker, who explains that out of all babies conceived with DS, about 50% are actually born:

Overall, it seems that about 70% of babies prenatally diagnosed with DS are aborted, and that the abortion rates vary greatly from region to region across the US. Moreover, lots of women don’t seek prenatal diagnosis, whether out of ignorance or because they don’t want to risk an amnio or because they don’t think the information is necessary. So out of all babies conceived with DS, 50% are actually born. Still a terrible reality that 50% are aborted, but a much better situation than the 8% number implies.

Sarah Palin -- Bristol's mother and the 2008 Republican Vice Presidential nominee -- gave birth to her fifth child, Trig, in April 2008. The Palins released a statement after Trig's birth indicating that they knew the child would have Down Syndrome because of prenatal testing.

Despite her mistake, Palin seems to be faring better than her ex, Levi Johnston. Us Weekly recently reported Johnston -- who is expecting his second child with current girlfriend Sunny Oglesby -- is broke and living with his mother after spending "more than $1 million" on "guns, boats and four-wheelers."
