Hurricanes Katrina and Rita significantly increased the number of stillbirths in the Louisiana parishes most affected by the storms, new research suggests.
The 2005 hurricanes resulted in almost 2,000 deaths of children and adults, but researchers have concluded that as many as 205 excess fetal deaths should be added to the toll in the six hardest hit parishes.
Using data on housing damage gathered by the federal government, researchers found that between 117 and 205 stillbirths in the six most severely affected parishes could be attributed to distress caused by the storms — an estimated 17.4 to 30.6 percent of all storm-related deaths in those areas.
Writing in The Journal of Epidemiology & Community Health, the authors acknowledge that their figures are rough approximations. Housing data does not capture the full extent of the loss, and the forced migration of many people complicates the picture. Still, they estimate that for every 1 percent increase in the destruction of houses, there was a 1.7 percent increase in fetal deaths.
"You can have two mothers with equal characteristics — age, race,and so on," said the lead author, Sammy Zahran, an associate professor of demography at Colorado State University, "but if one happens to be in a more severely destroyed area, the risk of still birth is higher."
