Hurricane Katrina Led to Increased Miscarriage and Preterm Births for ART Patients

Reviewing national statistics on the results of Assisted Reproductive Technology (ART) cycles from around the country, researchers have found that both miscarriage and preterm births among ART patients increased in the months following Hurricane Katrina.
Reporting their findings at the 67th Annual Meeting of the American Society for Reproductive Medicine (ASRM) in Orlando, the team of researchers from around the country reviewed the outcomes data compiled annually by the Society for Assisted Reproductive Technology (SART). They found that ART cycles initiated pre- Hurricane Katrina were 87% less likely to sustain a 1st trimester miscarriage and 63% less likely to sustain a miscarriage at less than 16 weeks, than post Katrina cycles. Singleton pregnancies were also more likely to deliver pre-term post Katrina than they had been before the storm. These variations remained even as potential confounding factors, such as age or diagnosis were controlled for using statistical methods. Perhaps most surprising is that the loss rate was the same across the entire country, not just in the areas directly affected by the storm.
“It is clear we still have a lot to learn about human reproduction. But this kind of study points out the importance that external factors can have on attempts to successfully initiate and carry a pregnancy to full term,” said R. Stan Williams, MD, President of the Society for Assisted Reproductive Technology.
